[0002] The high-voltage cable bridge channel is a cable structure on the bridge used to accommodate high-voltage cables and related accessories. For dual-use steel truss bridges for highway and railway, the high-voltage cable bridge channel is generally arranged along the entire length of the bridge below the highway bridge deck between the main truss and the secondary truss of the steel beam.

[0003] If a traditional crane is used to install a high-voltage cable bridge, the working space of the traditional crane is limited and the construction efficiency is low; if a construction platform is set up to install a high-voltage cable bridge, the setting up is difficult, the workload is large, and the construction efficiency is low.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The embodiment of the present invention provides a construction device for a high-voltage cable bridge channel, which can solve the technical problem of low construction efficiency in the existing high-voltage cable bridge channel construction.

[0040] See also Figure 1 , Figure 2 and Figure 3 As shown, a construction device for a high-voltage cable bridge channel includes: two rows of fixed components 1, two rails 2 and two pairs of movable lifting components 3.

[0041] Two rows of fixed components 1 are arranged longitudinally along the bridge and are spaced apart transversely along the bridge, and each fixed component 1 is connected to the steel beam 4 of the bridge. The present invention takes a road-rail dual-purpose steel truss bridge as an example, and the steel beam 4 of the bridge can be considered as the crossbeam of the steel truss bridge. Two tracks 2 are movably connected to the two rows of fixed components 1, respectively, and each track 2 can move along a corresponding row of fixed components 1. Two pairs of mobile lifting components 3 are used to lift the high-voltage cable bridge passage to be installed. The two pairs of mobile lifting components 3 are respectively arranged on two tracks 2 and can move along a corresponding track 2.

[0042] Specifically, see Figure 1 , Figures 6 to 8 As shown, two pairs of mobile lifting assemblies 3 are used to lift a segment of the high-voltage cable bridge channel, and the segment is installed on the steel beam 4 of the bridge. Two rails 2 and two pairs of mobile lifting assemblies 3 are moved longitudinally along the bridge to lift and install the next segment of the high-voltage cable bridge channel, until all segments 5 of the high-voltage cable bridge channel are installed on the steel beam 4 of the bridge.

[0043] Compared with the prior art, an embodiment of the present invention provides a construction device for a high-voltage cable bridge passage. By arranging two rows of fixed components 1, two rails 2 and two pairs of mobile lifting components 3, the two rails 2 and the two pairs of mobile lifting components 3 can move along the longitudinal direction of the bridge. At the same time, the two pairs of mobile lifting components 3 can lift the segments 5 of the high-voltage cable bridge passage. The construction device integrates the functions of movement and lifting. The construction is not limited by space and there is no need to set up a large number of construction platforms, which saves manpower and material resources and improves construction efficiency.

[0044] As an alternative embodiment, see Figure 4 and Figure 5As shown, each fixing assembly 1 includes: two fixing seats 11 , an upper plate 12 , two side plates 13 and two protrusions 14 .

[0045] The two fixing seats 11 are arranged at intervals, and their upper ends are connected to the steel beam 4 of the bridge. The upper plate 12 is connected to the lower end of the fixing seat 11, and the two side plates 13 are respectively located on both sides of the upper plate 12 and connected to the upper plate 12. Two protrusions 14 are respectively arranged on the inner sides of the two side plates 13, and a gap 15 is left between the protrusions 14 and the upper plate 12.

[0046] Further, see Figure 5 As shown, each track 2 is an I-beam, and its upper flange passes through the gap 15 of the corresponding row of fixing components 1 and is suspended on the protrusions 14. The track 2 can slide along the two protrusions 14. Preferably, the protrusions 14 are rollers to reduce the friction when the track 2 slides.

[0047] Further, see Figure 5 As shown, through holes are provided on the lower end of the fixing seat 11, the upper plate 12 and the track 2, and the lower end of the fixing seat 11, the upper plate 12 and the track 2 are detachably connected through the through holes. When the segment 5 of the high-voltage cable bridge channel is lifted, the fastener passes through the through holes to connect the track 2 with the fixing seat 11 and the upper plate 12, and the track 2 is locked.

[0048] As an alternative embodiment, see Figure 2 As shown, the mobile lifting assembly 3 is provided with two connected electric running mechanisms 31, and the running wheels of the two electric running mechanisms 31 are symmetrically suspended on the lower flange of the track 2. The mobile lifting assembly 3 is also provided with an electric winch 32 connected to the two electric running mechanisms 31. The electric running mechanism 31 can drive the mobile lifting assembly 3 to move along the track 2, and the electric winch 32 can lift the segment 5 of the high-voltage cable bridge channel, with a high degree of electrification and convenient use.

[0049] As an alternative embodiment, see Figure 1 As shown, the two ends of the two rails 2 are connected by a transverse connection 21, which facilitates the overall movement of the two rails 2 and can also limit the longitudinal position of the rails 2.

[0050] See also Figure 1 , Figures 6 to 8 As shown, an embodiment of the present invention also provides a construction method for a high-voltage cable bridge channel, comprising the following steps:

[0051] Each fixing assembly 1 of the two rows of fixing assemblies 1 is connected to the steel beam 4 of the bridge along the longitudinal direction of the bridge.

[0052] A track 2 is movably connected to each of the two rows of fixed components 1 , and a pair of movable lifting components 3 is provided on each of the two tracks 2 .

[0053] Use two pairs of mobile lifting assemblies 3 to lift a segment of the high-voltage cable bridge channel and install the segment on the steel beam 4 of the bridge. Move two rails 2 and two pairs of mobile lifting assemblies 3 along the longitudinal direction of the bridge to lift and install the next segment of the high-voltage cable bridge channel until all segments 5 of the high-voltage cable bridge channel are installed on the steel beam 4 of the bridge.

[0054] Specifically, when lifting and installing a section of the high-voltage cable bridge channel, the two rails 2 are locked with the two rows of fixed components 1. When the section is installed, the two rails 2 are unlocked from the two rows of fixed components 1, and the two rails 2 are moved longitudinally along the bridge, so that the two pairs of mobile lifting components 3 reach the lifting position of the next section. Preferably, see Figure 1 and Figure 6 As shown, the fixing assembly 1 at the rear end of the track 2 can be disassembled and installed at the front end of the track 2, so as to save the number of fixing assemblies 1 used as much as possible and reduce the construction cost.

[0055] Furthermore, when lifting and installing a segment of the high-voltage cable bridge channel, two pairs of movable lifting assemblies 3 are moved along the two rails 2 to adjust the longitudinal distance between the segment and the previous segment, so as to facilitate the installation and connection of two adjacent segments.
