Abstract
The utility model provides a wrench which comprises an arc-shaped wrench body. The arc-shaped wrench body is provided with a working end and a holding portion, wherein an equilateral polygon through-hole is arranged on the working end. Provided is the wrench, a wrench body of the wrench is the arc-shaped wrench body. Compared with a holding portion of a common straight shank wrench, the holding portion of the wrench is closer to a pipe wall of a pipeline system by adopting an arc-shaped structure. Therefore, in the condition of the same distance of the pipeline system to a roadway side portion, a single rotational angle of the wrench is greater than an angle of the straight shank wrench. Therefore, in the same using condition, bolt rotational times of using the wrench to fix and dismantle a flange plate are less and working efficiency can be improved.
Description
Technical field
The utility model relates to the hardware ﹠ tools technology, relates in particular to a kind of spanner.
Background technology
In the industry of colliery, multiple pipe-line system is installed under the mine, the pipe assembly in each pipe-line system generally adopts ring flange to connect.Install, when removing pipe-line system, fastening, the dismounting of the flange plate bolt operation that is absolutely necessary.Because construction environment under the mine determines, each pipe-line system is maked somebody a mere figurehead often or is installed near tunnel section of side, therefore, to the pipeline that some diameters are large, pressure rating is higher, its near the flange plate bolt of section of side because narrow space, as shown in Figure 1, the rotational angle a of common straight spanner 5 is less so that flange plate bolt 6 fastening, when dismounting efficient lower.
The utility model content
The utility model provides a kind of spanner, is used for efficient fastening near the pipe-line system flange plate bolt of tunnel section of side under the raising mine, dismounting.
The utility model provides a kind of spanner, comprises the arc wrench body, and described arc wrench body has working end and grip part, and described working end is provided with the regular polygon through hole.
Aforesaid spanner, wherein, described regular polygon through hole is the dodecagon hole.
Aforesaid spanner, wherein, described arc wrench body is curved plate.
Aforesaid spanner, wherein, the thickness of described working end is greater than the thickness of described grip part.
Aforesaid spanner, wherein, the end that described arc wrench body arranges the regular polygon through hole is curved end, the axis coaxle of the axis of described curved end and described regular polygon through hole.
Aforesaid spanner, wherein, the other end of described arc wrench body is provided with through hole.
The spanner that the utility model provides, its wrench body is the arc wrench body, adopt arcuate structure so that the position that the position that this spanner is held is held with respect to common straight spanner can be relatively near the tube wall of pipe-line system, like this, in the situation that pipe-line system is identical apart from tunnel section of side distance, the angle of this spanner single revolution is greater than the angle of straight spanner, therefore, under identical operating position, adopt the number of times that this spanner is fastening, the dismounting flange plate bolt rotates less, improved operating efficiency.
Description of drawings
Fig. 1 is existing straight spanner working state figure;
Fig. 2 is the structural representation of the utility model spanner embodiment;
Fig. 3 is the utility model spanner working state figure.
The specific embodiment
Fig. 2 is the structural representation of the utility model spanner embodiment; As shown in Figure 2, the embodiment of the utility model spanner, this spanner comprises arc wrench body 1, and arc wrench body 1 has working end and grip part, and the working end is provided with regular polygon through hole 3.
The spanner of such scheme, its wrench body is arc wrench body 1, adopt arcuate structure so that the position that the position that this spanner is held is held with respect to common straight spanner can be relatively near the tube wall of pipe-line system, like this, in the situation that pipe-line system is identical apart from tunnel section of side distance, the angle of this spanner single revolution is greater than the angle of straight spanner, therefore, under identical operating position, adopt the number of times that this spanner is fastening, the dismounting flange plate bolt rotates less, improved operating efficiency.
In actual applications, regular polygon through hole 3 is the dodecagon hole.Adopt the dodecagon hole can be eaily hexagon-head or the nut of bolt to be sticked in the dodecagon hole.Certainly, the regular polygon through hole also can be the regular polygon through hole of other limit number.
For the ease of processing, arc wrench body 1 is curved plate, and this curved plate can be formed by block plate cutting.
In order more firmly to block nut, bolt, and the deadweight of this spanner of reduce, then can adopt the thickness of working end greater than the thickness of grip part.
In order to prevent in this spanner rotation process, its end clamping stagnation then is set to curved end 4, the axis coaxle of the axis of curved end 4 and regular polygon through hole 3 in the end that arc wrench body 1 arranges regular polygon through hole 3 on the tube wall of pipe-line system.Like this, when this spanner blocked bolt or nut and rotates, it arranged the end of regular polygon through hole 3 and the distance between the tube wall remains unchanged, and therefore avoids occurring occurring with tube wall the problem of clamping stagnation.
The other end in arc wrench body 1 is provided with through hole 2, an end of also namely holding is provided with through hole 2, when work high above the ground, this through hole 2 stays rope to use as work high above the ground, be appreciated that, fasten in this through hole 2 with rope, then this spanner is lifted to work high above the ground personnel place, for the work high above the ground librarian use.
This spanner in use, as shown in Figure 3, the regular polygon through hole blocks flange plate bolt 7, and the outer tube wall of pipeline 8 is pressed close at the arc-shaped bend position of arc wrench body 1, and the radian of arc wrench body 1 and pipeline 8 circumference radians approach, like this, under identical working environment, the existing straight spanner of the rotating angle b of this spanner single wants large, therefore, adopt the number of times that this spanner is fastening, dismounting flange plate bolt 7 rotates less, operating efficiency is higher.
It should be noted that at last: above each embodiment is not intended to limit only in order to the technical solution of the utility model to be described; Although with reference to aforementioned each embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
