Abstract

The utility model relates to the technical field of test devices for engineering tubes and the matched members thereof, and particularly relates to a full-scale bending test device for a petroleum tube. The detects of inconvenience in use and incapacity of meeting a part of test requirements exist in the prior art. In order to overcome the shortages in the prior art, the technical scheme provided by the utility model is as follows: the full-scale bending test device for a petroleum tube comprises end part fixing devices and bending load devices, wherein two groups of the end part fixing devices are arranged oppositely; each end part fixing device comprises an end part fixed seat and a connecting end head; the connecting end head has a block-shaped structure with two equally-long connecting arms on the upper surface and the lower surface; the connecting end head is hinged with the end fixed seat; a pair of the bending load devices which are arranged in parallel are arranged between the two groups of the end part fixing devices; and the two ends of each bending load device are hinged with the connecting arms of the connecting end head respectively. The full-scale bending test device for a petroleum tube disclosed by the utility model is convenient to operate, and expanded in test range.

Description

A kind of petroleum pipeline Full-size bending test device
Technical field
The utility model relates to the proving installation technical field of engineering tubing and supporting member thereof, is specifically related to a kind of petroleum pipeline Full-size bending test device.
Background technology
Development along with oil and gas industry, the nonpetroleum tubing that needs exploitation, and the anti-bending strength of novel tube had relatively high expectations, therefore need to test and estimate structural intergrity and the sealing integrity of tubing under bending stress, design a kind of bending load mechanical test machine, be used for the full-scale bending property test of tubing and estimate especially seeming urgent.
The petroleum pipeline Full-size bending test device of prior art comprises crossbeam, bending hydraulic cylinder and crooked restraint device at present, can apply or four-point bending at 3 to sample as required.Its major defect is that bending hydraulic cylinder and crooked restraint device need to be applied in the sample effective range, owing in the sample effective range heating, outer pressure cylinder, strainometer, sensor device being installed usually, very inconvenient so operate, some test even can't realize.
The utility model content
The utility model relates to a kind of petroleum pipeline Full-size bending test device, the shortcoming of using inconvenience and can't satisfying the part test requirement to overcome prior art.
The deficiency that exists for overcoming prior art, the technical scheme that the utility model provides is: a kind of petroleum pipeline Full-size bending test device, its special character is: comprise device for fixing end part and bending load device, described device for fixing end part is two groups and is oppositely arranged, device for fixing end part comprises end anchorage and connection end, described end anchorage is the block structure that offers U-shaped groove, the sidewall of end anchorage is provided with the pin shaft hole that runs through two sidewalls of U-shaped groove, described connection end is that upper and lower surface is with the block structure of two isometric linking arms, the middle part, side of described connection end offers pin shaft hole, the front end face middle part offers the sample fixed orifice, described connection end be arranged in the U-shaped groove of end anchorage and connection end and end anchorage hinged by the connecting pin that is arranged in the pin shaft hole, be provided with the bending load device that pair of parallel arranges between two groups of device for fixing end parts, the two ends of bending load device are hinged with the linking arm of connection end respectively, and described bending load device comprises interconnective telescopic connection rod and hydraulic cylinder on the same straight line.
Compared with prior art, the utility model has the advantages that:
1. the utility model adopts fixedly sample of hinged structure, so that sample produces Based on Pure Bending Moment, when having avoided 3 of present technology employings or four-point bending, near bending hydraulic cylinder and crooked restraint device sample is produced stress and concentrates.
2. the bending load device no longer acts in the sample effective length scope, can not affect sample other testing apparatuss are installed, and handled easily has enlarged trial stretch.
3. the employing telescopic connection rod can be regulated according to specimen length, makes things convenient for the control of moment of flexure size.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Wherein, 1-end anchorage, 2-connection end, 3-connecting pin, 4-telescopic connection rod, 5-hydraulic cylinder, 6-linking arm, 7-sample.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Referring to Fig. 1, a kind of petroleum pipeline Full-size bending test device, comprise device for fixing end part and bending load device, described device for fixing end part is two groups and is oppositely arranged, device for fixing end part comprises end anchorage 1 and connection end 2, described end anchorage 1 is for offering the block structure of U-shaped groove, the sidewall of end anchorage 1 is provided with the pin shaft hole that runs through two sidewalls of U-shaped groove, described connection end 2 is that upper and lower surface is with the block structure of two isometric linking arms 6, the middle part, side of described connection end 2 offers pin shaft hole, the front end face middle part offers the sample fixed orifice, described connection end 2 be arranged in the U-shaped groove of end anchorage 1 and and end anchorage hinged by the connecting pin 3 that is arranged in the pin shaft hole, be provided with the bending load device that pair of parallel arranges between two groups of device for fixing end parts, the two ends of bending load device are hinged with the linking arm 6 of connection end 2 respectively, and described bending load device comprises interconnective telescopic connection rod 4 and hydraulic cylinder 5 on the same straight line.
During use, end anchorage 1 is installed on the fixed frame, sample 7 two ends are installed in respectively in the sample fixed orifice of two connection ends 2, namely finish installation, wherein the hydraulic cylinder of one group of bending load device applies stretching (compression) load, the hydraulic cylinder of another group bending load device then applies compression (stretching) load, then sample 7 has been finished the bending load loading.During dismounting, sample 7 and connection end 2 dismantled get final product.
