Description

Rotatable voltage transformer lifting appliance

Technical field

The utility model relates to a kind of lifting appliance that voltage transformer is installed.

Background technology

Distribution transformer, the low-tension distribution box of China's rural power grids more than 95% all is installed on the stand of electric pole, and the stand area is little, highly is about 2.5m, distribution transforming and switch box in addition, and volume and weight is big.When vast rural area and samll cities and towns installed under not having the situation of Special Hoisting Equipment, difficulty was very big, and dangerous.Be that pulley is hung on the electric pole fuse support in the past, again rope is enclosed within on the pulley and up draws, when moving to, the voltage transformer level is pulled away from stand near the voltage transformer stand with manpower, hang mutually with voltage transformer to prevent stand, continue again then up that the people draws, pickaback, the thick stick top, overexert sometimes or voltage transformer heavier, the fuse support will be out of shape, glide, the staff squeezes wound, the accident of weighing wounded happens occasionally, not only labour intensity is big, effort, time-consuming, and can't guarantee the safety of the person, equipment.

Summary of the invention

The purpose of this utility model is the problem that exists at above-mentioned prior art, a kind of rotatable voltage transformer lifting appliance is provided, this device has in light weight, volume is little, is easy to carry advantages such as simple installation, the operation save time, laborsaving, alleviated working strength of workers greatly, got rid of safety hazard, be a kind of safe, reliably load and unload the constructing device of voltage transformer.

The technical solution of the utility model is such: a kind of rotatable voltage transformer lifting appliance, form by rotatable A-frame and bottle gouard moved by hands, the concrete structure of its A-frame is: the middle part of electric pole be positioned at the voltage transformer stand above, fix down two fill the span of a man's arms hoops and be connected with horizontal pivoted arm, top at electric pole equals the position of horizontal pivoted arm length with descending two distances of filling the span of a man's arms hoop, fix one last two hoop and be connected of filling the span of a man's arms with steel rope, the other end of steel rope is connected the outer end of horizontal pivoted arm, the outer end of horizontal pivoted arm connects bottle gouard moved by hands, like this, just constituted the hoisting bracket of an equilateral right-angled triangle.

Described last two fill the span of a man's arms hoop and being connected of steel rope, and are a kind of right angle link plate to be hinged on connect two and fill the span of a man's arms on the bolt that binds round, and steel wire loop is contained on the bearing pin of right angle link plate.

Described steel rope is connected with horizontal pivoted arm, is steel rope is hung on the bail on the horizontal pivoted arm termination.A kind of clevis eye can also be sleeved on the horizontal pivoted arm and encircle, steel rope is sleeved on again on the bearing pin of clevis eye.

Described horizontal pivoted arm and following two is filled the span of a man's arms being connected of hoop, be to weld a kind of connecting panel of along continuous straight runs opening in the vertical two semi-ring hoop positions of filling the span of a man's arms hoop down, and it is hinged with horizontal pivoted arm to pass through little axle.

The utility model compared with prior art owing to adopted a kind of triangular supports structure that is made of electric pole, steel rope, horizontal pivoted arm, makes device reliable and stable, and is stressed reasonable.Because at following two connecting panels of filling the span of a man's arms a kind of along continuous straight runs opening of welding on the semi-ring hoop of hoop, and hinged with horizontal pivoted arm by little axle, therefore, can the horizontal pivoted arm of realization do the rotation of horizontal direction around electric pole together with A-frame integral body, corner can reach 180 degree.Because A-frame has utilized electric pole to make a square edge, hypotenuse is selected gentle good, the lightweight steel rope of shape for use, therefore, unitary construction is light and handy, in addition, attaching parts has utilized electric armour clamp dexterously: two gauge members such as hoop, right angle link plate, clevis eye of filling the span of a man's arms make that it is simple in structure, rotate flexibly, the folding dress is convenient.The utility model has solved and has lifted the difficulty of voltage transformer and the dangerous problem of existence in the past, has substituted thoroughly in the past that the people draws, pickaback, and the stupid way on thick stick top has alleviated labour intensity, has improved work efficiency, has improved safe reliability, has improved execution conditions.The most suitable place, the cities and towns at county level of traffic difficulties and the vast rural area that does not have crane and crane to arrive of this device, lifting voltage transformer and comprehensive distribution box use.

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
