Technical Field

[0001] The present application relates to the technical field of bolt pulling, and in particular to a failed bolt anti-pulling instrument. Background Art

[0002] During the installation and use of bolts, some technicians use a failed bolt pullout tester to test the bolts to ensure their fixing performance. This tester typically tests the bolt's pullout resistance by applying a pullout force, thereby determining whether the bolt has failed or has the potential to fail.

[0003] In related technologies, the fixing performance of bolts is mainly tested by a failed bolt pullout tester, which is usually composed of components such as a hand pump, a pressure gauge, a high-pressure oil pipe and a hydraulic cylinder.

A support plate 2 is fixedly connected to the lower surface of the anti-pullout instrument body 1, and the anti-pullout instrument body 1 and the support plate 2 are fixed by bolts, so that personnel can disassemble the anti-pullout instrument body 1 and the support plate 2 as needed. The support plate 2 provided can play a certain supporting role in the anti-pullout instrument body 1. At the same time, when the anti-pullout instrument body 1 is placed on a flat surface for use, the support plate 2 can also increase the contact area with the flat surface, thereby enhancing the stability of the anti-pullout instrument body 1 when placed in use. The two sides of the support plate 2 are respectively equipped with stabilizing support bars 3 through multiple connecting parts 4. The stabilizing support bars 3 set can be located on the side away from the support plate 2 for support under the cooperation control of the connecting parts 4 and the first spring 6, and the support plate 2 and the stabilizing support bar 3 also have a certain weight. Therefore, through the cooperation of the stabilizing support bar 3 and the support plate 2, the stability of the support of the anti-pullout instrument body 1 can be further improved to prevent the anti-pullout instrument body 1 from being unstable when personnel operate it, thereby making it more convenient for personnel to operate. At the same time, it can also improve the efficiency of bolt detection, making this application more conducive to practical use. It should be further explained that anti-slip pads are evenly fixed on the lower surfaces of the support plate 2 and the stabilizing support bar 3, which can play a certain anti-slip effect when used in this application.

[0033] In a further preferred embodiment of the present invention, Figure 1 As shown, the anti-pullout instrument body 1 includes a hand pump 101 fixedly connected to the upper surface of the support plate 2, a pressure gauge 102 is fixedly connected to the hand pump 101, one end of the hand pump 101 is fixedly connected to a high-pressure oil pipe 103, and the end of the high-pressure oil pipe 103 away from the hand pump 101 is fixedly connected to a hydraulic cylinder 104.

[0034] In this embodiment, the user presses the hand pump 101 to cooperate with the hydraulic cylinder 104 through the high-pressure oil pipe 103 to detect the fixing performance of the bolt, and the hand pump 101 and the support plate 2 are connected by bolts, so that the hand pump 101 can be supported by the support plate 2.

[0035] In a further preferred embodiment of the present invention, Figure 1 、 Figure 2 and Figure 3As shown, the support plate 2 includes a rectangular plate 201 located on the lower surface of the hand pump 101, and a plurality of threaded mounting holes 202 are evenly opened on the upper surface of the rectangular plate 201.

The end of each connecting member 4 away from the stabilizing support bar 3 is correspondingly located inside each first storage groove 203, and each first spring 6 is correspondingly arranged inside each first storage groove 203.

[0036] In this embodiment, the hand pump 101 can be fixed on the rectangular plate 201 by cooperating with the threaded mounting hole 202 and the bolt, so that the hand pump 101 can be supported by the rectangular plate 201, and the first storage groove 203 can limit the installation position of one end of the connecting member 4 and the first spring 6.

At the same time, the position of the stabilizing support bar 3 can also be limited by the connecting bar 401.

When a person presses the pressing head 804, the connecting plate 801 can be controlled to move downward. When the connecting plate 801 moves downward, the second spring 803 can be squeezed to contract, and at the same time, the triangular snap-fit ​​block 802 can be driven to move downward. The downward movement of the triangular snap-fit ​​block 802 can release the engagement with the snap-fit ​​groove 9, so that the stabilizing support bar 3 can be popped outward for use under the elastic force of the first spring 6.

[0043] In a further preferred embodiment of the present invention, Figure 4 As shown, the lower surface of the connecting plate 801 is evenly fixed with a limiting rod 10, and the interior of the stable support bar 3 is evenly provided with a limiting hole 5 connected to the second storage slot 7, and the end of the limiting rod 10 away from the stable support bar 3 is located inside the limiting hole 5.
