Description
Technical field
The present invention relates to engineering machinery field, particularly a kind of automatic transmission controlling method and pumping equipment of pumping equipment.
Background technique
At present, the pumping mechanism of concrete pumping equipment comprises: master cylinder, water tank, conveying cylinder, concrete piston, shake the main parts size such as valve oil cylinder, stirring system, hopper and S pipe valve and form.As shown in Figure 1: when the pumping state, the hydraulic-pressure pump of main system is to master cylinder 1a, 1b fuel feeding, and under the effect of master cylinder 1a, 1b, concrete piston 4b advances, and 4a retreats.The gear oil pump of reversing mechanism and hydraulic accumulator are together to pendulum valve oil cylinder 5b fuel feeding at this moment, pendulum valve oil cylinder 5b is in the state of stretching out, 5a is in fallback state, by the swing arm effect, S pipe valve 8 is connected concrete conveying cylinder 3b, the concrete of 3b the inside enters conveyance conduit by the S pipe under the promotion of piston 4b; And the piston 4a that the concrete of 7 li in hopper is constantly retreated sucks concrete conveying cylinder 3a.After 4b advanced, and 4a retreats and puts in place, control system was signaled, pendulum valve oil cylinder 5a is stretched out, 5b retreats, and after pendulum valve oil cylinder 5a, 5b commutation put in place, sends signal, make master cylinder 1a, 1b commutation, pushing piston 4a advances, and 4b retreats, and last round of inspiration is carried the concrete in the cylinder 3a to be pushed into S pipe 8 and entered conveyance conduit, simultaneously, carry cylinder 3b suction.So perseveration is finished the pumping of concrete material.During anti-pump, be communicated with S pipe valve 8 by the anti-pump operated concrete cylinder of suction stroke that makes, the concrete cylinder that is in the propelling movement stroke is communicated with hopper, thereby with the concrete pump back hopper in the pipeline.Stirring system 6 is used for the concrete of hopper 7 is stirred again, to the stirring motor fuel feeding, drives the stirring shaft rotation by the stirring system oil pump, to prevent concrete water bleeding segregation and slump loss, guarantees its pumpability.Also comprise boom system for concrete pump, the jib hydraulic-pressure pump drives the stretching, extension of jib to jib hydraulic jack fuel feeding.
Concrete mixer is when travelling gear, and is general by manually variable block realization gearbox shift transformation; But when the pumping state, the general fixedly gear of selecting does not have the variable block function, realizes rate of pumping control by E-Gas control rotating speed or control hydraulic-pressure pump discharge capacity.So that transmission gear is fixed, in pumping state lower time, if load is very little, drive pumping with high rotating speed like this, be unfavorable for energy-conservation; If only by the hydraulic variable displacement pump stepless change, also can only implement than under the small displacement; When sending for large discharge pump, set solid amount output of hydraulic-pressure pump will realize energy-conservation; Generally in when design, the peak output when usually press motor and decide rotating speed designs pump displacement, but pumping under the actual conditions, induced pressure can not all reach capacity, and engine power is wasted.
