Description

Technical Field

[0001] The utility model relates to the technical field of rail transit vehicle detection, in particular to a rail vehicle lower limit detection device. Background Art

[0002] Vehicle limits are the outline dimensions that cannot be exceeded during the design and manufacture of rail vehicles. The regulations on vehicle limits ensure the safe operation of vehicles on railway lines and prevent them from colliding with buildings and equipment on adjacent lines. Therefore, new and repaired rail vehicles must pass the measurement and verification of limits before leaving the factory to meet relevant standards.

[0003] Most of the current vehicle clearance detection equipment are clearance gates, which occupy a large space and are difficult to move. In addition, there is currently a magnetic rail vehicle lower clearance detection device, which is characterized by comprising: a positioning member, the positioning member includes a steel plate and a steel bar, and the steel plate is fixed to the ground through the steel bar; a magnetic base, which is arranged above the positioning member and magnetically connected to the positioning member; a reset member, the reset member includes a reset plate and a reset elastic member, the reset plate is connected to the magnetic base through an axis and can rotate around the axis, and a pair of reset elastic members are sleeved at both ends of the axis, one end of each reset elastic member is fixedly connected to the reset plate, and the other end of each reset elastic member is fixedly connected to the magnetic base; a detection member, the detection member is connected to the reset plate through a connecting member. The detection device needs to be fixed on the ground.

[0004] Therefore, the clearance gates and public detection devices are all installed after the construction is completed, and then the vehicle is shunted to the relevant position for clearance detection. If an over-limit problem is found, especially in the lower part of the vehicle, due to the installation of more equipment, the completed vehicle needs to be re-shunted to the construction platform, and then the relevant over-limit position needs to be reworked, which is difficult to construct and wastes a lot of costs. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present utility model is to solve the above-mentioned deficiencies in the prior art, thereby proposing a rail vehicle lower limit detection device that can complete the detection and verification of the vehicle lower limit when the rail vehicle is partially completed, without the need for shunting, and is portable and easy to operate.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is a rail vehicle lower limit detection device, including a lower limit gauge, an angle limit gauge and a side limit gauge;

[0007] A positioning boss is protruded from the middle of the lower end of the lower limit gauge, and the width H1 of the positioning boss is consistent with the distance between the inner sides of the two rails on the track line; stable blades for supporting positioning are vertically arranged on the front and rear surfaces of both ends of the lower limit gauge, and the spacing H2 between the stable blades on both sides is greater than the distance between the inner sides of the two rails on the track line, and less than the distance between the outer sides of the two rails on the track line;

[0008] There are two angular limit gauges, which are symmetrically arranged at both ends of the lower limit gauge;

[0009] There are two side limit gauges, and the two side limit gauges are respectively arranged at the upper ends of the two angle limit gauges.

[0010] The distance H3 between the inner sides of the two side gauges is the maximum width allowed on both sides of the rail vehicle.

[0011] The lower limit gauge, the two corner limit gauges and the two side limit gauges are integrally formed.

[0012] The lower limit gauge and the two corner limit gauges are provided with weight-reducing holes.

[0013] Support blades are vertically arranged on the front and rear sides of the middle part of the lower limit gauge.

[0014] The lower end surface of the supporting blade is flush with the lower end surface of the positioning boss.

[0015] The beneficial effects of the utility model are:

[0016] 1. The utility model provides weight-reducing holes in the lower limit gauge and the angle limit gauge to reduce the overall weight of the device, and the weight-reducing holes can also serve as handrails to improve the portability of the device.

[0017] 2. The positioning boss fixed on the lower limit gauge of the utility model can clamp the device on the inner edge of the rails on both sides during detection without additional positioning operation. When not in use, the support blade serves as a stabilizing device to place the detection device stably on the ground without tipping over. The operation is simple and practical.

[0018] 3. The stabilizing blade fixed on the lower limit gauge of the utility model can stand on the upper surface of the rails on both sides during detection, so that the detection device will not fall over during detection, thereby ensuring the detection accuracy.

[0023] See also Figure 1~2 In an embodiment of the utility model, a lower limit detection device for a rail vehicle includes a lower limit gauge 1, and symmetrical left and right angle limit gauges 2 and 3 are provided on both sides of the lower limit gauge 1. Symmetric left and right limit gauges 4 and 5 are provided on the outer sides of the upper end surfaces of the left and right angle limit gauges 2 and 3, and the distance H3 between the inner sides of the left and right limit gauges 4 and 5 is the maximum width allowed on both sides of the rail vehicle. The lower limit gauge 1, the left angle limit gauge 2, the right angle limit gauge 3, the left limit gauge 4 and the right limit gauge 5 are welded into one body. Stabilizing blades 7 for supporting and positioning are vertically arranged on the front and rear surfaces of both ends of the lower limit gauge 1, and supporting blades 9 are vertically arranged on the front and rear surfaces of the middle part of the lower limit gauge 1. The spacing H2 between the stabilizing blades 7 on both sides is greater than the distance between the inner sides of the two rails on the track line, and less than the distance between the outer sides of the two rails on the track line; a positioning boss 6 is protruded from the middle of the lower end of the lower limit gauge 1, and the width H1 of the positioning boss 6 is consistent with the distance between the inner sides of the two rails on the track line; the lower end surface of the supporting blade 9 is flush with the lower end surface of the positioning boss. The lower limit gauge 1 and the two corner limit gauges are provided with weight-reducing holes 8, which also serve as handrails for easy grasping.

[0024] The steps for using this measuring device are as follows:

[0025] 1. Place the device on the rail at the lower limit of the rail vehicle to be measured.

[0026] 2. Make the positioning boss 6 close to the inner edges of the rails on both sides for positioning.

[0027] 3. Make the stabilizing blades 7 on both sides vertically and closely adhere to the upper surfaces of the rails on both sides to form support.

[0028] 4. Carry out limit measurement. If there is interference between the vehicle equipment and the measuring device at that position, it indicates an over-limit problem.

[0029] From the above steps, it can be seen that the measurement device can be installed to determine whether the lower part of the vehicle at that location is over-limited. The operation is simple and fast, and the results are intuitive and clear. The technical proficiency of the measurement personnel is low, the measurement error is small, the results are reliable, and the work efficiency is greatly improved.
