[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0024] The following describes the single-body support connection device of the utility model embodiment with reference to the accompanying drawings. Figures 1 to 4 As shown, the single-body pillar connecting device according to the embodiment of the utility model comprises a plurality of single-body pillars 1, a plurality of fixing members and a plurality of connecting members 2.

[0025] The single pillar 1 is used for tunnel support. A plurality of fixings are connected to the multiple single pillars 1 in a one-to-one correspondence. Each connecting member 2 includes two connecting parts 4, and the distance between the two connecting parts 4 of each connecting member 2 is adjustable. The two connecting parts 4 of each connecting member 2 are respectively connected to the fixings on two adjacent single pillars 1. Thus, a plurality of single pillars 1 can be connected in series through a plurality of fixings and a plurality of connecting members 2, so as to realize series chain anti-collapse. The distance between the two connecting parts 4 of each connecting member 2 is adjustable, so that the single pillar 1 can be tensioned to reduce the deviation of the single pillar 1. Therefore, after the single pillar 1 is automatically depressurized, it is not easy to fall over and injure people, so as to increase the safety of mining.

[0026] Therefore, the single-body pillar connection device according to the embodiment of the utility model can increase the advantage of mining safety.

[0027] like Figures 1 to 3 As shown, in some embodiments, the fixing member includes a fixing rope 5, and the two connecting parts 4 of each connecting member 2 are respectively connected to the fixing rope 5. Specifically, the fixing rope 5 is a steel wire rope, and the fixing rope 5 can be tied to the single pillar 1, so that the fixing rope 5 can be connected to the single pillar 1. The end of the fixing rope 5 is made into a hanging ring 6, and the end of the fixing rope 5 is connected to the connecting part 4 of the connecting member 2. In this way, a plurality of single pillars 1 can be connected in series through a plurality of fixing members and a plurality of connecting members 2. The single pillars 1 are connected by the fixing rope 5 to achieve flexible series connection between the single pillars 1, so that the compression deformation effect is good, it can better adapt to the large deformation lane, and it is easy to untie and reuse. For example, the steel wire rope is a 3-point steel wire rope.

[0028] like Figure 2 and Figure 3 As shown, in some embodiments, a plurality of single pillars 1 are spaced apart in the first direction. The fixing member includes a fixing clamp 7 and a fixing rope 5. The fixing clamp 7 is clamped on the single pillar 1, and both ends of the fixing clamp 7 in the first direction are provided with fixing holes, one end of the fixing rope 5 is connected to a fixing hole of the fixing clamp 7, and the other end of the fixing rope 5 is connected to a connecting portion 4 of the connecting member 2. Thus, a plurality of single pillars 1 can be connected in series through a plurality of fixing members and a plurality of connecting members 2. The first direction can be a front-to-back direction. For example, a plurality of single pillars 1 are spaced apart in the front-to-back direction. The fixing clamp 7 is provided with fixing holes at both ends in the front-to-back direction.

[0029] In some embodiments, the connector 2 includes a connector frame 3 and two connectors 4, and the two connectors 4 are movably arranged on the connector frame 3 along the length direction of the connector frame 3. Specifically, screw holes are arranged on both sides of the length direction of the connector frame 3. The connector 4 is a connecting hook, which is used to connect to the fixing member, and the connecting hook is threadedly connected to the screw hole. Therefore, the connecting hook can be rotated so that the connecting hook moves in the length direction of the connector frame 3, thereby making the distance between the two connecting parts 4 of each connector 2 adjustable. For example, the connecting hook is hung on the hanging ring 6 of the fixing rope 5.

[0030] In some embodiments, a plurality of single pillars 1 are arranged at intervals in the first direction. The fixing member on the outermost single pillar 1 in the first direction among the plurality of single pillars 1 is connected to the top of the tunnel through the connecting member 2. The head and tail single pillars 1 are rooted to the top plate through the connecting member 2 to further prevent the single pillars 1 from falling.
