Description

Technical Field

[0001] This utility model relates to the field of hydraulic support technology, specifically to a transverse arc-shaped telescopic full-section advanced support hydraulic support. Background Technology

[0002] Laterally curved, telescopic, full-section advanced support hydraulic supports are support equipment used in underground mining operations such as coal mines for tunnel excavation. Thanks to their lateral telescopic nature, they can adapt to tunnel cross-sections of varying widths. The curved top beam design better conforms to the curved contour of the tunnel roof, enhancing the contact area and stability between the support structure and the roof. This support provides advance support ahead of the tunnel excavation work area, using a hydraulic system to quickly raise, lower, and move the support, actively supporting the tunnel roof and sides. This effectively prevents rockfall and deformation caused by excavation disturbances, providing a safe and stable working space for excavation personnel and equipment, and ensuring the safe and efficient progress of tunnel excavation.

[0003] In the prior art, a transverse arc-shaped telescopic full-section advanced support hydraulic support with patent publication number 201720682625.X includes a base, on which a vertical lifting cylinder is installed. A top support is connected to the cylinder rod of the lifting cylinder, and an arc-shaped top is directly or indirectly connected to the top support. The arc-shaped top protrudes upward, and side guard plates are rotatably installed on the lower parts of both sides of the arc-shaped top. Side guard plate drive cylinders are installed on the top support corresponding to the side guard plates on both sides. The cylinder rods of the side guard plate drive cylinders are respectively connected to the corresponding side guard plates on both sides. A push-pull cylinder in the front-to-back direction is installed on the base for connecting adjacent hydraulic supports. Using this support greatly reduces the manpower and material consumption in support operations and can significantly improve production efficiency.

[0004] In coal mining, groundwater seeps into the surrounding tunnels through rock fissures and other channels due to mine pressure. Since the top of the arched roof supporting the tunnel is connected to this seepage area, groundwater accumulates at the top of the arched roof. The structure of the arched roof prevents the water from being retained for long periods, causing it to flow to the tunnel floor, making the floor slippery. This not only increases the risk of workers slipping and getting injured, but also poses a potential threat to electrical equipment, such as causing dampness and leakage, thus affecting the safety and continuity of coal mining. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a transverse arc-shaped telescopic full-section advanced support hydraulic support, which can effectively solve the problem that the arc-shaped top structure in the existing technology makes it impossible for water to be retained for a long time, and it will flow to the tunnel floor, causing the tunnel floor to be slippery.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a transverse arc-shaped telescopic full-section advanced support hydraulic support, including a support assembly, including a hydraulic support body, a base fixed at the bottom of the hydraulic support body, and a side guard provided on one side of the hydraulic support body.

[0008] A support assembly is disposed on the top of the hydraulic support body, including a support member, the support member including an arc-shaped top, the arc-shaped top being fixed to the top of the hydraulic support body, and a baffle being fixed on one side of the side guard.

[0009] The support assembly also includes a functional component, which includes a guide tube inserted into the bottom of the arc-shaped top and communicating with the top of the arc-shaped top.

[0010] Furthermore, a filter screen is fixed to the top of the inlet pipe, and the filter screen has a convex surface.

[0011] Furthermore, a storage box is fixed to one end of the inlet tube, and a guide plate is fixed inside the storage box.

[0012] Furthermore, a water outlet frame is fixed to the bottom of the storage box, and a sealing cover is hinged to one side of the water outlet frame.

[0013] Furthermore, a sealing ring is fitted on the outside of the sealing cover, and one end of the sealing cover is set as a conical surface.

[0014] Furthermore, the support assembly also includes a protective component, which includes a rotating column fixed to the inner wall of the shield.

[0015] Furthermore, a positioning plate is rotatably connected to the outside of the rotating column, and the positioning plate is fixed to the top of the hydraulic support body.

[0016] Compared with the known prior art, the technical solution provided by this utility model has the following beneficial effects: the guide grooves set on both sides of the top of the arc-shaped top can collect water before discharge. The guide grooves can collect and discharge the water accumulated on the top of the arc-shaped top in a directional manner, preventing the water from flowing randomly along the arc-shaped top to the roadway floor, preventing the ground from becoming slippery, reducing the risk of workers slipping and getting injured, providing a safe walking and operating environment for underground workers, and preventing water from coming into contact with electrical equipment in the roadway when it flows in a disorderly manner, thus reducing the probability of equipment getting damp.

[0025] 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: A transversely arc-shaped, telescopic, full-section advanced support hydraulic support, see attached figure. Figure 1 -Appendix Figure 6The system includes a support assembly 1, a hydraulic support body 11, a base 12 fixed to the bottom of the hydraulic support body 11, and a side guard 13 provided on one side of the hydraulic support body 11.

[0028] The support body 11 uses a hydraulic system to lift, lower, and move the support, supporting the roadway roof, resisting pressure, and preventing roof collapse. The base 12 transfers the roof pressure borne by the support body 11 to the roadway floor, while providing a stable installation foundation for the support body 11, ensuring that the support body 11 does not tilt or sink. The side protection 13 is a side protection component of the support body 11, used to fit the roadway, prevent coal from falling from the side, prevent deformation and collapse of the coal in the side, and ensure the safety of the side of the underground working space. The support assembly 2 is set on the top of the support body 11 and includes a support member 21, which includes an arc-shaped top 211 fixed to the top of the support body 11. A baffle 212 is fixed on one side of the side protection 13.

[0029] Support component 2 is disposed on the top of hydraulic support body 11 and includes support member 21. Support member 21 includes arc-shaped top 211, which is fixed to the top of hydraulic support body 11. A baffle 212 is fixed on one side of the side guard 13.

[0030] The arc-shaped roof 211 conforms to the contour of the coal mining face roof through its arc structure, increasing the contact area with the roof and evenly bearing and transmitting the roof pressure to the support body 11, thereby achieving stable support for the roof, preventing roof collapse or deformation, and ensuring the safety of the top of the working space. When the side guard 13 rotates, it can drive the baffle 212 to rotate around the side guard 13. The baffle 212 can protect the hinge joint between the side guard 13 and the support body 11, preventing coal and rock fragments from entering the hinge joint and avoiding fragments from jamming the hinge components. The baffle 212 ensures that the side guard 13 rotates flexibly and does not affect the adjustment function of the side guard 13.

[0031] Specifically, the support component 2 also includes a functional component 22, which includes a guide tube 221. The guide tube 221 is inserted into the bottom of the arc-shaped top 211 and is connected to the top of the arc-shaped top 211.

[0032] The functional components 22 are in two sets, both located on the top of the arc-shaped top 211. There are five inlet pipes 221, which are installed horizontally side by side at the bottom of the arc-shaped top 211 to guide the water accumulated on the top of the arc-shaped top 211. Finally, the water is transported and discharged in a preset direction to prevent the water from flowing randomly on the top of the arc-shaped top.

[0033] Furthermore, a filter screen 222 is fixed to the top of the inlet pipe 221, and the filter screen 222 has a convex surface.

[0034] The convex filter screen 222, with its high hardness and strong wear resistance, is used to filter impurities and protect the drainage pipe 221. It can prevent solid impurities such as coal slag and rock chips from entering the interior of the pipe 221, thus avoiding blockage of the pipe 221 channel and affecting drainage. At the same time, the highly wear-resistant material of the filter screen 222 can withstand the frequent friction and impact of impurities in the well, maintaining the filtration effect for a long time and ensuring that the water accumulated at the top of the arc-shaped top 211 can be smoothly discharged through the pipe 221.

[0035] Preferably, a storage box 223 is fixed to one end of the inlet pipe 221, and a guide plate 224 is fixed inside the storage box 223.

[0036] The guide plate 224 is set as an inclined surface. The water transported by the inlet pipe 221 can be collected by the storage box 223. Then, the water is guided by the inclined guide plate 224 to flow quickly along the inclined surface to the designated outlet of the storage box 223.

[0037] It should be noted that a water outlet frame 225 is fixed to the bottom of the storage box 223, and a sealing cover 226 is hinged to one side of the water outlet frame 225.

[0038] The water outlet frame 225 is a dedicated channel for draining accumulated water. It is used to guide the accumulated water after it has been guided by the guide plate 224 to the storage box, ensuring a stable drainage path. The sealing cover 226 can be closed and sealed to the water outlet frame 225 under normal conditions, and can be opened when drainage is needed, without obstructing the drainage of accumulated water.

[0039] Furthermore, a sealing ring 227 is fitted on the outside of the sealing cover 226, and one end of the sealing cover 226 is set as a conical surface.

[0040] The sealing ring 227 is used to fill the gap between the sealing cover 226 and the water outlet frame 225, enhance the sealing performance when the two are closed, and prevent water from leaking out from the gap. The conical structure of the sealing cover 226 can guide the sealing cover 226 to be inserted into the water outlet frame 225 more smoothly, reduce the difficulty of alignment when closing, and improve the ease of operation.

[0041] Specifically, the support component 2 also includes a protective component 23, which includes a rotating column 231 fixed to the inner wall of the cover 212.

[0042] When the shield 212 rotates, it can drive the rotating column 231 to rotate. The rotating column 231 can serve as a support structure for the shield 212, enhancing the overall rigidity of the shield 212, preventing the shield 212 from deforming during rotation and rock impact, and ensuring the protective effect at the hinge joint between the sidewall 13 and the support body 11.

[0043] Preferably, a positioning plate 232 is rotatably connected to the outside of the rotating column 231, and the positioning plate 232 is fixed to the top of the hydraulic support body 11.

[0044] The positioning plate 232 is fixed to the top of the bracket body 11 to form a rigid installation base. Its rotational connection structure with the rotating column 231 allows the rotating column 231 to rotate with the guard 212, providing a rotation fulcrum to ensure that the guard 212 rotates smoothly and with a stable trajectory. At the same time, it can limit the radial displacement of the rotating column 231 to prevent the guard 212 from deviating from the protective position due to shaking. This ensures that the guard 212 always covers the hinge between the guard 13 and the bracket body 11, thereby playing a protective role.

[0045] In use, the support body 11 is first placed stably in the designated position in the roadway via the base 12. Then, the hydraulic system is activated to raise the support body 11. The support body 11 drives the arc-shaped top 211 to rise and fit against the roadway roof. The arc-shaped top 211 increases the contact area with the roof through its arc structure, evenly bearing the pressure of the roof and preventing the roof from collapsing. At the same time, the side guard 13 is adjusted to fit against the roadway side. The side guard 13 drives the baffle 212 to rotate around the rotating column 231. The baffle 212 covers the hinge point between the side guard 13 and the support body 11, preventing coal and rock fragments from entering the jamming parts, ensuring the side guard 13 can rotate flexibly, preventing coal from falling from the side, and ensuring the safety of the working space.

[0046] Groundwater seeping from the tunnel roof collects along the top guide groove of the arc-shaped roof 211 and flows to the inlet pipe 221. The filter screen 222 at the top of the inlet pipe 221 filters coal slag and rock debris to prevent clogging of the inlet pipe 221. The accumulated water flows into the storage box 223 through the inlet pipe 221. The guide plate 224 inside the storage box 223 guides the accumulated water to the outlet frame 225. When drainage is needed, the sealing cover 226 on one side of the outlet frame 225 is opened, and the accumulated water is discharged through the outlet frame 225. When drainage is not needed, the sealing cover 226 is closed, and the sealing ring 227 seals the gaps to prevent leakage, prevents the accumulated water from flowing disorderly to the tunnel floor, prevents the ground from becoming slippery, reduces the risk of people slipping, and reduces the probability of electrical equipment getting damp.

[0047] If the position of the support needs to be adjusted, the hydraulic system is activated to lower the support body 11, push the base 12 to the new position, and then raise the support again. The above-mentioned roof support and side protection operations are repeated. The entire process achieves stable support of the entire cross section of the roadway and orderly drainage of accumulated water, ensuring the safety and continuous operation of coal mining, and improving the safety of the underground working environment and the reliability of the support.

[0048] In summary, by setting guide channels on both sides of the top of the arc-shaped roof 211, water can be collected and then discharged. The guide channels can collect and direct the water accumulated on the top of the arc-shaped roof 211, preventing water from flowing randomly along the arc-shaped roof to the roadway floor, preventing the ground from becoming slippery, reducing the risk of workers slipping and getting injured, providing a safe walking and operating environment for underground personnel, and preventing water from coming into contact with electrical equipment in the roadway when it flows randomly, thus reducing the probability of equipment getting damp.
