Abstract
A portable goat tester comprises a casing and a thrust transducer arranged in the casing. The output end of the thrust transducer is connected with a display device and the bottom of the casing is further provided with a magnetic component connected with the thrust transducer. Since the thrust transducer is fixed on the waist portion of a stock rail by the magnetic component when the utility model is being used, the engaging and separating movement of the connecting rod pin is saved, which greatly reduced the testing time and the whole testing course takes less than three minutes. Further, the transducer is arranged on the waist portion of the stock rail, thereby the problem that the change of the force direction to the transducer can result in the inexact testing result does not exist.
Description
Technical field
The utility model relates to a kind of railroad survey instrument, particularly a kind of Portable Test Instrument of Point Machine.
Prior art
Portable goat (track switch) tester must pull out turn-out track and make the bar connecting pin when test goat and track switch conversion power, replaces the conversion power of actuating strut connecting pin test goat with pin formula force transducer.Extracting of this connecting pin is very difficult, and its reason is: connecting pin is in the field, and the surrounding enviroment very severe, easily causes actuating strut connecting pin clamp nut to get rusty; Goat must be rotated and just connecting pin can be pulled up; The connecting pin clamp nut is in the actuating strut below, and is overhead very near, and fastening or loosening this nut all is difficult to operation.The insertion of same pin formula force transducer also is very difficult, and the actual loading direction of pin formula force transducer and demarcation are subjected to force direction to be difficult to guarantee, can cause varying in size of test result and actual forces, this mode test duration oversizely needs 10-20 minute in sum, and test result is inaccurate, the railway system considers safety and production efficiency in addition, and one group of track switch application test duration generally is difficult to above 5 minutes.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and providing a kind of can shorten the test duration, improves operating efficiency, improves measuring accuracy, guarantees the Portable Test Instrument of Point Machine of site work personal security.
For achieving the above object, the technical solution adopted in the utility model is: comprise housing and be arranged on the interior force transducer of housing, be characterized in that the output terminal of said force transducer is connected with display device, and also be provided with the magnetic part that is connected with force transducer in the bottom of housing.
Another characteristics of the present utility model are: magnetic part is a magnet; Display device is pointer indicator gauge or digital display meter.
Because the utility model is fixed on force transducer by magnetic part the waist portion of stock rail in use, without Plug Action bar connecting pin, greatly reduce the test duration, whole test process is no more than 3 minutes, and the waist portion that this sensor is installed on stock rail does not exist sensor to be subjected to force direction to change the inaccurate problem of test result that causes.
Description of drawings
Accompanying drawing is an one-piece construction synoptic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are described in further detail.
Referring to accompanying drawing, the utility model comprises housing 1 and is arranged on force transducer 2 in the housing 1 that the output terminal of force transducer 2 is connected with pointer indicator gauge or digital display meter 3, and also is provided with the magnet 4 that is connected with force transducer 2 in the bottom of housing 1.
In use the magnet by housing 1 bottom with the utility model be adsorbed in the tongue T-iron over against the waist place of stock rail 5, by goat work, switch with follow up movement moves, make point tongue extruding force sensor 2, accurately measure thereby track switch is changed power by pointer indicator gauge or digital display meter.
The utility model is without Plug Action bar connecting pin, and the fixed form of this cushion force transducer is easy, greatly reduces the test duration, and whole test process is no more than 3 minutes; This sensor does not exist sensor to be subjected to force direction to change the not accurate enough problem of test result that causes owing to be installed in the waist portion of stock rail.
