Description

Technical Field

[0001] The invention belongs to the technical field of special vehicles, and in particular relates to a damping fender for a special vehicle. Background Art

[0002] At present, the fenders of special vehicles are arranged at the outermost side of the motion system and are essential components for protecting the motion system. When performing daily maintenance and emergency repairs on the motion system, the fenders need to be flipped up and fixed or removed to provide sufficient maintenance space for maintenance personnel. Due to the complex and changeable terrain in which special vehicles are used, there is a risk of the fenders suddenly falling due to a sudden slip of the hand during the flipping process of the fenders or the fenders are not firmly fixed after flipping up. The instantaneous impact force will cause great damage to the maintenance personnel of the motion system. Therefore, it is necessary to design a damping fender for special vehicles that can achieve slow opening and closing of the fenders at any opening angle. Summary of the invention

[0003] 1. Technical issues to be resolved

[0004] The present invention provides a damping fender for a special vehicle, so as to solve the technical problem of realizing the slow opening and closing of the fender at any opening angle.

[0005] (II) Technical solution

[0006] In order to solve the above technical problems, the present invention proposes a damping fender for special vehicles, which comprises a hydraulic damping hinge, a hinge mounting seat, a pressure plate, a fender and a limit support, wherein the hydraulic damping hinge comprises an upper hinge plate, a lower hinge plate and a hinge center axis; wherein,

[0007] The hinge mounting seat is fixedly installed on the lower edge of the upper vertical deck of the special vehicle; the upper hinge plate of the hydraulic damping hinge is fixed on the hinge mounting seat, and the lower hinge plate of the hydraulic damping hinge is fixed on the upper edge of the fender, and the upper hinge plate and the lower hinge plate are connected by the hinge center axis; by adjusting the damping torque of the hinge center axis, the damping coefficient of the hydraulic damping hinge is adjusted to control the force and falling speed of the fender when flipping up and down; the limit support is installed on the lower edge of the upper vertical deck, which is used to limit the fender when the fender is in a vertically completely fallen and retracted state, so as to avoid interference between the fender and the action system; the pressure plate presses two adjacent fenders against the limit support to prevent the fender from shaking during the driving of the special vehicle.

[0008] Furthermore, the hinge mounting seat is welded to the lower edge of the upper vertical deck of the special vehicle.

[0009] Furthermore, the upper hinge plate is fixed to the hinge mounting seat by bolts and nuts, and the lower hinge plate is fixed to the upper edge of the fender by bolts and nuts.

[0010] Furthermore, the internal hydraulic oil is regulated by a regulating valve at one end of the hinge center axis to generate a damping torque.

[0011] Furthermore, the pressure plate presses two adjacent fenders onto the limiting support by means of bolts.

[0012] (III) Beneficial effects

[0013] The present invention provides a damping fender for special vehicles, comprising a hydraulic damping hinge, a hinge mounting seat, a pressure plate, a fender and a limit support. The hydraulic damping hinge comprises an upper hinge plate, a lower hinge plate and a hinge center axis.

[0014] The installation position of the present invention is the same as that of a traditional special vehicle, which is located outside the action system. A hinge mounting seat is arranged at the lower edge of the upper vertical deck, and the upper hinge plate of the hydraulic damping hinge is fixed on the hinge mounting seat, and the lower hinge plate of the hydraulic damping hinge is fixed on the upper part of the fender. The upper hinge plate and the lower hinge plate of the hydraulic damping hinge are connected through the hinge center axis. The damping coefficient of the hydraulic damping hinge is adjusted by a regulating valve at one end of the hinge center axis, so as to control the force and falling speed of the fender when it turns up and down. The limit support is used for limiting and fixing when the fender is in a vertically completely falling state. On the one hand, it ensures that any angle within the 180° range of the fender can achieve a paused static state without the need for additional support and fixation; on the other hand, by adjusting the damping coefficient of the hydraulic damping hinge, the speed of the fender turning up and down can be controlled, which has a buffering effect and prevents damage caused by instantaneous impact caused by sudden falling.

[0015] The damping fender for special vehicles has a simple structure, mature hydraulic damping hinge technology, strong versatility, easy implementation, high reliability, quickness and convenience, and can improve the safety and efficiency of special vehicle motion system maintenance.

[0022] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0023] This embodiment provides a damping fender for a special vehicle, and its structure is as follows: Figure 1a and 1b As shown, it mainly includes a hydraulic damping hinge 1, a hinge mounting seat 2, a pressure plate 3, a fender 4 and a limit support 5. Figure 2a and 2b As shown, the hydraulic damping hinge 1 comprises an upper hinge plate 11 , a lower hinge plate 12 and a hinge center axis 13 .

[0024] The hinge mounting seat 2 is welded to the lower edge of the upper vertical deck of the special vehicle. The upper hinge plate 11 of the hydraulic damping hinge 1 is fixed to the hinge mounting seat 2 by bolts and nuts, and the lower hinge plate 12 of the hydraulic damping hinge 1 is fixed to the upper edge of the fender 4 by bolts and nuts. The upper hinge plate 11 and the lower hinge plate 12 are connected by the hinge center axis 13. The damping torque generated by the internal hydraulic oil is adjusted by the regulating valve at one end of the hinge center axis 13, thereby adjusting the damping coefficient of the hydraulic damping hinge 1 to control the force and falling speed of the fender 4 when flipping up and down. The limit support 5 is installed at the lower edge of the upper vertical deck, which is used to limit the fender 4 when the fender 4 is in a vertically completely fallen and retracted state, so as to avoid interference between the fender 4 and the action system. The pressure plate 3 presses two adjacent fenders 4 on the limit support 5 by bolts, which is used to prevent the fender 4 from shaking due to road bumps during the driving of the special vehicle.

[0025] The closing process of the damping fender is as follows:

[0026] like Figure 3 and 4 As shown, the fender 4 is flipped down according to the force set by the hinge center axis 13, and the hydraulic oil in the hinge center axis 13 will flow through the small hole of the piston inside it. Due to the small aperture of the small hole, the oil flow speed is significantly slowed down, thereby playing a buffering effect, preventing the fender 4 from flipping down quickly and violently under the action of gravity, thereby avoiding safety issues such as impact and pinching. After the fender 4 is flipped down to the limit support 5, the pressure plate 3 is adjusted from a vertical angle to a horizontal angle, and the fixing bolts between the pressure plate 3 and the limit support 5 are tightened, so that the adjacent fenders 4 can be pressed tightly.

[0027] The process of the damping fender flipping up and unfolding is as follows:

[0028] like Figure 5 and 6 As shown, loosen the fixing bolts between the pressure plate 3 and the limit support 5 that press the fender 4, so that the pressure plate 3 turns from a horizontal angle to a vertical angle under the action of gravity, and no longer applies a pressing force to the adjacent fender 4. Fender 4 is flipped upward according to the force set by the hinge center axis 13. Since the torque generated by the fender 4's own gravity is smaller than the damping torque generated by the hydraulic oil inside the hinge center axis 13, it can ensure that the fender 4 can be stopped at any angle within the 180° range of flipping up, without the need for additional support and fixation, ensuring that the maintenance personnel of the mobile system can safely perform maintenance.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
