Abstract
The utility model discloses a rotary-type braking device which comprises a shell body, a drag cone and a check ring, wherein the drag cone is connected with the shell body in a rotating mode, outer threads are arranged in an end portion of the drag cone; the check ring axially fixes the shell body; a threaded hole is formed in the check ring; an end portion of the drag cone is immediately close to / extends into the threaded hole; inner threads of the threaded hole are matched with the outer threads; and a brake pad which fixes the shell body is arranged in the moving trend direction of the drag cone. The rotary-type braking device can conduct braking on a rotating bearing.
Description
Technical field
The utility model relates to a kind of rotary type braking device.
Background technique
In the prior art, with the equipment of certain speed operation if mechanical failure, can be quite dangerous, be example with the hanging basket in building-site construction, hanging basket is in transportation article or personnel, if elevating system breaks down, cause hanging basket to accelerate tenesmus, and because the elevating system of hanging basket all has relation with the rotation of axle, how to realize the rotary type braking, be a problem demanding prompt solution.
The model utility content
At the problem that prior art exists, the purpose of this utility model is to propose a kind of rotary type braking device, and this device can be implemented braking to the bearing of rotation.
For reaching this purpose, the utility model by the following technical solutions:
Propose a kind of rotary type braking device, comprise housing; The be rotationally connected drag cone of housing, the end of drag cone is provided with outside thread; The back-up ring of axial restraint housing is established screw in the back-up ring, the drag cone end is close to/stretches into screw, and the internal thread of screw cooperates with outside thread; Be provided with the brake block of stationary housing in the movement tendency direction of drag cone.Be provided with first protuberance in the outside of drag cone, be provided with second protuberance in the outside of back-up ring, between first protuberance and second protuberance, be provided with damping device.Between damping device and first protuberance or second protuberance, be provided with block.Damping device is dish spring group.
Based on disclosing of above technological scheme, the utility model possesses following beneficial effect:
In the utility model, when drag cone rotates, its end will be absorbed in the screw, make drag cone move axially, and drag cone touches brake block, thereby drag cone is stopped operating, and in like manner, the rotating shaft that drives drag cone be stopped operating.
Description of drawings
Fig. 1 is the utility model embodiment 1 overall structure schematic representation:
Wherein: 1, housing; 2, drag cone; 21, end; 3, brake block; 4, damping device; 5, back-up ring; 6, block.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment:
Embodiment 1
Propose a kind of rotary type braking device, comprise housing 1; The be rotationally connected drag cone 2 of housing 1, the end 21 of drag cone 2 is provided with outside thread; The back-up ring 5 of axial restraint housing 1 is established screw in the back-up ring 5, and drag cone 2 ends 21 are close to/stretch into screw, and the internal thread of screw cooperates with outside thread; Be provided with the brake block 3 of stationary housing 1 in the movement tendency direction of drag cone 2.Be provided with first protuberance in the outside of drag cone 2, be provided with second protuberance in the outside of back-up ring 5, between first protuberance and second protuberance, be provided with damping device 4.Between damping device 4 and first protuberance or second protuberance, be provided with block 6.Damping device 4 is dish spring group.
When drag cone 2 rotates, its end 21 will be absorbed in the screw, make drag cone 2 move axially, and drag cone 2 touches brake block 3, and drag cone 2 is stopped operating, and in like manner, the rotating shaft that drives drag cone 2 be stopped operating.
The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and model utility design thereof, all should be encompassed within the protection domain of the present utility model.
