[0033] See also Figure 1-7The present invention provides a safety protection support device for underground mining sites, comprising two left and right bases 1 and a support body 6 arranged between the two bases 1. The base 1 is used to be placed on the ground under the mine to support the support device. When the support device is supporting, it guides and disperses the external force. A pouring stabilization mechanism 11 is provided at the bottom of the base 1, and a pouring port 10 of the pouring stabilization mechanism 11 longitudinally penetrates the top of the base 1 and extends upward. A hydraulic device 12 is provided at the top of the base 1, and the top telescopic end of the hydraulic device 12 is connected to the support seat 4. The hydraulic device 12 can support the support seat 4, and the support seat 4 and The side opposite to the hydraulic device 12 is connected to the top seat 5 through a buffer mechanism, and a preliminary supporting effect can be achieved through the top seat 5 and the buffer mechanism. A supporting arm 2 is hinged on the top of the base 1, and the other end of the supporting arm 2 is hinged to one end of the supporting arm 3, and the other end of the supporting arm 3 is hinged to one end of the fixed seat 21. A hydraulic device 23 is provided in the fixed seat 21, and the telescopic end of the hydraulic device 23 is hinged to the connecting seat 22.

The hydraulic device 23 and the hydraulic device 12 can both support the supporting seat 4, thereby achieving a secondary supporting effect.

[0034] The perfusion stabilization mechanism 11 includes a perfusion port 10, a perfusion tube body 20, a limit block 25 fixed at the bottom of the outer wall of the perfusion tube body, a movable seat 26 sleeved on the outer wall of the perfusion tube body, a bag body 24 and a counterweight seat 27. The perfusion tube body 20 is fixed in the base 1, and one end of the perfusion tube body 20 is connected to the perfusion port 10, and the other end of the perfusion tube body 20 longitudinally penetrates the base 1 and extends to the bottom.

[0035] The movable seat 26 is sleeved on the outer wall of the extended end of the perfusion tube body. The movable seat 26 is connected to the counterweight seat 27 through the bag body 24. The bag body 24 is composed of cloth or metal mesh. The cloth or metal mesh can discharge the moisture of the slurry poured into the bag body 24, thereby ensuring the stability of the slurry in the bag body 24 after molding.

[0036] The present invention uses a perfusion stabilization mechanism to inject slurry into the bag body through the perfusion port. At the same time, the perfusion pipe and the base are integrally formed. When the supporting structure on the base is subjected to external force, the perfusion stabilization mechanism underground can transmit and evenly disperse the force on the base, thereby ensuring the stability of the supporting device.

[0041] The buffer mechanism includes a movable column 13, a spring 14 sleeved on the outside of the movable column 13, a guide column inserted in the movable column 13, and a spring 2 sleeved on the outer wall of the guide column. A movable groove capable of accommodating the movable column 13 is provided on the support seat 4, and one end of the movable column 13 is connected to the top seat 5, the other end of the movable column 13 passes through the movable groove and enters the support seat 4, and one end of the guide column is fixed to the bottom of the support seat 4, and the other end of the guide column is inserted in the slot provided in the movable column 13, the two ends of the spring 14 are respectively connected to the bottom of the top seat 5 and the top of the support seat 4, and the two ends of the spring 2 are respectively connected to the bottom of the movable column 13 and the bottom of the support seat 4.

[0042] A cross bar 16 is horizontally arranged inside the support seat 4, and both ends of the cross bar 16 are sleeved with a sliding seat 17 and a spring three 18. A limit plate 15 is arranged on the outer wall of one end of the movable column 13 entering the support seat 4, and a connecting rod 19 is hinged on the limit plate 15. The other end of the connecting rod 19 is hinged to the sliding seat 17, and both ends of the spring three 18 are respectively connected to the sliding seat 17 and the inner wall of the support seat 4.

[0043] Working principle: When in use, the counterweight seat 27 is placed in the pre-excavated pit, and the base 1 is placed on the ground under the mine, and cement slurry is poured into the filling port 10. The cement slurry enters the bag body 24 through the filling tube. As the cement slurry is poured into the bag body 24, it deforms and its volume increases laterally to fill the pit under the mine, thereby ensuring the stability of the bottom of the base 1. When the volume of the bag body 24 increases, it drives the movable seat 26 to slide downward on the filling tube. The limit block 25 is used to limit the movable seat 26. The hydraulic device 1 12 and the hydraulic device 2 23 can both play a role in supporting the support seat 4. The supporting body 6 is a prefabricated cement part. The multiple curved metal plates 9 in the supporting body 6 can support the supporting body 6. The multiple curved metal plates 9 are connected by metal connecting strips 8 and metal meshes 32 to increase the stress between the curved metal plates 9 and the supporting body 6 and ensure the stability of the supporting device. The initial supporting effect can be achieved through the top seat 5 and the buffer mechanism. At the same time, the secondary supporting protection can be achieved through the supporting body 6. The supporting structure formed by the metal mesh 32 in the supporting body 6 and the curved metal plates 9 and the metal connecting strips 8 can achieve tertiary supporting protection.
