Problems solved by technology

Therefore, after the wire tightening work is over, the staff has to use their shoulders to lift the wires out of the trolley, lift them up to the height of the insulator, and put them into the groove on the top of the insulator for binding. This requires a lot of physical strength and seriously affects the work. schedule
[0004] In the construction, the conductors with small diameters are relatively light, and the staff can complete the lifting and binding of the conductors without much effort. For the phase line, since the pay-off block must also be fixed on the lower cross arm, the distance from the insulator on the top of the pole is about 1100mm. The height distance is very large, and sometimes even two people are required to complete it, which will easily lead to slow construction progress and delay in power transmission time. status
The second disadvantage is that in order to reduce the difficulty of lifting the neutral phase line, the pay-off block is usually removed from the lower cross arm, and then fixed to the top cap of the neutral phase line for use. The problem caused by this is that it needs a second It is very inconvenient to disassemble and install the wire block
The third disadvantage is that after the wire is lifted to a higher insulator, the tension of ...

Abstract

The invention discloses an overhead line laying device for agricultural power transmission, which comprises a base, the bottom of which is provided with a lower locking device for locking and cooperating with the pole cross-arm, the base is fixed with a bracket, and the bracket is hinged with a support tube through the bracket shaft , the bracket is provided with a lower positioning device for positioning and matching the support cylinder, the upper end of the support cylinder is installed with an upper gear that rotates close to the outer surface of the main support plate through a rotating connection device, and the support cylinder is equipped with a gear that is snapped and positioned with the teeth of the upper gear In the upper positioning device, an upper bracket is hinged on the upper part of the upper gear, and an upper locking device is arranged between the auxiliary support plate and the upper bracket. The advantage is that it is easy to install, reliable to fix, and easy to disassemble. It can freely adjust the pay-off height according to the actual height of the pole insulator, and can automatically determine the length of the pay-off cable. It only needs to be installed and disassembled once when the wire is set up. After the wire tightening operation, it only needs to translate the wire. Yes, the tightness of the wires before and after the tightening is consistent to ensure the quality, and one person can operate it.

Description

technical field [0001] The invention relates to a laying device for agricultural power transmission overhead lines. Background technique [0002] The pay-off pulley is a tool that must be used in the construction of power lines. The main structure is composed of aluminum or nylon pulleys, frame fixing devices, hooks or U-shaped groove stabilization devices. The use of pulleys in the process of line erection and tightening can reduce the wire The friction resistance can prevent the strand damage of the wire and the damage of the insulation layer, and can improve the construction speed and reduce the power outage time. [0003] Now in the construction of power lines of 10kV and below, the pay-off pulley used is about 140mm from the U-shaped groove stabilization device to the top of the pulley, while the height of the P-15 rod insulator is about 240mm, and the P-20 rod insulator height is about 240mm. The height of the insulator is about 350mm, the pulley is short, the insulat...
