Description

Technical Field

[0001] This utility model belongs to the technical field of mining vehicles, specifically a universal working jaw for mining clearing vehicles. Background Technology

[0002] With the continuous improvement of the performance and quality of mining vehicles, electric wheeled recovery vehicles are playing an increasingly important role in the breakdown rescue of large dump trucks in mining areas. As a dedicated breakdown towing vehicle for large mining trucks, electric wheeled recovery vehicles not only need to have strong towing capacity, but also need to quickly and efficiently complete the recovery operations of various types of vehicles in complex mining environments. During recovery operations, the working jaws are an important load-bearing device for connecting the recovery vehicle to the disabled vehicle. They are mainly used to fix the towing point, bear the towing force, and achieve safe towing of the vehicle. The working jaws connect to the towing bar or bumper of the disabled vehicle to transfer the traction force of the recovery vehicle to the vehicle being rescued. They are the core component that ensures the stability and safety of recovery operations.

[0003] However, the bumper designs, sizes, and towing point positions of different mining dump trucks vary considerably, which significantly limits the versatility of existing working jaws. Currently, most working jaw designs on the market are only designed for a single vehicle model or a fixed-size towing point, making it difficult to adapt to multiple vehicle models. When a recovery vehicle needs to tow a different model of disabled vehicle, it is often necessary to replace it with a special working jaw that matches the model. In emergency rescue environments in mining areas, this limitation of single-model compatibility affects the operational efficiency and safety of recovery vehicles. Utility Model Content

[0025] Please see Figure 1-4 As shown in the present invention, a universal working jaw for a mine clearing vehicle includes two transition seat assemblies 1. The two transition seat assemblies 1 are detachably connected to the towing bar 100 of the disabled vehicle. A jaw body 2 is detachably connected between the two transition seat assemblies 1. An angle adjustment mechanism 3 is provided on the jaw body 2. The angle adjustment mechanism 3 can adjust the jaw angle by rotating or slightly swinging, so that the jaw and the towing point are in the same direction, effectively preventing the generation of off-center load and torsional torque. In practical use, the operator first selects the transition seat assembly 1 according to the model of the faulty vehicle and connects it to the upper two sides of the towing bar 100 of the faulty vehicle. Then, the jaw body 2 is detachably connected to the transition seat assembly 1. The jaw body 2 is finely adjusted by the angle adjustment mechanism 3 so that the clearing jaw body 2 fits with the towing surface of the towed vehicle. When the clearing vehicle starts towing, the force is transmitted through the jaw body 2 to the towing plate 11 and the vehicle towing bar 100, forming a stable force transmission path. There is no need to change the jaw during clearing operations. It can be matched with various types of dump trucks. There is no need to change the working jaw during clearing operations, which improves clearing efficiency and reduces clearing vehicle operation time.

[0026] In one embodiment, see Figure 1 , Figure 2 and Figure 3As shown, the transition seat assembly 1 includes a traction plate 11, on which L-shaped mounting plates 12 are provided. The two L-shaped mounting plates 12 are detachably connected to the tow bar 100 of the disabled vehicle. A mounting sealing plate 13 is provided on one side of the upper part of the traction plate 11. In actual use, the operator first adjusts the position of the L-shaped mounting plates 12 according to the structure of the towed vehicle's tow bar, ensuring that their threaded holes correspond to the fixing holes on the disabled vehicle's tow bar 100, and then fixes them with bolts. At this time, the traction plate 11 and the mounting sealing plate 13 form a rigid whole, which can evenly distribute the traction load from the jaw body 2, preventing deformation or slippage caused by excessive local force. After the transition seat assembly 1 is installed, it is connected to the jaw body 2 through the mounting assembly 22, forming a complete universal jaw body 2 structure. When the tow truck performs a towing operation, the traction force is transmitted to the traction plate 11 via the jaw body 2, and then to the disabled vehicle's tow bar 100 via the L-shaped mounting plates 12, achieving smooth and safe towing. This structure is easy to assemble and disassemble, and has reliable connections, making it suitable for clearing obstacles for various types of dump trucks in mining areas.

[0027] In one embodiment, see Figure 1 , Figure 2 and Figure 2 As shown, a reinforcing plate 14 is also provided between the L-shaped mounting plate 12 and the mounting sealing plate 13. During assembly, the L-shaped mounting plate 12 is first fixed to the towing plate 11, and its alignment with the threaded hole of the disabled vehicle's towing bar 100 is adjusted. Then, the reinforcing plate 14 is positioned and installed between the L-shaped mounting plate 12 and the mounting sealing plate 13. The reinforcing plate 14 is connected to the L-shaped mounting plate 12 and the mounting sealing plate 13 by full-seam welding or bolt fastening, forming a stable triangular support system. This improves the deformation resistance of the L-shaped mounting plate 12 under tension and shear conditions.

[0028] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the jaw body 2 includes a mounting main board 21, with mounting components 22 on both sides of the mounting main board 21. The two mounting components 22 are detachably connected to the transition seat assembly 1. An angle adjustment mechanism 3 is located in the middle of the mounting main board 21. During operation, the jaw body 2 forms an integral force-bearing structure with the mounting components 22 and the two transition seat assemblies 1. When a tow truck tows the vehicle, the pulling force is transmitted through the jaw body 2 to the mounting main board 21, and then through the mounting components 22 on both sides and the transition seat assembly 1 to the tow bar of the disabled vehicle, achieving stable towing. The angle adjustment mechanism 3 allows the jaw body 2 to be quickly installed and its angle flexibly adjusted to adapt to different bumper or towing point heights and angles during tow operations on different vehicle types.

[0029] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the mounting assembly 22 includes a first upright plate 221, a second upright plate 222, a third upright plate 223, and a fourth upright plate 224. The first upright plate 221, the second upright plate 222, the third upright plate 223, and the fourth upright plate 224 are evenly arranged on the mounting main plate 21 along the length direction. A pin 4 is provided between the first upright plate 221 and the second upright plate 222. A traction plate 11 is detachably connected to the first upright plate 221 and the second upright plate 222 through the pin 4. The traction plate 11 is also provided with a mounting hole 111, and the pin 4 is detachably connected in the mounting hole 111. During assembly, the operator places the traction plate 11 between the first upright plate 221 and the second upright plate 222, aligns its mounting hole 111 with the pin hole on the upright plate, inserts the pin 4, and locks it, thereby forming a reliable hinged connection. This hinged connection allows the traction plate 11 to swing at a small angle in the vertical direction to adapt to the differences in the height or tilt angle of the tow bar of different vehicle models. The third upright plate 223 and the fourth upright plate 224 are located at the other end of the mounting main plate 21. An angle adjustment mechanism 3 is installed between them. A ball joint seat 31 is fixed between the two upright plates and is used to connect the jaw body 2 and ball pin 32 and other components, thereby realizing the fine adjustment function of the jaw body 2 angle. The first upright plate 221 and the second upright plate 222 form an insertion groove for the traction plate 11. The traction plate 11 is positioned and connected by a pin 4. Since the pin 4 adopts a cylindrical insertion fit, it can be inserted only by aligning the hole during assembly. When disassembling, the pin 4 can be pulled out to achieve quick separation. The whole process does not involve complex tools or high-strength threaded connection operations. In addition, the symmetrical distribution of multiple upright plates not only ensures uniform force during use, but also makes the force direction of each connection point singular and avoids jamming during assembly and disassembly, thus avoiding the problem of traditional rigid connections being difficult to disassemble due to deformation under force.

[0030] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, each of the first upright plates 221 is rotatably connected to a tightening screw 5. During installation or adjustment, the operator first connects the traction plate 11 to the two upright plates via the pin 4, so that the traction plate 11 remains rotatable between the first upright plate 221 and the second upright plate 222. The angle adjustment mechanism 3 is adjusted according to the actual towing conditions to align the angle of the jaw body 2 with the vehicle towing direction. After the angle is determined, the tightening screw 5 is rotated so that its end gradually presses against the surface of the traction plate 11. When the pressure is felt to be in place and a pre-tightening force is generated, the locking is completed. At this time, the traction plate 11 is firmly pressed, and the pin 4 and the tightening screw 5 form a double fixation to prevent loosening or displacement during towing. If disassembly or adjustment is required again, simply rotate the tightening screw 5 counterclockwise to remove it from the surface of the traction plate 11 to restore the free swing state. Then, the pin 4 can be pulled out to complete the quick separation.

[0031] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, a pressure plate 6 can also be detachably connected to the first upright plate 221. A pin 4 is abutted against one side of the pressure plate 6. The pressure plate 6 is fixed to the first upright plate 221 by threads and presses or lightly presses the pin 4 on one side to form a mechanical block, so that the pin is constrained in the direction of force. It is used in conjunction with the tightening screw 5 to achieve double locking of the traction plate 11, so that the pin 4 is constrained in the direction of force, preventing it from shifting or falling off during dragging. At the same time, it ensures that the position of the traction plate 11 remains accurate after the angle adjustment is completed, and ensures that the jaw body 2 structure is stable and reliable after the angle adjustment.

[0032] In one specific embodiment, please refer to Figure 1 , Figure 2 and Figure 3 As shown, a support seat 7 is also provided on one side of the upper part of the third upright plate 223. The support seat 7 is located on one side of the upper part of the third upright plate 223 and abuts against the rear end face of the mounting plate 13. Its main function is to provide additional support and positioning constraints for the mounting plate 13, thereby enhancing the overall stability of the transition seat assembly 1.

[0033] In one specific embodiment, please refer to Figure 1 , Figure 2 and Figure 4 As shown, mounting motherboard 21 has mounting holes 211 on both sides of its upper part. These holes are used to mount the chain 8. During use, the operator fixes the jaw body 2 to the transition seat assembly 1 via the mounting component 22, and simultaneously hooks the chain 8 into the mounting holes 211 and secures it to the rear axle housing of the wrecker, creating additional restraint. When the wrecker is towing, the jaw body 2 primarily transmits traction force through the mounting component 22. Under normal circumstances, the chain 8 is slightly slack, but if abnormal loads occur or the connecting parts become loose, the chain 8 immediately bears force, firmly connecting the jaw body 2 to the rear axle housing, preventing the jaws from falling off or shifting, and ensuring the safety of the wrecker operation.

[0034] In one embodiment, see Figure 1 and Figure 2 As shown, the angle adjustment mechanism 3 includes a ball joint seat 31, which is located between two fourth upright plates 224 and is fixedly connected to the mounting main plate 21. A ball pin 32 is provided at the bottom of the ball joint seat 31. The ball joint seat 31 is fixed between the fourth upright plates 224 on both sides of the mounting main plate 21. It is usually made of high-strength steel or cast steel. The ball joint seat 31 has a hemispherical groove inside to accommodate the ball head part of the ball pin 32. During installation or use, the operator can adjust the jaws in multiple directions by rotating the ball joint seat 31 and the ball pin 32 according to the angle of the tow bar of the disabled vehicle. After the angle is determined, the ball pin 32 can be fixed by the locking nut or locking plate on the outside of the ball joint seat 31 to prevent the angle from changing during operation.

[0035] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
