[0039] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0040] The pin plugging and extraction auxiliary tooling and the pin plugging and extraction device according to the present application are described below with reference to the accompanying drawings.

[0041] like Figures 1 to 5 As shown, the pin plugging and pulling auxiliary tooling 2 of the present application includes a tooling base plate 9 and a suspension support structure. The tooling base plate 9 is used to support the top surface of the pin shaft connection position of the tower crane attachment structure 3. Specifically, the tooling base plate 9 is provided with a base plate fixing structure, which cooperates with the tower crane attachment structure 3 to lock the tooling base plate 9 on the top surface of the pin shaft connection position; a base plate through hole is also formed in the middle of the tooling base plate 9. When the tooling base plate 9 is locked in the pin shaft connection position, the base plate through hole can be used for the connection pin shaft 4 to pass through to insert or pull out of the pin shaft connection position; the suspension support structure extends upward from the tooling base plate 9 and is used to support the suspended pin plugging and pulling device 1. The pin plugging and pulling device 1 is used in conjunction with the connection pin shaft 4. When the tooling base plate 9 is locked in the pin shaft connection position, the suspended pin plugging and pulling device 1 can be vertically aligned with the base plate through hole to facilitate driving the connection pin shaft 4 to insert or pull out of the pin shaft connection position.

[0042] It can be seen that the pin plugging and extraction auxiliary tooling 2 of the present application can lock itself on the tower crane attachment structure 3 through the base plate fixing structure, so that the base plate through hole is aligned with the pin shaft connection position, and use the suspended support structure to support the suspended pin plugging and extraction device 1, so that the pin plugging and extraction device 1 is vertically aligned with the base plate through hole, thereby the pin plugging and extraction device 1 can be used to drive the connecting pin shaft 4 to be inserted into or pulled out of the pin shaft connection position through the base plate through hole, thereby realizing the automated operation of plugging and pulling out the connecting pin shaft 4, saving time and effort and effectively ensuring the safety of construction personnel, improving the operating efficiency of disassembly and assembly of the tower crane attachment structure, and at the same time reducing the probability of damage to the connecting pin shaft during the plugging and pulling process, thereby effectively extending its service life.

[0043] In an optional or preferred embodiment, referring to Figures 1 to 5The bottom plate fixing structure includes an ear plate avoidance hole, a locking ear plate group and a locking pin shaft 12. Among them, the ear plate avoidance hole is formed on the tooling bottom plate 9 and is used for the attachment structure ear plate (not shown in the figure) fixed on the top surface of the pin shaft connection position to pass upward. In other words, the attachment structure ear plate and the tooling bottom plate 9 are plugged in through the ear plate avoidance hole; the locking ear plate group includes two locking ear plates 11 arranged on the top surface of the tooling bottom plate 9, and the two locking ear plates 11 are respectively located on the lateral sides of the ear plate avoidance hole. Therefore, when the attachment structure ear plate passes through the ear plate avoidance hole, it can be located between the two locking ear plates 11. At this time, the locking pin shaft 12 can be used to connect and fix the two locking ear plates 11 with the attachment structure ear plate, thereby realizing the fixing of the plug-in pin auxiliary tooling 2 to the tower crane attachment structure 3.

[0044] In an optional or preferred embodiment, referring to Figure 5 , there are multiple ear plate avoidance holes and locking ear plate groups, and multiple locking ear plate groups are arranged in sequence around the bottom plate through hole, and multiple ear plate avoidance holes are arranged in a one-to-one correspondence with multiple locking ear plate groups. Therefore, when fixing the plug-in pin auxiliary tooling 2, according to the setting of the attachment structure ear plate of the tower crane attachment structure 3, one of the ear plate avoidance holes and its corresponding locking ear plate group can be selected to match and connect with one attachment structure ear plate, or multiple ear plate avoidance holes and their corresponding multiple locking ear plate groups can be selected to match and connect with multiple attachment structure ear plates one by one, and this exemplary embodiment does not limit this. It can be understood that when multiple ear plate avoidance holes and their corresponding multiple locking ear plate groups are matched and connected with multiple attachment structure ear plates one by one, the connection strength between the plug-in pin auxiliary tooling 2 and the tower crane attachment structure 3 can be improved, thereby improving the stability of the tooling.

[0045] In an optional or preferred embodiment, the suspension support structure is provided with two suspension holes which are spaced parallel to each other in the transverse direction and are respectively used to support the suspension shaft (not shown in the drawings) in the pin inserter 1 at both lateral ends, and the peripheral wall of the suspension hole is provided with a notch for inserting or removing the suspension shaft.

[0046] For example, refer to Figure 3 and Figure 4The suspension support structure includes two support uprights 6 and two suspension support plates 10. The two support uprights 6 are parallel and spaced apart and vertically connected to the top surface of the tooling bottom plate 9. The two suspension support plates 10 are respectively connected to the two support uprights 6. Two suspension holes are respectively formed in the two suspension support plates 10, wherein the peripheral wall of the suspension support plate 10 is concave to form an opening that passes through the suspension hole, thereby forming a notch portion of the suspension hole. Thus, the suspension axis of the pin inserter 1 can be placed in the two suspension support plates 10 through the notch portion, and then the pin inserter 1 is supported by the two suspension support plates 10, so that the pin inserter 1 is suspended between the two support uprights 6. It can be seen that by providing the notch portion in the two suspension support plates 10, the pin inserter 1 can be quickly disassembled and assembled, thereby improving the convenience of tooling use.

[0047] In an optional or preferred embodiment, referring to Figures 1 to 4 The suspended support structure includes a first supporting transverse plate and a second supporting transverse plate, the two lateral ends of the first supporting transverse plate are respectively connected to the first long sides of the two supporting vertical plates 6, and the two lateral ends of the second supporting transverse plate are respectively connected to the second long sides of the two supporting vertical plates 6, so that the first supporting transverse plate, the second supporting transverse plate and the two supporting vertical plates 6 together form a stable frame structure. Therefore, when the pin inserter 1 is suspended between the two supporting vertical plates 6, the first supporting transverse plate and the second supporting transverse plate can effectively limit the pin inserter 1 to improve safety.

[0048] Furthermore, considering the disassembly and assembly requirements of the pin inserter and extractor 1, at least one of the first supporting transverse plate and the second supporting transverse plate is formed as a detachable transverse plate 7 that can be removed from the supporting vertical plate 6. For example, the detachable transverse plate 7 and the supporting vertical plate 6 can be detachably connected by bolts. At the same time, the notch portion of the hanging supporting plate 10 is arranged to open laterally toward the side where the detachable transverse plate 7 is provided. Therefore, when the detachable transverse plate 7 located on one side of the two supporting vertical plates 6 is removed, the pin inserter and extractor 1 can enter or move out of the suspended swing position between the two supporting vertical plates 6 from this side. The pin inserter and extractor 1 that enters the suspended swing position can then be suspended on the two hanging supporting plates 10 through the notch portion, and there is no need to adjust the placement direction of the hanging axis of the pin inserter and extractor 1, which is convenient and quick.

[0049] In some other embodiments, the hanging support structure can be composed of a connecting horizontal plate and two connecting vertical plates, the two connecting vertical plates are parallel and spaced and vertically connected to the top surface of the tooling bottom plate 9, the lateral ends of the connecting horizontal plate are respectively connected to the top ends of the two connecting vertical plates, so that the hanging support structure is formed into a gate arch structure, and the connecting horizontal plate is provided with a fixed installation hole that is vertically aligned with the bottom plate through hole and is used for the pin plugging and pulling device 1 to be vertically inserted and fixed. Therefore, when the pin plugging and pulling device 1 is vertically inserted and fixed to the fixed installation hole of the connecting horizontal plate, it can be suspended between the two connecting vertical plates. At this time, the telescopic end of the pin plugging and pulling device 1 is aligned with the bottom plate through hole, which is convenient for driving the connecting pin shaft 4 to be inserted and pulled out of the pin shaft connection position of the tower crane attachment structure 3.

[0050] In an optional or preferred embodiment, referring to Figure 1 The plug-in pin auxiliary tooling 2 also includes a reinforcing rib plate 8 connecting the supporting vertical plate 6 and the tooling bottom plate 9. Specifically, the reinforcing rib plate 8 is welded between the supporting vertical plate 6 and the tooling bottom plate 9, thereby enhancing the stability of the entire tooling.

[0051] In an optional or preferred embodiment, referring to Figure 1 The pin-plugging auxiliary tooling 2 includes a lifting ear 5 connected to the top of the suspended support structure, and the lifting ear 5 can be passed through an external lifting mechanism to facilitate the use of the lifting mechanism to lift the pin-plugging auxiliary tooling 2 to the pin shaft connection position of the tower crane attachment structure 3.

[0052] The second exemplary embodiment of the present application provides a pin insertion and extraction device, which includes the above-mentioned pin insertion and extraction auxiliary tooling 2 and the pin insertion and extraction device 1, wherein the pin insertion and extraction device 1 is suspended, and supported by the suspension support structure of the pin insertion and extraction auxiliary tooling 2, the pin insertion and extraction device 1 is vertically aligned with the bottom plate through hole. Obviously, the pin insertion and extraction device of this exemplary embodiment has all the technical effects brought by the above-mentioned pin insertion and extraction auxiliary tooling 2, so it will not be repeated here.
