The utility model discloses a further set up to: the aircraft bonnet opening angle adjusting device is characterized in that a first pin shaft is rotatably connected between the base and the air spring, a second pin shaft is rotatably connected between the aircraft bonnet sliding groove plate and the air spring, the first pin shaft and the second pin shaft are parallel to each other, and a structure for increasing the opening angle of an aircraft bonnet is arranged between the second pin shaft and the aircraft bonnet sliding groove plate.
The utility model discloses a further set up to: the structure for increasing the opening angle of the hood is a sliding groove formed in a hood sliding groove plate, the length direction of the sliding groove is perpendicular to the axial direction of the second pin shaft, and the second pin shaft is connected to the sliding groove in a sliding mode.
The utility model discloses a further set up to: the hood chute plate is bolted to the hood.
The utility model discloses a further set up to: the base is provided with a clamping groove connected with the road roller body in a buckling mode, and the base is provided with a connecting hole connected with the road roller body through a bolt.
The utility model discloses a further set up to: the aircraft bonnet is seted up and is used for observing the observation window of engine, the observation window is provided with toughened glass.
To sum up, the utility model discloses following beneficial effect has:
1) when the engine cover needs to be opened, the gas spring takes the base as a basis and the first pin shaft as a rotating shaft, and generates thrust to enable the engine cover sliding groove plate to drive the engine cover to be opened, so that workers can conveniently overhaul and maintain the engine;
2) when the hood is opened to the maximum stroke of the gas spring, the opening angle of the hood cannot meet the requirements of maintenance, but the hood can be continuously opened because the hood sliding groove plate and the second pin shaft can relatively slide through the sliding groove until the stroke of the second pin shaft in the hood sliding groove is finished, and the opening angle of the hood can meet the requirements of maintenance at the moment; therefore, the maintenance of the parts in the hood is carried out without dismantling the hood;
3) the base is convenient to disassemble and assemble from the body of the road roller through the connecting hole of the groove clamping machine;
4) the running condition of the engine can be conveniently observed through the observation window.
Drawings
FIG. 1 is a schematic structural view of the gas spring in a contracted state;
fig. 2 is a schematic structural view of the gas spring extending and opening the hood of the present invention.
The corresponding part names indicated by the numbers in the figures: the device comprises a base 1, a first pin shaft 2, a gas spring 3, a second pin shaft 4, a hood sliding groove plate 5, a hood 6, a sliding groove 7, a clamping groove 8, a connecting hole 9 and an observation window 10.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the drawings and the specific embodiments.
As shown in fig. 1 and 2, the utility model provides an engine bonnet opening mechanism, including aircraft bonnet 6, there is aircraft bonnet chute board 5 aircraft bonnet 6 inner wall through bolt fixed mounting, and aircraft bonnet chute board 5 rotates and is connected with air spring 3 to rotate through installation second round pin axle 4 between air spring 3 and the aircraft bonnet chute board 5 and be connected, first round pin axle 2 is parallel to each other with second round pin axle 4, and the other end of air spring 3 rotates and is connected with base 1, realizes rotating through installation first round pin axle 2 between base 1 and the air spring 3 and is connected, and base 1 fixed mounting is in the road roller organism. When aircraft bonnet 6 is opened to needs, air spring 3 uses base 1 as the basis, and first round pin axle 2 is the rotation axis, produces thrust and makes aircraft bonnet chute board 5 drive aircraft bonnet 6 and open, from making things convenient for the workman to overhaul and maintain the engine.
In order to further increase the opening angle of the hood 6, a structure for increasing the opening angle of the hood 6 is arranged between the second pin shaft 4 and the hood sliding groove plate 5, the structure for increasing the opening angle of the hood 6 is a sliding groove 7 formed in the hood sliding groove plate 5, the length direction of the sliding groove 7 is perpendicular to the axial direction of the second pin shaft 4, and the second pin shaft 4 is connected to the sliding groove 7 in a sliding mode. When the hood 6 is opened to the maximum stroke of the gas spring 3, the opening angle of the hood 6 cannot meet the requirements of maintenance, but the hood 6 can be continuously opened because the hood sliding groove plate 5 and the second pin shaft 4 can relatively slide through the sliding groove 7 until the stroke of the second pin shaft 4 in the sliding groove 7 of the hood 6 is finished, and at the moment, the opening angle of the hood 6 can meet the requirements of maintenance; thereby performing maintenance on the internal parts of the hood 6 without removing the hood 6.
