Abstract
The invention discloses an elevator emergency buffering device. The elevator emergency buffering device comprises a rubber damp located on an elevator bottom board and limit blocks located above the rubber damp, a cavity is formed below the rubber damp, two walls are arranged in the cavity in parallel and provided with supporting columns for supporting the rubber damp, the two walls divide the cavity into a first cavity body in the middle and second cavity bodies in the two sides, the first cavity body is filled with sand, and the lower portion of the rubber damp is supported by a spring in the first cavity body. When an elevator is in a weight loss state, firstly the limit blocks are sheared, part of speed of an elevator pod is decreased, then the elevator pod collides with the rubber damp, the speed is decreased secondarily, then the rubber damp is forced to move downwards to extrude the sand, and as the walls are made of materials with poor intensity, the sand rapidly enters the second cavity bodies, and safety of people is ensured.
Description
Technical field
The present invention relates to a kind of lift appliance, be specifically related to a kind of urgent shock absorber of elevator.
Background technology
Along with the development of science and technology and the progress of society, skyscraper is found everywhere, and elevator more becomes the indispensable part of skyscraper.At present, the use of elevator is quite universal, elevator not only can fast speed upstairs manned or downstairs, and upper and lower floor transporting cargo can be travelled to and fro between, not only efficient but also convenient, time saving and energy saving, bring many convenience to the life of people.But, also there is potential safety hazard in the use of elevator: when the electrical motor of elevator runs out of steam, or time the hawser of elevator has broken, elevator can downward suddon drawdown, and when especially elevator soon lands, its speed has reached higher level, the people being arranged in elevator also obtains acceleration/accel large equally naturally, when elevator landing and earth surface in a flash, reach maximum to the impulsive force of human body, the life security of people is subject 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 urgent shock absorber of elevator, under elevator is in state of weightlessness, and the buffer action of limiting stopper and damping rubber, the safety of protection people.
Technical scheme: for solving the problems of the technologies described above, the urgent shock absorber of a kind of elevator of the present invention, comprise and be positioned at rubber damping on car-floor, be positioned at limiting stopper above rubber damping, cavity is provided with below rubber damping, parallelly in cavity be provided with two sides body of wall, two sides body of wall is provided with the pillar stiffener of support rubber damping, cavity is divided into and is positioned at the first middle cavity and the second cavity of both sides by two face walls, first cavity is built with sand, and the below of rubber damping is simultaneously by being positioned at the spring supporting of the first cavity.
As preferably, described limiting stopper has eight, each two, elevator four faces.
As preferably, the thickness of described rubber damping is 10cm.
As preferably, the height of described body of wall is that 20cm is high.
As preferably, the width of described second cavity is 1/3rd of the first cavity width.
Beneficial effect: the urgent shock absorber of a kind of elevator of the present invention; under elevator is in state of weightlessness; by first shearing limiting stopper; slow down the speed of a part of elevator car, then then elevator car hits on rubber damping, and secondary slows down; then rubber damping is forced to move down extruding sand; because body of wall is that the very weak material of intensity is made, sand is made to be filled with the second cavity fast, the safety of protection people.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, the urgent shock absorber of a kind of elevator of the present invention, comprise and be positioned at rubber damping 2 on car-floor, be positioned at limiting stopper 5 above rubber damping 2, cavity is provided with below rubber damping 2, parallelly in cavity be provided with two sides body of wall 4, two sides body of wall 4 is provided with the pillar stiffener of support rubber damping 2, cavity is divided into and is positioned at the first middle cavity and the second cavity of both sides by two face walls, first cavity is built with sand 3, and the below of rubber damping 2 is supported by the spring 6 being positioned at the first cavity simultaneously.
In the present invention, described limiting stopper 5 has eight, each two, elevator four faces, and the thickness of described rubber damping 2 is 10cm, and the height of described body of wall 4 is that 20cm is high, and the width of described second cavity is 1/3rd of the first cavity width.
When elevator is due under accident is in state of weightlessness; limiting stopper 5 is provided with below elevator car 1; limiting stopper 5 is provided with maximum shear stress; maximum shear stress is greater than for limiting stopper 5 when elevator car 1 falls to producing masterpiece; limiting stopper 5 is cut off; slow down the speed of a part of elevator car 1; then elevator car 1 hits on rubber damping 2; secondary slows down; then force rubber damping 2 to move down extruding sand 3, because body of wall 4 is that the very weak material of intensity is made, make sand 3 be filled with the second cavity fast; the safety of protection people, protects the safety of people.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles 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.
