Description
Technical Field
[0001] This invention relates to the field of generator-related equipment technology, and in particular to a maintenance platform for thermal power plants. Background Technology
[0002] A thermal power plant, or coal-fired power plant for short, is a factory that uses combustible materials as fuel to produce electricity. Its basic production process involves fuel burning to heat water and generate steam, converting the chemical energy of the fuel into heat energy. The steam pressure drives a turbine to rotate, converting the heat energy into mechanical energy. The turbine then drives a generator to rotate, converting the mechanical energy into electrical energy. To maintain the normal operation of a thermal power plant, regular maintenance of various equipment is required. For larger and taller equipment, maintenance platforms are used. Existing platforms often use single hydraulic or simple mechanical support structures, which are prone to swaying and tipping under heavy loads or at height due to uneven ground and shifting center of gravity. For example, traditional scissor lifts rely on fixed supports and cannot dynamically adapt to the support needs of complex working conditions; conventional platforms rely on external cranes or manual handling equipment and lack integrated handling modules. Horizontal movement often relies on wheeled or rail devices, which have poor flexibility in narrow spaces or areas with dense obstacles, and cannot achieve simultaneous lifting and transport operations. In view of the above problems, there may already be technical means to solve them in the prior art, but this case aims to provide an alternative or replacement technical solution. Summary of the Invention
[0003] The technical solution of the present invention to achieve the above objectives is as follows: a maintenance platform for a thermal power plant, comprising: a U-shaped support base, a mover, two pairs of hydraulic supports, a scissor-type support assembly, a lifting and rotating platform, a lifting structure, and a transport and adjustment structure. The mover is installed on the U-shaped support base, the two pairs of hydraulic supports are installed on the U-shaped support base, the scissor-type support assembly is installed on the U-shaped support base and the lifting and rotating platform via the lifting structure, and the transport and adjustment structure is installed on the lifting and rotating platform. The transport and adjustment structure includes: a transport bracket, two pairs of transport winches, a concave lifting limit block, three eye-shaped horizontal telescopic blocks, six pairs of horizontal telescopic wheels, multiple horizontal telescopic rollers, and an auxiliary sealing support assembly. The transport bracket is installed on the lifting and rotating platform, two pairs of transport winches are installed on the transport bracket, the concave lifting limit block is connected to the two pairs of transport winches, and the concave lifting limit block slide is inserted into the inner side of the lifting and rotating platform. The concave lifting limit block has two pairs of convex telescopic holes and one pair of convex telescopic grooves. Six pairs of horizontal telescopic wheels are respectively installed on three eye-shaped horizontal telescopic blocks, and the six pairs of horizontal telescopic wheels are respectively movably inserted into the inner side of one pair of convex telescopic grooves and two pairs of convex telescopic holes. Multiple horizontal telescopic rollers are evenly inserted into three eye-shaped horizontal telescopic blocks. The auxiliary sealing support assembly is installed on the lifting and rotating platform. It should be noted that, as described above, the device moves stably to the U-shaped support base, and the lifting structure and scissor-type support assembly on the U-shaped support base drive the lifting platform to move stably. The lifting platform then drives the transport support to move stably, which in turn drives the two pairs of transport winches. The two pairs of transport winches then drive the concave lifting limit block to move stably. The cooperation of a pair of convex telescopic grooves and two pairs of convex telescopic holes on the concave lifting limit block drives the six pairs of horizontal extensions within it. The retractable metal stabilizer lifts and lowers via six pairs of horizontal telescopic wheels that drive three eye-shaped horizontal telescopic blocks for stable lifting and lowering. When transporting goods, the eye-shaped horizontal telescopic blocks on both sides extend and retract horizontally, causing one pair of horizontal telescopic wheels to extend and retract through convex telescopic holes. This causes another pair of horizontal telescopic wheels on the eye-shaped horizontal telescopic block to rotate, thus bringing the eye-shaped horizontal telescopic block into tight contact with the ground. Simultaneously, the middle eye-shaped horizontal telescopic block extends and retracts horizontally, thereby changing the horizontal support effect and allowing the goods to move and retract horizontally along the horizontal telescopic rollers on the eye-shaped horizontal telescopic blocks.
[0004] Preferably, the auxiliary sealing support assembly includes: two pairs of convex telescopic support blocks, two pairs of support electromagnets, two pairs of support magnets, multiple support limiting shafts, and multiple support linear bearings; The lifting and lowering platform is provided with two pairs of convex telescopic support slots. The two pairs of convex telescopic support blocks are respectively movably inserted into the inner side of the two pairs of convex telescopic support slots. The two pairs of support electromagnets are respectively installed on the inner side of the two pairs of convex telescopic support slots. The two pairs of support magnets are respectively installed on the two pairs of convex telescopic support blocks. Multiple support limiting shafts are evenly inserted into the inner side of the two pairs of convex telescopic support slots, and the multiple support limiting shafts are respectively movably inserted into the two pairs of convex telescopic support blocks. Multiple support linear bearings are respectively inserted into the two pairs of convex telescopic support blocks. It should be noted that, as described above, the two pairs of convex telescopic support slots on the lifting platform are energized, and the two pairs of support electromagnets magnetically repel the two pairs of horizontal support magnets. The horizontal support magnets drive the convex telescopic support blocks on them, causing the convex telescopic support blocks to move to the bottom of the concave lifting limit block. The support limit shaft and the support linear bearing provide stable horizontal telescopic support for the convex telescopic support blocks.
[0005] Preferably, the lifting structure includes: two pairs of concave lifting blocks, two pairs of lifting threaded rods, two pairs of lifting threaded tubes, two pairs of convex lifting blocks, two pairs of lifting gears, a lifting gear rack, a lifting drive motor, a lifting drive gear, four pairs of concave limiting blocks, four pairs of convex limiting blocks, four pairs of concave bearing blocks, four pairs of telescopic gears, multiple telescopic shafts, four pairs of telescopic electromagnets, four pairs of telescopic magnets, a locking assembly, and an auxiliary lifting assembly; Two pairs of concave lifting blocks are evenly inserted into a U-shaped support base. Two pairs of convex lifting blocks are movably inserted into the inner sides of the two pairs of concave lifting blocks. A U-shaped drive groove is provided on the U-shaped support base. Two pairs of lifting threaded rods are respectively inserted into the two pairs of concave lifting blocks and the U-shaped drive groove. Two pairs of lifting threaded tubes are respectively inserted into the two pairs of convex lifting blocks, and the two pairs of lifting threaded tubes are movably fitted onto the two pairs of lifting threaded rods. Two pairs of lifting gears are respectively installed on the two pairs of lifting threaded rods. The lifting drive motor is installed inside the U-shaped drive groove. The lifting drive gear is installed on the drive end of the lifting drive motor. The lifting rack is fitted onto the two pairs of lifting gears and the lifting drive gear. Above, four pairs of concave limiting blocks are installed on the inner side of the U-shaped drive groove, four pairs of convex limiting blocks are respectively movably inserted into the inner side of the four pairs of concave limiting blocks, four pairs of concave bearing blocks are respectively installed on the four pairs of convex limiting blocks, four pairs of telescopic gears are respectively installed on the four pairs of concave bearing blocks, multiple telescopic shafts are respectively inserted into the inner side of the four pairs of concave limiting blocks, and multiple telescopic shafts are respectively movably inserted into the four pairs of convex limiting blocks, four pairs of telescopic magnets are respectively installed on the four pairs of convex limiting blocks, four pairs of telescopic electromagnets are respectively installed on the inner side of the four pairs of concave limiting blocks, the auxiliary lifting assembly is installed on the scissor-type bracket assembly, and the locking assembly is installed on two pairs of concave lifting blocks and the auxiliary lifting assembly; It should be noted that, as described above, the operation of the lifting drive motor drives the lifting drive gear on the drive end of the lifting drive motor. The lifting drive gear drives the lifting assembly rack that meshes with it to rotate. The lifting assembly rack drives the two pairs of lifting gears on it to rotate. The telescopic electromagnet inside the concave limiting block is energized. The telescopic electromagnet magnetically repels the telescopic magnet, which in turn drives the convex limiting block on it. This causes the convex limiting block to stably extend and retract horizontally along the inner side of the concave limiting block. The convex limiting block then drives the concave bearing on it. The block, through the concave bearing block, drives the telescopic gear on it. The telescopic gear squeezes the lifting kit rack, thereby squeezing the lifting kit rack and the lifting gear, thus achieving gear meshing. Two pairs of rotating lifting gears drive the lifting threaded rods on them, which in turn drive the lifting threaded tubes on them. The two pairs of lifting threaded tubes then drive the convex lifting blocks on them, causing the two pairs of convex lifting blocks to rise and fall stably along the inner sides of the two pairs of concave lifting blocks. This, in conjunction with the scissor-type support assembly, enables stable lifting and falling.
[0006] Preferably, the auxiliary lifting assembly includes: eight pairs of loop-shaped limit blocks, four pairs of horizontal telescopic plates, two pairs of horizontal pushing hydraulic push rods, and multiple horizontal telescopic wheels; Eight pairs of the spiral-shaped limiting blocks are installed on the U-shaped support base. Four pairs of the horizontal telescopic plates are movably inserted into the inner side of the eight pairs of spiral-shaped limiting blocks. Multiple horizontal telescopic wheels are respectively on the four pairs of horizontal telescopic plates, and multiple horizontal telescopic wheels are movably inserted into the inner side of the eight pairs of spiral-shaped limiting blocks. Two pairs of horizontal pushing hydraulic push rods are installed on the U-shaped support base, and the pushing ends of the two pairs of horizontal pushing hydraulic push rods are connected to a pair of scissor-type bracket groups. It should be noted that, in the above process, the horizontal extension and retraction of the hydraulic push rod drives the horizontal extension plate on the push end, which in turn drives the scissor bracket assembly on it to retract horizontally. At the same time, multiple horizontal extension wheels on the horizontal extension plate stabilize the horizontal extension and retraction inside the loop-shaped limit block.
[0007] Preferably, the locking assembly includes: multiple locking shaft tubes, multiple locking shaft rods, multiple locking electromagnets, and multiple locking magnets; Multiple locking shaft tubes are evenly inserted into two pairs of concave lifting blocks and eight pairs of loop-shaped limiting blocks. Multiple locking shaft rods are movably inserted into the inner side of multiple locking shaft tubes. Multiple locking electromagnets are installed on the inner side of multiple locking shaft tubes. Multiple locking magnets are installed on multiple locking shaft rods. It should be noted that, as described above, by energizing the locking electromagnet inside the locking shaft tube, the locking electromagnet magnetically repels the locking magnet, and the locking magnet, in turn, causes the locking shaft rod on it to stably extend and retract horizontally along the inner side of the locking shaft tube.

[0022] According to the appendix Figure 1-5It is concluded that the U-shaped support base 1 on the mover is moved stably, and the lifting structure and scissor-type support group 2 on the U-shaped support base 1 are operated, driving the lifting and lowering of the lifting and lowering platform 3 on it. The lifting and lowering platform 3 drives the transport support 1001 on it to move stably, and the transport support 1001 drives the two pairs of transport winches 1002 on it to operate. The operation of the two pairs of transport winches 1002 drives the concave lifting limit block 1003 on it to move stably. Through the cooperation of a pair of convex telescopic grooves and two pairs of convex telescopic holes on the concave lifting limit block 1003, the six pairs of horizontal telescopic wheels 1005 inside it are driven to move stably. The six pairs of horizontal telescopic wheels 1005 drive the three The horizontal telescopic block 1004 is raised and lowered stably. When transporting goods, the horizontal telescopic blocks 1004 on both sides extend and retract horizontally, causing a pair of horizontal telescopic wheels 1005 to extend and retract through convex telescopic holes. This allows another pair of horizontal telescopic wheels 1005 on the horizontal telescopic block 1004 to rotate, thus bringing the horizontal telescopic block 1004 into close contact with the ground. Simultaneously, the middle horizontal telescopic block 1004 extends and retracts horizontally, thereby changing the horizontal support effect and allowing the goods to extend and retract horizontally along the horizontal telescopic rollers on the horizontal telescopic block 1004. By energizing the support electromagnets inside the two pairs of convex telescopic support slots on the lifting platform 3, the two pairs of support electromagnets respectively... Two pairs of horizontal support magnets repel each other magnetically, driving the convex telescopic support blocks on them to move to the bottom of the concave lifting limit block 1003. The convex telescopic support blocks are then stably horizontally supported by the support limit shaft and the support linear bearing. The lifting drive motor 3006 operates, driving the lifting drive gear 3007 on its drive end. The lifting drive gear 3007 drives the lifting assembly rack 3005, which in turn rotates, causing the two pairs of lifting gears 3004 on it to rotate. This energizes the telescopic electromagnet inside the concave limit block 3008, which magnetically repels the telescopic magnets. The convex limiting block on the concave limiting block 3008 is driven to stably extend and retract horizontally along the inner side of the concave limiting block 3008. The convex limiting block drives the concave bearing block on it, which in turn drives the telescopic gear on it. The telescopic gear presses against the lifting sleeve rack 3005, thereby pressing the lifting sleeve rack 3005 against the lifting gear 3004, thus achieving gear meshing. The two pairs of rotating lifting gears 3004 drive the lifting threaded rods 3002 on them, which in turn drive the lifting threaded tubes on them. The two pairs of lifting threaded tubes drive the convex lifting blocks 3003 on them, so that the two pairs of convex lifting blocks 3003 support the linear bearings along the two pairs of concave lifting blocks.The inner side of 3001 performs stable lifting and lowering, thus cooperating with the scissor-type support assembly 2 for stable lifting and lowering; by horizontally pushing the hydraulic push rod to extend and retract, it drives the horizontal telescopic plate on the push end, which in turn drives the scissor-type support assembly 2 to horizontally retract. Simultaneously, multiple horizontal telescopic wheels 1005 on the horizontal telescopic plate perform stable horizontal extension and retraction within the loop-shaped limit block; by energizing the locking electromagnet inside the locking shaft tube, the locking electromagnet magnetically repels the locking magnet, which in turn causes the locking shaft rod above it to stably extend and retract horizontally along the inner side of the locking shaft tube.
