Description

Technical Field

[0001] This utility model relates to the field of optical cable testing technology, specifically an auxiliary device for multi-turn winding tests of optical cables. Background Technology

[0002] The winding test simulates the deformation process of optical cables in a wound state, detecting their resistance to deformation and physical structural stability to ensure that the optical cable will not suffer internal fiber breakage or signal transmission attenuation due to excessive bending during long-term use. Chinese utility model patent CN222232239U discloses an optical cable winding test machine, including a frame, a servo motor, load weights, and weight clamps. Support frames are respectively provided on the left and right sides of the frame. The load weights are respectively installed at both ends of the optical cable sample via the weight clamps. A transverse roller is rotatably connected between the upper parts of the two support frames. The roller has multiple stepped diameters. A reducer is installed at the output end of the servo motor, and the reducer is installed on the side of one of the support frames. The central shaft at one end of the roller is connected to the reducer. Clamps are installed on the cylindrical surface of each step of the roller. A horizontal limiting mechanism is fixedly installed between the two support frames. The servo motor drives the roller to rotate. The roller has different diameters to meet different testing requirements. The servo motor can precisely control the number of rotations or the angle of the roller. In actual application, it was found that due to height limitations, the number of rotations of the roller 4 was limited (≤2 rotations, which would result in the load touching the ground), making it difficult to meet the actual testing requirements.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for multi-turn winding tests of optical cables, comprising a frame and weights. The frame is a rectangular frame structure welded from rectangular tubular profiles. Two parallel linear guide rails a are fixedly installed on the top of the frame along its length. Two carrier plates a are slidably connected between the two linear guide rails a. Two parallel linear guide rails b are fixedly installed on each carrier plate a. The linear guide rails b are perpendicular to the linear guide rails a and are not in the same plane. Carrier plates b are slidably connected on the linear guide rails b. A vertical plate is fixedly installed in the middle of the carrier plate b. Two first guide wheels distributed vertically are installed on one side of the vertical plate. A second guide wheel is installed on the upper side of the carrier plate a via a bracket. A pull ring is fixedly installed at the rear of the vertical plate. The pull ring is connected to a steel wire rope, and the other end of the steel wire rope passes around the second guide wheel and connects to the weights.

[0005] Preferably, a guide rail clamp is installed at the bottom of the carrier plate a, the guide rail clamp being used to lock the carrier plate a on the linear guide rail a.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Please see Figure 1-4 This utility model provides a technical solution: an auxiliary device for multi-turn winding test of optical cable, including frame 1 and weights 9. Frame 1 is a rectangular frame structure welded from rectangular tube profiles. Two parallel linear guide rails a2 are fixedly installed on the top of frame 1 along the length direction. Two carrier plates a3 are slidably connected between the two linear guide rails a2. A guide rail clamp 10 (a commercially available mature product) is installed at the bottom of the carrier plate a3. The guide rail clamp 10 is used to lock the carrier plate a3 on the linear guide rails a2.

[0015] Each carrier plate a3 is fixedly mounted with two parallel linear guide rails b7, which are perpendicular to linear guide rail a2. A carrier plate b5 is slidably connected to the linear guide rail b7. A vertical plate 6 is fixedly mounted in the middle of the carrier plate b5. Two first guide wheels 8, distributed vertically, are mounted on one side of the vertical plate 6. During the test, the two ends of the traction rope are connected to the two ends of the test optical cable to form a loop. The first guide wheels 8 guide the traction rope. A second guide wheel 4 is mounted on the upper side of the carrier plate a3 via a bracket. A pull ring is fixedly mounted at the rear of the vertical plate 6. The pull ring is connected to a steel wire rope, and the other end of the steel wire rope passes around the second guide wheel 4 and is connected to a weight 9. The first guide wheels 8 and the second guide wheels 4 have the same diameter and have annular grooves on their outer sides. The annular grooves serve to restrain and prevent the wire from jumping.

[0016] Working principle: such as Figure 4 As shown, during use, the optical cable to be tested is wound onto the drum of the testing machine. Both ends of the cable are connected to the ends of a traction rope via clamps, forming a closed loop. The loop passes through the first guide wheel 8 and is taut between the winding testing machine and this auxiliary equipment (the weight 9 applies a backward pulling force to the upright plate 6 via a steel wire rope, thus tauting the optical cable to bear the lateral load). The drum of the testing machine rotates clockwise n times, then counterclockwise n times, repeating this process to achieve the winding test. This auxiliary equipment changes the load of the optical cable to be tested from vertical to horizontal, is not limited by height, and allows for more turns.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
