The invention discloses an anti-derailing rail clamping device for a portal crane. The anti-derailing rail clamping device comprises two clamping pincers, a support is movably connected to the upper ends of the two clamping pincers, a protection barrel is connected to the lower end of the support through an installing plate, an interlocking switch is arranged inside the protection barrel, a firsthydraulic cylinder is fixed to the top end of one clamping pincer, the output end of the first hydraulic cylinder is fixedly connected with the top end of the other clamping pincer through a connecting piece, rotating shafts are connected to the lower ends of the two clamping pincers, pincer forks are arranged at the bottom ends of the two clamping pincers, and meanwhile, anti-derailing clamps areinstalled at the lower ends of the two clamping pincers. The anti-derailing rail clamping device is provided with the clamping pincers, the protection barrel, the interlocking switch, the first hydraulic cylinder, a spring, the anti-derailing clamps, a strut, a protection shell, a second hydraulic cylinder, a limiting plate and a protrusion, the problems that at this stage, an anti-derailing railclamping device for the crane is not high in automatic degree in use, manual adjustment is needed, and the using risk is high are solved.
Description
technical field [0001] The invention relates to the technical field of crane equipment, in particular to an anti-derailment rail clamp for a gantry crane. Background technique [0002] At present, a crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range, also known as a crane, aerial crane, and crane. Gantry crane is a deformation of bridge crane, also called gantry crane. It is mainly used for loading and unloading operations of outdoor cargo yards, stockyard cargoes, and bulk cargoes. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in port freight yards. When the crane is in use, a rail clamp is required. The rail clamp is a crane safety device that prevents the outdoor crane from sliding along the track under the action of strong wind. Usually, the clamp connected with the bottom structure ...
