[0001] The utility model belongs to the technical field of cable tensioning, in particular to a cable erection tensioning machine. Background Art

[0002] A cable is a device for transmitting electric energy or signals, which is usually composed of several or several groups of wires. When installing the cable, the cable between the front end bracket and the rear end bracket of the cable is usually not tightened, and most of the time a slight curvature is reserved. At this time, the cable will shake when affected by wind factors, which can easily affect the service life of the cable. In order to reduce the shaking of the cable, a corresponding tensioning device is required to tension the cable.

[0003] The current tensioning device can tension the cable well, and it is mainly equipped with a tensioning housing, a guide roller, a tensioning roller, a lifting assembly, a line inlet, a line outlet and other components. Specifically, the cable is passed through the line inlet and the line outlet in sequence, and the cable is guided to the bottom of the tensioning roller by the guide roller. Then the lifting assembly adjusts the height of the tensioning roller as needed to tension the cable to reduce the shaking of the cable. However, impurities attached to the outer surface of the cable during the winding process will accumulate on the tensioning roller, which may cause the device to get stuck and affect the service life of the device.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] The embodiment of the utility model provides a cable installation tensioning machine, which solves the problem that the current tensioning device in the prior art can better tension the cable. The utility model mainly comprises a tensioning machine housing, a guide roller, a tensioning roller, a lifting assembly, a line inlet, a line outlet and other components. Specifically, the cable is passed through the line inlet and the line outlet in sequence, and the cable is guided to the bottom of the tensioning roller through the guide roller. Then, the lifting assembly adjusts the height of the tensioning roller as needed to tension the cable, so as to reduce the shaking of the cable. However, impurities attached to the outer peripheral surface of the cable during the winding process will accumulate on the tensioning roller, guiding The device may get stuck, which will affect the service life of the device. By setting a bracket on the fixed base plate and a reel rotatably set on the bracket, the staff can move the device to a suitable position when using the device, pass the cable through the cleaning ring and reel of the device, and when the cable needs to be tensioned, the staff rotates the reel through the adjusting wheel, and the reel reels and tensions the cable.
