Description

Technical Field

[0001] The present application relates to the field of mining transport vehicles, and in particular to a side-discharging mining double-headed rubber-wheeled transport vehicle. Background Art

[0002] Rubber-wheeled transport vehicles are the main auxiliary transport vehicles in coal mines. They can transport coal, slag and other items in the mine to the ground, and can also transport personnel, equipment or materials required for mining from the ground to various work points underground.

[0003] At present, most of the rubber-wheeled transport vehicles used in coal mines are usually composed of a frame, a cab and a hopper. The cab is set on one side of the frame, and the hopper is set on the frame to place materials. A discharge door is set on the side of the hopper away from the cab, and a cylinder is set on the bottom of the hopper near the cab. When unloading, the cylinder extends, lifts one end of the hopper, opens the discharge door, and the material slides down the inclined hopper to the rear of the transport vehicle to complete the unloading.

[0004] However, due to the narrow mine tunnels, the hopper usually extends from the direction close to the cab to the direction away from the cab. When unloading, the hopper usually needs to be lifted to a higher height so that the materials can slide down, which has high requirements for the height of the mine. The height of some mines does not meet the requirements, so workers are needed to assist in unloading, and the applicability is poor. Summary of the invention

[0005] In order to facilitate the unloading of rubber-wheeled transport vehicles in low and narrow tunnels and improve their applicability, the present application provides a side-unloading mining double-headed rubber-wheeled transport vehicle.

[0006] The present application provides a side-discharging mining double-headed rubber-wheeled transport vehicle, which adopts the following technical solution: A side-unloading mining double-headed rubber-wheeled transport vehicle comprises a vehicle body, the vehicle body comprises a cab, a frame and a material transport bin, the cab is arranged at one end of the frame, the material transport bin is arranged on the top of the frame and is located on one side of the cab, and also comprises a driving assembly and a unloading assembly, the material transport bin is provided with an unloading door on one side along the driving direction of the vehicle body, a bearing plate is provided at the bottom of the material transport bin, a storage groove for accommodating the unloading door is provided on the frame, the driving assembly is arranged on the frame, and drives the unloading door to move into or out of the storage groove; the unloading assembly is arranged on the frame, and when the unloading door moves into the storage groove, the unloading assembly drives the bearing plate to rise away from the end of the unloading door, and when the unloading door moves out of the storage groove, the unloading assembly drives the bearing plate to descend away from the end of the unloading door.

[0007] By adopting the above technical solution, when the vehicle body runs to the designated unloading location in the lane, the driving component drives the unloading door to move into the storage slot, and the unloading component will lift the side of the load plate away from the unloading door, so that the load plate is in an inclined state, and the goods can slide along the load plate to the ground to complete the unloading. Since the unloading door is set in the length direction of the load plate, the goods can slide down by lifting it to a lower height, and unloading can be completed even in a lane with a lower height, which improves the applicability of the rubber-wheeled transport vehicle.

[0008] Optionally, the unloading assembly includes a control telescopic rod and an articulated telescopic rod, the fixed end of the control telescopic rod is fixedly connected to the inner bottom wall of the storage groove, the movable end of the control telescopic rod is fixedly connected to the bottom of the unloading door, the articulated telescopic rod is arranged on the material transport bin and is located at the end of the material transport bin away from the unloading door, and a hinge hole for accommodating the movable end of the articulated telescopic rod is opened on the side wall of the supporting plate, and the movable end of the articulated telescopic rod is embedded in the hinge hole. When the articulated telescopic rod is retracted, the supporting plate can be rotatably connected to the material transport bin, and the rodless cavity of the control telescopic rod is communicated with the rod cavity of the articulated telescopic rod.

[0009] By adopting the above technical scheme, during the transportation process, the movable end of the articulated telescopic rod is embedded in the articulated hole, and the load-bearing plate is stably fixed to the bottom of the transport bin to ensure the stability of transportation; when unloading, the driving component drives the unloading door to move into the storage groove, squeezes the control telescopic rod to shrink it, and controls the medium in the rodless cavity of the telescopic rod to enter the rod cavity of the articulated telescopic rod, driving the articulated telescopic rod to shrink, and the movable end of the articulated telescopic rod withdraws from the articulated hole. At this time, lift the end of the load-bearing plate away from the unloading door, and the goods can slide along the load-bearing plate. By controlling the opening and closing state of the unloading door, the load-bearing plate can be automatically fixed or unlocked, making the unloading more automated and saving time and effort.

[0010] Optionally, the unloading assembly also includes a lifting telescopic rod, which is arranged on a side of the bottom of the loading plate away from the unloading door, the fixed end of the lifting telescopic rod is fixedly connected to the frame, the movable end of the lifting telescopic rod is hinged with a connecting block, the connecting block is slidably connected to the bottom of the loading plate, and the rod cavity of the articulated telescopic rod is connected to the rodless cavity of the lifting telescopic rod.

[0011] By adopting the above technical scheme, when the driving component drives the unloading door to be retracted into the storage groove, the medium in the rodless cavity of the control telescopic rod is pressed into the rod cavity of the hinged telescopic rod, driving the hinged telescopic rod to contract, and the movable end of the hinged telescopic rod is withdrawn from the hinge hole. Then the unloading door continues to move downward, and the medium in the rodless cavity of the control telescopic rod enters the rodless cavity of the lifting telescopic rod through the rod cavity of the hinged telescopic rod, driving the lifting telescopic rod to extend, and lifting the end of the load-bearing plate away from the unloading door. The unloading process does not require manual operation, which is convenient and labor-saving.

[0012] Optionally, a first overflow valve is arranged between the rodless cavity of the control telescopic rod and the rod cavity of the articulated telescopic rod, the rodless cavity of the lifting telescopic rod is connected with the rodless cavity of the control telescopic rod through a one-way valve, the one-way valve is used to control the medium in the rodless cavity of the lifting telescopic rod to enter the rodless cavity of the control telescopic rod, and a second overflow valve is arranged between the rod cavity of the articulated telescopic rod and the rodless cavity of the lifting telescopic rod.

[0013] By adopting the above technical solution, after unloading is completed, the driving component drives the unloading door to move up and withdraw from the storage groove, and the pressure in the rodless cavity of the control telescopic rod is reduced. Due to the presence of the first overflow valve and the second overflow valve, the medium in the rodless cavity of the lifting telescopic rod will first enter the rodless cavity of the control telescopic rod through the one-way valve to cause the lifting telescopic rod to contract, and the end of the load-bearing plate falls away from the unloading door. Then the medium in the rod cavity of the articulated telescopic rod enters the rodless cavity of the control telescopic rod through the first overflow valve, driving the articulated telescopic rod to extend, and the movable end of the articulated telescopic rod is embedded in the articulated hole to fix the load-bearing plate, so that the load-bearing plate and the unloading door can be reset without the need for worker operation.

[0014] Optionally, the driving assembly includes a motor, a driving gear and a lifting rack. A clearance cavity is opened in the frame, and the clearance cavity is communicated with the storage slot. The motor is arranged on the frame, and the driving gear is rotatably connected in the clearance cavity and fixedly connected to the output shaft of the motor. The lifting rack is fixedly connected to the bottom of the unloading door and meshingly connected with the driving gear.

[0015] By adopting the above technical solution, when unloading, the motor is started, and the output shaft of the motor drives the driving gear to rotate, driving the lifting rack to drive the unloading door to move downward, so that the unloading door is stored in the storage groove; after unloading is completed, the motor is started again, and the output shaft of the motor drives the driving gear to rotate in the opposite direction, driving the lifting rack to drive the unloading door to move upward, so that the unloading door is moved out of the storage groove, and the material transport bin is closed.

[0016] Optionally, two unloading doors are provided, and two unloading assemblies are also provided, and the unloading doors correspond to the unloading assemblies one by one.

[0017] By adopting the above technical solution, the lane is too narrow and it is difficult for the rubber-wheeled transport vehicle to turn around. The unloading doors are set on opposite sides along the driving direction of the vehicle body, so that the goods in the transport bin can be unloaded on either side of the vehicle body, further improving the applicability of the rubber-wheeled transport vehicle.

[0018] Optionally, two cabs are provided, and the two cabs are respectively arranged at opposite ends of the frame.

[0019] By adopting the above technical solution, the driver can control the driving direction of the rubber-tyred transport vehicle in the corresponding cab instead of controlling the rubber-tyred transport vehicle by moving forward or backward, thereby enhancing driving safety.

[0020] Optionally, infrared sensors are respectively provided on the opposite side walls of the frame for detecting the distance between the vehicle body and the inner wall of the lane, and the infrared sensors are electrically connected to the control platform of the cab.

[0021] By adopting the above technical solution, the infrared sensor can detect the distance between the vehicle body and the inner wall of the tunnel, which is convenient for the driver to judge which side of the vehicle body is more appropriate to unload the materials, thereby controlling the movement of the unloading door on the corresponding side.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. During transportation, the movable end of the articulated telescopic rod is embedded in the hinge hole, and the load-bearing plate is stably fixed at the bottom of the transport bin to ensure the stability of transportation; during unloading, the driving component drives the unloading door to move into the storage slot, squeezes and controls the telescopic rod to shrink it, and controls the medium in the rodless cavity of the telescopic rod to enter the rod cavity of the articulated telescopic rod, driving the articulated telescopic rod to shrink, and the movable end of the articulated telescopic rod withdraws from the hinge hole. At this time, lift the end of the load-bearing plate away from the unloading door, and the goods can slide along the load-bearing plate. By controlling the opening and closing state of the unloading door, the load-bearing plate can be automatically fixed or unlocked, making unloading more automated, saving time and effort; 2. After unloading is completed, the driving assembly drives the unloading door to move up and withdraw from the storage slot. Due to the reduction of the pressure in the rodless cavity of the control telescopic rod and the presence of the first relief valve and the second relief valve, the medium in the rodless cavity of the lifting telescopic rod will first enter the rodless cavity of the control telescopic rod through the one-way valve to cause the lifting telescopic rod to shrink, and the end of the load-bearing plate away from the unloading door falls down. Then, the medium in the rod cavity of the articulated telescopic rod enters the rodless cavity of the control telescopic rod through the first relief valve, driving the articulated telescopic rod to extend, and the movable end of the articulated telescopic rod is embedded in the articulated hole to fix the load-bearing plate. The load-bearing plate and the unloading door can be reset without the need for worker operation. 3. The lane is too narrow, and it is difficult for the rubber-wheeled transport vehicle to turn around. The unloading doors are set on opposite sides along the direction of travel of the vehicle body, so that the goods in the transport bin can be unloaded on either side of the vehicle body, further improving the applicability of the rubber-wheeled transport vehicle.

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The embodiment of the present application discloses a side-unloading mining double-head rubber-wheeled transport vehicle, which includes a vehicle body 1, a driving assembly 2 and a unloading assembly 3. The vehicle body 1 includes two cabs 11, a vehicle frame 12 and a material transport bin 13. The two cabs 11 are respectively fixedly connected to opposite ends of the vehicle frame 12. The material transport bin 13 is fixedly mounted on the top of the vehicle frame 12 and is located between the two cabs 11. The length direction of the material transport bin 13 is the same as the travel direction of the vehicle body 1. The driving assembly 2 and the unloading assembly 3 are both arranged on the vehicle frame 12.

[0027] The material transport bin 13 is a hollow square body with an opening at the top. A discharge door 131 is provided on one side of the material transport bin 13 along its own length direction. A bearing plate 132 is provided on the top of the inner bottom wall of the material transport bin 13. The bottom of the bearing plate 132 abuts against the inner bottom wall of the material transport bin 13. A storage slot 121 for accommodating the discharge door 131 is provided on the top of the vehicle frame 12.

[0028] Reference Figure 2 and Figure 3 The driving assembly 2 includes a motor 21, a driving gear 22 and a lifting rack 23. The motor 21 is fixedly mounted on the frame 12. The output shaft of the motor 21 is fixedly connected to the driving gear 22. A clearance cavity 122 is provided inside the frame 12. The clearance cavity 122 is connected to the storage slot 121. The driving gear 22 is rotatably connected in the clearance cavity 122. The lifting rack 23 is fixedly mounted at the bottom of the discharge door 131. In this embodiment, the driving gear 22 is an incomplete gear. When the discharge door 131 moves, the driving gear 22 is meshed and connected with the lifting rack 23.

[0029] When unloading is required, the motor 21 is started, and the output shaft of the motor 21 drives the driving gear 22 to rotate, driving the lifting rack 23 to drive the unloading door 131 to move downward, so that the unloading door 131 is stored in the storage groove 121; after unloading is completed, the motor 21 is started again, and the output shaft of the motor 21 drives the driving gear 22 to rotate in the opposite direction, driving the lifting rack 23 to drive the unloading door 131 to move upward, so that the unloading door 131 is exposed from the storage groove 121, and the material transport bin 13 is closed.

[0030] Reference Figure 3 and Figure 4 The unloading assembly 3 includes a control telescopic rod 31, two hinged telescopic rods 32 and a lifting telescopic rod 33. The control telescopic rod 31 is fixedly installed in the storage groove 121. The fixed end of the control telescopic rod 31 is fixedly connected to the inner bottom wall of the storage groove 121, and the movable end of the control telescopic rod 31 is fixedly connected to the bottom of the unloading door 131. The fixed ends of the two hinged telescopic rods 32 are respectively fixedly installed on the opposite side walls of the material transport bin 13. The opposite side walls of the bearing plate 132 are provided with hinge holes 1321 for accommodating the movable ends of the hinged telescopic rods 32 to be embedded. When the hinged telescopic rods 32 are retracted, the bearing plate 132 can be rotatably connected to the material transport bin 13. The lifting telescopic rod 33 is fixedly installed on the frame 12 in the vertical direction. The movable end of the lifting telescopic rod 33 is hinged with a connecting block 4, and the connecting block 4 is slidably connected to the bottom of the bearing plate 132.

[0031] It should be noted that the rodless chamber of the control telescopic rod 31 is connected with the rod chamber of the articulated telescopic rod 32, and a first overflow valve 5 is installed between the two; the rod chamber of the articulated telescopic rod 32 is connected with the rodless chamber of the lifting telescopic rod 33, and a second overflow valve 6 is installed between the two, and the starting pressure of the second overflow valve 6 is greater than the starting pressure of the first overflow valve 5; the rodless chamber of the lifting telescopic rod 33 is connected with the rodless chamber of the control telescopic rod 31, and a one-way valve 7 is installed between the two.

[0032] Reference Figure 2 , Figure 3 and Figure 4 During unloading, the output shaft of the motor 21 drives the driving gear 22 to rotate, driving the lifting rack 23 to drive the unloading door 131 to move downward, and the unloading door 131 is stored in the storage groove 121, and the medium in the rodless cavity of the control telescopic rod 31 is pressed into the rod cavity of the hinged telescopic rod 32 through the first overflow valve 5, driving the hinged telescopic rod 32 to contract, and the movable end of the hinged telescopic rod 32 withdraws from the hinge hole 1321, and then the unloading door 131 continues to move downward, and the medium in the rodless cavity of the control telescopic rod 31 enters the rodless cavity of the lifting telescopic rod 33 through the rod cavity of the hinged telescopic rod 32, driving the lifting telescopic rod 33 to extend, and lift the end of the carrying plate 132 away from the unloading door 131, so that the carrying plate 132 is tilted to a certain angle, and the material slides along the carrying plate 132 to complete the unloading.

[0033] After the unloading is completed, the motor 21 is started again, and the output shaft of the motor 21 drives the driving gear 22 to rotate in the opposite direction, driving the lifting rack 23 to drive the unloading door 131 to move upward. At this time, the pressure in the rodless cavity of the control telescopic rod 31 is reduced. Due to the presence of the first relief valve 5 and the second relief valve 6, the medium in the rodless cavity of the lifting telescopic rod 33 will first enter the rodless cavity of the control telescopic rod 31 through the one-way valve 7, causing the lifting telescopic rod 33 to shrink, and the end of the bearing plate 132 away from the unloading door 131 falls. Since the starting pressure of the second relief valve 6 is greater than the starting pressure of the first relief valve 5, the medium in the rod cavity of the articulated telescopic rod 32 will then enter the rodless cavity of the control telescopic rod 31 through the first relief valve 5, driving the articulated telescopic rod 32 to extend, and the movable end of the articulated telescopic rod 32 is embedded in the hinge hole 1321 to fix the bearing plate 132.

[0034] In order to further improve the applicability of the rubber-wheeled transport vehicle, in this embodiment, two discharge doors 131 and two discharge assemblies 3 are provided, and the two correspond to each other. An infrared sensor 8 is installed on the side walls of the frame 12 on both sides (refer to Figure 1 ), which can detect the distance between the vehicle body 1 and the inner wall of the tunnel. The two infrared sensors 8 are electrically connected to the control platform of the cab 11. The driver can choose to unload the materials on any side of the vehicle body 1 according to the specific situation in the tunnel, avoiding the situation where the materials cannot be unloaded due to the narrowness of one side of the tunnel.

[0035] The implementation principle of a side-unloading double-headed rubber-wheeled transport vehicle for mining in the embodiment of the present application is as follows: the driver drives the rubber-wheeled transport vehicle to a designated location, and determines to unload the materials on one side of the vehicle body 1 according to the distance between the vehicle body 1 and the two sides of the tunnel. The motor 21 is started, and the output shaft of the motor 21 drives the driving gear 22 to rotate, driving the corresponding lifting rack 23 to drive the unloading door 131 to move downward, and the unloading door 131 is stored in the storage groove 121, and the medium in the rodless cavity of the control telescopic rod 31 is pressed into the rod cavity of the articulated telescopic rod 32 through the first overflow valve 5, driving the articulated telescopic rod 32 to contract, and the movable end of the articulated telescopic rod 32 withdraws from the articulated hole 1321, while the articulated telescopic rod 32 in the other unloading assembly 3 is still in an extended state, and can serve as the rotation axis of the bearing plate 132. Then the unloading door 131 continues to move downward, controlling the medium in the rodless cavity of the telescopic rod 31 to enter the rodless cavity of the lifting telescopic rod 33 through the rod cavity of the hinged telescopic rod 32, driving the lifting telescopic rod 33 to extend, lifting the end of the carrying plate 132 away from the unloading door 131, and tilting the carrying plate 132 to a certain angle, so that the material slides along the carrying plate 132 to complete the unloading.

[0036] After the unloading is completed, the motor 21 is started again, and the output shaft of the motor 21 drives the driving gear 22 to rotate in the opposite direction, driving the lifting rack 23 to drive the unloading door 131 to move upward. At this time, the pressure in the rodless cavity of the control telescopic rod 31 is reduced. Due to the presence of the first relief valve 5 and the second relief valve 6, the medium in the rodless cavity of the lifting telescopic rod 33 will first enter the rodless cavity of the control telescopic rod 31 through the one-way valve 7, causing the lifting telescopic rod 33 to shrink, and the end of the bearing plate 132 away from the unloading door 131 falls. Since the starting pressure of the second relief valve 6 is greater than the starting pressure of the first relief valve 5, the medium in the rod cavity of the articulated telescopic rod 32 will then enter the rodless cavity of the control telescopic rod 31 through the first relief valve 5, driving the articulated telescopic rod 32 to extend, and the movable end of the articulated telescopic rod 32 is embedded in the hinge hole 1321, fixing the bearing plate 132, and resetting the material transport bin 13. There is no need for workers to unload the materials during the whole process, and the unloading location can be selected. Lifting the carrying plate 132 to a lower height can also allow the materials to slide down, which greatly enhances the applicability of the rubber-wheeled transport vehicle.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
