Description

Technical Field

[0001] The invention relates to the technical field of track maintenance, and in particular to a fixing device and a detection method for a two-horizontal-one-vertical system. Background Art

[0002] Before the track replacement operation, it is necessary to ensure that the "two horizontal and one vertical" hook wires are well set up. This includes installation by the engineering department and confirmation by the electrical department to ensure that the traction return flow of the track circuit is unobstructed. Specifically, "two horizontal and one vertical" refers to two horizontal and one vertical connecting wires, which are used to connect the various parts of the track circuit to ensure the smooth conduction and return flow of current, thereby maintaining the normal operation of the signal equipment.

[0003] During the rail replacement process, the rail replacement section is first inspected to confirm that there is no signal equipment that interferes with the rail replacement work before the rail replacement operation can begin. Before cutting the rails, the engineering department manually checks whether the "two horizontal and one vertical" connection is in good condition. Only after confirming that it is correct can the rails be cut and replaced.

[0004] In the existing technology, there is often a poor connection or even a circuit break between the "two horizontal and one vertical" connecting lines and the rails, which results in the traction current not being able to be smoothly conducted and refluxed, causing the signal equipment to burn out and even causing accidental personal injury, seriously affecting the safety of construction workers. Summary of the invention

[0005] In order to solve the problems in the background technology, the purpose of the present invention is to provide a fixing device and a detection method for a two-horizontal and one-vertical system, which can monitor the connection status between the connecting wire and the rail in real time for use by the engineering department in decision-making.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The present invention provides a fixing device of a two-horizontal-one-vertical system, comprising a fixture seat, wherein the upper end surface of the fixture seat is provided with a groove; a pressure measuring block having a flat top surface and an inclined bottom surface is installed in the groove, wherein the top surface of the pressure measuring block is provided with an installation groove, and a pressure sensor is arranged in the installation groove;

[0008] The groove is also provided with an adjustment block with a flat bottom surface and a top surface matched with an inclined surface, and the adjustment block is arranged below the pressure measuring block; the end of the adjustment block is provided with a threaded hole; the side wall of the clamp seat is provided with a through hole matched with the threaded hole; the bolt passes through the through hole and is connected with the threaded hole, which is used to drive the adjustment block so that the pressure measuring block rises in the vertical direction.

[0009] As a further improvement of the above technical solution, the groove is a cavity with a narrow top and a wide bottom. The top cavity is adapted to the pressure measuring block so that the pressure measuring block is displaced in the vertical direction; the bottom cavity is adapted to the adjustment block so that the adjustment block is displaced in the horizontal direction.

[0010] As a further improvement of the above technical solution, the through hole is provided with an internal thread, and the internal thread is adapted to the external thread of the bolt.

[0011] As a further improvement of the above technical solution, the pressure sensor is connected to the bottom surface of the rail.

[0012] As a further improvement of the above technical solution, one end of the clamp seat is provided with a first slot to clamp the bottom surface of the rail, the other end of the clamp seat is located on the bottom surface of the rail, and the end is provided with a connecting rod, which is connected and fixed to the second slot through a wiring terminal.

[0013] As a further improvement of the above technical solution, the wiring terminal is a nut, and a number of nuts are provided.

[0014] As a further improvement of the above technical solution, the top surface height of the pressure sensor is slightly greater than the top surface height of the pressure measuring block.

[0015] The present invention also provides a detection method for a two-horizontal-one-vertical system, comprising:

[0016] S1. The plurality of fixing devices are arranged at the bottom of the rail, two transverse connecting lines are connected first, and then a longitudinal connecting line is connected, and the connection between the clamp seat and the rail is monitored in real time by a pressure sensor;

[0017] S2. Install resistance sensors and current sensors on the connecting lines to monitor the changes of resistance and current in real time;

[0018] S3. After the engineering department confirms that the connection is good, the track replacement operation is carried out;

[0019] S4. After the track replacement operation is completed, check whether all indicators meet the standards and remove the two horizontal and one vertical connecting lines.

[0020] In a specific implementation, in step S1, the bottom of the rail is firstly ground, and then the fixing device is arranged on the bottom of the rail.

[0021] In a specific implementation, in step S3, the conditions for a good connection between the clamp seat and the rail are: pressure ≥ 30 KN, current < 500 mA, and resistance < 1 ohm.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] By installing a pressure sensor in the mounting groove of the pressure measuring block and connecting the pressure sensor to the bottom surface of the rail, the pressure data generated by the interaction between the fixture seat and the rail can be directly and accurately obtained. The coordination between the adjustment block and the pressure measuring block and the design of driving the adjustment block by bolts to make the pressure measuring block rise in the vertical direction are ingenious. According to the actual installation requirements and the specific conditions of the rail, the height position of the pressure measuring block can be flexibly adjusted to ensure that the pressure sensor can be in a suitable measurement state, making the pressure measurement more in line with the actual working conditions, and to a certain extent, it can compensate for the installation differences caused by factors such as the uneven surface of the rail, ensuring the accuracy and reliability of the pressure measurement.

[0024] The groove on the upper end face of the fixture seat adopts a cavity structure with a narrow top and a wide bottom, which is adapted to the displacement requirements of the pressure measuring block and the adjustment block respectively. The top limits the vertical displacement of the pressure measuring block, making its movement trajectory clear and stable without random shaking or offset; the bottom ensures that the adjustment block can move in the horizontal direction, making the adjustment process smoother and the overall structure more tightly coordinated and reasonable, thereby enhancing the stability of the entire fixture during installation and use.

[0025] In the entire detection method, the pressure sensor is first used to monitor the connection between the fixture seat and the rail in real time, and the resistance sensor and current sensor are installed on the connection line to monitor the changes in resistance and current in real time. Through data collection and analysis in these three dimensions, the connection status of the entire two horizontal and one vertical system can be fully and carefully grasped from multiple perspectives such as mechanics and electricity.

[0034] A number of embodiments are given below to describe the present invention in detail.

[0035] Example 1

[0036] like Figures 1 to 4 As shown, a fixing device of a two-horizontal and one-vertical system comprises a fixture seat 1, wherein the upper end surface of the fixture seat 1 is provided with a groove 2; a pressure measuring block 3 having a flat top surface and an inclined bottom surface 31 is installed in the groove 2, and a mounting groove 32 is provided on the top surface of the pressure measuring block 3, and a pressure sensor 4 is arranged in the mounting groove 32;

[0038] Specifically, the groove 2 is a cavity with a narrow top and a wide bottom. The top cavity is adapted to the pressure measuring block 3 so that the pressure measuring block 3 is displaced in the vertical direction; the bottom cavity is adapted to the adjustment block 5 so that the adjustment block 5 is displaced in the horizontal direction.

[0039] Specifically, the adjustment block 5 is wedge-shaped and made of iron stainless steel.

[0040] Specifically, the through hole 11 is provided with an internal thread, and the internal thread is adapted to the external thread of the bolt 6 .

[0043] Specifically, the wiring terminal 9 is a nut, and the number of nuts is several. More specifically, washers are provided between adjacent nuts to facilitate the installation of the connecting wire.

[0044] Specifically, the top surface height of the pressure sensor 4 is slightly greater than the top surface height of the pressure measuring block 3, which is beneficial for the pressure sensor to be in a suitable measurement state and ensure the accuracy and reliability of pressure measurement.

[0046] The present invention also provides a detection method for a two-horizontal-one-vertical system, comprising:

[0047] S1. The plurality of fixing devices are arranged at the bottom of the rail, two transverse connecting lines are connected first, and then a longitudinal connecting line is connected, and the connection between the clamp seat and the rail is monitored in real time by a pressure sensor;
