Description

Technical Field

[0001] This utility model relates to the field of cable straightener technology, specifically to an intelligent cable straightener. Background Technology

[0002] Currently, during the secondary wiring construction of substations, the existing method for straightening control cable cores involves a cable core straightener. This straightener includes a base plate, a working seat, a drive mechanism, and a movable clamping mechanism on the working seat. The movable clamping mechanism is used to fix the ends of the cable cores, and the drive mechanism is used to drive the movable clamping mechanism to move on the working seat. The straightening of the control cable cores is achieved through the drive mechanism and the movable clamping mechanism. However, this method makes it difficult to control and quantify the force applied to the straightening of the control cable cores. If the force is too small, the control cable cores will not be straightened; if the force is too large, the control cable cores may break. Therefore, experienced personnel are required to operate it.

Detailed Implementation

[0017] The technical solution of one embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0018] Please see Figure 1-3 :

[0019] An intelligent cable straightener includes a frame 1, a moving block 2, a moving block drive device, a cable tension measuring device, a controller 6, and a touch screen 61. The moving block 2 is equipped with a second cover 22. The moving block 2 is connected to both the moving block drive device and the cable tension measuring device. The moving block drive device drives the moving block 2 to move back and forth. The cable tension measuring device clamps the cable and measures its tension. The controller 6 is electrically connected to the moving block drive device and the cable tension measuring device, and controls the moving block drive device to straighten the cable at a set pressure value. This invention performs cable straightening operations by setting a preset pressure value on the controller 6 before straightening. This allows the straightener to straighten the cable with a constant tension, ensuring the straightening effect and improving work efficiency.

[0020] To enable the pressure sensor to measure the cable tension in real time, the cable tension measuring device includes two fixed blocks 51 arranged parallel to each other. The fixed blocks 51 are perpendicular to the moving block 2 of the moving drive device. A guide rod 52 is provided between the two fixed blocks 51. Two sliders 53 are slidably fitted on the guide rod 52. A pressure sensor 54 is provided between the two sliders 53. A cable clamping block 55 is vertically provided on the front slider 53. The cable clamping block 55 has a screw hole, and a clamping bolt 56 is screwed into the screw hole. The cable is clamped between the cable clamping block 55 and the nut of the clamping bolt 56.

[0021] For the convenience of clamping and fixing the cable, the clamping bolt 56 includes a screw rod main body 561 and a nut 562. The front end of the nut is provided with an annular clamping surface. The annular clamping surface should be set as large as possible to enhance the clamping effect on the cable and avoid damage to the cable surface.

[0022] The moving block driving device includes a fixed disk 31, a driving motor 32, a lead screw 33, a coupling, and a moving nut 34. The fixed disk 31 is a square - like groove body with an upward opening. On both sides of its upper opening, there are vertical extension edges for installing the second cover body 22. The rear end of the fixed disk 31 is connected to the driving motor 32. The lead screw 33 is arranged inside the fixed disk 31. The lead screw 33 is connected to the rotating shaft of the driving motor 32 through a coupling. A moving nut 34 is sleeved on the lead screw 33. The moving nut 34 is fixedly connected to the moving block 2. The rotation of the lead screw 33 can drive the movement of the moving block 2 through the moving nut 34. The fixed disk 31 is arranged on the top plate 11 of the frame 1.

[0023] The fixed disk 31 is provided with a first cover body 36. In order to enable the first cover body 36 to cover the fixed disk 31 without affecting the movement of the moving block 2, the moving block 2 is in a shape similar to a "Ji" character. On both sides of it, there are symmetrically arranged outward bending installation grooves 21 (this shape is different from the "Ji" character, so it is said that the moving block 2 is in a shape similar to a "Ji" character). The first cover body 36 is in a Π shape and is installed in the bending installation groove 21.

[0024] During the operation of the straightener, since the cable is often in different positions, it is necessary to change the direction of the straightener. However, to avoid changing the direction of the entire straightener, the method of rotating the fixed disk 31 can be adopted to replace changing the direction of the entire straightener to improve the operation efficiency. The front end of the fixed disk 31 is provided with a front connecting ear 311. The front connecting ear 311 is rotationally connected to the top plate 11 of the frame 1 through a rotating shaft. The rear end of the fixed disk 31 is provided with a rear connecting ear 312. The rear connecting ear 312 is provided with a first arc - shaped groove. The front end of the top plate 11 is provided with an outward extending part 111. The extending part 111 is provided with a second arc - shaped groove 1111 corresponding to the first arc - shaped groove. Below the extending part 111, there is also an arc - shaped support plate 313. The arc - shaped support plate 313 is in an inverted 7 - shape and is connected to the upper part of the rear side of the frame 1. The arc - shaped support plate 313 is provided with a third arc - shaped groove (not drawn) corresponding to the second arc - shaped groove 1111. The rear connecting ear 312 is connected to the first arc - shaped groove (not drawn), the second arc - shaped groove 1111, and the third arc - shaped groove through an adjusting bolt 314.

[0025] To prevent the cable from being pulled apart due to excessive travel of the moving block 2 of the straightener, the travel of the moving block 2 needs to be limited. The straightener also includes a limiting mechanism for the moving block 2, which includes a limiting groove 12, a bumper 121, and a limiting block 122. The limiting groove 12 is provided on one outer side of the fixed plate 31 along the length direction. Bumpers 121 are provided on both sides of the limiting groove 12. The moving block 2 is connected to the limiting block 122. The limiting block 122 moves with the moving block 2 and is positioned between the two bumpers 121.

[0026] Working principle:

[0027] First, set the preset tension value of the cable and the travel of the moving block through the touch screen. Then, control the moving block to move to the rear end through the controller (which uses existing technology and can also use existing technology to set the remote control). Loosen the clamping bolt, place the cable between the clamping surface of the nut and the cable clamping block, tighten the clamping bolt to fix the cable, and start the drive motor again to straighten the cable.

[0028] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
