Abstract
The utility model provides a device aiming to the problem having in the prior art, wherein, the device can test the residual voltage of a signal rail circuit, and the device can be used as a short-circuit line of a rail end. The attraction force generated by a magnetic steel (1) and a ferromagnetic fixing seat (3) of the device relative to a steel rail causes an electric conduction screw rod (5) to be appressed with the steel rail under the function of an elastic body (4). An outer shell (9) is fixed on the ferromagnetic fixing seat (3) by a connecting screw rod (10), and an adjusting handle (8) adjusts the pressure of the electric conduction screw rod (5) on the steel rail.

Description
The utility model belongs to the railway traffic safety device, particularly a kind ofly promptly can test signal track circuit residual voltage can be used as the device that rail terminal shortcircuit line uses again.
CN2463263Y provides a kind of magnetic adsorption type track circuit residual voltage testing standard shunt lead device in the prior art, wherein attached body of magnetic and rail rail level contact pressure are non-adjustable, the attached body of magnetic contacts with the rail rail level and is difficult to closely connectedly, makes attached body of this device magnetic and rail rail level contact resistance often greater than 0.06 Ω.This device to test value repeatability is very poor.Because this device and detecting of railway point contact resistance are big, can not use as rail terminal shortcircuit line.This device is not provided with corresponding test gear, signal track circuit residual voltage, short circuit current test inconvenience.
The purpose of this utility model is to provide a kind of at above-mentioned existing in prior technology problem promptly can test signal track circuit residual voltage can be used as the device that rail terminal shortcircuit line uses again, and the attractive force that the relative rail with ferromagnetic permanent seat (3) of this device magnet steel (1) produces makes conductive lever (5) be close to rail under the effect of elastic body (4).Shell (9) is fixed on the ferromagnetic permanent seat (3) by connecting screw rod (10), regulates the pressure of conductive lever (5) on rail by adjusting handle (8).Because conductive lever (5) and rail rail level contact pressure are adjustable, make this device contact with detecting of railway point reliably, the test value accurate science has good test repeatability.Because this device conductive lever (5) has been fixed the connecting strap (7) of connection signal track circuit test lead (2) by nut (6), changes suitable lead, can be used as rail terminal shortcircuit line.This device signal track circuit test lead (2) is provided with can test signal track circuit residual voltage, the isoparametric volt meter of short circuit current and amperemeter/ammtr.
This purpose realizes that with following technical proposal it mainly makes conductive lever (5) be close to rail under the effect of elastic body (4) by the attractive force that the relative rail with ferromagnetic permanent seat (3) of magnet steel (1) produces.Conductive lever (5) has been fixed the nut (6) of connection signal track circuit test lead (2) by nut (6).Shell (9) is fixed on the ferromagnetic permanent seat (3) by connecting screw rod (10), regulates the pressure of conductive lever (5) on rail by adjusting handle (8).
The design has been equipped with the conductive lever (5) that can regulate contact pressure, and the connection resistance after synchronous signal track circuit testing lead (2) passes through connecting strap (7) and conductive lever (5) is connected is minimum.So it solved prior art in test owing to the test point bad contact, be connected resistance and cause that test data is inaccurate, with a low credibility greatly, be difficult to correctly judge actual minute problem such as line state of track circuit.Contact resistance with track in test has been lower than 0.001 ' Ω.And the residual voltage value of measuring is the actual shunt residual voltage value under the shunt of 0.06 ' Ω standard shunt lead fully, and its data can reflect actual minute line state of signal track circuit fully.Change suitable lead in addition, can be used as rail terminal shortcircuit line, greatly facilitate maintenance activity.
Following accompanying drawing has provided embodiment of the present utility model:
