Abstract
Oil-extractor polish-rod device for measuring force, the supporting body having " U " v notch v is provided with block, block coordinates with " U " v notch v and forms mounting hole, wiring board is provided with in the housing that supporting body connects, battery and wireless launcher, the strain post that supporting body is equipped with is pasted with foil gauge, foil gauge, battery and wireless launcher connect with wiring board, strain post is three, three strain posts to penetrate in supporting body and are arranged in around mounting hole, upper at supporting body, lower end is connected with loading plate respectively, lower loading plate, upper loading plate, upper respectively with each strain post of lower loading plate, lower end abutment.In use by upper loading plate and lower loading plate as direct force side, when upper loading plate, lower loading plate bear external force, the upper and lower side of three strain posts forms a carrying plane respectively, can guarantee uniform force, and prevent unbalance loading; In addition, form group bridge by the foil gauge on three strain posts in parallel, measuring accuracy can be made to improve, and anti-overload ability is strengthened.
Description
Technical field
The utility model relates to device for measuring force, specifically a kind of oil-extractor polish-rod device for measuring force.
Background technology
For guaranteeing normal, the safe work of oil pumper, need to carry out dynamometry at work to its polished rod.The basic structure of existing a kind of oil-extractor polish-rod device for measuring force is: supporting body has " U " v notch v, supporting body is provided with block, block coordinates with " U " v notch v and forms mounting hole, strain post supporting body is equipped with, supporting body is connected with housing, be provided with wiring board, battery and wireless launcher in housing, strain post is pasted with foil gauge, and foil gauge, battery and wireless launcher connect with wiring board.The strain post adopted in this device for measuring force be 1-2 only, the shortcoming of existence is: in use strain post directly stressed, time stressed, easy unbalance loading, gently then affects measuring accuracy, heavy then device for measuring force is damaged.
Utility model content
The purpose of this utility model is to provide a kind of oil-extractor polish-rod device for measuring force, and this device for measuring force in use uniform force, offset load resistance is good.
For achieving the above object, the utility model adopts following scheme: oil-extractor polish-rod device for measuring force, supporting body has " U " v notch v, supporting body is provided with block, block coordinates with " U " v notch v and forms mounting hole, supporting body is connected with housing, wiring board is provided with in housing, battery and wireless launcher, strain post supporting body is equipped with, strain post is pasted with foil gauge, foil gauge, battery and wireless launcher connect with wiring board, strain post is three, three strain posts to penetrate in supporting body and are arranged in around mounting hole, upper at supporting body, lower end is connected with loading plate respectively, lower loading plate, upper loading plate, lower loading plate respectively with the upper end of each strain post, lower end abutment.
From such scheme, the utility model adopts three strain posts to be combined with upper loading plate and lower loading plate, in use by upper loading plate and lower loading plate as direct force side, when upper loading plate, lower loading plate bear external force, the upper end of three strain posts, lower end form a carrying plane respectively, can uniform force be guaranteed, and prevent unbalance loading; In addition, form group bridge by the foil gauge on three strain posts in parallel, measuring accuracy can be made to improve, and anti-overload ability is strengthened.
The utility model is rational in infrastructure, and anti-bias load, anti-overload ability strengthen, and measuring accuracy is high, long service life.
Accompanying drawing explanation
