The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0042] Please refer to the instruction manual Figure 1-12 In order to solve the problem that the towing control system is usually implemented by using a sprocket drive, the chain needs a tensioning mechanism, which increases the complexity of the mechanism, the present invention discloses a double winch drive trailer system, including a winch 101, a wire rope 102, a lifting component 104 and a rail 105, the lifting component 104 is slidably arranged on the rail 105, the lifting component 104 is used to lift the car 103, the winch 101 is provided with two, the two winches 101 are respectively arranged at the head and tail ends of the rail 105, the wire rope 102 is connected to the two winches 10 1, the wire rope 102 is connected to the lifting assembly 104; when working, the two winches 101 are driven by the two wire ropes 102. Compared with the sprocket drive method, one winch 101 is added, but when the car 103 moves, one wire rope 102 is used as power and the other wire rope 102 is used as stability control. The two winches 101 cooperate with each other, which is easy to install and stable in operation. Compared with the chain, the wire rope 102 is light in structure and easy to maintain. The wire rope 102 also reduces the chain detachment and chain jamming when the chain is used.

[0043] Furthermore, the dual winch drive method used in the present invention does not require the provision of a tensioning mechanism and is structurally simple.

[0044] When the double winches drive the car 103, the lifting assembly 104 is lifted under the car 103, the lifting assembly 104 is connected to the wire rope 102, and the winch 101 is started to reel in the wire rope 102, so that the lifting assembly 104 rolls along the rail 105, achieving the purpose of towing the car 103.

[0045] It should be noted that the lifting assembly 104 can use a common mobile cart in the prior art, which will not be described in detail here.

[0046] The present invention also provides a technical solution: a double winch, comprising:

[0047] The winch 101 includes a bracket 1, and two brackets 1 are provided. A bearing seat 2 is fixedly installed on the upper end of one of the brackets 1, and a reducer 10 is fixedly installed on the upper end of the other bracket 1. The input shaft of the reducer 10 is connected to a first motor 7, and the output shaft of the reducer 10 is connected to a rotating shaft 3. The end of the rotating shaft 3 away from the reducer 10 is rotatably connected to the bearing seat 2, and a retracting roller 4 is fixedly installed on the outer ring of the rotating shaft 3; when working, when the first motor 7 starts to drive the reducer 10 to run, the reducer 10 converts the rotational force speed of the first motor 7 into a suitable speed and drives the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, the retracting roller 4 also rotates synchronously, thereby retracting and releasing the wire rope 102.

[0048] In actual use, a spiral groove 5 is provided at the outer ring of the retractable roller 4. When the retractable roller 4 retracts and releases the steel wire rope 102, the steel wire rope 102 can be retracted and released along the spiral track of the spiral groove 5. When retracting and releasing, the steel wire rope is rolled more neatly and is not easy to be scattered.

[0049] Considering that when the retractable roller 4 needs to stop rotating, the rotating structure is braked by the brake disc, which causes great wear and reduces the service life of the structural parts. Therefore, in the present invention, a brake mechanism 11 is provided at the connection between the first motor 7 and the reducer 10. The brake mechanism 11 includes a brake frame 13 and an electromagnet 15. A power shaft 18 is provided on the first motor 7. The power shaft 18 is fixedly connected to the input shaft of the reducer 10. A protective sleeve 12 is provided on the outer ring of the power shaft 18. The brake frame 13 is provided on the protective sleeve 12. The inner walls on both sides of the brake frame 13 are fixedly connected to the corresponding electromagnets 15. The electromagnets 15 are close to the protective sleeves. A soft pad 16 is fixedly provided on one side of the outer ring of the sleeve 12, and two magnetic blocks 17 are fixedly provided on the outer ring of the power shaft 18, and the magnetic blocks 17 correspond to the electromagnets 15. The bottom of the brake frame 13 is fixedly installed on the mounting platform 14, and the mounting platform 14 is fixedly installed on the bracket 1; when it is necessary to stop the retractable roller 4, the electromagnet 15 is started, and the electromagnet 15 generates magnetism. After the electromagnet 15 generates magnetism, it repels or attracts the magnetic blocks 17, so that the two magnetic blocks 17 are respectively away from or close to the electromagnet 15. When the magnetism increases to a certain extent, the rotational force of the power shaft 18 is offset. When the rotational force of the power shaft 18 disappears, the retractable roller 4 stops.

[0050] The present invention utilizes magnetic control to achieve the purpose of braking the retractable roller 4. The braking is contactless and there is no wear between the structural parts, which can increase the service life of the structural parts. There is no noise or high heat generated during braking, which is simple and practical.

[0051] It should be noted that those skilled in the art can select a magnetic block 17 with appropriate magnetism according to actual needs, or change the strength of the magnetism generated by the electromagnet 15 by controlling the current passing through the electromagnet 15, thereby facilitating the control of the speed at which the retractable roller 4 is braked.

[0052] The soft pad 16 replaces the electromagnet 15 in contact with the protective cover 12, and has a good buffering effect to avoid structural damage due to vibration between structures; the magnetic block 17 and the power shaft 18 are protected in the protective cover 12 and do not contact other structures, so it is not easy to cause accidents during braking.

[0053] Because the wire rope 102 is retracted and released by the retracting roller 4, in order to prevent the wire rope roll on the retracting roller 4 from having an excessively large diameter and causing wear from contact with the ground, a lower baffle 6 is fixedly connected between the two brackets 1. The lower baffle 6 is located below the retracting roller 4. The retracting roller 4 can be used to limit the diameter of the wire rope roll to prevent the wire rope roll from having an excessively large diameter.

[0054] In actual use, the length of the wire rope is fixed, and as long as the distance between the reel 4 and the lower baffle 6 is set appropriately, the wire rope roll diameter can be prevented from being too large and contacting the ground; however, if the wire rope roll becomes scattered when being reeled, the wire rope 102 is likely to be repeatedly wound around the same area on the reel 4, which will cause the wire rope roll diameter to be too large and contact the ground. The lower baffle 6 provided in the present invention can effectively prevent the wire rope roll diameter from being too large and contacting the ground. When the wire rope roll is too large and contacts the lower baffle 6, the blocking effect of the lower baffle 6 will cause the wire rope 102 to be wound around other areas on the reel 4.

[0055] Moving wheels 9 are provided at the bottom of both ends of the bracket 1, and a second motor 8 is provided on the side of one of the moving wheels 9. The second motor 8 is fixedly mounted on the corresponding bracket 1. The moving wheels 9 can roll on the ground to facilitate the movement and fixation of the bracket 1.

[0056] In order to keep the wire rope 102 in a horizontal state at all times, a thickness sensor 19 for monitoring the thickness of the wire rope roll on the retracting roller 4 is fixedly installed on the side of one of the brackets 1, and a hollow cavity 21 is arranged inside the bracket 1, and an electric push rod 20 is fixedly installed inside the upper end of the hollow cavity 21, and the electric push rod 20 is arranged vertically, and the lower end of the electric push rod 20 is fixedly connected to a moving wheel mounting seat 22, and the moving wheel 9 is rotatably arranged on the moving wheel mounting seat 22; when the thickness sensor 19 detects that the diameter of the wire rope roll on the retracting roller 4 is too large or too small, the electric push rod 20 is started accordingly, so that the bracket 1 rises or falls, thereby keeping the wire rope 102 in a horizontal state at all times, minimizing the tension on the wire rope 102, increasing the service life of the wire rope 102, and reducing energy consumption.

[0057] In order to increase the service life of the wire rope 102, a storage chamber 44 is provided inside the retracting roller 4, and a coolant is provided in the storage chamber 44. The coolant can cool the wire rope 102, thereby increasing the service life of the wire rope 102; and the spiral groove 5 on the surface of the retracting roller 4 can increase the contact area between the wire rope 102 and the surface of the retracting roller 4, thereby increasing the cooling efficiency of the wire rope 102.

[0058] Connecting tubes 24 are provided at both ends of the retracting roller 4, and the connecting tubes 24 are connected to the storage chamber 44. A guide tube 26 is provided at the end of the connecting tube 24 away from the retracting roller 4. The guide tubes 26 are distributed along the length direction of the retracting roller 4. A guide plate 27 is movably sleeved on the guide tube 26. The guide plate 27 is provided with a sliding hole 35 for the guide plate 27 to slide on the guide tube 26. The guide plate 27 is provided with a guide hole 33, and the guide hole 33 is provided for the wire rope 102 to pass through. When the retracting roller 4 retracts and releases the wire rope 102, the wire rope 102 is pulled by the guide hole 33, which makes it easier for the wire rope 102 to be retracted and released more neatly, and the guide plate 27 can slide adaptively on the guide tube 26.

[0059] A first chamber 30 and a second chamber 31 are provided in the guide tube 26. The first chamber 30 is communicated with one of the connecting tubes 24, and the second chamber 31 is communicated with the other connecting tube 24. A cooling chamber 32 is provided inside the guide plate 27. Connecting holes 28 are provided at both upper and lower ends of the guide tube 26. The connecting holes 28 at both upper and lower ends of the guide tube 26 are communicated with the second chamber 31 and the first chamber 30 respectively. A sealing mechanism 29 is provided in the connecting hole 28. The sealing mechanism 29 includes a substrate 41, a first magnetic plate 40, a rubber sealing block 39 and a spring 42. The rubber sealing block 39 is movably plugged in the connecting hole 28. The substrate 41 is movably attached to the inner wall of the guide tube 26 at the end of the connecting hole 28. The first magnetic plate 40 is fixedly provided on the surface of the substrate 41. The spring 42 is fixedly connected between a side of the substrate 41 away from the rubber sealing block 39 and the inner wall of the guide tube 26. A docking hole 37 is provided on the inner wall of the cooling chamber 32. The docking hole 37 is connected between the corresponding connecting hole 28 and the cooling chamber 32. A one-way valve 38 is arranged in the docking hole 37, and a second magnetic plate 36 is arranged at one end of the docking hole 37 away from the connecting hole 28. The second magnetic plate 36 is fixedly connected to the inner wall of the cooling chamber 32, and the second magnetic plate 36 and the first magnetic plate 40 repel each other away from each other; a plurality of connecting holes 28 are arranged, and the plurality of connecting holes 28 are distributed at equal distances; a rotating ring 25 is connected to the connecting pipe 24, and an annular chamber 47 is arranged inside the rotating ring 25, and a connecting rotating ring 25 is arranged at the inner circle of the rotating ring 25. The connecting groove 46 inside and outside the ring 25, the rotating ring 25 is rotatably set on the outer ring of the retracting roller 4, and a raised ring structure 49 is fixedly set on the outer ring of the retracting roller 4. The rotating ring 25 is rotatably set on the raised ring structure 49, and an annular groove 43 is set on the inner wall of the retracting roller 4 corresponding to the position of the inner ring of the raised ring structure 49. A plurality of circular holes 45 distributed in a circular array are set in the annular groove 43, and the circular holes 45 are connected to the connecting groove 46. A water pump 48 is set between the connecting pipe 24 and the annular chamber 47.

[0060] During operation, when the guide plate 27 moves to the corresponding connecting hole 28, the second magnetic plate 36 repels the first magnetic plate 40, so that the rubber sealing block 39 moves out of the connecting hole 28, so that the corresponding docking hole 37 and the connecting hole 28 can be connected; when the water pump 48 is started, the coolant can circulate through one of the connecting pipes 24, the annular chamber 47, the connecting groove 46, the circular hole 45, and the storage chamber 44 in turn and then enter the other connecting pipe 24. The coolant entering the other connecting pipe 24 passes through the second chamber 31, the corresponding connecting hole 28, the cooling chamber 32 and the first chamber 30 in turn and then enters the original connecting pipe 24 again, thereby achieving the purpose of circulating heat dissipation of the wire rope 102, and the coolant absorbs the heat at the outer ring of the wire rope 102, accurately dissipates heat, and improves the heat dissipation effect.

[0061] In actual use, a refrigerator or other device may be provided in the storage chamber 44 or other locations to cool the coolant, which is a common technology and will not be described in detail here; rubber pads 34 are provided at both ends of the guide plate 27 to seal the ends of the sliding hole 35. The one-way valve 38 is provided to prevent the coolant from flowing back.

[0062] It is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
