The invention discloses a rail clamping device of a ship crane, which relates to the technical field of the manufacture of crane accessories. The rail clamping device comprises a stander with a track, an upper pressing and clamping block which is arranged above the track and a lower pressing and clamping block which is arranged below the track, wherein the upper pressing and clamping block consists of an upper outer spherical clamping block and an upper inner spherical pressing block which is arranged on the upper outer spherical clamping block; a first hydraulic cylinder is arranged on the stander above the track, and a piston rod of the first hydraulic cylinder penetrates through the upper inner spherical pressing block to be connected with the outer spherical clamping block; the lower pressing and clamping block consists of a lower outer spherical clamping block and a lower inner spherical pressing block which is arranged on the lower outer spherical clamping block; a second hydraulic cylinder is arranged on the stander below the track, and a piston rod of the second hydraulic cylinder penetrates through the lower inner spherical pressing block to be connected with the lower outer spherical clamping block. Compared with the prior art, the rail clamping device is reliable in performance and suitable for a working ship to work in an environment likely to be suffered from the wind and wave attack.
Description
Technical field [0001] The invention relates to the technical field of crane parts manufacturing, in particular to a rail clamp for a rail crane of an engineering ship. Background technique [0002] Rail clamps are mainly used for wind-proof and anti-skid of rail-mounted cranes. When rail-mounted cranes are stopped or parked, rail clamps are used to clamp the rail by applying external force to prevent the crane from sliding due to changes in the external environment. Commonly used rail clamps are mainly divided into manual rail clamps and electric rail clamps according to the form of power. However, these rail clamps are not suitable for environments where engineering ships are susceptible to wind and waves due to their complicated structure, many installation procedures, and time-consuming and laborious operation. Summary of the invention [0003] The problem solved by the present invention is to provide a ship crane rail clamp with reliable performance and good applicability. ...
