Cleaning tool

Abstract

The application relates to a cleaning tool, which comprises a holding piece, a bearing piece connected to the holding piece, and a cleaning assembly comprising a rolling brush head and a conical brush head. The rolling brush head is rotatably arranged on the bearing piece along an axis extending in a first direction. The conical brush head is connected to the side of the bearing piece far from the holding piece, extends in a second direction, and gradually decreases in cross-sectional size in the second direction. The first direction and the second direction are perpendicular. When the surface of the frog rail and the corresponding wing rail needs to be cleaned, the holding piece is pushed to drive the rolling brush head to rotate around its axis through the bearing piece, so that the rolling brush head can clean the surface of the rail and the wing rail. When the wheel flange groove and the rail gap of the adjacent two rails of the frog need to be cleaned, the conical brush head is used for cleaning. Thus, the frog position is cleaned, and the cleaning efficiency and speed of the frog position are improved.

Description

Technical Field

[0001] This application relates to the field of cleaning devices, and in particular to a cleaning tool. Background Technology

[0002] Currently, with the rapid development of the domestic railway industry, in order to achieve the change of direction during the train's journey, two tracks are connected by turnouts. At the intersection of the two tracks, a frog is formed. The maintenance and repair of the tracks, especially the frog, is becoming increasingly important, as it greatly affects the safety of the train.

[0003] During routine inspections, it is necessary to clean debris and gravel from the frog area, including the wheel flange grooves and surfaces, in order to promptly detect damage and defects in this area, ensure the quality of turnout operation, and safeguard track safety.

[0004] However, there are currently no dedicated tools for cleaning the frog area, making it quite difficult to clean. Utility Model Content

[0005] Based on this, this application provides a cleaning tool to solve the problem of difficult cleaning of the fork section in the related art.

[0006] This application provides a cleaning tool, which includes: a grip; a carrier, the grip being connected to the carrier; and a cleaning assembly including a rolling brush head and a tapered brush head, the rolling brush head being rotatably disposed on the carrier about an axis extending along a first direction; the tapered brush head being connected to the side of the carrier away from the grip, the tapered brush head extending along a second direction, and the cross-sectional dimension of the tapered brush head gradually decreasing in the second direction, the first direction and the second direction being perpendicular to each other.

[0007] In one embodiment, the tapered brush head includes a first brush head and a second brush head arranged sequentially along a first direction. Both the first brush head and the second brush head extend along a second direction and are angled to each other so that the cross-sectional dimension of the tapered brush head gradually decreases in the second direction.

[0008] In one embodiment, the tapered brush head further includes a third brush head extending along a second direction and located between the first and second brush heads.

[0009] In one embodiment, the carrier includes a carrier plate, with rolling brush heads provided at both ends of the carrier plate in the second direction, and a conical brush head located between the two rolling brush heads.

[0010] In one embodiment, the carrier further includes a central shaft that is rotatably disposed on the carrier plate in a second direction, and a rolling brush head is sleeved on the central shaft.

[0011] In one embodiment, the rolling brush head includes a roller and a first cleaning brush disposed circumferentially along the roller, the roller being rotatably disposed on a carrier.

[0012] In one embodiment, the tapered brush head includes a cleaning plate and a second cleaning brush disposed on the cleaning plate, both the cleaning plate and the second cleaning brush extending in a second direction.

[0013] In one embodiment, the grip includes a grip bar that is angled toward the carrier.

[0014] In one embodiment, an anti-slip sleeve is provided at the end of the grip bar away from the carrier.

[0015] In one embodiment, the grip further includes a connecting plate connected to one end of the grip rod near the carrier, and the connecting plate is connected to the carrier.

[0016] Using the technical solution of this application, the operator holds a gripper and uses the gripper and carrier to push the cleaning assembly to clean the frog. When it is necessary to clean foreign objects from the frog's point rail and corresponding wing rail surfaces, pushing the gripper causes it to rotate the rolling brush head around its own axis via the carrier, thereby enabling the cleaning of foreign objects from the point rail and wing rail surfaces using the rolling brush head. When it is necessary to clean the wheel flange grooves of the two adjacent rails of the frog and the gaps in the point rail, a conical brush head is used for cleaning. This achieves cleaning of the frog location, improving the cleaning efficiency and speed at the frog location. Attached Figure Description

Detailed Implementation

[0021] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0022] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0023] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0026] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0027] See Figure 1 and Figure 2 , Figure 1 A schematic diagram of the cleaning tool provided in an embodiment of this application is shown. Figure 2 This illustration shows another structural diagram of the cleaning tool provided in an embodiment of this application. One embodiment of this application provides a cleaning tool including a grip 10, a carrier 20, and a cleaning assembly 30. The grip 10 is connected to the carrier 20. The cleaning assembly 30 includes a rolling brush head 31 and a tapered brush head 32. The rolling brush head 31 is rotatably disposed on the carrier 20 about an axis extending along a first direction X. The tapered brush head 32 is connected to the side of the carrier 20 away from the grip 10, extends along a second direction Y, and its cross-sectional dimension gradually decreases in the second direction Y. The first direction X and the second direction Y are perpendicular to each other.

[0028] Using the technical solution of this application, the operator holds the gripper 10 and uses the gripper 10 and the carrier 20 to push the cleaning assembly 30 to clean the frog. When it is necessary to clean foreign objects from the frog's point rail and the corresponding wing rail surface, by pushing the gripper 10, the gripper 10 drives the rolling brush head 31 to rotate around its own axis via the carrier 20, thereby enabling the cleaning of foreign objects from the point rail and wing rail surface using the rolling brush head 31. When it is necessary to clean the wheel flange grooves of the two rails adjacent to the frog and the gap in the point rail, a conical brush head 32 is used for cleaning. This achieves cleaning of the frog position, improving the cleaning efficiency and speed at the frog position.

[0029] A railway turnout generally includes a switch section, a connecting section, and a frog section. The switch section consists of components such as the stock rail, switch rail, and switch mechanism. The switch rail moves via the switch mechanism, either fitting snugly or separating from the stock rail, thereby guiding the train to run straight or laterally. The connecting section is the track connecting the switch and the frog, including straight and curved rails. The curve connecting the lateral switch rail and the frog toe is called the guide curve. The frog section is the device that allows the wheels to cross over one rail when two rails intersect at a plane. It is generally divided into fixed frogs, which are more common in conventional railways, and movable frogs, which are more common in high-speed railways. Guard rails are usually installed on both sides of the frog to prevent the wheels from derailing. The conical brush head 32 of this application is mainly used for cleaning the wheel flange grooves and the gaps in the frog section.

[0030] It should be noted that, depending on the dimensions at the frog location, when cleaning the flange grooves of the two adjacent rails at the frog, the rolling brush head 31 is located on the outside of the flange grooves of the two adjacent rails, and the flange grooves only need to be cleaned by the conical brush head 32. Furthermore, since the flange grooves at the frog location may gradually decrease in width as the two rails move closer to each other, the conical brush head 32 can be adapted to the shape of the flange grooves for cleaning.

[0031] The operator selects the appropriate brush head based on the comfort of their handheld cleaning tool and the different arrangement shapes of the frog positions. The rolling brush head 31 is suitable for cleaning the outer surface of the rail, while the tapered brush head 32 is suitable for cleaning wheel flange grooves and gaps.

[0032] In other embodiments, the cleaning tool can also be used for grinding and cleaning rail welds and other simple grinding and cleaning operations.

[0033] Since the cleaning tool of this application is used for cleaning railways, the cleaning component 30 should be made of a material with a certain rigidity and wear resistance.

[0034] Combination Figure 1 As shown, the tapered brush head 32 includes a first brush head 321 and a second brush head 322 arranged sequentially along a first direction X. Both the first brush head 321 and the second brush head 322 extend along a second direction Y. The first brush head 321 and the second brush head 322 are set at an angle so that the cross-sectional dimension of the tapered brush head 32 gradually decreases in the second direction Y. The tapered brush head 32 with the above design can use the first brush head 321 and the second brush head 322 to clean debris, which is convenient for strengthening the cleaning of the frog section's center rail.

[0035] Wherein, the first direction X corresponds to the width direction of the rail, and the second direction Y corresponds to the length direction of the rail extension. In the direction in which the cleaning tool moves forward, the cross-sectional dimension of the tapered brush head 32 gradually decreases in the second direction Y.

[0036] Combination Figure 1 As shown, the tapered brush head 32 also includes a third brush head 323, which extends along the second direction Y and is located between the first brush head 321 and the second brush head 322. By placing the third brush head 323 between the first brush head 321 and the second brush head 322, the cleaning ability can be further enhanced.

[0037] In some embodiments, in the second direction Y, both the first brush head 321 and the second brush head 322 move closer to the third brush head 323.

[0038] Combination Figure 2 As shown, the support member 20 includes a support plate 21, with rolling brush heads 31 provided at both ends of the support plate 21 in the second direction Y, and a conical brush head 32 located between the two rolling brush heads 31. With this design, by providing two rolling brush heads 31, the rail surface can be cleaned separately using the two rolling brush heads 31, thereby improving cleaning capacity.

[0039] In some embodiments, depending on the size of the rails, cleaning the surface of the frog or wing rails may only require one rolling brush head 31. The operator can choose either rolling brush head 31 based on their own comfort, with the other rolling brush head 31 serving as a backup. Of course, when the distance between the two rails is exactly the same as the distance between the two rolling brush heads 31, each rolling brush head 31 can be assigned to one rail, meaning that the two rolling brush heads 31 can be used to clean the two rails separately.

[0040] By placing both the rolling brush head 31 and the conical brush head 32 on the support plate 21, the size of the tool is reduced, the integration of the tool is improved, and the ease of use is enhanced.

[0041] Combination Figure 2 As shown, the carrier 20 also includes a central shaft 22, which is rotatably mounted on the carrier plate 21 along the second direction Y. The rolling brush head 31 is sleeved on the central shaft 22. With the above design, by connecting the rolling brush head 31 to the central shaft 22, the rolling brush head 31 can be made more stable when rotating, so as to ensure that the rolling brush head 31 has better cleaning ability.

[0042] To reduce the friction between the central shaft 22 and the support plate 21, a bearing can be installed between the central shaft 22 and the support plate 21 to reduce the relative wear between the central shaft 22 and the support plate 21 and extend the service life of the tool.

[0043] In some embodiments, the rolling brush heads 31 at both ends of the support plate 21 are sleeved on the central shaft 22. The rotation of the central shaft 22 is achieved by the operator pushing the cleaning tool to drive the rolling brush heads 31 to rotate.

[0044] Combination Figure 1 As shown, the rolling brush head 31 includes a roller 311 and a first cleaning brush 312 arranged circumferentially along the roller 311. The roller 311 is rotatably mounted on the support member 20. The rolling brush head 31 described above has the advantages of simple structure and easy processing.

[0045] The first cleaning brush 312 can be a cleaning brush with various structures. For example, the first cleaning brush 312 can be a cleaning brush structure with multiple clusters of steel wires.

[0046] Combination Figure 1 As shown, the conical brush head 32 includes a cleaning plate 324 and a second cleaning brush 325 disposed on the cleaning plate 324. Both the cleaning plate 324 and the second cleaning brush 325 extend along the second direction Y. The conical brush head 32 with the above design has the advantages of simple structure and easy processing.

[0047] In some embodiments, the first brush head 321, the second brush head 322, and the third brush head 323 have the same structure and can all be designed to cooperate with the cleaning plate 324 and the second cleaning brush 325 as described above.

[0048] Combination Figure 1 As shown, the grip 10 includes a grip rod 11, which is set at an angle to the support member 20. By setting the grip 10 as a grip rod 11, it is easier for the operator to grip the cleaning tool, thus facilitating the operation of the cleaning tool.

[0049] Combination Figure 1 As shown, an anti-slip sleeve 111 is provided at the end of the gripping rod 11 away from the carrier 20. By providing the anti-slip sleeve 111, the friction between the operator and the gripping rod 11 can be increased, which is beneficial for the operator to grip the gripping rod 11 and makes it less likely for the gripping rod 11 to fall out of the hand.

[0050] Combination Figure 1 As shown, the grip 10 also includes a connecting plate 12, which is connected to the end of the grip rod 11 near the support member 20. The connecting plate 12 is connected to the support member 20. With the above design, by setting the connecting plate 12, it is beneficial to the connection between the grip rod 11 and the support member 20, thereby increasing the connection strength between the grip rod 11 and the support member 20.

[0051] In some embodiments, the connecting plate 12 is connected to the carrier 20 by means of screws.

[0052] Using the cleaning tool described in this application, when performing turnout inspection work during comprehensive maintenance of railway lines, the operator can hold the cleaning tool with one hand to quickly clean the surface attachments such as sand, gravel, and oil stains on the frog rail, making it easier to detect damage and defects in this part in a timely manner, ensuring the quality of turnout operation and guaranteeing the safety of the line.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
