Description

Technical Field

[0001] The utility model relates to the technical field of brake motors, in particular to a winch reduction motor. Background Art

[0002] A Chinese patent with announcement number CN218771623U discloses a winch reduction motor with a ratchet brake, including a motor and a reducer assembly transmission-connected to the motor, wherein the reducer assembly is provided with a transmission-connected output gear and a main shaft, the output gear is transmission-connected to the output shaft of the motor, the output gear is provided with a synchronously rotating ratchet, a brake assembly is provided on the circumference of the ratchet, the brake assembly includes a fixed shaft, a compression spring and a pawl, the pawl is rotationally connected to the fixed shaft, and the compression spring pushes the pawl close to the ratchet.

[0003] The above-mentioned reduction motor is provided with a synchronously rotating ratchet on the output gear, and a brake assembly is provided on the periphery of the ratchet, and the brake assembly includes a compression spring and a pawl. When the motor is operating normally, the ratchet rotates normally. When the motor stops working, the load drives the main shaft to rotate in the opposite direction, and the ratchet on the output gear rotates in the opposite direction with the main shaft. At this time, the teeth on the pawl and the ratchet wheel press against each other, limiting the reverse rotation of the ratchet wheel, thereby achieving a braking effect.

[0004] However, in actual use, there are still some defects. For example, when the rope on the winch needs to be released, when the rope is pulled, the winch will be reversed. Because the winch is connected to the main shaft, the main shaft will reverse with the winch, but the ratchet on the output gear will also rotate in the opposite direction with the main shaft, but the reversed ratchet will be blocked by the pawl, resulting in the rope cannot be released from the winch normally.

[0005] Therefore, a winch reduction motor is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a winch reduction motor, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0007] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

[0008] A winch reduction motor comprises a motor and a reduction gear housing, wherein the reduction gear housing is fixedly mounted on one end of the motor by bolts, and a first gear is fixedly mounted on the rotating shaft of the motor after the rotating shaft rotates and extends into the interior of the reduction gear housing, a rotating shaft is rotatably mounted inside the reduction gear housing, a second gear is fixedly connected to one end of the rotating shaft close to the motor, and a third gear is fixedly connected to the other end of the rotating shaft, a main shaft is rotatably mounted on the side of the reduction gear housing away from the motor, a fourth gear is fixedly mounted on one end of the main shaft, and the other end of the main shaft is fixedly connected to the rotating shaft of the capstan, a rope is wound around the capstan, the fourth gear is meshed with the third gear, the second gear is meshed with the first gear, a ratchet is fixedly sleeved on the rotating shaft, a ratchet pawl is arranged in the reduction gear housing, which can prevent the rotating shaft of the motor from rotating counterclockwise when the rope pulls the load, the ratchet pawl can be stuck in the tooth groove of the ratchet, and a conversion mechanism is arranged in the reduction gear housing, which can push the ratchet pawl out of the tooth groove of the ratchet when the rope is released.

[0010] In the winch reduction motor according to the utility model, the conversion mechanism includes a conversion member, which is slidably arranged inside the reducer housing, the conversion member is L-shaped, a pushing head is arranged at one end of the conversion member, and a driving mechanism is arranged inside the reducer housing to drive the pushing head to push the pawl in a direction away from the ratchet.

[0011] In the winch reduction motor according to the utility model, the driving mechanism includes a mounting seat, the mounting seat is fixedly mounted inside the reducer housing, an electromagnet is fixedly mounted on the mounting seat, and an iron block is fixedly embedded at one end of the pushing head close to the pushing head.

[0012] In the winch reduction motor according to the utility model, a mounting plate is fixedly installed inside the reducer housing, a sliding sleeve is fixedly installed on the top of the mounting plate, a concave cutout is opened on one side of the conversion member, a guide rod is fixedly connected inside the concave cutout, and the sliding sleeve is slidably mounted on the guide rod.

[0014] The utility model has at least the following beneficial effects:

[0015] The utility model can energize the electromagnet through the conversion mechanism when it is necessary to release the rope on the winch, so that the magnetic force is adsorbed on the iron block on the conversion member, so that the push head moves in the direction of the pawl, and the upper end of the pawl is pushed out from the tooth groove of the ratchet wheel through the push head. At this time, the pawl releases the restriction on the reverse rotation of the ratchet wheel, and then the rope on the winch can be released by controlling the rotating shaft of the motor to rotate counterclockwise;

[0016] When the load is pulled by the rope, the electromagnet is first powered off. At this time, the electromagnet releases the adsorption of the conversion part, and under the elastic force of the spring, the pushing head is pushed away from the pawl, thereby releasing the squeezing of the pawl, and then under the elastic force of the elastic sheet, the upper end of the pawl is pressed against the ratchet again. After the load is pulled into place, when the motor stops, the load on the rope drives the main shaft to reverse, and then drives the rotating shaft to reverse through the third gear and the fourth gear, and then drives the ratchet to reverse. At this time, the upper end of the pawl can be stuck in the tooth groove of the ratchet under the elastic force of the elastic sheet, effectively preventing the ratchet from reversing, and then locking the position of the load.

In this embodiment, the conversion mechanism includes a conversion member 6, and the conversion member 6 is slidably arranged in the reducer housing 2, wherein a mounting plate 605 is fixedly installed in the reducer housing 2, a sliding sleeve 604 is fixedly installed on the top of the mounting plate 605, and a concave cutout is provided on one side of the conversion member 6 602, a guide rod 603 is fixedly connected to the inside of the concave cutout 602, a sleeve 604 is slidably sleeved on the guide rod 603, the conversion member 6 is L-shaped, a push head 601 is arranged at one end of the conversion member 6, a driving mechanism for driving the push head 601 to push the pawl 501 away from the ratchet 5 is arranged inside the reducer housing 2, the driving mechanism includes a mounting seat 7, the mounting seat 7 is fixedly mounted inside the reducer housing 2, an electromagnet 8 is fixedly mounted on the mounting seat 7, and an iron block is fixedly embedded at one end of the push head 601 close to the push head 601.

[0026] Working principle: When the rope on the winch needs to be released, the electromagnet 8 is energized, and the magnetic force is used to adsorb the iron block on the conversion member 6, so that the push head 601 moves in the direction of the pawl 501, and the upper end of the pawl 501 is pushed out from the tooth groove of the ratchet 5 by the push head 601.
