Abstract
With the elevator machinery range limiter of system reliable behavior indicator lamp.Major part crane travelling limiter control path has damaged or after the non-Access Control cabinet of control loop, has caused range limiter to perform practically no function, and adds the hazard level that installations and facilities are run.The utility model composition comprises: limiting device top panel, described limiting device top panel (1) and status indicator lamp A(14) be connected, described limiting device top panel (1) is connected with limiting device right panel (5), described limiting device right panel (5) is connected with roller swing arm (4), and described roller swing arm (4) is connected with contact switch (16); Described contact switch (16) and described status indicator lamp A(14) be connected in normally closed contact circuit (20), described normally closed contact circuit (20) is through current transformer (13).The utility model is used for the spacing of elevator machinery stroke.
Description
technical field:
the utility model relates to a kind of elevator machinery range limiter with system reliable behavior indicator lamp.
background technology:
elevator machinery is as lifting appliance important in major industry production, metallurgical technology, mechanical equipment, and therefore enterprise is also higher to the requirement of its safety and reliability.There is range amplitude in elevator machinery operational process, when elevator machinery horizontal displacement needs restraint in process of production, often use range limiter, installations and facilities safe operation can be ensured by the constraint of limiting device.Range limiter also can be used on other equipment such as movable operating platform rail flanges.
range limiters all on the market can reach due effect, but Problems existing is at present: find in enterprise is to weight-lifting equipment periodic inspection, major part crane travelling limiter control path has damaged or the non-Access Control cabinet of control loop, range limiter is caused to perform practically no function, whether range limiter is in normal working in the course of the work can not clearly be indicated, and adds the hazard level that installations and facilities are run.For machine operator or director, can not judge whether limiting device is in normal working timely and effectively, consequence be make to run to end position cart cannot orderly shutdown, finally can affect operation security and the efficiency of operation of enterprise.
utility model content:
the purpose of this utility model is to provide a kind of elevator machinery range limiter with system reliable behavior indicator lamp.
above-mentioned object is realized by following technical scheme:
a kind of elevator machinery range limiter with system reliable behavior indicator lamp, its composition comprises: limiting device top panel, described limiting device top panel is connected with status indicator lamp A, described limiting device top panel is connected with limiting device right panel, described limiting device right panel is connected with roller swing arm, described roller swing arm is connected with contact switch, described contact switch and described status indicator lamp A are connected in normally closed contact circuit, and described normally closed contact circuit is through current transformer.
the described elevator machinery range limiter with system reliable behavior indicator lamp, described contact switch and status indicator lamp B are connected in parallel in open contact circuit, and described open contact circuit is through voltage transformer.
beneficial effect:
1. the utility model has Chang Kai and normally closed multiple contact limit switch, inner integrated transformer, induces electric current (voltage) drive the secretly bright of luminous element by line-internal electric current (voltage).Through current transformer on normally closed contact circuit, open contact two ends are parallel with voltage transformer, and the secondary winding coil of transformer is connected with a luminous element.When equipment needs to utilize normally closed contact wiring, current transformer inducing current makes luminous element (status indicator lamp A) luminous, and this state indicates normally closed connection good; When equipment needs to utilize open contact to connect, voltage transformer induced voltage makes connected luminous integrated component (status indicator lamp B) luminous, and this state instruction normally opened track circuit is good; Namely use open contact for equipment component and also use normally closed contact wiring, then all the whole status line of luminous instruction is good for two indicator elments.Inhibiting device touch time, the rear indicator light normal luminous of the of short duration dimmed reset of status indicator lamp.
the utility model adds status indicator lamp in original range limiter, directly demonstrates position limiter device whether be in normal working by the light on and off of indicator lamp.Overcome existing limiting device shortcoming, utilize transformer principle that luminous element is arranged on limiting device top cover, make staff be judged the safety case of whole system before operating it by the light on and off signal observing luminous element.Showing whole position limitator when luminous element is luminous is in good operation conditions; Illustrating that limiting device lost efficacy when observing before operation when luminous element does not work, whole system safe operation can not be ensured.Luminous element is arranged on and protrudes from limiting device shell surface, increases light-emitting area and operating personal is more easily identified.During application the utility model, elevator machinery safe operation can be ensured.
accompanying drawing illustrates:
accompanying drawing 1 is the structural representation of the utility model double-contact range limiter.
accompanying drawing 2 is lateral plans of accompanying drawing 1.
accompanying drawing 3 is inner schematic diagrams of the present utility model.
detailed description of the invention:
embodiment 1:
a kind of elevator machinery range limiter with system reliable behavior indicator lamp, its composition comprises: limiting device top panel, described limiting device top panel 1 and status indicator lamp A, piece number: 14 connect, described limiting device top panel 1 is connected with limiting device right panel 5, described limiting device right panel 5 is connected with roller swing arm 4, described roller swing arm 4 is connected with contact switch 16, described contact switch 16 and described status indicator lamp A, piece number: 14 are connected in normally closed contact circuit 20, described normally closed contact circuit 20 is through current transformer 13.
when elevator machinery arrives maximum travel position, described roller swing arm 4 is pushed, and the moving contact 10 of contact switch 16 is disconnected, status indicator lamp A, piece number: 14 is dimmed with break back contact 17.
embodiment 2:
with the elevator machinery range limiter of system reliable behavior indicator lamp, described contact switch 16 and described status indicator lamp B, piece number: 15 are connected in parallel in open contact circuit 19, described open contact circuit 19 is through voltage transformer 12.
when elevator machinery arrives maximum travel position, described roller swing arm 4 is pushed, and the moving contact 10 of contact switch 16 is connected, status indicator lamp B, piece number: 15 is dimmed with break back contact 11.
embodiment 3:
the described elevator machinery range limiter with system reliable behavior indicator lamp, according to all types of mechanical service condition, ad hoc meter is directed to the range limiter of different machinery.Be designed with single status indicator lamp to single contact limiting device, reach the effect of state instruction, not only economize on resources but also can ensure that security of system actv. runs, principle is the same with double-contact range limiter.
