Description

Technical Field

[0001] This utility model relates to the field of electric winch technology, and in particular to a portable vehicle-mounted electric winch. Background Technology

[0002] With the increasing demand for outdoor off-roading and emergency rescue, portable vehicle-mounted electric winches are increasingly used in complex outdoor environments due to their advantages such as lightweight design and adaptability to multiple scenarios. During the unwinding and towing process, the wire rope is prone to accumulating dust, sand, and other impurities. When winding, these impurities are rolled into the winch body along with the wire rope, which not only causes winding jamming and increases the motor load, but also accelerates the wear of the wire rope surface and shortens its service life. In humid outdoor environments or after being corroded by rain, the wire rope is prone to oxidation and rust, reducing its tensile strength and thus reducing the overall service life of the winch.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1 Reference Figures 1-4 This is the first embodiment of the present invention, which provides a portable vehicle-mounted electric winch. The portable vehicle-mounted electric winch includes a main body component 1, including a base plate 11. The base plate 11 can be connected and fixed to the vehicle frame by bolts. A winding mechanism 12 is provided on one side of the base plate 11. The winding mechanism 12 is relatively narrow. A motor 13 is provided on one side of the winding mechanism 12. A steel wire rope 14 is provided on the winding mechanism 12. The steel wire rope 14 can be wound in multiple layers on the winding mechanism 12. When the motor 13 is started, it can drive the winding mechanism 12 to wind and unwind the steel wire rope 14. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0028] The cleaning assembly 2, located on the base plate 11, includes a cleaning component 21, which is used to clean and oil the wire rope 14, thereby improving the service life of the wire rope 14.

[0029] The cleaning component 21 includes a fixing block 211 fixed to the base plate 11. The fixing block 211 has a through groove, and the steel wire rope 14 is inserted into the through groove. A first ring 212 is connected to the fixing block 211 by a bearing. Several brush heads 213 are fixed inside the first ring 212. The brush heads 213 are distributed circumferentially. A second ring 214 is fixed to one side of the first ring 212. An oiling sponge 215 is fixed inside the second ring 214. The oiling sponge 215 is circular. The brush heads 213 and the oiling sponge 215 can fit against the steel wire rope 14. The first ring 212 and the second ring 214 rotate synchronously, which will drive the brush heads 213 and the oiling sponge 215 to rotate synchronously. During the winding process of the steel wire rope 14, the steel wire rope 14 will first contact the brush head 213 to complete the cleaning, and then pass through the position of the oiling sponge 215 to complete the oiling.

[0030] An oil storage tank 216 is fixed inside the fixing block 211.

[0031] Example 2 Reference Figures 2-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, the cleaning component 2 also includes a transmission component 22 located on the fixed block 211. The transmission component 22 is used to enable the first ring 212 and the second ring 214 to rotate when the wire rope 14 is wound up. The transmission component 22 includes a rotating shaft 221 located on one side of the fixed block 211. A friction wheel 222 is fixed outside the rotating shaft 221. The friction wheel 222 can contact the wire rope 14. Several friction blocks are fixed on the friction wheel 222 to increase the friction between the friction wheel 222 and the wire rope 14, thereby enabling the wire rope 14 to drive the friction wheel 222 to rotate when it is wound up through the through groove of the fixed block 211.

[0033] The fixed block 211 has a bearing connected to a worm 223 inside, and a worm wheel 224 is fixed on the outside of the first ring 212. The worm 223 meshes with the worm wheel 224. The rotation of the worm 223 can drive the worm wheel 224 to rotate, which in turn drives the first ring 212 to rotate, and finally drives the brush head 213 and the oiling sponge 215 to rotate synchronously, thereby achieving the cleaning and oiling of the wire rope 14.

[0034] Specifically, a first pulley 225 is fixed on the rotating shaft 221, and a second pulley 226 is fixed on the worm gear 223. A belt 227 is fitted on the first pulley 225 and the second pulley 226. When the friction wheel 222 rotates, the rotating shaft 221 rotates synchronously, thereby driving the first pulley 225 to rotate. Under the action of the belt 227, the second pulley 226 rotates accordingly, causing the worm gear 223 to rotate.

[0035] Specifically, a support plate 228 is fixed on the fixing block 211. The support plate 228 is in the shape of a semi-circular ring. A scraper 229 is fixed on the support plate 228. The scraper 229 is also in the shape of a semi-circular ring. Its length is shorter than that of the support plate 228 and it is located at the end of the support plate 228 away from the fixing block 211. The support plate 228 and the scraper 229 are chamfered to facilitate scraping off large particles of impurities such as stones adhering to the wire rope 14.

[0036] The position of the scraper 229 will not affect the rotation of the friction wheel 222. The support plate 228 can provide auxiliary support for the wire rope 14, ensuring that the wire rope 14 can fit tightly with the friction wheel 222, thereby smoothly driving the friction wheel 222 to rotate.

[0037] Specifically, a shielding sleeve 2210 is fixed on the fixing block 211. The shielding sleeve 2210 can shield the first pulley 225 and belt 227 to prevent dust and other impurities from affecting the transmission. The rotating shaft 221 is connected to the shielding sleeve 2210 by a bearing. There are two shielding sleeves 2210, which are located on both sides of the rotating shaft 221 to provide stable support and positioning for the rotating shaft 221.

[0038] Example 3 Reference Figures 4-7This is the third embodiment of the present invention, which is based on the first two embodiments.

[0039] Specifically, an oil filling port 216-1 is fixed on the oil storage tank 216, and an oil outlet channel 216-2 is provided at the bottom of the oil storage tank 216. One end of the oil filling port 216-1 extends through to the outside of the fixed block 211, and oil can be added into the oil storage tank 216 through the oil filling port 216-1. A plug is provided on the oil filling port 216-1 to block the oil filling port 216-1, and the oil in the oil storage tank 216 can flow to the oiling sponge 215 through the oil outlet channel 216-2.

[0040] There are two second rings 214, which are fixed by multiple connecting blocks. The connecting blocks are thin and will not contact the bottom of the oil outlet channel 216-2, thus avoiding any impact on the oil outlet channel 216-2 when the second rings 214 rotate. There is a gap between the two second rings 214, and the size corresponds to the oil outlet channel 216-2. The oil in the oil outlet channel 216-2 can also flow into the oiling sponge 215 through the gap. The oiling sponge 215 has good oleophilicity and excellent oily liquid permeability, thus ensuring that the liquid oil can quickly diffuse to other locations.

[0041] Specifically, the cleaning component 2 also includes an auxiliary component 23 located on one side of the oil outlet 216-2. The auxiliary component 23 can control whether the oil outlet 216-2 is unobstructed, thereby preventing the oil in the oil storage tank 216 from flowing out in unnecessary situations.

[0042] The auxiliary component 23 includes a baffle 231 slidably disposed in the oil outlet channel 216-2. The oil outlet channel 216-2 has a moving groove corresponding to the baffle 231. One end of the baffle 231 is fixed with a protrusion to prevent the baffle 231 from falling out of the moving groove. The baffle 231 has an opening 231-1. In the initial state, the opening 231-1 does not coincide with the flow channel of the oil outlet channel 216-2. At this time, the baffle 231 will obstruct the flow of oil. As the baffle 231 moves, when the opening 231-1 coincides with the flow channel of the oil outlet channel 216-2, the oil will flow downward through the opening 231-1 to the oiling sponge 215.

[0043] An extension block 232 is fixed on the baffle 231. The extension block 232, in conjunction with the protrusion on the baffle 231, can limit the extreme position of the sliding of the baffle 231 relative to the oil outlet 216-2, preventing the two from separating. The outer part of the baffle 231 is made of rubber to improve the sealing performance. A first spring 233 is fixed on the extension block 232. The other end of the first spring 233 is fixed to the oil outlet 216-2. The first spring 233 can apply a continuous pushing force to the extension block 232, so that the opening 231-1 does not coincide with the flow channel of the oil outlet 216-2 when there is no other external force, thereby blocking the flow channel of the oil. The first spring 233 is also used for the reset of the baffle 231.

[0044] Specifically, a rotating plate 234 is rotatably mounted on one side of the second ring 214. A rotating shaft 235 is inserted into the rotating plate 234. Support blocks 236 are fixed at both ends of the rotating shaft 235. The support blocks 236 support the rotating shaft 235 and are fixed to the second ring 214. The rotating plate 234 can rotate around the rotating shaft 235. At the same time, the rotation of the second ring 214 can drive the rotating plate 234 to rotate synchronously.

[0045] Specifically, a wedge 237 is fixed to one side of the baffle 231. The wedge 237 has an inclined surface and can contact the rotating plate 234. Under the action of the first spring 233, without other external force, the wedge 237 is located away from the oil outlet 216-2. As the rotating plate 234 rotates, when the rotating plate 234 and the inclined surface of the wedge 237 are in contact, pressure will be applied to the wedge 237, thereby causing the wedge 237 to move closer to the oil outlet 216-2, which in turn drives the baffle 231 to move. The first spring 233 is compressed, and then the opening 231-1 and the flow channel of the oil outlet 216-2 will gradually overlap. The oil can then flow smoothly downward to the oiling sponge 215 to complete the oiling.

[0046] Specifically, a limit plate 238 is fixed on the support block 236. The limit plate 238 is set to restrict the rotating plate 234 to rotate only in one direction. When the wire rope 14 is in the retracted state, it drives the friction wheel 222 to rotate in the forward direction, which in turn drives the second ring 214 to rotate in the forward direction as well. Figure 7 With the mid-angle as a reference, the forward rotation of the second ring 214 will drive the rotating plate 234 to rotate counterclockwise. When the rotating plate 234 rotates to contact the inclined block 237, the limiting plate 238 will restrict the rotating plate 234 from rotating clockwise, thus allowing the rotating plate 234 to squeeze the inclined block 237, thereby compressing the first spring 233 and opening the oil passage.

[0047] When the wire rope 14 is unwound, it drives the friction wheel 222 to rotate in the opposite direction. At this time, the second ring 214 rotates in the opposite direction, which drives the rotating plate 234 to rotate clockwise. Since the limiting plate 238 does not obstruct the counterclockwise rotation of the rotating plate 234, when the rotating plate 234 rotates clockwise with the second ring 214, the rotating plate 234 contacts the inclined block 237. The inclined block 237 will apply a reverse force to the rotating plate 234. At this time, the rotating plate 234 will rotate counterclockwise, but will not push the inclined block 237 to move, and thus will not open the oil flow channel. The baffle 231 always blocks the oil inside the oil tank 216 from flowing downward to the oiling sponge 215.

[0048] A torsion spring 239 is fixed on one side of the rotating plate 234, and the other end of the torsion spring 239 is fixed on the rotating plate 234. The torsion spring 239 is used to make the rotating plate 234 always tend to fit against the limiting plate 238, and to reset the rotating plate 234. When the rotating plate 234 is reset, the first spring 233 will also drive the baffle 231 to reset, thereby blocking the oil outlet 216-2 again to prevent oil from flowing out in unnecessary situations.

[0049] When in use, if the wire rope 14 is in the retracted state, it will drive the friction wheel 222 to rotate, and the rotating shaft 221 will rotate synchronously. This will drive the first pulley 225 to rotate, and under the action of the belt 227, the second pulley 226 will rotate accordingly, causing the worm 223 to rotate. The rotation of the worm 223 can drive the worm wheel 224 to rotate, which in turn drives the first ring 212 and the second ring 214 to rotate. Finally, the brush head 213 and the oiling sponge 215 will rotate synchronously, thereby cleaning and oiling the wire rope 14, extending the service life of the wire rope 14, and reducing the burden on the motor 13.

[0050] Simultaneously, when the wire rope 14 drives the friction wheel 222 to rotate, the rotation of the second ring 214 will cause the rotating plate 234 to rotate counterclockwise. When the rotating plate 234 rotates to contact the inclined block 237, the limiting plate 238 will restrict the rotating plate 234 from rotating clockwise, thus allowing the rotating plate 234 to press against the inclined surface of the inclined block 237, thereby causing the inclined block 237 to move closer to the oil outlet 216-2, which in turn drives the baffle 231 to move, and the first spring 233 is compressed. After the oil is contracted, the opening 231-1 and the oil outlet 216-2 will gradually overlap, allowing the oil to flow smoothly downwards to the oiling sponge 215 and complete the oiling operation. When the wire rope 14 is unwound, the rotation of the rotating plate 234 will not push the inclined block 237 to move, thus preventing the oil outlet from opening. The baffle 231 always blocks the oil inside the oil tank 216 from flowing downwards to the oiling sponge 215, thereby preventing the oil in the oil tank 216 from flowing out in unnecessary situations.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
