Abstract

The invention relates to the technical field of control over operations of construction devices, in particular to a system and method for controlling synchronous operations of multiple hydraulic actuating elements and a climbing frame. By means of the system and method for controlling synchronous operations of the multiple hydraulic actuating elements and the climbing frame, after it is detected through a pressure sensor that the pressure on the hydraulic actuating elements is equal to the preset pressure value on the control system, zero clearing is performed on the displacement of the one-to-one corresponding hydraulic actuating elements; after the current displacement of the hydraulic actuating elements is detected through a displacement sensor, the maximum real-time actually-measured displacement value of all the hydraulic actuating elements is obtained, and all the hydraulic actuating elements are controlled to synchronously work after the current displacement of all the hydraulicactuating elements is controlled to be equal to the maximum displacement value through a control device; and when the operations of a hydraulic system of the construction climbing frame are controlled through the method, the whole climbing frame is controlled by the hydraulic actuating elements to synchronously rise, and the existing requirements for climbing or falling of the construction climbing frame are met.

Description

technical field [0001] The present invention relates to the technical field of controlling the operation of construction equipment, and in particular to a control method for synchronous operation of multiple hydraulic actuators. Based on the control method for synchronous operation of multiple hydraulic actuators, the present invention also provides a synchronous operation of multiple hydraulic actuators. A control system and a climbing frame using a plurality of hydraulic actuators to synchronously operate the control system and method. Background technique [0002] Climbing frames are also called lifting frames. According to their power sources, they can be divided into main types such as hydraulic type, electric type, and manual pull type; climbing frames are a new type of scaffolding system developed in recent years, which can climb up or down along the building , mainly used in high-rise shear wall buildings. The climbing frame is mainly composed of climbing frame guid...
