Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to an auxiliary supporting device and a walking device of a gantry. Background Art

[0002] Figure 1 It is a schematic diagram of the structure of the gantry and the supporting machine in the prior art. Figure 1 As shown, the TRD method refers to the underground continuous mixing wall method of equal thickness cement soil. When assembling the TRD method machine, the gantry 31 needs to be supported by the support machine 32 to stand up the gantry 31. The support machine 32 is inclined relative to the gantry 31, one end of the support machine 32 is fixed on the gantry 31, and the other end of the support machine 32 is fixed on the main platform 33 of the walking device. When installing the gantry 31, the gantry 31 needs to be hoisted by the first hoisting device. After the gantry 31 is installed, since the gantry 31 itself does not have a supporting and fixing structure, the first hoisting device needs to assist in hoisting the gantry 31 to prevent it from tilting and falling and causing a safety accident. At this time, if the support machine 32 is to be installed to support the gantry 31, the second hoisting device needs to be used to hoist the support machine 32 to assist the installation between the support machine 32 and the gantry 31. Therefore, two hoisting devices are needed to install the gantry 31, and the TRD construction method machine equipment needs to be reassembled every time it arrives at the construction site, and the number of disassembly and assembly is frequent, resulting in an economic waste of hoisting costs. In addition, since two hoisting devices are needed, the size of the site is required to be high. Utility Model Content
