The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0037] In order to accurately control the pulley movement at low cost, a follower device for a winch is proposed in this application. Figure 1 FIG. 2 is a front view of a follower device for a winch in an embodiment of the utility model, as shown in FIG. Figure 1 As shown, the follower device for the winch may include: a drive unit 1, a first sliding member 2, a first pulley support 5 and a first pulley 4 installed on the first pulley support 5, a gear 6, a first rack 3, a second rack 8, a second sliding member 9, and a second pulley support 11 and a second pulley 10 installed on the second pulley support 11.
[0038] Among them, the driving unit 1 may have a moving part, and the driving unit 1 can controllably drive the moving part to move a preset distance along a first preset direction. The preset distance can be determined according to specific needs. In a specific embodiment, the driving unit 1 may include a hydraulic cylinder with a linear position sensor. The hydraulic cylinder has a moving part, and the extension and contraction amount of the moving part of the hydraulic cylinder can be controlled by the linear position sensor. In the above manner, the moving part of the hydraulic cylinder can be moved to any preset distance along the first preset direction under the linear position sensor.
[0039] The first sliding member 2 can move along the first preset direction, and the first sliding member 2 is connected to the moving part. When the driving unit 1 drives the moving part to move along the first preset direction by a preset distance, the first sliding member 2 is also driven to move along the first preset direction by a preset distance.
[0040] In order to ensure that the first sliding member 2 moves along the first preset direction, Figure 2 FIG. 1 is a partial side view of a follower device for a winch in an embodiment of the utility model, as shown in FIG. Figure 2 As shown, the follower device for the winch may include: a slider track 12 extending along a first preset direction, and a first sliding member 2 is installed in cooperation with the slider track 12.
[0041] The first pulley support 5 is connected to the first sliding member 2 , and the first sliding member 2 can drive the first pulley support 5 to synchronously move a preset distance along a first preset direction, thereby controlling the reciprocating translation of the first pulley 4 .
[0042] The first rack 3 and the second rack 8 are respectively arranged on both sides of the gear 6 and mesh with the gear 6. The axis of the gear 6 can be perpendicular to the first preset direction, so as to ensure that the first rack 3 and the second rack 8 can move back and forth along the first preset direction. The first rack 3 is connected to the first sliding member 2, and the first sliding member 2 can drive the first rack 3 to move synchronously along the first preset direction by a preset distance. At the same time, the gear 6 rotates, and the gear 6 drives the second rack 8 to move synchronously along the first preset direction by a preset distance in the opposite direction of the movement of the first rack 3.
[0043] The second sliding member 9 can move along the first preset direction, and the second sliding member 9 is connected to the second rack 8. When the second rack 8 moves synchronously by a preset distance along the first preset direction in the opposite direction of the movement of the first rack 3, the second rack 8 drives the second sliding member 9 to also move synchronously by a preset distance along the first preset direction in the opposite direction of the movement of the first rack 3. The second pulley support 11 is connected to the second sliding member 9, so that the second sliding member 9 can drive the second pulley support 11 to also move synchronously by a preset distance along the first preset direction in the opposite direction of the movement of the first rack 3, thereby controlling the reciprocating translation of the second pulley 10.
[0044] In order to ensure that the second sliding member 9 moves along the first preset direction, the second sliding member 9 can be installed in cooperation with the slider rail 12 .
[0045] In order to ensure that the distance moved by the moving part along the first preset direction is exactly the same as the distance moved by the second pulley 10 on the second pulley support 11 and the first pulley 4 on the first pulley support 5, the first rack 3, the second rack 8 and the first preset direction are parallel.
[0046] The follower device for the winch may include a gear box 7. The gear 6 is installed in the gear box 7 via a rotating shaft, and the rotating shaft may be perpendicular to the first preset direction. The gear box 7 may limit the position of the gear 6 and ensure that the axis of the gear 6 is fixed and does not move.
[0047] In order to enable the first rack 3 to keep moving back and forth along the first preset direction and always maintain a meshing state with the gear 6, it is feasible that a first insertion port 71 and a second insertion port 72 are opened on the gear box 7, and the first rack 3 is inserted into the first insertion port 71 and the second insertion port 72. The first insertion port 71 and the second insertion port 72 can press against the side of the first rack 3 facing away from the gear 6 to keep the first rack 3 and the gear 6 in a meshing state.
[0048] Similarly, the gear box 7 may be provided with a third insertion port 73 and a fourth insertion port 74, and the second rack 8 may be inserted into the third insertion port 73 and the fourth insertion port 74. The third insertion port 73 and the fourth insertion port 74 may be able to press against the side of the second rack 8 facing away from the gear 6 to keep the second rack 8 and the gear 6 in a meshing state.
[0049] In the above embodiment, the straight line formed between the first insertion port 71 and the second insertion port 72 is parallel to the straight line formed between the third insertion port 73 and the fourth insertion port 74 .
[0050] When the winch drum is working, Figure 3 FIG. 1 is a schematic diagram of the cooperation between the follower device for the winch and the detection element in the embodiment of the utility model. Figure 3As shown, the winch retracts and releases the steel wire rope 15 by rotating the drum 14, and the steel wire rope 15 coming out of the drum 14 is wound around the first pulley 4 and the second pulley 10 in the follower device. The position of the steel wire rope 15 coming out of the drum 14 in the axial direction of the drum 14 can be controlled by adjusting the distance between the first pulley 4 and the second pulley 10, thereby preventing the angle between the steel wire rope 15 coming out of the drum 14 and the steel wire rope 15 on the drum 14 to be retracted and released from being too large. Once the angle is too large, not only will the steel wire rope 15 on the drum 14 and the steel wire rope 15 on the drum 14 to be retracted and released be worn, but also when the drum 14 rotates to retract the steel wire rope 15, the steel wire rope 15 may not be able to be wound around the drum 14 in order. Therefore, the control system of the winch detects the number of rotations of the drum 14 through the detection element 13 and determines the theoretical translation position of the pulley of the follower device. After determining the theoretical translation position, the linear position sensor of the drive unit 1 controls the extension and contraction amount of the hydraulic cylinder, and uses the moving part to push the first sliding member 2 located on the slider track 12 to translate, driving the first pulley support 5 and the first pulley 4 to translate to the theoretical position. The first rack 3 translates with the first sliding member 2, driving the gear 6 to rotate, and the second rack 8 rotates with the gear 6 to maintain the opposite synchronous movement with the first rack 3, driving the second sliding member 9, the second pulley support 11, and the second pulley 10 to translate in the opposite synchronous direction, so that the second pulley 10 also translates to the theoretical position. In the above manner, the first pulley 4 and the second pulley 10 can be controlled to translate back and forth, so that the angle between the wire rope 15 coming out of the drum 14 and the wire rope 15 to be retracted and released on the drum 14 is controlled within a smaller range.
[0051] The follower device for the winch in the present application can bring the following beneficial effects:
[0052] First, in a large winch, the follower device can reduce costs and accurately control the reciprocating translation of the first pulley 4 and the second pulley 10 to avoid damage to the wire rope 15; second, in a complex working environment, the follower device can be separated from the winch to independently realize the pulley movement, effectively improving the protection of the follower device used for the winch in dangerous situations.
