Description

Technical Field

[0001] The utility model relates to the technical field of wiring auxiliary devices, in particular to a wiring auxiliary device based on a magnetic jack. Background Art

[0002] During the installation and maintenance of large hydroelectric generator sets, wire ropes, nylon ropes, brown ropes and other ropes are used as materials to play the role of binding, fixing, guiding, and safety protection in on-site work. In the safety protection of large-sized components, it is often necessary to arrange ropes horizontally and tighten them; but due to the long total length of the rope and the heavy weight in the middle, the rope cannot be effectively fixed and falls, and the friction resistance is large and it cannot be effectively tightened. Taking the fixed guide vane safety protection device as an example, it is usually installed in the horizontal direction of the fixed guide vane circumference, and then the safety net is installed on the rope. The rope often lacks effective guiding and limiting devices and cannot be effectively tightened, and cannot form a strong and safe protection. Utility Model Content

[0016] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0017] See attached Figure 1-5 In order to realize the above technical features, the purpose of the utility model is achieved as follows:

[0018] A routing auxiliary device based on a magnetic jack includes a magnetic jack 1, wherein the magnetic jack 1 is rotatably connected to a limiting bracket 3 through a connecting seat 2, and a limiting portion 3a is provided on the limiting bracket 3; the limiting portion 3a is sleeved on the outer side of a rope 4, and is used to support and limit the rope 4. Through the setting of the magnetic jack 1, the device of the present application can be installed on the surface of a part made of ferromagnetic material. When the device of the present application is applied to the installation of the rope in the horizontal direction, the rope 4 passes through the limiting portion 3a on the limiting bracket 3, and the limiting portion 3a supports and limits the middle section of the rope 4 to bear the weight of the middle section of the rope 4, thereby preventing the middle section of the rope 4 from falling under the action of gravity; when the device of the present application is applied to the installation of the rope in the non-horizontal direction, the rope 4 passes through the limiting portion 3a on the limiting bracket 3, and the limiting portion 3a limits the middle section of the rope 4, so as to achieve the setting of the predetermined position of the rope.

[0019] For further information, see Figure 2 The limiting bracket 3 is provided with an opening 3b and a rotating shaft 3c. The two rotating shafts 3c are distributed parallel to each other and pass through the opening 3b. The axis of the rotating shaft 3c is perpendicular to the extension direction of the opening 3b. The gap between the two rotating shafts 3c constitutes the limiting portion 3a. When the rope 4 passes through the two rotating shafts 3c, rolling friction is formed with the surface of the rotating shaft 3c to reduce the friction resistance during the relative displacement between the rope 4 and the rotating shaft 3c. At the same time, the rotating shaft 3c guides and limits the rope 4.

[0020] Furthermore, a guide wheel 3d is installed on the rotating shaft 3c, and a groove 3d1 adapted to the rope 4 is provided on the guide wheel 3d. Through the setting of the guide wheel 3d and the groove 3d1, the friction surface between the rope 4 and the guide wheel 3d is increased on the one hand, and a better guiding effect is achieved at the same time.

[0021] The following will take the application of the device of the present application for the installation of the safety net on the fixed guide vane as an example for further explanation:

[0022] See also Figure 3-5 When in use, a pair of devices of the present application are sequentially arranged at a preset distance on multiple fixed guide vanes 8, and a pair of devices of the present application are arranged up and down; two upper and lower ropes 4 are prepared, and each rope 4 is used as a safety main rope to pass between two guide wheels 3d of multiple groups of devices of the present application at the same height. The safety net 5 is fastened to the rope 4 by buckles 6, and two rope heads are set at both ends of each rope 4, and the tightening device 7 is connected to the rope heads at both ends of the rope 4. When the tightening device 7 is tightened, the rope 4 is tightened, thereby realizing the installation of the rope 4 and the installation net 5.
