Control system for pouring dolly of railway ballast curing device

Abstract

The invention discloses a control system for a pouring dolly of a railway ballast curing device. A detection switching group is connected with a control module. A control module is connected with a touch screen, an execution element, a motion control module, and a servo driver. The motion control module is connected with a digital quantity input / output module. The servo driver is connected with a servo motor. A lifting cylinder up-side switch and a lifting cylinder down-side switch are respectively installed on two ends of a cylinder. A reference point proximity switch detection body is arranged on a side of a dolly frame, close to the end of a pouring dolly electric cabinet. A negative capacity switch detection body is on the other side of the dolly frame, close to the end of the pouring dolly electric cabinet. A positive capacity switch detection body and a reference point proximity switch detection body are on the same side of the dolly frame. A cylinder rising valve and a cylinder lowering valve are arranged on the tip of a tank chain connected with a pouring head. A cylinder rising governing valve and a cylinder lowering governing valve are respectively installed on the upper end and the lower end of the cylinder. The system can realize automatic accurate positioning of pouring points, and pouring amount and flow velocity of the pouring points can be set according to practical construction conditions.

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, there is a control system for pouring trolleys, which cannot be positioned automatically. At the same time, it is inconvenient to adjust the pouring volume and flow rate, which is not conducive to the smooth progress of construction.
