The utility model comprises a rope disk, a steel rope, a gear accelerator, a main shaft, a casing body and a friction device, wherein the main shaft is arranged on the casing body in a rotary way and the rope disk is sheathed on the main shaft. The friction device comprises a flying disk, a centrifugal weight block and a friction component, wherein the centrifugal weight block is radially and movably arranged in an outer edge groove of the flying disk and the friction component is fixedly arranged on the centrifugal weight block. The rope disk is connected with the main shaft and the flying disk in a transmission way by the gear accelerator. The utility model has the advantages that the rope disk and the friction device are arranged in the casing body, and the rope disk is connected with the gear accelerator in a transmission way; thus, the utility model has the advantage of simple and compact structure; in addition, the flying disk in the friction device is connected with the main shaft by an overrunning clutch in a one-way transmission way, and a crank handle is arranged on the main shaft, so that friction force can not be produced in the process of lifting; thus, the crank handle and the gear accelerator has speed-down effect, so that the utility model can lift person and objects in a labor saving way; the utility model has the characteristic of one machine with multifunction.
Description
Technical field:
The utility model relates to and a kind ofly falls the people or rise the device of human from building or analog, relates in particular to the escape apparatus that a kind of use has the rope falling unit of brake.
Background technology:
At present in fire-fighting, the employed slow equipment that falls in the relief, a kind of is to drive decelerator by external impetus to realize the slow purpose of falling, its weak point is bulky, complex structure, need external impetus, consumes energy, another kind is the prior art comparatively approaching with the utility model, mainly be to utilize gear to quicken to rotate, the work of drive friction device, thereby reach slow purpose of falling, for example: the patent No. is 200420011707.4, Granted publication day is on April 6th, 2005, name is called the Chinese utility model patent of " unpowered friction deceleration device ", it is to reach the speed increasing mechanism that is provided with by main shaft on main shaft, fly frame, steel ball, platen, slip ring, the paw connecting rod, paw, paw frame and friction mechanism constitute, and its shortcoming is that structure is comparatively complicated.
Summary of the invention:
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, the escape apparatus that provides a kind of simple in structure, compact having to restrict falling unit.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: escape apparatus, comprise cheese, steel wire rope, gear accelerator, main shaft, housing and friction device, described main shaft places on the housing rotationally, cheese is set on the main shaft, friction device comprises flying disc, centrifugal weight and friction part, described centrifugal weight radially places the border groove of flying disc versatilely, and the friction part is installed on the centrifugal weight, and cheese is in transmission connection by gear accelerator and main shaft and flying disc.
The beneficial effects of the utility model are: because cheese and friction device place housing, and be in transmission connection by the gear accelerator, thereby have simple in structure, compact advantage, in addition, the flying disc in the friction device is by freewheel clutch and main shaft is unidirectional is in transmission connection, and on main shaft, be provided with crank handle, when rising, do not produce friction, thereby can be by crank handle and gear accelerator (playing decelerating effect this moment), promote personnel and object comparatively effortlessly, have the advantage of a tractor serves several purposes.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is described further.
As shown in the figure, 1 is the fire prevention wear-resisting steel wire rope of circle on steel wire disk, 2 is cheese, and 3 is the planetary gear accelerator, and 4 is main shaft, 5 for being fixed on the freewheel clutch on the main shaft, 6 for being fixed on flying disc on the freewheel clutch shell, and 7 for being movably arranged on the centrifugal weight on the flying disc, and 8 are the friction part on being fixedly mounted on outside the centrifugal weight, 9 is shell, and 10 for being equipped with the crank handle of clutch structure.Escape apparatus, comprise cheese 2, steel wire rope 1, gear accelerator 3, main shaft 4, housing 9 and friction device, described main shaft 4 places on the housing 9 rotationally, cheese 2 is set on the main shaft 4, friction device comprises flying disc 6, centrifugal weight 7 and friction part 8, described centrifugal weight 7 radially places the border groove of flying disc 6 versatilely, and friction part 8 is installed on the centrifugal weight 7, and cheese 2 is in transmission connection with flying disc 6 by gear accelerator 3 and main shaft 4.Be provided with freewheel clutch 5 between described flying disc 6 and the main shaft 4, constitute unidirectional being in transmission connection.Described gear accelerator 3 comprises centre wheel 11, planetary gear 12 and sun gear 13, cheese 2 skies are enclosed within on the main shaft 4, and fixedly connected with sun gear 13, and centre wheel 13 is fixedlyed connected with main shaft 4, planetary gear 12 and centre wheel 11 and sun gear 13 engagements, the pivoted arm of planetary gear 12 is fixedlyed connected with housing 9.Described main shaft 4 stretches out on housing 9 end outward and is installed with crank handle 10.Also be provided with compression spring 14 between described flying disc 6 and the centrifugal weight 7.
The utility model can be installed arbitrarily or be bundled in solid place with rope band.During use, along with being buckled in escape personnel's pulling out of steel wire rope 1 on one's body, drive the cheese 2 that planetary gear accelerator 3 is housed on one side, thereby make main shaft 4 quick rotation, the heart of freewheel clutch 5 is fixed on again on the main shaft 4, freewheel clutch 5 is rotated apace, flying disc 6 is fixedly mounted on the shell of freewheel clutch 5, freewheel clutch 5 closes and drives flying disc 6 quick rotation, centrifugal weight 7 was installed on the flying disc 6 again versatilely when flying disc 6 rotated, the centrifugal force that centrifugal weight 7 produces is pressed on the inboard of shell 9 friction part 8 on the centrifugal weight 7 and rubs, thereby plays the friction decelerating effect.Friction part 8 also can be made annulus, is fixed on the housing.
The withdrawal of steel wire rope, backward rotation crank handle 10, drive the rotation of main shaft 4, through planetary gear speed-reduction, because flying disc 6 is mounted on the shell of freewheel clutch 5, freewheel clutch 5 leaves during backward rotation crank handle 10, thereby rotate very light, weight also can pull even steel wire rope is being hung oneself, and this device also can be used for lifesaving, and is reusable.
This device does not use motor and electric equipment products, so, under the situation that does not have electricity, can both use safely and reliably; This device can also be carried to the people and the mountaineer of eminence work, serves as the instrument of safeguard protection, escape and lifesaving where necessary.
