Description

Technical Field

[0001] This invention belongs to the field of winch technology, and particularly relates to a winch driven by dual servo motors. Background Technology

[0002] A winch is a construction equipment widely used in the fields of power, communications, and construction. It is mainly used for the traction, laying, and tension control of materials such as cables, optical cables, and wires. It is mainly driven by a power unit to drive the transmission mechanism, which in turn drives the winch or hoist to rotate and generate linear traction force.

[0003] Existing winches typically use a servo motor to drive the wire rope to wind up, thereby pulling cables or heavy objects. However, because winches often lack a tension control mechanism, problems such as cable breakage, twisting, or slack caused by excessive or insufficient tension cannot be effectively avoided during operation, affecting the quality and safety of traction. Summary of the Invention

[0004] The present invention addresses the problems existing in the prior art. Specifically, the technical problem to be solved by the present invention is to provide a winch driven by dual servo motors. The winch is reasonably designed and can easily control and adjust the tension on the wire rope of the winch roller, so as to avoid the wire rope from becoming loose or broken due to insufficient or excessive tension, thereby improving its traction quality and safety.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a winch driven by dual servo motors, comprising a base, a winch roller, a first servo motor, a second servo motor, and a tension control mechanism. The winch roller is horizontally arranged above the base. The first servo motor and the second servo motor are distributed on the left and right sides of the winch roller and installed on the top of the base. The output shafts of the first servo motor and the second servo motor are respectively connected to the left and right ends of the winch roller. The tension control mechanism includes a tension detector located in front of the winch roller to facilitate the passage of a steel wire rope. The tension detector is driven to rise and fall by a lifting adjustment component to adjust the tension of the winch roller tension.

[0006] Furthermore, the lifting adjustment component includes a lifting connecting frame that slides vertically with the front end of the base, and a vertically arranged lead screw is screwed to the rear end of the lifting connecting frame. The lead screw is rotatably mounted on the base; the tension detector is mounted at the front end of the lifting connecting frame.

[0007] Furthermore, the tension detector is equipped with three tension adjustment wheels.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0021] like Figures 1-4 As shown, this invention discloses a winch driven by dual servo motors, aiming to overcome the shortcomings of existing winches, which often lack a precise tension control mechanism during use. This leads to problems such as cable breakage, twisting, or slack caused by excessive or insufficient tension during operation, affecting the quality and safety of traction. Specifically, it includes a base 1, a winch roller 6, a first servo motor 3, a second servo motor 4, and a tension control mechanism 7. The winch roller 6 is horizontally positioned above the center of the base 1. The first servo motor 3 and the second servo motor 4 are distributed on the left and right sides of the winch roller 6, respectively. The first servo motor 3 and the second servo motor 4 are installed at the top left and right ends of the base 1. The output shafts of the first servo motor 3 and the second servo motor 4 are connected to the roller shafts at the left and right ends of the winch roller 6, respectively. The first servo motor 3 and the second servo motor 4 drive the winch roller 6 to rotate. The tension control mechanism 7 includes a tension detector 72 located in front of the winch roller 6 to facilitate the passage of the wire rope. The tension detector 72 is driven to rise and fall by a lifting adjustment component to adjust the tension of the winch roller cable. The winch roller is driven by dual servo motors. By adjusting the dual motors, the output torque and speed can be precisely controlled, providing a more stable traction quality. The tension detector is driven to rise and fall by the lifting adjustment component, which facilitates the control and adjustment of the wire rope tension.

[0022] In this embodiment, a vertical groove 9 is provided in the middle of the front end face of the base 1. The lifting adjustment component includes a lifting connecting frame 71, the rear end of which is slidably engaged with the vertical groove 9 in the middle of the front end face of the base 1. A vertically arranged lead screw 73 is screwed to the rear end of the lifting connecting frame 71, and the lead screw 73 is rotatably mounted on the base 1. The tension detector 72 is installed at the front end of the lifting connecting frame 71. During operation, the tension detector 72 monitors the tension on the wire rope. When the tension of the wire rope needs to be adjusted, the lead screw 73 is rotated, and the lifting connecting frame 71 moves vertically under the action of the thread, causing the tension detector 72 to move up and down. This allows the tension on the wire rope to be adjusted to a specified value, thus facilitating the control and adjustment of the tension on the wire rope of the winch roller 6.

[0023] In this embodiment, the tension detector 72 is rotatably equipped with three tension adjusting wheels 75. During operation, the wire rope passes between the three tension adjusting wheels 75 of the tension detector 72, allowing the tension detector 72 to monitor the tension on the wire rope. It should be noted that the tension detector is an existing mature product, also called a tension meter, tension sensor, etc., and is widely used in the tension detection of wire ropes and cables. Its specific structure and working principle will not be described in detail here.

[0024] In this embodiment, in order to facilitate the rotation of the lead screw, a rotating handle 74 is connected to the upper end of the lead screw 73. By rotating the handle 74, the lead screw 73 can be rotated.

[0025] In this embodiment, two support blocks 5 are provided on the top surface of the base 1, one on the left and one on the right. The support blocks 5 are vertically arranged, and the grinding roller 6 is rotatably connected between the two support blocks 5.

[0026] In this embodiment, connecting frames 2 are respectively provided at the left and right ends of the rear side of the base 1. In use, the base 1 is fixed by connecting the connecting frames 2 with ropes.

[0027] In this embodiment, during use: first, the base 1 is placed in the operating area of ​​the winch, and then the base 1 is fixed by the connecting frame 2 and ropes; then, the wire rope on the winch roller 6 is connected to the cable or heavy object to be pulled; then, the first servo motor 3 and the second servo motor 4 can be started according to the needs of use. By adjusting the dual motors, the output torque and speed can be precisely controlled, providing a more stable traction quality. After the first servo motor 3 and the second servo motor 4 are started, the winch roller 6 rotates on the support block 5, winding up the wire rope on the winch roller 6 and pulling the cable or heavy object. When pulling the heavy object with the wire rope, the wire rope passes between the three tension adjustment wheels 75 of the tension detector 72, allowing the tension detector 72 to detect the tension on the wire rope. When it is necessary to adjust the tension of the wire rope, the handle 74 is rotated, causing the lead screw 73 to rotate. Under the action of the thread, the lifting connecting frame 71 moves up and down, causing the tension detector 72 to move up and down synchronously. This allows the tension on the wire rope to be adjusted to a specified value, thus facilitating the control and adjustment of the tension on the wire rope of the winch roller 6, avoiding the wire rope from becoming loose or broken due to insufficient or excessive tension, and improving its traction quality and safety.

[0028] In this embodiment, as Figure 1 and Figure 4As shown, it also includes a protective mechanism 8 for limiting the reverse rotation of the winch roller 6. The protective mechanism 8 includes two ratchet wheels 81, two pawls 83, two support frames 82, and two telescopic springs 84. The ratchet wheels 81 are rotatably connected to the two support blocks 5 on opposite sides. The ratchet wheels 81 are coaxially connected to the winch roller 6 and are mounted on the roller shaft of the winch roller 6, rotating synchronously with the winch roller 6. Each ratchet wheel 81 has a support frame 82 fixed to the top of the base 1 on its front side. The upper end of the support frame 82 has a U-shaped hinge interface. The lower end of the pawl 83 is rotatably connected to the U-shaped hinge interface of the support frame 82. The pawl part of the pawl 83 is located at the upper end. A telescopic spring 84 is connected between the pawl 83 and the base 1. The telescopic spring is inclined with the front end higher and the rear end lower. The telescopic spring 84 pulls the pawl part of the pawl 83 to lock the ratchet wheel 81 by tension. It should be noted that, under normal conditions, the telescopic spring is in a stretched state so that the pawl of the pawl 83 can firmly lock the ratchet 81.

[0029] In this embodiment, the pawl 8 is L-shaped, which facilitates locking and restricting the ratchet 81.

[0030] By setting up this protective mechanism, the reverse rotation of the winch roller 6 can be prevented. When the first servo motor 3 and the second servo motor 4 are started to pull the heavy object, the winch roller 6 rotates, which drives the ratchet 81 to rotate in the forward direction. Under the tension of the extension spring 84, the pawl 83 rotates and resets intermittently, which does not affect the forward rotation of the ratchet 81. When the ratchet 81 rotates in the reverse direction, the pawl 83 locks and restricts the ratchet 81 to prevent it from rotating in the opposite direction. This can prevent the winch roller 6 from rotating in the reverse direction, prevent damage to the winch roller 6, and improve the service life of the winch roller 6.

[0031] The advantages of this invention are:

[0032] (1) By rotating the handle, the screw rotates, and the lifting connecting frame moves under the action of the screw thread, which in turn moves the tension detector. This allows the tension on the wire rope to be adjusted to the specified size, thus enabling easy control and adjustment of the tension on the wire rope of the winch roller, avoiding the wire rope from becoming loose or broken due to insufficient or excessive tension, and improving its traction quality and safety.

[0033] (2) The rotation of the grinding roller drives the ratchet to rotate in the forward direction. Under the action of the extension spring, the pawl rotates and resets intermittently, which does not affect the forward rotation of the ratchet. When the ratchet rotates in the reverse direction, the pawl locks and restricts the ratchet to prevent the ratchet from rotating in the reverse direction. This achieves the effect of preventing the grinding roller from rotating in the reverse direction, preventing damage to the grinding roller, and improving the service life of the grinding roller.

[0034] If this invention discloses or relates to components or structural parts that are fixedly connected to each other, then, unless otherwise stated, a fixed connection can be understood as: a fixed connection that can be detached (e.g., using bolts or screws), or a fixed connection that cannot be detached (e.g., riveting, welding). Of course, a fixed connection can also be replaced by an integral structure (e.g., manufactured in one piece using a casting process) (except where it is obviously impossible to use an integral molding process).
