Abstract

The utility model discloses a bolt dismounting auxiliary tool, which comprises a screw head fixing plate, a strong magnet, a fixing frame, a spring hinge and an L-shaped clamping jaw; the fixing frame is sleeved on the outer side of the strong magnet; the fixing frame is fixed on the bottom surface of the screw head fixing plate; an L-shaped clamping jaw is fixed on each of two sides of the screw head fixing plate through a spring hinge; the screw head fixing plate is provided with a cross-shaped screw head positioning groove which is arranged along the diagonal line of the screw head fixing plate. The size of the screw head positioning groove is matched with that of a fixing bolt on the wiring board, after the screw head of the fixing bolt is inserted into the screw head positioning groove, the screw head of the fixing bolt is limited in freedom degree by the positioning groove when the nut is rotated, the situation that the fixing bolt and the nut rotate simultaneously cannot occur, and the working efficiency is improved; and elasticity through the spring hinge makes two L shape jack catchs the wiring board tightly, prevents to drop, avoids fixing bolt to drop, and alone can carry out fixing bolt's on the wiring board dismouting, improves the efficiency of construction.

Description

Bolt dismouting appurtenance
The technical field is as follows:
the utility model relates to a power supply maintenance appurtenance field, concretely relates to bolt dismouting appurtenance.
Background art:
in recent years, with the development of economy, regional power grids are also changed greatly, the number of substations governed by each power supply bureau increases year by year, hundreds of new primary equipment is added, and the maintenance workload is huge.
The fixing bolt on the primary equipment wiring board of the old transformer substation governed by the power supply bureau is easy to generate corrosion phenomenon due to long-term exposure in the open air environment, and must be processed and replaced in time. The existing dismounting and mounting method is mainly carried out by using an open end wrench, a box end wrench, a monkey wrench and an electric ratchet wrench, but in the tools, a maintainer needs to use another wrench to clamp the other end of the fixed bolt so as to prevent the fixed bolt and the nut from rotating simultaneously; when the fixing bolt is dismounted, the fixing bolt is often rusted, jammed and difficult to dismount, and when the situation occurs, force is applied by both hands of a maintainer to meet the force required by loosening the fixing bolt, so that the spanner for preventing the nut from rotating along with the fixing bolt cannot be avoided, only hands of the maintainer can be increased to work, and the efficiency is extremely low; because primary equipment is generally on the framework apart from ground 1.5 meters and more than 1.5 meters, the maintainer moves inconveniently, easily takes place danger, and after unscrewing the nut, if the spanner is not fixed with the spiral shell head, fixing bolt falls to ground, causes the unnecessary injury, and the maintainer must in time regain the screw still, has increased high altitude construction intensity of labour, influences the maintenance progress, has increased the time that has a power failure, influences work efficiency.
The utility model has the following contents:
the utility model aims to provide a bolt dismounting auxiliary tool which is convenient to use and improves the efficiency,
the utility model discloses by following technical scheme implement:
an auxiliary tool for disassembling and assembling a bolt comprises a screw head fixing plate, a strong magnet, a fixing frame, a spring hinge and an L-shaped clamping jaw;
the fixing frame is sleeved on the outer side of the strong magnet; the fixing frame is fixed on the bottom surface of the screw head fixing plate; the two sides of the screw head fixing plate are both fixed with the L-shaped clamping jaw through the spring hinge; the cross-shaped screw head positioning groove is formed in the screw head fixing plate and is arranged along the diagonal line of the screw head fixing plate.
Preferably, the strong magnet and the fixing frame are in interference fit.
Preferably, the screw head fixing plate and the fixing frame are fixed through a connecting bolt.
The utility model has the advantages that: the size of the screw head positioning groove is matched with the size of the screw head of the fixing bolt on the wiring board, after the screw head of the fixing bolt is inserted into the screw head positioning groove, the degree of freedom is limited by the screw head positioning groove of the fixing bolt when the nut is rotated, the situation that the fixing bolt and the nut rotate simultaneously is avoided, and the working efficiency is improved; and elasticity through the spring hinge makes two L shape jack catchs the wiring board tightly, prevents to drop, avoids fixing bolt to drop, and alone can carry out fixing bolt's on the wiring board dismouting, improves the efficiency of construction.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a top view of the screw head fixing plate of the present invention;
FIG. 3 is a top view of the strong magnet and the fixing frame of the present invention;
fig. 4 is a schematic view of the present invention in use.
In the figure: the device comprises a screw head fixing plate 1, a strong magnet 2, a fixing frame 3, a spring hinge 4, an L-shaped clamping jaw 5, a screw head positioning groove 6, a connecting bolt 7, a wiring board 8 and a fixing bolt 9.
The specific implementation mode is as follows:
as shown in fig. 1 to 4, an auxiliary tool for disassembling and assembling a bolt comprises a screw head fixing plate 1, a strong magnet 2, a fixing frame 3, a spring hinge 4 and an L-shaped jaw 5;
the fixing frame 3 is sleeved on the outer side of the strong magnet 2; the fixing frame 3 is fixed on the bottom surface of the screw head fixing plate 1; an L-shaped clamping jaw 5 is fixed on each of two sides of the screw head fixing plate 1 through a spring hinge 4; a cross-shaped screw head positioning groove 6 is formed in the screw head fixing plate 1, and the screw head positioning groove 6 is arranged along the diagonal line of the screw head fixing plate 1;
the screw head positioning groove 6 is a through groove;
when the device is used, one surface of the utility model for fixing the strong magnet 2 faces downwards, the top surface of the screw head fixing plate 1 is attached to the ground of the wiring board 8, the screw head of the fixing bolt 9 is inserted into the screw head positioning groove 6, the L-shaped clamping jaws 5 are adjusted, the L-shaped clamping jaws 5 are hung on the wiring board 8 positioned above, and the two L-shaped clamping jaws 5 tightly hold the wiring board 8 through the elasticity of the spring hinge 4 to prevent falling off; after the nut on the fixing bolt 9 is screwed off, the fixing bolt 9 is attracted by strong magnetism, and the falling is avoided;
in order to prolong the service life of the screw head fixing plate 1, the screw head fixing plate 1 can be made of stainless steel, and the fixing frame 3 is used for fixing the strong magnet;
the size of the screw head positioning groove 6 is matched with the screw head size of the fixing bolt 9 on the wiring board 8, after the screw head of the fixing bolt 9 is inserted into the screw head positioning groove 6, when the nut is rotated, the screw head of the fixing bolt 9 is positioned in the groove to limit the degree of freedom, the situation that the fixing bolt 9 and the nut rotate simultaneously can be avoided, and the work efficiency is improved.
Fixed frame 3 is made for the nylon board, and strong magnet 2 is interference fit with fixed frame 3, and the card that strong magnet 2 is firm avoids droing in fixed frame 3.
The screw head fixing plate 1 and the fixing frame 3 are fixed through the connecting bolt 7, and are convenient to detach and replace.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
