When the portable multifunctional movable fireproof bridge is required to be used, the U-shaped frame 1 is pushed to drive the device to move, the wheels 3 are in contact with the ground and rotate, then people push the device to a place to be used, after the place is reached, the U-shaped frame 1 stops being pushed, the second nut 17 is reversely rotated to enable the second nut 17 to be separated from the second screw 16, after the second screw 16 is separated, the second screw 16 is reversely rotated to enable the second screw 16 to be separated from the second rotary rod 10 and the first rotary rod 8, then people turn the upper U-shaped frame 1 downwards, the upper U-shaped frame 1 drives the upper U-shaped plate 6, the second rotary rod 10 and the second rotary rod 10 to turn downwards, so that the upper U-shaped plate 6 is separated from the lower U-shaped plate 6, when the upper U-shaped frame 1 and the U-shaped plate 6 are turned to be in the same horizontal plane with the lower U-shaped frame 1, then, the second screw 16 can be aligned with the second rotary rod 10 and the first rotary rod 8, after the alignment is completed, the second screw 16 is rotated, so that the second screw 16 fixes the second rotary rod 10 and the first rotary rod 8, then the second nut 17 is aligned with the second screw 16, the second nut 17 is rotated, so that the second nut 17 fixes the second screw 16, after the fixation is completed, the U-shaped frame 1 on the right side can be pushed to the left side, the U-shaped frame 1 on the right side drives the U-shaped plate 6 and the first L-shaped plate 7 to move to the left side along the U-shaped plate 6, when the U-shaped frame 1 on the right side drives the U-shaped plate 6 to move to the left side to the limit, one can repeat the above steps of reversely rotating the second screw 16 and the second nut 17, and then pull the two U-shaped plates 6 to the side far away from each other, and then the two U-shaped plates 6 can drive the two first clamping rods 12 on the same side to pull to the side far away from each other along the fixing rods 11 on the same side, so that the first clamping bar 12 is separated from the fixed bar 11, then people can take the two U-shaped plates 6 out of the two U-shaped frames 1, after taking out, people can put in the cables to be hidden, after putting, the two U-shaped plates 6 move to one side close to each other, the two U-shaped plates 6 drive the two first clamping bars 12 on the same side to move to one side close to each other along the fixed bar 11 on the same side for resetting, after resetting is finished, the step of fixing the second screw 16 and the second nut 17 on the first rotating bar 8 and the second rotating bar 10 can be repeated, after fixing is finished, people can use the screws to align the first L-shaped plate 7, the first rotating bar 8, the second rotating bar 10 and the left U-shaped plate 6, after aligning, the screws can be rotated, so that the screws fix the first L-shaped plate 7, the first rotating bar 8, the second rotating bar 10 and the left U-shaped plate 6, after the fixing, people can start to use the fireproof bridge, when the portable multifunctional movable fireproof bridge is not needed, the screws can be reversely rotated to be separated from the contact among the first L-shaped plate 7, the first rotating rod 8, the second rotating rod 10 and the left U-shaped plate 6, the screws do not fix the first L-shaped plate 7, the first rotating rod 8, the second rotating rod 10 and the left U-shaped plate 6, then the step of reversely rotating the second screws 16 and the second nuts 17 is repeated, the second nuts 17 do not fix the second screws 16, the second screws 16 do not fix the first rotating rod 8 and the second rotating rod 10, then the steps of moving the two U-shaped plates 6 to the side far away from each other can be repeated, the cables to be hidden are taken out, after the cables are taken out, the steps of moving the two U-shaped plates 6 to the side close to each other and resetting are repeated, after the U-shaped plate 6 is reset, the right U-shaped frame 1 can be turned upwards, the right U-shaped frame 1 drives the U-shaped plate 6 to be turned upwards and reset, the U-shaped plate 6 drives the second L-shaped plate 9 and the second rotating rod 10 to be turned upwards and reset, so that the right U-shaped plate 6 is contacted with the left U-shaped plate 6, after the U-shaped plate 6 is reset, the steps of fixing the second screw 16 and the second nut 17 on the second L-shaped plate 9 and the second rotating rod 10 are repeated, because the wheel 3 can be damaged after the wheel 3 is used for a long time, people need to replace the wheel 3, firstly, reversely rotate the first nut 5 to ensure that the first nut 5 is separated from the contact with the first screw 4, reversely rotate the first screw 4 to ensure that the first screw 4 is separated from the contact with the first fixing plate 2, then, take the first fixing plate 2 out of the U-shaped frame 1, and after the first fixing plate 2 is taken out, the wheel 3 on the first fixing plate 2 can be replaced, after waiting to change, alright with first fixed plate 2 card back on U type frame 1, aim at U type frame 1 and first fixed plate 2 with first screw 4, rotate first screw 4 again, make first screw 4 fix U type frame 1 and first fixed plate 2, aim at first screw 4 with first nut 5, aim at the back, again rotate first nut 5, make first nut 5 fix first screw 4, treat after fixed, alright continue to use this device, according to the above-mentioned operation, alright realize portable's multi-functional portable fire prevention crane span structure's use, drive this device through wheel 3 and remove, make this device remove more convenient.

Example 2

On embodiment 1's basis, refer to fig. 1 and 5, still including second fixed plate 13, second kelly 14 and return spring 15, both sides all are connected with second fixed plate 13 through the welded mode around the left part of two U templates 6, the joint has second kelly 14 between two second fixed plates 13 of homonymy, second kelly 14 is the plastics material, the cost is reduced, two second kellies 14 outsides all overlap there is return spring 15, and the both ends of the return spring 15 of homonymy are connected respectively on two second fixed plate 13 tops on upper portion and the second kelly 14 of homonymy through the welded mode.

When this device removes, because the road jolts, so wheel 3 can roll the stone occasionally, thereby lead to U type frame 1 of lower part to be extrudeed, U type frame 1 of lower part drives second kelly 14 and upwards removes, return spring 15 is compressed, when wheel 3 breaks away from the contact with the stone, under the effect that return spring 15 resets, second kelly 14 moves downwards thereupon and resets, so return spring 15 alright play the cushioning effect to U type frame 1, avoid two U type boards 6 to receive the collision and take place the sound, can not bring the trouble for people.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and not intended to limit the scope of the present invention, so that all equivalent changes made by the contents of the claims of the present invention should be included in the scope of the claims of the present invention.
