Description

Technical field:

[0001] The utility model relates to the field of track detection devices, in particular to a device for detecting the deformation of railway tracks. Background technology:

[0002] Under the weight of hundreds of tons of trains, the rails are prone to deformation during long-term use. Once the rails are severely deformed, it is easy to cause very serious safety accidents. During the inspection and maintenance of the railway, it is often necessary to detect the deformation of the distance between the rails. The traditional method generally uses a simple ruler to measure, or uses infrared distance measurement detection. These detection methods are too slow and cannot detect every point on the track.

[0003] The utility model patent with publication number CN110779434A records a railway track deformation quality detector, which includes a rail symmetrically fixedly installed on the bottom surface, a body is provided on the front side of the rail, and wheel grooves with openings facing backwards are symmetrically provided in the body, and a wheel axle is rotatably connected between the front and the rear in each wheel groove, and a sliding key is fixed on the wheel axle, and a wheel is symmetrically slidably connected between the sliding key and the wheel axle, and the wheel is slidably connected to the rail, and brackets are fixedly provided on the left and right sides of the body, and detection boxes are fixedly connected between the brackets on the left and the brackets on the right, respectively, and each detection box is provided with an adjustment cavity, and one of the adjustment cavities A lifting cavity is symmetrically arranged on the upper and lower sides of the side wall, and a measuring device for measuring the distance between the rails is arranged in the lifting cavity. The measuring device includes lifting blocks slidably installed in the lifting cavity for the vehicle up, down, left and right respectively, and a detection rod sliding with a side wall of the lifting cavity and a side of the detection box is fixed on one side of the lifting block, and a detection wheel is rotatably connected to one side surface of the detection rod, and an adjustment device for adjusting the distance between the detection wheels according to the track width of different countries and regions is arranged between the adjustment cavity and the machine body, a paint box is arranged in the machine body, and a paint tube is connected to the top wall of the paint box, and a recording device for recording railway damage points is arranged between the machine body and the detection box.

[0004] According to the above, the patent installs wheels on railway tracks, and then drives the rails to move quickly. The distance the detection wheel moves is used to detect whether the rails are damaged or bent. Then, during the detection, paint is sprayed onto the rails for recording. However, the patent can only detect deformation on the inner side of the rails. If there is a bulge on the outer side of the rails and a depression on the inner side, the detection wheel of the patent cannot move for detection and spray marking, so that the deformed parts of the rails cannot be fully detected, and the detection is not comprehensive.

[0005] Therefore, there is a need for a detection device that can detect both the inside and outside of the rail. Summary of the invention:

[0006] The technical problem to be solved by the utility model is to provide a railway track deformation detection device, which can detect the inside and outside of the railway track, so that each deformation point of the railway track can be detected, and the position can be automatically marked after the deformation point of the railway track is detected, thereby improving the detection effect.

When the extrusion column moves in the injection tube, it drives the extension strip to move in the sliding mouth of the injection tube. The extension strip can prevent the spray liquid in the injection tube from leaking out of the sliding mouth. A slider is slidably provided in each sliding mouth to press against the outer end of the extrusion column. A notch is also provided at the position of the extrusion column corresponding to each slider for the slider to be aligned and abutted with the extrusion column.

After the extrusion column contacts the touch pressure switch, the electric control valve is controlled to be closed, and the spraying liquid in the injection tube is filled.

[0041] Working process:

[0042] When the deformation of the two steel materials formed by the railway track is detected, the rail car moves along the railway track. During the movement of the rail car, the two detection mechanisms respectively detect the deformation of the inner and outer sides of the steel materials. During the detection process, the rail car moves along the railway track, and the two track wheels of the two detection mechanisms also move along the edge of the steel materials. The first track wheel contacts the outer side surface of the steel material, and the second track wheel contacts the inner side surface of the steel material. The first track wheel and the second track wheel are approached to each other through the elastic pressure component, which causes the steel material to be clamped between the first track wheel and the second track wheel. Under the action of the elastic pressure component, the first track wheel and the second track wheel can move along the edge of the steel material. When the first track wheel and the second track wheel pass through the deformed raised part, since the anti-slip disks of the first track wheel and the second track wheel are connected to the corresponding extrusion columns through a linkage, the movement of the first track wheel or the second track wheel causes the anti-slip disk to drive the connecting rod to move, and the connecting rod movement drives the extension plate of the slider to move along the sliding mouth of the injection tube, thereby driving the extrusion column to move in the injection tube. The slider and the extrusion column are not connected, but because the injection tube is filled with spraying liquid, the extrusion column is in contact with the slider. When the slider pushes the extrusion column to move deep in the injection tube, the injection tube is filled with spraying liquid through the liquid inlet. When the spraying liquid is injected into the injection tube, the extrusion column is pressed in contact with the touch switch. When the touch switch is triggered, the injection of the spraying liquid is stopped to ensure the normal spraying of the spraying liquid. After the extrusion column squeezes the spraying liquid, the spraying liquid is squeezed out along the nozzle through the liquid outlet, and then sprayed on the upper surface of the steel at the deformation point, which is convenient for the staff to repair or replace the deformation point of the railway track.

[0043] Since the pressure sensor is connected together with the elastic pressure component, after the elastic pressure component is deformed, the pressure sensor will feel the pressure brought by the elastic pressure component, thereby knowing that there is a deformation point at the position of the steel. The signal is transmitted to the staff through the degree of pressure applied to the pressure sensor to know the degree of deformation of the deformation point.

[0044] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
