Description
Technical Field
[0001] The utility model belongs to the field of bridge construction equipment, and particularly relates to a crawler crane traveling support device for an open lattice steel beam. Background Art
[0002] The structural form of the arch bridge deck system is generally an open lattice steel beam plus a concrete bridge deck. The main longitudinal beams of the open lattice steel beam are steel box girder sections on both sides. Between the two main longitudinal beams are frame-type small longitudinal beams and cross beams arranged longitudinally and transversely. The top surface of the frame-type small longitudinal beams and cross beams is provided with a concrete bridge deck. Before the installation of the concrete bridge deck, the deck system only consists of the lattice steel beam composed of the main longitudinal beams, small longitudinal beams and cross beams. This frame structure has no top plate and bottom plate and is open, so it is called an open lattice steel beam.
[0003] Different from the steel box girder bridge, when constructing on the open lattice steel beam of the arch bridge, due to the open form of this frame structure, it is difficult for the crawler crane to get on the bridge and it is inconvenient to move. And because the open lattice steel beam is often installed by the method of piecemeal hoisting, the number of components is large, and the hoisting range of the crawler crane is limited, which will affect the installation efficiency. Therefore, there is an urgent need to provide a crawler crane traveling support device for construction on the open lattice steel beam. Summary of the Utility Model

The technical features in each embodiment of the present utility model can be combined correspondingly without conflict.
[0028] In the description of the present utility model, it should be understood that the terms "first" and "second" are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.
[0029] As a preferred embodiment of the specific implementation manner of the present utility model, this embodiment provides a crawler crane traveling support device for an open lattice steel beam.

[0030] Such as Figure 1As shown in the figure, in this embodiment, each support component includes two support longitudinal beams 1, three support cross beams 2, and two support plates 4. The two support longitudinal beams 1 are arranged parallel to each other left and right, and the support cross beams 2 are vertically fixed between the two support longitudinal beams 1. In this embodiment, the three support cross beams 2 are fixedly spaced along the longitudinal direction of the support longitudinal beam 1. The two support plates 4 are respectively fixed on the upper surface of the support longitudinal beam 1 to serve as the traveling surface of the crawler crane. In this embodiment, the support plate 4 is a steel plate and is fixed on the upper surface of the support longitudinal beam 1 by welding.
[0031] As Figure 2 shown, each support longitudinal beam 1 is composed of three parallel I-beams, and the I-beams are connected by cross braces 3. The cross braces 3 are perpendicular to the I-beams, and the cross braces 3 are arranged at intervals along the longitudinal direction of the support longitudinal beam 1.
[0032] It should be noted that in this embodiment, each support longitudinal beam 1 uses three I-beams and three support cross beams 2 are provided. Those skilled in the art can also use more I-beams to form the support longitudinal beam 1 or set more support cross beams 2 according to the actual working conditions to improve the compressive strength of the support component.
[0033] In the device provided by the present utility model, as Figure 2 shown, a third socket 1-1 for inserting a pin 7 is opened at the front end of the support longitudinal beam 1, and a fourth socket 1-2 for inserting a pin 7 is opened at the rear end of the support longitudinal beam 1.

The insertion and connection method is as Figure 3 shown.
[0036] In this embodiment, two groups of inner and outer first sockets 5-1 are opened on the rectangular steel pipe of each first end interface 5, and two groups of inner and outer second sockets 6-1 are also opened on the rectangular steel pipe of each second end interface 6.

[0037] In this embodiment, the support cross beam 2 is made of double I-shaped steel, and the cross brace 3 is made of channel steel. It should be noted that those skilled in the art can select other sections according to the actual working conditions. For example, the support cross beam 2 can also be made of H-shaped steel, and the cross brace 3 can also be made of angle steel, I-shaped steel or square steel pipe, etc.
[0038] In order to limit the traveling direction of the crawler crane on the support component, several limit plates 8 are also fixed on the support plate 4 in this embodiment, as Figure 1 shown. The limit plates 8 are fixed on the outermost sides of the two support plates 4. The limit plates 8 can be made of sections such as channel steel, angle steel, I-shaped steel or H-shaped steel, and are fixed on the support plate 4 by welding.
[0039] The following provides the process of hoisting on the open lattice steel beam using the above crawler crane traveling support device:
[0040] S1. Hoist the two support components onto the open lattice steel beam and connect them with pins to form a crawler crane traveling support device.
