the specific structure of the integral hoisting protection frame of the special-shaped courtyard is shown in figures 1 to 3 and comprises a protection frame platform 1, a falling prevention device 2, an anti-overturning device 3, a hoisting mechanism 4 and a damping device 5.

The cross section shape of the protective frame platform 1 is matched with the shape of the special-shaped patio in the construction area, so that the protective frame platform can slide up and down in the special-shaped patio along with the lifting device 4, not only can be used for standing construction of workers, but also can prevent the workers or sundries from falling from the special-shaped patio. The anti-falling device 2 comprises a support plate 21 and a spring 23, the support plate 21 is rotatably installed at the edge position of the protection frame platform 1 through a rotating shaft 22, one end of the spring 23 is connected to the protection frame platform 1, and the other end of the spring 23 is connected to the support plate 21.

The protective frame platform 1 comprises an upper extension block 11 formed by extending outwards. The upper extension block 11 is used for limiting the rotation of the support plate 21 and enabling the support plate 21 to support and position the protection frame platform 1 at a selected flat position for operation. The upper end of the spring 23 is fixed to the upper extension block 11. When the support plate 21 is rotated downwards to the limit position, the connection point of the spring 23 and the support plate 21 is closer to the inner side of the protection frame platform 1 than the connection point of the spring 23 and the upper extension block 11, so that after the support plate 21 is manually rotated to the downward limit state, the acting force exerted by the spring 23 on the support plate 21 has the tendency of enabling the support plate 21 to continue to rotate downwards, therefore, the support plate 21 can be fixed at the lower limit position without rotating reversely, the utility model can be lowered to the designated height through the lifting mechanism 4, and the spring 23 forms a locking structure for fixing the support plate 21 at the lower limit position. In other embodiments, the locking structure may further include an active magnet mounted on the lower end of the supporting plate 21 and a passive magnet mounted on the side of the protection frame platform 1, in which case the distance between the connection point of the spring 23 on the supporting plate 21 and the protection frame platform 1 may be equal to or less than the distance between the connection point of the spring 23 on the upper extension block 11 and the protection frame platform 1.

In this embodiment, the upper end of the supporting plate 21 is provided with a groove for installing the spring 23, and the outer end of the upper extension block 11 exceeds the groove, so that the extrusion of the supporting plate 21 and the upper extension block 11 to the spring 23 can be reduced, and the service life of the spring 23 can be prolonged. In other embodiments, the recess may be omitted and the spring 23 may be directly attached to the upper end surface of the support plate 21, but in this case, the distance between the upper end surface of the support plate 21 and the upper extension block 11 needs to be increased appropriately.

The side surface of the protective frame platform 1 is provided with a T-shaped groove 12, a lower clamping block 13 is installed in the T-shaped groove 12 in a guiding and sliding manner, the outer end of the lower clamping block 13 extends outwards to form the corresponding side surface of the protective frame platform 1, and the shape of the lower clamping block 13 is matched with that of the T-shaped groove 12. When the protective frame is in a use state, the lower fixture block 13 slides along the T-shaped groove 12 to be positioned at the lower end of the support plate 21, so that the support plate 21 can be protected, the support plate 21 can be supported by the lower fixture block 13 and cannot be directly separated from the protective frame platform 1 after the joint of the support plate 21 and the protective frame platform 1 is broken, and the use safety of the protective frame is further guaranteed.

The shape of the lower fixture block 13 is matched with the shape of the T-shaped groove 12, the lower fixture block 13 can be inserted into the T-shaped groove 12 from the end part of the T-shaped groove 12 along the extending direction of the T-shaped groove 12, and the lower fixture block 13 can not be separated from the T-shaped groove 12 when being applied with a force vertical to the extending direction of the T-shaped groove 12. The structure is beneficial to ensuring the strength of the joint of the lower clamping block 13 and the protective frame platform 1. In other embodiments, the lower fixture block 13 may also be mounted on the protection frame platform 1 by matching with other guiding and moving structures such as a shaft and a shaft sleeve, as long as the lower fixture block 13 can be translated to the lower side of the support plate 21 and can also be translated to be staggered with the support plate 21.

In this embodiment, the outer end surface of the lower latch 13 is flush with the outer end surface of the upper extension block 11, so as to increase the safety of the lower latch 13. In other embodiments, the outer end surface of the lower latch 13 may also extend beyond the outer end surface of the upper extension block.

When the lifting mechanism 4 drives the protection frame platform 1 to ascend, the building structures 6 around the protection frame platform 1 apply downward acting force to the supporting plate 21, the supporting plate 21 overcomes the elasticity of the spring 23 and is folded towards the inner side, and the protection frame platform 1 can cross the building structures 6 and ascend to the flat-bed position where operation is needed. When backup pad 21 no longer receives building structure 6 extrusion all around, spring 23 drives backup pad 21 and resets, and backup pad 21 resumes straight state in order to support on building structure 6 all around to fix protection frame platform 1 in the flat bed position department that needs to act on.

The overturn preventing device 3 comprises a connecting rod, the upper end of the connecting rod is hinged to the side face of the protection frame platform 1, the connecting rod comprises a supporting portion of the lower end, the supporting portion comprises a supporting face matched with the shape of the upper end of the building structure 6 in shape, and the supporting portion is provided with a bolt hole. When construction needs to be carried out at a certain floor position, the connecting rod is unfolded to enable the supporting surface to be supported on the building structure 6, and then expansion bolts are installed in the bolt holes to fix the connecting rod. The anti-toppling device 3 can further improve the safety of use of the present invention. The supporting surface matched with the upper end of the building structure 6 in shape can increase the contact area between the supporting part and the building structure 6, reduce the pressure applied on the building structure 6 and enable the supporting to be more stable. In other embodiments, the overturn preventing device 3 can be omitted, which does not affect the supporting plate 21 to support and position the protection frame platform 1 at the desired flat position.

The lifting mechanism 4 is a winch, a winding drum of the winch is installed on the building structure 6 on the top layer, and a steel wire rope head is fixed at the upper end of the protective frame platform 1. Damping device 5 includes first shock pad 51 and second shock pad 52, and first shock pad 51 is fixed the lower extreme of backup pad 21, its effect is in protection frame platform 1 direct contact building structure 6 all around when tenesmus to reduce the impact to building structure 6, ensure building structure 6's safety. The second shock pad 52 is fixed on the upper end surface of the lower fixture block 13 to absorb the impact between the lower fixture block 13 and the support plate 21 during the failure, so as to reduce the deformation of the lower fixture block 13; meanwhile, the second shock absorption pad 52 can enable the lower fixture block 13 to be in closer contact with the support plate 21 in a failure, so that the stress area of the lower fixture block 13 is increased, and the use safety of the lower fixture block 13 is further improved.
