Problems solved by technology

[0002] In the prior art, in the construction industry, scaffolding is usually used to lift the lifting brackets. Specifically, it is manually built up in groups. The order of construction is that each time a new group is erected on top of the previous group. The above-mentioned All processes are completed manually, which is not only labor-intensive, but also low-efficiency

Embodiment 1

[0030] Specific embodiment 1 of the four-screw lifting device of the present invention, as figure 1 and figure 2 Shown, comprise frame 16, four screw nut mechanisms, transmission mechanism, lifting drive unit, two lifting fork 19 and two lifting fork dislocation drive units. Compared with the prior art, the present invention can realize synchronous and fast lifting of the lifting bracket 23 through the lifting drive device, four screw nut mechanisms, transmission mechanism, two lifting swing rods 19 and two lifting swing rod dislocation drive devices. And disassembly, and the adopted four-screw nut mechanism rotates synchronously through the two-stage synchronous transmission mechanism in the transmission mechanism to achieve the purpose of synchronization, stability and high precision. sinking phenomenon. It has the characteristics of high lifting efficiency, stable and reliable work, and is convenient for large-scale application and popularization in the construction fiel...

Embodiment 2

[0049] The second specific embodiment of the four-screw lifting device of the present invention, the main technical solution of this embodiment is the same as that of embodiment 1, and the features not explained in this embodiment are explained in embodiment 1, and will not be repeated here to repeat. The difference between this embodiment and Embodiment 1 is that: the lifting swing rod 19 dislocation driving device is directly driven by the cylinder.

Abstract

The invention discloses a four-lead screw lifting device, comprising a frame, four lead screw nut mechanisms, a transmission mechanism, a lifting driver, two elevating swing rods and two elevating swing rod malposition drivers. Compared with prior art, the invention is able to lift and disassemble the lifting frame synchronously and rapidly through the lifting driver, the four lead screw nut mechanisms, the transmission mechanism, the two elevating swing rods and the two elevating swing rod malposition drivers. Furthermore, the four lead screw nut mechanisms adopted rotate synchronously through a secondary synchronous transmission mechanism to fulfill the purposes of synchronization, stability and high precision. The four lead screw nut mechanisms can descend and have self-locking function and is able to avoid sinkage during mechanical malfunction. The four-lead screw lifting device has the advantages of high lifting efficiency and stable and reliable work and is convenient to apply and popularize in a large area in the field of building as well.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a four-screw screw lifting device. Background technique [0002] In the prior art, in the construction industry, scaffolding is usually used to lift the lifting brackets. Specifically, it is manually built up in groups. The order of construction is that each time a new group is erected on top of the previous group. The above-mentioned All processes are completed manually, which not only has high labor intensity, but also has low work efficiency. [0003] Therefore, in order to solve the above problems, it is particularly important to provide a technology of a four-screw lifting device that has high lifting efficiency, stable and reliable operation, and is convenient for large-area application and popularization in the construction field. Contents of the invention [0004] The object of the present invention is to avoid the disadvantages of the prior art and prov...
