Description
Technical field
The utility model belongs to parking equipment technical field, is specifically related to a kind of cylindrical drum hoist rope-loosing protection device.
Background technology
Growing along with parking apparatus, the application of cylindrical drum hoist is more and more extensive, cylindrical drum hoist below when skip bucket, easily occur card skip bucket phenomenon, and steel rope continues to send rope, once the free double action of skip bucket, under acceleration due to gravity, can damage steel rope, even there is earning the phenomenon of disconnected steel rope, there is falling accident, abnormally dangerous.
Summary of the invention
For the deficiencies in the prior art; the purpose of this utility model is to provide a kind of cylindrical drum hoist rope-loosing protection device; solve after elevator-cup blocks and continue to send rope fault; can stop in time; prevent because of haulage cable slack rope longly, skip bucket recovers the phenomenon that when motion earns disconnected steel rope, sensitive quick; simple in structure, convenient and practical.
Cylindrical drum hoist rope-loosing protection device described in the utility model, comprise base, base top is fixedly installed bracing frame, bracing frame top is fixedly installed lift cylinder, lift cylinder top is fixedly installed rotating machine, rotating machine top is fixedly installed S. A., S. A. top is fixedly connected with one end of crossbeam, the other end of crossbeam connects the axis of reel, reel is provided with steel wire rope groove, steel rope is by drawing in steel wire rope groove, steel rope one end is fixedly connected with skip bucket, crossbeam bottom between S. A. and reel arranges micro-switch rack, micro-switch rack bottom arranges micro-switch, the close hinged portable plate of micro-switch one side on reel, hinge-point equates with the vertical length of micro-switch rack to the vertical distance of crossbeam, the length of portable plate is greater than the distance of hinge-point to micro-switch, portable plate is connected with reel by spring, spring and micro-switch are positioned at the same side of portable plate.
When use, base top is fixedly installed bracing frame, and bracing frame top is fixedly installed lift cylinder, and lift cylinder can driven rotary motor, S. A. and crossbeam move up and down, thereby realizes the adjustment of differing heights; Owing to being fixedly installed rotating machine on lift cylinder top, rotating machine top is fixedly installed S. A., and S. A. top is fixedly connected with one end of crossbeam, and S. A. rotates under the drive of rotating machine, drive again crossbeam-rotating, thereby band movable reel and skip bucket are realized circular movement.Reel is provided with steel wire rope groove, and steel rope is by drawing in steel wire rope groove, and steel rope one end is fixedly connected with skip bucket, and skip bucket moves up and down under the traction of steel rope.The close hinged portable plate of micro-switch one side on reel, hinge-point equates with the vertical length of micro-switch rack to the vertical distance of crossbeam, the length of portable plate is greater than the distance of hinge-point to micro-switch, portable plate is connected with reel by spring, and spring and micro-switch are positioned at the same side of portable plate.In the time moving up and down under the traction of skip bucket at steel rope, one end of portable plate is hinged on reel, and the other end of portable plate is pulled open and is against on steel rope downwards.In the time that skip bucket blocks, looseness of steel wire ropes, portable plate rotates around hinge-point under the effect of spring, and because the length of portable plate is greater than the distance of hinge-point to micro-switch, portable plate one end impinges upon on micro-switch, makes equipment out of service immediately.
In sum, the utlity model has following advantage:
(1) the utility model has solved after elevator-cup blocks and has continued to send rope fault, can stop in time, has prevented because of haulage cable slack rope longly, and skip bucket recovers the phenomenon that when motion earns the steel rope that breaks.
(2) the utility model is sensitive fast, simple in structure, practical.
(3) the utility model is easy to use, can make as required skip bucket do lifting or circular movement, convenient and practical.
