Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to an automated device for calibrating and locking surge arrester nuts. Background Technology

[0002] A surge arrester is an overvoltage protection device connected in parallel with the protected equipment between a power transmission line and the ground. It is primarily used to limit lightning overvoltages and switching overvoltages, protecting electrical equipment such as power transformers, switchgear, and distribution lines from damage caused by transient overvoltages. The surge arrester is equipped with a conductive rod and fasteners (usually a combination of bolts and nuts). Tightening the nuts secures the surge arrester to the steel crossarm of the pole or a mounting bracket, while simultaneously fixing the high-voltage leads of the protected system to the upper end of the surge arrester.

[0003] Surge arresters come in a wide variety of specifications, with significant differences in structural dimensions and installation methods across different voltage levels, series, and applications. In the assembly and tightening process of surge arresters, the assembly and tightening of the nuts is a critical step, directly affecting the electrical connection reliability, sealing performance, and long-term operational safety and stability. However, existing surge arrester nut assembly methods generally suffer from the following drawbacks: Nut assembly lacks versatility, as a single type of equipment cannot handle the assembly of nuts for multiple surge arrester models; manual or semi-automatic assembly is inefficient, requiring manual handling of a series of actions such as material handling, positioning, tightening, and unloading for each tightening operation, resulting in a slow cycle time and severely limiting the output capacity of the entire production line; and the consistency of tightening quality is difficult to guarantee, easily leading to insufficient tightening torque or over-tightening of the nuts. During long-term operation, these nuts may loosen and fall off due to vibration, causing surge arrester malfunction. Furthermore, when a large torque is applied to the surge arrester during tightening, it may cause electrode rotation or seal damage, similarly affecting equipment reliability.

[0004] In view of this, there is an urgent need to design an automated device for calibrating and locking the nuts of surge arresters in order to solve the technical defects in the self-assembly of the nuts of surge arresters. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an automated device for calibrating and locking surge arrester nuts, comprising a frame on which a translation component and a working platform driven by the translation component are mounted. The working platform is equipped with a surge arrester bearing station and an attitude adjustment component. The attitude adjustment component faces the surge arrester bearing station and is used to adjust the surge arrester at the bearing station to a preparatory posture. Along the translation direction of the working platform, a visual inspection component and a nut calibration and locking component are sequentially arranged on the side of the working platform. The visual inspection component detects the nut position of the surge arrester at the bearing station, and the nut calibration and locking component adjusts its position according to the nut position and performs a locking action on the surge arrester nut.

[0006] The present invention is further configured such that the nut calibration and locking assembly includes a component base plate, a vertical calibration power source connected to the component base plate, a vertical calibration plate driven by the vertical calibration power source, a horizontal calibration power source connected to the vertical calibration plate, a horizontal calibration plate driven by the horizontal calibration power source, a vertical calibration power source connected to the horizontal calibration plate, a vertical calibration plate driven by the vertical calibration power source, a nut locking power source connected to the vertical calibration plate, and a nut locking bit driven by the nut locking power source.

[0007] The present invention is further configured such that the component substrate is fixed on the equipment frame, and a vertical guide rod is provided at the lower end of the vertical calibration plate, the vertical guide rod being movably connected to the component substrate.

[0008] The present invention is further configured such that a calibration screw mechanism is provided at the upper end of the vertical calibration plate. The calibration screw mechanism includes a calibration screw fixing seat, a calibration screw body connected to the calibration screw fixing seat, and a calibration screw nut movably connected to the calibration screw body. The output end of the horizontal calibration power source is linked to the calibration screw body through a coupling. The horizontal calibration plate is connected to the calibration screw nut.

[0009] The present invention is further configured such that the visual inspection component includes a visual inspection bracket connected to the equipment frame, a visual inspection camera connected to the visual inspection bracket, and an annular light source connected to the visual inspection bracket, wherein the annular light source is located between the visual inspection camera and the surge arrester bearing position.

[0010] The present invention is further configured such that the attitude adjustment component includes an attitude adjustment power source and an attitude adjustment plate driven by the attitude adjustment power source, and an attitude adjustment top block is connected to the attitude adjustment plate, the attitude adjustment top block being detachably connected to the attitude adjustment plate.

[0011] The present invention is further provided with a surge arrester pressing assembly above the working platform, the surge arrester pressing assembly including a pressing power source and a pressing element driven by the pressing power source.

[0012] The present invention is further configured such that the translation component includes a translational power source, a translational lead screw fixing seat connected to the equipment frame, a translational lead screw body connected to the translational lead screw fixing seat, a translational lead screw nut movably connected to the translational lead screw body, and a translational guide rail located on the equipment frame. The working platform is connected to the translational lead screw nut, and the working platform is connected to the translational guide rail via a slider.

[0013] The present invention is further configured such that arrester positioning blocks are provided around the arrester bearing position.

[0014] The present invention is further configured such that the visual inspection component and the nut calibration and locking component are provided on both sides of the working platform.

[0015] The working principle of this automated equipment for calibrating and locking surge arrester nuts is as follows: The surge arrester is placed on the surge arrester support station. The equipment's start switch is pressed. The attitude adjustment component adjusts the surge arrester to a preparatory position. Then, the translation component drives the work platform to move the surge arrester to the detection position corresponding to the vision inspection component. The vision inspection component performs point detection on the nut on the surge arrester to obtain the nut point detection result. The translation component then drives the work platform to move the surge arrester to the locking position corresponding to the nut calibration and locking component. The nut calibration and locking component adjusts the nut bit position according to the nut point detection result. After adjustment, the nut of the surge arrester is locked. After locking, the attitude adjustment component resets, and the surge arrester can be removed from the surge arrester support station.

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] This technical solution utilizes an automated device for calibrating and locking surge arrester nuts. Through a visual inspection component, it can automatically identify the specific location of the nuts on different surge arresters. Combined with the adaptive position adjustment of the nut calibration and locking component, the device can adapt to surge arresters of various specifications, series, and applications without replacing or adjusting the hardware. This solves the problem of the lack of versatility in existing equipment, achieving highly flexible production that allows a single device to be compatible with the nut locking of multiple surge arrester models. It also ensures the accuracy and repeatability of the locking action, avoiding deviations caused by manual visual alignment.

[0018] This technical solution integrates a translation component, an attitude adjustment component, a visual inspection component, and a nut calibration and locking component, realizing fully automated operation of the surge arrester from attitude adjustment and nut positioning to automatic locking. The entire process eliminates the need for repetitive manual operations such as material handling, positioning, tightening, and unloading, thus eliminating the bottleneck of manual or semi-automatic operation, significantly accelerating the cycle time of a single locking operation, greatly improving the efficiency of nut locking, and effectively preventing damage such as surge arrester electrode rotation and sealing structure destruction caused by excessive torque during tightening, while also ensuring the consistency of nut locking quality.
