Description

 The invention relates to transport, namely to railway, and can be used to detect sagging objects while rolling stock.

 The closest in technical essence and the achieved economic effect is a device for determining the size of the rolling stock [see author St. USSR 1791237 "Device for determining the size of rolling stock", cl. B 61 K 9/02, publ. 01/30/93, BI 4], which contains a means of contact, overlapping the controlled space installed in a plane perpendicular to the track, and a control sensor connected to the measuring unit.

 The disadvantage of the device is its low reliability due to the presence of articulated joints of the control rods and roller contacts, which, in contact with a sagging or dragging object while the rolling stock is moving, can catch on it and at least disrupt the device itself and create an emergency situation as a maximum.

 The aim of the present invention is to increase reliability.

 This goal is achieved by the fact that the device for detecting sagging objects on the move of the rolling stock, comprising contact means overlapping the controlled space installed in a plane perpendicular to the rail track, and a control sensor connected to the measuring unit contains a vibration conduit and vibration isolators, by means of which the vibration conduit is mounted on the railroad tie and the contact means is made in the form of chippers installed along the vibrating conduit, made by gable, whose ramps are rigidly connected to the vibro a wire on which a control sensor is installed, made in the form of a vibration sensor.

 Such an embodiment, in which the device contains a vibroconductor and vibration isolators, by means of which the vibroconductor is mounted on the sleeper, and the contact means is made in the form of bumpers installed along the vibroconductor, slopes of which are rigidly connected to the vibroconductor, on which a control sensor made in the form of a vibration sensor is installed, provides increased reliability of the device by simplifying and at the same time tightening the design, which allows a sagging object after collision with a baffle plate oh pass it freely and creates the possibility of safe two-way passage of rolling stock over the device.

 Figure 1 shows a General view of the device; figure 2 is a top view of figure 1; figure 3 is a section aa in figure 1; figure 4 is a section bB in figure 1.

 The device for detecting sagging objects along the rolling stock contains a vibroconductor 1, which, by means of vibration isolators 2, is mounted on the railroad tie 3 under the rails 4. The chippers 5 are installed along the vibroconductor 1 between the rails 4 and on both sides of them. Both slopes 6 of each chipper 5 are rigidly connected through the brackets 7 to the vibroconductor 1. The control sensor 8, made in the form of a vibro sensor, is mounted on the vibroconductor 1 and connected to the measuring unit 9.

 The device operates as follows. In the absence of rolling stock, there are no vibrations of the vibroconductor 1, and the initial state is established at the output of the measuring unit 9. When the rolling stock passes over the device in the vibrating conduit 1, vibrations occur, which are converted by the vibration sensor 8 into an electrical signal and are recorded by the measuring unit 9. In this case, a text signal of the “serviceability” of the device is generated, which, firstly, indicates that the device is in working condition, and, secondly, it opens a key circuit (not shown) for the passage of the alarm signal. If a sagging object is detected under the rolling stock in the controlled area, it strikes at least one of the fenders 5. Vibrations from the shock are transmitted through the vibroconductor 1 to the vibration sensor 8 and converted into an electrical signal, which in the measuring unit 9 generates an alarm signal. The amplitude of the signal from the impact of a sagging object is N times greater than the amplitude of the vibration signal from the rolling stock (N ≈ 200). This is achieved by the fact that the chippers 5 are rigidly fixed to the vibroconductor 1, and that, in turn, through the vibration isolators 2 is fixed to the sleeper 3.

 The use of such a device allows timely detection of the presence of an extraneous sagging or dragging object in the controlled area under the lower dimension of the rolling stock and to prevent its collapse.
