[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1-4As shown, a trough-type cable bridge comprises a plurality of steel trough members 1 which are sequentially plugged in and assembled end to end, and a covering member 2 covering the joint between every two steel trough members 1;

[0025] A reinforcing plate 3 is provided at the rear end of the steel channel member 1. The reinforcing plate 3 extends to the connecting parts 31 formed on both sides of the steel channel member 1 and is fixed to the side walls of the cover member 2 on opposite sides with centrally arranged extension ears 9 through bolts.

[0026] Further, combined with Figure 2 It can be seen that the inner wall of the head end of the steel channel member 1 is provided with a protrusion 4, and a plug-in cavity 5 is formed between the protrusion 4 and the inner wall of the steel channel member 1; and the tail end of the steel channel member 1 is provided with an embedded portion 6 that is plugged into the plug-in cavity 5. The plug-in cavity 5 and the embedded portion 6 cooperate to achieve the above-mentioned head-to-tail plug-in combination.

[0027] Furthermore, the portion of the reinforcing plate 3 extending out of the tail end along the axial direction of the steel channel member 1 is the supporting portion 7. Therefore, for two steel channel members 1 assembled end to end, the head end of the steel channel member 1 of the rear section will inevitably sit on the supporting portion 7 of the tail end of the steel channel member 1 of the previous section.

[0028] In the above technology, multiple steel channel members 1 are assembled by plug-in, and then the joint between two adjacent steel channel members 1 is covered by the covering member 2, and then the extended ear 9 on the side wall of the covering member 2 corresponding to the joint between the two adjacent steel channel members 1 and the connecting portion 31 extending to the outside formed by the reinforcing plate 3 at the rear end of the steel channel member 1 are fixed by bolts, which reduces the use of bolts, improves the convenience of construction and installation, and at the same time ensures the integrity after installation.

[0029] As an embodiment further provided by the utility model, rectangular grooves 11 are provided on the outer walls of the steel channel member 1 on opposite sides;

[0030] It also includes a hollow-bent special-shaped plate 8, which is divided into a constriction end 81 and a U-shaped portion 82 according to the structure, and the constriction end 81 is arranged on the end of the rectangular groove 11;

[0031] The outer wall of the U-shaped portion 82 extends to the inside of the insertion cavity 5 and the outside of the steel channel member 1 respectively.

[0032] Furthermore, the U-shaped portion 82 has two arc-shaped protrusions 83 on one side facing the insertion cavity 5 , and the radius of the two arc-shaped protrusions 83 increases from the constriction end 81 toward the bottom of the U-shaped portion 82 .

[0033] Specifically, when the cover 2 covers the joint between two adjacent steel channel members 1, the cover 2 drives the inner diameter of the U-shaped portion 82 to shrink during the sliding process, so that the arc-shaped protrusion 83 is deformed due to squeezing the side wall of the embedded portion 6, thereby forming a pin fixation.

[0034] As another embodiment further provided by the present invention, an obliquely arranged push piece 21 is symmetrically provided on the inner top of the cover 2 , and an end of the push piece 21 contacts the outer wall of the protrusion 4 .

[0035] Specifically, in the above embodiment, when the cover member 2 covers the joint between two adjacent steel channel members 1, the end of the push member 21 is pressed away from the side wall of the cover member 2 as it is inserted, thereby forming a clamping effect and providing a re-fixing effect.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
