[0002] A scaffolding system is a common construction scaffolding system used to provide a safe working platform and support structure during construction. It consists of multiple horizontal crossbars and vertical vertical poles that are connected together using special connectors (usually clasps).

[0003] When constructing the existing disc-type scaffolding, it is necessary to insert the plug in the horizontal bar into the circular plug disk on the vertical bar, and then the worker uses a hammer to hit the pin from above to insert the pin into the plug and the circular plug disk, thereby achieving the effect of fixing the vertical bar to the horizontal bar. Then, the next level is built upwards. During the construction process, the two vertical bars are connected end to end and fixed with fastening bolts, and then the horizontal bar is fixed to the vertical bar through the connecting piece.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-9 , the present invention provides a technical solution:

[0031] Example 1:

[0032] A movable disc-type scaffolding includes an upright 1 and a cross bar 2. The upright 1 includes a connecting head 5 and a connecting seat 4. The lower end of the upright 1 is fixedly connected to the connecting seat 4, and the upper end of the upright 1 is fixedly connected to the connecting head 5. The upright 1 is provided with several groups and is connected end to end in sequence. The side wall of the upright 1 is fixedly connected to a disc 3, and both sides of the cross bar 2 are fixedly connected to buckle joints 10. Pin holes are provided on the buckle joints 10 and the disc 3 and are equipped with vertical pins 11. A locking mechanism 12 is installed inside the connecting head 5. The locking mechanism 12 is used to fix the connecting head 5 at the lower end of the adjacent upright 1. The fastening mechanism 7 is installed on the side wall of the upright 1. The fastening mechanism 7 moves downward to fix the pin 11, and moves upward to remove the fixed pin 11. The driving mechanism 6 is installed inside the upright 1. The driving mechanism 6 is used to drive the fastening mechanism 7 to move upward or downward and drive the locking mechanism 12 to operate.

[0033] The connecting head 5 at the upper end of the vertical pole 1 is connected to the connecting seat 4 at the lower end of the adjacent vertical pole 1, and then the driving mechanism 6 drives the locking mechanism 12 to operate, so that the vertical pole 1 and the adjacent vertical pole 1 can be fixed, thereby solving the problem of fixing with traditional bolts. At the same time, the operation of the driving mechanism 6 drives the fastening mechanism 7 to move downward, so that the fastening mechanism 7 will fix the pin 11, thereby preventing the pin 11 from loosening.

[0034] The side wall of the connector 5 is fixedly connected to a fixed sleeve 121, and a threaded rod 122 is rotatably connected inside the fixed sleeve 121. The threaded rod 122 is threadedly connected to a movable sleeve 124. The outer wall of the movable sleeve 124 is slidingly connected to the inner wall of the fixed sleeve 121. The end of the threaded rod 122 close to the axis of the connector 5 is fixedly connected to a third bevel gear 123. A limiting groove 125 is provided on the outer wall of the movable sleeve 124. A limiting block 126 is fixedly connected to the inner wall of the fixed sleeve 121. The limiting block 126 is located inside the limiting groove 125 and is slidingly connected to it.

[0035] The third bevel gear 123 rotates to drive the threaded rod 122 to rotate, and the threaded rod 122 rotates to drive the movable sleeve 124 to move, thereby providing power for the movement of the movable sleeve 124.

[0036] The side wall of the connecting seat 4 is equidistantly provided with positioning holes 13, which engage with the movable sleeve 124 in the adjacent upright 1; the movable sleeve 124 moves the inside of the positioning hole 13 to achieve the effect of engaging the connecting seat 4, thereby achieving the effect of fixing the connecting seat 4

[0037] The interior of the connecting seat 4 is set as a square groove, and the connecting head 5 is set as a square block. By setting the square block position and the interior of the square groove, the movable sleeve 124 in the connecting head 5 and the positioning hole 13 of the connecting seat 4 are located on the same axis, thereby avoiding the problem of manual alignment.

[0038] A limiting hole 74 is provided on the side wall of the upright pole 1, and a connecting block 72 is slidably connected to the inner wall of the limiting hole 74. The end of the connecting block 72 close to the axis of the upright pole 1 is fixedly connected to a threaded block 71, and the end of the connecting block 72 away from the threaded block 71 is fixedly connected to a pressure plate 73. The inner wall of the pressure plate 73 is slidably connected to the outer wall of the upright pole 1.

[0039] The threaded block 71 moves downward, driving the fixed block 81 downward. The fixed block 81 moves downward, driving the pressure plate 73 downward, so that the pressure plate 73 abuts against the latch 11, thereby preventing the latch 11 from loosening.

[0040] The vertical pole 1 is internally connected to a driving rod 61 for rotation. The driving rod 61 passes through the threaded block 71. A threaded groove 64 is provided on the side wall of the driving rod 61. The threaded groove 64 is threadedly connected to the threaded block 71. The side wall of the transmission rod 65 is fixedly connected to the first bevel gear 62 and the second bevel gear 63. The first bevel gear 62 is located above the second bevel gear 63, and the first bevel gear 62 is engaged with the third bevel gear 123.

[0041] The second bevel gear 63 rotates to drive the driving rod 61, and the driving rod 61 rotates to drive the first bevel gear 62, thereby providing power for the third bevel gear 123 to rotate. The driving rod 61 rotates while driving the thread groove 64 to rotate, thereby providing power for the thread block 71 to move.

[0042] The side wall of the upright pole 1 is rotatably connected to the transmission rod 65. The side of the transmission rod 65 close to the driving rod 61 is fixedly connected to the fourth bevel gear 66. The fourth bevel gear 66 is engaged with the second bevel gear 63. The end of the transmission rod 65 away from the fourth bevel gear 66 is fixedly connected to the handle 67.

[0043] The transmission rod 65 is driven to rotate by holding the handle 67 , and the rotation of the transmission rod 65 drives the fourth bevel gear 66 to rotate, and the rotation of the fourth bevel gear 66 drives the second bevel gear 63 to rotate, thereby providing power for the rotation of the second bevel gear 63 .

[0044] According to the above embodiment, embodiment 2,

[0045] The side wall of the upright pole 1 is fixedly connected to a fixed block 81 through a fastener 82, and the lower end of the fixed block 81 is fixedly connected to a jack 83. The telescopic end of the jack 83 is provided with a roller 84. Through the cooperation of the fixed block 81 and the fastener 82, the jack 83 with the roller 84 is conveniently fixed to the side wall below the upright pole 1.

[0046] The output end of the jack 83 is extended downward so that the roller 84 is in contact with the ground. At the same time, the lower end surface of the upright pole 1 is away from the ground. In cooperation with external traction equipment, it is moved so that the scaffolding is moved to the designated position, avoiding the problem of the scaffolding needing to be disassembled and then rebuilt at the designated position, thereby reducing the work intensity of the workers.

[0047] According to the above embodiment, embodiment three,

[0048] The left and right sides of the cross bar 2 are connected to levers 92 through the rotating shaft 91. The upper end of the lever 92 is fixedly connected to a connecting plate 93, and the lower end of the connecting plate 93 is fixedly connected to a spring 94. The end of the spring 94 away from the connecting plate 93 is fixedly connected to the side wall of the cross bar 2. The lower end of the lever 92 is fixedly connected to a top plate 95, and the upper end surface of the top plate 95 abuts against the lower end surface of the pin 11.

[0049] During the process of dismantling the scaffolding, when the pressure plate 73 moves to the top, the worker then uses a hammer to strike the connecting plate 93 from top to bottom, causing the connecting plate 93 to move downward, and the top plate 95 to move upward through the lever principle, thereby pushing the pin 11 out of the disc 3, avoiding the worker using a hammer to exert force from bottom to top, which would require multiple strikes to dismantle the pin 11 due to the direction and small space, thereby reducing the worker's work intensity.
