Abstract
The utility model relates to an anti-cable broken, load limiting safety device for an elevator apparatus, which is mainly composed of a hanging rod 3, a spring 5, a spring seat 6, a guide sleeve 7, a pressing board 8, levers 10 and 11, a travel switch 14, a push rod 15, a safety tong seat 16, etc. The utility model uses the elastic force of the spring 5 and a link gear to make a pair of safety tongs clamp a guideway 12 when a wire rope is broken due to the accident of a car, which realizes an anti-falling purpose. The utility model uses the push rod 15 and the travel switch 14 to switch off a power supply of a host machine and generates alarm signals when overloading happens. The utility model has the advantages of simple structure, low cost, easy installation, convenient maintenance, convenient adjustment, and safe and reliable action.
Description
The utility model relates to anti-fall, the limit for tonnage safety device of the disconnected rope of a kind of gig.
The safety guard that gig is commonly used mostly is and is installed in the velocity limiter in the machine room and the servo-actuated steel rope, transmission device, the safety tongs clamping mechanism that are attached thereto and is installed on the interior expansion tightening wheel of well pit etc. at present; this installs not only complex structure, manufacturing cost height; the Installation and Debugging trouble; and overload, Weighing mechanism complexity, influence its applying in gig.
The purpose of this utility model provides a kind of safety device that the disconnected rope of gig collection is anti-fall, two kinds of functions of limit for tonnage are one that is used for.Its not only simple in structure, low cost of manufacture, and Installation and Debugging, maintenance is easy, action is safe and reliable.
Disconnected rope provided by the utility model is anti-fall, the limit for tonnage safety device mainly is made up of suspension rod, spring, guide pin bushing, pressing plate, lever, waits the purpose of the security insurance that reaches gig by compression spring, link gear and safety tongs, travel switch.Spring perch is fixed in the bridge railway carriage or compartment upper beam center at the end, spring places spring perch, prevent that spring cross travel, inclination, guide pin bushing and spring perch from making one, one end of suspension rod is connected with haulage cable, the other end passes guide pin bushing, spring center and pressing plate center, and be fixed, suspension rod can be free to slide in guide pin bushing.Spring produces compression under the effect of deadweight of steel rope and bridge railway carriage or compartment and load, by pressing plate, and members such as pressing plate pivotally attached lever, shadoof.The inclined-plane voussoir is depressed, the getaway face, at this moment, gig is lifting freely.When steel rope disconnected for some reason, steel rope was to the pulling force vanishing of suspension rod.Pressing plate is down motion under the elastic force effect, by lever, shadoof the inclined-plane voussoir on both sides, bridge railway carriage or compartment is up mentioned along the safety gear block inclined-plane simultaneously, clamps guide pass, prevents the bridge railway carriage or compartment to fall; And if cut off host power supply bridge railway carriage or compartment flat-out acceleration in operational process simultaneously and glide, at this moment, steel rope is to the pulling force of the suspension rod elastic force less than spring itself, suspension rod is down flicked, by pressing plate, link mechanism voussoir is mentioned, clamp guide rail, prevent the tenesmus of bridge railway carriage or compartment continuation hypervelocity, reach purpose of safety.Load carrying ability when the bridge railway carriage or compartment surpasses the load carrying ability that is allowed, and then spring is by supercompression, and the push rod that is fixed on the pressing plate is up run into the travel switch contact that is fixed on the spring, cuts off host power supply, and sends warning signal, prevents that overload from causing the accident.
The utility model is through the real-world operation evidence; its action is safe and reliable; played anti-fall, the limit for tonnage protective effect of the disconnected rope of gig; be adapted at applying on the gig;, simple installation simple because of this apparatus structure, convenient, the low cost of manufacture of debugging are beneficial to this device the safety device that has gig now are transformed.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1-be the utility model structural representation.
The inclined-plane voussoir A of Fig. 2-be Fig. 1 is to lateral plan.
As shown in drawings, this device is installed on the center of upper beam 1 bottom in bridge railway carriage or compartment, spring perch 6 is fixing with upper beam, guide pin bushing 7 joins together with spring perch 6, spring 5 places seat, one end of suspension rod 3 is connected with steel rope 4, the other end passes guide pin bushing 7, spring 5 and pressing plate 8 centers, and it is fixing with double nut 9, the two ends of pressing plate link with lever 10,11 respectively, and two bearings 2 of lever are fixed in the end of putting the beams in place, and lever can be a spot wobble by bearing 2, travel switch 14 is fixed in by its support on the base plate of spring perch 6, and push rod 15 is fixed on the pressing plate 8.Spring 5 is compressed under the effect of steel rope 4 and deadweight of bridge railway carriage or compartment and load, pressing plate 8 up moves, and drives lever 10,11 and pressing plate pivotally attached one end and up moves, and the lever other end is depressed shadoof 13 and inclined-plane voussoir 18, getaway face 12, but make bridge railway carriage or compartment free lifting.Disconnect for some reason as steel rope 4, suspension rod 3 is down motion under the effect of elastic force, by pressing plate 8, lever 10,11 the inclined-plane voussoir 18 of both sides, bridge railway carriage or compartment is mentioned simultaneously, inclined-plane voussoir 18 clamps guide rail 12 along the inclined-plane of the pincers seat 16 that is fixed in bridge railway carriage or compartment underbeam 17, prevent the bridge railway carriage or compartment to fall, as car flat-out acceleration downslide for some reason in operational process, then the pulling force of 4 pairs of suspension rods 3 of steel rope is less than the elastic force of spring 5, pressing plate 8 is turned down, simultaneously the inclined-plane voussoir 18 of both sides, bridge railway carriage or compartment is mentioned, clamp guide rail, prevent the tenesmus of bridge railway carriage or compartment.If the overload of bridge railway carriage or compartment, spring 5 is made the contact of top line journey switch 14 on the push rod 15 by supercompression, cuts off the power supply of main frame, and sends the signal of alarm, prevents to have an accident because of overload.
