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 fixture for transporting lightning arresters of distribution networks. Background Art

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

[0003] The production process of distribution network 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 distribution network 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 clamp for transporting distribution network arresters, so as to solve the problems that the existing distribution network arrester clamps have 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 clamp for handling distribution network lightning arresters includes a servo electric cylinder installed on a machine arm, the output end of the servo electric cylinder is transmission-connected to a clamping jaw assembly, the clamping jaw assembly includes two symmetrically arranged clamping jaw bodies, and an arc groove is provided on the inner side of the clamping jaw body away from one end of the servo electric cylinder.

[0007] Furthermore, the clamping jaw body is transversely provided with a through slot.

[0008] Furthermore, the material of the clamp body is aluminum alloy.

[0009] Furthermore, a plurality of connection holes are provided on the clamp body.

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

[0011] 1. The utility model comprises a servo electric cylinder installed on a robot arm, wherein the output end of the servo electric cylinder is transmission-connected with a clamping jaw assembly, wherein the clamping jaw assembly comprises two symmetrically arranged clamping jaw bodies, wherein an arc groove is provided on the inner side of the clamping jaw body away from one end of the servo electric cylinder.

[0012] Through this setting, the servo electric cylinder controls the opening or closing of the clamp assembly, and the opening and closing dimensions are precisely controlled to ensure reliable grasping of the distribution network arrester; using a robot arm as a clamp carrier, the clamp position can be arbitrarily controlled at multiple angles within a limited space, and an arc groove is opened on the inside of the clamp body to facilitate matching with various distribution network arrester diameters. It automatically centers during grasping, greatly increasing the scope of use of the clamp and effectively solving the problem that the existing distribution network arrester clamp has a small scope of application and the clamp can only clamp products of a single size.

[0013] 2. In the utility model, the clamp body is provided with a through slot in the horizontal direction. With this arrangement, the clamp body is provided with a through slot in the horizontal direction. When grabbing the arrester, the through slot enables the clamp body to pass through the large umbrella skirt of the arrester and clamp the root of the arrester, thereby increasing the clamping area and making the grabbing movement more stable.
