Ground wire overhead vehicle special for large span

Abstract

The invention relates to a ground wire overhead vehicle special for a large span. The ground wire overhead vehicle is composed of bearing pulleys (1), a working platform (2), wire hanging pulleys (3), a rope containing device (4), a ground wire (5) and a pulling rope (6); the working platform (2) is installed at the right side; the rope containing device (4) is installed at the left side; two sets of bearing pulleys (1) are installed on the working platform (2); the working platform (2) and the rope containing device (4) are connected through the pulling rope (6); two sets of wire hanging pulleys (3) are installed over the pulling rope (6); and the ground wire (5) is installed over the working platform (2). The ground wire overhead vehicle special for the large span disclosed by the invention has the benefits that: the construction time is saved; the noise nuisance and environmental pollution problems due to usage of pulling and tensioning equipment can be reduced; all parts are installed in an overhead wire outgoing manner; and influence of construction on passage of the Yangtze river waterway is reduced.

Description

Technical field [0001] The present invention involves a widely used on -leaping and easy access to the overhead ground line to install the police, the damping line and the anti -vibration hammer, reduce the physical consumption of staff, improve the efficiency of work, and reduce the time of the sealing time.The safety of the person and the equipment is a large span of a special ground. Background technique [0002] With the continuous expansion of the power grid construction, large -capacity, long -distance cross -zone transmission and transformation projects have increased. For overhead transmission cables, especially high -voltage cables and cross -river cable transmission cables, the eye -catching aviation should be set on the lineSign the ball aviation warning ball to provide warning signs.Therefore, severe challenges have been put forward on the construction equipment, construction technology and technology of the large -scale cross -line police, and the construction equipm...

AI Technical Summary

Problems solved by technology

[0007] Use the ground wire to loosen and hang the accessories before installing the police navigation ball. Since the ground wire sag is 189.3m5°C, it is equivalent to a height difference of nearly 190m from the suspension point to the center of the gear distance. If such a large height difference is on the ground wire If the accessories are installed and then installed, it is necessary to carry 11 police nav
