Abstract
The utility model discloses a high-rise slow descending device, which comprises a roller rack, a roller arranged on the roller rack, and a steel wire rope wound on the roller, wherein a roller spindle of the roller is divided into lead screws in the roller rack; the left ends of the lead screws are provided with fixing rings being vertical to the lead screws; moving rings are also screwed on the lead screws; the lead screws are sheathed with compression springs; the compression springs are arranged between the fixing rings and the moving rings; a roller sleeve of the roller is sheathed on the fixing rings and the moving rings; the roller sleeve and the fixing rings are positioned in the axial direction and are in sliding fit in the circumferential direction; and the roller sleeve and the moving rings are in sliding key fit. Compared with the prior art, the utility model has the advantages of simple structure, low price and energy saving and is safe and practical, and power is not needed.
Description
Technical field
The utility model relates to a kind of slowly descending device for high building.
Background technology
Present slow descending device is the power slow descending device, promptly is the electronic slow descending device of one by motor, planet-gear speed reducer and cylinder.The shortcoming of this device is: the first, and complex structure costs an arm and a leg; The second, do not having under the situation of electric power, device can not turn round, and particularly catches fire after electric device burnt out at high building, and when people need use the slow descending device escape, the shortcoming of this device was just more outstanding.Therefore, designing a kind of slow descending device without electric power, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of slow descending device without electric power.
The technical scheme in the invention for solving the technical problem is:
Slowly descending device for high building, form by roller shelves and the steel wire rope that is installed in the cylinder on the roller shelves and be wrapped on the cylinder, the drum shaft of this cylinder is divided into leading screw in roller shelves inside, left end at leading screw is provided with the retainer ring vertical with leading screw, on leading screw, also be installed with loose collar, on leading screw, be set with the compression spring, the compression spring is between retainer ring and loose collar, the jacket casing of this cylinder is sleeved on retainer ring and the loose collar, axial location circumferentially is slidingly matched between jacket casing and the retainer ring, and feather key cooperates between jacket casing and the loose collar.
The technical scheme in the invention for solving the technical problem can also be:
Roller shelves described in the utility model is made of left supported plate, right supported plate, last fulcrum and following fulcrum, the threaded connecting rod in thick two in the middle of last fulcrum and following fulcrum are, both ends at left supported plate and right supported plate are provided with connecting hole, roller shelves is formed by connecting by nut by left supported plate, right supported plate, last fulcrum and following fulcrum, the mid portion of described drum shaft is thicker, its two is thinner and threaded, be provided with the drum shaft installing hole at the middle part of left supported plate and right supported plate, drum shaft is fixed between left supported plate and the right supported plate by nut.
Axial location circumferentially is slidingly matched and cooperates for annular groove and ring are protruding or the annular groove ball cooperates between jacket casing of the present utility model and the retainer ring.
Feather key cooperates for jacket casing convex feather key and cooperates with the loose collar chute or loose collar evagination feather key cooperates with the jacket casing chute between jacket casing of the present utility model and the loose collar.
Operation principle of the present utility model: when the people catches steel wire rope to fall downwards, steel wire rope drives the cylinder rotation, cylinder drives the loose collar rotation, loose collar is extruding compression spring in rotation, compression spring and loose collar produce frictional force, to reduce the rotary speed of loose collar and cylinder, reach the slow purpose that descends of people.
Compared with prior art, the utlity model has simple in structure, cheap, do not need power, energy savings, safe and practical advantage.
