A traveling device for a trackless gantry crane

Abstract

The invention relates to a walking device for a rail-free gate type crane. The walking device for the rail-free gate type crane is characterized in that the walking device comprises a supporting rod (4), an adjusting seat (34) is connected to the lower side of the supporting rod (4) through a first hydraulic cylinder (17), the adjusting seat (34) is connected with a vehicle wheel frame (36) through a first articulated shaft (35), the lower side of the vehicle wheel frame (36) is connected with a set of vehicle wheels (37), and a driving device (38) is mounted on one of the vehicle wheels (37). The walking device for the rail-free gate type crane has the advantages that the walking device is suitable for walking on cross sections under various working conditions, can meet requirements for walking of various fracture surfaces of various sections, not only can walk on plane roads, but also can walk on circular arc oblique planes and sloped oblique planes; the walking device can conduct steering on the cross sections under the various working conditions, can meet requirements for steering of the various fracture surfaces of the various sections in the walking process, and can conduct steering on the plane roads, the circular arc oblique planes and the sloped oblique planes; and the walking device can make transverse movement and deflection in the center of a suspended load under the various working conditions, and can meet requirements for transverse displacement of curve section routes.

Description

technical field [0001] The invention relates to a track laying equipment, in particular to a traveling device for a trackless gantry crane. Background technique [0002] In recent years, my country has gradually become the country with the most railway operating mileage in the world. In order to ensure the high-speed operation of trains, the track structure is required to have a strong integrity. Once the foundation is greatly deformed or the force transmission parts of the track are damaged, the track structure It is difficult to guarantee the stability and smoothness of the train, which may lead to the speed limit of the train, or cause a safety accident. In practical application, during the track construction of railways and subway tunnels, track slabs, sleepers, formwork, rail rows, steel rails and turnouts all need to be hoisted, and track structural components may be damaged during service, and track slabs or Concrete base plate is cracked, damaged or broken, high-spee...
