Description

The concrete truck transportation tank car

Technical field

The utility model relates to a kind of concrete truck transportation tank car, relates in particular to a kind of chassis ridgepole additional strengthening of concrete truck transportation tank car.

Background technology

Constructional feature according to the concrete truck transportation tank car, the mixer barreles that bear on the chassis etc. are gone up the dress part and institute's handling load (cement concrete) load is concentrated load, load lays respectively at the forebay place that reductor is installed and the afer bay place that supports the mixer barrel support roller is installed, and the afer bay of concrete truck transportation tank car is positioned on the rear overhang on chassis, after loading cement concrete, because the rear overhang of chassis ridgepole partly is a cantilever position, the distortion that easily causes the chassis ridgepole rear overhang under the loading that the afer bay transmission comes is sunk, and then cause the damage of chassis and afer bay, when vehicle ' when the rough road surface, because it is higher that the force position position of goods is born at the afer bay place, thereby make that afer bay place torsional deflection is bigger, this torsional deflection is delivered to chassis ridgepole by the bindiny mechanism of last dress and bottom chassis with distortion simultaneously, thereby causes the chassis ridgepole damage.

The utility model content

A purpose of the present utility model is to provide a kind of concrete truck transportation tank car, and it increases the non-deformability of afer bay place chassis ridgepole by between afer bay and subframe longeron oblique straining beam being set.

Another purpose of the present utility model is to provide a kind of concrete truck transportation tank car, and it is provided with the non-deformability that X-shaped scissors beam further increases afer bay place chassis ridgepole by the inboard at two chassis ridgepoles.

For achieving the above object, the utility model provides a kind of concrete truck transportation tank car, comprise subframe and be separately fixed at forebay and the afer bay that is used to support tank body on the rear and front end of described subframe, described subframe comprises two subframe longerons, be positioned at the afer bay front cross rail and the afer bay after cross member of described afer bay below, it is characterized in that, between described afer bay and described two subframe longerons, be connected with an oblique straining beam respectively, between two described subframe longerons, be provided with the deep beam that is positioned at place, concrete truck transportation tank car doube bridge line of centers the place ahead, between described deep beam and described afer bay front cross rail, be installed with the X-shaped scissors beam that is positioned at described two subframe longeron inboards.

Compared with prior art, advantage of the present utility model and beneficial effect are: by skewing straining beam and in the inboard of two subframe longerons the scissors beam is set between afer bay and subframe longeron, make that the suffered application force of afer bay shifts to the doube bridge centerline when loading cement concrete, thereby actv. reduces the application force of afer bay to the crossbeam rear overhang, simultaneously owing to increased the anti-twist ability of last dress self, reduce the torsional deflection amount, reached the purpose of the torsional deflection that reduces chassis ridgepole.

The specific embodiment

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

As Fig. 1, Fig. 2 and shown in Figure 6, concrete truck transportation tank car of the present utility model comprises that subframe and the rear and front end that is fixed on described subframe are used to support the afer bay 2 and the forebay 7 of tank body.Described subframe comprises two subframe longerons 1, is positioned at the afer bay front cross rail 12 and the afer bay after cross member 13 of afer bay 2 belows.

Between afer bay 2 and two subframe longerons 1, be connected with two oblique straining beams 3 respectively.

As depicted in figs. 1 and 2, an end of each oblique straining beam 3 is fixed in the inboard of subframe longeron 1 by subframe longeron connecting panel 31, and the other end is fixed in afer bay 2 by connecting support 32.

Subframe longeron connecting panel 31 being welded in the inboard of subframe longeron 1, and is fixed in oblique straining beam 3 by a plurality of bolts along the longitudinal extension of subframe longeron 1.

Connect support 32 and be fixed in the front end face of afer bay 2 by modes such as welding, tiltedly straining beam 3 is fixed in connection support 32 by bolt 33.

In order to increase the weld strength between subframe longeron connecting panel 31 and the subframe longeron 1, can also on subframe longeron connecting panel 31, be formed with a plurality of plug weldings hole 310 further to be welded in described subframe longeron 1 by plug welding.

For cement concrete that the concrete truck transportation tank car is transported and the weight of mixing tube self act on the power F (referring to Fig. 1) that produced on the after-frame 2 to the front portion of car body (being the direction of headstock) conduction, oblique straining beam 3 extends to the rear of the doube bridge centre line L of concrete truck transportation tank car from afer bay 2.

In order further to increase the intensity of subframe, can between two subframe longerons 1, be provided with the deep beam 11 that is positioned at place, doube bridge centre line L the place ahead, between deep beam 11 and afer bay front cross rail 12, be installed with the X-shaped scissors beam 4 that is positioned at two subframe longeron 1 inboards.

Four ends of scissors beam 4 are fixed in deep beam 11 and described afer bay front cross rail 12 by four scissors beam brace panels 43 respectively.

Four scissors beam brace panels 43 are welded in four ends, deep beam 11 and the described afer bay front cross rail 12 of scissors beam 4 respectively by plug welding.

Scissors beam 4 comprises four beam arms 41, goes up beam arm connecting panel 42 and following beam arm connecting panel 43 (referring to Fig. 5), described beam arm connecting panel 42 and the described beam arm connecting panel 43 down gone up be being clipped in the middle to top ends of four beam arms 41, and described go up form on beam arm connecting panel 42 and the described beam arm connecting panel 43 down the plug welding hole with will describedly go up by plug welding beam arm connecting panel 42 and described under beam arm connecting panel 43 and four beam arms 41 be welded as a whole.

In order further to increase the intensity of subframe, two subframe longeron knightheads 5 can also be set, an end of each described subframe longeron knighthead 5 is fixed in deep beam 11, and the other end is fixed in the inboard of subframe longeron 1.

After concrete truck transportation tank car of the present utility model has loaded cement concrete, the weight of cement concrete and mixer barrel self can apply directed force F to afer bay 2, because oblique straining beam 3 has all been designed in the both sides between afer bay 2 and subframe longeron 1, between two subframe longerons 1, set up deep beam 11, and be provided with subframe longeron knighthead 5, afer bay 2 suffered directed force F are transferred to the front portion by actv., reduced by laggard 2 deflection greatly, also reduced the sinking distortion of main car frame crossbeam 6 rear overhang S; Simultaneously, strengthened the anti-twist ability at last dress afer bay 2 places greatly, in the time of the rough road surface of vehicle ', can reduce to go up the torsional deflection of dress self, thereby reduced effect the chassis.

Above-described only is preferable possible embodiments of the present utility model; described embodiment is not in order to limit scope of patent protection of the present utility model; therefore the equivalent structure done of every utilization specification sheets of the present utility model and accompanying drawing content changes, and in like manner all should be included in the protection domain of the present utility model.
