[0022] In order to make the purpose, content and advantages of the utility model more clear, the specific implementation of the utility model is described in further detail below in combination with the drawings and examples.
[0023] The utility model provides a damper type fender for special vehicle, the structure is as shown in Figure 1a and 1b , mainly includes hydraulic damping hinge 1, hinge mounting seat 2, pressing plate 3, fender 4 and limiting support 5, wherein, as shown in Figure 2a and 2b , hydraulic damping hinge 1 includes upper hinge plate 11, lower hinge plate 12 and hinge middle shaft 13.
[0024] Hinge mounting seat 2 is welded in the lower edge of the upper vertical deck of special vehicle. The upper hinge plate 11 of hydraulic damping hinge 1 is fixed on hinge mounting seat 2 by bolt and nut, the lower hinge plate 12 of hydraulic damping hinge 1 is fixed on the upper edge of fender 4 by bolt and nut, and the upper hinge plate 11 and the lower hinge plate 12 are connected by hinge middle shaft 13. The damping torque of internal hydraulic oil is adjusted by adjusting valve in one end of hinge middle shaft 13, so as to adjust the damping coefficient of hydraulic damping hinge 1, control the force and falling speed of fender 4 when being folded up and down. Limiting support 5 is installed in the lower edge of the upper vertical deck, and is used for limiting fender 4 when fender 4 is in the vertical completely folded state, to avoid the interference between fender 4 and action system. Pressing plate 3 is used for preventing fender 4 from shaking due to road bumping during the driving of special vehicle, by tightly pressing adjacent two fenders 4 on limiting support 5 through bolt.
[0025] The damper type fender downward folding process is as follows:
[0026] As shown in Figure 3 and 4 , fender 4 is turned down according to the force set by hinge middle shaft 13, and the hydraulic oil in hinge middle shaft 13 will flow through the small hole of the internal piston, and the oil flow speed is significantly slowed down due to the small hole diameter, thereby achieving the buffering effect, avoiding the rapid and violent downward folding of fender 4 under the action of gravity, and avoiding the safety problems such as impact and hand clamping. After fender 4 is turned down to limiting support 5, pressing plate 3 is adjusted from the vertical angle to the horizontal angle, and the fixing bolt between pressing plate 3 and limiting support 5 is tightened, so that adjacent fender 4 can be tightly pressed.
[0027] The process of the fender upturning and unfolding is as follows:
[0028] As shown in Figure 5 and 6 , the fixing bolt between the pressing plate 3 and the limiting support 5 is loosened, so that the pressing plate 3 is turned from a horizontal angle to a vertical angle under the action of gravity, and no longer exerts a pressing force on the adjacent fender 4. The fender 4 is turned upward according to the force set by the hinge central shaft 13, and since the moment generated by the gravity of the fender 4 is smaller than the damping moment generated by the hydraulic oil inside the hinge central shaft 13, the fender 4 can be stopped and stationary at any angle within the range of 180° of the upturning, without the need for additional support and fixation, so as to ensure that the maintenance personnel of the action system can safely perform maintenance.
[0029] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and deformations can be made without departing from the technical principles of the present application, and these improvements and deformations should also be considered as the protection scope of the present application.
