[0022] refer to Figure 3 The limiting device 8 includes two limiting blocks 801, the bottom of the limiting blocks 801 is fixedly connected to a stabilizing shell 802, and the left and right sides of the adjusting shell 5 are fixedly connected to stabilizing rods 803 used in conjunction with the stabilizing shell 802. The opposite sides of the two stabilizing rods 803 penetrate the stabilizing shell 802 and extend to the outside of the inner cavity of the stabilizing shell 802. The opposite sides of the two stabilizing rods 803 are fixedly connected to springs 804, and the opposite sides of the two springs 804 are fixedly connected to the surface of the stabilizing shell 802.

[0023] With the above solution, by providing the limiting device 8 , when the adjusting column 6 moves to a suitable height, the limiting device 8 has a limiting effect on the position of the adjusting column 6 .

[0024] refer to Figure 3 The rear side of the limit block 801 is fixedly connected to an extrusion block 9, and the left and right sides of the front side of the control panel 7 are movably connected to two extrusion rotating shells 10 used in conjunction with the extrusion block 9 through a rotating shaft, and the surface of the extrusion block 9 is movably connected to the inner cavity of the extrusion rotating shell 10.

[0025] The above scheme is adopted: by setting the extrusion block 9 and the extrusion rotating shell 10, when the control board 7 moves, it will drive the extrusion rotating shell 10 to rotate along the surface of the extrusion block 9. The extrusion force generated by the extrusion rotating shell 10 on the extrusion block 9 can drive the extrusion block 9 to move, and when the extrusion block 9 moves, it can drive the limit block 801 to move.

[0029] The above solution is adopted: by setting the moving shell 12 and the moving block 13, when the control board 7 moves, the moving shell 12 will be driven to move along the surface of the moving block 13. The coordinated use of the moving shell 12 and the moving block 13 has a limiting effect on the moving position of the control board 7.

[0030] refer to Figure 4 The left and right sides of the adjusting column 6 are both provided with limiting grooves 14 for use with the limiting block 801 , and the surface of the limiting block 801 contacts the inner cavity of the limiting groove 14 .

The coordinated use of the limit block 801 and the limit groove 14 has a limiting effect on the position of the adjustment column 6.

[0032] refer to Figure 2 A slider 15 is fixedly connected to the front side of the top railing 3 , and a sliding hole 16 for use with the slider 15 is opened on the front side of the bottom railing 2 , and the surface of the slider 15 contacts the inner cavity of the sliding hole 16 .

[0033] The above solution is adopted: by setting the slider 15 and the sliding hole 16, when the top railing 3 moves, the slider 15 will be driven to move along the inner cavity of the sliding hole 16. The coordinated use of the slider 15 and the sliding hole 16 has a limiting effect on the moving position of the top railing 3, so that the top railing 3 will not lose contact with the inner cavity of the bottom railing 2.

[0034] The working principle of this utility model:

[0035] When in use, when it is necessary to adjust the height of the handrail of the lifting platform 1 for construction, the user first pushes the control panel 7 toward the top. When the control panel 7 moves, the moving shell 12 will be driven to move along the surface of the moving block 13. When the control panel 7 moves, the extrusion rotating shell 10 will be driven to move. When the extrusion rotating shell 10 moves, it will be squeezed by the extrusion column 11. The extrusion rotating shell 10 subjected to the extrusion force will pass through the rotating shaft and rotate along the surface of the extrusion block 9. The extrusion rotating shell 10 will generate an extrusion force on the extrusion block 9. The extrusion block 9 subjected to the extrusion force will drive the two limiting shells to move away from each other. When the limiting shell moves, it will drive the stabilizing shell 802 to move along the surface of the stabilizing rod 803. When the stabilizing shell 802 moves, the force generated will make The spring 804 undergoes elastic deformation. When the limit block 801 is completely out of contact with the inner cavity of the limit groove 14, the fence 4 is pulled up and down. When the fence 4 moves, it will drive the adjusting column 6 to move along the inner cavity of the adjusting shell 5. When the fence 4 moves, it will drive the top railing 3 to move along the inner cavity of the bottom railing 2. When the top railing 3 and the bottom railing 2 are at a height suitable for the user, release the control panel 7. The restoring force generated by the spring 804 restoring its shape will drive the limit block 801 to be stuck into the inner cavity of the limit groove 14. The coordinated use of the limit block 801 and the limit groove 14 has a limiting effect on the position of the adjusting column 6, and has a limiting effect on the position of the fence 4 and the top railing 3. At this time, the railing height of the lifting platform 1 for construction is adjusted.

[0036] To sum up: the lifting device for construction, by setting the limit device 8, the limit block 801, the stabilizing shell 802, the stabilizing rod 803 and the spring 804, solves the problem that the lifting platform used in the existing construction is a device for rising and falling at a vertical height inside and outside a building. These platforms are usually composed of metal frames, working platforms, lifting mechanisms, guardrails and other components, and are used to provide a safe working platform for construction personnel and materials. Usually, the height of the guardrail is fixed. However, the height of the construction workers is different. If the height of the guardrail cannot be adjusted according to the height of the construction workers, it is easy for the guardrail to be too high to hinder the construction, and the guardrail is too low to cause the construction workers to fall. However, the lifting platform used in the existing construction does not have a component for adjusting the height of the guardrail.
