Abstract
The invention discloses an elevator emergency falling protection device, which comprises support plates, bosses and springs, wherein the bosses and the springs are uniformly arranged and fixed on an elevator bottom plate; the support plates are paved on the elevator bottom plate and supported by the bosses; the springs are in free states; and the top ends of the springs are contacted with the bottom surfaces of the support plates. The elevator emergency falling protection device is ingenious in thought and simple in structure. The conventional elevator can be reformed, and the reformed elevator seems the same as the common elevator; people entering the elevator directly stand on the support plates, the carrying capacity of the support plates is consistent with the natural carrying capacity of the elevator, and the elevator can work normally; once the elevator fails and falls in emergency, especially when the elevator bottom plate contacts the ground and brings great impact to the bosses, the bosses can be shear off, the acceleration can be reduced partially, and the elasticity of the springs can provide buffering powder for the support plates, so that the impact of external force to human bodies is reduced, and the life safety of the people is effectively ensured.
Description
Technical field
The present invention relates to a kind of safety guard that is used on the elevator, be specifically related to a kind of elevator emergency landing fender guard.
Background technology
Along with the progress of development of science and technology and society, skyscraper is found everywhere, and elevator more becomes the indispensable part of skyscraper.At present, the use of elevator is quite universal, and elevator is not only can fast speed manned upstairs or downstairs, and can travel to and fro between floor shipping goods up and down, not only efficiently but also convenient, time saving and energy saving, brings many convenience for people's life.But, also there is potential safety hazard in the use of elevator: when the electrical motor of elevator runs out of steam, when perhaps the hawser of elevator has broken, elevator can land downwards rapidly, and when especially elevator soon landed, its speed had reached higher level, the people who is arranged in elevator also obtains same big acceleration/accel naturally, when elevator landing contacts in a flash with ground, the impulsive force of human body is reached maximum, people's life security is subjected to serious threat.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art; the invention provides a kind of elevator emergency landing fender guard; when elevator cable has broken or electrical motor when running out of steam, make elevator when landing, obtain buffer action, thus protection people's life security.
Technical scheme: for achieving the above object; a kind of elevator emergency landing fender guard that provides of the present invention; comprise stay bearing plate, boss and spring; described boss and spring are evenly arranged and are fixed on the elevator base plate; described stay bearing plate is laid on the elevator base plate and by boss and supports; described spring is a free state, and the top of spring contacts with the bottom surface of stay bearing plate.
As preferably, described boss is the box-shaped boss, and the height of boss is 10～30cm; In order to make stay bearing plate stressed even, the number of described boss is five, and five boss lay respectively at the center of the midway location and the elevator base plate on four limits of elevator base plate; The number of described spring is four, and four springs lay respectively at four corner positions of elevator base plate.Spring of the present invention is a purpose made, and through special processing, spring force is bigger, and spring is in the free state that does not stress at ordinary times.
Beneficial effect: a kind of elevator emergency landing fender guard of the present invention, be skillfully constructed, simple in structure, can on the basis of existing elevator, reequip, make elevator seem do not have difference with conventional lift, the people who enters elevator directly stands on the stay bearing plate, and the load-carrying of stay bearing plate is consistent with the natural load carrying ability of elevator, and elevator can normally use; In case elevator runs into the fault forced landing, especially when bringing enormous impact power to boss behind the elevator base plate kiss the earth, boss can be cut off, acceleration/accel can reduce a part, the effect of spring force can be given cushion effect of stay bearing plate then, thereby reduce the impact that external force causes the person, effectively guarantee people's life security.
Description of drawings
Fig. 1 structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
As shown in Figure 1; a kind of elevator emergency landing fender guard of the present invention; comprise stay bearing plate 1, boss 2 and spring 3; boss 2 and spring 3 are evenly arranged and are fixed on the elevator base plate 4; stay bearing plate 1 is laid on the elevator base plate 4 and by boss 2 and supports; spring 3 is a free state, and the top of spring 3 contacts with the bottom surface of stay bearing plate 1.
In the present embodiment, boss 2 is the box-shaped boss, and the height of boss 2 is 10～30cm; The number of boss 2 is five, and five boss 2 lay respectively at the center of the midway location and the elevator base plate 4 on 4 four limits of elevator base plate, can have bigger bearing capacity so that stay bearing plate 1 is stressed even like this; The number of spring 3 is four, and four springs 3 lay respectively at 4 four corner positions of elevator base plate.The spring 3 that present embodiment adopted is purpose mades, and through special processing, spring 3 elasticity rates are bigger, and spring 3 is in the free state that does not stress at ordinary times; Just can be cut off when the boss 2 of present embodiment only is subjected to bigger impulsive force, boss 2 just ruptures at great friction stress can be given through calculating, and makes boss 2 can bear corresponding friction stress when making then.
A kind of elevator emergency landing fender guard of the present invention; can on the basis of existing elevator 5, reequip; make elevator 5 seem do not have difference with conventional lift; the people who enters elevator 5 directly stands on the stay bearing plate 1; the load-carrying of stay bearing plate 1 is consistent with the natural load carrying ability of elevator 5, and elevator 5 can normally use.When elevator 5 sudden failure in use, cause elevator 5 to land rapidly, its speed has reached higher level when elevator 5 soon lands, and the time that contacts with ground when landing is extremely of short duration, and 5 the people of taking a lift also can obtain same big acceleration/accel; The impulsive force that boss 2 is subjected to is during greater than the limit stress of boss 2, boss 2 is cut off, make people's speed reduce a part, then under the effect of spring 3 spring forces, the acceleration/accel of stay bearing plate 1 can slowly reduce, the impact that the people is subjected in this process can not work the mischief to life in the scope that can bear.
The above only is a preferred implementation of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
