Problems solved by technology

The disadvantage of this type of support device is that in the environment of an uneven support base, the fixed support point cannot keep the center of gravity of the supported object in line with the most stable position of the design as in the case of a flat support base. The center of gravity of the supported object is prone to roll due to deviation from the stable point. In order to overcome this defect, it is necessary to constantly adjust the position of the supported object to make the center of gravity right, making the placement of the supported object troublesome.
[0004] For the straight-down linear expansion method, the support point is located on the axis of the linear expansion. Under the environment of uneven support base, the expansion and contraction length of different support feet can be adjusted separately, so that it is suitable for various application environments. Good adaptability, but this type of supporting device also has shortcomings
The telescopic support feet are straight-down type. To achieve telescopic expansion, it must occupy the space of the corresponding telescopic path, that is, the vertical space of the supported object, resulting in a waste of effective space for the supported object.
[0005] Chinese patent CN201021315Y discloses an improved locomotive tripod structure, which is characterized in that a tripod is provided at the bottom of a locomotive, and a fixed rod is provided on it for connecting the tripod to the bottom of the car body. Pedals, and a plurality of semicircular auxiliary parts integrally formed with the tripod, although this structure can play a supporting role, but the structure occupies a large space, and the support point cannot be changed, and it cannot be docked flexibly

Embodiment 1

[0059] Such as figure 1 As shown, for a triangle composed of three sides AB, AC, and BC, changing the position of the end point C while keeping side AB unchanged can be achieved by changing the lengths of sides AC and BC, and AB and A'B' coincide , AC and A'C' have different lengths, BC and B'C' have different lengths, AC and BC uniquely determine the position of C, and A'C' and B'C' uniquely determine the position of C'. In the supporting device of the present invention, the purpose of changing the position of the supporting point is achieved by changing the length of the supporting foot with the same principle. The variable-length support feet can be hydraulic telescopic pins, or pneumatic telescopic pins, which make the support feet stretch on the axis through hydraulic pressure or air pressure; they can also be spiral telescopic pins, which make the support feet flexible through the principle of screw displacement. It expands and contracts on the axis; it can also regulat...

Embodiment 2

[0068] Figure 4 It is a schematic diagram of one short and one long supporting foot of the present invention. This embodiment is a relatively simple embodiment using the principle of equal length and variable angle. There are only two supporting legs 2, one short and one long. The movable joint 3 moves close to or away from the supporting platform 1. Example 1 is the same.

[0069] Figure 5 It is a schematic diagram of the principle of one short and one long support in the present invention. When the support device is retracted, the support platform 1 is at point C. When the support device needs support, the movable joint 3 of the long support leg moves from point A to point A', and the movable joint 3 of the short support leg moves from point B to point B' Move, the supporting platform 1 is at point C', and the supporting device completes the supporting action. The circle in the legend represents the range of motion of the independent support foot 2, and the circle form...

Embodiment 3

[0072] Figure 6 It is a schematic diagram of two short and one long supporting feet of the present invention. The two short supporting legs 2 of the present embodiment utilize the principle of equal length and variable angles to form a triangular stable structure through the two short supporting legs, and adjust the height of the triangle to change the equivalent length of the virtual supporting legs formed by it. The beneficial effect possessed by the isosceles triangle is that tangential support stresses can be overcome. When the movable joints 3 of the two short supporting legs do not move, the equivalent length of the virtual supporting legs formed by them is equivalent to being constant, and it and the long supporting legs become to utilize the principle of equal length variable angle. When the movable joints 3 of the two short supporting legs are active, the equivalent length of the virtual supporting legs formed by them changes. When the positions of the movable joint...

Abstract

The invention relates to a supporting device arranged on a supporting body to obtain stabilizing and flexibly-supporting effects. The device comprises a supporting platform, supporting legs, a power control module and guide slots, wherein the guide slots are formed in the supporting base surface of the supporting body; at least two supporting legs are arranged; one end of each supporting leg is fixed on the supporting platform; a moving joint is arranged on the other end of each supporting leg; the moving joints are connected with the guide slot in a sliding way; the number of the guide slots is smaller or equal to that of the supporting legs; and the power control module is connected with the supporting platform, the supporting legs, the moving joints and the guide slots, respectively. Compared with the prior art, the supporting device provided by the invention has the advantages of reliable support, large supporting range, flexibility, rapidness, space conservation and the like.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a supporting device. Background technique [0002] The supporting device is a device for stabilizing objects, and the objects to be stabilized include immovable objects and movable objects. Usually, the support device of the movable object is designed to realize two states of stowage and support according to the scene. The foot is in contact with the support point. [0003] In order to realize the stowage and support of the supporting feet, the supporting feet of the disclosed supporting device are designed to turn around the axis in an arc shape or straight down linearly expand and contract, and the supporting feet of the supporting device have a fixed length and a fixed shape. For the way of arc-shaped flip around the axis, the support point is located at a point on the arc of the flip plane with the length of the support foot as the radius. In order to ensure the stable balance of the...
