In this embodiment, the storage portion 302 further includes a vertical column 332 vertically disposed on the bottom frame 306, the upper end of the vertical column 332 is provided with a fixed cross beam 333 and a removable cross beam 334, which are perpendicular to each other, the length direction of the fixed cross beam 333 is perpendicular to the extension direction of the isolation rod 315, and the length direction of the removable cross beam 334 is consistent with the extension direction of the isolation rod 315.

The upright posts 332 are four long strips with cross sections in L shapes, and the four upright posts 332 can limit the trench cover plate 100 in the storage cavity 305 horizontally.

The adjacent upright posts 332 connected with the movable cross beam 334 are respectively provided with a hinge shaft 335 and a clamping groove 336 with an upward opening, one end of the movable cross beam 334 is hinged on the hinge shaft 335 of one upright post 332, and the other end is clamped in the clamping groove 336 of the adjacent upright post 332 from top to bottom.

The fixed cross beams 333 and the movable cross beams 334 are arranged to effectively improve the stability of the overall structure of the storage frame 301, meanwhile, the four upright posts 332 are arranged to be angle steel, and the limitation of the trench cover plate 100 in the storage frame 301 in the horizontal direction can be effectively formed, so that the storage frame 301 is enabled to prevent the trench cover plate 100 from falling off during transportation.

When the storage frame is stored, the movable cross beam 334 is arranged on the adjacent upright post 332, when the operation is needed, the movable cross beam 334 is separated from the clamping groove 336, the limitation of the end of the movable cross beam 334 of the storage frame is removed, so that the lifting claw 403 can enter the storage frame 301 from top to bottom to grab the trench cover plate 100 at the lower part of the storage frame 301

Storage frame 301 is a plurality of and the bottom all is equipped with walking wheel 337, is equipped with connecting piece 338 between the adjacent storage frame 301, and connecting piece 338 includes setting up respectively in storage frame 301 along couple 339 and link 340 of the flexible direction both ends of isolation rod 315. The hooks 339 and the hanging rings 340 can realize the integral transportation of a plurality of storage frames 301 after being connected, and the channel cover plates 100 are heavy, so that a plurality of channel cover plates 100 are not suitable to be arranged on one storage frame 301, but the number of the channel cover plates 100 required in the operation is large, so that the mode of connecting a plurality of storage frames 301 together is adopted, and the transportation times of the storage frames 301 can be effectively reduced.

The both sides that just follow the flexible direction of spacer 315 on the lower terminal surface of bottom frame 306 all are equipped with side limiting plate 341, constitute the spacing portion of fork between the two side limiting plate 341, so that follow-up when installing trench cover 100, the fork 204 department that is located the apron installation car that storage frame 301 can be stable, and can fix a position storage frame 301 on the apron installation car, make storage frame 301 axis unanimous with apron installation car axis, so that follow-up lifting claw 403 snatchs lays or deposits, be convenient for the mechanized construction of trench cover 100. In summary, the above description is only a preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
