Abstract
The utility model discloses an elevator towline rope breakage protection device, be in including base, the setting of seting up the through-hole the base on switch support frame, set up and be in switch support frame on and be connected with the elevator switch board, set up at every elevator towline tip and pass the base on rope fastening, the setting of through-hole be in all the rope fastening with base between rope fastening spring, rotatable setting be in switch support frame on the switch bottom plate, all rope fastening connect be in switch bottom plate on, switch bottom plate on lie in switch department be provided with the switch clapper. The device simple structure, reliable operation can detect the fracture or not hard up of an arbitrary towline to remind operating personnel to in time overhaul the towline, prevent the trouble in the bud.
Description
Technical field
The utility model relates to a kind of annex of elevator, especially a kind of detecting device that is used to detect traction type elevator towline fracture or relaxation cases.
Background technology
Elevator, especially traction elevator are to rely on the pulling force of many hoist ropes to do the vertical takeoff and landing (VTOL) operation aloft, in case hoist ropes ruptures, might cause casualties, consequence such as device damage.All can be furnished with velocity limiter on the general elevator, when the descending speed of car surpassed certain value, velocity limiter can drive the safety tongs action, and car is clamped on the guide rail.Sometimes an a certain hoist ropes also can rupture or lax situation, though design engineer all can design the strength margin of hoist ropes to such an extent that surpass 12 when design, yet the fracture of a certain hoist ropes or relaxation cases also might cause serious consequence, must take preventive measures.
The patent No. is the patent of invention of " ZL93101201.5 "; announced a kind of " lift car hoist ropes rope broken protector " that has with major parts such as the corresponding multigroup safety pincers of hoist ropes, support, touch panel, seat board, transmission arms; when a certain hoist ropes takes place to rupture or be loosening, utilize the physical construction that is connected with hoist ropes to tear safety tongs with the car stop.Along with the development of elevator control technology, the control method of electric replaces this mechanical control method gradually, and electric control is more simple in structure, reliability is high.
Number of patent application is the utility model patent " jacking system hoist ropes rope break detection device " of " ZL200620083717.8 ", the every all corresponding cover detecting device of hoist ropes, controlled device that can detection signal is independent adopts, also detection signal can be chained together is used, in time to detect the disconnected rope situation of hoist ropes accurately.Yet for the arrangement space of this anxiety of elevator, every hoist ropes all must be equipped with a cover detecting device, and difficulty in arrangement, cost increase.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of simple in structure, reliable operation, can detect the fracture of any hoist ropes or loosening elevator rope rope broken protector.
The purpose of this utility model is achieved in that a kind of elevator rope rope broken protector, comprise the pedestal that offers through hole, be arranged on switch bracing frame on the described pedestal, be arranged on switch adapter plate on the described switch bracing frame, be arranged on the switch that is connected with elevator control cabinet on the described switch adapter plate, be arranged on every elevator rope one end and pass the through hole on the described pedestal fag end, be arranged on the rope head spring between all described fag ends and the described pedestal, described switch has only one; Described elevator rope rope broken protector also comprises the rotating switch baseplate that is arranged on the described switch bracing frame; described all fag ends all are fixedly coupled on described switch baseplate, are positioned at described switch place on the described switch baseplate and are provided with switch and re-pack.The re-pack opposed end place of the end that is rotationally connected that is arranged on described switch bracing frame and described switch baseplate of described switch.
Because the utilization of technique scheme the utlity model has following advantage: this device can detect the fracture of any hoist ropes or become flexible, thereby reminds operating personal that hoist ropes is in time overhauled, and takes preventive measures.
Description of drawings
Fig. 1 front view of the present utility model.
Wherein, 1, elevator control cabinet, 2, the switch adapter plate, 3, fag end, 4, the switch bracing frame, 5, pedestal, 6, rope head spring, 7, switch, 8, switch re-packs, 9, switch baseplate.
The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail: a kind of elevator rope rope broken protector; comprise the pedestal that offers through hole 5 that is arranged on car or the counterweight; be arranged on the switch bracing frame 4 on the described pedestal 5; be arranged on the switch adapter plate 2 on the described switch bracing frame 4; be arranged on the switch 7 that is connected with elevator control cabinet 1 on the described switch adapter plate 2; be arranged on every elevator rope one end and pass the fag end 3 of the through hole on the described pedestal 5; be arranged on the rope head spring 6 between all described fag ends 3 and the described pedestal 5, described rope head spring 6 is in compressive state.Described switch 7 of the present utility model has only one; The rotating switch baseplate 9 that is provided with on the described switch bracing frame 4, described all fag ends 3 all are fixedly coupled on described switch baseplate 9, are positioned at described switch 7 places on the described switch baseplate 9 and are provided with switch and re-pack 8.The described switch 8 opposed end places that are arranged on described switch bracing frame 4 and the end that is rotationally connected of described switch baseplate 9 that re-pack.
When each root hoist ropes all during in tension, the rope head spring 6 at described fag end 3 places of each root hoist ropes all is in confined state, and described switch baseplate 9 is owing to the pulling force of hoist ropes is fitted on the described switch bracing frame 4.If fracture or loosening takes place in a certain hoist ropes; the rope head spring 6 at described fag end 3 places of this hoist ropes outwards supports described switch baseplate 9 and opens; make described switch re-pack and 8 touch described switch 7; described elevator control cabinet 1 obtains after the signal of described switch 7; to produce warning, and require elevator to shut down maintenance.
In general, if fracture or loosening takes place in parts such as the fag end of elevator, hoist ropes, by observing or using simple tools just can detect, all be equipped with the mode of switch for relatively each root hoist ropes, the method that the utility model adopted is more simple in structure, arrangement convenience, safe and reliable.
