Description

Technical Field

[0001] This invention relates to the field of power engineering technology, and in particular to an auxiliary device for fixing test lines. Background Technology

[0002] In power system field inspections, especially when calibrating high-voltage equipment such as instrument transformers, it is often necessary to reliably connect the step-up equipment to the equipment under test using a high-voltage test line. To ensure operational safety and data accuracy, the test line must remain stable and fixed, meeting specifications such as safe distance to ground. Currently, the industry commonly relies on manual operation methods, such as operators holding insulated operating rods to support the test line, or using simple supports, cable ties, and other temporary means for fixation. These methods are poorly adaptable to the working environment and lack dedicated auxiliary devices, making it difficult to meet the basic requirements of modern power field operations for efficient, safe, and accurate operations.

[0003] However, there is currently no dedicated auxiliary device for fixing the test line in the field inspection of instrument transformers, resulting in several long-standing technical defects: On the one hand, manual hand-held fixing is not only labor-intensive but also has poor support stability, and is prone to test line deviation due to operator fatigue or hand shaking, affecting inspection accuracy and even causing discharge or electric shock risks; on the other hand, the simple bracket structure is inconvenient to fix and adjust, cannot be flexibly adapted to the height and position of the equipment on site, and lacks height adjustment, angle adjustment and visual monitoring functions, resulting in low work efficiency; in addition, the traditional method cannot free up the hands, and it is difficult for operators to simultaneously control the equipment and fix the line, further limiting the safety and reliability of the operation.

[0004] Based on the above problems, we propose an auxiliary device for fixing the test line. Summary of the Invention

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0019] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0020] Reference Figures 1-4This embodiment provides an auxiliary device for fixing test cables, including a clamping assembly 1, comprising a lifting component 11, an adjusting component 12 disposed on the outer wall of the lifting component 11, and a clamping jaw 13 disposed on the outer wall of the adjusting component 12. The clamping jaw 13 is suitable for test cables of different diameters. The clamping jaw 13 can be entirely covered with high-strength engineering plastic or composite insulating material, and has a flexible anti-slip structure (such as silicone pad, toothed texture, etc.) on the inner side of the clamping jaw, which can effectively clamp high-voltage test cables of different outer diameters (Φ8 mm to Φ20 mm) and avoid damage to the cable sheath during clamping. The lifting component 11 is used to drive the entire clamping jaw 13 to move up and down in the vertical direction to meet the requirements of different field equipment installation heights for the safety distance between the test cable and the ground. The adjusting component 12 is fixedly disposed on the outer wall of the lifting component 11, preferably driven by a servo motor, and can controllably rotate the clamping jaw 13 around the horizontal axis to adjust the pitch angle, so that the clamping jaw 13 can adapt to various test cable laying postures such as inclined, horizontal or drooping, and ensure that the clamping surface is always perpendicular to the cable axis.

[0021] In one embodiment provided in this application, the gripper 13 includes a support plate 131. The outer wall of the support plate 131 is movably provided with a first rotating plate 132 and a second rotating plate 133. The inner sides of the first rotating plate 132 and the second rotating plate 133 are provided with teeth 134. The two plates mesh with each other through the teeth 134 to form a symmetrical linkage structure. When one of the rotating plates is driven to rotate around its axis, the other rotating plate rotates synchronously in the opposite direction, thereby realizing the opening and closing action of the gripper 13. Since the first clamping plate 136 and the second clamping plate 137 are linked with the first rotating plate 132 and the second rotating plate 133 through the teeth 134, the two plates always move symmetrically, which can automatically adapt to test lines with different outer diameters, ensure that the clamping center coincides with the cable axis, and avoid eccentric clamping.

[0022] In one embodiment provided in this application, the outer wall of the support plate 131 is also provided with a first servo motor 135. The output end of the first servo motor 135 is connected to either the first rotating plate 132 or the second rotating plate 133. When the first servo motor 135 receives a control signal and drives its output shaft to rotate, it drives the connected rotating plate to rotate. Since the first rotating plate 132 and the second rotating plate 133 mesh with each other through teeth 134, the other rotating plate rotates synchronously in the opposite direction, thereby realizing the symmetrical opening and closing action of the gripper 13.

[0023] In one embodiment provided in this application, a first clamping plate 136 is movably provided on the outer wall of the first rotating plate 132, and a second clamping plate 137 is provided on the outer wall of the second rotating plate 133. The first clamping plate 136 and the second clamping plate 137 are arranged in a mirror symmetrical manner. The inner sides of the first clamping plate 136 and the second clamping plate 137 are covered with a flexible insulating anti-slip layer, forming a surface contact rather than a point contact with the outer surface of the test line, which significantly improves the clamping stability and prevents damage to the cable. The first clamping plate 136 and the second clamping plate 137 move towards the center synchronously during the closing of the clamping claw 13, forming a ring-shaped clamping structure for the high-voltage test line.

[0024] In one embodiment provided in this application, a first connecting rod 138 is movably provided on the outer wall of the first clamping plate 136, and one end of the first connecting rod 138 is movably connected to the support plate 131. A second connecting rod 139 is movably provided on the outer wall of the second clamping plate 137, and one end of the second connecting rod 139 is movably connected to the support plate 131. Through the constraint of the first connecting rod 138 and the second connecting rod 139, the first clamping plate 136 and the second clamping plate 137 can move smoothly along a preset arc during the opening and closing process, avoiding the first clamping plate 136 and the second clamping plate 137 from flipping or getting stuck during the clamping process, and ensuring that the clamping surface is always facing the axial direction of the test line.

[0025] In one embodiment provided in this application, the adjusting member 12 includes a connecting post 121 disposed on the outer wall of the support plate 131, one end of the connecting post 121 being fixedly connected to the support plate 131, and the other end being fixedly connected to the movable frame 122.

[0026] In one embodiment provided in this application, a second servo motor 123 is provided inside the movable frame 122. The output end of the second servo motor 123 is connected to the movable frame 122. The second servo motor 123 drives the movable frame 122 to rotate relative to the lifting member 11 through the output shaft, thereby precisely adjusting the gripping angle of the gripper 13 so that the gripper 13 can adapt to high-voltage test lines with different orientations.

[0027] In one embodiment provided in this application, the lifting component 11 includes a movable rod 111 disposed on the outer wall of the second servo motor 123, a fixed rod 112 sleeved on the outside of the movable rod 111, both the movable rod 111 and the fixed rod 112 are hollow tubes, a drive motor 113 is disposed at the bottom of the fixed rod 112, a lead screw 114 is disposed at the output end of the drive motor 113, a lead screw nut 115 is disposed inside the movable rod 111, the lead screw 114 is disposed inside the fixed rod 112 and is movably engaged with the lead screw nut 115, and the movable rod 111 is driven to rise or fall by the drive motor 113.

[0028] In one embodiment provided in this application, a support frame 116 is provided on the outer wall of the fixed rod 112. The support frame 116 extends outward in a radial or symmetrical structure with the fixed rod 112 as the main vertical load-bearing component, forming a stable bottom support platform. The bottom of the support frame 116 is provided with casters 117. The casters 117 enable the device to be easily pushed and turned in complex work sites such as substations and power distribution rooms, and quickly positioned near different equipment under test. The casters 117 can be equipped with a foot-operated brake mechanism to lock the wheels after the device is in place, ensuring that the overall structure is stationary and stable during operation, and avoiding test line deviation or safety accidents caused by accidental movement.

[0029] In one embodiment provided in this application, a display screen 14 is provided on the outer wall of the support frame 116. The camera 142 transmits the real-time image of the gripper 13 and the test line to the display screen 14. The operator can intuitively observe the clamping position, cable status and surrounding environment on the ground through the screen. The control board 141 is integrated inside the display screen 14 and serves as the main control unit of the whole machine, which coordinates the lifting, clamping, tilting and other actions. The operator can complete the whole process control such as height adjustment, angle adjustment and gripper opening and closing through the touch screen (such integrated intelligent control system is the prior art and will not be described in detail in this application). The top of the movable rod 111 is fixedly provided with a camera 142 and a supplementary light 143. The supplementary light 143 works in conjunction with the camera 142 and is automatically or manually turned on at night, indoors or in a shaded environment to ensure that the image is clearly visible.

[0030] In use, the operator pushes the device to the vicinity of the target equipment at the high-voltage test site. Using the display screen 14, the operator controls the drive motor 113 to rotate the lead screw 114, causing the movable rod 111 to rise and fall along the fixed rod 112, adjusting the gripper 13 to approximately the same height as the test line. Then, using the display screen, the operator controls the second servo motor 123 to drive the movable frame 122 to tilt and rotate, adjusting the gripping angle of the gripper 13 to align it with the test line. Simultaneously, the camera 142 and supplementary light 143 transmit the image of the gripper area back to the display screen in real time for accurate alignment. After confirming the position is correct, the operator activates the first servo motor 135, which, through the meshing of the teeth 134, drives the first rotating plate 132 and the second rotating plate 133 to rotate synchronously in opposite directions, causing the first clamping plate 136 and the second clamping plate 137 to move towards the center, self-centering and clamping high-voltage test lines of different diameters. The entire process requires no manual climbing or hand support, achieving safe, stable, and efficient automated fixing operation.

[0031] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
