Detailed Description

The following describes embodiments of the present invention in detail with reference to the accompanying drawings.

As shown in fig. 1 to fig. 3, which are schematic partial structural diagrams of a deep-hole circuit breaker, fig. 1 to fig. 4 show a cabinet surface 1, a handcart driving hexagonal rod 2, a protection sleeve 3, a cabinet body spring 4 and a cabinet surface handcart operation hole 1.1, specifically, a handcart driving hexagonal rod 2 is arranged inside the cabinet body, and the handcart driving hexagonal rod 2 is rotated to drive the circuit breaker in the cabinet body to move, so that state switching of the cabinet body is realized. Protective sleeve 3 covers on the hexagonal pole 2 of handcart drive, and protective sleeve 3 rear end is equipped with the cabinet body spring 4 of great load, need overcome cabinet body spring 4's spring force, impresses protective sleeve 3, makes the hexagonal pole portion of hexagonal pole 2 of handcart drive expose, sheathes handcart operation tool on the hexagonal pole and realizes the operation of circuit breaker. As shown in fig. 3, a cabinet surface handcart operation hole 1.1 is formed in a cabinet surface 1 of the cabinet body, and the handcart operation hole 1.1 is characterized in that a rectangular groove is formed in a round hole in the upper and lower directions. As in the background art, the distance between the handcart driving rod and the cabinet surface of the circuit breaker of this type is large, and the robot is inconvenient to directly operate, namely, the handcart operating tool is inconvenient to be put on the exposed hexagonal rod, and if the handcart driving hexagonal rod 2 is prolonged and led out by means of a simple tool, the locking structure of the cabinet body can be damaged, so that the rest functions of the cabinet body cannot normally operate.

Example one

As shown in fig. 4 to 7, the operation tool for switching the states of the deep-hole circuit breaker of the embodiment includes a threaded screw rod 5, a support base 6, a locking screw 7, a rotating handle 8, an operating head 9, a guide pin shaft 10, a step screw 11, a bearing end cover 12, a bearing 13, a nut 14, a compression spring 15, and an operation adapting shaft 16,

as shown in fig. 4 and 5, the locking screw 7 is threadedly mounted on the support base 6. A bearing 13 is installed in the supporting seat 6, the outer ring of the bearing 13 is connected with the supporting seat 6, the inner ring of the bearing 13 is matched with a nut 14, the axial movement of the bearing 13 is limited by the step surface of the supporting seat 6 and a bearing end cover 12, and the bearing end cover 12 is fixed on the supporting seat 6 through a screw. The preferred threaded screw rod 5 is provided with a thread characteristic, the thread adopts a fine thread with a self-locking characteristic, and the nut 14 is connected with the threaded screw rod 5 by the thread; the spiral transmission is adopted to overcome the large-load spring at the rear end of the protective sleeve, the operation is simple and labor-saving, the spring can be reversely rotated and released after the task is completed, and the influence on the original locking structure of the cabinet body is avoided; meanwhile, the screw transmission uses fine threads, and the self-locking characteristic is utilized to prevent the task failure caused by the phenomenon of rollback in the task process.

Two guide pin shafts 10 are arranged on a boss feature 6.1 on the supporting seat 6, one end of each guide pin shaft 10 is fixed on the supporting seat 6 through threads, the other end of each guide pin shaft 10 is in clearance fit with a guide groove 5.1 on the threaded screw rod 5, and the rotary nut 14 can realize linear movement of the threaded screw rod 5 along the axial direction through the guide effect of the guide pin shafts 10. The nut 14 is fixed with the rotating handle 8 through a bolt, and the nut 14 can be driven to rotate by rotating the rotating handle 8. The operation transfer shaft 16 is arranged in the threaded screw rod 5, the operation transfer shaft 16 is in clearance fit with the threaded screw rod 5, and the operation transfer shaft 16 can rotate in the threaded screw rod 5. The operating head 9 is mounted on the front end of the operating joint shaft 16, and its position and torque transmission are fixed by a step screw 11. The rear end of the operation transfer shaft 16 and the step surface of the threaded screw rod 5 are provided with a compression spring 15.

As shown in fig. 6, the cabinet surface of the operation tool is fixed. A handcart operation hole 1.1 is formed in a cabinet body cabinet surface 1, rectangular grooves are formed in the upper portion and the lower portion of a round hole of the handcart operation hole, and boss features 6.1 are symmetrically designed on a supporting seat 6 of an operation tool.

When the tool is installed, the rear end of the tool is plugged in from a handcart operation hole 1.1 on a cabinet surface 1, so that boss features 6.1 on a supporting seat 6 pass through a rectangular groove on the handcart operation hole 1.1; the tool is rotated by a certain angle after the tool is rotated, so that the boss features 6.1 are staggered in the rectangular groove, and then the locking screw 7 on the supporting seat 6 is pressed on the cabinet surface, so that the fixture is fixed. The locking screw 7 is provided with a butterfly-shaped handle feature, so that manual screwing is facilitated; and meanwhile, the bottom of the locking screw 7 is provided with a rubber sleeve, so that the cabinet surface is prevented from being scratched when the locking screw is screwed and pressed on the cabinet surface.

Fig. 7 is a schematic sectional view of the operating tool after installation. The specific installation process is as follows:

(1) after the tool is fixed on a cabinet surface, the rotating handle 8 is rotated to drive the nut 14 to rotate, and the threaded screw rod 5 moves towards the interior of the cabinet body along the axial direction through the threaded fit of the nut 14 and the threaded screw rod 5 and the guiding action of the guide shaft pin 10 until the threaded screw rod is contacted with the protective sleeve 3 in the interior of the cabinet body;

(2) the handcart drives the hexagonal rod 2 to be exposed by using the spiral transmission to generate larger thrust with smaller couple to push the protective sleeve 3 to overcome the cabinet body spring 4 to move; the nut 14 and the threaded screw rod 5 are matched by adopting fine threads, so that the self-locking characteristic is realized, and the phenomenon of retraction cannot be generated in the pushing process. When the screw 5 moves, the spring 15 is pushed to drive the operation transfer shaft 16 to move.

(3) The rear end of the operation transfer shaft 16 is provided with a hexagonal hole feature, and when the operation transfer shaft 16 touches the end face of the hexagonal rod 2, the operation transfer shaft 16 does not move inwards any more due to the fact that the hexagonal shaft is not aligned with the hexagonal hole, and meanwhile the spring 15 is compressed.

(4) After the threaded screw rod 5 pushes the protective sleeve 3 to expose the handcart to drive the hexagonal rod 2 to be in place, the rotary operating head 9 drives the operating transfer shaft 16 to rotate for a certain angle, the hexagonal characteristics are aligned, the spring 15 is released, the operating transfer shaft 16 is pushed to be meshed with the handcart to drive the hexagonal rod 2, and at the moment, the operating head 9 is rotated to drive the handcart to drive the hexagonal rod 2 to rotate, so that the circuit breaker is operated.

After the circuit breaker operation is accomplished, need with protective sleeve 3 return, otherwise can destroy the cabinet body from the shutting structure of taking, lead to some function failure of the cabinet body, so the robot operation finishes the circuit breaker task after, need the counter-rotation to rotate handle 8, make protective sleeve 3 return. The rotating handle 8 adopts a handle structure, so that the robot and the manual operation are convenient.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
