Description

Technical Field

[0001] The utility model belongs to the technical field of electronic measuring devices for guide rail spacing of container ships, and in particular relates to a distance-keeping gauge used for measuring the guide rail spacing of container ships. Background Art

[0002] Guide rails are special equipment to ensure smooth loading and unloading of containers. Figure 4 As shown, the guide rail 4 is made of two rows of vertically erected angle steels 9, arranged from the bottom of the cargo hold to the hatch area, and the upper inclined guide is connected to the horizontal hatch coaming to guide the loading and unloading of containers. The lateral positioning requirements of the guide rail are high. After positioning, the inner distance of the guide rail needs to be checked. If the deviation exceeds the limit, the installation and positioning of the guide rail needs to be adjusted.

[0003] At present, the lateral spacing between two rows of guide rails needs to be measured manually after installation through positioning lines. This measurement method has large errors and low efficiency. In actual production, although multiple sets of data can be measured for a whole guide rail of more than 20 meters in length, the measured data can only measure the guide rail spacing through local points, reflecting the trend of the spacing change, and cannot reflect the continuous value of the spacing between the two rows of guide rails, nor can it measure the straightness of a single guide rail. Utility Model Content

[0004] The utility model aims to provide a distance gauge for measuring the spacing between guide rails of container ships, which effectively solves the problem of large error and low efficiency in the current manual measurement of the lateral spacing between two rows of guide rails.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A distance gauge for measuring the spacing between rails of a container ship comprises a telescopic rod that can be telescoped to the left and right, two abutment parts and three electronic dial indicators with magnetic bases. The left and right ends of the telescopic rod are respectively fixedly connected to an abutment part, and the three electronic dial indicators are respectively fixed to the middle part of the telescopic rod and each abutment part through the magnetic base.

[0007] A double-wheel pulley for sliding along the guide rail is provided on the end surface of each abutting portion opposite to the inner side surface of the guide rail, and the double-wheel pulley is perpendicular to the inner side surface of the guide rail.

[0008] The telescopic rod includes a first steel tube, a second steel tube and a spring. The diameter of the second steel tube is larger than that of the first steel tube. A first steel plate is disposed at the free end of the first steel tube. A second steel plate is disposed inside the second steel tube. Both ends of the spring are respectively connected to the first steel plate and the second steel plate.

[0009] Furthermore, when the distance between the rails of the container ship is equal to the width of the container to be loaded and unloaded, the spring is compressed to half of its stroke, and the reading of the electronic dial gauge located in the middle of the telescopic rod is set to half of the range of the electronic dial gauge.

[0010] Furthermore, the initial reading of the electronic dial gauge located at the abutting portion is set to half of the measuring range of the electronic dial gauge.

[0011] Furthermore, the double-wheel pulley is slidably connected to the middle portion of the inner side surface of the guide rail.

[0012] Furthermore, the first steel pipe and the second steel pipe are both seamless steel pipes.

[0013] Furthermore, the double-wheel pulley is bolted to the abutment portion.

[0014] Compared with the prior art, the beneficial technical effects of the utility model are:

[0015] The utility model adopts electronic dial indicator reading, which is conducive to quickly measuring the distance between the two guide rails and synchronously measuring the straightness of the single-side guide rail; it is conducive to detecting the manufacturing accuracy of the single-side guide rail, facilitating real-time monitoring and analysis of the change of the guide rail distance, avoiding manual measurement and missing measurement points, and significantly improving the measurement efficiency.

[0021] Embodiment 1: A distance gauge for measuring the distance between rails of a container ship, such as Figure 1As shown, it includes a telescopic rod 1 that can be telescoped to the left and right, two abutment parts 2, and three electronic dial indicators 3 with magnetic bases. The left and right ends of the telescopic rod 1 are fixedly connected to an abutment part 2 respectively, and the end surface of each abutment part 2 opposite to the inner side surface of the guide rail 4 is bolted to a double-wheel pulley 5 for sliding along the guide rail 4. The double-wheel pulley 5 is perpendicular to the inner side surface of the guide rail 4, and the sliding of the double-wheel pulley 5 on the guide rail 4 drives the entire distance gauge to move quickly. In this embodiment, the double-wheel pulley 5 is slidably connected to the middle part of the inner side surface of the guide rail 4.

[0022] like Figure 2 As shown, the telescopic rod 1 includes a first steel tube 11, a second steel tube 12 and a spring 6. The diameter of the second steel tube 12 is larger than that of the first steel tube 11, so that the first steel tube 11 can slide inside the second steel tube 12. Figure 1 The right end of the first steel tube 11 is blocked by the first steel plate 7, the interior of the second steel tube 12 is blocked by the second steel plate 8, and the two ends of the spring 6 are respectively connected to the first steel plate 7 and the second steel plate 8, so as to realize the left and right telescopic rod 1. In this embodiment, the first steel tube 11 and the second steel tube 12 are both seamless steel tubes, the diameter of the first steel tube 11 is φ25*3mm, and the diameter of the second steel tube 12 is φ33.7*3.2mm.

[0023] like Figure 1 and Figure 3 As shown, three electronic dial indicators 3 are respectively fixed to the middle of the telescopic rod 1, the side of the abutment portion 2 on the left side, and the side of the abutment portion 2 on the right side through magnetic bases.

[0024] The electronic dial gauge 3 located in the middle of the telescopic rod 1 is used to measure the spacing between the left and right guide rails 4, so as to determine whether the installation accuracy of the guide rails 4 meets the requirements. Specifically, when the spacing between the guide rails 4 of the container ship is the width of the container to be loaded and unloaded (2460mm), the spring 6 is compressed to about half of the stroke, and the reading of the electronic dial gauge 3 located in the middle of the telescopic rod 1 is half of its range. Taking the electronic dial gauge 3 with a range of 25mm as an example, when the measured value of the spacing between the left and right guide rails 4 is 2460mm, the reading of the electronic dial gauge 3 is set to 12mm, then when the reading of the electronic dial gauge 3 is 14mm, the corresponding spacing between the guide rails 4 is 2458mm; when the reading of the electronic dial gauge 3 is 10mm, the corresponding spacing between the guide rails 4 is 2462mm.

[0025] The electronic dial gauge 3 located at the abutment portion 2 is used to measure the straightness of the guide rail 4 on the same side, so as to determine whether the single-side guide rail 4 meets the straightness requirement. Specifically, the initial reading of the electronic dial gauge 3 located at the abutment portion 2 is set to half of its range. Taking the electronic dial gauge 3 with a range of 10mm as an example, the reading is set to 5mm at the beginning of the measurement. After the double-wheel pulley 5 slides from one end of the guide rail 4 to the other end of the guide rail 4, the minimum and maximum values ​​measured by the electronic dial gauge 3 of the single-side guide rail 4 are recorded, and the difference is the straightness of the single-side guide rail 4.

[0026] The utility model starts to move along the guide rail 4 from one end of the guide rail 4, and can directly read the distance value of the guide rails 4 on both sides through the value change of the electronic dial indicator 3 in the middle, so as to directly judge whether the installation accuracy of the guide rail 4 meets the requirements; through the readings of the electronic dial indicators 3 on the left and right sides, the straightness of the single-side guide rail 4 can be directly measured to judge whether the single-side guide rail 4 meets the straightness requirements.

[0027] The utility model adopts the electronic dial indicator 3 reading, which is conducive to quickly measuring the spacing between the guide rails 4 and synchronously measuring the straightness of the single-side guide rail 4; it is conducive to detecting the manufacturing accuracy of the single-side guide rail 4, and is convenient for real-time monitoring and analysis of the spacing changes between the two guide rails 4, avoiding manual measurement and missing measurement points, and significantly improving measurement efficiency.

[0028] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
