Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mines, in particular to a monitoring and redundancy device for a proximity switch of a filling pump swing cylinder. Background Art
[0002] During mine filling, the left and right delivery cylinders of the filling pump alternately suck in and pump out materials under the drive of two hydraulic cylinders. That is, when the input end of the S-shaped swing valve is opposite to the left delivery cylinder under the push of the swing cylinder, and the right delivery cylinder is connected to the hopper, the pressure oil of the main oil pump enters the rodless chamber of the left hydraulic cylinder, the piston of the left hydraulic cylinder is pushed out, and drives the piston of the left delivery cylinder to extend to produce a pumping action. The material in the left delivery cylinder is pumped into the delivery pipeline through the S-shaped swing valve.
[0003] At the same time, the hydraulic oil in the rod chamber of the left hydraulic cylinder flows through the pipeline connecting the left and right hydraulic cylinders into the rod chamber of the right hydraulic cylinder, pushing its piston back. This in turn causes the piston of the right delivery cylinder to move backward, creating suction and drawing material from the hopper into the right delivery cylinder. When the piston of the right delivery cylinder is about to reach the end of its motion, the sensing sleeve installed between the main hydraulic cylinder and the delivery cylinder reaches below the proximity switch in the washing chamber. The sensing information from the sensing sleeve on its connecting rod is received by the proximity switch, and the PLC sends an electrical signal to reverse the direction of the solenoid valve in the swing cylinder, redirecting the pressure oil output from the swing oil pump to the other swing hydraulic cylinder, rotating the S-shaped swing valve and connecting its feed port to the other material cylinder. Simultaneously, the PLC also sends a reversal signal to the solenoid valve, causing the pressure oil output from the pump to enter the rodless chamber of the right master hydraulic cylinder, completing the opposite action of the previous master cylinder.
[0004] At this point, the concentrated material in the left delivery cylinder has been completely pressed into the delivery pipeline through the S-shaped swing valve, and the right delivery cylinder has been fully aspirated, completing a working cycle. This reciprocating cycle achieves automatic pumping. Because the left and right main oil cylinders continuously and alternately complete their respective suction and delivery strokes, the material in the hopper is continuously delivered to the delivery pipeline through the S-shaped swing valve, completing the pumping operation.
[0005] During use, it was found that the design position of the proximity switch was flawed. It was located in a hidden and small space, making it difficult, time-consuming and labor-intensive to replace. The operating environment was harsh and it was easily covered by mud, causing malfunctions. At the same time, the proximity switch was an imported professional accessory, which was expensive and had a long delivery cycle, which directly restricted the operating reliability of the equipment during filling.
