Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] The present invention will now be described in detail.

[0020] like Figures 1-10 As shown: An operation and maintenance device applicable to various types of ATS equipment includes a mounting part 1, multiple sets of detachable operating tools 2 mounted on the mounting part 1 for maintenance of different types of ATS equipment, and a locking member 3 for locking each set of operating tools 2 to the mounting part 1 and mounted on the mounting part 1. The mounting part 1 is made of plastic and can be manufactured using 3D printing technology. It includes a ring-shaped mounting base 11 and multiple sets of mounting posts 12 arranged on the outside of the mounting base 11 for mounting the operating tool 2. Multiple sets of mounting posts 12 are evenly arranged around the circumference of the mounting base 11; mounting holes 120 are provided on the mounting posts 12 and along their axial direction.

[0021] This utility model integrates and assembles multiple sets of operating tools 2 for the maintenance of different types of ATS equipment using the mounting part 1, thereby enabling better storage and avoiding the loss of operating tools 2 due to the large number of different types of ATS equipment; preferably, the mounting base 11 is in the shape of a ring; since the mounting base 11 is in the shape of a ring, it is easy to hang and store, making storage simple and convenient, and facilitating tool management; When performing maintenance using this utility model, since the operation and maintenance devices for different types of ATS equipment are integrated together, maintenance personnel can directly take this device to the site for maintenance. This avoids the situation where the operation and maintenance device for a certain type of ATS equipment is omitted, resulting in the inability to perform maintenance on site, and greatly improves maintenance efficiency. In this utility model, the operating tool 2 is detachably connected to the mounting part 1, so that the operating tool 2 that meets the requirements can be installed according to the change of ATS equipment type. During assembly, the operating tools 2 of multiple sets of different types of ATS equipment corresponding to this project are installed on the mounting part 1, and then the locking parts 3 are used to lock and fix each set of operating tools 2 to the mounting column 12. When in use, the appropriate operating tool 2 can be selected for maintenance according to the type of ATS equipment.

[0022] In some possible implementations, in order to effectively achieve a detachable connection between the mounting post 12 and the operating tool 2, the mounting post 12 includes a body 121 with one end connected to the mounting base 11, and a connecting post 122 disposed on the body 121 and provided with a mounting hole 120; the mounting hole 120 is a blind hole, and the operating tool 2 can be detachably inserted into the mounting hole 120.

[0023] In some possible implementations, in order to effectively lock and fix the operating tool 2 to the mounting part 1 by means of the locking member 3, and to prevent the operating tool 2 from moving under the action of external force during use, the locking member 3 includes an abutment member 31 that is fitted on the outside of the connecting post 122 and elastically connected to the body 121, a limiting block 32 that is slidably installed in the connecting post 122 and has one end extending into the mounting hole 120 to be inserted and engaged with the operating tool 2, and a through groove 33 that is provided on the connecting post 122 and communicates with the mounting hole 120, wherein the limiting block 32 is installed in the through groove 33 and slidably engaged with the through groove 33; With the above configuration, since the abutment 31 is elastically connected to the body 121 and slides along the axial direction of the body 121, during assembly, the abutment 31 is controlled to move closer to the body 121, so that the limiting block 32 is not restricted by the abutment 31 and can slide along the length direction of the through groove 33. Then, one end of the operating tool 2 is inserted into the mounting hole 120. During the insertion process, the operating tool 2 will abut against the limiting block 32 on the side of the mounting hole 120 and apply a force to it to move away from the mounting hole 120, so that the operating tool 2 can be successfully inserted. After insertion, under the action of elastic restoring force, the abutment 31 moves away from the body 121 and applies force to the limiting block 32 away from the mounting hole 120, so that the limiting block 32 moves into the mounting hole 120, so that the end of the limiting block 32 near the mounting hole 120 abuts against the outside of the operating tool 2, thus fixing the operating tool 2.

[0024] In some possible implementations, to prevent the abutment 31 from moving freely on the connecting post 122, a limiting boss 1221 is provided at the end of the connecting post 122 away from the body 121, and the abutment 31 is located between the limiting boss 1221 and the body 121; specifically, after assembly is completed, under the elastic force, the abutment 31 moves towards the limiting boss 1221, and its top surface abuts against the bottom of the limiting boss 1221, restricting the free movement of the abutment 31 and preventing the phenomenon of insecure locking. Preferably, when the abutting member 31 abuts against the limiting boss 1221, the abutting member 31 is in a compressed or initial state.

[0025] In some possible implementations, in order to effectively lock and fix the operating tool 2 by means of the abutment 31, the abutment 31 includes an upper cover 311 that is fitted on the outside of the connecting post 122 and abuts against the bottom of the limiting boss 1221, a limiting sleeve 312 that is provided on the side of the upper cover 311 near the body 121 and fitted on the outside of the connecting post 122, and a spring 313 that is fitted on the outside of the limiting sleeve 312 and connected to the upper cover 311 and the body 121 respectively. An annular groove 3121 is provided on the inner side of the limiting sleeve 312 and the side near the upper cover 311 to cooperate with the limiting block 32; Specifically, during assembly, the top cover 311 moves toward the side closer to the body 121, while simultaneously moving the limiting sleeve 312 and the annular groove 3121 until the annular groove 3121 connects with the through groove 33 and the limiting block 32 can enter the annular groove 3121. At this time, the spring 313 is compressed; then the operating tool 2 is inserted. After the operation is completed, the upper cover 311 is no longer under force, the spring 313 moves away from the body 121, and the limiting block 32 located in the annular groove 3121 will move towards the mounting hole 120 under the drive of the annular groove 3121, so that the limiting block 32 close to the mounting hole 120 abuts against the operating tool 2. The outer side of the limiting block 32 will contact and abut against the inner side of the limiting sleeve 312, thereby locking and fixing the operating tool 2. Furthermore, the outer side of the limiting block 32 is coplanar with the outer side of the connecting post 122 after assembly; preferably, the connecting post 122 has a cylindrical structure, and a lower cover for connecting with the spring 313 is provided on the side of the connecting post 122 near the body.

[0026] In some possible implementations, the annular groove 3121 has a U-shaped structure with its opening located on the side near the mounting hole 120; the side of the annular groove 3121 near the body 121 is an inclined surface 31211; the size of the opening side of the annular groove 3121 is larger than the size of its opposite side; here, the opposite side is the side opposite to the opening side; a small inclined surface 323 matching the inclined surface 31211 is provided on the bottom of the limiting block 32 near its outer side. When the annular groove 3121 moves away from the body 121, due to the inclined setting, the limiting block 32 moves towards the mounting hole 120 side, and the inclined surface 31211 will separate from the state of contact with the small inclined surface 323, driving the limiting block 32 to slide towards the mounting hole 120 side.

[0027] In some possible implementations, to prevent the limiting block 32 from moving freely within the through groove 33 and falling into the mounting hole 120, a limiting member is provided within the through groove 33 to restrict the limiting block 32 from falling into the mounting hole 120.

[0028] Specifically, the limiting component includes a limiting platform disposed in the through groove 33 and a limiting groove 34 disposed on the limiting block 32 and slidingly engaged with the limiting platform to limit the sliding of the limiting block 32; the length direction of the limiting groove 34 is arranged along the sliding direction of the limiting platform, and it has an opening on the side near the mounting hole 120. When the limiting block 32 slides toward the mounting hole 120, when the limiting platform contacts and abuts the bottom of the limiting groove 34, the limiting block 32 will no longer be able to slide into the mounting hole 120, thereby preventing the limiting block 32 from falling into the mounting hole 120; Of course, a limiting groove 34 can also be set in the through groove 33. In this case, the opening of the limiting groove 34 will be set on the side away from the mounting hole 120, and the limiting platform will be set on the limiting block 32 and slide in cooperation with the limiting groove 34. When the limiting platform contacts and abuts the bottom of the limiting groove 34, the sliding of the limiting block 32 can also be restricted.

[0029] In some possible implementations, the mounting posts 12 are in three groups and are equally spaced along the circumference of the mounting base 11, and the cross-section of the mounting hole 120 is polygonal; that is, the axes of the three groups of mounting posts 12 are arranged radially along the annular mounting base 11, and the included angle formed between two adjacent groups of mounting posts 12 is 120°. Specifically, the mounting hole 120 has a regular polygonal structure, such as a square, a regular hexagon, etc. With this setting, when using the tool 2, it will rotate and slip around the axis of the mounting post 12 within the mounting hole 120, thus avoiding affecting normal use.

[0030] In some possible implementations, the operating tool 2 includes an insert post 21 inserted into the mounting hole 120 and used in conjunction with the locking member 3, and an operating head 22 mounted on the insert post 21; the insert post 21 is provided with a limiting slot 211 that corresponds one-to-one with and is used in conjunction with the limiting block 32. The limiting slot 211 has a figure-eight structure, with an opening at its large end; Specifically, such as Figures 7-9 As shown, the operating head 22 can be a regular polygonal structure, a cylindrical structure, a flat-mouthed structure, etc., as long as it is compatible with the ATS device; for example... Figure 9 As shown, the operating head 22 with a regular polygonal structure is used in conjunction with an ATS device having a regular polygonal slot; as Figure 7 As shown, the operating head 22 with a cylindrical structure is used in conjunction with an ATS device having a cylindrical concave shape; as Figure 8 As shown, the flat-mouthed operating head 22 is used in conjunction with an ATS device having a flat-mouthed groove.

[0031] During assembly, the insert post 21 is inserted into the mounting hole 120, at which time the limiting slot 211 will be set to correspond with the through slot 33; under the restoring force of the spring 313, the abutment 31 will move away from the body 121, causing the limiting block 32 to move closer to the limiting slot 211. When the limiting block 32 abuts against the limiting slot 211, the outer side of the limiting block 32 will also abut against the inner side of the limiting sleeve 312.

[0032] In some possible implementations, an upper inclined surface 321 for use with the insert post 21 is provided on the top surface of the limiting block 32, and a lower inclined surface 322 is provided at the bottom of the limiting block 32; the upper inclined surface 321 and the lower inclined surface 322 form a figure-eight structure and their small ends are located on the side close to the mounting hole 120. In use, the end of the limiting block 32 away from the spring 313 abuts against the bottom of the limiting slot 211.

[0033] The figure-eight structure formed by the upper inclined surface 321 and the lower inclined surface 322 will be located in the limiting slot 211 after the limiting block 32 comes into contact with the insert post 21; This is achieved through the cooperation of two sets of eight-group inclined planes 31211: During assembly, the control cover 311 moves towards the side closer to the body 121, and the annular groove 3121 and the through groove 33 are connected in corresponding positions; the insert post 21 is inserted into the mounting hole 120, and the insert post 21 applies force to the upward inclined surface 321, causing the limiting block 32 to slide into the annular groove 3121 away from the mounting hole 120, thus avoiding the movement of the insert post 21 towards the side closer to the body 121; During disassembly, the control cover 311 moves towards the side closer to the body 121, the annular groove 3121 corresponds to the through groove 33, and the insertion post 21 is pulled outward from the mounting hole 120. At this time, the insertion post 21 will apply force to the downward inclined surface 322, causing the limiting block 32 to slide away from the mounting hole 120 and enter the annular groove 3121 to avoid the movement of the insertion post 21 away from the body 121.

[0034] Preferably, the limiting slots 211 are arranged in multiple sets and evenly on the outer side of the insert post 21, and the number of through slots 33 and limiting blocks 32 is the same as the number of limiting slots 211 and they are arranged in a one-to-one correspondence. Specifically, when the mounting hole 120 is a regular square, the insert post 21 is a regular square prism, and two sets of limiting slots 211 can be set; when the mounting hole 120 is a regular hexagon, the insert post 21 is a regular hexagon, and three sets of limiting slots 211 can be set.

[0035] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
