Description

Technical Field

[0001] The present invention relates to the technical field of winches, and more particularly to a multi-functional integrated electric winch. Background Art

[0002] An electric winch is a common mechanical device. Its principle is that a driving device generates power, which is transmitted to a drum through a transmission device, causing the drum to rotate, and the rope or chain is wound or released accordingly, realizing the traction of heavy objects or vehicles. It has the advantages of simple structure and convenient operation, and is widely used in fields such as construction, mining, logistics, vehicle rescue, and outdoor exploration;

[0003] For example, a Chinese patent with the publication number CN222454385U discloses a winch. The power unit of this winch drives the winch drum to rotate through two-stage speed reduction on both sides of a gearbox and a planetary gear transmission. On the one hand, through the two-stage speed reduction of the gearbox and the planetary gear transmission, it is beneficial to reduce the volume of the gearbox, thereby reducing the weight of the electric winch. At the same time, through the two-stage speed reduction of the gearbox and the planetary gear transmission and then driving the winch drum to rotate through the output end, the traction force of the winch can be effectively increased, which is beneficial to expanding the application range of the winch.

[0004] The existing electric winches can reduce the volume of the winch to a certain extent through multi-stage speed reduction for easy carrying and installation. However, during the actual working process of this electric winch, when the steel cable is wound around the drum, there is a risk of mutual entanglement between the steel cables. This will not only increase the wear between the steel cables and shorten the service life of the steel cables, but also the entanglement of the steel cables will affect their secondary release, thereby affecting the working stability of the electric winch.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 8 , the present invention provides a technical solution:

[0034] A multifunctional integrated electric winch includes two groups of parallelly distributed fixing plates 12 and a bushing 37. A drum 22 is rotatably connected between the two groups of fixing plates 12 through the bushing 37. A winch rope 23 is wound around the outer surface of the drum 22. An installation plate 11 is fixedly connected to the outer surface of the rear end of the fixing plate 12. A traction assembly is arranged between the two groups of fixing plates 12;

[0035] The traction assembly includes a reciprocating lead screw 20 rotatably connected to the fixing plate 12. A driving part for driving the reciprocating lead screw 20 to rotate is arranged on the outer side of the reciprocating lead screw 20. A movable seat 21 is in screw transmission connection with the outer surface of the reciprocating lead screw 20. A through hole 25 is formed in the outer surface of the movable seat 21. The winch rope 23 passes through the through hole 25 and penetrates through the front and rear ends of the movable seat 21. The traction assembly is used for guiding the winch rope 23.

[0036] The driving part includes a friction wheel 18 fixedly connected to the outer surface of the reciprocating lead screw 20. A friction groove 19 is formed in the outer surface of the friction wheel 18. A retaining disc 17 is fixedly connected to the outer surface of the drum 22. The number of the retaining discs 17 is two and they are symmetrically distributed left and right. One side of one of the retaining discs 17 is in rotational contact with the outer surface of the friction wheel 18.

[0037] By adopting the above technical solution, an electric winch is a common rescue device for vehicles and ships. When working, the winch rope 23 is wound by the rotation of the drum 22, and the ship and vehicle are pulled by the winch rope 23 to get out of trouble. Two groups of parallel fixed plates 12 rotatably support the drum 22 through the bushing 37, and the mounting plate 11 can keep the position of the fixed plate 12 stable. When the drum 22 winds the winch rope 23, the winch ropes 23 may be entangled and disordered, which will affect the secondary release of the winch rope 23. Therefore, a traction assembly is provided. When the drum 22 winds the winch rope 23, it will drive the retaining disc 17 on its surface to move synchronously. The retaining disc 17 can play a certain limiting role on the winch rope 23, so as to avoid the winch rope 23 contacting the surface of the fixed plate 12. During the rotation of the retaining disc 17, its side wall will rotate and contact with the friction wheel 18. The friction grooves 19 on the surface of the friction wheel 18 can effectively increase the friction force between the friction wheel 18 and the retaining disc 17, so that the retaining disc 17 can drive the friction wheel 18 to rotate. The friction wheel 18 will drive the reciprocating lead screw 20 to rotate synchronously. Symmetrically distributed spiral grooves are provided on the surface of the reciprocating lead screw 20. During rotation, it will drive the movable seat 21 to reciprocate along the axis direction of the reciprocating lead screw 20. The through hole 25 on the surface of the movable seat 21 is used to guide and direct the winch rope 23. By making the pitch of the spiral groove on the surface of the reciprocating lead screw 20 match the rotation speed of the drum 22, during the process of the drum 22 winding the winch rope 23, the movable seat 21 will tractionally adjust the position of the winch rope 23, so that the winch rope 23 can be wound around the outer surface of the drum 22 in sequence, thereby reducing the probability of entanglement and disorder of the winch rope 23 during the winding process to a certain extent, which is beneficial to the secondary release of the winch rope 23, and further effectively improving the stability and reliability during the winding process of the electric winch.

[0038] Specifically, as Figure 4 shown in Figure 7 Figure [not provided in the original, so left as is], a pressure regulating assembly is arranged inside the movable seat 21. The pressure regulating assembly includes a movable groove 24 embedded in the inner side of the movable seat 21. A sliding plate 31 is slidably connected to the inner surface of the movable groove 24. A top rod 32 is fixedly connected to the lower outer surface of the sliding plate 31. A clamping plate 28 is fixedly connected to the lower end of the top rod 32. The clamping plate 28 is arc-shaped and is located above the winch rope 23. The lower outer surface of the clamping plate 28 is in sliding contact with the outer surface of the winch rope 23.

[0039] A limiting plate 29 is fixedly connected to the inner surface of the movable groove 24. The lower end of the top rod 32 penetrates to the lower side of the limiting plate 29 and is slidably connected to the limiting plate 29. An extrusion rod 34 is threadedly connected to the outer surface of the movable seat 21. The outer surface of the extrusion rod 34 is conical. A contact seat 36 is fixedly connected to the upper outer surface of the sliding plate 31. The outer surface of the extrusion rod 34 is in contact with the surface of the contact seat 36.

[0040] The outer surface of the upper end of the contact seat 36 is arc-shaped. A locking sleeve 33 is threadedly connected to the outer surface of the extrusion rod 34. The locking sleeve 33 is in rotational contact with the outer surface of the movable seat 21. A spring 30 is fixedly connected to the outer surface of the lower end of the sliding plate 31. The spring 30 is sleeved outside the ejector rod 32. The lower end of the spring 30 is in contact with the upper surface of the limit plate 29. A knob 35 is fixedly connected to the front end of the extrusion rod 34.

[0041] By adopting the above technical solution, the winch is connected to the trapped vehicle through the winch rope 23 and the tow hook. The winch rope 23 between the winch and the tow hook will sag under the action of gravity. At the moment when the electric winch starts, the winch rope 23 is subjected to a large instantaneous tensile force, which is likely to cause the winch rope 23 to break or be damaged. Therefore, a pressure regulating component is provided. When the traction component guides the winch rope 23, it is necessary to adjust the resistance during the winding and releasing processes of the winch rope 23 so that the winch rope 23 can be kept in a taut state. Therefore, a pressure regulating component is provided. The movable seat 21 slidably supports the sliding plate 31 through the movable groove 24. The lower end of the sliding plate 31 fixedly supports the clamping plate 28 through the ejector rod 32. When it is necessary to increase the friction during the winding and releasing processes of the winch rope 23, the operator rotates the extrusion rod 34 through the knob 35. The extrusion rod 34 will move into the movable groove 24 during rotation due to its threaded connection with the movable seat 21. The surface of the extrusion rod 34 is conical and will be in sliding contact with the contact seat 36 during movement. By extruding the contact seat 36 through the extrusion rod 34, the sliding plate 31 and the clamping plate 28 are driven to move downward synchronously through the contact seat 36. At this time, the lower surface of the clamping plate 28 will be in contact with the surface of the winch rope 23. By changing the position of the clamping plate 28, the friction between the clamping plate 28 and the winch rope 23 can be adjusted, so that the resistance during the winding and releasing processes of the winch rope 23 can be adjusted. Furthermore, the winch rope 23 between the winch and the tow hook can be kept taut, which can reduce the sag amplitude of the winch rope 23 between the winch and the tow hook to a certain extent, thereby reducing the tensile force on the winch rope 23 at the moment when the winch starts, which helps to reduce the risk of the winch rope 23 being broken, and further improves the stability at the moment when the winch starts. After the winch finishes working, the end of the winch rope 23 can be clamped and fixed through the cooperation of the clamping plate 28 and the through hole 25. The movable groove 24 supports the spring 30 through the limit plate 29. When it is necessary to reduce the winding and releasing resistance of the winch rope 23, the operator rotates the extrusion rod 34 in the reverse direction to move the extrusion rod 34 to the outside of the movable seat 21. At this time, the sliding plate 31 will move in the reverse direction and reset under the elastic force of the spring 30. The ejector rod 32 and the clamping plate 28 are driven to move upward through the sliding plate 31, so that the friction between the clamping plate 28 and the winch rope 23 can be reduced. The locking sleeve 33 on the surface of the extrusion rod 34 can play a role in locking and limiting the extrusion rod 34, so that the position of the extrusion rod 34 can be kept stable.

[0042] Specifically, such as Figure 1 And Figure 2As shown, a support assembly is provided between the fixed plates 12. The support assembly includes a pull rod 13 fixedly connected to the two groups of fixed plates 12. Mounting holes 14 are symmetrically formed on the outer surface of the front end of the mounting plate 11. A speed reducer 16 is fixedly connected to the outer surface of the left end of the fixed plate 12. A motor 15 is fixedly connected to the outer surface of the right end of the speed reducer 16. The right end of the output shaft of the motor 15 is fixedly connected to a drum 22 through the speed reducer 16.

[0043] By adopting the above technical solution, the mounting plate 11 is used to fixedly support the two groups of fixed plates 12. The pull rod 13 between the fixed plates 12 can further improve the structural stability of the electric winch. The mounting holes 14 on the surface of the mounting plate 11 can facilitate the rapid installation of the electric winch. When the electric winch works, the output end of the motor 15 outputs power, and the torque is transmitted to the drum 22 through the speed reducer 16, and the winch rope 23 is wound by the drum 22.

[0044] Specifically, as Figure 5 、 Figure 6 shown in Figure 8 As shown, a positioning sleeve 46 is fixedly connected to the outer surface of the right fixed plate 12. A clamping assembly is arranged inside the positioning sleeve 46. The clamping assembly includes a receiving groove 38 embedded in the right end of the drum 22. An adjusting rod 43 is rotatably connected to the inside of the receiving groove 38. The adjusting rod 43 penetrates to the outside of the positioning sleeve 46 and is threadedly connected to the positioning sleeve 46. A magnetic disk 44 is fixedly connected to the outer surface of the adjusting rod 43. An extrusion sleeve 45 is threadedly connected to the outer surface of the adjusting rod 43.

[0045] A fixing groove 40 is fixedly connected to the outer surface of the right end of the drum 22. A pin shaft 42 is fixedly connected to the inner surface of the fixing groove 40. A swing rod 41 is rotatably connected to the outer surface of the pin shaft 42. A clamping block 39 is fixedly connected to the inner surface of the positioning sleeve 46. The swing rod 41 is in clamping contact with the clamping block 39.

[0046] The number of the clamping blocks 39 is several groups and is distributed in a circular array. The outer surface of the clamping block 39 is arc-shaped. The number of the fixing grooves 40, the pin shafts 42 and the swing rods 41 is several groups and is distributed in a circular array. The swing rod 41 is in magnetic attraction contact with the magnetic disk 44.

[0047] By adopting the above technical solution, in order to reduce the torque borne by the motor 15, an engaging component is provided. When the rescue vehicle drags the trapped vehicle through the winch rope 23, the drum 22 needs to remain stationary to prevent the accidental detachment of the winch rope 23. At this time, the operator can rotate the adjusting rod 43. The adjusting rod 43 can move into the positioning sleeve 46 through threaded connection with the positioning sleeve 46. During the movement of the adjusting rod 43, the magnetic disk 44 will be driven to move synchronously. The side of the magnetic disk 44 will slide into contact with the surface of the swing rod 41. The drum 22 is fixedly installed with the pin shaft 42 through the fixing groove 40. The swing rod 41 will rotate with the pin shaft 42 as the fulcrum. When the magnetic disk 44 pushes the swing rod 41, the swing rod 41 will gradually turn to a vertical state. At this time, the swing rod 41 will be engaged between the clamping blocks 39. The cooperation of the swing rod 41 and the clamping blocks 39 can limit the drum 22. When dragging the trapped vehicle through the winch rope 23, the engaging component can effectively share the torque received by the drum 22, thereby reducing the probability of accidental detachment of the winch rope 23, and further effectively improving the safety during the use of the winch. When winding the winch rope 23, the operator operates the adjusting rod 43 and the magnetic disk 44 to move in the reverse direction. The magnetic disk 44 will magnetically pull the swing rod 41, so that the swing rod 41 rotates in the reverse direction and disengages from the clamping block 39.

[0048] Specifically, as Figure 7 shown, a guiding component is arranged inside the movable seat 21. The guiding component includes an installation groove 26 opened at the lower end of the inner surface of the through hole 25. The installation groove 26 is arc-shaped. A plurality of balls 27 are arranged inside the installation groove 26. The outer surface of the upper end of the ball 27 is in rolling contact with the outer surface of the winch rope 23. The number of the balls 27 is several groups and they are evenly distributed inside the installation groove 26.

[0049] By adopting the above technical solution, the movable seat 21 rotatably supports the balls 27 through the installation groove 26. The winch rope 23 will come into contact with the surface of the balls 27 during the winding and releasing processes. Under the guiding action of the balls 27, the smoothness of the winch rope 23 during the winding and releasing processes can be improved, and at the same time, the wear of the winch rope 23 can be reduced to a certain extent.

[0050] For some steel winch ropes 23, the operator injects an appropriate amount of lubricating oil into the installation groove 26. During the winding and releasing processes of the winch rope 23, the lubricating oil will be evenly smeared on the surface of the steel winch rope 23 as the balls 27 rotate. This can not only lubricate the steel winch rope 23, but also effectively reduce the wear and corrosion of the steel winch rope 23, thereby effectively extending the service life of the steel winch rope 23.

[0051] Working principle: When the electric winch works, it pulls the ship and vehicle through the winch rope 23 to get them out of trouble. The retaining disc 17 and the friction wheel 18 will drive the reciprocating lead screw 20 to rotate synchronously. During the rotation of the reciprocating lead screw 20, it will drive the movable seat 21 to reciprocate along the axis direction of the reciprocating lead screw 20. The through hole 25 on the surface of the movable seat 21 is used to guide and direct the winch rope 23, so that the winch rope 23 can be wound around the outer surface of the drum 22 in turn, thus reducing the probability of winding disorder of the winch rope 23 during the winding process to a certain extent. By changing the position of the clamping plate 28, the friction between the clamping plate 28 and the winch rope 23 can be adjusted, so that the resistance during the winding and releasing process of the winch rope 23 can be adjusted, and then the winch rope 23 between the winch and the tow hook can be kept taut. During the winding and releasing process of the winch rope 23, it will contact the surface of the ball 27. Under the guiding action of the ball 27, the smoothness of the winch rope 23 during the winding and releasing process can be improved, and at the same time, the wear of the winch rope 23 can be reduced to a certain extent. The swing rod 41 and the clamping block 39 can play a limiting role on the drum 22. When towing the trapped vehicle through the winch rope 23, the engaging component can effectively share the torque received by the drum 22, thus reducing the probability of accidental detachment of the winch rope 23.
