A multi-dimensional curved limit device for wire and cable maintenance

Abstract

The invention discloses a multi-dimensional curvilinear limit device for wire and cable maintenance, which comprises a limit base, a twisting curvilinear variable-diameter engagement limit mechanism, a wrap-type expansion and positioning transverse limit device, and a pre-type pull-down cover type protection Mechanism and self-service intermediary PSA limiter. The invention belongs to the field of electric power engineering, and specifically refers to a multi-dimensional curved limit device for wire and cable maintenance; the curved surface principle, dynamic principle and nesting principle are applied to the technical field of electric power engineering, and by changing the spring type dynamic curved The position of the stretching elastic sleeve rod is reduced at the same time, and the circumferential diameter of the spring-type dynamic curved stretching elastic sleeve rod is reduced, so as to realize the axial ring with the support shaft as the central axis in the twisting, curved, diameter-changing and engaging limit mechanism. The wires and cables in different directions on the surface are fixed, and at the same time, the elastic shape of the spring-type dynamic curved stretch elastic sleeve is used to change the tightness of the fixation, which solves the contradictory technical problem that the wires and cables are both fixed and not completely fixed.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering, in particular to a multi-dimensional curved limit device for wire and cable maintenance. Background technique [0002] Wires and cables are used to transmit electrical (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, there are often problems such as weak connections and short circuits due to various factors. Therefore, it is necessary to repair the faulty wire and cable. In order to increase the convenience in the maintenance process, the limit device for wire and cable maintenance is often used to fix the wire and cable to facilitate repairs, but the current limit device for wire and cable maintenance The internal structure is complex, most of them are electric devices, and the manufacturing cost is high. It is impossible to limit the position of a sin...

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
