Description

Technical Field

[0001] This invention relates to the field of underground mining technology, specifically to a cable laying frame for underground mining. Background Technology

[0002] Cable laying racks for underground mining are specialized cable support and fixing devices adapted to the environment of underground roadways. They are mainly used for laying and fixing various types of cables such as high-voltage power cables and control signal cables. They need to adapt to the narrow, inclined, humid, dusty and vibrating environments of the roadways. Their core function is to maintain the stability of cable laying and ensure the safety of power and signal transmission for underground mining equipment.

[0003] In existing technologies, cable laying racks lack efficient moisture-proof design. The high humidity environment underground can easily cause cables to become damp and age, leading to short circuits. The angle cannot be flexibly adjusted, making it difficult to adapt to inclined and curved tunnels. This can easily cause cables to bend excessively or droop off the ground, interfering with construction. Summary of the Invention

[0004] The purpose of this invention is to provide a cable laying frame for underground mining, in order to solve the problems mentioned in the background art, such as the lack of efficient moisture-proof design of the cable laying frame, the high humidity environment underground which easily causes the cable to become damp and age, leading to short circuit faults, the inability to flexibly adjust the angle, the difficulty in adapting to inclined and curved roadways, and the easy occurrence of excessive bending or hanging of the cable off the ground, which interferes with construction.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cable laying frame for underground mining, comprising a cable laying frame, wherein a clamping component is provided inside the cable laying frame, and an adjusting component is provided inside the cable laying frame; The clamping assembly includes multiple first air rods, and each of the multiple first air rods has a first piston slidably embedded inside. Each of the multiple first pistons has a movable rod fixedly connected to its outer surface, and each of the multiple movable rods has a clamping frame fixedly connected to its side away from the first piston. Each of the multiple first air rods has an air supply pipe fixedly connected inside, and a fixed frame is provided at the end of the air supply pipe away from the first air rod. The adjustment assembly includes multiple fixing bolts, each fixing bolt having a rotating rod rotatably embedded inside. Each rotating rod has an adjustment rod fixedly connected inside, and each adjustment rod has a pin fixedly connected inside. Each pin has a fixing groove fixedly connected to one side of its outer surface, and honeycomb sponge fixedly connected to the outer surface of its fixing groove. Each adjustment rod has a push groove on its outer surface. The cable tray has multiple round heads on both sides, and a displacement rod is fixedly connected to one side of the outer surface of each round head. A second piston is fixedly connected to the side of the displacement rod away from the round head, and a second air rod is slidably sleeved on the outer surface of the second piston.

[0006] Optionally, a motor is fixedly connected to one end of the outer surface of each of the plurality of rotating rods, and the output ends of the plurality of motors are fixedly connected to the rotating rods.

[0007] Optionally, the fixing frame is fixedly connected to one side of the outer surface of the honeycomb sponge, and the outer surfaces of the plurality of second air rods are fixedly connected with fixing grooves.

[0008] Optionally, an air supply pipe is fixedly connected inside the fixed frame, and an air bag is fixedly connected to the end of the air supply pipe away from the fixed frame.

[0009] Optionally, each of the first air rods has an air outlet fixedly connected inside, and a second spring is wound around the outer surface of the displacement rods.

[0010] Optionally, a first spring is wound around the outer surface of each of the plurality of movable rods, and one end of the plurality of first springs is fixedly connected to the clamping frame.

[0011] Optionally, each of the multiple second air rods has an air outlet pipe fixedly connected inside, and the end of the air outlet pipe away from the second air rod is fixedly connected inside the airbag.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. After the cable tray is installed by the workers, the motor is turned on, and the cable is placed inside the honeycomb sponge. The gas in the air chamber is supplied to the gas replenishment pipe through the gas supply pipe and the fixed frame. The gas replenishment pipe has a built-in one-way valve. The gas supply pipe is a flexible tube. The piston is pushed by the air rod. The piston pushes the clamping frame to clamp the cable through the moving rod. When displacement or angle adjustment is required, it prevents the cable from breaking during movement. The gas in the air rod is reset by the spring. The piston squeezes the gas and sprays it into the honeycomb sponge through the air outlet to dry the honeycomb sponge. When the spring drives the piston to reset, it squeezes the residual gas in the air rod and sprays it into the honeycomb sponge through the air outlet. The gas in the reset process is used to achieve drying. No additional power is required. It controls the humidity of the honeycomb sponge and the surface of the cable, and extends the service life of the cable insulation layer. Long-term moisture exposure of the cable can easily cause insulation layer aging, short circuit and leakage. The gas drying function continuously removes moisture, so as to stabilize the insulation resistance of the cable.

[0013] 2. By turning on the motor, the rotating rod rotates, which in turn adjusts the angle of the fixed slot via the adjusting rod. The fixed slot, in turn, adjusts the angle of the cable clamping angle via the honeycomb sponge. Simultaneously, the adjusting rod rotates the pusher slot, which squeezes the round head. The round head, via the displacement rod, drives the second piston to squeeze the air inside the second air rod. The air enters the air chamber through the air outlet pipe and is reset by the second spring. The second air rod has a built-in air inlet and a one-way valve, providing support for cables of different flatness. When clamping at a vertical angle, the pusher slot is not triggered to push the round head; the clamping frame is used for clamping. When tilted at different angles, the cable is supported by the mining equipment. As vibration increases, the round head is pushed and squeezed to inflate the airbag, which assists the clamping frame in clamping. This adapts to different heights and angles during underground mining, preventing cables from drooping off the cable tray due to fixing in the same direction, thus avoiding damage to the cables caused by crushing or blunt force during construction. The pin between the adjusting rod and the fixing groove prevents excessive local stress on the cable due to rigid adjustment. The motor drives the rotating rod to rotate, and through the linkage of the adjusting rod with the fixing groove and honeycomb sponge, the cable clamping angle can be adjusted from 0-45°, which can accurately adapt to the installation needs of large inclination angles, different layouts, and different heights underground.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1 to 5 The present invention provides a cable laying frame for underground mining, including a cable laying frame 1, a clamping component and an adjusting component inside the cable laying frame 1; The clamping assembly includes multiple first air rods 2, and each of the multiple first air rods 2 has a first piston 203 slidably embedded inside. Each of the multiple first pistons 203 has a moving rod 202 fixedly connected to its outer surface. Each of the multiple moving rods 202 has a clamping frame 201 fixedly connected to its side away from the first piston 203. Each of the multiple first air rods 2 has an air supply pipe 205 fixedly connected inside. Each of the air supply pipes 205 has a fixing frame 207 at its end away from the first air rod 2. The adjustment assembly includes multiple fixing bolts 3, and each fixing bolt 3 has a rotating rod 301 rotatably embedded inside. Each rotating rod 301 has an adjusting rod 302 fixedly connected inside, and each adjusting rod 302 has a pin 303 fixedly connected inside. Each pin 303 has a fixing groove 304 fixedly connected to one side of its outer surface, and each fixing groove 304 has a honeycomb sponge 305 fixedly connected to its outer surface. Each adjusting rod 302 has a push groove 306 on its outer surface. Each cable tray 1 has multiple round heads 307 on both sides, and each round head 307 has a displacement rod 311 fixedly connected to one side of its outer surface. The displacement rod 311 has a second piston 310 fixedly connected to the side away from the round head 307, and the second piston 310 has a second air rod 309 slidably sleeved on its outer surface.

[0018] Using the above technical solution, after the worker installs the cable tray 1, the motor 4 is turned on, and the cable is placed inside the honeycomb sponge 305. Gas from the airbag 5 is supplied to the replenishing air pipe 205 via the air supply pipe 208 and the fixing frame 207. The replenishing air pipe 205 has a built-in one-way valve. The air supply pipe 208 is a flexible hose. The air rod 2 pushes the piston 203, which in turn pushes the clamping frame 201 to clamp the cable via the moving rod 202. This prevents the cable from breaking during movement when displacement or angle adjustment is needed. The gas in the air rod 2 is reset by the spring 204. The gas squeezed by the plug 203 is sprayed into the honeycomb sponge 305 through the air outlet 206, drying the honeycomb sponge 305. When the spring 204 drives the piston 203 to reset, the residual gas in the squeeze rod 2 is sprayed directionally into the honeycomb sponge 305 through the air outlet 206. The drying is achieved by using the gas during the reset process without the need for additional power. This controls the humidity of the honeycomb sponge 305 and the surface of the cable, extending the service life of the cable insulation layer. Long-term exposure to moisture can easily lead to insulation layer aging, short circuits, and leakage. The gas drying function continuously removes moisture, stabilizing the insulation resistance of the cable.

[0019] Through the above technical solution, by turning on the motor 4, the rotating rod 301 is driven to rotate. The rotating rod 301 drives the fixing groove 304 to adjust the angle via the adjusting rod 302. The fixing groove 304 drives the honeycomb sponge 305 to adjust the angle of cable clamping. At the same time, the adjusting rod 302 drives the push groove 306 to rotate. The push groove 306 squeezes the round head 307. The round head 307 drives the second piston 310 to squeeze the air inside the second air rod 309 via the displacement rod 311. The air enters the airbag 5 through the air outlet pipe 312 and is reset by the second spring 308. The second air rod 309 has a built-in air inlet and a one-way valve to support cables of different flatness. When clamping at a vertical angle, the push groove 306 is not triggered to push the round head 307, and the clamping is achieved by the clamping frame 201. When tilted at different angles, the impact of vibration from mining equipment increases. At this time, push 306 to squeeze the round head 307 to inflate the airbag 5, and assist the clamping frame 201 to clamp it. This adapts to different heights and angles during underground mining and prevents the cable from drooping out of the cable laying frame 1 due to fixing in the same direction, which would affect underground mining construction or cause damage to the cable due to crushing or blunt force during construction. The pin 303 between the adjusting rod 302 and the fixing groove 304 prevents the cable from being subjected to excessive local stress due to rigid adjustment. The motor 4 drives the rotating rod 301 to rotate. Through the linkage of the adjusting rod 302 with the fixing groove 304 and the honeycomb sponge 305, the cable clamping angle can be adjusted from 0 to 45°, which can accurately adapt to the installation requirements of large inclination angles, different layouts, and different heights underground.

[0020] Specifically, a motor 4 is fixedly connected to one end of the outer surface of each of the multiple rotating rods 301, and the output ends of the multiple motors 4 are fixedly connected to the rotating rods 301.

[0021] Through the above technical solution, the rotating rod 301 is driven to rotate by the motor 4, thereby achieving multi-angle differential adjustment.

[0022] Specifically, the fixing bracket 207 is fixedly connected to one side of the outer surface of the honeycomb sponge 305, and the outer surfaces of the multiple second air rods 309 are fixedly connected with fixing grooves 101.

[0023] The honeycomb sponge 305 is fixed by the fixing bracket 207 through the above technical solution.

[0024] Specifically, an air supply pipe 208 is fixedly connected inside the fixed frame 207, and an airbag 5 is fixedly connected to the end of the air supply pipe 208 away from the fixed frame 207.

[0025] Through the above technical solution, gas is delivered to the airbag 5 via the gas delivery pipe 208.

[0026] Specifically, each of the multiple first air rods has an air outlet 206 fixedly connected inside, and the outer surface of the multiple displacement rods 311 is wrapped with a second spring 308.

[0027] Through the above technical solution, gas is injected through the air outlet 206 to dry the cable and honeycomb sponge 305, and the displacement rod 311 is reset by the second spring 308.

[0028] Specifically, a first spring 204 is wound around the outer surface of each of the multiple moving rods 202, and one end of each first spring 204 is fixedly connected to the clamping frame 201.

[0029] The above technical solution uses spring 204 to buffer the clamping force and automatically reset, preventing cable damage.

[0030] Specifically, each of the multiple second air springs 309 has an air outlet pipe 312 fixedly connected inside, and the end of the air outlet pipe 312 away from the second air spring 309 is fixedly connected inside the airbag 5.

[0031] Through the above technical solution, the second air rod 309 is supplied with air through the air outlet pipe 312.

[0032] During use, after the cable tray 1 is installed by the worker, the motor 4 is turned on, and the cable is placed inside the honeycomb sponge 305. The gas in the airbag 5 is supplied to the air replenishment pipe 205 through the air supply pipe 208 and the fixing frame 207. The air replenishment pipe 205 has a built-in one-way valve. The air supply pipe 208 is a flexible hose. The piston 203 is pushed by the air rod 2, and the piston 203 pushes the clamping frame 201 to clamp the cable through the moving rod 202. When displacement or angle adjustment is required, it prevents the cable from breaking during movement. The gas in the air rod 2 is reset by the spring 204, and the piston 2... 03. The compressed gas is sprayed into the honeycomb sponge 305 through the air outlet 206 to dry the honeycomb sponge 305. When the spring 204 drives the piston 203 to reset, the residual gas in the compressed air rod 2 is sprayed into the honeycomb sponge 305 through the air outlet 206. The drying is achieved by using the gas during the reset process without the need for additional power. The humidity of the honeycomb sponge 305 and the cable surface is controlled, which extends the service life of the cable insulation layer. Long-term exposure to moisture can easily lead to insulation layer aging, short circuit and leakage. The gas drying function continuously removes moisture, making the cable insulation resistance stable.

[0033] By activating motor 4, the rotating rod 301 is driven to rotate. The rotating rod 301, through adjusting rod 302, drives the fixing groove 304 to adjust its angle. The fixing groove 304, in turn, drives the honeycomb sponge 305 to adjust the angle of cable clamping. Simultaneously, adjusting rod 302 drives pushing groove 306 to rotate, which in turn compresses round head 307. Round head 307, through displacement rod 311, drives second piston 310 to compress air inside second air rod 309. The air enters airbag 5 through air outlet pipe 312 and is reset by second spring 308. Second air rod 309 has a built-in air inlet and one-way valve to support cables of different flatness. When clamping at a vertical angle, pushing groove 306 is not triggered to push round head 307; clamping is achieved by clamping frame 201. When tilted at the same angle, the impact of vibration from the mining equipment increases. At this time, push 306 to squeeze the round head 307 to inflate the airbag 5 and assist the clamping frame 201 in clamping. This adapts to different heights and angles during underground mining and prevents the cable from drooping out of the cable laying frame 1 due to fixing in the same direction, which would affect underground mining construction or cause damage to the cable due to crushing or blunt force during construction. The pin 303 between the adjusting rod 302 and the fixing groove 304 prevents the cable from being subjected to excessive local stress due to rigid adjustment. The motor 4 drives the rotating rod 301 to rotate. Through the linkage of the adjusting rod 302 with the fixing groove 304 and the honeycomb sponge 305, the cable clamping angle can be adjusted from 0 to 45°, which can accurately adapt to the installation requirements of large inclination angles, different layouts, and different heights underground.
