[0002] The runner of a hydro-turbine generator set is a key component for energy conversion. During the long-term power generation process of a hydropower station, this component will experience problems such as wear and fatigue cracks. Therefore, the runner needs to be regularly inspected and maintained. Currently, the maintenance of the runner of a hydro-turbine generator set is done by first building a maintenance platform and then building a scaffolding on the maintenance platform.

[0005] 2. When the airbag lifting platform is in use, when the worker steps on the uppermost airbag, the airbag has a certain degree of mobility and gravity causes a depression at the stepping point of the airbag, which can easily cause the worker's body to tilt and fall.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 1 to Figure 7, which is the first embodiment of the present invention, and provides a rotary wheel maintenance device using airbags, which can achieve the effect of ensuring the stability of the airbag lifting platform 103 and protecting the safety of workers, and includes an installation component 100, including a pipeline 101, a maintenance platform 102 arranged in the pipeline 101, an airbag lifting platform 103 composed of multiple airbags arranged on the maintenance platform 102, a folding ladder 104 arranged on the airbag lifting platform 103, a bottom plate 105 arranged at the lower end of the airbag lifting platform 103, a plurality of universal wheels 106 arranged on the bottom plate 105, an inlet 107 arranged on the side wall of the pipeline 101, an intelligent air compressor 108 arranged on the outside of the pipeline 101, and a device An air supply pipe 109 is placed on the intelligent air compressor 108; a protective component 200, including an air cushion component 201 arranged at the lower end of the maintenance platform 102, a blocking component 202 arranged on the airbag lifting platform 103, an elastic component 203 arranged on the blocking component 202, a linkage component 204 arranged on the elastic component 203, and a guide component 205 arranged on the blocking component 202; a release component 300, including a toggle component 301 arranged on the blocking component 202, and a threaded component 302 arranged on the toggle component 301; an anti-sway component 400, including an adsorption component 401 arranged on the bottom plate 105, and a pump air component 402 arranged on the threaded component 302.

[0035] Specifically, the pipeline 101 is a pipeline 101 used for repairing the turbine generator set rotor. The horizontal cross-section of the airbag lifting platform 103 is semicircular, and the side is in contact with the inner wall of the pipeline 101. The folding ladder 104 is fixedly connected to the airbag at the uppermost end of the airbag lifting platform 103, and the universal wheel 106 is in contact with the repair platform 102. When installing the repair platform 102, it is necessary to set up the main beam in the pipeline 101, and then set up the repair platform 102.

[0036] Furthermore, the air cushion assembly 201 includes a steel wire rope 201a fixedly connected to the inner wall of the inlet port 107, the lower end of the steel wire rope 201a is fixedly connected to a safety air cushion 201b, an air pump 201c is fixedly connected to the side wall of the pipeline 101 through a supporting plate, and the air pump 201c is provided with a pump air pipe 201d connected to the safety air cushion 201b; the blocking assembly 202 includes a protective fence 202a fixedly connected to the upper end of the airbag lifting platform 103, and a stop plate 202b is fixedly connected to the side wall of the airbag at the upper end of the airbag lifting platform 103.

[0037] Among them, the safety air cushion 201b needs to be placed into the pipe 101 first when building the main beam. The setting of the wire rope 201a here does not require workers to enter the pipe 101 to build the safety air cushion 201b. The protective fence 202a here surrounds the outer end of the airbag lifting platform 103, and the height of the stop plate 202b is equal to the height of the uppermost airbag of the airbag lifting platform 103 when it is inflated.

[0038] Preferably, the elastic component 203 includes a slider 203a disposed on the stop plate 202b, the slider 203a is provided with a mounting groove 203b, a wedge block 203c is slidably connected in the mounting groove 203b, and the wedge block 203c is elastically connected to the inner wall of the mounting groove 203b through a first spring 203d; the linkage component 204 includes an adapter plate 204a fixedly connected to the side wall of the wedge block 203c, and a plurality of limit openings 204b are provided on the protective fence 202a. A limiting rod 204c that cooperates with the limiting opening 204b is fixedly connected to the adapter plate 204a; the guide assembly 205 includes a circular ring 205a fixedly connected to the inner wall of the pipe 101, and a plurality of strip grooves 205b are provided on the circular ring 205a, and arc grooves 205c are provided in the strip grooves 205b, and vertical grooves 205d are provided on the arc grooves 205c. The vertical grooves 205d and the inner walls of the arc grooves 205c are both provided with card grooves 205e that cooperate with the wedge block 203c.

[0039] It should be noted that the wedge block 203c cooperates with the slot 205e to prevent the uppermost airbag (referring to the airbag on the airbag lifting platform 103, the same below) from moving downward. At the same time, the limit rod 204c cooperates with the limit opening 204b to prevent the protective fence 202a from moving downward, thereby preventing the uppermost airbag from being sunken too much and causing unstable stepping by workers. At the same time, the distance between the two slots 205e here is equal to the height of the bulging of a single airbag, so that no matter how many airbags are bulged, it can be ensured that the wedge block 203c can cooperate with the slot 205e. The intelligent air compressor 108 can monitor the air pressure of each layer of the airbag lifting platform 103, and automatically replenish air when the air pressure drops to a certain level. This is the prior art and will not be elaborated here. The provision of multiple strip slots 205b here allows the position of the airbag lifting platform 103 to be interchanged, which is convenient for replacement and maintenance.

[0040] When in use, firstly, the safety air cushion 201b is placed into the pipe 101 through the wire rope 201a from the inlet 107, then the wire rope 201a is fixed, and then the safety air cushion 201b is inflated through the air pump 201c, and then the main beam is built. When building the main beam, even if the workers fall, the safety air cushion 201b will protect the workers and ensure their safety. Then, after the main beam is built, the maintenance platform 102 is placed, and then the airbag lifting platform 103 is built (first put the materials on the maintenance platform 102 through the inlet 107, and then build). When the construction is completed, the airbag lifting platform 103 is inflated. Here, the airbag at the top is inflated first, so that the airbag expands, and the airbag lifting platform 103 rises a little bit. When the airbag lifting platform 103 rises, the slider 203a first enters the vertical groove 205d from the arc groove 205c. In this process, due to the setting of the inclined surface on the wedge block 203c, the wedge block 20 3c is stuck with the card slot 205e. The setting of the arc groove 205c here allows the airbag at the top to have space to extend outward after the airbag lifting platform 103 is completely deflated. When inflating here, a complete airbag is inflated each time, so that each time the wedge block 203c stops, it can enter the card slot 205e. The setting of the first spring 203d here avoids the wedge block 203c from getting stuck when it is upward. When inflated to the required position, the wedge block 20 3c enters into the card slot 205e, so that the stop plate 202b cannot move downward or outward (the outer end of its airbag lifting platform 103 is against the inner wall of the ring 205a and will not expand outward), and at this time the limit rod 204c is stuck in the limit opening 204b, so that the protective fence 202a cannot descend, so that when the worker steps on the uppermost airbag, the airbag will not sink significantly, so that the worker is not likely to tilt his body, ensuring the stability of the worker when stepping.

[0041] In summary, by providing the protective component 200, the shape of the airbag can be maintained, preventing the airbag from being greatly dented when the worker steps on the airbag lifting platform 103, thereby affecting the stability of the worker when standing, thereby ensuring the safety of the worker during maintenance.

[0042] Example 2

[0043] Reference Figure 1 to Figure 7, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a release component 300 of the rotary wheel maintenance device using an airbag, which solves the problem of how to reset the airbag lifting platform 103. It includes a toggle assembly 301, including a mounting cavity 301a arranged on a stop plate 202b, a first rotating shaft 301b and two second rotating shafts 301c passing through and rotatably connected on the stop plate 202b, the second rotating shaft 301c and the first rotating shaft 301b are perpendicular to each other, and the first rotating shaft 301b and the second rotating shaft 301c are fixedly connected with mutually matching bevel gears 30 1d; the threaded assembly 302 includes a housing chamber 302a arranged on the stop plate 202b, a U-shaped frame 302b is sealed and slidably connected in the housing chamber 302a, a second rotating shaft 301c extends into the housing chamber 302a and is rotatably connected to the inner wall of the housing chamber 302a, a threaded rod 302c threadedly connected to the U-shaped frame 302b is fixedly connected to the second rotating shaft 301c, a connecting block 302d is fixedly connected to the U-shaped frame 302b, the slider 203a passes through the stop plate 202b and is sealed and slidably connected to the stop plate 202b, and the connecting block 302d is fixedly connected to the slider 203a.

[0044] Specifically, the threads on the two threaded rods 302c are in opposite directions, so that the two U-shaped frames 302b move toward the middle or to both ends at the same time. The distance between the wedge block 203c and the stop plate 202b is greater than the thickness of the wedge block 203c. Therefore, when the wedge block 203c does not abut against the stop plate 202b, the wedge block 203c can be separated from the slot 205e. At the same time, the width of the wedge block 203c is greater than the depth of the slot 205e, and the adapter plate 204a is fixed to the part of the wedge block 203c extending to the outer end of the slot 205e.

[0045] During use, when the airbag lifting platform 103 needs to be reset, after the worker climbs onto the folding ladder 104, he reaches out to rotate the first rotating shaft 301b. Here, a rotating disk is fixedly connected to the first rotating shaft 301b to rotate the first rotating shaft 301b. Since there is resistance when the first rotating shaft 301b and the second rotating shaft 301c rotate, the first rotating shaft 301b will not rotate by itself. The rotation of the first rotating shaft 301b makes the second rotating shaft 301c rotate through the cooperation of the bevel gear 301d, so that the threaded rod 302c rotates, so that the two ends of the rotating shaft 301b can rotate. The U-shaped frame 302b moves toward the middle, driving the connecting block 302d to move toward the middle, and the slider 203a moves toward the middle, so that the wedge block 203c disengages from the slot 205e. At this time, the uppermost airbag can descend. When it is necessary to stabilize the airbag lifting platform 103, reversing the first rotating shaft 301b can make the slot 205e match the wedge block 203c again. The limiting opening 204b here is a strip, so that when the wedge block 203c moves and drives the adapter plate 204a to move, the limiting rod 204c and the limiting opening 204b will not get stuck.

[0046] In summary, by setting the release component 300, when the airbag lifting platform 103 is deflated and stored, it is only necessary to rotate the first rotating shaft 301b to make the wedge block 203c contact with the blocking block, so that the stop plate 202b can be raised and lowered, preventing the stop plate 202b from affecting the resetting of the airbag.

[0047] Example 3

[0048] Reference Figures 1 to 9 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides an anti-sway component 400 of the rotary wheel maintenance device using an air bag, which solves the problem of how to prevent the air bag lifting platform 103 from sliding as a whole when the worker tilts the operation after the position change. Its adsorption component 401 includes a plurality of mounting cylinders 401a arranged on the bottom plate 105, and a piston 401b is sealed and slidably connected in the mounting cylinder 401a, and a suction cup 401c is fixedly connected to the lower end of the piston 401b; the air pumping component 402 includes an air storage chamber 402a arranged in the bottom plate 105, the upper end of the mounting cylinder 401a is connected to the air storage chamber 402a, the outer end of the accommodating chamber 302a is connected to the bottom plate 105 through the exhaust pipe 402b, and the piston 401b is elastically connected to the inner wall of the air storage chamber 402a through the second spring 402c.

[0049] Specifically, the upper and lower parts of the mounting cylinder 401a are open, and a stop ring can be set on the inner wall of the upper end of the mounting cylinder 401a to prevent the piston 401b from detaching from the mounting cylinder 401a. The maintenance platform 102 here is flat so that the suction cup 401c can be adsorbed on the maintenance platform 102. The universal wheel 106 here is provided with a foot brake, which can also play a limiting role for the universal wheel 106. The exhaust pipe 402b in the left end accommodating chamber 302a passes through the lower end of the stop plate 202b and is connected to the exhaust pipe 402b in the right end accommodating chamber 302a.

[0050] During use, after the position of the airbag lifting platform 103 is adjusted and the first rotating shaft 301b is rotated to rotate so that the U-shaped frame 302b moves outward, the gas at the outer end of the accommodating chamber 302a can be pumped into the air storage chamber 402a through the exhaust pipe 402b. The air storage chamber 402a can be set to be smaller in size to ensure that the air pressure in the air storage chamber 402a is sufficient to push the piston 401b. When the gas enters the air storage chamber 402a, the air pressure in the air storage chamber 402a increases, thereby pushing the piston 401b to move downward, extending the second spring 402c, and allowing the suction cup 401c to be adsorbed on the ground, thereby increasing the overall stability and avoiding the sliding of the bottom plate 105. The second spring 402c here is elastic enough to ensure that the suction cup 401c can be pulled back.

[0051] In summary, by providing the anti-sway component 400, when the U-shaped frame 302b moves, the suction cup 401c can be made to stick to the maintenance platform 102 by pumping air, thereby preventing the bottom plate 105 from loosening and preventing the airbag lifting platform 103 from slipping when the worker tilts, thereby further ensuring the overall stability.
