Abstract
The utility model belongs to the technical field of security of operation of lift equipment, discloses a lift well falling protecting net which aims to overcome the shortcomings that an existing lift does not have any measures of reducing casualties degree once a person falls into a lift well. The lift well falling protecting net comprises a lift well, a well wall and a well bottom, wherein the well wall is arranged on the periphery of the lift well, the well bottom is arranged at the lower end of the lift well, and soft nets are mounted in the lift well, at the well bottom and facilities above the well bottom. The soft nets are mounted in frames which are connected with a slow descending mechanism. The lift well falling protecting net is suitable for installation of various lift wells.
Description
Technical field
The utility model relates to a kind of lift facility safe in operation technology, particularly relates to a kind of elevator hoistways anti-drop net.
Background technology
It is reported, recently in certain city of south China, occured that a cause takes a lift and the horrible disaster that causes.Mother of a youth has immature son in arms and wants to take a lift in the 6th buildings downstairs, after pressing the button on elevator doorway, a little while, elevator door has left, she has striden by a pin, but the inside is empty, and car does not get off, she and child fall the shaft bottom to elevator like this heavyly, as a result mother die, child's effracture.In general, according to the design of control system and the power system of elevator, the car of elevator does not arrive a certain aspect, and the elevator door of this layer can not opened automatically.But, because uneven to management and the maintenance level of concrete each elevator; The elevator that has exceeds the time limit tenure of use, and the elevator daily attention and the periodic inspection that have are not in place; The faults such as cause the computerized control system of elevator disorderly, control command is made mistakes, and perhaps the safety guard of elevator is malfunctioning just are prone to accidents.In the accident that relevant elevator occurs, although as above-mentioned the probability of generation is very little owing to elevator door is arrogated to oneself out the accident that sky falls of stepping on, the consequence of accident is extremely serious; Simultaneously, many people that take a lift are arranged, when entering, can't see the situation of front clearly owing to many reasons, as have child in arms, holding in both hands that tall and big article have blocked sight line or while walking later with the people takes leave of, the fight under way mobile phone has hindered sight forward sight etc., will increase the possibility that such accident occurs.Therefore, how to alleviate the consequence that such accident causes, should cause our attention.
Summary of the invention
In a single day the purpose of this utility model provides a kind of elevator hoistways anti-drop net, overcomes present elevator, when the people being arranged from the elevator hoistways falling accident, has the deficiency without any the measure that alleviates the injures and deaths degree.
The utility model is achieved by following technical proposals.
The utility model comprises the shaft bottom of elevator hoistways and the borehole wall on every side and lower end, in described elevator hoistways, described shaft bottom and the dress thereon facility above be provided with soft net, described soft net is loaded in the frame, described frame is connected with slow descending mechanism.Mentality of designing of the present utility model is to utilize described soft net to accept the human body that contingency is fallen, and simultaneously, described soft net is supported by described frame, can provide buffering in the moment of contact human body; And described frame be connected slow descending mechanism and connect, the buffering of longer dropping distance is provided.Generally all be equipped with in the shaft bottom of described elevator hoistways such as hard things such as car dedicated buffering springs, so, described soft net must be located at leave these hard things have essential safety distance the top; Car when the position that drops to described soft net, can press described frame to descend together in operational process, and then when car rose, described frame can accompany and rise until recover former height and position.Clearly, the utility model only just can work when car is higher than the elevator door that personnel fall.
For described slow descending mechanism, there are a variety of technology to adopt, preferred two kinds of the utility model, namely described slow descending mechanism is that extension spring, its lower end are connected with described frame, the upper end is loaded on the described borehole wall, quantity at least four, be distributed in described frame top around; Or described slow descending mechanism is that spring, its upper end are connected with described frame, the lower end is loaded on the described shaft bottom, quantity is at least four, be distributed in below the described frame around.Because contacting of described frame and lift car is very frequent, and be not frayed for protecting described frame, is provided with four uniform car blocks above described frame, and captives joint with described frame.
Against existing technologies, the beneficial effects of the utility model are:
When the generation personnel occur from the elevator falling accident because of a variety of causes, can greatly improve the possibility of avoiding the personnel death; And can effectively alleviate personnel's injured degree.
Description of drawings
Fig. 1 is that slow descending mechanism described in the utility model is the structural representation of extension spring, Fig. 2 be the A of Fig. 1 to view, Fig. 3 is that slow descending mechanism described in the utility model is the structural representation of spring.Among the figure: 1, elevator hoistways, 2, the borehole wall, 3, the shaft bottom, 4, soft net, 5, frame, 6, extension spring, 7, spring, 8, the car block.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing and the specific embodiment.
In the utility model, frame 5 should adopt the material of higher-strength to make, and enough supports can be arranged when soft net 4 is stressed; Soft net 4 should adopt soft and whippy thread like material braiding to form; Extension spring 6 or spring 7 should have corresponding permission stretching or compression distance according to specific design, and formed impulsive force when having enough intensity to cushion powerful personnel in this distance to drop; Car block 8 is because frequently contacting with the car bottom, and is easy to wear, should be convenient to change.At ordinary times, when cage descending when the installation site of the present utility model, the utility model just descends together, and then rises until original position with car; When car moves at high level, and any height between car and the utility model is when having the people unfortunately to fall, namely at first contact soft net 4, and cushion, then powerful impulsive force passes to extension spring 6 or spring 7 by soft net 4 by frame 5, under the effect of corresponding pulling force or elastic force, at the enterprising row buffering of a segment distance, greatly alleviated the suffered strength under shock of human body.
