Abstract
The utility model provides a dump truck compartment chassis (1), which is welded by a carling (11), and beams (121, 122). The beam (121) at the compartment chassis (1) front is welded on the carling (11), and is welded with a closure (5). The beam (122) at other parts of the compartment chassis (1) is welded on the custom plate of the carling. A heave is formed since the beam (121) at the front part and the beam (122) at other parts are not on the same plane, and the heave can provide the installation and activity space for the lifting body (3) of the dump truck, so as to optimize the collocation of the lifting body (3) without enhancing the dump truck whole bearing surface height, reduce the force coefficient of the lifting oil tank in the lifting body (3), and improve the hydraulic pressure environment of the lifting body (3), and thus to prolong the service life the dump truck .
Description
Technical field
The utility model relates to dumping car, relates in particular to the compartment underframe of dumping car, relates in particular to the compartment underframe of the box-like dumping car of linkage rod group.
Background technology
Along with the develop rapidly of national economy, the national basis construction also strengthens synchronously, thereby more and more to the demand of dumping car, and then also more and more urgent to the demand that improves the dumping car in-use performance.Wherein, described dumping car in-use performance includes safety, service life, dead weight of vehicle, car load charge material amount factor of utilization, and the efficiency of operation etc. of dumping car.
Figure 1 shows that the body frame structure for automotive scheme drawing of traditional dumping car, because connecting rod assembly lifting mechanism 2 installing spaces and main frame 4 can utilize the restriction in space, traditional method is to improve the depth of section of subframe 3 or compartment underframe 1 longeron 11, this has highly generally been accomplished between 260 millimeters to 300 millimeters, with installation and the activity space of stopping lifting mechanism 2.Certainly will improve the closed height of subframe 3 like this, cause the car load center of gravity of dumping car to improve with compartment underframe 1.
Though said method has been optimized the layout of lifting mechanism, reduce elevating ram and be subjected to force coefficient, prolong the dumping car purpose in service life thereby reach; But seriously sacrificed the carrying surface height of dumping car, made dumping car car load deterioration of safety,, therefore had very big potential safety hazard such as very easily turning on one's side when the operation of rugged hill path.
The utility model content
At above-mentioned the deficiencies in the prior art, the utility model purpose is to provide a kind of compartment underframe of dumping car, and this compartment underframe can effectively reduce the carrying surface height of dumping car, thereby reduces the possibility that rollover takes place dumping car.
For achieving the above object, the utility model provides a kind of compartment underframe of dumping car, and it is formed by crossbeam and longeron assembly welding; Wherein, the crossbeam of underframe front portion, described compartment is welded on the described longeron and is welded goes up the envelope frame, and the crossbeam at other positions is welded on the web of described longeron.
For the compartment underframe of above-mentioned dumping car, at welding tractor railway carriage or compartment, underframe upper berth, described compartment base plate, the bossing that is welded on the crossbeam position formation on the described longeron in underframe front portion, described compartment constitutes the space that holds tipper lifting mechanism.
For the compartment underframe of above-mentioned dumping car, the longeron depth of section of described compartment underframe is between 120 millimeters to 160 millimeters, and the described section of beam height that is welded on the described longeron is 140 millimeters.
Technical solutions of the utility model can effectively improve the installation and the activity space of lifting mechanism in the dumping car, thereby can optimize lifting mechanism under the situation that does not improve dumping car car load carrying surface height preferably arranges, reduce the force coefficient that is subjected to of elevating ram in the described lifting mechanism, improve the hydraulic pressure environment in the described lifting mechanism, and then prolong the car load service life of described dumping car.
Description of drawings
Fig. 1 is the front view of dumping car vehicle frame in the prior art;
Fig. 2 A is the front view of the utility model dumping car vehicle frame;
Fig. 2 B is the birds-eye view of Fig. 2 A;
Fig. 2 C is the cutaway view along AA shown in Fig. 2 A.
The specific embodiment
Shown in Fig. 2 A, Fig. 2 B and Fig. 2 C, specifically implement technical scheme provided by the utility model.
At first, adopt low cross section longeron 11 to become compartment underframe 1 with crossbeam 121,122 assembly weldings, wherein, the crossbeam 121 of underframe 1 front portion, described compartment is welded on the described low cross section longeron 11, and the crossbeam 122 at underframe 1 other positions, described compartment is welded on the web of described low cross section longeron 11.And the depth of section of described low cross section longeron is between 120 millimeters to 160 millimeters, and the described depth of section that is welded on the crossbeam 121 on the described low cross section longeron 11 is 140 millimeters.
After the assembly welding of finishing above-mentioned low cross section longeron 11 and crossbeam 121,122, be welded on crossbeam 121 positions on the described low cross section longeron 11 envelope frame 5 on the compartment underframe that is welded in compartment underframe 1 front portion.At last, welding tractor railway carriage or compartment, shop base plate 7 on whole described compartment underframe 1.
Like this, on the one hand, owing to adopt low cross section longeron 11 greatly the car load carrying surface height and the car load deadweight of degree reduction dumping car, thus reduce the possibility that rollover takes place dumping car, and then the car load safety in operation and the ride comfort of raising dumping car.
On the other hand, owing to the crossbeam 121 of compartment underframe 1 front portion and the crossbeam 122 at compartment underframe 1 other positions have not formed a bossing 8 at grade, this bossing 8 can provide the installation and the activity space of lifting mechanism 3 in the described dumping car, thereby can when reducing dumping car car load carrying surface height, optimize the layout of described lifting mechanism 3 preferably, reduce the force coefficient that is subjected to of elevating ram in the described lifting mechanism 3, improve the hydraulic pressure environment in the described lifting mechanism 3, and then prolong the car load service life of described dumping car.
What need statement is that the above-mentioned utility model content and the specific embodiment are intended to prove the practical application of technical scheme that the utility model provides, and should not be construed as the qualification to the utility model protection domain.Those skilled in the art are in spirit of the present utility model and principle, when doing various modifications, being equal to and replacing or improve.Protection domain of the present utility model is as the criterion with appended claims.
