The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the scheme drawing of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Figure 1-3, a kind of brake for towline of elevator of the present utility model, wherein hoist ropes 1 is 3, diameter is identical, and the straight-though arrangement of pressing parallel to each other, described drg comprise around the rope gripper of anchor shaft 21 rotations and stop the dynamic resistance device of locating described rope gripper.Described rope gripper comprises two rope clamping blocks of integral type, i.e. rope clamping block 2, rope clamping block 4.Described 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 relatively establish, opposite face is the evagination arcwall face, the middle strip crack 6 that forms, and described crack 6 is symmetrical perpendicular to the sectional axis of anchor shaft 21, and large centre, two is little, and middle minimum place width is the diameter of a hoist ropes 1.Described 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.Described dynamic resistance device comprises wedge shape back-up block 10 and two blocks 8 being located on back-up block 10 inclined-planes, two blocks 8 are corresponding with described two catch 41 along the position of anchor shaft 21 directions, block 8 comprises the magnetic wedge form drag stopper 81 of being located at its top, and the group block face 811 of the shape of described two catch 41, size and two stop parts 81 is corresponding matching respectively.Respectively by 12 corresponding linking to each other of connecting strap, described 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 described crack 6 directions.The lateral surface correspondence perpendicular to anchor shaft 21 of two rope clamping blocks flushes, on the rope clamping block along the vertical distance of 12 of the connecting straps at the two ends of the anchor shaft 21 directions width greater than described row's hoist ropes 1.Vertically hollow out the convenient hoist ropes 1 of settling on the described 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, hoist ropes 1 bearing of trend is parallel to crack 6 axis of symmetry axis, 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 position 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 be subject to the impact of retaining means.By 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, round and smooth diminishing, clamp hoist ropes 1, it is static that catch 41 is blocked section's 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, the protective folder rope device simultaneously.Connecting strap 12 on two rope clamping blocks not only plays connection 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 utility model is enlightenment, and by above-mentioned description, the related personnel can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification sheets, must determine technical scope according to the claim scope.
