Embodiment 1

[0043] Such as Figure 1-Figure 13 As shown, a railway subgrade assembled cable trough includes trough body segments, each of which includes a bottom plate 1, two side plates 2 and a number of cross arms 3, and the inner walls of the side plates 2 are provided with clips Buckle groove 4, the bottom plate 1 is provided with a card slot 11, the side plate 2 is connected with the bottom plate 1 through the card slot 11, and the cross arm 3 is locked with the side plate 2 through the buckle groove 4 buckle connection.

[0044] In this embodiment of a railway embankment assembly type cable trough, a card slot 11 is provided on the bottom plate 1 corresponding to the position of the side plate 2. The card slot 11 includes two vertically parallel vertical plates 111, and the side plate 2 can extend into the two vertical plates. In the gap between the plates 111, the buckle connection between the side plate 2 and the bottom plate 1 is realized, and the inner wall of the side plate 2 ...

Embodiment 2

[0052] Such as Figure 1-Figure 13 As shown, the railway subgrade assembled cable trough of this embodiment has the same structure as that of Embodiment 1, except that the adjacent cover plates 9 are buckled and connected.

[0053] In this embodiment of a railway subgrade assembled cable trough, the top surface of the cover plate 9 is provided with a connection groove 1 92 along the transverse direction of the cable trough, and the bottom surface of the cover plate 9 is provided with a connection trough 2 93 along the transverse direction of the cable trough. The first connection groove 92 and the second connection groove 93 of the provided cover plate 9 are snap-connected, so as to realize the snap-fit ​​connection of adjacent cover plates 9 .

[0054] Specifically, on the same cover plate 9, the first connecting groove 92 and the second connecting groove 93 are sequentially arranged along the traveling direction of the train, and the first connecting groove 92 and the second...

Embodiment 3

[0058] Such as Figure 1-Figure 13 As shown, a railway subgrade assembly type cable trough of this embodiment has the same structure as that of embodiment 2, the difference is that the buckle groove 4 is continuously arranged along the extending direction of the cable trough, and the side plate 2 is provided with a The buckle slot 4 is described above.

[0059] In this embodiment of an assembled cable trough for a railway subgrade, the buckle trough 4 is formed by the inner wall of the side plate 2 continuously protruding into the cable trough and extending upward, which can strengthen the side plate 2 and can be installed on the side according to the actual situation. A plurality of buckle grooves 4 are arranged parallel to the inner wall of the plate 2, which reserves a place for installing the cross arm 3, and improves the compressive strength of the side plate 2 itself. At the same time, because the buckle grooves 4 are continuously arranged, it can Slide the cross arm 3 ...

Abstract

The invention belongs to the technical field of cable trough equipment and relates to a railroad bed assembly type cable trough. The railroad bed assembly type cable trough comprises a plurality of trough body sections; each trough body section comprises a bottom plate and side plates arranged on the two sides of the bottom plate, wherein the bottom plate and the side plates are connected in a buckled mode; and the railroad bed assembly type cable trough further comprises a plurality of cross arms; the cross arms are connected with buckle grooves formed in the inner walls of the side plates in a buckled mode. Segmental factory prefabrication The manufacturing, transporting and installing cost is reduced through, meanwhile, the environmental adaptability of the cable trough can be improved by adjusting the size or shape of the bottom plate, meanwhile, the supporting strength of side walls can be adjusted according to transverse side pressure, so that the durability of the cable trough can be improved, and the service life of the cable trough can be prolonged; the cross arms can be used for bearing a supporting component of a cable, so that an angle steel bracket for supporting the cable does not need to be independently arranged in the cable trough, the preparation cost, the installation cost and the use cost of the cable trough are reduced; and only each component needs to be independently replaced during later maintenance and repair, and the maintenance and repair cost of the cable trough is low.

Description

technical field [0001] The invention relates to the technical field of cable trough equipment, in particular to a railway subgrade assembled cable trough. Background technique [0002] Traditional railway subgrade cable troughs mostly use concrete cast-in-place troughs or concrete prefabricated troughs. The trough body is an integral trough structure, and the top is closed with a cover plate. The inner wall of the trough is fixed with expansion bolts to set angle steel brackets to support cables. The traditional railway subgrade cable trough has complex construction technology, low production efficiency and poor appearance, and is easily damaged and inconvenient to maintain in the later stage. [0003] Chinese invention patent application CN105778454A discloses a SMC public railway cable trough, which refers to a prefabricated cable trough made of SMC materials, including a trough body and a convex beam that is arranged in the middle of the inner side of the trough body and ...
