Description

The utility model relates to the gas industry and is intended for use when carrying out diagnostic work on sections of the main gas pipeline.

In the existing method, an automated ultrasonic testing system (for example, “AVGUR-T”) is used to control tee connections with linings. This system requires periodic testing of its performance and configuration on a special setup sample of the enterprise, like any other diagnostic system. The sample is made from any unused tee, incl. defective, similar in basic parameters to the control object. To achieve the required stability of the sample, a temporary support (wooden structure) is made to provide the necessary free space and a stable position for installing the device on the tee outlet.

The disadvantage of the designs used is the difficulty of providing free space around the perimeter of the outlet, at the required distance from the edge of the main pipe for inspection. Besides:

under significant weight of the sample, the wooden structure is deformed, which can subsequently lead to its destruction. In this case, there are risks of its destruction and injury to specialists performing work on setting up (checking the functionality) of the AUGUR system;

For timely replacement of a deformed structure, in order to prevent its complete destruction, it is necessary to involve specialized lifting equipment.

The closest analogue to the claimed utility model is a processing table for holding workpieces (DE 20319159 U1, B23Q 1/03, 03/11/2004), selected as a prototype. Said processing table is designed to hold workpieces, in particular body parts for cars, trucks, ships, aircraft or spacecraft.

The disadvantages of the prototype are: lack of mobility and complexity of the design, which do not allow use in field conditions, insufficient strength to hold tees of various diameters.

The purpose of the utility model is to increase the safety of work on setting up (checking the operability) of the AVGUR system and to prevent the occurrence of additional financial costs that arise when replacing deformed elements of the supporting structure.

The technical result of the utility model is to increase safety and improve working conditions.

The task is solved, and the technical result is achieved by developing and using a universal metal structure for installing the enterprise sample (tees of various diameters 1420, 1220, 1020, etc. mm) with linings that ensure fixation of the sample to create the necessary conditions for work.

The claimed device is explained using:

fig. 1 - general view of the “tee” sample;

fig. 2 - general view of the proposed device.

The structure consists of rolled metal (iron sheets, profile and cylindrical pipes) using arc welding, hinged joints and clamps (Fig. 2). The structure is represented by a base, which is served by pipes 1, fixed to each other using profile pipes of rectangular cross-section 2. Using hinged joints 3 and clamps 4, the supporting dimensions of the structure are adjusted by increasing or decreasing the length of structural elements 2 according to the “pipe-in-pipe” type. fig. 2, according to the corresponding standard sample size. The design has three support posts 5, which ensure a stable position of the sample due to platforms 6, which are connected to the posts by welding with reinforcement due to triangular stiffeners 7. The design of the posts installed on a long section of pipe allows you to adjust the distance between the supports according to the same according to the “pipe-in-pipe” principle to the stops 8 and set the required position using the clamps 4. Damping pads 9 are installed on the support posts to ensure a stable position of the sample during operation.
