Abstract
The utility model provides a grouting cylinder, which is composed of a slurry discharge assembly, a cylinder body, a piston rod assembly and a slurry suction assembly. When a piston is driven to move up and down by a piston rod under action of external force, a slurry suction channel and a slurry discharge channel can be opened and closed sequentially to achieve slurry suction and slurry discharge according to generated negative pressure portion and positive pressure portion. The grouting cylinder has the advantages of being compact in structure, convenient to convey in sections, stable in running, fast in sealing speed, high in grouting pressure, capable of sealing tiny leak gaps, and widely applied to grouting of leaks of stratums of mines and tunnels.
Description
Technical field
The utility model relates to the slip casting cylinder in the engineering grouting pump under the high-pressure slip-casting cylinder, particularly coal mine of a kind of mine, tunnel grouting for water blocking and stabilization works.
Background technology
At present, the slip casting cylinder in the grouting pump, it is bulky, uses inconvenience, and tiny leak slit can't be handled, and needs special equipment during carrying; On the other hand, the injecting paste material reaction time is fast, existing slip casting cylinder steadily slip casting effectively in time.
The utility model content
The utility model purpose is to overcome weak point in the prior art, and a kind of simple in structure, esy to use, safe and reliable, grouting pressure is high, cost is low, plugging effect is good slip casting cylinder is provided.But both convenient in carrying again can the slip casting of exactly ground.
The technical scheme that the utility model adopted is: a kind of slip casting cylinder, and comprise plasma discharge combination, cylinder body, piston rod combination, inhale the slurry combination, the plasma discharge combination, inhale slurry combination and cylinder body through being threaded together; Plasma discharge combination front end is provided with gland, dust ring, fairlead and sealing ring, and the rear end is provided with outlet; The piston rod combination is provided with piston rod, pad, piston, piston head, nut, plasma discharge steel ball, is provided with two non-central holes on the piston head side by side, and piston rod is provided with the plasma discharge hole, and the first end of piston is connected with piston rod thread, and an end is connected with nut thread; Inhale slurry combination front end and be provided with resilient key, inhale the slurry steel ball, the rear end is provided with the snap joint of mining U-shaped pin formula.
The beneficial effect of the utility model is: a kind of slip casting cylinder, realized simple in structure, easy to operate, grouting pressure is high, convenient in carrying, the sealing leak is little, shutoff is fast characteristics.
Description of drawings
Accompanying drawing is a kind of slip casting cylinder of the utility model sketch map.
The specific embodiment
Figure of description is the enforcement optimal way of the utility model, inhales step explanation the utility model below in conjunction with accompanying drawing.
As shown in the figure: a kind of slip casting cylinder, comprise plasma discharge combination 1, cylinder body 2, piston rod combination 3, inhale slurry combination 4, plasma discharge combination 1, inhale slurry combination 4 and cylinder body 2 through being threaded together; Plasma discharge is made up 1 front end and is provided with gland 1a, dust ring 1b, fairlead 1c and sealing ring 1d, and the rear end is provided with outlet 1e; Piston rod combination 3 is provided with piston rod 3a, pad 3b, piston 3c, piston head 3d, nut 3e, plasma discharge steel ball 3f; Piston rod 3a is provided with plasma discharge hole 3a '; Be provided with two non-central hole 3d ' on the piston head 3d side by side; Piston head 3d one end is threaded with piston rod 3a, and an end is threaded with nut 3e; Inhale slurry combination 4 front ends and be provided with resilient key 4a, inhale slurry steel ball 4b, the rear end is provided with mining U-shaped pin formula snap joint 4c.
When piston rod 3a drives when moving on the piston 3c under external force, plasma discharge steel ball 3f and nut 3e pathway closure, cylinder body 2 inner carrier 3c form negative pressuren zone to inhaling between slurry steel ball 4b, inhale slurry steel ball 4b and pop up, and inhale the slurry passage and open, and slurries are sucked; When piston rod 3a drive piston 3c moves down; Cylinder body 2 inner carrier 3c form zone of positive pressure to inhaling between slurry steel ball 4b; Inhale slurry steel ball 4b and close suction slurry passage; Plasma discharge steel ball 3f and nut 3e passage are opened, and go up plasma discharge hole 3a ' through the non-central hole 3d ' of piston head 3d, piston rod 3a and are discharged to piston 3c upper end, through plasma discharge mouth 1e plasma discharge.Through the reciprocating motion of piston, realize the suction action of slurries.
