Description

Technical Field

[0001] The invention relates to the technical field of mechanical engineering, and in particular to an impact-proof automatic cable arrangement mechanism. Background Art

[0002] In the modern industrial field, the rapid development of mechanical engineering technology has provided strong equipment support for material lifting and traction operations in many industries. Among them, winches, cranes, hoists and other systems with cable storage functions play a pivotal role. These equipment are widely used in key operation scenarios such as cargo loading and unloading at ports and terminals, ore mining and transportation in mines, material lifting at construction sites, and anchoring and lifting of ships at sea.

[0003] With the continuous expansion of production scale and the continuous increase of operation intensity in various industries, more stringent requirements are put forward for the reliability, safety and operation efficiency of the above equipment. However, the traditional winch, crane and hoist system has exposed a series of problems that need to be solved in the cable retraction and release process, among which the cable arrangement disorder and impact damage are particularly prominent.

[0004] During the cable winding process, the equipment frequently starts and stops, changes speed, and the load changes are complex, which will cause the cable to be subjected to irregular impact forces. These impact forces can not only easily cause a sharp increase in the instantaneous tension of the cable, causing cable wear and wire breakage, greatly shortening the service life of the cable; they may also cause the cables to stack disorderly on the drum, resulting in rope biting and rope tangling. Once rope tangling occurs, the equipment shutdown and maintenance is time-consuming and labor-intensive, seriously interfering with normal production progress. In extreme cases, the disordered cables may even get stuck in the gaps of the mechanical structure of the equipment, causing damage to key components of the equipment and causing safety accidents.

[0005] Furthermore, most existing cable-laying mechanisms are purely mechanical structures that can only achieve the basic function of arranging cables neatly, and lack effective buffering and intelligent response mechanisms for impact. In the face of sudden impact loads, this type of traditional cable-laying mechanism cannot quickly adjust the cable tension and cable-laying action, making it difficult to ensure that the cables are always neatly and orderly wound around the drum. Summary of the invention

Guide rod copper sleeves are respectively provided between the inner walls of the other two through holes and the corresponding slide rods, and the guide rod copper sleeves are installed in the through holes through copper sleeve cover covers.

[0034] The main guide wheel 3 is installed on the slide assembly 1 through the main guide wheel seat 2. The slide assembly 1 includes a slide body, a slide rod 5, a ball screw pair, a reducer 7, and a servo motor 8. The servo motor 8 is connected to the ball screw pair through the reducer 7. Two slide rods 5 are provided, which are installed in parallel and at intervals on opposite sides of the ball screw pair's lead screw 6. The slide body is connected to the ball screw pair, and the slide rod 5 and the lead screw 6 are respectively penetrated in the slide body.

[0035] The slide body includes a slide body 1-1, an auxiliary guide wheel mounting seat 1-3, and a rotatable spring hinge support 1-4. The slide body 1-1 is provided with three through holes at intervals in sequence, which are used to pass the slide rod 5 and the screw rod 6 respectively, and the screw nut 1-7 of the ball screw pair is connected to the through hole in the middle. A guide rod copper sleeve 1-5 is respectively provided between the inner walls of the other two through holes and the corresponding slide rods 5, and the guide rod copper sleeve 1-5 is installed in the through hole through a copper sleeve cover 1-6. The auxiliary guide wheel mounting seat 1-3 and the rotatable spring hinge support 1-4 are respectively installed on the adjacent two side surfaces of the slide body 1-1. The side surface of the slide body 1-1 opposite to the rotatable spring hinge support 1-4 is the main guide wheel seat mounting surface 1-2, and the main guide wheel 3 is installed on the main guide wheel seat mounting surface 1-2 through the main guide wheel seat 2. A lubrication oil injection hole 1-8 is also provided on the slide body 1-1. The main guide wheel counter 4 is installed on the main guide wheel seat 2, the proximity switch 9 is installed on one end of the ball screw pair and faces the slide body 1-1, and the screw fine-tuning rod 16 is installed on the ball screw pair.

[0036] The anti-impact mechanism is arranged below the main guide wheel 3 and connected to the slide assembly 1. The anti-impact mechanism includes an auxiliary guide wheel 10, an anti-impact rocker 11, an anti-impact transition pulley 12, a rotatable spring seat 13, a rotatable spring seat 2 14, and a spring 15. The rotatable spring seat 2 14 is connected to the rotatable spring hinge support 1-4, and the auxiliary guide wheel 10 and the anti-impact rocker 11 are respectively connected to the auxiliary guide wheel mounting seat 1-3. One end of the spring 15 is connected to the slide assembly 1 through the rotatable spring seat 2 14, and the other end is connected to the rotatable spring seat 1 13. The anti-impact transition pulley 12 is installed on the rotatable spring seat 1 13 and connected to the auxiliary guide wheel mounting seat 1-3 through the anti-impact rocker 11.

[0037] The rotatable spring seat 13 has the same structure as the rotatable spring seat 2 14, and the lateral length of the rotatable spring seat 13 is greater than the lateral length of the rotatable spring seat 2 14. The rotatable spring seat 2 14 includes a hinge support, a spring guide rod 14-2, and a spring guide rod fixing nut 14-3. Two protrusions are vertically and parallelly spaced on the hinge support, and symmetrical hinge support connecting holes 14-1 are provided on the two protrusions.

The spring guide rod 14-2 has a guiding effect on the spring 15. Two springs 15 are provided and are installed between the rotatable spring seat 13 and the rotatable spring seat 2 14 in parallel and spaced.

[0038] During normal operation, the slide body is driven by the servo motor 8 through the reducer 7 to rotate the lead screw 6 and move along the slide rod, thereby realizing the automatic cable arrangement function, and its movement speed is controlled by the servo motor; the main guide wheel counter 4 is used to calculate the retracted and released length of the cable during operation; the proximity switch 9 is used to limit the movement range of the slide body; the lead screw fine-tuning rod is used to adjust the position of the lead screw and the slide body.

[0039] When the cable is being retracted Figure 8 As shown in (a), the anti-impact transition pulley is in a balanced state under the action of the cable tension and the elastic force of the spring. When the cable is impacted, the cable tension increases, so the force acting on the anti-impact transition pulley also increases. The force on the pulley will inevitably compress the spring to increase the elastic force and reach a new balance. Figure 8 As shown in (b) and (c), when the spring is compressed, it will inevitably move. Due to the displacement, the cable will relax and its tension will inevitably decrease, thus forming a dynamic balance, which prevents the cable and equipment parts from being suddenly impacted and damaged by external forces.

[0040] The present invention is precisely positioned in the field of mechanical engineering technology. It has devoted itself to the research and design of an impact-proof automatic cable-laying mechanism, which cleverly integrates buffering and shock-absorbing technology with precise cable-laying control strategy. It can fully resist the impact encountered when the cable is retracted and released, ensuring that the cable can be reeled and released smoothly and orderly, laying a solid foundation for the safe and efficient operation of winches, cranes, hoists and other equipment, and helping to smoothly and efficiently advance the operating processes of various industries.
