Description

Check guest net tensile testing anchor clamps

Technical Field

The utility model relates to a check out test set technical field, more specifically say, relate to a check guest net tensile testing anchor clamps.

Background

Check guest net generally is metal mesh structure, extensively be used for traffic, water conservancy, soil and water conservation and civil engineering project in, in the testing process to check guest net, need detect the tensile strength of check guest net, a anchor clamps are held respectively to the ordinary left and right hands of staff among the prior art, hook the check guest net both ends of single model through the couple on the anchor clamps, combine electronic detection equipment, carry out tensile test to check guest net, in this kind of experiment of this institute, check guest net testing object usually has M6 (adjacent hole interval is 60mm), M8 (adjacent hole interval is 80mm), three kinds of models of M10 (adjacent hole interval is 100mm), adopt traditional tensile test to press from both sides and have the following weak point: 1. the existing clamp needs to be replaced by different clamps for testing different mesh sizes of the check guest, the replacement is time-consuming and labor-consuming, and meanwhile, the loss of hook materials is caused; 2. the hook is adopted for fixing, the fixing effect of the check net is not ideal enough, the sliding condition possibly occurs in the test process, and the precision of the tensile test is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a check guest net tensile test anchor clamps, the device can be applicable to the check guest net tensile test of multiple specification, adopts screw nut or pin fixed, and check guest net is difficult to slide in the test process, has improved test data's accuracy greatly.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

the utility model provides a check guest net tensile test anchor clamps, includes anchor clamps A and anchor clamps B, anchor clamps A and anchor clamps B be slice bilayer structure and the structure symmetry is the same, anchor clamps A both sides below respectively be equipped with a mounting hole, anchor clamps A slice bilayer structure pass the mounting hole through the bolt and fix together, anchor clamps A surface be equipped with a plurality of groups check guest net fixed through holes, every group check guest net fixed through hole corresponds the check guest hole interval size of single model respectively, anchor clamps A and anchor clamps B respectively inside press from both sides the both ends that check guest net corresponds and pass through screw nut or pin fixed through hole and carry out spacing fixedly to the check guest net that inside pressed from both sides the dress, anchor clamps A slice bilayer structure top one side welding have connecting screw.

Further, the length of the clamp A and the clamp B is 1100-1150 mm.

Furthermore, the connecting bolt is fixed with the output end of the laboratory universal tensile testing machine.

Furthermore, the number of the groups of the check net fixing through holes is set according to specific test requirements.

Compared with the prior art, the utility model has the advantages that:

the utility model discloses anchor clamps simple structure, simple to operate is applicable to different types of check guest net test, through screw nut or pin etc. at the inside fixed check guest net of anchor clamps for check guest net is difficult to slide, has improved test data's accuracy greatly.

FIG. 1 is a schematic view of the overall structure of the present invention;

in the figure: 1. a clamp A; 2. a clamp B; 3. mounting holes; 4. a fixing through hole; 5. and connecting the screw rod.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the utility model easy to understand and understand, the utility model is further explained by combining with the specific figures.

As shown in figure 1, a check net tensile test fixture comprises a fixture A1 and a fixture B2, wherein the fixture A1 and the fixture B2 are both of a sheet-shaped double-layer structure and have the same structural symmetry, a mounting hole 3 is respectively arranged below two sides of the fixture A1, the sheet-shaped double-layer structure of the fixture A1 penetrates through the mounting hole 3 through a bolt to be fixed together, a plurality of groups of check net fixing through holes 4 are arranged on the surface of the fixture A1, each group of check net fixing through holes 4 respectively correspond to the check net pitch size of a single model, three groups of the fixing through holes 4 (the number of the fixing through holes is M6 and eight, M8 and M10 are ten) are arranged in figure 1 according to a detected object, the three types of the fixing through holes 4 (the number of the M6 and the M8 respectively correspond to the adjacent hole pitch of the M6 and are 60mm), the adjacent hole pitch of the M8 and the adjacent hole pitch is 80mm, the M10 (the adjacent hole pitch is 100mm), the two types of the fixture A1 and the fixture B2 The guest net carries out spacing fixed, and the welding of anchor clamps A1 slice bilayer structure top one side has connecting screw 5, and anchor clamps A1 and anchor clamps B2 length are 1100mm, and connecting bolt 5 is fixed with the universal tensile testing machine output in laboratory, and 4 groups of number of check guest net fixed through-hole set up according to concrete experimental needs.

In practical use, if the M6 check net is detected, the hole spacing is 60mm, one end of the check net is placed inside the double-layer structure of the clamp A1, the meshes of the check net are aligned to the fixing through holes 4 with corresponding spacing, the check net is fixed through screws, nuts or pins, then bolts penetrate through the mounting holes 3 to fix the clamp A1 with the double-layer sheet structure together to clamp and fix the check net, the fixing method of the clamp B2 is the same, and finally the clamp A1 and the clamp B2 which are fixed with the check net are connected with a universal tensile testing machine through the connecting screw rods 5 to detect the tensile parameters.

The basic principles and main features of the invention and the advantages of the invention have been shown and described above.
