[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] In the above description of this utility model, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0035] Please see Figure 1-6 This utility model provides a technical solution: a mine anti-collapse support device, including a first support plate 1, a second support plate 2, multiple first support legs and multiple second support legs. The second support plate 2 is connected to the first support plate 1 in a horizontally slidable manner. The multiple first support legs are used to horizontally support the first support plate 1, and the multiple second support legs are used to horizontally support the second support plate 2. Both the first support legs and the second support legs are vertically extendable structures.

[0036] The first support plate 1 has a T-shaped groove 33 on its lower surface along its length. A T-shaped slider 34 is slidably fitted inside the T-shaped groove 33. The T-shaped slider 34 protrudes out of the T-shaped groove and is fixedly connected to the second support plate 2. That is, the second support plate 2 is slidably fitted to the first support plate 1 through the sliding support structure formed by the T-shaped slider 34 and the T-shaped groove 33, so that the second support plate 2 can be connected to the first support plate 1 in a way that allows it to slide in the horizontal direction.

[0037] Furthermore, the first support plate 1 and the second support plate 2 are supported by multiple first support legs and multiple second support legs respectively. When multiple first support legs and multiple second support legs are in contact with the ground, the first support plate 1 and the second support plate will simultaneously form a support structure.

[0038] Since both the first and second support legs are telescopic structures, meaning they can both extend or retract, when the support position needs to be changed, the second support leg can be adjusted while the first support leg is in a supporting state, causing the second support leg to retract and its lower end to detach from the ground. Since the first support plate 1 is in a supporting state, the second support plate 2 will be suspended on the first support plate 1 through a sliding support structure. Then, the second support plate 2 will be pushed to move along the T-shaped slide groove 33. After moving to the predetermined position, the second support leg can be adjusted to extend and contact the ground, thus restoring the state where the first support plate 1 and the second support plate simultaneously form a support structure.

[0039] As described above, by adjusting and shortening the first support leg while maintaining the support of the second support leg, the first support plate 1 can also slide along the T-shaped groove 33 on the second support plate 2 through the sliding support structure.

[0040] Therefore, by alternating the support states of the first support plate 1 and the second support plate 2, the two can support each other and change their support positions in the mine tunnel by sliding.

[0041] In this embodiment, a first linear reciprocating telescopic mechanism (3) is also included. One end of the first linear reciprocating telescopic mechanism (3) is fixedly connected to the first support plate (1), and the other end of the first linear reciprocating telescopic mechanism is fixedly connected to the second support plate (2).

[0042] When it is necessary to adjust the distance between the first support plate 1 and the second support plate 2, the first linear reciprocating telescopic mechanism 3 can be used as a power source for easy operation. The two ends of the first linear reciprocating telescopic mechanism 3 are fixedly connected to the lower surface of the first support plate 1 and the upper surface of the second support plate 2, respectively. Its telescopic direction is parallel to the length direction of the first support plate 1 and the second support plate 2. That is, the force direction of the first linear reciprocating telescopic mechanism 3 is parallel to the sliding trajectory of the first support plate 1 and the second support plate 2, thereby reducing force loss.

[0043] In this embodiment, the first support leg includes a first rod 4 disposed on the lower side of the first support plate 1 and a second linear reciprocating telescopic mechanism 5 disposed at the lower end of the first rod 4, with the output end of the second linear reciprocating telescopic mechanism 5 facing downward; the second support leg includes a second rod 6 disposed on the lower side of the second support plate 2 and a third linear reciprocating telescopic mechanism 7 disposed at the lower end of the second rod 6, with the output end of the third linear reciprocating telescopic mechanism 7 facing downward.

[0044] The lower ends of the first rod 4 and the second rod 6 are connected to one end of the second linear reciprocating telescopic mechanism 5 and the third linear reciprocating telescopic mechanism 7, respectively. At that time, the second linear reciprocating telescopic mechanism 5 and the third linear reciprocating telescopic mechanism 7 extend, and the first support leg and the second support leg contact the mine ground for support.

[0045] Both the second linear reciprocating mechanism and the third linear reciprocating drive mechanism have a fixed end and a movable end. The fixed end serves as a mounting part and is connected to the first rod 4 and the second rod 6. The movable end serves as an output end and can be extended or shortened under power. That is, the first rod 4 and the second rod 6 respectively form a first support leg and a second support leg that can be extended and shortened vertically through the linear extension 7.

[0046] The first linear reciprocating drive mechanism, the second linear reciprocating drive mechanism, and the third linear reciprocating telescopic mechanism can all be any one of hydraulic telescopic rods, pneumatic telescopic rods, or electric telescopic rods.

[0047] In this embodiment, the first support leg further includes a first pad 8, which is fixed to the lower end of the second linear reciprocating telescopic mechanism 5. The second support leg further includes a second pad 9, which is fixed to the lower end of the third linear reciprocating telescopic mechanism 7.

[0048] The first pad 8 and the second pad 9 are fixedly connected to the lower ends of the locking parts of the second linear reciprocating telescopic mechanism 5 and the third linear reciprocating telescopic mechanism 7, respectively, increasing the contact area between the first support leg and the second support leg and the mine floor, making the support equipment more stable.

[0049] In this embodiment, the lower side of the first pad 8 protrudes downward to form a plurality of first anti-slip teeth 10, and the lower side of the second pad 9 protrudes downward to form a plurality of second anti-slip teeth 11.

[0050] The first anti-slip protrusion 10 and the second anti-slip protrusion 11 are respectively disposed on the lower surface of the first pad 8 and the second pad 9, and are integrally formed with the first pad 8 and the second pad 9.

The first hinge shaft 13 is located in the first shaft hole 14 and cooperates with the first shaft hole 14.

[0055] The first support plate 1 has two hinge seats at each of two adjacent included angle positions. The hinge shaft on one hinge seat is set along the length direction of the first support plate 1, and the hinge shaft on the other hinge seat is set along the width direction of the first support plate 1. The shortest length of the first support leg is less than the length and width of the first support plate 1. The first hinge shaft 13 located in the first shaft hole 14 cooperates with the first shaft hole 14, so that the first support leg can rotate relative to the axis of the first support plate 1 with the first hinge shaft 13 as the axis and can rotate to a vertical or horizontal position for the support and transportation of this support equipment.

[0056] The second support leg includes components such as the second hinge shaft 16, the second ear plate 15, the second support plate 2, the second rod 6, and the second shaft hole 17. Its working principle and technical effect are the same as those of the first hinge shaft 13, the first ear plate 12, the first support plate 1, the first rod 4, and the first shaft hole 14.

[0057] In this embodiment, a first pin hole 18 and a second pin hole 19 are formed on the first ear plate 12. A first groove 20 is formed by recessing the upper end of the first rod 4 towards the side facing the first pin hole 18. The first groove 20 is directly opposite the first pin hole 18 when the first rod 4 is in a vertical state, and directly opposite the second pin hole 19 when the first rod 4 is in a horizontal state. The first locking assembly includes a first pin 21 and a first helical spring 22.

The first lever 29 is moved until it is engaged in the first strip hole 28. At this time, the first support leg can rotate relative to the first support plate 1 axis with the first hinge shaft 13 as the axis. Multiple first support legs can be adjusted to a vertical support state or a horizontal folding state.
