Abstract
The utility model relates to a power equipment and specifically relates to a wire tensioning pulley. The wire tensioning pulley includes a support, a pulley and a pulley pin. The pulley is supported in the support through the pulley pin. The wire tensioning pulley is characterized in that the support is U-shaped; the upper end of the support is open while the lower end of the support is connected with a pulley base; one end of an arc-shaped pulley cover is connected with one side of the support through a pin roll while the other end of the pulley cover is connected with the other side of the support through a drag-hook-type bolt; the pulley cover and the pulley constitute an oval wire threading cylinder hole; the pulley base is provided with a lug provided with a connection hole; the pulley base is fixed with a U-shaped or an L-shaped bolt for use. The pulley base is fixed with the U-shaped or the L-shaped bolt. Then a to-be-tensioned wire is disposed on the pulley and the pulley cover is locked up tightly. The wire can be adjusted and fixed through a pull force digital display in a tensioning process. The wire tensioning pulley provided by the utility model has advantages of being convenient in operation, safe in use, high in working efficiency and the like.
Description
Technical field
The utility model relates to electric power facility, specifically a kind of easy to operate, use safety, snatch block that operating efficiency is high.
Background technology
At present, making somebody a mere figurehead of electric power system mesohigh line, burying underground of electric pole all needs with wanting snatch block, existing snatch block is made up of support, pulley and pulley pin, pulley is supported in support through pulley pin, and existing pulley, in Construction of Tension Stringing process, has the following disadvantages: the one, need to find hitch point, pulley easily comes off from bar, has increased staff's danger; The 2nd, pulley bore is too little, can not be directly by the tie point of wire and rope, and need operating personnel on bar to open pulley pin, shouldered with shoulder simultaneously, waste time and energy; The 3rd, electric wire is easily stuck between pulley and support and causes card line phenomenon, easily causes electric wire surface mechanical damage, and in the time running into terminal, electric wire blocks and can not pass through smoothly pulley, easily causes down bar when serious; The 4th, reserved needs of wire lengthens, and causes waste, and the 5th, conductor tension is unbalanced, and what cause the accident takes place frequently.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of easy to operate, use safety, snatch block that operating efficiency is high.
The utility model solves the technical scheme that its technical problem adopts.
A kind of snatch block, comprise support, pulley and pulley pin, pulley is supported in support through pulley pin, it is characterized in that support is the open U font in upper end, the lower end of support is connected with pulley base, and pulley lid one end of arc is connected with support one side through bearing pin, the other end of pulley lid is connected with the opposite side of support through drag hook type bolt, pulley lid and pulley form the oval line cylinder hole of crossing, and pulley base is provided with the lug with connecting hole, and pulley base is fixed through U-shaped or L shaped bolt.
The utility model can be provided with the supervisory circuit for detection of conductor tension information, described supervisory circuit comprises the pressure sensor that microcontroller chip, control signal input be connected with microcontroller chip, the pulling force indicating module that input is connected with microcontroller chip, indicating module can adopt pulling force nixie display, at least inlays two pressure sensors in the cambered surface of pulley.
The utility model can be connected with pulley pin through deep groove ball bearing respectively at pulley two ends, and pulley and support gap are reduced, and prevents card line phenomenon.
When the utility model uses, first through U-shaped or L shaped bolt fixed block seat, again electric wire to be strained be placed on pulley and lock pulley lid, in stringing process, can regulate and securing electric lines by pulling force nixie display, have easy to operate, use safety, operating efficiency advantages of higher.
