Description
Technical field
The present invention relates to technical field of engineering machinery, particularly relate to the hydraulic oil container of concrete mixer.The invention still further relates to the concrete mixer that is provided with described hydraulic oil container.
Background technique
Concrete mixer is a kind of being used for the engineering machinery of transmission and concrete transmission to specified position mainly to be made up of hopper, pumping system, hydraulic system, purging system, electrical system, walking chassis etc.
Swinging base is to be used to support swirl gear in the walking chassis and to connect the mechanical structure of getting on or off the bus, can bear the service weight and the vibrations of the jib of getting on the bus, the fundamental function of the hydraulic oil container of hydraulic system is the working liquid body of stores hydraulic pressure system necessity, has functions such as the water of sneaking in heat radiation, precipitated impurities, the separating liquid, gas simultaneously concurrently.
Please refer to Fig. 1, Fig. 1 is the structural representation of first kind of hydraulic oil container of existing concrete pump truck.
As shown in the figure, this kind hydraulic oil container mostly forms hydraulic oil container 2 by the inside box-shaped spatial structure in the Swinging base 1, and its disadvantage is:
At first, the weld seam of hydraulic oil container 2 mostly is the internal weld seams of Swinging base 1, is welded the restriction in space, be difficult to effectively guarantee weldquality during fabrication, and the weld seam detection difficulty is bigger, under baroque situation, even can't finish the experiments of sealing performance of hydraulic oil container 2.
Secondly, Swinging base 1 is as the key stressed member of concrete mixer, and its inner weld seam that constitutes hydraulic oil container 2 also is the stressed weld seam of work.Because frequent vibration can make the weld seam of hydraulic oil container 2 produce fatigue crack when complete machine used, therefore, be difficult to guarantee the fuel tank sealing, the problem that has seepage and be difficult to repair, and then have a strong impact on the working life of whole Swinging base 1 and the safety reliability of complete machine.
Moreover, because the physical dimension of Swinging base 1 is bigger, when handling, the acid washing phosphorization that carries out hydraulic oil container 2 is difficult to effectively be cleared up, can not thoroughly become rusty and improve the quality of hydraulic oil container 2 internal surfaces hydraulic oil container 2.
The existence of above-mentioned these problems directly influences the turbidity test and the sealability of hydraulic oil container 2.
Please refer to Fig. 2, Fig. 2 is the structural representation of second kind of hydraulic oil container of existing concrete pump truck.
As shown in the figure, this kind hydraulic oil container 2 ' be placed on Swinging base 1 ' both sides, and with Swinging base 1 ' integrally welded.Though this structure reduced to a certain extent hydraulic oil container 2 ' internal weld seams, the problem that still exists weld seam to be difficult to detect, also be difficult to simultaneously to guarantee to constitute hydraulic oil container 2 ' the sealability of weld seam, have a problem that is difficult to repair after the seepage.
In addition because hydraulic oil container 2 ' be placed on Swinging base 1 ' the outside, it is bigger to take up room, and is not easy to complete machine and arranges, can't be applicable to all vehicles.
Therefore, how improving the turbidity test and the leakage performance of hydraulic oil container in the concrete mixer Swinging base, is the present technical issues that need to address of those skilled in the art.
