The self-balancing auxiliary assembly reduces labor intensity of inspection by means of lightening self weight of the ring gauge and self-balancing weight, improves inspection convenience, and reduces damage of the ring gauge to threads to a certain degree.
Description
Technical field
The utility model relates to measuring equipment, and particularly a kind of self-balance type servicing unit that is applicable to screw at the ring gauge circumferencial direction is applicable to the ring gauge of the relevant screw of heavy caliber oil well pipe at the ring gauge circumferencial direction.
Background technology
For bigbore tubing and casing (external diameter is 95/8 " above specification), check closely size and the weight apart from the ring gauge of usefulness is all bigger, and wherein the heaviest 20 " ring gauge weight reaches 75 kilograms.Ceng Youyi cover ring gauge servicing unit has alleviated the labour intensity that a dead lift ring gauge detects greatly.But in use also run into new problem, be mainly reflected in: 1) weight of ring gauge weight+servicing unit surpasses 100 kilograms, and the simplicity of operation is relatively poor.2) because the adjusting of position height relies on the Current Collector Sleave adjusting, be not easy to fine setting, thereby because ring gauge and steel pipe center coaxiality deviation cause screw thread to pull.3) because centre-height is not easy to regulate, more dependence Current Collector Sleave, centre deviation cause " askew skewing hung " phenomenon to a certain degree easily, thereby the measuring accuracy of tight distance is exerted an influence.4) this servicing unit has requirement to matching used ring gauge structure: screw is measured face but not circumferencial direction is not suitable for the ring gauge of screw in ring gauge circumferencial direction structure at ring gauge.
Summary of the invention
The purpose of this utility model is to design a kind of self-balance type servicing unit that is applicable to screw at the ring gauge circumferencial direction, be mainly used in by alleviating the ring gauge deadweight, self-equilibrating weight reduces the labour intensity of check, improve the convenience of check, and the damage that alleviates the ring gauge double thread to a certain extent.
For achieving the above object, the technical solution of the utility model is:
A kind of self-balance type servicing unit that is applicable to screw at the ring gauge circumferencial direction matches with ring gauge; It comprises, the skeleton body comprises forward and backward plate and at least three axis of rolling between forward and backward plate; Forward and backward plate is connected to form a framed structure by the axis of rolling; Offer annular guide channel on the header board; The described axis of rolling evenly distributes and is positioned at the annular guide channel outside, and axis of rolling two ends are sheathed rolling bearing respectively; The ring gauge collar, the circular arc supporting construction that is arranged between the forward and backward plate of skeleton body, forms by described rolling bearing; Described ring gauge and this ring gauge collar are fixed; Adjusting handle stretches into the ring gauge collar from described skeleton body header board annular guide channel and to be connected; Suspension hook is arranged at described skeleton bodies top.
Further, also establish a Spring balancer, be connected with described suspension hook.
Again, the described ring gauge collar links to each other with described ring gauge by bolt.
The utility model is put by a ring gauge collar and is carried out the transition connection, promptly this ring gauge collar and ring gauge are fixed, link to each other with skeleton structure by three rolling bearings simultaneously, the arc diameter of three rolling bearing formation is more bigger than the ring gauge collar of corresponding size, wherein two belows is driving wheel, and the top is an auxiliary wheel.
Roller has the circular baffle plate of both direction in the side, prevent to rock, and avoids ring gauge axially coming off in use.Simultaneously the position of circular baffle plate can't be interfered with the ring gauge handle, reliable and stable when guaranteeing rotation.
The beneficial effects of the utility model
After adopting the utility model, each only the need lies in whole device on the ground, and ring gauge is placed on collar inside, twists the steady job that good bolt made in Great Britain can be finished ring gauge.Then whole device is hung in below cantilever hangs by Spring balancer, when operating, the checked operation personnel can easily whole device be drawn to the measuring position up and down, and unmanaged flexibility within a certain height, when using ring gauge, firmly better concentrate on the measuring process that circumferencial direction rotates, well alleviated labour intensity, improve measurement accuracy, reduced the damage of ring gauge double thread.

Embodiment
Referring to Fig. 1～Fig. 3, a kind of self-balance type servicing unit that is applicable to screw at the ring gauge circumferencial direction of the present utility model matches with ring gauge; It comprises,
Skeleton body 1 comprises header board 11, back plate 12 and three axis of rolling 13,14,15 between forward and backward plate; Forward and backward plate 11,12 is connected to form a framed structure by the axis of rolling 13,14,15; Offer annular guide channel 111 on the header board 11; The described axis of rolling 13,14,15 evenly distributes and is positioned at annular guide channel 111 outsides, and the axis of rolling 13,14,15 two ends are sheathed rolling bearing 16 respectively;
The ring gauge collar 2, the circular arc supporting construction that is arranged between the forward and backward plate 11,12 of skeleton 1 body, forms by described rolling bearing 13,14,15; Described ring gauge 6 is fixing with this ring gauge collar 2;
Adjusting handle 3 stretches into the ring gauge collar 2 from described skeleton body 1 header board 11 annular guide channels 111 and to be connected; Suspension hook 4 is arranged at described skeleton body 1 top.
Further, also establish a Spring balancer 5, be connected with described suspension hook 4.
Again, the described ring gauge collar 2 links to each other with described ring gauge 6 by bolt 7.
Spring balancer has guaranteed that ring gauge contacts evenly with the steel pipe screw thread of measuring in a circumferential direction in the measuring process.Suspension hook 4 links to each other with skeleton body 1 with hanger 7.Actions such as body skeleton 1 does not rotate in measuring process play the support ring gauge collar 2 grades.The ring gauge collar 2 is fixing by bolt and ring gauge 6, by adjusting handle 3 the ring gauge circumferencial direction is rotated and measures action.The ring gauge collar 2 is fixed in the body skeleton by rolling bearing, and relative motion can take place.
The utility model makes the ring gauge set bolt on circumferencial direction rather than the face of measurement structure, simultaneously because of its self-equilibrating effect, has effectively reduced the damage of ring gauge double thread.
