Description

Technical Field

[0001] This utility model belongs to the field of wire rope anti-derailment technology, and in particular relates to a wire rope grab structure. Background Technology

[0002] In actual operation scenarios of grab buckets, the wire rope frequently becomes detached from the upper and lower pulleys (pulleys).

[0003] When the grab bucket performs cyclical actions such as grabbing, lifting, and unloading materials, the complex working conditions can easily cause the wire rope to shift momentarily within the pulley groove. This can also cause the relative position between the wire rope and the pulley to change continuously, making it easy for the wire rope to come out of the rope groove of the upper and lower pulleys, interrupting the operation process, increasing the frequency of equipment maintenance and the risk of material spillage, and reducing the overall operating efficiency. To address this, we have proposed a wire rope grab bucket structure. Utility Model Content

[0004] The purpose of this utility model is to provide a wire rope grab structure. By setting an anti-rope slippage mechanism, specifically, the lower pulley and other structures work together to drive the grab to close inward and grab the material, transferring the material to a predetermined position. During the lowering of the wire rope, the wire rope passes through the hollow tube in sequence. The hollow tube can effectively limit the wire rope, preventing it from slipping off due to excessive lowering, thus improving work efficiency. This solves the problem that existing wire ropes are prone to slipping out of the rope grooves of the upper and lower pulleys, interrupting the operation process, increasing equipment maintenance frequency and the risk of material spillage, and reducing overall operation efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The outer surfaces of the upper hollow tube and the lower hollow tube are in contact with hinge rings. The bottom of the collection module is fixedly connected to two support frames. The bottom of the support frame is fixedly connected to a connecting frame. The anti-detachment rope mechanism is used to provide a support foundation for the hollow tubes.

[0008] A lubrication mechanism is provided inside the anti-derailment mechanism and is used to lubricate the inside of the anti-derailment mechanism; the support frame is used to provide a support base for the connecting frame located above.

[0010] A fixing component is used to fix the hollow tube; a limiting component is used to control the position of the released wire rope and to provide a supporting foundation for the internal structure of the fixing component.

[0011] Furthermore, the lubrication mechanism includes two rings respectively installed at the top and bottom of the hollow tube, the rings being used to guide the wire rope.

[0012] Furthermore, the limiting assembly includes two fixing rings respectively installed on the front and back of the connecting frame, wherein the side of the fixing ring away from the connecting frame is hinged to the side of the hinge ring near the connecting frame; the fixing ring is used to provide a hinge fulcrum for the hinge ring.

[0013] Furthermore, the fixing assembly includes an inner plate installed on the inner side of the lower crossbeam. Two support frames are fixedly connected to the top of the inner plate. The top of the support frames is fixedly connected to the top of the connecting frame located below. A bolt is threaded inside the hinge ring. The bolt passes through the interior of the hinge ring and is threaded inside the fixing ring. The hinge ring is used to limit the hollow tube.

[0014] Furthermore, the lubrication mechanism includes an oil injection pipe installed on the outer surface of the hollow tube, a pressing column slidably connected inside the oil injection pipe, two external rings fixedly connected to the outer surface of the oil injection pipe, a limiting column fixedly connected inside the oil injection pipe, a spring provided on the outer surface of the limiting column, an annular groove opened inside the oil injection pipe, and a plurality of oil injection holes opened inside the oil injection pipe, the oil injection holes communicating with the annular groove.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates an anti-rope slippage mechanism.

The bottom of the collection module 11 is fixedly connected to the upper crossbeam 1. It also includes: an anti-derailment mechanism 2, located below the upper crossbeam 1, comprising several hollow tubes 211. The outer surfaces of both the upper and lower hollow tubes 211 are in contact with hinge rings 223. Two support frames 214 are fixedly connected to the bottom of the collection module 11, with connecting frames 212 fixedly connected to their bottoms. The anti-derailment mechanism 2 provides a support base for the hollow tubes 211. A lubrication mechanism 3 is located inside the anti-derailment mechanism 2 and is used to lubricate the interior of the anti-derailment mechanism 2. Support frames 214... 14 provides a supporting foundation for the connecting frame 212 located above. The anti-rope detachment mechanism 2 includes a limiting component 21 located below the upper crossbeam 1, which limits the wire rope; a fixing component 22, which fixes the hollow tube 211; the limiting component 21 controls the position of the released wire rope and provides a supporting foundation for the internal structure of the fixing component 22. The sliding wheel and other structures work together to drive the grab bucket to close inward to grab the material and transfer it to the predetermined position. During the process of lowering the wire rope, the wire rope will pass through the hollow tube 211 in sequence. The hollow tube 211 can effectively limit the wire rope, avoid the phenomenon of rope detachment caused by excessive lowering of the wire rope, and improve work efficiency.

[0029] Lubrication mechanism 3 includes two rings 36 respectively installed at the top and bottom of hollow tube 211. The rings 36 are used to guide the wire rope. Limiting assembly 21 includes two fixing rings 213 respectively installed on the front and back of connecting frame 212. The side of fixing ring 213 away from connecting frame 212 is hinged to the side of hinge ring 223 near connecting frame 212. Fixing ring 213 is used to provide hinge fulcrum for hinge ring 223. Fixing assembly 22 includes an inner plate 221 installed inside the lower crossbeam 12. Two support frames 222 are fixedly connected to the top of the inner plate 221. The top of support frames 222 is fixedly connected to the top of the connecting frame 212 located below. Bolt 224 is threaded inside hinge ring 223. Bolt 224 passes through the inside of hinge ring 223 and is threaded inside fixing ring 213. The hinge ring 223 is used to limit the hollow tube 211. The lubrication mechanism 3 includes an oil injection pipe 31 installed on the outer surface of the hollow tube 211. A pressing post 32 is slidably connected inside the oil injection pipe 31. Two external rings 33 are fixedly connected to the outer surface of the oil injection pipe 31. A limiting post 34 is fixedly connected inside the oil injection pipe 31. A spring 35 is provided on the outer surface of the limiting post 34. An annular groove is opened inside the oil injection pipe 31. Several oil injection holes 37 are opened inside the oil injection pipe 31. The oil injection holes 37 communicate with the annular groove. When the oil injection chamber is opened, lubricating oil is introduced into the oil injection pipe 31 using a tool. Then the lubricating oil slides into the annular groove, slides into the oil injection hole 37, and slides into the inner wall of the oil injection pipe 31 from the oil injection hole 37 to lubricate the inner wall of the oil injection pipe 31 and reduce the friction between the oil injection pipe 31 and the wire rope.

[0030] A specific application of this embodiment is as follows: First, take the hollow tube 211, flip the hinge ring 223 outward, and place the hollow tube 211 inside the fixing ring 213. At this time, reset the hinge ring 223, and tighten the bolt 224 with a screwdriver to fix the fixing ring 213 and the hinge ring 223 together. Pass the wire rope through the inside of the upper hollow tube 211, enter the inside of the lower hollow tube 211, and go around the pulley. Then, pass the wire rope through the inside of the other side of the lower hollow tube 211 to the upper pulley. Next, press the pressing column 32 into the oil injection pipe 31. The pressing column 32 moves into the oil injection pipe 31 and compresses the spring 35. The spring 35 accumulates elastic force until the oil injection chamber is opened. Use a tool to introduce lubricating oil into the oil injection pipe 31. Next, the lubricating oil slides into the annular groove, into the oil injection hole 37, and into the inner wall of the oil injection pipe 31 to lubricate the inner wall of the oil injection pipe 31, reducing the friction between the oil injection pipe 31 and the wire rope. The equipment is then moved to the predetermined position, and the grab bucket is moved above the material. Then, the collection module 11 is activated to collect the wire rope. The collection of the wire rope will drive the sliding wheel to move upward. The sliding wheel and other structures work together to drive the grab bucket to close inward to grab the material and transfer it to the predetermined position. During the process of lowering the wire rope, the wire rope will pass through the hollow tube 211 in sequence. The hollow tube 211 can effectively limit the wire rope and prevent the wire rope from detaching due to excessive lowering.
