It is pointed out that two first auxiliary girder portions 111 also can connect 112, two second auxiliary girder portions 112 of the corresponding separately second auxiliary girder portion by corresponding retractor device 17 respectively and connect magazine attachment 12 more respectively, this connection saving in material is convenient to dismounting.
Particularly, retractor device 17 can be telescopic oil cylinder, and the fixed part of telescopic oil cylinder connects the first auxiliary girder portion 111, and pars contractilis connects the second auxiliary girder portion 112.Obviously, the fixed part of telescopic oil cylinder is connected with the second auxiliary girder portion 112 herein, and pars contractilis is connected also with the first auxiliary girder portion 111 to be set up.
The telescopic oil cylinder that hydraulic circuit drives does not have the pivoting friction parts, each parts long service life, and simple in structure, operation, and hydraulic operation campaign easily is steady.
The hydraulic oil source that drives oil circuit can be from the propulsion source of the hydraulic control system of concrete pump truck, and this scheme need not provide extra oil sources, and is simple in structure, and cost is lower.
Particularly, described telescopic oil cylinder can be connected with the second auxiliary girder portion 112 with the first auxiliary girder portion 111 respectively by hinged-support, can be separately positioned on second side of the inwall of the first auxiliary girder portion 111 and the second auxiliary girder portion 112 with the first auxiliary girder portion 111 and the second auxiliary girder portion, 112 bonded assembly hinged-supports.
The hinged-support link ratio is more convenient, and is convenient to dismounting.
Stretching freely of retractor device 17 work for convenience, the pipe arrangement 13 of walking on stage of pumparound can be designed as structure as shown in Figure 1.The pipe arrangement 13 of walking on stage comprises two elbows and the straight tube of pegging graft with two described elbow one ends, straight tube can with two elbow slide relative.When magazine attachment 12 is mobile backward, two elbows and straight tube slide relative, straight tube is placed on the exterior length of two elbows will be increased, the also corresponding growth of the length of the pipe arrangement 13 of promptly walking on stage; When magazine attachment 12 bounced back under the effect of retractor device 17, two elbows and straight tube be slide relative also, and straight tube is placed on the outer length of two elbows also to be shortened relatively, and the contraction in length of the pipe arrangement 13 of promptly walking on stage recovers virgin state.
This simple in structure, flexible freely of pipe arrangement 13 of walking on stage can guarantee the reliability of pump concrete work again.
In order to make concrete pump truck when construction, the center of gravity of car load further moves backward, and the get on the bus mounting means of other counterweights of portion of concrete pump truck can be set further, moves after the center of gravity when making concrete pump truck work.
Usually, pumparound also comprises water tank 14, and water tank 14 is connected on the auxiliary girder 11 by water tank bearing 141, concrete pump truck is when pump concrete, need be in water tank 14 fills with water, therefore, the working weight of water tank 14 also is one of very important main weight of concrete pump truck upper frame part.
In a kind of specific embodiment, the guiding parts 16 of water tank bearing 141 can be set on the auxiliary girder 11, guiding parts 16 is provided with opening upwards and the slideway that extends along the bodywork length direction, slideway comprise two sidewalls and with two sidewall bonded assembly diapires, and diapire is connected with the roof of the first auxiliary girder portion 111, guiding parts 16 and being connected of auxiliary girder 11 can be that fixed type connects, and welding manner for example is on the end face that is welded on the first auxiliary girder portion 111 with guiding parts 16; Also can be movable connection, for example bolt connecting mode can offer some first through holes that match with the mounting hole of water tank bearing 141 on the diapire, and the distance between adjacent first through hole can be determined according to actual conditions.
Water tank bearing 141 is plugged in the slideway of guiding parts 16, water tank bearing 141 can be along groove slide relative optionally, water tank bearing 141 can be by being bolted in the first auxiliary girder portion 111, for example, adjust the position of first through hole of guiding parts 16, make the spacing of mounting hole on its pitch of holes and the water tank bearing 141 suitable, water tank bearing 141, guiding parts 16 and the first auxiliary girder portion 111 are fixed together with bolt.Certainly, the fixed form between the three is not limited to foregoing description, also can select fixed form in twos, for example earlier guiding parts 16 is fixed in the first auxiliary girder portion 111, water tank 14 bearings is fixed on the guiding parts 16 again.
Before the concrete pump truck construction, water tank bearing 141 is moved to the rear of bodywork length along groove, fixedly water tank bearing 141 fills water to water tank 14 on auxiliary girder 11 then, and the center of gravity of car load also will move accordingly backward this moment; When concrete pump truck stops pumping and is converted to travelling position, water tank bearing 141 is moved to the place ahead of bodywork length along groove, and fixedly water tank bearing 141 is on auxiliary girder 11, and the center of gravity of car load also will move forward accordingly this moment, return to the initial position, do not increase the rear overhang value of concrete pump truck.
Center of gravity when the mounting means of above-mentioned water tank is worked concrete pump truck further moves backward, has increased the stability of car load work, and the structure of guiding parts 16 helps water tank 14 along auxiliary girder 11 length direction easy motions, and operation, laborsaving easily.
Except above-mentioned pumparound, the utility model also provides a kind of concrete pump truck that comprises above-mentioned pumparound, because above-mentioned pumparound has above-mentioned technique effect, the concrete pump truck with above-mentioned pumparound also should have the corresponding techniques effect.The structure of above-mentioned other each several parts of concrete pump truck please refer to prior art, and this paper repeats no more.
More than a kind of concrete pump truck provided by the utility model and pumparound thereof are described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
