Abstract

The invention discloses a method and device for controlling an electric support frame for a trailer. The electric support frame includes a motor, a speed regulating device, a control unit, a limit device, a driving device, a transmission device, and a support frame. Or drop the start signal to control the forward or reverse rotation of the motor. The limit device gives the initial position signal and starts position recording. After the motor rotates through the speed regulating device, it drives the driving device to move, and the movement of the driving device drives the transmission device. movement, thereby controlling the rise or fall of the electric support frame; when the position record in the limit device reaches the end point, a signal of reaching the highest position or the lowest position is sent, and the control unit controls the motor to stop running after receiving the position signal; the speed regulating device, The driving device and the transmission device are operated by gear meshing. The motor is used to drive the rising or falling of the supporting frame, which realizes the all-weather work of the supporting frame and ensures the safe operation of the supporting frame.

Description

technical field

[0001] The invention relates to the technical field of a trailer support frame, in particular to a control method and device for an electric support frame for a trailer. Background technique

[0002] At present, trailers or semi-trailers, for example, need to use support frames when connecting or unloading trailers or semi-trailers. The current electric support mostly adopts electro-hydraulic control mode, and the support is raised or lowered through the hydraulic system. Although Hydraulic transmission has many advantages, but its disadvantages cannot be ignored. Disadvantage 1. Hydraulic transmission uses liquid as the working medium, and leakage cannot be avoided during the relative movement of hydraulic components. Coupled with the compressibility of liquid, it is difficult to achieve a strict transmission ratio; Disadvantage 2 1. Liquid viscosity is closely related to temperature. When viscosity changes with temperature, it will directly affect leakage, ...
