Abstract
A wrench for live working in high-voltage electrical apparatus mainly comprises a ratchet pawl component and a ratchet wheel; the ratchet pawl component is formed by a ratchet pawl round plate, an upper clamp plate and a lower clamp plate; an upper plate and a lower cover plate are respectively sleeved on the shoulders of the upper and low clamp plates in a rotating manner; one of the two extending ends of the upper cover plate is connected one of the two extending ends of the lower cover plate through a pin shaft, and the other ends thereof are fixed through a screw stud, and the other extending end of the lower cover plate is provided with a gripping head; a stay cord is tied in a hole of a pull rod fixedly connected to the ratchet wheel; a rubber band or a return spring is arranged between the hole of the pull rod and the pin shaft; and an insulating sleeve sleeved on a square shaft and a nut is further arranged. The wrench has the characteristics of simple structure, convenient use, and high safety, and serves as a special tool for charged maintenance of electric equipment.
Description
Technical field
The utility model relates to the spanner that bolt spins or dismantles, especially for the spanner technical field of High-Voltage Electrical Appliances livewire work.
Background technology
High-voltage electrical equipment is in service, often has to carry out the needs that livewire work is safeguarded.For example, if the bolt looseness on the electric equipment untimely fastening, can cause equipment security of operation accident.Carrying out fasteningly after the power failure again, is again that to produce institute unallowed, therefore, must carry out charged bolted operation in real time.The operator adopts some provisional ways to be handled, as, insulating cylinder of adjunction on solid wrench screws loosening bolt, for the solution of this type of problem, and the still not convenient so far specific purpose tool that uses.
The utility model content
The purpose of this utility model provides a kind of simple in structure, easy to use, safe, live working wrench of high-voltage electrical equipment that operating efficiency is high.
This novel purpose is achieved in that a kind of live working wrench of high-voltage electrical equipment, mainly is made up of pawl component and ratchet; Pawl component consists of: its disk that is provided with ratchet is sleeved on the square shaft, and train wheel bridge and lower plate are set in the place, upper and lower position of disk on the square shaft, and the external diameter of upper and lower clamping plate equates with the external diameter of this disk; Ratchet sleeve is contained on the ratchet disk, and is fixedly connected with pull bar on the ratchet, and place, pull bar outer end has the hole, and stay cord is bound on the hole; Upper cover plate and lower cover are sleeved on the shoulder of train wheel bridge and lower plate respectively rotationally, one overhanging end of upper and lower cover plate connects through bearing pin, another overhanging end of upper and lower cover plate is connected and fixed through bolt, and the other end overhanging end of lower cover is provided with as chuck fixing on high-voltage electrical equipment; The external diameter of upper and lower cover plate equates with the external diameter of ratchet; Be provided with rubber band or back-moving spring between the hole of pull bar and the bearing pin; Also have insulating sleeve: the internal orifice of its top section is shaped as the square adaptive with the square shaft shape, and the internal orifice of its underpart section is shaped as the regular hexagon adaptive with nut shape.
During use, the upper cover plate chuck is fixed on (latch on the chuck is stuck on the draw-in groove of support on the support of electrical equipment, bayonet socket on the chuck is stuck on the screw rod of support or the post or through being bolted on the support), again the insulating sleeve upper end is socketed on the square shaft lower end, the sleeve lower end is socketed on the nut, can carry out the bolted operation: the pulling stay cord, the ratchet on the pull bar clockwise rotates (overlooking), at this moment ratchet card post ratchet, square shaft rotates synchronously with ratchet, clockwise rotate thereby drive insulating sleeve, nut is clockwise rotated on screw rod, play the effect that screws nut, stay cord of every pulling, nut screws once, whenever loosens stay cord one time, under rubber band or action of reset spring, ratchet (overlooking) counterclockwise resets rotation once, at this moment, ratchet does not play braking action, and it is motionless that square shaft keeps.Therefore, by intermittently spurring stay cord, Song Dong nut is fastening the most at last.When bolt unscrewed operation, spanner turned over turnback, and the insulating sleeve upper end is socketed in the square shaft upper end and upward gets final product, and when just intermittently spurring stay cord, the ratchet inhour is rotated once, and square shaft drive insulating sleeve inhour synchronously rotates once.And when loosening stay cord, the clockwise return of ratchet, at this moment, it is motionless that square shaft keeps.
This novel beneficial effect is:
1, parts are few, simple in structure
Upper and lower clamping plate, ratchet (containing disk) but with square shaft also integrated setting, whole device only is made up of 7-8 part.There is not specific (special) requirements on the part processing.
2, reasonable in design, easy to use, fastening bolt efficient height is the desirable specific purpose tool of power equipment power-on serving.
3, safe
On the one hand, contact with equipment by insulating sleeve; On the other hand, operating personnel contact with pull bar by stay cord (insulating materials making).Thereby, being provided with the double hyer insulation protection between operating personnel and the charging equipment, safety in utilization is ensured conscientiously.
