[0001] The utility model belongs to portable building product technical field, concretely relates to a large gradient topography self -adaptation portable house overhead mechanism. BACKGROUND
[0002] The traditional movable folding house is limited by the jacking stroke height of the bottom portable foundation when being built on uneven terrain, especially in large slope or complex terrain area, not only the erection difficulty is big, but also the stability of the structure is difficult to guarantee. The existing overhead device such as shear type jack is widely used, but its jacking stroke is limited, generally in 300-400mm, and it is generally only applicable to the site with gentle slope (within about 3°). When facing the terrain with slope more than 3°, hydraulic jack needs to be used to increase the jacking height, which not only increases the cost, but also is not convenient for carrying and batch application due to the heavy weight of hydraulic jack equipment, and the hydraulic jack cannot be applied to low temperature environment (for example, high altitude low temperature environment) because the hydraulic oil will freeze at low temperature. With the increasing demand of movable and portable folding house, it is an urgent technical problem to provide an overhead mechanism which can adapt to complex terrain and is convenient to carry. SUMMARY

[0005] A large gradient topography self -adaptation portable house overhead mechanism, including shear type jack, backing plate, multiple standardization pad and connecting mounting plate;
[0006] The connecting mounting plate is used to be installed on the top of the shear type jack, and the shear type jack top supports the folding house through the connecting mounting plate;
[0007] Each standardization pad has a set height, and the standardization pad is used to support the bottom of the shear type jack to expand the jacking stroke of the shear type jack to the folding house;

Moreover, the standardized cushion blocks can be replaced with each other, and the number can be flexibly increased or decreased according to the terrain slope requirement, so as to realize wide adaptation to the slope change. The cushion plate increases the contact area with the ground, can disperse the pressure, and improve the stability and adaptability on complex terrain. The scissors jack supports the foldable house through the connecting mounting plate, which ensures the reliability of the support. At the same time, it is suitable for a wide range of regions, and can be used in general climate conditions, and can also be used in plateau areas and extremely low temperature environments in winter in cold regions.
[0020] 2. The length of the base of the scissors jack is increased to be equal to the length of the standardized cushion block, which enables the standardized cushion block to provide more reliable support for the scissors jack.
[0021] 3. The standardized cushion block is in a cavity structure, so that the weight of the standardized cushion block can be reduced, the weight reduction purpose is achieved, and transportation is facilitated.
[0022] 4. The cushion plate is provided with a through hole for penetrating the anchoring device, so that the overhead mechanism can be more firmly fixed on the ground through the anchoring device, especially suitable for soft or unstable ground conditions, and the safety of the overhead mechanism is enhanced.
[0023] 5. The cushion plate is designed as a replaceable laminated structure, and the hardness of each layer is different. In this way, the user can flexibly replace the cushion plate layer according to the hardness and stability requirements of the ground, so as to achieve the best ground adaptability and shock absorption effect.
[0024] 6. The bottom of the cushion plate is provided with a groove or a convex point for increasing the friction to improve the anti-skid performance of the overhead mechanism on an inclined or smooth ground, and the stability of the house is ensured.
[0025] 7. The level is arranged on the connecting mounting plate, so that the level can be used as a reference when adjusting the number of standardized cushion blocks or adjusting the lifting height of the scissor jack. That is, when the connecting mounting plate is in a horizontal state as shown by the level, it indicates that the support part has been adjusted to a horizontal state, and the influence of the slope has been eliminated. Therefore, it is very convenient to adjust the number of standardized cushion blocks or the lifting height of the scissor jack. BRIEF DESCRIPTION OF DRAWINGS

[0030] The present application will be described in detail below in combination with the drawings and examples.
[0031] Referring to Figs. 1-3 , a large-slope-terrain self-adaptive portable house overhead mechanism includes a scissor jack 1, a cushion plate 3, multiple standardized cushion blocks 2, and a connecting mounting plate 5, wherein:
[0032] The connecting mounting plate 5 is used for mounting on the top of the scissor jack 1, and the top of the scissor jack 1 supports the folding house through the connecting mounting plate 5; each standardized cushion block 2 has a set height, and the standardized cushion block 2 is used for supporting at the bottom of the scissor jack 1 to expand the jacking stroke of the scissor jack 1 on the folding house; the cross-sectional area of the cushion plate 3 is greater than that of the standardized cushion block 2, and the cushion plate 3 is used for supporting at the bottom of the standardized cushion block 2 to increase the contact area with the ground; the large slope is 3°~5°. It should be pointed out that the large slope terrain self-adaptive portable house overhead mechanism in the embodiment is not limited to be applicable to only the large slope terrain, but also applicable to the terrain with a slope of 3°~5° in addition to the terrain with a slope of less than 3°.
[0033] In this way, the double slope adjustment mechanism is provided, that is, the preliminary height and angle adjustment can be performed through the scissor jack 1 to adapt to the slope change of less than 3°, and for the steeper slope of 3°~5°, further slope adaptation can be realized by increasing the number of standardized cushion blocks 2. The use of the standardized cushion block 2 can compensate for the insufficient jacking stroke of the scissor jack 1, and the hydraulic jack with a large weight does not need to be used, which is convenient for remote transportation. In addition, the standardized cushion blocks 2 can be replaced with each other, and the number thereof can be increased or decreased flexibly according to the terrain slope requirement, so that the wide adaptation to the slope change is realized. The cushion plate 3 increases the contact area with the ground, can disperse the pressure, and improves the stability and adaptability on the complex terrain. The top of the scissor jack 1 supports the folding house through the connecting mounting plate 5, which ensures the reliability of the support. At the same time, the application region is wide, and the overhead mechanism can be used in the general climate condition area, the plateau area, and the environment with extremely low winter temperature in the cold region.
[0034] Specifically, in the embodiment, the base 101 of the scissor jack 1 is modified, and the length of the base 101 is increased to be equal to the length of the standardized cushion block 2, which enables the standardized cushion block 2 to provide more reliable support for the scissor jack 1.
[0035] More specifically, in the embodiment, the standardized cushion block 2 is a cavity structure made of aluminum alloy material, which can reduce the weight of the standardized cushion block 2 to achieve the purpose of weight reduction and facilitate transportation. In order to improve the reliability, a rib plate can be arranged in the cavity. In addition, in the embodiment, the height of the standardized cushion block 2 is 100 mm, which realizes the modular design, so that the standardized cushion blocks 2 can be stacked and replaced conveniently, improves the flexibility and adaptability of the overhead mechanism, and is also convenient for production and inventory management.
[0036] Particularly, in the embodiment, an anchoring device (not shown in the drawings) is further included, and the base plate 3 is provided with a through hole for passing the anchoring device. This makes the overhead mechanism more firmly fixed on the ground through the anchoring device, especially suitable for soft or unstable ground conditions, and enhances the safety of the overhead mechanism.
[0037] As an improvement, in the embodiment, the base plate 3 can be designed as a replaceable laminated structure (not shown in the drawings), and the hardness of each layer is different. This allows the user to replace the base plate layer flexibly according to the hardness and stability requirements of the ground, to achieve the best ground adaptability and shock absorption effect. Moreover, the bottom of the base plate 3 can be provided with grooves or convex points for increasing the friction to improve the anti-skid performance of the overhead mechanism on inclined or slippery ground, and ensure the stability of the house. As a further improvement, in the embodiment, a level (not shown in the drawings) can also be provided on the connecting mounting plate 5, so that when adjusting the number of standardized cushion blocks 2 or adjusting the jacking height of the scissors jack 1, the level can be used as a reference, that is, when the level shows that the connecting mounting plate 5 is in a horizontal state, it indicates that the support part has been adjusted to a horizontal state, and the influence of the slope has been eliminated, so it is very convenient to adjust the number of standardized cushion blocks 2 or the jacking height of the scissors jack 1.
