DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with specific embodiments, but the implementation methods of the present invention are not limited thereto.

[0033] Embodiment 1

[0034] See also Figure 1 , Figure 1 It is a structural schematic diagram of a portable double-pin crawler end coupling disassembly device provided in an embodiment of the utility model.

[0035] The present embodiment provides a portable double-pin crawler end coupling disassembly device, comprising: a shell 1, a connection structure 2, an impact structure 3, a power transmission structure 4, an pyrotechnic power source 5 and an excitation structure 6. The connection structure 2 is arranged at one end of the shell 1 for connecting the end coupling. The impact structure 3 is arranged inside the shell 1, and can move along the axial direction of the shell 1 to contact or move away from the pin. The power transmission structure 4 is arranged inside the shell 1, and is located on the side of the impact structure 3 away from the connection structure 2, and the power transmission structure 4 can move along the axial direction of the shell 1 to contact or move away from the impact structure 3. The pyrotechnic power source 5 is arranged inside the shell 1, and is located on the side of the power transmission structure 4 away from the impact structure 3, and the pyrotechnic power source 5 can move along the axial direction of the shell 1 to contact the power transmission structure 4. The excitation structure 6 is arranged inside the shell 1, and is located on the side of the pyrotechnic power source 5 away from the power transmission structure 4, and the excitation structure 6 can move along the axial direction of the shell 1 to contact the pyrotechnic power source 5.

[0036] Specifically, the shape of the connection structure 2 is adapted to the end coupler. When the end coupler and the pin are disassembled, the end coupler is fixed inside the connection structure 2, and the wrench on the shell 1 is pressed to excite the structure 6 to move axially along the shell 1 until it hits the pyrotechnic power source 5. The pyrotechnic power source 5 is excited after being hit by the excitation structure 6, and moves axially along the shell 1 to contact the power transmission structure 4, applying an axial impact force to the power transmission structure 4. After the power transmission structure 4 is subjected to the axial impact force, it moves axially along the shell 1 and transmits the axial impact force to the impact structure 3. Under the action of the axial impact force, the impact structure 3 moves axially along the shell 1 and hits the pin in the pin hole of the end coupler, causing a relative displacement between the end coupler and the pin to knock the pin out of the pin hole of the end coupler.

[0037] Specifically, the impact structure 3, the power transmission structure 4, the pyrotechnic power source 5 and the excitation structure 6 are all coaxially arranged.

[0038] In this embodiment, the end coupler disassembly device further includes a fastener, and a connecting hole 21 is formed on the side wall of the connecting structure 2. The fastener is connected to the end coupler through the connecting hole 21.

[0039] Specifically, a threaded hole is provided between the two pin holes of the end coupler, and the connection hole 21 corresponds to the threaded hole of the end coupler. The end coupler is placed in the connection structure 2 through the open end of the connection structure 2, the connection hole 21 is aligned with the threaded hole of the end coupler, and the fastener passes through the connection hole 21 and the threaded hole of the end coupler to connect, so as to fix the end coupler disassembly device and the end coupler. Exemplarily, the fastener includes a screw.

[0040] In this embodiment, the impact structure 3 includes: a connecting portion 31, a first shaft portion 32 and a second shaft portion 33. The connecting portion 31 is arranged inside the housing 1. The first shaft portion 32 and the second shaft portion 33 are arranged relatively on the surface of the connecting portion 31 close to the connecting structure 2, and the distance between the first shaft portion 32 and the second shaft portion 33 is equal to the distance between the two pin holes of the end coupler. The first shaft portion 32 and the second shaft portion 33 are both parallel to the axial direction of the housing 1.

[0041] Specifically, the first shaft portion 32 and the second shaft portion 33 correspond to the two pin holes of the end coupler, and the power transmission structure 4 hits the connecting portion 31. Under the axial force, the connecting portion 31 drives the first shaft portion 32 and the second shaft portion 33 to move axially along the shell 1. The first shaft portion 32 and the second shaft portion 33 hit the pin shafts in the two pin holes of the end coupler, so that a relative displacement occurs between the end coupler and the pin shafts, so as to knock the pin shafts out of the pin holes of the end coupler.

[0042] In this embodiment, a first impact hole and a second impact hole are formed at one end of the housing 1. The first shaft portion 32 is inserted into the first impact hole and can move axially along the first impact hole. The second shaft portion 33 is inserted into the second impact hole and can move axially along the second impact hole.

[0043] Specifically, the first impact hole and the second impact hole are formed on the end surface of the housing 1 connected to the connection structure 2. The diameter of the first impact hole is slightly larger than the first shaft portion 32, and the diameter of the second impact hole is slightly larger than the second shaft portion 33, so that the axial movement of the first shaft portion 32 and the second shaft portion 33 is not restricted, and no circumferential displacement occurs, thereby ensuring the stability of the end coupling disassembly equipment during operation.

[0044] In this embodiment, the pyrotechnic power source 5 includes a blank cartridge. The excitation structure 6 includes a firing pin spring structure. After pressing the wrench on the housing 1, the excitation structure 6 converts elastic potential energy into kinetic energy, and under the action of the kinetic energy, moves axially and hits the blank cartridge. The blank cartridge is excited after being hit by the excitation structure 6, and a sufficiently large axial impact force is generated. The axial impact force acts on the pin shaft through the power transmission structure 4 and the impact structure 3 in turn, so as to separate the pin shaft from the end coupling.

[0045] In this embodiment, the housing 1 includes: a main housing 11 and a power source housing 12. One end of the main housing 11 is fixedly connected to the connection structure 2, and a first moving track is arranged inside the main housing 11. The power source housing 12 is detachably connected to the other end of the main housing 11, and a second moving track, a third moving track and a fourth moving track are arranged in sequence inside the power source housing 12 in a direction away from the main housing 11. The first moving track, the second moving track, the third moving track and the fourth moving track are axially connected. A limiting structure is arranged at one end of the power transmission structure 4 close to the pyrotechnic power source 5.

[0046] Specifically, the impact structure 3 is arranged in the first motion track and can move axially in the first motion track. The power transmission structure 4 is arranged in the second motion track and can move axially in the second motion track. The pyrotechnic power source 5 is arranged in the third motion track and can move axially in the third motion track. The excitation structure 6 is arranged in the fourth motion track and can move axially in the fourth motion track. The other end of the main housing 11 is provided with a through hole of the same size as the second motion track, the first motion track and the second motion track are connected through the through hole, and the diameter of the limiting structure of the power transmission structure 4 is greater than the diameter of the second motion track. When disassembling the end connector and the pin shaft, align the positions of the first shaft portion 32, the second shaft portion 33 and the two pin shafts, as well as the positions of the connecting hole 21 and the threaded hole of the end connector, and fix the connecting structure 2 and the end connector by a screw. Then, one end of the power transmission structure 4 is inserted into the first motion track through the through hole on the main housing 11, and one end of the power source housing 12 is fixedly connected to the other end of the main housing 11 by a threaded structure. By pressing the wrench on the housing 1, the exciting structure 6 moves axially along the fourth motion track, partially enters the third motion track, hits and excites the pyrotechnic power source 5 in the third motion track. After being excited, the pyrotechnic power source 5 moves axially along the third motion track, enters the second motion track, and applies an axial impact force to the power transmission structure 4 in the second motion track. After the power transmission structure 4 is subjected to the axial impact force, it moves axially in the second motion track, partially enters the first motion track, hits the impact structure 3 in the first motion track, and transmits the axial impact force to the impact structure 3. Under the action of the axial impact force, the impact structure 3 moves axially in the first motion track, hits the pin shaft in the pin hole of the end coupler, and causes a relative displacement between the end coupler and the pin shaft to knock the pin shaft out of the pin hole of the end coupler. The limiting structure of the power transmission structure 4 can limit the maximum axial displacement of the power transmission structure 4 to ensure the normal operation of the end coupler disassembly equipment. During the transfer process of the end coupling disassembly device, the threaded connection between the main housing 11 and the power source housing 12 is released, so that the device can be divided into two separate parts, which effectively reduces the storage space of the device and improves the portability of the device.

[0047] This embodiment provides a portable double-pin crawler end coupler disassembly device, which excites the pyrotechnic power source 5 through the excitation structure 6, so that the pyrotechnic power source 5 generates an axial impact force, and the axial impact force acts on the pin shaft through the power transmission structure 4 and the impact structure 3 in turn, so that the end coupler and the pin shaft are relatively displaced, so as to knock the pin shaft out of the pin hole of the end coupler, and complete the disassembly operation of the end coupler and the pin shaft. The device is easy to carry and suitable for field operation environments. No cooperation is required during use, and a single person can complete the disassembly operation.
