At the same time, in the description of the present utility model, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] like Figures 1 to 3As shown, a locking structure for disassembling and assembling a coupler comprises: a coupler disassembling tool is provided at one end of the connecting structure 1, a disassembling pin hole is provided at the top of the coupler disassembling tool, a balancing bar 2 is transversely provided on the platform of the connecting structure 1, a locking block 4 is suspended at one end of the balancing bar 2, and the bottom end of the locking block 4 is arranged in the disassembling pin hole; a rotating device 3, the rotating device 3 is connected to the other end of the connecting structure 1, a telescopic component 5 is provided at the top of the rotating device 3, and the moving end of the telescopic component 5 extends toward the balancing bar 2 to form a connecting pin hole Contact 51, when the moving end of the telescopic component 5 moves downward, the contact head 51 contacts the end of the balance bar 2 away from the locking block 4, the moving end of the telescopic component 5 continues to move downward and applies pressure to the balance bar 2, the end of the balance bar 2 away from the locking block 4 tilts upward, the balance bar 2 drives the locking block 4 to lift up, and the coupler disassembly and assembly tool is unlocked; when the moving end of the telescopic component 5 rises, the locking block 4 falls into the disassembly pin hole under the influence of gravity, and the locking block 4 is engaged with the coupler disassembly and assembly tool to form a locked state. The working process of this structure is as follows: the moving end of the telescopic assembly 5 is adjusted so that the telescopic assembly 5 is in a raised state, the coupler disassembly and assembly tool is aligned with the coupler on the vehicle body to be repaired for connection, and it is ensured that the locking block 4 falls into the disassembly and assembly pin hole. After the coupler disassembly and assembly tool is in a locked state, the slewing device 3 drives the connecting structure 1 and the coupler disassembly and assembly tool to rotate so that the hook tail pin on the coupler automatically falls off; when the slewing device 3 drives the connecting structure 1 and the coupler disassembly and assembly tool to rotate back to the normal position, the coupler on the vehicle body to be repaired is placed in the designated storage position, and the moving end of the telescopic assembly 5 moves downward, and the contact head 51 contacts the balance bar 2, so that the locking block 4 is lifted, and the coupler disassembly and assembly work is unlocked, and the coupler disassembly operation is completed at this time.

[0027] In the present invention, the telescopic assembly 5 includes an angle structure 52 and a push rod 53, the top end of the push rod 53 is connected to the angle structure 52, and the bottom end of the push rod 53 is arranged on the top end of the slewing device 3. When the moving end of the push rod 53 moves downward, the angle structure 52 contacts the end of the balance bar 2 away from the locking block 4. The arrangement of the angle structure 52 and the push rod 53 makes the angle structure 52 contact the balance bar 2, so that the locking block 4 is lifted up, and the locking block 4 cannot fall into the disassembly pin hole, and the coupler disassembly tool is in an unlocked state, so that the coupler on the vehicle body to be repaired can be disassembled from the vehicle body to be repaired.

[0028] To clarify the specific setting of the angle structure 52, the angle structure 52 includes a first straight rod and a second straight rod, the first straight rod is arranged on the top end of the push rod 53, the first straight rod extends laterally toward the balance pole 2, one end of the first straight rod extending toward the balance pole 2 is fixedly connected to one end of the second straight rod, and the other end of the second straight rod extends vertically toward the balance pole 2 to form a contact head 51.

[0029] like Figure 2 As shown, the balancing rod 2 includes a first suspension rod 21 and a second suspension rod 22, one end of the first suspension rod 21 is connected to one end of the second suspension rod 22, and a suspension rod mounting hole is provided at the other end of the first suspension rod 21. Preferably, the second suspension rod 22 is configured as a slope type. On the one hand, the second suspension rod 22 reduces the contact distance with the contact head 51, and on the other hand, the configuration of the second suspension rod 22 reduces the magnitude of the applied force, which is beneficial for the first suspension rod 21 to lift up and drive the locking block 4.

[0030] In the present invention, the locking block 4 is an "L"-shaped bent pin structure, a locking mounting hole is provided at the top of the locking block 4, a connecting member 6 passes through the suspension rod mounting hole and the locking mounting hole, and the connecting member 6 connects the locking block 4 and the first suspension rod 21. The bottom end of the locking block 4 is chamfered, and the bottom end of the locking block 4 is convenient for falling to the position guidance during the process of disassembling and assembling the pin hole.

[0031] In this structure, the connection structure 1 includes a transverse support rod 11 and a disassembly base 12. One end of the transverse support rod 11 is rotatably connected to the slewing device 3, and the other end of the transverse support rod 11 is fixedly connected to the disassembly base 12. The other end of the disassembly base 12 is connected to the coupler disassembly tool. Preferably, the transverse support rod 11 is a circular structure, and the disassembly base 12 is a rectangular structure.

[0032] Furthermore, the connection structure 1 includes a vertical support rod 13, the bottom end of the vertical support rod 13 is arranged on the transverse support rod 11, the vertical support rod 13 is a hollow structure in the length direction, the second suspension rod 22 is arranged in the hollow structure, the second suspension rod 22 is hinged to the vertical support rod 13 through a balance pin, and the second suspension rod 22 rotates around the balance pin. In this structure, on the one hand, the vertical support rod 13 supports the balance rod 2, and on the other hand, the vertical support rod 13 provides a rotation position for the balance rod 2 to prevent the balance rod 2 from being displaced.

[0033] To clarify the specific implementation of the slewing device 3, a driving end is provided on the side wall of the slewing device 3, and the driving end is connected to one end of the transverse support rod 11. The slewing device 3 drives the transverse support rod 11, the disassembly base 12 and the coupler disassembly tool to rotate through the driving end. The slewing device 3 is driven by a motor. When the coupler disassembly tool is connected to the coupler on the vehicle body to be repaired, the driving end of the slewing device 3 drives the coupler disassembly tool to rotate, and the coupler tail pin on the coupler to be repaired automatically falls off after the rotation.

[0034] like Figure 1 As shown, the lifting device 7 and the lifting motor 8 are also included. The lifting device 7 and the lifting motor 8 are electrically connected. The lifting end of the lifting device 7 is provided with the rotating device 3. The lifting motor 8 drives the rotating device 3 to move up and down along the lifting device 7. The lifting motor 8 drives the rotating device 3, the connecting structure 1 and the coupler disassembly and assembly tool to move along the lifting device 7, so that the coupler disassembly and assembly tool is aligned with the coupler on the vehicle body to be repaired, so as to perform the disassembly operation.

[0035] like Figure 4 and Figure 5 As shown, a hook tongue is provided in the coupler disassembly and assembly tool, and a first channel and a second channel are formed between the hook tongue and the disassembly pin hole, and the first channel and the second channel are vertically arranged. When the bottom end of the locking block 4 falls into the first channel, the hook tongue contacts the L-shaped corner of the locking block 4 to form a locked state; when the locking block 4 is vertically upwardly forced to push the hook tongue open, the bottom end of the locking block 4 slides from the first channel to the second channel, and the coupler disassembly and assembly tool is unlocked. When the bottom end of the locking block 4 falls to the first channel, the locking block 4 will hold up the hook tongue, preventing the hook tongue from falling. During the rotation of the locking block 4 through the rotating device 3, the inclined surface of the hook tongue and the bending structure of the hook tongue will prevent the locking block 4 from falling out due to gravity or normal working force. When the locking block 4 is pushed vertically upward by the hook tongue, the iron pushing structure of the hook tongue will make the hook tongue slide to the second channel. The locking block 4 needs a larger escape force to escape from the first channel. The mobile end of the telescopic component 5 provides a power source, and the telescopic component 5 drives the locking block 4 to move to the second channel, and the coupler disassembly and assembly tooling is unlocked.

For those skilled in the art, the utility model can have various modifications and changes.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
