Locking and buffering device for trestle connection between ocean platforms

The utility model discloses a locking buffer device for trestle connection between ocean platforms, which comprises a buffer device, a trestle support, a locking device and a positioning plate, the buffer device is respectively composed of a trestle cylindrical support arc-shaped plate, a bottom plate and a support structure plate, the bottom of the buffer device is fixedly connected with the support structure plate, and the support structure plate is fixedly connected with the bottom of the buffer device. The supporting structure plates are symmetrically distributed. By means of the upper stainless steel protection plate, the lower stainless steel protection plate and the bottom plate, impact of platform vibration and stormy waves is considered, in order to reduce friction caused by left-right displacement of the trestle and impact caused by up-down displacement, stainless steel welding rods are selected for welding, and meanwhile a layer of Teflon plate is adhered to the bottom of stainless steel after weld
