Description

Technical Field

[0001] This invention relates to the field of crane technology, and in particular to a crane rope winding device and winding method. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. It is also called an overhead crane, gantry crane, or hoist. The main characteristics of a tire-mounted crane are: its driver's cab and lifting control cab are combined into one unit; it evolved from a crawler crane, replacing the tracks and traveling support of the crawler mechanism with a tire-mounted chassis, overcoming the road damage caused by the tracks of crawler cranes. It belongs to the category of material handling machinery. Some lifting equipment operates intermittently, meaning that the corresponding mechanisms for picking up, moving, and unloading materials work alternately in a work cycle. As cranes become increasingly widespread in the market, most cranes require a rope winding device to wind up the rope before pulling the goods up; therefore, most cranes are equipped with rope winding devices.

[0003] Existing rope winding devices sometimes result in the newly wound rope pressing against the coiled rope during winding. This can lead to several issues: the newly wound rope may become trapped inside the coiled rope due to the high tension, or the coiled ropes may slip or become misaligned. These situations can cause the goods being pulled by the rope to suddenly drop a certain distance. This sudden drop could cause the rope to break due to the impact, posing a significant safety hazard. Summary of the Invention

[0004] This invention addresses the problem of misalignment and slippage between ropes during the winding process in existing rope winding devices, which can cause the goods being pulled by the ropes to suddenly fall and break due to the large impact force. The invention provides a crane rope winding device and winding method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A crane rope winding device includes a base plate, a winding shaft, an anti-slip shaft, and four fixed seats. The winding shaft and anti-slip shaft are located on the upper side of the base plate, and the fixed seats are all fixed on the upper side of the base plate. Each fixed seat has a through hole on one side, and the winding shaft and anti-slip shaft are rotatably connected to the inside of the through hole. Each winding shaft and anti-slip shaft has a one-way transmission drive assembly on one side. The winding shaft is equipped with a winding load assembly, and the anti-slip shaft is equipped with a rope biting anti-slip assembly. A rope guide assembly is provided between the winding load assembly and the rope biting anti-slip assembly.

[0007] Preferably, the unidirectional transmission drive assembly includes a hydraulic motor, a worm gear is fixedly mounted on the shaft end of the hydraulic motor, two connecting seats are rotatably mounted on the outer periphery of the worm gear, the connecting seats and the hydraulic motor are fixed on one side of the fixed seats, and worm wheels are fixedly mounted on the outer periphery of the take-up shaft and the anti-slip shaft, and the worm wheels are connected to the worm gear through meshing transmission.

[0008] Preferably, the take-up and release bearing assembly includes an I-shaped wheel, which is fixed on the outer periphery of the take-up and release shaft, and a rope hole is provided on one side of the I-shaped wheel.

[0009] Preferably, the anti-slip rope biting assembly includes an anti-slip wheel, which is fixed on the outer periphery of the anti-slip shaft. The outer periphery of the anti-slip wheel is provided with a rope-carrying groove and several equally divided circumferential grooves. Two fixing plates are fixedly provided on the inner side of each groove. A tension spring and a sliding plate are sequentially fixed on one side of each fixing plate. A guide hole is provided on one side of each fixing plate. A guide post is slidably provided on the inner side of each guide hole. One end of the guide post is fixed to one side of the sliding plate. A biting head is fixedly provided on the side of the sliding plate away from the tension spring. A hemispherical groove is provided on the side of the guide post away from the sliding plate. A contact steel ball is rotatably provided on the inner side of each hemispherical groove. A biting-loosening drive semi-ring is provided on both sides of the anti-slip wheel away from each other. The biting-loosening drive semi-ring is fixed on the fixing seat, and the contact steel ball can contact the biting-loosening drive semi-ring.

[0010] Preferably, the rope guiding assembly includes two support plates, both of which are fixed to the upper side of the base plate. An upper guide wheel and a lower guide wheel are rotatably connected between the two support plates, and an arc-shaped guide frame and a guide baffle are fixed between the two support plates.

[0011] Preferably, the upper side of the base plate is provided with a plurality of mounting holes.

[0012] A crane rope winding device, the winding method of which includes the following steps:

[0013] S1. Pass one end of the rope through the rope guide assembly, the rope bite anti-slip assembly, and the rope guide assembly in sequence;

[0014] S2. Secure one end of the rope to the take-up and release load-bearing assembly;

[0015] S3. By controlling the one-way transmission drive assembly on one side of the take-up and release shaft and the one-way transmission drive assembly on the other side of the anti-slip shaft, a certain length of rope is wound onto the take-up and release bearing assembly.

[0016] S4. When it is necessary to retract or extend the rope, the one-way transmission drive assembly on one side of the retracting shaft and the one-way transmission drive assembly on the other side of the anti-slip shaft need to be controlled to cooperate with each other to realize the retraction or extension of the rope.

[0017] The present invention provides a crane rope winding device and winding method, the advantages of which are as follows:

[0018] (1) By setting a base plate, anti-slip shaft, fixed seat, one-way transmission drive component, and rope biting anti-slip component, the present invention has the functions of rope anti-slip and automatic loosening, which can prevent the goods from suddenly falling a certain distance due to the loosening between the coiled ropes, thereby preventing the rope from breaking due to the sudden falling of the goods, which has high safety and can greatly reduce safety hazards.

[0019] (2) By setting a base plate, winding and unwinding shaft, fixed seat, one-way transmission drive assembly, and winding and unwinding bearing assembly, the present invention has the functions of automatic winding and one-way transmission. It can automatically wind and unwind ropes, and can also prevent the I-shaped wheel from being pulled and rotated due to large tension. It can only drive in one direction, which can further improve its safety.

[0020] (3) By setting a base plate, a rope-biting anti-slip component, and a rope-guiding component, the present invention has a rope-guiding function, which can guide the direction of rope movement, ensure the stable movement of the rope, and ensure that the rope-biting anti-slip component can always bite the rope, ensuring that the rope will not detach from the rope-biting anti-slip component, thus having high stability and safety.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Reference Figure 1-6 A crane rope winding device includes a base plate 1 with several mounting holes 26 on its upper side. During use, the base plate 1 can be installed and fixed through the mounting holes 26, ensuring that the base plate 1 will not move during use and facilitating installation. The device also includes:

[0030] The take-up and release shaft 2 and the anti-slip shaft 3 are both located on the upper side of the base plate 1. A one-way transmission drive assembly is provided on one side of each shaft. This assembly includes a hydraulic motor 5, which is connected to an external oil pump via an oil pipe. A worm gear 6 is fixedly mounted on the shaft end of the hydraulic motor 5. Two connecting seats 7 are rotatably mounted on the outer periphery of the worm gear 6. The connecting seats 7 and the hydraulic motor 5 are fixed to one side of a fixed seat 4. Worm wheels 8 are fixedly mounted on the outer periphery of both the take-up and release shaft 2 and the anti-slip shaft 3. The worm wheels 8 are meshed with the worm gear 6 for transmission. In use, when rotation of the take-up and release shaft 2 or the anti-slip shaft 3 is required, the corresponding hydraulic motor 5 can be controlled to rotate. When the hydraulic motor 5 rotates, it drives the worm gear 6 to rotate, which in turn drives the worm wheel 8 to rotate. The worm wheel 8 then drives the take-up / release shaft 2 or the anti-slip shaft 3 to rotate, thus enabling automatic drive. During operation, only the worm gear 6 can drive the worm wheel 8 to rotate, while the worm wheel 8 cannot drive the worm gear 6. This achieves unidirectional transmission and prevents the take-up / release shaft 2 and the anti-slip shaft 3 from rotating due to the tension of the rope. The take-up / release shaft 2 and the anti-slip shaft 3 can only be driven by the corresponding hydraulic motor 5. Even if the hydraulic motor 5 is damaged during use, the goods will not fall, providing a high level of safety.

[0031] Four fixed seats 4 are fixed to the upper side of the base plate 1. Each fixed seat 4 has a through hole on one side. The take-up and release shaft 2 and the anti-slip shaft 3 are rotatably connected to the inside of the through hole. The take-up and release shaft 2 is equipped with a take-up and release bearing assembly, which includes an I-shaped wheel 9. The I-shaped wheel 9 is fixed to the outer circumference of the take-up and release shaft 2. One side of the I-shaped wheel 9 is equipped with a rope hole 10. In use, one end of the rope needs to be passed through the rope hole 10 and then fixed to the I-shaped wheel 9. When the I-shaped wheel 9 is rotated, the rope can be wound up on the I-shaped wheel 9. When the take-up and release shaft 2 rotates, it will drive the I-shaped wheel 9 to rotate together, thereby realizing automatic winding and automatic unwinding.

[0032] The anti-slip shaft 3 is equipped with a rope-biting anti-slip assembly, which includes an anti-slip wheel 11. The anti-slip wheel 11 is fixed on the outer periphery of the anti-slip shaft 3. The outer periphery of the anti-slip wheel 11 is provided with a rope-carrying groove 12 and several circumferentially divided grooves 13. Two fixing plates 14 are fixedly provided on the inner side of each groove 13. A tension spring 15 and a sliding plate 16 are sequentially fixed on one side of each fixing plate 14. A guide hole is provided on one side of each fixing plate 14. A guide post 17 is slidably provided on the inner side of each guide hole. One end of the guide post 17 is fixed to one side of the sliding plate 16. A clamping head 18 is fixedly provided on the side of the sliding plate 16 away from the tension spring 15. The sliding plate 16 slides in the groove 13. Inside the guide post 17, the tension spring 15, sliding plate 16, and clamping head 18 are located between two fixed plates 14. A hemispherical groove is provided on the side of the guide post 17 away from the sliding plate 16. A contact steel ball 19 is rotatably positioned inside each hemispherical groove. A release drive half-ring 20 is provided on both sides of the anti-slip wheel 11 away from it. The release drive half-ring 20 is fixed to the fixed base 4. The contact steel ball 19 can contact the release drive half-ring 20. During use, the clamping head 18 located between the two release drive half-rings 20 will clamp the rope, while the clamping head 18 not located between the two release drive half-rings 20 will not clamp the rope, thus providing an anti-slip function and preventing the rope from slipping due to loosening. In case of unexpected movement, when it is necessary to rewind or unwind the rope, the anti-slip shaft 3 can be driven to rotate by controlling the corresponding hydraulic motor 5. When the anti-slip shaft 3 rotates, it will drive the anti-slip wheel 11 to rotate as well. When the anti-slip wheel 11 rotates, it will drive the fixed plate 14, tension spring 15, sliding plate 16, guide post 17, clamping head 18, and contact steel ball 19 to rotate as well. As the rotation progresses, some of the contact steel balls 19 will gradually approach and contact the clamping drive half ring 20. After the contact steel balls 19 contact the clamping drive half ring 20, as the anti-slip wheel 11 continues to rotate, the contact steel balls 19 will roll on the clamping drive half ring 20. At this time, the corresponding contact steel balls 19 and guide post 18 will rotate. 17. The sliding plate 16 and the clamping heads 18 also move, and the two clamping heads 18 clamp the rope, while the other part of the contact steel ball 19 gradually disengages and moves away from the loosening drive half-ring 20. When a part of the contact steel ball 19 moves away from the loosening drive half-ring 20, the corresponding sliding plate 16 will move due to the tension of the tension spring 15. This will cause the corresponding clamping head 18 to release the rope, thus achieving automatic tightening and loosening of the rope. When the anti-slip wheel 11 rotates, a part of the clamping head 18 will always be between the two loosening drive half-rings 20, thus ensuring that the rope is always compressed during movement, providing high stability.

[0033] A rope guide assembly is provided between the release and lifting load assembly and the rope biting anti-slip assembly. The rope guide assembly includes two support plates 21, both of which are fixed to the upper side of the base plate 1. An upper guide wheel 22 and a lower guide wheel 23 are rotatably connected between the two support plates 21. An arc-shaped guide frame 24 and a guide baffle 25 are fixed between the two support plates 21. In use, the rope needs to be passed between the upper guide wheel 22 and the arc-shaped guide frame 24, and also between the lower guide wheel 23 and the guide baffle 25. This ensures that the rope can move in a certain direction when it moves, thus ensuring the stability of the rope during movement and ensuring that the rope is always clamped by a portion of the biting head 18.

[0034] A crane rope winding device, the winding method of which includes the following steps:

[0035] S1. Pass one end of the rope through the rope guide assembly, the rope bite anti-slip assembly, and the rope guide assembly in sequence (when passing the rope through the rope bite anti-slip assembly, it is necessary to activate the one-way transmission drive assembly on one side of the anti-slip shaft 3, and then pass one end of the rope through the anti-slip wheel 11 from above, and guide the rope through the anti-slip wheel 11 from below when the anti-slip wheel 11 rotates).

[0036] S2. Secure one end of the rope to the take-up and release load-bearing assembly;

[0037] S3. By controlling the one-way transmission drive assembly on one side of the take-up and release shaft 2 and the one-way transmission drive assembly on one side of the anti-slip shaft 3, a certain length of rope is wound onto the take-up and release bearing assembly.

[0038] S4. When it is necessary to wind up or unwind the rope, the one-way transmission drive assembly on one side of the wind-up / unwind shaft 2 and the one-way transmission drive assembly on one side of the anti-slip shaft 3 need to be controlled to cooperate with each other to achieve the wind-up or unwinding of the rope. (When winding up or unwinding the rope, different hydraulic motors 5 need to be controlled separately. The rotation direction and rotation speed of the hydraulic motors 5 should be controlled separately according to the situation to ensure the wind-up or unwinding of the rope. At the same time, it is also necessary to ensure that the rope between the rope biting anti-slip assembly and the wind-up / unwinding bearing assembly is in a taut state.)
