[0002] At present, with the development of technology, the material transportation technology is also constantly progressing. Currently, when carrying out material transportation, it is usually through a winch to pull a transport vehicle for long-distance transportation operations. A winch is a light and small lifting device that winds a steel wire rope or a chain on a drum to lift or tow heavy objects. Moreover, the winch has high versatility, a compact structure, a small volume, a light weight, a large lifting capacity, and is convenient to use and transfer. It is widely used in material lifting or horizontal towing in construction, water conservancy projects, forestry, mines, docks, etc.

[0003] Currently, when using a winch, in order to ensure the stability of the traction steel wire rope, a guiding part is used at its output end for positioning and guiding the output. This results in a large angle between the traction steel wire rope and the guiding part when the winch pays out the rope, greatly increasing the friction of the traction steel wire rope and affecting the service life of the traction steel wire rope.

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] It can be understood that the terms "first", "second", etc. used in the present application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish one element from another.

[0036] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8 shown, in one embodiment, a winch for material traction is proposed, and the winch includes:

[0037] Main frame 1: including an installation table 101 provided on the main frame 1;

[0038] Rewinding mechanism 2: including a winding drum 202 installed on the installation table 101 for winding the traction rope 201, and the output end of the traction rope 201 passes through a guide cylinder 203 fixedly installed on the installation table 101;

[0039] Sliding mechanism 3: Drives reciprocating motion around the winding drum 202 in cooperation with the swinging mechanism 4;

[0040] Transmission mechanism 5: Drives the sliding mechanism 3 to rotate in cooperation with the reciprocating mechanism 6.

[0041] In the actual application of the embodiment of the present invention, as Figure 1 shown, when the external drive drives the winding drum 202 to rotate, at this time, the traction rope 201 is unwound on the winding drum 202. It should be noted here that, as Figure 3 shown, looking from the right side of Figure 3 to the left, when the traction rope 201 is unwound, it exits the winding drum 202 from below. At this time, the winding drum 202 rotates counterclockwise. When the traction rope 201 is about to be unwound for one week, as Figure 4 shown, at this time, through the action of the reciprocating mechanism 6, the transmission mechanism 5 is driven to rotate synchronously with the outside world. As Figure 8 shown, the rotation of the transmission mechanism 5 drives the sliding mechanism 3 to rotate synchronously through the swinging mechanism 4. The rotation of the sliding mechanism 3 drives the winding drum 202 to move in the direction opposite to the axis of the spiral winding of the traction rope 201 on the winding drum 202. It should be noted here that if the traction rope 201 is wound from left to right on the winding drum 202, the axis direction of the spiral winding of the traction rope 201 on the winding drum 202 is horizontally to the right. The movement of the winding drum 202 makes the unwinding direction of the traction rope 201 always remain in the same straight line as the central axis of the guiding cylinder 203, thereby reducing the movement friction of the guiding cylinder 203 on the traction rope 201 and improving the stability of unwinding. When the traction rope 201 is unwound to the other end of the winding drum 202, at this time, through the action of the swinging mechanism 4, the rotation direction of the sliding mechanism 3 is changed, and at the same time, the spiral winding direction of the traction rope 201 on the winding drum 202 is synchronously changed, so that when changing the direction of unwinding, the moving direction of the winding drum 202 is synchronously changed, so that the unwinding direction of the traction rope 201 always remains in the same straight line as the central axis of the guiding cylinder 203, achieving the purpose of automatically changing the moving direction and reducing the wear of the traction rope 201.

[0042] As Figure 3 、 Figure 7 and Figure 8 shown, as a preferred embodiment of the present invention, the sliding mechanism 3 includes a sliding frame 301 rotatably connected to the winding drum 202. Two L-shaped racks 302 are fixedly installed on the surface of the sliding frame 301. Each L-shaped rack 302 is engaged with a rotating gear 303. The sliding frame 301 is slidably connected to the linear slideway 304.

[0043] In the actual application of the embodiment of the present invention, when unwinding for one week, at this time, the transmission mechanism 5 drives the swinging mechanism 4 to rotate. As Figure 3 、Figure 7 and Figure 8 As shown, the rotating gear 303 is driven to rotate. The rotation of the rotating gear 303 drives the L-shaped rack 302 to move in the direction opposite to the axis of the traction rope 201 spirally wound on the winding drum 202 through the gear rack transmission, thereby driving the sliding frame 301 to move leftward on the linear slide 304, so that the unwinding direction of the traction rope 201 and the central axis of the guide cylinder 203 always remain in the same straight line, thereby reducing the movement friction of the guide cylinder 203 on the traction rope 201 and improving the unwinding stability. At the same time, when the traction rope 201 is unwound to the other end of the winding drum 202, the rotation direction of the rotating gear 303 is changed by the action of the swing mechanism 4, thereby driving the sliding frame 301 to move rightward, thereby achieving the purpose of automatically switching the movement direction.

[0044] like Figure 4 , Figure 5 , Figure 6 and Figure 13 As shown, as another preferred embodiment of the present invention, the swing mechanism 4 includes a connecting shaft 405 coaxially fixedly connected to the two rotating gears 303, the connecting shaft 405 is rotatably connected to the mounting platform 101, the surface of the connecting shaft 405 is slidably connected with a swing bevel gear group 402, the swing bevel gear group 402 is provided with two opposing bevel gears, the swing bevel gear group 402 is meshed with the active bevel gear 401, and bevel gear magnets 403 are fixedly installed on the two bevel gears of the swing bevel gear group 402, and two rotating shaft magnets 404 matching the bevel gear magnets 403 are fixedly installed on the surface of the connecting shaft 405, the magnetic properties of the bevel gear magnets 403 and the rotating shaft magnets 404 are different, the swing bevel gear group 402 passes through the linkage fork block 406 and is fixedly connected to the linkage fork block 406, the surface of the linkage fork block 406 is in contact with the toggle cylinder 407, and the toggle A connecting rod 408 is fixedly installed on the surface of the cylinder 407, and a front ramp block 409 and a rear ramp block 410 are fixedly installed on the surface of the connecting rod 408, and the front ramp block 409 and the rear ramp block 410 are rotationally symmetrically arranged. Two thrust rods 411 cooperating with the front ramp block 409 and the rear ramp block 410 are fixedly installed on the surface of the sliding frame 301, and the two thrust rods 411 are symmetrically arranged on the sliding frame 301. The toggle cylinder 407 is fixedly installed on a follow-up slider 412, and the follow-up slider 412 is slidingly connected to the mounting table 101. Two telescopic rods 413 are rotatably installed on the surface of the follow-up slider 412, and the other end of each telescopic rod 413 is rotatably installed on the surface of the fixed block 415. The fixed block 415 is connected to the follow-up slider 412 by a toggle spring 414, and the fixed block 415 is fixedly connected to the surface of the mounting table 101.

[0045] In the actual application of the embodiment of the present invention, when the transmission mechanism 5 drives the driving bevel gear 401 to rotate, the rotation of the driving bevel gear 401 drives the swinging bevel gear set 402 to rotate synchronously, and the rotation of the swinging bevel gear set 402 drives the rotating gear 303 to rotate, thereby driving the winding drum 202 to move through the sliding mechanism 3. When the towing rope 201 is unwound to the other end of the winding drum 202, as Figure 13 shown, due to the synchronous movement of the sliding frame 301, the thrust rod 411 continuously approaches the front slope block 409. When approaching the front slope block 409, from Figure 13 the front view direction, at this time, the front slope block 409 is driven to move obliquely left and downward by the extrusion of the thrust rod 411, as Figure 6 shown, from Figure 6 the front view direction, and then the dialing cylinder 407 is driven to move leftward through the connecting rod 408. During the process of the dialing cylinder 407 moving leftward, the follower slider 412 is driven to move synchronously, as Figure 4 shown. At this time, the telescopic rod 413 between the follower slider 412 and the fixed block 415 is compressed, and at the same time, the dialing spring 414 is also compressed and stores energy. At this time, with the effect of extrusion, when it moves to the extrusion limit of the dialing spring 414, at this time, under the action of the elastic potential energy of the dialing spring 414, the follower slider 412 is driven to move leftward instantaneously, thereby breaking through the magnetic attraction between the bevel gear magnet 403 and the rotating shaft magnet 404 and driving the linkage fork block 406 to move leftward instantaneously. At this time, the bevel gear magnet 403 at the other end of the swinging bevel gear set 402 attracts the rotating shaft magnet 404, and at the same time, the bevel gear at the other end of the swinging bevel gear set 402 meshes with the driving bevel gear 401. At this time, the rotation of the driving bevel gear 401 drives the connecting rotating shaft 405 to reverse through the swinging bevel gear set 402, thereby driving the rotating gear 303 to reverse, so that the winding drum 202 changes the translational movement direction. When it is unwound to the initial end next time, the translational direction of the winding drum 202 is changed again through the action of the thrust rod 411 and the rear slope block 410, so as to achieve automatic switching and reduce the wear of the towing rope 201.

[0046] As Figure 4 shown, as another preferred embodiment of the present invention, the transmission mechanism 5 includes a driven gear 501 coaxially and fixedly connected to the driving bevel gear 401. The driven gear 501 is rotatably connected to the mounting table 101. The driven gear 501 meshes with a driving gear 502. A sliding shaft 503 penetrates through the surface of the driving gear 502 and is slidably connected to the sliding shaft 503. The sliding shaft 503 is coaxially and fixedly connected to a rotating shaft sleeve 504. The other end of the rotating shaft sleeve 504 is coaxially and fixedly installed with a moving gear 505. The moving gear 505 meshes with a driving gear 506 through the drive of a reciprocating mechanism 6.

[0047] In the actual application of the embodiment of the present invention, when the winding drum 202 rotates close to one week, asFigure 4 As shown in the figure, at this time, the reciprocating mechanism 6 makes the moving gear 505 engage with the driving gear 506. Then, the external drive drives the moving gear 505 to rotate. The rotation of the moving gear 505 drives the driving gear 502 to rotate synchronously. Then, through the meshing action of the gears, the driving bevel gear 401 is driven to rotate. The driving bevel gear 401 drives the winding drum 202 to perform a translational motion through the transmission from the swing mechanism 4 to the sliding mechanism 3. When the winding drum 202 translates a diameter length of the traction rope 201, at this time, the reciprocating mechanism 6 makes the moving gear 505 disengage from the driving gear 506, so that the winding drum 202 stops moving, achieving the purpose that the winding drum 202 translates a diameter distance of the traction rope 201 for each rotation of the traction rope 201 during unwinding.

[0048] As Figure 4 , Figure 11 and Figure 12 shown, as another preferred embodiment of the present invention, the reciprocating mechanism 6 includes a reciprocating rod 601 that penetrates through the sliding shaft 503, the rotating shaft sleeve 504, and the moving gear 505 and is rotatably connected to the sliding shaft 503, the rotating shaft sleeve 504, and the moving gear 505. The surface of the reciprocating rod 601 is connected to the mounting table 101 through a reciprocating spring 602. The other end of the reciprocating rod 601 is in contact with the inner wall of the chute circular plate 603. The inner wall of the chute circular plate 603 is provided with a spiral groove platform 604 and a flat groove platform 605 that are smoothly connected in sequence and cooperate with the other end of the reciprocating rod 601. The other end of the flat groove platform 605 is connected to the other end of the spiral groove platform 604 through a vertical stepped slope.

[0049] In the actual application of the embodiment of the present invention, when the traction rope 201 is unwound, as Figure 4 shown, at this time, the external drive drives the chute circular plate 603 to rotate. As Figure 12 shown, at this time, the rotation of the chute circular plate 603 makes the reciprocating rod 601 move along the trajectory of the spiral groove platform 604. As Figure 4 shown, from the front view direction of Figure 4 , further, the reciprocating rod 601 moves to the right. The movement of the reciprocating rod 601 drives the moving gear 505 to continuously approach the driving gear 506. When the reciprocating rod 601 runs onto the flat groove platform 605, at this time, the moving gear 505 engages with the driving gear 506. At this time, the external drive drives the transmission mechanism 5 to rotate, and then drives the winding drum 202 to move through the swing mechanism 4 and the sliding mechanism 3, thus achieving the purpose of automatic following translation. After the translation is completed, at this time, the reciprocating rod 601 is reset through the step between the flat groove platform 605 and the spiral groove platform 604, so that the moving gear 505 and the driving gear 506 are no longer engaged, achieving the purpose of automatic synchronous adjustment.

[0050] As Figure 4 ,Figure 9 and Figure 10 As shown in Figure 10 , as another preferred embodiment of the present invention, the winch further includes an oil injection mechanism 7. The oil injection mechanism 7 includes an oil storage cylinder 701 fixedly installed at one end of the reciprocating rod 601. The surface of the oil storage cylinder 701 is slidably connected to the inner wall of the pressure piston 702. The pressure piston 702 is fixedly installed on the mounting table 101. The pressure piston 702 is rotatably connected to the driving gear 502. The surface of the pressure piston 702 is connected to the oil inlet pipe 703. The inside of the pressure piston 702 communicates with the inside of the oil inlet pipe 703. And a one-way valve is installed on the oil inlet pipe 703. An oil outlet pipe 704 is also fixedly installed on the mounting table 101. And the inside of the oil outlet pipe 704 communicates with the inside of the pressure piston 702 through a small hole opened on the mounting table 101. The other end of the oil outlet pipe 704 is fixedly installed with an injector 705. A guiding nozzle 706 is fixedly installed on the surface of the injector 705. A one-way valve is also installed on the oil outlet pipe 704. The other end of the oil inlet pipe 703 is connected to an external fuel tank.

[0051] In the actual application of the embodiment of the present invention, as Figure 4 shown in Figure 4 , when the reciprocating rod 601 moves to the right, at this time the reciprocating rod 601 drives the oil storage cylinder 701 to move synchronously to the right. The rightward movement of the oil storage cylinder 701 squeezes the lubricating oil in the pressure piston 702. As Figure 9 and Figure 10 shown in Figure 10 , the lubricating oil in the pressure piston 702 is transported to the injector 705 through the oil outlet pipe 704, and then sprayed onto the towing rope 201 through the guiding nozzle 706, so as to achieve the purpose of lubricating the surface of the towing rope 201. When the reciprocating rod 601 moves to the left, at this time, due to the function of the one-way valve, lubricating oil is drawn from the external fuel tank through the oil inlet pipe 703, so as to achieve the purpose of automatically adding lubricating oil.

[0052] As Figure 1 shown in Figure 1 , as another preferred embodiment of the present invention, the winch further includes a driving mechanism 8. The driving mechanism 8 includes a driving motor 801 fixedly installed on the mounting table 101. The output end of the driving motor 801 is connected to the input end of the speed reducer 802. The output end of the speed reducer 802 is fixedly installed with an output rotating shaft 803. A driving gear 506 is coaxially fixedly installed on the surface of the output rotating shaft 803. The other end of the output rotating shaft 803 penetrates through the chute circular plate 603 and is connected to a rotating disk 804. And the chute circular plate 603 is fixedly installed on the surface of the rotating disk 804. The rotating disk 804 is slidably connected to the winding drum 202.

[0053] In the actual application of the embodiment of the present invention, as Figure 1As shown, when the unwinding operation is performed, the driving motor 801 starts to operate at this time. The operation of the driving motor 801 drives the output rotating shaft 803 to rotate through the speed reducer 802. The output rotating shaft 803 drives the winding drum 202 and the chute circular plate 603 to rotate synchronously through the rotating disk 804. Then, through the transmission of motion, the coordinated operations of unwinding and translation are completed, achieving the purpose of reducing the wear of the traction rope 201.
