Description

Technical Field

[0001] This utility model relates to the technical field of emergency rescue equipment in mines, and in particular to a mine drainage vehicle. Background Technology

[0002] A mine shaft is a general term for the shafts, tunnels, equipment, surface buildings and structures that form an underground coal mine production system. Inclined shafts, vertical shafts, and adits in underground mine development are also called mine shafts.

[0003] When a flood occurs in a mine, the existing mine drainage equipment is too bulky. Due to the relatively narrow terrain inside the mine, large mine drainage equipment cannot enter the mine to drain water. It is necessary to connect drainage pipelines to the mine to drain water, which is time-consuming, labor-intensive, inefficient in rescue, and poses safety hazards.

[0004] Existing mine drainage systems use submersible pumps for drainage. Submersible pumps are prone to leakage, posing safety issues. When there is a large drop between the water accumulation point and the ground, the mine drainage system cannot directly reach the water accumulation point for drainage. Furthermore, the drainage pressure of current mine drainage systems is low and cannot meet the requirements for high-lift operations. Summary of the Invention

[0005] Therefore, a mine drainage vehicle is needed to address the technical problems of existing mine drainage devices that use submersible electric pumps for drainage, which are prone to leakage and pose safety issues; when the difference in elevation between the water accumulation point and the ground is large, the mine drainage device cannot directly reach the water accumulation point for drainage; and the current mine drainage device has low drainage pressure, which cannot meet the technical requirements of high-lift operations.

[0006] To achieve the above objectives, the inventor provides a mine drainage vehicle, comprising:

[0007] A mobile chassis, used to drive the drainage vehicle to move;

[0008] A support platform, which is mounted on the mobile chassis;

[0009] A hydraulic system is mounted on the support platform;

[0010] A first hydraulic water pump is located below the support platform, and the hydraulic system is used to provide hydraulic power to the first hydraulic water pump.

[0011] A second hydraulic water pump is placed on the support platform. The hydraulic system is also used to provide hydraulic power to the second hydraulic water pump. The second hydraulic water pump is used to perform drainage operations. The second hydraulic water pump is connected to the first hydraulic water pump through a water supply pipe. The first hydraulic water pump is used to pressurize the water flow to increase the drainage head.

[0012] As a preferred structure of this utility model, the first hydraulic water pump is fixedly installed below the front end of the bearing platform in the forward direction of the drainage vehicle.

[0013] As a preferred structure of this utility model, the inlet and outlet of the first hydraulic water pump are arranged opposite each other along the length of the drainage vehicle.

[0014] As a preferred structure of this utility model, the inlet of the first hydraulic water pump faces the front end of the drainage vehicle along its length, and the outlet of the first hydraulic water pump faces the rear end of the drainage vehicle along its length.

[0015] As a preferred structure of this utility model, the mining drainage vehicle further includes a first pipeline winch and a second pipeline winch, which are respectively disposed on the bearing platform. Both the first pipeline winch and the second pipeline winch are used for retrieving and releasing pipelines.

[0016] As a preferred structure of this utility model, the mining drainage car also includes a drive motor and a bell jar, and the hydraulic system includes a hydraulic pump;

[0017] The drive motor is mounted on the support platform, and the bell is installed at the output end of the drive motor;

[0018] The hydraulic pump is mounted on the bell housing, and the output end of the drive motor is connected to the input end of the hydraulic pump via a coupling.

[0019] As a preferred structure of this utility model, the hydraulic system includes a hydraulic oil tank, a hydraulic pump, and a hydraulic control valve group, and the hydraulic oil tank, the hydraulic pump, and the hydraulic control valve group are connected by pipelines to form a circuit.

[0020] As a preferred embodiment of this invention, the hydraulic system further includes a hydraulic oil cooler, which is disposed on the support platform and is used to dissipate heat from the hydraulic oil in the hydraulic system.

[0021] As a preferred structure of this utility model, the mining drainage vehicle also includes a plurality of lighting lamps, which are respectively arranged around the drainage vehicle.

[0022] As a preferred structure of this utility model, the mining drainage vehicle further includes a detection mechanism and a control system. The control system is set on the bearing platform, the detection mechanism is fixedly set, and the detection mechanism is electrically connected to the control system. The detection mechanism is used to detect obstacles in the environment around the mining drainage vehicle and feed back the detection signal to the control system so that the detection result is displayed on the display screen of the control system.

[0023] Unlike existing technologies, the beneficial effects of the above technical solution are as follows: During drainage operations, the mine drainage vehicle of this utility model only requires drainage via a second hydraulic water pump within a certain range. This second hydraulic water pump is placed at the drainage point. Due to its small size and light weight, the second hydraulic water pump can enter areas with significant drops and confined spaces for drainage. When the drainage head is insufficient and the head of the second hydraulic water pump cannot meet the operational requirements, the second hydraulic water pump is connected to the first hydraulic water pump via a water supply pipe. Specifically, the outlet of the second hydraulic water pump is connected to the inlet of the first hydraulic water pump. The first hydraulic water pump pressurizes the water flow to meet the requirements of high-head operations, adapting to complex emergency rescue environments.

[0059] Please see Figures 1 to 5 This embodiment relates to a mine drainage vehicle, comprising:

[0060] A mobile chassis 1 is used to drive the drainage vehicle. The mobile chassis 1 allows the mine drainage vehicle to move independently, providing flexibility and enabling mobile drainage operations. In this embodiment, a tracked mobile chassis 1 is used. The use of a tracked mobile chassis 1 facilitates traversing muddy and rugged terrain, allowing for self-propelled movement and drainage operations within the mine, thus reducing labor intensity. In other embodiments, a wheeled mobile chassis 1 may be used.

[0061] The support platform 2 is mounted on the mobile chassis 1. The support platform 2 serves as the frame structure of the vehicle and is the base of the vehicle. It supports and connects the various assemblies of the vehicle, keeps the assemblies in a relatively correct position, and bears various loads inside and outside the drainage vehicle.

[0062] A hydraulic system is mounted on the support platform 2;

[0063] The first hydraulic water pump 12 is positioned below the support platform 2, thereby reducing the space occupied on the support platform 2, making efficient use of space, and resulting in a compact structure. The hydraulic system provides hydraulic power to the first hydraulic water pump 12 to drive it to start. The oil pipes of the hydraulic system are connected to the hydraulic motor of the first hydraulic water pump 12. The first hydraulic water pump 12 is a hydraulic water pump, which is small in size and lightweight, facilitating drainage operations.

[0064] A second hydraulic water pump 14 is placed on the support platform 2. The hydraulic system also provides hydraulic power to the second hydraulic water pump 14 to drive it to start. The oil pipes of the hydraulic system are connected to the hydraulic motor of the second hydraulic water pump 14. The second hydraulic water pump 14 is used to perform drainage operations. It is small in size and lightweight, allowing it to enter areas with significant drops and confined spaces for drainage. The second hydraulic water pump 14 is connected to the first hydraulic water pump 12 via a water supply pipe 13. The first hydraulic water pump 12 is used to pressurize the water flow to increase the drainage head. Since both the first hydraulic water pump 12 and the second hydraulic water pump 14 are hydraulic water pumps, and are small in size and lightweight, they can be used in series. The system uses a first hydraulic water pump 12 and a second hydraulic water pump 14. The second hydraulic water pump 14 is responsible for drawing water, while the first hydraulic water pump 12 is responsible for pressurizing. The hydraulic water pumps are lightweight and compact. Depending on the working conditions, the second hydraulic water pump 14 can be used alone, or the first hydraulic water pump 12 and the second hydraulic water pump 14 can be used in series.

[0065] Specifically, in this embodiment, the mine drainage vehicle only needs to use the second hydraulic water pump 14 for drainage within a certain range during the drainage process. The second hydraulic water pump 14 is placed at the drainage point. Due to its small size and light weight, the second hydraulic water pump 14 can enter areas with significant drops and confined spaces for pumping and drainage. When the drainage head is insufficient and the head of the second hydraulic water pump 14 cannot meet the operational requirements, the second hydraulic water pump 14 is connected to the first hydraulic water pump 12 via a water pipe 13. This means the outlet of the second hydraulic water pump 14 is connected to the inlet of the first hydraulic water pump 12. The first hydraulic water pump 12 pressurizes the water flow to meet the high-head operational requirements and adapt to complex emergency rescue environments.

[0066] Optionally, in some embodiments, such as Figures 1 to 5As shown, the first hydraulic water pump 12 is fixedly installed below the front end of the bearing platform 2 in the forward direction of the drainage vehicle, which reduces the space occupied on the bearing platform 2, makes reasonable use of space, has a compact structure, and is convenient to connect with the second hydraulic water pump 14.

[0067] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the inlet and outlet of the first hydraulic water pump 12 are arranged opposite each other along the length of the drainage vehicle, which facilitates the use of the second hydraulic water pump 14 in series with the first hydraulic water pump 12.

[0068] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the inlet of the first hydraulic water pump 12 faces the front end of the drainage vehicle along its length, and the outlet of the first hydraulic water pump 12 faces the rear end of the drainage vehicle along its length. A water delivery pipe 13 is installed at the outlet of the first hydraulic water pump 12, allowing water to enter from the front of the vehicle and exit from the rear.

[0069] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the mining drainage vehicle also includes a first pipeline winch 10 and a second pipeline winch 11. The first pipeline winch 10 and the second pipeline winch 11 are respectively installed on the bearing platform 2. The first pipeline winch 10 and the second pipeline winch 11 are used to retract and extend the oil pipes. The hydraulic oil pipes supplied by the second hydraulic water pump 14 can be retracted and extended through the first pipeline winch 10 and the second pipeline winch 11. The operation is simple, quick, time-saving, labor-saving, and improves work efficiency.

[0070] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the mining drainage vehicle also includes a drive motor 3 and a bell jar 4, and the hydraulic system includes a hydraulic pump 5; the drive motor 3 is mounted on the bearing platform 2, and the bell jar 4 is mounted on the output end of the drive motor 3; the hydraulic pump 5 is mounted on the bell jar 4, and the output end of the drive motor 3 and the input end of the hydraulic pump 5 are connected by a coupling 6, so that the drive motor 3 converts electrical energy into hydraulic energy.

[0071] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the hydraulic system includes a hydraulic oil tank 8, a hydraulic pump 5, and a hydraulic control valve group 9. The hydraulic oil tank 8, the hydraulic pump 5, and the hydraulic control valve group 9 are connected by pipelines to form a circuit.

[0072] Optionally, in some embodiments, such as Figures 1 to 5As shown, the hydraulic system also includes a hydraulic oil cooler 7, which is mounted on the support platform 2. The hydraulic oil cooler 7 is used to dissipate heat from the hydraulic oil in the hydraulic system to reduce the temperature of the hydraulic oil and ensure the normal operation of the hydraulic system.

[0073] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the mining drainage vehicle also includes a plurality of lighting lamps 16, which are respectively arranged around the drainage vehicle to provide illumination when the vehicle is in motion.

[0074] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the mine drainage vehicle also includes a detection mechanism 17 and a control system 15. The control system 15 is mounted on the support platform 2, and the detection mechanism 17 is fixedly mounted around the support platform 2. The detection mechanism 17 is electrically connected to the control system 15. The detection mechanism 17 is used to detect obstacles in the environment surrounding the mine drainage vehicle and feeds back the detection signal to the control system 15 so that the detection result is displayed on the display screen of the control system 15. By providing the detection mechanism 17, during the movement of the mine drainage vehicle, the detection mechanism 17 detects obstacles in the environment surrounding the mine drainage vehicle and feeds back the detection signal to the control system 15 so that the detection result is displayed on the display screen of the control system 15. This reminds the operator to avoid obstacles when operating the mine drainage vehicle, facilitating the movement of the mine drainage vehicle and improving rescue efficiency. Preferably, in this embodiment, as... Figures 1 to 5 As shown, the detection mechanism 17 is an infrared obstacle avoidance sensor. There are two or more infrared obstacle avoidance sensors, which are fixedly installed around the carrying platform 2 of the mine drainage truck. It should be noted that in this embodiment, the number of infrared obstacle avoidance sensors is not limited. Preferably, in this embodiment, there are eight infrared obstacle avoidance sensors, that is, two infrared obstacle avoidance sensors are provided on each side. Infrared obstacle avoidance sensors are chosen because they have good environmental adaptability, can work at night and in adverse weather conditions; have good concealment, are not easily interfered with; and are small in size, light in weight, and have low power consumption.

[0075] Specifically, in this embodiment, the mine drainage vehicle, during drainage operations, only requires drainage via the second hydraulic water pump 14 within a certain range. The second hydraulic water pump 14 is placed at the drainage point, and then the hydraulic system's oil pipes are connected to the second hydraulic water pump via the first and second pipe winches 10 and 11. Finally, the water supply pipe 13 is connected to the outlet of the second hydraulic water pump 14 to perform the drainage operation. Because the second hydraulic water pump 14 is small and lightweight, it can enter areas with significant drops and confined spaces for drainage. When the drainage head is insufficient and the head of the second hydraulic water pump 14 cannot meet the operational requirements, the second hydraulic water pump 14 is connected to the first hydraulic water pump 12 via the water supply pipe 13. This means the outlet of the second hydraulic water pump 14 is connected to the inlet of the first hydraulic water pump 12, where the first hydraulic water pump 12 pressurizes the water flow to meet the high-head operational requirements and adapt to complex emergency rescue environments.

[0076] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
