[0025] This embodiment is a lifting device for fire protection installation projects.

[0026] As Figures 1-5 shown, it includes a base 1 and a top plate 3. A scissor lift structure 2 is installed between the lower outer surface of the top plate 3 and the upper outer surface of the base 1. Locking universal wheels 4 are fixedly installed at the four corners of the lower outer surface of the base 1. Storage grooves 7 are opened on the left and right sides of the upper outer surface of the top plate 3. Damping rotating shafts 8 are installed at both ends of the storage groove 7. Support arms 5 are arranged at the four corners of the upper outer surface of the top plate 3. The number of the support arms 5 is four groups. A rectangular fence 6 is installed between the four groups of support arms 5. A clamping component 9 is installed on one outer surface of the support arm 5. The clamping component 9 includes an installation groove 10, a threaded hole 11, a screw 12, a compression spring 13, a movable block 14 and an upper inclined wedge block 15. Clamping grooves 16 are opened on the left and right sides of the outer surfaces at both ends of the rectangular fence 6. The lower end of the support arm 5 is rotatably connected to the top plate 3 through a damping rotating shaft 8. A threaded groove is opened in the middle of the outer surface of one end of the movable block 14 away from the upper inclined wedge block 15.

[0027] The installation groove 10 is opened on one outer surface of the support arm 5. The threaded hole 11 is opened on the other outer surface of the support arm 5. The threaded hole 11 communicates with the installation groove 10; both the compression spring 13 and the movable block 14 are located in the installation groove 10. The screw 12 penetrates through the threaded hole 11, and the outer wall of the screw 12 is in threaded connection with the threaded hole 11, and the outer wall of the screw 12 is in threaded connection with the threaded groove; one outer surface of one end of the upper inclined wedge block 15 is fixedly connected to one outer surface of one end of the movable block 14. The compression spring 13 is fixedly installed between the outer surface of the other end of the movable block 14 and the outer surface of one end of the installation groove 10; the outer walls of the movable block 14 and the upper inclined wedge block 15 are in sliding connection with the installation groove 10, and one outer surface of one end of the movable block 14 is elastically connected to one end of the installation groove 10 through the compression spring 13; the outer wall of the upper inclined wedge block 15 is in clamping connection with the clamping groove 16.

[0028] It should be noted that the present utility model is a lifting device for a fire protection installation project. The scissor lift structure 2 described in the text belongs to the prior art. The scissor lift structure 2 can drive the top plate 3 to rise, which can be effectively known to those skilled in the art, and will not be elaborated here. The provided support arm rod 5 can be stored through the provided storage groove 7. When the rectangular fence 6 needs to be assembled, rotate the support arm rod 5, and the support arm rod 5 rotates and stands up around one end of the damping rotating shaft 8. Then, install the rectangular fence 6 between the four groups of support arm rod 5. The rectangular fence 6 presses the upper inclined wedge block 15 in the clamping component 9 downward from above, driving the upper inclined wedge block 15 and the movable block 14 to slide along the installation groove 10, so that one end of the upper inclined wedge block 15 enters the installation groove 10, and the movable block 14 presses the compression spring 13 in the installation groove 10. When the clamping groove 16 in the rectangular fence 6 reaches the position of the upper inclined wedge block 15, due to the reset action of the compression spring 13, the upper inclined wedge block 15 and the clamping groove 16 are clamped to complete the installation of the rectangular fence 6. When disassembling, squeeze the upper inclined wedge block 15 clamped in the clamping groove 16 to separate the upper inclined wedge block 15 from the clamping groove 16. Then, rotate the screw rod 12, and the screw rod 12 is connected to the thread groove at one end of the movable block 14 away from the upper inclined wedge block 15 to fix the movable block 14, avoiding the upper inclined wedge block 15 resetting due to the reaction of the compression spring 13 when operating other clamping components 9. Through the limit of the screw rod 12, during disassembly, one person can complete the disassembly work.
