Abstract
The utility model relates to a novel auxiliary beam structure of a concrete mixer. The novel auxiliary beam structure comprises two longitudinal beams and a plurality of cross beams which are arranged between the two longitudinal beams. The auxiliary beam structure is characterized by also comprising lining plates and two pulling plate elements, wherein the lining plates are arranged at the inner sides of the longitudinal beams; a part of plate bodies of the lining plates are higher than the upper surfaces of the longitudinal beams; connecting plates are arranged on the upper surfaces of the longitudinal beams; each pulling plate element is composed of two plate bodies which have an included angle greater than 90 degrees; the front plate body of each pulling plate element is clamped between the lining plate and the connecting plate and is fixedly connected through fasteners; and the back plate body of each pulling plate element is fixedly connected with a back platform. Front cross beams of the pulling plate elements are also arranged at the front ends of the pulling plate elements; the two ends of the front cross beams of the pulling plate elements are respectively and fixedly connected with the lining plates at the two sides; and triangular reinforcing plates are arranged at the front and back positions of the front cross beams of the pulling plate elements. Middle rear axle cross beams are also arranged in positions of the longitudinal beams corresponding to the centers of middle rear axles of a chassis. The novel auxiliary beam structure has the advantages of being capable of increasing the bending resistance and torsion resistance performance of an auxiliary beam, reducing the alternating stress generated by the auxiliary beam in the using process of the stirrer and prolonging the service life of the auxiliary beam.
Description
Technical field
The utility model relates to the concrete mixer truck auxiliary girder, specifically be the new-type auxiliary girder structure of a kind of concrete mixer truck.
Background technology
Concrete mixing and transporting car is as the concrete special-purpose vehicle of transportation, and " supported at three point " formula structure is counted in installing on it, and promptly trucd mixer agitator tank tank body front end and reductor are installed on the dress front carriage as the centre of gyration; The tank body rear end is installed on the posterior bracket as rotating fulcrum through a pair of rolling supporting wheel.Since this " supported at three point " formula structure, dress stress extreme difference on the trucd mixer, and the concentrfated load before and after the trucd mixer on the frame needs closely to be connected with chassis ridgepole through auxiliary girder, and load is evenly distributed on the chassis ridgepole.In the vehicle operation running; The trucd mixer chassis ridgepole, on adorn auxiliary girder and all bear very big moment of flexure, moment of torsion; Owing to receive the flexible crossbeam in chassis and auxiliary girder material and effect on structure; On the trucd mixer chassis particularly long at wheelbase, that side's amount is bigger, the trucd mixer auxiliary girder very easily received generation fatigue failure under the effect of alternate stress in the lasted time.
The utility model content
The purpose of the utility model is to be the deficiency that solves the problems of the technologies described above, and provides a kind of concrete mixer truck new-type auxiliary girder structure.
The utility model is the deficiency that solves the problems of the technologies described above, and the technical scheme that is adopted is: the new-type auxiliary girder structure of a kind of concrete mixer truck comprises two longerons and is arranged on many crossbeams between two longerons; It is characterized in that: also comprise liner plate and two arm-tie spares, liner plate is fixedly installed on the longeron inboard, and a part of plate body of liner plate exceeds the longeron upper surface; The longeron upper surface is provided with connecting plate; Arm-tie spare is made up of two sections plate bodys, and two sections plate bodys have the angle greater than 90 °, and the leading portion plate body of arm-tie spare is folded between liner plate and the connecting plate; And through the securing member fixed connection, the back segment plate body of arm-tie spare is fixedly connected with the backstage.
The front end of said arm-tie spare also is provided with arm-tie spare front beam, and the two ends of arm-tie spare front beam are fixedly connected with the liner plate of both sides respectively, and is provided with the triangle stiffener at the front and back position of arm-tie spare front beam.
Back axle crossbeam during the back axle center also is provided with in the corresponding chassis of said longeron.
The utility model can effectively increase bending resistance, the torsional property of auxiliary girder, weakens the alternate stress that auxiliary girder produces in the trucd mixer use, prolongs auxiliary girder service life.
