Description

Technical Field

[0001] The present invention belongs to the technical field of power maintenance, and particularly relates to a mobile power maintenance device with a lifting mechanism. Background Art

[0002] A power maintenance machine is a professional device designed for the maintenance and repair of power systems. It is mainly used for daily inspections, fault troubleshooting, and repair operations of power facilities such as substations and transmission lines. According to different functional requirements and technical characteristics, power maintenance machines can be divided into various types. The structural components include a chassis: serving as the basic platform of the entire device, usually equipped with wheels or tracks to ensure good mobility and stability. A lifting mechanism: This is one of the core components of this type of maintenance device, which realizes height adjustment in the vertical direction through a hydraulic cylinder or other forms of power sources, enabling workers to safely reach working positions at different heights. A work bucket / basket: Located at the top of the lifting mechanism, it is used to carry operators and their tools to ensure safety and comfort during high-altitude operations. A control system: including but not limited to components such as an electrical control cabinet and a remote controller, which is responsible for the operation management of the overall device, such as lifting control, speed adjustment, etc. The main features are high flexibility: having strong terrain adaptability and being able to move flexibly in complex environments; at the same time, the lifting mechanism can be quickly adjusted to an appropriate height according to actual needs. Strong safety: adopting multiple safety guarantee measures, such as limit switches, emergency stop buttons, etc., to ensure absolute safety during use. High efficiency and convenience: The integrated design reduces on-site preparation time and improves work efficiency; in addition, the remote control function also greatly facilitates operators. Wide application scope: It is not only applicable to the inspection and maintenance of conventional power facilities but also can handle emergency repair tasks in emergencies. The main applications are internal inspection of substations: regularly conducting comprehensive inspections on in-station equipment to timely discover potential hidden dangers. Detection and repair on transmission lines: dealing with line damage caused by reasons such as bad weather. Support for outdoor temporary construction: providing a necessary high-altitude operation platform for new construction or renovation projects.

[0003] Currently, the lifting mechanism of existing power maintenance machines realizes lifting or lowering through a transmission shaft pair, and the force is transmitted between multiple shafts, resulting in poor practical effects. Therefore, a new type of mobile power maintenance device with a lifting mechanism that does not use a motor and a transmission shaft structure is needed. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a mobile power maintenance device with a lifting mechanism, solving the problems in the above background art.

[0005] The object of the present invention is achieved as follows: A mobile power maintenance device with a lifting mechanism, which includes a box body. The box body has a structure without a top cover. A moving component is provided at the lower end of the box body. A hand pull handle is provided on the right side wall of the box body. A lifting component is provided inside the box body. The lifting component includes a bottom plate fixedly arranged at the inner bottom of the box body. A front vertical plate and a rear vertical plate are vertically and fixedly connected to the upper surface of the bottom plate. A connection end is fixedly arranged on the upper surface of the bottom plate. The connection end is connected to a horizontal hydraulic cylinder with a telescopic rod extending horizontally. A front guide hole is opened on the side wall of the front vertical plate, and a rear guide hole is opened on the side wall of the rear vertical plate. A front connecting piece is slidably connected inside the front guide hole, and a rear connecting piece is slidably connected inside the rear guide hole. A bearing plate is provided at the upper ends of the front connecting piece and the rear connecting piece. And the front connecting piece and the rear connecting piece are connected to the telescopic rod of the hydraulic cylinder through a transmission component. By setting the hydraulic cylinder and the lifting component and removing the original motor and transmission shaft structure, the main advantages of using hydraulic lifting are greater lifting force and higher load-bearing capacity. The hydraulic system can provide greater pressure and more stable output. Therefore, greater lifting force and higher load-bearing capacity can be achieved, which is very important for applications that need to handle heavy objects or adjust the height within a large range.

[0006] Further, the transmission component includes a connection ring connected to the telescopic rod of the hydraulic cylinder. A horizontal shaft is arranged inside the ring body of the connection ring. The front end of the horizontal shaft penetrates through the front guide hole, and the horizontal shaft is slidably matched with the front guide hole. The rear end of the horizontal shaft penetrates through the rear guide hole, and the horizontal shaft is slidably matched with the rear guide hole. A front side plate is fixedly connected to the front end of the horizontal shaft, and a rear side plate is fixedly connected to the rear end of the horizontal shaft. A front lower left tooth handle is fixedly connected to the left end of the front side plate, and a front upper right tooth handle is fixedly connected to the right end of the front side plate.

When in use, the flexible height adjustment can accurately control the lifting speed and the final height according to actual needs, without relying on a fixed gear ratio or pitch like a transmission shaft. This flexibility is very useful for high-altitude operations in complex environments.

[0008] Further, the front auxiliary component includes a front middle plate. The left end of the front middle plate is provided with a front upper left shaft and a front lower left shaft, and the right end of the front middle plate is provided with a front upper right shaft and a front lower right shaft; the upper end of the front left second rod is rotatably connected to the front lower left shaft, and the upper end of the front right second rod is rotatably connected to the front lower right shaft; the front upper left shaft is rotatably connected with a front left third rod, the outer end of the front left third rod is rotatably connected with a front left fourth rod, the front upper right shaft is rotatably connected with a front right third rod, and the outer end of the front right third rod is rotatably connected with a front right fourth rod.
