Embodiment
Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
As shown in Figures 2 to 4, according to embodiments of the invention, pumping mechanism comprises hopper 20 and multiple independently pumping unit 10, and pumping unit 10 is connected on hopper 20, suction in hopper 20, and is pumped by the material of suction.Each pumping unit 10 includes pumping water tank 11, concrete cylinder 12, pumping cylinder 13 and distributing valve 15.Separate between the pumping water tank 11 of each pumping unit 10, be an independent individuality separately, mutual noninterference in pumping procedure.The concrete cylinder 12 of each pumping unit 10 is all fixedly installed between hopper 20 and the pumping water tank 11 corresponding to this concrete cylinder 12.The piston rod of pumping cylinder 13 is located in corresponding pumping water tank 11, and the first end of each pumping cylinder 13 is provided with piston 14, and piston 14 is slidably disposed in corresponding concrete cylinder 12.Distributing valve 15 is arranged on the outlet of concrete cylinder 12, enters concrete cylinder 12 for a point batching body or pumps concrete cylinder 12.
Compared with prior art, the present invention is very low to the required precision on concrete cylinder 12 length direction, even if the length of two concrete cylinders 12 has certain deviation, because multiple pumping water tank 11 is no longer an entirety, therefore in the process of a pumping unit 10 pumping, the concrete cylinder 12 of another one pumping unit 10 and the impact of pumping water tank 11 can not be subject to, the radial direction of concrete cylinder 12 does not stress, certainly also just buckling phenomenon can not be produced, therefore the present invention significantly can reduce the required precision of concrete cylinder 12 length direction, free tolerance can satisfy the demands, reduce difficulty of processing and the manufacture cost of concrete cylinder 12.
Pumping mechanism is in pumping or suction process, can not interact between each pumping unit 10, in the process of work, only tension and compression axial deformation can be there is between each parts of each pumping unit 10 self, mutually can not interfere and produce lateral bending distortion, even if therefore improve pumping pressure, also buckling phenomenon can not be produced, still the straightness accuracy of pumping cylinder 13, concrete cylinder 12 and piston rod can be kept well, avoid pumping mechanism to cause eccentric wear because of Cyclic flexion to pumping cylinder 13, piston 14 and concrete cylinder 12, extend the working life of pumping mechanism.
Due to relatively independent between each pumping unit 10, therefore the assembly relation ensured between each parts of single pumping unit 10 is only needed, without the need to regulating the parallelism between pumping water tank 11 and hopper mounting plane specially, as long as add the parallelism ensureing concrete cylinder 12 both ends of the surface man-hour, therefore drastically reduce the area installation difficulty and the installation workload of each parts of pumping unit 10, only need ensure that the machining accuracy of part just can ensure the assembly precision of pumping unit 10 naturally simultaneously, can effectively ensure pumping cylinder 13, piston rod, straightness accuracy between the central axis of concrete cylinder 12, be conducive to the pumping realizing more high pressure.
Preferably, be communicated with by connecting tube 16 between pumping water tank 11.More preferably, connecting tube 16 is flexible pipe.Be flexible coupling by flexible pipe or alternate manner between pumping water tank 11, make to realize intercommunication between pumping water tank 11, both can ensure between two groups of pumping units 10 relatively independent, the water intercommunication in pumping water tank 11 can be ensured again, and the phenomenon that in pumping water tank 11, the water surface sharply rises or declines can not occur in pumping procedure.If the water in two water tanks does not have intercommunication, in suction side, due to the rollback of piston 14, the water in this side concrete cylinder will pour in this side water tank, causes the water tank water surface sharply to rise; In stock side, because the pumping of piston 14 is advanced, the water in this side water tank will pour in this side concrete cylinder, causes the water tank water surface sharply to decline.By two water tanks flexible pipe UNICOM, then the water increased in the water tank of suction side can flow into the water tank adding to pumping side discharge reduction, keeps two Water in Water Tanks positions to stablize; Flexible pipe can also keep two water tanks separate simultaneously.
Preferably, the central axis of each concrete cylinder 12 is parallel to each other, can installation between convenient each pumping unit 10 and cooperation, ensures the smoothness of pumping mechanism work, realizes the smooth and easy pumping of the material bodies to be pumped such as concrete, improve pumping efficiency, save energy consumption.
Above-mentioned each distributing valve 15 can be S pipe valve, C valve, skirt valve or gate valve, also can be other distributing valve.
In conjunction with see shown in Fig. 2 and Fig. 3, according to the first embodiment of the present invention, pumping mechanism is twin-tub pumping mechanism, comprises two parallel pumping unit 10, two pumping units 10 arranged and is connected on same hopper 20.Be connected by many pull bars 30 between pumping water tank 11 with hopper 20, many pull bars 30 form spacing space, and concrete cylinder 12 is arranged in spacing space, and concrete cylinder 12 is pressed between pumping water tank 11 and hopper 20 by pull bar 30.The first end of pull bar 30 extends along the direction away from hopper 20, and is located in pumping water tank 11.Preferably, the part that pull bar 30 first end stretches out pumping water tank 11 is provided with screw thread, screw thread is provided with locking nut 31, locking nut 31 can compress the degree of concrete cylinder 12 by regulating tie bar 30, and regulate the distance between pumping water tank 11 and hopper 20 to a certain extent, therefore can ensure the degree of adaptability between two pumping units 10.Second end of pull bar 30 can be welded on hopper 20, and the mode such as also can be bolted is fixedly connected on hopper 20.In order to prevent in the process of pumping unit 10 pumping, locking nut 31 occurs to loosen, and the pull bar 30 outside locking nut 31 is also provided with lock nut.
Preferably, many pull bars 30 are uniformly distributed along the circumference of concrete cylinder 12, and are fitted on the periphery wall of concrete cylinder 12, and concrete cylinder 12 can be limited within a limited scope by this kind of structure, prevent concrete cylinder 12 from radial motion occurring, ensure stability during pumping mechanism work.
In conjunction with shown in Figure 4, according to a second embodiment of the present invention, it is substantially identical with the first embodiment, difference is, in the present embodiment, concrete cylinder 12 is not fixedly installed between pumping water tank 11 and hopper 20 by pull bar 30, and the two ends of the concrete cylinder 12 of the present embodiment are fixedly connected on hopper 20 and pumping water tank 11 respectively by adpting flange 40, thus the structure that forms a fixed connection.This kind of linkage structure mounting or dismounting are convenient, and can change parts easily, and the manufacturing cost of adpting flange 40 is also comparatively cheap, therefore, it is possible to reduce the cost of pumping mechanism.
In other embodiments, concrete cylinder 12 can also be connected between hopper 20 and pumping water tank 11 by alternate manner, and realize the pumping of material body, the two ends of such as concrete cylinder 12 can be welded on hopper 20 and pumping water tank 11 respectively.
According to embodiments of the invention, pumping equipment comprises pumping mechanism, and this pumping mechanism is above-mentioned pumping mechanism.Preferably, this pumping equipment is concrete pumping equipment, such as concrete pump etc.
