[0032] Working principle:

[0033] When the portable mobile fire-fighting and rescue lifting platform is used, the lifting platform is moved to a suitable position by the guide wheel 2, the hydraulic cylinder 3 drives the support plate 4 to descend, so that the support plate 4 contacts the ground, and the guide wheel 2 is separated from the ground, so that the platform is more stable when working. According to the rescue needs, the appropriate tool is selected. When a water cannon is needed, the water cannon is placed on the surface of the standing platform 5, and the positioning bolts are screwed into the threaded holes on the surface of the limit frame 6 so that the positioning bolts are tightly attached to the surface of the supporting feet of the water cannon to fix the position of the water cannon. The lifting seat 1 drives the standing platform 5 to rise to a suitable height, and the fire is put out by the water cannon.

[0034] When it is necessary to use a water gun or a lighting lamp, the rescuer stands on the surface of the standing platform 5, adjusts the adjustment tube 9 to a suitable height according to the rescuer's use requirements, and then places the water gun or the lighting lamp on the surface of the support frame 13, and drives the adjustment shaft 14 to rotate through the turntable 19, thereby driving the two guide blocks 15 and the fixing plate 16 to move toward each other, so that the fixing blocks are tightly attached to the two sides of the water gun or the lighting lamp, and the position of the water gun or the lighting lamp is fixed. The lifting seat 1 drives the standing platform 5 to rise to a suitable height, and the rescuer quickly adjusts the angle of the support frame 13 through the adjustment rod 20 and the universal ball head 12. During the rescue process, the angle of the water gun and the lighting lamp can be quickly adjusted, which is more flexible to use;

[0035] When it is necessary to use cutting equipment, the adjusting tube 9 is removed from the fixing tube 8, and the rescuer stands on the surface of the standing platform 5. The lifting seat 1 drives the standing platform 5 to rise to a suitable height, and the object is demolished by the cutting equipment. At the same time, the protective plate 7 plays a protective role to ensure the safety of the rescuer during the demolition process.
