Abstract
The utility model discloses a rope grabbing descent control device which comprises an upper hinge and a lower hinge, wherein the upper hinge is fixedly connected with the lower hinge by a preloading bolt, the inner part of the upper hinge and the inner part of the lower hinge are matched semi-cylindrical cavities, the upper hinge is provided with a blocking trough, a brake handle is arranged above the upper hinge and is clamped in the clamping trough by a fixture block matched with the size of the blocking trough on the upper hinge, and a safety belt is arranged below the lower hinge. The rope grabbing descent control device of the utility model has simple structure, light weight, high safety and wide applicable range of crowd. Because the rope grabbing descent control device can be folded and closed like the hinge, and a plurality of rope grabbing descent control devices can be hung on one life line so as to greatly improve life saving efficiency.
Description
Technical field
The utility model belongs to the lifesaving appliance technical field, is specifically related to a kind of rope descending lifeline of grabbing.
Background technology
At present commercially available descending lifeline mainly can be divided into two classes, and a class is the descending lifeline of using in the rock climbing, as 8 word rings etc.For this class descending lifeline, must just can grasp using method and skill through training to a certain degree, the general masses can't use.Another kind of is the life saving descending lifeline, can use for ruck.What time not enough life saving descending lifeline ubiquity is following at present:
(1) descending lifeline that has must fix near the window of building because volume and weight is bigger than normal in advance.But when the fire location of building by chance below the descending lifeline position, then this descending lifeline can't be avoided fire location, so can't use.
(2) most of descending lifeline in use, human body is an end that hangs over life line, life line passes descending lifeline, the moving parts of descending lifeline inside is more.JSH100/35 series descending lifeline as certain company produces just belongs to this class.In the decline process, in case descending lifeline internal motion part breaks down, life line can be by clamping stagnation in descending lifeline, and the personnel that then descend can be suspended in the air, cause danger.
(3) most of descending lifeline in use, the descending motion process is continuous, can not pause.Like this, easy of hiding when in the decline process, running into barrier not as good as causing personnel's unexpected injury.
(4) most of descending lifeline in use, the people that once can only descend, have only when a people descend finish after, just can use for another people, rescue efficiency is lower.
Summary of the invention
The purpose of this utility model provides a kind of rope descending lifeline of grabbing, and has solved the problem that the big use of existing descending lifeline volume is inconvenient, Parts Breakdown easily causes the Personal Risk, the decline process can't be paused and rescue efficiency is low.
The technical scheme that the utility model adopted is, a kind of rope descending lifeline of grabbing, comprise by pretension screw fixedly connected last hinge and lower jaw, the inside of last hinge and lower jaw is the half-cylindrical cavity that matches, have draw-in groove on the last hinge, the top of last hinge is provided with brake handle, brake handle by with last hinge on the fixture block that matches of draw-in groove size be stuck in the draw-in groove, the below of lower jaw is provided with safety belt.
Characteristics of the present utility model also are,
The inwall of last hinge wherein is provided with friction rubber sleeve a.
The inwall of lower jaw wherein is provided with friction rubber sleeve b.
The beneficial effects of the utility model are,
(1) small and exquisite, the very light in weight of descending lifeline structure can be used descending lifeline according to the installation site of life line temporarily, thereby effectively avoids the fire location of building lower floor.
(2) after life line is fixed, descending lifeline slides along life line.Because of nonmotile part in the descending lifeline, so can not hinder aloft for some reason by clamping stagnation.
Resistance when (3) it descends comes the frictional force between self-friction rubber sleeve and the life line.Available brake handle compresses rubber sleeve and realizes the regulation and control of frictional force therefore can realizing hovering of descending lifeline, to avoid the barrier on the descent path.
(4) because the structural similarity of this descending lifeline and hinge so be easy to it is connected with life line, can hang a plurality of rope descending lifelines of grabbing simultaneously on the life line, can improve rescue efficiency like this.
Description of drawings
Fig. 1 is the structural representation that the utility model is grabbed the rope descending lifeline;
Fig. 2 is that the utility model is grabbed the internal structure schematic diagram of going up hinge in the rope descending lifeline;
Fig. 3 is the internal structure schematic diagram that the utility model is grabbed lower jaw in the rope descending lifeline;
Fig. 4 is the structural representation that the utility model is grabbed brake handle in the rope descending lifeline.
Among the figure, 1. safety belt, 2. lower jaw is 3. gone up hinge, 4. pretension screw, 5. brake handle, 6. friction rubber sleeve a, 7. friction rubber sleeve b, 8. draw-in groove, 9. fixture block.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The utility model is grabbed the structure of rope descending lifeline, as shown in Figure 1, comprise by pretension screw 4 fixedly connected last hinge 3 and lower jaw 2, as shown in Figures 2 and 3, the inside of last hinge 3 and lower jaw 2 is the half-cylindrical cavity that matches, the inwall of last hinge 3 is provided with friction rubber sleeve a6, the inwall of lower jaw 2 is provided with friction rubber sleeve b7, have draw-in groove 8 on the last hinge 3, the top of last hinge 3 is provided with brake handle 5, the structure of brake handle 5 as shown in Figure 4, the below of brake handle 5 be provided with and last hinge 3 on the fixture block 9 that matches of draw-in groove 8 sizes, brake handle 5 is stuck in the draw-in groove 8 by fixture block 9, and the below of lower jaw 2 is provided with safety belt 1.
The course of work of the present utility model is: when needing escape, an end that with diameter is 10 millimeters life line earlier hangs in place, life line places in the internal cavities between hinge 3 and the lower jaw 2, regulate hinge 3 and lower jaw 2 in 4 fastenings of pretension screw, the drop-down descending lifeline of exerting oneself, the size of estimation frictional force, be adjusted to suitable frictional force, rescued personnel and utilize safety belt 1 that the health of oneself is connected with descending lifeline, descend with descending lifeline, in the decline process, with the pressure that brake handle 5 is regulated life line, depress brake handle 5, can increase friction rubber sleeve a6, frictional force between friction rubber sleeve b7 and the life line, thereby adjust friction rubber sleeve a6, frictional force between friction rubber sleeve b7 and the life line realizes the control gliding speed.
The utility model is grabbed the rope descending lifeline, and is simple in structure, in light weight, safe, and spendable crowd's scope is wide.Because it can open, close as hinge, therefore can on a life line, hang and a plurality ofly grab the rope descending lifeline, thereby improve lifesaving efficient widely.
