Description

A steel pipe tower cross arm portable hand pull rod

technical field

The utility model belongs to the technical field of safety operation and maintenance, and in particular relates to a portable hand-supporting rod with a steel pipe tower cross arm.

Background technique

In recent years, due to the rapid development of urban construction and the rapid increase of electricity load, the original power supply network can no longer meet the needs of the development of electricity load. ; The traditional iron tower occupies a large area, and its shape is not in harmony with the modern urban environment; the use of high-voltage cables is expensive, and the use of reinforced concrete poles has not been able to solve the problems of longitudinal and circumferential cracks; The tip-shaped steel pipe pole with circular or polygonal cross-section has simple structure, clear force, easy processing and manufacturing, convenient construction, safe and reliable operation, and less maintenance workload; but the existing steel pipe tower is very empty between the tower pole and the cross arm , there is no device that can be held by hand, making it very dangerous for maintenance personnel to work on it, so a hand-held pull rod device that can be temporarily supported is needed to protect maintenance personnel.

Utility model content

The technical problem to be solved by the utility model is to provide a steel pipe tower with simple structure and easy operation in view of the fact that there is no hand-holding device on the cross arm of the steel pipe tower rod in the prior art, which makes it difficult for maintenance personnel to work on the cross arm. Cross arm portable hand pull rod.

The technical solution adopted in order to achieve the above purpose is: a steel pipe tower cross-arm portable hand pull rod, including a pull rod body with a clamp at the front and a locking mechanism at the rear, a drawstring at the rear of the clamp, and A spring is arranged at the rear of the clip, and the locking mechanism includes a support rod and a locking module, and the support rod is connected to the pull rod body through a butterfly bolt.

The locking module includes a card seat and a ratchet arm, one end of the ratchet arm is movably connected with the card seat, and a ratchet is provided on the outside of the other end of the ratchet arm, and the ratchet is passed through an elastic clip arranged on the card seat. Connect with the deck.

A pull ring is arranged at the end of the pull rope, and two winding posts are arranged at the pull ring on the outer wall of the pull rod body.

The spring is a compression spring.

The holding clip is a scissors-shaped holding clip, and the front part of the holding clip is U-shaped.

The holding clip is movably connected with the pull rod body through the central rotating shaft.

A switch column is arranged on the upper part of the elastic card.

The utility model uses a locking module to lock the device on the steel pipe tower, and then clamps the clamp on the insulator string set at the front end of the upper cross arm through the pull rod body, and pulls the rear part of the scissors-shaped clamp through the pull rope to make the rear The distance between the two arms is reduced, and then the insulator strings are clamped at the front, and then the support rod and the tie rod body are locked by butterfly bolts, and a certain angle is formed between the lower cross arm, so that the maintenance personnel can work on the cross arm Keep upright when going up and moving, and the center of gravity will not be unstable due to the center shift caused by this device; the holding clip is designed using the structural principle of scissors, and a compression spring is set between the tails of the two holding arms at the rear, which can play the role of the spring Make the holding clip at the maximum angle state, and set a pull wire between the two holding arms at the rear, and set a pull rope on the pull wire, so that when the pull rope is pulled, the pull wire can be tightened and compressed to compress the two holding clip arms The distance between them, so as to realize the tightening of the front part of the clip and ensure the support effect of the front end.

Two winding columns are set at the exit of the pull rope of the pull rod body, so that the pull rope can be wound and locked on it after being tightened, which not only simplifies the structure but also has a good locking effect. The flexible connection of the rod can not only realize the function of fast locking, but also realize the function of the telescopic rod. The locking module adopted is similar to the principle of handcuffs. The elastic card set on the deck can be quickly locked by the ratchet and the elastic card. It is tight, and the switch column is set on the upper part, which can be quickly removed after use, not only realizing the locking function but also realizing the function of quick removal, and the structure of this device is simple, easy to operate, and it is the largest under the same resource conditions. It has exerted its practical value to the maximum extent and is worthy of application and promotion.
