Description

Technical Field

[0001] This invention relates to the field of safety protection technology for wire rope winding and unwinding, and in particular to a galvanized wire rope anti-derailment limiting device. Background Technology

[0002] Galvanized steel wire rope, with its excellent corrosion resistance and wear resistance, is widely used in hoisting, transportation, construction, and other fields. During use, it is typically wound up and unwound using rollers to ensure orderly transport and storage. However, most galvanized steel wire rope winding and unwinding devices on the market currently suffer from poor anti-derailment and limiting effects. During the winding and unwinding process, improper operation, vibration, impact, or device design flaws can easily lead to wire rope slackness, lateral deviation, and even derailment or detachment from the rollers. This can damage the wire rope and equipment, and may even cause safety accidents. Existing anti-detachment devices are mostly fixed structures, which cannot flexibly adjust the clamping and limiting force according to galvanized steel wire ropes of different diameters, resulting in poor adaptability. Some adjustable devices have complex structures, are inconvenient to adjust, and lack adaptive fitting mechanisms, making it difficult to adapt to different positions on the outside of the wound steel wire rope. This can easily lead to clamping gaps or over-clamping, either failing to effectively prevent detachment or wearing down the steel wire rope. At the same time, their guide mechanisms are poorly designed, failing to provide precise guidance for the winding and unwinding of the steel wire rope, further increasing the risk of detachment. They are unable to meet the safety requirements of actual production. Therefore, developing a galvanized steel wire rope anti-detachment limiting device with strong adaptability, reliable anti-detachment effect, and convenient adjustment has important practical significance and application value.

The adjustment component 437 includes a guide hole seat 4371, a guide hole 4372, a screw 4373, a telescopic seat 4374, and a connecting hole block 4375.

[0031] like Figure 6 and Figure 7As shown, the adaptive chuck 6 includes a mounting base 61, a mounting groove 62, a fixing cover 63, pressure plates 64, a limiting protrusion 65, an elastic clamping assembly 66, and a connecting cavity 67. The mounting base 61 has a vertically connected mounting groove 62 inside. The fixing cover 63 is detachably fixed to the upper side of the mounting base 61 by bolts, and the fixing cover 63 has a through-type connecting cavity 67 extending longitudinally (parallel to the axis of the roller 2). There are 10-30 pressure plates 64, arranged longitudinally and movably connected to the inside of the mounting groove 62, with a 0.1-0.2mm gap between adjacent pressure plates 64. The vertical width of each pressure plate 64 is 0.6-0.8 times the diameter of the galvanized steel wire rope to which it is adapted. Each of the pressure plates 64 has an integrally extended limiting groove 65 on the upper left and right sides, making the pressure plate 64 have a "T" shaped cross section. The outer side of the limiting groove 65 forms a clearance fit with the left and right vertical guide inner walls of the connecting cavity 67 and can slide relative to each other. Each of the pressure plates 64 has an elastic clamping component 66 fixedly connected inside the upper two sides. That is, each pressure plate 64 corresponds to two symmetrically distributed elastic clamping components 66, and the top of all elastic clamping components 66 abuts against the horizontal top wall of the connecting cavity 67.

[0032] The pressure plate 64 and the limiting groove 65 are integrally cast or milled.

[0033] like Figure 8 As shown, the elastic clamping assembly 66 includes a push rod 661, a blind hole 662, a clamping spring 663, a fixed housing 664, and a connecting hole 665. The fixed housing 664 is a cylindrical housing with an axial connecting hole 665 inside its upper side. The outer side of the fixed housing 664 is fixedly embedded in the pre-opened circular mounting grooves on both sides of the upper side of the pressure plate 64 by an interference fit. The push rod 661 is a shaft structure, with its lower rod body externally connected to the inside of the connecting hole 665. The upper end of the push rod 661 is a plane and contacts the horizontal top wall surface of the connecting cavity 67. The lower side of the push rod 661 has an axial blind hole 662 inside, and a pre-compressed clamping spring 663 is provided between the bottom surface of the blind hole 662 and the bottom surface of the lower side of the connecting hole 665. The two ends of the clamping spring 663 abut against the bottom surface of the blind hole 662 and the bottom surface of the connecting hole 665, respectively.

[0034] The invention is used in the following ways: The invention has a reasonable and simple structure, low production cost, convenient installation, and complete functions. Before use, the motor 3 is in a power-off and stopped state, its output shaft is stationary, and the roller 2, which is fixedly connected to the output shaft of the motor 3, remains stationary. The surface of the roller 2 can be pre-wound with galvanized steel wire rope to be unwound. The adjustable clamping mechanism 4 is in its initial reset state, the guide groove seat 41 is fixed inside the upper side of the mounting base 1, and the slider 44 and slider 47 in the guide groove 42 (T-shaped guide groove) are driven by the natural tension of the tension springs 45 and 46 to clamp the two adaptive clamps 6 tightly. The galvanized steel wire rope is wound around the outside of the drum 2; two guide rollers 7 are movably connected to the two sides of the lower center inside the mounting base 1, maintaining a horizontal rotation state, and their surfaces are in a preset contact position with the galvanized steel wire rope to be passed through, providing guidance and support for the wire rope conveying; at this time, the elastic clamping component 66 inside the self-adaptive chuck 6 is in a natural extension and retraction state, the pressure plate 64 is kept in a clamping state under the action of the clamping spring 663, and the limiting protrusion 65 is in contact with the inner wall of the connecting cavity 67 to ensure the stability of the pressure plate 64; when the galvanized steel wire rope needs to be wound or unwound, the motor 3 is started, and the output shaft of the motor 3... The roller 2 rotates inside the mounting base 1, and during the rotation of the roller 2, the wire rope is wound, stored, or released and conveyed. At this time, the galvanized wire rope passes between the two guide rollers 7. The guide rollers 7 rotate synchronously under the friction of the wire rope, which guides and limits the wire rope, preventing lateral deviation during the conveying process and providing precise guidance for subsequent anti-detachment clamping. At the same time, according to the actual diameter and usage of the galvanized wire rope, the clamping force of the two adaptive clamps 6 is adjusted by the adjustable clamping mechanism 4 to ensure the clamping effect. Specifically, during adjustment, symmetrical adjustment is initiated first. The motor 434 in mechanism 43 has an output shaft that drives the transmission shaft 435 to rotate inside the upper side of the guide slot seat 41. The transmission gear 433 and transmission gear 438 on the left and right sides of the transmission shaft 435 rotate synchronously. The transmission gear 433 meshes with the driven gear 432 on the left side of the adjustment component 431, driving the screw 4373 of the adjustment component 431 to rotate. The transmission gear 438 meshes with the driven gear 4311 on the right side of the adjustment component 437 through the connecting gear 4310, driving the screw 4373 of the adjustment component 437 to rotate synchronously.In adjusting components 1 (431) and 2 (437) (which have identical structures), the screw 4373 rotates within the guide hole 4372 of the guide hole seat 4371. The telescopic seat 4374, threadedly connected to the screw 4373, moves laterally along the guide hole 4372. If the wire rope diameter is large, the telescopic seat 4374 moves inward, pulling the tension springs 1 (45) and 2 (46) through the connecting hole block 4375. This stretches the tension springs 1 (45) and 2 (46), increasing the pulling force of the sliders 1 (44) and 2 (47), thus achieving the clamping effect after winding a larger diameter wire rope and preventing the wire rope from loosening or detaching. If the wire rope diameter is small, the telescopic seat 4374 moves outward, causing the tension springs 1 (45) and 2 (46) to contract, thus reducing the pulling force of the sliders 1 (44) and 2 (47). This avoids excessive clamping force affecting the loosening of smaller diameter wire ropes. The adaptive clamp 6 can adaptively fit different positions on both sides of the wire rope surface wound on the drum 2. Here, the push rod 661 moves upward along the connecting hole 665 of the fixed housing 664, and the clamping spring 663 is compressed between the blind hole 662 and the connecting hole 665, generating a reverse clamping force, pushing the pressure plate 64 to fit tightly against the corresponding position on the wire rope surface. Since the pressure plate 64 and the limiting protrusion 65 are made as one piece, the limiting protrusion 65 slides along the inner wall of the connecting cavity 67, ensuring that the pressure plate 64 does not shift during movement. Several longitudinally arranged pressure plates 64 can adapt to different positions on the outside of the wound wire rope, achieving all-round adaptive clamping and avoiding gaps that could cause the wire rope to detach during winding and unwinding.
