Description

Technical Field

[0001] The utility model relates to the technical field of hand winches, in particular to a hand winch driven by a lithium battery tool. Background Technique

[0002] In high-altitude wire erection construction, according to the needs of the installation position, it is necessary to pull the cable to adjust the distance between the cables so as to install them in place. Currently, the commonly used method is to use an externally purchased ordinary hand winch, and manually turn the wrench to gradually pull the cable to adjust the position. Due to the particularity of high-altitude operations, the operator needs to repeatedly turn the wrench for a long time to pull the cable to the required position. The operation is time-consuming and laborious, with low efficiency. The lifting chain is also prone to jamming, and the operator has a high degree of fatigue, and there are also certain safety hazards.

[0003] The gears in the hand winch are important components for operation. The continuous meshing of the teeth between two gears can transmit motion and power. However, when the two gears are meshed, the biting force generated during the meshing process between the teeth is relatively large. This biting force will cause friction on the tooth walls of the teeth, resulting in wear. Over time, the tooth walls of the teeth will show serious wear, causing the distance between the teeth of a single gear to change, which is extremely likely to cause the power to not be normally transmitted through gear meshing, resulting in problems with power transmission. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hand winch driven by a lithium battery tool, which is used to solve the problems existing in the prior art, such as laborious operation, low efficiency, easy jamming of the lifting chain, high fatigue degree of the operator, and certain safety hazards, and also prevent the teeth of the gears from wearing during continuous meshing, extending the service life of the hand winch.

[0005] To achieve the above purpose, the utility model provides a hand winch driven by a lithium battery tool, and the technical solution adopted is: a hand winch driven by a lithium battery tool, including an upper hook, a winch body, a steel wire rope and a lower hook.

The gears in the self-lubricating gear set mesh with each other, and one of the gears is connected to a thread conversion shaft.

A groove is arranged at a position where the oil injection hole is flush with the outer side surface of the wheel body. Both the oil outlet holes and the oil injection hole are connected to the oil storage cavity.

[0008] Preferably, a plug is arranged at the oil injection hole. The plug includes a cap and a cover body. The middle part of the cover body fits with the oil injection hole. The diameters of the upper and lower parts of the cover body are smaller than the middle part. The cap abuts against the inner wall of the groove.

[0026] Embodiment

[0027] The present utility model provides a hand-operated hoist driven by a lithium-ion power tool, as Figure 1-6As shown, it includes an upper lifting hook 1, a hoist body 2, a steel wire rope 4 and a lower lifting hook 5. The lower lifting hook 5 is connected to one end of the steel wire rope 4. The fixed end of the steel wire rope 4 is wound and arranged inside the hoist body 2. The hoist body 2 can control the winding or relaxation of the steel wire rope 4, so as to control the extending length of the steel wire rope 4. The upper end of the hoist body 2 is connected to the upper lifting hook 1. A rotating shaft 17 is horizontally arranged inside the hoist body 2. The fixed end of the steel wire rope 4 is connected to the rotating shaft 17. As the rotating shaft 17 rotates, the steel wire rope 4 is curled and wound around the rotating shaft 17 or released. One end of the rotating shaft 17 extends out of the side end face of the hoist body 2 as a driving end. A self-lubricating gear set 3 is arranged at the driving end. The gears in the self-lubricating gear set 3 mesh with each other and one of the gears is connected to a thread conversion shaft 6. The thread conversion shaft 6 can be driven by different lithium battery tools at the construction site, so as to lift objects and reduce the overall cost.

[0028] The self-lubricating gear set 3 includes a connection hole 7, a wheel body 9 and a number of teeth 8 evenly distributed in a circle on the outer side surface of the wheel body. An oil storage cavity 10 is arranged inside the wheel body 9. A number of oil outlet holes 14 and an oil injection hole 12 are arranged outside the wheel body 9. A groove 11 is arranged at the place where the oil injection hole 12 is flush with the outer side surface of the wheel body 9. Both the oil outlet holes 14 and the oil injection hole 12 are connected to the oil storage cavity 10. A plug 13 is arranged at the oil injection hole 12. The plug 13 includes a cap 1301 and a cover body 1302. The middle part of the cover body 1302 fits with the oil injection hole 12. The diameters of the upper and lower parts of the cover body 13 are smaller than the middle part. The cap 1301 abuts against the inner wall of the groove 11. A pressing mechanism 15 is arranged inside the oil outlet hole 14. The pressing mechanism 15 includes a plug 1503, a housing 1501 and a spring 1502. One end of the spring 1502 is fixedly connected to the plug 1503. The other end of the spring 1502 is connected to the housing 1501. The housing 1501 is arranged on the inner wall of the oil outlet hole 14. The end of the plug 1503 is adapted to the end of the housing 1501. A number of oil inlet holes 16 are arranged at the bottom of the housing 1501. The plug 1503 protrudes from the outer side surface of the wheel body 9.

[0029] When specifically using this device, first inject lubricating oil into the oil storage cavity 10 through the oil injection hole 12, and then cover the plug 13. After the device starts running, the lubricating oil stored in the oil storage cavity 10 is led out by setting a pressing mechanism 15 in the oil outlet hole 14. When the self-lubricating gear set 3 rotates, the gears mesh with each other, and the teeth 8 of other gears will press the plug 1503, thereby opening the oil outlet hole 14. The lubricating oil in the oil storage cavity 10 enters the tooth surface of the teeth 8 through the oil outlet hole 14, ensuring the lubrication when the teeth 8 are in transmission with another gear or the thread conversion shaft 6, reducing the wear of the gears, and thus extending the service life of the self-lubricating gear set 3. When the self-lubricating gear set 3 does not rotate, the plug 1503 is pressed against the end of the housing 1501 under the action of the spring 1502, preventing the oil from flowing out of the oil outlet hole 14 and sealing the oil storage cavity 10. This device transmits force to the gears through threads, and increases the speed ratio through the transmission of force, so that the object to be lifted can be easily lifted, thereby reducing the manual handling operation, saving labor, reducing the labor intensity of workers, and extending the service life of the hand chain hoist by setting the self-lubricating gear set 3, greatly saving costs.

[0030] Therefore, the present utility model adopts a hand chain hoist driven by a lithium battery tool with the above structure to solve the problems existing in the prior art, such as laborious operation, low efficiency, easy jamming of the lifting chain, high fatigue degree of the operator, and certain safety hazards. Moreover, it also prevents the teeth of the gears from wearing during continuous meshing, and extends the service life of the hand chain hoist.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present utility model, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present utility model.
