Abstract
The utility model relates to a top suspending shaft pin force metering over loading alarm lift, which is composed of a lifting cage, a transmission mechanism, etc. The utility model is characterized in that two shaft pin type force cells are arranged between the lifting cage and the top arranging transmission mechanism and are used as the pin shafts for connecting lifting plugs, a strain gauge piece on the elastic body of each shaft pin type force cell is connected with a measuring circuit arranged in the lifting cage, and the measuring circuit is connected with a digital display meter, an alarm buzzer, and the control circuit of the top arranging transmission mechanism. The utility model has the advantages that the rated load of the lifting cage can be controlled and can be used furthest, and the accident cause by the overload operation of the lift can be effectively avoided. The utility model is suitable for the gear and the gear rack building lifts.
Description
The utility model belongs to the construction elevation and subsidence mechanical, particularly a kind of building hoist of gear rack transmission.
At present, general gear rack type construction lift, equal overloading free warning device, ubiquity the situation of estimation load and random overload operation in the use.The result of overload operation makes equipment accelerated wear test, and can cause the accident that jeopardizes equipment and personal safety at any time.A kind of elevator cab load-bearing and weighing means are arranged, form by leaf spring, contact, mounting plate, be to use leaf spring to replace the elevator cab load-bearing and the weighing means of original load-bearing sedan-chair bottom bracket, pull bar and weighing means, saved structural members such as sedan-chair bottom bracket, pull bar in the existing elevator.Though can realize weighing and overload warning, be not suitable on lift, using.
The purpose of this utility model is that the axial pin type load cell that adopts commodity is used to connect cage and up-set type driving mechanism as connecting bearing pin, by the weighing of cage carrying is measured, realizes the purpose to overload warning.
Of the present utility model going up hung pivot pin dynamometry overload warning formula lift, form by cage, driving mechanism, gear, tooth bar, guideway frame, driving mechanism is arranged on the cage top, it is characterized in that, between cage and up-set type driving mechanism, be provided with two axial pin type load cells as the bearing pin that connects hanger, straingauge on the axial pin type load cell elastomer measuring circuit interior with being arranged on cage is connected, and measuring circuit is connected with the control circuit of digital display meter, alarm buzzer, up-set type driving mechanism.
The using method that hangs pivot pin dynamometry overload warning formula lift that goes up of the present utility model is, when loading in the cage, the elastomer of axial pin type load cell produces resiliently deformable, the straingauge electrical quantity of bridge connection is changed, after the measuring circuit collecting treatment, by digital display meter instant playback cage carrying capacity numerical value.When cage overloads, report to the police by alarm buzzer and tutorial light, cut off up-set type transmission mechanism control circuit simultaneously automatically, make lift can not start operation.When cage did not overload, lift can normally start operation, and when starting operation, measuring circuit is cut off automatically, and overload alarm no longer works.
The advantage of suspension pivot pin dynamometry overload warning formula lift is on of the present utility model, can control the nominal load of cage reliably, guarantees safe operation; Can utilize the cage nominal load to greatest extent; Increase work efficiency; Can effectively avoid lift because the accident that overload operation causes; Can reduce wearing and tearing, prolong the working life of lift.Be applicable to gear, the tooth bar building hoist of the vertical personnel of transporting and material in various high-building constructions and the ascend operation.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 goes up the structure plan view that hangs pivot pin dynamometry overload warning formula lift
Fig. 2 goes up the side view that hangs pivot pin dynamometry overload warning formula lift
As seen from the figure, last suspension pivot pin dynamometry overload warning formula lift, form by cage, driving mechanism, gear, tooth bar, guideway frame, driving mechanism is arranged on the cage top, it is characterized in that, between cage 1 and up-set type driving mechanism 2, be provided with two axial pin type load cells 4 as the bearing pin that connects hanger 3, straingauge on the axial pin type load cell elastomer measuring circuit 5 interior with being arranged on cage is connected, and measuring circuit is connected with the control circuit 8 of digital display meter 6, alarm buzzer 7, up-set type driving mechanism.Among the figure, the 9th, gear, the 10th, tooth bar, the 11st, guideway frame, the 12nd, anti-falling safety device.
