Background
A series of suspension type construction platforms comprising a construction elevator, a construction hanging basket and a lifting frame are indispensable construction equipment during aloft work. The principle of this kind of construction equipment is similar to a common car elevator, but because it belongs to temporary construction equipment, the reliability is some low, and can not accomplish the full seal (otherwise can not be constructed). Therefore, the construction equipment is required to be equipped with a safety rope, the upper end of the safety rope is bound on a fixed point, and a constructor is connected with the safety rope through a safety lock (also known as a safety catcher). When a falling accident occurs, the safety lock slides on the safety rope at a high speed, so that a locking structure of the safety lock is triggered, and constructors are hung on the safety rope.
However, the position adjacent to the construction surface is often short of the fixing point of the safety rope, so that in order to install the safety rope, the fixing point needs to be found at a far place, and a long safety rope needs to be used. Therefore, the safety rope is very troublesome to install, the situation that the length of the safety rope is not enough is easy to occur, and the safety rope is easy to wind and knot when in use.

Detailed Description
As shown in fig. 1-3, a personnel fall buffer system for a suspended construction platform for ensuring safety of constructors in the absence of safety rope fixing points on site, the suspended construction platform 1 comprises a construction elevator, a construction basket or a hoisting frame; the personnel falling buffer system comprises a safety frame 3 which vertically penetrates through the suspension type construction platform 1 and is in sliding connection with the suspension type construction platform 1, and a bungee cord 2 of which the upper end is bound at the top of the safety frame 3 and the lower end is bound on a constructor;
note that the bungee cord 2 cannot be replaced by a conventional cord, which has poor elasticity and cannot play a role in buffering when a constructor falls to the ground at a high speed, so that the constructor can be directly injured or even killed.
The position of safety frame 3 and suspension type construction platform 1 contact is provided with the locking device who is used for preventing safety frame 3 and suspension type construction platform 1 to take place relative slip, and locking device is the connecting piece that can break off with safety frame 3 after suspension type construction platform 1 falls to earth.
The sliding connection ensures that the constructor has enough buffer distance after the safety frame 3 falls to the ground by matching with a locking device which is disconnected after falling to the ground. The buffer distance is cut off a lot if the safety gear 3 is fixed to the suspended construction platform 1 and the locking device cannot be disconnected. Without a locking device, the bungee cord 2 can easily get entangled with construction materials on the suspended construction platform 1, which not only affects normal construction, but also can not be used normally after an accident.
The height of the safety frame 3 is marked as H, the maximum vertical distance between the upper end and the lower end of the bungee cord 2 in the state that the bungee cord 2 is loosened is marked as a, the vertical distance between the bottom of a constructor and the ground after the suspension type construction platform 1 falls to the ground is marked as b, the maximum operation height of the suspension type construction platform 1 is marked as H, and then H is larger than H/20+ a + b, and H-a-b is not smaller than 1 meter.
Here, a is a rope length when only one bungee cord 2 is provided, and the bungee cord 2 needs to be straightened and then actually measured when a plurality of bungee cords 2 are provided. The bungee cord 2 is a bungee cord, and the relaxed state refers to a state when the bungee cord is not extended. h-a-b is a buffer distance, a meter of buffer distance is reserved for each working height of 20 meters, and in the conservative calculation, even if a constructor weighing 100 kilograms uses only one conventional bungee jumping rope 2, the buffer distance is less than two thirds. In the use scene referred to in this application, the constructor is foot-down, and even if the buffer distance is used up and the speed of the constructor is not reduced to 0, the constructor will not cause casualty.
The locking device is a plastic screw which is horizontally penetrated through the safety frame 3 and then is nailed on the suspended construction platform 1. The plastic screws are not directly nailed to the safety frame 3 but are arranged through the ear plates on the safety frame 3 to avoid the safety frame 3 from being broken.
In this embodiment, the safety shelf 3 is a portal support, and includes two uprights and a cross bar, and the bottom plate is fixed to the horizontal anchor of the lower end of the upright. The vertical rod and the cross rod are formed by bending the same round steel, and reinforcing rib plates which are respectively welded with the vertical rod and the cross rod and used for preventing the vertical rod and the cross rod from being disconnected when falling are arranged at the bending positions. The two points are combined, so that the connecting position of the vertical rod and the cross rod is prevented from being broken after falling.
In this embodiment, each constructor binds two bungee jumping ropes 2 with the same length, and the required buffer distance can be reduced by the two ropes. The upper ends of the two bungee jumping ropes 2 are respectively bound on the cross bars of the two different safety racks 3 and are connected with the cross bars in a sliding way. The sliding connection here can reduce the required length of the bungee cord 2.
The lower end of the bungee cord 2 is bound on a whole safety sling of a constructor, so that the constructor is prevented from being injured.
The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
