Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples

Referring to fig. 1-3, a pipe fitting construction bolt connects anchor clamps for stretching resistance detection, including slide 1, the welding of one side of slide 1 has backup pad 2, sliding connection has slide 3 on slide 1, it remains to press from both sides bolt 4 to connect on the slide, it waits to be connected with the fixed fixing device who waits to press from both sides bolt 4 on the bolt 4 to press from both sides, be equipped with scale 8 on slide 1, scale 8 begins the equidistance from the position of backup pad 2 and is equipped with the scale, on slide 1, because the existence of scale 8, make can be accurate to the position of screw thread section when carrying out the tensile detection to the bolt.

Fixing device includes rotor plate 5, rotor plate 5 is connected and is being treated one side that slide 3 was kept away from to press from both sides bolt 4, rotor plate 5 with treat that to press from both sides 4 threaded connection of bolt, rotor plate 5's bottom clearance fit has slider 7, the welding has fixed plate 13 on slider 7, fixed plate 13's center is rotated through the bearing and is connected with sleeve 6, 6 fixed connection rotor plate 5 of sleeve, and prescribe a limit to the turned position through fixed plate 13, make when sleeve 6 is rotatory in fixed plate 13, can drive rotor plate 5 rotatory, thereby radial movement on the screw thread section.

The one end welding that fixed plate 13 was kept away from to sleeve 6 is on rotor plate 5, the spread groove has been seted up on slider 7, the bottom and the spread groove clearance fit of rotor plate 5, rotor plate 5 is connected with pulling force machine 9, pulling force machine 9 is connected fixedly with external ground, pulling force machine 9 passes through the bearing to rotor plate 5 and is connected, and to rotor plate 5 output pulling force, realize the pulling force to treating clamp bolt 4 through the pulling force to rotor plate 5, thereby provide the pulling force requirement of tensile detection, treat that there are nut 41 and screw thread part on clamp bolt 4 respectively, slide 3 has a plurality of balls 12 near the one side welding of nut 41, a plurality of balls 12 annular sets up the outer lane at the screw thread part, the inner wall of slide 3 is run through to the screw thread part, screw thread part and slide 3 clearance fit, make ball 12 in the part closely contradict with nut 41 and will treat clamp bolt 4 and fix. Meanwhile, the sliding plate 3 plays a role in limiting, so that the threaded part of the bolt 4 to be clamped is always kept in a horizontal state.

Slide 3's top is run through and is equipped with screw rod 10, screw rod 10 runs through the inner wall of backup pad 2, slide 3's one end fixedly connected with knob 11 is kept away from in backup pad 2 to screw rod 10, screw rod 10's polished rod part passes through the bearing with backup pad 2 and rotates and be connected, sleeve 6 has hand rocker 14 in the welding of one side outside fixed plate 13, sleeve 6's inner wall and screw thread part clearance fit make slide 3 remove in threaded connection in the rotation of knob 11, thereby play fixed or the effect that breaks away from.

When the utility model is used, firstly the sliding plate 3 is moved to the left by the rotating knob 11 until the ball 12 is fully collided with the nut 41 to fix the sliding plate, the advantage of doing so is that the screw thread part is not needed to be collided when fixing the bolt 4 to be clamped, the screw thread deformation is avoided under the larger pressure state, thereby the screw thread is damaged before the detection is opened, the inaccuracy of the detection structure is caused, simultaneously the hand lever 14 is rotated, because the hand lever 14 is fixedly connected with the sleeve 6, the sleeve 6 and the rotating plate 5 are welded to ensure that the rotating knob can make the rotating plate 5 screwed into the screw thread of the bolt 4 to be clamped, because the rotating plate 5 is in threaded connection with the bolt 4 to be clamped, the rotating plate 14 is continuously rotated to make the rotating plate 5 approach to the nut 41, at the moment, the bottom of the rotating plate 5 is superposed with the groove of the scale 8, the fixing position of the rotating plate 5 can be observed, make tensile machine 9 carry out the pulling force operation to rotor plate 5, also mean that tensile machine 9 treats clamp bolt 4 and carries out the pulling force effect, detect for the tensile and provide power, and after a testing result, can continue to detect the position through rotating rotor plate 5 adjustment next time, conveniently carry out the contrast experiment, also can detect out whether the screw thread intensity of specific a particular body section is enough through many times of contrast experiments, improved detection efficiency, also got rid of the interference.

Above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the design of the present invention, equivalent replacement or change should be covered within the protection scope of the present invention.
