[0020] Figure 1 , 2 3 shows that the horizontal support frame 3 is a U-shaped steel plate structure. The front ends of the two U-shaped side plates of the horizontal support frame 3 are respectively provided with through holes, and the connecting bolts 19 pass through the through holes and are fixedly connected to the connecting screw holes 16 on the bottom plate of the fixed support 2.

The side protection beam 5 is parallel to the U-shaped horizontal plate of the horizontal support frame 3. The two ends of the side protection beam 5 are respectively welded to the lower ends of the two side protection columns 4, and the side protection columns 4 can drive the side protection beam 5 to flip upward.

[0022] Figure 1 , 2 3 shows that in order to flip the rear side protection column 4 and the side protection beam 4 to maintain them in the flipped position, the device adopts the structure of a flip plug 6, a sliding rod 7, a reset spring 8 and a flip socket 9.

[0023] Figure 1 , 2 3 shows that the two flip plugs 6 are respectively located at the outer sides of the two ends of the U-shaped cross plate of the horizontal support frame 3, and the upper parts of the two flip plugs 6 are provided with sliding holes, and the two sliding rods 7 are respectively inserted into the sliding holes of the flip plugs 6, and the front ends of the two sliding rods 7 are respectively welded to the outer side surfaces of the U-shaped cross plate of the horizontal support frame 3, and the flip plugs 6 can slide along the sliding rods 7.

Under normal circumstances, the two return springs 8 keep the flip plug 6 at the free length position of the return springs 8; when the flip operation is required, the flip plug 6 is pulled outward, and the return spring 8 is pulled apart by external force; after the flip operation is completed, the return spring 8 returns the flip plug 6 to its original position by its own elastic force.

[0025] Figure 1 , 2 3 shows that two flip sockets 9 are welded to the lower ends of two side protection columns 4, respectively, and there are plug holes 13 in front of the two flip sockets 9, respectively, and L-shaped plug rods 14 are respectively provided at the lower parts of the two flip plug blocks 6, and the L-shaped plug rods 14 of the two flip plug blocks 6 are matched with the plug holes 13 of the two flip sockets 9. After the side protection beam 5 is flipped to a horizontal position, the plug rod 14 at the lower part of the flip plug block 6 is opposite to the plug hole 13 of the flip socket 9, and the plug rod 14 is inserted into the plug hole 13 to keep the side protection beam 5 in a horizontal position.

[0026] Figure 1 , 23 shows that a limit rod 10 is installed between the horizontal support frame 3 and the side protection column 4, and a connecting plate 11 is welded to the upper side of the two side protection columns 4, and a bolt connection hole 20 is provided on the connecting plate 11.

The function of the limit rod 10 is to keep the side protection structure in a normal position without shaking without flipping, so as to ensure the protection function of the side protection structure.

[0027] Figure 4 It is shown that the utility model can flip the side protection structure when the space under the frame 1 needs to be expanded during maintenance. The flipping process is as follows:

[0028] When flipping, first pull the flip plug block 6 outwards, the flip plug block 6 moves outwards along the sliding rod 7, and the L-shaped plug rod 14 at the bottom of the flip plug block 6 moves outwards accordingly, and the return spring 8 connected to the end face of the flip plug block 6 is also stretched outwards; at this time, the limiting bolt 22 at the front end of the limiting pull rod 10 connected between the side protection column 4 and the horizontal support frame 3 is taken out, and the side protection column 4 and the side protection beam 5 are flipped upwards. The flipping needs to be assisted by a jack when necessary; after the side protection column 4 and the side protection beam 5 are flipped into place, the sockets 13 of the two flip sockets 9 at the lower ends of the side protection column 4 are respectively opposite to the L-shaped plug rod 14 at the bottom of the flip plug block 6, and the flip plug block 6 is released.

[0029] After the maintenance work is completed, the flip plug block 6 is pulled outward, and the plug rod 14 at the bottom of the flip plug block 6 is withdrawn from the plug hole 13 of the flip socket 9. The side protection column 4 and the side protection beam 5 can rotate downward by gravity to restore the vertical position. The front ends of the two limit pull rods 10 are fixedly connected to the connecting plate 11 of the side protection column 4 using the limit bolts 22, so that the side protection column 4 and the side protection beam 5 are kept in the normal position without shaking.
