As shown in fig. 1 to 3, a preferred embodiment of the present invention provides a length-adjustable bridge beam, which comprises two main beams 1 and at least one spliced beam 2 spliced between the two main beams 1, wherein the total length of the beam is adjusted by adjusting the number of the spliced beams 2.

In the embodiment, the number of the spliced beams 2 is adjusted according to actual construction needs, so that the length of the whole beam can be adjusted, and under a common condition, the structural size of the spliced beams 2 is consistent with that of the main beam 1, so that the stress conditions of the two structures are more consistent.

The adjacent main beam 1 and the end, close to each other, of the spliced beams 2 are detachably connected, and the adjacent two ends, close to each other, of the spliced beams 2 are detachably connected, so that the quick splicing and installation can be realized when the number of the spliced beams 2 is conveniently adjusted according to actual conditions, and the specific detachable connection mode is not limited.

The concrete detachable connection mode is provided below, the adjacent ends, close to each other, of the main cross beam 1 and the spliced beam 2 are respectively and vertically provided with a connecting plate 3 correspondingly, mounting holes are formed in the connecting plates 3, the main cross beam 1 and the spliced beam 2 are connected through a bolt structure, and the bolt structure is high in strength.

Considering in dismantling the concatenation in-process, because concatenation roof beam 2 weight is great, its one end that is dismantled earlier probably because the action of gravity can take place decurrent deformation, can lead to the inaccuracy of follow-up concatenation installation like this, consequently at the dismouting in-process, every set up at least one guiding mechanism 4 on the main beam 1, guide bar 6 passes adjacent in proper order main beam 1 guiding mechanism 4 on the concatenation roof beam 2, perhaps adjacent two guiding mechanism 4 on the concatenation roof beam 2 to realize the accurate location of whole dismouting process, avoid it to appear the deviation.

According to a preferred embodiment of the present invention, when a plurality of guiding mechanisms 4 are disposed on the main beam 1, the guiding mechanisms 4 are circumferentially spaced along the outer circumferential direction of the adjacent main beam 1.

A specific structure of the guide mechanism 4 is provided below, and the guide mechanism 4 includes a first guide plate 41 and a second guide plate 42, whose ends close to each other jointly form an accommodating cavity 43, so that the fixed end or the telescopic end of the hydraulic oil cylinder 5 respectively extends into the accommodating cavity 43. The ends of the first guide plate 41 and the second guide plate 42 close to each other are respectively recessed to form arc-shaped grooves, and the two arc-shaped grooves jointly form the accommodating cavity 43.

Specifically, the ends of the first guide plate 41 and the second guide plate 42, which are close to each other, are connected by a bolt structure.

According to a preferred embodiment of the present invention, the main beam 1 is provided with a reinforcing rib plate along the length direction thereof to enhance the rigidity of the whole body.
