Adjustable rail compaction device for crane trolley

The invention discloses a device for compacting rails for driving of a crane trolley, and belongs to the technical field of crane equipment. The device comprises a base (17), a driving part (2), an intermediate part (3), a driven part (4), compaction plates (5) and a base upright post (21), wherein the base (17), the driving part (2), the intermediate part (3) and the driven part (4) are connectedthrough a connecting shaft I (22), a connecting shaft II (23), a connecting shaft III (24) and a connecting shaft IV (25); one end of the driving part (2) is fixed to the base upright post (21); thecompaction plates (5) are fixedly jointed on the driven part (4). According to the device disclosed by the invention, by utilizing a mechanical dead point principle in a planar connecting rod mechanism, compaction of the traveling rails of the crane is realized; after the rails are compacted by the rail compaction device, the compaction device is located at the mechanical dead point, and the device still can keep a compact
