Description

Technical Field

[0001] This utility model relates to the field of hydraulic winch technology, and more specifically to a hydraulic winch with a pneumatic clutch function. Background Technology

[0002] In many industrial sectors and special operation scenarios today, hydraulic winches play an indispensable role as an important traction and lifting device. They are widely used in material hoisting at construction sites, equipment relocation in mining operations, cargo loading and unloading at ports and docks, heavy object towing at fire and rescue sites, and supporting operations for various engineering vehicles.

[0003] As shown in the prior art published in CN208471425U, although the prior art uses a hydraulic brake to solve the defects of mechanical brakes such as high noise and one-way braking, and uses a pneumatic clutch to replace manual operation to solve the problem of ease of winch operation, this prior art can only position the gears in one direction. Therefore, if the clutch pin is damaged, the hydraulic winch will become loose. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a hydraulic winch with a pneumatic clutch function. The cylinder drives multiple racks on the adjustment plate to reciprocate, thereby facilitating the adjustment of the engagement between the racks and gears and enabling clutch adjustment according to the needs of the winch's use. Furthermore, the multiple racks allow for multi-directional limiting, thereby improving the limiting strength of the winch and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic winch with pneumatic clutch function, comprising a base, a fixed bracket installed on the top of the base, and a winch movably connected via a rotating shaft installed inside the fixed bracket, and a limiting member for positioning the winch provided outside the fixed bracket; The limiting component includes a mounting cylinder detachably connected to one side of the fixed bracket. Inside the mounting cylinder is a linkage shaft for connecting to the rotating shaft on the winch, and a gear is mounted on the outside of the linkage shaft. An adjusting plate is provided on the side of the gear near the mounting cylinder, and a rack extending to the outside of the gear is mounted on the side of the adjusting plate near the gear. A cylinder for driving the adjusting plate is mounted on the side of the mounting cylinder away from the fixed bracket. The cylinder drives multiple racks on the adjusting plate to reciprocate, thereby facilitating the engagement of the racks and gears and enabling clutch adjustment according to the needs of the winch. The multiple racks allow for multi-directional limiting, thereby improving the limiting strength of the winch.

[0006] In a preferred embodiment, a plurality of spaced positioning strips are installed on the outside of the mounting cylinder, and a positioning hole is provided on one side of the adjusting plate corresponding to the positioning strip. The positioning strip is located inside the positioning hole. By engaging the positioning strip with the positioning hole, the adjusting plate can be guided and limited, ensuring the stability of the adjusting plate during displacement and preventing the adjusting plate from shifting during the displacement process.

[0007] In a preferred embodiment, an installation ring is fitted around one end of the mounting cylinder near the fixed bracket, and multiple fastening bolts for connecting the fixed bracket are installed on the outside of the installation ring. By connecting the fastening bolts to the fixed bracket with threads, the mounting cylinder can be installed on the outside of the fixed bracket, thereby ensuring the stability of the mounting cylinder and improving the convenience of assembling and disassembling the mounting cylinder.

[0008] In a preferred embodiment, an oil pipe is fixedly connected to the top of one end of the mounting cylinder near the gear, and a sealing plug is detachably connected to the top of the oil pipe. The oil pipe facilitates the delivery of lubricating oil to the outside of the gear, thereby reducing wear between the gear and the rack and ensuring the performance of the gear and rack.

[0009] In a preferred embodiment, a sponge is provided inside the bottom end of the oil pipe, and multiple spaced brush strips are installed at the bottom end of the sponge. The bottom end of the brush strips contacts the top of the gear. By setting the sponge, lubricating oil can be stored inside the sponge, and by the pressure of the gear on the sponge, the lubricating oil can gradually adhere to the outside of the gear.

[0010] In a preferred embodiment, a servo motor for driving the winch is installed on the side of the fixed bracket away from the mounting cylinder. The servo motor output shaft is connected to the winch, so that the servo motor can drive the winch to operate, thereby improving the operating efficiency of the winch.

[0011] The technical effects and advantages of this utility model are as follows: 1. The cylinder drives multiple racks on the adjustment plate to move back and forth, which facilitates the adjustment of the engagement between the racks and gears, and enables clutch adjustment according to the needs of the winch. The multiple racks can be used for multi-directional limiting, thereby improving the limiting strength of the winch. 2. Lubricating oil is delivered to the outside of the gear through an oil pipe, thereby reducing friction between the gear and rack and reducing wear on the rack and gear. Then, through the reciprocating contact between the sponge and the gear, the lubricating oil in the sponge is squeezed to the outside of the gear, thereby lubricating the gear and rack and ensuring the performance of the gear and rack.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Refer to the instruction manual appendix Figure 1-5 This utility model provides a hydraulic winch with pneumatic clutch function, including a base 1, a fixed bracket 2 installed on the top of the base 1, and a winch 3 movably connected to the fixed bracket 2 via a rotating shaft, and a limiting member for positioning the winch 3 is provided on the outside of the fixed bracket 2; the limiting member includes a mounting cylinder 4 detachably connected to one side of the fixed bracket 2, a linkage shaft 5 for connecting the rotating shaft on the winch 3 is provided inside the mounting cylinder 4, and a gear 6 is installed on the outside of the linkage shaft 5, an adjusting plate 7 is provided on the side of the gear 6 near the mounting cylinder 4, and a rack 8 extending to the outside of the gear 6 is installed on the side of the adjusting plate 7 near the gear 6, and a cylinder 9 for driving the adjusting plate 7 is installed on the side of the mounting cylinder 4 away from the fixed bracket 2.

[0016] When using the winch 3 to wind up the hinge, it is necessary to separate the rack 8 on the operating plate 7 from the gear 6. Therefore, the cylinder 9 drives the adjusting plate 7 to move outward, and the rack 8 on the adjusting plate 7 separates from the gear 6. This makes the gear 6 unrestricted, which facilitates the winch 3 to wind up and rotate the hinge.

[0017] After the winch 3 is no longer restricted, it needs to be driven to operate. Therefore, a servo motor 18 for driving the winch 3 is installed on the side of the fixed bracket 2 away from the mounting cylinder 4. In this way, the winch 3 can be driven to operate by the servo motor 18, and the hinge can be wound up by the rotation of the winch 3, thereby realizing the winding up of the hinge.

[0018] After the winch 3 finishes winding the hinge, it needs to be limited. Therefore, the cylinder 9 needs to be operated to drive the rack 8 on the adjusting plate 7 to move inward. In this way, the rack 8 and the gear 6 can be engaged to limit the winch 3 and prevent the winch 3 from rotating. The setting of multiple racks 8 can limit the winch 3 from multiple directions, thus ensuring the limiting strength of the winch 3.

[0019] To ensure the stability of the adjusting plate 7 during displacement, it is necessary to limit its movement. Therefore, multiple spaced positioning strips 10 are installed on the outside of the mounting cylinder 4, and positioning holes 11 are provided on the side of the adjusting plate 7 corresponding to the positioning strips 10. The positioning strips 10 are located inside the positioning holes 11. In this way, the positioning strips 10 can be engaged with the positioning holes 11 to limit the movement of the adjusting plate 7, ensuring its stability during displacement and preventing it from tilting during the displacement process.

[0020] Furthermore, an oil pipe 14 is fixedly connected to the top of the mounting cylinder 4 near the gear 6. A sealing plug 15 is detachably connected to the top of the oil pipe 14, and a sponge 16 is provided inside the bottom end of the oil pipe 14. Multiple spaced brush strips 17 are installed at the bottom end of the sponge 16, with the bottom ends of the brush strips 17 contacting the top of the gear 6. This allows the operator to open the sealing plug 15 and then deliver lubricating oil to the outside of the gear 6 through the oil pipe 14, thereby reducing the friction between the gear 6 and the rack 8, effectively reducing the wear of the rack 8 and the gear 6. The reciprocating contact between the sponge 16 and the gear 6 also forces the lubricating oil inside the sponge 16 to the outside of the gear 6, thus lubricating the gear 6 and ensuring the performance of the gear 6 and the rack 8.

[0021] Meanwhile, an installation ring 12 is fitted around the end of the mounting cylinder 4 near the fixed bracket 2, and multiple fastening bolts 13 for connecting the fixed bracket 2 are installed on the outside of the mounting ring 12. This allows the operator to remove the fastening bolts 13, thereby freeing the mounting ring 12 from being restricted in position, and thus achieving the effect of convenient disassembly of the mounting cylinder 4, improving the convenience of maintenance of the gear 6 and rack 8.

[0022] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
