[0028] The movement of the movable plate 7 drives the two chains to move, and drives the support plate 9 to move between the fixed plate 1 5 and the fixed plate 2 6. The support plate 9 is laid flat by pressing one end of the support plate 9 away from the blocking device 10. Then the support plate 9 under the gear roller 4 is rotated to be flat, so that the support plate 9 can be laid flatly up and down by the employees.

[0029] like Figure 7 and Figure 8 As shown, two sides of the support plate 9 are fixedly connected with four insertion rods 91, and the opposite side of each group of bearing members is provided with a plug hole 87.

[0030] When the support plate 9 is laid flat, the blocking rod 88 can be used to fix the insertion rod 91 to prevent the support plate 9 from rotating and prevent people from standing unsteadily. At the same time, it is convenient for the support plate 9 located below the gear roller 4 to rotate and lay flat, making it convenient for workers to raise and lower the support plate 9.

[0031] like Figure 6 As shown, one end of the bottom surface of the horizontal plate 81 is fixedly connected to an L-shaped plate 83, and the other end of the bottom surface of the horizontal plate 81 is fixedly connected to a convex plate 84.

[0032] The L-shaped plate 83 and the convex plate 84 are rotatably connected to facilitate the rotatable connection of adjacent transverse plates 81 , and at the same time, the side surfaces of two adjacent transverse plates 81 abut against each other to prevent the transverse plates 81 from being concave, making the support plate 9 unstable.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, a group of connecting plates 51 are fixedly connected to the opposite surfaces of the fixed plate 1 5 and the fixed plate 2 6, a threaded rod 52 is rotatably connected between one group of connecting plates 51, one end of the threaded rod 52 is fixedly connected to a rotating rod 1 54, and a guide rod 1 62 is fixedly connected between the other group of connecting plates 51, and sliders 71 are fixedly connected to both ends of the movable plate 7, one of the sliders 71 is threadedly sleeved with the threaded rod 52, and the other slider 71 is slidably sleeved with the guide rod 1 62.

[0035] like Figure 3 As shown, the clamp 11 includes a clamp body 111 that conflicts with the bottom surface of the inner wall of the angle steel 1, a nut 112 is fixedly connected to one side of the clamp body 111, a screw rod 113 is connected to the internal thread of the nut 112, a clamp plate 114 for fixing the side wall of the angle steel 1 is slidably sleeved on the outer wall of the screw rod 113, a conflicting bolt 115 is threadedly connected to the side wall of the clamp plate 114, one end of the conflicting bolt 115 conflicts with the side wall of the angle steel 1, a hanging hole 116 is provided at the bottom of the clamp body 111, a hook 21 is fixedly connected to the top and bottom surfaces of the support column 2, the hook 21 on the top surface of the support column 2 is clamped with the hanging hole 116, a plurality of hanging columns 32 are fixedly connected to both sides of the bearing plate 3, and the hanging columns 32 are clamped with the hook 21 on the bottom surface of the support column 2;

[0036] By screwing the screw rod 113, the top end of the screw rod 113 squeezes the angle steel 1 so that the lower inner wall of the angle steel 1 is tightly attached to the upper inner wall of the clamp body 111. By abutting the bolt 115, the side inner wall of the angle steel 1 squeezes the side wall of the clamp body 111, thereby fixing the clamp 11 and the angle steel 1.

[0037] like Figure 5 As shown, the blocking device 10 includes a fixing plate 3 101 fixed on the top surface of the support plate 9, a guide rod 2 102 is fixedly connected to one side of the fixing plate 3 101, a fan-shaped block 104 is slidably sleeved on the outer wall of the guide rod 2 102, a spring 2 103 is fixedly connected to the opposite surface of the fixing plate 3 101 and the fan-shaped block 104, and the guide rod 2 102 is placed inside the spring 2 103;

[0038] When the fan-shaped block 104 slides inward along the guide rod 102, the support plate 9 can rotate counterclockwise, which is convenient for laying flat and using as a ladder. When the bottom surface of the fan-shaped block 104 is fixed to the top surface of the horizontal plate 81, the support plate 9 can be prevented from rotating counterclockwise, and the support plate 9 can be fixed, so that the support plate 9 can be stabilized when people step on it.

[0039] like Figure 1 and Figure 6 As shown, one side of the transverse plate 81 is rotatably connected to a third insertion rod 86 , and the top surface of the bearing plate 3 is provided with a plurality of third through holes 31 adapted to the third insertion rod 86 .

[0041] Working principle of the present invention: when in use, firstly, the hook 21 at the bottom of the support column 2 is sleeved on the hanging column 32 of the bearing plate 3, and the hook 21 at the top of the support column 2 is extended into the hanging hole 116 of the clamp 11, and then the connecting plates 51 at both ends of the fixing plate 1 5 and the connecting plates 51 at both ends of the fixing plate 2 6 are inserted into the through holes 1 22 of the two adjacent support columns 2, so that the two fixing plates 2 6 and the fixing plate 1 5 are fixed between the two adjacent support columns 2, and then the slide grooves 41 at both ends of the gear roller 4 are inserted into the through holes 2 23 of the two parallel support columns 2, so that the gear roller 4 is fixed, and then the teeth 82 on the bottom surface of the support member 8 are inserted into the through holes 23 of the two parallel support columns 2, so that the gear roller 4 is fixed. Insert it in the tooth groove of the gear roller 4, then rotate the rotating rod 54 to drive the threaded rod 52 to rotate, so that the slider 71 moves along the threaded rod 52 to make the movable plate 7 move to one end of the fixed plate 1 5 and the fixed plate 2 6, and then press the support plate 9 away from one end of the blocking device 10, so that the bottom end of the fan block 104 moves to the top surface of the cross plate 81, and then the support plate 9 is laid flat between the two angle steels 1, and the support plate 9 under the gear roller 4 is flipped over so that the support plate 9 is laid flat to facilitate the staff to go up and down, and finally the staff moves to the support plate 9 between the fixed plate 1 5 and the fixed plate 2 6 to work.
