Specific embodiment
It is with reference to the accompanying drawing, right by specific embodiment in order to understand in order to preferably explain the utility model
The utility model is described in detail.
As shown in Figures 1 to 5, the utility model discloses a kind of low clearance annular groove punching load sensors comprising gold
Belong to elastomer 1 and resistance strain gage 2, metal elastomer 1 is cyclic structure, is provided in the middle position of metal elastomer 1 logical
Hole 5.
Ring groove is provided with below metal elastomer 1, the position for corresponding to ring groove above is provided with raised circle
The slot bottom of ring groove is arranged in ring, resistance strain gage 2.
By the way that through-hole 5, the tie-rod and tied arch of cable-stayed bridge cable, suspension bridge is arranged in the middle position of metal elastomer 1
Tie-rod of bridge etc. can be passed through from the intermediate throughholes 5 of sensor.And it by the cooperation of groove and protrusion, can be realized with gold
Belong to elastic bending deflection of 1 groove part of elastomer under load action as measurement object, both meets the punching need of measured object
It wants, and the structure height of sensor can be greatly reduced, compared with traditional cable tension test method, measuring accuracy is high, and is able to achieve
The remote automation of test.
Meanwhile low clearance annular groove punching load sensor also has many advantages, such as big bearing capacity, materials province, easy to process, general
It, can be to these ropes and bar between its anchor head and works for being serially connected with cable-stayed bridge cable, suspension bridge tie-rod or bowstring arch bridge tie-rod
