[0042] The technical solutions in the utility model will be described below with reference to the drawings.

[0043] In the embodiments of the utility model, the words such as "example" and "for example" are used to represent an example, illustration or explanation. Any embodiment or design scheme described as "example" in the utility model should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the word "example" is intended to present the concept in a specific way. In addition, in the embodiments of the utility model, the meaning expressed by "and / or" can be both, or can be either of the two.

[0044] In order to make the technical problems, technical solutions and advantages of the utility model clearer, the following will be described in detail with reference to the drawings and specific embodiments.

[0045] The utility model embodiment provides a kind of chip stopping device for wheel lathe, Figure 1 It is the top structure schematic diagram of the chip stopping device for wheel lathe provided in the utility model embodiment, please see Figure 1 The chip stopping device is used to install on the preset height of wheel lathe body, and the device includes: wheel set inner cover plate 1, rotating plate 2, push-pull plate 3 and wheel set outer cover plate 4, four are surrounded in the wheel set 20 of the subway vehicle to be lathed and repaired around, and block the iron filings and the like splashed in lathing and repairing process.

[0046] In subway vehicle, the position between a group of wheel sets 20 is called wheel set 20 inside, and the position outside wheel set 20 is called wheel set 20 outside.

[0047] Specifically, the wheel set inner cover plate 1 includes a plurality of inner sub-plates 11, which are hingedly connected through first rotating members 12 to achieve a wave-shaped folding. The wheel set inner cover plate 1 is used to be horizontally installed on a lathe and is arranged at the inner side of a wheel set 20 to be lathed and repaired, so as to achieve chip blocking and provide support at the inner side of the wheel set 20. The first rotating member 12 can be a common hinge, pin shaft or the like, which is arranged at the side of the adjacent inner sub-plates 11 to enable the relative rotation of the inner sub-plates 11 around the first rotating member 12. When the plurality of inner sub-plates 11 are sequentially hingedly connected, the whole can achieve a wave-shaped folding. In the folded state, the inner sub-plates 11 are stacked with each other to form a shape similar to the wave, which greatly reduces the occupied space of the wheel set inner cover plate 1. In the unfolded state, the plurality of inner sub-plates 11 are sequentially laid and connected to form a complete cover plate structure capable of covering the inside of the wheel set 20. Due to the narrow space between the wheel set 20 and the lathe, the folded structure facilitates the movement of the wheel set inner cover plate 1. The wheel set inner cover plate 1 can block the iron filings and other sundries after being unfolded to prevent them from entering the bogie, axle box, primary spring and other running parts of the vehicle body inside the wheel set 20. During the installation, disassembly and wheel set 20 processing, the shape of the cover plate can be adjusted by folding or unfolding, which solves the problem that the device is difficult to install and use due to space limitations and improves the applicability of the chip blocking device.

[0048] Please refer to Figure 2 , Figure 3 , Figure 4 The iron filings flying from the iron filings flying point P are blocked by the chip blocking device 30 for a non-falling wheel lathe and fall back downward to form a blocking range M corresponding to the red line mark above the chip blocking device 30 for the non-falling wheel lathe.

[0049] Specifically, the first rotating member 12 can limit the maximum included angle of the two connected inner sub-plates 11 to 180°, so that the wheel set inner cover plate 1 can remain planar. The structure of the first rotating member 12 can be set as needed, for example, it can be a limiting hinge. Through this structure, the folding form is simple, the operation is convenient, and the space is saved.

[0050] One end of the rotating plate 2 is connected to the outer side of the inner sub-plate 11 at the first end through a rotating shaft 21, that is, the rotating shaft 21 is arranged on the outer side of the inner sub-plate 11 at the first end, and the axis of the rotating shaft 21 is perpendicular to the inner sub-plate 11. By horizontal rotation, the folding and unfolding of the rotating plate 2 are realized. Here, the outer side is also corresponding to the outer side of the wheel set 20. That is, the wheel set inner cover plate 1 is arranged at the inner side of the wheel set 20. Before lathing and repairing, the rotating plate 2 is rotated to the outer side of the wheel set 20. After the lathing and repairing are completed, the rotating plate 2 is rotated to the corresponding inner sub-plate 11 at the inner side of the wheel set 20, so as to leave a passing space of the wheel set 20.

[0051] Specifically, the first end can be corresponding to the outside of the lathe, which has space to accommodate the staff, facilitating the operation of the rotating plate 2, which can be seen in Figure 2 .

[0052] Further, the part of the rotating plate 2 and the inner sub-plate 11 located at the first end overlap is provided with a corresponding pin hole, which is fixed by a positioning pin.

[0053] The push-pull plate 3 is connected to the outside of the inner sub-plate 11 located at the second end, and is pushed and pulled horizontally to realize the expansion and contraction of the push-pull plate 3. Here, the outside is also corresponding to the outside of the wheel set 20. That is to say, the wheel set inner cover plate 1 is arranged inside the wheel set 20. Before the lathe repair, the push-pull plate 3 is pushed and pulled to the outside of the wheel set 20; after the lathe repair is completed, the push-pull plate 3 is pushed and pulled to the corresponding inner sub-plate 11 on the inside of the wheel set 20, so as to leave a passing space for the wheel set 20.

[0054] Specifically, the second end can be corresponding to the side close to the lathe, and the inside of the wheel set 20 of the second end has no operation space, and the outside of the wheel set 20 of the second end has space to accommodate the staff, facilitating the operation of the push-pull plate 3, which can be seen in Figure 2 .

[0055] It can be seen that the rotating plate 2 and the push-pull plate 3 are both expandable plates connected to the wheel set inner cover plate 1, and unique expansion structure forms are designed for the two plates according to the positions of the non-falling wheel lathe body 10 and the wheel set 20, so as to facilitate the operation.

[0056] The wheel set outer cover plate 4 is arranged between the rotating plate 2 and the push-pull plate 3, and together with the wheel set inner cover plate 1, the rotating plate 2 and the push-pull plate 3 forms a relatively closed space around the wheel set 20. Specifically, the wheel set outer cover plate 4 can be detachably connected with the rotating plate 2 and the push-pull plate 3 through clamping structure, connecting structure, etc., which is not limited in the embodiment.

[0057] Based on the above structure, the joint of the wheel set inner cover plate 1 and the wheel set outer cover plate 4 is formed with an opening 5 corresponding to the profile of the wheel set 20, which is installed with a predetermined safety distance between the opening 5 and the wheel set 20, and a gap brush 51 is arranged on the edge of the opening 5 towards the wheel set 20. Based on the above opening 5, the wheel set inner cover plate 1, the rotating plate 2, the push-pull plate 3 and the wheel set outer cover plate 4 etc. are arranged as a baffle around the wheel set 20, thereby forming a chip blocking area around the wheel set 20, which blocks the iron filings and other sundries generated in the non-falling wheel lathe machining process from splashing out, protecting the surrounding environment and equipment from being polluted and damaged by iron filings. The gap brush 51 is used to fill the gap between the baffle and the wheel set 20.

[0058] Please refer to Figure 3 and Figure 4It is to be noted that after the installation height of the scrap blocking device is determined, the profile along the installation height of the wheel set 20 is profiled, and a safety distance of 8-10 mm can be kept between the cover plate and the wheel set 20. The opening 5 corresponding to the profile of the wheel set 20 can better fit the shape of the wheel set 20, and the possibility of leakage of iron scraps from the opening 5 is reduced. The preset distance between the opening 5 and the wheel set 20 ensures that the device does not interfere with the wheel set 20, and effectively blocks the iron scraps. The gap brush 51 at the edge of the opening 5 further enhances the blocking effect of the iron scraps, which can capture and block the fine iron scraps, preventing them from entering the inside of the wheel set 20 through the gap of the opening 5. Specifically, the gap brush 51 can be a h-shaped anti-static machine tool dustproof gap brush 51.

[0059] The number of the above-mentioned wheel set inner cover plates 1 can be set according to needs, for example, can be 3-10, and the number of other plate bodies is correspondingly set. Taking the number of the inner cover plates as 5, the rotating plate 2 as 1, the push-pull plate 3 as 1, and the number of the wheel set outer cover plates 4 as 3.

[0060] Based on the limit contour of the non-falling wheel lapper when working and the limit contour of the vehicle bottom, the scrap blocking device is designed, and neither the outer edge of the cover plate nor the opening 5 interferes with other equipment. During the lapping and repairing process, the device and the vehicle do not interfere with each other and do not affect the observation of the working state of the equipment, and can effectively block all the splashing iron scraps. When the train needs to run on the track, the wheel set outer cover plate 4 can be disassembled in advance, the rotating plate 2 and the push-pull plate 3 are folded and fixed, and there is no need to disassemble and assemble frequently. When the train wheel is in place, the rotating plate 2 and the push-pull plate 3 are unfolded, and the wheel set outer cover plate 4 is installed, which is simple and convenient to operate. Moreover, it has good energy-saving and environmental protection performance, is a pure mechanical design, has zero pollution, and has no noise.

[0061] The scrap blocking device for the non-falling wheel lapper provided by the utility model can block the iron scraps inside the wheel set 20 and provide support at the same time by installing the foldable and storable wheel set inner cover plate 1 on the non-falling wheel lapper body 10. The inner sub-plate 11 at both ends of the wheel set inner cover plate 1 is further connected with the expandable plate body, and the wheel set outer cover plate 4 is further installed between the expandable plate bodies in a split type. The opening 5 for accommodating the wheel set 20 is formed between the wheel set inner cover plate 1 and the wheel set outer cover plate 4, and the gap brush is arranged on the opening 5. Therefore, the device can be surrounded around the wheel set 20 as a baffle, thereby forming a scrap blocking area around the wheel set 20, effectively blocking the splashing iron scraps, and not interfering with other equipment. The scrap blocking device is simple and convenient to operate, and can eliminate the safety hazard.

[0062] Further, the device does not affect the observation of the working state of the equipment, has good energy-saving and environmental protection performance, is a pure mechanical design, has zero pollution, and has no noise. The structure is simple, and the device is easy and reliable to install.

[0063] In one embodiment of the utility model, the inner subboard 11 of the second end is provided with a clamping strip 13, a gap is formed between the clamping strip 13 and the inner subboard 11, the push-pull plate 3 is inserted into the gap, and the inner and outer ends of the push-pull plate 3 are both provided with a first clamping plate 31 bent upwards. The clamping strip 13 and the first clamping plate 31 are used for limiting the push-pull plate 3, avoiding the push-pull plate 3 from falling off the inner subboard 11 of the second end.

[0064] When the overall length and position of the scrap blocking device need to be adjusted, the operator can push and pull the push-pull plate 3. Since the push-pull plate 3 is inserted into the gap formed between the clamping strip 13 and the inner subboard 11, this structure provides a guide function for the movement of the push-pull plate 3, ensuring that the push-pull plate 3 can move smoothly along the predetermined direction. The first clamping plate 31 bent upwards at both ends of the push-pull plate 3 can prevent the push-pull plate 3 from falling out of the gap during movement, playing a limiting role.

[0065] Further, the clamping strip 13 and the push-pull plate 3 are also fixed by a pin or a screw.

[0066] In addition, the first clamping plate 31 located at the outer end of the push-pull plate 3 is also used for limiting the wheel pair outer cover plate 4, preventing the wheel pair outer cover plate 4 from being separated from the push-pull plate 3.

[0067] Further, in one embodiment of the utility model, the outer end of the rotating plate 2 is provided with a second clamping plate 22 bent upwards.

[0068] Specifically, the second clamping plate 22 is connected to the main body of the rotating plate 2 and is bent upwards at a perpendicular or approximately perpendicular angle, forming a protruding structure. During operation, the second clamping plate 22 can cooperate with the wheel pair outer cover plate 4 or other related components, preventing the wheel pair outer cover plate 4 from being separated from the rotating plate 2, further improving the firmness of the connection. In the vibration environment generated by the wheel drop-off lathe, it can also effectively prevent the loosening and displacement between components, ensuring that the scrap blocking device can continuously and stably block iron filings.

[0069] Further, in one embodiment of the utility model, the end of the rotating plate 2 opposite to the wheel pair outer cover plate 4 is provided with a first clamping part 23; the wheel pair outer cover plate 4 is provided with a second clamping part 43 matched with the first clamping part 23.

[0070] Specifically, the structure of the first clamping part 23 can be in the shape of a protrusion, a clamping groove, a hook, etc. For example, it can be a wedge-shaped protrusion protruding outward, or a clamping groove with a certain depth and shape.

[0071] If the first locking portion 23 is a protrusion, the second locking portion 43 can be a corresponding groove; if the first locking portion 23 is a slot, the second locking portion 43 can be a protrusion that can be inserted into the slot. For example, when the first locking portion 23 is a wedge-shaped protrusion, the second locking portion 43 is a wedge-shaped groove, and the shapes and sizes of the two are matched with each other to achieve a tight fit.

[0072] When it is necessary to connect the rotating plate 2 and the wheel set cover plate 4, the operator brings the rotating plate 2 close to the wheel set cover plate 4, and aligns the first locking portion 23 with the second locking portion 43. During the process of approaching each other, the first locking portion 23 is inserted into the second locking portion 43. For example, if it is a combination of a protrusion and a groove, the protrusion is tightly clamped into the groove, and the friction force is generated by the mutual extrusion of the side walls of the protrusion and the groove to prevent the two from sliding relative to each other; if it is a combination of a slot and an insert, after the insert is inserted into the slot, the inner wall of the slot will constrain the insert and limit its movement in all directions. Through this locking combination, the rotating plate 2 and the wheel set cover plate 4 can be firmly connected together.

[0073] The combination of the first locking portion 23 and the second locking portion 43 makes the connection between the rotating plate 2 and the wheel set cover plate 4 more stable, and compared with the ordinary connection mode, this locking structure can withstand greater external force and vibration without loosening. During the operation of the wheel unloading and turning mill, there will be relatively large vibration and impact force, and the design of the locking portion can ensure that the rotating plate 2 and the wheel set cover plate 4 always remain in a connected state, thereby ensuring the overall stability of the chip blocking device.

[0074] In an embodiment provided by the utility model, the end of the push-pull plate 3 opposite to the wheel set cover plate 4 is provided with a third locking portion 32; the wheel set cover plate 4 is provided with a fourth locking portion 44 matched with the third locking portion 32. The combination of the third locking portion 32 and the fourth locking portion 44 is the same as that of the first locking portion 23 and the second locking portion 43, and details are not repeated here.

[0075] When installing the chip blocking device, the operator can quickly connect the rotating plate 2 and the wheel set cover plate 4 through the locking portion, without the need for complex tools and operations, thereby improving the installation efficiency. Since the rotating plate 2 and the wheel set cover plate 4 are tightly connected, the gap between them is reduced, and the splashing of iron chips and other sundries can be more effectively blocked. The leakage of iron chips from the connection part of the rotating plate 2 and the wheel set cover plate 4 is avoided, and the chip blocking performance of the chip blocking device is further improved, thereby protecting the surrounding equipment and environment.

[0076] In an embodiment provided by the utility model, the wheel set cover plate 4 includes a plurality of outer sub-plates 41, and the plurality of outer sub-plates 41 are hingedly connected through the second rotating member 42 to realize the wave-shaped folding.

[0077] The second rotating member 42 can be a hinge, a pin shaft or other common hinged components, which is arranged at the side of the adjacent outer sub-plate 41 to enable the relative rotation of the outer sub-plate 41 around the second rotating member 42. When a plurality of outer sub-plates 41 are hingedly connected in sequence, the whole can be folded in a wave shape, and in the folded state, the outer sub-plates 41 are stacked on each other to form a shape similar to the wave, thereby greatly reducing the space occupied by the wheel cover plate 4. In the unfolded state, the plurality of outer sub-plates 41 are connected in sequence to form a complete cover plate structure capable of covering the outside of the wheel set 20.

[0078] Before the wheel set 20 is machined on the no-wheel lathe, the operator can adjust the wheel cover plate 4 according to the specific position, size and machining requirements of the wheel set 20. When the chip blocking device needs to be installed or moved, the wheel cover plate 4 can be folded in a wave shape through the second rotating member 42, and at this time, the plurality of outer sub-plates 41 are folded towards each other to reduce the volume of the cover plate, facilitate the movement of the device in the narrow space between the wheel set 20 and the lathe, and facilitate the installation and disassembly of the device. When the wheel set 20 starts to be machined, the folded wheel cover plate 4 is unfolded, and the outer sub-plates 41 are sequentially laid flat to form a complete protective structure wrapping the outside of the wheel set 20, which cooperates with the inner cover plate 1 to jointly block the iron chips and other sundries generated during the machining process. During the machining process, if the chip blocking device needs to be adjusted due to the rotation of the wheel set 20 or other conditions, the hinged structure between the outer sub-plates 41 allows the wheel cover plate 4 to be locally deformed to achieve flexible accommodation, avoid hindering the rotation of the wheel set 20, and at the same time maintain good chip blocking effect.

[0079] Through simple folding and unfolding operations, the wheel cover plate 4 can be converted between different working states without the need for complex tools and cumbersome steps, thereby reducing the difficulty of the operator's work and improving the work efficiency. The hinged structure ensures that the wheel cover plate 4 can be deformed while ensuring that the plurality of outer sub-plates 41 are tightly connected in the unfolded state to form a complete chip blocking surface. Even if the device is affected by vibration or external force during the machining of the wheel set 20, the outer sub-plates 41 can still be stably connected to effectively block the iron chips and other sundries, thereby ensuring the reliability of the chip blocking device.

[0080] In an embodiment of the present application, the device further comprises a base, the base comprising a side plate and a top plate, the end of the top plate being rotatably connected to the side plate; the side plate is fixed to the no-wheel lathe body 10, and the top plate is detachably connected to an inner sub-plate 11.

[0081] The side plate plays a key role in fixing and supporting, and it can be fixed firmly on the no-wheel lathe body 10 by welding, bolt connection or other methods to provide a stable support point for the whole base, thereby ensuring that the base does not shift or shake during the operation of the lathe.

[0082] The end of the top plate and the side plate are connected in a rotatable manner, and the connection can be realized by hinges, rotating shafts 21 and the like. The top plate can rotate around the connecting part with the side plate, and this feature enables the top plate to be folded upward or to one side when the device is not used or needs to be adjusted, thereby reducing the occupied space and facilitating the maintenance of the device and other operations of the chip blocking device. Meanwhile, the top plate is also provided with a detachable connecting structure for connecting an inner sub-plate 11. The detachable connecting manner can be bolt connection, buckle connection and the like, so that the inner sub-plate 11 can be conveniently installed on the top plate, and also facilitates disassembly, replacement or maintenance when needed.

[0083] During installation of the chip blocking device, first, according to the installation height, the side plate is fixed on the wheel head body 10 at a suitable position, the top plate is unfolded, then the inner sub-plate 11 is installed on the top plate through the detachable connecting structure, so as to cooperate with other components to form a complete chip blocking structure.

[0084] Through the firm connection of the side plate and the wheel head body 10, stable support is provided for the entire chip blocking device, so that the device can still remain stable in the working environment of high-speed operation of the lathe and generation of large vibration, and the influence of device shaking on the chip blocking effect or the damage of components is avoided.

[0085] In an embodiment of the utility model, wheel set cover plate 4 and rotating plate 2 are detachably connected through first connecting piece 24, wheel set cover plate 4 and push-pull plate 3 are detachably connected through second connecting piece 33, because wheel set inner cover plate 1, rotating plate 2 and push-pull plate 3 are integral structure, the use of first connecting piece 24 and second connecting piece 33 improves the stability of wheel set cover plate 4. The structure of first connecting piece 24 and second connecting piece 33 can be designed according to the requirement, for example, first connecting piece 24 and second connecting piece 33 can be bolt, pin and the like structure.
