[0011] 1. The utility model is provided with a guide component. This design brings about that when in use, the second steel wire rope drives the connecting seat to move downward through the operation of the stepping motor. By fixing the connecting seat and the ground, when the hoisting structure hoists the elevator accessories, the guide sleeves on both sides of the hoisting structure slide up and down outside the second steel wire rope, providing guidance for the movement of the hoisting structure, and avoiding swinging during the rising process of the hoisting structure.

[0012] 2. The utility model adopts this design. After the connecting seat moves to the top of the ground, it can be judged whether the connecting seat is horizontal by observing the level bubble. If the connecting seat is tilted, the screws on both sides are adjusted and rotated respectively so that there is a height difference between the two screws and the support seat, thereby achieving the effect of leveling the connecting seat, and then the fasteners are passed through the positioning holes to complete the fixation between the connecting seat and the ground.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0019] Example 1: Reference Figure 1-4 The utility model provides a hoisting device for elevator installation, including a hoisting machine body 100, the hoisting machine body 100 includes a bracket 110, a first steel wire rope 111 and a hoisting structure 112, the inner surface of the bracket 110 is fixedly installed with a guide assembly 200, the guide assembly 200 includes a mounting frame 210, the mounting frame 210 is fixedly installed on the inner surface of the bracket 110, a stepping motor 211 is fixedly installed on the top of the mounting frame 210, a second steel wire rope 212 is fixedly installed on the outer surface of the output end of the stepping motor 211, and the second steel wire rope 212 is wound around the outer surface of the output end of the stepping motor 211, and the second steel wire rope 212 is wound around the outer surface of the output end of the stepping motor 211. A connecting seat 213 is fixedly installed at the end of the second steel wire rope 212 away from the stepper motor 211, and a positioning hole 214 is opened at the top of the connecting seat 213. A guide sleeve 215 is fixedly installed on the outer surface of the second steel wire rope 212, and the guide sleeve 215 is connected to the lifting structure 112. There are two guide assemblies 200, and the two guide assemblies 200 are installed on the side where the two brackets 110 are close to each other.
