Abstract
A kind of elevator belt hopper Special bolt wrench, comprise sleeve, the head of described sleeve is provided with and adapts with the nut of described elevator belt hopper bolt and can hold the cavity of described nut, the inside of described cavity is provided with magnetic adsorbing block, distance between described magnetic adsorbing block surface and described socket end actinal surface is greater than the height of described nut, and the inwall of described cavity being provided with the limited block of at least one projection, described limited block is in order to the claw inside spacing described nut.Although the present invention's structure is simple, the screw-in that can realize steel wire elevator belt hopper bolt is installed, and the screw thread avoiding bolt is damaged, improves installation strength.
Description
Technical field
The present invention relates to elevator belt erecting tools, be specifically related to a kind of elevator belt hopper Special bolt wrench.
Background technology
At present, steel wire elevator belt, because it has high strength, excellent lear energy, is widely used in fields such as coal, mine, harbour, metallurgy, electric power, chemical industry, and is generally used for long distance, large conveying quantity, high-speed convey materials.
Steel wire elevator belt generally needs to carry out installation with hopper in use and combines, and installation combination general at present adopts bolt, wherein the structure of bolt as shown in Figure 1, it comprises a discoid nut, stud is smooth section in the nearly section near nut, section far away is then thread segment, and thread segment is provided with nut.In use, by stud through steel wire elevator belt, and it is fastening to utilize nut to carry out.Occurring to prevent mounted bolt rotating, being provided with the claw of several projections in the inner side of nut, thus steel wire elevator belt can be firmly grasped.
At present, the mounting means of bolt is all directly utilize external force to beat nut, stud is forced through steel wire elevator belt.But owing to being distributed with crisscross steel wire in steel wire elevator belt, when adopting above-mentioned mounting means, being easy to the thread damage of stud thread segment, causing occurring obscission during later-stage utilization fastening nuts, and the efficiency of installing is very low.
For a long time, those skilled in the art is also always at exploration one more reasonably mounting means, but the nut due to bolt is discoid, cannot utilize traditional spanner or other clamp, this also becomes the long-standing technical barrier in this area at all.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of elevator belt hopper Special bolt wrench, thus eliminates defect in above-mentioned background technology.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of elevator belt hopper Special bolt wrench, comprise sleeve, the head of described sleeve is provided with and adapts with the nut of described elevator belt hopper bolt and can hold the cavity of described nut,
The inside of described cavity is provided with magnetic adsorbing block,
Distance between described magnetic adsorbing block surface and described socket end actinal surface is greater than the height of described nut,
And the inwall of described cavity being provided with the limited block of at least one projection, described limited block is in order to the claw inside spacing described nut.
Improve as one, described magnetic adsorbing block is permanent magnet.
Improve as one, described magnetic adsorbing block is electromagnet.
Improve as one, the lateral surface of described limited block flushes with described socket end actinal surface.
Improve as one, described limited block is one.
Improve as one, described limited block is two, and is symmetrically distributed on the inwall of described cavity.
In addition, the afterbody of described sleeve is provided with connection handle, in order to connect electric drill or other electric tool.
The nut of elevator belt hopper bolt in use, is put into the cavity of sleeve head, is utilized magnetic adsorbing block to be adsorbed by nut by the present invention; Then be connected on electric drill by connection handle, utilize electric drill to be pierced by bolt in steel wire elevator belt, when rotating, protruding limited block can be spacing by claw, effectively avoids the rotation of bolt, thus complete the work of piercing smoothly.
Because steel wire elevator belt hopper bolt is more special, especially have employed discoid nut, and it is very rare to have discoid nut and bolt in reality, even if screw, its discoid nut is also offer cross pattern or a word line, screwdriver is utilized to install, larger with steel wire elevator belt hopper bolt difference; And other have discoid nut securing member, such as rivets etc., its mounting means mounting means traditional with steel wire elevator belt hopper bolt is the same, is all to adopt brute force to knock to install.Those skilled in the art are difficult to from above-mentioned situation, obtain technology enlightenment, also because discoid nut cannot easy clamping or clamping as traditional hexagonal (hexagon)nut, therefore, those skilled in the art's inertia have employed the most frequently used, be also the mounting means that the most basic direct brute force is beaten, do not think for a long time to change, this also causes this problem to become the long-standing technical barrier in this area.And the mounting means occurring revolutionizing brute force for a long time and beat of the present invention, although the present invention's structure is very simple, but the claw that make use of cleverly inside nut, arranging limited block carries out spacing, prevent screws, the screw-in achieving bolt is installed, and the screw thread of bolt can be avoided to be damaged by the steel wire in steel wire elevator belt, solve long-standing technical barrier.
Owing to have employed technique scheme, the invention has the beneficial effects as follows:
1, the present invention is provided with magnetic adsorbing block in the cavity of sleeve head, can be placed wherein by nut easily and can not drop, improve the convenience of operation.
2, the present invention is provided with the limited block of at least one projection on the cavity inner wall of sleeve head, this limited block is in order to the claw inside spacing described nut, prevent the rotation of bolt thus complete the work of piercing smoothly, change external force directly knocks bolt to be made it to be forced through steel wire elevator belt into bolt being screwed in steel wire elevator belt by electric drill or other instruments, force efficiency is not only economized high during screw-in, and can effectively avoid the screw thread of bolt damaged, thus improve installation strength.
3, magnetic adsorbing block of the present invention is permanent magnet, also can adopt electromagnet, and the lateral surface of limited block flushes with described socket end actinal surface, and the surface of not easily scratching steel wire elevator belt, can ensure the built-in length of bolt so when mounted.
In a word, although the present invention's structure is simple, the screw-in that can realize steel wire elevator belt hopper bolt is installed, and the screw thread avoiding bolt is damaged, improves installation strength.
