A track beam assembly and system according to embodiments of the present invention is described in detail below with reference to fig. 1-4.
As shown in fig. 1 to 4, the track beam splicing assembly 100 is used for splicing track beams, and the track beam splicing assembly 100 includes a base 1 and a lifting device 2. The lifting device 2 is connected with the base 1, and the lifting device 2 is arranged above the base 1. The lifting device 2 is used for placing the track beam so as to drive the track beam to move in the vertical direction.
In some embodiments, the track beam assembly 100 is primarily used for rail beam assembly. Before the track beam is formally assembled on line, the track beam needs to be pre-assembled, so that the linear precision of the track beam is ensured, and the condition that the track vehicle runs is influenced due to insufficient precision after the track beam is assembled on line is prevented. Thus, the track beam erection assembly 100 is employed. Subassembly 100 is assembled to track roof beam includes base 1 and elevating gear 2, and elevating gear 2 sets up in the top of base 1, and elevating gear 2 is connected with base 1 through bolt and nut. A rail beam can be placed on the lifting device 2. The rail beams are placed on the lifting device 2 to achieve assembly between the rail beams. And the lifting device 2 can move in the vertical direction and can drive the track beam to move in the vertical direction. Therefore, when the normal track beam needs to be pre-assembled, the lifting device 2 needs to be adjusted to the normal height; when the ultrahigh track beam needs to be pre-assembled, the lifting device 2 can be lifted, so that the ultrahigh track beam is pre-assembled. Here, it should be noted that the vertical direction is the direction of the z axis in the drawing.
Through the above description, the rail beam assembling assembly 100 can drive the rail beam to move in the vertical direction, and thus, the assembling of the straight beam and the super-high beam can be realized. And the track beam assembling component 100 is simple in structure, and the base 1 and the lifting device 2 are connected through bolts and nuts, so that the track beam assembling component is convenient to disassemble and assemble.
