AI Technical Summary

Problems solved by technology

However, it is difficult to arrange the tower cranes of this type of building. If the tower cranes are arranged beside the tower, some buildings on the podium cannot be covered; The height of the building is relatively short, and the problem of installation and attachment cannot be solved; it is often necessary to arrange the tower crane in the building plane of the podium and close to the side of the tower, and at the same time solve the coverage of the tower crane and the attachment of the tower crane. Large truck crane
When there is a basement next to the podium, the roof of the basement needs to be reinforced when a large truck crane enters the construction site, resulting in increased demolition costs

Embodiment 1

[0026] Such as figure 1 , figure 2 , Figure 4 , Figure 5 As shown, a simple detachable and fixed gantry lifting device includes a counterweight arm 1, four gantry columns 2 are symmetrically fixedly connected to the upper surface of the counterweight arm 1, and two opposite gantry columns 2 The tops of the gantry beams 3 are fixedly connected with a gantry beam 3, the upper surface of the gantry beam 3 is fixedly connected with a longitudinal beam 4, the longitudinal beam 4 is movably connected with lifting lugs 5, and the lifting lugs 5 are connected with long-chain chain hoists 7. The heavy arm 1 is loaded with several counterweights 6, and the counterweights 6 are equipped with supporting components, the counterweights 8 are suspended on the counterweight arm 1 through the supporting components, and the counterweights 6 are also provided with a The connecting hole 8 to which the chain hoist 7 is connected. Use the long-chain chain hoist 7 to lift the counterweight 6,...

Embodiment 2

[0030] Such as figure 2 and image 3 As shown, in a further preferred solution on the basis of Embodiment 1, a braking structure is provided on the lifting lug 5, and the braking structure includes a hub 51, a locking rod 52, an adjusting rod 53 and a positioning sleeve 54, and the hub 51 is provided with two and They are all fixedly installed on the side of the lifting lug 5 opposite to the upper surface of the longitudinal beam 4. The two hubs 51 are connected as a whole through the connecting shaft. The end away from the hub 51 is rotatably connected to the connecting rod, and the end of the connecting rod away from the locking rod 52 is rotatably connected to the adjusting rod 53 , and the end of the adjusting rod 53 away from the connecting rod freely penetrates the lifting ear 5 and extends to the top of the lifting ear 5 . The positioning sleeve 54 is fixedly arranged on the lifting lug 5 and is covered on the outside of the adjusting rod 53. The top of the positionin...

Embodiment 3

[0032] A method for dismantling a simple detachable and fixed gantry lifting device, which particularly includes the following steps:

[0033]S1. By adjusting the adjusting nut 55, the adjusting rod 53 moves up to drive the locking rod to move to the center of the connecting shaft, unlock the hub 51, push the lifting lug 5 to the top of the weight plate 6, and pass through the hook of the long-chain chain hoist 7 Lift the counterweights 6 one by one, so that the support rod 62 on the counterweight 6 is separated from the positioning groove 12 on the positioning piece 11, and then slowly push the lifting lug 5, and the counterweight 6 is under the action of the guide wheel 63 and the return spring 61. Next, the counterweight arm 1 will move synchronously until all the counterweights 6 are unloaded on the roof of the podium, and all the counterweights 6 are removed by horizontal transport equipment;

[0034] S2. When the truck crane moves to the point where the center of the boo...

Abstract

The invention discloses simple, detachable and fixed gantry hoisting equipment and a dismantling method, and belongs to the technical field of tower crane dismantling equipment at podium buildings. The gantry hoisting equipment is provided with counterweight arms, gantry stand columns, a gantry beam, a carling, a lifting lug, a counterweight piece, a long-chain chain block and a supporting component, wherein the lifting lug is movably arranged on the carling, the counterweight piece is lifted through the long-chain chain block to enable the counterweight piece to freely move on the counterweight arm, the counterweight piece is moved to a roof of the podium building through the movable lifting lug, and then is conveyed through transportation equipment; and finally, a cargo boom and the counterweight arms 1 are dismantled; therefore, the dismantling efficiency is greatly improved, and the construction cost is saved.

Description

technical field [0001] The invention belongs to the technical field of dismantling equipment for tower cranes at podiums, and in particular relates to equipment and methods for dismantling large and medium-sized tower cranes in podiums of high-rise buildings. Background technique [0002] Due to the development of the city, there are more and more high-rise buildings, and large complexes such as hotels and shopping malls have gradually entered the city. Many large complexes such as hotels and shopping malls have a structure of towers and podiums. Multi-storey buildings; the emergence of this type of structure can meet the fire protection code requirements of multi-storey buildings and maximize the commercialization benefits of podium buildings with large spaces. It not only meets the functions of commercial retail, entertainment, large-scale catering and entertainment, but also saves Cultivated land beautifies the city and increases its functions. [0003] During the struct...
