[0018] The boiler water wall pipe wall in the factory needs to be measured regularly to ensure the safe and stable operation of the pipe, and to avoid pipe burst and leakage accidents.

[0019] At present, when measuring the thickness of the boiler water wall pipe wall, the measuring personnel needs to operate the measuring equipment by erecting fixed supports or handheld, especially when measuring the pipe wall at a high place, an additional scaffold needs to be erected, which is time-consuming, laborious and labor-intensive, and the measuring efficiency is low.

[0020] Under this background technology, the present disclosure provides a boiler water wall pipe wall thickness measuring device, which can improve the measuring efficiency and reduce the labor cost.

[0021] The boiler water wall pipe wall thickness measuring device will be described below with reference to the drawings.

[0022] Figure 1 is the structural schematic diagram of the boiler water wall pipe wall thickness measuring device provided by the embodiment of the application. As Figure 1 shown, the device can include: a columnar body 110, four electromagnetic plates 120, three telescopic mechanisms 130.

[0023] The columnar body 110 is provided with a moving groove 111, the moving groove 111 is provided with a controllable moving block 112, the columnar body 110 is provided with a lifting assembly 170, and the output end of the lifting assembly 170 is fixedly connected with the controllable moving block 112.

[0024] Each electromagnetic plate 120 is provided with a controllable rotation shaft 121. The controllable rotation shaft 121 is connected to the columnar body 110 through a connecting arm 122. The end of the controllable rotation shaft 121 and the connecting arm 122 away from the columnar body 110 is fixedly connected.

[0025] Each telescopic mechanism 130 includes a support seat 131 and a telescopic rod 132. The support seat 131 is fixedly connected to the controllable movable block 112, and the telescopic rod 132 is disposed on the support seat 131.

[0026] One end of the telescopic rod 132 of the three telescopic mechanisms 130 is respectively provided with a thickness measuring mechanism 140, a coating mechanism 150 and a polishing mechanism 160.

[0027] For example, the presence or absence of magnetism of the electromagnetic plate 120 can be achieved by turning the power on and off.

[0028] For example, the lifting assembly 170 may include a hydraulic cylinder 171 and a hydraulic rod 172 (i.e., the output end of the lifting assembly 170). The hydraulic cylinder 171 is mounted on the columnar body 110, and the hydraulic rod 172 is fixedly connected to the controllable movable block 112 so that the controllable movable block 112 can move up and down.

[0029] For example, the controllable rotation shaft 121 can be the output shaft of the motor 1211 fixedly connected to the electromagnetic plate 120, and the controllable rotation shaft 121 is rotatably connected to the electromagnetic plate 120.

[0030] For example, a thickness measuring probe may be installed on the thickness measuring mechanism 140.

[0031] Specific usage instructions:

[0032] Taking the boiler water-cooled wall pipe on the left as an example, and using the thickness measuring device of this embodiment to measure vertically, firstly, the two electromagnetic plates 120 on the left are energized so that the thickness measuring device of this embodiment can be attached to the boiler water-cooled wall pipe for thickness measurement.

[0033] In the thickness measurement, first, the movement of the controllable moving block 112 is controlled by the lifting assembly 170 to make the polishing mechanism 160 at the expected polishing height, then the polishing mechanism 160 is moved left to close to the pipeline by adjusting the corresponding telescopic rod 132 of the polishing mechanism 160, and the polishing mechanism 160 starts polishing after reaching the expected position. After polishing, the polishing mechanism 160 is moved right to the initial position by adjusting the corresponding telescopic rod 132, the movement of the controllable moving block 112 is controlled by the lifting assembly 170 to make the coating mechanism 150 at the expected coating height (i.e. the expected polishing height), then the coating mechanism 150 is moved left to close to the pipeline by adjusting the corresponding telescopic rod 132 of the coating mechanism 150, and the coating mechanism 150 starts coating the thickness coupling agent after reaching the expected position. After coating, the coating mechanism 150 is moved right to the initial position by adjusting the corresponding telescopic rod 132, the movement of the controllable moving block 112 is controlled by the lifting assembly 170 to make the thickness measuring mechanism 140 at the expected thickness measuring height (i.e. the expected polishing height), then the thickness measuring mechanism 140 is moved left to close to the pipeline by adjusting the corresponding telescopic rod 132 of the thickness measuring mechanism 140, and the thickness measuring mechanism 140 starts measuring the thickness of the pipeline wall after reaching the expected position. After measuring, the thickness measuring mechanism 140 is moved right to the initial position by adjusting the corresponding telescopic rod 132.

[0034] After completing a thickness measurement, the controllable rotating shaft 121 on the upper right electromagnetic plate 120 can be controlled to rotate counterclockwise to make the upper right electromagnetic plate 120 rotate to the horizontal, the lower left electromagnetic plate 120 is then powered off, and the controllable rotating shaft 121 on the upper left electromagnetic plate 120 is controlled to rotate counterclockwise to make the whole thickness measuring device flip up until the upper right electromagnetic plate 120 contacts the boiler water wall pipeline and is powered on to be adsorbed on the boiler water wall pipeline, completing a flip.

[0035] Subsequently, the same principle can be followed to continue flipping to move the whole thickness measuring device upward to reach the next thickness measuring position for thickness measurement.

[0036] The four electromagnetic plates and the controllable rotating shafts can make the whole thickness measuring device flip around one controllable rotating shaft to reach the expected position, and the position of the thickness measuring mechanism, the coating mechanism and the polishing mechanism can be further adjusted by moving the controllable moving block in the moving slot, thereby realizing the measurement of the thickness of the boiler water wall pipeline wall and solving the problem of low measurement efficiency in the prior art, improving the measurement efficiency and reducing the labor cost.

[0037] Further, the telescopic mechanism 130 is a lead screw nut mechanism, the telescopic rod 132 is a lead screw, and the bearing seat 131 is a nut matched with the lead screw.

[0038] It can be understood that the nut and the screw rod of the screw nut mechanism are connected through threads, and the screw rod can be moved along the length direction of the screw rod through the rotation of the inner thread of the nut.

[0039] In this way, the position of the telescopic rod can be accurately adjusted by the bearing seat.

[0040] Further, the other end of the telescopic rod 132 of the three telescopic mechanisms 130 is respectively provided with a thickness measuring mechanism 140, an applying mechanism 150 and a polishing mechanism 160.

[0041] In this way, the unit distance required for the boiler water wall pipeline wall thickness measuring device to measure thickness can be shortened.

[0042] Further, the four controllable rotating shafts 121 form a square structure.

[0043] In this way, the boiler water wall pipeline wall thickness measuring device can make the change in the torque size borne by the controllable rotating shaft on the electromagnetic plate in contact with the water wall pipeline relatively flat during the turning movement, thereby improving the stability of the device during the turning movement.

[0044] Further, the cylindrical main body 110 is further provided with a camera.

[0045] In this way, the polishing situation of the position to be polished of the boiler water wall pipeline can be observed by the thickness measuring personnel.

[0046] Further, the cylindrical main body 110 is further provided with a wireless communication module, which is used to receive control signals and send measurement data.

[0047] For example, the wireless communication module can be any one of a wifi module, a Bluetooth module and an infrared module, and no limitation is made thereto.

[0048] In this way, the boiler water wall pipeline wall thickness measuring device can be controlled and the corresponding thickness measurement data can be received through the wireless communication module, so as to facilitate measurement and recording and improve the thickness measuring efficiency.

[0049] Each of the embodiments in the specification is described in a progressive manner, and the same or similar parts between each of the embodiments can be referred to each other, and each of the embodiments mainly describes the difference from other embodiments.

[0050] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still make modifications to the technical solutions described in the foregoing embodiments, or equivalently replace some or all of the technical features thereof, and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
