Abstract
The utility model relates to a split concrete distribution valve. In the structure, a D valve shell is connected with a D valve connection plate through a pin shaft, and the D valve connection plate is assembled together with a turning cylinder; and a hopper is connected with the D valve shell through screws, side faces of the D valve shell and the D valve connection plate are provided with matching holes, two locking cylinders are fixed in the matching holes of the D valve connection plate through screws, and an S pipe is connected with the D valve shell through a shaft sleeve, a sealing component and a standard component, is provided with a spline and is connected with a swinging cylinder through the spline, so that movement of the S pipe can be switched by the swinging cylinder in a reciprocating way to realize pumping switching. Since the split modular design is adopted and the valve is divided into the hopper, a D valve and the S pipe which are arranged independently, no materials can be accumulated in the hopper, the present common problem of material accumulation in the hopper can be solved, wear plates, cutting rings and other easily wearing parts can be replaced more easily, and the operational efficiency can be improved. Due to arrangement of the unique rear-mounted swinging cylinder, a better material suction performance can be achieved, and the pumping efficiency can be significantly improved.
Description
Technical field
The utility model relates to the construction implement field, is specifically related to the concrete valve in the concrete pump truck pumping system, is mainly used in concrete and drags main pumps such as formula pump, the vehicle-mounted pump of concrete, concrete mixer to send in the system.
Background technique
At present, concrete mixer is widely used in the pouring concrete construction operation, during pump concrete; Concrete mixer promotes two concrete piston to-and-fro motion of carrying in the cylinder respectively through two master cylinders; Thereby realize concrete suction and pumping, detailed process is a concrete piston when under the drive of one side master cylinder, bouncing back, and concrete is sucked carry in the cylinder; Simultaneously; Another carries the concrete piston in the cylinder barrel under the drive of pumping master cylinder, to stretch out, and its concrete that in a last roundtrips, sucks is released, and realizes concrete pumping.
In concrete pumping construction, agitator truck is put into the concrete slurry in the hopper of pump truck, and the concrete in the hopper pushes out concrete through carrying cylinder under the to-and-fro motion of master cylinder.At present, at concrete pumping in duty cycle, the following problem of ubiquity: the one, concrete suction property is not good enough, and the 2nd, concrete buildup phenomenon in hopper happens occasionally, and the 3rd, it is inconvenient to change the glasses plate cutting ring.Therefore, how to improve pumping efficiency, glasses plate, cutting ring are changed in efficient quick ground, and cleaning up hill and dale fast that hopper becomes is the technical problem of the required solution of those skilled in the art.
Summary of the invention
The purpose of the utility model is in order to overcome problem and the shortcoming that above-mentioned existing technology exists, and a kind of split type concrete pump distributing valve of easy to use, reliable performance is provided.
Technological scheme through following solves the problems of the technologies described above:
Split type concrete pump distributing valve; Mainly constitute by hopper, D valve connecting plate, D valve chest, S pipe, 1 overturning oil cylinder, 2 locking cylinders, 1 oscillating oil cylinder; The D valve chest is connected through bearing pin with D valve connecting plate, and D valve connecting plate also is assembled together with overturning oil cylinder; D valve casing physical efficiency is opened through the flexible of overturning oil cylinder like this; Hopper links to each other with the D valve chest through screw, and the side of D valve chest and D valve connecting plate all is processed with matching hole, and 2 locking cylinders are passed through screw on the matching hole of D valve connecting plate; The piston rod of locking cylinder stretches out in the matching hole that inserts the D valve chest in the back D valve chest and the locking of D valve connecting plate; S pipe links together with standard piece with the D valve chest through axle sleeve and Sealing, and on the S pipe, is processed with spline, and the S pipe passes through spline and is connected with oscillating oil cylinder; Thereby make oscillating oil cylinder can back and forth switch the motion of S pipe, realize the switching of pumping.
The utility model adopts split type modular design, and distributing valve has been divided into 3 separate parts, i.e. hopper, D valve, S pipe; This split type structure had both guaranteed no buildup in the hopper; Solve present ubiquitous hopper buildup problem, can also change easily damaged partss such as glasses plate, cutting ring more easily, improved operating efficiency; Unique rear-mounted oscillating oil cylinder suction property is better, can significantly improve pumping efficiency.

Fig. 3 faces outline drawing for the oscillating oil cylinder of the utility model
Fig. 4 is the locking cylinder front view of the utility model.
Embodiment
In conjunction with accompanying drawing the utility model is done further to describe.
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; The utility model mainly is made up of 1 overturning oil cylinder 1, hopper 2, S pipe 3, D valve chest 4,6,2 locking cylinders 7 of 5,1 oscillating oil cylinder of D valve connecting plate; D valve chest 4 and D valve connecting plate 5 are connected through bearing pin, and D valve connecting plate 5 also is assembled together with overturning oil cylinder 1; D valve chest 4 can be opened through the flexible of overturning oil cylinder 1 like this; Hopper 2 links to each other with D valve chest 4 through screw, and the side of D valve chest 4 and D valve connecting plate 5 all is processed with matching hole, and 2 locking cylinders 7 are passed through screw on the matching hole of D valve connecting plate 5; The piston rod of 2 locking cylinders 7 stretches out in the matching hole that inserts D valve chest 4 in the back D valve chest 4 and 5 lockings of D valve connecting plate; S pipe 3 links together with D valve chest 4 usefulness standard piece through axle sleeve and Sealing, and on S pipe 3, is processed with spline, and S pipe 3 passes through spline and is connected with oscillating oil cylinder 6; Thereby make oscillating oil cylinder 6 can back and forth switch 3 motions of S pipe, realize the switching of pumping.
This distributing valve is in off position the time; The locking cylinder rodless cavity oil-feed of D valve both sides promotes piston rod movement, thus locking D valve chest and D valve connecting plate; The oil-feed of overturning oil cylinder rodless cavity; Piston rod stretches out, and guarantees that D valve chest and D valve connecting plate fit tightly, and the oscillating oil cylinder to-and-fro motion can drive the swing of S pipe;
During opening state, at first dismantle terminal bend pipe, operate the hopper switch valve group then; Make the locking cylinder rod chamber oil-feed of D valve both sides, promote piston rod movement, thereby separate D valve chest and fitting seat; The oil-feed of overturning oil cylinder rod chamber, the piston rod withdrawal, pulling D valve chest launches several angle.Thereby can change easily damaged partss such as glasses plate, cutting ring with comparalive ease, and can thoroughly clean hopper, guarantee no buildup in the hopper.
