[0023] 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.

[0024] 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.

[0025] 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 an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0026] Example 1

[0027] Reference Figure 1 , which is the first embodiment of the present invention, provides a load-carrying lifting device designed for the load-carrying hole of a hydropower unit, including a load-carrying platform 100, a spider crane 200 and a load-carrying hole channel 300.

[0028] Specifically, the spider crane 200 is fixedly arranged above the supporting platform 100 to facilitate lifting and transferring the maintenance materials of the hydropower unit. The lifting hole channel 300 is a channel arranged between the supporting platform 100 and the spider crane 200. When the spider crane 200 is working, the material is lifted from the supporting platform 100 and passed through the lifting hole channel 300 to complete the operation.

[0029] The spider crane 200 includes a crawler disc 201, a support arm 202 fixedly mounted on the crawler disc, and a main boom 203. At least four support arms 202 are provided to ensure safety and stability. The crawler disc 201 is fixedly mounted at the bottom of the spider crane 200 as a walking component. When driven by the motor, the crawler disc 201 starts to start and continuously drives the crawler disc 201 to rotate on the ground to move the spider crane 200 forward. The support arms 202 are fixedly mounted on both sides of the crawler disc 201 and two are fixedly mounted on each side. When the crawler disc 201 moves forward, the four support arms 202 are responsible for enhancing the stability of the spider crane. The main boom 203 is fixedly mounted at one end of the spider crane 200. The main boom 203 also includes a connecting rope and a hook.

[0030] During use, when the spider crane 200 moves forward to the hanging hole channel 300, the main boom 203 adjusts the direction and angle, aligns the connecting rope and the hook with the hanging hole channel 300, and then releases the connecting rope until the hook contacts the material to be transferred. After the arrangement is completed, the material placed on the supporting platform 100 is lifted through the hanging hole channel 300 to the target position.

[0031] In summary, through the coordinated use of the carrying platform 100, the spider crane 200 and the lifting hole channel 300, materials that are inconvenient to transfer can be safely lifted and transported, thereby reducing safety risks and saving manpower.

[0032] Example 2

[0033] Reference Figure 3 and Figure 4 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0034] Specifically, the bearing platform 100 includes a telescopic top-pressing support mechanism 102, which is fixedly arranged at the lower part of the bearing platform 100 and close to one end of the hanging hole channel 300. The telescopic top-pressing support mechanism 102 is tightly fitted with one side of the inner wall of the hanging hole channel 300. The telescopic top-pressing support mechanism 102 includes a fixed installation component 102a, a sliding component 102b, and a driving component 102c. The fixed installation component 102a is fixedly arranged on one side of the bearing platform 100, the sliding component 102b is fixedly arranged on one side of the fixed installation component 102a, and the driving component 102c is fixedly arranged on one side of the sliding component 102b. The fixed installation component 102a is fixedly arranged on the long side of the bearing platform 100 to ensure the stability and reliability of the entire mechanism during operation. The driving component 102c drives the sliding component 102b to move toward the inner wall of the hanging hole channel 300 until it is against and fits, making the entire bearing platform 100 more stable.

[0035] The sliding assembly 102b includes a sliding track 102b-1, a sliding connection block 102b-2, an adapter plate 102b-3, and a top pressure plate 102b-4. The sliding track 102b-1 is bolted to the fixed installation assembly 102a and the sliding connection block 102b-2 respectively, the adapter plate 102b-3 is bolted to one end of the sliding connection block 102b-2, and the top pressure plate 102b-4 is bolted to one side of the adapter plate 102b-3. The top pressure plate 102b-4 is the main working part of the telescopic top pressure support mechanism 102, and its surface is specially treated to ensure good contact with the object being pressed. The sliding track 102b-1 is stably fixed by bolt connection. When the sliding assembly 102b is driven by thrust, one end of the sliding connection block 102b-2 will move on the sliding track 102b-1 until the top pressure plate 102b-4 fits on the inner wall of the hanging hole channel 300.

[0036] The driving assembly 102c includes a front hinge seat 102c-1, a power cylinder 102c-2, a rear hinge seat 102c-3, a telescopic pressing mechanism pin shaft 102c-4, and a telescopic pressing mechanism fixing pin 102c-5. The front end of the power cylinder 102c-2 is rotatably connected to the front hinge seat 102c-1 through the telescopic pressing mechanism pin shaft 102c-4 and the telescopic pressing mechanism fixing pin 102c-5. The rear end of the power cylinder 102c-2 is rotatably connected to the rear hinge seat 102c-3 through the telescopic pressing mechanism pin shaft 102c-4 and the telescopic pressing mechanism fixing pin 102c-5. The front hinge seat 102c-1 is bolted to the sliding connection block 102b-2, and the rear hinge seat 102c-3 is bolted to the fixed installation assembly 102a. The power cylinder 102c-2 serves as a driving device to provide a strong power for the sliding assembly 102b to realize the pressing operation on the wall. The front hinge seat 102c-1 and the rear hinge seat 102c-3 are two hinge points of the driving assembly 102c, so that the driving assembly 102c can achieve flexible movement. The pin shaft and the pin are fasteners connecting various components, which play a role of fixing and connecting, ensuring the structural integrity and stability of the entire telescopic pressing mechanism.

[0037] When in use, the power cylinder 102c-2 provides power to drive the sliding connection block 102b-2 to slide smoothly on the sliding track 102b-1, so that the sliding assembly 102b can be extended and retracted along the sliding track 102b-1. When the sliding connection block 102b-2 extends toward the inner wall of the hanging hole channel 300, the top pressure plate 102b-4 will contact and squeeze the inner wall of the hanging hole channel 300 until it is completely fitted and fixed to the inner wall, thereby effectively achieving stable support and fixation of the load-bearing platform 100.

[0038] Example 3

[0039] Refer to 2~ Figure 6 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0040] Specifically, the carrying platform 100 further includes a platform carrying mechanism 101 , a telescopic fixing mechanism 103 and a flip carrying mechanism 104 . The telescopic fixing mechanism 103 is fixedly arranged on one side of the platform carrying mechanism 101 , and the flip carrying mechanism is fixedly arranged on both ends of the platform carrying mechanism 101 .

[0041] Furthermore, the platform bearing mechanism 101 includes a platform 101a and a reinforcing beam 101b, and the two ends of the reinforcing beam 101b are respectively fixedly connected to the bottom of the platform 101a and the inner wall of the hanging hole channel 300. The reinforcing beam 101b is welded obliquely to the bottom of the platform 101a, which increases the stability of the platform 101a and improves the bearing capacity of the overall structure.

[0042] The telescopic fixing mechanism 103 includes a wall fixing block 103a and a telescopic rod 103b, the wall fixing block 103a is bolted to the telescopic rod 103b, and the telescopic rod 103b is slidably matched with one end of the platform 101a. The telescopic rod 103b can slide in one end of the platform 101a to flexibly adjust the position to ensure that the spider crane 200 can accurately lift materials when working. The wall fixing block 103a is fixedly arranged at both ends of the telescopic rod 103b. When the telescopic rod 103b is extended to the wall and fits tightly, the wall fixing block 103a and the wall are fixed by bolts to ensure the stability and reliability of the structure.

[0043] The flip bearing mechanism 104 includes a front flip mechanism 104a, a rear flip mechanism 104b and a flip mechanism 104c after passing the tube. The front flip mechanism 104a, the rear flip mechanism 104b and the flip mechanism 104c after passing the tube are all connected to the flip fixing pin 104e by rotation through the flip pin 104d to flip. The flip bearing mechanism 104 is fixed to the platform bearing structure through the stable connection of the pin and the pin, and has the function of rotating within a certain angle range. It can effectively fill the space on both sides of the bearing platform 100 and the hanging hole channel 300 to improve the stability and safety of the overall structure. When the telescopic top pressure support mechanism 102 and the telescopic fixing mechanism 103 are connected, the front flip mechanism 104a, the rear flip mechanism 104b and the flip mechanism 104c after passing the tube will rotate until they are completely flattened.

[0044] A docking track 101a - 1 is disposed on one end surface of the platform 101a for connecting to other transport mechanisms, and other transport mechanisms can directly transport materials to the carrying platform 100 via the docking track 101a - 1 .

[0045] When in use, the telescopic top pressure support mechanism 102 and the telescopic fixing mechanism 103 are first connected to the inner wall of the hanging hole channel 300, and the flip bearing mechanism 104 fully unfolds the platform 101a. The material has been transferred from the docking track 101a-1 to the platform 101a. The spider crane 200 will lift the material from the platform 101a through precise operation and then lift it out from the hanging hole channel 300, thereby realizing the efficient transfer operation of the maintenance material from bottom to top or from top to bottom.

[0046] In summary, the beneficial effects of the present invention are:

[0047] 1. The present invention has a rigorous design and a stable structure. During the maintenance operation, if parts or tools need to be transferred from each maintenance layer to the generator layer, the carrying platform 100 can be quickly built and work with the spider crane 200 to achieve efficient and safe transfer of materials. This effectively reduces the direct participation of operators, thereby reducing the occupancy rate of lifting equipment resources during the maintenance process.

[0048] 2. The device adopts a modular design, aiming to realize the convenient disassembly and folding function of the device, thereby significantly reducing the storage space occupied. This design is not only convenient for operation during transportation, but also greatly facilitates the assembly process of the device, showing the characteristics of efficient and flexible use.

[0049] 3. The device of the present invention has a wide range of applicability. Its design ingeniously combines the telescopic top pressure support mechanism 102 and the telescopic fixing mechanism 103, and can flexibly adapt to different sizes of hanging holes, thereby effectively meeting the maintenance needs of various types of units.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
