Abstract
The utility model discloses a three-cylinder reciprocating high-pressure grouting pump. A motor, a gearbox, a speed reducer and a shell of the grouting pump are fixed to a pump base; a gear transmission crankshaft in the shell is connected with crank connecting rod assemblies, the top ends of slide blocks of the assemblies are connected with plunger rods, the other ends of the plunger rods are connected with plungers capable of moving in cylinder bodies in a reciprocating way, and the cylinder bodies are fixed to the left end of the shell; three sets of cylinder bodies, plungers, plunger rods and matched crank connecting assemblies are provided; valve bodies are arranged at the two ends of the upper portions of the cylinder bodies respectively, and slurry-absorbing valves and slurry draining valves are arranged inside the valve bodies. The motor is used for driving a gear to rotate, the crank connecting rod assemblies are used for driving the plungers to move in the cylinder bodies in a reciprocating way, and slurry absorbing and draining are realized under the actions of ball valves in the slurry-absorbing valves and slurry draining valves. The grouting pump has the advantages of high slurry discharge capacity, stable pressure, compact structure, convenience in maintenance and low cost. Through reciprocating movement of the plungers, three cylinders are equivalent to six cylinders in power, thereby greatly increasing the working efficiency.
Description
One, technical field
The utility model relates to a kind of high-pressure injection pump, especially a kind of three cylinder reciprocating high-pressure injection pumps.
Two, background technique
Current, in the foundation construction engineering of mine, well tunnel, carry out foundation ditch strengthening processing and slope protection construction, the reinforcing of all types of bored tunnels of all types of foundations, Geotechnical Engineering and the orientation of anti-sealing, building and structures sedimentation and inclination is raised and the construction such as correction, all by grouting pump realize grouting for water blocking, support with backfilling is implemented, so not only improve speed of application, also improved construction quality., the plunger type grouting pump of application in the past, its structure is to be all made up of two cylinder bodies, connecting rod, piston that drive plunger moves are two covers.Two cylinder structure one is in the time that the limit position of suction one plasma discharge is changed moment, to have disconnected slurry phenomenon, causes defeated slurry pressure transient; The 2nd, what suction, pulp-expelling valve had is located in casing, safeguards, changes and inconvenience; What have is located at outside casing, but because pulp absorbing valve, pulp-expelling valve are split type, takes up room large, complex structure, and cost is high.
Three, summary of the invention
In order to solve the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of defeated slurry pressure stability, flow are large, compact structure, be convenient to three cylinder reciprocating high-pressure injection pumps of maintenance.
The technological scheme that realizes the purpose of this utility model employing is: this high-pressure injection pump is mainly made up of pump seat, motor, coupling, gearbox, speed reducer, housing, cylinder body, plunger, plunger rod and valve body; Motor is connected with gearbox input shaft, the output shaft of gearbox is connected with the input shaft of speed reducer by coupling, the output shaft of speed reducer is connected with the driving gearshaft in housing by coupling, and motor, gearbox, speed reducer, housing are fixed on pump seat; On gear transmission bent axle in housing, be connected with crank rod assembly, the slide block top of assembly is connected with plunger rod, the other end of plunger rod be connected with can be in cylinder body reciprocating plunger, the left end of housing is fixed with cylinder body; Described cylinder body, plunger, plunger rod and with it supporting crank rod assembly are three covers; Valve body is equipped with respectively at the two ends on described cylinder body top, and valve inner is provided with pulp absorbing valve and pulp-expelling valve, and outside is connected to pulp absorbing hole and plasma discharge mouth, thereby forms three cylinder reciprocating high-pressure injection pumps.The rotation of motor driven gear, drives crank rod assembly motion to make plunger to-and-fro motion in cylinder body, realizes suction, plasma discharge by the ball valve effect in suction, pulp-expelling valve.
The beneficial effects of the utility model are: the cylinder body of this grouting pump, plunger, plunger rod and with it supporting crank rod assembly are three covers, can make up two cylinder structure has the deficiency of disconnected slurry phenomenon in the time that the limit position of suction one plasma discharge is changed moment, also guarantees the stable of defeated slurry pressure when having strengthened plasma discharge amount; Cylinder body, valve body are arranged on outside housing, and easy access is safeguarded and changed, is unlikely to cause entirety to be scrapped, thereby reduced maintenance cost; Integrated valve body structure is simple, compact, takes up room little, has reduced cost.So this high-pressure injection pump plasma discharge amount is large, pressure stability, compact structure, easy to maintenance, plunger moves back and forth three cylinders and all does work and be equivalent to six cylinder workings, and working efficiency improves greatly.
Four, accompanying drawing explanation
Fig. 1 is the plan structure figure of the utility model three cylinder reciprocating high-pressure injection pumps.
Five, embodiment
In the accompanying drawings, for the utility model three cylinder reciprocating high-pressure injection pumps are mainly made up of pump seat, motor, coupling, gearbox, speed reducer, housing, cylinder body, plunger, plunger rod and valve body; Motor 1 is connected with the input shaft of gearbox 2, the output shaft of gearbox 2 is connected with the input shaft of speed reducer 4 by coupling 3, the output shaft of speed reducer 4 is connected with the driving gearshaft in housing 5 by coupling, and motor 1, gearbox 2, speed reducer 4, housing 5 are fixed on pump seat; On gear transmission bent axle in housing 5, be connected with crank rod assembly, the slide block top of assembly is connected with plunger rod 6, and the other end of plunger rod 6 is connected with can be at the interior reciprocating plunger 10 of cylinder body 11, and cylinder body 11 is fixed on the left end of housing 5; Described cylinder body 11, plunger 10, plunger rod 6 and with it supporting crank rod assembly are three covers; Valve body 9 is equipped with respectively at the two ends on described cylinder body 11 tops, and valve body 9 inside are provided with pulp absorbing valve and pulp-expelling valve, and outside is connected to pulp absorbing hole 8 and plasma discharge mouth 7, thereby forms three cylinder reciprocating high-pressure injection pumps.The rotation of motor driven gear, drives crank rod assembly motion to make plunger to-and-fro motion in cylinder body, realizes suction, plasma discharge by the ball valve effect in suction, pulp-expelling valve.
