Description

Technical Field

[0001] This utility model relates to the field of iron tower transmission line technology, and in particular to an iron tower transmission line connection device. Background Technology

[0002] Transmission line connection devices are mainly used to ensure a secure connection between transmission lines and power towers, thereby guaranteeing the safety and stability of power transmission. The connection device uses components such as clamps and threaded rods to fix the transmission line to the hanging end, preventing the line from detaching from the tower due to external forces and ensuring the normal delivery of electrical energy.

[0003] However, in the existing technology, the connection device for the transmission line of the iron tower is usually fixed by multiple bolts, which is very inconvenient to install and disassemble. Workers need to use tools to unscrew the bolts. Since the work is done in the air, the bolts may fall from the height, which greatly increases the installation time. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a transmission line connection device for a transmission tower, comprising: a partial truss structure of the transmission tower, a connecting plate fixedly installed on the bottom surface of the partial truss structure, an insulator fixedly installed on the bottom surface of the connecting plate, a connecting block fixedly installed on the bottom surface of the insulator, a U-shaped plate fixedly installed on the bottom surface of the connecting block, a clamping assembly provided between the inner walls of the two sides of the U-shaped plate, a limiting assembly provided on one side surface of the clamping assembly, the clamping assembly including a bidirectional threaded rod, the bidirectional threaded rod being connected between the inner walls of the two sides of the U-shaped plate through a bearing, one end of the bidirectional threaded rod movably penetrating through the inner wall surface of one side of the U-shaped plate, and a rotating handle fixedly installed on one end surface of the bidirectional threaded rod, the rotating handle being located on the outside of the U-shaped plate.

[0006] Furthermore, the top inner wall surface of the U-shaped plate is provided with a long groove, and the outer wall of the bidirectional threaded rod is threadedly connected to two movable plates. The bottom surface of the two movable plates is fixedly installed with arc-shaped clamps, and the inner wall surface of the two arc-shaped clamps is uniformly fixedly installed with multiple anti-slip strips. The top surface of the two movable plates is fixedly installed with sliders, and the two sides of the two sliders are correspondingly and movably fitted to the inner wall surfaces of the two sides of the long groove.

[0007] Furthermore, the limiting component includes multiple limiting holes, which are arranged around one side surface of the rotating handle. A T-slot is provided at one end of the top surface of the U-shaped plate, and a box cover is fixedly installed on the top surface of the U-shaped plate, with the box cover located above the T-slot.

[0008] Furthermore, a T-shaped plate is movably fitted inside the T-slot, and a limiting rod is fixedly installed on one side surface of the T-shaped plate. The limiting rod movably fits through one side inner wall surface of the box cover and is inserted into one of the limiting holes.

[0009] Furthermore, a pull rod is fixedly installed on the other side surface of the T-shaped plate. The pull rod moves through the inner wall surface of the other side of the box cover. A pull ring is fixedly installed on the end surface of the pull rod away from the T-shaped plate. The pull ring is located on the outside of the box cover. Two grooves are formed on the outer wall surface of the pull rod.

[0010] Furthermore, a spring is fixedly installed between the other side surface of the T-shaped plate and the other side inner wall surface of the box cover, and the pull rod is located inside the spring.

[0011] Furthermore, a rectangular groove is formed on one side surface of the box cover, and vertical rods are fixedly installed on the inner walls of the upper and lower sides of the rectangular groove. An L-shaped plate is movably fitted onto the surface of the vertical rod, and the two sides of the L-shaped plate are movably fitted onto the inner walls of the two sides of the rectangular groove. One end of the L-shaped plate is movably installed inside one of the grooves.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, the L-shaped plate is first pushed upwards, causing it to move upwards on the surface of the vertical rod. The L-shaped plate moves out of one of the grooves. Then, the pull ring is pulled, which moves the pull rod. The pull rod moves the T-shaped plate inside the T-slot. The movement of the T-shaped plate compresses the spring. At the same time, the movement of the T-shaped plate moves the limiting rod, which moves out of the limiting hole. Then, the L-shaped plate is inserted into another groove to restrict the movement of the limiting rod, thereby releasing the restriction on the rotating handle.

[0014] Rotating the handle causes the double-sided threaded rod to rotate, which in turn moves two movable plates in opposite directions. This movement of the movable plates then moves two arc-shaped clamping plates. When the distance between the two arc-shaped clamping plates is greater than the diameter of the wire, the wire can be placed between the two arc-shaped clamping plates. Rotating the handle in the opposite direction moves the two arc-shaped clamping plates closer to each other. The two arc-shaped clamping plates, along with multiple anti-slip strips, firmly clamp and fix the wire. At this point, pulling the L-shaped plate upwards utilizes the spring's rebound force to reset the T-shaped plate, thereby allowing the limiting rod to be re-inserted into the corresponding limiting hole. This restricts the rotation of the double-sided threaded rod, achieving the purpose of installing the wire.

[0015] With the above structure in place, workers only need to release the limit of the rotating handle and rotate the double-threaded rod to install or remove the wires without the need for tools, which greatly saves the time required for wire installation or removal. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-9 This utility model provides a technical solution: a transmission line connection device for iron towers, comprising: a partial truss structure 1 of the iron tower, a connecting plate 2 fixedly installed on the bottom surface of the partial truss structure 1, an insulator 3 fixedly installed on the bottom surface of the connecting plate 2, a connecting block 4 fixedly installed on the bottom surface of the insulator 3, a U-shaped plate 5 fixedly installed on the bottom surface of the connecting block 4, a clamping assembly 6 provided between the inner walls of the two sides of the U-shaped plate 5, a limiting assembly 7 provided on one side surface of the clamping assembly 6, the clamping assembly 6 including a bidirectional threaded rod 601, the bidirectional threaded rod 601 being connected between the inner walls of the two sides of the U-shaped plate 5 by bearings, one end of the bidirectional threaded rod 601 movably penetrating the inner wall surface of one side of the U-shaped plate 5, and a rotating handle 602 fixedly installed on the surface of one end of the bidirectional threaded rod 601, the rotating handle 602 being located on the outside of the U-shaped plate 5.

[0029] Specifically: the partial truss structure 1 of the iron tower is a truss installed and connected on the surface of the iron tower for erecting power transmission lines. This part of the truss is shown here; the insulator 3 serves to prevent the power transmission from the power line to the iron tower, and the rotating handle 602 serves to drive the bidirectional threaded rod 601 to rotate.

[0030] In one embodiment, the top inner wall surface of the U-shaped plate 5 is provided with a long groove 603, and the outer wall of the bidirectional threaded rod 601 is threadedly connected to two movable plates 604. The bottom surfaces of the two movable plates 604 are fixedly installed with arc-shaped clamps 605, and the inner wall surfaces of the two arc-shaped clamps 605 are evenly fixedly installed with multiple anti-slip strips. The top surfaces of the two movable plates 604 are fixedly installed with sliders 606, and the two sides of the sliders 606 are correspondingly and movably attached to the two sides of the inner wall surface of the long groove 603.

[0031] Specifically, such as Figure 2-4 As shown: Multiple anti-slip strips are fixedly installed on the inner wall surfaces of the two arc-shaped clamping plates 605 (not shown in the figure). The two arc-shaped clamping plates 605, together with the multiple anti-slip strips, play a role in firmly clamping and fixing the wires. The two sliders 606 are movably attached to the inside of the long groove 603, which plays a role in ensuring the stable movement of the two movable plates 604. The two movable plates 604 move with the help of the bidirectional threaded rod 601, the two sliders 606 and the long groove 603.

[0032] In one embodiment, the limiting component 7 includes a plurality of limiting holes 701, which are formed around one side surface of the rotating handle 602. A T-groove 702 is formed at one end of the top surface of the U-shaped plate 5. A cover 703 is fixedly installed on the top surface of the U-shaped plate 5, and the cover 703 is located above the T-groove 702.

[0033] Specifically, such as Figure 5-6 As shown: The cover 703 serves to seal the T-groove 702, preventing rainwater from entering the T-groove 702 and causing the spring 712 to rust and become unusable.

[0034] In one embodiment, a T-shaped plate 704 is movably fitted inside the T-slot 702, and a limiting rod 705 is fixedly installed on one side surface of the T-shaped plate 704. The limiting rod 705 movably fits through one side inner wall surface of the cover 703 and is inserted into one of the limiting holes 701.

[0035] Specifically, such as Figure 6 As shown: The limiting rod 705, together with the limiting hole 701, serves to prevent the rotating handle 602 from rotating.

[0036] In one embodiment, a pull rod 706 is fixedly installed on the other side surface of the T-shaped plate 704. The pull rod 706 moves through the inner wall surface of the other side of the box cover 703. A pull ring 707 is fixedly installed on the end surface of the pull rod 706 away from the T-shaped plate 704. The pull ring 707 is located on the outside of the box cover 703. Two grooves 708 are formed on the outer wall surface of the pull rod 706.

[0037] Specifically, such as Figure 6 and 8 As shown: the pull ring 707 drives the pull rod 706 to move, and the pull rod 706 drives the T-shaped plate 704 to move inside the T-shaped groove 702.

[0038] In one embodiment, a spring 712 is fixedly installed between the other side surface of the T-shaped plate 704 and the other side inner wall surface of the box cover 703, and the pull rod 706 is located inside the spring 712.

[0039] Specifically, such as Figure 6 As shown: Spring 712 restricts the position of T-plate 704 inside T-slot 702, thereby preventing the limiting rod 705 from dislodging from the limiting hole 701.

[0040] In one embodiment, a rectangular groove 709 is formed on one side surface of the cover 703. Vertical rods 710 are fixedly installed on the inner wall surfaces of the upper and lower sides of the rectangular groove 709. An L-shaped plate 711 is movably fitted onto the surface of the vertical rod 710. The two sides of the L-shaped plate 711 are movably fitted onto the inner wall surfaces of the two sides of the rectangular groove 709. One end of the L-shaped plate 711 is movably installed inside one of the grooves 708.

[0041] Specifically, such as Figure 9 As shown: The L-shaped plate 711 is inserted into the two grooves 708. When it is inserted into the right groove 708, it can prevent the compressed spring 712 from returning to its original position, thereby limiting the movement of the limit rod 705.

[0042] Working principle:

[0043] When using this tower transmission line connection device, first push the L-shaped plate 711 upward, so that the L-shaped plate 711 moves upward on the surface of the vertical rod 710. The movement of the L-shaped plate 711 causes it to move out of the inside of one of the grooves 708. Then pull the pull ring 707. The movement of the pull ring 707 drives the pull rod 706 to move. The movement of the pull rod 706 causes the T-shaped plate 704 to move inside the T-slot 702. The movement of the T-shaped plate 704 will squeeze the spring 712, thereby compressing the spring 712. At the same time, the movement of the T-shaped plate 704 drives the limit rod 705 to move. The movement of the limit rod 705 causes it to move out of the inside of the limit hole 701. Then insert the L-shaped plate 711 into the inside of another groove 708 to restrict the movement of the limit rod 705, thereby releasing the restriction on the rotating handle 602.

[0044] At this point, rotating the handle 602 causes the bidirectional threaded rod 601 to rotate. The rotation of the bidirectional threaded rod 601 causes the two movable plates 604 to move in opposite directions. The movement of the two movable plates 604 causes the two arc-shaped clamping plates 605 to move. When the distance between the two arc-shaped clamping plates 605 is greater than the diameter of the wire, the wire can be placed between the two arc-shaped clamping plates 605. Rotating the handle 602 in the opposite direction causes the two arc-shaped clamping plates 605 to move closer to each other. The two arc-shaped clamping plates 605, together with multiple anti-slip strips, firmly clamp and fix the wire. At this point, pulling the L-shaped plate 711 upwards will use the rebound force of the spring 712 to reset the T-shaped plate 704, thereby allowing the limiting rod 705 to be re-inserted into the corresponding limiting hole 701, thus limiting the rotation of the bidirectional threaded rod 601 and achieving the purpose of installing the wire.

[0045] With the cooperation of the above structure, the staff only needs to release the limit of the rotating handle 602 and rotate the bidirectional threaded rod 601 to install or remove the wires without the need for tools, which greatly saves the time required for wire installation or removal.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
