Problems solved by technology

[0002] At present, it is difficult to conduct high-altitude test wiring for substation equipment maintenance and testing. For the wiring points that cannot be directly touched, operators need to climb up the equipment or use tower cranes and high-altitude buckets for wiring. Some equipment tower cranes

Embodiment Construction

[0008] With reference to accompanying drawing, when operating the present invention, rotating connector 15 makes it move by push-pull bar, steel wire rope and drives the upper pulley action of rotating bracket 4, and moving jaw approaches to fixed jaw thereupon, makes fixed and moving jaw clamp lead. The push-pull mechanism is equipped with a locking mechanism to ensure the clamping force of the jaws. The installation holes of the fixed and movable jaws are obliquely long, so that lateral frictional movement occurs while the jaws are clamped to overcome the oxide film at the wiring position. Thereby protecting the electrical conductivity.

[0009] In addition to the above-mentioned embodiments, the present invention can also have other embodiments. All technical solutions in the form of equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.

Abstract

The invention relates to an insulated operating rod, and is particularly applicable to temporary wiring for test and maintenance to a high-altitude device and operated on the ground. At present, high-altitude test wiring for the maintenance and the test to a power transmission device is relatively difficult, and certain unsafe factors affect the device and operators. The multi-angle operating rod provided by the invention is composed of a wiring clamp, a specific push-pull rod and a fixed bracket; the wiring clamp consists of an upper clamp jaw and a lower clamp jaw, and the lower clamp jaw moves along pulleys; a steel wire rope connecting an upper pulley and a lower pulley is controlled by a specific push-pull mechanism operated by lifting a long rod; the specific push-pull mechanism is provided with a locking mechanism capable of ensuring a clamping force of the clamp jaw; a mounting hole located between the upper clamp jaw and the lower clamp jaw is long and sloping, and enables the clamp jaws to be tightly clamped and generate transverse friction movement at the same time, thereby overcoming an oxidation film at a wiring position. The invention enables the conventional high-altitude working to be completed on the ground, fundamentally avoids danger caused by climbing, and greatly improves working conditions for the field operators.

Description

technical field [0001] The invention relates to an insulating operating rod, which is especially suitable for temporary wiring when the ground faces high-altitude equipment for testing or maintenance. Background technique [0002] At present, it is difficult to conduct high-altitude test wiring for substation equipment maintenance and testing. For the wiring points that cannot be directly touched, operators need to climb up the equipment or use tower cranes and high-altitude buckets for wiring. Some equipment tower cranes and high-altitude buckets The jib truck cannot reach it, and climbing equipment is not allowed. It is difficult and inefficient to use the ladder to move. The labor intensity of the test operators is high, the working hours are prolonged, and there are certain unsafe factors for equipment and personnel. Thereby, people are eager to have a kind of operating stick that can overcome above-mentioned defective to come out. Contents of the invention [0003] T...
