Description

A mechanism and method for replacing locking devices in mechanical equipment Technical Field

[0001] This invention belongs to the technical field of locking device replacement for disconnecting switchgear, specifically relating to a mechanical device locking device replacement mechanism and method. Background Technology

[0002] As the market demands higher quality for processed products and users place greater emphasis on product quality and performance, the automatic locking mechanism of disconnecting switchgear becomes particularly important. This is necessary not only to reduce labor costs but also to ensure the effectiveness and quality of screw tightening.

[0003] Currently, for the installation of screws on disconnector switchgear, operators typically tighten them using wrenches. However, due to the small size of the screws, wrenches cannot tighten them completely in one go, making the installation process cumbersome. To improve installation efficiency, long-term observation and research have revealed that using socket wrenches for screw installation can significantly improve efficiency. In this case, screw installation is performed using socket wrenches. However, after prolonged installation, the socket wrenches wear down, resulting in a lack of effective fit with the screws. Replacing the socket wrenches requires multiple pieces of equipment and multiple personnel, increasing replacement costs and failing to achieve the goal of cost reduction and efficiency improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a mechanical equipment locking device replacement mechanism and method to solve the technical defects in the prior art, where after long-term installation, the screw sleeve will wear out, resulting in an inability to effectively cooperate with the screw. When replacing the screw sleeve, it is necessary to use multiple devices and multiple people to complete the replacement, which increases the replacement cost and fails to achieve cost reduction and efficiency improvement.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] In a first aspect, a mechanism for changing locking devices in mechanical equipment is provided, comprising:

[0007] The base has multiple replacement compartments at its ends, and the multiple replacement compartments are used to place the lower parts;

[0008] A lateral adjustment device and a longitudinal adjustment device are disposed on the base. The end of the lateral adjustment device is connected to a pressing device, and the end of the longitudinal adjustment device is connected to a clamping device. The clamping device is located above the pressing device. The clamping device and the pressing device are used to apply force to the upper part.

[0009] An elastic anti-rotation device is provided at the end of the pressing device to limit the rotation of the lower part.

[0010] Furthermore, the base has an installation opening in the middle, and the longitudinal adjustment device is vertically installed in the installation opening and passes through the pressing device to connect with the clamping device.

[0011] One end of the pressing device has a pressing port facing the replacement chamber, and the other end of the pressing device is connected to the lateral adjustment device. The elastic anti-rotation device is set in the pressing port.

[0012] Furthermore, the clamping device has a plate-like structure, and a clamping opening is provided at one end of the clamping device facing the replacement chamber. The clamping opening is located above the pressing port and coincides with the pressing port axially.

[0013] Furthermore, the clamping port has the same structure as the pressing port.

[0014] Furthermore, the clamping port has a structure with one end blocked and the other end open.

[0015] Furthermore, the clamping device is axially perpendicular to the longitudinal adjustment device.

[0016] Furthermore, the elastic anti-rotation device includes a spring pressure plate and an anti-rotation block, wherein the spring pressure plate cooperates with the anti-rotation block;

[0017] Specifically, when the anti-rotation block is not activated, it is in a retracted state; when the anti-rotation block is activated, it is in an extended state.

[0018] Furthermore, the cross-section of the end of the anti-rotation block is arc-shaped.

[0019] Furthermore, the lateral adjustment device is a linear motor, and the longitudinal adjustment device is a cylinder.

[0020] Secondly, a method for replacing a locking device in mechanical equipment is provided, the method being performed using the mechanical equipment locking device replacement mechanism described above, comprising:

[0021] Move the upper and lower parts to be replaced to the top of the base;

[0022] While placing the lower part in the base replacement compartment using external handling equipment, the clamping device clamps the upper part.

[0023] Operate the longitudinal adjustment device to adjust the positional relationship between the upper and lower parts so that the upper and lower parts are in an unlocked or locked state.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. When replacing screw sleeves, the screw sleeve can be divided into an upper part and a lower part. The lower part is placed in a replacement magazine on the base, while the upper part is placed in a clamping device via a handling device. To replace either the upper or lower part, an external drive device rotates the upper part, separating it from the lower part, allowing for easy replacement. This replacement mechanism eliminates manual labor and automates operations between multiple devices, improving replacement efficiency. Furthermore, the inclusion of lateral and longitudinal adjustment devices allows the clamping and pressing devices to move and adjust flexibly in three-dimensional space, further enhancing the level of automated replacement.

[0026] 2. The mounting port in the middle of the base allows the longitudinal adjustment device to be set vertically and connect to the clamping device through the pressing device. This not only saves space but also makes the entire mechanism more compact, improving the space utilization of the equipment. The vertical setting of the longitudinal adjustment device through the mounting port allows the clamping device to move vertically, facilitating precise positioning and clamping of the upper parts.

[0027] 3. The clamping device adopts a plate-like structure, which provides a larger contact area when clamping the upper part, thereby enhancing the stability and reliability of clamping. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0044] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0045] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0046] In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0047] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0048] As the market demands higher quality for processed products and users place greater emphasis on product quality and performance, the automatic locking mechanism of disconnecting switchgear becomes particularly important. This is necessary not only to reduce labor costs but also to ensure the effectiveness and quality of screw tightening.

[0049] Currently, for the installation of screws on disconnector switchgear, operators typically tighten them using wrenches. However, due to the small size of the screws, wrenches cannot tighten them completely in one go, making the installation process cumbersome. To improve installation efficiency, long-term observation and research have revealed that using socket wrenches for screw installation can significantly improve efficiency. In this case, screw installation is performed using socket wrenches. However, after prolonged installation, the socket wrenches wear down, resulting in a lack of effective fit with the screws. Replacing the socket wrenches requires multiple pieces of equipment and multiple personnel, increasing replacement costs and failing to achieve the goal of cost reduction and efficiency improvement.

[0050] To address the aforementioned technical deficiencies, the inventors have provided a mechanism and method for replacing locking devices in mechanical equipment.

[0051] The present invention will now be described in further detail with reference to the accompanying drawings:

[0052] Firstly, as shown in Figures 1-11, this embodiment of the invention provides a mechanical equipment locking device replacement mechanism, including a base 1. As can be seen from Figure 1, the base 1 has a plate-like structure. Replacement compartments 7 are opened at the end of the base 1, and multiple replacement compartments 7 are arranged sequentially at intervals along the length of the base 1. Multiple replacement compartments 7 are used to place lower parts 9. A lateral adjustment device 2 and a longitudinal adjustment device 3 are disposed on the base 1. The end of the lateral adjustment device 2 is connected to a pressing device 5, and the end of the longitudinal adjustment device 3 is connected to a clamping device 4. The clamping device 4 is axially perpendicular to the longitudinal adjustment device 3 and is located above the pressing device 5. The clamping device 4 and the pressing device 5 are used to apply force to the upper parts 8. An elastic anti-rotation device 6 is disposed at the end of the pressing device 5. In this solution, the screw sleeve is divided into upper parts 8 and lower parts 9. During the process of separating and replacing the upper parts 8 and lower parts 9, the elastic anti-rotation device 6 is used to limit the rotation of the lower parts 9 to ensure the reliability of the replacement operation.

[0053] When replacing a screw sleeve, the screw sleeve can be divided into an upper part 8 and a lower part 9. The lower part 9 is placed in the replacement chamber 7 on the base 1, and the upper part 8 is placed in the clamping device 4 by an external handling device (such as a robotic arm). If it is necessary to replace the upper part 8 or the lower part 9, simply connect the external drive device to the top of the upper part 8 and drive the upper part 8 to rotate, thereby separating the upper part 8 from the lower part 9. At this point, the corresponding part can be replaced, such as replacing the upper part 8 or the lower part 9. During the entire replacement process, by using this replacement mechanism to clamp and replace the screw sleeve, manual labor is freed up, and the automated operation between multiple devices improves the replacement efficiency. Secondly, the setting of the lateral adjustment device 2 and the longitudinal adjustment device 3 allows the clamping device 4 and the pressing device 5 to move and adjust flexibly in three-dimensional space, improving the level of automated replacement.

[0054] As shown in Figures 1 and 2, an installation opening is provided in the middle of the base 1. The longitudinal adjustment device 3 is vertically installed in the installation opening and passes through the pressing device 5 and is connected to the clamping device 4. The longitudinal adjustment device 3 is fixedly connected to the pressing device 5, and its driving end is fixedly connected to the clamping device 4 to drive the clamping device 4 to rise and fall. A pressing port is provided at one end of the pressing device 5. The pressing port has a structure with one end open and the other end closed. The open end of the pressing port faces the replacement compartment 7. The other end of the pressing device 5 is connected to the lateral adjustment device 2, which realizes the forward and backward displacement of the pressing device 5. An elastic anti-rotation device 6 is provided in the pressing port. The clamping device 4 has a plate-shaped structure. A clamping port is provided at the end of the clamping device 4 facing the replacement compartment 7. The clamping port is located above the pressing port and coincides with the pressing port axially. As can be seen from the figure, the clamping port and the pressing port have the same structure, both of which are structures with one end closed and the other end open.

[0055] In this scheme, as shown in Figure 10, the elastic anti-rotation device 6 includes a spring pressure plate 601 and an anti-rotation block 602. The spring pressure plate 601 cooperates with the anti-rotation block 602, and the cross-section of the end of the anti-rotation block 602 is arc-shaped. When the anti-rotation block 602 is not activated, it is in a retracted state. When both the upper part 8 and the lower part 9 are placed on the replacement mechanism, the clamping device 4 clamps the upper part 8, the anti-rotation block 602 is activated, and the anti-rotation block 602 is in an extended state. The extended part of the anti-rotation block 602 abuts against the outside of the lower part 9, restricting the rotation of the lower part 9, while the upper part 8 is driven by an external drive device to rotate. The upper part 8 is in a rotating state, and the lower part 9 is in a stationary state. Finally, under the influence of the rotational force, the upper part 8 and the lower part 9 separate, and the corresponding part can be replaced according to the operation.

[0056] In this scheme, the lateral adjustment device 2 is preferably a linear motor, and the longitudinal adjustment device 3 is preferably a cylinder. However, the specific product selection is not limited to this scheme and can be selected according to cost adaptability.

[0057] Secondly, a method for replacing a locking device in mechanical equipment is provided. This method employs the mechanical equipment locking device replacement mechanism described above, as shown in Figure 19, and includes:

[0058] S101. Move the upper and lower parts to be replaced to the top of the base. For example, as shown in FIG3, the upper part 8 and the lower part 9 are clamped and moved to the top of the replacement mechanism by an external robot arm. The axial direction of the upper part 8 coincides with the axial direction of the clamping device 4 and the pressing device 5, and the axial direction of the lower part 9 coincides with the axial direction of the replacement magazine 7. Since the axial direction of the replacement magazine 7 coincides with the axial direction of the clamping device 4, the upper part 8 and the lower part 9 can be assembled together.

[0059] S102. Using external handling equipment, the lower part is placed in the base replacement compartment while the clamping device clamps the upper part. For example, as shown in Figures 4-10, the upper part 8 is placed in the replacement compartment 7. As shown in Figure 5, the upper part 8 includes an upper part body 801. A spring 802 and a sliding sleeve 803 are installed on the outside of the upper part body 801. The spring 802 is connected to the sliding sleeve 803 so that the sliding sleeve 803 can move up and down on the outside of the upper part body 801. The end of the sliding sleeve 803 near the inside of the upper part 8... The upper part extends into the interior of the upper part 8; an elastic block 805 is installed inside the upper part 8, the elastic block 805 is located in the upper middle part of the upper part 8, and positioning posts 806 are provided on opposite sides inside the upper part 8. The positioning posts 806 are used to abut against the positioning post mating point 9011 of the lower part 9, and the locking point 804 is located below the positioning post 806, so that the upper middle part of the lower part 9 is located in the bottom 807 area of ​​the upper part body of the lower part 8; at the same time, a square inner hole 808 is opened inside the upper part 8, and the square inner hole 808 is adapted to the outer side of the lower part 9. As shown in Figure 8, the lower part 9 includes a lower part body 901, which is a rectangular structure. A protrusion 902 is mounted on the top of the lower part body 901, and the outer side of the protrusion 902 has a chamfer 9021. A groove 903 is formed between the lower part body 901 and the protrusion 902, and a frustum 904 is mounted on the bottom of the lower part body 901. As shown in Figure 9, the lower part body 901 is held in place by an external robotic arm and placed in the replacement compartment 7. As shown in Figure 10, the lower part body 901 contacts the anti-rotation block 602. Before the replacement operation begins, the anti-rotation block 602 is in the retracted state 6021. During the replacement operation, the anti-rotation block 602 is in the extended state 6022.

[0060] After the lower part 9 is placed in the replacement compartment 7, as shown in Figures 11 and 12, the clamping device 4 first adjusts the working height through the longitudinal adjustment device 3 so that the clamping port of the clamping device 4 can be at the same height as the outer side of the sliding sleeve 803. Then, the clamping device 4 is driven to move forward through the lateral adjustment device 2 so that the clamping port fits together with the outer side of the sliding sleeve 803, thereby clamping the sliding sleeve 803.

[0061] S103. Operate the longitudinal adjustment device to adjust the positional relationship between the upper and lower parts so that the upper and lower parts are in an unlocked or locked state. For example, as shown in Figures 13-18, when the sliding sleeve 803 is clamped, if the upper part 8 and the lower part 9 are to be replaced, as shown in Figures 13-15, the replaced upper part 8 is pressed down so that the replaced upper part 8 and the replaced lower part 9 are installed together. During the installation process, the lower part body 901 is located in the square inner hole 808, while the protrusion 902 cooperates with the elastic block 805, and the two positioning pins 806 abut against the groove 903, so that the upper part 8 and the lower part 9 are in a locked state. After the replacement is completed, the replacement mechanism is reset, thereby completing the replacement work. As shown in Figures 16-18, when replacing one of the upper part 8 or the lower part 9, the steps are the same as described above. First, the lower part 9 is placed in the replacement compartment 7, and then the anti-rotation block 602 is used to hold the lower part body 901. Next, while the sliding sleeve 803 is held by the clamping device 4, the external drive device drives the upper part body 801 to rotate, thereby realizing the separation between the upper part 8 and the lower part 9.

[0062] In summary, when replacing a screw sleeve, the screw sleeve can be divided into an upper part 8 and a lower part 9. The lower part 9 is placed in the replacement chamber 7 on the base 1, and the upper part 8 is placed in the clamping device 4 by an external handling device (such as a robotic arm). If it is necessary to replace the upper part 8 or the lower part 9, simply connect the external drive device to the top of the upper part 8 and drive the upper part 8 to rotate, thereby separating the upper part 8 from the lower part 9. At this point, the corresponding part can be replaced, such as replacing the upper part 8 or the lower part 9. During the entire replacement process, by using this replacement mechanism to clamp and replace the screw sleeve, manual labor is freed up, and the automated operation between multiple devices improves the replacement efficiency. Secondly, the lateral adjustment device 2 and the longitudinal adjustment device 3 enable the clamping device 4 and the pressing device 5 to move and adjust flexibly in three-dimensional space, improving the level of automated replacement. Furthermore, the replacement structure in this solution can be used not only for replacing screw sleeves, but also for replacing other parts with screw connections, snap-fit ​​connections, and plug-in assembly.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit its scope of protection. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading the present invention, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the invention, but these changes, modifications or equivalent substitutions are all within the scope of protection of the pending claims of the invention.
