Embodiment Construction

[0017] The present invention will be described in further detail below with reference to the drawings.

[0018] Such as figure 1 , figure 2 As shown, in the present invention, the front and rear beam assemblies 1, 2 and the hydraulic cylinder 4 of the hydraulic mechanism are connected to form a rectangular structure. The front and rear beam assemblies 1 and 2 are connected by a single beam. One end of the front beam assembly 1 is detachably connected to the U-shaped connecting plate 14 on the rear beam assembly 2 through bolts 9 through the U-shaped connecting plate 14 and the backing plate 15 The other end is detachably connected with the flange of the hydraulic cylinder 4 by bolts. Slide rails 16 are provided on both sides of the front beam assembly 1, and a slide seat assembly 7 that can reciprocate up and down is arranged in the content. The sliding seat assembly 7 has an annular sleeve extending from the main body of the front beam assembly, and the connecting nipple 12 i...

Abstract

The invention comprises a front beam assembly, a rear beam assembly, a control console and a hydraulic mechanism. The front and rear beam assemblies use single beam connection; the one end of front beam assembly is connected to the rear beam assembly in dismountable way; the other end of it is connected to the hydraulic cylinder in dismountable way; the hydraulic cylinder in the hydraulic mechanism is connected to the hydraulic fluid connection of the control console via pipeline; the tested component is mounted in the front beam assembly and rear beam assembly; the one end of the tested component connected to the front beam assembly can be stretched by hydraulic fluid cylinder. Said front beam assembly and rear beam assembly is a combined type mono-spar structure and can be dismounted according to the requirement.

Description

Technical field [0001] The invention relates to a machine for performing temporary tests on the oil field, in particular to a tensile delay test machine for downhole tools in the oil field. Background technique [0002] At present, many oilfields often need to perform tensile delay tests on downhole tools on site to test the performance of the tools, such as testers, packers, jars and safety seals. It is often necessary to perform tensile extension tests on site. Time and shear pin shear test. Existing tensile time-delay testing machines mostly use two beams as a whole, the test piece is placed between the two beams, and the test piece is subjected to tensile testing through the control of the hydraulic mechanism of the console. The testing machine for integral beams is bulky, has enough space for placement, is heavy, and is not easy to carry as a whole, and it is not conducive to transportation to the oil well site for operation. Summary of the invention [0003] In order to so...
