Problems solved by technology

[0005] Hydraulic motors and hydraulic pumps will inevitably wear out after long-term operation, resulting in looseness and gaps in the components of the hydraulic device, causing the device to vibrate and further generating noise
The traditional method to reduce or eliminate the noise of hydraulic motors and hydraulic pumps is to replace better hydraulic pumps and optimize hydraulic pipelines. This traditional method is costly and takes a long time

Abstract

The invention discloses a clamping control system and method for a lagging jack mounting trolley. The system comprises the trolley, an actuating mechanism enabling valve (2) and an actuating mechanism unloading valve (4) are arranged on an actuating mechanism (7) of the trolley, and the actuating mechanism enabling valve (2) and the actuating mechanism unloading valve (4) are both connected with a controller (5); a clamping device (1) is arranged on an arm support (8) of the trolley, the clamping device (1) is connected with a clamping pressure sensor (3), and the clamping pressure sensor (3) is further connected with the controller (5); and a display (6) is arranged in an operation room of the trolley and is connected with the controller (5). Noise of a hydraulic system of the trolley during working can be greatly reduced, and thus a comfortable operation environment is provided for an operator.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a clamping control system and method for an arch mounting trolley. Background technique [0002] At present, my country's highway tunnels, railway tunnels and soft rock tunnels are still in the early stage of tunnel construction mechanization, and the overall technology is still lagging behind developed countries. The mechanized rapid construction technology system based on the drill-and-blast method has not yet been completed, and the key technical problems in supporting equipment have not yet been broken through. The construction progress varies greatly, and there are many hidden dangers of accidents during the construction process. The main construction equipment on its operation line is mostly imported from abroad, and the self-developed varieties are relatively small, with poor quality and high failure rate, and the main technical performance parameters do not ...
