Description

Technical Field

[0001] This utility model relates to the technical field of wire rope anti-derailment devices, and in particular to wire rope anti-derailment devices for overhead crane hooks. Background Technology

[0002] During construction, the excavation and transportation of excavated soil inevitably generate a large amount of dust. Dust pollution is the most significant air pollutant. To prevent and control air pollution, existing technologies often use water spraying devices to reduce dust in the air. However, this method can cause the ground to become slippery, affecting the construction progress. Therefore, it can only be operated after construction has stopped. Moreover, water spraying alone cannot purify the air and its effect on preventing and controlling air pollution is generally limited.

[0003] When assembling or disassembling C-hooks, the wire rope is prone to slipping out of the groove. This is due to unreasonable pulley design of the lifting equipment, lack of effective anti-slip structure, or improper operation by the crane operator during lifting operations, such as sudden stops, sudden turns, or oblique pulling, which may cause the wire rope to swing violently in the pulley, thus slipping out of the groove.

[0004] Therefore, in response to the problem that the wire rope is prone to derailment when the crane operator disassembles and assembles the C-type hook, which may cause the wire rope to swing violently in the pulley and thus derail, a device to prevent the wire rope from derailing can be designed for the crane hook. Utility Model Content

[0005] To overcome the problem that the wire rope is prone to slipping out of the groove when the crane operator is disassembling and assembling the C-hook, which may cause the wire rope to swing violently in the pulley and thus slip out of the groove.

[0006] The technical solution of this utility model is as follows: a crane hook wire rope anti-derailment device, including a base plate and a steel pipe; it also includes an anti-derailment component and a guide component. A steel pipe is set at the middle position of the top of the base plate, and an anti-derailment component is installed at the top of the steel pipe. A guide component is set at the top of the base plate and is installed on both sides of the steel pipe. The anti-derailment component includes a mounting bracket, which is installed at the top of the steel pipe. A limit spring is installed at the bottom of the mounting bracket, and a rubber anti-derailment baffle is set at the top of the limit spring and is located above the steel pipe.

[0007] Preferably, the anti-detachment baffle, under the action of the limiting spring, tightly adheres to the surface of the wire rope, applying a certain pressure to prevent it from moving out of the groove.

[0008] As a preferred embodiment, the bottom end of the anti-detachment baffle is provided with an anti-detachment groove, the top ends of the steel pipes are provided with guide rollers, and the front end of the mounting bracket is provided with a control display screen.

[0009] Preferably, a guide turntable is installed on the left side of the steel pipe, and a guide groove is opened inside the guide turntable.

[0010] Preferably, the guide assembly includes a fixing block disposed on the rear side of the top of the base plate, and a rotating rod is mounted on the top of the fixing block.

[0011] Preferably, a rotating cylinder is rotatably connected to the outer side of the rotating rod, and a U-shaped plate is installed on the left side of the rotating cylinder.

[0012] Preferably, the top of the base plate is mounted with a support frame, and the support frame is located on the opposite side of the steel pipe, with the rotating cylinder located on the top of the left support frame.

[0013] Preferably, the uprights are connected by threaded rods, which are located at the front and rear ends of the steel pipe, and the inside of the steel pipe is provided with grooves.

[0014] The beneficial effects of this utility model are as follows: By setting the limiting spring and the anti-derailment baffle, the wire rope can be adaptively adjusted according to the real-time displacement. When the wire rope tends to derail, it is pulled back to the normal position, continuously maintaining the stability of the wire rope in the pulley groove, effectively reducing the risk of derailment, and at the same time alleviating the instantaneous impact force on the wire rope, reducing the damage to the wire rope and pulley caused by rigid collision, and extending the service life of both.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 - Figure 4 This utility model provides an embodiment of an anti-derailment device for a crane hook wire rope, comprising a base plate 1 and a steel pipe 2; it also includes an anti-derailment component and a guide component. The steel pipe 2 is disposed at the middle position of the top of the base plate 1, the anti-derailment component is installed at the top of the steel pipe 2, and the guide component is disposed at the top of the base plate 1 and is installed on both sides of the steel pipe 2. The anti-derailment component includes a mounting bracket 301, which is installed at the top of the steel pipe 2. A limit spring 302 is installed at the bottom of the mounting bracket 301, and a rubber anti-derailment baffle 303 is disposed at the top of the limit spring 302 and is disposed above the steel pipe 2.

[0022] Please see Figure 3 In this embodiment, the bottom end of the anti-detachment baffle 303 is provided with an anti-detachment groove 304, and the top ends of the steel pipes 2 are respectively provided with guide rollers 305. The front end of the mounting bracket 301 is provided with a control display screen 306. A guide turntable 307 is installed on the left side of the steel pipe 2. The guide turntable 307 is provided with a guide groove 308. After the connection is made, the operator will clamp the wire rope into the guide groove 308 on the guide turntable 307, and at the same time pass through the lower end of the anti-detachment baffle 303 and cross through to the guide roller 305, so that the steel pipe 2 is connected to the wire rope.

[0023] Please see Figure 2 , Figure 4 In this embodiment, the guide assembly includes a fixing block 401, which is located on the rear side of the top of the base plate 1. A rotating rod 402 is installed on the top of the fixing block 401. A rotating drum 403 is rotatably connected to the outer side of the rotating rod 402. A U-shaped plate 404 is installed on the left side of the rotating drum 403. A support frame 405 is installed opposite to the top of the base plate 1, and the support frame 405 is located on the opposite side of the steel pipe 2. The rotating drum 403 is located on the top of the left support frame 405. Threaded rods 406 are threadedly connected between the support frames 405, and the threaded rods 406 are located at the front and rear ends of the steel pipe 2. The inside of the steel pipe 2 is provided with slots 407. The rotating drum 403 is rotated to a suitable angle according to the size of the pulley, so that the U-shaped groove on the U-shaped plate 404 is engaged with the inner side of the pulley rim, ensuring that the wire rope is confined within the space formed by the U-shaped plate 404 and the pulley during normal operation, preventing it from slipping out of the groove.

[0024] During operation, the drum 403 is rotated to a suitable angle according to the pulley's specifications, so that the U-shaped groove on the U-shaped plate 404 engages with the inner side of the pulley rim. This ensures that the wire rope is confined within the space formed by the U-shaped plate 404 and the pulley during normal operation, preventing it from slipping out of the groove. After the connection is made, the operator engages the wire rope in the guide groove 308 on the guide turntable 307, and simultaneously passes it through the lower end of the anti-slip baffle 303, crossing it into the guide roller 305, so that the steel pipe 2 is fitted onto the wire rope. When the wire rope is running normally, the anti-slip baffle 303, under the action of the limit spring 302, tightly adheres to the surface of the wire rope, applying a certain pressure to prevent it from moving out of the groove. When the wire rope is subjected to a sudden impact force or tends to slip out of the groove due to oblique pulling or tilting, the anti-slip baffle 303 can flexibly deform under the buffering action of the limit spring 302, always maintaining the constraint on the wire rope and preventing it from slipping out of the groove.

[0025] Through the above steps, with the cooperation of the limit spring 302 and the anti-derailment baffle 303, adaptive adjustment can be made according to the real-time displacement of the wire rope. When the wire rope tends to derail, it is pulled back to the normal position, continuously maintaining the stability of the wire rope in the pulley groove. At the same time, it alleviates the instantaneous impact force on the wire rope, reduces the damage to the wire rope and pulley caused by rigid collision, and extends the service life of both. This solves the problem that when crane operators disassemble and assemble C-type hooks, the wire rope is prone to derailment, which may cause the wire rope to swing violently in the pulley and thus derail.
