Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction, and particularly to a cable bending device for electric power construction. Background Art

[0002] In the power system, as the connecting cable for transmitting and distributing electric energy, it often needs to bend and shape the cable during laying to facilitate the fixing of the cable. For the bending and forming of hard-core cables, the existing bending method is manual bending and forming. Manual bending has the problems of large randomness, inability to guarantee the bending size and shape, and high labor intensity. For large-diameter hard-core cables, bending tools need to be used. By fixing the bending part of the cable and then rotating the cable to make it bend, the operation efficiency is low. For example, a Chinese patent with the authorization publication number CN207533860U discloses an electric wire bender, which includes: a bending disc, a circumferential bending groove matching the electric wire is provided on the outer peripheral surface of the bending disc; a fixing block, a fixing hole matching the electric wire is provided in the fixing block, and the fixing hole is connected and communicated with the bending groove; wherein, the fixing hole is used to fix one end of the electric wire, and the bending groove is used to make the electric wire rotate along its contour under the action of an external force to bend into a set angle, that is, by first fixing the cable and then bending it.

Specific embodiments

[0022] Next, the technical solutions of the present invention will be described in conjunction with the accompanying drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", etc. indicating the orientation or positional relationship, they are only corresponding to the accompanying drawings of the present invention for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation:

[0023] Please refer to Figure 1-6 , the present invention provides a technical solution: a cable bending device for electric power construction, including a base 3. The upper four corners of the base 3 are supported by columns 2 with a workbench 1. There are two support plates 4 on the upper part of the workbench 1. The workbench 1 also has a drive mechanism 5 capable of synchronously driving the two support plates 4 to approach or move away from each other; on the upper part of each support plate 4, there is a positioning wheel assembly 6 and a bending assembly 7 corresponding to it for fixing and bending the cable;

[0024] As Figure 4 , Figure 5 and Figure 6 shown, specifically, the bending assembly 7 includes a vertically arranged sleeve 7.6. A guide plate 7.5 is radially and movably inserted into the barrel of the sleeve 7.6. The guide plate 7.5 can move radially. One end of the guide plate 7.5 is connected by a spring 7.9 with a pressing head 7.8 adapted to the cable; a rotating rod 7.1 is rotationally matched with the upper part of the sleeve 7.6. A connecting plate 7.3 is arranged on the rod body of the rotating rod 7.1 to connect an arc plate 7.4 coaxial with the sleeve 7.6. The other end of the guide plate 7.5 abuts against the inner wall of the arc plate 7.4. An arc block 7.7 is arranged on the inner wall of the arc plate 7.4. A push plate 7.41 is arranged at one end of the arc plate 7.4;

[0025] When the rotating rod 7.1 is rotated, the rotating rod 7.1 drives the arc-shaped plate 7.4 to rotate through the connecting plate 7.3. The guide plate 7.5 abuts against the arc-shaped block 7.7 and pushes the pressing head 7.8 to move to fix the cable. At this time, the push plate 7.41 pushes the cable to bend it; during the rotation of the arc-shaped plate 7.4, the arc-shaped plate 7.4 drives the arc-shaped block 7.7 to rotate. Under the action of the arc-shaped block 7.7, the arc-shaped block 7.7 abuts against the guide plate 7.5 and makes the guide plate 7.5 move radially, so that the guide plate 7.5 pushes the pressing head 7.8 to move. The pressing head 7.8 cooperates with the positioning wheel assembly 6 to fix the cable. At the same time, the push plate 7.41 at one end of the arc-shaped plate 7.4 pushes the cable and bends the cable. By rotating, the cable fixing and bending operations can be achieved simultaneously, which is convenient for operation, time-saving and labor-saving; during the process of pushing the pressing head, a spring 7.9 is provided to increase the redundancy of the radial movement of the guide plate 7.5. That is, when the arc-shaped block 7.7 pushes the guide plate 7.5 to move, the spring 7.9 is in a compressed state. When the pressing head 7.8 tightly presses the cable, the arc-shaped plate 7.4 can still rotate, enabling the push plate 7.41 to have enough moving distance to bend the cable;

[0026] Further, the starting point of the arc-shaped block 7.7 corresponds to the end of the guide plate 7.5. The end point of the arc-shaped block 7.7 is close to the outer wall of the sleeve 7.6. The arc-shaped block 7.7 is concave towards the sleeve 7.6. The inner wall of the arc-shaped block 7.7 is arc-shaped and its axis deviates from the axis of the sleeve 7.6. The outer wall of the arc-shaped block 7.7 is arc-shaped and is fixedly connected to the inner wall of the arc-shaped plate 7.4. The inner wall of the arc-shaped block 7.7 is arc-shaped. When the arc-shaped block 7.7 rotates, it can make the guide plate 7.5 move radially to facilitate fixing the cable;

[0027] Further, the barrel of the sleeve 7.6 is provided with a guide groove 7.61 adapted to the guide plate 7.5, which is convenient for restricting the moving direction of the guide plate 7.5 and can only move radially;

[0028] Further, a positioning plate 7.62 is provided above the guide groove 7.61 inside the sleeve 7.6. The rotating rod 7.1 is inserted into the sleeve 7.6 and its bottom contacts the positioning plate 7.62. A lever 7.2 is also inserted on the upper part of the rod body of the rotating rod 7.1, and the rotating rod 7.1 is rotated by the lever 7.2;

[0029] Further, the driving mechanism 5 includes a bidirectional lead screw 5.3. Both ends of the bidirectional lead screw 5.3 are fixedly connected to the lower part of the workbench 1 through bearing blocks 5.1. Screw nut seats 5.2 are fitted to both reverse-threaded sections of the bidirectional lead screw 5.3. The workbench 1 is provided with a long slot 1.1. The screw nut seats 5.2 are fixedly connected to the support plate 4 through fixing plates. The fixing plates pass through the long slot 1.1. One end of the bidirectional lead screw 5.3 is provided with a rotating rod 5.4. The bidirectional lead screw 5.3 is driven to rotate by the rotating rod 5.4. The two screw nut seats 5.2 on the bidirectional lead screw 5.3 move closer to or away from each other, enabling the distance between the two bending assemblies 7 to be adjustable, which is applicable to two corners with different straight-segment bending requirements.

[0030] Further, the positioning wheel assembly 6 includes a wheel frame 6.1. A roller 6.2 adapted to the cable is installed inside the wheel frame 6.1. The roller 6.2 has an arc-shaped annular groove, which can match the cable well.

[0031] Further, the pressing head 7.8 is a half-roller structure. The pressing head 7.8 has an arc-shaped groove, which can match the cable well.

[0032] Further, one end of the guide plate 7.5 opposite to the arc plate 7.4 is arc-shaped, which can contact the arc block 7.7 well. The arc plates 7.4 of the two bending assemblies 7 are symmetrically arranged.
