Problems solved by technology

However, the performance of this kind of line stretching device with a spring as a single potential energy element tends to decline over time, especially under harsh environmental conditions in the field. The performance and parameters of the potential energy element will change (such as yield, creep, slip); secondly, the load of the flexible part will also change under the influence of the natural environment, such as ice and snow in winter will cause the load of the wire to change. If the pre-tension or constant tension cannot be adjusted in time, it will affect the use effect or affect the work

Embodiment Construction

[0019] The structure and working principle of the embodiments of the automatic tension compensator for flexible parts will be described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 , in the automatic tension compensator for flexible parts, the motor 1 is provided with a controller 13, the screw rod 7 is connected with the motor 1 and the reducer 2, and is rotatable. Connection, the screw rod 3 between the U-shaped nut 5 and the reducer 2 is sleeved with a pressure sensor 3 and a spring 4; the three-dimensional structure of the U-shaped nut 5 (see figure 2 ), its outside is provided with convex rail 5-2, is fixed with insulating bar 9 between the two fork bars of U-shaped nut 5, is used for hanging cable 10 (being flexible part). U-shaped nut 5 is positioned in sleeve pipe 6, and its protruding rail 5-2 cooperates with the recessed rail of sleeve pipe 6 inboards (see image 3 ), the two form a concave-convex track, so that the U-shaped nut 5...

Abstract

The invention relates to an automatic tensile-force compensator of a soft part, which comprises an electric motor, a speed reducer, an axial positioning screw rod, a nut, a fixed sleeve and an infrared switch, wherein the electric motor is provided with a controller, the screw rod and the central thread hole of the nut form a spiral pair, the nut is provided with a connection member of a soft part and positioned in the fixed sleeve, the nut and the fixed sleeve are used cooperatively by tracks of mutual concave and convex close fit, and the nut slides along a fixed track. The invention changes the work mode of the passive adaptability compensation of the traditional potential-energy element compensator, and can timely and actively control the load change according to the using requirements.

Description

technical field [0001] The invention relates to an automatic tension compensator for flexible parts, in particular to a tension compensator for keeping flexible wires such as cables and cables erected with a large span in a tensioned state, and is especially suitable for the field of power transmission and transformation in rail transit systems. Background technique [0002] Flexible parts mainly refer to wires such as cables or ropes made of various materials. They are often used in various occasions such as transmission lines or cables. The main difference between them and rigid parts is that they can only transmit pulling force, not thrust. For flexible parts such as cables erected in the field with a large span, in order to ensure that the flexible parts are in a tensioned state, it is necessary to connect pretension potential energy elements at both ends of the span of the flexible parts to prevent bending and relaxation of the flexible parts due to their own gravity. ...
