Abstract
The utility model provides an elevator wire rope stress difference ergometer, which comprises a pothook, a force measuring sheet connected with the pothook, a paper characteristic foil gauge stuck on the force measuring sheet and a force measuring display circuit in electric connection with the paper characteristic foil gauge. The force measuring display circuit consists of power supply, test, storage, control, transfer and display parts in electric connection. The utility model is an advanced elevator wire rope stress difference ergometer with convenient reading and exact measuring.
Description
The utility model relates to the detection apparatus of the stressed difference of a kind of elevator traction wire rope.
Many wire rope of lift car traction steel-cable are in operation can produce the unbalanced situation of tension force, if great disparity is excessive, easily traction sheave is produced and destroys, accidents caused, therefore often will detect the stressed difference of wire rope.What the detection of steel wire rope tension was used is that spring balance adds ruler in the past, promptly hooks wire rope toward post-tensioning with spring balance, measures displacement with ruler then, can draw the Tension Difference between wire rope.This kind method deficiency be: the reading inconvenience, error is big because it is stressed bigger to certain position to pull wire rope, hand tremor is moving severe, just is difficult to reading with the displacement of the ruler amount of going, and inaccurate, error is big, this kind method can not satisfy the requirement of accurate detection.
The purpose of this utility model is to provide a kind of convenient reading, surveys the stressed poor dynamometer of elevator traction wire rope of number electronic liquid crystal demonstration accurately.
Can realize the purpose of this utility model by following proposal, the stressed poor dynamometer of a kind of elevator traction wire rope is characterized in that: the dynamometry sheet that it is connected with hook by hook, the display circuit that the papery foil gauge reaches and papery answers sheet to electrically connect that is attached on the dynamometry sheet constitute; The dynamometry display circuit is electrically connected by power supply, detection, storage, control, conversion, display part and constitutes, wherein the test section connects formation as the electric bridge of an arm with IC (F007) by the papery foil gauge, it connects with the storage area that LF (198) constitutes, control section is connected with travel switch and reset button by the relay with two groups of moving contacts and constitutes, it connects with storage area, storage area connects with the conversion portion that AD (571) constitutes, and conversion portion connects with the display part that ENDS (809A) constitutes.
For making dynamometer be convenient to operation, it also is provided with a shell, and the back side of shell is provided with the circle cover, shell is enclosed within on the slide bar by circle, be provided with an orientable slide block on slide bar, travel switch is located at the end of shell by slider end, and reset button, display window, power switch are located at the front of shell.
Effect of the present utility model is convenient reading, detects accurately, provide assurance for the safe handling of elevator.
Below in conjunction with accompanying drawing the utility model is further set forth.
Accompanying drawing 1 is synoptic diagram of the present utility model (broken section).
Accompanying drawing 2 is a circuit diagram of the present utility model.
Referring to accompanying drawing 1: the panel of shell 1 is provided with display window 2, reset button 3 and power switch 4.The back side of shell 1 is provided with the circle cover, and shell 1 is enclosed within on the slide bar 5 and can be free to slide by circle.Hook 6 connects with dynamometry sheet 7.Metal or the nonmetallic slices of dynamometry sheet 7 for having certain intensity.Papery foil gauge 8 is attached on the dynamometry sheet 7, and it and internal circuit electrically connect.Travel switch 9 is located at the bottom of shell 1.One slide block 10 is arranged in the bottom of slide bar 5, and slide block 10 can slide along slide bar 5, which is provided with orientable screw.
Referring to accompanying drawing 2: circuit is electrically connected by power supply, detection, storage, control, conversion, display part and constitutes, and wherein the electric bridge be made up of R1, R2, R and W1 of test section connects formation (for papery foil gauge 8) with IC (F007).The function of this part is that R changes under the effect of pulling force, thereby the level of the two ends input of IC (F007) is changed, and exports a high level with the R variation at the output terminal of IC (F007).The test section connects with the storage area that LF (198) constitutes, LF (198) receives from the electric signal of test section and stores, flow to simultaneously the conversion portion that is made of AD (571) again, AD (571) is digital signal with the defeated next analog-signal transitions of storage area and is defeated by the demonstration of ENDS (809A) display part.Control section is made of two groups of relay K that drive contact K1, K2 and travel switch 9 and reset button 3, and it connects with the input end of LF (198).Its function is when travel switch 9 during by slide block 10 touching, promptly sends control signal, and instruction LF (198) stops storage and freezes data on the AD (571), and data are fixed up on ENDS (809A); If will continue to measure, press reset button 3, control section sends control signal and it is reworked for LF (198) and AD (571).
Testing process of the present utility model is: with hook wire rope is hooked, slide bar is fixed with modes such as supports, slide block is fixed on the slide bar from shell a distance, holding shell pulls back, this process display window constantly shows the relay data, and when travel switch touching slide block, control parts of circuit is promptly sent an electric signal and given storage and conversion portion, make it stop to store and changing and pin last data, this data delivery shows to the display screen and is the data of surveying.Restart when detecting, press the ammonium button that resets and get final product, process is ditto described.
Claims (2)
1, the stressed poor dynamometer of a kind of elevator traction wire rope is characterized in that, links up with the dynamometry sheet that connects, is attached to the dynamometry display circuit that the papery foil gauge reaches and the papery foil gauge the electrically connects formation on the dynamometry sheet; The dynamometry display circuit is electrically connected by power supply, detection, storage, control, conversion, display part and constitutes, wherein the test section connects formation as the electric bridge of an arm with IC (F007) by the papery foil gauge, it connects with the storage area that LF (198) constitutes, control section is connected with travel switch and reset button by the relay with two groups of moving contacts and constitutes, it connects with storage area, storage area connects with the conversion portion that AD (571) constitutes, and conversion portion connects with the display part that ENDS (809A) constitutes.
