Embodiment

[0044] The track laying machine applied in this embodiment is composed of three parts: guide sleeve, traverse mechanism assembly and guide column type upper beam, and its structure is described in turn:

[0045] Guide sleeve such as Figure 5 , 6 , 7, it is mainly composed of a cover plate 51, a bottom plate 52, a web 53, a reinforcing plate 54, and ribs 55, 56. The guide sleeve is a hollow cuboid structure with missing corners, and the cuboid is an upper narrow Lower wide structure, cover plate 51 is positioned at the top of cuboid, base plate 52 is positioned at the bottom of cuboid, and web 53 is positioned at the cavity interior of cuboid and vertical bottom plate 52 is placed, and the side of guide sleeve is also provided with ribs 55,56.

[0046] As shown in Figure 3(a) and Figure 3(b), the traversing mechanism assembly mainly consists of a traversing support 31, a coupling 32, a bearing seat 33, a traversing lead screw 34, a traversing nut 35, a traversing Shift guide...

Abstract

The invention belongs to the technical field of subway track-laying engineering machinery, and particularly relates to a host machine of a track-laying machine improved based on a replacement structure, and an assembly method thereof. The assembly method for the host machine of the track-laying machine comprises the following steps: step (1), a boom of the track-laying machine is connected with a first rigid portal and a second rigid portal; step (2), a guide sleeve type left framework and a guide sleeve type right framework are assembled on the boom, and the gaps between four guide sleeves of the guide sleeve type left framework and the guide sleeve type right framework and a sill beam are consistent; step (3), after the guide sleeves are assembled, a guide column type upper cross beam is assembled; step (4), upper cross beam guide columns and upper cross beam guide column lengthening sections are assembled through fastening blots; and step (5), when the upper cross beam guide columns are assembled with an upper cross beam hoist and sheave block sill beam, the connected parts of two ends are positioned in the same horizontal plane. The span of the track-laying machine is adjusted by adopting the motor screw driving principle, meanwhile, the electric hoists originally installed at two ends of the vertical beam are installed above the vertical beam, so that the demands of different spans in the subway construction are met, the potential safety hazard during the span adjusting process of the assembly type track-laying machine is reduced, the adjustment time is saved, and the labor intensity of workers is reduced.

Description

[technical field] [0001] The invention belongs to the technical field of subway track-laying engineering machinery, and in particular relates to a track-laying machine host and an assembly method for adjusting the construction distance of the track-laying machine by using a motor screw mechanism. [Background technique] [0002] In the current subway track laying construction process, the upper beam of the track laying machine used is an assembled structure, and its span size can only be adjusted in 3.8m, 3.55m, 3.1m, 2.85m, 2.6m, and 1.508m. After the connection assembly between the upper beam and the beam needs to be disassembled, the shape-carrying mechanisms on both sides should be adjusted separately and reassembled. [0003] For example, the domestic patent CN201933411U discloses a railway paving machine, which includes a machine arm, a suspension column, a suspension beam crane, a suspension rail trolley, a car body, a joist trolley, and a bogie; There are three verti...
