Description
Technical Field
The utility model relates to a transformer bushing assembly and disassembly tools belongs to transformer repair tools technical field.
Background
In the electric power safety production, the maintenance of generating heat to transformer bushing joint is very important, and during the maintenance, we need to pull down the sleeve pipe and further investigate cause and fault point that cause generating heat. The common sleeve is directly fixed on the top of the sleeve by common screws, but the sleeve in the form is easy to damp and cause failure of the transformer, and the most widely applied at present is a COT type sleeve of Shanghai MWB company, and the sleeve is rotationally fixed on the top of the transformer by outer diameter threads.
The COT type sleeve of Shanghai MWB company is exactly like a general cap in shape, so the COT type sleeve is called a general cap, although the special characteristic of the mounting mode of the general cap is good in sealing performance, the general cap is very hard to dismount by bare hands, and the general wrench cannot directly loosen the general cap.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a transformer bushing assembly and disassembly tools, based on lever principle, can effectively solve the unable direct not hard up problem of shanghai MWB sleeve pipe general cap of ordinary spanner, solved the above-mentioned problem that exists in the background art effectively.
The technical scheme of the utility model is that: the utility model provides a transformer bushing assembly and disassembly tools, contains opening ring device, handle, screw rod and nut, opening ring device is for being equipped with open-ended annular structure, all is equipped with the rectangle tightening piece of outwards bending on the both ends lateral wall of opening part, and two rectangles tighten up the mutual parallel arrangement of piece, and two rectangles tighten up the piece and all are equipped with the through-hole, screw rod and handle fixed connection, screw rod pass the rectangle tighten up the through-hole on the piece and with nut screw-thread fit. The caliber of the opening ring device can be adjusted through the nut at the top end of the screw rod, so that loosening and force application are prevented.
The split ring is made of steel sheet. Because the steel sheet has the characteristics of strong tensile force, high toughness, difficult breaking and the like, when the military cap is disassembled and assembled, the opening annular device can be effectively prevented from deforming without exerting force.
The handle is made of rubber.
The handle is cylindrical, and the diameter of the handle is larger than that of the through hole in the rectangular tightening piece.
The utility model has the advantages that: the problem that the ordinary wrench can not directly loosen the Shanghai MWB casing pipe and the military cap can be effectively solved. The tool is simple in structure, convenient to carry, time-saving and labor-saving in operation, greatly reduces the working strength of maintainers, greatly improves the working efficiency of maintenance work, and can effectively guarantee the integrity and the maintenance quality of the sleeve during the maintenance of the sleeve.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the usage state of the present invention.
In the figure: the opening ring device 1, the handle 2, the screw rod 3, the nut 4, the rectangular tightening sheet 11 and the military cap 5.
Detailed Description
The invention will be further explained by way of example with reference to the accompanying drawings.
The technical scheme of the utility model is that: the utility model provides a transformer bushing assembly and disassembly tools, contains opening ring device 1, handle 2, screw rod 3 and nut 4, opening ring device 1 is for being equipped with open-ended annular structure, all is equipped with the rectangle tightening piece 11 of outwards bending on the both ends lateral wall of opening part, and two rectangle tightening pieces 11 are parallel to each other, all are equipped with the through-hole on two rectangle tightening pieces 11, screw rod 3 and 2 fixed connection of handle, screw rod 3 pass the through-hole on the rectangle tightening piece 11 and with 4 screw-thread fit of nut. The caliber of the opening ring device can be adjusted through the nut at the top end of the screw rod, so that loosening and force application are prevented.
The split ring 1 is made of steel sheet. Because the steel sheet has the characteristics of strong tensile force, high toughness, difficult breaking and the like, when the military cap 5 is assembled and disassembled, the annular steel sheet can be effectively prevented from deforming without exerting force.
The handle 2 is made of rubber.
The handle is cylindrical, and the diameter of the handle is larger than that of the through hole in the rectangular tightening piece.
During actual field operation, firstly the nut 4 is loosened, the opening annular device 1 is clamped outside the military cap, then the nut 4 is rotated to adjust the caliber of the opening annular device to be matched with the outer diameter of the sleeve and be firm enough to prevent loosening and force application, and finally the handle 2 is rotated to drive the military cap to rotate, so that the military cap can be detached. Therefore, the clamping groove of the sleeve positioning pin can not be damaged, and time and labor are saved, and the device is simple and convenient.
At present, the special disassembling tool is widely applied to actual maintenance work, and the practicability and the efficiency of the special disassembling tool are well proved by field maintenance.
