Embodiment 1

[0029] Embodiment 1: In the construction condition in the tunnel, the construction in the tunnel is the most important working condition of the track laying operation. Under this working condition, tires are used throughout the whole process to avoid damage to the tunnel segments. The specific construction process is as follows: Before entering the tunnel section, the running span and height of the tires need to be adjusted to adapt to the width of the rail row and the height of the tunnel section. Under the action of the rail support legs 4 of the crane, the wheel support legs 3 are stretched and adjusted in order to adjust the height, and then the span of the whole machine is adjusted through the connecting beam 5 . After the adjustment is basically in place, drive the whole machine into the tunnel section, adjust the support angle of the wheel and wheel set 2 according to the adjusted height and position in the tunnel, so that the tires are positively pressed on the segment,...

Embodiment 2

[0030] Embodiment 2: In the construction condition of the platform section, the construction of the platform section is the most complicated operation condition of the track laying operation, and the wheel-rail is used for the whole process under this condition. The specific construction process is as follows: Before entering the platform section, the wheel-rail running span and height need to be adjusted to adapt to the width of the rail row and the height and width of the platform section. Under the action of the wheeled outriggers 3 of the crane, the wheeled outriggers 4 expand and contract in order to adjust the height, and then the telescopic connecting beam 5 adjusts the span of the whole machine, and then is supported on the temporary track. After the track wheel group 1 is supported in place, adjust the wheel leg 3 and the connecting beam 5 to avoid affecting the track laying operation of the platform section. Then the whole machine drives into the platform section for...

Abstract

The invention relates to a crane and a construction method, belongs to the field of engineering equipment, and especially relates to a rail-mounted and wheel-mounted combined type tunnel track-laying crane and a construction method thereof. The crane provided by the invention comprises a rail-mounted wheel set and a wheel-mounted wheel set, wherein the top of the rail-mounted wheel set is movably provided with a connecting beam; and both ends of the connecting beam are provided with support-angle-adjustable wheel-mounted wheel set. Therefore, the invention has the following advantages: the design structure is simple; by the double walking modes of rail walking and wheel walking, the problem that different cross-sections of tunnel construction cannot be dual-purpose can be solved; and different walking modes can be rapidly switched, thus improving production efficiency and reducing damage to duct pieces.

Description

technical field [0001] The invention relates to a crane and a construction method, which belong to the field of engineering equipment, and in particular to a tunnel track-laying crane and a construction method of a combined track and wheel row. Background technique [0002] The subway track laying construction environment is diverse, there are many different construction sections, and the equipment limits are different, including: screen door section, island platform section, rectangular platform section, civil air defense door section, and circular tunnel section. At present, the construction of various types of subway track-laying gantry cranes generally adopts the whole process of laying temporary running tracks (various gauges), first using expansion bolts to fix the bottom plate of the steel pier on the platform and the bottom plate of the tunnel, and adjusting the height of the steel pier to meet the construction requirements position, the upper plate of the steel pier...
