Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, the shock absorption and buffering device for the road maintenance vehicle comprises a mounting plate 1, shock absorption rods 2 and a middle plate 3, wherein one surface of the middle plate 3 is connected with the mounting plate 1 through the shock absorption rods 2, the other surface of the middle plate is connected with a contact plate 5 through springs 4, an air bag assembly 6 and an air bag contact 6a are arranged on one side, close to the middle plate, of the mounting plate 1, and a safety rod 8 is arranged between the mounting plate 1 and the middle plate 3.

In order to carry out remote warning, a distance sensor 7a, an audible and visual alarm 7b and a control module are arranged on the side surface of the mounting plate 1, and the distance sensor 7a and the audible and visual alarm 7b are in communication connection with the control module; in this embodiment, the distance sensor 7a is an M30 ultrasonic distance measuring sensor, the audible and visual alarm 7b is a TL-90 rotary warning lamp, and the control module is a JKM-FCM-9G nodiffel control module.

In order to avoid the contact of the air bag from being touched by mistake, the safety rod 8 is of a toggle structure and comprises a front arm 8a and a rear arm 8b, the front arm 8a is rotatably connected with the middle plate 3, the rear arm 8b is rotatably connected with the mounting plate 1, and the front arm 8a is rotatably connected with the rear arm 8 b.

In order to avoid the locking of the safety rod 8, the rear arm 8b is provided with two fixing blocks 8d, the front arm 8a is fixedly connected with the safety rod 8c through a clamping tenon, and the safety rod 8c is positioned between the fixing blocks 8 d; in order to ensure that the safety rod 8 can be bent or broken when being violently impacted, the clamping tenon is made of brittle materials, and the material can be any one of gray cast iron and brittle plastics; gray cast iron was selected for this example.
