Description

Technical Field

[0001] This utility model relates to the field of water-cooled wall pipe testing technology, specifically a tool for ball-passing tests on water-cooled wall pipes. Background Technology

[0002] Water-cooled walls, superheaters, and reheaters in thermal power plants can reach heights of 60-70 meters. During manufacturing, they are typically produced in panels, each panel consisting of multiple parallel pipes. These pipes can be bent, straight, or a combination thereof, and may or may not contain fins. Each panel is manufactured individually, transported to the site for a ball-passing test, and then assembled into a complete unit, ultimately forming the integrated water-cooled wall, superheater, reheater, or economizer. The ball-passing test involves placing a small ball at one end of a pipe, blowing in compressed air, and simultaneously observing whether the ball can pass smoothly through the other end. If a pipe fails the ball-passing test, it indicates insufficient flow capacity, potentially leading to pipe bursting during operation.

[0003] The ball-passing test of water-cooled wall tubes requires a series of carefully designed tools and equipment to ensure the accuracy of the test results and the safety of boiler operation. Currently, the ball-passing test is conducted individually or in batches of the same size, which is inefficient, time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a tool for ball-passing tests on water-cooled wall tubes, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tool for a ball-passing test of water-cooled wall tubes includes a device body and further includes:

[0007] The base consists of several bases, each with its upper end fixedly connected to the lower surface of the device body around the perimeter.

[0008] A limiting mechanism, wherein a plurality of limiting mechanisms are provided and arranged in an array on the upper surface of the device body;

[0009] Two clamping mechanisms are provided and are respectively fixedly connected to both ends of the device body;

[0010] The upper cover plate, the lower end of which is hinged to one side of the upper surface of the device body;

[0011] The rubber pad is fixedly connected to the middle of one side of the upper cover plate;

[0012] The controller is fixedly connected to one side of the device body;

[0013] With the clamping mechanism and other features, multiple water-cooled wall tubes that need to be tested can be placed into it for testing at the same time. It can also test water-cooled wall tubes of different sizes, thereby effectively improving the efficiency of the test and saving time and effort.

[0014] As a preferred embodiment of this utility model

[0015] The limiting mechanism includes:

[0016] A limiting groove is formed on the upper surface of the device body;

[0017] A bottom circular groove is formed at the lower end of the limiting groove;

[0018] Two limiting plates are provided and are slidably disposed on both sides of the limiting groove;

[0020] Two inclined ends of the limiting plate are provided and are respectively opened on the upper end of adjacent limiting plates;

[0021] Before the test, the water-cooled wall tube to be tested is placed into the limiting groove. Through the limiting plate, the water-cooled wall tube can quickly slide into the limiting groove on the inclined side of the limiting plate. At this time, the limiting pressure column squeezes the limiting plate through the set spring to clamp the water-cooled wall tube and fix it. At the same time, the limiting plate can clamp water-cooled wall tubes of different sizes, thereby improving the applicability and test range of this device.

[0022] As a preferred embodiment of this utility model

[0025] A clamping ring, wherein a plurality of clamping rings are provided and the array is fixedly connected to the upper surface of the clamping base;

[0026] The sliding board is provided in a plurality of units and is slidably disposed on the upper and lower sides inside each clamping ring;

[0027] Clamping posts are provided in a plurality of them and arranged in an array on the upper and lower sides of each clamping ring. The two ends of each clamping post are fixedly connected to the adjacent sliding plate and one side of the clamping ring, respectively.

[0028] A plurality of inclined fixing plates are provided and are respectively fixedly connected to both ends of each sliding plate;

[0029] After the water-cooled wall tube is clamped inside the limiting mechanism, one end of the water-cooled wall tube is slid into the clamping ring. The other end of the water-cooled wall tube can be quickly slid into the slide plate through the inclined fixing plate and then fixed by the clamping column to complete the fixation of one end of the water-cooled wall tube. At this time, the test tool can be quickly inserted from the other end of the slide plate to complete the docking and fixation of the water-cooled wall tube test.

[0032] 2. In this utility model, before the test, the water-cooled wall tube to be tested is placed into the limiting groove. By limiting the limiting plate, the water-cooled wall tube can quickly slide into the limiting groove on the inclined side of the limiting plate. At this time, the limiting pressure column squeezes the limiting plate through the set spring to clamp the water-cooled wall tube and complete the fixation of the water-cooled wall tube. At the same time, the limiting plate can clamp water-cooled wall tubes of different sizes, thereby improving the applicability and test range of this device.

[0033] 3. In this utility model, after the water-cooled wall tube is clamped inside the limiting mechanism, one end of the water-cooled wall tube is slid into the clamping ring. One end of the water-cooled wall tube can be quickly slid into the slide plate through the inclined fixing plate and then fixed by the clamping column to complete the fixing of one end of the water-cooled wall tube. At this time, the test tool can be quickly inserted from the other end of the slide plate to complete the docking and fixing of the water-cooled wall tube test. Attached Figure Description
