The utility model discloses a wellhead device with shock-proof and sound-proof functions, which comprises:

the well ring is used for being arranged on a well head;

the well lid is arranged on the well ring in an openable and closable manner and is used for sealing a well mouth;

elastic support piece, elastic support piece set up between walling crib and well lid.

Specifically, set up elastic support piece between well lid and walling crib, when the vehicle passes through, elastic support piece can be compressed, reduce vibrations, and certain supporting role still has, keep sufficient structural rigidity between well lid and the walling crib, avoid well lid and walling crib direct collision, and can reset by oneself after the vehicle passes through, make the well lid device be in normal use state all the time, reduce the friction of well lid and walling crib, reduce the spoilage, prevent that the well lid from warping, reduce cost of maintenance.

As an alternative scheme, the elastic supporting piece comprises a pressure spring, the pressure spring is connected between the well lid and the well ring, and a rubber layer wraps the surface of the pressure spring.

Specifically, the pressure spring is the helical spring who bears axial pressure to have good support and reset ability, in this scheme, in order to make well lid and walling crib keep parallel and place steadily, wind the both ends of pressure spring flat or grind the flat.
