Abstract
The utility model relates to a special tool for a screw-in double-head screw stud, which comprises two clamping bars rotationally connected. Two fixture blocks are arranged on the two clamping bars. The inner side of the fixture block is a cambered surface on which a gibbous structure is arranged. Two movable blocks are arranged between the two fixture blocks, connected with the fixture blocks by adjusting screws, and positioned at the top ends of the adjusting screws. Because the inner sides of the two fixture blocks or the movable blocks are the cambered surfaces on which internal screw threads or convex teeth arrayed in a spiral line are arranged, and the specification and the model of a screw thread grip formed by the two fixture blocks or the movable blocks are the same as those of the screw thread of the screw-in double-head screw stud to be assembled or disassembled, when the screw-in double-head screw stud is installed or disassembled, the two fixture blocks or the movable blocks directly clamp the screw thread part of the non-screw-in end of the screw-in double-head screw stud, the surface where the two fixture blocks or the movable blocks are in contact with the screw-in double-head screw stud is a screw thread surface, thus the screw-in double-head screw stud can be quickly and easily assembled or disassembled, and the screw thread surface of the screw-in double-head screw stud can not be damaged.
Description
Technical field
The utility model relates to handling instrument, the specific purpose tool of particularly a kind of installation, dismounting screwing in double-ended stud.
Background technology
Chemical enterprise is a flow type enterprise, chemical material between each production equipment of enterprise extensively adopts pipeline to carry, design has pipe fittings such as valve, flange on the pipeline, the pipeline of access device connects with generally adopting screwed flange being connected of apparatus body, especially high-tension apparatus, the import and export of part high pressure valve connect with also adopting screwed flange being connected of its pipeline.It is earlier screwed flange to be installed on the threaded pipeline of car that screwed flange connects, and connects binding thread flange and equipment or high pressure valve with being screwed into stud again.Every cover is screwed into stud and is made up of a screwing in double-ended stud and a nut.During installation, earlier with in the screw on the screw terminal screw-in apparatus body of screwing in double-ended stud, high pressure flange is installed then usually, is gone up jack panel at last again together with pipe fittings such as high-voltage tubes.The screwing in double-ended stud of standard does not design the boss of common wrench clamping, generally directly screwing in double-ended stud is screwed in screw with hand by assembling, service worker, so unusual effort, operating efficiency is low again, particularly cooperates when tight more obvious with screw when screwing in double-ended stud.For addressing this problem, often the method that adopts has two kinds.A kind of method is: earlier the non-screw terminal of screwing in double-ended stud is loaded onto two nuts, piece together these two nuts tight, pull one of them nut with spanner, thereby screwing in double-ended stud is screwed in the screw on the apparatus body, again this two nut is unloaded after being screwed to the position.The shortcoming of this method is comparatively to bother, inefficiency; Another kind method is: block screwing in double-ended stud with pipe grippers, again screwing in double-ended stud is screwed in the screw of apparatus body, but the shortcoming of this method is, no matter be clipped on the polished rod of studs or on the screw thread, all occur easily skidding and damages the phenomenon on studs surface.Therefore, be necessary to design a kind of specific purpose tool, improve existing method, so that Fast Installation or dismounting screwing in double-ended stud.
The utility model content
In order to overcome the deficiency in the background technology, the utility model provide a kind of can Fast Installation or the screwing in double-ended stud of dismounting all size, can't damage the specific purpose tool of screwing in double-ended stud thread surface.
The technical scheme that its technical problem that solves the utility model adopts: a kind of special-purpose tool for screwing in double-ended stud, comprise two clamping bars that are rotatably connected, have fixture block on two clamping bars.
The inboard of described fixture block is an arcwall face, has the convex structure on the arcwall face.
Described convex structure is internal thread or the double wedge arranged of line in the shape of a spiral.
Be provided with two movable blocks between described two fixture blocks, movable block is connected with fixture block by adjustment screw, and is positioned at the top of adjustment screw.
The inboard of described movable block is an arcwall face, has the convex structure on the arcwall face.
Described convex structure is internal thread or the double wedge arranged of line in the shape of a spiral.
Described two clamping bars connect by hinges.
The beneficial effects of the utility model: because the inboard of two fixture blocks or two movable blocks is an arcwall face, have internal thread or the double wedge arranged of line in the shape of a spiral on the arcwall face, the specifications and models of the screw clamp mouth that two fixture blocks or two movable blocks are formed are identical with the specifications and models of the screw thread of the screwing in double-ended stud of to be installed or dismounting, during the installation or removal screwing in double-ended stud, the threaded portion of the non-screw terminal of two fixture blocks or two movable block clamping screwing in double-ended stud, the contact-making surface of two fixture blocks or two movable blocks and screwing in double-ended stud is a thread surface, contact area is big, very little clamping force can produce bigger frictional force to the screw thread position of screwing in double-ended stud so that transmit torsional moment, so can the very fast screwing in double-ended stud of installation or removal very like a cork, operating efficiency is very high, and can not damage the thread surface of screwing in double-ended stud.This tool construction is simple, and is easy to use, easy to utilize.

The specific embodiment
Embodiment 1
As shown in Figure 1 and Figure 2, instrument comprises that the end of two clamping bars, 1, two clamping bar 1 connects by hinge 5.Position near hinge on two clamping bars 1 is provided with arc fixture block 2, have screwed hole on the two arc fixture blocks 2, screw 4 is housed in the screwed hole, the end of screw 4 is connected with arc movable block 3, the inboard of two arc movable blocks 3 has internal thread, constitutes screw clamp mouth 6 between the two arc movable blocks 3.Can regulate distance between the two arc movable blocks 3 by rotating two screws 4, the size that can regulate screw clamp mouth 6 by the two arc movable blocks 3 of changing different size is with the dress of the screwing in double-ended stud that is applicable to various different sizes, tear open.
As shown in Figure 3, Figure 4, instrument comprises that the end of two clamping bars, 1, two clamping bar 1 has arc fixture block 2, two clamping bars and connects by hinge 5 at the position near fixture block.Have screwed hole on the two arc fixture blocks 2, screw 4 is housed in the screwed hole, the inboard that the end of screw 4 is connected with arc movable block 3, two arc movable blocks 3 has internal thread, constitutes screw clamp mouth 6 between the two arc movable blocks 3.Can regulate distance between the two arc movable blocks 3 by rotating two screws 4, the size that can regulate screw clamp mouth 6 by the two arc movable blocks 3 of changing different size is with the dress of the screwing in double-ended stud that is applicable to various different sizes, tear open.
