The utility model has the advantages that: the driving mechanism can automatically adjust the height and wheel pressure of the travelling wheels, and has a large adjusting range and stronger adaptability; the ingenious connection mode ensures that the stress point of the travelling wheel and the stress direction are always on the same straight line; the manual pump is matched, so that manual and electric opening and closing functions can be freely switched.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a side view of the present invention.
Wherein: 1. a connecting frame; 2. a hexagon head bolt; 3. a hydraulic cylinder; 4. a bolt; 5. a ball head of a piston rod of the hydraulic cylinder; 6. a ball joint connection plate; 7. a traveling wheel; 8. an output shaft; 9. a motor reducer; 10. a track; 11. an electric hydraulic pump station; 12. a manual hydraulic pump; 13. a door body.
Detailed Description
As shown in fig. 1-2, a driving mechanism for protecting a hangar door comprises an electric hydraulic pump station 11, a hydraulic cylinder 3, a motor reducer 9 and a traveling wheel 7, wherein the hydraulic cylinder 3 is fixed on a connecting frame 1 through a bolt 4, the connecting frame 1 is fixed on a door body 13 through a hexagon head bolt 2, the electric hydraulic pump station 11 is fixed above the connecting frame 1, a manual hydraulic pump 12 is arranged on the side surface of the electric hydraulic pump station 11, a hydraulic cylinder piston rod ball head 5 is arranged at the bottom of the hydraulic cylinder 3, the traveling wheel 7 is connected with the hydraulic cylinder piston rod ball head 5 through a ball socket connecting plate 6, the motor reducer 9 is connected with an output shaft 8 of the traveling wheel 7, and a wheel body of the traveling wheel 7 is in constant-pressure tread contact with a lower track 10.
The track 10 has the slope, and the walking wheel 7 is under the effect of electronic hydraulic pump station 11, pneumatic cylinder 3, and the automatically regulated height guarantees invariable wheel pressure all the time between the tread of track 10, guarantees that the gate is normally opened and close.
The piston rod of the hydraulic cylinder is connected with the walking wheel 7 in a ball head and ball socket connection mode, so that the direction can be automatically finely adjusted, and the stress point of the walking wheel 7 and the stress direction are always on the same straight line.
When the motor speed reducer 9 breaks down or has power failure, the walking wheels 7 are lifted to be separated from the track by operating the manual hydraulic pump 12, and the door leaf can be opened and closed by manual pushing and pulling or other modes.
The driving mechanism of the utility model can automatically adjust the height and wheel pressure of the walking wheel, and has large adjusting range and stronger adaptability; the ingenious connection mode ensures that the stress point of the travelling wheel and the stress direction are always on the same straight line; the manual pump is matched, so that manual and electric opening and closing functions can be freely switched.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention should be included in the protection scope defined by the claims of the present invention.
