Description

Technical Field

[0001] This application relates to the field of track maintenance, and in particular to a rail grinding vehicle. Background Technology

[0002] After long-term operation, rails are prone to defects such as corrugation, side wear, and thickened edges. In order to extend the service life of rails, it is necessary to grind the rails to eliminate surface defects and restore the optimal profile of the rail head to improve the quality of wheel-rail contact.

[0003] Currently, rail maintenance mainly employs a combination of manual inspection and mechanical grinding. Workers first inspect the rails, then use handheld grinding equipment to polish any detected defects. However, manual rail grinding is inefficient and heavily reliant on the experience of the workers, resulting in low maintenance efficiency and quality. Utility Model Content

[0004] In order to improve the maintenance efficiency and quality of rails, this application provides a rail grinding vehicle.

[0005] The rail grinding vehicle provided in this application adopts the following technical solution: A rail grinding vehicle includes a support frame, a traveling mechanism, a grinding machine, and an adjusting mechanism. The support frame is slidably mounted on the rail. The traveling mechanism is mounted on the support frame and is used to drive the support frame to slide along the rail. The grinding machine is slidably mounted on the support frame and is used to grind the rail. The adjusting mechanism is mounted on the support frame and is used to drive the grinding machine to move.

[0006] By adopting the above technical solution, construction workers move the support frame onto the rail to be ground. The walking mechanism drives the support frame to slide along the rail. During the movement, the grinding machine can grind the rail along its length. Furthermore, the position of the grinding machine can be adjusted by the adjustment mechanism to drive the grinding machine to slide according to the different grinding needs at different locations on the rail, effectively improving the maintenance efficiency and quality of the rail.

[0007] Optionally, the adjusting mechanism includes an adjusting seat, a sliding seat, a first push rod, and a second push rod. The adjusting seat is slidably mounted on the support frame in the direction toward the top surface of the rail, and the sliding seat is slidably mounted on the adjusting seat in the direction toward the length of the rail. The grinding machine is mounted on the sliding seat. The first push rod is mounted on the support frame and is used to drive the adjusting seat to slide, and the second push rod is mounted on the adjusting seat and is used to drive the sliding seat to slide.

[0008] By adopting the above technical solution, the first push rod drives the adjusting seat to slide in the direction toward the top surface of the rail. The adjusting seat drives the sliding seat and the grinding machine to move, thereby adjusting the distance between the grinding machine and the rail, and thus adjusting the grinding force and depth of the rail. The second push rod drives the sliding seat to slide in the direction toward the length of the rail, thereby driving the grinding machine to move and adjusting the position of the grinding machine on the rail.

[0009] Optionally, the grinding machine includes a grinding motor and a grinding head, the grinding motor is mounted on a sliding seat, and the grinding head is coaxially mounted on the output shaft of the grinding motor.

[0010] By adopting the above technical solution, the grinding motor is started, and the output shaft of the grinding motor drives the grinding head to rotate, so that the grinding head can grind the rail.

[0011] Optionally, the traveling mechanism includes traveling wheels, driven wheels, and a traveling motor. The traveling wheels and driven wheels are rotatably mounted on the support frame. The traveling wheels and driven wheels are distributed at intervals on the support frame along the length of the rail. The traveling motor is mounted on the support frame and is used to drive the traveling wheels to rotate.

[0012] By adopting the above technical solution, the traveling wheels and driven wheels are spaced apart and abut against the rail along the length of the rail. When the traveling motor is started, the output shaft of the traveling motor drives the traveling wheels to rotate, and the traveling wheels can make the support frame move along the length of the rail.

[0013] Optionally, the support frame is provided with a support mechanism for supporting the support frame. The support mechanism includes a support rod and a support wheel. The support rod is disposed on the support frame, and the support wheel is rotatably disposed on the support rod and is used to travel on the adjacent rail of the rail being ground.

[0014] By adopting the above technical solution, when the support frame slides on the rail, the support wheel travels on the adjacent rail of the ground rail, thereby supporting the support frame through the support rod, effectively improving the stability of the support frame traveling on the rail.

[0015] Optionally, the support frame is provided with a power supply component, which is used to supply electrical energy to the grinding motor, the first push rod, the second push rod and the travel motor.

[0016] By adopting the above technical solution, the power supply components on the support frame directly supply electrical energy to the grinding motor, the first push rod, the second push rod, and the traveling motor, which facilitates the support frame to travel long distances along the rails.

[0017] Optionally, the support frame is provided with a cleaning mechanism for cleaning the polished rail. The cleaning mechanism includes a cleaning frame and a cleaning cloth. The cleaning frame is mounted on the support frame, and the cleaning cloth is mounted on the cleaning frame and covers the rail.

[0018] By adopting the above technical solution, when the support frame moves along the rail to grind the rail, the support frame drives the cleaning frame to move, and the cleaning frame can drive the cleaning cloth to move. The cleaning cloth covering the rail can clean the ground rail and improve the cleanliness of the ground rail.

[0019] Optionally, the cleaning rack is slidably mounted on the support frame in the direction toward the rail, the cleaning rack is provided with a clamp for holding the cleaning cloth, and the support frame is provided with an extension spring for driving the cleaning rack to slide toward the rail.

[0020] By adopting the above technical solution, when facing different sections of the rail, the extension spring drives the cleaning frame to bring the cleaning cloth to the rail, so that it can fit against the rail for cleaning. And by opening the clamp, the cleaning cloth can be removed and replaced conveniently.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The grinding machine can grind the rail along its length. It can also adjust the position of the grinding machine on the rail by sliding the machine through the adjustment mechanism according to the different grinding needs of different parts of the rail, effectively improving the maintenance efficiency and quality of the rail. 2. The support wheels travel on the adjacent rails of the ground rail, thereby supporting the support frame through the support rod, effectively improving the stability of the support frame as it travels on the rails; 3. The extension spring drives the cleaning frame to bring the cleaning cloth against the steel rail, allowing it to adhere to the rail for cleaning. The cleaning cloth can be easily removed and replaced by opening the clamp. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] Example 1: This application discloses a rail grinding vehicle.

[0028] Reference Figure 1 The rail grinding vehicle includes a support frame 1, a traveling mechanism 2, a grinding machine 3, an adjustment mechanism 4, a support mechanism 5, and a power supply component 6.

[0029] Reference Figure 1 The support frame 1 is slidably mounted on the rail, and the traveling mechanism 2 is mounted on the support frame 1. The traveling mechanism 2 is used to drive the support frame 1 to move along the length of the rail. The traveling mechanism 2 includes a traveling wheel 21, a driven wheel 22, and a traveling motor 23. The traveling wheel 21 and the driven wheel 22 are both rotatably mounted on the support frame 1. The traveling wheel 21 and the driven wheel 22 are spaced apart on the support frame 1 along the length of the rail, so that the traveling wheel 21 and the driven wheel 22 can abut against the rail at intervals along the length of the rail. The traveling motor 23 is mounted on the support frame 1, and the output shaft of the traveling motor 23 is coaxially connected to the traveling wheel 21.

[0030] When the walking motor 23 is started, the output shaft of the walking motor 23 drives the walking wheel 21 to rotate. The walking wheel 21 can then drive the support frame 1 to move along the length of the rail. During the movement, the walking wheel 21 and the driven wheel 22 support the support frame 1 and maintain the stability of the support frame 1 on the rail.

[0031] Reference Figure 1 The support mechanism 5 is installed on the support frame 1. The support mechanism 5 is used to support the support frame 1. The support mechanism 5 includes a support rod 51 and a support wheel 52. The support rod 51 is installed on the support frame 1 by bolts. The length of the support rod 51 is the same as the distance between the two sets of rails of the track. The support wheel 52 is rotatably installed on the support rod 51. The support wheel 52 abuts against the adjacent rail of the rail being ground.

[0032] When the support frame 1 moves along the length of the rail, it drives the support rod 51 to move. The support wheel 52 travels on the adjacent rail of the rail being ground, thereby forming a support point on the adjacent rail of the rail being ground. The support rod 51 provides auxiliary support to the support frame 1, effectively improving the stability of the support frame 1 as it travels on the rail. Furthermore, when transferring the support frame 1, the bolts connecting the support rod 51 to the support frame 1 can be removed, allowing the support rod 51 to be disassembled, thus reducing the space occupied by the support frame 1 during transfer.

[0033] Reference Figure 1 , Figure 2 An adjustment mechanism 4 is mounted on a support frame 1. The adjustment mechanism 4 is used to drive the grinding machine 3 to move. The adjustment mechanism 4 includes an adjustment seat 41, a sliding seat 42, a first push rod 43, and a second push rod 44. The adjustment seat 41 is slidably mounted on the support frame 1 in the direction toward the top surface of the rail. The sliding seat 42 is slidably mounted on the adjustment seat 41 in the direction toward the length of the rail. The grinding machine 3 is mounted on the sliding seat 42. The grinding machine 3 is used to grind the rail. The grinding machine 3 includes a grinding motor 31 and a grinding head 32. The grinding motor 31 is mounted on the sliding seat 42. The grinding head 32 is coaxially flanged and connected to the output shaft of the grinding motor 31. The grinding head 32 abuts against the rail. The first push rod 43 is mounted on the support frame 1. The piston rod of the first push rod 43 is connected to the adjustment seat 41. The second push rod 44 is mounted on the adjustment seat 41. The piston rod of the second push rod 44 is connected to the sliding seat 42. In this embodiment, both the first push rod 43 and the second push rod 44 are electric push rods.

[0034] When the support frame 1 moves along the length of the rail, the first push rod 43 and the second push rod 44 are activated, causing the sliding seat 42 to drive the grinding head 32 to contact the rail. As the support frame 1 moves, the grinding motor 31 drives the grinding head 32 to rotate, and the grinding head 32 can grind the rail along the length of the rail. When grinding different parts of the rail, the first push rod 43 can also drive the adjusting seat 41 to slide in the direction toward the top surface of the rail. The adjusting seat 41 drives the sliding seat 42 and the grinding machine 3 to move, thereby adjusting the distance between the grinding machine 3 and the rail, and thus adjusting the grinding force and depth of the rail. The second push rod 44 drives the sliding seat 42 to slide in the direction toward the length of the rail, and the sliding seat 42 can drive the grinding machine 3 to move, adjusting the position of the grinding machine 3 grinding the rail.

[0035] Reference Figure 1 , Figure 2A power supply component 6 is installed on the support frame 1. The power supply component 6 is used to supply electrical energy to the grinding motor 31, the first push rod 43, the second push rod 44 and the walking motor 23. The power supply component 6 can be a battery, a generator, etc. In this embodiment, the power supply component 6 is a diesel generator. The diesel generator is electrically connected to the grinding motor 31, the first push rod 43, the second push rod 44 and the walking motor 23.

[0036] The power supply component 6, which moves with the support frame 1, directly supplies power to the grinding motor 31, the first push rod 43, the second push rod 44, and the travel motor 23, thus avoiding the need for wiring to supply power to the electrical equipment on the support frame 1 and facilitating the long-distance travel of the support frame 1 along the rail.

[0037] The implementation principle of a rail grinding vehicle in Embodiment 1 of this application is as follows: The construction personnel move the support frame 1 onto the rail to be ground, so that the support wheel 52 connected to the support rod 51 abuts against the adjacent rail of the rail to be ground, thus supporting the support frame 1. Then, the travel motor 23 is started, which drives the travel wheel 21 to rotate, thereby driving the support frame 1 to travel along the length of the rail. During the travel, the grinding motor 31 drives the grinding head 32 to rotate, which can grind the guide rail along the length of the guide rail. In addition, the first push rod 43 can drive the adjusting seat 41 to move, and the second push rod 44 can drive the sliding seat 42 to move, thereby adjusting the depth and position of the grinding head 32 in grinding the rail, effectively improving the maintenance efficiency and maintenance quality of the rail.

[0038] Example 2, the difference between Example 2 and Example 1 is as follows: Reference Figure 3 A cleaning mechanism 7 is installed on the support frame 1. The cleaning mechanism 7 is used to polish the polished rail. The cleaning mechanism 7 includes a cleaning frame 71 and a cleaning cloth 72. The cleaning frame 71 is slidably installed on the support frame 1 in the direction toward the rail. The cleaning frame 71 is located behind the support frame 1 in the direction of travel. A clamp 8 is installed on the cleaning frame 71. The clamp 8 is used to clamp the cleaning cloth 72. An extension spring 9 is installed on the support frame 1. The extension spring 9 is connected to the cleaning frame 71. The extension spring 9 always has the tendency to drive the cleaning frame 71 to slide away from the support frame 1.

[0039] The implementation principle of Embodiment 2 of this application is as follows: After the construction personnel fold the cleaning cloth 72, they position and install it on the end of the cleaning frame 71 facing the rail using the clip 8. When the support frame 1 moves along the length of the rail to polish the rail, it drives the cleaning frame 71 to move. The cleaning frame 71 drives the cleaning cloth 72 to move. The extension spring 9 drives the cleaning cloth 72 to abut and cover the rail, cleaning the polished rail and improving the cleanliness of the polished rail. When cleaning different sections of the rail, the extension spring 9 can adapt to the expansion and contraction, so that the cleaning cloth 72 always adheres to the rail for better cleaning.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
