[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1 like Figure 1 As shown in the figure, this embodiment proposes a rail grinding and rust removal device with dust removal function, including a frame module 1, a grinding module 2 and a dust collection module 4. The grinding module 2 and the dust collection module 4 are both integrated onto the frame module 1 by bolts.

[0037] Preferably, the dust collection module 4 is arranged on the rear side of the polishing module 2 to facilitate dust collection.

[0038] Preferred, such as Figure 2As shown, the frame module 1 includes a frame 1-1, a handle 1-2, a running wheel 1-3, and an anti-tipping auxiliary wheel 1-4; The frame 1-1 has pre-drilled mounting holes for assembly with other components, and structural holes to enhance the structure while reducing weight. The bottom of the frame 1-1 is equipped with the running wheel 1-3, which is used to travel on the top surface of the rail 5. The wheel surface of the running wheel 1-3 is designed with rubber coating (that is, a layer of elastic rubber material is wrapped on the running wheel 1-3) to overcome the longitudinal slope of the line, so that the running wheel 1-3 can travel stably on the top surface of the rail 5. The handle 1-2 is fixedly installed on the frame 1-1. The frame 1-1 can be moved forward along the rail 5 by pushing the handle 1-2, or the frame module 1 can be stabilized by the handle 1-2 so that it can move stably on the rail 5. At least one set of anti-overturning auxiliary wheels 1-4 are symmetrically installed at the bottom of the frame 1-1. The anti-overturning auxiliary wheels 1-4 are used to travel on the rail feet of the rail 5. The anti-overturning auxiliary wheels 1-4 are arranged in pairs and can play an anti-overturning role in superelevated sections.

[0039] Preferably, the handle 1-2, the wheel frame of the running wheel 1-3, and the wheel frame of the anti-tipping auxiliary wheel 1-4 are all connected to the frame 1-1 by bolt pairs.

[0040] Preferred, such as Figure 3 As shown, the grinding module 2 includes a grinding motor 2-1, a lifting mechanism 2-2, a control motor 2-3, and a grinding head 2-4; The grinding head 2-4 is fixedly connected to the output shaft of the grinding motor 2-1, and the grinding motor 2-1 is used to provide power for the grinding action; like Figure 4 As shown, the lifting mechanism 2-2 includes a rotating wheel 2-2-1, a first threaded rod 2-2-2, a lifting box 2-2-3, and a connecting seat 2-2-4; The rotating wheel 2-2-1 is fixedly connected to one end of the first threaded rod 2-2-2. Rotating the rotating wheel 2-2-1 can drive the first threaded rod 2-2-2 to rotate. The rotating wheel 2-2-1 is a hand-cranked rotating wheel. The lifting box 2-2-3 is threadedly connected to the first threaded rod 2-2-2; The lifting box 2-2-3 is arranged between the two connecting seats 2-2-4. The two connecting seats 2-2-4 are respectively arranged on the upper and lower sides of the lifting box 2-2-3. The two ends of the first threaded rod 2-2-2 are respectively hinged to the two connecting seats 2-2-4. The connecting seat 2-2-4 located below the lifting box 2-2-3 is fixedly connected to the frame 1-1. Multiple guide rods 2-2-5 are fixedly connected between the two connecting seats 2-2-4. The multiple guide rods 2-2-5 are arranged around the first threaded rod 2-2-2. The guide rods 2-2-5 are arranged parallel to the first threaded rod 2-2-2. The lifting box 2-2-3 is slidably connected to the guide rods 2-2-5. When the rotating wheel 2-2-1 drives the first threaded rod 2-2-2 to rotate around its axis, under the restriction of the guide rod 2-2-5, the lifting box 2-2-3 will not rotate with the first threaded rod 2-2-2, but will move up and down on the first threaded rod 2-2-2, and slide up and down along the guide rod 2-2-5. like Figure 5 As shown, the grinding module 2 also includes a mounting frame 2-5, and the control motor 2-3 is fixedly mounted on the mounting frame 2-5. The mounting frame 2-5 is also equipped with a grinding head lateral adjustment device. The grinding head lateral adjustment device includes a second threaded rod 2-6-1, which is arranged horizontally. One end of the second threaded rod 2-6-1 is rotatably connected to the mounting frame 2-5, and the other end of the second threaded rod 2-6-1 is fixedly connected to the output shaft of the control motor 2-3. The control motor 2-3 can drive the second threaded rod 2-6-1 to rotate around its axis. The second threaded rod 2-6-1 is connected to a sliding block 2-6-2 by a thread, and the grinding motor 2-1 is fixedly installed on the sliding block 2-6-2; A guide rail 2-6-3 is arranged parallel to each other on both sides of the second threaded rod 2-6-1. The two ends of the guide rail 2-6-3 are fixedly connected to the mounting frame 2-5. The sliding block 2-6-2 is slidably connected to the guide rail 2-6-3. Thus, when the second threaded rod 2-6-1 rotates, the sliding block 2-6-2 will move horizontally on the second threaded rod 2-6-1, thereby driving the grinding motor 2-1 to move horizontally. The grinding motor 2-1 drives the grinding head 2-4 to move horizontally, thereby adjusting the lateral position of the grinding head 2-4 so as to grind different parts of the rail 5.

[0041] The mounting frame 2-5 is fixedly installed on one side of the lifting box 2-2-3. The up-and-down movement of the lifting box 2-2-3 drives the mounting frame 2-5, the control motor 2-3, the grinding motor 2-1, and the grinding head 2-4 to move up and down as a whole, thereby adjusting the vertical position of the grinding head 2-4 so as to grind different parts of the rail 5.

[0042] This invention achieves vertical movement by cooperating with the lifting box 2-2-3 and the first threaded rod 2-2-2, which in turn drives the mounting frame 2-5, the control motor 2-3, the grinding motor 2-1, and the grinding head 2-4 to move vertically as a whole, adjusting the vertical position of the grinding head 2-4. Furthermore, by cooperating with the second threaded rod 2-6-1 through the sliding block 2-6-2, the grinding motor 2-1 and the grinding head 2-4 move horizontally, adjusting the lateral position of the grinding head 2-4. Through the combined action of the lifting mechanism 2-2 and the control motor 2-3, multiple parts of the rail 5 are ground and rusted.

[0043] Preferably, a grinding head 2-4 is arranged on each side of the rail 5 to facilitate simultaneous grinding of both sides of the rail 5. Each grinding head 2-4 is connected to a grinding motor 2-1 for individual control. Each grinding motor 2-1 is mounted on a sliding block 2-6-2, and each sliding block 2-6-2 is individually connected to a second threaded rod 2-6-1. Each second threaded rod 2-6-1 is connected to a control motor 2-3, which individually controls the rotation of each second threaded rod 2-6-1, thereby achieving individual control of the horizontal movement of the two grinding heads 2-4 and making the lateral position adjustment of the two grinding heads 2-4 more precise. Both control motors 2-3 are fixedly mounted on the same mounting frame 2-5.

[0044] Preferred, such as Figure 6 As shown, the dust collection module 4 includes a dust collection motor 4-1, a dust collection bag 4-2, a dust collection box 4-3, a distribution duct 4-4, a suction pipe 4-5, a sealed cover 4-6, and a fixed bracket 4-7. The dust collection motor 4-1 is fixedly mounted on the vehicle frame 1-1, and the dust collection motor 4-1 is used to provide dust collection airflow. The sealed cover 4-6 is fixedly installed on the frame 1-1. Each grinding head 2-4 is placed in a sealed cover 4-6. A flexible sealing layer is provided at the contact point between the sealed cover 4-6 and the rail 5 to provide a sealed environment for dust collection and improve the dust collection effect. The sealed cover 4-6 is fixedly installed on the vehicle frame 1-1 by the fixed bracket 4-7. The fixed bracket 4-7 is fixedly connected to both the vehicle frame 1-1 and the sealed cover 4-6. The fixed bracket 4-7 is used to support the sealed cover 4-6. The two ends of the suction pipe 4-5 are fixedly connected to the sealed cover 4-6 and the air distribution pipe 4-4 respectively, and the suction pipe 4-5 communicates with the interior of the sealed cover 4-6. The suction pipe 4-5 is used to provide a dust collection channel. The air distribution pipe 4-4 is fixedly connected to the air inlet of the dust collection motor 4-1 to provide suction power to the suction pipes 4-5 on the left and right sides. The dust collection bag 4-2 is detachably connected to the dust collection port of the dust collection motor 4-1, and the dust collection bag 4-2 can be quickly removed; the dust collection bag 4-2 is placed in the dust collection box 4-3, and the dust collection box 4-3 is used to store and contain the dust collection bag 4-2.

[0045] The rail grinding and rust removal equipment of the present invention adopts a modular design and is equipped with a grinding module 2 and a dust collection module 4, integrating grinding and rust removal and dust collection functions. It can simultaneously perform rail grinding and rust removal and dust treatment. The dust generated during grinding is collected by the dust collection module 4 to avoid dust pollution to the environment and greatly improve the construction site environment. The rail grinding and rust removal equipment of the present invention has independent but coordinated functions for each module, which reduces system coupling and improves equipment reliability; The double grinding head design of the rail grinding and rust removal equipment of this invention can greatly improve construction efficiency; The rail grinding and rust removal equipment of the present invention adjusts the vertical position of the grinding head 2-4 through the lifting mechanism 2-2 and adjusts the lateral position of the grinding head 2-4 through the control motor 2-3. Through the combined action of the lifting mechanism 2-2 and the control motor 2-3, the distance between the two grinding heads 2-4 and the height of the grinding head 2-4 are changed, realizing multi-directional adjustment of the grinding head 2-4, and realizing integrated grinding and rust removal of multiple parts of the rail 5 (such as rail head, rail web, and rail foot), which can greatly reduce the complexity of on-site tools; The rail grinding and rust removal equipment of the present invention is designed with anti-overturning auxiliary wheels 1-4, which can be applied to monorail working conditions and can play an anti-overturning role in superelevation sections. It can adapt to complex working conditions such as superelevation sections and has high adaptability. The rail grinding and rust removal equipment of the present invention can completely solve the problems of environmental pollution from dust during rail grinding and rust removal and the limited range of rail grinding and rust removal during track construction. At the same time, it can be adapted to single rail working conditions and is easier to use. In summary, the rail grinding and rust removal equipment of the present invention adopts a modular design, has high adaptability, stable grinding quality, high grinding efficiency, and dust removal function.

[0046] Example 2 The difference between this embodiment and Embodiment 1 is that: like Figure 2 , Figure 7 and Figure 8 As shown, the frame module 1 also includes a limiting hinge mechanism 1-5; Preferably, the limiting hinge mechanism 1-5 includes a connecting hinge 1-5-1, a drive motor 1-5-2, a drive wheel 1-5-3, and a limiting clamping mechanism 1-5-4; The drive motor 1-5-2 is fixedly mounted on the mounting bracket 1-5-5. One end of the connecting hinge 1-5-1 is fixedly connected to the mounting bracket 1-5-5, and the other end of the connecting hinge 1-5-1 is hinged to the vehicle frame 1-1. In this way, flat curves can be overcome and small curve radii can be avoided from getting stuck. The drive wheel 1-5-3 is fixedly installed at the bottom of the mounting bracket 1-5-5. The drive wheel 1-5-3 is connected to the drive motor 1-5-2. The drive motor 1-5-2 and the drive wheel 1-5-3 work together to provide the driving force and overcome the longitudinal slope. The drive wheel 1-5-3 is used to travel on the top surface of the rail 5. The limiting clamping mechanism 1-5-4 includes a control handle 1-5-4-1, limiting clamping wheels 1-5-4-2, and connecting rods 1-5-4-3. One end of each of the two connecting rods 1-5-4-3 is connected to a limiting clamping wheel 1-5-4-2. The other end of each of the two connecting rods 1-5-4-3 has a slotted hole, the length of which is the same as the length of the connecting rod 1-5-4-3. The rail is connected by bolt 1-5-4-4, which is located in the strip hole and can slide in the strip hole. The included angle between the two connecting rods 1-5-4-3 is adjustable. The two limiting clamping wheels 1-5-4-2 are located on both sides of the rail 5, facing the rail 5. The limiting clamping wheels 1-5-4-2 are used to travel along the side of the rail head of the rail 5. The control handle 1-5-4-1 includes a push rod 1-5-4-1-1, a hinge rod 1-5-4-1-2, and a handle 1-5-4-1-3. The two ends of the hinge rod 1-5-4-1-2 are respectively hinged to the push rod 1-5-4-1-1 and the handle 1-5-4-1-3. One end of the push rod 1-5-4-1-1 is fixedly connected to the bolt 1-5-4-4, and the other end of the push rod 1-5-4-1-1 is hinged to the hinge rod 1-5-4-1-2. Both the push rod 1-5-4-1-1 and the connecting rod 1-5-4-3 are arranged horizontally. A fixing plate 1-5-4-5 is fixedly connected to one side of the mounting bracket 1-5-4-5. A fixing seat 1-5-4-6 is fixedly installed on the fixing plate 1-5-4-5. One end of the handle 1-5-4-1-3 is hinged to one end of the fixing seat 1-5-4-6. A sliding sleeve 1-5-4-7 is fixedly installed on the other end of the fixing seat 1-5-4-6. The push rod 1-5-4-1-1 is slidably disposed in the sliding sleeve 1-5-4-7. When the handle 1-5-4-1-3 is pressed down, the handle 1-5-4-1-3 rotates about its hinge point with the fixed seat 1-5-4-6. The hinge rod 1-5-4-1-2 is connected to the rod part of the handle 1-5-4-1-3. When the handle 1-5-4-1-3 is pressed down, it will drive the hinge rod 1-5-4-1-2 to rotate. The hinge rod 1-5-4-1-2 pushes the push rod 1-5-4-1-1 towards the end of the connecting rod 1-5-4-3 with the strip hole. The push rod 1-5-4-1-1 causes the bolt 1-5-4-4 to move along the strip hole towards the end of the connecting rod 1-5-4-3, thereby reducing the clamping force between the two connecting rods 1-5-4-3. The angle is adjusted so that the two limiting clamping wheels 1-5-4-2 are clamped on both sides of the rail 5; when the handle 1-5-4-1-3 is lifted, the handle 1-5-4-1-3 rotates in the opposite direction around its hinge point with the fixed seat 1-5-4-6, causing the hinge rod 1-5-4-1-2 to rotate in the opposite direction. The hinge rod 1-5-4-1-2 causes the push rod 1-5-4-1-1 to move toward the end of the connecting rod 1-5-4-3 connected to the limiting clamping wheel 1-5-4-2. The push rod 1-5-4-1-1 causes the bolt 1-5-4-4 to move in the opposite direction, thereby increasing the included angle between the two connecting rods 1-5-4-3, making the clamping degree of the two limiting clamping wheels 1-5-4-2 loosen. The control handle 1-5-4-1 and the limiting clamping wheel 1-5-4-2 are used together to ensure that the vehicle is in close contact with the rail 5 during travel. The control handle 1-5-4-1 can adjust the clamping degree and can cross possible weld bead areas.

[0047] The design of the limiting clamping mechanism 1-5-4 can be applied to monorail working conditions. With the unique design of the connecting hinge 1-5-1 and the drive wheel 1-5-3, it can adapt to complex working conditions such as longitudinal slope and planar curve.

[0048] Example 3 The difference between this embodiment and Embodiment 1 is that: like Figure 1 As shown, the rail grinding and rust removal equipment also includes a control module 3, which is integrated onto the frame module 1 via bolts.
