Description

Technical Field

[0001] The utility model relates to a special tool for winding a bridge crane hoisting wire rope around a reel, belonging to the technical field of hoisting equipment. Background Art

[0002] A bridge crane is a crane used for loading and unloading operations at a dock. It is the heart of the dock. The operating capacity of the bridge crane determines the cargo handling capacity of a dock.

[0003] The loading and unloading of containers by bridge cranes relies on the traction of the wire rope of the lifting mechanism. When the lifting device for grabbing the box tilts, the length of the four wire ropes at the four ends of the lifting device needs to be adjusted to maintain balance. There are more than a dozen turns of lifting wire rope wrapped around the lifting drum in the large machine room. The method to adjust the length of the wire rope is to loosen the wire rope tightly wound on the drum, and then tighten the loosened wire rope on the drum after adjusting the length. There is a rope groove for the wire rope on the drum. In the past, maintenance personnel used to hold the wire rope with their upper hands and turn it over back and forth in circles. Due to the space and the weight of the wire rope, there is a risk of squeezing the hands.

[0004] The invention patent with application number CN202310693194.7 discloses a lifting wire rope length adjustment device for a gantry crane, including a rope frame, a U-shaped guide frame connected to the front side of the inner wall of the rope frame, and a screw is installed inside the U-shaped guide frame through the output end of a servo motor. The lifting wire rope length adjustment device provided by the present invention can control the nut sleeve to move along the U-shaped guide frame through the driving action of the screw at the output end of the servo motor, that is, the slotted wheel can be used to cooperate with the wire rope for disk arrangement and recovery, and through the control action of the sealing plug of the automatic telescopic rod inside the control module, the slotted wheel and the wire rope on the inner wall can be squeezed and lubricated with the lubricating oil stored in the storage cylinder, which effectively solves the problem that the wire rope extension module of the lifting wire rope length adjustment device of the gantry crane provided by the present invention does not have the arrangement and recovery function, and the manual application of lubricating oil is time-consuming and labor-intensive, but it cannot be applied to the adjustment of the length of the bridge crane lifting wire rope.

[0019] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 The shown special tool for winding the wire rope of a bridge crane comprises a U-shaped tube 1, a gate-shaped rod 2 is arranged inside the U-shaped tube 1, the vertical rod of the gate-shaped rod 2 is located inside the vertical tube of the U-shaped tube 1, the cross rod of the gate-shaped rod 2 passes through the inner walls on both sides of the U-shaped tube 1, a handle 3 is fixedly arranged on the cross rod of the gate-shaped rod 2, a spring 5 is arranged on the lower end surface of the vertical rod of the gate-shaped rod 2, a wire hook 6 is arranged at the lower end of the spring 5, the wire hook 6 is fixedly connected to the inner wall of the U-shaped tube 1, a cross plate 8 is arranged directly below the cross rod of the gate-shaped rod 2 through a connecting rod 7, and a friction plate 9 is arranged on the lower end surface of the cross plate 8.

[0021] When using the utility model, first hold the U-shaped tube 1 and pull the handle 3 hard, so that the cross plate 8 drives the friction plate 9 to move upward, making room for hooking the wire rope 10 in the wire hook 6, and release the handle 3. The friction plate 9 is tightly pressed on the wire rope 10 by the downward pulling force of the spring 5. At this time, you can hold the U-shaped tube 1 tightly to overturn the wire rope 10, avoiding direct contact with the wire rope 10 with both hands, which plays a good protective role for both hands.

[0022] The outer side of the lower part of the U-shaped tube 1 extends to the same height as the wire hook 6, and the outer side of the lower part of the U-shaped tube 1 is bent inward.

[0023] Wherein, guide wheels 4 are installed outside the vertical rod of the gate-shaped rod 2. The gate-shaped rod 2 can move up and down more smoothly and stably.

[0024] There is a gap between the inner side of the cross bar of the gate-shaped rod 2 and the inner wall of the U-shaped tube 1. This avoids friction between the gate-shaped rod 2 and the inner wall of the U-shaped tube 1, and the gate-shaped rod 2 moves more smoothly.

[0025] Among them, a strip hole is opened inside the vertical tube of the U-shaped tube 1, and the cross bar of the gate-shaped rod 2 is penetrated between the two strip holes, and the lower end surface of the cross bar of the gate-shaped rod 2 contacts the lower end surface of the strip hole.

[0026] Working principle:

[0027] When using the utility model, first hold the U-shaped tube 1 and pull the handle 3 hard, so that the cross plate 8 drives the friction plate 9 to move upward, making room for the wire rope 10 to be hooked in the wire hook 6, and release the handle 3. The friction plate 9 is tightly pressed on the wire rope 10 by the downward pulling force of the spring 5. At this time, you can hold the U-shaped tube 1 tightly to overturn the wire rope 10, avoiding direct contact with the wire rope 10 with both hands, which plays a good protective role for both hands. When the utility model does not clamp the wire rope 10, the lower end face of the cross bar of the door-shaped rod 2 is in contact with the lower end face of the strip hole, and the spring 5 is in a natural state at this time.
