Concrete mixer frame

Abstract

The invention provides a concrete mixer frame. The concrete mixer frame comprises two chassis longitudinal beams spaced in parallel. The two chassis longitudinal beams are fixedly connected through multiple cross beams, and each chassis longitudinal beam is overall formed, and comprises a first beam section, a second beam section, a third beam section and a tail beam section which are sequentially arranged from front to back. A front supporting seat is mounted on the tops of the first beam sections of the two chassis longitudinal beams, a rear supporting seat is mounted on the tops of the third beam sections of the two chassis longitudinal beams, and reinforcing rib plates are arranged on the outer side faces of the second beam sections of the two chassis longitudinal beams separately. Each chassis longitudinal beams is of a structure in which a multi-section type and overall forming are combined, thus, the defect that the gravity center is high in the prior art is overcome, the overall height of a mixer can be reduced, potential safety hazards generated in the driving process of the mixer are eliminated, the overall mechanical strength of the frame can be improved, the overall structure is scientific, reasonable, simple and compact, and mounting and using are convenient; and the concrete mixer frame is widely suitable for being matched with the mixer.

Description

technical field [0001] The invention relates to construction machinery equipment, in particular to a frame of a concrete mixer truck. Background technique [0002] Concrete mixer truck is a special truck used to transport construction concrete. Generally, a cylindrical mixing drum is installed on the frame to carry the mixed concrete. Since the mixing drum keeps rotating during transportation, it can ensure that the inside of the mixing drum Concrete will not set. [0003] In the prior art, in order to save freight, the loading capacity of the mixer truck is getting bigger and bigger, which directly leads to the bigger and bigger barrel of the mixing drum, which leads to the higher and higher height of the mixer truck, and after the mixing drum is loaded The high center of gravity causes the center of gravity of the vehicle to be unbalanced, prone to problems such as rollover, and brings serious safety hazards to the driving of the vehicle.
