Description

Technical Field

[0001] This invention relates to the field of mine transportation equipment technology, and in particular to a derailment prevention detection system for inclined shaft transport vehicles. Background Technology

[0002] In mines, equipment and goods are generally transported by transport vehicles along underground mine tracks. Flatbed trucks, for example, do not have their own power and need to be towed by a tractor. The flatbed truck is moved along the track by being dragged or pulled by the tractor.

[0003] When a transport vehicle is pulled by a traction rope on a track, the traction rope may break due to prolonged use or excessive load. If the traction rope breaks, the transport vehicle located on a slope will lose control of its speed, causing it to rush down the slope to the bottom of the mine, resulting in casualties and property damage. Summary of the Invention

[0004] This application provides a derailment prevention detection system for inclined shaft transport vehicles. This solves the problem in the prior art where the traction rope may break due to excessive load when the transport vehicle is being pulled along the track. If the traction rope breaks, the transport vehicle on the slope will lose speed control, causing it to plunge down the slope to the bottom of the mine, resulting in casualties and property damage. The system ensures that if the traction rope breaks while the transport vehicle is moving down the slope within the mine, the transport vehicle can be stopped on the track, preventing casualties and property damage.

[0005] This application provides a derailment prevention detection system for a sloping shaft transport vehicle, including a conveying assembly. The conveying assembly includes a carriage, a guide rail, a traction rope, and a moving wheel. The traction rope is used to pull the carriage to move on the guide rail, and the moving wheel is in contact with the guide rail.

[0006] It also includes braking components;

[0007] The braking assembly includes a protective shell, a cable, a controller, a fixing plate, a retractor, a braking block, a signal transmitting block, and a signal receiving block;

[0008] The protective shell is fixed to the bottom of the carriage, and a winding machine is fixed inside the protective shell. One end of the cable is wound around the shaft of the winding machine.

[0009] The controller is located on one side of the protective shell and is fixed to the bottom of the carriage;

[0010] Two fixed plates are slidably connected to the bottom of the carriage;

[0011] The fixing plate is located on the outside of the two tracks, and the other end of the cable is fixedly connected to the fixing plate.

[0012] Multiple brake blocks are fixed on the fixed plate, and the brake blocks are located between the fixed plate and the guide rail;

[0013] The signal transmitting block is fixed on the fixing plate, and the signal transmitting block is located between the braking blocks;

[0014] The guide rail has a groove, and the signal receiving block is fixed in the groove.

[0015] Furthermore, a fixing block is fixedly connected to the bottom of the carriage;

[0016] The fixing block has a circular hole through which the traction rope passes, and the fixing block can fix the traction rope to the bottom of the carriage.

[0017] Furthermore, the signal receiving block is a photosensitive receiving tube;

[0018] Multiple signal receiving blocks are fixed on the guide rail, and the signal receiving blocks are spaced at the same distance.

[0019] The signal transmitting block is an infrared emitting tube;

[0020] Two signal transmitting blocks are fixed on the mounting plate.

[0021] Furthermore, the fixing block is a rectangular block;

[0022] A fixing bolt is fixedly connected to the fixing block;

[0023] The fixing bolt is a bolt rod, and the bottom of the fixing bolt is in contact with the traction rope;

[0024] The fixing bolt is threaded to the bottom of the fixing block.

[0025] Furthermore, a slide rail is fixed to the bottom of the carriage, and the controller is fixed to the bottom of the carriage by the slide rail;

[0026] The slide rail consists of two L-shaped plates;

[0027] The slide rail is fixed to the bottom of the carriage by bolts.

[0028] Furthermore, the winding machine is a dual-head motor;

[0029] The cable is fixed and wound around the shaft of the winding machine;

[0030] The cable is composed of multiple nylon ropes wound together.

[0031] Furthermore, a support frame is fixed to the bottom of the carriage, and the movable wheels are rotatably connected to the support frame;

[0032] The support frame leaves a gap between the moving wheels and the bottom of the carriage;

[0033] The support frame is a rectangular plate.

[0034] Furthermore, the braking block is a plurality of rectangular blocks;

[0035] A rubber pad is fixed on the contact surface between the brake block and the guide rail.

[0036] Furthermore, the guide rail consists of two parallel I-beams.

[0037] Furthermore, the traction rope is composed of multiple steel wire ropes wound together;

[0039] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0040] The signal transmitted by the signal transmitting block is received by the signal receiving block. The signal receiving blocks are spaced at the same interval. When the transport vehicle moves at a constant speed, the signal receiving blocks receive signals at the same interval. When the traction rope breaks, the transport vehicle loses speed control. After receiving the signal, the controller controls the winding machine to run. The brake block contacts the guide rail to stop the transport vehicle. This effectively solves the problem in the existing technology where the transport vehicle loses speed control after the traction rope breaks, causing the transport vehicle to rush down the slope to the bottom of the mine, resulting in casualties and property damage. This technology enables the transport vehicle to stop on the track when it slides down. Attached Figure Description

[0052] like Figures 1 to 6 As shown, this application proposes an anti-derailment detection system for a sloping shaft transport vehicle, including a conveying assembly 100. The conveying assembly 100 includes a carriage 101, a guide rail 102, a traction rope 104, and a moving wheel 107. The traction rope 104 is driven by a motor and is used to pull the carriage 101 to move on the guide rail 102. The moving wheel 107 contacts the guide rail 102 and rolls on the guide rail 102.

[0053] It also includes a braking assembly 200; the braking assembly 200 includes a protective shell 201, a cable 202, a controller 204, a fixing plate 205, a winder 206, a braking block 207, a signal transmitting block 208, and a signal receiving block 209;

[0054] The protective shell 201 is fixed to the bottom of the carriage 101. The winding machine 206 is fixed inside the protective shell 201. The protective shell 201 protects the winding machine 206. One end of the cable 202 is wound around the shaft of the winding machine 206. The winding machine 206 drives the cable 202 to move.

[0055] The controller 204 is located on one side of the protective shell 201 and is fixed to the bottom of the carriage 101. The controller 204 can receive signals from the signal receiving module and control the winding machine 206 to run according to the signals from the signal receiving module.

[0056] Two fixed plates 205 are slidably connected to the bottom of the carriage 101; the fixed plates 205 are located on the outside of the two rails, and the other end of the cable 202 is fixedly connected to the fixed plates 205; multiple brake blocks 207 are fixed on the fixed plates 205, and the brake blocks 207 are located between the fixed plates 205 and the guide rail 102. The cable 202 pulls the fixed plates 205 to move to the guide rail 102, so that the brake blocks 207 on the guide rail 102 contact the guide rail 102, thereby stopping the carriage 101 on the guide rail 102;

[0057] The signal transmitting block 208 is fixed on the fixed plate 205 and is located between the brake blocks 207. The signal transmitting block 208 continuously transmits signals when the transport vehicle moves. The guide rail 102 has a groove, and the signal receiving block 209 is fixed in the groove. The signal receiving block 209 receives the signal emitted by the signal transmitting block 208 and judges the moving speed of the transport vehicle according to the frequency of the received signal. The order of the signals received by different signal receiving blocks 209 determines the moving direction of the transport vehicle.

[0058] Preferably, a fixing block 105 is fixedly connected to the bottom of the carriage 101; the fixing block 105 has a round hole, through which the traction rope 104 passes. After passing through the fixing block 105, the traction rope 104 is knotted at the end. The fixing block 105 can fix the traction rope 104 to the bottom of the carriage 101, which can prevent the traction rope 104 from falling off when the carriage 101 is moved, and at the same time facilitate the replacement of the traction rope 104.

[0059] Preferably, the signal receiving block 209 is a photosensitive receiving tube, which can receive infrared light signals emitted by the signal transmitting block 208; multiple signal receiving blocks 209 are fixed on the guide rail 102, and the signal receiving blocks 209 are spaced at the same distance. The moving direction and speed of the carriage 101 are determined by the frequency and order of the signals received by the signal receiving blocks 209; the signal transmitting block 208 is an infrared emitting tube; two signal transmitting blocks 208 are fixed on the fixing plate 205. When the moving direction of the transport vehicle changes, two signal receiving blocks 209 will repeatedly receive the signals sent by the signal transmitting blocks 208. The controller 204 controls the winding machine 206 according to the signals received by the signal receiving blocks 209.

[0060] Preferably, the controller 204 is equipped with a wireless transmission module, and the signal receiving block 209 is equipped with a signal transmitting module. The signal receiving block 209 transmits the received signal to the controller 204.

[0061] Preferably, the signal receiving block 209 is located at the bottom of the groove on the side wall of the guide rail 102, and the braking block 207 will not touch the signal receiving block 209 when it contacts the side wall of the guide rail 102.

[0062] Preferably, the wireless transmission module on the controller 204 is a Bluetooth module. The Bluetooth module on the controller 204 can connect to multiple Bluetooth modules at the same time. The signal receiving block 209 also has a Bluetooth module. The signal sent by the Bluetooth module on each signal receiving block 209 has a different code when received by the Bluetooth module on the controller 204, thereby enabling the controller 204 to determine the direction and speed of the carriage 101.

[0063] Preferably, the fixing block 105 is a rectangular block; a fixing bolt 106 is fixedly connected to the fixing block 105; the fixing bolt 106 is a bolt rod, and the bottom of the fixing bolt 106 contacts the traction rope 104; the fixing bolt 106 is threadedly connected to the bottom of the fixing block 105, and the traction rope 104 is firmly fixed to the fixing block 105 when the fixing bolt 106 is tightened, so as to prevent the traction rope 104 from falling off when the carriage 101 is pulled to move.

[0064] Preferably, a slide rail 203 is fixed to the bottom of the carriage 101, and the controller 204 is fixed to the bottom of the carriage 101 by the slide rail 203; the slide rail 203 consists of two L-shaped plates; the slide rail 203 is fixed to the bottom of the carriage 101 by bolts.

[0065] Preferably, the winder 206 is a dual-head motor; the cable 202 is fixed and wound around the shaft of the winder 206; the cable 202 is composed of multiple nylon ropes wound together, and a spring is provided at the sliding connection between the fixing plate 205 and the bottom of the carriage 101. When the carriage 101 resumes normal driving, the winder 206 rotates in the opposite direction to release the cable 202, and the cable 202 is straightened under the action of the spring, while the fixing plate 205 is reset.

[0066] Preferably, when the winding machine 206 tightens the cable 202, if the carriage 101 still slides down the inclined guide rail 102 at too high a speed, the winding machine 206 can apply pressure to the brake block 207 on the fixed plate 205 by tightening the traction rope 104, thereby increasing the friction between the brake block 207 and the guide rail 102, so that the sliding speed of the carriage 101 is controlled, and the carriage 101 is gradually stopped on the guide rail 102, thus avoiding the carriage 101 from sliding down too fast and losing control.

[0067] Preferably, a support frame 103 is fixed to the bottom of the carriage 101, and the movable wheel 107 is rotatably connected to the support frame 103; the support frame 103 leaves a gap between the movable wheel 107 and the bottom of the carriage 101.

[0068] Preferably, the support frame 103 is a rectangular plate.

[0069] Preferably, the brake block 207 is a plurality of rectangular blocks; a rubber pad is fixed on the contact surface between the brake block 207 and the guide rail 102, the rubber pad can increase the friction between the brake block 207 and the guide rail 102, and the carriage 101 can be stopped quickly when the brake block 207 and the guide rail 102 are in contact.

[0070] Preferably, the rubber pads fixed on the brake block 207 are glued and fixed on the brake block 207. Each time the brake block 207 brakes the carriage 101, a new rubber pad needs to be glued on to ensure that the brake block 207 can maintain a good braking effect and stop the carriage 101 on the guide rail 102 when the carriage 101 slides up and down the guide rail 102.

[0071] Preferably, the guide rail 102 consists of two parallel I-shaped rods.

[0072] Preferably, the traction rope 104 is composed of multiple steel wire ropes wound together; the other end of the traction rope 104 is fixed and wound around the motor that pulls the traction rope 104, and the motor pulls the traction rope 104, thereby driving the carriage 101 to move on the inclined guide rail 102.

[0073] In practical use, a derailment prevention detection system for a sloping shaft transport vehicle according to an embodiment of this application is as follows:

[0074] The traction rope 104 pulls the carriage 101 to move on the inclined guide rail 102. The signal transmitting block 208 continuously sends signals, and the signal receiving block 209 transmits the received signals to the controller 204. When the traction rope 104 breaks, the carriage 101 will slide into the mine along the guide rail 102. When the direction of movement of the carriage 101 changes, the two signal receiving blocks 209 will repeatedly receive the signals sent by the signal transmitting block 208. After receiving this signal, the controller 204 controls the winding machine 206 to run. The winding machine 206 winds the cable 202 onto the shaft of the winding machine 206. The cable 202 pulls the fixing plate 205 to move towards the guide rail 102. The brake block 207 located on the fixing plate 205 fits against the side wall of the guide rail 102, stopping the carriage 101 from sliding downwards, and thus fixing the carriage 101 on the guide rail 102.

[0075] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
