Description

Technical Field

[0001] The utility model relates to the field of measuring equipment, in particular to a portable measuring model ruler for a monorail hanging track. Background Art

[0002] In order to meet the objective requirements of the development of auxiliary transportation in coal mines, in the process of coal mine production, the monorail crane transportation system is used to replace the ground rail transportation system for underground transportation of materials, personnel and equipment in coal mines. The monorail crane consists of a suspended monorail track and a locomotive in the tunnel, and the laying quality of the monorail crane track is directly related to the safe operation of the auxiliary transportation system in coal mines.

[0003] Since the suspension of the coal mine monorail track is arranged at high altitude, the measurement of whether the track status during its installation and daily operation is qualified is basically in the state of visual inspection and height measurement. The measurement not only requires multiple people to work together at height, which poses a great safety hazard, but also cannot accurately obtain the measurement results, and thus cannot determine whether the monorail crane transportation system has the conditions for safe operation, making the assessment of the track laying quality complicated and inefficient, with a high risk factor. Utility Model Content

[0004] The utility model provides a portable measuring model ruler for a monorail crane track, aiming to accurately measure key parameters of a coal mine monorail crane track and improve the measurement efficiency and the accuracy of the measurement result.

[0005] To achieve its purpose, the utility model adopts the following technical solutions:

[0007] Preferably, the rail joint left-right deviation measuring portion and the rail joint height deviation measuring portion are both notches on the edge of the measuring ruler.

[0008] Preferably, the measuring rod is telescopic.

[0009] Preferably, the outer wall of the handle is covered with a rubber sleeve.

[0010] Preferably, the thickness of the measuring ruler is the same as the distance of the rail joint gap.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The measuring model ruler provided by the utility model is specially designed for the measurement needs of the laying quality of coal mine monorail hanging tracks. The model ruler is made of high-carbon steel laser cutting and welding, forming notches and angles required for different measurements for comparing whether the measurement is out of limit, filling the gap in the field of coal mine monorail hanging track measurement, and solving the problem of no measuring instruments for track quality due to the particularity of coal mine monorail hanging tracks suspended in the airway, ensuring efficient and accurate measurement functions in the coal mine operating environment.

[0013] 2. The measuring model ruler provided by the utility model can be carried by one person, and can realize the rapid measurement of key parameters of the monorail track laying quality, providing comprehensive and accurate data support for the evaluation of track laying quality. Moreover, the measuring rod is retractable and can be widely used for track measurement needs at different heights, ensuring flexibility and adaptability during operation. The direct comparison measurement method does not require complicated operating steps, and the measurement process is simple and intuitive, which can quickly determine whether the track laying quality exceeds the limit or is qualified.

[0022] Table 1 Design parameters of monorail crane track

[0023]

[0024] like Figure 1-4 As shown, the utility model is a portable measuring model ruler for a monorail hanging track, including a measuring rod 6 made of aluminum alloy, which can be extended in three stages. A measuring ruler 8 is connected to one end of the measuring rod 6, and the measuring ruler 8 is made of high-carbon steel with a thickness of 3 mm by laser cutting and welding. A handle 7 is connected to the other end of the measuring rod 6, and a rubber sleeve is provided on the outer cover of the handle 7 for anti-slip. A track convex part vertical swing angle measuring part 1 is provided on one side of the measuring ruler 8, which is used for measuring the swing angle under the vertical curve and the horizontal left and right swing angles. A track concave part vertical swing angle measuring part 2 is provided on the other end, which is used for measuring the swing angle on the vertical curve. Among them, the swing angles of the track convex part vertical swing angle measuring part 1 and the track concave part vertical swing angle measuring part 2 are both 7°. The outer edge of the measuring ruler 8 below the track concave vertical swing angle measuring part 2 is provided with a track joint gap measuring part 3 and a track joint left and right deviation measuring part 4 from top to bottom. The track joint gap measuring part 3 is 3mm thick and is used to measure the track joint gap. The track joint left and right deviation measuring part 4 is a notch formed by laser cutting 1mm on the measuring ruler 8, which is used to measure the horizontal left and right deviation of the track joint. A 2mm notch is laser cut at the corner of the measuring ruler 8 below the track joint left and right deviation measuring part 4 as the track joint height deviation measuring part 5, which is used to measure the vertical up and down deviation of the track joint.

[0025] When measuring, adjust the extension distance of the measuring rod 6 according to the different track heights, then hold the handle 7, and place the vertical swing angle measuring part 1 of the track convex part at the vertical swing angle of the track convex part. If they fit perfectly, it means that the vertical swing angle of the track convex part is 7°, which meets the requirements; then place the vertical swing angle measuring part 2 of the track concave part at the vertical swing angle of the track concave part. If they fit perfectly, it means that the vertical swing angle of the track convex part is 7°, which meets the requirements. Then place the track joint gap measuring part 3 at the track joint gap, and it just fits in, which means that the distance of the track joint gap is 3mm, which meets the requirements. Finally, place the left and right deviation measuring part 4 of the track joint at the track joint to measure the left and right deviations, leaving a margin, which means that the left and right deviations at the track joint do not exceed 1mm, which meets the requirements, and place the height deviation measuring part 5 of the track joint at the track joint to measure the height deviations, leaving a margin, which means that the height deviations at the track joint do not exceed 2mm, which meets the requirements.
