The specific embodiment
Be elaborated below in conjunction with the accompanying drawing specific embodiments of the invention.Should be understood that the specific embodiment described herein only is used for explanation and explains the present invention, is not limited to the present invention.
As shown in Figure 1; The mounting structure of a kind of concrete pumping unit provided by the present invention; Wherein, The concrete pumping unit comprises: pair of hydraulic cylinders 100, with this a pair of concrete cylinder 200 that hydraulic cylinder 100 is connected and the hopper 300 that is positioned at the discharge end of said a pair of concrete cylinder 200; Said mounting structure comprises the frame 400 that is used to install said concrete pumping unit, and wherein, the set-up mode of said concrete pumping unit raises for the discharge end from said pair of hydraulic cylinders 100 to said a pair of concrete cylinder 200 gradually.Here " height " with (concrete pump truck) concrete pumping unit in working order the time with respect to the orientation on ground.
The concrete pumping unit can be the hydraulic piston type twin-tub concrete pump that generally adopts.The form of structure of this kind hydraulic piston type twin-tub concrete pump and operating principle can with reference in " engineering machinery " (Li Qiyue chief editor, publishing house of Central South University, the 1st edition the 5th printing October in 2009) the 9th chapter about the description of concrete pump.
In technical scheme of the present invention; Mainly be that arrangement and/or mounting structure to the concrete pumping unit improves; Therefore will be simple or omit description to concrete pumping unit itself, but describe emphatically and the arrangement and/or the mounting structure technical characterictic in close relations of concrete pumping unit.
Utilize technical scheme of the present invention; Because the set-up mode of said concrete pumping unit on frame is: the discharge end from said pair of hydraulic cylinders to said a pair of concrete cylinder raises gradually; Therefore when the concrete materials in the hopper when hopper gets into the concrete cylinder of correspondence; Both can receive the effect of the suction of this concrete cylinder; The potential energy of the self gravitation that can also utilize above-mentioned set-up mode and bring gets in the corresponding concrete cylinder thereby more help concrete, and then has improved the suction efficiency when concrete gets into the concrete cylinder.
Usually, pair of hydraulic cylinders respectively with the coaxial setting of a pair of concrete cylinder, therefore, a hydraulic cylinder has identical central axis with a corresponding concrete cylinder, another hydraulic cylinder has identical central axis with another concrete cylinder, these two central axis are parallel.Thereby the central axis of a pair of concrete cylinder 200 forms a plane M, and is as shown in Figure 1.
Because the set-up mode of concrete pumping of the present invention unit; As shown in Figure 1; The longitudinal direction S of formed plane M of the central axis of said a pair of concrete cylinder 200 and said frame 400 (usually; Under the state of accomplish installing, the longitudinal direction S of frame 400 is parallel with horizontal direction) between angle be that 2 degree are to 45 degree, with the compliance of the running parameter that is adapted to different working conditions requirement and concrete pumping unit self.

Through water tank 500 being fixedly installed in different installation site in a plurality of installation sites on the installing plate 402, can make the concrete pumping unit have different relative positions with respect to frame 400.Can install in several ways between installing plate 402 and the water tank 500, as passing through modes such as bolt, pin connection.
When the concrete pumping unit carries out operation; Noise is all relatively large with vibration, thereby in order to reduce the vibratory impulse of concrete pumping unit, thereby reduce noise and protect the concrete pumping unit; Especially cushion along reciprocating impact on the concrete pumping unit longitudinal direction; Preferably, the plane N at said installing plate 402 places and angle β between the formed plane M of central axis of said a pair of concrete cylinder 200 65 spend to 85 and spend, and be as shown in Figure 1.
Spend to 85 and spend through the angle β between the formed plane M of central axis of the plane N at installing plate 402 place and said a pair of concrete cylinder 200 being designed to 65; Thereby make above-mentioned installing plate 402 can be adapted to the requirement of the installation position of concrete pumping unit on frame 400; Also can resist simultaneously the concrete pumping unit and (for example when pumping, move back and forth the vibration that produced and/or impact along the longitudinal direction; Installing plate 402 can utilize the flexible of self and move (like vibration) with the pumpdown of concrete pumping unit, thereby plays buffering or resist above-mentioned vibration and/or impact).
Further preferably, the angle β between the formed plane M of central axis of the plane N at said installing plate 402 places and said a pair of concrete cylinder 200 70 spends to 80 and spends.
Preferably, flexible preferably for installing plate 402 is had, the thickness of installing plate 402 is thinner relatively, thereby makes installing plate 402 be convenient to realize cushioning effect.
In addition, in order to realize cushioning effect better, said installing plate 402 can be preferably elastic plate.For example, installing plate 402 can be processed by the rubber-like material, can be rubber tile or other rubber-like plastic plates like installing plate 402.Certainly, installing plate 402 also needs to carry the structural strength that the concrete pumping unit acts on the load on the installing plate 402 when having the function of shock absorbing.Select to the concrete structure of installing plate 402 and material, those skilled in the art can be according to concrete operating mode and in addition design alternative.
In addition, preferably, between the water tank 500 of said installing plate 402 and said concrete pumping unit, be provided with buffer pad, can play the effect of shock absorbing too.Buffer pad can be rubber pad or plastic mattress etc.
More than describe the technical characterictic of the mounting structure of concrete pumping provided by the present invention unit in detail.In addition, the present invention also provides a kind of concrete pumping equipment, and this concrete pumping equipment comprises the mounting structure of above-mentioned concrete pumping provided by the present invention unit.
For example; Said concrete pumping equipment can be stationary concrete pump (frame 400 is fixing), Vehicular concrete pump (frame 400 is fixedly mounted on the vehicle frame of pump truck, perhaps directly utilizes the frame 400 of the vehicle frame of pump truck as above-mentioned mounting structure) or concrete pump truck.
More than combine accompanying drawing to describe preferred implementation of the present invention in detail; But; The present invention is not limited to the detail in the above-mentioned embodiment; In technical conceive scope of the present invention, can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
