[0045] The upper assembly rear seat plate 103 is provided with a through hole, and the position close to the lower end between the two upper assembly side seat plates 101 is provided with a push-pull device. The rear end of the push-pull device is fixedly provided with a limiting pin shaft 9, and the limiting pin shaft 9 is located in the hole in the upper assembly rear seat plate 103. The push-pull device can drive the limiting pin shaft 9 to move forward and backward in the hole.

[0053] When the lower segment position of the connector upper assembly 1 is inserted into the inside of the connector lower assembly 2, the two first locking grooves 10101 can be attached to the second locking shaft 204, after attachment, when the push-pull device moves backward, the limiting pin shaft 9 can enter the inside of the hole on the lower assembly rear seat plate 202, limiting and locking the rear end position of the connector upper assembly 1 and the connector lower assembly 2, while the push-pull device moves backward, the thrust sliding block 5 moves backward, while the thrust sliding block 5 moves backward, the limiting baffle assembly 6 is driven to move downward, when the limiting baffle assembly 6 moves downward, the lower segment part of the limiting baffle assembly 6 can enter the position inside the first locking groove 10101 in the longitudinal direction, limiting and locking the second locking shaft 204, limiting and locking the front end position of the connector upper assembly 1 and the connector lower assembly 2, finally, the connector upper assembly 1 and the connector lower assembly 2 are quickly locked and fixed.

[0054] In order to further ensure the stability of the push-pull device structure, the following embodiments are adopted:

[0055] In this embodiment, the push-pull device is an oil cylinder assembly 3, which includes a valve block 301 and a linear oil cylinder 302. The rear end of the linear oil cylinder 302 is fixedly provided with a limit pin shaft fixing plate 7, and the rear end of the limit pin shaft fixing plate 7 is fixedly connected with the front end of a limit pin shaft 9. When the linear oil cylinder 302 moves forward and backward, the limit pin shaft 9 moves forward and backward in the hole of the upper assembly rear seat plate 103, thereby realizing the quick locking of the rear end positions of the connector upper assembly 1 and the connector lower assembly 2.

[0056] According to the specific structure of the thrust block 5, the thrust block 5 is provided with a thrust block fixed segment 501 and a thrust block sliding segment 502. The thrust block fixed segment 501 is located at the rear position of the thrust block 5, and the thrust block sliding segment 502 is located at the front position of the thrust block 5. The thrust block fixed segment 501 is fixedly connected with the front end of the linear oil cylinder 302. The lower end of the thrust block sliding segment 502 is provided with a first sliding inclined surface 503, which is a front-low and rear-high inclined surface. The limit baffle assembly 6 is provided with a baffle seat 601 and a baffle 602.

[0057] The baffle positioning seat 10 and the baffle seat 601 are provided with a spring 13 therebetween, and the baffle positioning seat 10 and the baffle seat 601 are supported by the spring 13.

[0058] During the installation of the breaking hammer, the piston of the linear oil cylinder 302 moves backward, driving the thrust block 5 to slide backward. Under the mutual inclined surface fitting of the first sliding inclined surface 503 and the second sliding inclined surface 603, the limit baffle assembly 6 moves downward, and the baffle 602 moves downward through the lower end surface of the baffle positioning seat 10 and enters the position inside the first locking groove 10101 relative to the longitudinal direction. The second locking shaft 204 in the first locking groove 10101 is locked at the rear end of the first locking groove 10101, thereby realizing the quick locking of the front end positions of the connector upper assembly 1 and the connector lower assembly 2. At this time, the spring 13 is in a compressed state.

[0059] When the piston of the linear oil cylinder 302 moves backward, the limit pin shaft 9 enters the hole of the lower assembly rear seat plate 202, thereby realizing the quick locking of the rear end positions of the connector upper assembly 1 and the connector lower assembly 2. Finally, the overall locking of the connector upper assembly 1 and the connector lower assembly 2 is completed.

[0060] In the process of breaking hammer disassembly, the piston on the linear oil cylinder 302 moves axially forward, driving the thrust sliding block 305 to move forward synchronously. Under the mutual inclined surface fitting structure of the first sliding inclined surface 503 and the second sliding inclined surface 603 and the supporting action of the spring 13, the limiting baffle assembly 6 moves upward, and the baffle 602 is separated from the position relative to the longitudinal interior of the first locking groove 10101, realizing the quick disengagement of the front end position of the connector upper assembly 1 and the connector lower assembly 2.

[0061] At the same time, the piston on the linear oil cylinder 302 moves axially forward, driving the limiting pin shaft 9 to move forward and disengage from the inside of the hole on the lower assembly rear plate 202, realizing the quick disengagement of the rear end position of the connector upper assembly 1 and the connector lower assembly 2. Finally, the overall disassembly of the connector upper assembly 1 and the connector lower assembly 2 is completed, and then a breaking hammer of appropriate specification is selected for reinstallation.

[0062] In order to improve the stability of the linear oil cylinder 302 driving the limiting pin shaft 9 and the thrust sliding block 5 moving forward and backward, the following embodiments are adopted:

[0063] In this embodiment, the upper assembly side seat plate connecting seat 4 is fixed between the two upper assembly side seat plates 101, and the upper assembly side seat plate connecting seat 4 is fixedly connected with the shell of the linear oil cylinder 302, forming stable support for the linear oil cylinder 302. In addition, the two sides of the limiting pin shaft fixing plate 7 are fixedly provided with sliding support plates 14, and the inner sides of the two upper assembly side seat plates 101101 are respectively provided with groove plates 15. The sliding support plates 14 are located inside the groove plates 15 and can slide forward and backward inside the groove plates 15, which can increase the stability of the synchronous movement of the linear oil cylinder 302, the sliding support plates 14 and the limiting pin shaft 9, and avoid shaking and displacement.

[0064] The two sides of the limiting pin shaft fixing plate 7 are fixedly provided with sliding support plates 14, and the inner sides of the two upper assembly side seat plates 101 are respectively provided with groove plates 15. The sliding support plates 14 are located inside the groove plates 15 and can slide forward and backward inside the groove plates 15.

[0065] In order to improve the efficiency of quick locking of the front end position of the connector upper assembly 1 and the connector lower assembly 2, the following embodiments are adopted:

[0066] In this embodiment, the thrust chamfer 604 is arranged at the connection between the rear end and the lower end of the baffle plate 602. In actual assembly, after the first locking groove 10101 and the second locking shaft 204 are fitted, misalignment between them is inevitable. By arranging the thrust chamfer 604 on the baffle plate 602, if the second locking shaft 204 is misaligned when the baffle plate 602 moves downward, the position of the thrust chamfer 604 on the baffle plate 602 can push the front section of the second locking shaft 204 downward, quickly correcting the position of the second locking shaft 204, and finally locking and fixing the second locking shaft 204.

[0067] Oil passage block support plates 17 are fixed at positions close to the bottom ends between the two lower assembly side seat plates 201. The oil passage blocks 16 are located at the upper end positions of the oil passage block support plates 17 and are fixedly connected with the oil passage block support plates 17. The oil passage block support plates 17 can increase the connection stiffness of the connector lower assembly 2 and effectively support the oil passage blocks 16, facilitating the assembly of the hydraulic oil pipes on the oil passage blocks 16.

[0068] To increase the convenience of assembling the hydraulic oil pipes, the number of the oil passage block support plates 17 is two. The two oil passage block support plates 17 are respectively located at the front and rear positions between the two lower assembly side seat plates 201. The front and rear end positions of the oil passage blocks 16 are fixedly connected with the two oil passage block support plates 17.

[0069] To increase the stability of the locking of the connector upper assembly 1 and the connector lower assembly 2, the following embodiment is adopted.

[0070] In this embodiment, the number of the limiting pin shafts 9, the holes in the lower assembly rear seat plate 202, and the holes in the upper assembly rear seat plate 103 is two, and they are arranged along the left-right direction. This can prevent the shaking gap of the connector upper assembly 1 and the connector lower assembly 2 after being locked. If the shaking gap occurs, it will directly cause the connector upper assembly 1 or the connector lower assembly 2 to be damaged to different degrees, reducing the operation accuracy and service life of the connector assembly, further increasing the reliability of the locking of the two, and ensuring the stability of the long-time crushing operation.

[0071] To further increase the stability of the structure application of the connector upper assembly 1, the following embodiment is adopted.

[0072] In this embodiment, a reinforcing support plate 12 is fixed between the two upper assembly side seat plates 101 at positions adjacent to the lower ends of the two first locking grooves 10101. The reinforcing support plate 12 can effectively support the periphery of the two first locking grooves 10101, form a whole force structure between the two upper assembly side seat plates 101, and avoid the stress deformation of the single structure of the upper assembly side seat plate 101.

[0073] In order to increase the convenience of hydraulic oil pipe installation, the following embodiment is adopted:

[0074] In this embodiment, two auxiliary operation holes 20101 are arranged on both sides of the bottom end of the oil passage block 16 on the two lower assembly side seat plates 201, and the assembly personnel can pass through the auxiliary operation holes 20101 to perform the installation work of the hydraulic oil pipe, which is simple and fast, saves working time, and is convenient for maintenance. At the same time, through the auxiliary operation hole 20101, it can monitor in real time whether there is oil leakage at the oil pipe interface.
