Description
Technical field
The invention belongs to tower machine equipment field for building, relates to tower machine accessory, and specifically safety device climbed by a kind of multiple brake type tower machine.
Background technology
Existing skyscraper tower machine, tower machine work, in the process of upper and lower tower machine, generally adopts free-hand climbing tower ladder, without the mode of safety precaution, because tower machine raises along with increasing of building, up to more than ten layers, in climbing, by environment and self etc. affect, speed of not only climbing is slow, and there are major safety risks, when once accidentally drop or slip, fatal accident can be caused to occur.
Summary of the invention
The object of the invention is to provide a kind of multiple brake type tower machine to climb safety device, with multiple brake measure, can guarantee the safety of tower machine work in upper and lower tower machine process, improve climbing speed, avoid labor safety accident.
The technical scheme that the invention is taked is that safety device climbed by a kind of multiple brake type tower machine of design, its structure comprises: safety strap, safety rope, safety rope is connected with drawing rope one end, the solid suspension member with tower ladder is provided with in this one end of drawing rope, the rope body of drawing rope coils mutually with the front and back fixed pulley of the assembly pulley be laid on tower ladder in squarer machine frame and middle movable pulley respectively and is connected, clump weight is connected with at the other end of drawing rope, wherein, a fixed pulley in office is provided with described centrifugal accident brake, movable pulley is provided with described gravity type boat davit speed lock drg, on the wheel rim of the rear fixed pulley of described assembly pulley, correspondingly with the ratchet on middle movable pulley flange be provided with ratchet, combine the front and back fixed pulley to assembly pulley and the multiple reinforcement braking of movable pulley.
In such scheme, described centrifugal accident brake is laid on the front fixed pulley of assembly pulley and the side wheel face of rear fixed pulley.
Described centrifugal accident brake is laid on the both sides wheel face of rear fixed pulley.
In said structure, described centrifugal accident brake adopts on fixed pulley wheel face, is provided with more than one centrifugal hook, and the body of rod of centrifugal hook is provided with extension spring, and the body of rod is located in rail groove, and on fixed housing, the hook end of corresponding centrifugal hook is provided with positive stop.When in climbing tower machine process, accidentally drop or slip, out of control falling occurs, and fixed pulley plays deceleration effort, and when the quick despining of fixed pulley, the centrifugal hook on wheel face can auto-extending thereupon, blocks the positive stop on fixed housing, plays emergency braking effect to fixed pulley.
Described gravity type boat davit speed lock drg, adopt and be provided with ratchet on the wheel rim of the movable pulley of assembly pulley, the bottom, bearing frame two ends of movable pulley is provided with U-shaped pulling-on piece, Compress Spring is provided with in U-shaped pulling-on piece, or extension spring is provided with under U-shaped pulling-on piece and between shell, above movable pulley, corresponding ratchet is fixed with slipper.When in climbing tower machine process, there is out of control falling, movable pulley reverses, safety rope (drawing rope) pulling force increases, be greater than the application force of spring to movable pulley, break the critical conditions on movable pulley residing for ratchet, the slipper of movable pulley upward movement and top is inconsistent, reaches movable pulley speed lock brake action.
On the wheel rim of rear fixed pulley, correspondingly with the ratchet on movable pulley flange be provided with ratchet, combine, when in climbing, out of control falling occurs with above-mentioned brake measure, rear fixed pulley, under the effect of centrifugal accident brake, produces braking; Movable pulley, under the effect of gravity type boat davit speed lock drg, also produces braking; Ratchet while movable pulley produces self braking on movable pulley, can fasten with the ratchet on rear fixed pulley wheel rim again, brakes with the related generation of rear fixed pulley producing braking.
Safety device climbed by this multiple brake type tower machine of the invention, owing to adopting technique scheme and measure, the Emergency time fallen out of control can be climbed in tower machine work, by the centrifugal accident brake be located on the fixed pulley of front and back and the gravity type boat davit speed lock drg be located on movable pulley, and movable pulley flange ratchet coordinates the many kinds of measures such as related with rear fixed pulley wheel rim ratchet, there is multiple reinforcement braking, more effectively guarantee that tower machine work climbs safety, avoid labor safety accident to occur, the remarkable advantage of climbing tower motor speed can be improved again.
