The technical scheme that addresses the above problem employing is: torque-shear type bolt quick-release arrangement; Comprise positive stop, Bolt dismantling movable sleeve and Bolt dismantling fixed cover; It is characterized in that described positive stop has the centre bore that is complementary with the torque-shear type bolt; Lateral surface offers storage tank, and the size of described storage tank is greater than the Diagonal Dimension of the clamp nut that cooperates with it, and the periphery of described storage tank also offers stopper slot; Described Bolt dismantling movable sleeve comprises inboard circular coupling box, the cylinder of centre and the wabbler in the outside; The size of the size of described coupling box and cylinder and the clamp nut that cooperates with the torque-shear type bolt is complementary, the wabbler consistent size of described wabbler size and the torque-shear type bolt tail that cooperates; Described Bolt dismantling fixed cover has centre bore, inboard sleeve and the outside and the equivalent nut clamp nut consistent size; The internal diameter of described sleeve is consistent with the outside dimension of coupling box, and said sleeve is provided with and said stopper slot shape and the consistent lower margin of quantity.
The torque-shear type bolt quick-release arrangement of the utility model has following characteristics:
1) simple in structure, commutativity is high
The bolt quick-release arrangement only is made up of three parts, and this three part independently is provided with.When one of them part appearance damage, directly faster these parts get final product, and need not three parts and change together.
2) quick, convenient, safety are installed
Only need Bolt dismantling movable sleeve and nut dismounting movable sleeve are enclosed within on the nut of torque-shear type bolt successively, can accomplish the installation before the dismounting, not only improved efficient, and make operation become very simple, conveniently and safety.
3) be fit to produce in batches
Three components modeling are simple, and less demanding to processing technology, therefore are fit to produce in batches.
As the further improvement of the utility model, the storage tank of described positive stop is a circular groove, and described stopper slot offers on the circumference of circular groove, and quantity is 1-4, preferred 3, and be evenly distributed.

The specific embodiment
See figures.1.and.2 the installation and removal when being applied to the torque-shear type bolt and carrying out torsional moment test with the utility model.Among the figure, backstop 2 is the parts in the torsional moment test device with axial force sensor 3.The torque-shear type bolt quick-release arrangement of the utility model comprises positive stop 4, Bolt dismantling movable sleeve 6 and Bolt dismantling fixed cover 7.
With reference to Fig. 3, Fig. 4 and Fig. 5, described positive stop 4 is the metal derby of oblate column, has the centre bore 401 that is complementary with torque-shear type bolt 1, and lateral surface offers circular storage tank 404; Described storage tank 404 diameters are greater than the Diagonal Dimension of the clamp nut that cooperates with it.Also evenly offer 3 stopper slots 403 on the circumference of storage tank 404.The medial surface 405 of positive stop 4 is the plane, and is provided with a pair of pin-and-hole 402, is used to be connected to axial force sensor 3.
With reference to Fig. 6 and Fig. 7; Described Bolt dismantling movable sleeve 6 comprises inboard circular coupling box 601, the cylinder 602 of centre and the wabbler 603 in the outside; The size of described coupling box 601 and cylinder 602 is complementary with the size of the clamp nut that cooperates 2, the wabbler consistent size of described wabbler 603 sizes and torque-shear type bolt 1 afterbody that cooperates.Described coupling box 601 can be interior hexagonal coupling box or interior 12 jiaos of coupling boxs.
With reference to Fig. 8 and Fig. 9, described Bolt dismantling fixed cover 7 has centre bore 701, inboard circular sleeve 702 and the outside and equivalent nuts 704 clamp nut 5 consistent size, and the internal diameter of described sleeve 702 is consistent with the outside dimension of coupling box 601.Sleeve 702 outsides evenly are provided with 3 lower margins 703, purpose be with front apron on three stopper slots 403 cooperate the circumferential rotation of restriction Bolt dismantling fixed cover 7.
With reference to Figure 10, the installation of torque-shear type bolt and torsional moment test process are following:
1) positive stop 4 is installed in the circular groove of axial force sensor 3 one sides, the side that positive stop 4 has a circular groove 404 is positioned on the axial force sensor 3 positive stop 4 after in pin-and-hole 402, inserting pin outwardly.
2) will be passed the centre bore 401 of backstop 2, axial force sensor 3 and positive stop 4 successively and be placed in one by the side that examination torque-shear type bolt 1 has wabbler, put pad 8, tighten clamp nut 5.
3) electric wrench is placed on the wabbler of clamp nut 5 and torque-shear type bolt 1, the counter-force of the moment of torsion of electric wrench is forward twisted into two parts clamp nut and reverse screwing by the moment of torsion of electric wrench up to the wabbler of torque-shear type bolt 1 afterbody.
After the above-mentioned torsional moment test structure, the unloading process of the utility model torque-shear type bolt quick-release arrangement is following:
4) Bolt dismantling movable sleeve 6 is placed on the clamp nut 5; Again Bolt dismantling fixed cover 7 is placed on the Bolt dismantling movable sleeve 6; The Bolt dismantling fixed cover 7 that rotates in a circumferential direction makes its three lower margins 703 cooperate with three stopper slots 403 on the front apron 4, and is as depicted in figs. 1 and 2.
5) electric wrench is enclosed within on the equivalent nut 704 of Bolt dismantling fixed cover, Bolt dismantling fixed cover 7 has limited circumferential rotation because of being connected with positive stop 4, does not produce circumferential rotation so the top grade of Bolt dismantling fixed cover 7 is imitated nut 704.Wabbler 603 forward rotation under the torsional interaction of electric wrench of nut dismounting movable sleeve afterbody, the clamp nut 5 that promptly drives the torque-shear type bolt rotates toward the direction of unscrewing, and accomplishes the dismounting of torque-shear type bolt.
The foregoing description only is specifying of the installation and removal of the utility model when being applied to the torque-shear type bolt and carrying out torsional moment test.The utility model can be applicable to the job site equally, and need only backstop in the torsional moment test device 2 and axial force sensor 3 be replaced to two connected pieces and get final product, like girder steel and girder steel, perhaps girder steel and steel column, process and the effect wherein dismantled are identical.
What should be understood that is: the foregoing description is just to the explanation of the utility model, rather than to the restriction of the utility model, any utility model that does not exceed in the utility model connotation scope is created, and all falls within the protection domain of the utility model.
