[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Power engineering emergency repair refers to the process of emergency maintenance and repair in order to restore power supply as soon as possible and ensure the normal operation of the power system when power supply is interrupted due to power system failure or unexpected circumstances. The power system is composed of transmission lines, substations, distribution equipment, cables, etc. When any part of them fails, it may cause power supply interruption and affect the normal power consumption and production operation of users. Power engineering emergency repair is an indispensable part of power system operation. It can quickly respond to fault events, restore power supply as soon as possible, and ensure the power demand of users and the stable operation of the power system.

[0023] Embodiment 1:

[0024] Based on the technical defects of the existing technology that the cable swings due to strong winds and causes wear on the connection with the fixing device, please refer to Figure 1-Figure 4 The utility model provides a cable fixing frame for emergency repair of power engineering. When the cable swings, the cable drives the clamping plate 44 to slide left and right in the clamping seat 43 to eliminate the wear between the cable and the fixing frame when the cable swings, thereby reducing safety hazards. The utility model has a bracket 1 as a load-bearing carrier, and the bracket 1 is provided with a plurality of mounting plates 2. The mounting plates 2 are provided with mounting bolts 3 and are fixedly connected to the bracket 1 through the mounting bolts 3. A fixing component 4 for fixing the cable and preventing the cable from being worn due to shaking is fixed on the mounting plate 2. An extension component 5 for increasing the number of cable fixations is provided on one side of the bracket 1; when more cables need to be fixed, the extension component 5 can be pulled out of the bracket 1, and then the extra fixing components 4 can be installed on the extension component 5. When installing the cable, the cable is placed between the two clamping seats 43, and the cable can be fixed by the fixing component 4.

[0025] To fix the cable and avoid the problem of abrasion between the cable and the clamp seat 43 when the cable swings, please refer to Figure 2The fixing assembly 4 includes a fixing plate 41 fixedly connected to the mounting plate 2, a lead screw assembly 42 is arranged in the fixing plate 41, two clamping seats 43 symmetrically arranged up and down are connected to the lead screw assembly 42, a slide groove is opened in the clamping seat 43, a clamping plate 44 which can deflect left and right is slidably arranged in the slide groove, and the lead screw assembly 42 is used to drive the two clamping seats 43 to approach each other, so that the cable is clamped between the two clamping plates 44. When the cable swings in the front-back direction, the two ends of the cable will drive the clamping plates 44 to slide in the clamping seat 43, thereby eliminating the wear between the cable and the fixing frame when the cable swings.

[0026] In order to better fix the cable, the clamp seat 43 and the clamp plate 44 are both arc-shaped. This design allows the clamp plate 44 to better fit the cable, thereby achieving a better fixing effect.

[0027] In order to reduce the friction of the splint 44 when sliding, a plurality of ball bearings 45 are provided on the side wall of the splint 44 inside the clamp seat 43, and the splint 44 is rollingly connected to the inner end surface of the clamp seat 43 through the plurality of ball bearings 45. In this way, when the splint 44 slides, rolling is formed with the inside of the clamp seat 43 through the ball bearings 45, resulting in smaller friction and less wear.

[0028] To secure the cables, refer to Figure 2 The screw assembly 42 includes a bidirectional screw 421 rotatably connected to the fixed plate 41, a turning handle is provided at the top of the bidirectional screw 421, and a connecting arm 422 is spirally connected to the outer wall of the bidirectional screw 421 near both ends, and one end of the connecting arm 422 outside the fixed plate 41 is fixedly connected to the clamping seat 43. The turning handle is rotated to drive the bidirectional screw 421 to rotate, and the bidirectional screw 421 drives the two clamping seats 43 to approach each other through the connecting arm 422, so that the clamping plate 44 clamps the cable and fixes it.

[0029] In order to improve the stability of the connecting arm 422 during movement, an inner protrusion 423 is provided on one end of the connecting arm 422 inside the fixed plate 41. The inner protrusion 423 is slidably set in an inner groove opened on the inner wall of the fixed plate 41. The inner protrusion 423 and the inner groove are used to limit the connecting arm 422, ensuring that it is more stable and less likely to shake during movement.

[0030] Embodiment 2:

[0031] When installing cables, different numbers of cables require different types of fixing brackets, which results in poor adaptability of the fixing brackets. To solve this problem, please refer to Figure 3 and Figure 4On the basis of the first embodiment, a guide block 51 is fixed on the inner wall of the bracket 1, and the guide block 51 is slidably set in a guide hole opened on the side wall of the extension plate 52. The extension plate 52 is on the inner side of the bracket 1, and one end of the extension plate 52 is threadedly connected with an adjusting bolt 53. When more cables need to be fixed, the adjusting bolt 53 is loosened, the extension plate 52 is pulled out of the bracket 1, and then the adjusting bolt 53 is re-tightened. The fixing component 4 can also be installed on the extension plate 52, which can increase the number of cables fixed.

[0032] It can be seen from the above embodiments that: when more cables need to be fixed, after loosening the adjusting bolt 53, the extension plate 52 is pulled out of the bracket 1, and then the adjusting bolt 53 is re-tightened. The fixing component 4 can also be installed on the extension plate 52, which can increase the number of cables fixed. When installing the cable, the cable is placed between the two clamping seats 43, the turning handle is turned to drive the bidirectional screw 421 to rotate, and the bidirectional screw 421 drives the two clamping seats 43 to approach each other through the connecting arm 422, so that the clamping plate 44 clamps the cable and fixes it. When the cable swings, the cable drives the clamping plate 44 to slide left and right in the clamping seat 43 to eliminate the wear between the cable and the fixing frame when the cable swings.

[0033] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
