Technical Field

[0001] This utility model belongs to the field of power maintenance technology, specifically relating to a multi-functional operating tool. Background Technology

[0002] Switchgear is one of the main pieces of equipment in a power distribution room. It requires regular inspection, maintenance, repair, replacement, and testing. This generally includes rotating the switch to confirm its smooth operation; unlocking the cabinet door, opening the cabinet door, and moving the handcart circuit breaker inside the cabinet to the test position for inspection and electrical testing.

[0003] Currently, multiple operating tools are required to operate the rotating switch and unlock the cabinet door. Moreover, opening the cabinet door generally requires the operator to manually open it at close range. The inspection robot needs to frequently change and retrieve different operating tools, which is cumbersome. This not only increases the maintenance time, but also requires the robot to carry and be equipped with a variety of operating tools, thus increasing the manufacturing cost. Utility Model Content

[0004] This utility model provides a multi-functional operating tool, which aims to solve the problem of frequently changing operating tools with different functions, which is time-consuming, labor-intensive, and increases manufacturing costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a multifunctional operating tool, comprising: The tool body has a hollow cavity; The unlocking operation assembly includes a geared motor installed in the hollow cavity of the tool body, a transmission rod connected to the main shaft of the geared motor, and an unlocking head installed at the front end of the transmission rod; the unlocking operation assembly is used to open the lock on the door handle or cabinet door; The door handle opening and closing operation assembly includes a first swing block, a second swing block, and a support arm installed at the front end of the tool body. The first swing block and the second swing block are staggered to clamp the two sides of the door handle. When the first swing block and the second swing block are clamped on the two sides of the door handle, the support arm serves as a fulcrum to support the cabinet door. The door handle is opened by rotating the tool body. A cabinet door opening arm, mounted on the front end of the tool body, is used to open or close the unlocked cabinet door; and A quick-change gripper is installed at the rear end of the tool body for rapid exchange with the robot's robotic arm.

[0006] In one possible implementation, the tool body includes a protective sleeve and a flange sleeve fixed to the front end of the protective sleeve, the transmission rod passes through the central hole of the flange sleeve, and the unlocking head protrudes outside the flange sleeve; The door handle opening and closing operation assembly and the cabinet door opening arm are both fixed to the side of the flange sleeve; The quick-change clamp is installed at the rear end of the protective sleeve.

[0007] In one possible implementation, the operating tool further includes a switch-operating assembly for turning the switch, which includes a guide slider and a spring. The guide slider is slidably fitted within the central hole of the flange sleeve, and the spring is connected between the rear end of the guide slider and the front stop plate of the protective sleeve. Symmetrically arranged turning blocks are provided on the front end face of the guide slider, and a gap is formed between the two turning blocks to clamp the switch-operating device. The guide slider has a central hole through which the transmission rod passes. When it is necessary to open the circuit breaker switch, simply align the gap between the two screw blocks with the circuit breaker switch and screw it in. When unlocking the lock, the unlocking head is aligned with the key hole on the cabinet door. The front end of the rotating block first contacts the cabinet door and then compresses the spring backward under the continuously applied external force until the unlocking head is inserted into the lock.

[0008] In one possible implementation, the inner side of the screw block is provided with an arc-shaped guide slope, which guides the unlocking head to align itself with the lock hole on the cabinet door when the arc-shaped guide slope contacts the outer frustum of the lock hole.

[0009] In one possible implementation, the support arm is provided with forward-protruding ball bearings; when the door handle is opened, the ball bearings act as a fulcrum to support the cabinet door.

[0010] In one possible implementation, the opening and closing changeover switch turning operation group further includes a travel limit post that limits the travel of the guide slider. The guide slider is provided with a travel groove along its moving direction, and the travel limit post is installed on the flange sleeve and extends into the travel groove. When the guide slider moves backward to the front end of the travel groove and abuts against the travel limit post, the unlocking head is exposed; When the guide slider moves forward until the rear end of the travel groove abuts the travel limit post, the unlocking head is hidden inside the screw block.

[0011] In one possible implementation, the guide slider has stroke grooves on its opposite two sides, and the flange sleeve has corresponding stroke limit posts.

[0012] In one possible implementation, the cross-section of the guide slider is quadrilateral, and the center hole of the flange sleeve is a quadrilateral hole adapted to the guide slider to form an anti-rotation structure. The cross-section is perpendicular to the direction of movement of the guide slider.

[0013] In one possible implementation, the guide slider has a toothed groove on the side that mates with the flange sleeve. The length of the toothed groove extends along the moving direction of the guide slider, and the toothed groove is evenly distributed around the four sides of the guide slider.

[0014] Compared with the prior art, the multifunctional operating tool provided by this utility model has the following advantages: The multifunctional operating tool provided by this application integrates the locking and unlocking of the cabinet door or door handle, the opening of the door handle, and the opening or closing of the cabinet door after unlocking. It combines multiple functions into one tool. When the inspection robot docks with the multifunctional operating tool, it can realize the actions of unlocking the cabinet door, opening the door handle, and opening the cabinet door. There is no need to frequently change the operating tool. This not only saves maintenance time, but also reduces the material and labor costs required for repeated production of operating tools. Furthermore, it can save storage space for different operating tools and facilitate the miniaturization of storage space design.

[0015] When using an inspection robot to inspect switchgear, the robot's robotic arm connects to a multi-functional operating tool. The robotic arm drives the unlocking head to align with the keyhole on the door handle, and then starts the geared motor to rotate the unlocking head, which can open the lock on the door handle. Reverse rotation can lock the lock. Then, the robotic arm uses the first and second swing blocks of the door handle opening and closing operation group to insert into both sides of the door handle, with the support arm supporting the cabinet door. By rotating the robotic arm, the door handle can be rotated to open, or rotated in the opposite direction to close. The robotic arm drives the cabinet door opening arm to insert into the gap between the cabinet door and the cabinet body, and then pulling the cabinet door can open the cabinet door. At the same time, the cabinet door opening arm can be used to push the cabinet door to close it.

[0016] This allows for the continuous unlocking, opening of door handles, and opening of cabinet doors, which can shorten maintenance time, improve maintenance efficiency, avoid the safety risks of personnel operating close to the cabinet, reduce manufacturing costs and storage space, facilitate the miniaturization of storage space, and further reduce material usage costs.

[0018] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Please refer to the following: Figures 1 to 15The multifunctional operating tool provided by this utility model will now be described. The multifunctional operating tool includes a tool body, an unlocking operating assembly, a door handle opening and closing operating assembly, a cabinet door opening arm 5, and a quick-change clamp 1. The tool body has a hollow cavity, which provides protection for the geared motor 20, transmission rod 13, etc., and provides support for the entire tool.

[0020] See Figures 1 to 6 , Figure 13 and Figure 14 The unlocking operation group includes a geared motor 20 installed in the hollow cavity of the tool body, a transmission rod 13 connected to the main shaft of the geared motor 20, and an unlocking head 9 installed at the front end of the transmission rod 13; the unlocking operation group is used to open the lock on the door handle or cabinet door 23; wherein, the lock can be a 705-2 door lock.

[0021] The geared motor 20 provides power for the rotation of the unlocking head 9. The transmission rod 13 is connected to the main shaft of the geared motor 20 via a spline sleeve 18. There are also mating ribs and grooves between the unlocking head 9 and the transmission rod 13 to facilitate power transmission. This connection is a conventional technical method and will not be described in detail here.

[0022] The door handle opening and closing operation assembly includes a first swing block 11, a second swing block 12 and a support arm 6 installed at the front end of the tool body. The first swing block 11 and the second swing block 12 are staggered and clamped on both sides of the door handle. When the first swing block 11 and the second swing block 12 are clamped on both sides of the door handle, the support arm 6 serves as a fulcrum to support the cabinet door 23 and rotates to open the door handle.

[0023] The cabinet door opening arm 5 is installed at the front end of the tool body to open or close the unlocked cabinet door 23.

[0024] The quick-change fixture 1 is a universal component that docks with the robot's robotic arm. It is installed at the rear end of the tool body and is used for quick exchange with the robot's robotic arm.

[0025] Compared with the prior art, the multifunctional operating tool provided by this utility model has the following advantages: The multifunctional operating tool provided by this application integrates cabinet door unlocking, door handle opening, and opening or closing tools after cabinet door unlocking, combining multiple functions into one tool. When the inspection robot is connected to a multifunctional operating tool, it can realize the actions of cabinet door unlocking, door handle opening, and cabinet door opening without frequent replacement of operating tools. This not only saves maintenance time, but also reduces the material and labor costs required for repeated production of operating tools. Furthermore, it can save storage space for different operating tools and facilitate the miniaturization design of storage space.

[0026] When using an inspection robot to inspect switchgear, the robot's robotic arm connects to a multi-functional operating tool. The robotic arm drives the unlocking head 9 to align with the keyhole on the door handle, and then the reduction motor 20 is started to rotate the unlocking head 9 to open the lock on the door handle. Reverse rotation will lock the lock. Then, the robotic arm inserts the first swing block 11 and the second swing block 12 of the door handle opening and closing operation group into both sides of the door handle. The support arm supports the cabinet door, and the door handle can be rotated to open or rotated to close by rotating it in the opposite direction. After the cabinet door is unlocked, the robotic arm drives the cabinet door opening arm 5 to insert into the handle on the cabinet door or into the gap between the cabinet door and the cabinet body. Pulling the cabinet door will open it, and pushing the cabinet door with the cabinet door opening arm 5 will close it.

[0027] This allows for continuous unlocking, opening, and rotary switch operations, which shortens maintenance time, improves maintenance efficiency, avoids the safety risks of personnel operating close to the cabinet, reduces manufacturing costs and storage space, facilitates miniaturization of storage space, and further reduces material usage costs.

[0028] In some embodiments, see Figures 1 to 6 As shown, the tool body includes a protective sleeve 3 and a flange sleeve 4 fixed to the front end of the protective sleeve 3. The transmission rod 13 passes through the center hole of the flange sleeve 4, and the unlocking head 9 protrudes outside the flange sleeve 4 (see...). Figure 2 Flange sleeve 4 provides support for the door handle opening and closing operation assembly and the cabinet door opening arm 5; a flange sleeve is provided at the rear end of flange sleeve 4, and the flange sleeve and the front end of protective sleeve 3 are connected together by bolts.

[0029] The door handle opening and closing assembly and the cabinet door opening arm 5 are both fixed to the side of the flange sleeve 4; the quick-change clamp 1 is installed at the rear end of the protective sleeve 3. Among them, a connecting plate 2 is provided at the rear end of the protective sleeve 3, and the connecting plate 2 is connected to the rear end of the protective sleeve 3 by bolts. The quick-change clamp 1 is fixed to the connecting plate 2 by bolts.

[0030] It should be explained that, as defined in this application, the front end refers to the end closer to the switchgear, and the rear end refers to the end farther away from the switchgear.

[0031] In some embodiments, see Figures 1 to 6 The operating tools also include a switch turning operation assembly, which includes a guide slider 8 and a spring 17. The guide slider 8 is slidably fitted in the center hole of the flange sleeve 4. The spring 17 is connected between the rear end of the guide slider 8 and the front baffle 19 of the protective sleeve 3. Symmetrically arranged turning blocks 10 are provided on the front end face of the guide slider 8, and the gap between the two turning blocks 10 forms a gap for clamping the switch. The guide slider 8 is provided with a center hole through which the transmission rod 13 passes.

[0032] When it is necessary to open the circuit breaker switch, simply align the gap between the two rotating blocks 10 with the circuit breaker switch and turn it. Therefore, this application also has the function of opening the circuit breaker switch, including opening the door handle, unlocking the lock, and opening the cabinet door, thus having multiple functions.

[0033] When unlocking the lock, the unlocking head 9 is aligned with the keyhole on the cabinet door. The front end of the turning block 10 first contacts the cabinet door and, under continuous external force, compresses the spring 17 backward until the unlocking head 9 is inserted into the lock (see...). Figure 2 At this point, the geared motor 20 drives the unlocking head 9 to rotate, enabling unlocking and locking operations. When the robotic arm moves the operating tool backward, the external force applied to the turning block 10 disappears. When the turning block 10 is no longer in contact with the cabinet door, the spring 17 resets and pushes the guide slider 8 forward. The turning block 10 continues to surround the unlocking head 9, thus protecting the unlocking head 9 (see...). Figure 1 This avoids the risk of the lock pick 9 being bumped or scratched when handling the operating tools.

[0034] In this application, the unlocking head 9 has a straight-line structure, and the matching lock hole is a straight-line hole, such as the 705-2 door lock.

[0035] In some embodiments, see Figure 4 As shown, the inner side of the screw block 10 is provided with an arc-shaped guide slope 15. When the arc-shaped guide slope 15 contacts the outer frustum of the lock hole (set on the cabinet door), it guides the unlocking head 9 to align itself with the lock hole on the cabinet door. The purpose of this embodiment is mainly to solve the problem that when the robotic arm operated by the robot cannot accurately align the unlocking head 9 with the lock hole, the unlocking head 9 will be scratched and damaged, making it impossible to unlock.

[0036] In the above technical solution, when the unlocking head 9 deviates from the lock hole during alignment, since the turning block 10 first contacts the outer truncated cone of the lock hole, the arc-shaped guide slope 15 set on the inner side of the turning block 10 will contact the outer truncated cone. At this time, the continued pressure will cause the turning block 10 to slide along the outer truncated cone, which can guide the unlocking head 9 to align with the lock hole on the cabinet door, thus avoiding the problem that the unlocking head 9 cannot be directly aligned with the lock hole.

[0037] Therefore, it can be seen that the rotary operation group of the circuit breaker not only has the function of opening the circuit breaker, but also has the function of opening the lock in conjunction with the unlocking head.

[0038] In some embodiments, see Figures 1 to 3 The support arm 6 is provided with a forward-protruding ball bearing 7; when unlocking, the ball bearing 7 contacts the cabinet door before the rotating block 10, and is subjected to a continuous external force to press against the cabinet door 23, providing a fulcrum for the door handle to improve the stability of the action.

[0039] The advantage of using ball bearing 7 for support in the above solution is that ball bearing 7 and cabinet door form rolling friction. Especially when the unlocking head 9 and the key hole are not aligned, the tool as a whole needs to be moved and adjusted. Therefore, when ball bearing 7 is supported on the cabinet door, it can also rotate with the movement of the tool to improve the flexibility of the tool's movement when the unlocking head 9 is aligned.

[0040] To facilitate understanding of the operation process, the lock hole structure on the switchgear is further explained as follows: Since the safety of the cabinet door on the switchgear is crucial, in order to avoid accidental contact with the lock hole, a recess is generally provided on the cabinet door. An outer truncated cone is provided in the recess, and the end face of the outer truncated cone is lower than the surface of the cabinet door, that is, the outer truncated cone is recessed in the recess. The lock hole is located in the center of the outer truncated cone. A lock cover is provided on the recess to cover and conceal the lock hole, so as to prevent the lock hole from being exposed. The outer boundary of the screw block 10 does not exceed the inner wall boundary of the recess. When the unlocking head 9 approaches the lock hole, the screw block 10 is also inserted into the recess, and the front end face of the screw block 10 will contact the end face of the outer truncated cone.

[0041] In some embodiments, see Figure 4 and Figure 6 , Figure 7 The opening and closing switch turning operation group also includes a travel limit post 14 that limits the travel of the guide slider 8. The guide slider 8 is provided with a travel groove 16 along its moving direction. The travel limit post 14 is installed on the flange sleeve 4 and extends into the travel groove 16. The travel limit post 14 can be a bolt, which is directly screwed into the threaded hole 22 provided on the flange sleeve 4.

[0042] The travel limit post 14 can also be a light shaft with an anti-detachment cap. A shaft retaining ring is set on the light shaft, and the anti-detachment cap is used to restrict the travel limit post 14 to the flange sleeve 4.

[0043] When the guide slider 8 moves backward to the front end of the travel groove 16 and abuts against the travel limit post 14, the exposed unlocking head 9 (see...) Figure 2 When the guide slider 8 moves forward until the rear end of the stroke groove 16 abuts against the stroke limit post 14, the unlocking head 9 is hidden inside the turning block 10 (see...). Figure 1 ).

[0044] In the above technical solution, the combination of the stroke groove 16 and the stroke limit post 14 can limit the position of the guide slider 8 moving forward and backward. This mechanical limit can prevent the guide slider 8 from moving too far forward or backward when the electronic control fails.

[0045] In some embodiments, see Figure 4 The guide slider 8 has stroke grooves 16 on its two opposite sides, and corresponding stroke limit posts 14 are provided on the flange sleeve. The stroke limit posts on both sides ensure the smoothness and consistency of the guide slider 8's forward and backward movement.

[0046] In some embodiments, see Figures 7 to 12 The cross-section of the guide slider 8 is quadrilateral, and the center hole of the flange sleeve 4 is a quadrilateral hole that fits the guide slider 8 to form an anti-rotation structure. Through the cooperation between the quadrilateral guide slider 8 and the quadrilateral hole, the self-anti-rotation function of the guide slider 8 can be realized, preventing the guide slider 8 from rotating and ensuring that the guide slider 8 can only move linearly back and forth in the front and back directions.

[0047] In this embodiment, the cross-section is perpendicular to the direction of movement of the guide slider 8.

[0048] In some embodiments, see Figures 7 to 9 The guide slider 8 has a toothed groove 21 on its side where it mates with the flange sleeve 4. The toothed groove 21 extends along the moving direction of the guide slider 8 and is evenly distributed around the four sides of the guide slider 8. The purpose of providing the toothed groove 21 on the side of the guide slider 8 is to reduce the contact area between the guide slider 8 and the flange sleeve 4, thereby reducing sliding friction and making the guide slider move back and forth flexibly, reducing frictional resistance.

[0049] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
