DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1:

[0030] See also Figure 1-6 ,This embodiment proposes a wedge-locking separation device;

[0031] In this embodiment, a wedge-block locking separation device is provided, which includes a rectangular installation box 1, one end of which is provided with a rectangular mounting seat 2, a slidable longitudinal wedge block 3 is provided inside the rectangular installation box 1, one end of the longitudinal wedge block 3 is fixedly connected to the rectangular mounting seat 2, and a locking and separation mechanism for locking and separating the longitudinal wedge block 3 is provided inside the rectangular installation box 1;

[0032] A detachable limiting mechanism is provided on the top of the rectangular installation box 1 to limit the longitudinal wedge block 3 from being locked inside the rectangular installation box 1;

[0033] The locking and separation mechanism includes two electromagnet cylinders 4, both ends of the rectangular installation box 1 are bolted with electromagnet cylinders 4, a movable transverse push rod 5 is provided inside the electromagnet cylinder 4, both ends of the interior of the rectangular installation box 1 are rotatably connected to vertical rotating columns 8 through bearings, a rectangular rotating plate 7 is fixed to the outside of the vertical rotating column 8 and the rectangular rotating plate 7 is located inside the rectangular installation box 1, a first rigid spring 6 is provided between the rectangular rotating plate 7 and the transverse push rod 5, one side of the rectangular rotating plate 7 is rotatably connected to a vertical rotating column 10 through a bearing, a rectangular limiting plate 11 is fixed to the outside of the vertical rotating column 10, and a torsion spring 12 is provided at the top and bottom of the vertical rotating column 10 and inside the rectangular rotating plate 7;

[0034] A rectangular groove is formed inside the rectangular rotating plate 7. The transverse push rod 5 passes through the rectangular groove and fits with the rectangular rotating plate 7 through the rectangular groove gap. Due to the arrangement of the rectangular groove, when the transverse push rod 5 moves, the elasticity of the first rigid spring 6 enables the rectangular rotating plate 7 to rotate around the vertical rotating column 8 as the center of the circle, thereby enabling the vertical rotating column 10 to move toward the longitudinal wedge block 3.

[0035] A first inclined surface 31 is formed on the inner side of the longitudinal wedge block 3, and a second inclined surface 111 adapted to the first inclined surface 31 is formed on the side of the rectangular limiting plate 11 close to the first inclined surface 31. By disposing the first inclined surface 31 and the second inclined surface 111, when the first inclined surface 31 and the second inclined surface 111 are in contact with each other, the movement of the longitudinal wedge block 3 inside the rectangular installation box 1 can be locked, thereby allowing the longitudinal wedge block 3 to be locked inside the rectangular installation box 1.

[0036] Rectangular guide blocks 9 are fixed to the top and bottom ends of the rectangular installation box 1, and rectangular guide grooves are provided at the top and bottom ends of the longitudinal wedge block 3. The rectangular guide blocks 9 are slidably connected to the longitudinal wedge block 3 through the rectangular guide grooves and the rectangular guide blocks 9, thereby guiding the movement of the longitudinal wedge block 3 inside the rectangular installation box 1, so that the movement of the longitudinal wedge block 3 inside the rectangular installation box 1 is restricted by the rectangular guide blocks 9;

[0037] Here, after the longitudinal wedge block 3 is inserted into the interior of the rectangular installation box 1, the longitudinal wedge block 3 is able to slide on the outside of the rectangular guide block 9. After the electromagnetic cylinder 4 is energized, the operation of the electromagnetic cylinder 4 enables the transverse push rod 5 to move. The movement of the transverse push rod 5 is set by the first rigid spring 6, so that the rectangular rotating plate 7 can rotate with the vertical rotating column 8 as the center of the circle. The rotation of the vertical rotating column 8 enables the rectangular limiting plate 11 to rotate toward the longitudinal wedge block 3. When the first inclined surface 31 is in contact with the second inclined surface 111, the torsion spring 12 is deformed by force, and the first inclined surface 31 is tightly in contact with the second inclined surface 111, thereby limiting the movement of the longitudinal wedge block 3 inside the rectangular installation box 1, thereby enabling the longitudinal wedge block 3 to be locked inside the rectangular installation box 1;

[0038] When the longitudinal wedge block 3 needs to be separated from the interior of the rectangular installation box 1, the operation of the electromagnet cylinder 4 enables the lateral push rod 5 to move away from the rectangular rotating plate 7, and then through the setting of the first rigid spring 6, the rectangular rotating plate 7 can rotate with the vertical rotating column 8 as the center of the circle. Through the setting of the torsion spring 12, the rectangular limit plate 11 can release the restriction on the longitudinal wedge block 3, so that the longitudinal wedge block 3 can be disassembled and the longitudinal wedge block 3 can be quickly unlocked.

[0039] By making full use of the wedge principle, only a very small compression force of the torsion spring 12 is required to achieve reliable locking in the closed state, which reduces the load requirement of the torsion spring 12, extends the service life of the torsion spring 12, simplifies the structure of the device, reduces manufacturing costs and maintenance difficulty, and the unlocking process is fast and stable, with a response speed of up to milliseconds, ensuring that the separation action can only move vertically and will not deviate from the separation trajectory.

[0040] Example 2:

[0041] See also Figure 7 Based on the same concept as the first embodiment above, this embodiment further proposes a limiting mechanism;

[0042] In this embodiment, the limiting mechanism includes a U-shaped mounting plate 13, which is bolted to the top of the rectangular mounting box 1, so that the device can remove the U-shaped mounting plate 13 by bolts, and a first arc-shaped fixing plate 14 is fixed at the middle position of the top of the U-shaped mounting plate 13. The interior of the first arc-shaped fixing plate 14 is slidably connected to a longitudinal light rod 15, and a rectangular pull plate 16 is fixed to one end of the longitudinal light rod 15. A longitudinal sliding plate 18 is fixed to the outside of the longitudinal light rod 15. The first arc-shaped fixing plate 14 is fixed to the middle position of the top of the U-shaped mounting plate 13. A second rigid spring 17 is provided between the fixed plate 14 and the longitudinal sliding plate 18 and on the outside of the longitudinal polished rod 15. Both ends of the longitudinal sliding plate 18 are rotatably connected to an oblique rotating plate 19 through a pin. Both ends of the top of the U-shaped mounting plate 13 are fixed with a second arc-shaped fixed plate 22. The second arc-shaped fixed plate 22 is close to a transverse polished rod 21 at one end of the vertical rotating column 8. A circular limiting tube 20 is slidably connected to the outside of the transverse polished rod 21. The oblique rotating plate 19 and the circular limiting tube 20 are rotatably connected through a pin.

[0043] A circular limiting hole is provided inside the vertical rotating column 8. The circular limiting tube 20 is located inside the circular limiting hole and is fitted with the vertical rotating column 8 through the circular limiting hole. The circular limiting hole allows the circular limiting tube 20 to enter the interior of the vertical rotating column 8. When the circular limiting tube 20 enters the interior of the vertical rotating column 8, it can limit the movement of the vertical rotating column 8 inside the rectangular installation box 1.

[0044] A circular through hole is formed inside the first curved fixing plate 14. The longitudinal polished rod 15 is located inside the circular through hole and is slidably connected to the first curved fixing plate 14 through the circular through hole. The circular through hole enables the longitudinal polished rod 15 to slide longitudinally inside the first curved fixing plate 14.

[0045] Here, the U-shaped mounting plate 13 is installed to the top of the rectangular mounting box 1 by bolts, and the rectangular pull plate 16 is pulled in the direction away from the first arc-shaped fixed plate 14. The pulling of the rectangular pull plate 16 causes the longitudinal sliding plate 18 to move. The movement of the longitudinal sliding plate 18 causes the second rigid spring 17 to be stretched under force. The movement of the longitudinal sliding plate 18 enables the circular limiting tube 20 to slide on the outside of the transverse light rod 21 through the oblique rotating plate 19, thereby enabling the circular limiting tube 20 to move toward the direction of the second arc-shaped fixed plate 22. When the electromagnet cylinder 4 cannot operate, the vertical rotating column 8 is rotated. When the second inclined surface 111 is tightly fitted with the first inclined surface 31, the pull on the rectangular pull plate 16 can be released. The elasticity of the second rigid spring 17 allows the circular limiting tube 20 to enter the interior of the vertical rotating column 8, thereby limiting the rotation of the vertical rotating column 8 inside the rectangular mounting box 1, thereby enabling the longitudinal wedge block 3 to be locked inside the rectangular mounting box 1.

[0046] Through the design of the detachable limiting mechanism, when the electromagnetic cylinder 4 is not in action, the longitudinal wedge block 3 can be reliably locked. The overall structural design is simple, the number of parts is small, and it is easy to process and assemble.

[0047] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0048] Working principle: When using the separation device of the present technical solution, after the longitudinal wedge block 3 is inserted into the interior of the rectangular installation box 1, the longitudinal wedge block 3 is able to slide on the outside of the rectangular guide block 9. After the electromagnet cylinder 4 is energized, the operation of the electromagnet cylinder 4 enables the transverse push rod 5 to move. The movement of the transverse push rod 5 is caused by the setting of the first rigid spring 6, so that the rectangular rotating plate 7 can rotate with the vertical rotating column 8 as the center of the circle. The rotation of the vertical rotating column 8 enables the rectangular limiting plate 11 to rotate toward the longitudinal wedge block 3. When the first inclined surface 31 fits with the second inclined surface 111, the torsion spring 12 is deformed by force, and the first inclined surface 31 fits tightly with the second inclined surface 111, thereby limiting the movement of the longitudinal wedge block 3 inside the rectangular installation box 1, thereby enabling the longitudinal wedge block 3 to be locked inside the rectangular installation box 1.

[0049] When the longitudinal wedge block 3 needs to be separated from the interior of the rectangular installation box 1, the operation of the electromagnet cylinder 4 enables the lateral push rod 5 to move away from the rectangular rotating plate 7. Then, through the setting of the first rigid spring 6, the rectangular rotating plate 7 can rotate with the vertical rotating column 8 as the center of the circle. Through the setting of the torsion spring 12, the rectangular limiting plate 11 can release the restriction on the longitudinal wedge block 3, so that the longitudinal wedge block 3 can be removed and the longitudinal wedge block 3 can be quickly unlocked.

[0050] The U-shaped mounting plate 13 is mounted to the top of the rectangular mounting box 1 by bolts, and the rectangular pull plate 16 is pulled in the direction away from the first arc-shaped fixed plate 14. The pulling of the rectangular pull plate 16 causes the longitudinal sliding plate 18 to move. The movement of the longitudinal sliding plate 18 causes the second rigid spring 17 to be stretched under force. The movement of the longitudinal sliding plate 18 enables the circular limiting tube 20 to slide on the outside of the transverse light rod 21 through the oblique rotating plate 19, thereby enabling the circular limiting tube 20 to move toward the direction of the second arc-shaped fixed plate 22. When the electromagnet cylinder 4 cannot operate, the vertical rotating column 8 is rotated. When the second inclined surface 111 is tightly fitted with the first inclined surface 31, the pull on the rectangular pull plate 16 can be released. The elasticity of the second rigid spring 17 allows the circular limiting tube 20 to enter the interior of the vertical rotating column 8, thereby limiting the rotation of the vertical rotating column 8 inside the rectangular mounting box 1, thereby enabling the longitudinal wedge block 3 to be locked inside the rectangular mounting box 1.

[0051] All technical features in this embodiment can be freely combined according to actual needs.

[0052] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
