A pouring trolley control system for railway track bed solidification equipment

Abstract

The invention discloses a pouring trolley control system for railway track bed solidification equipment. A detection switch group is connected to a control module. The control module is respectively connected to a touch screen, an actuator, a position control module and a servo driver, and the position control module is connected to a digital input / output module. , the servo driver is connected with the servo motor; the upper switch of the lifting cylinder and the lower switch of the lifting cylinder are installed at both ends of the cylinder, the reference point proximity switch detection body is set on the side of the trolley frame near the electric control box end of the pouring trolley, and the detection body of the negative limit switch is at the The other side of the trolley frame near the end of the electric control box of the pouring trolley; the positive limit switch detection body and the reference point proximity switch detection body are on the same side of the trolley frame; the cylinder up valve and cylinder down valve are set on the tank chain connected to the pouring head The end, the cylinder ascending speed regulating valve and the cylinder descending speed regulating valve are installed at the upper and lower ends of the cylinder respectively. It can realize the automatic and accurate positioning of the pouring point, and the pouring volume and flow rate of the pouring point can be set according to the actual construction situation.

Description

technical field [0001] The invention relates to a pouring trolley control system for railway track bed curing equipment, belonging to the technical field of railway pouring. Background technique [0002] At present, my country's railway ballast bed mainly includes ballasted track bed and ballastless track bed. The ballasted track bed is a loose material, and its elastic modulus and internal friction angle vary greatly with the difference in transportation volume and dirtiness of the ballast track. , so the maintenance cycle is short, requiring a large number of maintenance personnel, time-consuming and labor-intensive, and affecting the normal operation of the railway; the ballastless track is a track structure that uses an integral concrete structure to replace the sleepers and granular gravel bed in the traditional ballasted track. A track bed structure with less maintenance workload, strong integrity, and clean surface. At the same time, because the integral track bed is co...

Problems solved by technology

At present, the control system for the pouring trolley cannot be positioned automatically, and it is inconvenient to adjust the pouring volume and flow rate, which is not conducive to the smooth progress of construction
