Description

A kind of disconnected protective device of elevator rope pine

Technical field

The utility model provides a kind of disconnected protective device of elevator rope pine, to solve the damage monitoring of elevator rope The technical issues of caused elevator safety reliability is unable to satisfy demand not in time.

Background technique

Elevator industry develops rapidly in recent years, and elevator applications are increasing, and the safety accident as caused by elevator faults is not It is disconnected to occur, very big damage is brought to people life property safety, so requiring to be continuously improved to the security performance of elevator.Elevator, Especially traction elevator mainly makees vertical rise and fall operation by the pulling force of more hoist ropes in the sky, once hoist ropes occurs Fracture, it would be possible to cause casualties, the serious consequences such as equipment damage.When disconnection or traction occur for traction type elevator towline When the unsafe conditions such as the caused loosening of abnormal elongation of restricting, elevator can be effectively prevented to run under this kind of situation, this direct relation To the service performance of elevator and the security of the lives and property of passenger.

Current traction elevator is during vertical lift, after the abrasion of longtime running hoist ropes, under certain conditions, meeting Lead to hoist ropes abrasion elongation, or even fracture, carriage is caused to fall and personnel casualty accidents.The security and stability of elevator can not be protected Card.The utility model patent for this problem, proposes a kind of vertical lift type elevator safety stability of can effectively improve Hoist ropes pine is broken protective device.

Utility model content

The purpose of this utility model is to provide a kind of disconnected protective devices of elevator rope pine.

The utility model is implemented by following technical solution: elevator rope pine is broken protective device, including safety switch 1, is hit Bow 2, pin shaft 4, hits bow bracket 5, operating spring 6, fixed spring 7, switch bracket 8, spring base 9, rope hitch plate 10 at rope end 3.Work as electricity When the unsafe conditions such as loosening caused by disconnection or hoist ropes abnormal elongation occur for terraced hoist ropes, effect of the rope end 3 in operating spring 6 Do flood tide rebound upwards down, hit bow 2 moments jacked up by operating spring 6, with pin shaft 4 be fulcrum rotate, and then hit bend 2 bending Structure can trigger the switch triggering portion of safety switch 1, and safety switch 1 is connected in control circuit, once safety switch 1 is touched Dynamic, elevator stops and alarms；The device is able to detect that the fracture or loosening of any one hoist ropes, to remind operator Member overhauls hoist ropes in time, takes preventive measures, plays early warning defencive function.

The safety switch 1 is installed on elevator rope head plate 10 by switch bracket 8, and it is rotatable by pin shaft 4 to hit bow 2 It is installed to and hits on bow bracket 5, the other end is fixed by fixed spring 7.6 lower end of operating spring is placed on the counterbore of rope hitch plate In, upper end and spring base 9 cooperate, and hit bow main part and be correspondingly placed on 9 shoulder of spring base, therefore hit bow 2 below by bullet Spring abutment 9 is fixed, and both ends are fixed by previously described pin shaft 4 and fixed spring 7.The cooperation of rope end 3 is placed on spring base 9 Face, the protective device of complete set is installed on rope hitch plate in summary.When elevator rope is normal, switch triggering portion and peace Full switch keeps working normally distance, and elevator works normally.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts Every other embodiment obtained, fall within the protection scope of the utility model.

Elevator rope pine as shown in Figure 1 is broken protective device, including safety switch 1, is hit bow 2, rope end 3, pin shaft 4, hit Bend bracket 5, operating spring 6, fixed spring 7, switch bracket 8, spring base 9, rope hitch plate 10.Safety switch 1 passes through switch bracket 8 It is installed on elevator rope head plate 10, hits bow 2 and be rotatably mounted to hit on bow bracket 5 by pin shaft 4, the other end is by fixed spring 7 is fixed.6 lower end of operating spring is placed in the counterbore of rope hitch plate, and upper end and spring base 9 cooperate, and hit bow main part It is correspondingly placed on the shoulder of spring base 9, therefore hits bow 2 and fixed below by spring base, two ends are by previously described rotating pin 4 It is fixed with fixed spring 7.The cooperation of rope end 3 is placed on above spring base 9, and the protective device of complete set is mounted on rope in summary In head plate.

When elevator rope is normal, the bending part and safety switch for hitting bow 2 keep working normally distance, and elevator is normal Work.When the unsafe conditions such as the loosening caused by disconnection or hoist ropes abnormal elongation occur for elevator rope, rope end 3 is in movement bullet Flood tide rebound is done under the action of spring 6 upwards, hit 2 moments of bow is jacked up by operating spring 6, is that fulcrum rotates with pin shaft 4, and then hits bow 2 bending structure can trigger the switch triggering portion of safety switch 1, and safety switch 1 is connected in control circuit, once safety open It closes 1 to be touched, elevator stops and alarms；The device is able to detect that the fracture or loosening of any one hoist ropes, to mention The operator that wakes up overhauls hoist ropes in time, takes preventive measures, plays early warning defencive function.
