Abstract

The invention discloses an integral automatic adjustment device of a tunnel trolley template. The device comprises a hydraulic cylinder elongation detector, a control unit, a hydraulic system and a template system, wherein the hydraulic cylinder elongation detector is a magnetostriction sensor installed inside a hydraulic cylinder and is used to monitor an elongation of the hydraulic cylinder in real time; the control unit comprises a PLC, is used to control the flow rate and flow direction of inflows entering the hydraulic cylinder, and can automatically adjust the flow rate and flow direction of the inflows entering the hydraulic cylinder according to a comparison result of a hydraulic cylinder elongation target value and a feedback value; the hydraulic system receives an instruction sent by the control unit, carries out rapid feeding, work feeding and retreating of the hydraulic cylinder and can ensure that the template can be locked rapidly and reliably when the hydraulic cylinder does not work or fails; the hydraulic cylinder is connected to the template and a pressure relay upright by hanging lugs respectively; and the template system changes working positions according to the different elongations of the hydraulic cylinder. According to the invention, the automation degree is high; adjustment is accurate; operations are simple; and the labor cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of adjusting the position of the steel mold of the tunnel trolley, in particular to an integral automatic adjustment device for the formwork of the tunnel trolley. Background technique [0002] Tunnel trolley is a kind of mechanical equipment for secondary lining in tunnel construction, and it is widely used in railways, highways and water conservancy and hydropower projects. This equipment can not only improve the quality of concrete lining, but also speed up the construction progress and improve work efficiency. During the tunnel construction process, due to the different types of surrounding geological rocks and the different sizes of the inner diameter of the tunnel, the formwork system of the tunnel trolley should be able to adjust its working position in time according to different working environments. In the construction process at this stage, multiple hydraulic pumps are usually used to drive multiple hydrau...
