Abstract
The utility model discloses a miniature stringing pulley which is applied in erection and construction of leads of a power transmission line. The miniature stringing pulley comprises a vehicle frame and a lead wheel; a hanging plate is arranged on the vehicle frame, hinged with an edge column at one side and plugged into another edge column through a main plug pin; the lower end of each of the edge columns is provided with a supporting seat; the supporting seat is a U-shaped snap-gauge, and fastening screwed holes are arranged in a layer of the snap-gauge of the U-shaped supporting seat for tight pressing and fixing. The structure of the stringing pulley provided by the utility model is utmostly simplified, connection manners of all the components are also utmostly simplified, so the miniature stringing pulley has a light weight, is convenient to carry and can be conveniently conveyed to an iron tower to begin to pull a guiding rope as fast as possible after line laying of a dynamic parachute. The supporting seats at the lower end of the edge columns are the U-shaped snap-gauges which can be in clamp connection with angle iron of the iron tower, then bolts are used for tight pressing and fixing, and finally, traction begins.
Description
Technical field
The utility model relates to the auxiliary implement that uses in a kind of wire erection work progress of transmission line, refers in particular to a kind of light-duty wires-erecting pulley that strop is passed through smoothly.
Background technology
In transmission line construction, Poling Construction is one of work progress of most critical, and spreading guiding rope is the main contents of this work progress.At present, spreading guiding rope at first is to adopt propeller-parachuting lightweight aircraft unwrapping wire, after taking preliminary leading rope on the transmission tower with the propeller-parachuting lightweight aircraft, again preliminary leading rope is put into the coaster that is suspended on steel tower top shelf line position, then with hauling machine traction guiding preliminary leading rope.The guiding preliminary leading rope is come the traction of secondary guide rope by also driving guiding in coaster, thereafter, successively steel wire rope, pull rope traction are put in place again, the connector of back, limp, traction steel rope of cable etc. also pass through coaster, pull rope is connected with limp, and the back of limp is cable wire or polytomic wire etc.Coaster need to be hung on each strain tower during construction.Present coaster mostly is used with large-tonnage hauling machine and tension pay-off machine, generally is applicable to use when the traction transmission pressure.But the guiding preliminary leading rope is the rope that a kind of high-intensity lightweight density is little, wire diameter is thin, and when the starting stage that installs electric wiring unfolded, its tractive effort and tension force were very little, and pulling force is very not large.If use bull block group unfolding preliminary leading rope to carry out leading five operations, it is supporting, and to walk board size very large, and preponderance causes that preliminary leading rope is born to be towed, and can aloft not move.And the transportation of large-scale coaster and installation all need the more time, if carry out towage after by the time bull block being installed, have obviously just prolonged the duration again.
The utility model content
The utility model technical issues that need to address provide a kind of light Miniature wires-erecting pulley that is adapted to set up the use of power transmission line initial stage.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Miniature wires-erecting pulley, comprise mainly by two edge columns, be positioned at the vehicle frame that the link plate with hanging hole on two edge column tops forms, be provided with a horizontal main shaft that is installed with guide roller between two edge columns, the edge column of link plate and a side is hinged by bearing pin, be provided with corresponding pin hole on another root edge column of the other end of link plate and vehicle frame and pass through main latch grafting, also be plugged with the anticreep latch on the lateral pin of main latch, edge column at corresponding pin hole is provided with the baffle plate that has certain interval with the edge column side, and the anticreep latch is inserted in this gap; Main shaft by the screw fastening on the main shaft both ends of the surface on the dual-side column; Between two edge columns below guide roller connecting bolt is set.
Further improvement of the utility model is: the lower end of described edge column respectively arranges a supporting seat, and this supporting seat is U-shaped clamp, arranges on one deck clamp of U-shaped supporting seat and holds out against the fixedly fastener hole of usefulness.
Owing to adopted technique scheme, the obtained technological progress of the utility model is:
The structure of wires-erecting pulley of the present utility model has reached to be simplified most, the connected mode of each parts also reaches to be simplified most, so it is lightweight, easy to carry, can transport on the steel tower easily, so that behind propeller-parachuting lightweight aircraft unwrapping wire, can begin as early as possible to draw preliminary leading rope.The supporting seat of edge column lower end is U-shaped clamp, can be connected on the angle steel of steel tower, then holds out against fixing can the beginning with bolt and draws.
