Abstract
The utility model discloses a safety hook disc spring decrement automatic measuring device solves that current safety hook disc spring decrement measurement accuracy is not high, inefficiency, the problem of easily makeing mistakes. The utility model discloses a set up the support on the safety hook to and the compression nut that sets up on the safety hook extends the piece, the compression nut extends the compression nut of piece and safety hook and fixes continuously, go back the fixedly connected with displacement sensor support on the support, be fixed with displacement sensor on the displacement sensor support, displacement sensor links to each other through measuring the line with the top that the compression nut extends the piece, should measure the setting of line level. The utility model discloses application method and simple is difficult for makeing mistakes moreover, and measurement accuracy is also very high.
Description
Technical field
The utility model relates to a kind of safety catcher butterfly spring decrement self-operated measuring unit.
Background technology
Existing measurement safety catcher butterfly spring decrement relies on safety catcher after braking, and the angle rotated by safety catcher, carries out manual measurement after converting displacement to.When manually measuring, because the error of the measurer measuring people and use can affect the precision of measurement and the efficiency of detection.Measuring accuracy directly affects the calculating of the braking distance of safety catcher, and braking distance is the important indicator judging that whether anti-falling safety device is qualified.
Utility model content
The purpose of this utility model is to provide a kind of safety catcher butterfly spring decrement self-operated measuring unit, solves that existing safety catcher butterfly spring decrement measuring accuracy is not high, the problem of low, the easy erroneous judgement of testing table detection efficiency.Simultaneously this device solves from measuring principle the cumulative errors that relative displacement manual measurement brings.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Safety catcher butterfly spring decrement self-operated measuring unit, comprises the support be arranged on safety catcher, and is arranged at the compression nut extension block on safety catcher; The compression nut of described compression nut extension block and safety catcher is fixedly linked; Described support is also fixedly connected with displacement sensor bracket; Described displacement sensor bracket is fixed with displacement transducer; Institute's displacement sensors is connected by slotted line with compression nut extension block, and this slotted line is horizontally disposed with.Wherein, displacement sensor bracket is L-type structure.
Further, described displacement sensor bracket is also provided with the calibration display screen be connected with displacement transducer.
Again further, described slotted line one end end winding support is on compression nut extension block, and the other end is then positioned at displacement transducer.
The utility model compared with prior art, has the following advantages and beneficial effect:
The utility model adopts and directly measurement point two ends is fixed on above the support of safety catcher and the compression nut of safety catcher, so no matter safety catcher has great vibrations and springback capacity in measuring process, all measuring accuracy can not be had influence on, because the decrement of butterfly spring is controlled by compression nut, and the support of safety catcher is changeless, so the relative position change at measurement point two ends is exactly safety catcher butterfly spring decrement, this kind measuring method is simple, directly perceived, efficiency is high, and not easily make mistakes, and measuring accuracy is very high.
This device is adopted to substantially increase the efficiency of whole testing table and the accuracy class of testing table.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, mark corresponding parts name in accompanying drawing to be called: 1-safety catcher, 2-support, 3-compression nut extension block, 4-displacement sensor bracket, 5-displacement transducer, 6-slotted line, 7-display screen.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, safety catcher butterfly spring decrement self-operated measuring unit, comprises the support 2 be arranged on safety catcher 1, and is arranged at the compression nut extension block 3 on safety catcher 1; Described compression nut extension block 3 is fixedly linked with the compression nut of safety catcher 1; Described support 2 is also fixedly connected with displacement sensor bracket 4; Described displacement sensor bracket 4 is fixed with displacement transducer 5; Institute's displacement sensors 5 is connected by slotted line 6 with the top of compression nut extension block 3, and this slotted line 6 is horizontally disposed with.Wherein, support is fixedly connected on safety catcher, and displacement sensor bracket is fixedly connected on support, and be positioned at the top of safety catcher; So just make displacement sensor bracket static relative to safety catcher, and can not be moved, thus the displacement transducer making to be arranged on displacement sensor bracket also safety catcher is static relatively.But compression nut extension block then can be subjected to displacement along with the relative safety catcher of compression nut.The distance be arranged between compression nut extension block and displacement transducer is so just made to change, and this variable quantity safety catcher butterfly spring decrement just.
Conveniently observe, understand the decrement of safety catcher butterfly spring, described displacement sensor bracket 4 is also provided with the display screen 7 be connected with displacement transducer 5.The decrement of safety catcher butterfly spring can be got information about by display screen.
In addition, described slotted line 6 one end end winding support is on compression nut extension block 3, and the other end is then positioned at displacement transducer 5.In actual test process, because compression nut extension block moves with along with compression nut, so just the distance between compression nut extension block and displacement transducer is changed, thus the length of this section of slotted line between compression nut extension block and displacement transducer is changed, at this moment displacement transducer just can sense slotted line length now at once, thus sends data to display screen and show.
The utility model process of the test is as follows:
When safety catcher is braked, compression nut (right side namely in Fig. 1) inside safety catcher can be made mobile, drive compression nut extension block also toward safety catcher medial movement, but the support on safety catcher does not move, and the displacement sensor bracket be fixed on support does not also move, displacement transducer is fixed on displacement sensor bracket, so also do not move; Now, because slotted line one end is connected with compression nut extension block, when compression nut extension block is after safety catcher medial movement, the relative position of itself and displacement transducer changes, the slotted line be positioned between the two also just shortens, and this displacement transducer then can transfer to display screen the change in location data of induction, then shows, the numerical value shown, this time tests the decrement of the safety catcher butterfly spring recorded exactly.What deserves to be explained is, what the present embodiment adopted is SAJ type anti-falling safety device object as an example.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on said structure design; for solving same technical matters; even if some making on the utility model are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
