Abstract
The utility model provides a piston type cement mortar pump which uses a piston drive mechanism composed of a cam and a rolling wheel, and a camshaft and an output shaft of a gearbox use one same through shaft; the upper part of a mortar discharge pipe opening of a pump head is additionally provided with a buffering pressure regulating cylinder, and a side body of the pump head is connected with a pressure relief valve. With the advantages of novel structure and stable outputted mortar flow, the utility model is suitable for the conveying and pouring of neat cement grout and various cement mortars of which the sand diameter is below 5 millimeters.
Description
The utility model relates to a kind of pump, especially a kind of reciprocating pump of carrying the cement injection mortar that is exclusively used in.
In building engineering construction, often need the cement bonded sand stock pump to carry the cement injection mortar.Existing cement bonded sand stock pump mainly is made up of the pump housing, motor, speed changer, connecting rod, liquid feeding pump head and piston, it constructs complicated heaviness, defeated slurry is unstable, using scope is narrower, be applicable to more and carry perfusion neat slurry or fine sand slurry, the material of perfusion of carrying is restricted, and brings inconvenience to use.
The purpose of the utility model provides a kind of novel structure, pulp novel concrete mortar pump even, applied widely, easy to use.
For achieving the above object, the technical solution adopted in the utility model is: the driving mechanism that will connect motor transmission and piston adopts the driving mechanism of being made up of cam and roller, the cam load is on transmission output shaft, and cam is the company's of touching roller movingly, and roller connects the connecting rod of piston.And at the pulp mouth of pipe top reload buffer pressure regulation tube of pump head.During use, motor drives the cam rotation by speed changer, driving mechanism becomes the straight reciprocating motion of piston in pump cylinders with rotatablely moving of cam, carries out the conveying perfusion operation of slush, and the pressure regulation tube of pump head can still have mortar output when backward stroke of the piston is inhaled slurry.
Cooperate the driving mechanism of forming because the utility model has adopted by cam and roller, cam both is installed in directly on the transmission output shaft that camshaft and transmission output shaft are same axis, also adds to be shaped on pump head to regulate tin.Therefore, the utility model is than existing slush pump structure novelty, reasonable, even, the pressure stability of output mortar flow of structure, applied widely, both can be used for neat slurry, especially can be applicable to the conveying perfusion of the various slush of sand grains diameter below 5 millimeters, easy to use, it is applicable to rockfill grouting, injection grout, pile foundation anchor grouting of engineerings such as building foundation, tunnel, bridge etc., is a kind of novel cement bonded sand stock pump.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the sectional view of the utility model embodiment concrete structure.
Fig. 2 is the plan view of Fig. 1.
