The arrangement of the inner box body 17 can enable the tool switching mechanism 4, the longitudinal and transverse displacement mechanism 3, the telescopic mechanism 6, the clamping mechanism 7 and the rotating mechanism 8 which are arranged inside to realize the adjustment of the angle and the height along with the inner box body 17, and the inner box body 17 realizes the adjustment of the height and the angle under the action of the position fine adjustment mechanism 5.

As shown in fig. 7, the support roller mechanism 2 includes a telescopic power member 22 mounted on the outer side wall of the outer box, a link member 24 connected to the telescopic power member 22 in a transmission manner, and a power roller member 26 mounted on the link member 24, wherein the telescopic power member 22 is used for folding and extending the power roller member 26 under the action of the telescopic power member 22, so that the power roller member 26 can be attached to the inner wall of the hoistway.

Support roller mechanism 2 wherein through folding and extension two kinds of states, realize adjusting the distance of power roller member 26 and well wall, realize keeping the stable effect of equipment, can adapt to the not unidimensional well, adaptability is high.

As shown in fig. 1, the hoisting mechanism 1 includes a hoisting motor 16, a hoisting rope 12 drivingly connected to the hoisting motor 16, and a fixed sheave 14, and the hoisting motor 16 pulls the hoisting rope 12.

The movable pulley 18 is fixedly arranged on the outer box 19, and the hoisting rope 12 is in transmission connection with the movable pulley 18 to realize the purpose of pulling the outer box 19 to move up and down.

The traction mechanism 1 is used for achieving the effect of moving the equipment up and down, the traction motor 16 provides power to drive the traction rope 12 to move, and the traction rope 12 pulls the movable pulley 18 to move upwards, so that the effect of pulling the outer box 19 upwards is achieved.

The using method of the preassembly device for the elevator guide rail bracket comprises the following steps:

the method comprises the following steps: a preparation stage, wherein a fixed pulley 14 and a traction motor 16 are arranged at the top of a hoistway, one end of a traction rope 12 is arranged at the upper middle part of the hoistway, the traction rope 12 passes around a movable pulley 18 and the fixed pulley 14, the other end of the traction rope is arranged on the traction motor 16 and is used for dragging an outer box body 19, a power roller component 26 of a support roller mechanism 2 is extended or folded, rollers of the power roller component are attached to the wall surface, and the support mounting machine 47 and the automatic screwing machine 48 are ensured to store enough guide rail supports and screws;

step two: and a mounting plane grinding stage, grinding the plane needing to be provided with the guide rail bracket by a plane grinding machine 46, and adjusting the position of the plane grinding machine 46 on the plane of the hoistway by a longitudinal and transverse displacement mechanism 3.

Step three: in the drilling stage, drilling is carried out on the polished mounting plane through a drilling machine 45, and the drilling position is consistent with the positions of a pin hole and a screw hole of the rail mounting bracket;

step four: inserting the track support, namely inserting the prefabricated track support into a hole drilled on the mounting plane by using a support mounting machine 47;

step five: in the screw locking stage, screws are installed on the rail installation support through an automatic screw locking machine 48;

step six: and repeating the second step to the fifth step, and pre-assembling the next track support.
