Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to a C-type insert plate steel pipe connector. Background Technology

[0002] Steel pipe tower transmission lines offer better ductility and load-bearing capacity than angle steel tower transmission lines. However, the higher manufacturing cost of the former limits its widespread adoption in transmission lines. One significant factor contributing to the high cost of steel pipe towers is the high cost of steel pipe connectors. Currently, flanges are commonly used for connecting steel pipes in steel pipe towers. Flange connections are divided into flexible flanges and rigid flanges. Flexible flanges have thinner flange plates, requiring numerous stiffening ribs welded between the flange plate and the steel pipe to prevent warping, resulting in a bulky and unsightly connection. Rigid flanges, on the other hand, have thicker flange plates and do not require stiffening ribs, resulting in a simpler and more aesthetically pleasing connection. To reduce welding workload, forged flanges are commonly used in steel pipe towers for transmission lines. Forged flanges are a type of rigid flange, offering an aesthetically pleasing structure and reliable load-bearing capacity, but their manufacturing cost is relatively high.

[0003] According to patent number CN202022219305.5, a C-shaped insert plate steel pipe connector includes a main pipe and an auxiliary pipe. The auxiliary pipe is fixed to the main pipe by a C-shaped connector. The C-shaped connector includes a ring plate welded to the main pipe. Connecting plates are welded to the left and right sides of the ring plate corresponding to the main pipe. The connecting plates are also welded to the main pipe. A placement groove is preset at the upper end of the auxiliary pipe. A C-shaped insert plate is inserted into the placement groove. The C-shaped insert plate is welded to the auxiliary pipe. Fastening screws are connected between the C-shaped insert plate and the auxiliary pipe. The C-shaped insert plate and the connecting plates are fixedly connected by bolts.

[0004] The above solution still has certain technical defects in actual use. Because the C-shaped insert plate has a through-type C-shaped structure, one side of the C-shaped insert plate bulges during installation, resulting in a large gap between the middle and the connecting plate. This causes misalignment between the auxiliary pipe and the connecting plate when installing the auxiliary pipe. Since the C-shaped insert plate and the connecting plate are only connected by bolts, they do not have a force-bearing contact point. This results in poor support between the C-shaped insert plate and the connecting plate at both ends of the auxiliary pipe. After long-term use, the bolt may bend, posing a certain safety hazard. Therefore, we propose a C-shaped insert plate steel pipe connector. Utility Model Content

[0005] The purpose of this utility model is to provide a C-type insert plate steel pipe connector to solve the existing problems mentioned in the background art.

A second C-shaped groove is provided at the top of the C-shaped insert plate. An auxiliary pipe is provided on the outer side of the second C-shaped groove. The end of the auxiliary pipe is spliced ​​with the second C-shaped groove through a pre-formed insertion groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a technical solution for a C-shaped insert plate steel pipe connector: including a main pipe 1, a C-shaped insert plate 5, and an auxiliary pipe 8. A ring sleeve 2 is fitted around the outer periphery of the main pipe 1. A connecting plate 3 protruding outward is fixedly installed around the outer periphery of the ring sleeve 2. The top and bottom ends of the connecting plate 3 are both provided with inclined surfaces. C-shaped insert plates 5 are provided on the outer side of the inclined surfaces at the top and bottom ends of the connecting plate 3. A first C-shaped groove 6 is provided at the bottom of the C-shaped insert plate 5. The first C-shaped groove 6 clamps the outer side of the inclined surfaces at the top and bottom ends of the connecting plate 3. A second C-shaped groove 7 is provided at the top of the C-shaped insert plate 5. An auxiliary pipe 8 is provided on the outer side of the second C-shaped groove 7. The end of the auxiliary pipe 8 is spliced ​​with the second C-shaped groove 7 through a plug-in groove 9.

[0021] Specifically, a contact platform 12 is provided at the junction of the first C-shaped groove 6 and the second C-shaped groove 7, and the end of the auxiliary pipe 8 extends to the contact platform 12 and is in close contact with the contact platform 12.

[0022] Specifically, the ring 2 is composed of two semi-circular ring structures spliced ​​together. The outer ends and middle of the two semi-circular ring structures are provided with connecting plates 3. The thickness of the connecting plates 3 at the outer ends of the semi-circular ring structures is half the thickness of the connecting plate 3 in the middle.

[0023] Specifically, filler blocks 10 are provided on both sides of the end of the auxiliary pipe 8, and the filler blocks 10 are filled on both sides of the insertion groove 9 by welding.

[0024] Specifically, the top, middle and bottom of the outer ring 2 are provided with reinforcing ribs 4, which are located between two adjacent connecting plates 3 and are fixedly connected to the connecting plates 3.

[0025] Specifically, the connecting plates 3 at both ends of the two semi-circular ring structures on the ring sleeve 2 are fixedly connected by bolts 11. The connecting plates 3 are fixedly connected to the C-shaped insert plate 5 by bolts 11, and the C-shaped insert plate 5 is fixedly connected to the auxiliary pipe 8 by bolts 11.

[0026] In this embodiment, a first C-shaped groove 6 and a second C-shaped groove 7 with different opening directions are respectively set at both ends of the C-shaped insert plate 5. The first C-shaped groove 6 contacts the top or bottom inclined surface of the connecting plate 3, so that the contact position between the inclined surface of the connecting plate 3 and the inner wall of the first C-shaped groove 6 forms a stress point. With the fixing of the bolt 11, the bearing capacity between the two is improved. The second C-shaped groove 7 is spliced ​​with the insertion groove 9 on the auxiliary pipe 8 and fixed with the bolt 11. At the same time, the contact platform 12 provides support for the end of the auxiliary pipe 8, thereby increasing the stress point between the auxiliary pipe 8 and the C-shaped insert plate 5, so that the stress can be distributed, thereby improving the supporting force of the C-shaped insert plate 5 and preventing the C-shaped insert plate 5 from transmitting the force to the bolt 11, which would cause the bolt 11 to deform or break.
