Bolts are screwed into the side wall of the fixed ring 9, and the support plates 21 and the fixed block 28 are fixed by the bolts to increase the stability of the equipment. A wire cylinder 29 is vertically arranged at the central position of the fixed block 28, a cushion block 291 is arranged at the bottom of the wire cylinder 29, and the cushion block 291 is a suction cup or an electromagnet, which is convenient for adsorbing on the steel truss below, and the fixed ring 9 is suspended directly above the steel truss. An activity frame 30 is slidably arranged on the support plate 21, a clamping plate 31 and a reinforcing rod 32 are rotatably arranged at the bottom end of the activity frame 30, the clamping plate 31 and the reinforcing rod 32 form a scissor structure, and clamping parts 40 are arranged at one ends of the clamping plate 31 and the reinforcing rod 32. A transmission rod 37 is slidably arranged inside the activity frame 30, a ball head 371 matched with the support plate 21 is arranged at the top end of the transmission rod 37, an inclined groove is arranged at the bottom of the support plate 21, and the ball head 371 can slide along the inclined groove. A pressing plate 35 is slidably arranged at the bottom end of the transmission rod 37, and the bottom of the pressing plate 35 presses the clamping plate 31 and the reinforcing rod 32 downward. When the clamping plate 31 cannot move, the pressing plate 35 slides horizontally and continues to press the reinforcing rod 32 to rotate, which is convenient for fixedly clamping the steel members on steel trusses of different sizes. The bottom end of the traction rope 27 passes through the wire cylinder 29 and is connected with the activity frame 30; A driving mechanism, which is connected with the rotating rod 24. When the rotating rod 24 rotates self, the rotating block 25 cannot pull the steel wire rope 8. At this time, the fixed ring 9 cannot move up and down. The rotating rod 24 drives the rotating cylinder 26 to rotate. The rotating cylinder 26 rotates and winds a plurality of traction ropes 27 thereon. The traction ropes 27 pull the plurality of activity frames 30 to approach each other. The ball head 371 on the transmission rod 37 slides along the inclined groove, so that the transmission rod 37 drives the pressing plate 35 to descend. The pressing plate 35 presses the clamping plate 31 and the reinforcing rod 32 to rotate downward, so that the two clamping parts 40 approach each other, and the steel members on the steel truss can be clamped, realizing the fixed clamping of the whole steel truss; When the rotating cylinder 26 cannot rotate, the rotating rod 24 drives the turntable 22 to rotate. The turntable 22 drives the two rotating rods 24 to rotate along the rotating shaft 221. The steel wire rope 8 is wound outside the two rotating rods 24, and can pull the movable plate 12, the fixed frame 11 and the fixed ring 9 to rise.

[0025] As Figure 3-8As shown, as a preferred embodiment of the present invention, the driving mechanism includes a power member disposed on the turntable 22, a transmission gear 39 disposed outside the rotating rod 24, and a gear 38 meshing with the transmission gear 39.

A limiting plate 123 is disposed outside the movable plate 12, and one end of the limiting plate 123 contacts the turntable 22. The limiting plate 123 limits the turntable 22 by friction, so that the turntable 22 cannot rotate freely.

[0026] As Figure 1-8 shown, as a preferred embodiment of the present invention, a limiting groove 111 is formed on the outer side wall of the fixing frame 11. The limiting groove 111 is Figure 5 shown as an inclined groove. A clamping plate 36 is slidably disposed on the side wall of the movable plate 12. One end of the clamping plate 36 penetrates into the limiting groove 111. A return spring 361 is disposed between the clamping plate 36 and the movable plate 12; when the rotating cylinder 26 is located on the left side of the square groove 121 (i.e., Figure 8 the position shown), the gear disk 261 meshes with the transmission gear 39. The motor 23 drives the rotating rod 24 and the transmission gear 39 to rotate. The transmission gear 39 drives the gear 38 and the rotating shaft 221 to rotate. Due to the friction of the limiting plate 123, the turntable 22 cannot rotate. The transmission gear 39 drives the rotating cylinder 26 to rotate through the gear disk 261. The rotating cylinder 26 fixes the steel truss through the cooperation with the traction rope 27. After the steel truss is fixed, the traction rope 27 continues to be wound up, and the movable plate 12 slides down along the fixing frame 11, and the clamping plate 36 descends along the limiting groove 111. After the card block 34 penetrates into the card slots 331, the rotating cylinder 26 and the gear disk 261 cannot rotate continuously, and the rotating rod 24 and the transmission gear 39 rotate along the inner wall of the gear disk 261, that is, the turntable 22 drives the two rotating rods 24 to rotate along the rotating shaft 221 (at this time, the rotating rod 24 is still rotating self). The steel wire rope 8 is wound around the two rotating rods 24, and can pull the fixing ring 9 and the steel truss upward to rise, realizing the hoisting of the steel truss.

The telescopic cylinder 19 drives the connecting plate 20 to move up and down, facilitating the adjustment of the inclination angle of the support rod 6.

[0028] As Figure 1-2 shown, as a preferred embodiment of the present invention, an adjusting plate 1 is provided at the bottom of the base 2. A lead screw 17 is provided inside the adjusting plate 1. A threaded hole matching the lead screw 17 is provided at the bottom of the base 2. A driving motor 18 is provided on the side wall of the adjusting plate 1, and the rotating end of the driving motor 18 is connected to the lead screw 17. The driving motor 18 drives the lead screw 17 to rotate, and the lead screw 17 drives the base 2 to move left and right.

[0029] As Figure 1-2 shown, as a preferred embodiment of the present invention, a bottom plate 13 is provided below the adjusting plate 1. A plurality of rollers 14 and screw rods 15 are provided on the bottom plate 13, and a support leg 16 is provided at the bottom end of the screw rod 15.

[0030] In the above embodiments of the present invention, a steel truss splicing and hoisting construction device is provided. The entire hoisting device is moved to the construction area through the bottom plate 13 and the base 2. The fixing ring 9 is moved directly above the steel truss, so that the cushion block 291 is in contact with the top of the steel truss. In the initial position, the movable plate 12 is located above the inside of the fixing frame 11, and the rotating cylinder 26 is located on the left side of the square groove 121. The motor 23 drives the rotating rod 24 and the transmission gear 39 to rotate. The rotating cylinder 26 fixes the steel truss through the cooperation with the traction rope 27. When the steel truss is fixed, the traction rope 27 continues to be wound up, and the clamping block 34 penetrates into the inside of the card slot 331, making the rotating cylinder 26 unable to rotate. The turntable 22 drives the two rotating rods 24 to rotate along the rotating shaft 221, and the steel wire rope 8 is wound around the two rotating rods 24, pulling the fixing ring 9 and the steel truss upward, realizing the hoisting of the steel truss; after the steel truss is installed, the rotating cylinder 26 is moved to the right side of the square groove 121, so that the clamping block 34 is separated from the card slot 331, and the gear disk 261 is disengaged from the transmission gear 39, and the rotating cylinder 26 can rotate. The plurality of movable frames 30 move away from each other to separate the construction device from the steel truss below.
