Abstract
The invention relates to a control system part of a hydraumatic grouting pump, in particular to a driving lever type reversing mechanism of the hydraumatic grouting pump. The driving lever type reversing mechanism of the hydraumatic grouting pump comprises a main reversing valve which is capable of controlling switchover of a main hydraulic cylinder and is controlled by an auxiliary reversing valve; the auxiliary reversing valve and the main reversing valve are provided with an integrated valve body, and two ends of a valve core of the auxiliary reversing valve are respectively provided with a mandril capable of reciprocating along the valve core; and two ends of a piston rod of the main hydraulic cylinder are respectively provided with a drive plate, and when the piston rod of the main hydraulic cylinder moves to a limiting position of a left-side stroke or a right-side stroke, the drive plate at the corresponding side can drive the mandrils and the valve core of the auxiliary reversing valve to move towards the opposite side through a transmission mechanism. The driving lever type reversing mechanism of the hydraumatic grouting pump, which is provided by the invention, has a simple structure, is convenient to manufacture and install, has high safety, can be suitable to be installed under a coal mine, maintain the advantages of stability and reliability in operation of an electromagnetic directional valve simultaneously, can be obtained through simple modification of the common electromagnetic directional valve, and is beneficial to reduction of manufacturing cost.
Description
Technical field
The present invention relates to a kind of control system parts of hydraulic grouting pump, specifically is a kind of hydraulic grouting pump pole poked type changement.
Background technique
The working principle of common hydraulic grouting pump is: give the oil hydraulic cylinder fuel feeding by hydraulic power unit, promote the slurries cylinder by the master hydraulic cylinder to-and-fro motion, carry slurries through suction, pulp-expelling valve, the to-and-fro motion of master hydraulic cylinder need realize through changement.Hydraulic grouting pump is widely used in water reinforcement under the coal mine; But for this special Environmental Conditions in colliery; Because the switching-over of the consideration oil cylinder of safety should not be adopted the solenoid valve switching-over; The basic at present hand-operated direction valve that adopts is transformed into machine control valve or the complicated oil hydraulic circuit control of employing, but certain narrow limitation is all arranged.1, be transformed into machine control valve for hand-operated direction valve, because of the general pressure of manually operated valve lower (20MPa below) even use the high pressure manually operated valve big, so low oil pressure occasion (the hydraulic system pumping source is a gear pump) in generally can only being applied in because of switching-over hydraulic cutter power.2, through oil hydraulic circuit control, because of needs promote the switching-over of high pressure hydraulic control valve again through mesolow rotary valve control hydraulic oil, structure is complicated, maintenance difficult.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of Security good, be suitable for using in the colliery, hydraulic grouting pump pole poked type changement that reliable in action property is high.
Hydraulic grouting pump pole poked type changement of the present invention includes the main reversing valve that a may command master hydraulic cylinder switches, and said main reversing valve is by an auxiliary selector valve control; The valve body that said auxiliary selector valve and main reversing valve have one, the spool two ends of auxiliary selector valve are provided with the push rod that can move back and forth with spool; The piston rod two ends of said master hydraulic cylinder are respectively arranged with dial; When the piston rod of master hydraulic cylinder moved to the limit position of left side or right side stroke, the spool that the dial of a corresponding side can drive above-mentioned push rod and auxiliary selector valve through driving mechanism was to side shifting.
Said driving mechanism is the driving lever of lever construction.
Said main reversing valve with one valve body and auxiliary selector valve are removed two groups of electromagnet that drive auxiliary selector valve on the basis of conventional solenoid directional control valve, will push rod be set at the spool two ends of auxiliary selector valve again and constitute.
The present invention is simple in structure, manufacturing and easy for installation; Compare common solenoid directional control valve, its auxiliary selector valve partly need not the driving of electromagnetic mechanism, thereby safe, installs applicable under the coal mine, and it has also kept solenoid directional control valve stable operation, reliable advantage simultaneously; In addition, the auxiliary selector valve of its one and main reversing valve can be obtained through simple the transformation by common solenoid directional control valve, help reducing manufacture cost.
