Abstract
The utility model belongs to a human body safety catch for the operation stuff working in high position. The original human body safety catch uses cable wire as a safe wire, because the array of the cable wire is confused and irregular, and easily rubs with the inner wall of the safety catch, and often split-level entangled when recycled, and the tail portion can not be completely received and the carrying is not convenient. The utility model comprises a housing, a central wheel that is arranged in the housing, a pullback spring, a pawl, a mainspring spring that is arranged in the inner cavity of the central wheel and a safe wire that is connected to the mainspring spring, wherein the central wheel is fixed in the housing via a central shaft, which is characterized in that the safe wire is a flat non-metallic strip, the lower end of the housing is provided with a rolling wheel, which reduces the abrasion between the safe wire and the inner wall in the housing, and dose not split-level entangled, and the recycle operation of the safe wire is more convenient, which reduces damage to human body when the drop height is comparatively big and the carrying is more convenient.
Description
[technical field]
The utility model relates to a kind of safety device of high-rise working personnel fall arrest, especially a kind of improved human body catching device.
[background technology]
In the prior art, the used safety rope of human body catching device is the rounded steel wire rope in cross section, its surface irregularity, fall into disarray is irregular in housing, easily rub mutually with the catching device inner walls, usually staggered floor winding during recovery, the afterbody of steel wire rope can not take in fully.Secondly, steel wire rope lacks flexibility, and when drop is bigger, easily human body is damaged.Once more, this kind human body catching device weight is big, carries inconvenience.In addition, the electric conductivity of steel wire rope is better, if danger is bigger during livewire work, the scope of application of catching device is little.
[summary of the invention]
The utility model is at the defective of prior art, its technical assignment provide a kind of abrasion few, reclaim convenient, human body is had certain protective role and human body catching device easy to carry.
The technical solution of the utility model is achieved in that a kind of improved human body catching device, comprise housing, place centre wheel, extension spring and ratchet in the housing, the clockwork spring and the safety rope that is connected on the clockwork spring of centering wheel inner chamber, centre wheel is fixed in the housing by central shaft, it is characterized in that safety rope is the nonmetal band of flat, the lower end of housing is provided with roller.Safety rope changes the nonmetal band of flat structure into by the steel wire rope of original rope-like constructed, and its flat structure is bigger to have reduced friction with inner walls, and nonmetal band can not twined by staggered floor, can reclaim fully.Nonmetal band is a flexible piece, have certain cushioning effect, has reduced the injury to human body when big of catching device drop.In addition, nonmetal band is formed by high-intensity fibrage, not only insulate but also intensity is arranged, and guarantees the safety of livewire work and human body.Roller can guarantee that safety rope pulls out or reclaim reposefully in housing.
Described a kind of improved human body catching device, the wheel rim spacing of the width of nonmetal band and centre wheel adapts, and roller is fixed by roller shaft and housing; The both sides of centre wheel are provided with ratchet, and the ratchet of centre wheel and click-fit make locking more stable, stressed more balance; The housing upper end is provided with one handle, and the setting of this handle makes catching device easy to carry.
As safety rope, the abrasion of safety rope and inner walls is little with the nonmetal band of flat for the utility model, can not twine by staggered floor, make the reclaimer operation of safety rope more convenient, has reduced the injury to human body greatly time of catching device drop, carries convenient.In addition, result of use is better.

[specific embodiment]
As shown in Figure 1, 2, 3, a kind of improved human body catching device is by housing 1, place centre wheel 2, extension spring 5 and ratchet 4 in the housing, clockwork spring 9, central shaft 3 nonmetally is with 7, be positioned at compositions such as the roller 6 of housing lower end and handle 8, centre wheel 2 is connected with housing 1 by central shaft 3, and the both sides of centre wheel 2 all are provided with ratchet 12, and ratchet 12 cooperates with ratchet 4 realizes that twin-lock ends, ratchet 4 is fixed on the inwall of housing by connecting shaft 10, in the inner chamber of clockwork spring 9 centerings wheel.Extension spring 5 one ends are fixed on the ratchet, and the other end is fixed on the inwall of housing.Nonmetally be with 7 to form by the braiding of high-intensity non-conductive fibre, safety belt on similar automobile, the aircraft, the wheel rim spacing of the width of nonmetal band and centre wheel adapts, nonmetal band can not twined by staggered floor on centre wheel, the one end is connected on the clockwork spring, the other end is connected with safety belt on being bundled in human body, and handle 8 is positioned at the upper end of housing.Roller 6 is fixed on the lower end of housing by roller shaft 11.
During use, the handle of housing upper end is connected with lifting rope, on can side's fixed thereon fixture, nonmetal band links to each other with safety belt on being bundled in human body, when human body moves up and down less than retro-speed, the power of the ratchet bump ratchet on the centre wheel is less, under the extension spring effect, the ratchet top is smoothly by ratchet, under the effect of clockwork spring, the nonmetal band of pulling out is in hemicompact always and opens state, can freely work.In case slipping, human body falls, under the effect of gravity, nonmetal band is pulled out rapidly, the centre wheel faster rotational speed, and the power of ratchet bump ratchet strengthens, overcome the pulling force of extension spring, the ratchet top is absorbed in the groove between the ratchet, as long as load exists, centre wheel can't rotate, nonmetal band can not be pulled out, thereby human body can not be dropped again.In case load is removed, under the effect of clockwork spring and extension spring, ratchet and ratchet will break away from automatically, can recover operate as normal again.
