Problems solved by technology

[0007] 1. Use linear transmission mechanisms such as worm gear mechanism, screw nut pair, ball screw nut pair, etc. to drive the lifting mechanism to perform vertical lifting, which is not only inconvenient for production and manufacturing, but also has a large amount of processing and high cost, and the lifting speed is slow and the efficiency is low. ;
[0008] 2. In harsh environments such as wind and sand, it is easy to get stuck in the sand and cause failure, and the safety and reliability are poor;
[0009] 3. When the lifting device supports the shelter, the whole shelter is easy to tilt due to the uneven ground, and it is difficult for the above-mentioned lifting mechanism to adjust the whole shelter to the level, with low efficiency and poor precision;
[0010] 4. There is no self-locking mechanism, and there is a risk of accidental landing of the cabin due to misoperation by operators or even children

Embodiment 1

[0042] Such as figure 1 As shown, the shelter lifting mechanism in this embodiment includes a sleeve 1, and a movable support rod 2 sleeved inside the sleeve 1, wherein the sleeve 1 is used as a reference component for synchronous lifting with the shelter in the lifting mechanism, and the movable support Rod 2 is used to contact the ground and prop up the entire shelter lifting mechanism. There is a gap between the movable support rod 2 and the inner wall of the sleeve 1, and a driving device is arranged between the movable support rod 2 and the sleeve 1. It is used to drive the movable support rod 2 to move relative to the sleeve 1. More specifically, the driving device is used to drive the movable support rod 2 to be inserted into the sleeve 1 or protrude from the bottom of the sleeve 1, so as to realize the overall lifting mechanism. The change of the height, the sleeve 1 is provided with a first sprocket 3a and a second sprocket 3b, wherein the first sprocket 3a is located...

Embodiment 2

[0045] Such as figure 1 As shown, the shelter lifting mechanism of this embodiment is a further improvement of Embodiment 1. The driving device is a drive sprocket 5 provided with a power source, and the chain 4 is closed to form a chain ring. The chain ring is connected to the first sprocket 3a, the second chain The two sprockets 3b and the drive sprocket 5 are matched and connected and pre-tensioned, that is, the chain ring is surrounded and tensioned between the first sprocket 3a and the second sprocket 3b, through the normal rotation of the drive sprocket 5 and Reversed to realize the rise or fall of the part of the chain 4 located inside the sleeve 1 and used to drive the movable strut 2 up and down, thereby driving the movable strut 2 up and down. In this way, the tensioned chain 4 has a large driving torque, which makes it easier to lift and operate, and when the chain 4 is closed and rotated, the operation stroke is not limited by the length of the chain 4, and the str...

Embodiment 3

[0048] Such as figure 1 As shown, the shelter lifting mechanism of this embodiment is a further improvement of Embodiment 2, the first sprocket 3a is arranged on the top of the sleeve 1, the second sprocket 3b is arranged below the first sprocket 3a, On the outer wall of the sleeve 1, a chain inlet 6 for the chain 4 to penetrate is provided on the side wall of the sleeve 1. After the chain 4 bypasses the second sprocket 3b, it passes through the chain inlet 6 into the sleeve 1, and after bypassing the first sprocket 3a, go out from the opening at the top of the sleeve 1 to the outside of the sleeve 1, and cooperate with the driving sprocket 5 to form a chain ring. In this way, While realizing the lifting movable support rod 2, it is beneficial to the structural arrangement, the chains 4 are respectively arranged inside the sleeve 1, and the outer two sides are not easy to be entangled and interfere with each other.

[0049] Please refer to Embodiment 2 for other structures. ...

Abstract

The invention discloses a shelter lifting mechanism which comprises a movable supporting rod arranged inside a sleeve and a driving device for driving the movable supporting rod and the sleeve to move relatively. The sleeve is provided with a first chain wheel and a second chain wheel. The first chain wheel is arranged above the second chain wheel, a chain is connected between the first chain wheel and the second chain wheel in matching mode, the chain is arranged inside the sleeve, the driving device drives the chain to lift inside the sleeve, and the chain drives the movable supporting rod to lift inside the sleeve. The chain is adopted for driving the movable supporting rod to lift relatively in the sleeve, transmission speed ratio is large, lifting speed is high, the efficiency is high, the cost is low, manufacture and installing are convenient, and the shelter lifting mechanism is especially suitable for severe environments such as a sandy and windy environment and safe and reliable.

Description

technical field [0001] The invention relates to a lifting mechanism, in particular to a shelter lifting mechanism for unloading a shelter from a vehicle or loading it into a vehicle. 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 operation. To solve the above problems, lifting equipment is usually installed around the shelter device, and adjust the height of the shelter from the ground with the help of the lifting device to realize the self-elevating of the shelter, and ...
