Abstract
The utility model relates to an opening and closing device of a sealed cover of a vehicle carriage, which is especially suitable for dump trucks for transporting slag soil, sand stone, building rubbish and coal. The utility model comprises power cases, a coupling rod, an axle seat, a power arm, a transverse beam, a driven arm, a joint bearing and a hydraulic power unit, wherein two power cases are symmetrically fixed and installed on the upper part of the front outer side of a vehicle carriage, and the power case is composed of a power case body, a single-acting hydraulic cylinder, a chain, a chain pulley shaft and an adjusting rod. The single-acting hydraulic cylinder is installed in the power case body, and the piston rod of the single-acting hydraulic cylinder is hinged with one end of the chain which is engaged with a chain pulley on the chain pulley shaft. The other end of the chain is hinged with the adjusting rod which is connected with the coupling rod by threads. The opening and closing device of a sealed cover adopts a transmission mechanism in which the chain is engaged with the chain pulley, the occupied space is small, and the power transmission is reliable. The utility model can be matched with the size of a vehicle and the width of the vehicle carriage because the utility model adopts the adjusting rod device.
Description
Affiliated technical field;
The utility model is about automobile sealed lid arrangement, specifically about a kind of automobile bodies seal cover cap open and close device.
Technical background;
The seal cover cap open and close device that present transport of loose cargo automobile bodies installs additional generally adopts a four-link mechanism is installed on the compartment, by the cylinder pushes four-bar linkage seal cover cap is opened or closed, be 01236785.0 as the patent No. and be called that the utility model patent of " railway carriage or compartment, compartment lid four-bar linkage hydraulic control device " discloses a kind of link rod hydraulic control device.Its weak point is; Loaded down with trivial details during installation, work capacity is big; Four-bar linkage element quantity is many, and structure is looser, and the effect requisite space is big; Be subjected to accidental damage easily.
The utility model content:
The utility model purpose is, has overcome the above-mentioned defective that exists in the known technology, a kind of compact conformation is provided, rational automobile bodies seal cover cap open and close device is set, and is particularly useful for transporting the dumping truck of dregs, sandstone, building waste, coal.
To achieve these goals, the utility model provides a kind of automobile bodies seal cover cap open and close device, comprises headstock, pitman, axle bed, power arm, crossbeam, slave arm, oscillating bearing, hydraulic power unit; This headstock is made of power box, single-action hydraulic cylinder, chain, sprocket shaft, adjust bar; Described single-action hydraulic cylinder is installed in the headstock, and the piston rod of single-action hydraulic cylinder and chain one end are hinged, the sprocket engagement on chain and the sprocket shaft, and the other end and the adjust bar of chain are hinged, adjust bar and pitman thread connection.
Described axle bed is fixed on upper end, both sides, compartment, one oscillating bearing is installed in the axle bed, one end of sprocket shaft cooperates installation with oscillating bearing, one end and the sprocket shaft of power arm are fixedly connected, the other end and seal cover cap are hinged, be fixedly connected by crossbeam between two power arms, slave arm one end and seal cover cap are fixedly connected, and the other end and boxcar are hinged.
Two headstock symmetries are fixedly mounted on outer upper before the boxcar, are connected by pitman between two headstocks, and hydraulic power unit is fixedly mounted on the headstock below.
The utility model beneficial effect is;
1. simple in structure; Because it is little to have adopted chain sprocket ingear transmission device to take up room, transferring power is reliable.
2. applicability is strong; Owing to adopted the size of adjust bar device to vehicle, the width in compartment is all applicable.
3. reliability height; Since oscillating bearing has been installed to the compartment distortion in using in axle bed, the distortion of colliding with of seal cover cap, and having a contest of each rotary part do not influence the open and close of seal cover cap.
Description of drawings
Fig. 1 is the structural representation of the utility model actuating device;
Fig. 2 is the schematic side view of the utility model actuating device;
Fig. 3 is an integral structure scheme drawing of the present utility model.
Mark among the figure:
