Description
Technical field
Patent of the present invention relates to the concrete work mechanical field, is specially the concrete mechanical device of the long distances of a kind of relay-type.
Background technology
At present, the transmission and concrete transmission system that uses on the ground in the construction work field is mainly by concrete pumping system and the combination of cloth system two parts.Concrete pumping system utilizes the high power hydraulic cylinder to promote concrete transmitting power is provided.During the length distances, the friction between concrete and the cloth tube causes difficulty of transportation, and the loss lot of energy, and transfer efficiency is low; During the conveying circuit turnover, concrete makes cloth system produce violent oscillatory motion to the percussion of S pipe, has reduced transfer efficiency.The opposing party's face length mainly is to utilize pumping vehicle arm rack or tower material distributing machine to realize Construction Arrangement apart from cloth system, and the rigidity jib is inappropriate for work under complex working condition.
The patent of invention content
For the concrete conveying of more flexible realization, the present invention proposes the long distances concrete of a kind of relay-type device, it adopts following technical scheme.
The long distances concrete of relay-type device, its by a plurality of power joints 301 with flexibly connect bucket 302 and alternately be composed in series; Power joint 301 flexibly connects the power joint at bucket 302 connection two ends for transmission and concrete transmission provides propelling movement power, plays the effect of transmission and concrete transmission passage and power buffering;
Said power joint 301 is made up of with the power cylinder I201 and the power cylinder II203 that are positioned at barrel both sides that are rigidly connected the bucket 202 that is rigidly connected;
The bucket 202 that is rigidly connected is the rigidity barrel-like structure of hollow with power cylinder I201, and the part of its hollow is transmission and concrete transmission chamber 110; Inside wall is provided with the check valve sheet 107 of blocking-up transmission and concrete transmission in the transmission and concrete transmission chamber 110 of power cylinder I201; One side of check valve sheet 107 links to each other through hinge 108 with the slide block that places the power cylinder interior 106; Slide block 106 can be along the endwisely slipping of power cylinder I201, and in the slide block movement process, check valve sheet 107 is opened by its stressed difference or be closed: when the side that hinge 108 is installed is under pressure; Check valve sheet 107 closures; When being under pressure away from hinge 108 installation sides, check valve sheet 107 is to the sideway swivel that hinge is installed, and check valve sheet 107 is opened; The two ends of power cylinder I201 are fixed with fixed pulley 105, and said slide block 106 links to each other with piston in the hydraulic oil cavity 102 through the fixed pulley 105 at two ends through wirerope 104; The end face of the power cylinder I201 of the both sides of hydraulic oil cavity 102 inner carriers 103 is respectively A side end face (111) and B side end face 112, wherein near hinge 108 installation sides be the A side end face, away from hinge 108 installation sides is the B side end face; Be respectively arranged with hydraulic oil path A100 and hydraulic oil path B200 that the hydraulic oil of the hydraulic oil cavity 102 of the both sides that are used for piston 103 gets into and flows out in A side end face and B side end face; Piston 103 places hydraulic oil cavity 102; Hydraulic oil in the hydraulic oil cavity 102 promotes piston 103 and moves along hydraulic oil cavity 102; Driving slide block 106 moves in opposite directions;
In power cylinder I201; When hydraulic oil gets into hydraulic oil cavity 102 by hydraulic oil path A (100) high pressure of A side end face 111; Piston 103 is moved to B side end face 112 directions by A side end face 111; Moved to B side end face 112 directions by A side end face 111 thereby drive wirerope 104, wirerope 104 drives slide blocks 106 through fixed pulley 105 and is moved to A side end face 111 directions by B side end face 112, receives the pressure effect near transmission and concrete transmission chamber 110 inner concretes of A side end face 111; This moment, check valve sheet 107 was in closed condition, promoted concrete and was moved to A side end face 111 by B side end face 112; When hydraulic oil gets into hydraulic oil cavity 102 by the hydraulic oil path B200 high pressure of B side end face 112; Piston 103 is moved to A side end face 111 by B side end face 112; Thereby driving wirerope 104 is moved to A side end face 111 by B side end face 112; Wirerope 104 drives slide block 106 through fixed pulley 105 and is moved to B side end face 112 by A side end face 111; Receive the effect near the transmission and concrete transmission chamber 110 inner concrete pressure of B side end face 112, check valve sheet 107 is in open mode, and check valve sheet 107 does not provide power for concrete; Check valve sheet 107 is moved to B side end face 112 by A side end face 111 along casing wall, and 111 motions provide SBR to the A side end face by B side end face 112 in order to promote concrete next time;
Said power cylinder I201 joins end to end when being connected through the bucket 202 that is rigidly connected with power cylinder II203, and promptly the B side end face 112 of power cylinder I201 links to each other with the A side end face 111 of power cylinder II203.
In power joint 301; When the check valve sheet among the power cylinder I201 107 when A side end face 111 ends promote the concrete motion; The check valve sheet 107 of power cylinder II203 is to 112 end motions of B side end face; The concrete path in the transmission and concrete transmission chamber 110 in this moment power cylinder II203 is open, by the concrete thrust in pull of vacuum and 112 outsides, B side end face, 112 outsides, power cylinder II203B side end face concrete get into power cylinder II203 and be rigidly connected in barrels 202; When the check valve sheet 107 of power cylinder I201 moved to A side end face 111, the check valve sheet 107 of power cylinder II203 moved to B side end face 112; After this; The check valve sheet 107 of power cylinder I201 to 112 motions of B side end face also in opened condition; The concrete path of power cylinder I201 is open state, and the check valve sheet of power cylinder II203 107 is closed and to 111 motions of A side end face, promotes the concrete power cylinder I201 that moves upward and alternately for the interior concrete of passage power is provided with power cylinder II203; Make concrete in transmission and concrete transmission chamber 110, move to A side end face 111, move to power cylinder II203 by power cylinder I201 by B side end face 112.
The described bucket 302 that flexibly connects adopts elastomeric material to process, and has bellows structure, has lateral bending and transverse compression ability.
The beneficial effect of the long distances concrete of relay-type device is; It is shorter that each joint power joint promotes concrete distance; Thereby only need less power, less power demand and oil cylinder lightweight can realize the high frequency motion of oil cylinder piston, thereby realize concrete high speed conveying.Concrete is to utilize the method for relay-type progressively in passage, to carry forward, does not pile up so concrete can not produce close knot in transfer passage, can reduce the friction of concrete and channel side wall thus, reduces friction energy loss.Whole length can realize flexible the turning apart from the cloth passage, therefore can adapt to the sensible operating mode construction demand of complicated shape cloth, and avoid because the cloth system vibration that the cloth channel corner is brought.
