Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the specific embodiments.

In the following description of the direction, the direction of the RGV car is taken as the front, and vice versa, the left side viewed by the operator standing in front of the RGV car is taken as the left side, and the right side is taken as the right side.

An on-line wheel-track conveying system, as shown in fig. 4, includes a conveying rail 200 laid in a factory building and an RGV car 100 capable of sliding along the conveying rail 200. The height of the conveying guide 200 is set to 1-2cm so that the normal operation is not affected.

In this example, the RGV car 100 includes a car body 1 and a wheel assembly mounted at the bottom of the car body 1, and the RGV car 100 further includes a lever mechanism mounted on the car body 1 for pushing the wheel set 400 to rotate, as shown in fig. 1, 2 and 3.

Specifically, the deflector rod mechanism at least comprises a group of deflector rod assemblies, in order to ensure that the wheel pair 400 cannot deviate and tilt in the transfer process, the deflector rod mechanism comprises two groups of deflector rod assemblies, the two groups of deflector rod assemblies are arranged above the vehicle body 1 at intervals along the width direction of the vehicle body 1, each group of deflector rod assemblies comprises a pair of deflector rods 2 arranged at intervals along the front-back direction, the two deflector rods 2 in each group of deflector rod assemblies can rotate in a vertical plane, each deflector rod comprises a working position and a non-working position, and when the RGV trolley 100 loads the wheel pair 400, the two deflector rods 2 in each group of deflector rod assemblies rotate to the working positions to respectively abut against two sides of the wheel pair 400 in the radial direction; when the RGV trolley 100 is unloaded, the two deflector rods 2 in each set of deflector rod assemblies rotate in opposite directions to the non-working position to be separated from the wheel pair. Of course, the deflector rod assembly can also have one group or a plurality of groups according to the actual situation. Through the deflector rod assembly, when the RGV trolley 100 reaches the wheel pair 400 to be transported, the deflector rod 2 rotates to the working position, then the RGV trolley 100 travels on the conveying guide rail 200, and the deflector rod assembly drives the wheel pair 400 to rotate.

Of course, the two sets of deflector rod assemblies can also be installed on two sides of the vehicle body 1 in the width direction, and as shown in fig. 3, when the two sets of deflector rod assemblies are installed on the sides of the vehicle body 1, the height of the vehicle body 1 can be further reduced, and it is ensured that the RGV car can pass through under the wheel axle of the wheel pair 400.

Concretely, every group driving lever subassembly all includes a worm 3 and installs on automobile body 1, worm wheel 4 with worm 3 engaged with, worm wheel 4 and driving lever 2 in every group driving lever subassembly are in quantity and position one-to-one, driving lever 2 is fixed to be installed on the worm wheel 4 rather than corresponding, the axial lead direction of worm 3 sets up with the length extending direction looks parallel of automobile body 1, every group driving lever subassembly is still including installing driving motor I5 on automobile body 1, this driving motor I5's output is connected to rather than corresponding worm 3 on.

In this example, two shift levers 2 in each group of shift lever assemblies are arranged on the vehicle body 1 in a mirror symmetry manner, and the two worm gears 4 in each group of shift lever assemblies rotate in opposite directions. When the wheel pair 400 is transported, the driving motor I5 drives the worm 3 to rotate around the axis line direction of the worm, the two worm wheels 4 meshed with the worm 3 rotate to drive the shifting rods 2 corresponding to the worm to rotate relatively to the working position, and when the wheel pair is in no-load state, the driving motor I5 drives the worm 3 to rotate in the opposite direction to further drive the worm wheels 4 to rotate, so that the two shifting rods 2 corresponding to the worm 3 rotate in the opposite direction to the non-working position. By adopting a worm and gear structure, the driving lever 2 can play a self-locking function when in a working position, and the driving lever 2 is ensured not to deform in the transferring process of the wheel pair 400.

In order to enable the RGV carriage 100 to be threaded through from below the wheel axle of the wheel pair 400, the height of the body 1 of the RGV carriage 100 is here lower than the height of the wheel axle of the wheel pair 400 to be transported from the ground.

In order to prevent the shifting rods 2 from sliding friction with wheel shafts on the wheel pairs 400 and abrasion to the wheel shafts in the transferring process of the wheel pairs 400, rollers 6 are arranged on two opposite side surfaces of the shifting rods 2 in each group of shifting rod assemblies, and a plurality of rollers 6 are arranged at intervals along the length direction of the shifting rods 2. In order to prevent the rollers 6 from being in direct hard contact with the axle and causing damage to the axle, the rollers 6 are made of a flexible material.

In this example, the wheel assembly includes two sets of wheels 7 respectively installed at the front end of the vehicle body 1 and the rear end of the vehicle body 1 and driving motors II 8 installed on the vehicle body 1 and corresponding to the two sets of wheels 7 in number and position one by one, a gear I9 is installed on the output end of the driving motor II 8, each set of wheels 7 includes two wheels 7 installed on the left and right sides of the vehicle body 1, the two wheels 7 are connected through a connecting shaft, and a gear II 10 engaged with the gear I9 is fixedly installed on the connecting shaft. Through gear engagement, the running condition of the trolley can be well controlled.

In this example, in order to prevent the RGV car 100 from deviating from the guide rail during operation and causing derailment, the bottom of the RGV car 100 is further provided with a plurality of derailment prevention wheels 11, and the horizontal plane of the lowest end of the derailment prevention wheels 11 is higher than the horizontal plane of the lowest end of the wheel 7. During normal operation, the anti-derailing wheel 11 is emptied and cannot contact with the ground, and only when the wheel 7 deviates from the guide rail, the anti-derailing wheel 11 contacts with the guide rail and continues to drive the vehicle body 1 to move forwards.

In this example, the surface of the wheel 7 is coated with a layer of polyurethane material. By coating the surface with a polyurethane material, the frictional force between the wheel 7 and the guide rail can be increased.

Because the wheel pair 400 to be transported carries the pinion, in order to prevent the RGV car 100 from carrying the wheel pair 400, the height of the car body 1 is higher than the height of the lowest point of the pinion from the ground, so that the RGV car 100 cannot penetrate through the wheel shaft, and therefore, grooves 12 are formed in the front side plate and the rear side plate of the car body 1.

In this example, the conveying rail 200 includes a plurality of cross rails perpendicular to each other, the wheel pair 400 transferring and conveying system further includes a steering mechanism 300 installed between the cross rails, the steering mechanism 300 includes an underframe and a lifting tray installed on the underframe, and the tray is installed on the underframe and can rotate around the axis direction of the tray. The RGV trolley 100 reaches the junction of the cross guide rails through the steering mechanism 300, and when the direction needs to be changed for operation, the steering of the RGV trolley 100 and the wheel pair 400 can be realized by lifting the tray and then rotating the tray by 90 degrees.
