[0037] A foldable climbing frame for building construction includes a work platform 1, a slide groove 2 on the top of the work platform 1, and a movable seat 3 slidably connected in the slide groove 2.

[0038] The lifting assembly includes an electric push rod 4 fixedly connected to the top of the movable seat 3. A movable sleeve 5 is fixedly connected to the top of the electric push rod 4. A rotating shaft 6 is rotatably connected inside the movable sleeve 5. Two rotating rods 7 are rotatably connected to both ends of the rotating shaft 6. Support blocks 8 are hinged to the left ends of two adjacent rotating rods 7 through two pins. Moving blocks 9 are hinged to the right ends of two adjacent rotating rods 7 through two pins. The top of the two upper support blocks 8 is fixedly connected to the same support platform 10.

[0039] The alarm assembly includes four buffer springs 11 fixedly connected to the bottom of the workbench 1. Each of the four buffer springs 11 has a pressing block 12 fixedly connected inside it. The bottom of each of the four buffer springs 11 is fixedly connected to the same base 13. Each of the four buffer springs 11 has a pressing switch 14 fixedly connected inside it.

[0040] Four push-button switches 14 are fixedly connected to the top of the base 13. Four warning lights 15 are fixedly connected to the top of the workbench 1. The warning lights 15 are electrically connected to the push-button switches 14. Two guide grooves 16 are opened on the top of the workbench 1. Two support blocks 8 located below are fixedly connected to the top of the workbench 1.

[0041] By incorporating a support platform 10, a buffer spring 11, a pressing block 12, a pressing switch 14, and a warning light 15, the device can automatically alarm in case of overload, preventing the device from becoming dangerous due to continued use under overload conditions and ensuring the device's effectiveness.

[0042] Second embodiment:

[0043] Specifically, such as Figure 1-3As shown, two guide posts 17 are fixedly connected to the top of the base 13. The guide posts 17 are slidably connected in the corresponding guide grooves 16. By setting the guide grooves 16, and the cooperation between the guide grooves 16 and the guide posts 17, the worktable 1 can be prevented from shifting or misaligning when it moves, thus ensuring the stable use of the worktable 1. Two limit grooves 18 are opened on the top of the worktable 1.

[0044] By setting a limiting groove 18, and the cooperation between the limiting groove 18 and the moving block 9, the situation of the moving block 9 being offset and stuck during movement can be avoided, thus ensuring the stable movement of the moving block 9.

[0045] The two lower movable blocks 9 are slidably connected in the corresponding limiting grooves 18. The bottom of the support platform 10 has two fixed grooves 19. The two upper movable blocks 9 are slidably connected in the corresponding fixed grooves 19. The top of the support platform 10 is provided with a protective frame 20. The bottom of the base 13 is provided with four self-locking casters. The top of the base 13 is provided with a fixed stool. The four pressing blocks 12 are all fixedly connected to the bottom of the workbench 1.

[0046] By incorporating an electric push rod 4, a movable sleeve 5, a rotating shaft 6, a rotating rod 7, a support block 8, and a movable block 9, the device can automatically raise the support platform 10 and the protective frame 20 to a suitable position, thereby improving the automation level of the device and facilitating its folding and use.

[0047] Working principle and usage: First, the device can be moved to a suitable position using the self-locking casters. Then, the operator can carry tools and enter the support platform 10 through the fixed stool. Under the action of gravity, the worktable 1 moves the four pressing blocks 12 downwards and simultaneously compresses the four buffer springs 11. When the load is too high, the pressing blocks 12 can press the button switch 14, causing the warning light 15 to flash and stop use. If the indicator light does not light up, the electric push rod 4 can be activated. The electric push rod 4 pushes the moving sleeve 5 and the rotating shaft 6 upwards, thereby causing the four corresponding rotating rods 7 to rotate in opposite directions. At the same time, the moving seat 3 drives the electric push rod 4 to slide to the left in the slide groove 2. The rotating rods 7 can drive the two moving blocks 9 located above to slide to the left in the fixed groove 19, while the two moving blocks 9 located below can slide to the left in the limit groove 18, thereby raising the support platform 10 and the protective frame 20 to a suitable position.
