Description

Technical Field

[0001] The invention relates to the technical field of cable use equipment, and in particular to a cable lifting device. Background Art

[0002] Cables are usually made of several or several groups of wires twisted together into a rope-like structure. Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. They are often erected in the air or installed underground or underwater for telecommunications or power transmission. When cables are in use, multiple cables are installed together in a cable trench. Sometimes the cables are intricate and entangled with each other. If a single cable needs to be lifted, it is usually lifted with a crowbar and then a rope is inserted to lift it. When prying the cable, the leverage point is on the outer skin of the nearby cable, which can easily cause irreversible damage to the nearby cables. In addition, it is difficult to lift with a crowbar, which requires a lot of effort and wastes manpower. Summary of the invention

[0003] Based on this, it is necessary for the present invention to provide a cable lifting device that does not cause damage to the cable and saves manpower.

[0004] In order to achieve the purpose of the present invention, the present invention adopts the following technical solutions:

[0005] A cable lifting device, comprising:

[0007] A cable hooking component, the cable hooking component is connected to the fixing component, the cable hooking component comprises an outer hook clamp and an inner hook clamp, the outer hook clamp is provided with an inner cavity, and the inner hook clamp is slidably mounted in the inner cavity; and

[0008] A driving component is connected to the inner hook clamp. When the driving component is in motion, the inner hook clamp is driven to slide along the outer hook clamp to extend out of the outer hook clamp.

[0009] The above-mentioned cable lifting device first positions the outer hook clamp at a single cable, and then drives the inner hook clamp to extend through the driver to clamp the single cable, thereby completing the lifting of the cable. Since the outer hook clamp and the inner hook clamp only contact the adjacent cables during the process, they will not cause damage to the adjacent cables; and in the process, the inner hook clamp is under the action of the driving component, and human strength acts on the driving component. Compared with the existing cable prying method, the force used is greatly reduced, saving manpower.

[0010] In some embodiments, the outer hook clamp and the inner hook clamp are both arc-shaped, and at least one end of the outer hook clamp is provided with an extension port connected to the inner cavity. When the driving component is activated, the inner hook clamp is driven to slide along the outer hook clamp so as to extend out of the outer hook clamp from the extension port.

[0011] In some embodiments, the outer hook clamp and the inner hook clamp are both semicircular in shape.

[0012] In some embodiments, two ends of the outer hook clamp are respectively provided with a protruding opening.

[0013] In some embodiments, the driving component includes a pushing member, and the pushing member is connected to the inner hook clamp. When the pushing member is pushed, the inner hook clamp extends out of the outer hook clamp.

[0014] In some embodiments, the driving component further includes a moving member connected to the pushing member, and when the moving member moves, the pushing member is driven to push the inner hook forceps.

[0015] In some embodiments, the pushing member includes a first gear connected to the moving member and a second gear meshing with the first gear, the second gear extends into the outer hook clamp and is connected to the inner hook clamp, when the moving member moves, the first gear is driven to rotate, and the second gear rotates to push the inner hook clamp.

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] Embodiment 1

[0029] Please refer to Figures 1 to 3 The present invention provides a cable lifting device 100 for lifting a single cable from a plurality of cable installation positions, which includes a fixing component 10, a cable hooking component 20 connected to the fixing component 10, and a driving component 30. Figure 1 The cable hooking component 20 includes an outer hook clamp 21 and an inner hook clamp 22. The outer hook clamp 21 has an inner cavity 23, and the inner hook clamp 22 is slidably installed in the inner cavity 23; the driving component 30 is connected to the inner hook clamp 22. When the driving component 30 is activated, the inner hook clamp 22 is driven to slide along the outer hook clamp 21 to extend out of the outer hook clamp 21.

[0030] When in use, a person holds the fixing component 10 by hand, positions the cable hooking component 20 to the cable to be lifted, and actuates the driving component 30 so that the inner hook clamp 22 extends out of the outer hook clamp 21 and hooks the cable, and moves the entire lifting device 100 to lift the cable.

[0031] In one embodiment, the fixing component 10 includes a fixing rod 11, and the cable hooking component 20 is connected to the end of the fixing rod 11. A person can hold the fixing rod to move the position of the cable hooking component 20 to position the cable hooking component 20 at the cable. Of course, the fixing component 10 can also include a fixing block, a fixing cylinder and other components, which can achieve the purpose of connecting the cable hooking component 20 and is convenient for human hands to hold.

[0032] In one embodiment, the fixing member 10 further includes a clamping handle 12, which is mounted on the end of the fixing rod 11 away from the cable hooking member 20. A person can hold the clamping handle 12 to move the fixing rod 11, which makes it easier to hold the fixing rod 11 and prevent it from slipping.

[0033] Please continue to refer to Figure 1 In one embodiment, both the outer hook clamp 21 and the inner hook clamp 22 are in an arc shape, and at least one end of the outer hook clamp 21 is provided with an extension port 24 communicating with the inner cavity 12. When the driving component 30 is actuated, the inner hook clamp 22 is driven to slide along the outer hook clamp 21 so as to extend out of the outer hook clamp 21 through the extension port 24. For example, both the outer hook clamp 21 and the inner hook clamp 22 are in a semicircular shape. When the inner hook clamp 22 is extended to the limit, it can form a circle together with the outer hook clamp 21.

[0034] In one embodiment, the two ends of the outer hook pliers 21 are respectively provided with the above-mentioned extension openings 24. At this time, the inner hook pliers 22 can be extended from any extension opening 24 to achieve the purpose. When the driving component 30 is driven forward and reversely, the inner hook pliers 22 are driven to extend toward the extension openings 24 in different directions respectively. The driving direction of the driving component 30 can be selected according to actual conditions.

[0035] Of course, the outer hook 21 and the inner hook 22 may also be in other shapes such as hooks, as long as the inner hook 22 can hook the cable, and the inner hook 22 extends from the outer hook 21 at the end of the outer hook 21. When the inner hook 22 is in a hook shape, it extends from one of the extension ports 24.

[0036] The inner hook clamp 22 can also extend from a non-end position of the outer hook clamp 21. As long as the structure can allow the inner hook clamp 22 to extend and hook the cable, the location of the extension opening 24 and the extension position of the inner hook clamp 22 are not limited.

[0037] The degree to which the inner hook clamp 22 extends is determined according to the on-site needs, and the inner hook clamp 22 can hook the cable and pull the cable out. Of course, the inner hook clamp 22 can also extend to the limit.

[0038] Please refer to Figure 4 In one embodiment, the driving member 30 includes a pusher 31, which is connected to the inner hook pliers 22. When the pusher 31 is pushed, the inner hook pliers 22 extends out of the outer hook pliers 21. The pusher 31 can be pushed by hand, or by a component connected to the pusher 31.

[0039] In one embodiment, the driving member 30 further comprises a moving member 32 connected to the pushing member 31. When the moving member 32 moves, the pushing member 31 is driven to push the inner hook pliers 22. Compared with directly pushing by hand, the moving member 32 connected to the pushing member 31 saves a lot of effort.

[0040] In one embodiment, the pushing member 31a includes a first gear 33 connected to the moving member 32 and a second gear 34 meshing with the first gear 33. The second gear 34 extends into the outer hook clamp 21 and is connected to the inner hook clamp 22. When the moving member 32 moves, the first gear 33 is driven to rotate, and the first gear 33 drives the second gear 34 to rotate. When the second gear 34 rotates, it pushes the inner hook clamp 22 to extend.

[0041] The first gear 33 is installed in the outer hook clamp 21 , and the second gear 34 can be installed in the outer hook clamp 21 , or can be installed outside the outer hook clamp 21 and extend into the outer hook clamp 21 to connect with the first gear 33 .

[0042] When the pushing member 31 is not connected to the moving member 32 , it may be a pushing member such as a cylinder or a hydraulic cylinder.

[0043] Please refer to Figure 1 In one embodiment, the moving member 32 includes a rotating rod 35. A person holds the rotating rod 35 and rotates the rotating rod 35, so that the second gear 34 connected to the rotating rod 35 rotates.

[0044] Furthermore, the moving member 32 further includes a rotating handle 36 mounted on an end of the rotating rod 35 away from the second gear 34. A person holds the rotating handle 36 to rotate the rotating rod 35 to prevent slipping.

[0045] In other embodiments, the driving component 30 can also be a driving arm installed on the outer hook clamp 21, which is connected to the inner hook clamp 22. A sliding cavity is opened on the outer hook clamp 21. When the driving arm moves along the sliding cavity, it can push the inner hook clamp 22 to move, which is similar to the structure of the original bicycle lock.

[0046] The above-mentioned cable lifting device first positions the outer hook clamp at a single cable, and then drives the inner hook clamp to extend through the driver to clamp the single cable, thereby completing the lifting of the cable. Since the outer hook clamp and the inner hook clamp only contact the adjacent cables during the process, they will not cause damage to the adjacent cables; and in the process, the inner hook clamp is under the action of the driving component, and human strength acts on the driving component. Compared with the existing cable prying method, the force used is greatly reduced, saving manpower.

[0047] Embodiment 2

[0048] Please refer to Figure 5 The cable lifting device described in this embodiment is basically the same as that in the first embodiment, except that the driving component 30b includes a moving member 32 and a pushing member 31b, the pushing member 31b also includes a rotating wheel 37 connected to the first gear 33, and the moving member 32 is connected to the rotating wheel 37. The moving member 32 drives the rotating wheel 37 to rotate, and the rotating wheel 37 drives the first gear 33 to rotate, thereby realizing the rotation of the second gear 34. The use of the rotating wheel 37 can more conveniently rotate the first gear 33.

[0049] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
