Abstract
The utility model discloses a special tool for disassembling the three-piece bolts of vehicle tires and comprises an arc-shaped plate; a plurality of hexagonal holes are alternately arranged on the arc-shaped plate; the size of the hexagonal hole is matched with the nut in the three-piece tire bolts; and the spacing locations of the hexagonal holes are matched with the spacing locations of the three-piece tire bolts. When the special tool is used to disassemble the three-piece tire bolts, two hexagonal holes of the arc-shaped plate are sleeved on two adjacent nuts of the three-piece tire bolts, so that the tire bolt disassembly machine can be fixed at the quadrangular location of a middle sleeve of the three-piece tire bolts, and the nuts and the middle sleeve of the three-piece tire bolts can be removed when the tire bolt disassembly machine starts up; therefore, the tool can easily and effectively remove rusted and seized three-piece tire bolts and improve the disassembly efficiency of the three-piece tire bolts so as to save maintenance costs and avoid potential safety problems.
Description
Technical field
The utility model relates to a kind of special tool of vehicle tyre three-piece Bolt dismantling.
Background technology
At present, the rear portion overside tire of most of large-scale self lighting type vehicle adopts the three-piece bolt, be illustrated in figure 1 as in the self lighting type vehicle rear portion, the overside tire is by the bolted scheme drawing of three-piece, so-called three-piece bolt comprises screw rod 31, middle cover 32 and nut 33, screw rod 31 passes the fixed orifice of home record tyre rim 7, middle cover 32 is provided with negative thread and outside thread, one end termination is a quadrangle 4, middle cover 32 is arranged in the fixed orifice of overside tyre rim 6, the negative thread of middle cover 32 is twisted on screw rod 31, nut 33 is twisted on the outside thread of middle cover 32, the advantage of this three-piece bolt is to fix single tyre rim, has guaranteed the tautness of tire bolt of rear end plate.When trailing wheel overside tire need be changed, the nut that use tire bolt removing machine puts in pulling down just can be changed the overside tire, has improved the efficient of changing of tire, so the three-piece bolt has obtained using widely.But when needing to change rear portion overside tire after vehicle uses, the outside thread corrosion of nut and middle cover, the situation of killing often occur, when turning nut, middle cover can screw out from screw rod, and this moment, the overside tyre rim was followed out together, had brought trouble to changing of tire.Because the tyre rim volume inside is narrow and small, can't carry out effectively fixingly by spanner to nut, promptly use spanner that nut fix, when overlapping in the tire bolt removing machine is dismantled, its moment is very big, and staff can't carry out effectively fixing to spanner at all; Therefore dismantle the middle cover and the nut of corrosion, adopt cutter centered cover and nut to cut off mostly, so need fire operation, and in the process of cutting off, occur now and then tyre rim is cut bad situation appearance, even centered cover and nut have carried out successfully cutting off, because the temperature of cutter flame is higher, can cause the material generation strain of steel ring, cause reduce greatly the service life of steel ring, the steel ring of material generation strain is installed on the vehicle uses, be unfavorable for safe driving; In the fire operation process, need service personnel more, 3 copper ironworkers and 1 tire worker coordinating operation, increased the cost of maintenance, in addition, because tire pressure is higher, cut off in the tire in the process of cover and nut at fire operation, the spark that splashes can splash the surface of tire, cuts off the heat that produces in the process and also can pass to tire by steel ring, causes the air pressure in the high pressure tyre to expand, very easily cause tire to be blasted, have bigger potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of special tool of vehicle tyre three-piece Bolt dismantling, the tire three-piece bolt that this instrument of use can be removed corrosion easily and effectively, kill, improved the efficient of tire three-piece Bolt dismantling, save maintenance cost, avoided potential safety hazard.
For solving the problems of the technologies described above, the special tool of the utility model vehicle tyre three-piece Bolt dismantling is made up of arc, have some hex holes on the described arc at interval, nut coupling on described hexagon hole size and the tire three-piece bolt, the interval location coupling of described some hex hole interval locations and tire three-piece bolt.
Hex hole on the above-mentioned arc is at least two; Above-mentioned arc is to be made by steel plate.
Because the special tool of the utility model vehicle tyre three-piece Bolt dismantling has adopted technique scheme, the i.e. hex hole that mates at the nut that has on the arc on some and the tire three-piece bolt, and the pitch match of the spacing of some hex holes and tire three-piece bolt; When remove a tyre three-piece bolt, two hex holes of arc are placed on the nut of two adjacent tire three-piece bolts, use the tire bolt removing machine to be fixed in the tetragonal position of overlapping in the tire three-piece bolt, start middle cover and nut that tire bolt disassembly machine can be pulled down tire three-piece bolt; Two hex holes of arc are placed on each nut of tire three-piece bolt successively, can pull down the middle cover and the nut of each three-piece bolt successively respectively; According to the different spacing of three-piece bolt on the tyre rim, the spacing of some hex holes on the arc is set, can adapt to the dismounting of the three-piece bolt of different spacing; Therefore the tire three-piece bolt that uses this instrument can remove corrosion easily and effectively, kill has improved the efficient of tire three-piece Bolt dismantling, has saved maintenance cost, has avoided potential safety hazard.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is that self lighting type vehicle rear portion inside and outside shelves tire passes through the bolted scheme drawing of three-piece,
Fig. 2 is the structural representation of this special tool,
Fig. 3 is installed on scheme drawing on the tire three-piece bolt for this special tool.
The specific embodiment
As shown in Figure 2, the special tool of the utility model vehicle tyre three-piece Bolt dismantling is made up of arc 1, have some hex holes 2 on the described arc 1 at interval, nut coupling on the size of described hex hole 2 and the tire three-piece bolt, the interval location coupling of described some hex hole 2 interval locations and tire three-piece bolt.
Hex hole 2 on the above-mentioned arc 1 is at least two; Above-mentioned arc 1 is to be made by steel plate.
As shown in Figure 3, this special tool is at the hex hole 2 that has nut 33 couplings on some and the tire three-piece bolt on the arc 1, and the pitch match of the spacing of some hex holes 2 and tire three-piece bolt; When remove a tyre three-piece bolt, two hex holes 2 of arc 1 are placed on the nut 33 of two adjacent on the overside tyre rim 7 three-piece bolts, use the tire bolt removing machine to be fixed in quadrangle 4 positions of cover 32 in the tire three-piece bolt, start middle cover and nut 33 that tire bolt disassembly machine can be pulled down tire three-piece bolt; Therefore the tire three-piece bolt that uses this instrument can remove corrosion easily and effectively, kill has improved the efficient of tire three-piece Bolt dismantling, has saved maintenance cost, has avoided potential safety hazard.
