Description

Technical Field

[0002] The end of the comprehensive mining working face is the intersection of the mining working face and the mining tunnel. There are dense equipment here, and it is the throat of pedestrians, ventilation, material transportation and raw coal transshipment. Moreover, this area is located in the area where the mine pressure is most obvious and is most affected by mining. The quality of its support and management is crucial to whether the working face can operate safely and efficiently, and has the greatest impact on the safe and efficient production of the working face.

[0003] In the existing technology, during the use of conventional hydraulic support groups for coal mines, the top beam area is fixed, resulting in a limited support area. In the support process, the top beam cannot protect the side of the tunnel, and coal leakage occurs on the side wall of the tunnel. At the same time, during the movement of the hydraulic support group, the hydraulic support group needs to retract and cannot support the top of the tunnel. At the same time, the movement of the hydraulic support group itself lacks a stable structure, and there is a safety hazard of tipping over during use. Utility Model Content

The base 1 is connected to the right side of the top beam 5 by a connecting mechanism 7, and a front beam mechanism 8 is provided on the left side of the top beam 5. Mounting frames 9 are fixedly installed on the upper near left and right positions of the top beam 5, and supporting mechanisms 10 are installed on the lower inner walls of the mounting frames 9. The front and rear sides of the reinforcement block 6 are located at the front and rear sides of the top beam 5, and protective mechanisms 11 are fixedly installed.

[0020] Specifically, the connecting mechanism 7 includes a fifth hinge 701, a connecting rod 702, a sixth hinge 703, a shielding beam 704 and a seventh hinge 705. The right side wall of the base 1 is equipped with two connecting rods 702 through the fifth hinge 701. The upper surface of the connecting rod 702 is equipped with a shielding beam 704 through the sixth hinge 703. The left end of the shielding beam 704 is connected to the top beam 5 through the seventh hinge 705.

[0021] In this embodiment, a four-bar linkage is formed between the base 1 , the connecting rod 702 , the shield beam 704 and the top beam 5 , which stabilizes the hydraulic support assembly.

[0022] Specifically, the front beam mechanism 8 includes a front beam plate 801, a third hinge 802, a front beam jack 803 and a fourth hinge 804. The right end of the front beam plate 801 is connected to the left end of the top beam 5 near the upper position through the third hinge 802. The middle part of the lower surface of the front beam plate 801 and the left side of the top beam 5 are both provided with a fourth hinge 804, and the left and right fourth hinges 804 are connected by the front beam jack 803.

[0023] In this embodiment, the front beam jack 803 pushes the front beam plate 801 to rotate along the third hinge 802 through the fourth hinge 804, so that the front beam plate 801 jointly supports the top plate.

[0024] Specifically, the cross section of the mounting frame 9 when viewed from the right is a U-shaped structure.

[0025] In this embodiment, the mounting bracket 9 facilitates the installation and fixation of the supporting mechanism 10 .

[0026] Specifically, the support mechanism 10 includes a support jack 101, a mounting box 102, a belt conveyor assembly 103 and a rectangular opening 104. The support jack 101 is installed on the lower inner wall of the mounting frame 9. The upper surface of the support jack 101 is fixedly installed with a mounting box 102. The upper surface of the mounting box 102 is fixedly installed with a belt conveyor assembly 103, and a rectangular opening 104 is opened on the top beam 5 corresponding to the belt conveyor assembly 103.

[0027] In this embodiment, the piston rod of the supporting jack 101 drives the installation box 102 to move upward, so that the belt conveyor assembly 103 in the installation box 102 passes through the rectangular opening 104 and is pressed against the top plate.

[0028] Specifically, the protective mechanism 11 includes a side push jack 111 and a side guard plate 112. The side push jack 111 is fixedly installed on the front and rear sides of the reinforcement block 6. The side of the side push jack 111 away from the reinforcement block 6 is fixedly installed with a side guard plate 112, and the side guard plate 112 is an inverted L-shaped structure.

[0029] In this embodiment, the front and rear side push jacks 111 push the side guard plates 112 to move in a direction away from the top beam 5. The side guard plates 112 can jointly support the top plate and increase the side protection function.

[0030] When in use, the top beam 5 is driven upward by the hydraulic telescopic rod 3, and the top beam 5 is supported on the lower surface of the top plate, and then the side push jacks 111 in the front and rear of the protective mechanism 11 push the side guard plates 112 to move in the direction away from the top beam 5. The side guard plates 112 can jointly support the top plate, increase the supporting area of ​​the top beam 5, and make the supporting effect better. In addition, the side guard plates 112 increase the support of the hydraulic support group for the side walls of the tunnel, effectively preventing coal leakage, and making it safer to use. Then, the front beam jack 803 in the front beam mechanism 8 pushes the front beam plate 801 to rotate along the third hinge 802 through the fourth hinge 804, so that the front beam plate 801 jointly supports the top plate When the hydraulic support group needs to be moved, the hydraulic telescopic rod 3 drives the top beam 5 to reset downward, so that the top beam 5 and the side guard plate 112 are separated from the top plate. At this time, the piston rod of the support jack 101 in the support mechanism 10 drives the installation box 102 to move upward, so that the belt conveyor assembly 103 in the installation box 102 is pressed against the top plate through the rectangular opening 104. The hydraulic support group can also support the top of the tunnel during the movement, and the belt conveyor assembly 103 can move and rotate with the top beam 5, so that the upper and lower sides of the hydraulic support group are subjected to force, thereby making the movement process of the hydraulic support group more stable, not easy to tip over, and safer to use.

[0031] To sum up, the hydraulic support group structure used in the coal mine increases the support area of ​​the top beam 5, making the support effect better, and increases the support of the hydraulic support group to the side wall of the tunnel, effectively preventing coal leakage, and making it safer to use. The hydraulic support group can also support the top of the tunnel during movement, and makes the movement process of the hydraulic support group more stable and safer to use.
