Abstract
The utility model relates to a hydraulic double-fluid grouting pump, in particular to a grouting pump for grouting water plugging and gap filling during well building and underground waterproof engineering in gas and coal mines. A motor drives a gear pump to rotate, high pressure oil is sent into an oil cylinder after passing through an overflow valve and a reversing valve, the high pressure oil is driven to make a reciprocating motion in the oil cylinder through a reversing mechanism, and simultaneously, a piston rod is utilized to drive a piston in a grouting cylinder to make a synchronous reciprocating motion, therefore, the grouting is realized. The grouting pump has the advantages that the grout coagulation time can be mastered, the pressure is regulated automatically, and the use is convenient.
Description
Technical field
The utility model relates to a kind of grouting pump, particularly is applicable to the cutting and the maintenance in coal containing methane gas ore deposit, shaft building and down-hole waterproofing project, tunnel, builds the Hydraulic Double liquid grout pump of dam, large bridge, high rise building foundation processing and all kinds of underground engineerings.
Background technique
At present, the grouting for water blocking during gassy colliery both domestic and external, shaft building and down-hole waterproofing project, Large-scale Railway and vcehicular tunnel, reservoir dam basis, high-rise are basic, filling the grouting reinforcement of space, broken rock, all is to be implemented by grouting pump.Like this, not only improve speed of production, also improved structural quality simultaneously.But original grouting pump is in the set time of slurries, and the grouting pressure aspect all can't control voluntarily, do not reach original slip casting effect.
Summary of the invention
The purpose of the utility model provides a kind of realization two fluid grouting, and the set time that can operate slurries is simultaneously according to the Hydraulic Double liquid grout pump of being regulated pressure by the rock stratum situation of slip casting voluntarily.
The utility model the utility model is realized through following approach: this Hydraulic Double liquid grout pump is made up of permissible motor, coupling, gear oil pump, fuel tank, split type control valve (relief valve, unloading valve, selector valve), oil cylinder, slip casting cylinder, valve chamber, changement, high-pressure rubber pipe, return tube, water cooler, pulp-absorbing pipe, suction slurry halter, discharge pipe, mixer, anti-shock pressure meter.Motor is through the coupling transmission, and the driving gear pump rotation sucks gear pump and discharge with the hydraulic oil in the fuel tank, and the high pressure oil of discharge is sent into oil cylinder through relief valve, selector valve, high-pressure oil pipe, promotes in-oil cylinder piston, makes its to-and-fro motion.Oil return flows into water cooler through return tube, returns fuel tank after cooling off and accomplishes a circulation, and oil cylinder links to each other with the slip casting cylinder through piston rod; So two-cylinder piston is done synchronous to-and-fro motion; Thereby make slurries through suction, plasma discharge pipeline and valve chamber, suck also and discharge, slurries are injected in the injected hole.
The slip casting cylinder of above-mentioned Hydraulic Double liquid grout pump can respectively connect a valve chamber at two ends, realizes slip casting through the reciprocating motion of the pistons in the slip casting cylinder.Install the valve of sizing mixing additional between slurry elbow of the suction of a valve chamber therein and the pulp-absorbing pipe during two fluid grouting, this valve of sizing mixing can be regulated flow arbitrarily, to reach desired proportioning.
The anti-shock pressure meter of above-mentioned Hydraulic Double liquid grout pump is provided with two anti-shock pressure meters, and a side that is installed in relief valve is used for measuring the pressure of pressurized oil system; Another piece is installed on the mixer, is used for measuring the pressure of slurries.The anti-shock pressure meter impact resistance especially is used on single duplex double action pump than the strong manyfold of ordinarily manometer, and superiority is significantly arranged, thereby can reflect the working state of pump accurately.
The split type control valve of above-mentioned Hydraulic Double liquid grout pump is made up of relief valve, unloading valve and two-position four way change valve; Relief valve and unloading valve can be made pressure regulator valve can make safety valve usefulness again; Its effect can in the nominal pressure scope, set up grouting pressure arbitrarily, and the ability pilot pressure be constant as required; But restriction pressure raises again simultaneously, plays safety effect.The high pressure oil that flows out through gear pump flows into oil cylinder through two-position four way change valve, utilizes oil pressure that in-oil cylinder piston is moved reciprocatingly, make switching-over flexibly, quick, accurately, reliable.
The utlity model has advantage: the utility model is all-hydraulic, and single, double liquid is dual-purpose, the adjustable-pressure grouting pump.It is little to have volume, in light weight, and flexibility and reliability can be grasped the set time of slurries voluntarily, characteristics such as is widely used.
