[0035] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0036] The quick-switching mechanism for contour grinding and corrugated grinding in this application is mainly used for the quick assembly and disassembly of the rail rollers and cross rail rods on the contour grinding machine. It can quickly switch between two different working modes, contour grinding and corrugated grinding, through quick assembly and disassembly, thereby improving the efficiency of rail grinding.
[0037] See Figure 1 and combined Figures 2-3 The quick switching mechanism for contouring and corrugated grinding in this utility model is used for the assembly and disassembly of the rollers and crossbars 3 on the contouring grinding machine 1. The quick switching mechanism for contouring and corrugated grinding includes a roller seat 11 and a crossbar seat 12. By installing the roller seat 11 and the crossbar seat 12 on the body of the contouring grinding machine 1, a structural basis for quick assembly and disassembly of the rollers and crossbars 3 is provided.
[0038] The roller arrangement includes a roller frame 2, which is mainly used to install rollers arranged in rows, thereby forming a roller arrangement structure set on both sides of the profile grinding machine 1.
[0039] In order to enable quick assembly and disassembly of the wheel frame 2 on the profile grinding machine 1, the wheel frame 2 is detachably connected to the wheel seat 11 via the indexing pin 4. At the same time, in order to also enable quick assembly and disassembly of the crossbar 3 on the profile grinding machine 1, the crossbar 3 is also detachably connected to the crossbar seat 12 via the indexing pin 4.
[0040] By setting the indexing pin 4, the rollers and crossbars 3 can be quickly assembled and disassembled on the profile grinding machine 1, which greatly improves the disadvantages of the existing grinding line with a large number of equipment and a large number of operators.
[0041] In one specific embodiment, the wheel seat 11 and the crossbar seat 12 are fixed to the body of the profile grinding machine 1 by bolts and washers, respectively, so as to facilitate the assembly and disassembly of the wheel frame 2 and the crossbar 3 in the profile grinding machine 1.
[0042] The indexing pin 4 includes a pin body 41 and an elastic telescopic pin 42. The pin body 41 is threadedly connected to the wheel seat 11 and the crossbar seat 12. Specifically, the pin body 41 of the indexing pin 4 is fixedly installed on the wheel seat 11 and the crossbar seat 12, while the elastic telescopic pin 42 can move telescopically by the spring installed inside the pin body 41 and external force.
[0043] When installation is required, the elastic telescopic pin 42 is manually pulled outwards, causing its tip to retract into the pin body 41, facilitating the insertion and installation of the wheel frame 2 and the crossrail rod 3. After insertion, the elastic telescopic pin 42 is released, allowing it to return to its original position under spring pressure, extending from the pin body 41 and entering the positioning holes of the wheel frame 2 and the crossrail rod 3, thus locking them in place. Disassembly is achieved by repeating the pulling-out operation of the elastic telescopic pin 42.
[0044] Based on the fixed installation of the indexing pin 4 on the wheel seat 11 and the cross rail seat 12, the wheel seat 11 and the cross rail seat 12 are respectively provided with threaded holes 5 for connecting the pin body 41, which can facilitate the screw connection and fixation of the pin body 41.
[0045] From the perspective of the detachable connection of the wheel, the wheel seat 11 includes a wheel docking sleeve 111, and a threaded hole 5 is provided on the wheel docking sleeve 111. The wheel frame 2 includes a plug tube 21, which is correspondingly provided with the docking sleeve.
[0046] During the assembly process, the insertion tube 21 can be inserted into the docking sleeve, and the insertion tube 21 is provided with a locking hole 8 for the elastic telescopic pin 42 to pass through. The elastic telescopic pin 42 of the indexing pin 4 passes through the locking hole 8 on the insertion tube 21 to achieve the locking of the insertion. At the same time, the locking state can be released by manually pulling out the elastic telescopic pin 42, and then the insertion tube 21 can be removed and disassembled.
[0047] To prevent relative rotation between the insertion tube 21 and the wheel docking sleeve 111, which would affect the stable locking of the elastic telescopic pin 42 between the wheel seat 11 and the wheel frame 2, a notch 6 is provided on the open side of the wheel docking sleeve 111, and a protruding post 7 is provided on the outer wall of the insertion tube 21 to engage with the notch 6.
[0048] During assembly, by inserting the protruding post 7 into the notch groove 6, relative rotation between the insertion tube 21 and the wheel docking sleeve 111 can be prevented, thereby ensuring effective engagement between the two and achieving a double connection state of locking engagement, ensuring stable and reliable connection.
[0049] During the mating process of the wheel docking sleeve 111 and the insertion tube 21, the threaded hole 5 and the notch 6 on the wheel docking sleeve 111 are arranged at intervals along the axial direction of the wheel docking sleeve 111, while the locking hole 8 and the protruding post 7 on the insertion tube 21 are also arranged at intervals along the axial direction of the insertion tube 21. Through this arrangement, two spaced action points in the axial direction of the insertion mating part can be formed, which can ensure the effective and reliable mating relationship.
[0050] From the detachable connection angle of the crossbar 3, the crossbar seat 12 includes a crossbar docking sleeve 121, a threaded hole 5 is provided on the crossbar docking sleeve 121, the side end of the crossbar 3 can be directly inserted into the docking sleeve, and the crossbar 3 is provided with a locking hole 8 for the elastic telescopic pin 42 to pass through.
[0051] Furthermore, the open end of the crossrail rod connecting sleeve 121 is also provided with a notch 6, and the outer side wall of the crossrail rod 3 is provided with a protruding post 7 that can engage with the notch 6.
[0052] The above configuration also allows for a dual connection state with the crossrail rod 3 locked in place, ensuring that the crossrail rod 3 can be quickly assembled and disassembled, while enhancing the stability of the connection state.
[0053] The crossbar 3 in this application mainly serves a supporting function. Specifically, the locking hole 8 and the protruding post 7 on the crossbar 3 are provided at the insertion end of the crossbar 3, and the other end of the crossbar 3 is connected to a traveling roller 31 that can be attached to the rail.
[0054] After the crossbar 3 is inserted into the crossbar seat 12, it is connected to the rail by the traveling roller 31 at the other end, which can maintain the overall balance of the grinding device and carry out stable corrugated grinding.
[0055] In another specific embodiment, the present invention also provides a rail grinding device, including a contour grinding machine 1 and a quick switching mechanism for contour and corrugated grinding as described above, which can realize the quick assembly and disassembly of the rollers and cross rail rods 3 on the contour grinding machine 1, and realize the quick switching between the two working modes of contour grinding and corrugated grinding.
[0056] This invention is based on the existing contour grinding machine 1, with the addition of detachable rollers and crossbars 3. The rollers are used to achieve corrugation grinding, and the crossbars 3 provide support. When the rollers and crossbars 3 are installed, they are used to grind corrugations; when the rollers and crossbars 3 are removed, they are used to grind the profile of the rail for contour grinding.
[0057] By adding detachable roller mechanisms on both sides of the main body of the contour grinding machine 1, and adding a detachable crossbar mechanism 3 in the vertical direction of the machine body, stability and reliability during corrugated grinding are ensured.
[0058] In the specific implementation process, four threaded holes 5 are provided on the side of the body of the contour grinding machine 1 to fix the wheel seat 11; the top surface of the wheel seat 11 is provided with a threaded hole 5 to fix the indexing pin 4. The wheel seat 11 is fixed to the body with bolts and washers. The wheel seat 11 is symmetrically installed on both sides of the body at the same height to ensure that the wheels on both sides are kept at the same height.
[0059] A first mounting base 13 is provided at the handrail of the equipment body for connecting the wheel seat 11 to the first mounting base 13. A threaded hole 5 is provided on the top of the wheel seat 11 for fixing the indexing pin 4. The wheel seat 11 is connected to the first mounting base 13 and fixed with bolts and washers. Similarly, combined with the connection of the crossbar seat 12 to the second mounting base 14 on the equipment body, a contour grinding machine 1 structure that can quickly assemble and disassemble the wheel is formed.
[0060] The wheel arrangement seat 11 and the crossrail seat 12 are provided with notches and slots 6 to prevent the wheel arrangement frame 2 and the crossrail 3 from rotating left and right. The indexing pin 4 is used to lock the wheel arrangement frame 2 or the crossrail 3. Its elastic telescopic pin 42 can be locked by engaging with the locking hole 8 of the wheel arrangement frame 2 or the crossrail 3. The wheel arrangement frame 2 and the crossrail 3 are provided with locking holes 8 with round hole structures to cooperate with the elastic telescopic pin 42 of the indexing pin 4. At the same time, the wheel arrangement frame 2 and the crossrail 3 are provided with protruding pins 7, which are engaged with the notches and slots 6 on the wheel arrangement seat 11 and the crossrail seat 12.
[0061] When the elastic telescopic pin 42 of the indexing pin 4 is lifted, the wheel frame 2 or the cross rail rod 3 is inserted into the mating sleeve of the wheel seat 11 and the cross rail rod seat 12, and the elastic telescopic pin 42 is engaged in the locking hole 8, and the wheel or cross rail rod 3 is installed; when the elastic telescopic pin 42 of the indexing pin 4 is lifted, the wheel or cross rail rod 3 is pulled out, and the disassembly is completed.
[0062] When corrugated grinding is required, install the rollers and crossbar 3; when contour grinding is required, remove the rollers and crossbar 3; disassembly or installation can be completed in just over ten seconds, which is convenient and quick.
[0063] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0064] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
