Description
Technical field
The utility model relates to the electronic protection equipment of construction landing machine, the disconnected rope of especially a kind of building hoist protective device.
Background technology
In building hoist, need to there is counterweight to reduce output power of motor to save electric energy.Elevator craning cage connects counterweight by two steel ropes; in use, fracture likely appears in steel rope, for safety; be provided with protection device for preventing wire rope breaking at existing upgrading machine cage tip position; this device has been installed limit switch on the eccentric rope tool, and during wire cable rupture, the eccentric rope tool falls toward a side, touches limit switch work; cut off the electricity supply; cage stops moving up and down, and the limit switch control line connects with wire, in access cage control box.But above-mentioned protection device for preventing wire rope breaking is only applicable to the building hoist of counterweight external, reason is the built-in counterweight armored rope cage of counterweight special-purpose hoisting mechanism for end, and the anti-break rope limit switch can't be installed.
The utility model content
This practical purpose is to provide the disconnected rope of a kind of building hoist protective device, and applied widely, disconnected rope is quick on the draw.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: the disconnected rope of a kind of building hoist protective device, comprise cage and counterweight, connecting steel wire ropes between cage and counterweight, the counterweight end is provided with a jam nut, jam nut is connected and fixed axle by a spring, anchor shaft is provided with suspension ring, and described steel rope one end is provided with hook, and hook connecting is on described suspension ring, described jam nut is provided with limit switch, limit switch access elevator work loop.When steel rope occurs rupturing or is loosening, jam nut also becomes flexible, trigger limit switch, cut off upgrading machine work loop, the cage of elevator stops up-and-down movement, because limit switch is arranged on the counterweight end, no matter be that the built-in building hoist of counterweight external and counterweight is all applicable, Applicable scope increases, once steel rope goes wrong, jam nut reacts rapid sensitive.
As preferably, described limit switch comprises the wireless remote sensing limiting device and is arranged on wireless control switch on elevator work loop, and wireless remote sensing limiting device fire switch signal is to wireless control switch.Due at counterweight end mounting limit switch, if adopt wired connection mode, need between the work loop in limit switch and cage, wire be set, counterweight is moved up and down, wire is easily pulled apart, and adopts wireless mode to prevent the above-described problem from occurring.
As preferably, described limit switch is a remote sensing relay, and the wireless signal transmission end of remote sensing relay is located on described jam nut, and the master cock of remote sensing relay is connected on elevator work loop.Adopt the remote sensing relay, connection and control method are all simpler, simplify circuit layout.
As preferably, the power supply in described elevator work loop connects a Switching Power Supply, and described remote sensing relay and Switching Power Supply are electrically connected to.From the elevator loop, power taking, for the work of remote sensing relay, is further simplified circuit.
As preferably, described spring is returning spring, coats spring housing on returning spring, can stablize connection structure.
After adopting technique scheme, the utlity model has following outstanding advantages: limit switch is arranged on to the junction of counterweight end and steel rope, not only can guarantees short rope form condition is made to reaction fast and accurately, and also applied widely, be not subject to structural limitations; Adopt wireless mode to be controlled limit switch, saved the connection wire, prevented that counterweight from pulling apart wire when up-and-down movement.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
Fig. 1 is that the utility model is at counterweight end assembly drowing;
Fig. 2 is the utility model circuit diagram.
The specific embodiment
As shown in Figure 1, the disconnected rope of a kind of building hoist protective device, comprise cage and counterweight, between cage and counterweight, connecting steel wire ropes 1, the counterweight end is provided with a jam nut 2, jam nut 2 is connected and fixed axle 4 by a spring 3, anchor shaft 4 is provided with suspension ring, described steel rope 1 one ends are provided with hook 6, hook connecting is on described suspension ring 5, and described jam nut is provided with limit switch 7, limit switch access elevator work loop, described spring can adopt returning spring in the present embodiment, coats spring housing 31 on returning spring to stablize connection structure.When fracture or loosening please condition the time appears in steel rope 1, jam nut 2 also can be loosening along with producing, the limit switch 7 be positioned on jam nut just is touched, limit switch also can adopt the machinery of spring loaded to touch mode, by limit switch, elevator work loop is cut off, the operation up and down of system for stopping elevators cage, prevent that safety misadventure from occurring, the junction limit switch that is arranged on counterweight end and steel rope is not subject to the structural limitations of elevator, can guarantee short rope form condition is made to reaction fast and accurately, applied widely.
As shown in Figure 2, described limit switch comprises wireless remote sensing limiting device and be arranged on wireless control switch on elevator work loop, and wireless remote sensing limiting device fire switch signal is to wireless control switch.Transmit fracture or the loosening signal of steel rope with wireless mode, saved the wire that connects limit switch and elevator work loop, prevent that elevator craning cage from pulling apart wire in upper and lower operational process.
In the present embodiment, described limit switch is preferably a remote sensing relay, and the wireless signal transmission end K1 of remote sensing relay is located on described jam nut, and the master cock Q1 of remote sensing relay is connected on elevator work loop.The power supply in described elevator work loop connects a Switching Power Supply 8, and described remote sensing relay and Switching Power Supply are electrically connected to.Switching Power Supply 8 is supplied with the work of remote sensing relay from the power supply power taking in elevator work loop, can simplify circuit, the remote sensing relay application is in the present embodiment, circuit structure is simple and practical, control also more conveniently, wireless signal transmission end K1 sends wireless control signal according to the steel rope state of jam nut reflection to master cock Q1.
Except above preferred embodiment, the utility model also has other embodiment, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
