Abstract
The present invention provides a rope breakage protector of traction ropes of an elevator cage, which is composed of safety tongs, a support frame, a contact plate, a base plate, a transmission arm, etc. The protector has the characteristic that the protector can protect elevators with a plurality of traction ropes against rope breakage, and solves the problem that the protectors can only protect elevators with one traction rope against the rope breakage existing in the prior art.
Description
The present invention relates to the safety guard of elevator.
Application number provides the device of a kind of " a kind of safety device for cage of elevator in case of cable breaking " by name for the Chinese patent application of " 92102729.X ".This device mainly comprises: safety tongs, disconnected rope detects partly, support, lever and T oblique crank Z etc.Because as long as it just can implement breaking rope protecting, stop elevator when wherein one fractures, thereby it has the advantage that can make elevator move more reliable and saferly in many hoist ropes of lift car.But this fender guard also exists following deficiency: actual its hoist ropes of employed elevator often is not one group but organizes more.Some hydraulic elevators for example, its each angle just has one group of (two every group or three) hoist ropes drawing.If use above said fender guard to implement breaking rope protecting, obviously it is difficult to be competent at.
The purpose of this invention is to provide a kind of more later-model lift car hoist ropes rope broken protector, it can implement the actv. breaking rope protecting to the elevator with many group hoist ropes.
The present invention will be described below in conjunction with accompanying drawing.
What accompanying drawing provided is the structural representation of the said lift car hoist ropes of the present invention rope broken protector.Major part of the present invention comprises the safety tongs (safety tongs does not draw in the accompanying drawing) more than two, the transmission rope 1 that links to each other with safety tongs with the corresponding one end of safety tongs number more than two, support 2, touch panel 3, the seat board 4 in tape spool hole, the corresponding wheel flutter 6 of the number of wheel flutter 5 and plural and safety tongs, the centre is processed with axis hole and also is processed with the fixed cover 7 in several hole of beads all around, spring perch 8, some steel balls 9, the axle 10 of band groove A, transmission arm 11, spring 12,13, be processed with in it taper hole B with and outside sliding sleeve 14 that also is processed with a protuberance C and axle bumper spare 15 etc.Clear for accompanying drawing is represented, this accompanying drawing does not draw the other end and the spring 12 of the transmission rope 1 of fender guard right-hand part, wheel flutter 6, spring perch 8, transmission arm 11.The mode of aforementioned each component set-up fender guard is: spring perch 8, fixed cover 7 and wheel flutter 5,6 all are fixedly mounted on the seat board 4; Fixed cover 7 its axis holes that are installed on the seat board 4 communicate with axis hole on the seat board 4; Spring 12 is sleeved on the spring perch 8; Spring 13 is sleeved on the fixed cover 7, and axle 10 is arranged in the axis hole of fixed cover 7 and seat board 4, the middle part of one end and transmission arm 11 other end assembly axis block piece 15 that is fixedly linked, and plurality of steel balls 9 is separately positioned in some balls hole on the fixed cover 7; Sliding sleeve 14 is sleeved on spring 13 and the fixed cover 7; One end of touch panel 3 is connected with 2 on support on the protuberance C that its other end is overlapped on sliding sleeve 14; The end that transmission rope 1 does not link to each other with safety tongs is fixedly linked by the end of wheel flutter 6 with transmission arm 11.
Use above-mentioned this safety guard to implement breaking rope protecting, can use a transmission rope 16, the one end then is fixedly linked by the hoist ropes of other track adjusting wheel and elevator by track adjusting wheel 5 and touch panel 3 other end that is fixedly linked.The T oblique crank Z of a band of elevator rope and the use that should take as shown in the figure being connected of lift car spring connects the mode of part.The principle of work of its breaking rope protecting is: when the hoist ropes of certain root lifting lift car fractures; T oblique crank Z upper spring as attaching parts between elevator rope and the lift car; to tear touch panel 3 by transmission rope 16 moves down sliding sleeve 14; at this moment; taper hole B on the sliding sleeve 14 exposes; steel ball 9 is to outer rolling; transmission arm 11 loses the steel ball screens because of the axle 10 that is fixedly linked with it; and under the effect of spring 12 by jack-up; to be torn the safety tongs action by transmission rope 1 by the transmission arm 11 of jack-up, on the guide rail of lift car stop in elevator hoistways.
This lift car hoist ropes rope broken protector provided by the invention has solved the problem that prior art can not be carried out breaking rope protecting to the elevator with several groups of hoist ropes.Simultaneously, it also has simple in structure, the advantage of reliable operation.
Below the invention will be further described.
Transmission arm 11 is that the center can be made double-arm and also can be made multi-arm with axle 10, and people can correspondingly increase wheel flutter 6 and the transmission rope 1 on the seat board 4 when making multi-arm, can make this device remove to control a plurality of safety tongss by them and carry out breaking rope protecting.Axle bumper spare 15 can adopt nut, and it is convenient to people and adjusts transmission arm 11 by the height of jack-up.Transmission rope 1 and transmission rope 2 all can adopt steel rope.
