Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

Fig. 1 shows an implementation form according to the present invention, which includes: stand 1, crossbeam, 2, slide rail 3 and ceiling 4, stand 1 distributes in the railway line both sides that need protect parallelly, crossbeam 2 along the railway extending direction install in the top of stand 1, the length of crossbeam 2 equals the length that stand 1 distributes along the railway line, the ascending slide rail 3 of opening is installed along its length direction in the top of crossbeam 2, ceiling 4 install in the upper end of slide rail 3, just the bottom of ceiling 4 is equipped with four at least sliders 5, slider 5 supports ceiling 4, and can follow slide rail 3 takes ceiling 4 freely slides.

According to the technical scheme, various materials of the protective shed frame can be prefabricated and processed in the early stage and then transported to a construction site for installation, during installation, the plurality of upright columns 1 are installed on two sides of a railway line needing to be protected in parallel, the cross beam 2 is installed at the top ends of the upright columns 1 along the railway extending direction, the slide rails 3 are installed at the top ends of the cross beams 2, the ceiling 4 is hoisted to the slide rails 3 by a crane and then moved to a specified position along the slide rails 3, and after the ceiling 4 is moved along the slide rails 3 until all railway lines needing to be protected are covered, the protective shed frame installation across the railway line is completed. When the roof is dismounted, the ceiling 4 is firstly slid to dismount, and then the sliding rails 3, the cross beams 2 and the upright posts 1 are sequentially dismounted.

Fig. 2 shows an implementation form of the present invention, wherein a first through hole 51 is provided on the slider 5, a plurality of pairs of corresponding second through holes 31 are drilled equidistantly on two side walls of the slide rail 3, and the first through hole 51 and the second through holes 31 are connected by a connecting rod 6. When in use, the positions of the second through holes 31 can be arranged according to a fixed distance, the sizes of the first through holes and the second through holes can be slightly larger than that of steel rods used in construction, and steel rods left on site can be used for sequentially penetrating through the second through holes, the first through holes and the second through holes in construction to be connected and fixed; the first through hole and the first through hole can also be threaded holes, and after alignment, the screw rod is used for connection and fixation.

One implementation manner of the slide rail 3 in the above scheme is as follows: rubber layers are arranged at positions corresponding to the sliding blocks 5 in the two side walls of the sliding rail 3. The rubber layer can be tightly attached to the sliding block 5, so that the sliding block 5 is prevented from moving before the connecting rod 6 is used, and the sliding block 5 is prevented from moving in the width direction of the sliding rail 3 after the connecting rod is fixedly connected.
