Problems solved by technology

[0003] In order to solve the problem that when adding a crane in the closed factory building, due to the limited space in the factory building, it is impossible to install the crane directly in the factory building with a crane and to avoid the impact of the installation of the crane on the existing production
The invention provides a high-altitude integral suspension and transposition construction method of a crown block, which not only solves the technical problem of installing a new crown block without affecting production, but also avoids the cumbersome procedures of the conventional method and the impact on production. And save the high shift fee of large cranes

Embodiment Construction

[0009] The construction method of crane transposition is described below in conjunction with specific embodiment, and construction method adopts following steps, as figure 1 Shown:

[0010] ①Use the electric hoist 1 on the line layer to hoist one end of the main beam of the suspended crane 7, set a pulley block 2 at the other end of the roof truss monorail beam 5 to hoist the other end of the suspended crane 7, and hoist the suspended crane 7 to the space between the two roof trusses space;

[0011] ② Pass the running crane 11 under the suspended crane 7 and run to the designed position;

[0012] ③The electric hoist 1 and the pulley block 2 slowly fall back to suspend the crane 7 to the rail surface.

[0013] ④ Restore the pulley of the crane that has been lowered, check the working condition of the crane, and put it into use if there is no abnormality. So far, the crane transposition work has been completed and the design layout requirements have been met.

Abstract

The invention relates to a construction method of high altitude suspension and transposition for the whole crown block, in particular to transposing the crown block which is arranged on the crown block rail by using the workshop spatial structure in the building. The steps adopted are that: (1) one end of the main beam of the suspended crown block (7) is hoisted by using the electric bottle hoist (1) on the line level, a pulley block (2) is arranged at the other end of the roof truss monorail beam (5), and the other end of the suspended crown block (7) is hoisted, the suspended crown block (7) is hoisted in the space between the two roof trusses; (2) the running crown block (11) runs through the beneath of the suspended crown block (7) to the designed position; (3) the suspended crown block (7) is slowly fallen back to the rail surface by using the electric bottle hoist (1) and the pulley block (2), the transposition of the crane is completed. The construction method has the advantages of changing the previous method of demolishing the roof firstly and then hoisting by using the big crane, achieving the goal of saving labor, time and money.

Description

technical field [0001] The invention relates to a method for installing a crane, and is especially suitable for a high-altitude integral suspension transposition construction method of a crane newly added in a closed factory building. Background technique [0002] At present, for the installation of new cranes between the cranes that have been put into production in closed workshops, the construction method of first removing the roof, and then using a large crane to hoist the components of the crane into place one by one and assemble them is generally adopted. This method affects the operation of the original crane, the workload of dismantling the factory building is large, and the cost of hoisting with a large crane is high. Contents of the invention [0003] In order to solve the problem that when adding a crane in the closed factory building, due to the space limitation in the factory building, it is impossible to install the crane directly in the factory building with ...
