Abstract
Protecting device of lift well, relate to the elevator shaft fall arrest energy dissipator of building engineering field, 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, the openend of arc spring steel disc upward, the two ends of arc spring steel disc are connected with keel frame respectively by fixed bearing, 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.The utility model also as ground shield, and can greatly reduce the protecting device of lift well of injured degree as interlayer protection after personnel fall by energy dissipating design.
Description
Technical field
The utility model 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 purpose of this utility model is to overcome the deficiencies in the prior art, provides 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 purpose of this utility model is achieved in that 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 utility model, 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 utility model: 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 utility model, 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.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is A direction view in Fig. 1.
Detailed description of the invention
As Fig. 1, shown in 2, for protecting device of lift well, comprise bar keel framework 4, keel 5 in the middle of welding in keel frame 4, linking springs mesh sheet 3 in bar keel framework 4, two i iron 1 are set in the below of spring mesh sheet 3, two arc spring steel discs 2 and two spirality damping springs 9 are all set between every root i iron 1 and spring mesh sheet 3, the openend of arc spring steel disc 2 upward, one end of arc spring steel disc 2 is connected with keel frame 4 respectively by the first fixed bearing 6, the other end is connected with middle keel 5 respectively by the second fixed bearing 8, each first fixed bearing 6 welds with keel frame 4 respectively, each second fixed bearing 8 welds with middle keel 5 respectively.Each spirality damping spring 9 is separately positioned on the below of corresponding arc spring steel disc 2, the upper end of spirality damping spring 9 is connected with the middle part of arc spring steel disc 2 by spring card 7, the lower end of spirality damping spring 9 is supported on i iron 1 by spring seat 10, and spring seat 10 is welded on i iron 1.
