Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to hoisting equipment for cable production. Background Art

[0002] In the modern cable manufacturing industry, the cable production process involves multiple stages, including the stretching of wires, the addition of insulation layers, the application of sheaths, and the winding and transportation of finished cables. When transporting over short distances, lifting equipment is required.

[0003] Publication No. CN220283286U discloses a cable unhooking static load hoisting device, including a hoisting frame, a hoisting hook and a unhooking assembly; the hoisting frame is provided with a hoisting area, and the hoisting area is connected to the hoisting lifting equipment; the hoisting hook is suspended below the hoisting frame through a hanging rope chain; the unhooking assembly includes a driving member and an unhooking rope chain, the driving member is arranged on the hoisting frame and is provided with a movable end, one end of the unhooking rope chain is connected to the movable end of the driving member, and the other end of the unhooking rope chain is connected to the hoisting hook structure between the bottom of the hoisting hook and the hook tip. Although this type of hoisting device avoids the operator being around the object during unhooking and improves the safety of personnel during the unhooking process, this type of hoisting device fails to effectively prevent the cable from accidentally falling off when subjected to tension in different directions during the hoisting process, especially when encountering sudden force changes or unbalanced hoisting conditions, and due to the lack of automatic adjustment and anti-falling protection mechanism, the existing cable hoisting equipment requires more manual intervention during operation, which not only increases the difficulty of operation, but also reduces the efficiency and safety of operation. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems raised in the above background technology.

[0005] The utility model adopts the following technical scheme: a hoisting device for cable production, comprising a hoisting frame, an electric hoist is fixedly installed on the top surface of the hoisting frame, a hanging rope chain is installed on the surface of the electric hoist, a stopper is fixedly installed on the bottom end of the hanging rope chain, a cylinder is slidably connected to the surface of the hanging rope chain, a spring is sleeved on the surface of the hanging rope chain, a hoisting hook is fixedly installed on the bottom end of the cylinder, and an annular frame is fixedly installed on the surface of the stopper.

[0006] Preferably, the top end of the spring contacts the cylinder, and the bottom end of the spring contacts the stopper.

[0007] Preferably, a clamping block is fixedly mounted on the inner side of the annular frame, and the material of the clamping block is austenitic stainless steel. Here, the structural strength of the clamping block can be improved.

[0008] Preferably, a mounting plate is fixedly mounted on the side of the hanging frame, and a mounting hole is provided on the bottom surface of the mounting plate. Here, the hanging frame can be conveniently installed and fixed.

[0009] Preferably, there are two groups of mounting plates, and the two groups of mounting plates are symmetrically distributed on both sides of the hanging frame.

[0010] Preferably, a protective mechanism is provided on the inner side of the lifting hook, and the protective mechanism includes a circular hole, the circular hole is opened on the inner side of the lifting hook, a gasket is fixedly installed on the inner wall of the circular hole, a round block is provided inside the circular hole, and a protective sheet is fixedly installed on the top of the round block. Here, the cable can be prevented from being worn.

[0011] Preferably, the material of the protection sheet is natural rubber, and the shape of the protection sheet is the same as that of the hoisting hook. Here, the service life of the protection sheet can be increased.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when actually used, the cable is wound into a loop. When hoisting, the cable loop is hung on the hoisting hook, and then the electric hoist drives the hanging rope chain to move, and the hanging rope chain then drives the hoisting hook to move. The hoisting hook can then lift the cable to hoist the cable, and when the hoisting hook is subjected to an upward pulling force, the hoisting hook can drive the cylinder to move downward, and the cylinder can squeeze the spring at this time. At this time, the spring is compressed, and at the same time, the cylinder drives the hoisting hook to move downward, and the annular frame moves upward relative to the hoisting hook. The annular frame can extend upward at this time, and the annular frame can block the gap above the hoisting hook. In this way, during the process of lifting the cables, the probability of the cables falling off the lifting hook can be reduced. The utility model introduces a mechanism in which the annular frame blocks the gap above the lifting hook, thereby significantly reducing the risk of the cables falling off during the lifting process. Through the interactive mechanism between the lifting hook, the cylinder and the spring, the functions of automatically compressing the spring, moving the cylinder downward, and extending the annular frame upward when subjected to upward pulling force are realized. This automatic adjustment function enables the utility model to automatically adjust the protective structure according to the actual force changes during the lifting process, thereby increasing the convenience of use and the stability of cable lifting, and having high practicality.

[0014] 2. In the utility model, during actual use, the protective sheet is provided. Since the material of the protective sheet is natural rubber, which is relatively soft, when hoisting the cable, direct hard contact between the hoisting hook and the cable can be avoided to cause cable wear. When the protective sheet is severely worn and needs to be replaced, the staff only needs to pull the protective sheet outward, and the protective sheet then drives the round block out of the round hole. At this time, the protective sheet can be removed. When installing the protective sheet, it is only necessary to align the round block under the protective sheet with the round hole and insert it. After the round block is squeezed into the round hole, the friction force applied by the gasket can fix the protective sheet, which has the effect of facilitating the replacement and maintenance of the protective sheet. The utility model can effectively reduce the hard wear caused by direct contact by adding a protective sheet made of natural rubber between the hoisting hook and the cable. The natural rubber has good elasticity and softness, and can absorb some impact and friction during the operation process, thereby protecting the cable surface from damage.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] See also Figure 1-5 The utility model provides a technical solution: a hoisting device for cable production, including a hoisting frame 1, a mounting plate 10 is fixedly installed on the side of the hoisting frame 1, the number of the mounting plates 10 is two groups, the two groups of mounting plates 10 are symmetrically distributed on both sides of the hoisting frame 1, and mounting holes 11 are opened on the bottom surface of the mounting plate 10. An electric hoist 2 is fixedly installed on the top surface of the hoisting frame 1, and the electric hoist 2 can perform lifting work. A hanging rope chain 3 is installed on the surface of the electric hoist 2, and a stopper 4 is fixedly installed on the bottom end of the hanging rope chain 3. A cylinder 5 is slidably connected to the surface of the hanging rope chain 3.

[0026] See also Figure 1-5 The surface of the hanging rope chain 3 is sleeved with a spring 6, the top end of the spring 6 contacts the cylinder 5, the bottom end of the spring 6 contacts the stopper 4, and a lifting hook 7 is fixedly installed at the bottom end of the cylinder 5 to wind the cable into a circle. During lifting, the cable circle is hung on the lifting hook 7, and then the electric hoist 2 drives the hanging rope chain 3 to move, and the hanging rope chain 3 then drives the lifting hook 7 to move. The lifting hook 7 can then lift the cable to lift the cable. A ring frame 8 is fixedly installed on the surface of the stopper 4. When the lifting hook 7 is subjected to an upward pulling force, the lifting hook 7 can drive the cylinder 5 to move downward. The cylinder 5 can now squeeze the spring 6, and the spring 6 is compressed. At the same time, the cylinder 5 drives the lifting hook 7 to move downward, and the annular frame 8 moves upward relative to the lifting hook 7. The annular frame 8 can now extend upward, and the annular frame 8 can block the notch above the lifting hook 7. In this way, during the process of lifting the cable, the probability of the cable falling off the lifting hook 7 can be reduced. A card block 9 is fixedly installed on the inner side of the annular frame 8, and the card block 9 can block the cable to further prevent the cable from falling off. The material of the card block 9 is austenitic stainless steel, and the card block 9 made of austenitic stainless steel has higher strength.

[0027] Embodiment 2

[0028] See also Figure 3-5A protective mechanism is provided on the inner side of the lifting hook 7, and the protective mechanism includes a circular hole 12, and the circular hole 12 is opened on the inner side of the lifting hook 7. A gasket 13 is fixedly installed on the inner wall of the circular hole 12, and a round block 14 is provided inside the circular hole 12. A protective sheet 15 is fixedly installed on the top of the round block 14. The material of the protective sheet 15 is natural rubber. By setting the protective sheet 15, since the material of the protective sheet 15 is natural rubber, it is relatively soft, so that when the cable is hoisted, the lifting hook 7 can be prevented from being directly hard with the cable. The cable is worn due to sexual contact. The shape of the protective sheet 15 is the same as that of the lifting hook 7. The protective sheet 15 is pulled outward, and the protective sheet 15 then drives the round block 14 to escape from the round hole 12. At this time, the protective sheet 15 can be removed. When installing the protective sheet 15, it is only necessary to align the round block 14 under the protective sheet 15 with the round hole 12 and insert it. After the round block 14 is squeezed into the round hole 12, the friction force applied by the gasket 13 can fix the protective sheet 15, which makes it convenient to replace and maintain the protective sheet 15.

[0029] Working principle: the cable is wound into a circle, and when hoisting, the cable circle is hung on the hoisting hook 7, and then the electric hoist 2 drives the hanging rope chain 3 to move, and the hanging rope chain 3 subsequently drives the hoisting hook 7 to move. The hoisting hook 7 can now lift the cable to hoist the cable, and when the hoisting hook 7 is subjected to an upward pulling force, the hoisting hook 7 can drive the cylinder 5 to move downward, and the cylinder 5 can squeeze the spring 6 at this time. At this time, the spring 6 is compressed, and at the same time, the cylinder 5 drives the hoisting hook 7 to move downward, and the annular frame 8 moves upward relative to the hoisting hook 7. The annular frame 8 can be extended upward at this time, and the annular frame 8 can block the gap above the hoisting hook 7. In this way, during the process of hoisting the cable, the probability of the cable falling off the hoisting hook 7 can be reduced. The utility model significantly reduces the cable during the hoisting process by introducing a mechanism for the annular frame 8 to block the gap above the hoisting hook 7. In order to reduce the risk of falling off, a protective sheet 15 is set up. Since the material of the protective sheet 15 is natural rubber, which is relatively soft, when the cable is hoisted, the direct hard contact between the hoisting hook 7 and the cable can be avoided to cause cable wear. When the protective sheet 15 is severely worn and needs to be replaced, the staff only needs to pull the protective sheet 15 outwards, and the protective sheet 15 then drives the round block 14 out of the round hole 12. At this time, the protective sheet 15 can be removed. When installing the protective sheet 15, it is only necessary to align the round block 14 under the protective sheet 15 with the round hole 12 and insert it. After the round block 14 is squeezed into the round hole 12, the friction force applied by the gasket 13 can fix the protective sheet 15, which has the effect of facilitating the replacement and maintenance of the protective sheet 15. The utility model can effectively reduce the hard wear caused by direct contact by adding a protective sheet 15 made of natural rubber between the hoisting hook 7 and the cable.
