Description

Technical Field

[0001] The utility model relates to a turnout spacer iron detection ruler, belonging to the technical field of measuring equipment. Background Art

[0002] The switch rail inspection ruler is a measuring tool specially used to detect the relevant parameters of railway switch rails. It is generally made of high-strength metals such as stainless steel or aluminum alloy to ensure the rigidity and stability of the ruler body and prevent deformation during use, which would affect the measurement accuracy.

[0003] Chinese patent number CN208254338U discloses a special measuring tool for measuring the size of turnout spacer irons. The tool comprises a main scale and a vernier scale that slides along the main scale. Both the main scale and the vernier scale are printed with scales. A left-position clamp is provided on the left side of the main scale to ensure that the machining dimensions of the spacer irons meet the requirements. Compared with the prior art method of using a template to detect the machining dimensions of the spacer irons, the tool can directly measure the spacing between the rails after the spacer irons are installed, avoiding repeated disassembly and assembly of rail parts and trimming of the spacer irons, thereby improving product processing efficiency.

[0004] During the sliding process of the cursor of the fork spacer iron detection ruler, the friction between the cursor and other parts of the detection ruler may become uneven, thereby aggravating the wear of certain parts, shortening the service life of the detection ruler, making the scale unclear, and easily leading to a decrease in the efficiency of the entire detection process.

[0005] Therefore, a turnout spacer iron detection ruler is proposed. Utility Model Content

[0006] In view of this, the present invention provides a turnout spacer iron detection ruler to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0007] The technical solution of the utility model is achieved as follows: a switch spacer iron detection ruler comprises a strip ruler body, a fixed detection mark rod is fixedly connected to the right side of the upper end of the strip ruler body, a sliding block is slidably connected to the outer end of the strip ruler body, a movable detection mark rod is fixedly connected to the upper end of the sliding block, strip grooves are symmetrically provided at the upper and lower ends of the strip ruler body, a plurality of groups of bracket vertical rods are symmetrically fixedly connected to the upper and lower inner walls of the sliding block, an inner sliding roller is rotatably connected to the ends of the two corresponding bracket vertical rods away from the sliding block, side circular grooves are symmetrically provided at the left and right ends of the inner sliding roller, a spring is fixedly connected to the end of the side circular groove away from the sliding block, and a displacement cylinder is fixedly connected to the end of the spring away from the side circular groove.

[0008] Further preferably, an inner circular groove is formed at one end of the displacement cylinder close to the spring, and the movable detection mark rod and the fixed detection mark rod are arranged horizontally with each other.

[0009] Further preferably, the spring is located in the inner circular groove, and the end of the displacement cylinder away from the spring is fixedly connected to the electromagnetic outer plate.

[0010] Further preferably, the left and right inner walls of the strip-shaped groove are fixedly connected to the metal inner layer, and the electromagnetic outer sheet is magnetically connected to the metal inner layer.

[0011] Further preferably, the displacement cylinder can extend outside the side circular groove, and a control button is installed at the lower end of the sliding block.

[0012] Further preferably, the control button is electrically connected to the displacement cylinder, and a scale is fixedly connected to the front end of the strip ruler body.

[0013] Further preferably, sharp corner indicating pieces are symmetrically fixedly connected to the upper and lower sides of the front end of the sliding block, and the sharp corner indicating pieces cooperate with the scale.

[0014] Further preferably, the inner sliding roller is slidably connected to the strip groove, and the outer end of the strip ruler body is evenly coated with a protective coating.

[0015] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0016] First, in this embodiment, as the sliding block slides outside the strip ruler, strip grooves can be provided on the upper and lower sides of the strip ruler to cooperate with multiple internal sliding rollers, making the sliding block more stable and precise. The cooperation between the strip grooves and the internal sliding rollers can evenly distribute the friction between the sliding block and the strip ruler, avoiding localized excessive wear and preventing the sharp corner indicator from tightly fitting the surface of the strip ruler, especially the scale area. This helps to extend the service life of the strip ruler and reduce the problem of precision loss in related parts due to wear.

[0017] Second, while the slider is sliding left and right on the strip ruler, the control button can be pressed to determine whether the electromagnetic outer plate in the side circular groove is in the energized state. When the slider position needs to be limited, the electromagnetic outer plate is energized, causing the displacement cylinder to pop out of the side circular groove via the spring, so that the electromagnetic outer plate and the metal liner in the strip groove are tightly attached and magnetically attracted, allowing the slider to quickly and accurately stop at the required measurement position, eliminating the need for manual fine-tuning using the roller, saving measurement time and improving detection efficiency.

[0018] The above summary is for the purpose of description only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.

[0028] Example 1

[0029] like Figure 1-5As shown, an embodiment of the present invention provides a switch spacer iron detection ruler, comprising a strip ruler body 1, a fixed detection mark 3 being fixedly connected to the right side of the upper end of the strip ruler body 1, a sliding block 2 being slidably connected to the outer end of the strip ruler body 1, a movable detection mark 15 being fixedly connected to the upper end of the sliding block 2, strip grooves 5 being symmetrically provided at the upper and lower ends of the strip ruler body 1, a plurality of groups of bracket vertical rods 6 being symmetrically fixedly connected to the upper and lower inner walls of the sliding block 2, an inner sliding roller 7 being rotatably connected to the ends of the corresponding two bracket vertical rods 6 away from the sliding block 2, side circular grooves 8 being symmetrically provided at the left and right ends of the inner sliding roller 7, a spring 9 being fixedly connected to the end of the side circular groove 8 away from the sliding block 2, and a displacement cylinder 10 being fixedly connected to the end of the spring 9 away from the side circular groove 8.

[0030] A scale 14 is fixedly connected to the front end of the strip ruler 1. Pointed corner pieces 16 are symmetrically fixedly connected to the upper and lower sides of the front end of the sliding block 2. The pointed corner pieces 16 cooperate with the scale 14. The inner sliding roller 7 is slidably connected to the strip groove 5. The outer end of the strip ruler 1 is evenly coated with a protective coating 17.

[0031] Example 2

[0032] In one embodiment, an inner circular groove 11 is provided at one end of the displacement cylinder 10 close to the spring 9, the movable detection mark 15 and the fixed detection mark 3 are arranged horizontally with each other, the spring 9 is located in the inner circular groove 11, and the end of the displacement cylinder 10 away from the spring 9 is fixedly connected to an electromagnetic outer sheet 12, and the left and right inner walls of the strip groove 5 are fixedly connected to a metal inner layer 13, and the electromagnetic outer sheet 12 and the metal inner layer 13 are magnetically connected. The displacement cylinder 10 can extend outside the side circular groove 8, and a control button 4 is installed at the lower end of the sliding block 2, and the control button 4 is electrically connected to the displacement cylinder 10.

[0033] By pressing the control button 4, it is determined whether the electromagnetic outer sheet 12 in the side circular groove 8 is in the energized state. When the position of the sliding block 2 needs to be limited, the electromagnetic outer sheet 12 is energized to cause the displacement cylinder 10 to pop out of the side circular groove 8 through the spring 9, so that the electromagnetic outer sheet 12 and the metal liner layer 13 in the strip groove 5 are tightly fitted and magnetically attracted, so that the sliding block 2 can be quickly and accurately stopped at the position required for measurement, without the need for manual fine-tuning using the roller, saving measurement time and improving detection efficiency.

[0034] When the utility model is in operation: this solution fits the fixed detection mark rod 3 of the assembled strip ruler body 1 to one side end of the spacer iron, and at the same time, the movable detection mark rod 15 on the sliding block 2 is fit to the other side end of the spacer iron.

At the same time, during the sliding process of the sliding block 2 outside the strip ruler body 1, the strip ruler body 1 can be provided with strip grooves 5 and multiple inner sliding rollers 7 on the upper and lower sides to cooperate with each other, so that the sliding block 2 is more stable and accurate during the sliding process. The cooperation between the strip grooves 5 and the inner sliding rollers 7 can evenly share the friction between the sliding block 2 and the strip ruler body 1, avoiding local excessive wear, so that the sharp corner schematic piece 16 is no longer tightly fitted to the surface of the strip ruler body 1, especially the scale 14 position, which helps The service life of the strip ruler 1 is extended, and the problem of reduced accuracy of related parts due to wear is avoided. At the same time, when the sliding block 2 slides left and right on the strip ruler 1, the control button 4 can be pressed to determine whether the electromagnetic outer plate 12 in the side circular groove 8 is in an energized state. When the position of the sliding block 2 needs to be limited, the electromagnetic outer plate 12 is energized, causing the displacement cylinder 10 to pop out of the side circular groove 8 via the spring 9, so that the electromagnetic outer plate 12 and the metal liner layer 13 in the strip groove 5 are tightly attached and magnetically attracted, so that the sliding block 2 can quickly and accurately stop at the required measurement position, eliminating the need for manual fine-tuning using a roller, saving measurement time and improving detection efficiency. At the same time, a protective coating 17 is provided on the outside of the scale 14. The protective coating 17 can improve the wear resistance of the strip ruler 1, especially the position of the scale 14, thereby ensuring the service life of the strip ruler 1.
