Description

The useful model "Panoramic Bore Gauge" belongs to the control and measuring instruments for measuring the internal diameters of pipes, it can be used to control elongated pipe surfaces in mechanical engineering and the oil and gas industry.

In the manufacture and repair of oil and gas pumps, extrusion and casting machines, barrels and machine tools, it is necessary to control the diameters and condition of internal elongated pipe surfaces in conditions of limited access.

Usually, when checking the internal cylindrical surface, especially with wear (mechanical, abrasive, corrosion-erosion), a large number of measurements are performed along the length of the pipe and (with a 120-degree turn in each section) to determine wear zones and deviations from the nominal diameter of the pipe.

The problem of a large number of measurements and limited vision increases rapidly in the case of monitoring the internal diameters of elongated pipes.

The task of the proposed useful model "Nutromir panoramic" was to reduce by 40-90

Costs for measuring the internal diameters of elongated pipes.

To measure the internal diameters of pipes, indicator (two-point) gauges (1) and micrometric three-point gauges (21) are used.

Both types of internal gauges (1, 2| have certain differences, while both types of internal gauges are identical in terms of functional purpose and node structure (rods, rods, centering-measuring nodes, measuring devices).

Rods of both types of internal gauges hold centering-measuring nodes and counting devices, which are placed on different sides of the rods. With the help of rods, centering-measuring nodes are deepened inside the measured pipes;

The rods of both types of feeler gauges (1, 2| are placed inside the rods and provide a mechanical connection between the centering-measuring nodes and the reference devices: - For all two-point indicator feeler gauges (1| the movement is initiated by one movable reference tip of the centering-measuring node, from which the prismatic or lever systems are transformed into longitudinal movements of the rod, through which the protocol movements are transmitted to the measuring device; - For three-point micrometric calipers (2| movements are always initiated from

From the micrometric head of the measuring unit, they are then transmitted through the rod to the centering and measuring unit, in which, with the help of a longitudinal cone system or a rotary cardan system, they are further transformed into gradual movements of the three measuring tips.

Centering and measuring units of both types of feeler gauges (1, 2| ensure centering in the pipe and movement of the measuring tips: - three movable measuring tips for micrometric three-point feeler gauges (21; - two measuring tips for two-point indicator feeler gauges (one fixed tip and one movable tip inside centering bridge) (11;

Both types of feeler gauges (1, 2) have corresponding movements of the rods: - circular movement of the rods for micrometric three-point feeler gauges (2| in the case of using the cardan system of the centering and counting unit; - gradual movement of the rods for micrometric three-point feeler gauges (2| in the case of using the conical system - gradual movement of rods for two-point indicator gauges (|1| with lever or prismatic systems in the centering and measuring unit.

The measuring devices of both internal gauges (micrometric or indicator) (1, 2| determine and display the movement of the corresponding rods in analog or digital measurements of both types of internal gauges (1, 2| using the appropriate micrometric heads or the appropriate indicator heads.

As a prototype of a useful model, the "Indicator Extended Gutometer" according to the Ukrainian Patent No. 103980 |ЗЙ was chosen, in which the measuring depth up to 5000 mm is provided with an elongated rod, composed of several pipes with centering tubes, rigidly connected by threaded connectors, and an elongated rod, consisting of several tubes, at the ends of which are installed, in pairs, external and internal conical centers, standard centering and measuring nodes and counting devices are also used. "Nutrometer indicator elongated" IZ| is mass-produced in Ukraine and is, today, the longest internal measuring device in the world.

The disadvantage of the patent-prototype (|IZ|) is the need to perform an excessive number of measurements when monitoring worn pipes, since it is impossible to determine and limit the necessary measurements 60 exclusively in problem areas of the pipe.

The essence of the proposed useful model "Panoramic Nutrometer" consists in reducing the volume of contact measurements by means of preliminary visual selection of the necessary measurement zones.

The panoramic borehole gauge consists of a rod 1, at the ends of which a centering-measuring unit 2 and a counting device З are installed, between which, inside the rod 1, a rod 4 moves, according to a useful model, the rod 1 has a circular scale 5 and a depth scale 6, also on rod 1 has rotating brackets 7 with one or more panoramic cameras 8, which, together with the counting device 3, are connected to the counting-computer unit 9.

The rod 1 can be either single-tube or folded and extended according to the known prototype patent |1). On one side, a centering-counting unit 2 and rotating brackets 7 with panoramic cameras 8 are installed on the rod 1. On the other side, a circular scale 5 and a counting device З are installed on the rod 1, next to which it is possible to install a counting-computer unit 9.

A depth scale 6 is placed along the length of rod 1.

Inside the rod 1 is a movable rod 4, integral or composed of several parts according to known designs (1, 2, Z.

The centering-measuring unit 2 is made traditionally for all types of internal gauges (1, 21.

Counter device C should be digital wireless, preferably according to known modern solutions |41.

A circular scale 5 is installed on the rod 1, which can be adjusted along the rod 1 when the rod 1 is deepened into the pipe to be measured: - in the form of an analog scale-ring, divided into 360 angular degrees (in the plane next to the end of the pipe or along the outer plane above the surface of the pipe ), which turns together with rod 1 relative to the line on the outer surface of the pipe being measured (which is a structural element, applied with paint, chalk, a sketch, on a clamp, on a magnet or another means); - in the form of an analog protractor 0-360 degrees pendulum type; - in the form of a digital protractor 0-360 degrees (pendulum, incremental, optical-mechanical or other type); - in the form of a digital wireless protractor 0...360 degrees (pendulum, incremental, optical-mechanical or other type), connected to the counter-computer unit 9 by wired or wireless means.

The circular scale 5 controls the angular coordinates of the placement of the centering-measuring unit 2 and the panoramic cameras 8 (in the indicated section of the pipe measured at a given depth) in the pipe when they are rotated together with the rod 1.

Connecting the digital circular scale 5 by wire or wireless to the counter-computer unit 9 provides logging, mathematical processing and archiving of the angular coordinate (in a specific section at the depth of the pipe) of the specified places in the pipe for further contact measurement of the internal diameter of the pipe.

The depth scale 6 is placed along the rod 1, starting from the centering-measuring unit 2 and ending with the measuring device 3: - in the form of an analog scale (marked on the body of the rod 1 or the measuring tape on the rod 1) with a length equal to the measurement depth of the utility model "Panoramic Gut Gauge "; - in the form of a scale with a digital reading (incremental, optical or other) with a length equal to the depth of measurements; - in the form of a scale with a digital reading, connected to the counting computer unit 9 by wire or wireless.

Depth scale 6 determines the linear coordinates of the immersion of the centering-measuring node in the depth of the measured pipe. The combination of linear coordinates from the depth scale 6 with angular coordinates from the circular scale 5 completely identify the position of the measuring tips in the pipe. Connecting the depth scale 6 by wire or wireless to the counter-computer unit 9 provides logging, mathematical processing and archiving of indicators of penetration into the pipe.

Panoramic cameras 8 are installed in rotating brackets 7, which are placed on the rod 1 near the centering-measuring unit 2. Panoramic cameras 8 (one or more) are aimed at the areas where the measuring tips of the centering-measuring unit 2 are placed or at other places of the pipe.

Panoramic cameras 8 are connected to the counter-computer unit 9 by wire or wireless for visual control and image archiving.

The following options for installing panoramic cameras 8 are possible:

- alone on rod 1 with a limited field of view (60-120 angular degrees or other), while the camera must be turned 3-6 times (60-20 angular degrees) using rod 1 around its own axis of rod 1 to obtain a full panoramic image in 360 degrees; - group placement around the rod 1 of several panoramic cameras 8 (2, 3, 4,6 pieces) provides a complete 360-degree panoramic image of the inner surface of the measured pipe around the centering-measuring node 2 or in another section of the measured pipe; - group placement along the rod 1 of several (2-9 pieces or more, at the request of the manufacturer and with the possibility of display on the counter-computer unit 9) provides a panoramic image along the inner surface of the pipe being measured; - mixed group placement in several sections around and along the rod 1 of a large number (8-24 pieces or more, at the manufacturer's request and according to the capabilities of the counter-computer unit 9) of panoramic cameras 8 provides the most complete visual picture for each recess of the rod 1 in the pipe

The rotating clips 7 hold one or more panoramic cameras 8 and are made in the form of adjustable rings installed along the rod 1. The rotating clips provide optimal angles of inclination of the panoramic cameras 8 (20-160 degrees relative to the creating rod 1) and optimal distance (10-100 mm) approach of panoramic cameras 8 to the inner surface of the measured pipe.

The counter-computer unit 9 receives, processes and displays on its own display information from the panoramic cameras 8, the circular scale 5, the depth scale b and the diameter indicators in the determined radial coordinates of the selected sections in the measured pipe.

Thus, after the stage of visual control of images of panoramic cameras 8, selection and logging of radial coordinates (angular coordinates in the section and depths of sections in selected places of the measured pipe), the necessary contact measurements of pipe diameters, logging, mathematical processing and archiving of all results in a counting computer are performed computer block 9.

The useful model "Panoramic Endometer" does not require any personal skills from the user, except for the ability to use endometers and endoscopes, and is used as follows:

From 1) Assemble the "Panoramic Gut Gauge" by installing panoramic cameras 8 on rotating brackets 7 in accordance with the nominal diameter of the measured pipe. 2) Deepen and turn (if necessary) the "Panoramic Gut Gauge" in the measured pipe and, with the help of images from the panoramic cameras 8 on the display of the counter-computer unit 9, inspect the inner surface of the pipe and determine the places where there are surface defects. 3) At the first ("visual") stage, with the help of panoramic cameras 8, places with pipe defects are selected and the radial coordinates of these places are determined using a circular scale 5 and a depth scale 6. 4) The determined radial coordinates of the selected defective places are recorded in the countdown computer unit 9 manually (when using analog scales 5 and 6 as well as digital scales 5 and 6 without external communication) or using wired and wireless communication (when using digital scales 5 and 6 with external communication). 5) At the second ("contact") stage, rod 1 of the "Nutromir panoramic" is inserted into the measured pipe in accordance with the previously determined radial coordinates of the problem areas of the pipe and, with the help of the measuring tips of the centering and measuring unit 2, the diameters of the selected areas are determined. b) Indicators of determined pipe diameters are displayed by measuring device 3, from which they are recorded manually (when using analog measuring devices C as well as digital measuring devices C without external communication) or by means of wired and wireless communication (when using digital measuring devices C with external communication). 7) The counter-computer unit 9 records the indicators of the measured diameters in the selected places of the pipe, providing the radial coordinates of these places and visual images of the inner surface of the pipes. 8) The user has the opportunity to calculate the necessary indicators of deviations of the diameters of the inner surface of the measured pipe (cylindricity, conicity, depth of local defects, average and out-of-roundness for each section). 9) If necessary, an additional visual examination of problematic areas of the inner surface of the pipe and repeated "contact" measurements of selected areas of the pipe are possible. 10) Availability of preliminary visual control and selection of measurement sites are especially important for elongated pipes and for responsible measurements, when it is necessary to carry out a large number of measurements, which can be reduced by 2-20 times due to visual selection.
