[0001] The utility model relates to the technical field of inspection track mud removal and cleaning, in particular to a track mud shoveling mechanism. Background Art

[0002] Inspection robots are mostly track-mounted. They are widely used because they can replace human operators in hazardous locations and harsh environments, simplifying installation and freeing up manpower. However, these harsh environments also lead to the constant accumulation of dust, soot, and other debris on the inspection tracks, which eventually solidify into nodules. Currently, single brush cleaning can only remove light dust on the surface, but cannot remove stubborn buildup. This can cause the robot to operate with difficulty or even become blocked, preventing it from completing its full inspection. Utility Model Content

[0025] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0026] Example: As shown in the attached Figure 1-5 As shown, the utility model describes a track mud shoveling mechanism, and each component can be made of stainless steel, including a base 1 for connecting to a track-type inspection robot. Several mounting holes are processed on the base 1, and the base 1 is mounted on the frame of the track-type inspection robot by bolts.

[0027] A shovel block 2 is provided at the front end of the base 1, and the shovel block 2 is rotatably connected to the base 1 through a horizontally arranged connecting shaft 3. A first torsion spring 4 is provided between the shovel block 2 and the base 1, and one end of the first torsion spring 4 abuts against the shovel block 2, and the other end abuts against the base 1. The first torsion spring 4 is sleeved on the connecting shaft 3, and a torque is given to the shovel block 2 through the first torsion spring 4, so that the front end of the shovel block 2 remains in a horizontal or obliquely downward extending state.

[0028] A brush 5 is provided at the bottom of the base 1. Preferably, in order to facilitate the replacement of the brush, a mounting strip 51 is provided on the top of the brush 5. A T-shaped mounting groove 13 adapted to the mounting strip 51 is provided at the bottom of the base 1. After the mounting strip 51 is inserted into the T-shaped mounting groove 13, it can be locked with a screw. A clearance fit can also be adopted between the mounting strip 51 and the T-shaped mounting groove 13.

[0029] Preferably, in order to remove the dirt shoveled on the track from the track, the brush 5 is arranged obliquely at the bottom of the base 1, with the front end of the brush 5 close to the shovel block 2 and the rear end away from the shovel block 2. During the forward movement of the base 1, the dirt shoveled by the shovel block 2 moves along the length direction of the brush 5, and the dirt shoveled by the shovel block 2 can be cleaned to the outside of the track 8.

[0030] Preferably, the shovel block 2 includes a U-shaped frame 21 and a shovel head 22 arranged at one end of the U-shaped frame 21. The front end surface and the top surface of the shovel head 22 are both inclined surfaces. The U-shaped frame 21 is provided with a through hole 23 adapted to the connecting shaft 3 at the corner away from the shovel head 22. The connecting shaft 3 can rotate in the through hole 23. Under the action of the first torsion spring 4, the front end of the shovel head 22 is maintained in a horizontal or obliquely downward extending state.

[0031] Furthermore, a baffle 24 is provided above the shovel head 22, and the baffle 24 can be fixed to the U-shaped frame 21 by screws. The shovel head 22 and the baffle 24 form a V-shaped structure, and the baffle can block various lumps shoveled down to prevent the rear structure from being stuck.

[0032] Preferably, the front end of the base 1 is provided with a U-shaped mounting position 11 adapted to the shovel block 2, the U-shaped mounting position 11 is provided with a mounting hole adapted to the connecting shaft 3, and the bottom of the rear end of the inner side of the U-shaped mounting position 11 is provided with an abutment slope 12 adapted to the rear end face of the shovel block 2. Under the action of the first torsion spring 4, the rear end face of the shovel block 2 is tightly against the abutment slope 12, which also enables the shovel block 2 to maintain a constant distance from the track surface in the absence of external force.

[0033] There is a certain distance between the shovel block 2 and the track surface. The closer the distance is, the better it is. It depends on the passability of the inspection robot. If the track distance is too close, the installation accuracy requirements at the track connection will increase.

[0034] Preferably, a flip handle 6 is provided on the connecting shaft 3, one end of the flip handle 6 is rotatably connected to the connecting shaft 3, and a flip arm 61 is provided at the end of the flip handle 6 close to the connecting shaft 3, a V-shaped structure is formed between the flip arm 61 and the flip handle 6, and a connecting sleeve adapted to the connecting shaft 3 is provided at the intersection of the flip arm 61 and the flip handle 6. The flip handle 6 is preferably an arc-shaped handle, and an abutment 25 adapted to the flip arm 61 is provided on the shovel block 2. The abutment 25 can be provided at the end of the U-shaped frame 21 away from the shovel head 22, and the U-shaped frame 21 can adopt two A U-shaped frame is provided, and one end of the two U-shaped frames is welded to the shovel head 22, and the other ends of the two U-shaped frames are welded to the abutment part 25, so that the rear end of the U-shaped frame body 21 has an accommodating space, and the flip arm 61 extends to the lower side of the abutment part 25 through the accommodating space. A second torsion spring 7 is provided between the flip handle 6 and the shovel block 2, and one end of the second torsion spring 7 abuts against the flip handle 6, and the other end abuts against the shovel block 2. The second torsion spring 7 is sleeved on the connecting shaft 3, and the torque of the second torsion spring 7 is used to make the flip arm 61 abut against the lower end surface of the abutment part 25.

[0035] Under the action of the first torsion spring 4 and the second torsion spring 7 , the flip handle 6 can maintain a fixed position in the absence of external force.

[0036] Preferably, in order to facilitate the installation of the first torsion spring and the second torsion spring, torsion spring connecting grooves 26 are provided on both the left and right ends of the top of the shovel block 2 .

[0037] When in use, the utility model is integrally mounted on a track inspection robot, which, with the help of the power of the track inspection robot, shovels off and crushes the lumps on the track like a shovel, and then sweeps them away with the brush 5. During the shoveling process, the baffle 24 can block the various lumps shoveled off to avoid jamming the mechanism.

[0038] When the rail inspection robot passes through rail hanging point 9, two situations may occur:

[0039] When the forward direction is to the left, Figure 6 As shown, the turning handle 6 overcomes the torsion spring force under the action of the crossbeam on the hanging point 9 and rotates in the opposite direction to the forward direction through the hanging point 9; when the forward direction is to the right, as shown in FIG. Figure 7 As shown, the flip handle 6 overcomes the torsion spring force under the action of the crossbeam on the hanging point 9 and rotates in the opposite direction to the forward direction through the hanging point 9 (because of the limitation of the abutment inclined surface 12, the shovel block 2 will not approach the track 8, and at the same time, there is no limitation for the shovel block 2 to be away from the track 8. When there is an obstacle that is too high, the shovel block 2 can be lifted up to ensure its passability).
