[0002] With the progress of science and technology, fully mechanized mining equipment is more and more advanced, and the moving and transporting equipment of large equipment such as coal mining machine and hydraulic support is also various. For the inclined shaft (tunnel), the large equipment of the working face has monorail hoist transportation, track flat car transportation and trackless rubber tire support carrier transportation, and the above transportation methods are divided into integral transportation and disintegration transportation. In underground mining operations such as coal mines, hydraulic supports are mainly used to support and control the roof of the coal mining working face, and are the key equipment of underground coal mining. Because of its large size and heavy weight, the auxiliary transportation channel between the underground and the ground, the auxiliary inclined shaft, undertakes the task of transporting the hydraulic support to the underground working position.

[0009] The beneficial effect of the above further scheme is that, by installing the first motor, when the first motor works, the winch is driven to rotate, so that the winding and unwinding of the first steel wire rope provided outside the winch is realized, when the first steel wire rope is wound, the heavy vehicle assembly approaches the pneumatic car stop under the cooperation of the hoist assembly, and when the first steel wire rope is unwound, the heavy vehicle assembly constantly moves away from the pneumatic car stop under the cooperation of the hoist assembly.

[0010] Further, the inside of the support base is rotatably connected with a winch, the outside of the winch is provided with a first steel wire rope, one end of the first steel wire rope passes through a fixed pulley assembly and is connected with the outer wall of the second pin shaft close to the upper end, the front of the support base is provided with a first motor, and the output end of the first motor is in transmission connection with the winch.

[0011] The beneficial effect of the above further scheme is that, by installing the first motor, when the first motor works, the winch is driven to rotate, so that the winding and unwinding of the first steel wire rope provided outside the winch is realized, when the first steel wire rope is wound, the heavy vehicle assembly approaches the pneumatic car stop under the cooperation of the hoist assembly, and when the first steel wire rope is unwound, the heavy vehicle assembly constantly moves away from the pneumatic car stop under the cooperation of the hoist assembly.

[0012] Further, one pair of the steel rails provided on the side away from the mounting base is provided with a secondary inclined shaft, the fixed pulley assembly comprises a fixed frame, the fixed frame is arranged on one side of the secondary inclined shaft, and the inside of the fixed frame is rotatably connected with a fixed pulley, the outside of the fixed pulley is provided with a groove, and the inner wall of the groove is in clearance fit with the outer wall of the first steel wire rope.

[0013] The beneficial effect of the above further scheme is that, the fixed frame is installed on the non-pedestrian side of the mouth of the secondary inclined shaft, by arranging the fixed pulley and the groove on the outside of the fixed pulley, the first steel wire rope is guided and supported by the fixed pulley during the winding and unwinding of the first steel wire rope.

[0014] Furthermore, the outer walls of the first and second pins are respectively clearance-fitted with the inner walls of the two openings, and the first and second pins are both provided with limiting holes. The limiting holes are provided with limiting rods inside, and the inner walls of the limiting holes are provided with internal threads. The limiting rods are provided with external threads, and the internal threads and external threads are engaged with each other.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the limiting hole, internal thread, limiting rod and external thread, the limiting rod is threadedly connected to the limiting hole, so that the first pin and the second pin are limited and fixed in the opening, thus preventing the first pin and the second pin from accidentally separating from the opening.

[0016] Furthermore, the upper end of the movable base is connected to the bottom end of the fixed base, and a pair of connecting rods are rotatably connected inside the movable base. Both ends of the pair of connecting rods extend through the movable base to the outside and are connected to rollers.

[0017] Furthermore, the roller has an H-shaped longitudinal section, and the bottom end of the roller is in contact with the upper end of the rail. The two sides of the inner wall of the roller at the bottom end are in contact with the two sides of the outer wall of the rail near the upper end.

[0018] The beneficial effect of adopting the above-mentioned further solution is that, since the longitudinal section of the roller is H-shaped, it ensures that the heavy vehicle assembly can remain stable during operation, reducing the risk of displacement.

[0019] Compared with existing technologies, the beneficial effects of this utility model are as follows: The coal mine utilizes a heavy-load vehicle forward and lowering device. The disassembled hydraulic support is placed on a fixed base, and a special vehicle sealer is used in conjunction with a wire rope to seal the vehicle. Then, the first and second motors are started respectively, causing the winch to wind up the first wire rope and the drum to unwind the second wire rope, enabling the entire heavy-load vehicle assembly to continuously advance and lower towards the auxiliary inclined shaft opening on the rails. The operation of the winch assembly drives the heavy-load vehicle assembly to slowly advance and lower, reducing the intensity of manual pushing and improving transportation efficiency. Furthermore, a pneumatic vehicle stopper, using compressed air as a power source, allows compressed air to enter the cylinder when it is necessary to stop the heavy-load vehicle assembly. The piston inside the cylinder moves under air pressure. The movement of the piston drives the connecting rod and other transmission mechanisms, causing the pneumatic brake's pawl to rise, thereby blocking the roller and preventing the heavy vehicle assembly from moving forward. This keeps the entire heavy vehicle assembly at the entrance of the auxiliary inclined shaft, where the hydraulic support is transferred. When it is time to release the heavy vehicle assembly, the control valve is operated to release the gas in the cylinder. The piston returns to its original position under the action of the reset device, the pawl falls down, and then the limit rod at the second pin is unscrewed, and the second pin is removed from the opening. Then, the buckle of the wire rope on the hoist inside the auxiliary inclined shaft is fastened to the opening of the second connecting plate, and the heavy vehicle assembly is then transported by the auxiliary inclined shaft hoist to the designated position in the shaft.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5This utility model provides a technical solution: a coal mine heavy vehicle forward and lowering device, including a base assembly 100, a winch assembly 300, a fixed pulley assembly 400, and a hoist assembly 500. The base assembly 100 includes a pneumatic car stopper 1001, with steel rails 1002 installed on both sides of the upper end of the pneumatic car stopper 1001. A heavy vehicle assembly 200 is slidably mounted on the base assembly 100. The heavy vehicle assembly 200 includes a movable base 2001 and a fixed base 2002. A first connecting plate 2003 and a second connecting plate 2004 are respectively installed on both sides of the fixed base 2002. The first connecting plate 2003 and the second connecting plate 2004 each have openings 2005 inside, and a first pin 2006 and a second pin 2007 are provided inside each of the two openings 2005. The winch assembly 300... The hoist assembly 500 includes a support base 3001 located on the back of one of the rails 1002. The hoist assembly 500 includes a mounting base 5001 located on one side of a pair of rails 1002. By setting a pneumatic brake 1001, compressed air is used as a power source. When it is necessary to stop the heavy vehicle assembly 200, the control device allows compressed air to enter the cylinder. The piston in the cylinder moves under the action of air pressure. The movement of the piston drives the connecting rod and other transmission mechanisms, causing the pawl of the pneumatic brake 1001 to rise, thereby blocking the roller 2010 and preventing the heavy vehicle assembly 200 from continuing to move forward. When it is necessary to release the heavy vehicle assembly 200, the control valve is operated to discharge the gas in the cylinder. The piston returns to its original position under the action of the reset device, and the pawl falls down, so that the heavy vehicle assembly 200 can continue to move forward.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5This utility model provides a technical solution: a winch 3002 is rotatably connected inside a support base 3001, and a first steel wire rope 3003 is wound around the outside of the winch 3002. One end of the first steel wire rope 3003 passes through a fixed pulley assembly 400 and is connected to the outer wall of a second pin 2007 near its upper end. A first motor 3004 is mounted on the front of the support base 3001, and the output end of the first motor 3004 is connected to the winch 3002 via a transmission connection. A drum 5002 is rotatably connected inside a mounting base 5001, and a second steel wire rope 500 is wound around the outside of the drum 5002. 3. A three-ring chain 5004 is installed at one end of the second wire rope 5003. The end of the three-ring chain 5004 away from the second wire rope 5003 is sleeved on the outside of the first pin 2006. The top and bottom surfaces of the three-ring chain 5004 at the end away from the second wire rope 5003 abut against the bottom surface of the first pin 2006 near the upper end and the top surface of the first connecting plate 2003, respectively. A second motor 5005 is installed on the front of the mounting base 5001. The output end of the second motor 5005 is connected to the drum 5002 for transmission. A pair of rails 1002 are provided on the side away from the mounting base 5001. The system includes a secondary inclined shaft. A fixed pulley assembly 400 includes a fixed frame 4001, which is located on one side of the secondary inclined shaft. A fixed pulley 4002 is rotatably connected inside the fixed frame 4001. The fixed pulley 4002 has a groove on its outer surface, and the inner wall of the groove is clearance-fitted with the outer wall of the first wire rope 3003. Starting the first motor 3004 and the second motor 5005 causes the winch 3002 to wind up the first wire rope 3003 and the drum 5002 to unwind the second wire rope 5003, thus enabling the entire heavy vehicle assembly 200 to continuously move forward on the rail 1002 towards the opening of the secondary inclined shaft. The lowering process involves the winch assembly 300 driving the heavy car assembly 200 forward and lowering it slowly, reducing the intensity of manual pushing and improving transportation efficiency. When the heavy car assembly 200 is lifted from the bottom yard to the entrance of the auxiliary inclined shaft by the hoisting machine, the first motor 3004 and the second motor 5005 are restarted, causing the winch 3002 to unwind the first wire rope 3003 and the drum 5002 to wind up the second wire rope 5003. This allows the entire heavy car assembly 200 to be continuously lifted away from the entrance of the auxiliary inclined shaft on the rail 1002 and in the main transport roadway and the track uphill roadway.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5This utility model provides a technical solution: the outer walls of the first pin 2006 and the second pin 2007 are respectively clearance-fitted with the inner walls of the two openings 2005, and the first pin 2006 and the second pin 2007 are both provided with limit holes. A limit rod 2008 is provided inside the limit hole, and the inner wall of the limit hole is provided with an internal thread. The outer side of the limit rod 2008 is provided with an external thread, and the internal thread and the external thread are engaged. The upper end of the movable base 2001 is connected to the bottom end of the fixed base 2002, and a pair of connecting rods 2009 are rotatably connected inside the movable base 2001. Both ends of the pair of connecting rods 2009 extend through the movable base 2001 to the outside and are connected to rollers 2010. The longitudinal section of roller 2010 is H-shaped, and the bottom end of roller 2010 is in contact with the upper end of rail 1002. The inner walls of roller 2010 at the bottom end are in contact with the outer walls of rail 1002 near the upper end. When the heavy vehicle assembly 200 moves to the opening of the auxiliary inclined shaft, the limiting rod 2008 at the second pin 2007 is unscrewed, and the second pin 2007 is taken out from the opening 2005. Then, the buckle of the wire rope on the hoist inside the auxiliary inclined shaft is fastened to the opening 2005 of the second connecting plate 2004. The heavy vehicle assembly 200 is then transported by the auxiliary inclined shaft hoist to the designated position in the shaft. Because the longitudinal section of roller 2010 is H-shaped, it ensures that the heavy vehicle assembly 200 can remain stable during operation and reduces the risk of displacement.

[0032] Specifically, the working principle of this type of coal mine heavy vehicle forward and lowering equipment is as follows: During use, the disassembled hydraulic support is placed on the fixed base 2002, and a special sealing device is used in conjunction with a wire rope to seal the vehicle. Then, the first motor 3004 and the second motor 5005 are started, causing the winch 3002 to wind up the first wire rope 3003 and the drum 5002 to unwind the second wire rope 5003, thus enabling the entire heavy vehicle assembly 200 to continuously advance and lower itself towards the auxiliary inclined shaft opening on the rail 1002. The operation of the winch assembly 300 drives the heavy vehicle assembly 200 forward and downward slowly, reducing the workload of manual pushing and improving transportation efficiency. By setting up a pneumatic wheel stopper 1001, using compressed air as a power source, when it is necessary to stop the heavy vehicle assembly 200, the control device allows compressed air to enter the cylinder. The piston inside the cylinder moves under the action of air pressure. The movement of the piston drives the connecting rod and other transmission mechanisms, causing the pawl of the pneumatic wheel stopper 1001 to rise, thereby blocking the roller 2010. To prevent the heavy vehicle assembly 200 from advancing further, it is positioned at the entrance of the auxiliary inclined shaft. The limiting rod 2008 at the second pin 2007 is unscrewed, and the second pin 2007 is removed from the opening 2005. Then, the clip of the wire rope on the hoist inside the auxiliary inclined shaft is fastened to the opening 2005 of the second connecting plate 2004. The control valve is operated to release the gas in the cylinder. The piston returns to its original position under the action of the reset device, the stop pawl falls, and the heavy vehicle assembly 200 is then... The auxiliary inclined shaft hoist transports the vehicle to the designated location underground. When the heavy vehicle assembly 200 is lifted from the bottom yard to the entrance of the auxiliary inclined shaft by the hoist, the first motor 3004 and the second motor 5005 are started again. This causes the winch 3002 to unwind the first wire rope 3003 and the drum 5002 to wind up the second wire rope 5003, thus enabling the entire heavy vehicle assembly 200 to be continuously lifted on the rail 1002 away from the entrance of the auxiliary inclined shaft and in the transport roadway and the track incline.
