Description

Technical Field

[0001] This utility model relates to the technical field of tracked flatbed trucks, specifically to a hydraulic winch for mining tracked flatbed trucks. Background Technology

[0002] In industrial sectors such as mining, tracked flatbed trucks play a crucial role in transporting various materials and equipment, with frequent demands for pipe transportation and laying. Traditional methods of transporting mining pipes, when combined with tracked flatbed trucks, present numerous inconveniences and drawbacks.

[0003] In terms of pipe securing, traditionally, simple rope bindings or basic clamps were used to secure pipes to transport vehicles. This method is unreliable; when flatbed trucks travel on bumpy mining roads, vibrations and shaking can easily cause pipes to loosen and fall off. Once a pipe falls off, it not only interrupts ongoing work processes and affects project progress but also poses a serious safety threat to surrounding personnel and equipment, causing collisions, damage, and other accidents, increasing additional maintenance costs and time losses. In the pipe guiding stage, there is a lack of specially designed and efficient guiding devices. During pipe deployment and retraction operations, the absence of a precise guiding mechanism makes the pipes prone to misalignment, tangling, and other problems. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic pipe winding winch for mining tracked flatbed trucks, so as to facilitate the fixing and guiding of pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic winch for mining tracked flatbed trucks, comprising a tracked flatbed truck body, a controller disposed on the surface of the tracked flatbed truck body, and a winch assembly disposed on the top of the tracked flatbed truck body, the winch assembly comprising: a winch component disposed on the top of the tracked flatbed truck body; and a guide component disposed on one side of the winch component.

[0006] Preferably, the retraction component includes: a support frame, fixedly installed on the surface of the tracked flatbed vehicle body; and a hydraulic motor, fixedly installed on the surface of the tracked flatbed vehicle body.

[0007] Preferably, the output end of the hydraulic motor is provided with a short shaft, and the other end of the short shaft is fixedly fitted with a pulley. The two sides of the support frame are respectively rotatably connected to the connecting shafts through bearings. A winch is fixedly installed between the connecting shafts. A pulley is fixedly fitted on the outer wall of one of the pulleys. The pulley is connected to the pulley one through belt drive. A connection port is opened on one side of the winch.

[0008] The transmission system, consisting of pulley one on the short shaft of the hydraulic motor output end, pulley two on the winch connecting shaft, and the belt in between, can effectively transmit the power generated by the hydraulic motor to the winch.

[0009] Preferably, an arc-shaped connecting block is fixedly installed on one side of the winch, and a U-shaped fixing plate is fixedly installed on one side of the winch. A threaded rod is threadedly connected to the inside of the U-shaped fixing plate, and a rotating block is fixedly installed at the outer end of the threaded rod. The other end of the threaded rod is rotatably connected to the arc-shaped fixing block through a bearing. A locking block is symmetrically fixedly installed on the inner side of the arc-shaped fixing block, and a locking groove is opened on the outer side of the arc-shaped connecting block. The locking block is engaged with the arc-shaped connecting block through the locking groove.

[0010] The rotating block drives the threaded rod to rotate inside the U-shaped fixing plate, bringing the arc-shaped fixing block closer to the arc-shaped connecting block. By using the engaging connection between the engaging block and the engaging groove, the pipe can be tightly clamped between the arc-shaped connecting block and the arc-shaped fixing block.

[0011] Preferably, the guide component includes: a fixing plate, symmetrically fixedly installed on the surface of the tracked flatbed vehicle body; and a motor, fixedly installed on the outside of the fixing plate.

[0012] Preferably, a reciprocating threaded rod is movably arranged between the fixed plates. The two ends of the reciprocating threaded rod respectively movably pass through the inner side of the fixed plate and extend to the outer side of the fixed plate, and are rotatably connected to the fixed plate through bearings. The output end of the motor is connected to one end of the reciprocating threaded rod. A movable block is threadedly connected to the outer wall of the reciprocating threaded rod, and a support rod is fixedly installed on the top of the movable block.

[0013] The motor drives the reciprocating threaded rod to rotate. Since the movable block is threadedly connected to the reciprocating threaded rod, the movable block can perform linear reciprocating motion on the reciprocating threaded rod.

[0014] Preferably, a connecting frame is fixedly installed on the top of the support rod, a fixed shaft is fixedly installed between the connecting frames, a guide roller is movably sleeved on the outer wall of the fixed shaft, sliding openings are symmetrically opened on both sides of the connecting frame, a fixed shaft is slidably connected to the connecting frame through the sliding opening, a guide roller is movably sleeved on the outer wall of the fixed shaft, and a fixed top plate is fixedly installed symmetrically on both sides of the connecting frame.

[0015] The lower guide roller on fixed shaft one and the upper guide roller on fixed shaft two form an upper and lower clamping structure to precisely guide the pipe.

[0016] Preferably, connecting plates are fixedly installed at both ends of the second fixed shaft, and a guide rod is fixedly installed at the top of the connecting plate. The top end of the guide rod movably passes through the bottom of the fixed top plate and extends to the top of the fixed top plate, and a limiting circular plate is fixedly installed thereon. A spring is sleeved on the outer wall of the guide rod, and one end of the spring is fixedly connected to the fixed top plate, and the other end of the spring is fixedly connected to the fixed top plate.

[0017] The spring always applies a spring force to the upper guide roller, so that the upper guide roller and the lower guide roller maintain a certain clamping force on the tube.

[0018] This utility model provides a hydraulic winch for mining tracked flatbed trucks. It has the following advantages:

[0019] (1) This utility model places one end of the pipe at the arc-shaped connecting block, and then rotates the rotating block to drive the threaded rod to rotate. Since the threaded rod is threadedly connected to the U-shaped fixing plate, and the other end of the threaded rod is rotatably connected to the arc-shaped fixing block through the bearing, as the threaded rod rotates, the arc-shaped fixing block will move closer to the arc-shaped connecting block, and the locking block on the inner side of the arc-shaped fixing block will be locked into the locking groove on the outer side of the arc-shaped connecting block, thereby firmly fixing the pipe on the winch and achieving the effect of ensuring that the pipe will not fall off during the pipe winding and unwinding process.

[0020] (2) This utility model is started by a motor on the outside of the fixed plate, which drives the reciprocating threaded rod to rotate. Since the movable block is threadedly connected to the reciprocating threaded rod, and the top of the movable block is connected to the connecting frame through a support rod, the movable block will move back and forth in a straight line along the reciprocating threaded rod under the rotation of the reciprocating threaded rod, thereby driving the connecting frame and the guide rollers on it to move back and forth. The connecting frame is movably sleeved on the outer wall of the fixed shaft one inside the connecting frame, and the guide upper roller is movably sleeved on the outer wall of the fixed shaft two. In the initial state, the spring is in the natural state, so that the guide upper roller and the guide lower roller are in contact, so as to guide the pipe. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] Example 1:

[0031] A preferred embodiment of the hydraulic winch for mining tracked flatbed trucks provided by this utility model is, for example... Figure 1-4The following is an illustration: A hydraulic winch for mining tracked flatbed trucks, comprising a tracked flatbed truck body 1, a controller 2 mounted on the surface of the tracked flatbed truck body 1, and a winch assembly 3 mounted on the top of the tracked flatbed truck body 1. The winch assembly 3 includes: a winch component 31 mounted on the top of the tracked flatbed truck body 1; and a guide component 32 mounted on one side of the winch component 31. The winch component 31 includes: a support frame 311 fixedly mounted on the surface of the tracked flatbed truck body 1; and a hydraulic motor 312 fixedly mounted on the surface of the tracked flatbed truck body 1. The output end of the hydraulic motor 312 is provided with a short shaft 313, and the other end of the short shaft 313 is fixedly fitted with a pulley 314. The two sides of the support frame 311 are respectively rotatably connected to connecting shafts 315 via bearings, and a winch 3 is fixedly mounted between the connecting shafts 315. 18. One of the pulleys 316 has a pulley 316 fixedly sleeved on its outer wall. The pulley 316 is connected to the pulley 314 via a belt 317. A connection port is opened on one side of the winch 318. An arc-shaped connecting block 319 is fixedly installed on one side of the winch 318. A U-shaped fixing plate 3111 is fixedly installed on one side of the winch 318. A threaded rod 3112 is threadedly connected to the inside of the U-shaped fixing plate 3111. A rotating block 3113 is fixedly installed on the outer end of the threaded rod 3112. The other end of the threaded rod 3112 is rotatably connected to the arc-shaped fixing block 3114 via a bearing. A locking block 3115 is symmetrically fixedly installed on the inner side of the arc-shaped fixing block 3114. A locking groove is opened on the outer side of the arc-shaped connecting block 319. The locking block 3115 is locked and connected to the arc-shaped connecting block 319 through the locking groove.

[0032] Furthermore, in this embodiment, by activating the hydraulic motor 312, the hydraulic motor 312 rotates, driving the short shaft 313 at its output end to rotate. The pulley 314 on the short shaft 313 also rotates accordingly. Since the pulley 314 is connected to the pulley 316 on the connecting shaft 315 via a belt 317, according to the belt 317 transmission principle, the pulley 316 drives the connecting shaft 315 and the winch 318 fixed between the connecting shafts 315 to rotate. When the winch 318 rotates, the pipe can be wound onto the winch 318, achieving the pipe-receiving function. When releasing the pipe, the hydraulic motor 312 reverses, driving the winch 318 to rotate in the opposite direction, causing the pipe wound on the winch 318 to gradually be released. On the side, structures such as the arc-shaped connecting block 319 and the arc-shaped fixing block 3114 are used to fix the starting end of the pipe. One end of the pipe is placed at the arc-shaped connecting block 319, and then the rotating block 3113 is rotated, which drives the threaded rod 3112 to rotate. Since the threaded rod 3112 is threadedly connected to the U-shaped fixing plate 3111, and the other end of the threaded rod 3112 is rotatably connected to the arc-shaped fixing block 3114 through a bearing, as the threaded rod 3112 rotates, the arc-shaped fixing block 3114 will move closer to the arc-shaped connecting block 319. The locking block 3115 on the inner side of the arc-shaped fixing block 3114 will be locked into the locking groove on the outer side of the arc-shaped connecting block 319, thereby firmly fixing the pipe on the winch 318 and ensuring that the pipe will not fall off during the pipe winding and unwinding process.

[0033] Example 2:

[0034] Based on Embodiment 1, a preferred embodiment of the hydraulic winch for mining tracked flatbed trucks provided by this utility model is, for example... Figure 1-4As shown: The guide component 32 includes: a fixed plate 321, symmetrically fixedly installed on the surface of the tracked flatbed vehicle body 1; a motor 322, fixedly installed on the outside of the fixed plate 321; a reciprocating threaded rod 323 movably arranged between the fixed plates 321, with both ends of the reciprocating threaded rod 323 respectively movably penetrating the inner side of the fixed plate 321 and extending to the outer side of the fixed plate 321, and rotatably connected to the fixed plate 321 through bearings; the output end of the motor 322 is connected to one end of the reciprocating threaded rod 323; a movable block 324 is threadedly connected to the outer wall of the reciprocating threaded rod 323; a support rod 325 is fixedly installed on the top of the movable block 324; a connecting frame 326 is fixedly installed on the top of the support rod 325; a fixed shaft 327 is fixedly installed between the connecting frames 326; and a guide lower part is movably sleeved on the outer wall of the fixed shaft 327. The roller 328 and the connecting frame 326 have symmetrical sliding openings on both sides. The connecting frame 326 is slidably connected to the fixed shaft 329 through the sliding openings. The outer wall of the fixed shaft 329 is movably fitted with a guide roller 3211. The two sides of the connecting frame 326 are symmetrically fixedly installed with fixed top plates 3213. The two ends of the fixed shaft 329 are respectively fixedly installed with connecting plates 3212. The top of the connecting plate 3212 is fixedly installed with a guide rod 3214. The top end of the guide rod 3214 moves through the bottom of the fixed top plate 3213 and extends to the top of the fixed top plate 3213. A limit circular plate 3216 is fixedly installed thereon. The outer wall of the guide rod 3214 is fitted with a spring 3215. One end of the spring 3215 is fixedly connected to the fixed top plate 3213, and the other end of the spring 3215 is fixedly connected to the fixed top plate 3213.

[0035] Furthermore, in this embodiment, the motor 322 is started, driving the reciprocating threaded rod 323 to rotate. Since the movable block 324 is threadedly connected to the reciprocating threaded rod 323, and the top of the movable block 324 is connected to the connecting frame 326 through the support rod 325, the movable block 324 will reciprocate linearly along the reciprocating threaded rod 323 under the rotation of the reciprocating threaded rod 323, thereby driving the connecting frame 326 and its guide rollers to reciprocate. The connecting frame 326 is movably sleeved on the outer wall of the fixed shaft 327 inside the connecting frame 326, and the upper guide roller 3211 is movably sleeved on the outer wall of the fixed shaft 329. In the initial state, the spring 3215 is in the natural state, so that the upper guide roller 3211 and the lower guide roller 328 are in contact to guide the pipe. At the same time, the fixed shaft 327 drives the connecting plate 3212 to move upward through the fixed shaft 329, and compresses the spring 3215, thus making it suitable for pipes of different sizes.

[0036] In use, when pipe retraction is required, controller 2 activates hydraulic motor 312. The rotation of hydraulic motor 312 drives the short shaft 313 at its output end to rotate, causing pulley 314 on the short shaft 313 to rotate as well. Since pulley 314 is connected to pulley 316 on connecting shaft 315 via belt 317, according to the transmission principle of belt 317, pulley 316 drives connecting shaft 315 and winch 318 fixed between connecting shafts 315 to rotate. When winch 318 rotates, the pipe can be wound onto winch 318, achieving the pipe retraction function. When releasing the pipe, hydraulic motor 312... 12. Reversing the rotation causes the winch 318 to rotate in the opposite direction, gradually releasing the pipe wound on the winch 318. On one side of the winch 318, structures such as the arc-shaped connecting block 319 and the arc-shaped fixing block 3114 are used to fix the starting end of the pipe. Place one end of the pipe on the arc-shaped connecting block 319, and then rotate the rotating block 3113, causing the threaded rod 3112 to rotate. Since the threaded rod 3112 is threadedly connected to the U-shaped fixing plate 3111, and the other end of the threaded rod 3112 is rotatably connected to the arc-shaped fixing block 3114 through a bearing, as the threaded rod 3112 rotates, the arc-shaped fixing block 3114 will move towards the arc-shaped fixing plate 3114. As the connecting block 319 approaches, the engaging block 3115 on the inner side of the arc-shaped fixing block 3114 engages with the engaging groove on the outer side of the arc-shaped connecting block 319, thus firmly fixing the pipe to the winch 318 and ensuring that the pipe will not fall off during the pipe winding and unwinding process. When the pipe winding and unwinding operation is in progress, the motor 322 on the outer side of the fixing plate 321 starts, driving the reciprocating threaded rod 323 to rotate. Since the movable block 324 is threadedly connected to the reciprocating threaded rod 323, and the top of the movable block 324 is connected to the connecting frame 326 through the support rod 325, the movable block 324 will move along the reciprocating threaded rod 323 as the reciprocating threaded rod 323 rotates. The linear reciprocating motion drives the connecting frame 326 and its guide rollers to reciprocate. The connecting frame 326 is movably sleeved on the outer wall of the fixed shaft 327 inside the connecting frame 326, and the upper guide roller 3211 is movably sleeved on the outer wall of the fixed shaft 329. In the initial state, the spring 3215 is in its natural state, so that the upper guide roller 3211 and the lower guide roller 328 are in contact to guide the pipe. At the same time, the fixed shaft 327 drives the connecting plate 3212 to move upward through the fixed shaft 329, and compresses the spring 3215, thus making it suitable for pipes of different sizes.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
