Description

cable bender

technical field

The utility model relates to a cable bender, in particular to a cable bender suitable for 10kV high-altitude live working, and belongs to the field of electric tools.

Background technique

At present, there is no special cable bender for 10kV live work, and the insulating glove method is generally used to directly bend the cable. However, this method is very inconvenient to implement. Because the overhead power cable is a steel-cored aluminum stranded wire, which has high hardness, especially when the bent wire is relatively short, it is very difficult to implement, and because it is high-altitude live work, 10kV live work is added. The risk factor of personnel brings great inconvenience to work and seriously affects work efficiency.

Utility model content

According to the deficiencies of the prior art, the purpose of this utility model is to: provide a cable bender, which is convenient for high-altitude workers to operate, can greatly save the physical exertion of the workers during the cable bending process, improve bending flexibility, and improve liveliness. Improve operating efficiency and ensure the personal safety of live workers.

The cable bender described in the utility model includes a left sleeve and a right sleeve hinged by a rotating shaft, handles are respectively provided on the left sleeve and the right sleeve, and card wheels, Ratchet, the ratchet cooperates with the pawl installed on the convex plate of the right sleeve, the card wheel cooperates with the clamp rod, the end of the clamp rod is connected with the push button, the push button is installed on the square box, and the square box is fixed on the left sleeve.

When bending the cable, rotate the left sleeve and the right sleeve relative to each other. With the cooperation of the ratchet and pawl, it can only rotate in one direction and cannot be reversed, so as to prevent the bent cable from recovering under its own elastic force. , Workers can let go after bending the cable to the specified angle, no need to apply force all the time, easy to use, and greatly save the physical exertion of workers. Push the lever through the push button, and the lever will block the wheel and limit the rotation of the ratchet, so as to realize the above operation. When it needs to be reset, push the button backward, the lever will be separated from the wheel, and the ratchet will rotate under the action of the ratchet. Reset, practical, flexible and convenient.

A dial is fixed on the opposite side of the left sleeve to the handle, and the scale of the dial is 0-180°. The rotation angle can be read through the scale, so as to have a better grasp of the bending angle of the cable, especially for cables with specific bending angles. The required cables are positioned more accurately and work efficiency is improved.

The accuracy of the dial is 1°.

The diameter of the left sleeve is smaller than that of the right sleeve, and the end of the left sleeve is sleeved in the right sleeve and hinged by the rotating shafts on both sides.

The surface of the handle is provided with an insulating material layer to increase the safety factor.

When in use, pass the cable through the left sleeve and the right sleeve, push the push button forward, so that the clamping rod is stuck on the clamping wheel to prevent the ratchet from rotating, the operator grasps the handles on both sides, and bends hard to the middle , the dial rotates with the left sleeve, and the bending angle can be read through the dial. When bending, since the ratchet does not move, the pawl will be stuck on the ratchet at any time when it moves. Therefore, only one-way rotation can be performed to avoid bending after bending. After the cable is reset, after the bending is completed, push the push button back along the chute to separate the clamping rod from the clamping wheel, and rotate the left sleeve and the right sleeve to reset.

Compared with the prior art, the utility model has the beneficial effects of:

The cable bender has a simple structure and is easy to use, which can greatly save the physical exertion of workers during the cable bending process, improve bending flexibility, improve the efficiency of live work, and ensure the personal safety of live work workers.

Detailed ways

Embodiments of the utility model are further described below in conjunction with the accompanying drawings

As shown in Figures 1-2, the cable bender includes a left sleeve 2 and a right sleeve 5 hinged by a rotating shaft 4, the diameter of the left sleeve 2 is smaller than that of the right sleeve 5, and the end of the left sleeve 2 is sleeved on the right sleeve. The barrel 5 is hinged by two rotating shafts 4 respectively. The same side of the left sleeve 2 and the right sleeve 5 are respectively provided with a handle 1, and the surface of the handle 1 is provided with an insulating material layer to increase the safety factor. On the rotating shaft 4 on the same side as the handle 1, a card wheel 8 and a ratchet 9 are successively installed, and the ratchet 9 cooperates with the pawl 7 installed on the convex plate 6 of the right sleeve 5, and through the cooperation of the pawl 7 and the ratchet 9, the right Sleeve 5 can only do unidirectional rotation with respect to left sleeve 2, can not turn around. The card wheel 8 cooperates with the card rod 10, the end of the card rod 10 is connected with the push button 11, the push button 11 is installed on the square box 12, the square box 12 is fixed on the left sleeve 2, and the push button 11 is along the chute of the square box 12 13 settings, the card wheel 8 is a toothed wheel body, and the teeth can be square teeth or triangular teeth. When the clamping rod 10 was stuck on the clamping wheel 8, the ratchet 9 could not rotate, and now the bending operation could be carried out. When the clamping rod 10 was separated from the clamping wheel 8, the ratchet 9 could rotate and reset.

work process:

When in use, pass the cable through the left sleeve 2 and the right sleeve 5, push the push button 11 forward, make the clamping rod 10 stuck on the clamping wheel 8, prevent the ratchet 9 from rotating, and the operator grasps the handles on both sides 1. Bend hard in the middle, the dial 3 rotates with the left sleeve 2, read the bending angle through the dial 3, when bending, because the ratchet 9 does not move, the ratchet 7 is stuck on the ratchet 9 at any time when it moves, Therefore, only one-way rotation can be carried out to avoid the reset of the cable after bending. After the bending is completed, the push button 11 is pushed back along the chute 13 to separate the clamping rod 10 from the clamping wheel 8, and rotate the left sleeve 2 and Right sleeve 5 resets.
