Description

Technical Field

[0001] This invention relates to a quick-change device for connection parts, specifically a compact quick-change mechanism for the power unit of a mining vehicle. Background Technology

[0002] In recent years, my country's coal mining output has been continuously increasing, and the number of newly built mines has gradually grown. New energy mining vehicles are widely used in various mines. Considering the range and charging efficiency of the power unit, a direct power unit replacement solution is often adopted. However, due to the limited space for underground vehicle operation and the restriction on the size of the cage for vertical shaft mining vehicles, a compact vehicle structure is needed to improve convenience. Currently, existing replacement mechanisms are generally externally mounted, requiring significant space for assembly, which affects vehicle operation, and also has a low level of intelligence. This invention fully considers the efficiency and safety of frequent power unit replacements, while also taking into account the large size of current replacement mechanisms, which affects the mining vehicle's ability to enter the cage. Therefore, a compact, fast, and safe replacement mechanism is designed to ensure the efficiency and safety of power unit replacement for new energy mining vehicles. Summary of the Invention

[0003] To address the technical problem of rapid replacement of power units in underground coal mine vehicles, this invention provides a compact and rapid replacement mechanism for power units in mining vehicles.

[0004] The technical solution of the present invention is a compact quick-change mechanism for the power unit of a mining vehicle, comprising a quick-change module 1 connected to the vehicle, a quick-change module 2 connected to the power unit, an electronic control system, and a hydraulic system.

[0005] The quick-change module includes a lifting plate, a sliding plate, and a locking plate. The sliding plate is located between the lifting plate and the locking plate. The lifting plate has two elongated holes, and an upper hook is located on the outer side of the lifting plate. A lifting cylinder is located on the outer side of the lifting plate. A lower lifting hook and a lifting component are located on the outer side of the sliding plate. The lower lifting hook passes through the first elongated hole, and the lifting component passes through the second elongated hole. The lifting cylinder connects to the lifting component, causing the lower lifting hook and the upper hook to close and achieve a fixing function. A slide rail and a locking lug are located on the inner side of the sliding plate. A locking hole is located on the locking plate. A slide groove is located on the inner side of the locking plate. A locking cylinder and a locking ring are located on the outer side of the locking plate. The slide rail corresponds to the slide groove, the locking lug passes through the locking hole, and the locking cylinder corresponds to the locking ring.

[0006] The quick-change module 2 includes a fixed plate with a lifting column on it. The lower lifting hook and the upper hook lock the lifting column in place when they are closed.

[0007] The lifting plate has a wedge-shaped edge, and the fixing plate has a wedge-shaped groove on its inner edge. The wedge-shaped edge and the wedge-shaped groove fit together when they are connected.

[0008] A displacement sensor is installed on the outside of the sliding plate. Once the sliding plate rises to a certain height, the displacement sensor is triggered, which can stop the lifting action.

[0009] The vehicle is equipped with a shape memory alloy switching valve and a battery unloading button, and laser sensors are installed on quick-swap module one and quick-swap module two, respectively.

[0010] The electronic control system includes a control device, which is electrically connected to a battery unloading button, a shape memory alloy control valve, an electro-hydraulic directional valve, and a displacement sensor. The shape memory alloy control valve controls the vehicle's braking circuit, and the battery unloading button is connected to a laser sensor.

[0011] The aforementioned shape memory alloy control valve assembly structure includes a switch housing, a control circuit junction box, a control coil, a push cylinder, a magnetically controlled shape memory alloy, a push rod, a trigger block, a connecting block, and a terminal block. The upper part of the switch housing is provided with a push cylinder, and the lower part is provided with two connecting blocks. The inner side wall of the switch housing is provided with a control coil. The push cylinder is provided with a push rod and a magnetically controlled shape memory alloy. The push rod is engaged with the magnetically controlled shape memory alloy, and the lower end of the push rod is provided with a trigger block.

[0012] The hydraulic system includes a hydraulic pump, an oil filter, and an electrically controlled directional valve connected in sequence; the electrically controlled directional valve is connected to the lifting cylinder and the locking cylinder through a balance valve and a sequence valve, respectively.

[0013] The beneficial effects of this invention are: it enables rapid replacement of the power unit, effectively reduces the length of the vehicle, improves the vehicle's ability to go down into the well and adapt to different cage sizes, avoids the disassembly and reassembly of the vertical shaft transport vehicle and secondary operations, and makes the vehicle more adaptable in its working state.

Detailed Implementation

[0033] like Figure 1 , 2 As shown, a compact quick-change mechanism for the power unit of a mining vehicle includes a quick-change module 2 connected to the vehicle 1, a quick-change module 3 connected to the power unit 4, an electronic control system 5, and a hydraulic system 6.

[0034] like Figure 3 , 4 As shown in figures 5, 6, 7, 8, 9, 10, 11, and 12, the quick-change module 2 includes a lifting plate 2.3, a sliding plate 2.2, and a locking plate 2.1. The sliding plate 2.2 is located between the lifting plate 2.3 and the locking plate 2.1. The lifting plate 2.3 has two elongated holes, a first hole 2.8 and a second hole 2.9. An upper hook 7 is provided on the outer side of the lifting plate 2.3, and a lifting cylinder 6.8 is provided on the outer side of the lifting plate 2.3. A lower lifting hook 8 and a lifting component 9 are provided on the outer side of the sliding plate 2.2. The lower lifting hook 8 passes through the first hole 2.8 and the lifting component 2.8. The lifting cylinder 6.8 passes through the elongated hole 2.9 and connects to the lifting component 2.8, so that the lower lifting hook and the upper hook close to achieve the fixing function. The inner side of the sliding plate 2.2 is provided with a slide rail 2.4 and a locking ear plate 2.5. The locking plate 2.1 is provided with a locking hole 2.6. The inner side of the locking plate 2.1 is provided with a sliding groove 2.7. The outer side of the locking plate 2.1 is provided with a locking cylinder 6.9 and a locking ring 10. The slide rail 2.4 corresponds to the sliding groove 2.7. The locking ear plate 2.5 passes through the locking hole 2.6. The locking cylinder 6.9 corresponds to the locking ring 10.

[0035] like Figure 13As shown, the quick-change module 2 3 includes a fixed plate, on which a lifting column 3.1 is provided. When the lower lifting hook 8 and the upper hook 7 are closed, the lifting column 3.1 is locked in place.

[0036] like Figure 7 The lifting plate 2.3 shown in the diagram has a wedge-shaped edge 11, and the inner edge of the fixing plate has a wedge-shaped groove 3.2. The wedge-shaped edge 11 and the wedge-shaped groove 3.2 fit together after docking. The wedge-shaped connection structure, in conjunction with the laser sensor, enables rapid positioning during the vehicle power unit replacement process, improving transportation efficiency.

[0037] A displacement sensor 5.4 is installed on the outer side of the sliding plate 2.2. When the sliding plate 2.2 rises to a certain height, the displacement sensor 5.4 is triggered, which can stop the lifting action. This allows for the detection of two types of hydraulic cylinder position states, effectively ensuring the safety of quick power unit changes.

[0038] Vehicle 1 is equipped with a shape memory alloy switching valve 5.5 and a battery removal button 5.1. Laser sensors 5.3 are respectively installed on quick-swap module 2 and quick-swap module 3. The interaction between the laser sensors 5.3 can detect the distance between quick-swap module 2 and quick-swap module 3.

[0039] like Figure 17 As shown, the electronic control system 5 includes a control device 5.2, which is electrically connected to a battery unloading button 5.1, a memory alloy control valve 5.5, an electro-hydraulic directional valve 6.5, and a displacement sensor 5.4. The memory alloy control valve 5.5 controls the vehicle braking circuit 5.6, and the battery unloading button 5.1 is connected to a laser sensor 5.3.

[0040] like Figure 14 , 15 As shown, the shape memory alloy control valve assembly 5.5 includes a switch housing 5.5.1, a control circuit junction box 5.5.2, a control coil 5.5.3, a push cylinder 5.5.4, a magnetically controlled shape memory alloy 5.5.5, a push rod 5.5.6, a trigger block 5.5.7, a connecting block 5.5.8, and a terminal block 5.5.9. The upper part of the switch housing 5.5.1 is provided with the push cylinder 5.5.4, and the lower part is provided with two connecting blocks 5.5.8. The inner side wall of the switch housing 5.5.1 is provided with the control coil 5.5.3. The push cylinder 5.5.4 is provided with the push rod 5.5.6 and the magnetically controlled shape memory alloy 5.5.5. The push rod 5.5.6 is engaged with the magnetically controlled shape memory alloy 5.5.5. The lower end of the push rod 5.5.6 is provided with the trigger block 5.5.7.

[0041] The working principle of the memory alloy switching valve 5.5 is as follows: The magnetically controlled memory alloy 5.5.5 is a memory alloy spring with two states, and the spring length is changed through magnetic control. Initially, the magnetically controlled memory alloy 5.5.5 is in its long state. The trigger block 5.5.7 connects the two connecting blocks 5.5.8 to achieve conductivity, the switching valve closes, and the size braking restriction is released. When the control coil 5.5.3 is energized, the magnetically controlled memory alloy 5.5.5 contracts under the action of the magnetic field, pushing the push rod 5.5.6 upward, causing the trigger block 5.5.7 to move upward, the two connecting blocks 5.5.8 to disconnect, the switching valve opens, and it is in the braking restriction state. When the electromagnetic coil is de-energized, the magnetically controlled memory alloy 5.5.5 returns to its initial state.

[0042] like Figure 18 As shown, the hydraulic system includes a hydraulic pump 6.1, an oil filter 6.2, and an electrically controlled directional valve 6.5 connected in sequence. The electrically controlled directional valve 6.5 is connected to a lifting cylinder 6.8 and a locking cylinder 6.9 via a balance valve 6.7 and a sequence valve 6.6, respectively. A relief valve 6.3 is provided between the oil filter 6.2 and the electrically controlled directional valve 6.5.

[0043] The vehicle 1 described in this invention is generally equipped with three power units 4, which can ensure that one power unit 4 is in use, one is on standby, and one is being charged.

[0044] When vehicle 1 needs to replace power unit 4, first drive vehicle 1 to the designated replacement position. At this time, the driver presses the battery removal button 5.1 on the vehicle, activating the control device 5.2 in the electronic control system 5 to operate the memory alloy control valve group 5.5, activating the vehicle braking circuit 5.6, putting vehicle 1 in a braking state. Simultaneously, the electronically controlled directional valve 6.5 activates the hydraulic system, causing the locking cylinder 6.9 to work, releasing the locking lug. After reaching its position, the balance valve 6.7 locks, and simultaneously the lifting cylinder 6.8 actuates, moving the sliding plate 2.2 downwards along the sliding groove. The lower lifting hook on the sliding plate 2.2 also moves downwards, causing the lifting column to move downwards, thus removing power unit 4. Once power unit 4 is unloaded, the balance valve 6.7 corresponding to the lifting cylinder 6.8 locks, simultaneously triggering the electronically controlled position displacement sensor 5.4, which transmits a signal to the control device. Upon receiving the signal from displacement sensor 5.4, the electronic control system manipulates the shape memory alloy control valve assembly 5.5 to release the vehicle's braking circuit, placing the vehicle in a state of unrestricted braking. The vehicle's power supply line is then replaced via cable, switching from the existing power unit to the backup power unit. Loading of the new power unit begins.

[0045] The driver maneuvers vehicle 1 to approach the backup power unit. Laser sensor 5.3 detects the distance and position between vehicle 1 and power unit 4. Based on the wedge-shaped docking connection structure, vehicle 1 and power unit 4 are fully engaged. When vehicle 1 and power unit 4 reach the appropriate position, vehicle 1 is prompted to stop. This allows for rapid positioning during power unit replacement, improving transportation efficiency. At this time, the driver presses the vehicle power unit loading button. The electronic control system operates the shape memory alloy control valve group to control the vehicle braking circuit and restrict the vehicle to a braking state. Simultaneously, by activating the electronically controlled directional valve 6.5, the hydraulic system starts working, the lifting cylinder 6.8 actuates, and the sliding plate 2.2 moves upward along the sliding groove. The lower lifting hook 8 on the sliding plate 2.2 moves upward and pulls the lifting column 3.1, lifting power unit 4. When power unit 4 is lifted into position, the balance valve 6.7 corresponding to the lifting cylinder 6.8 locks, and the lower lifting hook 8 and upper hook 7 close, locking the lifting column 3.1, thus locking the quick-change unit two.

[0046] Simultaneously, displacement sensor 5.4 is triggered, transmitting a signal to the control device. The sequence valve actuates, and locking cylinder 6.9 operates. Upon reaching its position, the balance valve locks, and locking cylinder 6.9 passes through the locking lug, thus doubly locking the quick-change device and improving vehicle safety during operation. Simultaneously, the electronic control system manipulates the shape memory alloy control valve group 5.5 to control the vehicle's braking circuit 5.6, releasing the vehicle from braking restrictions. The vehicle then begins normal operation.
