[0028] Research has found that the existing coal mine inclined fully-mechanized mining face has the problem of cable sliding down when the coal mining machine goes down to cut coal. In order to prevent the cable of the coal mining machine from accelerating down due to the large inclination angle of the working face and damaging the power cable of the coal mining machine, several operators need to be arranged to drag the cable with nylon ropes during the production feed process. However, the dragging personnel may lose their strength, which may cause the personnel to fall and collide with the working face equipment, causing injuries. Therefore, manual operation has great limitations and serious safety hazards.

[0029] In view of this, if Figure 1 and Figure 2 As shown, a damping device for preventing an inclined cable trough from sliding down may include a damping plate 10 and a connecting structure 20. The damping plate 10 is suitable for being installed on the first side frame 31 of the cable trough 30 through the connecting structure 20. The damping plate 10 is suitable for forming a limiting space with the second side frame 32 of the cable trough 30, and the distance between the damping plate 10 and the second side frame 32 can be adjusted. The damping plate 10 is suitable for pressing against the cable contained in the limiting space. The damping plate 10 is arranged to be installed on the first side frame 31 of the cable trough 30. The position between the damping plate 10 and the second side frame 32 of the cable trough 30 can define a limiting space for placing the cable, and the distance between the damping plate 10 and the second side frame 32 can be adjusted so that the width of the limiting space can be adjusted. The damping plate 10 can be used to clamp the cable placed in the space, and can prevent the cable in the inclined cable trough 30 from sliding down, thereby solving the problem of cable sliding down in the inclined comprehensive mining working face, thereby avoiding the safety hazard caused by manually dragging the cable.

[0030] like Figure 1 As shown, the damping plate 10 is installed on the first side frame 31 of the cable trough 30 through the connecting structure 20. The damping plate 10 can form a limited space for accommodating cables with the second side frame 32 of the cable trough 30. The specific structure of the connecting structure 20 is not limited here. As long as the damping plate 10 can be installed on the first side frame 31 and the distance between the damping plate 10 and the second side frame 32 can be adjusted, the purpose of the adjustable distance is to be applicable to cables of various sizes. Among them, the first side frame 31 and the second side frame 32 are two opposite sides of the cable trough 30, but it is not limited to which side of the cable trough 30 the first side frame 31 and the second side frame 32 are specifically, and can be selected in accordance with the principle of convenient installation and use when used on site. In addition, the structure of the first side frame 31 and the second side frame 32 is not limited, and can be a plate structure or a frame structure.

[0031] like Figure 1 As shown, the lower ends of the first side frame 31 and the second side frame 32 have a bottom plate 33 for placing cables. The bottom plate 33 here is not limited and can be a bottom plate 33 installed on the foundation of the actual use position, or can be a bottom plate 33 integrally formed between the first side frame 31 and the second side frame 32. A cable trough 30 for placing cables can be formed between the bottom plate 33 and the first side frame 31 and the second side frame 32.

[0032] Here, the specific shape of the damping plate 10 is not limited, and it is sufficient that the damping plate 10 and the second side frame 32 form a limiting space for placing the cable.

[0033] In the present disclosure, the damping plate 10 may include a clamping plate 13 and an upper plate 11, wherein the upper plate 11 is mounted on the upper side of the clamping plate 13, and the upper plate 11 is arranged obliquely, and the distance between the upper end of the upper plate 11 and the second side frame 32 is adapted to be greater than the distance between the lower end of the upper plate 11 and the second side frame 32. The purpose of setting the upper plate 11 is to facilitate the placement of the cable, and the upper plate 11 is inclined toward the direction of the first side frame 31, which is equivalent to the size of the upper part of the limiting space being larger than the size of the lower part, so it is convenient to operate when placing the cable in this limiting space. Here, setting the upper plate 11 on the clamping plate 13 can also prevent the edges on the upper side of the clamping plate 13 from damaging the cable.

[0034] Among them, the structure of the connection position between the upper plate 11 and the clamping plate 13 is not limited, and an obtuse angle connection or a chamfered angle connection can be set. Here, setting a chamfered angle connection between the clamping plate 13 and the upper plate 11 can also prevent the edges of the connection between the clamping plate 13 and the upper plate 11 from damaging the cable.

[0035] In the present disclosure, the damping plate 10 may include two side plates 12, which are respectively mounted on both sides of the abutting plate 13, and the side of the side plate 12 away from the abutting plate 13 extends obliquely toward one side of the first side frame 31. The purpose of arranging the side plates 12 on both sides of the abutting plate 13 is to prevent the edges of the side of the abutting plate 13 from damaging the cable.

[0036] Among them, the structure of the connection position between the side panel 12 and the clamping plate 13 is not limited, and an obtuse angle connection or a chamfered angle connection can be set. Here, setting a chamfered angle connection between the clamping plate 13 and the side panel 12 can also prevent the edges of the connection between the clamping plate 13 and the side panel 12 from damaging the cable.

[0037] In the present disclosure, the connection position between the upper plate 11 and the abutting plate 13 can be configured as an arc portion; the connection position between the side plate 12 and the abutting plate 13 can be configured as an arc portion. The connection positions between the abutting plate 13 and the upper plate 11 and the side plate 12 are all configured as arc portions, which can ensure that the damping plate 10 will not damage the cables placed there.

[0038] Here, an arc portion facing the first side frame 31 may be provided at the edge of the lower end of the abutting plate 13 to prevent the cable from being damaged by friction between the lower end of the abutting plate 13 and the cable when the cable is placed at this position.

[0039] In the present disclosure, the connection structure 20 may further include a mounting plate 21, and the mounting plate 21 is suitable for being fixedly mounted on the first side frame 31, and the mounting plate 21 is used to mount the damping plate 10. The purpose of providing the mounting plate 21 is to facilitate the installation of the damping plate 10. Since the structures of the first side frame 31 and the second side frame 32 are not limited, in actual application, the first side frame 31 and the second side frame 32 may be frames, plate-like structures or other side frame structures. Therefore, the mounting plate 21 is provided and mounted on the first side frame 31, and the damping plate 10 can be mounted on the mounting plate 21, so there is no need to directly mount the damping plate 10 on the first side frame 31, which can facilitate the installation of the damping plate 10.

The function of the connection screw 22 is to connect the damping plate 10 and the mounting plate 21. The length of the connection screw 22 between the damping plate 10 and the mounting plate 21 is adjustable, so the connection screw 22 is convenient for adjusting the width of the limiting space, and the width here refers to the distance between the first side frame 31 and the second side frame 32. The function of the locking member is to fix the connection screw 22 to the mounting plate 21.

[0041] Among them, one end of the connecting screw 22 is connected to the damping plate 10, and the specific connection method is not limited. The connection can be made by fixed connection or sleeve connection.

The elastic pressing member 23 is pressed against the first surface of the mounting plate 21 and the pressing plate 13, so that the sliding of the damping plate 10 can be prevented by the elastic force of the elastic pressing member 23, so that the position of the damping plate 10 can be adjusted and has a pressing effect tending to the direction of the cable.

[0043] The limiting block is used as a limiting member 221 at the end of the connecting screw 22, and the purpose is to ensure that the screw is inserted into the second mounting hole and does not slip out of the second mounting hole. The limiting member 221 is used in conjunction with the elastic pressing member 23, so that the damping plate 10 is pressed at the position of the end of the connecting screw 22.
