A drilling rig walking device

Abstract

A drill traveling device comprises oil cylinders, a supporting beam, fixing beams and moving assemblies, wherein oil cylinder fixing devices are fixedly connected with the upper part of the supporting beam; headframes are arranged at the upper parts of the oil cylinder fixing devices and fixedly connected with the supporting beam; the oil cylinder fixing devices are connected with the oil cylinders; the oil cylinders are vertically placed and provided with piston rods; the moving assemblies are arranged at the lower parts of the piston rods, and comprise lower connecting seats and traveling beams; the traveling beams are arranged below and fixedly connected with the lower connecting seats; traveling wheels are arranged at the lower parts of the traveling beams and connected with driving devices; the fixing beams are arranged on both the left and right sides of the lower part of the supporting beam; the traveling beams are positioned between the two groups of fixing beams; through extension and retraction of the oil cylinders, a drill frame and a wellhead surface foundation can be quickly combined or separated from each other; the oil cylinders are straightened by guide cylinders, so that the force transmission direction of the oil cylinders can be stabilized, and the true positions of the drill frame and the wellhead surface foundation can be guaranteed; and through arrangement of the fixing beams, a reliable bearing foundation for thousands of tons of weight of a drill can be ensured.

Description

technical field [0001] The invention relates to the technical field of shaft drilling rigs, in particular to a drilling rig traveling device. Background technique [0002] In the construction of shaft drilling rigs, the assembly speed of shaft drilling rigs entering the site and the evacuation speed of exiting the site are a key factor affecting the entire construction period. In the previous shaft drilling rigs, most of the drilling rigs used a fixed derrick structure. This structure was difficult to install during use, and the later disassembly period was long, which took a lot of time. At this stage, the movement of the shaft drilling rig is replaced by a walking mechanism, but the derrick is in place. The fast fixation after the drill and the fast breakaway during evacuation have become important factors restricting the working efficiency of the drilling rig. Contents of the invention [0003] The purpose of the present invention is to provide a drilling rig traveling...
