Description
The utility model relates to a kind of dumping car.
Dumping car is a kind of transportation means that is used to transport bulk freight, can utilize during unloading hydraulic lifting mechanism with container backward or to laterally inclined certain angle make bulk freight can rely on the deadweight and unload voluntarily.The structure of dumping car is basically by forming with the lower part, i.e. driving engine, vehicle body, chassis, electronic and electrical equipment and hydraulic efficiency pressure system.Wherein vehicle body comprises operator's compartment and loading space; The chassis comprises transmission device, traveling mechanism, steering hardware, stop mechanism; Hydraulic efficiency pressure system has container hydraulic actuating cylinder, container hydraulic actuating cylinder change-over valve, oil pump, fuel tank.The loading space of common common dumping car generally all opens wide, and this makes dumping car that bulk freight easily take place in transit and flies upward unrestrained phenomenon, both environment is polluted, and has certain safety hazard again.In fact people have noticed this problem in the routine life, for example the patent No. is that 95237568 Chinese utility model patents disclosed " Double Tops are added a cover dumping car " adopt shutter door that loading space is sealed, though good effect is arranged on closure, but the mechanism that above-mentioned measure need be set up is complicated, if a large amount of common open type dumping cars is just in use transformed, above-mentioned measure is not ideal enough.
The purpose of this utility model is to propose the closed dumping car that a kind of container has the better simply automatic cover plate of structure.
The technical measures that the utility model is taked are that the cover plate of container forms by forward and backward cover plate is hinged, respectively be fixed with slide rail on two side shields of loading space, front shroud is hinged on the front end of slide rail, the rear end of back shroud is provided with and cooresponding two rollers of two wood side-guides, the base plate front portion of loading space is provided with cylinder support, be connected with the cover plate hydraulic actuating cylinder on the cylinder support, the piston rod and the front shroud of cover plate hydraulic actuating cylinder are hinged; The cover plate hydraulic actuating cylinder is connected with cover plate hydraulic actuating cylinder change-over valve, and fuel tank is connected with adjustable by pass valve, and adjustable by pass valve all is connected with cover plate hydraulic actuating cylinder change-over valve with container hydraulic actuating cylinder change-over valve.
The rear end of slide rail is provided with the pulley locating part.
Be provided with case around the above-mentioned cover plate hydraulic actuating cylinder.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a configuration diagram of the present utility model;
Fig. 2 is that Figure 1A is to view;
Fig. 3 is a hydraulic scheme.
The utility model comprises driving engine, vehicle body, chassis, electronic and electrical equipment and the hydraulic efficiency pressure system that common open type dumping car is had.Wherein vehicle body comprises operator's compartment and loading space, and the chassis comprises transmission device, traveling mechanism, steering hardware, stop mechanism.Loading space has cover plate, cover plate by front shroud 1 and back shroud 2 by hinge 12 hinged forming.Respectively be fixed with slide rail 3 on the both sides plate washer 4 of loading space, slide rail 3 stretches out forward, front shroud 1 is hinged on the front end of slide rail 3 by hinge 10, the rear end of back shroud 2 is provided with and two wood side-guides, 3 cooresponding two rollers 5, roller 5 rolls on each self-corresponding slide rail 3, and the rear end of slide rail 3 is fixed with pulley locating part 6, and current, back shroud is carried out when putting down on slide rail, roller 5 places in the groove of pulley locating part 6, prevents that dumping car from beating because of vibrations cause back shroud in the process of moving.End blocking hook axle 7 is installed on the pulley locating part 6.The base plate front, center of loading space is provided with cylinder support 8, cylinder support is provided with plain bearing housing, cover plate hydraulic actuating cylinder 9 is a sliding block joint with cylinder support, oscillating axle in the plain bearing drives 9 swings of cover plate hydraulic actuating cylinder, the piston rod 11 of cover plate hydraulic actuating cylinder is hinged by hinge 13 with front shroud 1, is provided with case 14 around the cover plate hydraulic actuating cylinder 9.Hydraulic gear of the present utility model is to do some changes on the basis of common open type dumping car hydraulic gear, keep container hydraulic actuating cylinder 20 to be connected with 17 of container hydraulic actuating cylinder change-over valves, keep fuel tank 18 and container hydraulic actuating cylinder change-over valve 17, oil pump 19, connection between the container hydraulic actuating cylinder 20, cover plate hydraulic actuating cylinder 9 is connected with cover plate hydraulic actuating cylinder change-over valve 15, cover plate hydraulic actuating cylinder change-over valve 15 is the third gear four-way cock, wherein one grade is neutral gear, fuel tank 18 is connected with adjustable by pass valve 16, adjustable by pass valve 16 all is connected with cover plate hydraulic actuating cylinder change-over valve 15 with container hydraulic actuating cylinder change-over valve 17, hydraulic actuating cylinder change-over valve 17 and cover plate hydraulic actuating cylinder change-over valve 15 all adopt manual, and above-mentioned described connection is oil pipe and connects.
When the utility model is opened cover plate at needs, drive oil pump 19 earlier, and manual container hydraulic actuating cylinder change-over valve 17 got to the oil return shelves, on manual cover plate hydraulic actuating cylinder change-over valve 15 is placed on and upgrades, oil enters oil pump 19 by adjustable by pass valve 16 from fuel tank 18, manual cover plate hydraulic actuating cylinder change-over valve 15 is delivered in cover plate hydraulic actuating cylinder 9 oil pockets, promote piston rod 11 upward movements, the oil of another oil pocket of cover plate hydraulic actuating cylinder is through cover plate hydraulic actuating cylinder change-over valve 15, manual container hydraulic actuating cylinder change-over valve 17 is got back to fuel tank, cover plate hydraulic actuating cylinder 9 promotes front shroud 1 work in the jacking process be the rotation of axis with hinge 10, and before relying on, hinge 12 between back shroud drives the back shroud front end and lifts, behind the back shroud head sheave 5 along slide rail to front slide, until preceding, back shroud is holded up folded mutually.On otherwise manual cover plate hydraulic actuating cylinder change-over valve 15 was placed on and lowers category, cover plate hydraulic actuating cylinder 9 shrank, and forward and backward cover plate is chevron pointing slowly to be fallen, and covered and put down on slide rail, the container sealing.When manual cover plate hydraulic actuating cylinder change-over valve 15 is placed on the neutral gear, oil is back to manual container hydraulic actuating cylinder change-over valve 17 through manual cover plate hydraulic actuating cylinder change-over valve 15 and enters container hydraulic actuating cylinder 20,20 actions of container hydraulic actuating cylinder.
The utility model container in transit is in closed state, avoids raising of bulk freight to fly and leaks, and plays a part certain to improving city environment; The load carrying ability of all right control vehicle makes vehicle be in the safety load scope.The utility model does not change original common open type dumping car structure substantially, and the cover plate mechanism that is set up is simple in structure, and repacking is convenient and recondition expense is not high.Because front shroud is subjected to is upwards thrust, and it is less relatively to open the needed power of cover plate, so hydraulic actuating cylinder that can selection pressure is less, volume is less neither influences the carrying capacity of dumping car, can utilize original hydraulic efficiency pressure system again.
