Description

Technical Field

[0001] This invention relates to the field of electric suspended platform technology, specifically a combined electric suspended platform for furnace interior inspection. Background Technology

[0002] In thermal power plants, boiler maintenance and cleaning are essential. These structures are typically located at high elevations and require regular inspection and repair of the water-cooled walls, especially after emergency shutdowns. Boiler maintenance necessitates the erection of steel scaffolding within the boiler furnace, which is time-consuming, labor-intensive, and resource-intensive.

[0003] Therefore, a suspended platform is needed for boiler internal maintenance, which saves time and manpower. However, the existing suspended platforms are one-piece platforms with large dimensions. When using them, the platforms need to be moved to a designated location first, wasting a lot of manpower. After use, they are inconvenient to store, taking up a lot of space. Boilers require regular maintenance and inspection, making their use and storage extremely inconvenient. Furthermore, when inspecting the boiler's interior, the lighting is insufficient, requiring workers to manually use lighting tools, which is a heavy burden on them. The lighting tools are also not bright enough. During the maintenance process, the problematic inner walls need to be repaired, and the repair tools require electricity. The existing suspended platforms do not have a power supply function, requiring the use of power lines, which results in long power lines that are prone to damage. Summary of the Invention

[0033] Please see Figure 1-6 The present invention provides a technical solution.

[0034] Example 1:

[0035] Please see the appendix Figure 1-6 In the specific implementation process, the furnace interior is inspected by a combined electric hoist, which includes: the hoist body 1 and a multi-functional structure, with the multi-functional components installed on the hoist body 1;

[0036] The multifunctional structure includes: a power supply component, a winding component, and a lighting component;

[0037] The power supply assembly is installed on the suspended platform body 1, the winding assembly is installed on the suspended platform body 1, and the lighting assembly is installed on the suspended platform body 1;

[0038] The suspended platform body 1 includes: a base 2, a support column 3, a connecting assembly, a protective plate 4, a protective door 5, a cable 6, an electric hoist 7, a synchronizer 8, and a locking assembly;

[0039] The support column 3 is installed on the four corners of the base 2 via connecting components. The protective plate 4 is installed on the support column 3. The protective door 5 is installed on the support column 3. The electric hoist 7 is installed on the support column 3. The synchronizer 8 is installed on the electric hoist 7. The locking component is installed on the protective door 5.

[0040] It should be noted that when the boiler needs to be inspected, the prefabricated suspended basket needs to be assembled. The main body 1 of the suspended basket is fixed to the base 2 by the connecting components, thus fixing the basic frame of the suspended basket. A protective plate 4 is installed on the support column 3 to enclose the suspended basket and prevent personnel or internal equipment from falling. The protective door 5 installed on the support column 3 facilitates personnel entry and exit. The height of the suspended basket is adjusted by the electric hoist 7 installed on the support column 3 and the cable 6 installed on the electric hoist 7. At the same time, the synchronizer 8 installed on the electric hoist 7 starts and stops the electric hoists 7 installed on both sides of the suspended basket synchronously. When working at height, in order to prevent the protective door 5 from opening, the protective door 5 is locked by the locking component to prevent personnel from falling. After use, the suspended basket can be disassembled into parts for easy storage and to save space.

[0041] Preferably, the base 2 is further provided with a counterweight.

[0042] It should be noted that the base 2 is equipped with a counterweight, which facilitates the adjustment of the load-bearing point of the suspended basket and can effectively prevent the suspended basket from tilting and causing personnel to fall.

[0043] Preferably, the connecting assembly further includes: a limiting block 9, a connecting block 10, a bolt 11, a nut 12, a slider 13, and a sliding groove 14;

[0044] The sliding groove 14 is opened on the four corners of the base 2, the connecting block 10 is installed at the bottom of the support column 3, the limiting block 9 is installed at the four corners of the base 2, the slider 13 is installed on the support column 3, the bolt 11 is embedded in the base 2, and the nut 12 is installed on the bolt 11.

[0045] It should be noted that the slider 13 installed on the support column 3 is inserted into the sliding groove 14 opened on the base 2 to guide the support column 3. After the support column 3 is installed in place, the connecting block 10 installed on the support column 3 is pressed against the limiting block 9 installed on the base 2. The bolt 11 is inserted into the base 2 and passes through the slider 13. The nut 12 is installed on the bolt 11 to complete the fixing of the base 2 and the support column 3. This makes the fixing more secure and easier to install and disassemble.

[0046] Preferably, a groove is provided at the connection between the protective plate 4 and the support column 3.

[0047] It should be noted that a sliding groove is provided at the connection between the protective plate 4 and the support column 3, which facilitates the installation of the protective plate 4 onto the support column 3.

[0048] Preferably, and further still, the locking assembly includes: a moving block 15, a grip 16, a latch 17, and a locking block 18;

[0049] Movable block 15 is installed on protective door 5, handle 16 is installed on movable block 15, buckle 17 is installed on movable block 15, and latch 18 is installed on support column 3.

[0050] It should be noted that the frame of the protective door 5 is installed on the support column 3. After personnel enter the basket, they push the handle 32 installed at the top of the protective door 5. Under the action of the handle 32, the moving block 15 connected to the handle 32 is pushed into the support column 3, completing the initial locking. In order to prevent the protective door 5 from coming out during operation, a buckle 17 is provided on the moving block 15. When the moving block 15 moves to the support column 3, the buckle 18 installed on the moving block 15 and the buckle 18 installed on the support column 3 are engaged with each other to lock the moving block 15. The lock is then embedded in the exposed buckle 18 to complete the final locking. This can effectively prevent the protective door 5 from opening during operation, which could lead to personnel injury or death.

[0051] Preferably, the protective door 5 is further provided with a groove of the same size as the movable block 15.

[0052] It should be noted that the protective door 5 is provided with a sliding groove of the same size as the movable block 15, which facilitates the movement of the movable block 15.

[0053] Preferably, the power supply assembly includes: a diesel generator 19, a transformer 20, a winding assembly, and a power supply line 21;

[0054] The diesel generator 19 is installed on the base 2 on the side opposite to the protective door 5. The transformer 20 is installed on the base 2 on the side of the diesel generator 19. The power supply line 21 is installed on the winding assembly and connected to the transformer 20.

[0055] It should be noted that during operation, after the personnel detect the location that needs to be processed, they start the diesel generator 19 installed on the base 2. The diesel generator 19 generates electrical energy, which is transmitted to the transformer 20. The transformer 20 stabilizes the output value of the electrical energy. The transformed electrical energy is then transmitted to the workpiece that needs to be used through the power supply line 21 connected to the transformer 20 and the winding assembly. This eliminates the need for an external power supply to power the basket, effectively preventing the dangers caused by excessively long external lines.

[0056] As a preferred and further embodiment, the winding assembly comprises: a support frame 22, a rotating shaft 23, a rotating handle 2416, a roller 25, a gear 26, a spring 27, a fixing block 28, and a connecting shaft 29.

[0057] The support frame 22 is mounted on the base 2, the rotating shaft 23 is mounted on the support frame 22, the roller 25 is mounted on the rotating shaft 23, the rotating handle 2416 is mounted on the rotating shaft 23, the gear 26 is mounted on the rotating shaft 23, the connecting shaft 29 is mounted on the support frame 22, the fixing block 28 is mounted on the connecting shaft 29, and the spring 27 is mounted on the support frame 22 and connected to the rear end of the fixing block 28.

[0058] It should be noted that when the power supply cable 21 is needed to provide power to the equipment, one end of the power supply cable 21 is pulled outward. Under the action of the pulling force, the power supply cable 21, which is mounted on the roller 25, extends outward around the rotating shaft 23, making it easier for personnel to use. At the same time, the length of the power supply cable 21 can be effectively limited. During the rotation of the roller 25, the connecting shaft 29 will be driven to rotate. Under the action of the rotation of the connecting shaft 29, the gear 26 mounted on the connecting shaft 29 will be driven to rotate. Under the rotation of the gear 26, the teeth on the gear 26 will collide with the fixed block 28, which will push the fixed block 28 upward. The fixing block 28 rotates around the connecting shaft 29. Under the action of the fixing block 28, the spring 27, which is connected to the tail end of the fixing block 28 and is mounted on the support frame 22, is compressed. After the protruding teeth rotate, under the action of the spring 27, the fixing block 28 will be engaged into the gear 26 again. This can effectively prevent the connecting shaft 29 from rotating due to inertia under the action of tension, so that the power supply line 21 is too long. After completion, the person needs to manually move the fixing block 28 and rotate the rotating handle 2416 mounted on one end of the rotating shaft 23 in the opposite direction to rewind the power supply line 21 onto the roller 25.

[0059] Preferably, a bearing is provided at the connection between the rotating shaft 23 and the support frame 22.

[0060] It should be noted that a bearing is provided at the connection between the rotating shaft 23 and the support frame 22 to facilitate the rotation of the rotating shaft 23.

[0061] As a preferred and further embodiment, the lighting assembly includes: mounting base 30, lead screw 31, handle 32, clamping block 33, support hose 34, and lighting lamp 35;

[0062] Mounting base 30 is mounted on protective plate 4, lead screw 31 is embedded in mounting base 30, clamping block 33 is mounted on one end of lead screw 31, handle 32 is mounted on the other end of lead screw 31, support hose 34 is mounted on mounting base 30, and lighting lamp 35 is mounted on support hose 34.

[0063] It should be noted that due to insufficient lighting inside the furnace, using handheld lighting devices for illumination checks can lead to missed detections. Therefore, by placing the mounting base 30 on the upper end of the protective plate 4 and rotating the handle 32, the screw 31 is rotated. Under the action of the handle 32, the clamping block 33 installed on the screw 31 moves towards the protective plate 4, fixing the mounting base 30 to the protective plate 4. After fixing, the lighting angle of the lighting lamp 35 installed on the support hose 34 can be adjusted by manually adjusting the support hose 30, thereby improving the lighting effect inside the furnace.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
