More specifically, the structural frames and effects exerted by the first side frame 11 and the second side frame 12 of the main frame 1 are the same in the present embodiment. In order to enable the lifting platform 3 to slide up and down on the main frame 1 smoothly, the first side frame 11 and the second side frame 12 are arranged relatively in parallel, and a groove track 13 for providing the lifting platform 3 to slide is further arranged on the main frame 1, wherein the groove track 13 is arranged along the height direction of the first side frame 11 and the second side frame 12. The groove track 13 is disposed on the side of the end portion of the first side frame 11 and the second side frame 12 close to the lifting platform 3.

In this embodiment, the lifting platform 3 is provided with a first lifting hook 31 and a second lifting hook 32, the first lifting hook 31 is slidably connected to the first side frame 11, and the second lifting hook 32 is slidably connected to the second side frame 12. In order to ensure that the lifting platform 3 can support cables well, the first lifting hook 31 and the second lifting hook 32 are arranged relatively parallel. For unfolding, the first lifting hook 31 and the second lifting hook 32 are respectively provided with a lifting part 311 for supporting cables. (since the characteristics and effects of the lifting portions on the first lifting hook 31 and the second lifting hook 32 are the same, only the lifting portion 311 of the first lifting hook 31 is taken as an example for illustration here), the lifting portion 311 has a hemispherical shape with a concave middle portion and slightly higher sides to attach to the outer side surface of the cable, and the cable can be prevented from falling from the lifting portion 311. Further, the lifting portion 311 is further provided with a first roller 3111 and a second roller 3112 for reducing friction between the cable and the lifting hook. The first roller 3111 and the second roller 3112 are disposed on two sides of the wall surface of the lifting portion 311, and a rolling direction of the first roller 3111 and the second roller 3112 is perpendicular to a sliding direction of the lifting table 3.

It should be noted that, in the present embodiment, the structural design and the effect of the first roller 3111 and the second roller 3112 on the first lifting hook 31 and the second lifting hook 32 are the same, and thus, in the present embodiment, the first roller 3111 and the second roller 3112 of the lifting portion 311 on the first lifting hook 31 are specifically described as examples. And thus the first roller and the second roller on the second lifting hook 32 will not be described in detail. The driving device 2 is preferably a lithium battery direct current motor, the driving device 2 is arranged at the bottom of the main frame 1, and the driving device 2 is connected with the lifting table 3. The driving device 2 drives the two lifting hooks of the lifting platform 3, the two lifting hooks support the cable to synchronously ascend or descend, and the position height of the two lifting hooks is regulated and controlled according to the wish of a user.

The main frame 1 is further provided with a cross bar 14, and the cross bar 14 is rotatably connected with the first side frame 11 and the second side frame 12. The cross bar 14 is disposed in the gap between the first side frame 11 and the second side frame 12. In detail, the cross bar 14 includes a damping shaft, and the damping shaft is located in the inner cavity of the cross bar 14 and is disposed at the end of the cross bar 14 near the first side frame 11 and the second side frame 12. The damping shaft is used to limit the angle of rotation of the cross bar 14. Then, the cross bar 14 can rotate by matching the damping rotating shaft with the first side frame 11 and the second side frame 12, and has a rotation degree of freedom.

It is emphasized that in this embodiment the cable lifter further comprises a support assembly 4. The support assembly 4 is intended to abut against an external structure, such as a wall of a cable rack. The cable lifter is prevented from tilting or shaking. The support assembly 4 is fixedly connected with the cross bar 14, and the support assembly 4 rotates along with the cross bar 14, so that the position of the support assembly 4 relative to the main frame 1 changes. The support assembly 4 comprises a main support bar 41 and a secondary support bar 42; the main supporting rod 41 is fixedly connected with the cross rod 14 near one end of the cross rod 14, and an included angle formed by the main supporting rod 41 and the cross rod 14 is 90 degrees. The auxiliary supporting rod 42 is sleeved in the inner cavity of the main supporting rod 41, and the main supporting rod 41 is movably connected with the auxiliary supporting rod 42. In more detail, the outer wall surface of the auxiliary supporting rod 42 is provided with a screw thread for rotation, and can be extended and contracted in cooperation with the main supporting rod 41. The auxiliary supporting bar 42 may be rotated out of or retracted into the inside of the main supporting bar 41 by manual operation of a user. The secondary support bar 42 is subject to an external force to change between a first position and a second position relative to the primary support bar 41; when the auxiliary supporting rod 42 is positioned at the first position, the auxiliary supporting rod 42 is accommodated in the main supporting rod 41; the auxiliary supporting rod 42 is exposed outside the main supporting rod 41 when the auxiliary supporting rod 42 is located at the second position. The auxiliary supporting rod 42 includes an abutment 421 for abutting against an external structure, and the abutment 421 is disposed at an end of the auxiliary supporting rod 42 away from the cross rod 14.

Further, the key steps of the cable lifter are specifically described herein. In this embodiment, a cable rack commonly used in factories is described as an example. First, the cable lifter is ready to work before being lifted, and a user firstly regulates and controls the supporting component 4 of the cable lifter, so that the supporting component 4 can be directly abutted to the wall surface of the cable frame to prevent the cable lifter from losing balance. In detail, the cross bar 14 is rotated first to make the main supporting rod 41 of the supporting assembly 4 horizontally aligned with the wall surface of the cable rack, and then the auxiliary supporting rod 42 inside the main supporting rod 41 is rotated out from inside to outside through threads, so that after the auxiliary supporting rod 42 is extended, the abutting joint 421 mounted at the end of the auxiliary supporting rod 42 is ensured to be fully abutted against the wall surface of the cable rack. Then, the user places the cable lifter in the operation region of the cable rack and places the cable lifter at equal distances. Preferably, each cable lifter is disposed at a spacing of 2 m. The user then carries the cable to the lift table 3 of the cable lifter. After the preparation work of the cable lifting is completed, when the cable lifter is lifted, it should be noted that the cable lifter placed in the middle of the cable rack operation section sequentially lifts the cable to a specified certain height toward the cable lifters placed at both sides of the cable rack operation section, and it can be understood that the cable lifter in the middle needs to lift the cable in advance when the cable is lifted, and then sequentially lifts the cable toward both sides. The middle part is earlier both sides slightly slow, and so operation aim at lets two cable lifters of adjacent interval can get up by complete utilization, also can prevent to make the cable lifter topples over to one side because of the focus is unstable when lifting the cable. Subsequently, the driving device 2 is started to drive the first lifting hook 31 and the second lifting hook 32 of the lifting platform 3 to slide from low to high, and the two lifting hooks synchronously move. At this time, a plurality of cable lifters work simultaneously, and the cable lifter placed at the last side of the cable rack operation section can properly reduce the lifting height according to the deflection generated by the lifting height, so as to avoid the deflection damage of the cable caused by overhigh lifting. When the cable is lifted to the designated uniform height, the cable on the lifting part 311 is pushed into the cable rack directly by a person.

The foregoing is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto, and any person skilled in the art will be able to make insubstantial modifications of the present utility model within the scope of the present utility model disclosed herein by this concept, which falls within the actions of invading the protection scope of the present utility model.
