Description
Technical Field
[0001] This utility model belongs to the field of liquid winch technology, specifically relating to a disc brake reinforced hydraulic winch. Background Technology
[0002] Hydraulic winches are typically mounted on vehicles. An engine drives an oil pump, which generates high-pressure oil that passes through a directional valve and a balance valve into a hydraulic motor. The hydraulic motor's rotation drives a reducer assembly, which in turn rotates a drum, enabling the steel wire rope to pull heavy objects. Existing patent CN221397065U discloses a hydraulic winch deployment and retrieval device, including a hydraulic winch body. A positioning box is fixedly connected to the surface of the hydraulic winch body, and the positioning box has a limit mechanism inside. A rotating mechanism is located on one side of the hydraulic winch body. The limit mechanism includes a sliding rod, which is fixedly installed between the left and right sides of the positioning box's inner cavity. Current hydraulic winch deployment and retrieval devices only use a single positioning ring to limit and guide the rope, resulting in poor guiding effectiveness. Since the rope is usually steel wire, it is prone to unraveling when wound around the drum, leading to rope tangling and poor deployment and retrieval efficiency. Therefore, a disc brake reinforced hydraulic winch is needed to overcome these difficulties. Summary of the Invention
[0003] This invention addresses the problems existing in the prior art by designing a disc-type brake reinforced hydraulic winch. This invention uses a rope pressing component to press down on the rope and limit its position, and works in conjunction with a rope guiding component to wind and release the rope, resulting in a neater rope winding.
[0004] The objective of this invention is achieved through the following technical solution: a disc-type brake reinforced hydraulic winch, comprising a main frame, with a hydraulic drive assembly and a reducer assembly respectively disposed on the left and right sides of the main frame, and a roller rotatable relative to the main frame between the hydraulic drive assembly and the reducer assembly, the roller meshing and rotating with the reducer assembly; a transmission shaft for transmission is disposed between the hydraulic drive assembly and the reducer assembly, the reducer assembly comprising a reducer housing, an internal gear ring and a planetary gear assembly, the transmission shaft meshing and rotating with the planetary gear assembly; a clutch assembly is disposed on the side of the reducer housing, and when the clutch assembly is rotated, the internal gear ring moves axially relative to the planetary gear assembly; a rope pressing assembly and a rope guiding assembly are also disposed on the main frame, the rope pressing assembly being disposed near the top of the roller, and the rope guiding assembly being disposed near the front of the roller.
[0005] Preferably, the hydraulic drive assembly is a hydraulic motor, which drives the transmission shaft to rotate when it is working; the internal gear ring is disposed inside the reducer housing and is disposed adjacent to the clutch assembly; the transmission shaft meshes with the planetary gear assembly, and the planetary gear assembly meshes with the roller to rotate.
[0006] Preferably, the clutch assembly is installed on the side of the reducer housing and faces the internal gear ring; the clutch assembly includes a clutch base, a clutch pin, and an eccentric handle; the clutch base is fixedly installed on the reducer housing, and the clutch pin is inserted inside the clutch base; the end of the clutch pin is provided with an eccentric handle hinged thereto, and when the eccentric handle is rotated, the clutch pin moves axially relative to the internal gear ring; a first spring for resetting is provided between the clutch pin and the clutch base.
[0007] Preferably, a positioning pin is provided between the clutch pin and the eccentric handle to hinge the two; the eccentric handle is cylindrical, and the outer diameter of the eccentric handle is greater than the distance between the positioning pin and the end of the clutch pin; when the eccentric handle is rotated, the clutch pin moves axially relative to the internal gear ring; the internal gear ring is provided with a plurality of annularly distributed limiting holes, and the outer contour of the limiting holes is adapted to the outer contour of the clutch pin.
[0008] Preferably, the clutch pin is provided with an annular step, one end of the first spring abuts against the annular step, and the other end of the first spring abuts against the inner wall of the clutch base.
[0009] The clutch assembly has two modes: neutral and working. When the clutch assembly is in the working position, the eccentric handle is coaxial with the clutch pin, and the clutch pin is engaged in the limiting hole of the internal gear ring. At this time, the internal gear ring cannot rotate relative to the reducer housing. When the hydraulic drive assembly is working, it drives the transmission shaft to rotate, which in turn drives the planetary gear assembly to rotate, which in turn drives the roller to rotate. Thus, the clutch assembly is in the working position. When it is necessary to switch the clutch assembly from the working position to neutral, the eccentric handle is rotated so that it is perpendicular to the clutch pin. Since the outer diameter of the eccentric handle is larger than the distance between the locating pin and the end of the clutch pin, rotating the eccentric handle allows the clutch pin to disengage from the limiting hole of the internal gear ring. At this time, the internal gear ring can rotate relative to the reducer housing. When the transmission shaft rotates, the planetary gear assembly will be in an idle state. When the hydraulic drive assembly is working, the roller cannot rotate, and the clutch assembly is in the neutral state.
[0010] Preferably, the rope pressing assembly includes a pressure plate body and a pair of tension springs. The pressure plate body is provided with a pair of connecting parts. The connecting parts are elongated, with one end of the connecting part hinged to the main frame and the other end of the connecting part having a tension spring between it and the main frame. The pressure plate body is fitted to the rope on the roller.
[0011] Preferably, the main frame is provided with a first pin near the rear of the roller, and the connecting part is hinged to the first pin; the top of the main frame is provided with a second pin, and a tension spring is provided between the connecting part and the second pin; the pressure plate body is provided with a guide part towards the end of the guide rope assembly, and the guide part is inclined to the pressure plate body.
[0012] The second pin is positioned higher than the first pin, ensuring the tension spring always holds the end of the connector, thus keeping the pressure plate body in close contact with the rope on the roller. When the rope on the roller is retracted or extended, it remains between the pressure plate body and the roller, preventing tangling and ensuring more even tension. The guide section further prevents excessive wear between the rope and the pressure plate body.
[0013] Preferably, the guide rope assembly includes a guide rope bracket, a long guide roller, and a short guide roller; the long guide roller and the short guide roller are arranged in pairs, each of the long guide rollers is rotatably connected to the guide rope bracket, and each of the short guide rollers is also rotatably connected to the guide rope bracket.
[0014] Preferably, the two long guide rollers are arranged side by side and adjacent to each other, and the two short guide rollers are arranged side by side and opposite to each other; the long guide rollers and short guide rollers are arranged perpendicular to each other, and the long guide rollers and the drum are arranged parallel to each other.
[0015] When the rope is retracted from the drum, it is guided and limited by the long and short guide rollers, which makes the rope less prone to wear and makes the hydraulic winch more stable and reliable during traction.
[0016] Preferably, the main frame includes a pair of front and rear protective plates and left and right protective plates. The front and rear protective plates are fixedly installed on the front and rear sides of the hydraulic winch, and the left and right protective plates are installed on the left and right sides of the hydraulic winch. The left and right protective plates are fixedly connected to the front and rear protective plates, and a bending plate is provided between the two front and rear protective plates to fix them. The bending plate is installed above the drum.
[0017] By installing front and rear guard plates and left and right guard plates, the hydraulic winch has a more stable structure and is safer to use. The front and rear guard plates also facilitate fixing to external structures such as walls or vehicle frames, thus making it easier to secure the hydraulic winch.
[0018] Compared with the prior art, this utility model has the following advantages: 1. By setting a clutch assembly, it is convenient to switch the meshing state of the planetary gear assembly, thereby facilitating gear shifting; the clutch pin can be extended and retracted by the eccentric handle, making the structure simple and reliable; 2. By cooperating with the rope pressing assembly and the rope guiding assembly, the rope on the drum is limited and guided, so that the rope will not be disordered during winding and unwinding, the rope force is more even, and the traction of objects is more reliable; 3. By setting front and rear protective plates and left and right protective plates, the structural strength of the hydraulic winch is increased, and the positioning and installation of the hydraulic winch are also convenient.

A locating pin 65 is provided between the clutch pin 62 and the eccentric handle 63 to hinge them together. The eccentric handle 63 is cylindrical, and its outer diameter is larger than the distance between the locating pin 65 and the end of the clutch pin 62. When the eccentric handle 63 is rotated, the clutch pin 62 moves axially relative to the internal gear ring 32. The internal gear ring 32 is provided with a plurality of annularly distributed limiting holes 9, the outer contour of which is adapted to the outer contour of the clutch pin 62. The clutch pin 62 is provided with an annular step 66, one end of the first spring 64 abuts against the annular step 66, and the other end of the first spring 64 abuts against the inner wall of the clutch base 61.
[0029] The rope pressing assembly 7 includes a pressure plate body 71 and a pair of tension springs 72. The pressure plate body 71 has a pair of connecting parts 73. The connecting parts 73 are elongated, with one end hinged to the main frame 1 and the other end of the connecting part 73 connected to the main frame 1 by a tension spring 72. The pressure plate body 71 is fitted to the rope on the roller 4. The main frame 1 has a first pin 74 near the rear of the roller 4, and the connecting parts 73 are hinged to the first pin 74. The top of the main frame 1 has a second pin 75, and a tension spring 72 is connected between the connecting parts 73 and the second pin 75. The pressure plate body 71 has a guide part 76 at the end of the guide rope assembly 8, and the guide part 76 is inclined to the pressure plate body 71. The rope guide assembly 8 includes a rope guide bracket 81, long guide rollers 82, and short guide rollers 83. The long guide rollers 82 and short guide rollers 83 are arranged in pairs. Each long guide roller 82 is rotatably connected to the rope guide bracket 81, and each short guide roller 83 is also rotatably connected to the rope guide bracket 81. Two long guide rollers 82 are arranged side-by-side and adjacent to each other, and two short guide rollers 83 are arranged side-by-side and opposite to each other.

The bending plate 12 is installed above the drum 4.
[0030] The specific operation process of this embodiment is as follows: The clutch assembly 6 has two modes: neutral and working. When the clutch assembly 6 is in the working position, the position of the eccentric handle 63 is coaxial with the clutch pin 62. At this time, the clutch pin 62 is engaged in the limiting hole 9 of the internal gear ring 32. At this time, the internal gear ring 32 cannot rotate relative to the reducer housing 31. When the hydraulic drive assembly 2 works, it drives the transmission shaft 5 to rotate. When the transmission shaft 5 rotates, it drives the planetary gear assembly 33 to rotate. When the planetary gear assembly 33 rotates, it drives the roller 4 to rotate. Then the clutch assembly 6 is in the working position. When it is necessary to turn the clutch into the working position... When the clutch assembly 6 is switched from the working position to neutral, the eccentric handle 63 is rotated so that the eccentric handle 63 is perpendicular to the clutch pin 62. Since the outer diameter of the eccentric handle 63 is larger than the distance between the end of the positioning pin 65 and the clutch pin 62, the clutch pin 62 can disengage from the limiting hole of the internal gear ring 32 when the eccentric handle 63 is rotated. At this time, the internal gear ring 32 can rotate relative to the reducer housing 31. When the transmission shaft 5 rotates, the planetary gear assembly 33 will be in an idle state. At this time, the roller 4 cannot rotate when the hydraulic drive assembly 2 is working, and the clutch assembly 6 is in the neutral state.
[0031] The second pin 75 is positioned higher than the first pin 74, ensuring that the tension spring 72 always holds the end of the connecting part 73, thus keeping the pressure plate body 71 in close contact with the rope on the roller 4. When the rope on the roller 4 is retracted or extended, it remains between the pressure plate body 71 and the roller 4, preventing tangling and ensuring more even tension. The guide part 76 further prevents excessive wear between the rope and the pressure plate body 71.
[0032] When the rope is retracted from the drum 4, it is guided and limited by the long guide roller 82 and the short guide roller 83, which makes the rope less prone to wear and makes the hydraulic winch more stable and reliable during traction.
[0033] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
