Abstract
The utility model relates to a front lifting-up dumper without a subframe, which comprises a chassis, a carriage, an oil cylinder support and a hydraulic system, wherein the hydraulic system is installed on the oil cylinder support. The front lifting-up dumper without the subframe is characterized in that two through holes are respectively arranged at the right parts of the front longitudinal beam and the rear longitudinal beam of the chassis, a rear turnover shaft assembly penetrates through the two through holes, the bottom of the right end of the carriage is hinged with the chassis through the rear turnover shaft assembly, two attaching plates are respectively welded at the front end and the rear end of the rear turnover shaft assembly, the attaching plates are perpendicular to the axis of the rear turnover shaft assembly, the rear turnover shaft assembly is fixedly bolted with the longitudinal beams of the chassis through high-strength bolts, the front side and the rear side of the bottom part of the oil cylinder support are respectively and vertically connected with two connecting plates, and the two connecting plates are fixedly connected with the longitudinal beam at the right end of a cab through high-strength bolts. The front lifting-up dumper without the subframe has the advantages that the number of parts is reduced, the cost is reduced and the production efficiency is improved; the gravity center of the entire dumper is reduced when the dumper is on full load and rollover accidents are reduced; and the curb mass is greatly reduced, the pass mass utilization coefficient is improved, the fuel consumption is reduced, the transportation cost is saved, and goals of energy saving and emission reduction are achieved.
Description
Technical field
The utility model relates to a kind of dumping car, refers to a kind of no subframe sinciput dumping car especially.
Background technology
Tradition sinciput dumping car comprises the chassis; subframe; the compartment; cylinder support and hydraulic efficiency pressure system; subframe is located on the chassis; rear portion at the bottom of the compartment is hinged by the rear end of back trip shaft assembly and subframe; back trip shaft assembly is made up of the axle sleeve at back trip shaft and trip shaft two ends, back; cylinder support is installed on the front end of subframe; hydraulic efficiency pressure system is installed on the cylinder support; subframe mainly plays the protection chassis and railway carriage and other parts is installed; but the quality of the whole equipment of this dumping car is big; both heavy; increase manufacturing cost again; in order to reduce unloaded WT significantly; need simplify dump truck body, reach the lightweight purpose, but can not influence its in-use performance.
The utility model content
The purpose of this utility model is to provide a kind of no subframe sinciput dumping car, and its designs simplification, cost reduce and do not influence in-use performance.
To achieve these goals, technical solution of the present utility model is: a kind of no subframe sinciput dumping car, comprise the chassis, back trip shaft assembly, the compartment, cylinder support and hydraulic efficiency pressure system, described hydraulic efficiency pressure system is installed on the cylinder support, before the wherein said chassis, the floor side member right part offers two through holes respectively, described back trip shaft assembly passes two through holes, the bottom of described compartment right-hand member is hinged by back trip shaft assembly and described chassis, the rear and front end of described back trip shaft assembly is welded a pasting board respectively, the axis normal of described pasting board and described back trip shaft assembly, the longeron on described back trip shaft assembly and chassis is spirally connected fixing by high strength bolt, the vertical respectively a plate that connects of the front and back side of described cylinder support bottom, two described connecting panels are spirally connected fixing by the front side member left part on high strength bolt and chassis.
The utility model does not have subframe sinciput dumping car, and wherein said cylinder support and connecting panel are fixed together by welding or being spirally connected.
After adopting such scheme, the utility model does not have subframe sinciput dumping car by back trip shaft assembly is installed on the chassis, the bottom of compartment right-hand member directly is articulated and connected by back trip shaft assembly and chassis, and cylinder support is directly installed on the longeron left end on chassis, sinciput hydraulic actuating cylinder lifting by hydraulic efficiency pressure system, the trip shaft assembly is the purpose that invert center jack-up railway carriage reaches unloading later on, this dumping car has saved designs simplification behind the subframe, unloaded WT is reduced, cost-cutting, and do not influence the in-use performance of unloading in the compartment.
Description of drawings
Fig. 1 is the main TV structure scheme drawing that the utility model does not have subframe sinciput dumping car;
Fig. 2 is chassis master's TV structure scheme drawing that the utility model does not have subframe sinciput dumping car;
Fig. 3 is the installation site scheme drawing that the utility model does not have the cylinder bracket of subframe sinciput dumping car.
Below in conjunction with accompanying drawing, the utility model is described further by embodiment;
The specific embodiment
See also shown in Figure 1, the utility model does not have subframe sinciput dumping car and comprises chassis 1, back trip shaft assembly 2, compartment 3, cylinder support 4 and hydraulic efficiency pressure system 5, before the chassis 1, the floor side member right part offers two through holes respectively, described back trip shaft assembly 2 passes two through holes, the bottom of compartment 3 right-hand members is hinged with chassis 1 by back trip shaft assembly 2, in conjunction with shown in Figure 2, back trip shaft assembly 2 is made up of the axle sleeve 22 at back trip shaft 21 and trip shaft 21 two ends, back, the rear and front end of back trip shaft assembly 2 is welded a pasting board 6 respectively, the axis normal of pasting board 6 and back trip shaft assembly 2, back trip shaft assembly 2 is spirally connected fixing with the longeron on chassis 1 by high strength bolt 7, in conjunction with shown in Figure 3, the vertical respectively welding a plate 8 of the front and back side of cylinder support 4 bottoms, two connecting panels 8 front side member left part by high strength bolt 9 and chassis 1 is spirally connected fixing, and hydraulic efficiency pressure system 5 is installed on the cylinder support 4.
During use, during the hydraulic actuating cylinder jack-up railway carriage 3 of hydraulic efficiency pressure system 5, trip shaft assembly 2 is the invert center lifting after the railway carriage, and back trip shaft assembly 2 passes to chassis 1 by high strength bolt 7 and axle sleeve 22 with power, realizes replacing the function of subframe.
The utility model does not have subframe sinciput dumping car by back trip shaft assembly is installed on the chassis, the bottom of compartment right-hand member directly is articulated and connected by back trip shaft assembly and chassis, and cylinder support is directly installed on the longeron left end on chassis, sinciput hydraulic actuating cylinder lifting by hydraulic efficiency pressure system, the trip shaft assembly is the purpose that invert center jack-up railway carriage reaches unloading later on, the advantage of this no subframe sinciput dumping car is: (1) reduces parts, and cost-cutting is enhanced productivity; (2) reduce at full load car load center of gravity, reduce the generation of roll-over accident; (3) reduce curb mass greatly, improve charge material amount factor of utilization, reduce fuel oil consumption, save traffic cost, thereby reach the purpose of energy-saving and emission-reduction.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineering staff in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
