Embodiment 1

[0044] Such as Figure 3 to Figure 8 As shown, the screw jack 25 includes a fixed base, a platform that rotates around the fixed base, a motor 23 that drives the platform to rotate, a storage box 6 installed on the platform, a spring flat belt 1 stored in the storage box 6, Installed in the fixed base and cooperate with the spring flat belt 1 to form the toothed spring bar 2 of the spiral cylinder. The belt track lifting mechanism is installed on the platform to restrain the toothed spring bar 2 from lifting or shrinking movement 3. It is used for The track guide frame 4 that makes the spring flat belt 1 and the toothed spring bar 2 engage. The motor 25 drives the platform to rotate, and then drives the belt track lifting mechanism 3 to rotate, and the belt track lifting mechanism 3 makes the toothed spring bar 2 rise and fall under the guidance of the belt track lifting mechanism 3, and simultaneously pulls the spring flat belt 1 to spirally climb , Under the pushing action ...

Abstract

The invention relates to a spiral lifting crane system. The spiral lifting crane system comprises a bottom platform fixed to the ground, a spiral lifting machine mounted on the bottom platform, a tower crane base mounted at the top end of the spiral lifting machine, a rotating platform mounted on the tower crane base and a telescopic arm type crane mounted on the rotating platform. The spiral lifting crane system further comprises a controller for controlling the spiral lifting machine to rotate. The spiral lifting crane system has the beneficial effects that the structural design is reasonable, the load is large, the telescopic performance is super-high, and the relative lifting height is high; and the operable area is enlarged greatly, the working efficiency is improved more effectively, and the cost is lowered. According to the spiral lifting crane system, the rising and falling of the telescopic arm type crane are achieved by the adoption of the combination of a spiral lifting mechanism and a bamboo joint type lifting supporting bracket, the space structure is compact, the lifting force cannot become small suddenly when the lifting height is increased, and the stability and the safety performance are higher.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a spiral lifting crane system. Background technique [0002] Lifting equipment plays an important role in many engineering constructions, realizing the lifting and transportation of heavy objects, thereby improving construction efficiency. However, most of the existing lifting equipment is tower cranes, which are suitable for large-scale heavy object transportation. However, such tower cranes are large in size and are all fixed. The traditional lifting equipment in the overall space cannot be satisfied. Therefore, a kind of new hoisting equipment is urgently needed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a spiral lifting crane system. [0004] The technical problem to be solved by the present invention adopts the following technical solutions to realize: [0005] A spiral lifting crane system, i...
