Description

Technical Field

[0001] The utility model belongs to the technical field of lightning arrester fixtures and tools, and in particular relates to a universal transport fixture for lightning arresters of 35kV and above. Background Art

[0002] Lightning arresters are used to protect power lines and electrical equipment in power systems from high transient overvoltages, operating overvoltages, and power frequency transient overvoltages during lightning strikes, and to limit the follow-on time and often the follow-on value. Lightning arresters are sometimes also called overvoltage protectors or overvoltage limiters. Lightning arresters are connected between cables and the earth, usually in parallel with the protected equipment, and can effectively protect electrical equipment. When electrical equipment is operating at normal operating voltage, the lightning arrester will not take effect and will be considered as an open circuit to the ground; when high voltage appears and endangers the insulation of the protected equipment, the lightning arrester will immediately operate to direct the high voltage impact current to the earth, thereby limiting the voltage amplitude and protecting power lines and equipment; when the overvoltage disappears, the lightning arrester quickly returns to its original state, allowing the electrical equipment to operate normally.

[0003] The production process of lightning arresters involves steps such as handling, testing, and packaging. Therefore, robots are widely used in combination with clamps to move lightning arresters. However, due to structural limitations, existing lightning arrester clamps can only clamp products of a single size and have a small scope of application. Utility Model Content

[0004] The utility model aims to provide a universal transport clamp for 35kV and above arresters, so as to solve the problem that the existing arrester transport clamp has a small application range and can only clamp products of a single size.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A universal handling fixture for 35kV and above lightning arresters, comprising a universal connecting plate, a base plate installed on the universal connecting plate, a first forward and reverse screw slide installed on the lower end of the base plate, a first clamping claw fixing seat and a second clamping claw fixing seat installed on the first forward and reverse screw slide, the first clamping claw fixing seat and the second clamping claw fixing seat can slide along the length direction of the first forward and reverse screw slide, and the sliding directions of the first clamping claw fixing seat and the second clamping claw fixing seat are always opposite, a first clamping claw is installed on the first clamping claw fixing seat, a second clamping claw is installed on the second clamping claw fixing seat, the first clamping claw and the second clamping claw are symmetrically arranged, and the first forward and reverse screw slide are located on the base plate. A fixed plate is also installed on the top, and a lifting slide is installed on the fixed plate, and a sliding seat is installed on the lifting slide. The sliding seat can slide along the height direction of the lifting slide, and a second forward and reverse screw slide is installed on the sliding seat, and a third clamping jaw fixing seat and a fourth clamping jaw fixing seat are installed on the second forward and reverse screw slide. The third clamping jaw fixing seat and the fourth clamping jaw fixing seat can slide along the length direction of the second forward and reverse screw slide, and the sliding directions of the third clamping jaw fixing seat and the fourth clamping jaw fixing seat are always opposite, a third clamping jaw is installed on the third clamping jaw fixing seat, and a fourth clamping jaw is installed on the fourth clamping jaw fixing seat, and the third clamping jaw and the fourth clamping jaw are symmetrically arranged.

[0007] Furthermore, a cable drag chain is also arranged beside the lifting slide.

[0008] Furthermore, the first clamping jaw, the second clamping jaw, the third clamping jaw and the fourth clamping jaw are made of aluminum alloy.

[0009] Furthermore, the transmission ends of the first forward and reverse lead screw slide and the second forward and reverse lead screw slide are both transmission-connected to servo motors.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] 1. In the utility model, the first clamping jaw and the second clamping jaw on the first forward and reverse screw slide can move toward or away from each other to realize the opening and closing of the first clamping jaw and the second clamping jaw. Similarly, the third clamping jaw and the fourth clamping jaw on the second forward and reverse screw slide can move toward or away from each other to realize the opening and closing of the third clamping jaw and the fourth clamping jaw. The first clamping jaw and the second clamping jaw clamp the lower end of the arrester, and the third clamping jaw and the fourth clamping jaw clamp the upper end of the arrester to ensure that the arrester is reliably clamped. The first forward and reverse screw slide and the second forward and reverse screw slide are powered by a servo motor, which can accurately control the movement distance of the first clamping jaw fixing seat, the second clamping jaw fixing seat, the third clamping jaw fixing seat, and the fourth clamping jaw, thereby accurately controlling the opening and closing dimensions between the first clamping jaw and the second clamping jaw, and between the third clamping jaw and the fourth clamping jaw to adapt to the clamping of lightning arresters of different sizes. The lifting slide can move the second forward and reverse screw slide up and down to match the clamping position of lightning arresters of different heights, effectively solving the problem that the existing lightning arrester handling fixture has a small application range and can only clamp products of a single size.

[0012] 2. In the utility model, the cable drag chain stores the electrical components and lines to avoid affecting the clamping and handling of the lightning arrester.

[0013] 3. In the utility model, the first jaw, the second jaw, the third jaw and the fourth jaw are made of aluminum alloy, ensuring that no axial or radial movement occurs within the closed size of the first reverse screw slide and the second forward and reverse screw slide, and the high-strength aluminum alloy jaw itself can overcome the bending moment caused by the large-mass lightning arrester.

[0014] 4. In the present invention, by providing a universal connecting plate, it is convenient to install the clamp as a whole on different driving components, thereby increasing the versatility of the clamp. BRIEF DESCRIPTION OF THE DRAWINGS
