Description

Technical Field

[0001] This utility model belongs to the technical field of cable fixing devices, specifically relating to a tower crane cable fixing device. Background Technology

[0002] Tower cranes are a common type of lifting equipment on construction sites. A tower crane consists of an electrical system, a metal structure, a working mechanism, and a mounting device. The electrical system consists of a motor, a controller, a distribution box, and cables. The cables are generally fixed to the tower crane's upper pole and tubular steel structure using cable clamps. The vertical cables are clamped by the corresponding clamping components, thereby securing the cables.

[0003] During the process of clamping and fixing cables, the vibration and swaying of the tower crane can cause vertical cables to loosen and slip off from their relatively clamped state, resulting in cable instability and swaying. This can lead to friction and damage between the cable and other parts of the tower crane. The cable fixing clamps, which hold vertical cables, are prone to slipping and falling. The design cannot bend the clamping part of the cable to increase friction and prevent the cable from slipping off, which is a shortcoming.

[0004] Existing cable fixing designs for tower cranes lack the ability to bend and clamp the cable. To address this, this application proposes a tower crane cable fixing device. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a tower crane cable fixing device, including a fixing seat 1 installed on the tower crane rod. Figure 1 In this context, A represents the tower crane rod on the tower crane frame. Figure 1 In this diagram, B represents the cable. The mounting base 1 is fixed to the tower crane rod A by the first bolt 11. The cable clamping assembly includes a mounting plate 2 welded to the mounting base 1, a protrusion 3 welded to the mounting plate 2, a mounting frame 4 assembled with the mounting plate 2, a second bolt 41 penetrating the mounting frame 4 and the protrusion 3, and a clamping component mounted on the side of the mounting frame 4. The mounting frame 4 and the mounting plate 2 are a combined structure that can clamp the cable B. When the mounting frame 4 and the mounting plate 2 are in contact, the mounting frame 4 and the protrusion 3 are fixed by the second bolt 41. The clamping component includes a fixing post 6 perpendicular to the mounting frame 4, an extrusion plate 7 welded to one end of the fixing post 6, and a protrusion 71 mounted on the inner surface of the extrusion plate 7. A limiting block 21 is provided on the top surface of the mounting plate 2. The plate 2 is provided with a cable groove 22. When the mounting frame 4 and the mounting plate 2 fix the cable B, the extrusion plate 7 restricts the cable B, and the protrusion 71 abuts against the cable B, so that the cable B presents an arc-shaped bending shape between the mounting plate 2 and the extrusion plate 7. The bending angle of the cable groove 22 and the protrusion 71 in the mounting plate 2 matches the bending angle of the cable B, increasing the friction between the mounting plate 2 and the extrusion plate 7 and preventing the cable B from loosening and slipping due to vibration. The collar pad 8 is sleeved on the outside of the cable. The outer surface of the collar pad 8 is provided with symmetrically distributed connecting blocks 81. The connecting blocks 81 are penetrated by a third bolt 82. The collar pad 8 is fixed by the third bolt 82. The limiting block 21 abuts against the collar pad 8, thereby reinforcing the cable B.

[0026] In this embodiment, the cross-section of the fixing seat 1 is a "U" shaped structure, and the first bolt 11 passes through the fixing seat 1 to facilitate the installation of the fixing seat 1 on the tower crane rod A.

[0027] In this embodiment, the mounting plate 2 has a recessed movable groove on the surface facing the mounting frame 4. The cable groove 22 is connected to the movable groove. The cable groove 22 is arc-shaped. The mounting frame 4 is a frame structure. The extrusion plate 7 is a "U"-shaped structure. The protrusion 71 is arch-shaped. The inner surface of the cable groove 22 matches the curve angle of the cable B in its bent state, so that the cable B is held by the protrusion 71 in the cable groove 22.

[0028] In this embodiment, the collar pad 8 is a frustum structure with one end wide and the other end narrow, and the cross-section of the collar pad 8 is an open ring shape. The connecting block 81 is connected to the open end of the collar pad 8, which makes it easy to put the open collar pad 8 on the outside of the cable B. The third bolt 82 fixes the connecting block 81, thereby fixing the collar pad 8 to the cable B.

[0029] In this embodiment, a diagonal brace 5 is welded to the top surface of the mounting frame 4. The inclined top of the diagonal brace 5, which is in an inclined state, is in contact with the outer surface of the collar pad 8. A recessed groove is provided on the limiting block 21. A connecting rod 51 is welded to the diagonal brace 5. One end of the connecting rod 51 is provided with an arc-shaped support pad 52. The diagonal brace 5 and the support pad 52 abut against the collar pad 8, thereby reinforcing the cable B with diagonal bracing and preventing the cable B from slipping down.

[0030] Working principle and usage process of this utility model:

[0031] When fixing cable B, the fixing seat 1 is fixed to the tower crane rod A by the first bolt 11;

[0032] Cable B is placed inside mounting plate 2, mounting frame 4 is combined with mounting plate 2, and mounting frame 4 and protrusion 3 are locked by second bolt 41;

[0033] The extrusion plate 7 restricts the cable B, and the protrusion 71 abuts against the cable B, so that the cable B presents an arc-shaped bending shape between the mounting plate 2 and the extrusion plate 7. The bending angle of the cable groove 22 in the mounting plate 2 and the protrusion 71 matches the bending angle of the cable B, increasing the friction between the mounting plate 2 and the extrusion plate 7, and preventing the cable B from loosening and slipping due to vibration.

[0034] The collar gasket 8 is fixed by the third bolt 82, and the limiting block 21 abuts against the collar gasket 8, thereby limiting and fixing the cable B.

[0035] The diagonal bracing plate 5 and the support pad 52 abut against the collar pad 8, thereby reinforcing the cable B with diagonal bracing and preventing the cable B from slipping downwards;

[0036] In summary, this application provides a fixed design for clamping and bending cables. The compression plate 7 restricts the cable B, the protrusion 71 abuts against the cable B, so that the cable B is clamped between the mounting plate 2 and the compression plate 7. The collar pad 8 fixes the cable, the limiting block 21 abuts against the collar pad 8, and the diagonal brace plate 5 and the support pad plate 52 abut against the collar pad 8, so that the cable B is reinforced by diagonal bracing and the cable B is prevented from sliding down and slipping.

[0037] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
