Abstract
The utility model discloses an anti-pivoting wrench and relates to the technical field of clamping apparatuses. The anti-pivoting wrench comprises a shifting wrench. Two clamping plates are arranged in a laterally symmetrical mode, one end of one clamping plate is hinged to one end of the other clamping plate, the other ends of the clamping plates are hinged to a movable clamping opening of the shifting wrench through two laterally symmetrical connection plates hinged to the clamping plates, and a fixed clamping opening of the shifting wrench is hinged to an ejecting rod. The anti-pivoting wrench is simple in structure, low in manufacturing cost and capable of exerting shearing force and ejecting force on a bolt and effectively prevents pivoting of the bolt during bolt screwing.
Description
Technical field
The utility model relates to the clamping apparatus technical field.
Background technology
Increasing along with the continuous expansion electric power pylon of electrical network scale, the bolted of a large amount of uses of connecting bolt and iron tower tower head small space seems extremely important, especially in recent years the iron tower bolt gets loose, and the accident of falling the tower of causing is even generation, and iron tower tower head small space bolt can not be effectively fastening.Fastened tools commonly used at present is 250-30,300-50 roll adjustment spanners, in the crisscross small space of iron tower tower material, can not use, the bolt rotating shaft takes place in bolt in fastening, therefore can not effectively bolt be tightened, the slip-off preventing effect is relatively poor, and these problems directly influence the safety operation level of electric power pylon.
The utility model content
The technical problems to be solved in the utility model provides a kind of anti-axle commentaries on classics spanner, and simple in structure, cost of manufacture is low, can apply shearing force and top power to bolt, has effectively avoided bolt that axle takes place in bolt screws and has changeed.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of anti-axle commentaries on classics spanner comprises shfting wrench; 2 left-right symmetry clamping plate are arranged, and an end is twisted together mutually, and the other end is twisted together mutually by 2 moving dops with its symmetrical connecting plate that is twisted together and shfting wrench respectively, and the dop of deciding of shfting wrench is twisted together mutually with push rod.
The interior survey of preferred 2 left-right symmetry clamping plate is provided with the arc non slip surface.
Also be provided with the folding angle adjusting mechanism of left-right symmetry clamping plate.
Angle adjusting mechanism is: be provided with the spacing adjusting bolt of symmetrical connecting plate in the place of being twisted together mutually at moving dop.
The beneficial effect that adopts technique scheme to produce is: the anti-axle of the utility model commentaries on classics spanner, simple in structure, cost of manufacture is low, can apply shearing force and top power to bolt, has effectively avoided bolt that axle takes place in bolt screws and has changeed.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
1 is shfting wrench, and 2 is the left-right symmetry clamping plate, and 3 is symmetrical connecting plate, and 4 for to decide dop, and 5 is push rod, and 6 is the arc non slip surface, and 7 are spacing adjusting bolt.
The specific embodiment
A kind of anti-axle commentaries on classics spanner comprises shfting wrench 1; Have 2 left-right symmetry clamping plate 2, one ends to be twisted together mutually, the other end is twisted together mutually by 2 moving dops with its symmetrical connecting plate 3 that is twisted together and shfting wrench 1 respectively, and the dop 4 of deciding of shfting wrench 1 is twisted together mutually with push rod 5;
The interior survey of 2 left-right symmetry clamping plate 2 is provided with arc non slip surface 6;
Also be provided with the folding angle adjusting mechanism of left-right symmetry clamping plate 2;
The folding angle adjusting mechanism is: be provided with the spacing adjusting bolt 7 of symmetrical connecting plate 3 in the place of being twisted together mutually at moving dop.
When using, stirs the utility model the thumb wheel of shfting wrench, making dop drive symmetrical connecting plate moves, upwards that spanner is cocked, moving dop drives symmetrical connecting plate and is inclined upwardly, bolt is put into the groove that arc non slip surface that 2 left-right symmetry clamping plate survey forms, get final product with the push rod puller bolt.
The principle of anti-axle commentaries on classics spanner, be bolt install the later stage fastening in arc non slip surface by 2 left-right symmetry clamping plate inboards give bolt and apply shearing force, give bolt by push rod and apply top thick stick power; Making bolt that axle can not take place in precession changes, preferably fastening bolt.Can satisfy the various operating mode instructions for uses under the iron tower bolted according to special tower equipment structure, be applicable to that the tower structure is intensive, the bolt shaft commentaries on classics is difficult for stuck bolted.
The anti-axle of the utility model commentaries on classics spanner has solved international diameter 12,14,16 and 18 standard bolt is being installed the problem that axis changes, high-intensity shearing force and top thick stick power, can effectively prevent the bolt shaft commentaries on classics, bolted can satisfy transmission line of electricity fully to each performance requirement of tower equipment structure.
The utility model can also solve the bolted problem on the tower equipment structure, has improved tower material resistance to shock greatly.
This instrument has effectively solved the unsettled fastening problem of tower material connecting bolt nut, and the operation that operating personnel's side is in the past lain prone on the tower face changes the seat operation of squatting into, has improved operating personnel's operating environment.
The utility model moves dop and decides dop and adopt No. 48 high-speed tool steels to make, and material can require the suitable material of choice according to special structural behaviour, and to satisfy the intensity to bolt, rigidity and fatigue-resistance characteristics are given full play to the high advantage of intensity.
The anti-axle of the utility model commentaries on classics spanner is applicable to the bolted that transmission of electricity, distribution, framework, bridge and iron and steel are built, and has bigger economic benefit and vast market prospect.
