Problems solved by technology

The current common practice is to set up a suspended temporary simple work platform or a two-story suspended scaffold at the top of the hoistway, and use the platform or scaffold to help the counterweight frame enter the hoistway to complete its position. After installation, it needs to be dismantled. Simple platforms or scaffolding, this method not only increases the cost of materials but also increases the workload, and there are certain safety hazards

Embodiment

[0023] A method for installing an elevator counterweight frame, the steps of which are as follows Figure 1-9 as shown in:

[0024] see figure 1 , hang the manual hoist 16 on the maintenance hook 14 of the elevator machine room, drill a φ18mm through hole 13 on the ground floor of the elevator machine room, that is, the top floor 12 of the shaft, and the vertical projection of the through hole 13 falls on the elevator hall In the middle of the doorway, it is about 300-400mm away from the front wall of the well in the well. Put down a counterweight hoisting steel wire rope 1 from through hole 13, one end is hung on the suspension hook of manual hoist 16, and the other end passes top floor slab 12 and is put to top floor door 11 outsides. The counterweight frame 2 is moved from the outer side of the top floor to the accessory position of the landing door 11;

[0025] see figure 2 , install the traction wire rope 3: put down the traction wire rope 3 with a taper sleeve insta...

Abstract

The invention discloses an installation method of a counter-weight frame of an elevator, comprising the following steps of: arranging a lifting mechanism on an overhauling lifting hook of an elevator machine room, and drilling a through hole in a top-layer floorslab of a hoistway; hanging a counter-weight lifting steel wire used for lifting the counter-weight frame on the lifting mechanism, and placing through the through hole; completing the installation of a dragging steel wire near a top-layer door by the counter-weight frame; controlling the lifting mechanism to lift the counter-weight frame to complete the installation and the fixation of a counter-weight block positioned on the counter-weight frame and the connection and the fixation of the dragging steel wire positioned at a car side; controlling the lifting mechanism to lift the counter-weight frame into the hoistway, and then releasing the lifting mechanism so that the counter-weight frame moves under the action of gravity inthe hoistway till the counter-weight frame moves in position; and removing the fixation of the counter-weight lifting steel wire on the lifting mechanism after the dragging steel wire is completely tensed under stress. The invention can realize the counter-weight frame top-layer installation without an auxiliary operation platform or a scaffold, has convenient construction, safety and reliability, effectively reduces the operation cost, and prevents safety risks.

Description

technical field [0001] The invention relates to the field of elevator installation engineering, in particular to an installation method of an elevator counterweight frame. Background technique [0002] There are two main ways to install elevators, one is the traditional and widely used installation method using scaffolding, and the other is the installation method without scaffolding that has gradually begun to be used. When involving the installation of the elevator counterweight frame, due to the need to utilize the car frame as the work platform to carry out the installation of shaft components such as guide rails, the shaft components such as guide rails must be installed step by step from bottom to top. Therefore, the car frame needs to be installed on the first floor as a working platform, and the counterweight frame needs to be installed on the top floor into the hoistway, and the counterweight frame is usually located on the side of the hoistway away from the car doo...
