Description

Technical Field

[0001] This invention relates to the field of mining machinery technology, specifically to a support transport vehicle suitable for steep road surfaces. Background Technology

[0002] Hydraulic supports are core heavy equipment used in underground engineering projects such as coal mines to support roadways and ensure operational safety. Due to their large weight and size, their relocation and transportation rely on specialized support transport vehicles. The operational stability and adaptability of these vehicles directly affect project efficiency and construction safety. Currently, the mainstream support transport vehicles in the industry mainly employ two core transport methods, but both have significant drawbacks under conditions of steep slopes:

[0003] The first type is the hinged lifting type, which uses a hinge linkage mechanism to lift and transport the support. However, its structural design makes it easy for the force on both sides of the support to become unbalanced during the lifting process, which can easily lead to the risk of tipping over. Moreover, the hydraulic support is mainly fixed by workers with chains, which is prone to instability and can easily shake during transportation. The second type is the pallet traction type, which relies on a fixed pallet with rotating rollers to support the support. The support is then pulled to the support plate by a traction device. However, the pallet and the hydraulic support base have poor compatibility and insufficient positioning accuracy. In steep slope environments, the support is prone to sliding back and forth or shifting left and right along the surface of the pallet.

[0004] Both of the aforementioned transport vehicles rely solely on a tractor for traction, resulting in insufficient traction. They are prone to slipping uphill and rolling downhill, and their supports lack stability under load, posing significant safety hazards. They are ill-suited to the transport needs of complex steep slope conditions. In summary, neither of the existing support transport methods can effectively address the core issues of traction supplementation, precise support positioning, and stable load-bearing on steep slopes, thus hindering the operational efficiency and safety of underground engineering projects. Therefore, a new type of support transport vehicle adapted to steep slopes is urgently needed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide a support transport vehicle suitable for steep road surfaces.

[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a support transport vehicle suitable for steep road surfaces, comprising a tractor and a transport vehicle, wherein the tractor and the transport vehicle are articulated together, the tractor pulls the transport vehicle and provides hydraulic power to the transport vehicle;

[0007] The transport vehicle is equipped with a fixed bearing plate and a movable bearing plate on its inner side. The transport vehicle is also equipped with a lifting mechanism and a traction mechanism. The lifting mechanism lifts the hydraulic support, and the traction mechanism pulls the lifted hydraulic support forward. After the hydraulic support is in place, the lifting mechanism places the hydraulic support on the fixed bearing plate and the movable bearing plate.

[0008] The transport vehicle is equipped with an auxiliary drive mechanism, which includes a positioning mechanism, a guide plate, and a pushing mechanism. The positioning mechanism drives the pushing mechanism to move up and down through the guide plate. The transport vehicle has front wheels and rear wheels that rotate on both sides. The pushing mechanism drives the front wheels and rear wheels to rotate through a ratchet structure.

A limiting plate is provided behind the lifting plate, and a sliding column is provided behind the limiting plate. The output end of the hydraulic cylinder is connected to the top of the sliding column. A vertical sliding groove that slides with the sliding column is provided inside the transport vehicle.

[0010] As an improvement: auxiliary frames are installed on both sides of the base of the hydraulic support, and side plates are provided on the auxiliary frames. Multiple rollers are rotatably provided at the bottom of the side plates, and the rollers roll on the lifting plate.

[0011] As an improvement: two sliding plates are symmetrically provided on the rear side of the fixed bearing plate, and the bottom sides of the movable bearing plate slide in cooperation with the sliding plates. The rear side of the fixed bearing plate is provided with a slot, the front side of the movable bearing plate is provided with a locking platform that cooperates with the slot, and the rear side of the movable bearing plate is provided with an extension plate. The extension plate is connected to the inside of the transport vehicle by a pin. The front and rear ends of the base of the hydraulic support are provided with limiting grooves. The fixed bearing plate and the movable bearing plate are respectively provided with limiting platform one and limiting platform two that cooperate with the limiting groove.

[0012] As an improvement: the guide plate and the pushing mechanism are provided in two sets, respectively located at the front wheel and the rear wheel. The pushing mechanism includes a hydraulic cylinder and a plate. The hydraulic cylinder drives the plate to slide at the bottom of the guide plate. Multiple pawls are elastically hinged at the bottom of the plate. Both the front wheel and the rear wheel axle are provided with ratchet wheels that cooperate with the pawls.

[0013] As an improvement: the displacement mechanism includes a motor, a drive shaft and multiple threaded posts. The motor drives the drive shaft to rotate inside the transport vehicle. Multiple worm gears are provided on the drive shaft. The bottom of each threaded post is provided with a worm wheel that meshes with the worm gear. The two guide plates are connected by a connecting plate. Each guide plate has an end plate at its end. Both the connecting plate and the end plate have threaded holes that mate with the threaded posts.

[0014] As an improvement: the plate is provided with multiple sliders that slide in cooperation with the inner groove of the guide plate, one of the sliders is provided with a transmission column, the hydraulic cylinder is fixed inside the transport vehicle and the output end is provided with a drive slot, and the transmission column slides in cooperation with the through hole on the drive slot.

[0015] As an improvement: the bottom of the plate is provided with multiple abutments, a pawl is hinged on the abutment, a stop plate is provided on the pawl, and the front end of the abutment is limited and matched with the stop plate.

[0016] As an improvement: the traction mechanism includes a drum, a pull platform, a hydraulic cylinder, a rotating platform, and a fixed platform. The drum has rotating shafts at both ends that rotate inside the transport vehicle. One end of the pull platform is pinned to the square tube at the front end of the base of the hydraulic support, and the other end is connected to an iron chain wound around the drum. The two ends of the hydraulic cylinder are respectively hinged to the transport vehicle and the rotating platform. The rotating platform and the fixed platform are both rotatably mounted on the rotating shafts. The fixed platform is fixed inside the transport vehicle. A ratchet is fixed on the rotating shaft and a pawl is elastically hinged on it. The inner side of the rotating platform is elastically hinged with a pawl that cooperates with the ratchet. The inner side of the fixed platform is fixed with a ratchet that cooperates with the pawl.

[0017] The advantages of this invention compared to existing technologies are as follows: This invention, through the coordinated design of multiple mechanisms including lifting, traction, auxiliary drive, and stable bearing, systematically solves the core pain points of hydraulic support handling on steep slopes, such as insufficient traction, difficulty in loading and unloading positioning, and easy slippage during transportation. Relying on the various functional mechanisms driven by hydraulic power, it achieves smooth and controllable operation throughout the entire process of support lifting, traction, and fixing, significantly improving the safety, stability, and operational efficiency of handling on steep slopes. It can adapt to complex steep slope environments without additional auxiliary equipment, and its adaptability and practicality are significantly superior to existing technologies. Specifically:

[0018] 1. Driving performance is greatly enhanced. The height of the push mechanism is precisely adjusted by the displacement mechanism, so that the pawl and the wheel ratchet are precisely engaged. The front and rear wheels can be driven independently or synchronously. The hydraulic power is used to supplement the traction force, effectively avoiding wheel slippage and rollover on steep slopes, ensuring smooth driving up and down slopes, and significantly improving the transport vehicle's ability to pass through steep slopes and its reliability.

[0019] 2. Precise and efficient loading and unloading positioning: The symmetrical lifting mechanism ensures balanced force on the support, the roller design reduces movement resistance, and the traction mechanism achieves unidirectional traction and anti-slippage through double ratchet locking. Combined with the slot and limit platform structure of the bearing plate, it achieves precise alignment of the support from lifting, traction to placement, which simplifies the loading and unloading process, reduces the difficulty of operation, and greatly improves the work efficiency.

[0020] 3. Significantly improved transportation stability: The sliding engagement and locking structure of the fixed and movable bearing plates, as well as the interlocking structure of the limiting groove and limiting platform, restricts the forward, backward, left, and right movement of the support. The stabilizing frame forms a rigid constraint on the upper part of the support through the pressure plate, constructing a two-way fixing system. Combined with the turning flexibility of the hinged connection, it ensures that the support does not shift or tip over during transportation on steep slopes, fully guaranteeing the safety of the transportation process.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings.

[0039] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 5 and attached Figure 7 As shown, a support transport vehicle suitable for steep road surfaces includes a tractor 1 and a transport vehicle 2. The tractor 1 and the transport vehicle 2 are hinged together. The tractor 1 pulls the transport vehicle 2 and provides hydraulic power to the transport vehicle 2. The transport vehicle 2 has a fixed bearing plate 21 and a movable bearing plate 4 on its inner side. The transport vehicle 2 also has a lifting mechanism 5 and a traction mechanism 7 on its inner side. The lifting mechanism 5 lifts the hydraulic support 01, and the traction mechanism 7 pulls the lifted hydraulic support 01 forward. After the hydraulic support 01 is in place, the lifting mechanism 5 places the hydraulic support 01 on the fixed bearing plate 21 and the movable bearing plate 4. The transport vehicle 2 has an auxiliary drive mechanism 6 inside. The auxiliary drive mechanism 6 includes a displacement mechanism 61, a guide plate 62, and a pushing mechanism 63. The displacement mechanism 61 drives the pushing mechanism 63 to move up and down through the guide plate 62. The transport vehicle 2 has a front wheel 26 and a rear wheel 27 rotatably mounted on both sides. The pushing mechanism 63 pushes the front wheel 26 and the rear wheel 27 to rotate through a ratchet structure.

[0040] To address the issues of insufficient traction and difficulty in loading, unloading, and positioning of the hydraulic support 01 during transport on steep slopes, the support transport vehicle 2, through the articulated connection between the tractor 1 and the transport vehicle 2 and the collaborative design of multiple mechanisms, achieves convenience and stability in loading and unloading the hydraulic support 01, improving its ability to cope with steep slopes. The articulated connection between the tractor 1 and the transport vehicle 2 ensures steering flexibility during travel, adapting to changes in the route on steep slopes, while also providing continuous and stable hydraulic power to the transport vehicle 2 through the tractor 1, meeting the power requirements of each actuator.

[0041] When it is necessary to load the hydraulic support 01, the hydraulic support 01 is first pulled out of the support position by the transport vehicle 2. Then, the tractor 1 drives the transport vehicle 2 to reverse, so that the hydraulic support 01 is located inside the transport vehicle 2 and behind the fixed bearing plate 21. Then, the lifting mechanism 5 inside the transport vehicle 2 is activated to lift the hydraulic support 01 from the ground, so that it is not in contact with the ground to avoid the risk of slippage caused by the slope. Then, the traction mechanism 7 is activated to pull the lifted hydraulic support 01 forward along the preset path inside the transport vehicle 2 until it reaches the designated bearing position. The movable bearing plate 4 is installed inside the transport vehicle 2. At this time, the lifting mechanism 5 falls back smoothly, and the hydraulic support 01 is accurately placed on the bearing surface composed of the fixed bearing plate 21 and the movable bearing plate 4, completing the loading operation.

[0042] When driving on steep slopes, although the front wheels 26 and rear wheels 27 on both sides of the transport vehicle 2 provide basic support and driving functions, they are prone to insufficient power or slippage when facing steep slopes. At this time, the auxiliary drive mechanism 6 starts to work: the displacement mechanism 61 adjusts the height of the push mechanism 63 through the guide plate 62 according to the road slope and driving conditions, so that the push mechanism 63 is precisely engaged with the ratchet structure of the front wheels 26 and rear wheels 27. Utilizing the unidirectional transmission characteristic of the ratchet structure, the drive mechanism 63 outputs driving force directly to the front wheels 26 and rear wheels 27, providing additional traction for the vehicle, effectively making up for the lack of simple traction power, preventing wheel slippage, and ensuring that the vehicle can smoothly go up or safely go down on steep slopes.

[0043] Combined with appendix Figure 4 and attached Figure 6 As shown, the lifting mechanism 5 is symmetrically arranged inside the transport vehicle 2. The lifting mechanism 5 includes a hydraulic cylinder 51 and a lifting plate 53. The hydraulic cylinder 51 is fixed inside the transport vehicle 2. A limiting plate 52 is provided on the rear side of the lifting plate 53. A sliding column 54 is provided on the rear side of the limiting plate 52. The output end of the hydraulic cylinder 51 is connected to the top of the sliding column 54. A vertical sliding groove 25 that slides with the sliding column 54 is provided inside the transport vehicle 2.

[0044] Combined with appendix Figure 3 and attached Figure 6As shown, auxiliary frames 3 are installed on both sides of the base 02 of the hydraulic support 01. Side plates 31 are provided on the auxiliary frames 3. Multiple rollers 32 and a braking structure that cooperates with the rollers 32 are rotatably provided at the bottom of the side plates 31. The rollers 32 roll on the lifting plate 53.

[0045] The lifting mechanism 5 mainly solves the problems of difficulty in moving the hydraulic support 01 after lifting, high frictional resistance between the support and the lifting components, difficulty in moving smoothly and accurately positioning, and avoids safety hazards caused by force imbalance during the lifting process.

[0046] The lifting mechanism 5 is symmetrically arranged inside the transport vehicle 2, which can ensure that the hydraulic support 01 is lifted with balanced force on both sides. The sliding column 54 slides in conjunction with the vertical sliding groove 25 inside the transport vehicle 2. With the limiting effect of the limiting plate 52, the movement trajectory of the sliding column 54 can be strictly limited to avoid deviation and shaking during the lifting process, and ensure the stability of the lifting direction. The auxiliary frames 3 on both sides of the base 02 of the hydraulic support 01 contact the lifting plate 53 through multiple rollers 32 at the bottom of the side plate 31. The rollers 32 can convert the sliding friction between the support and the lifting plate 53 into rolling friction, reduce the resistance when the traction mechanism 7 pulls the support to move, and allow the support to move smoothly and slowly on the lifting plate 53.

[0047] Before the lifting operation, ensure that the traction mechanism 7 is connected to the hydraulic support 01 and that the roller 32 is in a braking state. The hydraulic cylinder 51 drives the sliding column 54 to slide upward along the vertical sliding groove 25, which drives the lifting plate 53 to rise synchronously. The lifting plate 53 and the roller 32 fit together to support the hydraulic support 01. The limiting plate 52 limits the position of the auxiliary frame 3 to prevent the auxiliary frame 3 and the hydraulic support 01 from shifting laterally during the lifting process, thus providing a stable guarantee for the subsequent placement of the support on the fixed bearing plate 21 and the movable bearing plate 4.

[0048] Combined with appendix Figure 3 and attached Figure 4 As shown, two sliding plates 24 are symmetrically arranged on the rear side of the fixed support plate 21. The bottom sides of the movable support plate 4 slide in cooperation with the sliding plates 24. The rear side of the fixed support plate 21 is provided with a slot 23. The front side of the movable support plate 4 is provided with a locking platform 41 that cooperates with the slot 23. The rear side of the movable support plate 4 is provided with an extension plate 43. The extension plate 43 is connected to the inner side of the transport vehicle 2 by a pin. The front and rear ends of the base 02 of the hydraulic support 01 are provided with limiting grooves 03. The fixed support plate 21 and the movable support plate 4 are respectively provided with limiting platform 1 22 and limiting platform 2 42 that cooperate with the limiting grooves 03.

[0049] The fixed bearing plate 21 and the movable bearing plate 4 mainly solve the problems that the hydraulic support 01 is prone to sliding back and forth and shifting left and right due to the slope when bearing on a large slope road surface, the poor compatibility between the bearing surface and the base 02 leading to inaccurate positioning, the difficulty of the hydraulic support 01 to smoothly transition to the bearing surface during loading and unloading, and the insufficient stability of the hydraulic support 01 under the bearing state, so as to ensure the safety of the support during transportation.

[0050] The fixed bearing plate 21 serves as the core bearing base, while the symmetrically arranged sliding plate 24 on the rear side provides sliding guidance for the movable bearing plate 4. The movable bearing plate 4 is supported by the fixed bearing plate 21 through the sliding cooperation between the bottom two sides and the sliding plate 24, and the precise engagement of the front locking platform 41 with the locking groove 23 on the rear side of the fixed bearing plate 21. This allows the movable bearing plate 4 to cooperate with the fixed bearing plate 21 to provide bearing capacity for the hydraulic support 01. After the hydraulic support 01 is lifted, the movable bearing plate 4 is pushed into the rear side of the fixed bearing plate 21, and the extension plate 43 is connected to the inner through hole of the transport vehicle 2 with a pin to prevent the movable bearing plate 4 from moving. Then, the hydraulic support 01 is slowly lowered, so that the limiting grooves 03 at the front and rear ends of the base 02 of the hydraulic support 01 are respectively engaged with the limiting platform 22 on the fixed bearing plate 21 and the limiting platform 42 on the movable bearing plate 4. The limiting platform is embedded in the limiting groove 03 to form a limiting structure, which can effectively limit the forward and backward sliding and left and right displacement of the hydraulic support 01 during transportation on a steep slope, further improving the bearing stability.

[0051] Combined with appendix Figure 5 Appendix Figure 7 and attached Figure 8 As shown, the guide plate 62 and the pushing mechanism 63 are provided in two sets, respectively located at the front wheel 26 and the rear wheel 27. The pushing mechanism 63 includes a hydraulic cylinder 631 and a plate 633. The hydraulic cylinder 631 is fixed inside the transport vehicle 2. The hydraulic cylinder 631 drives the plate 633 to slide at the bottom of the guide plate 62. The bottom of the plate 633 is elastically hinged with multiple pawls 637. The axles 28 of the front wheel 26 and the rear wheel 27 are provided with ratchet wheels 29 that cooperate with the pawls 637. The transport vehicle 2 is provided with a braking structure that cooperates with the axles 28.

[0052] Combined with appendix Figure 8 and attached Figure 10 As shown, the bottom of the flat plate 633 is provided with multiple abutments 636, a pawl 637 is hinged on the abutment 636, and a stop plate 638 is provided on the pawl 637. The front end of the abutment 636 is limited and engaged with the stop plate 638.

[0053] The auxiliary drive mechanism 6 mainly solves the problems of insufficient traction, wheel slippage, and loss of power when the transport vehicle 2 on steep slopes relies solely on the tractor 1 for traction. It also addresses the issue of the inability to achieve unidirectional drive, which can lead to slippage or power loss when going downhill. The auxiliary drive mechanism 6 provides sufficient power to climb steep slopes without the need for additional vehicle assistance, ensuring driving safety and stability.

[0054] The guide plate 62 and the push mechanism 63 adopt two sets of symmetrical layouts, respectively corresponding to the front wheel 26 and the rear wheel 27. Each set of push mechanism 63 can provide targeted auxiliary drive for the wheel, ensuring that the vehicle is subjected to balanced force and stable drive on steep slopes, and avoiding slippage or deviation caused by single-wheel drive. The guide plate 62 provides precise sliding guidance for the flat plate 633 of the push mechanism 63, strictly limiting the movement trajectory of the flat plate 633, ensuring that the pawl 637 can be precisely aligned and engaged with the ratchet 29 on the axle 28, and avoiding disengagement during the drive process. The hydraulic cylinder 631 serves as the power source for the push mechanism, relying on the hydraulic power output provided by the tractor 1 to drive the flat plate 633 to slide smoothly along the bottom of the guide plate 62. The abutment 636 at the bottom of the flat plate 633 not only provides installation support for the pawl 637, but also cooperates with the abutment plate 638 on the pawl 637 to provide additional support for the pawl 637, ensuring the stability and safety of the pawl 637 when providing driving force to the ratchet 29.

[0055] When the transport vehicle 2 requires additional traction on a steep slope, hydraulic cylinder 631 pushes the flat plate 633 forward along the guide plate 62, causing pawl 637 to precisely engage with ratchet 29. Utilizing the unidirectional transmission characteristic of the ratchet mechanism, pawl 637 generates a positive driving force on ratchet 29, driving axle 28 to rotate, supplementing the vehicle's traction, and thus providing independent hydraulic power to the front wheel 26 and rear wheel 27. When the slope is relatively gentle, the push mechanism 63 at the front wheel 26 and rear wheel 27 is driven in a staggered manner, that is, the push mechanism 63 drives the front wheel 26... When wheel 26 rotates, the push mechanism 63 at the rear wheel 27 is in the reset process. When the push mechanism 63 at the front wheel 26 is in the reset process, the push mechanism 63 at the rear wheel 27 drives the rear wheel 27 to rotate, so that the transport vehicle 2 continues to move forward. When the slope is relatively large, the push mechanisms 63 at the front wheel 26 and the rear wheel 27 are driven synchronously, providing driving force for the front wheel 26 and the rear wheel 27. Before the push mechanism 63 is reset, the braking structure needs to be activated to lock the front wheel 26 and the rear wheel 27 to prevent the wheels from slipping and causing the transport vehicle 2 to slide down the slope.

[0056] Combined with appendix Figure 8 and attached Figure 9As shown, the displacement mechanism 61 includes a motor 611, a drive shaft 613, and multiple threaded posts 616. The motor 611 is fixed inside the transport vehicle 2. The drive shaft 613 and the multiple threaded posts 616 are rotatably mounted inside the transport vehicle 2. The output end of the motor 611 is provided with a gear 612. The drive shaft 613 is provided with a gear 614 that meshes with the gear 612. The drive shaft 613 is provided with multiple worm gears 615. The bottom of the threaded posts 616 is provided with a worm wheel 617 that meshes with the worm gears 615. The two guide plates 62 are connected by a connecting plate 621. The ends of the guide plates 62 are provided with end plates 622. The connecting plate 621 and the end plates 622 are provided with threaded holes that mate with the threaded posts 616.

[0057] Combined with appendix Figure 10 As shown, the plate 633 is provided with a plurality of sliders 634 that slide in cooperation with the inner groove of the guide plate 62. One of the sliders 634 is provided with a transmission column 635. The hydraulic cylinder 631 is fixed inside the transport vehicle 2 and has a drive slot 632 at its output end. The transmission column 635 slides in cooperation with the through hole on the drive slot 632.

[0058] The displacement mechanism 61 mainly solves the problem that the push mechanism 63 and the ratchet 29 on the front wheel 26 and rear wheel 27 are difficult to achieve precise height adaptation according to the slope change and vehicle driving status, which is prone to disengagement, hard collision or excessive tight engagement due to improper meshing clearance. At the same time, it avoids component wear caused by movement deviation and shaking during the lifting adjustment process, and ensures that the auxiliary drive system can work efficiently and stably under different slopes.

[0059] During operation, gear 612 at the output end of motor 611 meshes with gear 614 on drive shaft 613, transmitting power to drive shaft 613 and causing it to rotate. Multiple worm gears 615 mounted on drive shaft 613 rotate synchronously with it, precisely meshing with worm wheels 617 at the bottom of each threaded post 616. Utilizing the speed reduction and torque amplification characteristics of worm gear transmission, not only is the driving force amplified, but the rotational motion of drive shaft 613 is also converted into the synchronous rotation of the threaded posts 616. The end plate 622 and connecting plate 621 at the end of guide plate 62 are both provided with threaded holes adapted to the threaded posts 616. When the threaded posts 616 rotate... When in motion, the threaded transmission structure converts the rotational motion into linear lifting motion of the connecting plate 621, end plate 622, and guide plate 62, thereby driving the push mechanism 63, which cooperates with the guide plate 62, to lift synchronously. The guide plates 62 on both sides are rigidly connected through the connecting plate 621. The symmetrical layout design of multiple worm gears 615 and worm wheels 617 ensures that the rotation angle of all threaded posts 616 is completely consistent, avoiding uneven load or inconsistent height on both sides during the lifting of the guide plate 62. This enables precise adjustment of the height of the push mechanism 63 to adapt to the position of the ratchet 29 under different slopes, ensuring that the pawl 637 and the ratchet 29 can form the best meshing state.

[0060] Multiple sliders 634 on the flat plate 633 slide in the groove on the inner side of the guide plate 62, providing stable guidance for the lifting and lowering of the pushing mechanism 63. The transmission column 635 on one of the sliders 634 slides in the through hole on the drive slot 632 at the output end of the hydraulic cylinder 631. When the displacement mechanism 61 adjusts the guide plate 62 and the lifting and lowering of the pushing mechanism 63, the transmission column 635 can slide adaptively along the through hole without affecting the working position of the hydraulic cylinder 631.

[0061] When no additional traction is required, the displacement mechanism 61 drives the guide plate 62 and the push mechanism 63 to rise, so that the pawl 637 and the ratchet 29 are decoupled. At this time, the front wheel 26 and the rear wheel 27 can rotate freely and are not affected by the push mechanism 63 when rotating, thus enabling the transport vehicle 2 to reverse.

[0062] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 11 Appendix Figure 12 Appendix Figure 13 Appendix Figure 14 and attached Figure 15As shown, the traction mechanism 7 includes a drum 71, a pull platform 72, a hydraulic cylinder 74, a rotating platform 75, and a fixed platform 76. The drum 71 has a rotating shaft 73 at both ends that rotates inside the transport vehicle 2. One end of the pull platform 72 is pinned to the square tube 04 at the front end of the base 02 of the hydraulic support 01, and the other end is connected to an iron chain that is wound around the drum 71. The two ends of the hydraulic cylinder 74 are respectively hinged to the transport vehicle 2 and the rotating platform 75. The rotating platform 75 and the fixed platform 76 are both rotatably mounted on the rotating shaft 73. The fixed platform 76 is fixed inside the transport vehicle 2. A ratchet 731 and a pawl 732 are elastically hinged on the rotating shaft 73. A pawl 751 that cooperates with the ratchet 731 is elastically hinged on the inner side of the rotating platform 75. A ratchet 761 that cooperates with the pawl 732 is fixed on the inner side of the fixed platform 76.

[0063] The traction mechanism 7 mainly solves the problems of insufficient traction force, easy slippage, and unstable traction force transmission when the hydraulic support 01 is pulled. At the same time, it realizes one-way locking during the traction process, avoids the support from sliding when the power fails, and ensures the safety and accuracy of the hydraulic support 01 traction.

[0064] During operation, hydraulic cylinder 74 outputs driving force, pushing the rotating platform 75, which is hinged to it, to rotate around the rotating shaft 73. The pawl 751, which is elastically hinged on the inner side of the rotating platform 75, then engages with the ratchet 731 on the rotating shaft 73, causing the rotating shaft 73 to rotate synchronously, thereby driving the drum 71 to rotate. The drum 71 tightens the wound chain, and through the pull table 72 pinned to the square tube 04, it pulls the lifted hydraulic support 01 to move smoothly forward along the lifting plate 53. During this process, the pawl 732, which is elastically hinged on the rotating shaft 73, slides smoothly along the helical tooth surface of the ratchet 761 on the inner side of the fixed platform 76 without obstructing the movement of the hydraulic support 01. The rotating shaft 73 rotates in the forward direction; when the hydraulic cylinder 74 stops driving or the hydraulic support 01 tends to slip backward due to the steep slope, the pawl 732 and the ratchet 761 quickly engage, and at the same time, the pawl 751 and the ratchet 731 form a double limit, locking the rotating shaft 73 to prevent it from rotating in the reverse direction, preventing the hydraulic support 01 from slipping backward, ensuring that the traction process is stable and controllable. Finally, through the cooperation of various components, the stable traction, one-way locking and anti-slipping of the hydraulic support 01 on the steep slope is achieved, as well as the accurate positioning after traction, providing a reliable guarantee for the subsequent placement of the hydraulic support 01 on the bearing plate and the transportation process.

[0065] Combined with appendix Figure 1 and attached Figure 16 As shown, after the hydraulic support 01 is transported to the transport vehicle 2, a stabilizing frame 8 is installed on the transport vehicle 2. The bottom of the stabilizing frame 8 is bolted to the top of the transport vehicle 2. The stabilizing frame 8 is provided with a pressure plate 81, which is in close contact with the top beam or cover beam of the hydraulic support 01. A threaded post 82 is rotatably provided on the pressure plate 81. The stabilizing frame 8 is provided with a wing plate 83, and the threaded post 82 is engaged with the threaded hole on the wing plate 83.

[0066] After the hydraulic support 01 is positioned on the transport vehicle 2, the stabilizer 8 is placed on the corresponding position on the top of the transport vehicle 2. The bottom of the stabilizer 8 is fastened to the transport vehicle 2 with bolts to ensure that the stabilizer 8 is installed firmly. Then, the pressure plate 81 on the stabilizer 8 is adjusted. During adjustment, the threaded post 82 on the pressure plate 81 is rotated. By utilizing the matching relationship between the threaded post 82 and the threaded hole on the wing plate 83 of the stabilizer 8, the pressure plate 81 is driven to move down and press against the top beam or cover beam surface of the hydraulic support 01 through threaded transmission, forming a rigid constraint on the upper part of the hydraulic support 01. Combined with the limiting effect of the load-bearing plate of the transport vehicle 2 on the base 02 of the hydraulic support 01, the hydraulic support is fixed in both directions on the transport vehicle 2, avoiding the hydraulic support 01 from shifting or tipping over when transported on steep slopes.

[0067] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
