Description
Technical field
The utility model relates to a kind of crane bar, belongs to power engineering field.
Background technology
In 10kV distribution line and tranformer protection, use a large amount of fuse switches; in real work; in the time pulling open crane and have a power failure work; crane bar very easy to use; but while recovering power transmission after transformer service restoration power transmission or the insurance of replacing cartridge fuse; use crane bar that protective tube is hung in crane, often can not once-through operation success.Especially on shaft tower, use crane bar by protective tube when hanging in crane, particularly limit phase, because personnel on bar move inconvenience, cartridge fuse can not be mutually vertical with crane bar, causes crane bar head and protective tube to have certain angle, and protective tube does not have fixing point, be difficult to once hang up, and cartridge fuse very easily comes off, equipment causes damage, jeopardizes operator safety on pedestrian and bar.Because crane position is generally higher, staff just can operate after working head need to being aimed at, in use, due to operational environment difference, and operated by different staff, the crane of high position is difficult for observed, and is not easy to find whether epidermis has damage, can cause potential safety hazard.In addition, existing crane bar also has and much has electroscope function, but its complex structure, and cost is high, is inconvenient to use.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of simple and reasonable, handled easily, is convenient to observe, and cost is low, and can strengthen fail safe, is convenient to the crane bar of safeguarding.
Crane bar described in the utility model, comprise top insulating bar and afterbody insulating bar, between top insulating bar and afterbody insulating bar, connecting rod is set, between connecting rod and top insulating bar, afterbody insulating bar, be all connected by connecting thread, insulating bar top, top arranges crane working head, and upper lateral is installed cross bar, the hinged magnifying glass bracket in cross bar both sides, magnifying glass is set on magnifying glass bracket, and afterbody insulating bar end arranges electroscope joint, on electroscope joint, electroscope is installed.
Top insulating bar can be connected by middle connecting rod with afterbody insulating bar, can be fastenedly connected by the screw of externally threaded double-screw bolt and internal thread successively, make the crane working head at top at the top of whole crane bar, electroscope is in the bottom of whole crane bar, need to operate fuse switch time, use the operation of crane working head, in the time of needs electrical verification, crane bar is put upside down end to end, carry out electrical verification with the electroscope of afterbody, easy to use, simple in structure, cost is low; The magnifying glass hinged with top insulating bar can be in the time that crane working head operates, magnifying glass is overturn, make magnifying glass be positioned at crane working head outside, be convenient to the situation of crane bar working head and fuse switch to amplify, convenient observation, and accurately operation, increase work efficiency, and whether observable crane is excellent before operation, improves the fail safe of operation, be convenient to timely replacing, avoid unnecessary loss and dangerous generation.
Described crane working head comprises the support bar that is vertically arranged on insulating bar top, top, and support bar one side arranges the first working beam of level, and opposite side arranges L shaped the second working beam.In the time that fuse switch is pulled open, use the first working beam to penetrate cartridge fuse annulus and operate; In the time that fuse switch is closed, use L shaped the second working beam to be placed on annulus bottom, bar head and cartridge fuse are fixedly operated.
The beneficial effects of the utility model are:
Simple in structure, easy to use, the connecting rod of setting can be selected number according to the position of fuse switch, easy to operate; Crane bar is put upside down end to end, got final product work and the electrical verification work of complete operation fuse switch, easy to use; The magnifying glass arranging, the course of work that can amplify crane working head and fuse switch, is easy to observe and operation, can increase work efficiency and improve processing safety.
