Abstract
The invention relates to a spring-boosted triggering delay reversing pneumatic grouting pump. The existing pneumatic grouting pump has the problems that the grouting pump also adopts the spring-boosted triggering reversing mechanism, but the problem of reversing dead point exists, and cannot be easily solved; when the grouting pump runs at high speed, the dead point problem is not obvious; when the grouting pump runs at low speed, the shutdown frequently occurs; although multiple pneumatic grouting pumps can solve the problem of reversing dead point, a plurality of pneumatic valves need to be used, namely that two travel valves, one pilot valve and one reversing valve are arranged; although the gas passing amounts of the travel valves and the pilot valve are less, when the cleanliness of the compressed air is lower, the easiness in blockage occurs, and the influence on the normal running of the grouting pump is caused; the cleanliness of the compressed air of the coal mine is lower, and the fault rate of the equipment is higher. The spring-boosted triggering delay reversing pneumatic grouting pump has the advantages that a shift rod mechanism is used for driving the spring-boosted triggering delay triggering mechanism to control a two-position and five-way slide cutoff valve, so as to switch an air inlet of the air cylinder; as the delay reversing is adopted, the problem of reversing dead points is solved, only one pneumatic valve is arranged, and the reliability is higher.
