Novel method for mounting chain-and-grid conveyer through pre-combination method

Abstract

The invention discloses a novel method for mounting a chain-and-grid conveyer through the pre-combination method. The method is characterized by including the following steps that first, seven-chain combinations are well assembled; second, the seven-chain combinations are conveyed to the site in batches, and upward supporting shafts are installed in a one-to-one mode; third, all the combinations on the upward supporting shafts are connected together in a one-to-one mode; fourth, chain-and-grid devices connected in a qualified mode are moved forward so that the room can be given to connection in the next step; fifth, after several sections of chain-and-grid devices at the positions of a first wheel and a tail wheel are well combined during installation, a winch is used for bothway fixing and matching, the chain-and-grid devices slide in place slowly and then are closed, and the chain-and-grid devices of the upward supporting shafts are moved to the positions of the first wheel and the tail wheel for connection; and sixth, the chain-and-grid conveyer is well mounted. By the adoption of the method, reinforcing steel bars are distributed according to the structural style and stress state, and the using quantity of the reinforcing steel bars is decreased under the premise that the stress and spacing requirements for the reinforcing steel bars in design are met to the maximum degree; and moreover, the blanking mode of the reinforcing steel bars is single, the number of varieties and specifications is small, workers can understand easily in construction, and operation is easy.

Description

technical field [0001] The invention relates to a new method for installing a chain grate by a pre-combination method. Background technique [0002] According to the original construction method of the chain grate machine, after the upper and lower support systems and the head and tail wheels are installed, a platform is set up at the high-altitude idler roller position for assembly, and the assembled section is dragged away by winch, and then the next section is assembled on this platform , until the chain grate device of the entire upper idler is covered, then another winch is used to seal it, and then the lower idler is passed around the head wheel and the installation continues until the lower idler is covered. [0003] In the existing construction method, the installation is all completed at high altitude, which has great potential safety hazards, difficult operation, low work efficiency, and difficulty in guaranteeing the construction period. It is inconvenient for hi...

Problems solved by technology

[0003] The existing construction method, the installation is all completed at high altitude, the operation safety hazard is great, the operation is difficult, the work efficiency is low, and the construction period is difficult to guarantee

It is inconvenient for high-altitude workers to operate, the accuracy is not easy to guarantee, and the on-site labor intensity is high

Large-scale hoisting equipment is required to cooperate on site all the time, and two large hoists, one to pull the chain grate device forward and one to control the position of the chain grate device to prevent movement deviation, the construction site invests a lot
