Quick push-pull rotary spacing rod spanner

Technical Field

The utility model relates to the field of electric tools, in particular to a spanner for disassembling and assembling a spacer.

Background

The spacer is arranged on the split conductor, can keep a certain space distance between the sub-conductors, and is used for inhibiting the mutual winding, whipping and friction of the sub-conductors caused by the vibration of the conductors and breeze vibration. The damaged spacer which bears the electromechanical load for a long time is usually replaced when the routine technical improvement is overhauled and overhauled in an electrified way, and the spacer wrench is a special tool for installing and removing various types of spacers and plays an important role in overhauling the power transmission line.

The old-fashioned spacer spanner adopts a ratchet and pawl mechanism (a unidirectional intermittent motion mechanism consisting of a ratchet and a pawl), wherein the ratchet is a freely rotating gear, the pawl is a small lever capable of preventing the gear from rotating, a spring is often used for ensuring that the ratchet and the pawl keep in contact, and the back and forth switching is realized by adjusting a handle connected with a driven part, so that the mechanism has the defects of noise, incapability of overhigh working efficiency, high labor consumption, unstable performance, easy damage of the spring and the like.

Further, the outer end of the travel rod is in threaded connection with the rotary travel rod.

Further, the cross section of the inner end of the travel bar is square, and the cross section of the inner cavity of the guide sleeve is square.

Further, an anti-skid sleeve is arranged on the long arm of the pulling handle.

During operation, the movable baffle plate is rotated, so that the movable baffle plate and the rotary travel rod are on the same straight line, after the movable baffle plate passes through the tool operation holes of the support arm of the spacing rod and the clamping head, the movable baffle plate is opened, the support arm and the clamping head are positioned between the movable baffle plate and the clamping movable bearing, the rotary spanner handle is rotated, the total length of the rotary travel rod and the travel rod is adjusted, namely, the distance between the movable baffle plate and the clamping movable bearing is adjusted, and then the spanner handle is pushed and pulled to lock. The beneficial effects of the utility model are as follows:

1. compared with the existing spacer spanner, the push-pull structure has the advantages that the main locking stroke of the spacer is finished by pushing and pulling the handle, the rotation is used as auxiliary locking, the rotation distance is very short, the working time and the manpower are greatly saved, the working efficiency can be improved, and the safety is further improved;

2. compared with the old type spacing rod wrench, the spacing rod wrench is simple and light in weight, convenient to lift in the use process, and capable of greatly saving the physical strength of workers;

3. the utility model does not need a spring structure, greatly reduces the cost of frequent replacement of old people, and has a service life far longer than that of the old people;

4. the push-pull structure has low noise.
