Embodiment 1

[0039] Such as figure 1 , figure 2 As shown, the folding shelter lifting device in this embodiment includes a cabin body 1 and a lifting device 2 arranged on the cabin body 1. The lifting device 2 is symmetrically arranged on the left and right sides of the cabin body 1, and can be expanded outwards. The whole cabin body 1 is supported. In order to further improve the stability of the cabin body 1, two sets of lifting devices 2 are arranged at the front and rear of the cabin body 1, that is, a lifting device 2 is arranged around the cabin body 1 to stably support the cabin body 1 .

[0040]The lifting device 2 can be telescopically adjusted to change the length of the lifting device 2 itself. In addition, there are various structures that can realize the adjustment of the length of the lifting device 2 itself, such as linear transmission mechanisms such as a gear 9 rack mechanism, a screw rod 6 nut mechanism, or a linear drive device such as a cylinder, etc., which will no...

Embodiment 2

[0045] Such as figure 1 , figure 2 As shown, in the folding shelter lifting device of this embodiment, a driving device is arranged between the cabin body 1 and the lifting device 2, and the driving device drives the cabin body 1 and the lifting device 2 to move relative to each other.

[0046] The driving device described in this embodiment can directly act between the cabin body 1 and the lifting device 2, for example: a cylinder is set between the cabin body 1 and the lifting device 2, and the two ends of the cylinder are respectively connected to the cabin body 1, The lifting device 2 is hinged so as to adjust the expansion of the cabin body 1 and the lifting device 2 .

[0047] The driving device described in this embodiment can also be a device that is arranged between the cabin body 1 and the connecting rod 3, and drives the relative movement between the lifting device 2 and the cabin body 1 by rotating the connecting rod 3 around the hinge. For example: the cabin bo...

Embodiment 3

[0050] Such as figure 1 , figure 2 As shown, in the folding shelter lifting device of the present embodiment, the driving device is the hoist 4, and the hoist 4 is connected with a rope 5, and one end of the rope 5 is fixedly connected with the reel of the hoist 4, and the other end of the rope 5 is connected with the lifting device 2. To connect, by rotating the reel, the rope 5 wound on the reel generates traction, and driven by the rope 5, the lifting device 2 and the cabin body 1 move relative to each other in the transverse direction.

[0051] Please refer to Embodiment 2 for other structures.

Abstract

The present invention relates to a foldable square cabin lifting device, comprising a cabin body and lifting device arranged on the cabin body. At least two side links are disposed between the cabin body and the lifting devices, and both ends of each side link are respectively hinged to the cabin body and the lifting devices, the cabin body, the lifting devices and the side links forming a parallelogram mechanism moving in a vertical plane; the lifting devices are driven to move in the vertical plane by the side links through connecting the cabin body and the lifting device with at least two side links, the cabin acting as a rack, two side links acting as cranks and the lifting devices acting as a rocker; the lifting devices perform synchronous motion along a horizontal direction and a vertical direction in the vertical plane, realizing synchronous operation of outward expansion and downward transferring along vertical direction of the lifting device, which is different from the prior art, wherein a lifting device need to carry out hinge-type unfolding along a hinge before the downward transferring and then to adjust the length of the lifting device along a vertical direction to achieve a longitudinal unfolding mode: therefore, the device provided in the present invention is advantaged in convenient operation as well as fast loading and unloading.

Description

technical field [0001] The invention relates to a hoisting device for a shelter, in particular to a folding hoisting device for a shelter that can be retracted laterally. Background technique [0002] The structure of the shelter is similar to that of a container. It is usually welded by metal plates. Usually, the shelter is equipped with a vehicle to carry it to the desired place. The standard is also formulated with reference to the container standard. Compared with the container, it has Higher maneuverability. [0003] Most of the existing shelters are loaded or unloaded by direct lifting, which is not only cumbersome and time-consuming, but also needs to rely on lifting equipment to complete the loading and unloading operations. [0004] Please refer to the Chinese utility model patent "Square cabin container lifting and unloading mobile walking device" with application number 200420109260.4, and the Chinese utility model patent "Square cabin lifting device" with appli...
