Problems solved by technology

The problem with this kind of small gantry crane structure is that if the escalator has been put into use, the maintenance operation for the purpose of replacing the main drive needs to remove all the escalator structures above the main drive installation position in advance, so that the small gantry crane structure can be erected and developed. Space for main drive lift
The process of dismantling and installing the escalator structure is cumbersome, difficult to operate, loss of man-hours, and seriously slowing down maintenance and repair time

Embodiment 1

[0047] Such as Figure 1-9 As shown, the present embodiment provides a hoisting tool for the main drive of an escalator, which is composed of a rotating bracket 1 , a hoisting mechanism 2 , a base 3 , a rail frame 7 and an auxiliary mechanism 6 .

[0048]The lower truss 4 of the escalator extends to the outside of the end of the escalator, so that the length of the hoistway formed by the truss 4 is increased, which is convenient for matching the hoisting tooling of this embodiment. Before hoisting the main drive 5, it is necessary to disassemble the floor on the side of the escalator to expose the shaft formed by the truss 4, and install the auxiliary mechanism 6 in the shaft. The bracket 62 is fixed on the truss 4, and the telescopic screw 61 is set horizontally, one end of which is fixed on the bracket 62, and the other end is installed with a limit piece 63, and the main drive 5 is pushed through the limit clamp 63, so that the auxiliary mechanism 6 pushes the main drive ho...

Embodiment 2

[0057] Such as Figure 1-9 As shown, this embodiment provides an operation method for the main drive hoisting tool of the escalator, adopts the main drive hoisting tool of the escalator in Embodiment 1, and implements the following steps:

[0058] Step 1: In the preparation stage, the base 3 is installed on the bottom of the well, the guide rail frame 7 is installed on the ground at the edge of the well, the rotating bracket 1 extends into the well and is hinged to the base 3, the hoist 13 is fixed on the ground or on the guide rail frame 7, The electric chain hoist is installed on the roller 115 on the top of the rotating support 1 .

[0059] Step 2: During the hoisting stage, the hoist 13 puts the rope, at this time the main structure of the frame body 11 of the rotating bracket 1 tilts towards the direction of the main drive 5, until the electric chain hoist approaches the faucet of the escalator and stops, at this time, the position of the rotating bracket 1 is maintained ...

Abstract

The invention discloses an escalator main drive hoisting tool and an operation method. The escalator main drive hoisting tool comprises a rotating support, a hoisting mechanism and a base. The base is installed at the bottom of a truss extending part on the side of an escalator, the bottom of the rotating support is hinged to the base so that the rotating support can swing towards a main drive, and the hoisting mechanism is installed on the rotating support and used for hoisting the main drive. The hoisting mechanism hoists the main drive to enable the main drive to transversely move in a hoistway built by a truss through the swing motion of the rotating support, and then the main drive ascends and descends through the hoisting mechanism after reaching the upper truss extending part without barrier shielding. The detached main drive is firstly moved towards the side and then lifted to the ground height, an escalator structure above the main drive installation position is avoided, the detaching and installing steps are omitted, the operation process of replacing the main drive is simplified, and the maintenance construction efficiency of the escalator is improved.

Description

technical field [0001] The invention belongs to the technical field of escalator installation, and in particular relates to an escalator main drive hoisting tool and an operation method. Background technique [0002] Escalators are often installed in indoor places such as subways, shopping malls, and office buildings. The main drive is generally installed in the shaft built by the lower truss of the escalator structure, which is the core structure of the escalator. Because the weight of the main drive is very difficult to carry manually, and large hoisting equipment cannot enter the indoor place. Therefore, the installation / disassembly operation of the main drive of the escalator needs to be equipped with a compact and labor-saving hoisting tool. [0003] The existing hoisting tooling mainly adopts a small-sized gantry crane structure to be erected above the escalator truss, and the main drive is hoisted directly up and down. The problem with this kind of small gantry cran...
