Abstract
The utility model relates to an overhauling tool for a power transmission line, and in particular relates to a rope ladder pulley for overhauling the power transmission line. The pulley comprises two pulley wheels on a support and is characterized in that the support for mounting the two pulley wheels consists of a U-shaped support I and a U-shaped support II, the two supports are connected by a fixing plate, the inner side of the U-shaped support I is provided with two relatively distributed rectangular brake plates, a guide shaft and a lead screw are arranged between the two side plates of the U-shaped support I and are in parallel to shafts for fixing the pulley wheels, holes at the upper part of the two rectangular brake plates are matched with the guide shaft, thread holes of the two brake plates are matched with the lead screw, relative surfaces of the lower parts of the two brake plates are fixedly provided with brake sheets, a handle is arranged at one end of the lead screw, and the screwing direction of the lead screw is opposite to the screwing direction of a matching part of the two brake plates. Through the technical scheme of the utility model, based on the traditional pulley, a brake device is additionally provided so that the rope ladder pulley can be conveniently fixed at any position of the power transmission line to meet the overhauling requirements.
Description
Technical field
The utility model relates to power transmission lines overhauling instrument, particularly power transmission lines overhauling and uses the rope ladder coaster.
Background technology
When power transmission lines overhauling, when stockbridge damper positioning etc. is studied for a second time courses one has flunked, handled to the lead behind the crane short in the process, need to adopt the rope ladder coaster that rope ladder and maintainer are moved to the service work position from the suspension clamp of transmission line wire.Existing rope ladder coaster is made up of two rack-mount pulleys; During use two pulleys are placed on the transmission line, on the support under two pulleys, hang rope ladder, the mode that the maintainer overhauls on rope ladder; Because the effect of transmission line deadweight; The maintainer needs to move to lower from the eminence of transmission line, and when the rope ladder coaster drove in maintainer's moving process and overhauls, the rope ladder coaster often takes place can't be fixed and the phenomenon of positioning.Prevent that at present the mode that the positioning phenomenon takes place from mainly being that the maintainer adopts hand to brake, be very easy to crush maintainer's hand like this.How the rope ladder coaster is fixed on maintenance position and the speed that the control rope ladder moves on lead, becomes transmission line high-altitude maintenance process urgent problem.
Summary of the invention
The purpose of the utility model is to overcome the defective that prior art exists, and provides a kind of power transmission lines overhauling of the control of the fixing and translational speed of rope ladder in the maintenance process of high-altitude of can conveniently realizing to use the rope ladder coaster.
For realizing above-mentioned purpose; The technical scheme of the utility model is: a kind of power transmission lines overhauling is used the rope ladder coaster, comprises two rack-mount pulleys, and the support that it is characterized in that installing two pulleys is made up of " U " shape support I and " U " shape support II; Be connected through fixed head between the two stands; In " U " shape support I installed inside the two relative rectangle braking vanes that distribute are arranged, the axis of guide and the leading screw parallel with the axle of fixed block are installed between the biside plate of above-mentioned " U " shape support I, the hole and the axis of guide on two rectangle braking vane tops match; The screwed hole and the leading screw at two braking vanes middle part match; Be fixed with brake block on the opposite face of two braking vane bottoms, at an end of leading screw handle be installed, the match thread rotary orientation at place of above-mentioned leading screw and two braking vanes is opposite.
The technical scheme of the utility model is on the existing basis of power transmission lines overhauling with the rope ladder coaster, has increased brake gear, drives two braking vanes through leading screw and oppositely moves, thereby coaster is fixed on the transmission line.The utlity model has rational in infrastructurely, can conveniently power transmission lines overhauling be fixed on optional position on the transmission line with the rope ladder coaster, to satisfy the maintenance needs.

Accompanying drawing 1 is the structural representation front view of the utility model;
Accompanying drawing 2 is the right view of the utility model accompanying drawing 1;
Accompanying drawing 3 is the vertical view of the utility model accompanying drawing 1.
Embodiment
Like Fig. 1,2, shown in 3; The pulley II 1 of left end is through on axle II 3 rotatable being installed in " U " the shape support II 2; The pulley I 6 of right-hand member is through on axle I 7 rotatable being installed in " U " the shape support I 8, about two " U " shape support be connected through fixed head 4, from top to bottom order is equipped with the axis of guide parallel with the axle of fixed block 9 and leading screw 10 between the biside plate of " U " shape support I; Installed inside in " U " shape support I 8 has the two relative rectangle braking vanes 11 that distribute; The hole and the axis of guide on two rectangle braking vane tops match, and the screwed hole and the leading screw at two braking vanes middle part match, and are fixed with brake block 15 on the opposite face of two braking vane bottoms; Left end at leading screw is equipped with handle 14, leading screw and two braking vanes match the place thread rotary orientation opposite.Through dismountable steady pin 12 rope ladder 13 is installed in two " U " shape support lower end.During the maintenance transmission line, pull down steady pin 12, power transmission lines overhauling is placed on the transmission line 5 with the rope ladder coaster, then rope ladder is suspended on the steady pin, and transmission line is between the brake block 15 on the two rectangle braking vanes.Need to overhaul when being fixed on a certain position on the transmission line with rope ladder; Through the handle rotating threaded shaft; Because the rotation direction of the screw thread that matches with two rectangle braking vanes on the leading screw is opposite; Such two rectangle braking vanes will move to the transmission line direction simultaneously, through brake block 15 transmission line are clamped, and power transmission lines overhauling is fixed on the transmission line with the rope ladder coaster.Clamping force through rotary handle adjustment brake block and transmission line just can realize that power transmission lines overhauling is with the travel speed of rope ladder coaster on transmission line.
