Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicles, and in particular to a brake caliper mounting seat, a brake caliper comprising the brake caliper mounting seat, and a rail vehicle comprising the brake caliper. Background Art

[0002] The brake caliper is an important mechanism on the bogie of a rail vehicle. When braking is required, the brake caliper can clamp the wheels on the bogie. Therefore, the installation stability of the brake caliper is crucial to the operating safety of the rail vehicle.

[0003] The existing brake caliper is mainly fixed to the side beam of the bogie through a vertical plate. The fastening of the vertical plate and the side beam mainly relies on transverse bolts. During operation, due to the action of vertical vibration load, the transverse bolts will be subjected to shear force, which can easily cause the bolts to break, causing the brake caliper to detach from the bogie, thereby affecting driving safety.

[0004] Therefore, how to improve the installation stability of the brake caliper is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0005] One object of the present invention is to provide a brake caliper mounting seat that can effectively improve the installation stability of the brake caliper. Another object is to provide a brake caliper including the above-mentioned brake caliper mounting seat. Another object is to provide a rail vehicle including the above-mentioned brake caliper.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A brake caliper mounting seat includes: an L-shaped mounting seat, a first fastener and a second fastener, the L-shaped mounting seat includes a horizontal plate and a vertical plate, the horizontal plate is used to be placed above the bogie mounting seat, the first fastener is used to pass through the horizontal plate and the bogie mounting seat; the vertical plate is used to be placed on the side of the bogie mounting seat, and the second fastener is used to pass through the vertical plate and the bogie mounting seat.

[0008] The first fastener connects the cross plate and the bogie mounting base, while the second fastener connects the vertical plate and the bogie mounting base. The synergistic action of the first and second fasteners ensures the stability of the brake caliper mounting base. When the first fastener is subjected to a lateral vibration impact load, the second fastener reduces the shear force on the first fastener. Similarly, when the second fastener is subjected to a vertical vibration impact load, the first fastener reduces the shear force on the second fastener, thereby preventing shearing of the first and second fasteners. This improves the stability of the brake caliper mounting base and ensures the braking stability of the brake caliper.

[0009] In some embodiments, an anti-slip stop is provided on the side of the vertical plate facing the bogie mounting seat, and a clamping groove for clamping on the upper surface and lower surface of the bogie mounting seat is formed between the horizontal plate and the anti-slip stop.

[0010] The anti-slip stopper can provide an upward blocking effect on the brake caliper mounting seat. Even if the first fastener breaks, that is, the first fastener loses its load-bearing function, it can still prevent it from falling off under the action of the anti-slip stopper and the second fastener. In addition, the anti-slip stopper can also protect the second fastener to prevent it from breaking due to shear force.

[0011] In some embodiments, the anti-slip stop is a limiting plate arranged on the vertical plate, and the horizontal plate is provided with two first connecting holes for the first fastener to pass through, and the length of the limiting plate along the length extension direction of the clamping groove is less than the minimum spacing between the two first connecting holes.

[0012] The anti-slip stop and the two first connecting holes are designed in the above-mentioned positions mainly to avoid the first fastener. After the two first fasteners are installed through the cross plate and the bogie in sequence from top to bottom, the lower ends of the two first fasteners are respectively located in front of and behind the anti-slip stop, which can prevent the first fasteners from being connected to the anti-slip stop. Therefore, the first connecting hole on the cross plate can be easily aligned with the vertical mounting hole on the bogie mounting seat, thereby facilitating the installation of the brake caliper mounting seat.

[0013] In some embodiments, the vertical plate is provided with a plurality of second connection holes for receiving the second fasteners. Connecting the vertical plate and the bogie mounting seat with the plurality of second fasteners can improve the connection stability of the brake caliper mounting seat.

[0014] In some embodiments, a hinge support is provided at the lower end of the vertical plate, and the hinge support is used to be hinged to the brake caliper via a hinge axis. By hingedly connecting the brake caliper to the brake caliper mounting seat, dynamic changes of the rail vehicle during braking can be adapted.

[0015] In some embodiments, a predetermined angle is formed between the axis of the articulated shaft and the longitudinal extension direction of the cross plate. Specifically, the brake caliper is tilted relative to the brake caliper mounting base. This tilted design allows the brake caliper to be positioned closer to the wheel within a limited space, while simultaneously moving the brake caliper mounting base away from the wheel, thereby preventing the brake caliper mounting base from adversely affecting wheel operation.

[0016] In some embodiments, the transverse plate is provided with a mounting portion for mounting a tread cleaning device. The mounting portion enables installation of the tread cleaning device, eliminating the need to reserve space on the bogie for mounting the tread cleaning device. This allows full utilization of the space on the brake caliper mounting base, effectively improving integration.

[0017] In some embodiments, the transverse plate is provided with two first connection holes, and the mounting portion is located between the two first connection holes. Placing the mounting portion near the middle of the transverse plate can improve the installation stability of the tread cleaning device.

[0018] In some embodiments, a groove is provided at the upper end of the mounting portion, and at least one third connection hole is provided on the mounting portion. The third connection hole is located around the groove, and the groove is configured to engage with a protrusion on the tread cleaning device. The third connection hole is configured to receive a third fastener to secure the tread cleaning device. The engagement of the protrusion and the groove can position the tread cleaning device, and the first fastener can ensure the stability of the tread cleaning device when mounted on the brake caliper mounting base.

[0019] In some embodiments, the L-shaped mounting seat and the mounting portion are integrally formed, which is beneficial for manufacturing and improving the structural strength of the mounting portion.

[0020] A brake caliper comprises the brake caliper mounting seat described in any one of the above items.

[0021] In some embodiments, a hinge support is provided at the lower end of the brake caliper mounting seat, and the brake caliper includes a bearing seat and two clamps hinged to the bearing seat. The bearing seat is provided with a connecting part that cooperates with the hinge support, and the hinge support and the connecting part are hinged through a hinge shaft.

[0022] A rail vehicle comprises the brake caliper described in any one of the above items.

[0023] Compared with the existing technology, the above technical solution has the following advantages:

[0024] The present invention provides a brake caliper mounting seat, comprising: an L-shaped mounting seat, a first fastener, and a second fastener, wherein the L-shaped mounting seat comprises a horizontal plate and a vertical plate. During installation, the horizontal plate is used to be placed above the bogie mounting seat, and the first fastener is used to connect the horizontal plate and the bogie mounting seat; the vertical plate is used to be placed on the side of the bogie mounting seat, and the second fastener is used to connect the vertical plate and the bogie mounting seat. The brake caliper mounting seat is fastened and positioned in both the vertical and transverse directions, and can withstand vertical vibration impact loads, transverse vibration impact loads, longitudinal vibration impact loads, and braking loads, and can effectively improve the connection stability of the brake caliper mounting seat. The first fastener is used to withstand vertical vibration impact loads, longitudinal vibration impact loads, and braking loads, and the second fastener is mainly used to resist transverse vibration impact loads. Through the synergistic effect of the first fastener and the second fastener, the installation stability of the brake caliper mounting seat can be guaranteed.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] Please refer to Figures 1 to 7 , Figure 1 A schematic diagram of the three-dimensional structure of one side of a brake caliper mounting seat provided in a specific embodiment of the present invention; Figure 2 A schematic diagram of the three-dimensional structure of the other side of a brake caliper mounting seat provided by a specific embodiment of the present invention; Figure 3 A schematic structural diagram of a brake caliper mounting seat corresponding to a bogie mounting seat provided by a specific embodiment of the present invention; Figure 4 A schematic structural diagram of a brake caliper mounting seat provided by a specific embodiment of the present invention when installed on a bogie mounting seat; Figure 5A schematic structural diagram of a brake caliper mounting base provided by a specific embodiment of the present invention when a tread cleaning device is installed; Figure 6 A schematic diagram of the outer structure of a brake caliper provided by a specific embodiment of the present invention when installed on a bogie; Figure 7 A schematic diagram of the inner structure of a brake caliper provided by a specific embodiment of the present invention when installed on a bogie.

[0043] A brake caliper mounting seat is provided in an embodiment of the present invention. The brake caliper mounting seat is an intermediate component between the brake caliper 20 and the bogie 30, and plays the role of supporting the brake caliper 20 and mounting the brake caliper 20 on the bogie 30. The brake caliper mounting seat includes: an L-shaped mounting seat 10, a first fastener 110 and a second fastener 120, wherein the L-shaped mounting seat 10 includes a horizontal plate 11 and a vertical plate 12, and the horizontal plate 11 and the vertical plate 12 can adopt an integrally formed structure, such as casting, forging or bending the right plate, etc. The L-shaped mounting seat 10 with an integrally formed structure is conducive to ensuring its structural stability. Of course, other forming methods can also be used, such as welding the horizontal plate 11 and the vertical plate 12. Specifically, a horizontal plate 11 can be welded on the basis of the existing vertical plate 12 to achieve the purpose of modifying the existing brake caliper mounting seat. During installation, the cross plate 11 is positioned above the bogie mounting seat 31, and the first fastener 110 is connected between the cross plate 11 and the bogie mounting seat 31. The first fastener 110 is preferably a bolt, and the cross plate 11 is preferably connected to the upper portion of the bogie mounting seat 31 using multiple bolts. The vertical plate 12 is positioned on the side of the bogie mounting seat 31, and the second fastener 120 is connected between the vertical plate 12 and the bogie mounting seat 31. The second fastener 120 is preferably a bolt, and the vertical plate 12 is preferably connected to the side of the bogie mounting seat 31 using multiple bolts. The brake caliper mounting seat is secured in place both vertically and transversely, capable of withstanding vertical vibration impact loads, transverse vibration impact loads, longitudinal vibration impact loads, and braking loads, effectively improving the connection stability of the brake caliper mounting seat. The first fastener 110 is designed to withstand vertical vibration impact loads, longitudinal vibration impact loads, and braking loads, while the second fastener 120 is primarily designed to resist transverse vibration impact loads. If only the first fastener 110 is provided, when the brake caliper 20 is subjected to longitudinal vibration impact loads, the first fastener 110 will be subjected to tangential loads, which may lead to slippage, loosening, and bending and fracture. If only the second fastener 120 is provided, when the brake caliper 20 is subjected to vertical vibration impact loads, longitudinal impact vibration loads, and braking loads, the second fastener 120 may be subjected to slippage, loosening, and bending and fracture. Therefore, the first fastener 110 and the second fastener 120 provided in the embodiments of the present invention are both indispensable and must work together to ensure the installation stability of the brake caliper mounting base. For example, when the first fastener 110 is subjected to lateral vibration impact loads, the second fastener 120 can reduce the shear force on the first fastener 110. Similarly, when the second fastener 120 is subjected to vertical vibration impact loads, the first fastener 110 can reduce the shear force on the second fastener 120. This prevents the first fastener 110 and the second fastener 120 from shearing, thereby improving the installation stability of the brake caliper mounting base and ensuring the braking stability of the brake caliper 20.

[0044] In some embodiments, as Figures 2 to 4 As shown, an anti-slip stopper 124 is provided on the side of the vertical plate 12 facing the bogie mounting seat 31. Since in the above embodiment, the cross plate 11 is connected to the upper end of the bogie mounting seat 31, the brake caliper mounting seat can be supported by the bogie mounting seat 31. In order to further improve the connection stability of the brake caliper mounting seat, in this embodiment, an anti-slip stopper 124 structure is added to the vertical plate 12, wherein a clamping groove 125 for clamping on the upper and lower surfaces of the bogie mounting seat 31 is formed between the cross plate 11 and the anti-slip stopper 124, so that the brake caliper mounting seat can withstand upward and downward resistance. Even if the first fastener 110 breaks, the anti-slip stopper 124 can also enable the brake caliper mounting seat to withstand vertical vibration impact loads, thereby increasing safety redundancy. Moreover, the anti-slip stopper 124 can also reduce the damage to the first fastener 110 when it is subjected to vertical vibration impact loads. During the specific installation, as shown in FIG. Figure 2 As shown, the clamping groove 125 of the L-shaped mounting seat 10 corresponds to the bogie mounting seat 31. The L-shaped mounting seat 10 is then moved toward the bogie 30 so that the clamping groove 125 is clamped on the upper and lower surfaces of the bogie mounting seat 31. Subsequently, the first fastener 110 is sequentially passed through the cross plate 11 and the bogie mounting seat 31 from top to bottom, and the second fastener 120 is sequentially passed through the vertical plate 12 and the bogie mounting seat 31 from outside to inside. The bogie mounting seat 31 is provided with vertical mounting holes extending vertically and horizontal mounting holes extending inside and outside. The vertical mounting holes are used to pass through the first fastener 110, and the horizontal mounting holes are used to pass through the second fastener 120. When designing the specific hole positions, it is necessary to avoid cross-connection between the vertical and horizontal mounting holes. The number of vertical mounting holes is the same as the number of first connecting holes 111 on the cross plate 11, and the center spacing is the same. Similarly, the number of horizontal mounting holes is the same as the number of second connecting holes 121 on the vertical plate 12, and the center spacing between adjacent holes is the same.

[0045] In some embodiments, as Figure 2As shown, the anti-slip stopper 124 is a limit plate provided on the vertical plate 12. The limit plate can be integrally formed on the inner side of the vertical plate 12, wherein the horizontal plate 11 is provided with two first connection holes 111 for the first fastener 110 to pass through. For example, the two first connection holes 111 can be symmetrically provided on the horizontal plate 11. Specifically, the horizontal plate 11 is a strip plate structure, that is, the length of the horizontal plate 11 along the front-to-back direction of the L-shaped mounting seat 10 is greater than the length of the horizontal plate 11 along the inside-to-outside direction of the L-shaped mounting seat 10, and the two first connection holes 111 on the horizontal plate 11 are distributed along the front-to-back direction of the horizontal plate 11. The length of the limit plate along the length extension direction of the clamping groove 125 is less than the minimum spacing between the two first connection holes 111, wherein the distance between the rear side of the first connection hole 111 located at the front and the front side of the first connection hole 111 located at the rear is the minimum spacing between the two first connection holes 111, and the projection of the limit plate in the top view is located between the two first connection holes 111. The anti-drop stopper 124 is designed with the above-mentioned length and position mainly to avoid the first fastener 110, for example Figure 2 As described above, after the two first fasteners 110 are sequentially passed through the cross plate 11 and the bogie 30 from top to bottom for installation, the lower ends of the two first fasteners 110 are respectively located in front of and behind the anti-slip stop 124, i.e., the first fasteners 110 do not penetrate the anti-slip stop 124. Since the space between the anti-slip stop 124 and the cross plate 11 near the lower end is relatively small, if the anti-slip stop 124 is long, for example, the same length as the cross plate 11, a through hole needs to be provided in the anti-slip stop 124 for the first fasteners 110 to pass through. In this case, it is difficult to align the first connecting hole 111, the vertical mounting hole, and the through hole during installation, resulting in inconvenience in installation. However, the present invention, by adopting the above-mentioned structural design of the anti-slip stop 124, can prevent the first fasteners 110 from penetrating the anti-slip stop 124, thereby facilitating the alignment of the first connecting hole 111 on the cross plate 11 with the vertical mounting hole on the bogie mounting seat 31, thereby facilitating the installation of the brake caliper mounting seat. In addition, the width of the anti-drop stopper 124 along the inner and outer directions of the L-shaped mounting seat 10 is smaller than the width of the horizontal plate 11 along the inner and outer directions. Figure 3 and Figure 4 As shown, during installation, the end surface of the cross plate 11 can contact the bogie 30, and the end surface of the anti-slip stop 124 does not contact the bogie 30 to avoid interference problems. It is only necessary to ensure that the anti-slip stop 124 can play an upward limiting role on the brake caliper mounting seat. In order to reduce the width of the brake caliper mounting seat installed on the bogie mounting seat 31 in the horizontal direction, the vertical plate 12 can be designed with different thicknesses. Specifically, as shown in FIG. Figure 3 and Figure 4As shown, the thickness of the section of the riser 12 located above the upper surface of the anti-slip stop 124 is smaller than the thickness of the section located below the upper surface of the anti-slip stop 124. After the brake caliper mounting seat is installed on the bogie mounting seat 31, the inner side surface of the section of the riser 12 located below the anti-slip stop 124 is not flush with the end surface of the bogie mounting seat 31 facing the riser 12, that is, the inner side surface of the section of the riser 12 located below the anti-slip stop 124 is located on the left side relative to the end surface of the bogie mounting seat 31 facing the riser 12. Figure 4 As shown, if the overall width of the riser 12 is the same as the width of the lower section of the riser 12, after installation, the overall width will be larger than the difference in width between the upper and lower sections of the riser 12. The present invention utilizes the above-described structural design, whereby the width of the upper surface of the anti-slip stop 124 in the inward-outward direction is greater than the width of the lower surface of the anti-slip stop 124 in the inward-outward direction. The structure of the lower section of the riser 12 near the inner side supports the anti-slip stop 124, effectively improving the structural stability of the anti-slip stop 124 when subjected to downward forces. Furthermore, a chamfer or fillet is provided between the end surface of the anti-slip stop 124 facing the bogie mounting seat 31 and the upper surface of the anti-slip stop 124. In addition, a chamfer or fillet is provided between the end surface of the cross plate 11 facing the bogie mounting seat 31 and the lower surface of the cross plate 11. In addition, a chamfer or fillet is provided between the end surface of the bogie mounting seat 31 facing the vertical plate 12 and the upper surface of the bogie mounting seat 31 and the lower surface of the bogie mounting seat 31. Through the above-mentioned chamfer or fillet design, stress concentration can be eliminated to enhance fatigue resistance. It can also play a positioning and guiding role to facilitate the assembly of the brake caliper mounting seat.

[0046] In some embodiments, as Figure 1 and Figure 5As shown, the riser 12 is provided with a plurality of second connection holes 121 for receiving the second fasteners 120. Four second connection holes 121 can be provided on the riser 12, for example, two rows and two columns of second connection holes 121. Accordingly, the bogie mounting seat 31 is also provided with two rows and two columns of transverse mounting holes, with the same spacing as the second connection holes 121. The outer ends of the second connection holes 121 are preferably countersunk holes, and the heads of the bolts can be partially positioned within the countersunk holes. During machining, only the precision of the inner end surfaces of the countersunk holes needs to be ensured to ensure a tight fit with the bolt heads, eliminating the need for high-precision machining of the entire outer end surface of the riser 12, thereby effectively reducing machining costs. The transverse projection of each second connection hole 121 lies within the transverse projection of the two first connection holes 111. It should be noted that the above embodiment is only described using four second connection holes 121 as an example. In addition, two, three or more second connection holes 121 can also be set. For example, for setting two second connection holes 121, the two second connection holes 121 can be distributed vertically, in the front-to-back direction, or in the diagonal direction; for setting three second connection holes 121, the axes of the three second connection holes 121 can be located in the same plane, for example, distributed vertically, in the front-to-back direction, or in the diagonal direction. In addition, the three second connection holes 121 can also be distributed in an equilateral triangle, an isosceles triangle, or a right-angled isosceles triangle, etc.; for the distribution method of a larger number of second connection holes 121, this embodiment will no longer give examples, and the specific selection can be made according to actual needs.

[0047] In some embodiments, as Figure 1 and Figure 2 As shown, a hinge support 122 is provided at the lower end of the vertical plate 12. The hinge support 122 has an N-shaped structure and hinge holes at both ends of the hinge support 122. The hinge support 122 is used to be hinged to the brake caliper 20 via a hinge axis 123. The hinge axis 123 is perpendicular to the second fastener 120, and the brake caliper 20 can swing inward and outward relative to the bogie 30 about the hinge axis 123. During installation, the brake caliper 20 and the brake caliper mounting base can be assembled together first, and then the brake caliper mounting base can be connected to the bogie mounting base 31. When installing the brake caliper 20, the hinge support 122 of the brake caliper mounting base can be aligned with the corresponding connecting portion 211 on the brake caliper 20. The hinge axis 123 is then passed through the hinge support 122 and the connecting portion 211 on the brake caliper 20. Finally, the hinge axis 123 is axially limited at both ends. The hinge axis 123 is preferably a pin. By hingedly connecting the brake caliper 20 to the brake caliper mounting seat, dynamic changes of the rail vehicle during braking can be accommodated. For example, the brake caliper 20 can better accommodate the roll of the wheel 50 during braking.

[0048] In some embodiments, as Figure 2 and Figure 6 As shown, the axis direction of the hinge shaft 123 and the length extension direction of the horizontal plate 11 are provided with a preset angle, such as Figure 6 As shown, the longitudinal direction of the cross plate 11 is horizontal, and the axis direction of the articulated shaft 123 forms a predetermined angle with the horizontal direction. After the brake caliper mounting base is mounted on the bogie mounting base 31, the end of the brake caliper 20 having the clamp 212 is tilted upward. This design can improve the braking effect of the brake caliper 20 on the wheel 50. In the present invention, by tilting the brake caliper 20, the brake caliper 20 can be brought closer to the wheel 50 within a limited space, while the brake caliper mounting base is moved away from the wheel 50, thereby preventing the brake caliper mounting base from adversely affecting the operation of the wheel 50. If the hinge shaft 123 is designed in the horizontal direction, the hinge seat at the lower end of the vertical plate 12 needs to be set in the horizontal direction accordingly, that is, the front and rear end surfaces of the lower end of the vertical plate 12 are extended in the vertical direction. In this structural state, the brake caliper 20 needs to be lengthened in the front and rear directions, which will increase the space occupied by the brake caliper 20 on the bogie 30. Especially for the scenario where the brake caliper 20 is built into the bogie 30, it will increase the difficulty of installation. If it is for easy installation, it is necessary to increase the installation space, which will affect the installation of other parts on the bogie 30. In addition, a weight-reducing hole is provided on the structure between the anti-slip stopper 124 and the hinge support 122 on the vertical plate 12, as shown in FIG. Figure 1 and Figure 2 As shown, the weight of the brake caliper mounting seat can be reduced by the weight-reducing hole. The shape of the weight-reducing hole can be set according to specific circumstances, and this embodiment does not impose any specific limitation on this.

[0049] In some embodiments, as Figure 5 and Figure 6As shown, the transverse plate 11 is provided with a mounting portion 13 for mounting a tread cleaning device 40. Specifically, the tread cleaning device 40 can be integrated into the brake caliper mounting base, thereby eliminating the need for a reserved mounting location on the bogie 30. This fully utilizes the space on the brake caliper mounting base, effectively improving integration. The tread cleaning device 40 removes foreign matter from the tread of the wheel 50, ensuring a clean tread and ensuring good contact between the wheel 50 and the track, thereby reducing problems such as wheel slippage and wear caused by foreign matter accumulation. Importantly, the tread cleaning device 40 improves the operational safety of rail vehicles. The tread cleaning device 40 generally comprises a bracket, a telescopic device, and a cleaning end. The bracket is fixed to the horizontal plate 11 of the brake caliper mounting base, the fixed end of the telescopic device is fixed to the bracket, and the cleaning end is fixed to the movable end of the telescopic device. When cleaning is required, the movable end of the telescopic device extends to drive the cleaning end into contact with the tread of the wheel 50. As the wheel 50 rotates, foreign matter on the wheel 50 is removed. When cleaning is complete, the movable end of the telescopic device drives the cleaning end to retract. The specific structure and operating principle of the tread cleaning device 40 are not described in detail in this embodiment; for details, please refer to the existing art.

[0050] In some embodiments, as Figure 2 、 Figure 5 and Figure 6 As shown, the transverse plate 11 is provided with two first connection holes 111, which are distributed along the front-to-back direction of the transverse plate 11. The mounting portion 13 is located between the two first connection holes 111. Placing the mounting portion 13 near the center of the transverse plate 11 can improve the installation stability of the tread cleaning device 40. Specifically, a horizontally extending connecting plate is provided at the lower end of the bracket of the tread cleaning device 40. The connecting plate is positioned on the connecting portion 211 of the transverse plate 11. The connecting plate and the connecting portion 211 are connected by a third fastener, preferably a screw. The mounting portion 13 preferably protrudes upward from the upper surface of the transverse plate 11. The width of the mounting portion 13 in the inward-outward direction is preferably wider than the width of the transverse plate 11 in the inward-outward direction. Specifically, the outer end surface of the mounting portion 13 protrudes outward from the outer end surface of the transverse plate 11. By increasing the inward-outward width of the mounting portion 13, the contact area between the connecting plate of the tread cleaning device 40 and the mounting portion 13 of the brake caliper mounting seat can be increased, thereby ensuring the installation stability of the tread cleaning device 40.

[0051] In some embodiments, as Figure 2As shown, the upper end of the mounting portion 13 is provided with a groove 131.
