Technical Field

[0001] This application belongs to the technical field of boiler maintenance auxiliary tools, and more specifically, relates to a support device for boiler maintenance. 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 carriers with a certain amount of thermal energy.

[0003] Existing boilers require regular maintenance during long-term use. Since boilers are generally quite large, support devices are needed to support workers during maintenance. These support devices often use lifting platforms. For example, patent application number 2024213090611 discloses a boiler maintenance auxiliary device that uses a lifting mechanism. However, because the lifting mechanism is often rigidly connected and lacks a fixing device, its stability is poor. This can easily cause the lifting mechanism to sway and pose a danger to maintenance personnel working at heights, making boiler maintenance inconvenient. Utility Model Content

[0004] To address the shortcomings of the existing technology, the purpose of this application is to provide a support device for boiler maintenance, which can use an electromagnet to attract the boiler and increase its stability.

[0028] like Figures 1-6 As shown in the illustration, a boiler maintenance support device provided in this application embodiment will now be described. This boiler maintenance support device includes a lifting platform 100 and a support platform 200. The lifting platform 100 is a conventional scissor-type hydraulic lifting platform 100, which uses a hydraulic lifting bracket for lifting. The support platform 200 is mounted on the lifting platform 100, thereby allowing for height adjustment of the support platform 200 via the lifting platform 100. The bottom of the lifting platform 100 is equipped with at least four rollers 101 to facilitate movement of the entire boiler maintenance support device. The rollers 101 can be equipped with a locking function to ensure stability when stationary.

[0029] The support platform 200 is equipped with a movable connecting device 300 for connecting to the boiler. Connecting the connecting device 300 to the boiler increases the stability and improves safety of the entire boiler maintenance support system. The connecting device 300 is concealed on the support platform 200, only needing to be extended when needed and stored within the support platform 200 when not in use, reducing temporary space requirements and providing protection. The connecting device 300 can be linearly driven for retraction, with a recessed storage groove on one end face of the support platform 200 housing a linear drive mechanism. The connecting device 300 is mounted on the linear drive mechanism, allowing for both retraction and extension, with connection to the boiler upon extension. Alternatively, the connecting device 300 can be rotated for retraction; this embodiment primarily uses a rotating installation method for the connecting device 300 on the support platform 200.

[0030] In this embodiment, the connecting device 300 includes a connecting assembly 310 rotatably mounted on the support platform 200 and an electromagnet 320 mounted on the connecting assembly 310 for magnetic connection with the boiler. The support platform 200 is also provided with a driving device 400 for driving the connecting assembly 310 to move so that the electromagnet 320 on the connecting assembly 310 is magnetically connected with the boiler or to house the connecting device 300 within the support platform 200.

[0031] The drive device 400 includes a drive assembly 410 mounted on the support platform 200 for rotation. The drive assembly 410 includes at least a lead screw 415 rotatably mounted on the support platform 200. An adjustment assembly 420, which is threaded onto the lead screw 415 and hinged to the connecting assembly 310, is used to rotate the connecting assembly 310. When the lead screw 415 rotates, it drives the connecting assembly 310 to rotate via the adjustment assembly 420, thereby causing the connecting assembly 310 to extend or retract onto the support platform 200.

[0032] For safety, a guardrail 201 is installed around the support platform 200. An operating console 202 is located within the area enclosed by the guardrail 201 on the support platform 200. The operating console 202 is used to control the on / off state of the electromagnet 320 and the raising and lowering of the lifting platform 100. For easy access for staff, one side of the guardrail 201 has a hinged gate 203 that can be opened and closed, such as by using a door bolt.

[0033] Specifically, in this embodiment, there are two connecting devices 300, which are respectively arranged on both sides of the support platform 200. The side of the support platform 200 is provided with a long groove 204 for receiving the connecting devices 300.

[0034] Specifically, the connecting assembly 310 includes a connecting plate 311 rotatably disposed at one end within the elongated slot 204, and a groove 313 for mounting an electromagnet 320 at the other end of the connecting plate 311. The shape of the connecting plate 311 can be changed according to actual conditions, such as being arc-shaped or having the end for mounting the electromagnet 320 being L-shaped, so that the electromagnet 320 can better fit or approach the boiler. A hinge block 312 for hinged connection with the adjusting assembly 420 is mounted on the connecting plate 311.

[0035] In this embodiment, the lead screw 415 is driven manually. In other embodiments, the lead screw 415 can also be driven electrically. Specifically, the drive assembly 410 further includes a first bevel gear 413, a second bevel gear 414, a rotating shaft 412, and a handwheel 411. The rotating shaft 412 is rotatably mounted on the support platform 200. The rotating shaft 412 is vertically mounted, with one end located on the surface of the support platform 200 and the other end extending into the long groove 204. The handwheel 411 is located at one end of the rotating shaft 412 and above the upper surface of the support platform 200. The first bevel gear 413 is fixed to the other end of the rotating shaft 412. The lead screw 415 is rotatably mounted in the long groove 204. The second bevel gear 414 is fixed to one end of the lead screw 415, and the first bevel gear 413 and the second bevel gear 414 mesh. When the operator rotates the handwheel 411, it drives the rotating shaft 412 to rotate, which in turn drives the first bevel gear 413 to rotate, and simultaneously drives the second bevel gear 414 to rotate, thereby driving the lead screw 415 to rotate. When the lead screw 415 rotates, it enables the connecting adjustment component 420 to perform linear reciprocating motion. When the adjusting component 420 performs linear reciprocating motion, it drives the connecting plate 311 to rotate, so as to open or close the connecting plate 311.

[0036] Specifically, the adjusting assembly 420 includes a hinge plate 422 and a threaded sleeve plate 421. The threaded sleeve plate 421 is threadedly connected to the lead screw 415. One end of the hinge plate 422 is hinged to the hinge block 312, and the other end is hinged to the threaded sleeve plate 421. The threaded sleeve plate 421 is a rectangular plate that matches the shape of the long groove 204, ensuring that the threaded sleeve plate 421 moves linearly only along the length direction of the lead screw 415.

[0037] When boiler maintenance is required, the hydraulic lifting frame 102 can be controlled by the operating panel 202 to raise the support platform 200 to the position where boiler maintenance is required. The handwheel 411 drives the rotating shaft 412 to rotate, and with the meshing connection between the first bevel gear 413 and the second bevel gear 414, the threaded rod 415 can rotate synchronously with the rotating shaft 412. Therefore, the threaded sleeve plate 421 can move back and forth along the threaded rod 415, and with the connection of the hinge plate 422, the connecting plate 311 can be unfolded from the long slot 204. Then, by moving the roller 101 at the bottom of the lifting platform 100, the support platform 200 can be driven closer to the boiler. Then, by energizing the electromagnet 320, the electromagnet 320 can generate magnetism and be attracted to the boiler. The support platform 200 can be fixed to prevent the support platform 200 from shaking when it is at a height.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
