Description

Technical Field

[0001] The utility model belongs to the technical field of building construction machines, in particular to a guide rail and oil cylinder self-climbing lifting device for a building construction machine. Background Art

[0002] In high-rise buildings, the use of building cranes is a common phenomenon; the climbing process of the building crane construction platform is divided into two steps: lifting and lifting.

[0003] At present, the climbing process of the construction platform of a building construction machine usually only involves the process of jacking up, and the jacking cylinder and climbing boots are manually circulated to the next floor, which results in low work efficiency. In this regard, the utility model with the publication number CN217897231U discloses an overall climbing device for the construction platform of a building construction machine. Although the climbing device solves the problem of climbing up and falling back down, the corresponding lock tongue position adopts a power hydraulic cylinder, and the locking needs to be controlled based on the form of a power hydraulic cylinder, and the structure and control are relatively complicated. In addition, the limit between the guide rail designed on the structure only adopts a roller set at one end. Once the roller is worn out after long-term use, it is easy to cause unevenness and incoordination between the upper and lower parts, and the wear resistance and efficiency of use are relatively low. Therefore, this technical solution proposes a lifting device with self-climbing guide rails and oil cylinders for building construction machines. Utility Model Content

[0004] The utility model provides a lifting device for the guide rail and oil cylinder of a building construction machine, which is composed of an upper hoisting machine and a lower hoisting machine located at the upper and lower ends of the jacking oil cylinder. The upper hoisting machine includes two groups of open limit grooves that are symmetrically arranged on the left and right and engage with the side parts of the climbing guide rails, and a load-bearing tongue block that is corresponding to the positioning hole on the surface of the climbing guide rail and is rotatably installed between the two mounting plates through a reversing pin shaft. One end of the load-bearing tongue block is connected with a bolt on a reversing shaft sleeve, and the other end is connected with a support on a lifting frame body. When the load-bearing tongue is against the guide rail, the tension spring ensures that the load-bearing tongue does not deflect; the guide rail or the hoist is supported by changing the direction of the load-bearing tongue of the hoist; the direction of the load-bearing tongue in the hoist is changed by the reversing shaft in the hoist to realize the function conversion of the jacking guide rail and the lifting oil cylinder; when the guide rail needs to be jacked, the handle on the reversing shaft is turned to make the load-bearing blocks in the upper and lower hoists uniformly support the guide rail upward, and the load-bearing tongue supports the upper end of the ladder step of the guide rail; then When the lift is lifted, the hydraulic cylinder is retracted to lift the lower hoist, and the load-bearing tongue of the lower hoist is pressed against the lower end of the guide rail ladder step to complete the lifting of the upper hoist; then, the connecting pin shaft between the lower hoist and the hanging shoe is removed, the hydraulic system is started, the oil cylinder is retracted, the lower hoist is lifted, and the load-bearing tongue of the lower hoist is pressed against the lower end of the guide rail ladder step to complete the lifting of the lower hoist; the upper hoist, the lower hoist and the load-bearing tongue block have high structural strength; compared with the prior art, the wear resistance, service life and stability between the guide rail and the lower hoist are better, and the use efficiency is higher; in summary, the problems in the background technology are solved.
