Description

Technical Field

[0001] This utility model relates to the field of winch technology, specifically a winch with a traveling mechanism. Background Technology

[0002] A winch is a small, lightweight lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects. Winches can lift vertically and pull horizontally or at an angle. There are three types of winches: manual winches, electric winches, and hydraulic winches.

[0003] Existing winch bases are generally fixed to a foundation. For example, an electric winch disclosed in CN114920156A includes a housing, a reducer, a drum, and a wire rope. The drum is connected to the output end of the reducer via a shaft. An emergency brake pad is provided on the outside of the shaft. One end of the drum is connected to the shaft, and the other end of the drum is provided with a first sprocket. A support frame is provided on the housing, and a rope guide is provided on the support frame. The wire rope is limited within the guide component by a left-right sliding guide component on a bidirectional screw, which serves as a guide and easily achieves good linkage according to the rotation of the drum. It is simple and easy to implement.

[0004] The problem with the winch base being fixed to the foundation is that, since the winch is stationary, the position of the wire rope relative to the foundation changes when it is raised or lowered. This causes the wire rope to form an angle with the fixed pulley, resulting in increased wear on both the wire rope and the fixed pulley. Utility Model Content

[0005] The purpose of this invention is to provide a winch with a traveling mechanism to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a winch with a traveling mechanism, comprising a drum, a base, a drum support, and a mounting platform. The base reciprocates on the mounting platform. A fixed support is mounted in the middle of the mounting platform, and a lead screw cooperating with a lead screw nut is rotatably mounted on the fixed support. A driven sprocket is mounted at one end of the lead screw. A drum support is mounted at the top of the base, and a bearing seat is mounted on one side of the drum support. The drum is mounted on the bearing seat, and a driving sprocket is mounted at one end of the drum. The driving sprocket and the driven sprocket are connected by a chain. A motor is mounted on the other side of the drum support, and the motor drives the drum to rotate through a planetary gearbox.

[0007] Preferably, the mounting platform is provided with side supports on both sides of the base, a first steel rail is installed on one of the side supports of the mounting platform, a second steel rail is installed on the other side support, a wheel is installed on the base above the first steel rail, a wheel is installed on the base below the second steel rail, and a guide rail is installed on the mounting platform below the wheel below the second steel rail.

[0008] Preferably, the base is rotatably mounted with guide wheels that cooperate with the side bracket.

[0009] Preferably, the mounting platform is equipped with limit devices at both ends of the base's movement direction.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The base moves back and forth on the installation platform. A fixed support is installed in the middle of the installation platform. A screw that mates with a screw nut is rotatably installed on the fixed support. A driven sprocket is installed at one end of the screw. A drum bracket is installed at the top of the base. A bearing seat is installed on one side of the drum bracket. The drum is installed on the bearing seat. A drive sprocket is installed at one end of the drum. The drive sprocket and the driven sprocket are connected by a chain. When the winch is working, the drum part of the winch will move axially accordingly as the wire rope is wound and unwound on the drum, so that the relative position of the wire rope remains unchanged.

[0012] 2. Saves installation space: Since the axial movement of the drum keeps the relative position of the wire rope unchanged, there is no need to increase the distance between the winch and the fixed pulley to reduce the angle. The distance between the winch and the fixed pulley can be greatly reduced, which can save a lot of installation space for the equipment.

[0013] 3. Saves wire rope: A winch with a traveling mechanism can significantly reduce the distance between the winch and the fixed pulley. For the same lifting height, a shorter wire rope is required, thus saving wire rope costs.

[0014] 4. Extend the service life of wire rope: The absence of an angle between the wire rope and the drum / pulley results in less friction and wear on both sides of the wire rope, extending the service life of expensive wire ropes and thus saving maintenance costs. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0020] Please see Figure 1-2 In this embodiment of the present invention, a winch with a traveling mechanism includes a drum 1, a base, a drum support 7, and a mounting platform 13. The base reciprocates on the mounting platform 13. A fixed support 11 is mounted in the middle of the mounting platform 13. A lead screw 10, which cooperates with a lead screw nut 12, is rotatably mounted on the fixed support 11. A driven sprocket is mounted at one end of the lead screw 10. The drum support 7 is mounted at the top of the base. A bearing seat 4 is mounted on one side of the drum support 7. The drum 1 is mounted on the bearing seat 4. A drive sprocket 5 is mounted at one end of the drum 1. The drive sprocket 5 and the driven sprocket are connected... The drum 1 is connected by chain 6; a motor 2 is installed on the other side of the drum support 7, and the motor 2 drives the drum 1 to rotate through the planetary gearbox 3; the motor 2 drives the winch drum 1 to rotate forward and backward, the drum 1 winds up and unwinds the wire rope, and drives the hoisted load to move up and down; the drive sprocket 5, which is fixed to the tail of the drum 1 and rotates together, drives the chain 6 and the driven sprocket and screw 10 installed on the drum support 7 to rotate together. Since the screw nut 12 is fixed on the mounting platform 13 by the fixed support 11, the rotation of the screw causes the winch as a whole to move back and forth on the rail along the axial direction of the drum, thereby keeping the relative position of the wire rope unchanged.

[0021] The mounting platform 13 is provided with side supports 14 on both sides of the base. A first steel rail 15 is installed on one side support 14 of the mounting platform 13, and a second steel rail 17 is installed on the other side support 14. A wheel 9 is installed on the base above the first steel rail 15 and below the second steel rail 17.

Limiting devices 8 are installed at both ends of the mounting platform 13 in the direction of base movement.

[0022] The working principle of this utility model is as follows: the motor 2 drives the winch drum 1 to rotate in both directions, the drum 1 winds up and unwinds the wire rope, and drives the hoisted load to move up and down; the drive sprocket 5, which is fixed to the tail of the drum 1 and rotates together, drives the chain 6 and the driven sprocket and screw 10 installed on the drum bracket 7 to rotate together. Since the screw nut 12 is fixed to the mounting platform 13 by the fixed support 11, the rotation of the screw causes the winch as a whole to move back and forth on the rail along the axial direction of the drum, thereby keeping the relative position of the wire rope unchanged.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
