Description
Technical field
The present invention relates to a kind of brake equipment of fly rope, relate in particular to a kind of elevator rope rotation brake device.
Background technology
The common end of hoist ropes is fixed on the elevator counterweight, and the other end is fixed in car, realizes the up-down of elevator through forward and reverse rotation of traction sheave.The multi-rope friction hoisting form is a kind of form that adopts usually, and it is big to have hoisting capacity, the advantage that degree of safety is high.The direct braking object of at present common drg is divided into two kinds of cage guide and hoist ropes.Brake structural to guide rail is complicated, and cost is higher.And the usually used drg to hoist ropes adopts the form of two parallel plates folder rope braking, and required gripping power is big, is easy to generate looseningly, influences safety.
Summary of the invention
The present invention has overcome the deficiency of prior art, provides a kind of simple in structure, and gripping power is big, braking is stable, prevents that hoist ropes from skidding off, and resetting conveniently has the brake for towline of elevator of buffering.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of brake for towline of elevator, said hoist ropes are more than two or two, and press straight-though arrangement; It is characterized in that: comprise the rope gripper that rotates around anchor shaft and stop the dynamic resistance device of locating said rope gripper; Said rope gripper comprises two rope clamping blocks of integral type, and said anchor shaft is located in the rope clamping block, and two rope clamping blocks keep at a certain distance away and establish relatively; The middle strip crack that forms; Said crack is little perpendicular to the big centre, two, cross section of anchor shaft, and middle minimum place width is the diameter of a hoist ropes, and said dynamic resistance device comprises the block that is fixed on the rope gripper rotation direction.
In preferred embodiment of the present invention, comprise that further said anchor shaft is provided with retracing spring.
In preferred embodiment of the present invention, comprise that further said block is the magnetic block, is provided with the electromagnet with said block magnetic attraction in the rope gripper.
In preferred embodiment of the present invention, comprise that further said rope gripper is provided with the electromagnet catch that shape matches with the group block face of said block.
In preferred embodiment of the present invention, further comprise on the said rope clamping block, respectively be provided with a catch, also coorespondingly in the said dynamic resistance device be provided with two blocks along fixing axial both sides.
In preferred embodiment of the present invention, the opposite face that further comprises said two rope clamping blocks is the evagination arcwall face.
In preferred embodiment of the present invention, comprise that further said two rope clamping blocks link to each other through connecting strap is corresponding respectively along two of said crack direction, said along the crack direction every is being provided with a connecting piece along fixing axial two ends.
In preferred embodiment of the present invention, comprise that further vertical distance between the connecting strap at fixing axial two ends, said rope clamping block upper edge is greater than the width of said row's hoist ropes.
The invention solves the defective that exists in the background technology, brake for towline of elevator gripping power of the present invention is big, and good braking effect and braking are stable, and is little to hoist ropes and drg injury, resets not have and blocks.The form that can adopt electromagnet and magnetic catch to cooperate drives and stops rope gripper, cooperates retracing spring, realizes motorized control, and braking is stable, need not hand reset or other complicated reset mode, and is convenient.Hoist ropes at longitudinal extension is provided with the electromagnet catch respectively along fixing axial both sides and to the magnetropism block, reserves hoist ropes fall line space, stops the hoist ropes motion when preventing normal operation.

The specific embodiment
Combine accompanying drawing and embodiment that the present invention is done further detailed explanation now, these accompanying drawings are the scheme drawing of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Shown in Fig. 1-3; A kind of brake for towline of elevator of the present invention, wherein hoist ropes 1 is 3, diameter is identical; And the straight-though arrangement of pressing parallel to each other, said drg comprise around the rope gripper of anchor shaft 21 rotations and stop the dynamic resistance device of locating said rope gripper.Said rope gripper comprises two rope clamping blocks of integral type, i.e. rope clamping block 2, rope clamping block 4.Said anchor shaft 21 is located in the rope clamping block 2, and anchor shaft 21 is provided with retracing spring.Two rope clamping blocks keep at a certain distance away and establish relatively; Opposite face is the evagination arcwall face, the middle strip crack 6 that forms, and said crack 6 is perpendicular to the sectional axis symmetry of anchor shaft 21; And big centre, two is little, and middle minimum place width is the diameter of a hoist ropes 1.Said rope clamping block 4 is with respect to the exterior bottom of rope clamping block 2, respectively is provided with an electromagnet catch 41 along the both sides of anchor shaft 21 directions.Said dynamic resistance device comprises wedge shape back-up block 10 and is located at two blocks 8 on back-up block 10 inclined-planes; Two blocks 8 are corresponding with said two catch 41 along the position of anchor shaft 21 directions; Block 8 comprises the magnetic wedge shape stop part 81 of being located at its top, corresponding respectively the matching of group block face 811 of the shape of said two catch 41, size and two stop parts 81.Respectively through 12 corresponding linking to each other of connecting strap, said along crack 6 directions every is provided with a connecting piece 12 at the two ends along anchor shaft 21 directions to two rope clamping blocks along two of said crack 6 directions.The lateral surface correspondence perpendicular to anchor shaft 21 of two rope clamping blocks flushes, and the vertical distance that the connecting strap at the two ends of rope clamping block upper edge anchor shaft 21 directions is 12 is greater than the width of said row's hoist ropes 1.Vertically hollow out the convenient hoist ropes 1 of settling on the said wedge shape back-up block 10 between two stoppers 8.
During installation; The hoist ropes 1 of 3 longitudinal extensions of one row is passed the crack 6 of drg rope gripper, and hoist ropes 1 bearing of trend is parallel to crack 6 axis of symmetry axis, and retaining means is set; Stop part 81 is positioned on the circumferential turned position of catch 41; Two stop parts 81 and two catch 41 are corresponding respectively along the axial positions of anchor shaft 21, and the blocking surface 811 of stop part 81 is relative with corresponding catch 41, and catch 41 bottom height are lower than corresponding stop part 81 top height.One row's hoist ropes 1 passes between two stoppers 8, and cut-out on the back-up block 10, during the normal operation traction, can not receive the influence of retaining means.Through electromagnet catch 41 attraction with magnetic stop part 81, drive the rope gripper rotation in case of necessity, the cross travel of crack 6 width gradually, slyness diminishes, and clamps hoist ropes 1, and catch 41 is static by stop part 81 brakings; Outage removes electromagnetic force, and rope gripper restores the beginning position next time in the effect of retracing spring, and retracing spring has also played buffer action simultaneously, the protection rope gripper.Connecting strap 12 on two rope clamping blocks not only plays interconnect function, can also prevent that hoist ropes 1 from skidding off drg along anchor shaft 21 directions simultaneously, and safer, braking effect is better.
Above foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification sheets, must confirm technical scope according to the claim scope.
