Description

Technical Field

[0001] The utility model relates to the technical field of electric power transmission line erection, in particular to a steel pipe pole structure for line erection. Background Art

[0002] With the sudden increase in urban electricity consumption, more and more 110kV high-voltage transmission lines will be built in urban areas. Since cable lines are expensive and cannot be widely used at present, overhead lines must be the main ones. The main characteristics of steel tube poles are large conductor cross-section, multiple voltages and circuits share the same pole, narrow corridors, often located beside the street or in isolated flower beds, and small root openings. Because steel tube poles occupy a small area and have beautiful shapes, they can be well integrated into the urban environment, so they are widely used in urban power supply construction. However, the load of transmission lines is getting higher and higher, and many ordinary steel tube poles can no longer withstand the load of high-voltage lines, especially at corners or terminals.

[0003] To improve the above problems, after searching, for example, a four-column steel pipe pole for high-voltage power transmission provided by patent announcement number CN203626360U includes: a pole body, which is formed by four steel pipe columns fixed by multiple horizontally arranged connecting parts; the connecting part is a square or rectangular frame, and its four corners are used to fix the four steel pipe columns of the pole body; a plurality of cross arms are provided at the upper part of the pole body for erecting transmission lines; the four corners of the connecting part are formed by a connecting part cylinder or a plurality of connecting part rings which are sleeved outside the steel pipe column and matched with the outer diameter of the steel pipe column; the steel pipe column is formed by multiple sections of steel pipes fixedly connected; the steel pipe is a seamless steel pipe or a straight seam welded pipe; every two sections of steel pipe can be fixedly connected by flanges; the inside of the square or rectangular frame of the connecting part is a grid structure formed by staggered steel pipes or steel rods; the four-column steel pipe pole can withstand a larger line load and can be used for the corners or terminals of the transmission line;

[0004] Another example is a single open-loop steel pipe pole for erecting power transmission and transformation lines disclosed in patent announcement number CN204663111U, which includes a vertically arranged main pipe, a plurality of cross arms arranged in the horizontal direction and connected to the main pipe at one end, the cross arms are arranged at different heights of the main pipe, each height position includes three cross arms, and the angle between the axes of two cross arms at each height position is 90°. The single open-loop steel pipe pole has a simple structure, beautiful appearance, and small footprint, and can be well applied to the needs of single open-loop lines and meet the needs of erecting power transmission lines.

[0005] Based on the above search, combined with the prior art, it is found that the steel pipe pole structure similar to the above disclosure in the prior art all uses flanges to connect multiple steel pipes. Since the steel pipes are large and heavy, it is difficult to align the flange holes between two steel pipes during installation, resulting in laborious installation. Therefore, a steel pipe pole structure for line erection is proposed to improve the above problem. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Reference Figure 1-4A steel pipe pole structure for line erection shown in the figure includes a steel pipe 1 and a connecting flange 2 fixedly installed at the end of the steel pipe 1. The steel pipe pole is formed by connecting multiple steel pipes 1 through the connecting flange 2. In order to facilitate the rapid installation between two steel pipes 1, this solution provides a positioning assembly including a fixing part 3 and a positioning sleeve 4 at one end of the steel pipe 1.

[0026] Specifically, the fixing member 3 is fixedly sleeved on the outer side of the steel pipe 1, the positioning sleeve 4 is installed on the side end of the fixing member 3 close to the connecting flange 2 on that side, and the positioning sleeve 4 extends toward one side of the connecting flange 2 on that side, and the inner diameter of the positioning sleeve 4 is consistent with the outer diameter of the connecting flange 2.

[0027] The positioning sleeve 4 can limit and align the two steel pipes 1, so as to facilitate the quick connection between the two steel pipes 1.

[0028] Among them, the inner edge of the end of the positioning sleeve 4 away from the fixing member 3 is set as a chamfer 401, so that the connecting flange 2 on one side of one steel pipe 1 has a certain fault tolerance during the insertion of the positioning sleeve 4 on the other steel pipe 1, and the insertion is smoother.

[0029] Among them, the fixing member 3 is annularly arranged and fixedly sleeved on the outer side of the steel pipe 1. The fixing member 3 is provided with connecting holes 301 corresponding to the flange holes on the connecting flange 2. The annular fixing member 3 can enhance the connection strength between the two steel pipes 1.

[0030] In addition, in order to facilitate the rapid alignment of the flange holes on the two connected connecting flanges 2, a hole alignment component 5 is installed on the fixing part 3, and the hole alignment component 5 includes a hole alignment slide rod 51 and a tension spring 52. The hole alignment slide rod 51 slides through one of the connecting holes 301, and the tension spring 52 is fixed between the hole alignment slide rod 51 and the end face of the fixing part 3 away from the positioning sleeve 4.

[0031] After the connecting flange 2 on one side of one of the steel pipes 1 is inserted into the positioning sleeve 4, it is rotated slightly. When one of the flange holes of the connecting flange 2 on the steel pipe 1 coincides with the hole-aligning slide rod 51, the hole-aligning slide rod 51 is inserted into the flange hole under the action of the tension spring 52, so that the flange holes on the two connected connecting flanges 2 are quickly aligned.

[0032] Similarly, the end of the hole-matching slide rod 51 away from the fixing member 3 is provided with a chamfer 53, so that the hole-matching slide rod 51 has a certain fault tolerance during the process of being inserted into the flange hole, and the insertion is smoother.

[0033] Furthermore, bearing members 6 are installed on the outer sides of both ends of the steel pipe 1, and support seats 7 are vertically installed on the outer walls of the bearing members 6. The support seats 7 can be used to place the two steel pipes 1 flat on the ground. At this time, the steel pipes 1 can be flexibly rotated, thereby facilitating the rapid alignment and connection operations between the two steel pipes 1.

[0034] The working principle of the utility model is as follows: two steel pipes 1 are placed flat on the ground using a support seat 7. At this time, the steel pipes 1 can be flexibly rotated so that the connecting flange 2 on one side of one of the steel pipes 1 is inserted into the positioning sleeve 4 on the other steel pipe 1, thereby realizing rapid alignment between the two steel pipes 1. Then, one of the steel pipes 1 is rotated slightly. When one of the flange holes of the connecting flange 2 on the steel pipe 1 coincides with the hole-matching slide bar 51, the hole-matching slide bar 51 is inserted into the flange hole under the action of a tension spring 52, thereby realizing rapid alignment of the flange holes on the two connected connecting flanges 2. The above operation is suitable for a construction method in which a plurality of steel pipes 1 are first installed on the ground and then erected and fixed to the ground. In addition, the steel pipe 1 at the bottom can be fixed on the ground first, and then the steel pipes 1 can be installed sequentially from bottom to top, still through the positioning sleeve 4 and the hole-matching slide bar 51 for rapid connection.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
