[0022] As Figures 1 to 2 shown, a fixing and installing device for a scaffold includes a vertical pole 1. A disc 2 is welded on the outer surface of the vertical pole 1. Cross bars 3 are horizontally distributed on the outer side of the disc 2. The disc 2 and the cross bars 3 are connected by bolt pins 4. It is characterized in that: a nut 6 is threadedly connected above the disc 2 on the vertical pole 1. The bottom of the nut 6 is coaxially and rotatably connected with a limit disc 7. The limit disc 7 is slidably connected to the outer side of the vertical pole 1. Openings of the same size are respectively formed through the nut 6 and the limit disc 7 in the middle.
[0023] A limit groove 8 is formed on one side of the limit disc 7 close to the disc 2. The limit groove 8 is adapted to the top end of the bolt pin 4.
[0024] An external thread groove is formed on the outer side of the vertical pole 1. An internal thread groove adapted to the external thread groove is formed on the inner wall of the nut 6. The external thread groove and the internal thread groove are meshed with each other.
[0025] A vertical strip-shaped groove is formed on the external thread groove. A sliding block adapted to the strip-shaped groove is integrally formed on the inner wall of the limit disc 7. One end of the sliding block is arranged in the strip-shaped groove and is slidably matched with it.
[0026] Bolt pin holes 5 with different shapes are respectively formed through the disc 2. Each bolt pin hole 5 is matched with a corresponding bolt pin 4 for fixing the cross bar 3.
[0027] A U-shaped connecting piece is welded at one end of the cross bar 3 close to the disc 2, and the opening of the U-shaped connecting piece faces the disc 2.
[0028] During specific operation, the opening of the U-shaped connecting piece is made to face the disc 2 in advance, and the U-shaped connecting piece is clamped on the surface of the disc 2. Through holes adapted to the bolt pin holes 5 are respectively formed on the U-shaped connecting pieces. A bolt pin 4 adapted to the bolt pin holes 5 and the through holes is selected and inserted into the bolt pin holes 5 and the through holes to fix the cross bar 3 and the vertical pole 1. During the repeated use of the bolt pin 4, certain wear is caused. When an operator stands on the scaffold for construction, the scaffold is not stable enough and shakes. In order to improve the repeated utilization rate of the bolt pin 4 and ensure the stability of the scaffold, the nut 6 on the vertical pole 1 can be rotated. The rotation of the nut 6 drives the limit disc 7 to move towards the top end of the bolt pin 4 until the top end of the bolt pin 4 is clamped inside the limit groove 8, so that three surfaces on the inner wall of the limit disc 7 tightly abut against four surfaces at the upper end of the bolt pin 4, making the bolt pin 4 tightly inserted between the disc 2 and the cross bar 3, preventing the scaffold from shaking due to the wear of the bolt pin 4.
[0029] AsFigures 2 to 4 As shown, a limiting column 9 is welded to one side of the U-shaped connecting piece close to the limiting disc 7, a limiting rod 10 is welded to one side of the limiting disc 7 close to the limiting column 9, and a groove 11 adapted to the limiting rod 10 is formed inside the limiting column 9.
[0030] The number of the limiting rods 10 corresponds to the number of the pin holes 5, and the multiple limiting rods 10 are annularly distributed.
[0031] During specific operation, in order to prevent the pin 4 from breaking after wear, a limiting column 9 is arranged above the U-shaped connecting piece. While the nut 6 rotates to drive the limiting disc 7 to move towards the direction of the disc 2, the limiting rod 10 directly above the limiting column 9 is driven to move towards the limiting column 9, so that one end of the limiting rod 10 is inserted into the groove 11 adapted to it, which can prevent the vertical rod 1 and the cross rod 3 from being separated due to the wear and breakage of the pin 4, resulting in the collapse of the scaffold. At the same time, as the wear degree of the pin 4 increases, the moving distance of the limiting disc 7 towards the disc 2 slowly increases until the limiting rod 10 is completely inserted into the limiting column 9. At this time, the limiting disc 7 reaches the maximum moving path, and the wear of the pin 4 reaches the maximum, so that the pin 4 can be replaced in time.
