Embodiment Construction

[0026] The installation method of the bridge crane in the factory building under the closed environment provided by the present invention is to utilize a single machine (one truck crane) to hoist all the main and auxiliary beams, and the main trolley utilizes two truck cranes to lift and lift the installation method, and the beam crane method is used to install the bridge crane Methods. Specifically, follow the steps below:

[0027] Step 1: Construction preparation:

[0028] ① Carry out a second retest of the driving beam track of the original factory building. After long-term operation and foundation settlement, the driving beam track of the technically transformed factory building must be retested before installation to meet the driving installation requirements. Re-test requirements are gauge deviation ±2mm, height difference 1mm;

[0029] ② Clean up the hoisting ground site to ensure the storage of equipment after entering the site and the station and hoisting of large-s...

Abstract

The invention discloses an installing method for a bridge crane in an enclosed environment workshop, and belongs to the technical field of hoisting device installing. The installing method includes the steps that a crane beam rail in the original workshop is retested, and a main beam supporting frame used for containing and assembling a main beam is manufactured; devices on the main beam are assembled through an auxiliary crane, the main beam is hoisted through a large crane, after the main beam is installed, end beams of the main beam are not connected, two large cranes are located on the two sides of the end beams, and hoisting lugs of two truck-mounted cranes are arranged at the ends of a main trolley; after the main trolley is evenly hoisted to be in place, assembling is carried out; and installing of the main beam bridge crane is completed. According to the installing method, the requirement for a site in the workshop is not high, the roof of the workshop does not need to be dismantled, the large crane is not used, ground assembling is rapid, hoisting is once achieved, the working efficiency is high, and the upper-air operational quantity is small; and the installing method has the beneficial effects that the practical hoisting time is short, the practicability is high, and the like.

Description

technical field [0001] The invention belongs to the technical field of hoisting equipment installation, and in particular relates to a bridge crane assembly method in a closed environment factory building, and a single-machine and double-machine lifting installation method. Background technique [0002] At present, the patent documents on the installation of bridge cranes mainly include: "Crane Constant Lifting Force Pre-adjustment and Leveling Lifting Method" (CN101734556A), which mainly refers to the horizontal plane of the center of gravity of the heavy object and the surface of the heavy object when it is hoisted in place. Set up three lifting points at the intersection; at the beginning of hoisting, first adjust the plane of the lifting point to level, and then lift or turn synchronously under the vertical hoisting of the crane until the heavy object is lifted in place; The method and the application of the method" (CN102267664B), it is mainly to set the lifting point o...
