Description
Technical field
The utility model relates to a kind of safety interaction device of Elevator weight sensor.
Background technology
Along with the progress of society, the increasing of population, the quantity of skyscraper sharply increases, and the use amount of elevator also significantly increases thereupon.Traction elevator is present the most common a kind of elevator, and the traction steel-cable two ends connect car and counterweight respectively, relies on the lifting of the frictional force drives car between steel rope and the traction sheave grooving; Wherein the effect of counterweight is the weight of balance car, reduces the load of towing machine, realizes the energy-conservation of elevator, its weight equals half that the car deadweight adds the elevator rated load, nominal load, when there is remarkable space the elevator hoistways below, in case Elevator weight sensor falls, may cause casualties.
Safety tongs device is a kind of safety device that present Elevator weight sensor generally adopts, when faults such as hypervelocity appears in counterweight, the rope that breaks, elevator governor drives the safety tongs action, and counterweight is clamped on the guide rail, safety switch cuts off the safety return circuit of control system simultaneously, avoids the generation of accident.Safety tongs and the safety switch of the counterweight of existing elevator trigger by different modes, and the mechanical action inaccurate coordination can't be given full play to the safeguard function of counterweight safety device.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of Elevator weight sensor safety interaction device, can trigger safety tongs and safety switch simultaneously, improves both coordinations, gives full play to the safeguard function of counterweight safety device.
The utility model is achieved through the following technical solutions:
Elevator weight sensor safety interaction device, comprise the safety tongs that is connected in the counterweight frame curb girder, and the safety switch that is connected in the counterweight frame entablatrance, also comprise the parallel gangbar that is connected in the counterweight frame entablatrance, described gangbar two ends are respectively equipped with driving lever, the lower end of described driving lever is connected with the movable voussoir of safety tongs respectively, is connected in gangbar and wherein connects elevator speed limit rope by lifting rod in the driving lever upper end of an end; Be provided with also on the described gangbar that switch re-packs and torsion spring, described switch re-packs and is connected with safety switch, and torsion spring is connected with entablatrance.
The further improvement of the utility model scheme is, be fixedly connected with fixed support and switch bracket on the counterweight frame entablatrance, gangbar is rotationally connected with fixed support and switch bracket, safety switch is fixedly connected on switch bracket, torsion spring is socketed on the gangbar, described torsion spring one end is fixedly connected on gangbar, and the other end is fixedly connected on fixed support.
The further improvement of the utility model scheme is that the movable voussoir of safety tongs flexibly connects by circular shaft pin and driving lever.
The further improvement of the utility model scheme is, lifting rod is captiveed joint with the driving lever upper end by set pin, and the upper end of lifting rod is connected with elevator speed limit rope.
The utility model advantage compared with prior art is:
One, makes safety tongs and safety switch synchronization action, give full play to the safeguard function of counterweight safety device;
Two, safety tongs is fixed on curb girder, gangbar is connected in entablatrance by support, does not influence counterweight framework integral structure;
Three, simple in structure, part is few, is convenient to produce, installs and transportation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A direction view of Fig. 1.
1 is lifting rod; 2 is fixed support; 3 is entablatrance; 4 is gangbar; 5 is torsion spring; 6 is driving lever; 7 is safety tongs; 8 is curb girder; 9 is the rope sheave assembly; 10 for re-packing; 11 is switch bracket; 51 is set pin; 52 is the circular shaft pin; 61 is safety switch.
The specific embodiment
Elevator weight sensor safety interaction device, comprise the safety tongs 7 that is connected in counterweight frame curb girder 8, and the safety switch 61 that is connected in counterweight frame entablatrance 3, also comprise the parallel gangbar 4 that is connected in counterweight frame entablatrance 3, be fixedly connected with fixed support 2 and switch bracket 11 on the described counterweight frame entablatrance 3, gangbar 4 is rotationally connected with fixed support 2 and switch bracket 11, and safety switch 61 is fixedly connected on switch bracket 11; Described gangbar 4 two ends are respectively equipped with driving lever 6, the lower end of described driving lever 6 flexibly connects by the movable voussoir of circular shaft pin 52 with safety tongs 7 respectively, be connected in gangbar 4 and wherein be connected with lifting rod 1 by set pin 51 in driving lever 6 upper ends of an end, the upper end of described lifting rod 1 is connected with elevator speed limit rope; Also be provided with switch on the described gangbar 4 and re-pack 10, described switch re-packs and 10 is connected with safety switch 61; Torsion spring 5 is socketed on the gangbar 4, and described torsion spring 5 one ends are fixedly connected on gangbar 4, and the other end is fixedly connected on fixed support 2.
When elevator speed occurs unusual, the elevator governor action, by the elevator speed limit rope tractive lifting rod 1 that makes progress, driving lever 6 drives gangbar 4 rotations under the effect that lifting rod 1 makes progress, thereby drive switch and re-pack 10 and another driving lever 6 actions of being arranged at gangbar 4 other ends, switch re-packs 10 with safety switch 61 disconnections, thereby cuts off the control system safety return circuit, and driving lever 6 is mentioned the voussoir of safety tongs 7 simultaneously, counterweight is clamped on the guide rail, makes elevator out of service.
