An electric maintenance station sliding chair that uses air pressure to maintain balance and prevent gravity

Abstract

The invention discloses an electric power overhaul standing type sliding chair using air pressure to maintain balance and prevent center-of-gravity shift. The standing type sliding chair structurallycomprises pulleys, a truss, a supporting frame, auxiliary rods, a detachable safety belt and a center-of-gravity shift prevention device; the pulleys are arranged on the inner side of the supporting frame and are connected with the supporting frame through a rotating mode, the truss is connected with the supporting frame through a welding mode, and the auxiliary rods are connected with the supporting frame. According to the electric power overhaul standing type sliding chair in the invention, through the acting force of a electromagnet to an armature, a connecting rod is used for driving clamping plates on the two sides to simultaneously inward or outward operate, a serviceman is fixed in a certain degree through the clamping plates, and the center of gravity of the serviceman is preventedfrom excessively shifting to one side of a seat plate to cause shaking; then, an air cavity is inflated through a valve port, so that a first ejector rod and a second ejector rod push the seat plateupwards along a sleeve; a universal ball moves in the seat plate, and the seat plate is basically kept horizontal until the numerical value of a gradienter is maintained within a certain range, such that the serviceman is enabled to keep a horizontal sitting posture, and operation and maintenance are convenient and labor-saving.

Description

technical field [0001] The invention relates to the field of electric power maintenance equipment, more precisely, it is an electric power maintenance station sliding chair which uses air pressure to maintain balance and prevent bias. Background technique [0002] In the process of rapid development of electric power, power system failures occur frequently, and the safety conditions and requirements for maintenance personnel in the process of electric power maintenance are becoming more and more stringent. At present, most of them use two-wheeled slide chairs for power maintenance to move, repair wires, Cable, the existing traditional technology is not comprehensive, has the following disadvantages: [0003] Due to the different heights of the wire and cable installation frames, the wires and cables are mostly inclined at a certain angle with the horizontal plane. The action of gravity will follow the tilt and slide of the double-wheel slide chair, and the shift of the cent...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an electric maintenance station sliding chair that uses air pressure to maintain balance and prevent bias, so as to solve the problem in the prior art that the wires and cables are installed at different heights, so that there are many wires and cables. Because there is a certain angle between the tilt and the horizontal plane, the maintenance personnel will sit on the sliding double-wheel slide chair on the fixed steel wire parallel to the wires and cables for maintenance. Due to the action of gravity, the double-wheel slide chair will follow the tilt and slide of the double-wheel slide chair, and the center of gravity will shift. Personnel need to allocate part of their energy to maintain balance, which reduces maintenance efficiency, and the maintenance personnel slide to the low end to make the force unbalanced on the double-wheeled slide chair, which is likely to cause damage to one side of the slide chair and cause accidents.
