Description

Technical Field

[0001] This utility model relates to the field of hydropower station maintenance, and in particular to a maintenance platform and a flow channel maintenance and transfer device. Background Technology

[0002] Currently, maintenance work on the intake channel of hydropower stations mainly employs two methods: one is the traditional method of descending along the portal ladder in conjunction with a self-climbing device, and the other is a semi-mechanized method using an integrated support system. However, both methods have significant technical defects and safety risks. The traditional method requires workers to repeatedly disassemble and inspect tools at dangerous heights near edges, posing a risk of fall. Furthermore, the limited space on the intermediate platform leads to low efficiency in transporting maintenance materials, severely impacting the overall work progress. While existing integrated support systems have improved material storage and safety conditions to some extent, they still reveal numerous problems in practical application, including a lack of stable support for workers during descent, interruptions in on-site communication signals, inability to accurately deliver materials to the channel floor, and the inability to effectively inspect vents due to work path limitations. These problems not only increase the operational risks for workers but also restrict the overall efficiency of the maintenance work. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is that the current maintenance of the water intake of hydropower stations faces problems such as high risks of high-altitude operations, difficulty in material transportation, and limited equipment functions.

[0004] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes a maintenance platform, which includes,

[0005] Hanging basket;

[0006] A hoist is installed on both sides of the suspended platform. A main rope is installed inside the hoist, one end of which is fixed to a designated installation point. The hoist's operation allows the suspended platform to be adjusted along the main rope. Once one end of the main rope is fixed, activating the hoist causes it to slide the suspended platform along the main rope, thus adjusting its height. Maintenance personnel and necessary equipment can be located inside the suspended platform. This device not only facilitates operation by maintenance personnel but also allows for equipment transfer while reducing the operational risks for maintenance personnel.

[0007] In a preferred embodiment of the maintenance platform of this utility model, a winding assembly is further included. The winding assembly includes a drive source disposed at the bottom of the basket and a winding roller adapted and connected to the drive source. By starting the drive source at the same time as starting the hoist, when the hoist moves downward, the drive source will drive the winding roller to rotate forward to release the wire; if the hoist moves upward, the drive source will drive the winding roller to rotate in reverse to retract the wire, thereby ensuring effective wire storage and avoiding messy stacking.

[0008] In a preferred embodiment of the maintenance platform of this utility model, a support assembly is further included. The support assembly includes a bottom motor installed at the bottom of the suspended basket, a first connecting frame fixedly connected to the bottom of the suspended basket, and a bidirectional lead screw rotatably connected to the first connecting frame.

[0026] Reference Figures 1-3This embodiment provides a maintenance platform, which includes,

[0027] Hanging basket 1;

[0028] Hoist 2 is installed on both sides of the suspended platform 1. A main rope 21 is installed inside hoist 2, with one end of the main rope 21 fixed at a designated installation point. The suspended platform 1 is adjusted along the main rope 21 by the operation of hoist 2. After one end of the main rope 21 is fixed, starting hoist 2 causes it to slide along the main rope 21, thereby adjusting its height. Maintenance personnel and necessary maintenance equipment can be located inside the suspended platform 1. This equipment not only facilitates operation by maintenance personnel but also allows for the transfer of equipment while reducing the operational risks for maintenance personnel.

[0029] The suspended platform 1 is equipped with a safety rope 11 inside and a safety lock 12 at the top of the suspended platform 1. The safety rope 11 and the safety lock 12 are designed to work together. One end of the safety rope 11 is fixedly connected to a designated installation point, and the other end is wound around the winding roller 32. The other end of the main rope 21 is wound around the winding roller 32. With the cooperation of the safety rope 11 and the safety lock 12, emergency braking can be performed in the event of a rapid descent of the suspended platform 1 to ensure the overall safety of the equipment.

[0030] The suspended platform 1 is fixedly connected to the four sides of the railing 13, and the railing 13 is equipped with wall-mounted wheels 14 around its perimeter. The four corners of the bottom of the suspended platform 1 are equipped with bottom wheels 15. The design of the railing 13 provides safety protection for maintenance personnel. At the same time, the design of the wall-mounted wheels 14 ensures that even if the suspended platform 1 shakes during descent, it will not rub or collide with the flow channel wall. This protects the inner wall of the flow channel and reduces friction between the two, ensuring the stable adjustment of the suspended platform 1.

[0031] As one embodiment provided, such as Figures 1-4 It also includes a winding assembly 3, which includes a drive source 31 located at the bottom of the basket 1 and a winding roller 32 adapted to and connected to the drive source 31. By starting the drive source 31 at the same time as starting the hoist 2, when the hoist 2 moves downward, the drive source 31 will drive the winding roller 32 to rotate forward to release the wire; if the hoist 2 moves upward, the drive source 31 will drive the winding roller 32 to rotate in reverse to retract the wire, thereby ensuring effective storage of the wire and avoiding messy stacking.

[0032] The drive source 31 includes a base 311 fixedly connected to the bottom of the inside of the basket 1, a drive motor 312 set at the top of the base 311, and a protective shell 313 sleeved on the outside of the drive motor 312; by starting the motor 312, the rotating shaft 321 can be driven to achieve forward and reverse rotation.

[0033] The take-up roller 32 includes a rotating shaft 321 fixedly connected to the output shaft of the drive motor 312, a main wire reel 322 and an auxiliary wire reel 323 fixedly connected to the outside of the rotating shaft 321; the main rope 21 is wound around the main wire reel 322, the safety rope 11 is wound around the auxiliary wire reel 323, and the rotating shaft 321 can rotate in both directions under the operation of the motor 312.

[0034] As one embodiment provided, such as Figure 5 , Figure 6 It also includes a support assembly 4, which includes a bottom motor 41 installed at the bottom of the suspended basket 1, a first connecting frame 42 fixedly connected to the bottom of the suspended basket 1, and a bidirectional lead screw 43 rotatably connected to the first connecting frame 42. The outer side of the bidirectional lead screw 43 is provided with a first threaded block 44 and a second threaded block 45. Support legs 46 are provided on both sides of the first threaded block 44 and the second threaded block 45. The end of the bidirectional lead screw 43 away from the first connecting frame 42 is fixedly connected to the output end of the bottom motor 41.

[0035] The support leg 46 includes a second connecting block 461 fixedly connected to the bottom end of the suspended platform 1, a slide rod 462 slidably connected to the second connecting block 461, and a support plate 463 fixedly connected to one end of the slide rod 462. A first hinge rod 464 and a second hinge rod 465 are hinged to the end of the slide rod 462 away from the support plate 463. The other end of the first hinge rod 464 is hinged to a first threaded block 44, and the other end of the second hinge rod 465 is hinged to a second threaded block 45. By starting the bottom motor 41, the bidirectional lead screw 43 will rotate, thereby causing the first threaded block 44 and the second threaded block 45 to rotate along the bidirectional lead screw. 43. By sliding in opposite or relative directions through the first threaded block 44 and the second threaded block 45, the first hinge rod 464 and the second hinge rod 465 will pull or push the slide rod 462 to slide along the second connecting block 461, thereby adjusting the position of the support plate 463. When the basket 1 is being raised or lowered, the support plate 463 is in a retracted state to ensure the stable adjustment of the basket 1. When the basket 1 is in a designated position, the support plate 463 is in an extended state and is in close contact with the inner wall of the flow channel, thereby ensuring the stability of the basket 1 and ensuring the overall operational safety of the maintenance personnel.

[0036] In summary, the lifting and lowering adjustment of the suspended basket 1 is achieved through the main rope 21 in the hoist 2. One end of the main rope 21 is fixed to the installation point, and the other end is wound around the main line reel 322 of the take-up roller 32. At the same time, one end of the safety rope 11 is fixed to the installation point, and the other end is wound around the auxiliary line reel 323, which, together with the safety lock 12 at the top of the suspended basket 1, forms an emergency braking protection. The drive motor 312 of the drive source 31 synchronously controls the forward and reverse rotation of the take-up roller 32 through the rotating shaft 321. When the suspended basket 1 rises, it reverses to take in the line, and when it descends, it rotates forward to release the line, avoiding cable tangling. The bottom motor 41 of the support assembly 4 drives the bidirectional lead screw 43 to rotate, causing the first threaded block 44 and the second threaded block 45 to move relative to or in opposite directions. Through the first hinge rod 464 and the second hinge rod 465, the slide rod 462 is pushed to extend and retract, causing the support plate 463 to unfold or retract. It retracts during lifting to reduce friction, and unfolds during operation to fit against the flow channel wall to enhance stability. The guardrail 13 and wall-mounted wheels 14 further protect maintenance personnel and reduce the risk of collision between the suspended platform 1 and the flow channel wall. This design enables highly flexible height adjustment, automatic cable retraction, emergency braking, and operational stability, significantly improving safety and operational efficiency.

[0037] As one embodiment provided, such as Figure 1 , Figure 2 A flow channel inspection and transfer device includes an inspection platform and a gantry frame 5. The gantry frame 5 includes a rope hanger 51 fixedly connected to the top of the gantry frame 5, a caster wheel 52 fixedly connected to the bottom of the rope hanger 51, and support feet 53 set on the inner side of the gantry frame 5. The design of the rope hanger 51 allows for the stable installation of the main rope 21 and the safety rope 11, while the design of the caster wheel 52 allows for the overall movement of the equipment, providing convenience for the equipment.

[0038] The support foot 53 includes a threaded rod 531 threadedly connected to the gantry frame 5, a base block 532 fixedly connected to the bottom end of the threaded rod 531, and a handwheel 533 fixedly connected to the top end of the threaded rod 531. By rotating the handwheel 533, the threaded rod 531 will rise or fall along the inside of the gantry frame 5, thereby adjusting the position of the base block 532. When it is necessary to move the entire equipment, the base block 532 is adjusted so that it does not contact the ground, thus facilitating the adjustment of the equipment. After adjusting to the designated position, the base block 532 is adjusted to contact the ground to ensure the overall stability of the equipment.

[0039] In summary, the main rope 21 and safety rope 11 are secured by the rope hanger 51 at the top of the gantry 5, and the height of the base block 532 is adjusted by the handwheel 533 via the threaded rod 531 of the support foot 53: when moving, the base block 532 is suspended in the air, and the casters 52 facilitate overall movement; after positioning, the base block 532 contacts the ground to stabilize the gantry 5. Combined with the lifting and supporting functions of the suspended basket 1 of the maintenance platform, rapid movement and precise positioning of the equipment are achieved. At the same time, the synergistic effect of the gantry 5 and the suspended basket 1 ensures convenient transportation during maintenance and the overall structure's anti-overturning ability.

[0040] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways, as long as they do not depart from the scope of this utility model.
