Description

Technical Field

[0001] The present application relates to the field of non-destructive testing technology, and in particular to an adjustable tube screen scanner. Background Art

[0002] The tube panel scanning device is specifically designed for inspecting the tube panels of key components such as water walls, low-temperature reheaters, and economizers in thermal power boilers. Using this device for wear and explosion prevention inspections overcomes the limitations of conventional measuring tools, significantly improving inspection speed and reducing the number of inspectors required while maintaining high accuracy. It can rapidly perform ultrasonic thickness measurement, visual video inspection, and pipe creep inspections on large-scale tube panels without requiring polishing. The device also simultaneously saves visual video and thickness data for easy verification later. This represents a significant advancement in wear and explosion prevention inspection technology, significantly ensuring safe boiler operation.

[0003] When using the tube screen scanning device in the related art, the inventor found that the space in some measurement environments is relatively narrow. Due to the connection structure between the handle of the scanning device and the main body, the range of movement of the handle is limited. When measuring the mobile scanning device, the handle is easily blocked by obstacles in front and cannot continue to move, resulting in an incomplete scanning range or inaccurate scanning results. Utility Model Content

[0021] The following is combined with Figure 1 -Attached Figure 2 , further details of this application are given.

[0022] Example: This application proposes an adjustable tube screen scanner, referring to Figure 1-2 The device includes a measuring body, a device host 1 and an adjustment control rod 2 arranged in sequence, and the measuring body includes a probe device 3 and a camera device 4.

[0023] The device host 1 includes an external shell, an internal control circuit board, a display screen and control buttons on the shell, and a battery module inside the shell. The shell is a flat rectangular parallelepiped with a thickness of less than 30mm. The shell is also provided with a circuit structure connected to an external tablet computer and a charging interface.

[0024] The adjustment control rod 2 is connected to one end of the measuring body 1 and comprises a core rod 21, a sliding adjustment sleeve 22, and a telescopic handle 23. The core rod 21 is a straight round rod with a threaded section at one end. The threaded section connects the core rod 21 to the housing of the device main body 1, allowing for adjustment of the threading depth and the exposed length of the core rod 21. The outer surface of the core rod 21 is axially provided with at least one row of positioning grooves 25. In this embodiment, the positioning grooves 25 are configured as round blind holes. A ball bearing is provided on the end of the core rod 21 away from the device main body 1 to reduce frictional resistance when the core rod 21 contacts an object and moves.

[0025] The sliding adjustment sleeve 22 is slidingly sleeved on the core rod 21 and can be fixed in position on the core rod 21. The sliding adjustment sleeve 22 is set as a circular sleeve with an inner hole shape the same as the cross-sectional shape of the core rod 2, and a locking bolt 26 is radially threaded on the side wall of the sliding adjustment sleeve 22. The end of the locking bolt 26 can pass through the side wall of the sliding adjustment sleeve 22 and be inserted and tightened into the positioning groove 25 to achieve the position fixation of the sliding adjustment sleeve 22 after sliding on the core rod 21.

[0026] The telescopic handle 23 is connected to the sliding adjustment sleeve 22 by rotating at its front end. Two connecting lugs 27 are disposed at the front end of the telescopic handle 23. The two connecting lugs 27 are connected to the side walls of the sliding adjustment sleeve 22 via a rotating shaft. The axis of the rotating shaft of the connecting lugs 27 passes through the central axis of the core rod 21, allowing the telescopic handle 23 to rotate coaxially with the core rod 21. In this embodiment, the telescopic handle 23 is configured as a multi-section telescopic square tube. One side of the tube is provided with a locking groove 24 that extends through the end surface of the telescopic handle 23 where the connecting lugs 27 are disposed. As the telescopic handle 23 rotates about its axis, the core rod 21 can rotate until it is fully embedded in the locking groove 24. At this point, the telescopic handle 23 is parallel to or coaxial with the device body 1. The side walls of the locking groove 24 are provided with a locking block that can retain the core rod 21.

[0027] The probe assembly 3 is rotatably connected to the end of the device main unit 1 away from the adjustment control rod 2. The probe assembly 3 is used to contact the tube panel to perform ultrasonic thickness measurement and pipeline creep inspection. The probe assembly 3 comprises a probe mounting frame 31, a probe 32, a reset spring 33, and a permanent magnet 34. In this embodiment, the probe mounting frame 31 is a rectangular ring structure with rounded corners. The probe mounting frame 31 is rotatably connected to the end of the device main unit 1 via a short side plate on one side. The probe 32 is rotatably connected between the two long side plates of the probe mounting frame 31 via a rotation axis. The rotation axis of the probe 32 is parallel to the rotation axis of the probe mounting frame 31 on the device main unit 1. The side of the probe 32 facing the tube panel inspection surface is provided with a wear-resistant protective plate to protect the lens of the probe 32. The side of the probe 32 facing the tube panel inspection surface is embedded with a permanent magnet 34. The permanent magnet 34 does not protrude from the measuring surface of the probe 32, allowing the probe 32 to effectively adhere to the inspection surface. The entire device can be easily moved and is not prone to slipping.

[0028] The two short side plates of the probe mounting frame 31 are connected to the probe 32 via a reset spring 33. The reset springs 33 are relatively arranged on both sides of the rotating shaft of the probe 32. In this embodiment, two reset springs 33 are arranged on the left and right sides of the probe 32. The axis of the reset spring 33 is perpendicular to the axis of the rotating shaft of the probe 32. The double row of reset springs 33 can allow the probe 32 to move smoothly laterally and can reset the probe 33 in time.

[0029] The camera device 4 is fixedly connected to the outside of the short side plate of the probe mounting frame 31 away from the device host 1, and includes a camera and a lighting lamp. The video head is connected to an external tablet computer through a data transmission line, and the lighting lamp is connected to the power module inside the device host 1.
