Embodiment Construction

[0016] Referring to the attached drawings, the sub-frame of a large volume concrete mixer truck of the present invention will be described in detail below.

[0017] Such as figure 1 , figure 2 , image 3 As shown, the subframe of a large-scale concrete mixer truck of the present invention includes a subframe 1, a front desk 2, a backstage 3, a brace 4, a U-shaped curved plate 5 and a brace 6. The subframe Beam 1 is located at the bottom of the entire sub-frame and is placed on the chassis 8 of the mixer truck. The sub-beam 1 is mainly composed of two square tubes as the skeleton and the connection between the two square tubes; the front desk 2 is arranged on the sub-frame. One end above the beam 1, the backstage 3 is arranged at the other end above the subbeam 1, the U-shaped curved plate 5 is arranged on the subbeam, and a diagonal brace is arranged between the U-shaped curved plate and the backstage, A "herringbone"-shaped diagonal brace 6 is arranged between the sub-bea...

Abstract

The invention discloses an improved auxiliary frame of a large-earthwork concrete mixing carrier. The auxiliary frame mainly solves the problems that loads of the mixing carrier increase substantially and a prior auxiliary frame cracks easily. The improved auxiliary frame comprises an auxiliary beam, a front table, a rear table, an inclined tensioned support, a U-shaped bent plate and an inclined support, wherein the front table is arranged at one end above the auxiliary beam, the rear table is arranged at the other end above the auxiliary beam, the U-shaped bent plate is arranged on the auxiliary beam, the inclined tensioned support is arranged between the U-shaped bent plate and the rear table, and the inclined support is arranged between an auxiliary beam cross support at the front end of the bottom of the rear table and the U-shaped bent plate. The strength of the auxiliary frame of the concrete mixing carrier can be well improved, the improved auxiliary frame can be used under all kinds of large-earthwork concrete mixing carrier using conditions, local tension resistance of the auxiliary frame of the concrete mixing carrier is improved, and stress conditions of the auxiliary frame are fully optimized.

Description

technical field [0001] The invention relates to an auxiliary frame, in particular to an auxiliary frame of a large-volume concrete mixer truck. Background technique [0002] At present, the domestic commercial concrete industry continues to be hot, and the volume of mixer trucks, which is an indispensable part of concrete transportation, is also increasing, that is, the load of mixer trucks is also increasing. Therefore, the mixer truck has higher and higher requirements on the strength of the sub-frame, and most of the domestic concrete mixer truck manufacturers only increase the materials used on the basis of the original structure to strengthen the strength of the entire sub-frame, but this This method does not solve the problem very well. Due to the substantial increase in the load of the mixer truck, the parts that are prone to breakage of the subframe are mainly the front end of the cable stay and the rear end of the front desk, which not only seriously affects the sa...
