[0013] like Figures 1-4 As shown, a wire-pulling device for measuring the camber of a main beam includes a main beam 1. A camber measuring device is installed on the top of the main beam 1. The camber measuring device includes a base, which comprises a base plate 3 and two side plates 4. One end of the base plate 3 has a hook structure, and one end of the hook is hung on one end of the top plate of the main beam 1. A rotating core 6 is rotatably connected between the two side plates 4. A steel wire 7 is wound around the rotating core 6. A horizontally arranged rotating shaft 8 is threaded through the rotating core 6 and fixedly connected to the rotating core 6. Both ends of the rotating shaft 8 pass through the two side plates 4 and are rotatably connected to them. The other end of the main beam 1 is connected to... Hook 5 is connected to the end of wire 7 by a spring scale 9. Specifically, one end of the hook of the base plate 3 of this device is hung on the end of the main beam 1 to fix the rotating core 6. Then the wire 7 is pulled out and hung on one end of the spring scale 9. The spring scale 9 can directly see the magnitude of the tension. When the tension is 150N, the wire 7 no longer moves. The end of hook 5 connected to the spring scale 9 is set to be inclined upward so that the wire 7 is horizontal when it is straightened. Based on this, the distance between the highest point of the middle position of the main beam 1 and the wire 7 is measured.
[0014] A handle 11 is connected to one end of the rotating shaft 8. Specifically, the handle 11 has an L-shaped structure and is integrally connected to the rotating shaft 8. When the handle 11 is held by hand and the rotating shaft 8 is rotated, the rotating core 6, which is fixedly connected to the rotating shaft 8, will rotate accordingly, thereby realizing the winding and unwinding of the steel wire.
[0015] The two ends of the rotating core 6 are fixedly connected to baffles 14. Multiple fixing holes 15 are distributed around the circumference of the baffles 14. A fixing hole 2 16 is also opened on one of the side plates 4. The fixing pin 12 passes through the fixing hole 15 and the fixing hole 2 16. Specifically, after the steel wire 7 is fixed, the fixing pin 12 is inserted into the fixing hole 15 and the fixing hole 2 16, and the rotating core 6 is fixed.
[0016] One end of the circular part of the fixing pin 12 is connected to an iron chain 13, and the other end of the iron chain 13 is connected to one of the side plates 4. Specifically, both the iron chain 13 and the fixing pin are made of iron and are fixed by welding. The iron chain 13 can prevent the fixing pin 12 from being lost.
