Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic power, in particular to a self-adjusting hydraulic power unit. Background Art

[0002] The self-adjusting hydraulic power unit is a highly advanced mechanical system that uses precision hydraulic control technology to automatically adjust the power output to suit different workloads and environmental conditions. The emergence of this technology stems from the continuous pursuit of improving the efficiency and reliability of mechanical systems.

[0003] In hydraulic systems, traditional control methods often rely on preset fixed parameters, which may not be able to fully adapt to various changes that may occur in the actual working process. For example, in the case of sudden load changes, temperature changes or oil contamination, traditional hydraulic systems may not be able to maintain optimal working performance and may even cause system failures. The original intention of the design of the self-adjusting hydraulic power unit is to solve these problems. It integrates sensors, actuators and control algorithms to achieve real-time monitoring and automatic adjustment of the dynamic performance of the hydraulic system.

[0004] The background of self-adjusting hydraulic power unit can be traced back to the mid-20th century. With the development of industrial automation and precision manufacturing, higher efficiency and reliability requirements have been put forward for mechanical systems, especially in the fields of aerospace, automobile manufacturing, heavy machinery, etc. The performance requirements for hydraulic systems are extremely stringent. The application of traditional hydraulic systems in these fields often faces problems such as slow response speed and low adjustment accuracy. Therefore, the development of a self-adjusting hydraulic power unit that can automatically adapt to various working conditions and maintain stable and efficient operation of the system became a hot topic of research at that time.

[0005] The core technology of the self-adjusting hydraulic power unit lies in the fact that its integrated sensors and actuators can monitor the status of the hydraulic system in real time, such as key parameters such as pressure, flow, and temperature, and feed this information back to the control unit. The control unit analyzes and processes this information through a built-in algorithm, and issues corresponding adjustment instructions to control the actuator to adjust the opening of the hydraulic valve, the output of the pump, etc., so as to achieve rapid response and precise adjustment to changes in external loads. This technology not only improves the response speed and adjustment accuracy of the hydraulic system, but also enhances the stability and reliability of the system.

[0006] With the development of materials science, electronic technology and control theory, the technology of self-adjusting hydraulic power units is also constantly improving. Modern self-adjusting hydraulic power units not only have a high degree of adaptability, but also further improve the efficiency and life of the system by adopting new materials, new processes and new technologies. For example, the use of high-efficiency and energy-saving pumps and motors, the use of high-performance hydraulic materials and sealing technology, the introduction of intelligent control strategies, etc. are all typical features of modern self-adjusting hydraulic power units.

[0007] The existing self-adjusting hydraulic power unit is generally an improvement on the traditional hydraulic climbing formwork power unit, which has the problems of inconvenient movement, poor pressure stability and slow climbing formwork speed. For example, a hydraulic climbing formwork power unit disclosed in the authorized Chinese patent CN216241546U can be used in combination with structures such as an oil tank, an integrated oil circuit block, a pressure gauge, a one-way valve, a plug-in direct-acting overflow valve, a mounting base plate, an electric motor, a superimposed double one-way throttle valve, an electromagnetic reversing valve, an air filter, a liquid level and temperature gauge, a gear pump and an oil suction filter to achieve light weight, small size, easy movement, good pressure stability, and the ability to control the climbing formwork speed, thereby improving the sensitivity of the climbing formwork.

[0008] However, when the self-adjusting hydraulic power unit in the above-mentioned cited document is in use, the existing self-adjusting hydraulic power unit is fixed in the installation process by bolts and the mounting base plate. This design defect causes the connection to be not stable enough, and it is easy to shake when subjected to force during operation. This shaking not only affects the normal operation of the hydraulic power unit, but may also cause its structural stress concentration. In the long run, it greatly increases the risk of damage to the hydraulic power unit. At the same time, it is not convenient for the staff to disassemble it later. The bolts need to be unscrewed one by one during disassembly, which results in the use effect of the existing hydraulic power unit to be improved. Utility Model Content

[0033] It should be noted that the driving assembly includes a dual-axis servo motor 4021, a rotating rod 4022 and a bearing support 4023; one side of the dual-axis servo motor 4021 is fixedly mounted on the inner wall of the control box 401, one end of the rotating rod 4022 is fixedly connected to the output shaft of the dual-axis servo motor 4021, and the other end thereof passes through the bearing support 4023, the control box 401 and the driving box 403 in sequence and is connected to the gear transmission assembly, so as to be able to stably drive the gear transmission assembly to rotate.

[0034] It can be understood that one side of the bearing support 4023 is fixedly mounted on the inner wall of the control box 401, and the outer side of the rotating rod 4022 is rotatably connected to the inner side of the bearing support 4023 through a bearing, in order to more stably support the rotation of the rotating rod 4022.

[0035] In addition, the gear transmission assembly includes a driving bevel gear 4041, a driven bevel gear 4042 and a support rod 4043; one side of the driving bevel gear 4041 is fixedly connected to an end of the rotating rod 4022 away from the dual-axis servo motor 4021, the driven bevel gear 4042 and the driving bevel gear 4041 are meshed with each other, the inner side of the driven bevel gear 4042 and the outer side of the support rod 4043 are fixedly connected, and the two ends of the support rod 4043 are rotatably connected to the inner wall of the driving box 403 through bearings, so that the driven bevel gear 4042 meshed on the driving bevel gear 4041 can rotate stably under the drive of the rotating rod 4022, and drive the support rod 4043 to rotate, so as to drive the spur gear 405 to rotate, thereby driving the limit fixing assembly to rotate.

Since the spur gear 405 is meshed with the tooth plate 4061, the tooth plate 4061 is stably moved in the drive box 403 under the sliding connection cooperation between the adjustment block 4081 and the sliding rod 4082 and the meshing and pushing action of the spur gear 405, and the insertion rod 4062 is driven to move under the thrust generated during the movement. When the insertion rod 4062 is separated from the slot 407, the hydraulic power unit body 2 can be separated from the wall 5, so that the hydraulic power unit body 2 can be quickly disassembled.
