Embodiment Construction

[0033] see Figures 1 to 9 Shown, the process equipment used in the method of the present invention comprises:

[0034] A frock base 12 (combined with Figure 9 As shown), it is used to install the chain box 1, the car arrester 2, the fixed guide rail 3, the control switch 4, the step positioner 5, the first transition guide rail 6 and the electrical control box 36 with PLC. The tooling base 12 is welded into a three-dimensional rectangular frame structure with square tubes, its left side inner end is welded into a ladder shape with square tubes, and an accommodating space 37 is reserved in the middle and lower part of the right side, and the electrical parts are effectively grounded.

[0035] Chain case 1 (combined with figure 2 Shown) is a rectangular box body welded by square tubes. The bottom plane of the box body is provided with a step shaft shelf 13 for neatly discharging pre-assembled step chains 14 and step shafts 15. The bottom of the chain case 1 is equipped wit...

Abstract

The invention discloses an escalator step chain and a step overall installation method. A tool is installed in a proper position; a hoist is used for driving a traction belt to pull the step chain to enter an advancing guide rail in an escalator truss along a fixed guide rail and a transitional guide rail, and the step chain and steps are assembled into a whole in the process; then, the step chain and the steps are distributed full in a back guide rail in the truss by using the steering of upper chain wheels of an escalator; and finally, corresponding components are removed. The invention also discloses a tool equipment used in the method, comprising a tool base, a chain box, a vehicle stopper, the fixed guide rail, a control switch, a step positioner, a first transitional guide rail, an electrical control box with PLC (programmable logic controller) and the like. The invention has the advantages of safety, reliability, time saving and labor saving in implementation, reduces operational danger and labor intensity, saves labor cost and operational time, and enhances working efficiency.

Description

technical field [0001] The invention relates to a method of installing an escalator step chain and steps in a factory. The invention also relates to a process plant for the method. Background technique [0002] For the installation of the current escalator step chain and steps, as long as the step shaft has been pre-assembled on the step chain, it is necessary to use the crane to lift the step chain to lay it on the inner guide rail of the escalator truss. After the step chain is connected to form a complete ring The steps can be loaded from the lower part or tail of the escalator only after it is in shape. At this time, if the escalator stands on the assembly frame, the construction personnel need to bend down to position and fasten the steps; if the escalator lies on the ground, the construction personnel need to stand on the inclined tail floor or squat on the same inclined middle truss angle steel Position and tighten the rungs. Regardless of the above installation me...
