[0024] The construction platform includes a standing board 8, the four corners of the upper surface of the standing board 8 are fixedly connected to vertical poles 9, the upper ends of the four vertical poles 9 are fixedly connected to the same rectangular guardrail 10, and the outer sides of the four vertical poles 9 are provided with a rectangular ring seat 7 for translation at the upper ends of the two door-shaped side frames 2, and one side of the rectangular ring seat 7 is provided with a lifting component 4 for driving the standing board 8 to move up and down.
[0025] Reference Figure 2As shown, the bolt connector 3 includes an insert block 3a fixedly connected to the two ends of the bottom of the gate-shaped side frame 2, a slot 3b is provided on the upper surface of the base frame 1, and the end of the base frame 1 is provided with a bolt hole 3c connected to the slot 3b, and a bolt 3d is threadedly connected to the bolt hole 3c. The insert block 3a is provided with a fixing hole 3e for inserting with the bolt 3d. After the insert block 3a is inserted into the slot 3b, the bolt 3d is rotated in the bolt hole 3c until the end of the bolt 3d is inserted into the fixing hole 3e, thereby completing the fixation of the gate-shaped side frame 2.
[0026] Furthermore, T-shaped strips 14 are fixedly connected to both sides of the stabilizing frame 6, and T-shaped slots 15 for connecting with the T-shaped strips 14 are provided at the opposite ends of the two door-shaped side frames 2. After the two door-shaped side frames 2 are installed, the stabilizing frame 6 is vertically inserted between the two door-shaped side frames 2, and the T-shaped strips 14 are slid downward in the T-shaped slots 15 to complete the installation of the stabilizing frame 6. The stabilizing frame 6 can reinforce the space between the two door-shaped side frames 2, making the door-shaped side frames 2 more stable.
[0027] Reference Figure 3 As shown, the four corners of the bottom surface of the rectangular ring seat 7 are rotatably connected to the rollers 13 that abut against the upper end surface of the door-shaped side frame 2. Both sides of the bottom surface of the rectangular ring seat 7 are fixedly connected to the limiting side plates 12, and the two limiting side plates 12 are respectively located on the outside of the two door-shaped side frames 2. One of the limiting side plates 12 is provided with an extrusion fixing member 5 for fixing the position of the rectangular ring seat 7. The extrusion fixing member 5 includes an extrusion plate 5c located on the inner side of the limiting side plate 12. The middle part of the extrusion plate 5c is rotatably connected to a bolt 5b.

The stabilizing rod 16 can improve the overall structural strength of the portal side frame 2, and the limit blocks 17 can limit the movement of the rectangular ring seat 7 to prevent the rectangular ring seat 7 from moving out of the portal side frame 2. The universal wheel 18 can enable the device to move flexibly, and at the same time, the locking structure can lock the universal wheel 18 when it is not moving.
[0030] Working principle:
[0031] Place the base frame 1 stably, then place the two door-shaped side frames 2 vertically on both sides of the upper surface of the base frame 1, and fix them with bolt connectors 3, then install the two stabilizing frames 6 at both ends between the two door-shaped side frames 2, and then place the rectangular ring seat 7 horizontally on the upper surfaces of the two door-shaped side frames 2, so that it can move horizontally on the upper end surfaces of the two door-shaped side frames 2. At this time, the construction platform is located between the two door-shaped side frames 2, and the staff can enter it and drive the standing board 8 to move up and down through the lifting assembly 4, so that the staff can perform lifting operations.
