Description

Technical Field

[0001] This utility model belongs to the field of crane technology, specifically a disk cable fixing structure for cranes. Background Technology

[0002] In existing sheet metal slitting processes, traditional processing plants often use felt tensioning devices for strip steel conveying and tension control. This method achieves material conveying and pressure stabilization through friction between the felt and the material surface. However, in practical applications, when the felt is in direct contact with the material surface, it inevitably absorbs and carries away some of the anti-rust oil film from the raw material surface, resulting in oil stains adhering to the galvanized steel sheet.

[0003] Chinese utility model patent CN209411577U discloses a quick-connect crane disk crane, including a crane and an electric disk. A fixing rod is fixedly connected to the outer surface of the crane hook pulley housing. The crane cable runs down along the hook and is wound around the fixing rod, with a female connector of a cable plug connected to its end. A support plate is fixedly connected to the outer end of the fixing rod. The female connector of the cable plug is bolted to the support plate via a mounting plate. A section of cable is connected to the electric disk, with a male connector of a cable plug at its end. When the electric disk is hooked onto the hook, the male and female connectors of the cable plug are inserted. This utility model uses a quick-connect device, requiring only two to three minutes for each electric disk assembly and disassembly operation, greatly reducing assembly and disassembly time and improving crane operating efficiency. Furthermore, when the cable on the electric disk wears out or breaks, it can be replaced individually, saving cable costs. The operation is very effective and can be promoted to other electric disk cranes.

[0004] However, the main method of fixing the disk cable is to fix it to the outside of the hook through male and female connectors and fixing rods. However, this fixing method completely locks the cable fixing point, causing the cable stress to be concentrated at one point, which can easily cause the cable sheath to be torn. In addition, the shaking of the crane hook may cause the disk cable to fall off at the fixing point. After long-term use, the cable diameter will be thinned due to stress, which will lead to the cable loosening or even breaking. Utility Model Content

[0005] The purpose of this utility model is to provide a disk cable fixing structure for cranes, so as to solve at least one aspect of the problems and defects mentioned in the background art.

[0006] A crane disk cable fixing structure is provided, including an electric disk, a crane hook connected above the electric disk by a plurality of disk chains, a disk cable being provided between the hook head tube seat and the electric disk, and a hook head tube seat being connected to the upper side of the disk cable by a flexible connection assembly.

[0007] Furthermore, the disk drive is provided with a junction box, the junction box is provided with a disk cable, the hook tube seat is provided with a U-shaped tube clamp seat, the disk cable is provided between the junction box and the U-shaped tube clamp seat, the U-shaped tube clamp seat is fixed on the hook tube seat, the hook tube seat mechanically clamps the disk cable and stabilizes its direction, so that the disk cable connection point is hardly subjected to tension, thus preventing the disk cable from being pulled off and damaged.

[0008] Furthermore, the U-shaped tube clamp is provided with a bayonet, and the disk cable is clamped inside the bayonet. If the flexible connection component breaks or fails due to aging or damage, the cable will slide down, but it will be clamped by the bayonet structure of the U-shaped tube clamp on the hook tube seat, preventing the disk cable from continuing to fall or being pulled out.

[0009] Furthermore, the U-shaped pipe clamp seat is detachably connected to the hook pipe seat, which facilitates the disassembly and replacement of the U-shaped pipe clamp seat.

[0010] Furthermore, the flexible connection assembly includes a wire rope retainer, which is snapped onto the upper side of the disk cable. The wire rope retainer is provided with a first retaining ring seat, and the upper side of the hook tube seat is provided with a second retaining ring seat. A galvanized steel wire rope is provided between the first retaining ring seat and the second retaining ring seat. Under normal operating conditions, the galvanized steel wire rope is in a slightly taut state, forming a downward pulling force on the disk cable, pulling the disk cable into a small bow shape. This transfers the stress point of the disk cable from the originally concentrated connection end to the connection point between the wire rope retainer and the galvanized steel wire rope, thereby buffering the pulling force and transferring the stress point, significantly reducing the risk of damage and detachment of the disk cable sheath.

[0011] Furthermore, both the first and second circlip seats are provided with mounting holes for installing galvanized steel wire ropes, providing installation connection points for the galvanized steel wire ropes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The flexible connector causes the disk cable to form a small downward bend at the top; the main stress point of the disk cable is guided and transferred to the contact point between the flexible connector and the hook tube seat. At this time, the actual load-bearing capacity of the lower end of the disk cable is mainly borne by the flexible connector, avoiding the disk cable from bearing pressure directly at the female end fixing point, effectively reducing the fatigue and wear of the disk cable, and improving safety compared to the single-point fixing method.

[0014] If the flexible connection component breaks or fails due to aging or damage, the cable will slide down, but it will be caught by the hook-shaped tube seat structure. This prevents the disk cable from continuing to fall or being pulled off, achieving a passive protection mechanism. Compared with the original structure, which is fixed by male and female connectors and fixing rods, the cable's stress points are concentrated and cannot be adjusted. Under frequent shaking or long-term pulling, it is prone to wear and breakage. The improved structure releases tension elastically through the flexible connection component, reducing the risk of cable breakage. At the same time, the risk of the cable falling off due to hook shaking is also greatly reduced. Attached Figure Description

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-3 As shown in the present invention, a crane disk cable fixing structure includes a disk 1, a crane hook 3 connected above the disk 1 by a plurality of disk chains 2, a hook head tube seat 4 provided on the crane hook 3, a disk cable 5 provided between the hook head tube seat 4 and the disk 1, and a hook head tube seat 4 connected to the upper side of the disk cable 5 by a flexible connection component 6. The flexible connection component 6 is a flexible connection structure provided between the upper end of the disk cable 5 and the hook head tube seat 4.

[0027] The flexible connector 6 causes the disk cable 5 to form a small downward-curving arc at the top. The main stress point of the disk cable 5 is guided and transferred to the contact point between the flexible connector 6 and the hook tube seat 4. At this time, the actual load-bearing capacity of the lower end of the disk cable 5 is mainly borne by the flexible connector 6, avoiding direct pressure on the disk cable 5 at the female end fixing point, effectively reducing fatigue and wear of the disk cable 5. If the flexible connector 6 breaks due to aging or damage, the cable will slide down, but it will be stuck by the hook tube seat 4 structure, preventing the disk cable 5 from continuing to fall or being pulled off, thus realizing a passive protection mechanism. Compared with the single-point fixing method, it improves safety. Compared with the original structure, which is fixed by male end connectors, female end connectors and fixing rods, the cable stress point is concentrated and cannot be adjusted. Under frequent shaking or long-term pulling, it is easy to wear and break. The improved structure releases the tension elastically through the flexible connector 6, reducing the risk of cable damage. At the same time, the risk of the cable falling off due to hook shaking is also greatly reduced.

[0028] In one embodiment, see Figure 1 and Figure 2 As shown, a junction box 11 is provided on the disk 1, a disk cable 5 is provided on the junction box 11, a U-shaped pipe clamp seat 7 is provided on the hook pipe seat 4, and the disk cable 5 is provided between the junction box 11 and the U-shaped pipe clamp seat 7. The hook pipe seat 4 is used to fix the direction of the disk cable 5 and the U-shaped pipe clamp seat 7. The U-shaped pipe clamp seat 7 is installed on the hook pipe seat 4 for mechanically clamping and fixing the disk cable 5, preventing the disk cable 5 from being damaged by stress due to gravity or shaking.

[0029] After the disk cable 5 is led out from the junction box 11, it is transmitted to the upper structure after a certain length. Since the disk cable 5 has weight and moves with the crane hook 3 (such as swaying or rotating), its root is easily subjected to repeated pulling, causing stress concentration at the connection. The U-shaped tube clamp 7 is fixed on the hook tube seat 4. The hook tube seat 4 mechanically clamps the disk cable 5 and stabilizes its direction, so that the connection point of the disk cable 5 is hardly subjected to tension, thus preventing the disk cable 5 from being pulled off and damaged.

[0030] In one embodiment, see Figure 1 and Figure 3 As shown, the U-shaped tube clamp seat 7 is provided with a bayonet 71, and the disk cable 5 is clamped inside the bayonet 71. The bayonet 71 is used to clamp the upper side of the disk cable 5 to achieve mechanical clamping and fixing. If the flexible connection component 6 breaks and fails due to aging or damage, the cable will slide down, but it will be clamped by the bayonet 71 structure of the U-shaped tube clamp seat 7 on the hook tube seat 4; preventing the disk cable 5 from continuing to fall or being pulled off.

[0031] In one embodiment, see Figure 1 and Figure 3As shown, a rubber pad 72 is provided inside the bayonet 71. The rubber pad 72 is made of materials such as EPDM rubber or silicone rubber, which serves to buffer and protect the outer sheath of the disk cable 5.

[0032] In one embodiment, see Figure 2 and Figure 3 As shown, the U-shaped pipe clamp seat 7 is detachably connected to the hook pipe seat 4, which facilitates the disassembly and replacement of the U-shaped pipe clamp seat 7.

[0033] In one embodiment, see Figure 1 and Figure 2 As shown, the flexible connection assembly 6 includes a wire rope retainer 61, which is snapped onto one side of the upper part of the disk cable 5. A first circlip seat 62 is provided on the wire rope retainer 61, and a second circlip seat 63 is provided on one side of the upper part of the hook tube seat 4. A galvanized wire rope 64 is positioned between the first circlip seat 62 and the second circlip seat 63. The wire rope retainer 61 is snapped onto the upper part of the disk cable 5 at an appropriate position, and the bolts are tightened to ensure no slippage. The first circlip seat 62 is fixed to one side of the wire rope retainer 61 by screws, and the second circlip seat 63 is installed on the upper part of the hook tube seat 4. Structurally, a galvanized steel wire rope 64 is connected between the first retainer 62 and the second retainer 63, so that it is in a slightly tensile state, which realizes the stress transfer of the disk cable 5. Under normal working conditions, the galvanized steel wire rope 64 is in a slightly tensile state, forming a downward force on the disk cable 5, pulling the disk cable 5 into a small bow shape, so that the stress point of the disk cable 5 is transferred from the originally concentrated connection end to the connection point between the steel wire rope retainer 61 and the galvanized steel wire rope 64, thereby playing the role of buffering the tension and transferring the stress point, significantly reducing the risk of damage and detachment of the outer sheath of the disk cable 5;

[0034] The system reduces the stress impact on the disk cable 5 caused by the shaking of the hook tube seat 4. In the event of a breakage of the flexible connection, the U-shaped tube clamp seat 7 on the original hook tube seat 4 can still fix the disk cable 5, preventing the disk cable 5 from falling or being pulled off, thus providing redundant protection.

[0035] In one embodiment, see Figure 1 and Figure 2 As shown, both the first retaining ring seat 62 and the second retaining ring seat 63 are provided with mounting holes 8. The mounting holes 8 are used to install galvanized steel wire rope 64 and provide installation connection points for galvanized steel wire rope 64.

[0036] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
