Abstract
The utility model provides a symmetrically-arranged four-cylinder reciprocating motion high-pressure grouting pump. A motor, a gearbox, a speed reducer and shells of the pump are fixed to a pump base. Gear transmission crankshafts in the shells are connected with crank connecting rod assemblies. The top ends of sliding blocks of the crank connecting rod assemblies are connected with plunger rods. The other ends of the plunger rods are connected with plungers which can do reciprocating motion in cylinder bodies. Cylinder bodies are fixed to the tail ends of the shells. The shells of the pump and the parts matched with the shells of the pump are divided into two sets, and the two sets of the shells and the parts matched with the shells are symmetrically arranged on the two sides of the speed reducer. Valve bodies are arranged at the two ends of the upper portion of each cylinder body respectively. A grout suction valve and a grout discharge valve are arranged in each valve body. The motor drives gears to rotate so as to drive the crank connecting rod assemblies to move to enable the plungers to do reciprocating motion in the cylinder bodies; grout suction and grout discharge are achieved through ball valves in the grout suction valves and ball valves in the grout discharge valves. The grouting pump is balanced in stress of the parts, long in service life, large in grout discharge quantity, stable in pressure, compact in structure, convenient to maintain and low in cost; work of four cylinders is equivalent to work of eight cylinders because the plungers do reciprocating motion, and accordingly the working efficiency is greatly improved.
Description
One, technical field
The utility model relates to a kind of high-pressure injection pump, and especially one is arranged symmetrically with formula four cylinder to-and-fro motion 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 structural configuration majority is that a side is power-transmitting part, as motor, gearbox and speed reducer, opposite side is grouting pump.The deficiency of this kind of structural configuration is that the driving force that bears of motor, gearbox, particularly speed reducer is unbalanced, causes transmission part generation eccentric wear phenomenon, causes related components to reduce working life.In addition, the suction, the pulp-expelling valve that adopt are located in casing, safeguard, change 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 a kind of power transmission equilibrium, improves part life, and defeated slurry flow is large, the formula that the is arranged symmetrically with four cylinder to-and-fro motion high-pressure injection pumps of pressure stability.
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 tail end of housing is fixed with two cylinder bodies; Described speed reducer is provided with two symmetrical output shafts, and the housing of its pump and with it supporting component are the both sides that two covers are arranged symmetrically in speed reducer; 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, is arranged symmetrically with formula four cylinder to-and-fro motion high-pressure injection pumps thereby form.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: because the two cover pump housings of this grouting pump are arranged symmetrically in the both sides of speed reducer, when work, cause related components stress equalization, eccentric wear phenomenon can not occur, thus the working life of having improved complete machine.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; Due to inhale, pulp-expelling valve adopt be integrated valve body structure, simple in structure, compact, take up room little, reduced cost.So, this high-pressure injection pump component stress equalization, long service life, plasma discharge amount is large, pressure stability, compact structure, easy to maintenance, plunger moves back and forth four cylinders and all does work and be equivalent to eight cylinder workings, and working efficiency improves greatly.
