Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] In order to realize the control of the tension solenoid valve flexibly and reliably, ensure that the tension of the scraper chain is within a certain reasonable range, neither the tension is too small to cause failures such as chain drop or jamming, nor is the tension too large to cause abrasion of the scraper , broken chain and other faults, this embodiment relates to a control method for the tail tension solenoid valve of scraper machine, see Figure 1 to Figure 3 As shown, the specific description is as follows.

[0028] S1: Determine whether the tension sensor and the displacement sensor are faulty. If both are faulty or only the displacement sensor is faulty, control the tension solenoid valve to lock and return to S1. If only the tensi...

Abstract

The invention discloses a control method for a tensioning solenoid valve at the tail of a scraper machine, including: S1: if at least a displacement sensor fails, the tensioning solenoid valve is locked, and returns to S1; if only the tension sensor fails, controls the loading and unloading valve, and returns to S1. S1; if there is no fault, go to S2; S2: Do you need to adjust the tension? Clear the adjustment flag, go to S4, if not, go to S4; S4: Whether the tension adjustment flag is enabled, if not, lock the tension solenoid valve, return to S1, if so, control the loading and unloading valve according to the real-time tension and tension target value, Return to S1. The invention is used to solve the problems of slow response speed and poor control reliability of the step-by-step time-delay control tension solenoid valve.

Description

technical field [0001] The invention relates to the technical field of scraper machines, in particular to a control method for a tail tension solenoid valve of scraper machines. Background technique [0002] Scraper conveyor (referred to as scraper conveyor), as the main transportation equipment in the fully mechanized mining face, is developing towards the direction of large capacity, long distance and high power. The scraper chain is one of the important components of the scraper conveyor. As the traction mechanism of the scraper conveyor, the scraper chain restricts the normal operation of the scraper conveyor, and at the same time affects the safety and production of the mine. In order to ensure that the scraper chain adapts to the change of load and make the chain work in a moderately elastic state, it is necessary to adjust and precisely control the chain tension of the scraper conveyor in real time. [0003] The tail cylinder of the scraper machine is connected to th...
