For achieving the above object, the technical solution used in the present invention is: a kind of brake for towline of elevator, described hoist ropes is more than two or two, and press straight-though arrangement, it is characterized in that: comprise the rope gripper rotated around anchor shaft and the dynamic resistance device stopping the described rope gripper in location, described rope gripper comprises two rope clamping blocks of integral type, described anchor shaft is located in a rope clamping block, two rope clamping blocks keep at a certain distance away relatively and establish, middle formation one strip crack, described crack is little perpendicular to the large centre, two, cross section of anchor shaft, middle minimum place width is the diameter of a hoist ropes, described dynamic resistance device comprises the stopper be fixed in rope gripper rotation direction.
In a preferred embodiment of the present invention, comprise described anchor shaft further and be provided with retracing spring.
In a preferred embodiment of the present invention, comprising described stopper is further magnetic stop block, is provided with the electromagnet with described stopper magnetic attraction in rope gripper.
In a preferred embodiment of the present invention, comprise described rope gripper further and be provided with the electromagnet catch that shape matches with the blocking surface of described stopper.
In a preferred embodiment of the present invention, comprise on a described rope clamping block further, be respectively provided with an electromagnet catch along fixing axial both sides, also correspondingly in described dynamic resistance device be provided with two stoppers.
In a preferred embodiment of the present invention, the opposite face comprising described two rope clamping blocks is further evagination arcwall face.
In a preferred embodiment of the present invention, comprise described two rope clamping blocks further and be connected respectively by connecting strap correspondence along the two in described crack direction, be describedly provided with a connecting piece along every of crack direction along fixing axial two ends.
In a preferred embodiment of the present invention, comprise the width described rope clamping block being greater than described row's hoist ropes along the vertical distance between the connecting strap at fixing axial two ends further.
The invention solves the defect existed in background technology, brake for towline of elevator gripping power of the present invention is large, good braking effect and braking is stable, to hoist ropes and drg injury little, reset unobstructed.The form that electromagnet and magnetic catch can be adopted to coordinate drives and stops rope gripper, coordinates retracing spring, and realize motorized and control, braking is stable, without the need to hand reset or other complicated reset mode, convenient.At the hoist ropes of longitudinal extension, electromagnet catch and corresponding magnetic stop block are set respectively along fixing axial both sides, reserve hoist ropes fall line space, when preventing from normally working, stop hoist ropes motion.

Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Figure 1-3, a kind of brake for towline of elevator of the present invention, wherein hoist ropes 1 is 3, and diameter is identical, and parallel to each otherly press straight-though arrangement, described drg comprises the rope gripper rotated around anchor shaft 21 and the dynamic resistance device stopping the described rope gripper in location.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 rope clamping block 2, and anchor shaft 21 is provided with retracing spring.Two rope clamping blocks keep at a certain distance away relatively and establish, opposite face is evagination arcwall face, middle formation one strip crack 6, and described crack 6 is symmetrical perpendicular to the sectional axis of anchor shaft 21, and large centre, two is little, middle minimum place width is the diameter of a hoist ropes 1.Described rope clamping block 4 is relative to the exterior bottom of rope clamping block 2, and the both sides along anchor shaft 21 direction are respectively provided with an electromagnet catch 41.Two stoppers 8 that described dynamic resistance device comprises wedge shaped support block 10 and is located on back-up block 10 inclined-plane, two stoppers 8 are corresponding with described two electromagnet catch 41 along the position in anchor shaft 21 direction, stopper 8 comprises the magnetic wedge form drag stopper 81 being located at its top, and shape, the size of described two electromagnet catch 41 match with the blocking surface 811 of two stop parts 81 is corresponding respectively.Two rope clamping blocks are connected along the two in described crack 6 direction respectively by connecting strap 12 correspondence, and described along crack 6 direction every is being provided with a connecting piece 12 along the two ends in anchor shaft 21 direction.The lateral surface correspondence perpendicular to anchor shaft 21 of two rope clamping blocks flushes, and rope clamping block is greater than the width of described row's hoist ropes 1 along the vertical distance between the connecting strap 12 at the two ends in anchor shaft 21 direction.Described wedge shaped support block 10 longitudinally hollows out between two resistance stoppers 8, convenient arrangement hoist ropes 1.
During installation, by the crack 6 of the hoist ropes 1 of a row 3 longitudinal extensions through 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 made to be positioned on the circumferential turned position of electromagnet catch 41, two stop parts 81 are corresponding respectively along the position of anchor shaft 21 axis with two electromagnet catch 41, and the blocking surface 811 of stop part 81 is relative with corresponding electromagnet catch 41, and electromagnet catch 41 bottom height is lower than corresponding stop part 81 tip height.One row's hoist ropes 1 is through two stoppers 8, and cut-out on back-up block 10, during normal work traction, can not be subject to the impact of retaining means.As necessary by electromagnet catch 41 attraction with magnetic stop part 81, drive rope gripper to rotate, the cross travel of crack 6 width gradually, round and smoothly to diminish, clamping hoist ropes 1, electromagnet catch 41 is braked static by stop part 81; Power-off, removes electromagnetic force, and rope gripper answers initial position next time in the effect of retracing spring, and retracing spring also serves buffer action, protective folder rope device simultaneously.Connecting strap 12 on two rope clamping blocks not only plays connection function, and can also prevent hoist ropes 1 from skidding off drg along anchor shaft 21 direction, safer, braking effect is better simultaneously.
Above according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, related personnel in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification sheets, must determine technical scope according to right.
