[0023] The above and other technical features and advantages of the utility model are further described below in conjunction with the accompanying drawings and embodiments. However, the following embodiments are only preferred embodiments of the utility model, not all of them. Example

[0024] like Figure 1-4 As shown, the utility model provides a winch for cable retracting, comprising a winch stand 1, a cable retracting roller 2 for retracting and releasing cables is arranged at the inner upper end of the winch stand 1, a transmission rod 3 is arranged at the inner upper end of the winch stand 1, a transmission gear set 4 for driving the cable retracting roller 2 to rotate is arranged on one side of the transmission rod 3, a hand-cranked power rod 5 for driving the transmission gear set 4 is arranged on one side of the winch stand 1, a connecting sleeve rod 6 for auxiliary connection is arranged between the hand-cranked power rod 5 and the transmission rod 3, and a deceleration check assembly 7 for limiting the reverse rotation of the transmission rod 3 is arranged on the other side of the transmission rod 3;

[0025] The hand-cranked power rod 5 drives the transmission gear set 4 to rotate through the transmission rod 3, and the cable retracting roller 2 connected to the transmission gear set 4 is driven by the transmission gear set 4 to rotate synchronously, and the rotating cable retracting roller 2 completes the retraction and release of the cable.

[0026] The transmission rod 3 includes a first transmission rod 31, a second transmission rod 32, and a third transmission rod 33. The first transmission rod 31, the second transmission rod 32, and the third transmission rod 33 are installed at the upper end of the winch frame 1 in a herringbone arrangement. The first transmission rod 31, the second transmission rod 32, and the third transmission rod 33 are rotatably connected to the winch frame 1 through bearings. One end of the connecting sleeve rod 6 is fixedly connected to the first transmission rod 31, and the other end of the connecting sleeve rod 6 is sleeved on the outside of the end of the third transmission rod 33. The end of the third transmission rod 33 is provided with a hexagonal notch for connection.

[0027] The transmission gear set 4 includes a first transmission gear 41, a second transmission gear 42, a third transmission gear 43 and a fourth transmission gear 44;

[0028] The first transmission gear 41 is installed on one side of the cable retracting roller 2, the second transmission gear 42 is installed on one side of the third transmission rod 33, the third transmission gear 43 is installed on the end of the second transmission rod 32, and the third transmission gear 43 is meshed with the first transmission gear 41, the fourth transmission gear 44 is installed on the middle of the second transmission rod 32, the fourth transmission gear 44 is meshed with the third transmission gear 43, the second transmission gear 42 drives the fourth transmission gear 44 to rotate, the third transmission gear 43 linked with the second transmission gear 42 drives the first transmission gear 41 to rotate, and the first transmission gear 41 The gear ratio among the second transmission gear 42, the third transmission gear 43 and the fourth transmission gear 44 is 10:1:1.5:3. Through the setting of the gear ratio, the first transmission gear 41 can be easily driven to rotate by the hand-cranked power rod 5. The cable retracting roller 2 connected to the first transmission gear 41 can easily control the release of the cable, and better cope with the release of large-rolled cables. A plurality of groups of openings for weight reduction are provided inside the first transmission gear 41. By reducing weight, the inertial rotation of the first transmission gear 41 is reduced, thereby facilitating the deceleration and acceleration of the first transmission gear 41.

[0029] The hand-cranked power rod 5 comprises a connecting seat 51, an active rod 52 and a handle 53;

[0030] The connecting seat 51 is installed at the upper end of the side wall of the winch stand 1, the active rod 52 is slidably installed inside the connecting seat 51, and the handle 53 is sleeved on one end of the active rod 52. The active rod 52 can move laterally inside the connecting seat 51, and the handle 53 is used to drive the active rod 52 to rotate and move laterally;

[0031] The total length of the active rod 52 is longer than the distance from the connecting sleeve rod 6 to the side wall of the winch gantry 1. When the active rod 52 moves horizontally inside the connecting seat 51, the end of the active rod 52 can completely enter the connecting sleeve rod 6. The end of the active rod 52 is provided with a protrusion that cooperates with the hexagonal notch at the end of the third transmission rod 33. The protrusion and the hexagonal notch constitute a nested linkage structure. When the active rod 52 moves horizontally into the connecting sleeve rod 6, it can be connected to the hexagonal notch of the third transmission rod 33 through the protrusion. At this time, the rotation of the active rod 52 can synchronously drive the third transmission rod 33 to rotate, and through the cooperation of the transmission rod 3 and the transmission gear set 4, the cable retracting roller 2 is driven to rotate.

[0032] The deceleration check assembly 7 comprises a limiting rod 71, a ratchet wheel 72, a deceleration friction plate 73 and a deceleration friction rod 74;

[0033] The limiting rod 71 is sleeved on the end of the first transmission rod 31, and the ratchet 72 is sleeved on the other end of the second transmission rod 32 and meshes with the limiting rod 71. Under the restriction of the ratchet 72, the limiting rod 71 can rotate forward but cannot rotate reversely, thereby ensuring the continuity of the cable when it is released, and preventing the cable retracting roller 2 from rotating reversely due to the influence of the cable, thereby preventing the cable from being entangled.

[0034] The deceleration friction plate 73 is arranged on the side wall surface of the ratchet 72, and the deceleration friction rod 74 is arranged between the second transmission rod 32 and the active rod 52. The deceleration friction rod 74 is fixedly connected to the active rod 52, and the deceleration friction rod 74 is sleeved and connected to the second transmission rod 32. When deceleration is required, the deceleration friction rod 74 is driven to move laterally by pulling the active rod 52, and the other end of the deceleration friction rod 74 moves laterally along the surface of the second transmission rod 32 until it contacts the surface of the deceleration friction plate 73, and deceleration friction is achieved by means of resistance, thereby slowing down the cable release speed.

[0035] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
