Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 6, the present invention provides a technical solution:

a novel chassis structure is shown in figures 1 to 4 and comprises a main beam 1, two side faces of the main beam 1 are provided with side beams 2, and four wheels and a belt assembly 3 are arranged on the side beams 2. Connecting groove 101 has all been seted up to the both sides face of girder 1, and side roof beam 2 corresponds a side fixedly connected with flange 201 of connecting groove 101, and flange 201 inserts in connecting groove 101 and can dismantle the connection through damper 4. Through damper 4 who sets up, effectual vibrations to equipment have played the cushioning effect, all play positive effect to reducing equipment fault rate and increase of service life.

As shown in fig. 5 and 6, the damping member 4 includes a threaded rod 401, and first connection holes 102 are formed on both sides of the upper and lower ends of the connection groove 101. The two sides of the top end of the connecting flange 201 are provided with second connecting holes 202, and the threaded rod 401 penetrates through the first connecting hole 102 and the second connecting holes 202. An upper elastic element 402 and a lower elastic element 403 are movably connected to the outer side surface of the threaded rod 401, and the upper elastic element 402 and the lower elastic element 403 respectively abut against the upper end and the lower end inside the connecting groove 101 and clamp the connecting flange 201 in the middle. The upper elastic member 402 and the lower elastic member 403 cooperate to effectively cushion the connecting flange 201 and the side member 2. The top end of the threaded rod 401 is fixedly connected with an upper nut 405, the bottom end of the threaded rod 401 is fixedly connected with a lower nut 404, and the upper nut 405 and the lower nut 404 are respectively in contact with the upper end face and the lower end face of the main beam 1.
