Abstract
The invention discloses an elevator shaft protecting device and relates to an elevator shaft anti-falling energy dissipating device in the building engineering field. The elevator shaft protecting device comprises a rectangular keel framework, a spring mesh is connected to the interior of the rectangular keel framework, two pieces of I-shaped steel are arranged below the spring mesh, an arc-shaped spring steel sheet and a spiral damping spring are arranged between each piece of I-shaped steel and the spring mesh, the open end of each arc-shaped spring steel sheet faces upwards, the two ends of each arc-shaped spring steel sheet are connected with the keel framework through fixed supporting bases respectively, and each fixed supporting base is welded to the keel framework. The spiral damping springs are arranged below the arc-shaped spring steel sheets, the upper ends of the spiral damping springs are connected with the middles of the arc-shaped spring steel sheets through spring clamping sheets, the lower ends of the spiral damping springs are supported on the I-shaped steel through spring bases, and the spring bases are welded to the I-shaped steel. The elevator shaft protecting device can be used for both interlayer protection and bottom layer protection, and the injury degree can be greatly relieved due to energy dissipation design after people fall.
Description
Technical field
The present invention relates to the elevator shaft fall arrest energy dissipator of building engineering field.
Background technology
In construction work, all will indwelling elevator shaft in advance, if fail well protection, may cause casualties, bring great potential safety hazard to construction, and existing safeguard procedures have a variety of, all rely mainly on prevention, if do not consider to have an accident, how to reduce the degree of injury to personnel evil, general way is that scaffold is up progressively up set up from bottom, interlayer fixed form or protective screening.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, providing a kind of tool degree high, also as ground shield, and after personnel fall, can greatly reduce the protecting device of lift well of injured degree by energy dissipating design as interlayer protection.
The object of the present invention is achieved like this: protecting device of lift well, comprise bar keel framework, linking springs mesh sheet in bar keel framework, two i iron are set in the below of spring mesh sheet, arc spring steel disc and spirality damping spring are all set between every root i iron and spring mesh sheet, upward, the two ends of arc spring steel disc are connected with keel frame respectively by fixed bearing in the openend of described arc spring steel disc, and each fixed bearing is welded on keel frame respectively; Described spirality damping spring is arranged on the below of arc spring steel disc, the upper end of spirality damping spring is connected by the middle part of spring card with arc spring steel disc, the lower end of spirality damping spring is supported on i iron by spring seat, and spring seat is welded on i iron.
As improvement of the present invention, described arc spring steel disc has four, spirality damping spring has four, wherein two arc spring steel discs, two spirality damping springs are arranged between an i iron and spring mesh sheet, and two other arc spring steel disc, two spirality damping springs are arranged between another root i iron and spring mesh sheet; Keel in the middle of welding in described keel frame, the fixed bearing of each arc spring steel disc one end welds with middle keel respectively.
Operating procedure of the present invention: 1, hoistway wall both sides reserved opening;
2, on i iron, weld spring seat, i iron is passed across reserved opening;
3, damping spring rotation is fixed on spring seat;
4, with square tube or steel-pipe welding center bar keel framework, and be welded with one keel in centre, surrounding is gathered spring mesh sheet;
5, on center bar keel, appointed part is welded and fixed bearing respectively;
6, first spring card is fixed on bottom spring steel plate and forms entirety, then this entirety is snapped in spring fixed bearing;
7, damping spring is connected by spring card with spring steel plate.
The present invention, by spring mesh sheet, spring steel plate, the triple energy dissipating design of damping spring, has following characteristics:
1, the assembling of tool can be raised labour efficiency;
2, interlayer is arranged and can be saved lot of materials and labour cost with setting up from bottom compared with scaffold;
3, closed protective design can effectively occur by Accident prevention, just in case the energy dissipating design having accident that this device occurs also can reduce injury to personnel degree greatly;
4, not only solve anti-problem, personnel when having an accident that more fundamentally solve fall and cause injured and problem that is that die.
