Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic winches, in particular to a vehicle hydraulic winch driving mechanism. Background Art

[0002] Hydraulic winches can be divided into five types according to their usage methods: manual winch, electric winch, pneumatic winch, mechanical winch, and hydraulic winch. Vehicle hydraulic winches are mainly driven by a hydraulic system. Hydraulic winches use the hydraulic system to convert hydraulic energy into mechanical energy to work. Specifically, the hydraulic pump provides pressure to drive the hydraulic motor to rotate, and then drive the winch drum to rotate, realizing the traction and dragging of objects.

[0003] The existing vehicle-mounted hydraulic winch drive mechanism has a disadvantage: it uses an ordinary motor to drive the hydraulic pump. The motor's output speed is directly transmitted to the hydraulic pump, which then drives the hydraulic motor through hydraulic oil. This transmission process consumes some power, resulting in a relatively low power to drive the winch. To address this issue, we propose a vehicle-mounted hydraulic winch drive mechanism. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the deficiencies in the prior art, the utility model provides a vehicle-use hydraulic winch drive mechanism, which solves the problems raised in the background art.

[0006] (2) Technical solution

[0007] The utility model provides the following technical solutions: a vehicle hydraulic winch drive mechanism, comprising a protective box, a brake assembly, a drive motor and a circular box;

[0008] The driving motor is installed inside the protective box through a mounting bracket, and the circular box is fixed to the output shaft on one side of the driving motor through a flange. A sleeve is welded on the inner side of the protective box away from the driving motor, and a connecting shaft is sleeved inside the sleeve through a bearing. One end of the connecting shaft located inside the circular box is fixed with a first gear through a flat key, and a transmission gear is equidistantly arranged between the first gear and the circular box. The brake assembly includes a cylinder fixed to the top of the protective box by bolts, an iron sleeve is fixed inside the cylinder, and an electromagnetic coil is sleeved on the outer side of the iron sleeve located on the inner side of the cylinder, a compression spring is fixed to the top of the iron sleeve by bolts, and an iron rod is sleeved at the bottom end of the iron sleeve.

[0009] Furthermore, gear teeth are equidistantly arranged on the inner side of the circular box, and the gear teeth and the first gear are meshed with the transmission gear.

[0010] Furthermore, the top end of the iron rod located inside the iron sleeve is fixed to a limit block by bolts, and the bottom end of the compression spring is fixed to the top end of the limit block by bolts.

[0011] Furthermore, an arc-shaped plate is fixed to one end of the bottom end of the iron rod located inside the protective box by means of bolts, and clamping strips are welded to the bottom of the arc-shaped plate at equal intervals.

[0012] Furthermore, a braking gear is provided on the outer side of the connecting shaft located between the circular box and the sleeve via a flat key fixing sleeve.

[0013] Furthermore, a flange ring is fixedly sleeved on one end of the outer side of the protective box, and the cylinder is made of glass fiber material.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When the driving motor is powered on, it drives the circular box to rotate. The rotation of the circular box drives the transmission gear to rotate through the multiple gear teeth inside the circular box. The rotation of the transmission gear drives the first gear and the connecting shaft to rotate. The transmission of the gear teeth, the transmission gear and the first gear can effectively increase the speed of the connecting shaft.

[0016] When the drive motor is powered on, the electromagnetic coil is also powered on. After the electromagnetic coil is powered on, magnetism is generated in the iron sleeve, which attracts the iron rod inside, causing the arc plate to move away from the brake gear. After the drive motor and the electromagnetic coil are powered off, the compression spring pushes the iron rod downward through the limit block, causing the arc plate to press on the brake gear, and multiple clamping strips are engaged with the brake gear, thereby braking the connecting shaft through the brake gear.

[0017] The vehicle hydraulic winch drive mechanism is driven by a driving motor to drive the connecting shaft to rotate through the gear teeth, gear teeth and the first gear. Through the transmission of the gear teeth, transmission gear and the first gear, the speed of the connecting shaft can be effectively increased, thereby increasing the speed transmitted to the hydraulic pump body.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 5 , In the embodiment of the utility model, it includes a protective box 1, a brake assembly 2, a drive motor 3 and a circular box 4;

[0026] The driving motor 3 is installed inside the protective box 1 through a mounting bracket, and the circular box 4 is fixed to the output shaft on one side of the driving motor 3 through a flange. A sleeve 5 is welded on the inner side of the protective box 1 away from the driving motor 3, and a connecting shaft 6 is sleeved inside the sleeve 5 through a bearing. The connecting shaft 6 is located inside the circular box 4 and is fixed with a first gear 8 through a flat key at one end. A transmission gear 9 is equidistantly arranged between the first gear 8 and the circular box 4. The brake assembly 2 includes a cylinder 201 fixed to the top of the protective box 1 by bolts, and an iron sleeve 202 is fixed inside the cylinder 201. The outer side of the iron sleeve 202 located on the inner side of the cylinder 201 is sleeved with an electromagnetic coil 205, and a compression spring 206 is fixed to the top of the iron sleeve 202 by bolts, and an iron rod 204 is sleeved at the bottom end of the iron sleeve 202.

[0027] Among them, gear teeth 10 are equidistantly arranged on the inner side of the circular box 4. The gear teeth 10 and the first gear 8 are both engaged with the transmission gear 9. The rotation of the circular box 4 drives the transmission gear 9 to rotate through the gear teeth 10, and the transmission gear 9 then drives the first gear 8 to rotate.

[0028] Among them, the top of the iron rod 204 located inside the iron sleeve 202 is fixed to the limit block 203 by bolts, and the bottom of the compression spring 206 is fixed to the top of the limit block 203 by bolts. The setting of the limit block 203 can prevent the iron rod 204 from falling off from the iron sleeve 202.

[0029] Among them, the bottom end of the iron rod 204 located inside the protective box 1 is fixed with an arc plate 207 by bolts, and the bottom of the arc plate 207 is equidistantly welded with a clamping strip 208. The iron rod 204 moves downward to brake the brake gear 7 through the arc plate 207 and the clamping strip 208 at its bottom.

[0030] Among them, the connecting shaft 6 is located between the circular box 4 and the sheath 5 and is provided with a brake gear 7 on the outside through a flat key fixing sleeve. The setting of the brake gear 7 makes it easy for personnel to brake the connecting shaft 6.

[0031] Among them, a flange ring 11 is fixed on one end of the outer side of the protective box 1, and the cylinder 201 is made of glass fiber material. The protective box 1 can be installed and fixed using bolts through the flange ring 11. The cylinder 201 made of glass fiber material has high strength and good insulation ability, which can prevent the current on the electromagnetic coil 205 from being transmitted to the cylinder 201.

[0032] The working principle of the utility model is as follows: personnel use a flat key to insert one end of the connecting shaft 6 into the hydraulic body, and use bolts to fix the protective box 1 on the vehicle hydraulic winch through the flange ring 11. When the driving motor 3 is powered on, it drives the circular box 4 to rotate. The circular box 4 rotates through the multiple gear teeth 10 inside it to drive the transmission gear 9 to rotate. The transmission gear 9 rotates to drive the first gear 8 and the connecting shaft 6 to rotate. Through the transmission of the gear teeth 10, the transmission gear 9 and the first gear 8, the speed of the connecting shaft 6 can be effectively increased. When the motor 3 is powered on, the electromagnetic coil 205 is energized at the same time. After the electromagnetic coil 205 is energized, magnetism is generated in the iron sleeve 202, which adsorbs the iron rod 204 into it, causing the arc plate 207 to separate from the brake gear 7. After the driving motor 3 and the electromagnetic coil 205 are powered off, the compression spring 206 pushes the iron rod 204 downward through the limit block 203, causing the arc plate 207 to press on the brake gear 7, and multiple clips 208 are engaged with the brake gear 7, thereby braking the connecting shaft 6 through the brake gear 7.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
