[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In the present invention, the first air cylinder pushes the first telescopic rod to expand and contract with the mounting plate. A shock-absorbing roller assembly is welded to the outside of the first telescopic rod. Extending and contracting the first telescopic rod makes the shock-absorbing roller assembly fit the construction wall surface, enabling the high-rise steel structure construction protection platform to be not easily shaken, thus having good stability and not affecting the construction due to shaking, reducing the construction difficulty. Moreover, the T-shaped sleeve and the T-shaped rod form an elastic structure through the small spring, and the roller body welded to the outside of the T-shaped rod fits the wall surface at the construction site.

[0017] 2. In the present invention, the second air cylinder pushes the second telescopic rod to expand and contract with the mounting plate. A motor housing is welded to the outside of the second telescopic rod, and the motor body in the motor housing drives the wheels to rotate, enabling the high-rise steel structure construction protection platform to move left and right, facilitating the staff to accurately reach the construction position. At the same time, it avoids the staff being unable to accurately reach the construction position and using some difficult construction actions, thus facilitating the staff to construct. Moreover, it can adapt to the uneven construction wall surface by extending and contracting the second telescopic rod, and a layer of motor sound insulation cotton is wrapped on the inner wall of the motor housing, effectively eliminating the noise generated during the operation of the motor body.

[0018] 3. In the present invention, the hoisting rope of the crane passes through the pulley to move the high-rise steel structure construction protection platform up and down. The convex block is movably connected to the pulley. When the pulley rotates at a low speed, the magnetic block adsorbs the convex block. When the pulley rotates at an excessive speed, the convex block disengages from the magnetic block due to inertia and the convex block is stuck in the groove of the mounting block. During the use of the high-rise steel structure construction protection platform, when problems such as power failure and malfunction occur to the high-rise steel structure construction protection platform, the pulley can be locked in time to stop the rope from paying out, preventing the high-rise steel structure construction protection platform from falling, effectively ensuring the safety of the high-rise steel structure construction protection platform and not allowing problems such as potential safety hazards to occur to the high-rise steel structure construction protection platform, thus ensuring the safety of the staff.

[0019] 4. When an object falls from a height and hits the high-rise steel structure construction protection platform of the present invention, it will be blocked by the concave top plate. The upper and lower ends of the damper assembly are respectively welded with support rods and the concave top plate. The nut and the damper body form an elastic structure through a large spring, so as to greatly absorb the impact force generated by the falling object and avoid the back-and-forth oscillation of the falling object at the same time. The damper body and the nut are connected by threads. Rotating the nut can push the large spring to extend or compress, changing the softness and hardness of the damper assembly, so that it can be applied to a variety of construction environments.

[0020] 5. A plurality of suction nozzles are fixedly arranged at equal intervals below the chamber shell of the present invention. The suction fan body in the suction fan housing is installed on one side of the chamber shell. When the suction fan body is started, the suction nozzles suck in dust, realizing that the high-rise steel structure construction protection platform can automatically reduce and absorb the dust formed in the surrounding environment during use, avoiding the excessive dust concentration generated by the surrounding construction environment from harming the health of the staff, improving the use safety of the high-rise steel structure construction protection platform, and the plurality of suction nozzles can disperse the wind force, making the dust absorption range wide and improving the dust absorption quality.

The shock-absorbing roller assembly 6 is welded to the outside of the first telescopic rod 5. Extending and retracting the first telescopic rod 5 makes the shock-absorbing roller assembly 6 fit the construction wall surface, enabling the high-rise steel structure construction protection platform to be not easily shaken, thus having good stability, not affecting the construction due to shaking, reducing the construction difficulty. And the T-shaped sleeve 601 and the T-shaped rod 603 form an elastic structure through the small spring 602. The roller body 604 welded to the outside of the T-shaped rod 603 is in contact with the construction wall surface. During the movement of the high-rise steel structure construction protection platform, the bumps generated by the uneven wall surface can be filtered, making the high-rise steel structure construction protection platform move smoothly;

[0033] A second telescopic rod 7 is installed at the rear end of the second cylinder 4, and a motor housing 8 is fixed at the rear end of the second telescopic rod 7.

A telescopic structure is formed between the second telescopic rod 7 and the mounting plate 2, and a welded integrated structure is formed between the second telescopic rod 7 and the motor housing 8. And the central axis of the motor housing 8 coincides with the central axis of the motor sound insulation cotton 9. A wheel 11 is installed below the motor body 10. The second cylinder 4 pushes the second telescopic rod 7 to extend and retract with the mounting plate 2. The motor housing 8 is welded to the outside of the second telescopic rod 7. The motor body 10 in the motor housing 8 drives the wheel 11 to rotate, so that the high-rise steel structure construction protection platform can move left and right, facilitating the staff to accurately reach the construction position. At the same time, it avoids the situation that the staff cannot accurately reach the construction position and use some difficult construction actions, thus facilitating the staff to construct. And it can be adapted to the uneven construction wall surface by extending and retracting the second telescopic rod 7. And a layer of motor sound insulation cotton 9 is wrapped on the inner wall of the motor housing 8, effectively eliminating the noise generated when the motor body 10 operates;

[0034] On both sides of the construction protection platform frame 1, there are fixed locking components 12. The locking components 12 include mounting blocks 1201, bearings 1202, pulleys 1203, magnetic blocks 1204, and convex blocks 1205. Inside the mounting block 1201, there is a fixed bearing 1202. On the inner wall of the bearing 1202, there is a pulley 1203. Inside the pulley 1203, there is a fixed magnetic block 1204. And outside the magnetic block 1204, there is a convex block 1205. The bearing 1202 is fixedly connected to the mounting block 1201. And the bearings 1202 are symmetrically distributed along the central axis of the pulley 1203. And the central axis of the pulley 1203 coincides with the central axis of the mounting block 1201. The magnetic block 1204 is fixedly connected to the pulley 1203.

When the pulley 1203 rotates at a low speed, the magnetic block 1204 adsorbs the convex block 1205. When the pulley 1203 rotates at an excessive speed, the convex block 1205 disengages from the magnetic block 1204 due to inertia. The convex block 1205 is stuck into the slot of the mounting block 1201. During the use of the high-rise steel structure construction protection platform, when problems such as power failure or malfunction occur to the high-rise steel structure construction protection platform, the pulley 1203 can be locked in time to stop the rope from paying out, preventing the high-rise steel structure construction protection platform from falling, effectively ensuring the safety of the high-rise steel structure construction protection platform, and preventing problems such as potential safety hazards from occurring to the high-rise steel structure construction protection platform, thus ensuring the safety of the staff;

[0035] Above the construction protection platform frame 1, there is a support rod 13 fixed. And above the support rod 13, there is a damper assembly 14 arranged. Above the damper assembly 14, there is a concave top plate 15 fixed. The damper assembly 14 includes a damper body 1401, a nut 1402 and a large spring 1403. The nut 1402 is installed outside the damper body 1401, and above the nut 1402, there is a large spring 1403 arranged. Between the damper body 1401 and the nut 1402, there is a threaded connection. And the nut 1402 and the damper body 1401 form an elastic structure through the large spring 1403. And the central axis of the large spring 1403 coincides with the central axis of the damper body 1401.

The nut 1402 and the damper body 1401 form an elastic structure through the large spring 1403, so as to greatly absorb the impact force generated by the falling object and avoid the falling object from oscillating back and forth at the same time. Between the damper body 1401 and the nut 1402, there is a threaded connection. Rotating the nut 1402 can push the large spring 1403 to extend or compress, changing the softness and hardness of the damper assembly 14, so that it can be applicable to various construction environments;

[0036] Below the concave top plate 15, a chamber shell 16 and a suction fan housing 17 are arranged in sequence from left to right. And below the chamber shell 16, a suction nozzle 18 is fixed.

And the plurality of suction nozzles 18 can disperse the wind force, making the dust absorption range wide and improving the dust absorption quality.

[0037] In summary, when using the construction protection platform for high-rise steel structures with a stable structure, the hoist rope passes through the pulley 1203 to move the construction protection platform for high-rise steel structures up and down. When there are problems such as power failure or malfunction in the construction protection platform for high-rise steel structures, the convex block 1205 is movably connected to the pulley 1203. When the pulley 1203 rotates at a low speed, the magnetic block 1204 adsorbs the convex block 1205. When the pulley 1203 rotates at an excessive speed, the convex block 1205 separates from the magnetic block 1204 due to inertia, and the convex block 1205 is stuck into the groove of the mounting block 1201, which can lock the pulley 1203 in time to prevent the construction protection platform for high-rise steel structures from falling. The first cylinder 3 pushes the first telescopic rod 5 and the mounting plate 2 to expand and contract. A shock-absorbing roller assembly 6 is welded to the outside of the first telescopic rod 5. Extending and contracting the first telescopic rod 5 makes the shock-absorbing roller assembly 6 fit the construction wall surface, making the construction protection platform for high-rise steel structures not easy to shake. And the T-shaped sleeve 601 and the T-shaped rod 603 form an elastic structure through the small spring 602. The roller body 604 welded to the outside of the T-shaped rod 603 fits the wall surface at the construction site. The bumps generated by the uneven wall surface can be filtered during the movement of the construction protection platform for high-rise steel structures. The second cylinder 4 pushes the second telescopic rod 7 and the mounting plate 2 to expand and contract. A motor housing 8 is welded to the outside of the second telescopic rod 7. The motor body 10 in the motor housing 8 drives the wheel 11 to rotate, enabling the construction protection platform for high-rise steel structures to move left and right. And a layer of motor sound insulation cotton 9 is wrapped on the inner wall of the motor housing 8, which can eliminate the noise generated when the motor body 10 operates. When an object falls from a height hits the construction protection platform for high-rise steel structures, it will be blocked by the concave top plate 15. The upper and lower ends of the damper assembly 14 are respectively welded with a support rod 13 and a concave top plate 15. The nut 1402 and the damper body 1401 form an elastic structure through the large spring 1403, so as to greatly absorb the impact force generated by the falling object. And the damper body 1401 and the nut 1402 are connected by threads. Rotating the nut 1402 can push the large spring 1403 to extend or compress, so that the softness and hardness of the damper assembly 14 can be changed. A plurality of suction nozzles 18 are equidistantly fixed below the chamber shell 16. The suction fan body 20 in the suction fan housing 17 is installed on one side of the chamber shell 16. When the suction fan body 20 is started, the chamber shell 16 is in a negative pressure state, and the suction nozzles 18 suck in dust, and the suction fan body 20 discharges the sucked dust into the dust collection box 21.
