[0026] Figure 11 This is a cross-sectional view of the oil injection assembly of the present invention. Detailed Implementation

[0027] Please see Figure 1 and Figure 2 This invention provides a tunnel trolley template grinding device, comprising: a positioning rail 1, which is arranged along the arc direction of the trolley template 10 and is positioned on the trolley template 10 so that the positioning rail 1 can slide back and forth along the axial direction of the trolley template 10; a slide block 2, which is slidably disposed on the positioning rail 1; a water-injection grinding component 3, which is installed on the slide block 2 to perform water immersion grinding on the trolley template 10 and to perform cleaning operation after water immersion grinding; and an oil injection component 4, which is installed on the slide block 2 to squeeze and inject oil onto the surface of the trolley template 10 after the cleaning operation is completed.

[0028] From the above, it is easy to see that during the grinding process of the tunnel trolley template, the sliding block 2 can be moved back and forth on the positioning rail 1 to achieve the positioning of the water-injection grinding component 3 and the oil injection component 4. This allows the water-injection grinding component 3 to move and grind along the arc-shaped curvature of the tunnel trolley template. Furthermore, the tunnel trolley template can be pre-wetted with water before grinding, thus preventing dust from flying and polluting the surrounding environment. Moreover, at the rear end of the water-injection grinding component 3, the cooperation with the oil injection component 4 facilitates the squeezing and oiling of the surface of the trolley template 10 after cleaning. To ensure that the arc-shaped grinding direction of the trolley template 10 corresponds to the arc-shaped guide direction of the positioning rail 1, the positioning rail 1 is positioned before the water-injection grinding component 3 is immersed in water for grinding. This ensures that the positioning rail 1 is positioned so that it can only slide back and forth along the axial direction of the trolley template 10, thus solving the grinding deviation problem caused by the offset of the positioning rail 1.

[0029] like Figure 1 and Figure 4 As shown, the positioning track 1 includes: an arc-shaped track 11, on which a slide rail 111 is provided for the slide block 2 to slide back and forth, and a fixed gear connected to the slide block 2 is provided on the slide rail 111; a movable base 12, which is installed at both ends of the arc-shaped track 11, and a movable wheel is provided at the bottom of the movable base 12 to drive the arc-shaped track 11 to move back and forth on the working ground; and a positioning component 13, which is installed on the arc-shaped track 11 to lock the end surface and outer surface of the trolley template 10.

[0030] When the positioning track 1 guides the slide block 2, the slide block 2 is installed in the slide rail 111 of the arc track 11. The drive gear of the slide block 2 meshes with the fixed gear in the slide rail 111, allowing the slide block 2 to move back and forth along the arrangement direction of the slide rail 111. Furthermore, by utilizing the movement of the movable base 12 on the working surface, the arc track 11 can be moved along with it to achieve axial grinding of the surface of the trolley template 10. While the arc track 11 moves and grinds along the axial direction of the trolley template 10, the positioning component 13 locks the end surface and outer surface of the trolley template 10 to ensure that the grinding position of the water-injection grinding component 3 does not shift during grinding, and that the oil injection component 4 provides a more uniform oil injection effect.

[0031] In addition, the slide 2 may include a drive motor and a drive gear. The power output end of the drive motor is connected to the drive gear, and the drive gear meshes with a fixed gear in the slide rail 111 to enable the slide 2 to move along the guide direction of the slide rail 111 when the drive motor drives the drive gear to rotate.

[0032] like Figure 4 As shown, the positioning assembly 13 includes: a lateral positioning seat 131, on one side of which a plurality of first guide wheels 1311 corresponding to the outer surface of the trolley template 10 are provided along the axial direction of the trolley template 10; a lateral drive member 132, which is mounted on the arc-shaped track 11 and whose power output end is connected to the lateral positioning seat 131; an end positioning seat 133, on the upper surface of which a plurality of second guide wheels 1331 corresponding to the end surface of the trolley template 10 are provided along the axial direction of the trolley template 10; and an end drive member 134, which is mounted on the lateral drive member 132 and whose power output end is connected to the end positioning seat 133.

[0033] When the positioning assembly 13 locks the outer surface and end surface of the trolley template 10, it drives the lateral positioning seat 131 toward the outer surface of the trolley template 10 by using the power output end of the lateral drive member 132, preferably a cylinder. The lateral positioning seat 131 moves into position when the first guide wheel 1311 contacts the outer surface of the trolley template 10. Specifically, a pressure sensor can be installed on the first guide wheel 1311. When the pressure signal reaches a set value, the lateral drive member 132 will stop outputting power. After the lateral positioning seat 131 is positioned, the end positioning seat 133 is moved toward the end surface of the trolley template 10 by the end drive component 134, preferably a cylinder. When the pressure signal detected by the pressure sensor on the second guide wheel 1331 reaches the set value, the end drive component 134 is controlled to stop driving. This achieves full positioning of the trolley template 10 by the second guide wheel 1331 on the end drive component 134 and the first guide wheel 1311 on the lateral positioning seat 131, so as to ensure the accuracy of the movement position of the water injection and polishing component 3 and the oil injection component 4, thereby ensuring the polishing accuracy and the fullness of oil injection.

[0034] like Figure 3 As shown, the water-injected polishing assembly 3 includes: a polishing assembly 31, which is mounted on the slide 2 to move with the slide 2 and polish the outer surface of the trolley template 10; a water injection assembly 32, which is mounted on the slide 2 and located at the front end of the moving polishing assembly 31 to immerse the outer surface of the trolley template 10 in water before polishing; and a cleaning and scraping assembly 33, which is mounted on the slide 2 and located at the rear end of the moving polishing assembly 31 to clean the wet abrasive material after polishing the outer surface of the trolley template 10.

[0035] During water-injection grinding, the water-injection grinding component 3 wets the outer surface of the trolley template 10 with water before grinding using the water injection module 32. This wetness reduces the adhesion of particles to the outer surface of the trolley template 10 during grinding with the grinding component 31, and also prevents dust generated during grinding. After grinding with the grinding component 31, the wet abrasive material can be directly cleaned by the cleaning component 33, allowing for oiling after cleaning. This integrated grinding and oiling process improves efficiency.

[0036] like Figure 8 As shown, the polishing assembly 31 includes: a polishing motor 311; and a polishing wheel 312. The polishing wheel 312 is mounted on the bottom of the polishing motor 311, and the power output end of the polishing motor 311 is connected to the polishing wheel 312 in a transmission connection.

[0037] When the grinding wheel 312 is installed on one side of the bottom of the grinding motor 311, the power output end of the grinding motor 311 can be connected to the grinding wheel 312 by using a pulley or the like. Then, after the grinding motor 311 is powered on, it can drive the grinding wheel 312 to rotate, so as to achieve grinding treatment on the outer surface of the trolley template 10.

[0038] like Figures 5 to 7 As shown, the water injection assembly 32 includes: a water injection drain 321, with water injection chambers 3211 extending through its upper and lower sides, and a water injection pipe 3212 connected to the water injection chambers 3211 on one side of the water injection drain 321; water-soaked cotton 322, located on both sides of the bottom of the water injection drain 321, to coat the outer surface of the trolley template 10 with water discharged from the bottom of the water injection chambers 3211; a water-driving roller 323, located inside the water injection chambers 3211, the water-driving roller 323 being conical in shape, and having spiral grooves on its surface; a pusher seat 324, slidably located inside the water injection chambers 3211, and having an exhaust groove 3241 on its surface; and a drive gearbox 325. A drive gearbox 325 is located at the bottom of the pusher seat 324. The power output end of the drive gearbox 325 is connected to the water-driving roller 323 via a drive shaft 3251. A pushing power component 326 is installed on the top wall of the water injection chamber 3211. The power output end of the pushing power component 326 is connected to the pusher seat 324. An exhaust rod 327 has an axial cross-section of "T". The upper end of the exhaust rod 327 is connected to the pushing power component 326, and the lower end of the exhaust rod 327 passes through the exhaust groove 3241. When the pusher seat 324 moves downward, the exhaust rod 327 blocks the exhaust groove 3241. When the pusher seat 324 moves upward, the exhaust groove 3241 is opened.

[0039] When the water injection component 32 performs water injection treatment before the grinding component 31 grinds, water is injected into the water injection chamber 3211 through the water injection pipe 3212. At the same time, the drive gear box 325 is driven to rotate by a servo motor, which in turn drives multiple water-driving rollers 323 to rotate, driving the water downward to be discharged from the bottom side of the water injection outlet 321. In order to further increase the water pressure, the pusher 324 can be further moved up and down by the pusher 324, which is preferably a cylinder. When the pusher 324 moves downward and the exhaust rod 327 blocks the exhaust groove 3241, a downward water pressure is formed, so that the water in the water injection chamber 3211 fully contacts the outer surface of the trolley template 10 to fully wet the outer surface of the trolley template 10. In addition, in order to improve the wetting effect on the outer surface of the trolley template 10, the water-soaked cotton 322 moves on the outer surface of the trolley template 10, which can achieve a soft contact with the outer surface of the trolley template 10 to improve the wetting effect.

[0040] like Figure 5 and Figure 6 As shown, the water injection assembly 32 also includes: a guide hose 328, which is connected to the top of the water injection drain 321 and is connected to the water injection chamber 3211; a crossbar 329, which is horizontally installed on the top inner side of the guide hose 328; and a drive motor 330, which is installed on the top of the water injection drain 321. The power output end of the drive motor 330 is connected to a steering rod 3301, and the other end of the steering rod 3301 is connected to the crossbar 329 to drive the crossbar 329 to deflect left and right.

[0041] When the venting groove 3241 and the venting rod 327 are separated, negative pressure can be avoided when the water-driving roller 323 rotates to drive the water downwards. To prevent water leakage from the water injection chamber 3211 of the water injection drain 321 when the water injection assembly 32 rotates to a near-horizontal state, the drive motor 330 can drive the steering rod 3301 to rotate, thereby moving the top side of the guide hose 328 upwards via the crossbar 329. This prevents water from flowing out of the water injection chamber 3211 and contaminating the outer surface of the trolley template 10, thus affecting the oil film already coated on the outer surface of the trolley template 10. The drive motor 330 can be a servo motor.

[0042] like Figure 9 As shown, the cleaning and scraping assembly 33 includes: a first scraper 331 and a second scraper 332. The first end of the first scraper 331 is connected to the first end of the second scraper 332, and the included angle between the first end of the first scraper 331 and the second scraper 332 is less than 180°. The second end of the first scraper 331 is arranged in a direction away from the polishing assembly 31, and the second end of the second scraper 332 is arranged in a direction close to the polishing assembly 31.

[0043] When cleaning the outer surface of the trolley template 10, the scraping assembly 33 can prevent the abrasive from shifting to the already coated oil film by using the second scraper 332 that is significantly inclined toward the grinding assembly 31, and can quickly guide the abrasive to the un-grinded area by using the first scraper 331 that is significantly inclined away from the grinding assembly 31.

[0044] like Figure 10 and Figure 11 As shown, the oil injection assembly 4 includes: an oil injection tank 41, with a pushing groove 411 on one side; a fixed coating wheel 42, which is installed on the bottom side of the oil injection tank 41; a movable frame plate 43, which is slidably disposed on one side of the pushing groove 411; a movable coating wheel 44, which is installed on the bottom side of the movable frame plate 43; and an oil injection power component 45, which is installed on the oil injection tank 41 and whose power output end is connected to the movable frame plate 43 to drive the movable frame plate 43 to squeeze the oil in the oil injection tank 41 back and forth, so as to fully coat the outer surface of the trolley template 10.

[0045] When the oil injection assembly 4 injects oil onto the outer surface of the trolley template 10, the movable frame plate 43 and the movable coating wheel 44 can be driven by the oil injection power component 45, preferably a cylinder, to move back and forth along the pushing groove 411 toward the oil injection tank 41, thereby squeezing the oil back and forth and providing a pushing force toward the outer surface of the trolley template 10. Furthermore, the fixed coating wheel 42 and the movable coating wheel 44 rotate in opposite directions to gather the oil reaching the bottom of the oil injection tank 41 and the bottom of the movable frame plate 43 toward the middle of the fixed coating wheel 42 and the movable coating wheel 44, thereby reducing oil leakage and improving the uniformity of oil coating on the outer surface of the trolley template 10.

[0046] The present invention also provides a grinding method for a tunnel trolley template grinding device, comprising the following steps:

[0047] Step S10: According to the arc shape of the trolley template 10, adjust the positioning rail 1 to lock the trolley template 10;

[0048] Step S20: Control the slide block 2 to slide along the arrangement direction of the positioning track 1 so that the water-injection polishing component 3 can perform water immersion polishing on the outer surface of the trolley template 10 along the arrangement direction of the positioning track 1, and perform cleaning operation after water immersion polishing.

[0049] Step S30: After the cleaning operation is completed, the surface of the trolley template 10 is squeezed and oiled by the oiling component 4.

[0050] In summary, the tunnel trolley template grinding device and method provided by this invention, through the mutual cooperation between the positioning rail 1 and the slide 2, and the positioning cooperation between the positioning rail 1 and the trolley template 10, not only facilitates the movement of the water-injection grinding component 3 and the oil-injection component 4 along the guide direction of the positioning rail 1 for grinding, but also ensures the grinding accuracy of the grinding component 3 on the outer surface of the trolley template 10 and the uniformity of oil injection by the oil-injection component 4 through the accurate positioning of the positioning rail 1. The mutual cooperation between the water-injection grinding component 3 and the oil-injection component 4 not only achieves grinding of the outer surface of the trolley template 10, but also improves grinding efficiency and reduces grinding dust during water injection, while achieving integrated grinding and oil injection, resulting in good grinding effect and sufficient oil injection on the outer surface of the trolley template 10. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0051] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
