Description

Technical Field

[0001] The invention belongs to the technical field of wiring robots, and in particular relates to an auxiliary wiring robot for on-site verification of current transformers. Background Art

[0002] With the implementation of power grid transformation, a large number of current sensors and transmitters are widely used in power systems. As a necessary metering device for electric energy settlement, the transformer plays an important role in the power system. Its accuracy and reliability are directly related to whether the power system can operate safely and stably. According to relevant laws and regulations such as "JJG313-2010 Verification Procedure for Current Transformers for Measurement", the power department should enforce on-site verification of electric energy metering devices, including transformers, electric energy meters and secondary circuits, to protect the interests of both the supply and demand sides of electric energy. The on-site verification of the current transformer is to connect the wiring port of the current transformer to be tested with the port of the standard current transformer, and then verify the current transformer to be tested at high altitude through the verification circuit composed of instruments such as current booster, voltage stabilizer, load box, and verification instrument.

[0003] At present, there are two main methods to connect the wiring port of the current transformer under test with the standard current transformer port: one is to manually connect the transformer input and output ports with bolts, and the other is to use copper clamps to clamp the transformer ports. However, both methods require the construction of scaffolding or the use of cranes to enable workers to reach the high-altitude platform to complete the wiring. The biggest disadvantage is that the safety hazard is large, the labor intensity is high, the task is complex, and it is difficult to popularize all power grids.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Through the integrated application of components such as magnetic devices and cameras, automatic selection and status monitoring of pre-wiring are realized. In this process, the magnetic device uses electromagnets to absorb the pre-wiring, while the camera is responsible for capturing the status information of the pre-wiring, such as whether it is damaged or bent. In addition, the pressure sensor can also detect whether the pre-wiring has been correctly placed in the predetermined position. This combination not only ensures the quality of the pre-wiring, but also monitors the entire wiring process in real time, and promptly detects and handles potential problems. Ultimately, the beneficial effects of ensuring wiring quality and improving fault response speed are achieved.

[0017] 2. Precise movement and positioning of the pre-wires are achieved through precise control of the clamping claw cylinder. When the pre-wires need to be moved from the storage device to the pre-connection position of the current transformer, the clamping claw cylinder will first clamp the slot on the tensioner, and then the pre-wires will be accurately placed in the designated position through the coordinated action of the robotic arm. This process not only reduces the time of manual operation, but also greatly improves the accuracy of wiring and avoids errors caused by human factors. This realizes the automated wiring process and improves the efficiency and quality of on-site operations.

[0018] 3. Through the design of the tensioning device, the pre-wired wiring is stably clamped and released. In specific operation, when the tensioning rod is under pressure, it compresses the spring downward and drives the tension sleeve to move downward along the tapered part of the tensioning seat, thereby reducing the diameter of the tension sleeve and ensuring that the pre-wired wiring can be tightly and firmly clamped. The role of this step is to ensure that the pre-wired wiring will not loosen or fall off during the transmission process, and improve the safety and reliability of the wiring process. Ultimately, the beneficial effect of improving work efficiency and reducing the risk and cost of manual intervention is achieved.

[0039] The magnetic device 8 includes a rectangular block 81, which is connected to the mounting frame 4 by screws. A second cylinder 83 is fixedly connected to the upper part of the rectangular block 81, and a pre-wiring support seat 82 is fixedly connected to the upper part of the telescopic rod of the second cylinder 83.

A pressure sensor 86 is embedded in the semicircular groove 84, and a camera 87 is embedded in the rectangular groove 85.

[0040] It also includes a traveling lifting vehicle 7, the lower part of which is provided with wheels, the upper part of which is connected to a turret 9, the upper part of which is connected to a vertical lifting arm 10, the top of which is connected to a lateral extension arm 11, and the end of which is connected to an equipment installation platform 12.

[0041] A safety guardrail 14 is fixedly connected to the equipment installation platform 12, a Y-axis screw conveyor 15 is fixedly connected to the top of the safety guardrail 14, an X-axis screw conveyor 16 is fixedly connected to the lower part of the slide of the Y-axis screw conveyor 15, and a linear cylinder 21 is fixedly connected to the lower part of the slide of the X-axis screw conveyor 16.

[0042] The lower end of the telescopic rod of the linear cylinder 21 is fixedly connected to the rotary cylinder 2, and the rotating end of the rotary cylinder 2 is fixedly connected to the clamping cylinder 3. The X-axis screw conveyor 16 and the Y-axis screw conveyor 15 are respectively connected to the DC motor 20.

[0043] A protruding connection portion 18 is welded to the right side of the equipment installation platform 12 , and an equipment installation bracket 17 is welded to the lower part of the equipment installation platform 12 .

[0044] Working principle: When in use, prepare multiple sets of workpieces such as tensioning device 5, pre-wired wire 6, locking nut 53 and tensioning sleeve 56, and place them on the storage device of the equipment installation platform 12;

[0045] At this time, the X-axis screw conveyor 16 and the Y-axis screw conveyor 15 can drive the clamping cylinder 3 to move, the first cylinder 30 can drive the piston rod 28 to extend, and the umbrella-shaped suction cup 272 on the material taking device 27 can absorb the locking nut 53 on the storage device and place it inside the hexagonal sleeve 22;

[0046] When the magnetic device 8 is moved to the storage device, it can absorb the pre-wire 6 through the electromagnet 88 and confirm the position through the camera 87 and the pressure sensor 86, so that the opening on the conductive connecting plate 61 is aligned with the opening of the locking nut 53.

[0047] The connecting column 271 and the magnet on the material taking device 27 can absorb the tensioning device 5 on the storage device. The piston rod 28 drives the tensioning device 5 to enter the interior of the rotating sleeve 25 during the downward movement. At this time, the driving motor 31 can drive the first gear 19 to rotate, and then drive the circular sleeve 24 and the rotating sleeve 25 to rotate, so as to lock the locking nut 53 to the tensioning seat 54 through the thread.

[0048] The tensioning state of the tensioning sleeve 56 is controlled by compressing the spring 52 through the tensioning rod 51 , and the clamping jaws 301 on the clamping jaw cylinder 3 move toward each other under the command of the control system, and clamp the tensioning seat 54 through the semicircular notch on the extension block 1 .

[0049] Subsequently, the material taking device 27 contacts and presses down the tensioning rod 51, compressing the spring 52, causing the tensioning sleeve 56 to slide down along the conical surface of the tensioning seat 54, thereby restoring to the initial non-expanded state, that is, the flap 562 rotates under the action of the conical surface to be parallel to the cylinder 563, so that it no longer flips outward.

[0050] The tension rod 51 and the spring 52 are designed as a combination. In the pre-connection position, the tension sleeve 56 is sent to the pre-connection thread groove of the current transformer, the tension seat 54 is pressed on the transformer, the clamping cylinder 3 is released, and the spring 52 gradually resets during the cylinder return process, tightening the tension rod 51, and the tension rod 51 tightens the tension sleeve 56, so that the tension sleeve 56 expands and connects tightly with the inner groove of the transformer, playing the role of pre-wiring.

[0051] The expansion state of the tension sleeve 56 means that the flap 562 is flipped outwards of the outer cylinder 563 under the action of the torsion spring 565 .

[0052] After the connection of the pre-wire 6 is completed, the control system instructs each component to reset in order to proceed to the next cycle. The traveling lifting vehicle 7 returns to the initial position to wait for the next current transformer verification task.

[0053] Through the above steps, the current transformer on-site verification auxiliary wiring robot realizes the automatic grasping, positioning and connection of the pre-wired wire 6, greatly improving the efficiency and reliability of on-site verification. The design of the robot fully considers the actual needs of on-site use, and ensures the safety and convenience of operation through precise mechanical structure and intelligent control system.

[0054] This allows the robot to move flexibly on flat ground and reach the predetermined current transformer position without the need for additional transportation. A turret 9 is connected to the upper part of the walking lift 7, and the turret 9 can achieve 360-degree rotation, further enhancing the robot's operating range. A vertical lifting arm 10 is connected to the upper part of the turret 9, and the vertical lifting arm 10 can move up and down to meet the calibration requirements of current transformers at different heights. A lateral extension arm 11 is connected to the top of the vertical lifting arm 10, and the lateral extension arm 11 is responsible for the horizontal extension movement, which expands the robot's operating radius. The end of the lateral extension arm 11 is connected to an equipment installation platform 12, which is used to install the gripper cylinder 3 and other necessary actuators and sensors, ensuring that all operating components can be moved to the desired position with the equipment.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
