Problems solved by technology

[0005]The purpose of the present invention is to overcome the need for manual operation of the pole locking and unlocking of the existing shelter lifting device, which is inconvenient to operate and affects the efficiency of the shelter lifting, and is very difficult It is difficult to realize the complete automatic operation of the entire lifting process and the technical problem of low operating efficiency. An electric lifting mechanism is provided, which can realize the automatic operation of the entire lifting operation of the electronically controlled shelter, and does not need to manually adjust the locking and unlocking of the pole, which greatly improves the operation. efficiency

Embodiment 1

[0040] Such as Figure 1 to Figure 4 As shown, the electric lifting mechanism of this embodiment includes a transmission chain 3 connected to the shelter support 4 and the grounding leg 1, and the transmission chain 3 is driven to rotate by an electric drive device to drive the shelter support 4 and the grounding support. The outrigger inner tube 2 in the outrigger 1 rises and falls synchronously; at least two connecting struts are set between the shelter support 4 and the grounding outrigger 1. In this embodiment, two connecting struts are set, which are respectively the upper The connecting pole 7 and the lower connecting pole 6 are provided with a locking device on the upper connecting pole 7, and a forced opening and closing mechanism is provided corresponding to the locking device, so that when the shelter 5 descends, the locking device automatically locks, and when the shelter 5 When rising, the locking device is automatically unlocked; or as required, when the shelter 5...

Embodiment 2

[0052] Such as Figure 1 to Figure 4 As shown, according to the electric lifting mechanism of Embodiment 1, on the basis of Embodiment 1, the upper end and the lower end of the leg inner tube 2 are all set as wedge-shaped surfaces in this embodiment, which are upper wedge-shaped surface 21 and lower wedge-shaped surface 22 respectively.

[0053] Further, such as figure 2 As shown, the lower end of the telescopic rod 8 is connected with a hinge plate 11, one end of the hinge plate 11 is hinged with the end of the telescopic rod 8, and the other end is connected with a roller device 10, and the middle part of the hinge plate 11 is hinged with the ground leg. The roller device 10 is arranged corresponding to the lower wedge-shaped surface 22 . So that when the shelter is lowered, that is, when the leg inner tube 2 is lowered, the lower wedge-shaped surface 21 contacts the roller device at the end of the hinge plate, so that the end of the hinge plate with the roller device rota...

Embodiment 3

[0055] Such as Figure 5 to Figure 7 As shown, according to the electric lifting mechanism described in embodiment 1 or embodiment 2, the electric lifting mechanism also includes a tilting mechanism arranged on the shelter 5, one end of the tilting mechanism is hinged on the shelter 5, and the other end is connected to the shelter 5. The shelter supports 4 are connected, and the tilting mechanism is provided with a driving device that makes its axis tilt, so that the supporting axis of the shelter 5 is inclined outward relative to the vertical direction.

[0056] The shelter tilting mechanism set on the electric lifting mechanism, after the shelter rises to a certain position, the support axis of the shelter is tilted outward relative to the vertical direction through the tilting mechanism, the support is stable, and the shelter is not easy to overturn. Then, the direction of the supporting axis of the shelter is offset from the vertical direction, and the shaft supporting the...

Abstract

The invention discloses a square cabin lifting device and discloses an electric elevating mechanism. The electric elevating mechanism comprises a transmission chain connected with a square cabin support and a grounding landing leg, wherein the transmission chain is driven through an electric drive device to rotate; the square cabin support and an inner pipe of a landing leg in the grounding landing leg are driven to synchronously ascend and descend; and a forced opening and closing mechanism is also arranged on a connecting support rod between the square cabin support and the grounding landing leg, so that automatic locking or unlocking can be achieved by a locking device and a locking hole when a square cabin ascends or descends. According to the electric elevating mechanism, automatic operation of the whole elevating operation of the square cabin can be achieved and locking and unlocking of the support rod do not need to be manually adjusted, so that the operation efficiency is greatly improved.

Description

technical field [0001] The invention relates to a shelter lifting device, in particular to an electric lifting mechanism. Background technique [0002] The structure of the shelter is similar to that of a container, usually welded by metal sheets, and the shelter is usually equipped with a vehicle, usually a pickup truck, which is transported to the required place by the vehicle, and its standard is also formulated with reference to the container standard. Compared with containers, shelters have higher maneuverability, and using the space of shelters to configure various items and equipment can provide reliable guarantee for field rescue and other operations. [0003] However, the weight of the shelter equipped with equipment and objects is relatively heavy. To realize loading or unloading between the shelter and the loading vehicle, it is generally operated by manually opening the support legs for manual or electric lifting, direct lifting, and dragging. Such a shelter loa...
