Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] like Figure 1As shown, a protective working platform with integrated stone support includes a base and a guardrail 1 arranged on the base. The base and the guardrail 1 form an integral structure, which is convenient for hoisting the working platform. The structure is stable, firm and durable, easy to lift, install and disassemble, and saves materials. It can be used repeatedly after one investment. There is no need to install a protective fence around the pier top, which reduces the danger. The base is composed of an upper frame 2 and a lower frame 3. A positioning mechanism for positioning the platform is provided between the upper frame 2 and the lower frame 3. The positioning mechanism is used to position the working platform to prevent the working platform from moving on the pier top, and the stability is good.

[0023] like Figure 1 As shown, the positioning mechanism includes a clamping claw 4 symmetrically arranged in the base and sliding in the base, and a driving mechanism is provided in the base to drive the clamping claws 4 on both sides to move synchronously in the same direction or in opposite directions. When the working platform is hoisted to the top of the pier, the clamping claws 4 on both sides are driven by the driving mechanism to move in the same direction, and the clamping claws 4 clamp the side of the pier top, thereby fixing the position of the working platform.

[0024] like Figure 2 As shown, a sleeve 6 is provided in the base, and the clamping jaw 4 passes through the sleeve 6 and slides in the sleeve 6 , and the movement of the clamping jaw 4 is guided by the sleeve 6 .

[0025] like Figure 2 As shown, a rotating plate 7 is provided at the lower end of the clamp 4, and a first driving rod 8 inclined inward from bottom to top is provided at the upper end of the rotating plate 7. When the clamp 4 moves inward, the first driving rod 8 contacts the side surface of the pier top, and the rotating plate 7 rotates inward, close to the inclined position of the upper end of the side surface of the pier top, so as to better fix the working platform.

[0026] like Figure 2 As shown, a clamping groove 9 cooperating with the first driving rod 8 is provided on the inner side of the clamping jaw 4 .

[0027] like Figure 3 As shown, two clamping jaws 4 are provided on each side, and the clamping jaws 4 on the same side are connected as a whole through a connecting rod 5.

[0028] like Figure 3 As shown, the driving mechanism includes a driving disk 10 arranged in the base and rotating in the base, and the driving disk 10 is connected to the corresponding connecting rod 5 through the second driving rod 11 respectively, and the inner end of the second driving rod 11 is rotatably connected to the driving disk 10 at an eccentric position, and the positions where the inner ends of the two second driving rods 11 are rotatably connected to the driving disk 10 are symmetrical on the driving disk 10, and the outer end of the second driving rod 11 is rotatably connected to the connecting rod 5. When the driving disk is rotated, under the action of the second driving rod 11, the clamps on both sides move synchronously to clamp or release the pier top.

[0029] like Figure 3As shown, a handle 12 is provided on the rotating shaft of the driving disk 10, and a locking screw 13 is provided on the handle 12. The driving disk is rotated by the handle 12, and after the driving disk is rotated to a certain position, it is locked by the locking screw 13.
