Abstract
The utility model discloses a flee and slowly fall ware, including shell, rope sheave, the machine of accelerateing, generator and load resistance, rope sheave, the machine of accelerateing, generator and load resistance all install the inside of fixing at the shell, the rope sheave is with the machine is continuous with higher speed, machine output is continuous with the generator with higher speed, dynamo output links to each other with load resistance. This flee and slowly fall ware simple structure does not use frictional resistance, and the safety and stability can not have frictional resistance, safety and stability according to the different slow deceleration degree of different weight adjustment moreover, the during operation, the rope sheave rotates, and through accelerateing machine drive generator, the generator rotated with higher rotational speed this moment, and the generator even has a load resistance, electricity consumption of sending the generator, just there was an electromagnetic damping effect in the rotation with regard to the generator this moment, adjustment load resistance's big I changes the size of electromagnetism resistance, thereby can come the different slow deceleration degree of adjustment according to different weight.
Description
Technical field
The utility model belongs to escape apparatus technical field, is specifically related to a kind of escaping descent control device.
Background technology
Escaping descent control device forms by linking up with (or suspension ring), suspender belt, rope and speeds control etc., be one can make people along (with) safe rescue equipment of the slow decline of rope (band).Its available dedicated mounted apparatus is arranged on the places such as building window, balcony or building flat, also can be arranged on elevating fire truck, succours the personnel that suffer a calamity or disaster be on the high-rise scene of a fire.Descending lifeline is applicable to high-rise escape, and the current escaping descent control device overwhelming majority drives the running of the reducing gear in main frame to produce rubbing action with the brake pad in friction wheel hub by the slow rope that falls, and ensures that the safety of user is slow and is down to ground.But descending lifeline of the prior art, most complex structure, volume are comparatively large, and cost is higher, and easily heating exists potential safety hazard, and quick and precisely cannot adjust decrease speed.
Utility model content
The purpose of this utility model is to provide a kind of escaping descent control device, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of escaping descent control device, comprise shell, rope sheave, acceleration machine, generator and load resistance, described rope sheave, acceleration machine, generator and load resistance are all fixed on the inside of shell, described rope sheave is connected with acceleration machine, described acceleration machine exports and is connected with generator, and described generator exports and is connected with load resistance.
Technique effect of the present utility model and advantage: when this escaping descent control device uses, shell and generator keep geo-stationary, and rope sheave is by drive electrical generators after acceleration machine; Now, the rotating speed of generator is the multiple of rope sheave rotating speed, and this multiple depends on the acceleration multiple of acceleration machine; The output of generator is connected with load resistance; During work, rope sheave rotates, and by accelerating machine drive electrical generators, now generator rotates with higher rotation speed; And generator is connected with load resistance, the electricity that generator sends is consumed; Just there is an electromagnetic damping effect in the rotation now with regard to generator; The large I of adjustment load resistance changes the size of electromagnetic resistance; Thus different slow reduction of speed degree can be adjusted according to different weight; This slow descending device structure is simple, does not use frictional resistance, safety and stability, and can adjust different slow reduction of speed degree without frictional resistance according to different weight, safety and stability.
Accompanying drawing explanation
Fig. 1 is the utility model block diagram representation;
Fig. 2 is the utility model structural representation.
In figure: 1 rope sheave, 2 accelerates machine, 3 generators, 4 load resistances, 5 shells.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of escaping descent control device as shown in Figure 1, comprise shell 5, rope sheave 1, acceleration machine 2, generator 3 and load resistance 4, described rope sheave 1, acceleration machine 2, generator 3 and load resistance 4 are all fixed on the inside of shell 5, described rope sheave 1 is connected with acceleration machine 2, described acceleration machine 2 exports and is connected with generator 3, and described generator 3 exports and is connected with load resistance 4.
Operation principle: as shown in Figure 2, during work, rotation due to rope sheave 1 drives the high-speed rotation of acceleration machine 2, so just export a higher rotation speed at the output of acceleration machine 2, and this higher rotating speed supply generator 3 makes it rotate generating, the electricity that generator 3 sends is access to load resistance 4, because generator 3 is added with load, so the effect of electromagnetic damping power will be subject in rotation process, this power feeds back to acceleration machine 3 gear train by axle thus plays the effect suppressing rope sheave 1 decrease speed, and electromagnetic damping realizes easily via regulating load resistance.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to previous embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
