Description

Technical Field

[0001] This utility model relates to the field of railway measuring instrument technology, and in particular to a turnout tip rail side grinding measuring device. Background Technology

[0002] A turnout is a track connection device that allows trains to switch from one track to another. It is also one of the weakest links in the track, and the wear of its switch rails directly affects the service life of the turnout and the safety of train operation. Currently, high-speed railway turnouts generally suffer from side wear of the switch rails. Existing measuring devices have a relatively cumbersome measurement process, requiring adjustments to height and usage position before measurement can be performed.

[0003] Currently, a search reveals that Chinese utility model patent CN209978768U discloses a gauge for measuring the side wear of a switch rail, comprising a base (1), a bracket (2), a measuring gauge (3), a support arm (4), and a fixing element (5). While this patent can measure the side wear of a switch rail, it still has the following technical drawbacks:

[0004] On the one hand, a magnetic strip is set at the base so that the base can be attached to the upper part of the base of the switch rail. However, this method may cause the magnet to fall off during use, or the magnet to be demagnetized and its magnetic force to weaken, making it inconvenient to take it out after the measurement is completed.

[0005] On the other hand, during the measurement process, the base 1 needs to be attached to the base of the switch rail 10 by magnet first, then the adjusting rod 41 on the support arm 4 needs to be adjusted so that the support arm is supported against the side of the switch rail 10, then the moving seat 51 needs to be adjusted to fix its height, and finally the measuring ruler 3 needs to be moved to measure the wear area on the side of the switch rail 10. The operation is quite cumbersome. After measuring at one position, it needs to be adjusted before measuring at the next position. It cannot quickly and accurately find the wear position on the side of the switch rail. In short, it is often very inconvenient.

[0006] The aforementioned measuring ruler is inconvenient to handle, the magnet may fall off or demagnetize, the adjustment process is cumbersome, and it cannot quickly and accurately locate the wear position on the side of the switch rail. Therefore, the key to solving the above technical problems lies in developing a more practical and efficient switch rail side wear measuring device. Summary of the Invention

[0007] In view of the many defects and shortcomings of the above-mentioned background technology, this utility model has made improvements and innovations, aiming to provide a turnout switch rail side wear measuring device that is small in size, easy to store, and convenient to install and disassemble. By setting a magnetic base, when measurement is needed, the base switch is turned on and the base is attracted to the side rail web of the switch rail; after the measurement is completed, the base switch is turned off, the base no longer generates magnetic force and no longer attracts the side rail web of the switch rail, and can be easily removed.

[0008] Another objective of this invention is to connect the measuring component, connecting seat, and positioning rod into a single unit, thereby fixing the height of the side wear area of ​​the measuring tip rail. In use, simply place the positioning rod in contact with the top surface of the tip rail, then adjust the measuring scale left and right. Based on the scale on the measuring scale and the scale on the measuring scale mounting base used with it, the wear value of the tip rail at that location can be read. By comparing the wear value of the tip rail at that location with the value of the non-wearing tip rail, the wear value of the tip rail side wear can be obtained.

[0043] In summary, the beneficial effects of this utility model compared with the prior art are as follows:

[0044] 1. Because this utility model is equipped with a magnetic base with a switch, during use, the switch on the base can be turned on or off by turning the knob to make the base adsorb or not adsorb on the side of the rail. Compared with the original design of adding a magnet to the base, it can prevent the situation of premature adsorption during installation, which makes it inconvenient to adjust the position and the situation of inconvenience to take it out after measurement.

[0045] 2.

[0046] 3. This utility model uses a knob to allow the magnet to be attracted to or not attracted to the side of the rail web, so that it can be attracted or not attracted according to actual needs during installation. This makes it convenient to adjust the installation position and also makes it easy to remove the base, thus achieving the purpose of saving time and efficiency.

[0047] 4. In this utility model, by connecting the measuring component, the connecting seat and the positioning rod into a whole, and the height between the central axis of the measuring ruler and the positioning rod is 16mm, when the positioning rod is placed on the top surface of the switch rail, the value of the side wear position 16mm below the top surface of the switch rail can be directly measured.

[0048] 5. In this utility model, symmetrical limiting cards are set at the contact surface between the connecting seat and the vertical rod, and are respectively installed in the limiting card slot group of the vertical rod mounting seat, so that the connecting seat can be suspended at any position of the vertical rod during vertical movement.

[0093] Among them, the distance between the bottom of the long rod of the positioning rod 5 and the central axis of the measuring ruler 41 is 16 mm.

[0094] Furthermore, the vertical rod 2 is integrally in a cuboid strip structure, and the lower end of the vertical rod 2 is detachably connected to one side of the non-operation end of the base 1 through a locking member.

[0095] Furthermore, the base 1 includes a mounting box and a box cover detachably connected to the opening end of the mounting box; a connecting rod is rotatably connected to the middle of the box cover, a knob 11 is connected to the outer end of the connecting rod, and a magnet is connected to the inner end of the connecting rod.

[0106] In summary, a more specific embodiment of this utility model is as follows:

[0107] like Figures 3-4 As shown, a turnout tip rail side wear measuring device includes a base 1, a vertical rod 2, a connecting seat 3, a measuring component 4, and a positioning rod 5.

[0108] Before use, the operator first assembles the turnout switch rail side grinding measuring device. First, the measuring ruler 41 is inserted into the transverse groove of the measuring ruler mounting base 32. Then, the adjusting part 42 is threaded into the adjusting thread hole of the connecting base 3, so that one end of the adjusting part 42 is located outside the measuring ruler mounting base 32, and the other end is located in the transverse groove and in contact with the measuring ruler 41.

[0109] Then, the vertical rod 2 is fastened by a bolt, which passes through its lower end and is installed on the non-operating side of the base 1.

[0110] Next, the two limiting cards 8 are installed in the limiting card slots of the vertical rod mounting base 31, and then the vertical rod mounting base 31 is snapped onto the vertical rod 2.

[0111] Finally, the fasteners 7 are sequentially passed through the positioning rod connecting through hole of the positioning rod 5 and the mounting seat through hole of the vertical rod 2, and then connected to the fixing thread hole of the connecting seat 3 to form a whole. The height between the central axis of the measuring scale 41 and the lower part of the positioning rod 3 is 16mm, thus completing the assembly of the device.

[0112] When in use, the operator first places the base 1 on the side rail of the switch rail 6, turns the knob 11 of the base 1 to drive the magnet inside the base 1 to rotate, and the magnet generates magnetic force to make the base 1 adhere to the side rail of the switch rail 6. The position can be adjusted appropriately according to the usage.

[0113] Then, place the positioning rod 5 on the top surface of the switch rail 6, loosen the adjusting piece 42, push the measuring ruler 41 to one side of the switch rail 6 so that the "pen tip" end of the measuring ruler 41 contacts the worn area on the side of the switch rail 6, tighten the adjusting piece 42 to fix the measuring ruler 41 on the measuring ruler mounting base 32, compare the scale value on the measuring ruler 41 with the scale value on the measuring ruler mounting base 32, and you can read the value of the worn area on the side of the switch rail 6 and record it.

[0114] Next, turn the knob 11 on the base 1 to rotate the magnet inside the base 1 so that the base 1 and the side rail of the switch rail 6 are no longer attracted to each other, and remove the entire device.

[0115] Finally, the device is moved to the wear-free switch rail 6 for testing. The above operation is repeated at the wear-free switch rail 6. The value at the wear-free side of the switch rail 6 is read and recorded. The two sets of values ​​are compared to obtain the side wear value of the switch rail at this position and recorded. For example, if the value measured by this measuring device at the top width of the new switch rail is A, and the value measured at the top width of the tested rail is B, then the side wear value of the switch rail at this position is B-A.

[0116] Finally, the operator compares the wear value measured and calculated by the measuring device of this utility model with the allowable wear value of the switch rail side in the actual process. If the wear value is within the normal range of the allowable wear value of the switch rail side, no further processing is required. If the measured wear value is not within the normal range of the allowable wear value of the switch rail side, it means that the switch rail 6 at that location needs to be replaced or repaired.

[0117] After use, the turnout switch rail side wear measuring device should be stored in the designated storage location by the operator for future use.

[0118] In this utility model, two sets of symmetrical inclined grooves are provided at the connection surface between the connecting seat 3 and the vertical rod 2. The limiting card 8 is an elastic soft sheet that can be snapped into the inclined groove on the connecting seat 3. After assembly, the limiting card 8 provides a force to the vertical rod 2, so that when the integrated structure formed by the measuring component 4, the connecting seat 3 and the positioning rod passes through the vertical rod 2, the limiting card 8 provides a lateral force at the connection surface of the vertical rod 2, so that when the integrated structure formed by the measuring component 4, the connecting seat 3 and the positioning rod moves in the vertical direction, it can be suspended at any position.

[0119] In this utility model, the connection is either a fixed connection or a detachable connection. The fixed connection is either a welded connection or a directly machined integral structure, while the detachable connection is either an internal or external threaded connection, a snap-fit ​​connection, or a plug-in structure connection.
