Abstract
The invention belongs to the technical field of tools and clamps and discloses an anti-shaft-rotating wrench which comprises a monkey wrench with two clamping plates in left-right symmetry. One ends of the clamping plates are hinged with each other while the other ends of the same are hinged with a movable clamping mouth of the monkey wrench respectively through two connecting plates in left-right symmetry and hinged with the other ends, and a fixed clamping mouth of the monkey wrench is hinged with a jacking rod. The anti-shaft-rotating wrench is simple in structure, low in manufacturing cost and capable of applying shearing force and jacking force to bolts, so that shaft rotating during screwing of the bolts is effectively avoided.
Description
Technical field
The present invention 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.
Summary of the invention
The technical problem to be solved in the present invention 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, the technical solution used in the present invention 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 present invention 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
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present invention;
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, the present invention stirs 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 present invention 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 present invention 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 present invention 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 present invention 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.
