Description

Technical Field

[0001] The invention relates to a segmented assembled electric pole device for training in the field of electric power construction training. Background Art

[0002] The segmented connection technology of steel pipe poles is one of the core technologies for the construction of electric poles. There are two types of connection structures for segmented steel pipe poles: socket type and flange type. The socket type, as the name implies, sockets two sections of tapered steel pipe poles, and is characterized by being installed in place at one time and cannot be adjusted. There are technical requirements such as overlapping surfaces and straightening during installation. The flange type connection connects the flange surfaces of the two sections of the poles together through multiple bolts and nuts. Its characteristic is that the angle between the two flange surfaces can be adjusted by rotating the nuts, thereby achieving the adjustment of the pre-bias of the pole. These two structures and related technologies are key in the construction of steel pipe poles, so they must be faithfully demonstrated and implemented in training to ensure the training effect. In the prior art, the two connection structure forms are trained separately, which is inefficient and requires two sets of devices to be matched respectively. The storage, transportation and setting of the devices are relatively cumbersome. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a segmented assembled pole device for training, which realizes the connection of two structures on the same steel pipe pole, greatly simplifying the connection training of the segmented connection structure of the steel pipe pole.

[0004] A technical solution to achieve the above object is: a segmented assembled pole device for training, comprising a pile foundation, a steel pipe foundation and a nested steel pipe;

[0005] The pile foundation is fixedly arranged on the ground surface, the upper surface of the pile foundation is the pile foundation flange surface, a plurality of bolts are evenly distributed on the connection circumferential surface of the pile foundation flange surface, the lower part of the bolt is fixed to the pile foundation flange surface by a fastening nut, and the upper part of the bolt is provided with an adjustable limit nut;

[0006] The lower surface of the steel pipe foundation is a steel pipe foundation flange surface, and a guide pipe is provided on the steel pipe foundation flange surface corresponding to any of the bolts, the guide pipe is sleeved on the bolt, and is supported and limited by the limiting nut, and a sleeper is padded between the steel pipe foundation flange surface and the pile foundation flange surface;

[0007] The upper end of the steel pipe base is a sleeve-type steel pipe structure, and the nested steel pipe is detachably sleeved on the outer side of the sleeve-type steel pipe structure.

[0008] Furthermore, the fastening nut includes an upper fastening nut and a lower fastening nut, and the upper fastening nut and the lower fastening nut respectively fix the bolt from both sides of the pile foundation flange surface.

[0009] Furthermore, reinforcing ribs are provided between the steel pipe base flange surface and the steel pipe base.

[0010] Furthermore, the taper of the nested steel pipes is 1 / 60, and the height of the nested steel pipes is 3.5m.

[0011] Furthermore, the length of the overlapping portion of the nested steel pipe and the sleeve-type steel pipe structure is at least 40 cm.

[0012] The present invention provides a segmented assembled pole device for training, wherein the pile foundation and the lower end of the steel pipe foundation are connected by flanges, which are used for training on flange connection of steel pipe poles and pre-bias adjustment of flange connection of steel pipe poles; the upper end of the steel pipe foundation and the nested steel pipe are connected by sockets, which are used for training on socket connection of steel pipe poles. The device is designed for training with good practicality, convenient operation and good safety. The two segments already include two representative connection methods, so there is no need to add other segments to achieve the height of a full-size pole in actual production. The overall device has a simple structure and is easy to store, carry and set up. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 The present invention is a schematic diagram of the connection structure of a steel pipe base and nested steel pipes of a segmented assembled pole device for training. DETAILED DESCRIPTION

[0015] In order to better understand the technical solution of the present invention, the following is a detailed description through specific embodiments:

[0016] See also Figure 1 and Figure 2 A segmented assembled pole device for training of the present invention comprises a pile foundation 1, a steel pipe foundation 2 and a nested steel pipe 3.

[0017] See also Figure 1, the pile foundation is fixed on the ground surface. The upper surface of the pile foundation 1 is the pile foundation flange surface 11. Six bolts 12 are evenly arranged on the connecting circumferential surface of the pile foundation flange surface 11. In order to facilitate training and simplify the preparation process before training, the bolts 12 are semi-permanently fixed on the pile foundation flange surface 11. For any bolt 12, an upper fastening nut 13 and a lower fastening nut 14 are used to fix the bolt 12 from both sides of the pile foundation flange surface 11 respectively to ensure that the bolt 12 will not move up and down once it is positioned. An adjustable limit nut 15 is provided on the upper part of the bolt, and the limit nut 15 is adjusted up and down by rotation, and a washer surface is provided on the limit nut 15. The lower surface of the steel pipe base 2 is the steel pipe base flange surface 21, and a guide tube 22 is provided on the steel pipe base flange surface 21 corresponding to any bolt 12.

[0018] When the steel pipe foundation 2 is flange-connected to the pile foundation 1, it is necessary to lift the steel pipe foundation 2, align the guide pipe 22 with the bolt 12 one by one, and then place it downward to support it through the washer surface of the limit nut 15. This structural form can ensure that realistic steel pipe rod flange connection training can be carried out under the condition that the bolt 12 is semi-permanently fixed. When pre-bias adjustment training of steel pipe rod flange connection is required, it can be achieved by adjusting the height of the limit nut 15 on one side. The pile foundation flange surface 11 is padded with sleepers 4 for the steel pipe foundation 2 to abut against, to prevent the steel pipe foundation 2 from tipping over due to operational errors of the training personnel.

[0019] See also Figure 2 , the upper end of the steel pipe base 2 is a sleeve-type steel pipe structure 24, and the nested steel pipe 3 is detachably sleeved on the outside of the sleeve-type steel pipe structure 24. After the flange connection between the pile foundation 1 and the steel pipe base 2 is completed and the structural stability is ensured, the nested steel pipe 3 and the steel pipe base 2 are sleeved in the pile foundation. In order to ensure the structural strength of the steel pipe base 2, a reinforcing rib 23 is provided between the flange surface 21 of the steel pipe base and the pipe body of the steel pipe base 2. The taper of the nested steel pipe 3 is 1 / 60, and the height of the nested steel pipe 3 is 3.5m. The length d of the overlapping part of the nested steel pipe 3 and the sleeve-type steel pipe structure is at least 40cm. Although the height of the steel pipe base 2 and the nested steel pipe 3 cannot reach the height of a standard pole, in consideration of the practicality of training, ease of operation and safety, the two sections have already included two representative connection methods. Therefore, there is no need to add other sections in order to reach the height of a full-size pole in actual production.

[0020] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
