Abstract
The utility model relates to an electric power circuit maintaining tool, in particular to a pulley device for electric power circuit maintenance. The device comprises a pulley capable of being fixed between two fixing plates through a pin shaft in rotating mode and is characterized in that a hoisting shaft is arranged at upper ends of the two fixing plates and parallel to the pin shaft for fixing the pulley, a connecting shaft is arranged on the hoisting shaft in rotatable mode, an upper end of the connecting shaft is fixedly connected with the fixing plates of the pulley, and a long groove used for being matched with a cross arm on a pole is arranged on the fixing plates of the pulley. The electric power circuit maintaining tool has the advantages of being simple in structure and convenient to install and locate and the like. During use, the pulley can be fixed on the cross arm conveniently only by placing the long groove on the fixing plates of the pulley on the cross arm on the pole. Simultaneously, due to the fact that rotatable connection is adopted between the fixing plates and the pulley, angles between the pulley and the cross arm and dragging ropes of ground staff can be automatically adjusted, and the dragging ropes can be prevented from being twined with each other.
Description
Affiliated technical field
The utility model relates to a kind of power circuit maintenance tool, and particularly pulley gear is used in the power circuit maintenance.
Background technology
In the power circuit maintenance process, need the parts on ground be transported on the tower bar, the parts after maybe will changing are transported to ground from the tower bar.Present above-mentioned conveying all adopts pulley to be operated by the ground staff; But must take tower bar on fixing by the maintenance personal pulley; And the fixed form of existing pulley is to adopt iron wire that pulley is fixed on the cross-arm on the tower bar; On the one hand fixing fail safe can not guarantee, and is comparatively inconvenient fixedly the time in the high-altitude on the other hand.
Summary of the invention
The purpose of the utility model is the defective that overcomes prior art, provides lead fixed convenient, fixed pin type porcelain vase.
For realizing above-mentioned purpose; The technical scheme of the utility model is: pulley gear is used in a kind of power circuit maintenance; Comprise through the rotatable pulley that is fixed between two fixed heads of bearing pin, it is characterized in that the parallel hoisting axis that is equipped with the bearing pin of fixed block, the rotatable connecting axle that is equipped with on hoisting axis in the upper end of two fixed heads; Connecting axle upper end is fixedly linked with the pulley fixed head, have on the pulley fixed head be used for the tower bar on the elongated slot that matches of cross-arm.
Above-mentioned pulley and fixed head all adopt insulating material to process.
Rotatable connection the between above-mentioned hoisting axis and the connecting axle is that connecting bushing is contained in the hole of vertical lifting axis on the hoisting axis.
The utlity model has characteristics such as simple in structure, that installing and locating is convenient.Only need during use the elongated slot on the pulley fixed head is put on the cross-arm on the tower bar; Just can conveniently pulley be fixed on the cross-arm; Simultaneously owing to adopt rotatable the connection between fixed head and the pulley; So just can regulate the angle between pulley and cross-arm and the ground staff's pull rope automatically, prevent that pull rope from twining each other.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is the left view of the utility model accompanying drawing 1.
Embodiment
Like Fig. 1, shown in 2; Pulley 4 is through bearing pin 5 rotatable being fixed between two fixed heads 6; The parallel hoisting axis 3 that is equipped with in the upper end of two fixed heads with the bearing pin of fixed block; The rotatable connecting axle 2 that is equipped with on hoisting axis, connecting axle upper end is fixedly linked with pulley fixed head 1, have on the pulley fixed head be used for the tower bar on the elongated slot 8 that matches of cross-arm 7.For guaranteeing its insulation property, pulley and fixed head all adopt insulating material to process.Rotatable connection the between above-mentioned hoisting axis and the connecting axle is that connecting bushing is contained in the hole of vertical lifting axis on the hoisting axis, also can adopt existing other modes, its objective is to make rotatable connection the between fixed head and the pulley.
When the maintenance transmission line, the maintainer is carried to this device on the tower bar, the elongated slot on the pulley fixed head 18 is inserted on the cross-arm 7 just can accomplish this Unit Installation, use.
