Description

Concrete mixing transport tanker

technical field

The utility model relates to a concrete mixing transport tank truck, in particular to a chassis girder reinforcement structure of a concrete mixing transport tank truck.

Background technique

According to the structural characteristics of the concrete mixing and transporting tank truck, the upper part of the mixing drum and other parts of the chassis and the transported cargo (concrete) are concentrated loads, and the loads are respectively located at the front frame where the reducer is installed and where the supporting wheel is installed to support the mixing drum. At the rear frame, the rear frame of the concrete mixing transport tank truck is located above the rear suspension of the chassis. After loading concrete, since the rear suspension part of the chassis girder is in a cantilever state, it is easy to cause The deformation and sinking of the rear suspension of the chassis girder will cause damage to the chassis and the rear frame. When the vehicle travels on uneven roads, the rear frame will be twisted due to the high force point of the cargo on the rear frame. The deformation is large, and at the same time, the twisting deformation is transmitted to the chassis frame through the connection mechanism between the bodywork and the bottom chassis, thereby causing damage to the chassis frame.

Utility model content

An object of the present utility model is to provide a concrete mixing transport tank truck, which increases the deformation resistance of the chassis girder at the rear frame by setting a cable-stayed beam between the rear frame and the sub-frame longitudinal beam.

Another object of the present utility model is to provide a concrete mixing transport tank truck, which further increases the deformation resistance of the chassis girder at the rear frame by setting an X-shaped scissor beam on the inner side of the two chassis girders.

In order to achieve the above purpose, the utility model provides a concrete mixing transport tank truck, which includes a sub-frame and a front frame and a rear frame respectively fixed on the front and rear ends of the sub-frame for supporting the tank body. The subframe includes two subframe longitudinal beams, a rear frame front crossbeam and a rear frame rear crossbeam located below the rear frame, and it is characterized in that the rear frame and the two subframes A cable-stayed beam is respectively fixedly connected between the frame longitudinal beams, and a reinforcing beam located in front of the centerline of the double bridge of the concrete mixing transport tank truck is arranged between the two sub-frame longitudinal beams. An X-shaped scissor beam located inside the two auxiliary frame longitudinal beams is fixed between the front beams of the rear frame.

Compared with the prior art, the utility model has the advantages and beneficial effects as follows: by pulling the cable-stayed beam between the rear frame and the sub-frame longitudinal beam and setting the scissors beam inside the two sub-frame longitudinal beams, the loading When concrete is applied, the force on the rear frame is transferred to the centerline of the double bridge, thereby effectively reducing the force of the rear frame on the rear suspension of the girder. At the same time, the twisting deformation is reduced due to the increase of the anti-torsion ability of the body itself. amount, to achieve the purpose of reducing the distortion of the chassis beam.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Fig. 1, Fig. 2 and Fig. 6, the concrete mixing transport tank truck of the present invention includes a subframe and a rear frame 2 and a front frame fixed on the front and rear ends of the subframe for supporting the tank body 7. The subframe includes two subframe longitudinal beams 1 , a rear frame front beam 12 and a rear frame rear beam 13 located below the rear frame 2 .

Two cable-stayed beams 3 are respectively fixedly connected between the rear frame 2 and the two auxiliary frame longitudinal beams 1 .

As shown in Figures 1 and 2, one end of each cable-stayed beam 3 is fixed to the inner side of the sub-frame longitudinal beam 1 through the sub-frame longitudinal beam connecting plate 31, and the other end is fixed to the rear frame 2 through a connecting bracket 32. .

The sub-frame longitudinal beam connecting plate 31 extends longitudinally along the sub-frame longitudinal beam 1 to be welded to the inner side of the sub-frame longitudinal beam 1 , and is fixed to the cable-stayed beam 3 by a plurality of bolts.

The connecting bracket 32 is fixed on the front end surface of the rear frame 2 by means of welding or the like, and the cable-stayed beam 3 is fixed on the connecting bracket 32 by bolts 33 .

In order to increase the welding strength between the sub-frame longitudinal beam connecting plate 31 and the sub-frame longitudinal beam 1, a plurality of plug welding holes 310 may also be formed on the sub-frame longitudinal beam connecting plate 31 to be further welded on the sub-frame longitudinal beam connecting plate 31. The subframe longitudinal beam 1.

In order to conduct the force F (see Figure 1) generated by the weight of the concrete transported by the concrete mixing tank truck and the mixing drum itself on the rear frame 2 to the front of the car body (that is, the direction of the front), the cable-stayed beam 3 extending from the rear frame 2 to the rear of the double bridge center line L of the concrete mixing transport tank truck.

In order to further increase the strength of the subframe, a reinforcing crossbeam 11 located in front of the center line L of the double bridge can be arranged between the two subframe longitudinal beams 1, and a reinforcement crossbeam 11 is fixed between the reinforcement crossbeam 11 and the front crossbeam 12 of the rear frame. An X-shaped scissor beam 4 located inside the two subframe longitudinal beams 1 is provided.

The four ends of the scissor beam 4 are fixedly connected to the reinforcement beam 11 and the front beam 12 of the rear frame through four scissor beam reinforcing plates 43 respectively.

The four scissor beam reinforcing plates 43 are respectively welded to the four ends of the scissor beam 4 , the reinforcing beam 11 and the front beam 12 of the rear frame by plug welding.

The scissors beam 4 comprises four beam arms 41, an upper beam arm connecting plate 42 and a lower beam arm connecting plate 43 (see FIG. 5 ), and the upper beam arm connecting plate 42 and the lower beam arm connecting plate 43 connect the four beams The opposite ends of the arms 41 are clamped in the middle, and plug welding holes are formed on the upper beam arm connecting plate 42 and the lower beam arm connecting plate 43 to connect the upper beam arm connecting plate 42 and the lower beam arm connecting plate 42 and the lower beam arm connecting plate 43 by plug welding.
