Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, the utility model discloses a damping device for special type haulage vehicle installs between special type haulage vehicle's traveling system and load-bearing platform for shake, the shock attenuation are inhaled to the impact vibrations that produce when the traveling system passes through the road surface. As shown in fig. 2 and 3, the installation of the shock absorbing device 1 for a special transportation vehicle on the special transportation vehicle is further illustrated.
Further, as shown in fig. 4-7, the damping device 1 for special transportation vehicles is mainly composed of a support base 11, a swing arm 12 and an airbag 15.
Wherein, the supporting seat 11 is used as a supporting component at the lower part and is fixed with the walking system.
The swing arm 12 is a vibration adjusting part; the middle part of the swing arm 12 is hinged on the supporting seat 11 through a lower pin shaft 13; one end of the swing arm 12 is hinged below the bearing platform through an upper pin shaft 14; the other end of the swing arm 12 is fixed with the air bag 15.
