Abstract

The invention discloses an elevator tension (pressure) testing device and a using method thereof and overcomes the shortcoming that the conventional specification tension (pressure) test device can only test tensions (pressures) on elevators of the same specifications. The device is formed by connecting a cap, a cylinder, a V-shaped support block, a cylindrical head screw, a gasket, a T-shaped nut, a base plate and a base, wherein the cap is contacted with a stressed hole on the top of the elevator; the cylinder and the V-shaped support block are mounted together; the V-shaped support block and the base plate are arranged together and fixed by the cylindrical head screw, the gasket and the T-shaped nut; the inward and outward movement distance of the V-shaped support block can be adjusted by unfastening and fastening the cylindrical head screw and the T-shaped nut; the base plate is fixed on the base plate through the cylindrical head screw, the gasket and the T-shaped nut, and the movement distances of the base plate toward the middle and outside can be adjusted by unfastening and fastening the cylindrical head screw and the T-shaped nut.

Description

Elevator pulling force/pressure experimental device and method of application

One, the present invention relates to petroleum gas and geological drilling industry and in Drilling oil, gas well or geologic prospecting operation, be used for outstanding experimental technique, especially elevator pulling force (pressure) test unit and method of application of holding the tubing string elevator.

Two, background technology: at present; Elevator has 15 kinds of specifications from 25USton to 750USton; Before product export, to carry out pulling force (pressure) test to elevator; Pulling force (pressure) test unit that like this will 15 kinds of specifications of processing and manufacturing judges with this whether elevator meets the standard code of SY/T5035-2004.

Three, the purpose of this invention is to provide a kind of general elevator pulling force (pressure) test unit and method of application; It has overcome the defective that existing a kind of specification pulling force (pressure) test unit can only carry out pulling force (pressure) test corresponding to the elevator of same size; The technical solution adopted for the present invention to solve the technical problems is: only design a kind of pulling force (pressure) test unit, just can carry out pulling force (pressure) test to the elevator of all specifications through four V-type back-up blocks of two backing plates of horizontal adjustment and vertical adjustment.The elevator of different size; Its modal length L is different with the size of two ends hanger thickness B, and the distance of two backing plates of lateral adjustments (to middle or outside) makes two distance and distances between the hanger of elevator two ends between the support cylinder body consistent; And then the distance between adjustment (forward, backward) four V-type back-up blocks; The two sides distance that makes four V-type back-up blocks and two ends hanger thickness B is rationally regulated the distance between each supporter for minimum, pulling force (pressure) minimum that when doing pulling force (pressure) test pulling force (pressure) test unit is received; Promptly reasonably protected experimental provision, simultaneously again can safe completion pulling force (pressure) pilot project.At this moment, be put into test unit on the testing machine worktable, the pressure head of testing machine touches pressure cap, is pressurized to the test pressure value on request gradually, thereby can accomplish pulling force (pressure) test mission to all specification elevators.

The present invention is formed by connecting pressure cap, right cylinder, V-type back-up block, fillister head screw, packing ring, T type nut, backing plate and base; Pressure cap contacts with the stress hole position at elevator top; Right cylinder and V-type back-up block are installed together; V-type back-up block and backing plate are installed together, and are fixed by fillister head screw, packing ring and T type nut; Unclamp, tighten fillister head screw and T type nut, can adjust the V-type back-up block inwards, outside distance; Backing plate is fixed on the base through fillister head screw, packing ring and T type nut, unclamps, tightens fillister head screw and T type nut, can adjust backing plate to middle and outside distance.

Method of application: the action 1, put into elevator top tapered hole to pressure cap; Penetrate two right cylinders to the elevator two ends of slinging; Unclamp fillister head screw and T type nut, the distance of adjustment backing plate makes V-type back-up block and two cylindrical positions consistent; Tighten fillister head screw by the location of the T type nut in the T type groove then, thereby accomplished horizontal displacement.

Action 2, unclamp fillister head screw and T type nut; The two sides distance of adjusting four V-type back-up blocks and two ends hanger thickness is minimum, tightens fillister head screw by the location of the T type nut in the T type groove then, thereby has accomplished displacement longitudinally; So far, the debugging of pulling force (pressure) test unit is accomplished.

The invention has the beneficial effects as follows that appearance just can carry out pulling force (pressure) test with a kind of pulling force (pressure) test unit to the elevator of all specifications through four V-type back-up blocks of two backing plates of horizontal adjustment and vertical adjustment.

Four, description of drawings: Fig. 1 is the structural representation of pulling force (pressure) test unit, among the figure, and 1, pressure cap 2, right cylinder 3, V-type back-up block 4, fillister head screw 5, packing ring 6, T type nut 7, backing plate 8, base

Fig. 2 is the side view of pulling force (pressure) test unit

Five, embodiment: in Fig. 1 and Fig. 2, pressure cap 1 contacts with the stress hole at elevator top, and right cylinder 2 is installed together with V-type back-up block 3, and V-type back-up block 3 is installed together with backing plate 7, and fixing by fillister head screw 4, packing ring 5 and T type nut 6; Unclamp, tighten fillister head screw 4 and T type nut 6, can adjust the V-type back-up block inwards, outside distance; Backing plate 7 is fixed on the base 8 through fillister head screw 4, packing ring 5 and T type nut 6, unclamps, tightens fillister head screw 4 and T type nut 6, can adjust backing plate to middle and outside distance.

Method of application: the action 1, put into elevator top tapered hole to pressure cap 1; Penetrate two right cylinders 2 to the elevator two ends of slinging; Unclamp fillister head screw 4 and T type nut 6, the distance of adjustment backing plate 7 makes the position of V-type back-up block 3 and two right cylinders 2 consistent; Tighten fillister head screw 4 by 6 location of the T type nut in the T type groove then, thereby accomplished horizontal displacement.

Action 2, unclamp fillister head screw 4 and T type nut 6; The two sides distance of adjusting four V-type back-up blocks 3 and two ends hanger thickness is minimum; Tighten fillister head screw 4 by 6 location of the T type nut in the T type groove then; Thereby accomplished displacement longitudinally, so far, the debugging of pulling force (pressure) test unit is accomplished.
