This grouting pump reaches the effect that the thick liquid was arranged in the pulsation.
Description
Technical field
The utility model belongs to engineering construction equipment technical field, specifically relates to a kind of for grouting slip casting pump structure in engineering construction.
Background technique
At present, the underground project waterproof such as tunnel, subway, major fault, solution cavity, highway foundation are reinforced, Hydropower Dam leak stopping and reinforcing, tunnel seals, and landslide is repaired, above ground structure grouting and consolidation on foundation, all kinds of mortar depositing constructions such as side slope suspension roof support, generally use hydraulic grouting pump; Its structure mostly adopts single-cylinder dual-action automatic reciprocal cylinder to drive both sides fluid end plunger reciprocates to reach the object of suction, plasma discharge.
The plunger diameter that automatic reciprocal cylinder two ends piston rod connects is identical, and the slurry pressure that its both sides export is also substantially identical with flow, and the overall discharge of slurries is relatively steady.
And in practice of construction, according to the complexity on stratum and the technical requirements of reinforcing, need grouting pump can meet following requirement: 1) high pressure, small displacement slip casting; 2) low pressure, huge discharge slip casting; The two work that hockets.
Summary of the invention
For the deficiencies in the prior art, the utility model provide a kind of simple and reasonable, manufacture cost is lower, strong adaptability, plasma discharge of pulsing hydraulic grouting pump structure.The technical solution adopted in the utility model is:
To pulse the hydraulic grouting pump structure of plasma discharge, comprise automatic reciprocating hydraulic oil cylinder, connecting sleeve, left midge room, right midge room, discharge pipe, ball valve, pulp-absorbing pipe;
The two ends, left and right of automatic reciprocating hydraulic oil cylinder by connecting sleeve respectively with the end winding support of left midge room and right midge room; Left midge room connects discharge pipe and pulp-absorbing pipe respectively by the ball valve above and below it; Right midge room connects discharge pipe and pulp-absorbing pipe respectively by the ball valve above and below it;
The utility model also comprises:
Large plunger, large cylinder head and small plunger, little cylinder head, and large plunger sealing washer and small plunger seal ring; The diameter of large plunger is greater than the diameter of small plunger; Large plunger matches with large cylinder head, and small plunger matches with little cylinder head;
Left midge room is in large cylinder head, is sealed and be slidably matched between large plunger and large cylinder head by large plunger sealing washer; Right midge room is in little cylinder head, is sealed and be slidably matched between small plunger and little cylinder head by small plunger seal ring; Be provided with piston rod about automatic reciprocating hydraulic oil cylinder, the piston rod of automatic reciprocating hydraulic oil cylinder both sides is positioned at connecting sleeve inside, and is connected with large plunger and small plunger respectively.
Further, the diameter of left midge room and right midge room is greater than the diameter of ball valve inner passage.
The utility model has the advantage of: the utility model have employed the structure of large and small diameter due to the plunger of the left and right sides, the pressure that its sectional area difference makes it export and discharge capacity have a marked difference, be provided with one end high pressure, small displacement, the characteristic that the other end low pressure, huge discharge export, meets the requirement of construction.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model composition schematic diagram.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
The hydraulic grouting pump structure of the pulsation plasma discharge that the utility model proposes, as shown in Figure 1, comprising: automatic reciprocating hydraulic oil cylinder 1, connecting sleeve 2, large plunger 3, large cylinder head 4, small plunger 5, little cylinder head 6, left midge room A, right midge room B, discharge pipe 7, large plunger sealing washer 8, ball valve 9, pulp-absorbing pipe 10, small plunger seal ring 11;
The two ends, left and right of automatic reciprocating hydraulic oil cylinder 1 by connecting sleeve 2 respectively with the end winding support of left midge room A and right midge room B; Left midge room A connects discharge pipe 7 and pulp-absorbing pipe 10 respectively by the ball valve 9 above and below it; Right midge room B connects discharge pipe 7 and pulp-absorbing pipe 10 respectively by the ball valve 9 above and below it;
The utility model left and right sides plunger is asymmetric, can obtain the slurries of left-right asymmetry pressure; The diameter of large plunger 3 is greater than the diameter of small plunger 5; Large plunger 3 matches with large cylinder head 4, and small plunger 5 matches with little cylinder head 6;
Left midge room A is in large cylinder head 4, is sealed and is slidably matched between large plunger 3 and large cylinder head 4 by large plunger sealing washer 8; Right midge room B is in little cylinder head 6, is sealed and be slidably matched between small plunger 5 and little cylinder head 6 by small plunger seal ring 11; Automatic reciprocating hydraulic oil cylinder about 1 is provided with piston rod, and the piston rod of automatic reciprocating hydraulic oil cylinder 1 both sides is positioned at connecting sleeve 2 inside, and is connected with large plunger 3 and small plunger 5 respectively.
The diameter of left midge room A and right midge room B is greater than the diameter of ball valve 9 inner passage, can store certain slurries.
When automatic reciprocating hydraulic oil cylinder 1 piston rod moves right, left midge room A midge, the plasma discharge of right midge room B (small plunger end), it exports as high pressure, small displacement slurries; When automatic reciprocating hydraulic oil cylinder 1 piston rod is to left movement, the A plasma discharge of left midge room, right midge room B (small plunger end) midge, it exports as low pressure, huge discharge slurries; So move in circles, reach the effect of pulsation plasma discharge.
