The working principle is as follows: as shown in fig. 1, the protection platform composed of the bearing surface mechanism 1 and the support mechanism 2 is installed on the upper portion of the hoistway, so that the upper portion of the hoistway can be covered, personnel can construct the protection platform, and meanwhile, the protection platform can prevent objects from falling off and causes personal injury to the personnel at the bottom of the hoistway. The platform can be used for a hoistway with a door buttress and a hoistway without a door buttress, and when the hoistway without a door buttress is not provided, the piece fixing frame 204 is respectively connected with the first base 202 and the second base 203 and then is propped by a mandril of a construction site; when a door stack exists, the fixing frame 204 is directly connected and fixed with the first base 202 and the second base 203.

As shown in fig. 6 and 7, the clamping groove 2011 on one side of the main beam 201 is inserted between the first limit ring 2032 and the second limit ring 2033 corresponding to the limit pipe 2030, then the main beam is flatly placed on the opposite side, the telescopic screw 2063 is rotated to adjust the distance between the first round pipe 2061 and the second round pipe 2062, namely, the distance between the first base 202 and the left end of the main beam 201 is adjusted, so that the left and right length of the platform is adjusted, the extension pedal 1042 on the upper portion of the first base 202 is pulled out and retracted in a matching manner, so that the exposed space between the first base 202 and the left end of the main beam 201 is shielded, and then the locking ring 2064 is rotated to abut against one end of the first round pipe 2061 or the second round pipe 2062, so that the effect of limiting the screw to continue rotating in one direction is achieved, and the screw is limited.

Because one end of the main beam 201 is clamped on the limiting pipe 2030, the main beam 201 can rotate around the limiting pipe 2030, and the traction support mechanism 205 positioned on one side of the second base 203 plays a role in tensioning the main beam 201, so that the clamping groove 2011 of the main beam 201 and the limiting pipe 2030 cannot be separated, and the risk of dropping the platform is prevented. During installation, the extending lengths of the stretching rods 20531 and the connecting rods 20513 are adjusted to enable the clamping grooves 2011 of the main beam 201 to be tightly attached to the limiting tubes 2030, and then the stretching rods 20531 are fixed through the fixing pins 20533, so that the angle between the movable rod 20521 and the main beam 201 cannot be changed, and the main beam 201 cannot be transversely moved. Can effectually avoid the dangerous condition that girder 201 right-hand member dropped.

As shown in fig. 1 and 8, after the platform is mounted, the support plate 2073 abuts against the side wall of the hoistway, the elastic support plate 2073 is brought into close contact with the inner wall of the hoistway by a spring, and the wedges 2074 are inserted into the through grooves of the sidebar 2072 through the slots to fix the sidebar 2072. Because the upper portion of the limiting anti-roll bar 2071 is connected with the anti-roll-over pedal 103, and the other pedals 1011 are connected with one side of the anti-roll-over pedal 103 after being connected with each other, the anti-roll-over pedal 103 can limit the roll-over of the pedals 1011, and then the platform can be effectively prevented from rolling over.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
