Description

Technical Field

[0001] This utility model relates to a large obtuse angle crossbeam and a steel pipe pole, belonging to the field of steel pipe pole equipment. Background Technology

[0002] Currently, the crossarms used in steel pipe poles are mainly straight or wing-shaped. The crossarm hanging point is at the same height as the crossarm installation position or the hanging point is within 500mm above the crossarm installation height. This means that the main pipe and the crossarm hanging point need to be at roughly the same height, resulting in a higher overall design height of the main pipe, a larger tonnage, and a significant reduction in economic efficiency.

[0003] Taking the common goose-wing type crossarm as an example, the arc shape of the crossarm is used to raise the position of the hanging point at the end of the crossarm. The arc shape of the goose-wing type crossarm is difficult to process, and it needs to be bent by baking with a hot air gun. It is not suitable for high voltage levels of 110kV and above. The processing technology is complicated and the processing efficiency is low. The lifting height of the hanging point position of the goose-wing type crossarm is limited, with a maximum height of 0.5 meters. The effect on reducing the overall height of the main pipe is not obvious, and the weight reduction effect is negligible. It has the problems of complex design, high manufacturing cost and limited lifting of the hanging point position. It cannot effectively reduce the total height and tonnage of the main pipe, resulting in low economic benefits.

[0004] To address the aforementioned issues, this application proposes a large obtuse angle crossbeam and a steel pipe pole. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a large obtuse angle crossbeam and steel pipe pole, which has the advantages of convenient processing and effective weight reduction, effectively reducing the overall cost of steel pipe poles, and can effectively solve the problems in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A large obtuse angle crossarm, installed on a steel pipe pole, includes a first crossarm section and a second crossarm section in a fixed assembly;

[0008] The first crossbeam section is inclined upwards and has a constant diameter. The second crossbeam section is horizontal and tapered. The cross sections of the first and second crossbeam sections are quadrilateral, hexagonal, or octagonal.

[0009] The end of the first crossarm segment is fixedly connected to the end of the second crossarm segment, and the first crossarm segment and the second crossarm segment form an included angle A, the included angle A being set to a range of 110°-170°.

[0010] As a further improvement of this utility model, a crossarm connecting seat is fixedly connected to the bottom end of the first crossarm segment. The crossarm connecting seat is connected to the crossarm mounting seat on the steel pipe pole, and is used to install the large obtuse angle crossarm on the steel pipe pole.

[0011] As a further improvement of this utility model, a hanging plate is fixedly installed on the second crossarm section away from the first crossarm section. The hanging plate is used to install hardware to connect the power line.

[0012] As a further improvement of this utility model, the included angle A is set to 120°-150°.

[0013] As a further improvement of this utility model, the included angle A is set to 135°.

[0014] As a further improvement of this utility model, the first crossbeam segment and the second crossbeam segment are fixedly connected by a connecting part.

[0015] As a further improvement of this utility model, the connecting part is configured as a weld, and the first crossarm segment and the second crossarm segment are connected by welding.

[0016] As a further improvement of this utility model, the connecting part is configured as a flange, and the first crossarm section and the second crossarm section are connected by a flange.

[0017] In addition, a steel pipe pole is disclosed, including the aforementioned large obtuse angle crossarm, including a pole body, on which a crossarm mounting seat is fixedly connected, and the crossarm connecting seat is fixedly connected to the crossarm mounting seat by bolts.

[0018] As a further improvement of this utility model, at least one of the aforementioned crossarm mounting seats is disposed at the top of the pole body.

[0019] This utility model has at least one of the following beneficial effects:

[0020] 1. The crossarm adopts a two-section design, both sections are straight in shape, and the included angle between the two sections is a large obtuse angle design. The obtuse angle can be adjusted according to the diameter of the crossarm pipe to facilitate processing. Compared with the arc shape of the goose wing crossarm, it effectively reduces the processing cost.

[0021] 2. By using a two-section design, the height difference between the crossarm hanging point and the crossarm installation point can reach more than 1.5 meters, which effectively increases the height of the conductor above the ground. This allows for an increase in the distance between the conductor and the ground without increasing the height of the pole, meeting the design specifications for the safe distance between the conductor and the ground. At the same time, it can effectively reduce the weight of the pole by more than 10%.

[0022] 3. The first crossarm section adopts a constant diameter design to strengthen the strength of the crossarm root and meet the strength requirements of high voltage levels of 110kV and above. The second crossarm section adopts a tapered cross section design to reduce the weight of the crossarm while meeting the strength requirements, making it more economical. At the same time, the second crossarm section is designed horizontally to reduce the processing difficulty and ensure that the load force at the hanging point acts on the axis of the pole, making the overall load force distribution of the crossarm more uniform and reasonable.

[0031] Example

[0032] like Figures 1-4 As shown, a large obtuse angle crossarm is installed on a steel pipe pole, including a first crossarm pole section 2 and a second crossarm pole section 3 that are fixedly assembled.

[0033] The first crossarm section 2 is inclined upwards and has a constant diameter. The second crossarm section 3 is installed horizontally and is tapered. The cross-sections of the first crossarm section 2 and the second crossarm section 3 are quadrilateral, hexagonal, or octagonal. The cross-sectional shapes of the first crossarm section 2 and the second crossarm section 3 are the same. That is, when the first crossarm section 2 has a hexagonal cross-section, the second crossarm section 3 also has a hexagonal cross-section. Along the direction away from the first crossarm section 2, the cross-sectional size of the second crossarm section 3 gradually decreases and becomes tapered.

[0034] The end of the first crossbeam segment 2 is fixedly connected to the end of the second crossbeam segment 3, and an included angle A is formed between the first crossbeam segment 2 and the second crossbeam segment 3. The included angle A is set to a range of 110°-170°.

[0035] By setting the included angle A to a large obtuse angle, the height of the crossarm can be effectively increased without increasing the height of the steel pipe pole. The crossarm hanging point on the second crossarm pole segment 5 is higher than the crossarm installation position on the steel pipe pole, which effectively increases the conductor's height to the ground. This allows for an increase in the conductor's distance to the ground without increasing the pole height, meeting the design specifications for the conductor's safe distance to the ground. At the same time, it can effectively reduce the pole weight by more than 10%.

[0036] In addition, the first crossbeam segment 2 and the second crossbeam segment 3, which are arranged in quadrilateral, hexagonal or octagonal shapes, can be formed by bending a whole plate, resulting in a straight shape, simple structure, high strength and easy processing.

[0037] The first crossarm section 2 adopts a constant diameter design to strengthen the strength of the crossarm root and meet the strength requirements of high voltage levels of 110kV and above. The second crossarm section 3 adopts a tapered cross section design to reduce the weight of the crossarm while meeting the strength requirements, making it more economical. At the same time, the second crossarm section 3 is designed horizontally to reduce the difficulty of processing and ensure that the load force at the hanging point acts on the axis of the pole, making the overall load force distribution of the crossarm more uniform and reasonable.

[0038] In some alternative embodiments, the bottom end of the first crossarm segment 2 is fixedly connected to a crossarm connecting seat 1, which is connected to a crossarm mounting seat 7 on the steel pipe pole, for installing the large obtuse angle crossarm on the steel pipe pole.

[0039] In some alternative embodiments, a hanging plate 5 is fixedly installed on the second crossarm segment 3 away from the first crossarm segment 2. The hanging plate 5 has a mounting hole 51 for installing power fittings, and the hanging plate 5 is used to install fittings to suspend the power line.

[0040] Optionally, the included angle A is set to 120°-150°.

[0041] As a preferred embodiment, the included angle A is set to 135°.

[0042] Adjust the included angle A reasonably according to the actual distance of the conductor to be raised to the ground and the diameter of the crossarm.

[0043] In some alternative embodiments, the first crossarm segment 2 and the second crossarm segment 3 are fixedly connected by a connecting part 4.

[0044] For example, the connecting part 4 is set as a weld, and the first crossarm section 2 and the second crossarm section 3 are connected by welding. When the height of the steel pipe pole is low, direct welding can be used. When the height of the steel pipe pole is high, a welding plate is added between the first crossarm section 2 and the second crossarm section 3, and welded to the first crossarm section 2 and the second crossarm section 3 respectively, thereby improving the structural strength of the weld.

[0045] Alternatively, the connecting part 4 can be configured as a flange, with the first crossarm section 2 and the second crossarm section 3 connected by a flange. A flange is fixedly welded to the end of the first crossarm section 2 away from the steel pipe pole, and another matching flange is welded to the end of the second crossarm section 3 near the first crossarm section 2. The two flanges are fixedly connected by bolts to achieve a fixed connection between the first crossarm section 2 and the second crossarm section 3.

[0046] In addition, a steel pipe pole is disclosed, including the aforementioned large obtuse angle crossarm, including a pole body 6, on which a crossarm mounting seat 7 is fixedly connected. The crossarm mounting seat 7 has a second bolt hole 71 that matches the first bolt hole 11 on the crossarm connecting seat 1. The crossarm connecting seat 1 is fixedly connected to the crossarm mounting seat 7 by bolts. The crossarm mounting seat 7 can be set as a commonly used insert plate in the prior art. When the height of the steel pipe pole is low, the crossarm mounting seat 7 can also be directly welded to the outer surface of the steel pipe pole and reinforced with reinforcing ribs.

[0047] As a further improvement of this utility model, at least one of the crossarm mounting seats 7 is provided on the top of the pole body 6, which effectively increases the height of the conductor above the ground, thereby increasing the distance of the conductor above the ground without increasing the height of the pole body and reducing the overall weight of the steel pipe pole.

[0048] The above are preferred embodiments of the present invention. The basic principles, main features, and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope thereof. All such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
