[0022] Example See also Figure 1-9The present invention provides a crawler-type amphibious drainage vehicle for mining, including a drainage vehicle body 1, buoyancy boxes 2 are arranged on both sides of the drainage vehicle body 1, a crawler drive module 3 is arranged at the lower part of the drainage vehicle body 1, a propeller propulsion module 4 and a quick-connection joint module 7 are arranged at the rear end of the drainage vehicle body 1, and a power supply and control module 5 and a drainage module 6 are arranged inside the drainage vehicle body 1, and the drainage module 6 passes through the drainage vehicle body 1 and is connected to the quick-connection joint module 7. When the drainage vehicle body 1 is traveling in a waterless or shallow water area, the crawler drive module 3 provides power for the drainage vehicle; when the drainage vehicle is traveling in a deep water area, buoyancy boxes 2 are installed on both sides of the vehicle body to ensure that the drainage vehicle floats on the water surface, and the propeller propulsion module 4 provides power for the drainage vehicle.

[0023] The track drive module 3 includes a driving wheel 32 and a guide wheel 33 symmetrically arranged on both sides of the bottom of the drainage vehicle body 1. The guide wheel 33 and the driving wheel 32 are covered with a track 31 on the outside. The track 31 is made of a light-weight, low-vibration, corrosion-resistant rubber material with a low grounding pressure, which helps to reduce damage to the tunnel surface.

[0024] The driving wheel 32 is driven by a first driving motor 36, which is arranged inside the drainage vehicle body 1. The driving wheel 32 is arranged in a rear-end manner to reduce the length of the tensioning section of the track 31 and increase the service life of the track 31. Two supporting rollers 34 are arranged between the driving wheel 32 and the guide wheel 33, and the two supporting rollers 34 are connected to the bottom frame of the drainage vehicle body 1. The guide wheel 33 is connected to one end of the tensioning assembly 35, and the other end of the tensioning assembly 35 is connected to the bottom frame.

[0025] The tensioning assembly 35 includes a tensioning spindle 351, one end of which is connected to a tensioning support 352 through a bearing, and the other end of the tensioning spindle 351 is fixedly connected to a hexagonal bolt 358 through welding, and the hexagonal bolt 358 is connected to a hexagonal nut 357, and the hexagonal nut 357 is fixed to the bottom frame. A tensioning spring 353 is sleeved on the tensioning spindle 351, and the two ends of the tensioning spring 353 are respectively connected to a first spring support 355 and a second spring support 356. A connecting piece 354 is provided at the connection between the tensioning support 352 and the guide wheel support 350, and the guide wheel support 350 is connected to the guide wheel 33.

[0026] Fix the hexagonal nut 357 and rotate the hexagonal bolt 358 to make the tensioning main shaft 351 realize spiral movement. Since the tensioning main shaft 351 and the tensioning support 352 can rotate relatively, the tensioning support 352 only moves in the axial direction, that is, the guide wheel 33 moves in the axial direction, thereby achieving the tensioning effect on the crawler 31. The position of the guide wheel 33 is controlled by the tensioning assembly 35, and the tensioning force of the crawler 31 is adjusted to prevent the crawler 31 from slipping during operation and reduce vibration, thereby ensuring the stable movement of the amphibious drainage vehicle in the tunnel.

[0027] The propeller propulsion module 4 includes a propeller 41 and a second drive motor 42. The second drive motor 42 is arranged inside the drainage vehicle body 1 and drives the propeller 41 to rotate. The propeller 41 is arranged below the rear end of the drainage vehicle body 1.

[0028] The power supply and control module 5 includes a lithium battery pack 51 disposed inside the drainage vehicle body 1, a BMS 52 is disposed on one side of the lithium battery pack 51, and a control box 53 is disposed on the upper part of the lithium battery pack 51. The BMS 52 is a battery management system that detects, evaluates and manages the lithium battery pack 51 to ensure that the lithium battery pack 51 works safely, reliably and efficiently, and the control box 53 can realize remote control of the drainage vehicle body 1.

[0029] The drainage module 6 includes a first mixed flow pump group 68 and a second mixed flow pump group 69. The second mixed flow pump group 69 and the first mixed flow pump group 68 each include two mixed flow pumps. The mixed flow pumps each include a mixed flow pump head 61 and a mixed flow pump motor 62, which are fixed inside the drainage vehicle body 1 by fixing bolts.

[0030] The water inlet end of the mixed flow pump is connected to a bottom valve 64 through a first pipe 63, and the bottom valve 64 is arranged at the bottom of the drainage vehicle body 1, and the distance from the end of the bottom valve 64 to the bottom of the drainage vehicle body 1 is 6 cm. The water outlet end of the mixed flow pump is connected to a fourth pipe 67 through a second pipe 65 and a third pipe 66, and the fourth pipe 67 is arranged above the rear end of the drainage vehicle body 1.

[0031] The first pipe 63, the second pipe 65, the third pipe 66, the fourth pipe 67 and the bottom valve 64 are all fixedly connected to the drainage vehicle body 1 through flanges, and the drainage vehicle body 1 is provided with through holes and threaded holes at corresponding connection positions. Figure 4 As shown, the bottom valve 64 and the first pipe 63 are fixed to the drainage vehicle body 1 through a flange, and the sealing surface of the flange connection is a tongue-and-groove surface. The tongue-and-groove surface is selected to form an embedded structure between the two connected parts to achieve accurate positioning of the parts. The tongue-and-groove surface is provided with a first sealing gasket 81 and a rubber O-ring 82 for sealing. The first sealing gasket 81 is an asbestos rubber sheet gasket. Through a three-layer sealing method, the sealing performance of the entire system is improved. The second pipe 65, the third pipe 66 and the fourth pipe 67 are also fixed to the drainage vehicle body 1 in this way. The sealing method is the same, so it is not repeated here.

[0032] The quick-connect joint module 7 includes a first quick-connect joint group 71 and a second quick-connect joint group 72. Both the second quick-connect joint group 72 and the first quick-connect joint group 71 include a groove quick-connect joint 74 and a tenon quick-connect joint 73. The tenon quick-connect joint 73 is connected to the fourth pipe 67. One end of the groove quick-connect joint 74 is connected to the tenon quick-connect joint 73, and the other end is connected to a flexible pipe. The flexible pipe is connected to the vertical shaft to feed water to the large submersible pump.

[0033] Buckles 75 are provided at both ends of the tenon quick connector 73, and buckle grooves are provided on the inner side of the buckle 75. Slots 76 are provided at both ends of the slot quick connector 74, and quick connector connecting pieces 77 are provided on the outer side of the slots 76. The quick connector connecting pieces 77 are clamped in the buckle grooves, and the buckles 75 are clamped in the slots 76. A second sealing gasket 78 is provided on the connecting surface of the slot quick connector 74 and the tenon quick connector 73. The second sealing gasket 78 is a polytetrafluoroethylene sealing gasket, which has the advantages of corrosion resistance, smooth contact surface, and low friction coefficient. It can ensure the sealing performance while taking into account the smoothness of rotation during quick connection. Figure 5 As shown, the connection method of the groove type quick connector 74 and the tenon type quick connector 73 is to press the buckle 75 into the groove 76, press it tightly and flatten it, and rotate the buckle 75 clockwise to make the buckle 75 completely contact with the quick connector connecting piece 77. At this time, the tenon type quick connector 73 squeezes the polytetrafluoroethylene sealing gasket installed in the groove type quick connector 74 to cause it to deform and achieve a sealing effect.

[0034] like Figure 3 As shown, when the drainage vehicle body 1 is performing drainage work, the water rushing in the tunnel is filtered through the bottom valve 64, enters the mixed flow pump through the first pipe 63, reaches the tail of the drainage vehicle body 1 through the second pipe 65, passes through the fourth pipe 67, and is connected to the flexible pipe through the quick-connect joint module 7 to discharge the water rushing into the vertical shaft to feed water for the large submersible pump.

[0035] The flexible pipe quick connection method of the above crawler-type mining amphibious drainage vehicle comprises the following steps: Step 1: When the amphibious drainage vehicle needs to change the drainage area, the first mixed flow pump group 68 continues to perform the drainage operation, and the second mixed flow pump group 69 stops working; Step 2: Disconnect the grooved quick-connect joint 74 and the tenon quick-connect joint 73 of the second quick-connect joint group 72, disconnect the second mixed-flow pump group 69 from the connected soft pipe, connect the two ends of a water hose to the end of the amphibious drainage vehicle and the flexible pipe of the second mixed-flow pump group 69 through the grooved quick-connect joint 74 and the tenon quick-connect joint 73, and lay the water hose deep into the tunnel; Step 3: The first mixed flow pump set 68 stops working, the groove type quick-connect joint 74 and the tenon type quick-connect joint 73 of the first quick-connect joint set 71 are disconnected, the first mixed flow pump set 68 is disconnected from the connected flexible pipe, and the amphibious drainage vehicle is moved until the water hose is fully spread out; Step 4: The amphibious drainage vehicle brakes, and the second mixed flow pump group 69 immediately starts drainage operation, connecting the two ends of a water hose to the flexible pipes of the end of the amphibious drainage vehicle and the first mixed flow pump group 68 through the groove type quick-connect joint 74 and the tenon type quick-connect joint 73 respectively; Step 5: Determine whether the amphibious drainage vehicle has reached the designated location: If yes, start the first mixed flow pump group 68 to perform drainage operations and complete the moving task; If no, return to step 1 and repeat the flexible pipe quick connection steps until the amphibious drainage vehicle reaches the designated drainage location.

[0036] Therefore, the present invention adopts the above-mentioned crawler-type amphibious drainage vehicle for mining and the flexible pipe quick connection method. The amphibious drainage vehicle has a dual drive mode of crawler and propeller, which ensures that the drainage vehicle can reach the designated area at the first time under different environments; the amphibious drainage vehicle is used as a front pump to feed water for large submersible pumps in the mine, and by using a flexible pipe quick connection method, the amphibious drainage vehicle can be quickly moved to the deep part of the tunnel; the amphibious drainage vehicle has a mixed flow pump group inside. When the drainage vehicle needs to change its working position, the mixed flow pump can be controlled to alternately operate and deploy, ensuring that the amphibious drainage vehicle works uninterruptedly, ensuring the continuous operation of the large submersible pumps in the vertical shaft, and improving drainage efficiency.
