Description

Technical Field

[0001] The utility model relates to the technical field of cable bending machines, in particular to a bending machine used for cable testing. Background Art

[0002] At present, in the construction of power cables, in order to achieve effective connection with power supply and use equipment such as overhead lines, switch cabinets and metering facilities, it is necessary to use external force to bend the power cable into a certain arc so that the direction of the power cable can be effectively changed. This is called power cable bending. With the acceleration of the industrialization of small towns and the continuous advancement of the electrification construction of new rural areas, power supply companies and power customers have higher and higher standards for the design, construction and maintenance of power facilities, and the awareness of safe power supply and use has gradually increased. The use of power cables has gradually become popular. With the gradual increase in the power load of power customers, and the safety, reliability and practicality of power cables have been gradually recognized by customers, the use of power cables with larger cross-sections has increased dramatically. In the construction and maintenance of cables, due to factors such as process requirements or restrictions on special construction sites, it is often necessary to use external force to bend the cable to change the path to meet the installation requirements, which increases the workload of the staff on bending the power cables.

[0003] In traditional power cable bending, the bending trough plate on the bending machine is fixed and has a fixed distance from the fixed wheel, which makes it impossible to bend cables of different diameters. In addition, the bending trough plate cannot automatically return to its initial position after bending, resulting in the bending trough plate often being unable to return to its initial position parallel to the fixed wheel. This creates certain obstacles for the cable to enter between the fixed wheel and the bending trough plate, and may even block the entry of the cable. Utility Model Content

[0004] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures specifically pointed out in the description and other drawings of the description.

[0005] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a bending machine for cable testing.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is: a bending machine for cable testing, comprising: a base, a rotating rod installed on the base, a fixed wheel arranged on the rotating rod, a plug plate connected to the fixed wheel, a slot seat plugged with the plug plate and fixed on the base, a rotating frame, a bending slot plate, an adjusting frame, a sleeve, a screw, and a hand wheel. The two sides of the rotating frame are rotatably arranged on the upper and lower sides of the rotating rod, the fixed wheel is located between the two sides of the rotating frame, a bending slot plate is arranged on the side of the fixed wheel and is installed on the adjusting frame, the adjusting frame is connected to the sleeve, one side of the screw is threadedly connected to the rotating frame and inserted into the sleeve, and the other side is connected to the hand wheel; wherein a slide groove is opened on the base, a traction rod and two springs are embedded in the slide groove, springs are connected to both sides of the traction rod, and the upper end of the traction rod passes through the slide groove and is connected to the rotating frame.

[0007] Preferably, the traction rod is located centrally between the two springs.

[0008] Preferably, the traction rod and the slide groove are clearance-matched.

[0009] Preferably, the slide groove and the rotating rod are located at the same axis.

[0010] Preferably, at least four anti-movement foot assemblies are installed on the lower side of the base.

[0011] Preferably, the anti-movement foot assemblies are located at the lower sides of the four corners of the base.

[0012] Preferably, the anti-movement support foot assembly includes a stabilizing block, a vertical rod, and a triangular support. One side of the vertical rod is connected to the stabilizing block and the other side is connected to the triangular support. The triangular support is provided with three curved edges, which support the ground at equal angles.

[0013] Preferably, the stabilizing block is connected to the underside of the base.

[0014] By adopting the above technical scheme, the beneficial effect of the utility model is as follows: the utility model rotates the screw rod through the hand wheel, so that the screw rod pushes the sleeve to rotate into the rotating frame, causing the adjustment frame to push the bending slot plate to rotate until the bending slot plate is close to the cable, and this process can flexibly adjust the distance between the bending slot plate and the fixed wheel, so that cables of different diameters can be bent, with stronger adaptability and lower limitations, and after bending and pulling out the cable, the rotating frame will return to the initial position under the action of the spring to restore its original state, so that the bending slot plate also returns to the initial position, and returns to the initial position parallel to the fixed wheel, thereby effectively preventing the entry of the cable from being stuck, flexible operation, and reduced failure rate.

[0015] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.

The two sides of the rotating frame 6 are rotatably arranged on the upper and lower sides of the rotating rod 2, the fixed wheel 3 is located between the two sides of the rotating frame 6, a bending slot plate 7 is arranged on the side of the fixed wheel 3 and is installed on the adjusting frame 8, the adjusting frame 8 is connected to the sleeve 9, one side of the screw 10 is threadedly connected with the rotating frame 6 and inserted into the sleeve 9, and the other side is connected to the hand wheel 11; wherein a slide groove 12 is opened on the base 1, a traction rod 13 and two springs 14 are embedded in the slide groove 12, springs 14 are connected to both sides of the traction rod 13, and the upper end of the traction rod 13 passes through the slide groove 12 and is connected to the rotating frame 6.

[0028] When in use, the cable is inserted between the fixed wheel 3 and the bending slot plate 7, and then the screw 10 is rotated by the hand wheel 11, so that the screw 10 pushes the sleeve 9 to rotate into the rotating frame 6, causing the adjusting frame 8 to push the bending slot plate 7 to rotate until the bending slot plate 7 is close to the cable, and then the hand wheel 11 is swung, and the rotating frame 6 rotates under the action of the rotating rod 2, so that the bending slot plate 7 bends the cable. During the bending process, the traction rod 13 moves with the rotating frame 6 in the slide groove 12, and the spring 14 is deformed. After the cable is bent and pulled out, the hand wheel 11 is released, and the rotating frame 6 returns to its initial position under the action of the spring 14 restoring its original state, so that the bending slot plate 7 also returns to its initial position, and returns to the initial position parallel to the fixed wheel 3, so that it is easier for the cable to enter again.

[0029] According to some embodiments of the present application, the traction rod 13 is optionally located in the center between the two springs 14. This makes it easier for the traction rod 13 to bring the rotating frame 6 back to the initial center position.

One side of the vertical rod 17 is connected to the stabilizing block 16, and the other side is connected to the triangular support 18. The triangular support 18 is provided with three arc edges, and the three arc edges support the ground at equal angles. The stabilizing block 16 is connected to the lower side of the base 1. The three arc edges of the triangular support 18 are in contact with the ground, and through the triangular stabilizing characteristics, the base 1 is not easily offset under the action of the triangular support 18, thereby making the cable bending process more stable.
