Description

Technical Field

[0001] The invention belongs to the technical field of power grid line cable maintenance, and in particular relates to an automatic wrapping machine for insulating tape of a cross-linked cable joint. Background Art

[0002] When a section of the cable is damaged, it is necessary to remove the faulty cable section and make a cable intermediate joint to reconnect the cables at both ends of the fault point. The wrapping cable intermediate joint is the most common cable connection method. An important construction link of the wrapping cable intermediate joint is the wrapping of the insulating tape. The final quality of the cable intermediate joint depends on the winding quality of the tape.

[0003] At present, the insulation tape wrapping of cable intermediate joints is mainly done manually. Because the process of making wrapped intermediate joints is relatively complicated, the on-site winding time is relatively long, the efficiency is low, and the technical and physical requirements of the construction workers are very high. In addition, manual wrapping cannot well control the wrapping tension, wrapping angle and wrapping speed, which will cause uneven distribution of insulation materials, which may affect the overall size, insulation performance and waterproof performance. Summary of the invention

[0004] In order to solve the above problems, the present invention provides an automatic wrapping machine for cross-linked cable joint insulating tape, which can realize the mechanized wrapping construction of cross-linked cable joint insulating tape. Based on the tension control of the wrapping tape and the firm support of the cable, the wrapping quality can be effectively guaranteed.

[0005] The present invention specifically relates to an automatic wrapping machine for insulating tape of a cross-linked cable joint, comprising a linear guide rail 1, a cable fixing frame 2, an anti-swing mechanism support 3, an anti-swing mechanism motor 4, an anti-swing mechanism pulley 5, a wrapping mechanism support 6, a wrapping mechanism main gear 7, a wrapping mechanism fixed pulley 8, an insulating tape fixed wheel 9, an insulating tape driving motor 10, an insulating tape 11, an insulating tape conducting wheel 12, a wrapping mechanism driving motor 13, a wrapping mechanism driving gear 14, a wrapping mechanism driving wheel 15, a wrapping mechanism driving belt 16, a wrapping mechanism driven wheel 17, and a wrapping mechanism driven gear 18.

[0006] Furthermore, the two cable fixing frames 2 are respectively fixed at both ends of the linear guide 1, the cable 0 is fixed on the two cable fixing frames 2, the anti-swing mechanism support 3 is fixed on the slide table of the linear guide 1, the three anti-swing mechanism motors 4 are arranged on the circular ring of the anti-swing mechanism support 3 in an axially symmetrical position, and the three anti-swing mechanism pulleys 5 are respectively fixed on the three anti-swing mechanism supports 3 through springs.

[0007] Furthermore, the wrapping mechanism support 6 is fixed on the slide table of the linear guide 1, an annular guide rail is arranged on the wrapping mechanism support 6, a plurality of wrapping mechanism fixed pulleys 8 axially symmetrically distributed are arranged on the wrapping mechanism main gear 7, and the wrapping mechanism main gear 7 is arranged on the annular guide rail of the wrapping mechanism support 6 through the wrapping mechanism fixed pulleys 8.

[0008] Furthermore, the insulating tape fixing wheel 9 and the insulating tape driving motor 10 are coaxially connected and fixed on the main gear 7 of the wrapping mechanism. The insulating tape 11 is placed on the insulating tape fixing wheel 9. The three insulating tape conducting wheels 12 are fixed on the main gear 7 of the wrapping mechanism. The insulating tape 11 passes through the three insulating tape conducting wheels 12 and is then wound around the cable 0.

[0009] Furthermore, the wrapping mechanism driving motor 13 is fixed on the slide of the linear guide 1, the wrapping mechanism driving gear 14 and the wrapping mechanism driving wheel 15 are coaxially connected and fixed on the wrapping mechanism support 6, the axes of the wrapping mechanism driving gear 14 and the wrapping mechanism driving wheel 15 are connected to the driving axis of the wrapping mechanism driving motor 13, the wrapping mechanism driven wheel 17 and the wrapping mechanism driven gear 18 are coaxially fixed on the wrapping mechanism support 6, the wrapping mechanism driven wheel 17 forms a power connection with the wrapping mechanism driving gear 14 through the wrapping mechanism driving belt 16, and the wrapping mechanism driving gear 14 and the wrapping mechanism driven gear 18 are respectively meshed with the wrapping mechanism main gear 7.

[0010] Furthermore, the annular structures of the anti-sway mechanism support 3 and the wrapping mechanism support 6, as well as the wrapping mechanism main gear 7 each have an opening to facilitate the clamping of the cable.

[0011] Furthermore, a force sensor is mounted on one of the insulating tape conducting wheels 12, which can be used to measure the tension of the insulating tape during the wrapping process.

[0012] Furthermore, the axes of the cable fixing frame 2, the circular ring of the anti-sway mechanism support 3, and the circular ring of the wrapping mechanism support 6 should coincide.

[0013] Furthermore, the cross-linked cable joint insulating tape automatic wrapping machine of the present invention has the following specific working process:

[0014] Control the wrapping mechanism driving motor 13 to make the wrapping mechanism main gear 7 open upward, control the three anti-swing mechanism motors 4 to drive the three anti-swing mechanism pulleys 5 to separate outward, fix the two ends of the cable 0 to be wrapped on the two cable fixing frames 2 respectively, control the three anti-swing mechanism motors 4 to drive the three anti-swing mechanism pulleys 5 to close toward the center, so that the three anti-swing mechanism pulleys 5 clamp the wrapped cable, place the insulating tape 11 on the insulating tape fixing wheel 9, and then lead the insulating tape 11 out, pass through the three insulating tape conducting wheels 12, and then be wound around the cable 0 for a certain number of times, so that the insulating tape 11 adheres to the cable 0.

[0015] The wrapping mechanism driving motor 13 is controlled to drive the wrapping mechanism driving gear 14 and the wrapping mechanism driving wheel 15 to rotate. At the same time, the wrapping mechanism driving wheel 15 will drive the wrapping mechanism driven wheel 17 and the wrapping mechanism driven gear 18 to rotate in the same direction through the wrapping mechanism driving belt 16. Since the wrapping mechanism driving gear 14 and the wrapping mechanism driven gear 18 are respectively engaged with the wrapping mechanism main gear 7, the wrapping mechanism main gear 7 will rotate in the opposite direction.

[0016] At the same time, the insulating tape driving motor 10 is controlled to drive the insulating tape fixing wheel 9 to rotate, and its rotation direction is opposite to the rotation direction of the main gear 7 of the wrapping mechanism to control the release of the insulating tape 11. At the same time, the insulating tape 11 will be wrapped around the cable 0, and the constant tension control during the wrapping process is performed through the feedback data of the force sensor on the insulating tape conduction wheel 12.

[0017] At the same time, the slider on the linear guide 1 is controlled to move at a constant speed so that the insulating tape 11 is laminated and wrapped along the axial direction of the cable 0. When one layer of wrapping is completed, the slider on the linear guide 1 is controlled to move in the opposite direction to start the second layer of wrapping. Since the three anti-swing mechanism pulleys 5 are respectively fixed on the three anti-swing mechanism motors 4 through springs, even if the diameter of the cable 0 changes, the three anti-swing mechanism pulleys 5 can still clamp the cable 0 and move stably due to the elastic force of the springs.

[0018] After wrapping is completed, the slider on the linear guide rail 1 is controlled to stop moving, the wrapping mechanism drive motor 13 and the insulating tape drive motor 10 are controlled to stop rotating, and the insulating tape 11 is cut between the cable 0 and the insulating tape reel.

[0019] The wrapping mechanism driving motor 13 is controlled to make the opening of the wrapping mechanism main gear 7 upward, and the three anti-swing mechanism motors 4 are controlled to drive the three anti-swing mechanism pulleys 5 to separate outward, and the wrapped cable 0 is removed from the cable fixing frame 2 to complete the automatic wrapping of the cross-linked cable joint insulating tape.

[0020] Compared with the prior art, the beneficial effects are:

[0021] (1) The wrapping mechanism provided by the present invention can effectively realize the mechanized wrapping of the insulating tape of the cross-linked cable joint. The force sensor attached thereto can obtain the tension of the tape in real time during the wrapping process to support the constant tension control of the wrapping process, thereby further ensuring the wrapping quality of the insulating tape of the cross-linked cable joint.

[0022] (2) The anti-sway mechanism provided by the present invention can effectively fix and support the cable, thereby preventing the swing of the cable during long-distance wrapping from affecting the wrapping quality of the insulating tape of the cross-linked cable joint.

[0035] The cross-linked cable joint insulating tape automatic wrapping machine of the present invention has the following specific working process:

[0036] Control the wrapping mechanism driving motor 13 to make the wrapping mechanism main gear 7 open upward, control the three anti-swing mechanism motors 4 to drive the three anti-swing mechanism pulleys 5 to separate outward, fix the two ends of the cable 0 to be wrapped on the two cable fixing frames 2 respectively, control the three anti-swing mechanism motors 4 to drive the three anti-swing mechanism pulleys 5 to close toward the center, so that the three anti-swing mechanism pulleys 5 clamp the wrapped cable, place the insulating tape 11 on the insulating tape fixing wheel 9, and then lead the insulating tape 11 out, pass through the three insulating tape conducting wheels 12, and then be wound around the cable 0 for a certain number of times, so that the insulating tape 11 adheres to the cable 0.

Since the three anti-swing mechanism pulleys 5 are respectively fixed on the three anti-swing mechanism motors 4 through springs, even if the diameter of the cable 0 changes, the three anti-swing mechanism pulleys 5 can still clamp the cable 0 and move stably due to the elastic force of the springs.
