Description

Technical Field

[0001] This invention relates to the field of tension machine technology. Specifically, it relates to a modular combined tension actuator and a modular combined electric tension machine. Background Technology

[0002] Tensioners are special overhead power and communication line installation equipment used to control cable tension during installation, ensuring accuracy and safety. They are classified into mechanical, hydraulic, fluid-driven, and electric types based on their transmission methods. Mechanical and hydraulic tensioners are mature products, while fluid-driven tensioners are also common abroad. For ease of relocation and transportation, tensioners are often designed with a trailer-mounted structure (e.g., ...). Figure 1 It mainly consists of a frame, front tension wheel assembly, rear tension wheel assembly, engine power source, control box, and hydraulic transmission (or mechanical transmission). Currently, hydraulic transmission is the most common in engineering applications, while mechanical and hydraulic transmission are relatively rare. Electric tension machines are still relatively rare in the domestic and international markets.

[0003] Tensioners operate in complex environments, often in field operations, frequently encountering high-altitude mountains, hilly areas, and swampy regions. Especially in high-altitude mountainous areas, fault depressions, basins, stepped terrain, alternating high mountains and deep valleys, crisscrossing rivers, and numerous lakes pose significant challenges to equipment transportation. Transportation becomes difficult even in these challenging environments, sometimes requiring the use of cableways to transport equipment to the mountains. However, cableways have weight limits for single trips, generally requiring a minimum of 4 tons. Because the final stage drive of the tension wheel uses gear transmission, very high requirements are placed on parallelism, coaxiality, positional accuracy, and center distance. Traditional disassembly and assembly methods are extremely difficult. Two-line tensioners also require parallel operation, necessitating the installation of two sets of tension wheels on the same shaft with high concentricity requirements. Therefore, a separate design for each wheel would be very challenging. By adopting a modular design for multi-line tensioners, the design can meet the requirement that each component weigh no more than 4 tons, while ensuring convenient and quick on-site assembly and fulfilling the equipment's operational requirements after installation. However, the mountainous terrain lacks sufficient tools and equipment, and poor assembly conditions prevent proper assembly. Therefore, developing a modular, combined two-line tensioning machine is an urgent technical problem that needs to be solved. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to provide a modular combined electric tension machine, which can effectively solve the problems of large size and heavy weight of two-line tension machines, overloading when using cableway transportation, and difficulty in reassembling on the mountain after disassembly.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: The modular combined tension actuator includes a wheel assembly module, a frame module, and a guide roller module. The wheel assembly module, frame module, and guide roller module are detachably connected to each other. The wheel assembly module has guide and limiting structures at both ends corresponding to the frame module. The frame module has a horizontal adjustment structure. The guide roller module is equipped with a detachable cleaning device.

[0006] Preferably, the wheel assembly module includes a rear wheel assembly module and a front wheel assembly module. Both ends of the rear wheel assembly module and the front wheel assembly module are provided with sliders. The frame module corresponding to the sliders is provided with dovetail grooves. The rear wheel assembly module and the front wheel assembly module are positioned with respect to the frame module through the sliders and the dovetail grooves. After the rear wheel assembly module and the front wheel assembly module are positioned, they are fixed together with bolts.

[0007] Preferably, there are two cleaning devices, located in front of the rope inlet end of the guide roller on the guide roller module. Each cleaning device includes a cylindrical cleaning box and brush bristles inside the cleaning box. A connecting rod is mounted outside the cleaning box and is bolted to the mounting shaft of the guide roller module.

[0008] Preferably, a level is installed on the middle beam of the frame module, and foot cups are installed at the bottom of the four corners of the frame module.

[0009] Preferably, the guide roller module is bolted to the frame module, and the guide roller module is located above the rear wheel assembly module.

[0010] The modular combined electric tension machine includes a generator set module, an electrical control cabinet module, an energy storage battery module, a hydraulic pump station module, a hydraulic wire-laying frame, and any one of the above modular combined tension actuators. The generator set module is connected to the energy storage battery module, the energy storage battery module is connected to both the electrical control cabinet module and the hydraulic pump station module, the electrical control cabinet module is connected to both the hydraulic pump station module and the motor reducer assembly on the tension actuator, and the hydraulic pump station module is connected to the hydraulic wire-laying frame.

[0011] The technical solution of the present invention achieves the following beneficial technical effects: 1. Compared with traditional mechanical, hydraulic and fluid transmission tension machines, the modular combined electric tension machine provided by this invention adopts an electric transmission method, which greatly simplifies the structure of the mechanical parts. It has the advantages of small size, light weight, easy centralized control, simple operation and convenient maintenance. In terms of energy transmission, electric wires replace hydraulic pipelines, which facilitates the on-site layout. The parts can be disassembled and connected, which facilitates transportation. 2. The modular combined tension actuator provided by this invention has a combined structural design, which can be disassembled into several modules. The dovetail groove structure design is used as a guide to ensure the accuracy and size of the rapid on-site assembly, which greatly facilitates on-site construction. On-site assembly is simple and time-saving, which facilitates cableway transportation and on-site assembly, and solves the problems of use and transportation in plateau mountainous areas. 3. The present invention installs a horizontal adjustment mechanism on the tension execution module, which facilitates the alignment and installation of the wheel set by leveling the frame. In addition, a detachable cleaning device is added in front of the guide roller module, which is easy to install and can clean impurities on the wire, making it easier to wind.

Detailed Implementation

[0015] like Figure 2 , 3 As shown, the modular tension actuator includes a wheel assembly module, a frame module, and a guide roller module. The wheel assembly module, frame module 2, and guide roller module 5 are all detachably connected to each other. The wheel assembly module has guide and limiting structures at both ends corresponding to the frame module 2. The frame module 2 has a horizontal adjustment structure and is composed of a motor, a reducer, and a steel frame. The motor and reducer are collectively referred to as the motor-reducer assembly 4, which is symmetrically arranged with its sides staggered vertically. The guide roller module 5 is equipped with a detachable cleaning device.

[0016] The wheel assembly module includes a rear wheel assembly module 1 and a front wheel assembly module 3. The front wheel assembly module 3 and the rear wheel assembly module 1 each consist of an inner wheel and an outer wheel connected in series on the same main shaft, ensuring coaxiality of the two wheels and facilitating synchronization of the inner and outer wheels via mechanical connection during wheel alignment. Both ends of the rear wheel assembly module 1 and the front wheel assembly module 3 have sliders on their main shaft boxes. Corresponding to the sliders, the frame module 2 has dovetail grooves 21. The sliders and dovetail grooves 21 are used to position the rear wheel assembly module 1 and the front wheel assembly module 3 relative to the frame module 2. After positioning, the rear wheel assembly module 1 and the front wheel assembly module 3 are fixed together with bolts. During installation, a crane is used to hoist the rear wheel assembly module 1 and the front wheel assembly module 3 onto the end beams of the frame module 2, with the dovetail grooves 21 at both ends of the wheel assembly serving as guides. The rear wheel assembly module 1 is then connected to the frame module 2 with bolts, and the preload of the bolts secures the front wheel assembly module 3 and the rear wheel assembly module 1 to the frame module 2. The dovetail groove 21 serves as a guide to ensure that the wheelset can be limited to the left and right, and to ensure that the position meets the requirements.

[0017] Two cleaning devices are provided, located in front of the rope inlet end of the guide roller on the guide roller module 5, such as... Figure 4 As shown, the cleaning device includes a cylindrical cleaning box 8 and brush bristles 82 installed inside the cleaning box 8. A connecting rod 83 is installed outside the cleaning box 8. The connecting rod 83 is bolted to the mounting shaft 51 of the guide roller module 5. The cleaning device can clean impurities on the wires and facilitate winding.

[0018] A level 6 is installed on the middle beam of the frame module 2, and feet 7 are installed at the bottom of the four corners of the frame module 2. During on-site assembly, the level 6 can be observed to confirm whether the frame module 2 is level. If it is not level, it may affect the installation of the wheel assembly module. Therefore, the level of the frame module 2 is adjusted by the four feet 7 to facilitate the subsequent installation of the wheel assembly module.

[0019] The guide roller module 5 is bolted to the frame module 2, and is located above the rear wheel assembly module 1. The guide roller module 5 ensures that the wire entering the tension wheel groove from the feed reel is in a straight line with the first groove, preventing the wire from falling into or misaligning the groove. The guide roller module 5 is bolted to the frame module 2, allowing for easy disassembly. It is typically installed after the wheel assembly module is installed, and then the cleaning device is installed on the guide roller module 5.

[0020] like Figure 5As shown, the modular combined electric tension machine is characterized by comprising a generator module 9, an electrical control cabinet module 11, an energy storage battery module 10, a hydraulic pump station module 12, a hydraulic wire-laying frame 13, and a modular combined tension actuator 14 according to any one of claims 1-5. The generator module 9 is connected to the energy storage battery module 10, which is connected to both the electrical control cabinet module 11 and the hydraulic pump station module 12. The electrical control cabinet module 11 is connected to both the hydraulic pump station module 12 and the motor reducer assembly 4 on the tension actuator 14. The hydraulic pump station module 12 is connected to the hydraulic wire-laying frame 13. During traction operation, the tension actuator transmits power from the motor to the final stage transmission pinion via the reducer. The pinion drives two large gear rings to rotate in the same direction, which in turn drives the tension wheel to rotate and pull the conductor. During tensioning and wire-laying, the conductor pulls the tension wheel to rotate, and the tension wheel drives the final stage gear, reducer, and motor to rotate in the opposite direction. The control unit can provide resistance to the reducer, thereby controlling the tension and the wire-laying speed.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
