Abstract
The invention provides a loosening and breaking protection device for a steel wire rope of an elevator and aims at solving the technical problem that damage monitoring of the steel wire rope of the elevator is not in time to make the safe reliability of the elevator not meet the needs. According to the technical scheme, the loosening and breaking protection device for the steel wire rope of the elevator comprises the steel wire rope of the elevator and is characterized in that a first magnet is arranged on one side of the steel wire rope of the elevator and is in a U shape; the steel wire rope of the elevator is embedded into a groove of the first magnet; a second magnet is fixed outside a notch of the first magnet; an insulation interlayer is arranged at the contact part of the first magnet and the steel wire rope of the elevator; and the first magnet is connected with a safety switch. The loosening and breaking protection device has the beneficial effects of a compact structure, small and exquisite appearance, rapidness and accuracy in installation, capability of reusing, low cost, providing convenience and help for detection of breaking of the steel wire rope of the elevator and eliminating accident hidden dangers caused by breaking of the steel wire rope of the elevator in the first time.
Description
Technical field
The present invention relates to elevator technology field, be specifically related to a kind of elevator wire rope pine and break protection device.
Background technology
Along with elevator industry develops rapidly, many elevator safety problems are the most increasingly paid close attention to by masses.Elevator is in running, and steel wire rope there will be fracture of wire, disconnected stock, broken lot phenomenon, and this directly affects the safe operation of elevator.Repair and maintenance personnel are very different for elevator, during repair and maintenance, the inspection of steel wire rope lacked corresponding equipment, easily ignore show with potential problem.Only relying on bimonthly repair and maintenance and carry out hand inspection, reliability, promptness all can not meet current demand.It is known that safety tongs limiter of speed is the safety guard of elevator, when elevator wire rope complete rupture causes elevator overspeed to run, play brake protective effect.When steel wire rope portion fractures, owing to car does not exceeds the speed limit, limiter of speed safety tongs is inoperative, and at this moment, safety guard is just particularly important.Existing major part elevator is all not provided with this protection device.Break at steel wire rope can swipe in hoistway miscellaneous part, run, to elevator, the hidden danger that causes the accident.
Summary of the invention
The invention provides a kind of elevator wire rope pine to break protection device, the elevator safety reliability caused not in time to solve the damage monitoring of elevator wire rope cannot meet the technical problem of demand.
In order to solve above-mentioned technical problem, the present invention adopts the following technical scheme that
A kind of elevator wire rope pine is broken protection device; including elevator wire rope (1); it is characterized in that; the side of described elevator wire rope (1) arranges the first magnet (2); described first magnet (2) is shaped as spill; described elevator wire rope (1) embeds in the groove of the first magnet (2); recess extenal fixation the second magnet (3) at the first magnet (2); the position that described first magnet (2) contacts with elevator wire rope (1) arranges interlayer insulating layer, described first magnet (2) attachment security switch (4).
Further, described safety switch (4) is connected in loop of the door lock, makes safety return circuit disconnect by magnet is attracting, and the switch board of elevator receives safety return circuit cut-off signal, reach the purpose that power-off is stopped, thus the very first time eliminates the accident potential that elevator causes due to this reason.
Further, described first magnet (2) connects spacing slide rail (5), and the direction of spacing slide rail is identical with the recess direction of described first magnet (3).
Further, the material of described interlayer insulating layer is rubber.
Further, it is characterised in that described first magnet (2) is electrically non-conductive material.
Further, the position that described first magnet (2) is connected with safety switch (4) arranges rubber.
The present invention is based on deformation principle, when elevator wire rope is normal, the first magnet is blocked by elevator wire rope, it is impossible to displacement, when elevator wire rope pine is broken, two magnets are attracting, and the second magnet is fixing, and the first magnet produces displacement, open safety switch, the switch board of elevator receives safety return circuit cut-off signal, reaches the purpose that power-off is stopped, thus the very first time eliminates the accident potential that elevator causes due to this reason.
Beneficial effects of the present invention: present configuration is compact, low-profile, install quick and precisely, can reuse, low cost, for elevator wire rope break rope detection provide convenience and help, the very first time eliminates the accident potential that elevator causes due to this reason.
Accompanying drawing explanation
The invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings:
Fig. 1 is the schematic diagram of the present invention.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
A kind of elevator wire rope pine is broken protection device; including elevator wire rope (1); it is characterized in that; the side of described elevator wire rope (1) arranges the first magnet (2); described first magnet (2) is shaped as spill; described elevator wire rope (1) embeds in the groove of the first magnet (2); recess extenal fixation the second magnet (3) at the first magnet (2); the position that described first magnet (2) contacts with elevator wire rope (1) arranges interlayer insulating layer, described first magnet (2) attachment security switch (4).
Further, described safety switch (4) is connected in loop of the door lock, makes safety return circuit disconnect by magnet is attracting, and the switch board of elevator receives safety return circuit cut-off signal, reach the purpose that power-off is stopped, thus the very first time eliminates the accident potential that elevator causes due to this reason.
Further, described first magnet (2) connects spacing slide rail (5), and the direction of spacing slide rail is identical with the recess direction of described first magnet (3).
Further, the material of described interlayer insulating layer is rubber.
Further, it is characterised in that described first magnet (2) is electrically non-conductive material.
Further, the position that described first magnet (2) is connected with safety switch (4) arranges rubber.
The present invention is based on deformation principle, when elevator wire rope is normal, the first magnet is blocked by elevator wire rope, it is impossible to displacement, when elevator wire rope pine is broken, two magnets are attracting, and the second magnet is fixing, and the first magnet produces displacement, open safety switch, the switch board of elevator receives safety return circuit cut-off signal, reaches the purpose that power-off is stopped, thus the very first time eliminates the accident potential that elevator causes due to this reason.
The foregoing is only presently preferred embodiments of the present invention, be not limited to the scope that the present invention implements, the equivalence change made according to scope of the present invention patent and description and modification, should be included within the scope of the present invention.
