The curved surface principle, the dynamic principle and the nesting principle are applied to the technical field of electric power engineering, and the circumferential diameter of the spring type dynamic curved stretching elastic sleeve rod is reduced while the position of the spring type dynamic curved stretching elastic sleeve rod is changed. According to the invention, the elastic shape of the spring-type dynamic curved stretching elastic sleeve rod is utilized to fix wires and cables in different directions on the axial annular surface taking the supporting shaft as the central shaft in the twisting curved variable-diameter clamping limiting mechanism, and meanwhile, the elastic shape of the spring-type dynamic curved stretching elastic sleeve rod is utilized to change the fixing tightness, so that the technical problem that the wires and cables are fixed but not completely fixed is solved.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering, and specifically refers to a multi-dimensional curving limiting device for wire and cable maintenance. Background technique [0002] Wires and cables are used to transmit electric (magnetic) energy, information, and wire products that realize electromagnetic energy conversion. They are widely used in power engineering. During the use of wires and cables, problems such as weak connections and short circuits often occur due to various factors. Therefore, it is necessary to repair the wires and cables that have problems. In order to increase the convenience of the maintenance process, the wire and cable maintenance limit device is often used to fix the wires and cables for easy repair. However, the current wire and cable maintenance limit device is mainly The internal structure is complex, most of which are electrical devices, and its manufacturing cost is relatively high. It is i...

Problems solved by technology

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a multi-dimensional curved limit device for wire and cable maintenance, aiming at the need to fix the wire and cable in the process of fixing the wire and cable (to facilitate the maintenance process) The contradictory technical problem of limiting the position of the wires and cables for easy maintenance) and the inability to completely fix the wires and cables (it is convenient to adjust the fixing position of the wires and cables after the wires and cables are fixed are not disassembled). The principle, dynamic principle and nesting principle are applied to the field of electric power engineering technology, using the characteristics of the threaded object to rotate and move during the rotation process, on the one hand, with spring-type dynamic curved stretching, elastic sleeve rod coiled stretching Movement, by changing the position of the spring-type dynamic curved stretching elastic sleeve rod during the stretching process and reducing the circumferential diameter of the spring-type dynamic curved stretching elastic sleeve rod, to achieve the engagement of twisting and bending diameter reduction The process of fixing wires and cables in different directions on the axial annular surface with the support shaft as the central axis in the limit mechanism, on the other hand, provides power for the positioning of the expansion-type interspersed wrapping pressure plate in the wrap-type expansion positioning lateral limit device, and at the same time By rotating the screw thread to connect the object, using the elastic shape of the spring-type dynamic curved elastic sleeve rod to change the firmness of the fixation, it is convenient to pull and adjust the fixed position of the wire and cable, which effectively solves the problem that the wire and cable are both fixed and cannot be completely fixed. Contradictory technical problems, eliminating the need for maintenance workers to repeatedly dismantle and fix the process, effectively improving the maintenance efficiency
