Detailed Description

The invention is described in detail below with reference to the figures and specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Example one

For the situation that the electromechanical or power equipment needs to be turned over for multi-angle detection in the online detection of the production process of the electromechanical or power equipment, the embodiment provides an electromechanical equipment online detection system, and a main model of the system is shown in fig. 1. On the left side of the figure is an input transport system 200 and on the right is an output transport system 300, such as a production line conveyor belt or chain. The traverse hoisting maintenance system is vertically arranged between the input transmission system 200 and the output transmission system 300, namely, the tail end of the input transmission system 200 corresponds to the head end of the traverse hoisting maintenance system, and the transmission tail end of the output transmission system 300 corresponds to the transmission head end of the traverse hoisting maintenance system.

As can be seen, the lateral hoist system comprises a lateral outer frame 100, the outer frame 100 having a truss 101 at the top and a plurality of pairs of fixed uprights 102 at the bottom. The area between an adjacent pair of stationary posts 102 forms a channel as an inspection station 400. A cross rail 103 is fixed to the outer frame 100 below the top truss 101 in the lateral direction. Meanwhile, the transverse rail 103 is distributed with hoisting units (the hoisting units are not shown in fig. 1) capable of transversely moving.

The number of the hoisting units is one or more. When the number of the hoisting units is one, the hoisting units can be dragged to and fro through a steel wire rope arranged along the transverse rail 103, so that the hoisting units can move to reach the position above the appointed station. Usually, a position sensor or a corresponding component, such as a proximity switch or a laser positioning instrument, is mounted above the corresponding station. When a plurality of hoisting units are arranged, each hoisting unit is driven by the traction mechanism to reciprocate horizontally, and each hoisting unit is vertically and downwards connected with a hoisting tool for grabbing the detected equipment and transferring the detected equipment to the corresponding maintenance unit.

The lifting appliance of each lifting unit can be a mechanical arm or a lifting hook. The hoisting or grabbing is carried out manually or automatically. The top girder 101 of the outer frame 100 is extended to both sides so that the hoist unit can be moved above the input and output transfer systems 200 and 300 and above the respective stations therebetween.

The number of the stations is determined according to actual needs, for example, according to n steps of an inspection process, where n is a natural number greater than 1, and n inspection units shown in fig. 2 are sequentially arranged between the input conveying system 200 and the output conveying system 300. Between adjacent service units is a detection station 400.

As shown in fig. 2, each service unit at least comprises a fixed upright post 102 located at the front and rear sides, two walking upright posts 11 located at the front and rear sides are arranged inside the fixed upright posts 102 located at the front and rear sides, and the walking upright posts 11 at the front and rear sides are parallel to each other. And a longitudinal controllable driving mechanism for driving the walking upright post 11 to simultaneously inwards and outwards is also arranged.

The structure of the longitudinal controllable driving mechanism is as follows: a longitudinal rail 12a is provided at the bottom (on the bottom plate 12) provided between the fixed uprights 102, bases 11a are provided below the pair of traveling uprights 11, respectively, rail wheels (not shown) are mounted below the bases 11a, and the rail wheels are fitted to the rails 3. Meanwhile, a screw 13 is installed between the fixed upright posts 102, two ends of the screw 13 are installed in the shaft holes of the corresponding upright posts through shaft sleeves or bearings, the screw 13 passes through the horizontal screw hole in the base 11a to form a screw rod structure, and one end of the screw 13 extends out of the fixed upright posts 102 to be in transmission connection with the longitudinal movement driving motor 14. Further, a guide rod 15 is fixed to the upper ends of the two fixed columns 102, and a slide bearing 15a is mounted to the upper ends of the traveling columns 11 with a guide hole provided, respectively, and the slide bearing 15a is fitted to the outside of the guide rod 15. Thus, the walking post 11 can be driven by the screw 13 to longitudinally translate along the guide rod 15. The screw 13 can restrain the two walking columns 11 at the original positions after stopping rotating.

The guide rod 15 or the screw 13 is coated with lubricant oil and sealed, for example, a dust sealing bag is sleeved on the outer sides of the guide rod 15 and the screw 13, a supporting spring with a larger screw pitch and a smaller diameter is sleeved in the dust sealing bag, and the supporting spring is arranged between the two walking columns 11 and between the two fixed columns 102.

As can also be seen in fig. 2, a controllable gripping mechanism 16 is mounted in each case in the middle of the inner side walls of the walking uprights 11. The controllable gripping mechanism 16 may take any form so as to be able to support and hold the two ends of the respective device. The controllable grasping mechanism 16 is provided with a connecting base at the rear end thereof, and the controllable grasping mechanism 16 is connected with a rotating motor 19 for driving the controllable grasping mechanism to rotate. Specifically, at least three vertical guide holes 11b are formed in the walking upright post 11, the rear seat 18 is fixed to the vertical guide holes 11b through fixing wires 18, and the height of the rear seat can be adjusted and fixed after the fixing wires 18 are loosened. A rotating electric machine 19 is fixed to the rear seat 17. The rotating shaft of the rotating motor 19 penetrates through the vertical guide hole 11b in the middle of the walking upright post 11. The rotating shaft end of the rotating motor 19 is provided with a connecting body which is fixed with the connecting seat, so that the rotating motor 19 can drive the controllable grasping mechanism 16 to rotate along the rotating shaft of the motor.

In addition, after the two controllable grasping mechanisms 16 which are oppositely arranged grab the corresponding detected equipment, the gravity of the equipment is transmitted to the rear seat 17 through the connecting seat. The rear seats 17 are firmly fixed to the respective walking uprights 11. In order to enhance the fixing strength of the rear seat 17, transverse grooves may be further provided at intervals in each of the vertical guide holes 11b of the travel pillar 11 to support the corresponding fixing wires 18 to prevent them from slipping downward in a loose state.

Therefore, in the embodiment, the hoisting unit and the reciprocating driving mechanism thereof can be used for transferring the device to be detected from the input transmission system 200 to each detection station 400, sequentially transferring the device to be detected to each detection station 400, and finally transferring the device to be detected to the output transmission system 300. As shown in fig. 9, after the device to be tested is lifted to the corresponding testing station 400, the device is positioned by the horizontal and vertical position sensors so as to be located between the front and rear controllable gripping mechanisms 16 (the height of the controllable gripping mechanism 16 is adjusted in advance and then fixed at a specific position). According to the detection requirement, the rotating motor 19 is controlled by the controller to rotate, so that the detected device rotates along the center of the detected device. And releasing the detected device in a reverse operation, and transferring the device to the next detection process or outputting the device by the hoisting unit. Therefore, the detection system can realize the transverse transfer function of a full-automatic production line, the multi-station turnover function at any angle and the purpose of in-situ detection of detection personnel. The detection efficiency can be obviously improved, and the condition of missing detection can be avoided.
