Abstract
The utility model discloses a grouting pump, and particularly relates to a horizontal-type single-cylinder double-plunger synchronous grouting pump which comprises a cylinder and two plungers driven by the cylinder. The two plungers are connected to a piston of the cylinder through a connecting pole and are arranged in parallel along the horizontal direction. A plunger sleeve is sleeved outside each plunger. A grout sucking valve and a grout discharging valve are respectively connected to outer sides of the two plunger sleeves. Due to the fact that the grouting pump is arranged in a single-cylinder double-plunger structure, synchronous movement of the two plungers can be guaranteed, and therefore synchronous grouting and grout discharging of two grouting materials can be guaranteed. When the grouting in the proportion of 1:1 is not needed, only one plunger and seal need replacing, the diameter of the grouting pump is changed, the grouting not in the proportion of 1:1 can be achieved. The two plungers are arranged in parallel along the horizontal direction, a horizontal-type structure is thereby formed, and therefore equipment operation is stable. The grout sucking valve and the grout discharging valve are respectively connected to the outer sides of the two plunger sleeves, the grout sucking valve and the grout discharging valve are externally arranged, the drift diameter is widened, the grouting materials are not easily blocked, and working is reliable and stable.
Description
Technical field
The utility model relates to a kind of grouting pump, specifically a kind of horizontal single cylinder double-plunger tunneling synchronous mud injecting pump.
Background technique
The chemical slip casting material overwhelming majority is single liquid slurry or biliquid slurry, requires synchronously plasma discharge of bi-material or slip casting when annotating the biliquid slurry, could mix in proportion.And can realize that the Pneumatic grouting pump of bi-material synchronous grouting mostly is vertical three plunger Pneumatic grouting pumps or two cylinder single plunger Pneumatic grouting pump on the market now.But they have respectively following shortcoming:
1, vertical three plunger Pneumatic grouting pumps only use two plungers under most of working condition, and the another plunger also is forced to work simultaneously, and plunger is lubricated without slurries, so plunger seal easily damages.Owing to being set to vertical structure, suction slurry valve ball is built in the plunger simultaneously, and the latus rectum structure is less, and very granule or impurity just easily stop up valve ball or valve seat, cause the pneumatic slurry casting pump work malfunctioning.
2, two cylinder single plunger Pneumatic grouting pumps use two cover cylinders, in use when annotating two kinds of injecting paste materials in the slip casting of 1:1 ratio, volumetric efficiency can not be identical under different loads for two cover cylinder system, therefore, in use for some time, two cylinders just can not synchronous working, may cause a cylinder doing the midge action, and another cylinder is being done the plasma discharge action.Commonly use ratio when annotating two kinds of injecting paste materials by 1:4() during ratio slip casting, must turn down wherein cylinder intake valve, change air inflow, change speed, thereby change the plasma discharge amount, at this moment because two cylinder strokes are identical, in the situation that speed is different, will cause a cylinder to cover first stroke, no longer plasma discharge, the another cylinder is not but covered stroke, still in plasma discharge, can't accomplish synchronous grouting.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly operates steadily reliable and can guarantee to annotate synchronously horizontal single cylinder double-plunger tunneling synchronous mud injecting pump of plasma discharge.
In order to solve the problems of the technologies described above, horizontal single cylinder double-plunger tunneling synchronous mud injecting pump of the present utility model, comprise a cylinder and by two plungers of this air cylinder driven, two plungers are connected on the piston of cylinder by connecting rod and along continuous straight runs is arranged in parallel, two plungers overlap respectively outward plunger bushing are arranged, and two plunger bushings are circumscribed with respectively pulp absorbing valve and pulp-expelling valve outward.
The joint of described two plunger bushings and two plungers is respectively arranged with seal ring.
After adopting above-mentioned structure, owing to being set to single cylinder double-plunger structure, can guarantee that two plungers are synchronized with the movement, thereby guarantee that two kinds of injecting paste materials annotate plasma discharge synchronously, when not needing in the slip casting of 1:1 ratio, only need to change wherein a plunger and seal ring, change its diameter, can realize the slip casting of non-1:1 ratio; Two plunger along continuous straight runs are arranged in parallel, and the horizontal type structure that forms thus is steady when making the equipment operation, have eliminated the impact of slurries gravity on suction slurry precision; Two plunger bushings are circumscribed with respectively the suction pulp-expelling valve outward, will inhale pulp-expelling valve thus external, and latus rectum strengthens, and injecting paste material is difficult for stopping up reliable and stable work.
