Description

Technical Field

[0001] This utility model relates to the field of connecting pin disassembly technology, and in particular to a device for disassembling connecting pins from their objects. Background Technology

[0002] In the field of machinery, many pieces of equipment use connecting pins to fix various components together, thereby enabling the normal operation of the equipment. However, when it is necessary to disassemble the equipment, the connecting pins need to be disengaged from the equipment to allow for disassembly.

[0003] In existing technology, when it is necessary to disengage the connecting pin from the equipment, a jack is generally used to hold the connecting pin from bottom to top, and the connecting pin is pushed out by operating the jack.

[0004] While this method can disconnect the connecting pin from the equipment, it often encounters difficulties during use, such as the erection of the jack. During the erection process, the location used to support the jack is often uneven, requiring the use of auxiliary tools to erect the jack, which is inconvenient.

[0005] At the same time, due to the limited stroke of the jack, when lifting the connecting pin, after the jack reaches its stroke limit, a pad needs to be added for the next lifting, and so on until the connecting pin is lifted out, which is a cumbersome operation.

[0006] Furthermore, in this method, during the process of lifting the connecting pin, the component fixed to the connecting pin will generally move along with the connecting pin. At this point, it is necessary to hammer the object fixed by the connecting pin to disengage the connecting pin from the object, and the hammering process will cause some damage to the object. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a device for removing connecting pins from their objects. To achieve the above objective, this utility model adopts the following technical solution:

[0008] A device for removing a connecting pin from an object of use, the object comprising a first connecting plate having a first through hole, and a second connecting plate fitted to the first connecting plate and having a second through hole, the first and second through holes corresponding to each other, for providing a connecting pin that allows the first and second connecting plates to be fixed together relative to each other.

[0009] The device includes a fixing part that is fixed relative to the object being used, a support part that is disposed opposite to the fixing part, and an adjustment part that is connected to the fixing part. The adjustment part passes through the support part and allows the support part to move along a path formed by the adjustment part to adjust the relative distance between the support part and the fixing part.

[0010] The adjustment section is also provided with a limiting section that selectively limits the support section, and the support section is also provided with an ejector section that selectively extends. The force output end of the ejector section is configured to allow it to abut against the connecting pin in order to drive the connecting pin to move.

[0011] Furthermore, the fixing part includes a force-applying member for abutting against the upper surface of the object being used, and a connecting member connected to the force-applying member and extending downward.

[0012] Furthermore, the adjusting part includes a threaded rod that is fixed to the connecting member and extends downward. The threaded rod passes through the support part, and a limiting part is provided at the free end of the threaded rod and configured to allow rotation along the threaded rod to adjust the relative distance between the support part and the force-applying member, and to limit the downward movement of the support part after adjustment.

[0013] Furthermore, the adjustment part also includes a transition piece disposed between the connector and the threaded rod, and fixedly connected to the connector and the threaded rod respectively. The radially inner side of the transition piece is smooth to allow the objects to abut against each other.

[0014] Furthermore, the support includes a support plate with a flat upper surface and a mounting opening disposed on the support plate and extending through the support plate, the mounting opening being used to provide a channel through which the threaded rod passes.

[0015] Furthermore, the fixing part, adjusting part, and mounting port are arranged in two sets in a corresponding manner, and the two adjusting parts are connected to the limiting part after passing through the mounting port.

[0016] Furthermore, the two mounting ports extend radially inward and are interconnected to form a space for the radial movement of the adjustment part, thereby adjusting the relative distance between the two fixed parts.

[0017] Furthermore, two limiting parts are provided on each of the adjustment parts, and the two limiting parts allow the downward movement of the support part to be restricted.

[0018] Furthermore, the radial length of the force-applying member is less than the radial length between the side of the first connecting plate and the connecting pin.

[0019] Furthermore, the ejector section is configured as a jack.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This device is provided with a fixing part that is relatively fixed to the object being used and a support part that corresponds to the fixing part, so that the fixing part and the support part together form a space for placing the ejector part, and the ejector part can be placed on the support part. This facilitates the installation of the ejector part.

[0022] At the same time, since the user object is fixed to the fixing part, when the ejector part applies force to the connecting pin, the fixing part can limit the user object, thereby preventing the user object and the connecting pin from moving together.

[0023] 2. This device also includes a support portion disposed opposite to the fixed portion, and an adjustment portion connected to the fixed portion. The adjustment portion passes through the support portion and allows the support portion to move along a path formed by the adjustment portion to adjust the relative distance between the support portion and the fixed portion. The adjustment portion also includes a limiting portion for selectively limiting the support portion. With this configuration, the relative distance between the support portion and the fixed portion can be adjusted, and the limiting portion can limit the support portion after adjustment. Therefore, the relative distance between the support portion and the fixed portion can be adjusted according to the stroke of the ejector portion. Attached Figure Description

Detailed Implementation

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0029] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a device for removing a connecting pin from its object of use.

[0030] For convenience, the direction parallel to the support plate will be referred to as "radial" or "horizontal", the direction perpendicular to the "radial" will be referred to as "vertical" or "vertical direction", the direction of movement towards the fixed part in the "vertical" direction will be referred to as "upward movement" or "downward movement" or "downward movement".

[0031] like Figure 1 As shown, the application object 100 typically includes a first connecting plate 10 with a first through hole 101 and a second connecting plate 20 with a second through hole 201. The first connecting plate 10 and the second connecting plate 20 are fitted together and the first through hole 101 and the second through hole 201 correspond to each other, so as to provide a connecting pin 30 that allows the first connecting plate 10 and the second connecting plate 20 to be fixed together.

[0032] In this configuration, the connecting pin 30 can fix the first connecting plate 10 and the second connecting plate 20 together, thereby making the first connecting plate 10 and the second connecting plate 20 form a whole.

[0033] Figure 1 , 2 The illustration schematically shows a device according to the present invention for removing a connecting pin from its object of use. In such a way... Figure 1 In the embodiment shown, the device for removing the connecting pin 30 from its user object 100 includes a fixing part 1 that is fixed relative to the user object 100, a support part 2 that is disposed opposite to the fixing part 1, and an adjustment part 3 that is connected to the fixing part 1.

[0034] In this embodiment, as Figure 1 As shown, the adjustment part 3 passes through the support part 2 and allows the support part 2 to move along the path formed by the adjustment part 3. In this way, the relative distance between the support part 2 and the fixed part 1 can be adjusted as the support part 2 moves along the adjustment part 3.

[0035] Meanwhile, in the illustrated embodiment, as Figure 1 As shown, a limiting part 31 is also provided on the adjusting part 3. The limiting part 31 is located below the supporting part 2 and is configured to selectively limit the supporting part 2. In addition, an ejector part 4 is selectively provided on the supporting part 2. The force output end 41 of the ejector part 4 is configured to allow it to abut against the connecting pin 30 to drive the connecting pin 30 to move.

[0036] It should be noted that the force output end 41 of the ejector 4 is configured to allow movement along the axial direction of the ejector 4, so as to apply a force along the axial direction of the ejector 4 to the connecting pin 30, thereby driving the connecting pin 30 to move.

[0037] In this configuration, when it is necessary to remove the connecting pin 30 from its user object 100, the fixing part 1 and the adjusting part 3 are first fixed together, so that the fixing part 1 and the user object 100 are relatively fixed.

[0038] Simultaneously, a support part 2 is provided on the adjustment part 3, and the support part 2 is limited by the limiting part 31. In this way, the fixing part 1 and the support part 2 together form a space for placing the ejector part 4, and the ejector part 4 is placed in the space. Thus, the device is completed.

[0039] Then, the force output end 41 of the ejector 4 is brought into contact with the connecting pin 30. At this time, the ejector 4 is activated. During this process, the force output end 41 will continue to move along the ejector 4, thereby driving the connecting pin 30 to move until the connecting pin 30 disengages from the user object 100. Thus, the work of removing the connecting pin 30 from its user object 100 is completed.

[0040] However, when the force output end 41 moves to its limit and still cannot disengage the connecting pin 30 from the user object 100, the force output end 41 moves toward the ejector part 4, thereby retracting the ejector part 4. At the same time, a force is applied to the support part 2, causing the support part 2 to move along the adjustment part 3 until the force output end 41 abuts against the connecting pin 30 again.

[0041] At this time, the support part 2 is limited by the limiting part 31. Finally, the ejector part 4 is activated again. During this process, the force output end 41 will continue to move along the ejector part 4, thereby driving the connecting pin 30 to move until the connecting pin 30 is disengaged from the user object 100. In this way, the connecting pin 30 is removed from its user object 100.

[0042] In one embodiment, such as Figure 1 As shown, the fixing part 1 includes a force-applying member 11 for abutting against the upper surface of the user object 100, and a connecting member 12 connected to the force-applying member 11 and extending downward. Specifically, the fixing part 1 is configured in an "L" shape, such that the two right-angled sides formed by the fixing part 1 abut against the upper surface and side surface of the user object 100, respectively. Therefore, when the user object 100 receives an upward force, the fixing part 1 can be relatively fixed to the user object 100.

[0043] In one embodiment, such as Figure 1 , 2 As shown, the adjusting part 3 includes a threaded rod 32 that is fixed to the connecting member 12 and extends downward. In this embodiment, the threaded rod 32 is configured to pass through the support part 2. Meanwhile, the limiting part 31 is provided at the free end of the threaded rod 32 and is configured to allow rotation along the threaded rod 32 to adjust the relative distance between the support part 2 and the force-applying member 11. After the support part 2 is adjusted to its position, the limiting part 31 restricts the downward movement of the support part 2. This allows a stable space to be formed between the support part 2 and the force-applying member 11 for placing the ejector part 4, thereby enabling the ejector part 4 located within the space to stably apply force to the connecting pin 30.

[0044] According to a preferred embodiment of the present invention, such as Figure 1 , 2 As shown, the adjusting part 3 further includes a transition member 33 disposed between the connecting member 12 and the threaded rod 32, and fixedly connected to both the connecting member 12 and the threaded rod 32. In this embodiment, the radially inner side of the transition member 33 is smooth. In this way, when the transition member 33 abuts against the user object 100, the frictional force generated between the transition member 33 and the user object 100 can be reduced, thereby avoiding damage to the user object 100.

[0045] In one embodiment, such as Figure 2 As shown, the support portion 2 includes a support plate 21 with a flat upper surface and a mounting opening 22 disposed on and penetrating the support plate 21. In this embodiment, the mounting opening 22 is used to provide a channel through which the threaded rod 32 passes. In this way, the support portion 2 can be connected to the limiting portion 31 after passing through the mounting opening 22, thereby limiting the support portion 2 by the limiting portion 31.

[0046] According to a preferred embodiment of the present invention, such as Figure 1 , 2 As shown, the fixing part 1, adjusting part 3, and mounting port 22 are arranged in two sets in a corresponding manner. Specifically, two mounting ports 22 are provided on the support plate 21, and each adjusting part 3 connects to the limiting part 31 after passing through the mounting port 22, thereby limiting the downward movement of the support plate 21 by the limiting part 31.

[0047] In this way, the device can be stably connected to the user 100, thereby enabling the ejector 4 to stably apply force to the connecting pin 30.

[0048] In one embodiment, such as Figure 2As shown, each of the mounting ports 22 extends radially inward and is interconnected. In this way, the mounting ports 22 collectively form a space for the radial movement of the fixing part 1. This allows adjustment of the relative distance between the two fixing parts 1, enabling the device to operate on users 100 at different radial distances. Therefore, the applicability of the device 100 is improved.

[0049] According to a preferred embodiment of the present invention, such as Figure 1 , 2 As shown, two limiting parts 31 are provided on each of the fixed parts 1. In this way, the two limiting parts 31 on the fixed part 1 can restrict the downward movement of the support part 2, thereby further ensuring a stable connection between the support plate 21 and the adjustment part 3, and preventing the support plate 21 and the adjustment part 3 from separating from each other.

[0050] In one embodiment, such as Figure 1 , 2 As shown, the radial length of the force-applying member 11 is less than the radial length between the side plate of the first connecting plate 10 and the connecting pin 30. In this way, when the force-applying member 11 is positioned on the first connecting plate 10 in a corresponding manner, it can avoid interfering with the connecting pin 30 while the force-applying member 11 is in contact with the first connecting plate 10. Therefore, the connecting pin 30 can be prevented from being obstructed during movement.

[0051] In this embodiment, as Figure 1 , 2 As shown, the ejector part 4 is configured as a jack, and when the jack is mounted on the support part 2, its force output end 41 can abut against the connecting pin 30. This allows the force of the jack to be transmitted along the force output end 41 to the connecting pin 30, thereby driving the connecting pin 30 to move and disengaging it from the user object 100.

[0052] The operation of the device for removing the connecting pin 30 from its user object 100 according to the present invention is as follows.

[0053] First, the fixing part 1, the transition part 33, and the threaded rod 32 are fixedly connected together in sequence, so that the two right-angled sides formed by the fixing part 1 abut against the upper surface and the side surface of the user object 100 respectively.

[0054] Simultaneously, a support plate 21 is inserted through the mounting opening 22 along the threaded rod 32, and a limiting part 31 is provided at the free end of the threaded rod 32, thereby limiting the support part 2. In this way, a space for placing the ejector part 4 is formed between the fixing part 1 and the support plate 21, and the ejector part 4 is placed in the space. Thus, the installation of this device is completed.

[0055] Then, the force output end 41 of the ejector 4 is brought into contact with the connecting pin 30. At this time, the ejector 4 is activated. During this process, the force output end 41 will continue to move along the ejector 4, thereby driving the connecting pin 30 to move until the connecting pin 30 disengages from the user object 100. Thus, the work of removing the connecting pin 30 from its user object 100 is completed.

[0056] However, when the force output end 41 reaches its limit and still cannot disengage the connecting pin 30 from the user object 100, the force output end 41 moves toward the ejector part 4, thereby retracting the ejector part 4. At the same time, a force is applied to the support plate 21, causing the support plate 21 to move along the adjustment part 3 until the force output end 41 abuts against the connecting pin 30 again.

[0057] At this time, the support plate 21 is limited by the limiting part 31. Finally, the ejector part 4 is activated again. During this process, the force output end 41 will continue to move along the ejector part 4, thereby driving the connecting pin 30 to move until the connecting pin 30 is disengaged from the user object 100. In this way, the connecting pin 30 is removed from its user object 100.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
