The utility model has the advantages of simple structure, and easy fabrication. When the materials distributing rods are used for depositing the concrete in construction, the isolating phenomenon can not be generated from the materials discharging outlets, and the constructing quality of the concrete is improved.
Description
The utility model relates to a kind of building trade concrete device, is specifically related to a kind of boom concrete discharging opening isolation-proof device.
In building trade, during with the boom fluid concrete, its end carrier pipe meeting nature is sagging, and carrier pipe generally reaches three meters, even longer.And when boom armed lever vertically downward during cloth, concrete arrives the carrier pipe exit from the boom peak, and the discrepancy in elevation has more than ten meters.The discrepancy in elevation freely falling body that concrete is from three to ten meters drops to working face, because proportion is different, aggregate in the concrete and cement paste can be serious discrete, produce segregation phenomenon, had a strong impact on quality of concrete, stayed hidden danger to building.
The purpose of this utility model is the defective that overcomes prior art, and a kind of device that produces segregation phenomenon can prevent the boom fluid concrete effectively the time is provided.
The purpose of this utility model is to realize by following technical scheme.It is characterized in that it is made up of valve seat and valve cylinder, described valve seat and elephant trunk join, valve cylinder upper end and valve seat bottom connection.Valve cylinder can be combined into up big and down small back taper by two or two above valve plates, and the upper end links to each other with the valve seat bottom by hinge pin, and a lower end and an end are fixed and can be hinged along the adjusting lever of its axial slip.The adjusting lever appearance is processed with external screw thread, be sheathed on the affixed connecting rod of valve seat on, be provided with the adjusting lever mandrel in it, spring housing thereon; Also be provided with retaining mud cover in the adjusting lever outside.Also can establish an awl tube between valve seat and valve cylinder, a fixed bar is established in the valve cylinder bottom, and guide rod is established the spring that can be regulated by adjusting nut, the sheathed guiding valve of external surface admittedly thereon in it.Automatically control the size of its discharging opening and then the opening degree of control discharging opening produces segregation because of the carrier pipe inner concrete is very few when preventing to pour into a mould by the elephant trunk inner concrete amount of having, thereby realized the purpose of this utility model.
The utility model is simple in structure, makes easily, can be according to the unlatching of the concrete amount of the having automatic regulating valve tube discharging opening in the carrier pipe of boom end, when the concrete amount of having in the carrier pipe does not reach setting value, and the valve cylinder discharging opening can be closed automatically; And when surpassing setting value, concrete can continuously flow out into strips, uses when the boom fluid concrete of this device is housed during construction, and concrete can not produce segregation phenomenon, and concrete construction quality is improved.

The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
Embodiment one: as shown in Figure 1, the utility model is by valve seat 1, and valve cylinder 3 is formed, and valve seat 1 upper end links to each other with boom end elephant trunk 11 by pipe clamp 17, and bottom and valve cylinder 3 upper ends join.Valve cylinder 3 is the up big and down small back tapers that are combined into by the valve plate more than two or two, and the bottom is a discharging opening, and its valve plate has certain elasticity, when concrete has certain weight, valve plate is strutted, and discharging opening increases, and concrete can continuously flow out; When the concrete amount of having is not enough in the carrier pipe, be trapped in the carrier pipe owing to discharging opening is less.
Embodiment two: as shown in Figure 2, present embodiment also is by valve seat 1, valve cylinder 3 is formed, valve seat 1 upper end links to each other with boom end elephant trunk 11 by pipe clamp 17, hinge pin 2 is established in the bottom, and also by two or two up big and down small back tapers that above valve plate is formed, upper end and valve seat 1 join valve cylinder 3, link to each other with valve seat 1 bottom by hinge pin 2, each valve plate can rotate around hinge pin 2; On valve seat 1, fix a connecting rod 7, these connecting rod 7 other ends are established adjusting lever 6, its axle center is vertical with valve seat 1 axle center, and external surface is processed with screw thread, is sheathed in the internal thread hole that connecting rod 7 end correspondences offer, offer a through hole in the adjusting lever 6, adjusting lever mandrel 8 one ends are placed in it, can make axial slip within it, and the other end is hinged with the free bearing 10 that is located at valve cylinder 3 bottoms by hinge pin 9.On adjusting lever mandrel 8, also be arranged with a spring 5, because the effect of spring force can make valve cylinder 3 discharging openings less.Also be provided with retaining mud cover 4 in adjusting lever 6 outsides, prevent that concrete from falling in it and damage moving component.Adjusting lever 6 adopts thread connecting mode with connecting rod 7, and during rotation adjusting lever 6, the pretightning force of adjustable springs 5 is to regulate the setting value of the valve cylinder 3 inner concrete amounts of having.When being full of a certain amount of concrete in the elephant trunk 11.Its deadweight can overcome spring force makes valve cylinder 3 discharging openings open very greatly; And when the concrete amount of having in the carrier pipe does not reach setting value, the effect of spring 5 makes valve cylinder 3 discharging openings very little, concrete produces and is detained, thereby reached the purpose of the accurate control boom carrier pipe concrete amount of having, the generation of concrete segregation phenomenon when having prevented the boom fluid concrete effectively.
Embodiment three: as shown in Figure 3, present embodiment is established an awl tube 12 between valve seat 1 and valve cylinder 3, the three is welded to each other, establish a fixed bar 13 in the bottom of valve cylinder 3, guide rod 14 is fixed on central authorities, processing one through hole in it, the end of through hole is processed with internal thread, adjusting nut 15 is threaded onto in it, and spring 5 places in the through hole of guide rod 14, can regulate its pretightning force by adjusting nut 15; At guide rod 14 external surfaces, an also sheathed guiding valve 16 can be made axial slip along guide rod 14, and during its free state, the top can be stretched in the valve seat 1, forms annular discharging opening with valve seat 1.When being full of a certain amount of concrete in the boom end elephant trunk 11, the spring force that its deadweight can overcome spring 5 moves down guiding valve 16, lifts off a seat and 1 enter in the valve cylinder 3 in the top, and discharging opening is increased, and the concrete discharging is very smooth; And when the concrete amount of having in the carrier pipe did not reach setting value, the effect of spring 5 was stretched in the valve seat 1 guiding valve 16, forms a less annulus, and concrete is stranded in the valve cylinder 3.
