Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a limit ruler for warning bump marks. Background Art

[0002] Warning collision marks are used to indicate that when a locomotive is parked, it is not allowed to cross the direction of the switch or the intersection of the line, so as to prevent the locomotive and vehicle parked on the line from having a side collision with the locomotive and vehicle on the adjacent line. According to the measurement requirements of the rail warning collision mark, it is necessary to combine the center position of the rail and the location of the insulation joint for multiple measurements. The current method commonly used on the railway is to use a tape measure combined with manual judgment of the angle and multiple measurements. This measurement method causes a very large measurement error, and it is impossible to accurately find the angle perpendicular to the line. It is necessary to find a point two meters away from the center of the switch fixed and reverse lines many times. The angle error may cause the insulation pitch warning collision mark distance to be inaccurate, which may cause the actual limit insulation to not be included in the interlocking, thereby causing serious accidents such as side collisions of the train.

[0003] In the process of installing the warning bump sign, a warning bump sign limit ruler is needed. The Chinese utility model patent with the announcement number CN213974015U discloses a warning bump sign positioning ruler, including a first positioning part and a second positioning part. The first positioning part includes a first main body and a first clamping foot. The first clamping foot is fixed to the end of the first main body and is perpendicular to the first main body. The second positioning part includes a second main body and a second clamping foot. The second clamping foot is fixed to the end of the second main body and is perpendicular to the second main body. The first main body is rotatably connected to the second main body, and the connection point of the first main body and the second main body forms a positioning point. The utility model utilizes the rotation of the first positioning part and the second positioning part to make the first clamping foot and the second clamping foot fit the edges of the rails on the inner sides of the two lines respectively. The location of the positioning point is the location where the warning bump sign needs to be set.

[0004] However, during the use of the utility model warning mark positioning ruler, the position of the double-sided rails is not fixed, which makes it inconvenient to adjust the length of the measuring ruler according to the double-sided rails in different situations, which can easily lead to inaccurate installation of the warning mark, and multiple angle adjustments and multiple measurements are required during the measurement process, which seriously reduces the detection efficiency of the positioning ruler and cannot meet the use requirements. Therefore, a warning mark limit ruler is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a warning bump mark limit ruler, which has the advantages of easy measurement and strong practicality. It solves the problem that the existing warning bump mark positioning ruler is not fixed in position during use, making it inconvenient to adjust the length of the measuring ruler according to the double-sided rails in different situations, which easily leads to inaccurate installation of the warning bump mark, and the angle needs to be adjusted multiple times for multiple measurements during the measurement process, which seriously reduces the detection efficiency of the positioning ruler and cannot meet the use requirements.

[0006] To achieve the above object, the utility model provides the following technical solutions: a fouling mark gauge, which includes a rotating seat, a protractor fixedly installed on the front of the rotating seat, two measuring rulers rotatably connected inside the rotating seat, and two gravity hammers arranged outside the rotating seat. An expansion and contraction mechanism for expanding and contracting the gravity hammer and extending to the outside of the measuring ruler is arranged inside the measuring ruler, and an angle adjustment mechanism for adjusting the angles of the two measuring rulers and extending to the inside of the rotating seat is arranged outside the rotating seat;

[0007] The expansion and contraction mechanism includes an electric push rod fixedly installed inside the measuring ruler, a connecting rod fixedly connected to the output end of the electric push rod and extending to the outside of the measuring ruler, and a gravity hammer fixedly connected to the end of the connecting rod away from the electric push rod;

[0008] The angle adjustment mechanism includes a reduction motor fixedly installed outside the rotating seat, a rotating shaft fixedly connected to the output shaft of the reduction motor, a fixed seat rotatably connected to the outside of the rotating shaft, and a connecting seat fixedly connected to the outside of the rotating shaft.

[0009] Further, the number of the expansion and contraction mechanisms is two, and the two expansion and contraction mechanisms are staggeredly distributed inside the two measuring rulers.

[0010] Further, a sliding port adapted to the connecting rod is opened inside the measuring ruler, and the outer diameter of the connecting rod is adapted to the inner diameter of the sliding port.

[0011] Further, a slider extending to the inside of the measuring ruler is fixedly connected to the outside of the connecting rod, a sliding groove adapted to the slider is opened inside the measuring ruler, and the slider is slidably connected to the sliding groove.

[0012] Further, a mounting frame fixedly connected to the outer wall of the rotating seat is fixedly connected to the outside of the reduction motor, the rotating shaft is rotatably connected to the inside of the rotating seat, and a bearing adapted to the rotating shaft is fixedly installed inside the rotating seat.

[0013] Further, the fixed seat is fixedly connected to the outside of the top measuring ruler, the connecting seat is fixedly connected to the outside of the bottom measuring ruler, and a moving port adapted to the measuring ruler is opened inside the rotating seat.

[0014] Further, the fixed seat is in an inverted C shape, the outer diameter of the connecting seat is adapted to the inner diameter of the fixed seat, and the connecting seat is rotatably connected to the inside of the fixed seat.

[0015] Compared with the prior art, the utility model provides a fouling mark gauge, which has the following beneficial effects:

[0016] 1. The warning mark limit ruler starts the extension and retraction of the electric push rod through the controller. The extension and retraction of the electric push rod drives the connecting rod to move left and right. The left and right movement of the connecting rod drives the gravity hammer to move left and right, which is convenient for measuring the center point of the bilateral rails at different positions, so that the measuring angle of the measuring ruler is perpendicular to the rail body, achieving the advantage of easy measurement.

[0017] 2. The warning mark limit ruler starts the reduction motor through the controller. The reduction motor drives the rotating shaft to rotate. The rotation of the rotating shaft drives the connecting seat and the measuring ruler at the bottom to rotate. Any angle can be measured as needed. The combination of the protractor, measuring ruler and angle adjustment mechanism reduces the system error caused by multiple manual measurements, effectively improves the measurement efficiency, and achieves the advantage of strong practicality.
