As shown in fig. 1 to 4, a cable bending apparatus in an embodiment includes a telescopic assembly 10 and an auxiliary support assembly 20. The telescopic assembly 10 has at least one end provided with a first arc-shaped plate 11 adapted to the cable. The auxiliary support assembly 20 is adapted to the telescoping assembly 10 to provide a fulcrum for the telescoping assembly 10.
The technical scheme of application embodiment one, flexible subassembly 10 and auxiliary stay subassembly 20's cooperation can be taken the cable curved through the flexible of flexible subassembly 10, and auxiliary stay subassembly 20's effect just provides the fulcrum for flexible subassembly 10, and the operation of taking the curve can be carried out to the cable to the setting of cooperation first arc 11 reliable and stable. The technical scheme of the first embodiment effectively solves the problem that the adjustable range is relatively limited when the traditional cable straightener in the prior art is used for bending the cable.
As shown in fig. 1 to 4, in the first embodiment, the first arc plate 11 is rotatably connected to the telescopic assembly 10 through the ear plate. The structure can ensure that the first arc-shaped plate 11 is rotatably connected with the telescopic assembly 10 and has higher stability. Specifically, the two ear plates are arranged at intervals and are rotatably connected with the telescopic assembly 10 through a rotating shaft.
As shown in fig. 1 to 4, in the first embodiment, the auxiliary support assembly 20 includes a support body 21 and a support structure 22. The supporting structure 22 is fixed on the supporting body 21, and when the telescopic assembly 10 extends, one end of the telescopic assembly 10 far away from the first arc-shaped plate 11 tightly props up the supporting structure 22. The above structure can cooperate with the telescopic assembly 10 to form an effective support, thereby ensuring the smooth operation of bending.
As shown in fig. 1 to 4, in the first embodiment, the supporting body 21 is made of "U" shaped steel, the supporting body 21 has a "U" shaped groove, and the supporting structure 22 is made of a bearing plate fixed on the supporting body 21. The structure can enable the supporting main body 21 to have higher strength, and the arrangement of the bearing plate ensures the stability of the support of the telescopic assembly 10. Further, a reinforcing plate 211 is arranged on the U-shaped groove to increase the strength of the supporting body 21 and improve the strength and stability of the cable bending device.
As shown in fig. 1 to 4, in the first embodiment, the receiving plate is mounted on a side of the support body 21 away from the "U" shaped groove, and the receiving plate has an "L" shaped structure and includes a fixing portion fixed to the support body 21 and a receiving portion extending in a direction away from the support body 21. The bearing plate with the L-shaped structure can have a larger fixing area with the support main body 21 so as to ensure the stability of the bearing plate, and the bearing plate and the support main body 21 have better connection strength.
As shown in fig. 1 to 4, in the first technical solution of the embodiment, a reinforcing structure 12 is disposed at an end of the telescopic assembly 10 away from the first arc-shaped plate 11, and when the cable bending apparatus is used, the reinforcing structure 12 abuts against the auxiliary support assembly 20. The reinforcing structure 12 in the above structure can prevent the main structure of the telescopic assembly 10 from being damaged, thereby preventing the telescopic assembly 10 from being worn and prolonging the service life of the telescopic assembly 10.
As shown in fig. 1 to 4, in the first embodiment, the telescopic assembly 10 is configured as a hydraulic rod. The hydraulic rod can have stronger and more stable telescopic force. Other telescopic structures can also be arranged according to the needs, such as: a threaded rod structure or a cylinder structure.
Moreover traditional cable straightener is inconvenient to carry, and the weight and the volume of traditional equipment are all great, need two people at least to carry in the ditch. Since the cable bending work needs to be carried out in a tunnel in a pushing mode, the weight and volume burden is further enlarged. And traditional cable straightener is fragile, proves through field practice that the straightener can not obtain good bending effect to the cable of cross-section more than 1600mm 2. When the cable cross-section is too big, cause easily to take the damage of curved equipment, increased construction cost and activity duration. Meanwhile, the traditional cable straightener occupies a large space, the traditional bending equipment needs to enable a cable to pass through the traditional straightening equipment, so that a larger space is occupied, and the space is limited before each single-core cable is bent, so that the occupied larger space can cause interference to construction.
The cable bending device of the second embodiment is different from the first embodiment in that:
as shown in fig. 1 to 4, in the second embodiment, the receiving plate is installed in the U-shaped groove, and a limiting portion is disposed on a side of the receiving plate away from the U-shaped groove. The board of accepting of above-mentioned structure can cooperate with flexible subassembly 10 better, and the setting of spacing portion can avoid flexible subassembly 10 accident to deviate from simultaneously and accept the board, and then guarantees that flexible subassembly 10 is taking reliable and stable in the curved operation.

The auxiliary supporting component 20 in the above structure can be matched with a cable, and then one end of the telescopic component 10 far away from the clamping groove is used as a fulcrum.
As shown in fig. 1 to 4, in the second technical solution of the embodiment, a second arc-shaped plate 231 is arranged in the clamping groove, and the second arc-shaped plate 231 is adapted to the cable. The setting of second arc 231 in above-mentioned structure can cooperate with the cable better, reduces to take the wearing and tearing of curved in-process.
From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects: the cooperation of flexible subassembly 10 and auxiliary stay subassembly 20 can be taken the cable through the flexible of flexible subassembly 10 and bend, and auxiliary stay subassembly 20's effect just provides the fulcrum for flexible subassembly 10, and the operation of taking the bend can be taken to the cable to the setting up of cooperation first arc 11 reliable and stable. The technical scheme of the invention effectively solves the problem that the adjustable range of the traditional cable straightener in the prior art is relatively limited when the traditional cable straightener is used for bending the cable.
