The hydraulic lifting platform for vehicle loading and unloading is a hydraulic transmission system type loading and unloading machine equipment installed at the rear of large trucks and various sealed vehicles. This machine equipment can be used for loading and unloading goods, as well as serving as an electric tailgate for box trucks, hence it is also known as a car tailgate. It uses a small battery as its energy source and works in conjunction with a forklift or manual forklift. With simple real-time control, it can easily load and unload several tons of goods. The hydraulic lifting platform for vehicle loading and unloading has the characteristics of compact structure, wide working range, high working efficiency, and reliability, and can be widely used for loading and unloading work on road transport vehicles.
1、 Introduction to hydraulic lifting platform for vehicle loading and unloading
1. Principle
The hydraulic lifting platform for vehicle loading and unloading adopts the hydraulic drive method. According to the required battery of the freight vehicle, the DC motor power supply system drives the high-pressure water pump, converting the electromagnetic energy of the battery into high-pressure hydraulic energy of hydraulic oil. The relay is used to operate the hydraulic cylinder for fitness movement, converting the high-pressure hydraulic energy into mechanical kinetic energy. The four mechanical structures of the drive are used for fitness movement, thereby enabling the passenger service platform to perform various postures such as upward and downward translation and upward and downward rotation.
2. Construction composition
The key components of the hydraulic lifting platform for vehicle loading and unloading include oil source control equipment, control board, hydraulic cylinder, lifting arm, square steel pipe, service platform, etc.
2、 Key points of the design scheme
1. Design scheme of executing mechanism
The overall design is a key step in the design scheme of the hydraulic lifting platform for vehicle loading and unloading, and selecting and clarifying the executing mechanism is important. According to the function of the hydraulic lifting platform for vehicle loading and unloading, the actuator should have the characteristics of upward and downward translation and rotation, that is, the passenger service platform should also perform flat fitness exercises according to certain regularity.
2. Clarify the specifications of the executing organization
Based on the calculation of support and the load-bearing condition of the passenger service platform, as well as the lifting height to width ratio of the hydraulic lifting platform, and according to the structural specifications of the rear end of the vehicle, the organization of the transmission system angle, and the compressive strength standards of the hydraulic cylinder, the relevant specifications of the actuator can be basically clarified, thus clarifying the actual structure.
3. Design Scheme of Hydraulic Automatic Control System
The design scheme of the hydraulic automatic control system is another key step in the design scheme of the hydraulic lifting platform for vehicle loading and unloading, and selecting and clarifying the hydraulic control circuit is important.
4. Clarify the oil source control equipment
Based on the hydraulic cylinder pressure and total flow rate during operation, determine the system software pressure and flow rate. Select the hydraulic pump, hydraulic cylinder, hydraulic valve, control board and its hydraulic pipes, hydraulic oil, etc., and then select the motor output power based on the output power of the hydraulic pump (referring to the amount of work done by the block during the enterprise time). At this point, the entire hydraulic automatic control system is clear.
The hydraulic lifting platform equipment for vehicle loading and unloading has been operating normally since its installation and application. It has been confirmed that the hydraulic lifting platform for vehicle loading and unloading has stable characteristics and can compete with peers in the same industry around the world. In addition, its price is less than half of similar foreign products. If gradually promoted and applied, it will save the country a lot of foreign exchange transactions. Not only does it have rationality, but it also has applicability.
