Description

Technical Field

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

[0002] A winch is a small and light lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects, also known as a winch. The existing Chinese patent with the authorization announcement number CN118387790B discloses a winch assembly, which belongs to the technical field of drilling rig accessories. It includes: a base, two support seats, an electric motor and a reduction gearbox are fixedly installed on the top of the base, the same rotating shaft is rotatably installed on the two support seats, a drum is fixedly sleeved on the rotating shaft, a wire rope is wound on the drum, the output end of the motor is connected to the input end of the reduction gearbox, and the output end of the reduction gearbox is connected to one end of the rotating shaft, the two retaining rings of the drum are fixedly sleeved with brake discs, and the outer walls of both sides of the two support seats are fixedly mounted with hydraulic oil brakes that match the brake discs, two first slide bars are installed on the base, and the sliding sleeves on the two first slide bars are provided with moving seats, and the top of the moving seat is provided with a first wheel frame. The winch assembly provided by the present invention has the advantages of being able to scrape off debris adhered to the wire rope during the process of pulling a heavy object, which is conducive to making the wire rope reeling more compact and regular, having a wide range of applicability and being easy to use.

[0003] However, in actual applications, the above-mentioned winch assembly still has the following deficiencies: when the above-mentioned winch is performing a winding operation, due to the lack of guidance of the wire rope, the wire rope on the drum is often only wound on one side, resulting in uneven winding of the wire rope on the drum. When the thickness of the wire rope winding on one side of the drum is too high, there may be a risk of the wire rope slipping. In addition, due to the messy winding of the wire rope, it will also affect the winding amount of the wire rope by the drum, and the practicality is poor. Utility Model Content

[0004] The purpose of the present utility model is to address the above-mentioned deficiencies and provide a winch that can guide the wire rope during the winding process so that it is evenly wound on the drum, avoiding the wire rope slipping caused by the excessive thickness of the wire rope winding on one side of the drum, and can also increase the winding amount of the wire rope by the drum, thereby improving practicality.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A winch, comprising a motor, a dual-output shaft reducer and a drum installed on the frame, wherein the drum is installed on the output shaft one of the dual-output shaft reducer, and is characterized in that: a support seat installed on the frame, a roller rotatably connected to the support seat, a reciprocating sleeve connected to the support seat slidably along the axial direction of the roller, a spring hook fixed on the reciprocating sleeve, one end of the roller connected to the output shaft two of the dual-output shaft reducer, an annular groove is provided on the outer side wall of the roller, a guide roller is slidably connected in the groove, and one end of the guide roller is fixed to the reciprocating sleeve.

[0007] Furthermore, two opposite ends of the chute respectively extend toward two ends of the roller with the axis of the roller as the center.

[0008] Furthermore, a limiting groove is provided on the support seat, and a guide rail is provided on the reciprocating sleeve facing the limiting groove.

[0009] Furthermore, the rotating roller is arranged parallel to the reel.

[0010] The beneficial effects of the utility model are:

[0011] In actual application, when in use, the end of the wire rope is first passed through the spring hook and then wound and fixed on the drum. The motor drives the drum to rotate and rewind through the output shaft 1 of the dual-output shaft reducer. At the same time, the motor drives the roller to rotate through the output shaft 2 of the dual-output shaft reducer. During the rotation of the roller, the guide roller slides along the slide groove, and the reciprocating sleeve drives the spring hook and the wire rope to reciprocate, so that the wire rope on the spring hook is evenly wound on the drum. The utility model can guide the wire rope during the winding process and make it evenly wound on the drum, avoiding the situation that the wire rope slips due to the excessive thickness of the wire rope winding on one side of the drum, and can also increase the winding amount of the wire rope by the drum, so it is more practical.

[0016] like Figure 1、 Figure 2 and Figure 3 As shown, a winch is installed on the frame 1, a motor 2, a dual-output shaft reducer 3 and a drum 4, and the drum 4 is installed on the output shaft 1 of the dual-output shaft reducer 3. It is characterized in that: a support seat 5 installed on the frame 1, a roller 6 rotatably connected to the support seat 5, a reciprocating sleeve 7 connected to the support seat 5 along the axial direction of the roller 6, a spring hook 8 fixed on the reciprocating sleeve 7, one end of the roller 6 is connected to the output shaft 2 of the dual-output shaft reducer 3, an annular slide groove 61 is provided on the outer side wall of the roller 6, a guide roller 9 is slidably connected in the slide groove 61, and one end of the guide roller 9 is fixed on the reciprocating sleeve 7.

[0017] When in use, the end of the wire rope is first passed through the spring hook 8 and then wound and fixed on the drum 4. The motor 2 drives the drum 4 to rotate and rewind through the output shaft 1 of the dual-output shaft reducer 3. At the same time, the motor 2 drives the roller 6 to rotate through the output shaft 2 of the dual-output shaft reducer 3. During the rotation of the roller 6, the guide roller 9 slides along the slide groove 61, and the reciprocating sleeve 7 drives the spring hook 8 and the wire rope to reciprocate, so that the wire rope on the spring hook 8 is evenly wound on the drum 4; the utility model can guide the wire rope during the winding process, so that it is evenly wound on the drum 4, avoids the wire rope slipping caused by the excessive thickness of the wire rope winding on one side of the drum 4, and can also increase the winding amount of the wire rope of the drum 4, so that it is more practical.

[0018] like Figure 1 、 Figure 2 and Figure 3 As shown, the two opposite ends of the slide groove 61 extend toward the two ends of the roller 6 respectively with the axis of the roller 6 as the center; in this embodiment, when the two opposite ends of the slide groove 61 extend toward the two ends of the roller 6 respectively with the axis of the roller 6 as the center, the reciprocating sleeve 7 can perform axial reciprocating motion along the roller 6.

[0019] like Figure 1 、 Figure 2 and Figure 3 As shown, a limiting groove 51 is provided on the support seat 5, and a guide rail 71 is provided on the reciprocating sleeve 7 opposite to the limiting groove 51; in this embodiment, the reciprocating sleeve 7 cooperates with the limiting groove 51 on the support seat 5 through the guide rail 71, thereby limiting the moving direction of the reciprocating sleeve 7 and ensuring that it does not deviate from the track when it moves left and right in the horizontal direction.

[0020] like Figure 1 、 Figure 2 and Figure 3 As shown, the roller 6 is arranged parallel to the reel 4; in this embodiment, when the roller 6 is arranged parallel to the reel 4, the wire rope on the spring hook 8 can be evenly wound onto the reel 4.
