Abstract

The utility model relates to an elevator safe nipper spring detecting instrument. The utility model is characterized in that a mechanical device is arranged on an operation table through a base seat, and an oil tank which is connectedly provided with an oil pump electrical machine on the upper part is arranged below the operation table, and furthermore, an electrical equipment control cabinet composed of an air switch, a relay and a programmable controller is arranged in the operation table. The utility model not only can detect maximum elastic force value generated when a spring brings about maximum elastic deformation, but also can carry out the continuous and automatic detection of a rigidity changing condition during the deformation process of the utility model. Therefore, to judge whether safety nippers can work normally, the utility model can provide main bases. The utility model has the advantages of reliable performance and high automation level.

Description

Elevator safety gear laminated spring detector

The utility model relates to a kind of elevator safety gear laminated spring detector.

Safety tongs in the elevator is the important safety parts that guarantee lift running safety, in the safety tongs quality of the performance of laminated spring be directly connected to safety tongs can operate as normal.Use the checkout equipment of laminated spring in the known technology, the maximum flexibility power value that can only check-out console spring generation maximum flexibility be produced during distortion, can not carry out the continuous detecting of stiffness variation situation in its deformation process, and exactly in the laminated spring deformation process variation of rigidity be the main foundation of judging that can safety tongs operate as normal.In addition, the testing process of known checkout equipment and final whether qualified judgement also need manually be carried out, and therefore not only performance is backward for known checkout equipment, and also exists certain hidden danger when operation.

The purpose of this utility model is to overcome the deficiency in the known technology and provides a kind of to the automatic continuous detecting of laminated spring stiffness variation situation energy and detection dependable performance and the high elevator safety gear laminated spring detector of automaticity.

The purpose of this utility model is achieved in that

On operator's console of the present utility model, mechanical hook-up is housed, under its operator's console fuel tank is installed, on fuel tank, connect the loading pump motor, the electric control cabinet that is made of air switch, relay, Programmable Logic Controller also is housed in operator's console by base.

The concrete formation of above-mentioned mechanical hook-up is, symmetry is installed guidepost at the two ends of base, detect pressing head seat by two guidepost suits, on the detection pressing head seat, pressure transducer is housed, at the upper end of pressure transducer installation and measuring pressure head, by pressure transducer hydraulic jack is housed also on base, upper end by two guideposts also is set with crane span structure, displacement transducer and safety guard successively are housed on crane span structure, crane span structure the back install and to move back the workpiece device, in the position near tested workpiece one end of placing on it of crane span structure the anti-straight pin of adorning anti-tested workpiece is housed.

Above-mentioned crane span structure the concrete structure move back the workpiece device is installed is that the back of crane span structure installs two bearings, on the bearing of one back-moving spring is housed, and by two bearings handles is installed in the back.

The utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of mechanical hook-up among Fig. 1;

Fig. 3 is the side view of Fig. 2.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

With reference to Fig. 1, base 17 is installed on the operator's console 3, mechanical hook-up 4 is housed on base.The concrete formation of mechanical hook-up is, with reference to Fig. 2 and Fig. 3, symmetry is installed guidepost 10 at the two ends of base 17, on two guideposts, be set with and detect pressing head seat 16, pressure transducer 9 is contained on the detection pressing head seat, the installation and measuring pressure head 15 also in the upper end of pressure transducer, by pressure transducer hydraulic jack 8 is housed also on base, upper end by two guideposts also is set with crane span structure 11, displacement transducer 19 and safety guard 13 successively are housed on crane span structure, on crane span structure, have and detect hole 25, detect and place tested workpiece 12 in the hole, can take out more easily in order to make tested workpiece, therefore crane span structure the back also be equipped with and move back workpiece device 18, it is to install two bearings 20 by the back at crane span structure, 22, dress also is equipped with back-moving spring 21 on bearing 20, by two bearings handle 23 is installed and is constituted.Near being shaped on the anti-anti-straight pin 14 of adorning on the position of tested workpiece one end, it can prevent effectively that tested workpiece dress is anti-at crane span structure.Connect the above-mentioned fuel tank 1 that is equipped with under operator's console, also connect dress with Oil pump electrical machinery 2 on the fuel tank, electric control cabinet 24 also is housed in operator's console, it is made of parts such as air switch 5 and relay 6 and Programmable Logic Controllers 7.

Operating principle of the present utility model is, energized, make Oil pump electrical machinery 2 work by computing machine (not shown) and Programmable Logic Controller 7 and relay 6, Oil pump electrical machinery drives hydraulic jack 8 actions, drive mechanical hook-up 4 actions simultaneously, by detecting 15 pairs of tested workpiece 12 of pressure head, be that laminated spring pressurization in the elevator safety gear makes it to produce distortion, change by pressure transducer 9 detected pressures, measure the deflection of tested workpiece simultaneously by displacement transducer 19, tested workpiece reinforcing and displacement are drawn data through after the Computer Processing, compare according to the standard value that presets in advance in data that draw and the computing machine, judge whether tested workpiece is qualified.

Advantage and the good effect that the utlity model has are to use the utility model to examine The maximum flexibility power value that produces during the distortion of drafting board spring generation maximum flexibility can be carried out its distortion again The continuous automatic inspection of stiffness variation situation in the process, therefore for can the judgement safety tongs work, It can provide Main Basis. Moreover the utility model operating process is simple, and handling safety, Have the high characteristics of dependable performance and automaticity.
