Description

Technical Field

[0001] This application relates to the field of repair equipment technology, and in particular to repair tools and repair equipment. Background Technology

[0002] During maintenance and other operations, railway signaling equipment often requires the removal and installation of nuts using sockets. However, railway signaling equipment uses different types of nuts, each with different dimensions. Workers must carry sockets of various sizes, increasing their workload. Furthermore, in some situations, the nut is located in poor lighting, making it difficult for workers to quickly and accurately align the socket, requiring multiple attempts and reducing work efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a maintenance tool and device to address the problem of high workload and low efficiency of workers during the process of disassembling and assembling nuts.

[0004] A repair tool, comprising:

[0005] Multiple sleeves are coaxially and sequentially fitted together. Adjacent sleeves can slide relative to each other along the axial direction. The axial dimension of the inner sleeve is smaller than that of the outer sleeve. Each sleeve has a disassembly port. The axial cross-sectional area of ​​the inner disassembly port is smaller than that of the outer disassembly port. The disassembly port is used to connect with a nut.

[0006] An illumination assembly is disposed inside the sleeve and faces the disassembly port to provide illumination to the disassembly port.

[0007] In one embodiment, the lighting component includes:

[0008] The lighting unit is located inside the innermost sleeve to provide illumination to the innermost disassembly port;

[0009] The control unit is located on the outer side wall of the outermost sleeve. The control unit is connected in communication with the lighting unit to control the switching of the lighting unit.

[0010] In one embodiment, the repair tool further includes:

[0011] An elastic element is disposed between two adjacent sleeves to drive the inner sleeve to move toward the disassembly port of the outer sleeve.

[0012] In one embodiment, the repair tools include:

[0013] The first sleeve has a first receiving cavity and a first disassembly port that are in communication with each other;

[0014] The second sleeve is disposed in the first receiving cavity. One end of the second sleeve has a second disassembly port, the axial cross-sectional area of ​​the second disassembly port is smaller than the axial cross-sectional area of ​​the first disassembly port, and the other end of the second sleeve has a first sealing element.

[0015] A first elastic element is disposed between a first sleeve and a second sleeve. One end of the first elastic element abuts against the inner wall of the first receiving cavity, and the other end of the first elastic element abuts against the first sealing element, so as to drive the second sleeve to move toward the first disassembly port.

[0016] In one embodiment, the lighting assembly includes a control unit, and the first sleeve includes;

[0017] The main body has a first receiving cavity and a first disassembly port;

[0018] A connecting part is provided at the end of the main body that is away from the first disassembly port, and a control unit is provided on the connecting part.

[0019] In one embodiment, the repair tool further includes:

[0020] A magnetic suction assembly is provided on the connecting part to magnetically fix the first sleeve.

[0021] In one embodiment, the first sleeve and the second sleeve have a first snap-fit ​​structure to guide the relative sliding of the first sleeve and the second sleeve in the axial direction.

[0022] In one embodiment, the first snap-fit ​​structure includes:

[0023] The first slot is provided on the inner wall of the first receiving cavity, and the length of the first slot extends along the axial direction of the first sleeve.

[0024] The first protrusion is located on the outer side wall of the second sleeve and is located within the first slot.

[0025] In one embodiment, the second sleeve has a second receiving cavity communicating with a second disassembly port, and the maintenance tool further includes:

[0026] The third sleeve is disposed in the second receiving cavity. The third sleeve has a third receiving cavity and a third disassembly port that are interconnected. The lighting component is disposed in the third receiving cavity to provide light to the third disassembly port. The axial cross-sectional area of ​​the third disassembly port is smaller than that of the second disassembly port. The end of the third sleeve away from the third disassembly port has a second sealing element.

[0027] The second elastic element is disposed between the second sleeve and the third sleeve. One end of the second elastic element abuts against the inner wall of the second receiving cavity, and the other end of the second elastic element abuts against the second sealing element, so as to drive the third sleeve to move toward the direction of the second disassembly port.

[0028] A repair device includes a drive mechanism and the repair tool provided above. The drive mechanism is driven to drive a plurality of sleeves to rotate.

[0029] The aforementioned repair tool features multiple sleeves coaxially nested together. The inner sleeve is slidably positioned relative to the outer sleeve. Different sleeves have different cross-sectional areas for their disassembly ports, allowing them to connect to different nut sizes for disassembly and assembly. Furthermore, an illumination component is installed within each sleeve to provide light to the disassembly port. This structure allows multiple sleeves to accommodate nuts of various sizes, enabling the repair tool to disassemble nuts of different dimensions. When disassembling the smallest nut, the disassembly port of the innermost sleeve connects to that nut. When disassembling nuts of other sizes, the nut connects to the disassembly port of the corresponding sleeve, and the inner sleeve of that sleeve is pressed into the interior of the sleeve by the nut, preventing interference between the inner sleeve and the nut. Simultaneously, because the axial dimension of the inner sleeve is smaller than that of the outer sleeve, after the inner sleeve is pressed into the outer sleeve, the outer sleeve has sufficient space to connect with the nut. This design eliminates the need for workers to carry multiple individual sockets of different sizes, saving time spent searching for and replacing them during operations. The maintenance tools can quickly adapt to various nut sizes, reducing the workload for workers. Furthermore, the lighting unit provides illumination to the disassembly port, thereby brightening the work area and mitigating the difficulty of nut positioning in dim lighting conditions. The light is projected from inside the socket onto the nut surface, reducing shadows, allowing workers to clearly observe the relative position of the socket's disassembly port and the nut, enabling quick and accurate alignment. This reduces the number of attempts required, improves work efficiency, and lowers the difficulty of the task. Attached Figure Description

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] See Figure 1 and Figure 2 One embodiment of this application provides a repair tool, which includes a plurality of sleeves 110 and a lighting assembly 120. The plurality of sleeves 110 are coaxially and sequentially sleeved, with adjacent sleeves 110 capable of sliding relative to each other along the axial direction. The axial dimension of the inner sleeve 110 is smaller than that of the outer sleeve 110. Each sleeve 110 has a disassembly port 111, the cross-sectional area of ​​which is smaller along the axial direction than that of the outer disassembly port 111. The disassembly port 111 is used for connection with a nut. The lighting assembly 120 is disposed within the sleeve 110 and faces the disassembly port 111 to provide illumination to the disassembly port 111. (See also...) Figure 1 The X direction is the axial direction of sleeve 110.

[0060] Using the technical solution of this application, multiple sleeves 110 are coaxially and sequentially sleeved. The inner sleeve 110 is slidably disposed relative to the outer sleeve 110. The disassembly ports 111 of different sleeves 110 have different cross-sectional areas, meaning that the disassembly ports 111 of different sleeves 110 can connect to different types of nuts for disassembling and assembling different types of nuts. Furthermore, an illumination component 120 is provided inside the sleeve 110, which can provide illumination to the disassembly ports 111. With the above structure, multiple sleeves 110 correspond to nuts of various sizes, meaning that the maintenance tool can disassemble multiple nuts of different sizes. When disassembling the smallest nut, the disassembly port 111 of the innermost sleeve 110 connects to that nut; when disassembling nuts of other sizes, the nut connects to the disassembly port 111 of the corresponding sleeve 110. The inner sleeve 110 of the sleeve 110 is pressed and moved into the interior of the sleeve 110 by the nut, avoiding interference between the inner sleeve 110 and the nut. Meanwhile, because the axial dimension of the inner sleeve 110 is smaller than that of the outer sleeve 110, the outer sleeve 110 has sufficient space to connect with the nut after being squeezed into it. This design eliminates the need for workers to carry multiple individual sleeves 110 of different sizes, saving time spent searching for and replacing them during operation. Maintenance tools can quickly adapt to nuts of various sizes, reducing the workload for workers. Furthermore, the lighting assembly 120 provides illumination to the disassembly port 111, thereby illuminating the work area and reducing the difficulty of nut positioning in dim lighting conditions. The light is projected from inside the sleeve 110 onto the nut surface, reducing shadows. Workers can clearly observe the relative position of the disassembly port 111 of the sleeve 110 and the nut, achieving quick and accurate alignment, reducing the number of attempts, improving work efficiency, and lowering the difficulty of the task.

[0061] Furthermore, the above structure can reduce the size of maintenance tools, making them easier for staff to carry, and also reducing the limitations of maintenance work in confined spaces.

[0062] See Figure 1 The lighting assembly 120 includes a lighting unit 121 and a control unit 122. The lighting unit 121 is disposed within the innermost sleeve 110 to provide illumination to the innermost disassembly port 111. The control unit 122 is disposed on the outermost wall of the outermost sleeve 110 and is communicatively connected to the lighting unit 121 to control the switching of the lighting unit 121. This arrangement, with the control unit 122 located on the outermost wall of the outermost sleeve 110, facilitates operation by the worker and reduces operational difficulty. The lighting unit 121, located within the innermost sleeve 110, minimizes light obstruction from other sleeve structures, ensuring the illumination range of the lighting unit 121.

[0063] In some embodiments, the lighting unit 121 is an LED light-emitting diode.

[0064] In some embodiments, the lighting assembly 120 further includes a transmission unit 123, which is electrically connected to the lighting unit 121 and the control unit 122. This configuration makes the various units of the lighting assembly 120 readily available, reducing the production cost of the lighting assembly 120.

[0065] See Figure 1 The maintenance tool also includes an elastic element 130, which is disposed between two adjacent sleeves 110 to drive the inner sleeve 110 to move toward the disassembly port 111 of the outer sleeve 110. With this configuration, when the inner sleeve 110 moves under pressure, it can automatically move toward the disassembly port 111 of the outer sleeve 110 when the external force is removed. The inner sleeve 110 can automatically return to its initial position where it can connect with the corresponding nut, eliminating the need for manual adjustment and improving the automation level of the maintenance tool.

[0066] In some embodiments, the elastic element 130 is a spring.

[0067] See Figures 3 to 6 The maintenance tool includes a first sleeve 141, a second sleeve 142, and a first elastic element 151. The first sleeve 141 has a first receiving cavity 1411 and a first disassembly port 1412 that are in communication with each other. The second sleeve 142 is disposed within the first receiving cavity 1411. One end of the second sleeve 142 has a second disassembly port 1421, the axial cross-sectional area S2 of the second disassembly port 1421 being smaller than the axial cross-sectional area S1 of the first disassembly port 1412. The other end of the second sleeve 142 has a first sealing element 1422. The first elastic element 151 is disposed between the first sleeve 141 and the second sleeve 142. One end of the first elastic element 151 abuts against the inner wall of the first receiving cavity 1411, and the other end of the first elastic element 151 abuts against the first sealing element 1422, thereby driving the second sleeve 142 to move towards the first disassembly port 1412. For ease of description, the first sleeve 141 is capable of removing the first nut, and the second sleeve 142 is capable of removing the second nut. The size of the first nut is larger than that of the second nut. With this configuration, when the second nut is removed, the second removal port 1421 connects to the second nut; when the first nut is removed, the first nut connects to the first removal port 1412, and the second sleeve 142 is pressed and moved into the first receiving cavity 1411 by the first nut, avoiding interference between the second sleeve 142 and the first nut. After the second sleeve 142 has moved under pressure, the first elastic element 151 can drive the second sleeve 142 towards the first removal port 1412 when the external force disappears, and the second sleeve 142 automatically returns to its initial position where it can connect with the second nut.

[0068] In some embodiments, the first disassembly port 1412 and the second disassembly port 1421 are hexagonal structures, with the width of opposite sides of the first disassembly port 1412 being 10 mm and the width of opposite sides of the second disassembly port 1421 being 8 mm.

[0069] See Figure 3 The lighting assembly 120 includes a control unit 122. The first sleeve 141 includes a body portion 1413 and a connecting portion 1414. The body portion 1413 has a first receiving cavity 1411 and a first disassembly port 1412. The connecting portion 1414 is located at the end of the body portion 1413 away from the first disassembly port 1412, and the control unit 122 is located on the connecting portion 1414. This arrangement facilitates connection of the connecting portion 1414 to other structures. Furthermore, the control unit 122 is located away from the disassembly port 1411, reducing the possibility of contamination, facilitating operation, and minimizing the possibility of impact between the control unit 122 and structures such as nuts, thus extending the service life of the lighting assembly 120.

[0070] See Figure 3 The maintenance tools also include a magnetic attachment component 160, which is disposed on the connecting part 1414 to magnetically fix the first sleeve 141. With this configuration, the magnetic attachment component 160 can magnetically attach the maintenance tools to surrounding metal equipment, such as cabinet doors, outdoor switches, track circuits, signal lights, and bridges, improving the portability of the maintenance tools and reducing the possibility of loss after handling, making it easier for staff to retrieve and place them.

[0071] participate Figure 7 A first engaging structure 143 is provided between the first sleeve 141 and the second sleeve 142 to guide the relative sliding of the first sleeve 141 and the second sleeve 142 along the axial direction. This arrangement improves the stability of the second sleeve 142 when moving relative to the first sleeve 141, preventing tilting, and also prevents relative rotation between the first sleeve 141 and the second sleeve 142. This eliminates the shaking and impact caused by torque between the first sleeve 141 and the second sleeve 142, improves the stability of the maintenance tool under stress, and extends the service life of the maintenance tool.

[0072] participate Figure 7The first snap-fit ​​structure 143 includes a first slot 1431 and a first protrusion 1432. The first slot 1431 is disposed on the inner wall of the first receiving cavity 1411, and the length of the first slot 1431 extends along the axial direction of the first sleeve 141. The first protrusion 1432 is disposed on the outer wall of the second sleeve 142, and the first protrusion 1432 is disposed within the first slot 1431. This arrangement facilitates the processing of the first sleeve 141 and the second sleeve 142, resulting in a simple structure and convenient operation. Simultaneously, the first snap-fit ​​structure 143 guides the second sleeve 142 during axial movement, improving the stability of the second sleeve 142's movement.

[0073] In some embodiments, the first sleeve 141 and the second sleeve 142 may have a plurality of first snap-fit ​​structures 143.

[0074] See Figure 3 , Figure 6 and Figure 8 The second sleeve 142 has a second receiving cavity 1423, which communicates with the second disassembly port 1421. The maintenance tool also includes a third sleeve 144 and a second elastic element 152. The third sleeve 144 is disposed within the second receiving cavity 1423 and has a third receiving cavity 1441 and a third disassembly port 1442 that communicate with each other. An illumination assembly 120 is disposed within the third receiving cavity 1441 to provide illumination to the third disassembly port 1442. The axial cross-sectional area S3 of the third disassembly port 1442 is smaller than the axial cross-sectional area S2 of the second disassembly port 1421. The end of the third sleeve 144 away from the third disassembly port 1442 has a second sealing element 1443. The second elastic element 152 is disposed between the second sleeve 142 and the third sleeve 144. One end of the second elastic element 152 abuts against the inner wall of the second receiving cavity 1423, and the other end abuts against the second sealing element 1443, thereby driving the third sleeve 144 to move towards the second disassembly port 1421. For ease of description, the third sleeve 144 is capable of disassembling the third nut, and the size of the second nut is larger than that of the third nut. With this configuration, when the third nut is disassembled, the third disassembly port 1442 connects to the third nut; when the second nut is disassembled, the second nut connects to the second disassembly port 1421, and the third sleeve 144 is pressed and moved into the second receiving cavity 1423 by the second nut, avoiding interference between the third sleeve 144 and the second nut. After the third sleeve 144 moves under pressure, the second elastic element can drive the third sleeve 144 to move towards the second disassembly port 1421 when the external force disappears, and the third sleeve 144 automatically returns to its initial position where it can connect with the third nut.

[0075] In some embodiments, the third disassembly port 1442 has a hexagonal structure and the width of opposite sides of the third disassembly port 1442 is 6mm.

[0076] participate Figure 7 A second engaging structure 145 is provided between the second sleeve 142 and the third sleeve 144 to guide the relative sliding of the third sleeve 144 and the second sleeve 142 along the axial direction. This arrangement improves the stability of the third sleeve 144 when moving relative to the second sleeve 142, preventing tilting, and also prevents relative rotation between the third sleeve 144 and the second sleeve 142. This eliminates the shaking and impact caused by torque between the third sleeve 144 and the second sleeve 142, improves the stability of the maintenance tool under stress, and extends the service life of the maintenance tool 100.

[0077] See Figure 7 The second snap-fit ​​structure 145 includes a second slot 1451 and a second protrusion 1452. The second slot 1451 is disposed on the inner wall of the second receiving cavity 1423, and its length extends axially along the second sleeve 142. The second protrusion 1452 is disposed on the outer wall of the third sleeve 144, and is located within the second slot 1451. This arrangement facilitates the processing of the third sleeve 144 and the second sleeve 142, resulting in a simple structure and convenient operation. Simultaneously, the second snap-fit ​​structure 145 guides the third sleeve 144 during axial movement, improving the stability of its movement.

[0078] See Figure 9 Another embodiment of this application provides a maintenance device, which includes a drive mechanism 200 and the aforementioned maintenance tool 100. The drive mechanism 200 is driven to the maintenance tool 100 to drive a plurality of sleeves 110 to rotate. This configuration can improve the automation level of the maintenance device and reduce the workload of workers.

[0079] In some embodiments, the drive mechanism 200 is an electric mechanism, a pneumatic mechanism, or a ratchet mechanism. The drive mechanism 200 is a mature technology in related fields and will not be described in detail here.

[0080] In some embodiments, the maintenance device further includes a fixing mechanism 300, one end of which is fixedly connected to the drive mechanism 200, and the other end of which is fitted onto the worker's wrist. This configuration prevents the maintenance device from falling from a height and protects the safety of other workers.

[0081] In some embodiments, the fixing mechanism 300 is a fall arrest rope.

[0082] 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.

[0083] 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.
