Description

Technical Field

[0001] The utility model relates to the technical field of cement poles, in particular to an assembled cement pole. Background Art

[0002] Cement poles are high-strength steel-concrete columns that are cast with cement as the main material and steel bars as the skeleton. They are mainly used to support electric wires when they are installed and are commonly found in rural areas.

[0003] Cement poles can be divided into one-piece and assembled types according to different ways of use. The assembled type is generally a cement pole over 12 meters long. Because of its excessive length and inconvenience in transportation, it is set up in multiple sections and assembled at the actual installation site. The existing technology is to cast flanges at both ends of the assembled cement poles and install the flanges with bolts. However, in actual use, the overall force is large. When there is left and right shaking or a slight tilt of the foundation, the flange at the connection of the pole is hollow inside, and the lateral force can easily cause cement to break and separate from the cement pouring connection. At the same time, the bolts arranged in multiple circular arrays are installed vertically, which is inconvenient to install. At the same time, there will be axial force on the bolts when tilted, causing the nuts to loosen and slide, causing safety accidents. For this reason, a assembled cement pole is specially provided to solve the above problems. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0021] The embodiment of the present application provides an assembled cement pole to solve the problem that when the pole is actually used, the overall force is large. When the pole shakes left and right or the foundation is slightly tilted, the flange at the connection point of the pole is hollow inside and the lateral force easily causes the cement to break and separate at the connection point with the cement casting. At the same time, the bolts arranged in multiple circular arrays are installed vertically, which is inconvenient to install. At the same time, there will be axial force on the bolts when it is tilted, causing the nuts to loosen and slip.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The utility model embodiment discloses an assembled cement pole.

[0024] According to the attached Figure 1-4 As shown, it includes a steel-concrete cast cement pole 1 and flange connectors 2 cast and fixed at both ends of the steel-concrete cast cement pole 1, and a docking mechanism 3 is arranged inside the flange connector 2;

[0025] The docking mechanism 3 includes an assembly ring 31, a docking plug 32, a connecting post 33 and a split assembly clamp 34. The assembly ring 31 is integrally formed at the middle of the docking plug 32. The docking plug 32 is movably plugged into the interior of the flange connector 2. The connecting post 33 is fixedly welded to the side wall of the assembly ring 31, and the connecting post 33 passes through the flange connector 2. The split assembly clamp 34 is movably clamped on the outer wall of the connecting post 33.

[0026] The split assembly clamp 34 includes an outer clamp ring 341 and an inner clamp ring 342 , which are clamped on the inner and outer sides of the connecting column 33 , and the outer clamp ring 341 and the inner clamp ring 342 abut against the outer surface of the flange connector 2 .

[0027] The flange connector 2 includes a conical support portion 21, an annular connecting plate 22 and a columnar connecting portion 23. The annular connecting plate 22 and the columnar connecting portion 23 are integrally formed at both ends of the conical support portion 21. The columnar connecting portion 23 is fixedly cast inside the steel-concrete cast cement pole 1. The butt plug 32 is movably inserted in the columnar connecting portion 23. The connecting column 33 is movably inserted in the annular connecting plate 22. Annular grooves 35 are provided on the outer surfaces of both ends of the connecting column 33. The outer clamping ring 341 and the inner clamping ring 342 are movably inserted in the annular groove 35. The two sets of flange connectors 2 are clamped and installed. When the steel-concrete cast cement pole 1 shakes, the annular connecting plate 22 shakes up and down, and is tightened by the outer clamping ring 341 and the inner clamping ring 342, which will not cause loosening of the installed bolts.

[0028] The inner side of the inner clamp ring 342 is abutted against the outer surface of the conical support portion 21, and an assembly groove 343 is provided on the outer side of the inner clamp ring 342. The inner diameter of the assembly groove 343 is the same as the outer diameter of the connecting column 33. During installation, the inner clamp ring 342 is rotated so that the assembly groove 343 is opposite to the opening on the annular connecting plate 22. At this time, the connecting column 33 is inserted into the opening on the annular connecting plate 22, and then the inner clamp ring 342 is rotated so that the assembly groove 343 is shifted away. At this time, the inner clamp ring 342 is clamped into the inside of the annular groove 35 for fixation.

[0029] The two ends of the outer clamp ring 341 and the inner clamp ring 342 are respectively integrally formed with mounting strips 344, and locking bolts 345 are installed inside the mounting strips 344. When assembling every two sets of flange connectors 2, only two sets of split assembly clamps 34 are needed, so there are only four sets of locking bolts 345, which makes installation more convenient. At the same time, when the flange connector 2 shakes, the locking bolts 345 will not be subjected to force along the axial direction of the locking bolts 345, which can effectively prevent the nuts on the locking bolts 345 from loosening.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
