Technical Field

[0001] This utility model relates to the field of boiler inspection technology, and more specifically, to a boiler inspection device. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. There are many types of boilers. According to their uses, boilers can be divided into: power plant boilers, industrial boilers, domestic boilers and special boilers.

[0003] Currently, during the manufacturing process of boilers on the market, it is often necessary to inspect the boiler body for external dents and cracks to ensure that the boiler can proceed with subsequent reprocessing. However, existing boiler inspection equipment often has the following technical problems when inspecting the boiler body:

[0004] In other words, existing boiler inspection equipment cannot simultaneously and comprehensively photograph and detect dents and cracks on the outer surface of the boiler body when inspecting external dents and cracks, which reduces the effectiveness of photographic detection of dents and cracks on the boiler body surface during the processing. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a boiler inspection device that can realize all-round imaging detection of dents and cracks on the surface of boiler body during the processing, thereby improving the effect of imaging detection of dents and cracks on the surface of boiler body during the processing.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A boiler inspection device includes a cylinder assembly, wherein an inspection component is slidably disposed inside the cylinder assembly.

[0008] The inspection assembly includes a lifting component and an inspection component that is slidably fitted on the lifting component, and the inspection component is slidably fitted with the cylinder assembly.

[0009] The cylindrical assembly includes a positioning cylinder, and a spiral groove is formed through the outer peripheral side of the positioning cylinder.

[0010] The lifting component includes a lifting ring that slides inside the positioning cylinder, and both the upper and lower ends of the lifting ring are provided with annular grooves.

[0011] The inspection piece includes a sliding rod that slides on a spiral channel. One end of the sliding rod is fixed with a C-shaped plate, and two symmetrical U-shaped frames are fixed on the side of the C-shaped plate. Guide balls are provided inside the two U-shaped frames, and the two guide balls slide in contact with two annular grooves respectively.

[0012] The present invention is further configured such that an arc-shaped limiting plate is fixed to the outer wall of the C-shaped plate.

[0013] The outer wall of the lifting ring is provided with an annular limiting groove, which slides in conjunction with the arc-shaped limiting plate.

[0014] The present invention is further configured such that: an L-shaped positioning plate is fixed to the bottom of the lifting ring, and a fixing sleeve is fixed to the bottom of the L-shaped positioning plate.

[0015] A positioning ring seat is fixed at the bottom of the positioning cylinder.

[0016] The present invention is further configured such that: two symmetrical connecting plates are fixed on the inner wall of the positioning cylinder near the bottom, and a placement platform is fixed between the two connecting plates, the height of which is higher than the starting end of the spiral channel.

[0017] The present invention is further configured such that: an installation plate is fixed to the inner wall of the positioning cylinder near the bottom, a telescopic cylinder is fixed to the top of the installation plate, and the telescopic end of the telescopic cylinder is fixedly connected to the fixed sleeve.

[0018] The present invention is further configured such that: the inspection piece also includes an L-shaped fixing plate fixedly installed on the top of the C-shaped plate, the top of the L-shaped fixing plate having two symmetrical limiting grooves through it, both limiting grooves having a sliding limiting vertical plate inside them, both limiting vertical plates having a clamping side plate fixed on their tops, both clamping side plates having a rubber protective plate fixed on one side opposite to the other, and a camera inspection device being clamped and positioned between the two rubber protective plates.

[0019] The present invention is further configured such that a displacement side plate is fixed at the bottom of both of the limiting vertical plates.

[0020] A vertical baffle is fixed to the side of the L-shaped fixing plate, and two symmetrical side baffles are fixed to the side of the vertical baffle. A bidirectional threaded screw is rotatably connected between the two side baffles via a bearing. A first fitting circular plate that fits against the side of one of the side baffles is fixed to one end of the bidirectional threaded screw, and a second fitting circular plate that fits against the side of the other side baffle is fixed to the other end of the bidirectional threaded screw. A rotating disk is fixed to one end of the bidirectional threaded screw, and a fastening bolt that rotatably fits against the thread of one of the side baffles is threaded through one side of the rotating disk. Both displacement side plates are rotatably connected to the bidirectional threaded screw.

[0021] The advantages of this utility model are: 1. This utility model uses the up-and-down movement of the lifting component inside the positioning cylinder, combined with the sliding process of the sliding rod on the spiral groove opened on the circumferential side of the positioning cylinder, to drive the entire inspection piece to move up and down while simultaneously rotating circumferentially on the lifting component. In the whole process, it realizes all-round imaging detection of the surface of the boiler body during the processing, thereby improving the effect of imaging detection of the surface of the boiler body during the processing.

[0022] 2. This utility model, by rotating the bidirectional threaded screw, causes the rubber protective plate fixed on one side of the two clamping side plates to come into contact with the opposite sides of the camera inspection device, thus preventing the camera inspection device from becoming loose during the subsequent inspection of the boiler body surface for dents and cracks during the processing, which would affect the subsequent dent and crack inspection process.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0035] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0036] Example 1, please refer to Figure 1-9 The present invention provides the following technical solution:

[0037] Specifically, it refers to a boiler inspection device, including a cylinder assembly 1, with an inspection component 2 slidably disposed inside the cylinder assembly 1; the inspection component 2 includes a lifting component 3 and an inspection component 4 slidably fitted on the lifting component 3, the inspection component 4 being slidably fitted with the cylinder assembly 1; the cylinder assembly 1 includes a positioning cylinder 101, with a spiral groove 102 penetrating through the outer periphery of the positioning cylinder 101; the lifting component 3 includes a lifting ring 301 slidably fitted inside the positioning cylinder 101, with annular grooves 302 at both the upper and lower ends of the lifting ring 301; the inspection component 4 includes a sliding rod 401 slidably fitted on the spiral groove 102, with a C-shaped plate 402 fixed to one end of the sliding rod 401, and two symmetrical U-shaped frames 403 fixed to the side of the C-shaped plate 402, each of the two U-shaped frames 403 having a guide ball 404 inside, the two guide balls 404 being slidably fitted with the two annular grooves 302 respectively;

[0038] Furthermore, an arc-shaped limiting plate 405 is fixed to the outer wall of the C-shaped plate 402; an annular limiting groove 303 is provided on the outer wall of the lifting ring 301, and the annular limiting groove 303 slides in cooperation with the arc-shaped limiting plate 405; an L-shaped positioning plate 304 is fixed to the bottom of the lifting ring 301, and a fixing sleeve 305 is fixed to the bottom of the L-shaped positioning plate 304; a positioning ring seat 103 is fixed to the bottom of the positioning cylinder 101.

[0039] The specific application of this embodiment is as follows: When it is necessary to perform video inspection of dents and cracks on the surface of the boiler body during the processing, the lifting component 3 moves back and forth inside the positioning cylinder 101 during the lifting process of the lifting component 3. This causes the lifting ring 301 fixed to the top of the L-shaped positioning plate 304 to move back and forth inside the positioning cylinder 101. When the lifting ring 301 fixed to the top of the L-shaped positioning plate 304 moves back and forth inside the positioning cylinder 101, the sliding process of the sliding rod 401 in the inspection component 4 on the spiral groove 102 penetrating the circumferential side of the positioning cylinder 101 drives the sliding fit on the lifting component 3 to move back and forth. The inspection piece 4 on piece 3 reciprocates and rotates circumferentially inside the positioning cylinder 101. Through the matching process between the guide balls 404 rotating on the two U-shaped frames 403 and the two annular grooves 302, the arc-shaped limiting plate 405 fixed to the inner wall of the C-shaped plate 402 slides synchronously inside the annular limiting groove 303. Finally, the entire inspection piece 4 rotates circumferentially on the lifting piece 3 simultaneously while it is moving up and down. The whole process realizes all-round imaging detection of dents and cracks on the surface of the boiler body during the processing, thereby improving the effect of imaging detection of dents and cracks on the surface of the boiler body during the processing.

[0040] Example 2, please refer to Figure 1-9This second embodiment is an improvement on the first embodiment. Specifically, two symmetrical connecting plates 104 are fixed to the inner wall of the positioning cylinder 101 near the bottom. A placement platform 105 is fixed between the two connecting plates 104, and the height of the placement platform 105 is higher than the starting end of the spiral channel 102. An installation plate 106 is fixed to the inner wall of the positioning cylinder 101 near the bottom. A telescopic cylinder 107 is fixed to the top of the installation plate 106, and the telescopic end of the telescopic cylinder 107 is fixedly connected to the fixed sleeve 305. The inspection piece 4 also includes an L-shaped fixing plate 406 fixedly installed on the top of the C-shaped plate 402. Two symmetrical limiting grooves 407 are opened through the top of the L-shaped fixing plate 406. Limiting vertical plates 408 are slidably fitted inside the two limiting grooves 407. Clamping side plates 409 are fixed to the top of the two limiting vertical plates 408. Rubber protective plates 4 are fixed to the opposite side of the two clamping side plates 409. 10. A camera inspector 411 is clamped and positioned between two rubber protective plates 410; displacement side plates 412 are fixed to the bottom of both limiting vertical plates 408; a vertical baffle 413 is fixed to the side of an L-shaped fixing plate 406, and two symmetrical baffles 414 are fixed to the side of the vertical baffle 413. A bidirectional threaded screw 415 is rotatably connected between the two baffles 414 via a bearing. A first fitting round plate 416 that fits against the side of one baffle 414 is fixed to one end of the bidirectional threaded screw 415, and a second fitting round plate 417 that fits against the side of the other baffle 414 is fixed to the other end of the bidirectional threaded screw 415. A rotating disk 418 is fixed to one end of the bidirectional threaded screw 415, and a fastening bolt 419 that fits rotatably against the thread of one baffle 414 is threaded through one side of the rotating disk 418. Both displacement side plates 412 are rotatably connected to the bidirectional threaded screw 415.

[0041] A specific application of this embodiment is as follows: Before performing video inspection of the surface of the boiler body during the processing to detect dents and cracks, the video inspector 411 is placed on the outer top of the L-shaped fixed plate 406. After placement, the bidirectional threaded screw 415 is rotated, causing the two displacement side plates 412 connected to the circumferential side of the bidirectional threaded screw 415 to move synchronously closer to each other. When the two displacement side plates 412 move synchronously closer to each other on the circumferential side of the bidirectional threaded screw 415, the sliding engagement of the limiting vertical plates 408 fixed to the top of the two displacement side plates 412 within the two limiting grooves 407, respectively, controls the movement of the two limiting vertical plates 408. The clamping side plates 409 move towards the opposite sides of the camera inspector 411 in a synchronized manner until the rubber protective plates 410 fixed on the opposite side of the two clamping side plates 409 are in contact with the opposite sides of the camera inspector 411. Then, the rotating disk 418 fixed at one end of the bidirectional threaded screw 415 is stopped from rotating and fixed by the threaded rotation between the fastening bolt 419 and the side baffle 414. This limits and fixes the bidirectional threaded screw 415 to prevent it from becoming loose when the camera inspector 411 is used to detect dents and cracks on the surface of the boiler body during the processing, which would affect the subsequent dent and crack detection process.

[0042] When it is necessary to perform video inspection on the surface of the boiler body during the processing, the boiler body during the processing is first hoisted onto the top of the placement platform 105 fixed between the two connecting plates 104, so that the boiler body during the processing is placed on the top of the placement platform 105, so that the camera inspection device 411 can perform video inspection on the outer surface of the boiler body during the processing to detect dents and cracks (the camera inspection device 411 takes pictures of the outer surface of the boiler body, and transmits the pictures to the computer so that the staff can use the pictures to judge the dents and cracks on the outer surface of the boiler body. The process of the camera inspection device 411 detecting dents and cracks and transmitting the pictures to the computer is existing technology and will not be described in detail here).

[0043] The telescopic cylinder 107 is fixedly connected to the fixed sleeve 305, which drives the telescopic cylinder 107 to move back and forth, so as to provide power for the spiral back and forth lifting and lowering detection process of the inspection piece 4 (the back and forth lifting and lowering movement of the telescopic cylinder 107 can be realized by an external controller, which is existing technology and is not shown in the figure, so it will not be elaborated here). This facilitates the subsequent use of the camera inspection device 411 in the inspection piece 4 to perform all-round camera inspection of the surface of the boiler body during the processing, thereby improving the effect of camera inspection of the surface of the boiler body during the processing.
