Description

Technical Field

[0001] This utility model relates to the field of maintenance equipment technology, and more specifically, to a maintenance tool. Background Technology

[0002] In powder production, fans and conveyor chains are used. During fan maintenance, gaskets need to be installed at the connections between different parts of the fan. To allow bolts to pass through the gaskets, holes need to be made in them. Conveyor chains require regular maintenance during use, such as disassembly for cleaning or replacement. Because the connecting shafts between adjacent chain sections are tightly connected, disassembling the connecting shafts can be difficult.

[0003] In the existing technology, different tools are required when it is necessary to make an opening and disassemble the connecting shaft. For example, a drill bit can be used to make an opening, while a thin rod is needed to push the connecting shaft out when disassembling it. Utility Model Content

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0028] like Figure 1 and Figure 6 As shown, the maintenance tool of this embodiment is used for drilling and disassembling connecting shafts. The maintenance tool includes: a base 10, a first connecting mechanism 20, a driving device 30, and a pressure rod 40. The base 10 is provided with a clearance hole 11 and is used to support the part 1 to be drilled. The first connecting mechanism 20 is detachably mounted on the base 10. The driving device 30 is mounted on the first connecting mechanism 20 and located above the base 10. The pressure rod 40 is movably mounted on the driving device 30 along a height direction parallel to the base 10. The driving device 30 and the pressure rod 40 drive each other so that one end of the pressure rod 40 can move into the clearance hole 11. When the first connecting mechanism 20 is connected to the base 10, the pressure rod 40 can move into the clearance hole 11. When the first connecting mechanism 20 is separated from the base 10, the first connecting mechanism 20 engages with the part to be disassembled, and the pressure rod 40 can push out the connecting shaft of the part to be disassembled.

[0029] Applying the technical solution of this embodiment, the maintenance tool includes a base 10, a first connecting mechanism 20, a driving device 30, and a pressure rod 40. The pressure rod 40 can extend into the base 10 through the clearance hole 11, and thus, during the process of the pressure rod 40 extending into the base 10, the pressure rod 40 can drill a hole in the part 1 to be drilled. The first connecting mechanism 20 is detachably mounted on the base 10, so that the first connecting mechanism 20 can be separated from or connected to the base 10. When the first connecting mechanism 20 is connected to the base 10, the base 10 can support the part 1 to be drilled, facilitating the drilling by the pressure rod 40. When the first connecting mechanism 20 is separated from the base 10, the pressure rod 40 can contact the connecting shaft of the shaft to be disassembled, thereby pushing out the connecting shaft. That is, by making the first connecting mechanism 20 and the base 10 detachable, the maintenance tool can be used for both drilling and disassembling the connecting shaft, making the maintenance tool more versatile. The driving device 30 can drive the pressure rod 40 to move in a height direction parallel to the base 10, thereby enabling the pressure rod 40 to drill a hole in the part 1 to be drilled, or to push out the connecting shaft. Therefore, the technical solution of this embodiment effectively solves the problem of poor versatility of maintenance tools in the prior art.

[0030] It should be noted that the part to be punched 1 can be a sealing gasket, cardboard, or other objects. The shaft to be disassembled refers to the connection between two structures via a connecting shaft, which can be a plate chain.

[0031] like Figure 1As shown, in this embodiment, the base 10 includes a first mounting plate 12 and a support base 13. A clearance hole 11 is provided on the support base 13. A first end of the first mounting plate 12 is connected to the support base 13, and a second end of the first mounting plate 12 protrudes outward from the support base 13. A first connecting mechanism 20 is provided at the second end of the first mounting plate 12 and is detachably connected to the first mounting plate 12. The first mounting plate 12 connects the support base 13 and the first connecting mechanism 20, ensuring a stable relative position between the first connecting mechanism 20 and the support base 13, facilitating the opening of the pressure rod 40. The outward protrusion of the second end of the first mounting plate 12 makes the connection between the first connecting mechanism 20 and the base 10 more convenient. The detachable connection between the first connecting mechanism 20 and the first mounting plate 12 allows for the connection or separation of the first connecting mechanism 20 from the base 10.

[0032] like Figure 1 and Figure 3 As shown, in this embodiment, the support base 13 includes a first base 131 and a second base 132. The first base 131 is connected to the first connecting mechanism 20. The second base 132 is rotatably mounted on the first base 131. Multiple clearance holes 11 are provided, each with a different diameter, and are spaced apart along the circumferential direction of the second base 132. The pressure rod 40 includes a rod 41 and multiple pressure heads 42. The rod 41 is movably mounted on the driving device 30. One of the multiple pressure heads 42 is selectively connected to the rod 41, and each pressure head 42 has a different diameter. When the second base 132 rotates relative to the first base 131, the position of the multiple clearance holes 11 on the second base 132 relative to the pressure rod 40 changes, thereby changing the diameter of the clearance hole 11 located below the pressure rod 40 and allowing for the replacement of pressure heads 42 with different diameters, thus enabling the fabrication of holes with different diameters.

[0033] It should be noted that the pressure head 42 and the rod body 41 are connected by threads.

[0034] like Figure 3 As shown, in this embodiment, the first seat 131 includes a mounting shaft 1311, and the second seat 132 includes a mounting cylinder 1321, with the mounting shaft 1311 passing through the mounting cylinder 1321. The mounting shaft 1311 and the mounting cylinder 1321 facilitate the connection between the first seat 131 and the second seat 132. When the mounting cylinder 1321 rotates relative to the mounting shaft 1311, it has a damped feel; that is, the rotation of the mounting cylinder 1321 relative to the mounting shaft 1311 requires the application of a certain amount of operating force.

[0035] It should be noted that the second base 132 also includes a support plate, which is located at the end of the mounting cylinder 1321 away from the first base 131, and the clearance hole 11 is located on the support plate.

[0036] Specifically, the diameter of the support plate is larger than the diameter of the mounting cylinder 1321, and multiple clearance holes 11 are arranged around the outer periphery of the mounting cylinder 1321.

[0037] In other embodiments, the second seat 132 includes a mounting shaft 1311, and the first seat 131 includes a mounting cylinder 1321.

[0038] like Figure 1 and Figure 3 As shown, in this embodiment, a first threaded structure is provided on the outer surface of the mounting shaft 1311, and a second threaded structure is provided on the inner wall of the mounting cylinder 1321. The first threaded structure and the second threaded structure are threadedly engaged. The provision of the first threaded structure and the second threaded structure facilitates the connection between the mounting shaft 1311 and the mounting cylinder 1321.

[0039] In other embodiments, the first threaded structure may not be provided on the outer surface of the mounting shaft 1311, and the second threaded structure may not be provided on the inner wall of the mounting cylinder 1321.

[0040] like Figure 2 As shown, in this embodiment, the base 10 further includes a first fixing member 14. A first connecting hole is provided on the first mounting plate 12, and the first fixing member 14 passes through the first connecting hole. One end of the first fixing member 14 is provided with a stop head 141 that cooperates with the stop of the first mounting plate 12, and the other end of the first fixing member 14 is connected to the support base 13. The first fixing member 14 can fix the first mounting plate 12 to the support base 13. The stop head 141 cooperates with the stop of the first mounting plate 12, preventing the end of the first fixing member 14 away from the support base 13 from completely passing through the first connecting hole.

[0041] like Figure 1 and Figure 4 As shown, in this embodiment, the first connecting mechanism 20 includes a first connecting rod 21 and a clamping structure 22. The first end of the first connecting rod 21 is connected to the first mounting plate 12, and the clamping structure 22 is disposed at the second end of the first connecting rod 21. The driving device 30 includes a second mounting plate 31 and a pushing mechanism 32. The second mounting plate 31 is clamped within the clamping structure 22, and the pushing mechanism 32 is disposed on the second mounting plate 31. The pushing mechanism 32 drives the pressure rod 40. The clamping structure 22 can fix the second mounting plate 31, thereby keeping the relative position of the second mounting plate 31 and the base 10 unchanged. The pushing mechanism 32 can push the pressure rod 40 to move.

[0042] It should be noted that the propulsion mechanism 32 includes a fixed frame, a stationary handle, an operating handle, a push plate, a stop plate, a locking plate, a first elastic element, and a second elastic element. The fixed frame is mounted on the second mounting plate 31, the stationary handle is mounted on the fixed frame, the middle part of the operating handle is hinged to the fixed frame, the first end of the push plate is hinged to the first end of the operating handle, the second end of the operating handle is the operating end, the first elastic element is located between the push plate and the second mounting plate 31, the second elastic element is located between the top of the fixed frame and the stop plate, the locking plate is located on the top of the fixed frame, and the locking plate and the second elastic element are spaced apart. A locking block is provided at the end of the locking plate away from the fixed frame, and a locking groove is provided at the end of the stop plate connected to the locking plate, with the locking block and the locking groove providing a stop. A first clearance hole is provided on the push plate, a second clearance hole is provided on the stop plate, and a third clearance hole is provided on the top of the fixed frame. The pressure rod passes through the second clearance hole, the second elastic element, the third clearance hole, the first clearance hole, and the first elastic element.

[0043] Both the first and second elastic elements are springs.

[0044] Pressing the operating handle moves the push plate, which in turn moves the pressure rod, causing the bottom end of the pressure rod to move away from the second mounting plate 31. When the bottom end of the push rod moves closer to the second mounting plate 31, pressing the stop plate in that direction allows the pressure rod to slide smoothly within the second clearance hole, thus moving the bottom end of the pressure rod closer to the second mounting plate.

[0045] The second mounting plate 31 is provided with a fourth clearance hole, and the pressure rod 40 passes through the fourth clearance hole.

[0046] like Figure 5 As shown, in this embodiment, the clamp structure 22 includes a first arc-shaped member 221 and a second arc-shaped member 222 that are mated together. The first end of the first arc-shaped member 221 and the first end of the second arc-shaped member 222 are hinged together. A locking mechanism is provided between the second end of the first arc-shaped member 221 and the second end of the second arc-shaped member 222. The first connecting rod 21 is connected to the first arc-shaped member 221. The first connecting mechanism 20 also includes a second connecting rod 23. The first connecting rod 21 and the second connecting rod 23 are spaced apart and parallel to each other. The first end of the second connecting rod 23 is connected to the first mounting plate 12, and the second end of the second connecting rod 23 is connected to the second arc-shaped member 222. The hinged connection between the first end of the first arc-shaped member 221 and the first end of the second arc-shaped member 222 facilitates the clamping of the second mounting plate 31 by the first arc-shaped member 221 and the second arc-shaped member 222. The locking mechanism can connect the second end of the first arc-shaped member 221 and the second end of the second arc-shaped member 222, so that the relative position between the first arc-shaped member 221 and the second arc-shaped member 222 remains unchanged, thereby fixing the second mounting plate 31 between the first arc-shaped member 221 and the second arc-shaped member 222.

[0047] It should be noted that the locking mechanism can be a screw and nut, or it can be a snap-fit ​​and a slot.

[0048] When using maintenance tools to disassemble the connecting shaft, the shaft to be disassembled can be placed on the first connecting rod 21 and the second connecting rod 23, which makes the relative position between the maintenance tools and the shaft to be disassembled more stable.

[0049] like Figure 2 As shown, in this embodiment, the first mounting plate 12 is provided with a second connecting hole 121. The maintenance tool also includes a second fixing member 50. The first end of the first connecting rod 21 passes through the second connecting hole 121 and is provided with a stop flange 211 that cooperates with the stop of the first mounting plate 12. The second fixing member 50 is detachably provided at the end of the first end of the first connecting rod 21. The first mounting plate 12 is sandwiched between the stop flange 211 and the second fixing member 50. The second connecting hole 121 allows the first connecting rod 21 to pass through the first mounting plate 12, thereby allowing the second fixing member 50 to connect with the first connecting rod 21. The stop flange 211 and the second fixing member 50 can clamp the first mounting plate 12, so that the relative position between the first connecting rod 21 and the first mounting plate 12 remains unchanged.

[0050] The first mounting plate 12 is also provided with a third connecting hole. The maintenance tool also includes a third fixing member. The first end of the second connecting rod 23 passes through the third connecting hole and is provided with a baffle that cooperates with the stop of the first mounting plate 12. The third fixing member is detachably provided at the end of the first end of the second connecting rod 23. The first mounting plate 12 is sandwiched between the baffle and the third fixing member.

[0051] like Figure 1 and Figure 3 As shown, in this embodiment, the maintenance tool further includes a pressing and fixing member 60. The pressing and fixing member 60 includes a second connecting mechanism 61 and a clamping member 62. The second connecting mechanism 61 is disposed on the base 10, and the clamping member 62 is located above the base 10. The clamping member 62 is movably disposed on the second connecting mechanism 61 along the height direction of the base 10 to press the part to be punched 1 onto the base 10. The clamping member 62 can move along the height direction of the base 10, and thus the clamping member 62 can move toward the base 10, thereby pressing the part to be punched 1 onto the base 10, so that the relative position between the part to be punched 1 and the base 10 remains unchanged.

[0052] It should be noted that the second connecting mechanism 61 includes a connecting ring and a connecting frame. The connecting ring is sleeved on the outer periphery of the first base 131 or the second base 132, and the connecting frame is disposed on the connecting ring, with the top of the connecting frame located above the base 10.

[0053] The connecting frame is provided with threaded mounting holes, and the clamping element is a screw, which is threadedly engaged with the threaded mounting holes.

[0054] When the connecting ring is located on the outer periphery of the second seat 132, the rotation between the connecting ring and the second seat 132 is damped. The inner wall of the connecting ring is threadedly engaged with the outer periphery of the second seat 132, so that after the second seat 132 rotates relative to the first seat 131, the connecting ring can rotate relative to the second seat 132, thus avoiding interference between the connecting ring and the first connecting mechanism 20.

[0055] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms 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 limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0056] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0057] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
