The specific embodiment
Hereinafter will and combine embodiment to specify the utility model with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
Arrow points is the transmission and concrete transmission direction among the figure.
Like Fig. 2, Fig. 3 and shown in Figure 4, according to first embodiment of the utility model, elastic damper 10 comprises periphery connecting portion 11 and elastic block piece 12, and periphery connecting portion 11 is along the periphery setting of elastic block piece 12.Elastic block piece 12 comprises elastic opening 13 expansible and contraction.
In a unshowned embodiment, elastic opening 13 also can be the long trough opening that extends along the radial direction of elastic block piece 12.This long trough opening is at least three, extends to the periphery from the center of elastic block piece 12, makes to be interconnected between the long trough opening, and forms expansible and the hatch frame that shrinks.
Please combine referring to shown in Figure 5; Second embodiment according to the utility model; Elastic damper 10 have with first embodiment in the periphery connecting portion 11 of periphery connecting portion 11 same structures; Its difference is that the elastic opening that is arranged on elastic block piece 12 center positions 13 of the elastic block piece 12 of elastic damper 10 is circular open.
Preferably, circular open and elastic block piece 12 concentric settings, and circular open extends to a side of elastic damper 10 along the axial direction of elastic block piece 12, makes elastic block piece 12 form the little horn mouth shape of inlet large outlets.When mounted, concrete flows into the osculum outflow from bell-mouthed big mouthful.
Please combine referring to Fig. 6 and shown in Figure 7; Embodiment according to the utility model; The cloth jib comprises to be carried straight tube 20, be arranged on the transporting elbow 30 of carrying straight tube 20 ends and connect the pipe clamp 40 of carrying straight tube 20 and transporting elbow 30; Also comprise above-mentioned elastic damper 10; The periphery connecting portion 11 of elastic damper 10 is arranged on the joint gap position of carrying straight tube 20 and transporting elbow 30, thereby the elastic block piece 12 of elastic damper 10 is on the transfer pipeline of carrying between straight tube 20 and the transporting elbow 30.
Please combine referring to shown in Figure 6, the elastic opening 13 of elastic damper 10 is in contraction state.When concrete had just arrived elastic damper 10 positions, concrete pressure can not overcome the resistance of the elastic block piece 12 of elastic damper 10, and 12 pairs of concrete of elastic block piece form and hinder, and make concrete at elastic opening 13 position reductions of speed.
Please combine referring to shown in Figure 7; When concrete pressure acquires a certain degree; Overcome the resistance of the elastic block piece 12 of elastic damper 10, the elastic opening 13 of elastic block piece 12 is opened, and along the mobile direction expansion of concrete; Make concrete successfully continuously through elastic damper 10, elastic damper 10 does not form powerful inhibition to concrete.
According to the embodiment of the utility model, concrete distributing equipment comprises above-mentioned elastic damper 10 and/or cloth jib.
When terminal jib was in horizontal cloth attitude, concrete provided power by pumping equipment, continuous-flow in elephant trunk under pumping promotes.When concrete arrived elastic damper 10 places, owing to stopping of the elastic block piece 12 that receives elastic damper 10, transmission and concrete transmission speed reduced, and formed obstruction at elastic opening 13 places of elastic damper 10.When the pressure of pumping surpasses the inhibition power of elastic block piece 12 of elastic damper 10, will make the elastic opening 13 of elastic damper 10 deform, opening expands outwardly, and concrete passes through.
When terminal jib is in vertical or inclination cloth attitude; Concrete passes through the quick landing of self gravitation to elastic damper 10 places; The elastic block piece 12 of elastic damper 10 makes concrete slowly slow down mobile and the accumulation concrete, after concrete runs up to constant weight, is enough to make the elastic block piece 12 distortion expansions of elastic damper 10; Elastic opening 13 is opened, and concrete continuous is passed through.Through the obstruction decelerating effect of elastic damper 10, both reduce the degree of the terminal bend pipe 30 of concrete impact wear like this, solved the problem of concrete disintegration again.
Can learn that from foregoing description elastic damper comprises periphery connecting portion and the elastic barrier sheet that is arranged in the periphery connecting portion, elastic block piece comprises elastic opening expansible and contraction.Elastic opening makes elastic damper form latus rectum structure expansible and contraction, and when the object power through elastic damper can not overcome the elastic resistance of elastic block piece, elastic block piece can reduce the transporting velocity of object; Object is slowed down at the elastic block piece place; Thereby reduce the percussion of object, after object power surpassed the elastic resistance of elastic block piece, the opening of elastic block piece expanded to the outside; Latus rectum is opened, and object smoothness from elastic opening is passed through.After this elastic damper is applied to elephant trunk; Can play decelerating effect to the concrete gravel of rapid speed; Thereby guarantee together to carry after slurry arrives sandstone; Prevent concrete segregation, also effectively avoid the sandstone excessive velocities that transporting elbow is caused high speed impact and wearing and tearing simultaneously, prolong the application life of transporting elbow.
More than be merely the preferred embodiment of the utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
