Description

Technical Field

[0001] This invention relates to the field of dam operation equipment for hydropower projects, and in particular to a spring-loaded slot type modular platform connector. Background Technology

[0002] In slag removal operations at hydropower dams, intelligent slag removal machines need to be used in conjunction with spider cranes for lifting and movement to complete slag removal and dredging operations in various scenarios, including in front of, behind, and at the bottom of the dam. Current technologies primarily use traditional bolt-type or hook-type connections between spider cranes and slag removal platforms, which have several drawbacks: First, bolt-type connections are cumbersome to assemble and disassemble, and given the limited working space at the dam, this time-consuming and labor-intensive process reduces slag removal efficiency. Second, ordinary hook-type connections lack elastic limiting structures, making them prone to loosening and swaying during lifting operations, posing safety hazards, and unable to withstand the slight load impacts of crane lifting. Third, existing connectors are mostly fixed structures without steering capabilities; adjusting the working direction of the slag removal platform relies on the overall movement of the crane, making operation difficult and reducing flexibility for multi-directional slag removal operations at dams. Fourth, the slag removal environment at dams is humid, and intelligent slag removal machines use hydraulic power; existing connectors lack effective sealing and protection structures, making them susceptible to corrosion from moisture and hydraulic oil, causing internal component failures and affecting operational stability.

[0003] Therefore, a spring-loaded slot type modular platform connector is proposed to solve the above problems. Summary of the Invention

[0008] In a preferred embodiment of the present invention, the adjustable speed motor is bolted to the gearbox cover plate by the fastening bolts, and the power output end is sealed to the transmission gear assembly by the sealing packing to provide power to the transmission gear assembly.

[0009] In a preferred embodiment of the present invention, the counterweight is bolted to the side of the gearbox cover away from the adjustable speed motor by the fastening bolts to balance the load on the hook end of the slag removal platform.

[0010] In a preferred embodiment of the present invention, the spring stop block is provided with a groove structure at one end of the spring to fix the spring.

[0011] In a preferred embodiment of the present invention, an anti-detachment structure is provided at the end of the crane connecting rod near the spring stop.

[0012] In a preferred embodiment of the present invention, a stepped and grooved anti-leakage structure is provided at the connection between the gearbox housing and the gearbox cover plate, and a corresponding stepped and pin-type anti-leakage device is provided at the connection between the gearbox cover plate and the gearbox housing.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a spring-loaded slot 12 type modular platform connector includes: Spring slot assembly 1 The spring slot assembly 1, as a connecting component to the boom end of the spider crane, primarily addresses the shortcomings of traditional bolt-type connections (cumbersome assembly and disassembly) and ordinary hook-type connections (easily loosened and lacking cushioning). Its structure consists of a spring 15, a spring stop 16, a spring slot 12, a spring slot cover plate 13, a crane connecting rod 11, and spring slot cover plate fastening bolts 14. The specific assembly process is as follows: First, the spring 15 is embedded into the spring slot 12, with one end of the spring 15 abutting against the inner wall of the spring slot 12 and the other end abutting against the spring stop 16. The spring stop 16 has a grooved spring stop slot 161 near the end of the spring 15, into which the end of the spring 15 is engaged, thus achieving spring 15... The spring 15 is fixed in place to prevent it from shifting under stress. Then, one end of the crane connecting rod 11 is abutted against the end of the spring stop 16 away from the spring 15. The end of the crane connecting rod 11 that abuts against the spring stop 16 is provided with an anti-disengagement structure 111. The anti-disengagement structure 111 adopts an annular protrusion design, and its outer diameter is slightly larger than the inner diameter of the spring slot 12, which can effectively prevent the crane connecting rod 11 from slipping out of the spring slot 12 under stress. Finally, the spring slot cover plate 13 is connected to the spring slot 12 through the spring slot cover plate fastening bolt 14 to encapsulate the spring 15, the spring stop 16 and the crane connecting rod 11. At the same time, this detachable connection method also facilitates subsequent installation and maintenance. This component enables quick and flexible snap-fit ​​connection between the spider crane and the connector. Compared with traditional bolted connections, disassembly and assembly do not require special tools, which greatly improves the efficiency of equipment connection. In addition, the cooperative structure of spring 15 and spring stop 16 can buffer the load impact during hoisting operations and effectively prevent the connection from loosening, thus improving the safety of hoisting operations. After the spring slot assembly 1 is assembled, it is fixedly connected to the boom end of the spider crane through the crane connecting rod 11, providing upper support for the entire connector and adapting to the use requirements of limited working space in dams.

[0028] Transmission gear steering assembly 2 The gear shifting assembly 2 is used to enable flexible steering adjustment of the intelligent slag removal platform, solving the problems of existing connectors lacking steering function and being difficult to operate. Its structure consists of a gearbox housing 211, a gearbox cover plate 212, a gear shifting gear set, an intelligent slag removal platform hook 28, a bearing 26, a sealing gasket 210, a sealing packing 27, and cover plate fastening bolts 29. The specific structure and assembly are as follows: Both the gearbox housing 211 and the gearbox cover 212 are integral metal structures made of high-strength alloy steel, possessing excellent load-bearing capacity and corrosion resistance, suitable for the humid and hydraulically corroded working environment of hydropower stations. Addressing the issue of corrosion of components caused by the humid dam working environment and the hydraulic power of the intelligent slag remover, a stepped and grooved anti-leakage structure is provided at the connection between the gearbox housing 211 and the gearbox cover 212. Correspondingly, a matching stepped and pin-type anti-leakage structure is provided at the connection between the gearbox cover 212 and the gearbox housing 211. During assembly, the sealing gasket 210 is first installed at the connection point between the two parts. Then, the gearbox cover plate 212 is bolted to the upper end of the gearbox housing 211 using the cover plate fastening bolts 29. This forms a protective structure that covers the gear set and also serves as an integral load-bearing connecting component. Its upper end is movably connected to the spring slot assembly 1, and its lower end is sealed to the hook 28 of the intelligent slag removal platform. This effectively blocks moisture and hydraulic oil in the dam operation environment, preventing corrosion and failure of the internal gear set and adjustable speed motor 3, and improving the environmental adaptability and operational stability of the connecting component.

[0029] The transmission gear set is located inside the gearbox housing 211 and consists of a motor gear 21, a primary transmission gear 22, a secondary transmission gear 23, a tertiary transmission gear 24, and a steering gear 25. The assembly and connection relationships of each gear are as follows: The motor gear 21 is welded to the drive shaft of the adjustable speed motor 3 and connected to the adjustable speed motor 3 through a sealing packing 27 to achieve sealing at the power input end; the primary transmission gear 22 is movably mounted on the end of the intelligent slag removal platform hook 28 away from the hook via a bearing 26, and achieves autonomous rotation through the bearing 26. The primary transmission gear 22 meshes with the motor gear 21 for connecting... The adjustable speed motor 3 transmits power; the secondary gear 23 and the tertiary gear 24 are welded and fixed together to form an integrated structure. Both the upper and lower ends are connected to the gearbox housing 211 through bearings 26 to ensure the stability of the rotation process. The secondary gear 23 meshes with the primary gear 22, and the tertiary gear 24 meshes with the steering gear 25 to realize the step-by-step transmission of power. The steering gear 25 is welded and fixed on the hook 28 of the intelligent slag removal platform. The rotation of the steering gear 25 drives the hook 28 of the intelligent slag removal platform to turn synchronously, thereby realizing the steering adjustment of the intelligent slag removal platform. The adjustable speed motor 3, in conjunction with the variable speed gear set, can achieve heavy-load low-speed steering, and the speed can be adjusted via remote control system. It is suitable for the multi-directional operation requirements of the four-step integrated "collection, pushing, crushing and gathering" of dam slag removal, without relying on the overall movement of the crane to adjust the operation direction, thus reducing the difficulty of operation. The bearings 26 are set at each shaft of the variable speed gear assembly. Corrosion-resistant bearings 26 are selected to reduce the friction during the rotation of the shaft, improve the steering flexibility and the service life of the components. At the same time, in conjunction with the balance design of the counterweight 4, it can reduce the off-center wear of the steering shaft and further extend the service life of the components.

[0030] Assembly of adjustable speed motor 3, counterweight 4 and fastening bolts The adjustable speed motor 3 is fastened to the gearbox cover plate 212 by fastening bolts. Its power output end is sealed to the motor gear 21 of the gearbox assembly through the sealing packing 27, providing power to the gearbox assembly. The adjustable speed motor 3 can adjust the speed according to the operation requirements, thereby adjusting the steering speed of the intelligent slag removal platform, adapting to different operating conditions, and working with the gearbox assembly to achieve heavy-load low-speed steering, meeting the flexibility requirements of multi-directional slag removal operations at the dam.

[0031] The counterweight 4 is bolted to the gearbox cover plate 212 on the side away from the adjustable speed motor 3 by fastening bolts. Its weight is designed to be adapted to the load of the intelligent slag removal platform. It is used to balance the load on the hook end of the slag removal platform, prevent the connector from tilting or deforming due to uneven force on both ends, ensure the stability of the connection and the safety of operation, and at the same time reduce the wear of the steering shaft under uneven load, extend the service life of the components, and improve the operating stability of the connector.

[0032] In this embodiment, all fastening bolts used are corrosion-resistant and high-strength bolts, and 210 sealing gaskets are added to all bolt connection positions to further improve sealing performance and prevent water vapor and hydraulic oil corrosion from causing bolt rust and loosening. It is suitable for the humid and corrosive working environment of hydropower stations with high hydraulic oil content. At the same time, the overall structure adopts a high-strength structure, which can meet the heavy-load hoisting requirements of dam slag removal and has strong compatibility with 8-ton hybrid electric spider crane and intelligent slag removal platform.

[0033] Working principle of the connector: When this spring-slot type 12 modular platform connector is in operation, it is first fixedly connected to the end of the spider crane boom via the crane connecting rod 11 of the spring-slot assembly 1, and then fixedly connected to the intelligent slag removal platform via the intelligent slag removal platform hook 28, thus completing the installation and fixing of the entire connector. This connection method does not require special tools and is convenient to install and disassemble, solving the problems of cumbersome, time-consuming and labor-intensive disassembly and assembly of traditional bolted connections, and greatly improving the operating efficiency in the limited working space of the dam. The counterweight 4 plays a role at this time, balancing the load at the end of the intelligent slag removal platform hook 28, ensuring that the overall force of the connector is balanced, avoiding tilting, and reducing the off-center wear of the steering shaft, thus extending the service life of the components.

[0034] When the steering angle of the intelligent slag removal platform needs to be adjusted, the adjustable speed motor 3 is started. The adjustable speed motor 3 drives the motor gear 21 on its transmission shaft to rotate, and the motor gear 21 drives the meshing first-stage gear 22 to rotate. The first-stage gear 22 drives the meshing second-stage gear 23 to rotate. Since the second-stage gear 23 and the third-stage gear 24 are welded together, the third-stage gear 24 rotates synchronously. The third-stage gear 24 drives the meshing steering gear 25 to rotate, and the steering gear 25 drives the hook 28 of the intelligent slag removal platform, which is fixedly connected to it, to rotate, thereby realizing the steering adjustment of the intelligent slag removal platform. By adjusting the speed of the adjustable speed motor 3, the steering speed can be controlled to achieve heavy-load low-speed steering. The speed can also be adjusted through the remote control system, adapting to the multi-directional operation requirements of the four-step integrated "return, push, crush, and collect" slag removal at the dam. It does not require the overall movement of the crane to adjust the operation direction, reducing the difficulty of operation and improving the flexibility of operation.

[0035] During operation, the spring 15 in the spring slot assembly 1 can act as a buffer. When the intelligent slag removal platform is subjected to impact load, the spring 15 undergoes elastic deformation, absorbing part of the impact force and reducing damage to the spider crane boom and the connecting parts themselves. This solves the problems of ordinary hook-type connections having no elastic limit, being easy to loosen, and being unable to buffer load impact. The spring stop slot 161 on the spring stop block 16 can ensure that the spring 15 is firmly fixed and prevent the spring 15 from shifting. The anti-detachment structure 111 on the crane connecting rod 11 can prevent it from detaching from the spring slot 12, ensuring the reliability of the connection and improving the safety of the hoisting operation.

[0036] The anti-leakage structure, sealing gasket 210, and sealing packing 27 at the connection between the gearbox housing 211 and the gearbox cover plate 212 effectively block moisture and hydraulic oil in the dam operation environment, preventing corrosion and failure of the internal transmission gear set and adjustable speed motor 3. This adapts to the hydraulic power operation environment of the intelligent slag removal machine and improves the environmental adaptability and operational stability of the connecting parts. The setting of each bearing 26 reduces the friction during the rotation of the shaft, improves the steering flexibility and the service life of the components, ensures the stable realization of the steering function, and further guarantees the continuity of operation.

[0037] The connector in this embodiment specifically addresses four major defects of existing dam slag removal connectors. Combined with the beneficial effects of the invention, it possesses the following significant advantages: 1. The invention achieves rapid and elastic engagement between the spider crane and the connector through the spring-slot assembly 1. Compared to traditional bolt connections, disassembly and assembly require no special tools, significantly improving the efficiency of equipment connection. Furthermore, the cooperative structure of spring 15 and spring stop 16 can buffer the load impact during hoisting operations, effectively preventing loosening of the connection and improving the safety of hoisting operations, thus adapting to the limited operating space requirements of dams; 2. The design of the variable-speed gear steering assembly 2 enables flexible steering adjustment of the intelligent slag removal platform. The adjustable-speed motor 3, in conjunction with the variable-speed gear set, can achieve heavy-load low-speed steering, and the speed can be adjusted via remote control, adapting to the multi-directional operation requirements of the four-step integrated "return, push, crush, and collect" process for dam slag removal. It eliminates the need to rely on the overall movement of the crane to adjust the operating direction, reducing operational difficulty; 3. The integrated encasing structure of the outer shell 211, combined with oil-resistant and waterproof seals, effectively blocks moisture and hydraulic oil in the dam's operating environment, preventing corrosion and malfunctions of the internal transmission gear set and adjustable speed motor 3. It is suitable for the hydraulic power operation environment of the intelligent slag removal machine, improving the environmental adaptability and operational stability of the connecting parts. 4. The balanced design of the counterweight 4 reduces the off-center wear of the steering shaft, extending the service life of the components. At the same time, the bearing 26 reduces steering friction resistance, improving the smoothness of the slag removal platform's steering. 5. The overall modular design allows for the disassembly of the spring slot assembly 1 and the transmission gear steering assembly 2, enabling individual maintenance and replacement of components, reducing equipment maintenance costs and downtime. Furthermore, the connecting parts are of high strength, adaptable to the heavy-duty lifting requirements of dam slag removal, and highly compatible with the 8-ton hybrid electric spider crane and intelligent slag removal platform, improving the overall operational efficiency of the intelligent dam slag removal system.

[0038] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of these fall within the protection scope of the present invention.
