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 accessory manufacturing, in particular to a rail clamp used for a rail crane of an engineering ship. Background technique [0002] The rail clamp is mainly used for the windproof and anti-skid of the rail crane. When the rail crane is stopped or parked, the rail clamp is used to clamp the rail by applying an 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 power form. However, these rail clamps are not suitable for the environment where engineering ships are easily attacked by wind and waves due to their complex structure, many installation procedures, and time-consuming and laborious operations. Contents of the invention [0003] The problem to be solved by the invention is to provide a rail gripper for a marine crane with reliable performance...
