Abstract
The utility model relates to a kind of lifesaving descent control device, it comprises: upper shell, lower house, rope-winding wheel, gear, gear shaft, blade, arrestment mechanism, rolling bearing, wherein Friction speed-reducing device adopts and organizes arrestment mechanism more, when falling head is constant, the heat energy changed by gravitational potential the subject of knowledge and the object of knowledge is constant, adopt and organize arrestment mechanism more, increase friction area and area of dissipation, reduce the wearing and tearing of single friction mechanism simultaneously, the security of lifesaving descent control device and service life are increased greatly, many groups arrestment mechanism runs simultaneously, stress balance, during the rapid wear of side, opposite side carries out friciton compensation and makes the speed of service of equipment steady, the discrepancy rope mouth of housing is provided with rolling bearing, safety rope and the mouth of restricting of coming in and going out are connected for rolling, avoid card rope phenomenon.
Description
Technical field
The utility model relates to a kind of lifesaving descent control device.
Background technology
Lifesaving descent control device is a kind of survival equipment being widely used in high altitude escape, the main heating source of lifesaving descent control device is from the friction of arrestment mechanism, brakes friction disc wear is too fast in use for legacy equipment, the Reusability life-span is short, rope mouth of coming in and going out easily blocks the drawback of rope, and only has single brakes, and when equipment runs, all heats concentrate on a place and can cause localized hyperthermia, the parts of infringement equipment, reduce mechanical performance and threaten the personal safety of user.
Summary of the invention
Problem to be solved in the utility model is, friction disc wear when overcoming equipment Reusability in prior art in arrestment mechanism is fast, the problem that service life is short, in customer service prior art, centrifugal friction mechanism is positioned at one-sided, run jiggly problem, dispel the heat in equipment use process in solution prior art insufficient, the problem that temperature is too high, in solution prior art, safety rope is in the problem of rope mouth clamping stagnation of coming in and going out.
The technical solution adopted in the utility model is, adopt many arrestment mechanisms, stress balance when multiple arrestment mechanism runs, the load produced when operating personnel declines on average is shared by multiple arrestment mechanism, reduce the frictional force of single mechanism, if side friction plate rapid wear in use, opposite side friction plate can play compensating action, during running, more traditional single shoe brake is more steady, the friction plate in arrestment mechanism is made to have the longer life-span, the design of many arrestment mechanisms has simultaneously disperseed thermal source, on, lower house has louvre, equipment heat is in use more effective to shed thus protects equipment, discrepancy rope mouth place increases rolling bearing, avoid the clamping stagnation problem of safety rope when passing in and out lifesaving descent control device.

Fig. 1 is the overall appearance figure of the utility model embodiment;
Fig. 2 is the cut-away view of the utility model embodiment;
Fig. 3 is the brake composition of the utility model embodiment; Wherein: 1, upper shell; 2, blade; 3, arrestment mechanism; 4, lower house; 5, gear shaft; 6, gear; 7, rope-winding wheel; 8, rolling bearing; 3-1, locating piece; 3-2, spring; 3-3, friction plate; 3-4, friction plate fixed block.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, be overall appearance design form of the present utility model;
As Fig. 2, shown in Fig. 3, rope-winding wheel 7 and gear 6 are fixed by straight pin, then enclosure interior is installed to, arrestment mechanism 3 is by locating piece 3-1, spring 3-2, friction plate 3-3 and friction plate fixed block 3-4 forms, friction plate 3-3 is bonding with friction plate fixed block 3-4, by spring 3-2, friction plate fixed block 3-4 and locating piece 3-1 is linked together, locating piece 3-1 and gear shaft 5 are fixed by straight pin, blade 2 is installed to outside locating piece 3-1 by screw, correspondence is installed in housing, during work, rope-winding wheel 7 rotates, the gear 6 driven gear axle 5 be fixed together with rope-winding wheel 7 and rotating together with being installed on gear shaft 5 locating piece 3-1, the blade 2 be now fixedly connected with locating piece 3-1 produces and rotates, drive upper shell 1, air flowing in lower house 4, by upper shell 1, the louvre of lower house 4, the heat that air-flow produces when taking away equipment use, owing to have employed the design of many arrestment mechanisms, during equipment use, one-sided generation frictional force reduces, caloric value reduces, because this reducing the wearing and tearing of friction plate, add the life cycle of friction plate 3-3, simultaneously due to the design of multiple brakes, disperse thermal source and both sides all have blade 2, thus the heat that the equipment that ensure that produces distributes more rapidly and makes equipment keep a relatively low operating temperature, ensure that the service behaviour of lifesaving descent control device.Rolling bearing 8 is installed on the discrepancy rope mouth place of upper-lower casing, and be connected for rolling with rolling bearing 8 during safety rope access device, resistance is less than being slidably connected of legacy equipment, avoids the appearance of card rope phenomenon, has ensured the safety that operating personnel declines when escaping.
It is only preferred embodiment of the present utility model above; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
