Description

Technical Field

[0001] This disclosure relates to fixed piles, specifically fixed piles used in conjunction with chain hoists to straighten 6-10kV concrete poles. Background Technology

[0002] When a 6-10kV concrete pole tilts in the field, if the pole is located in a low-lying area, has a puddle, or is in farmland, a pole straightening tool cannot usually be used to straighten the pole. Instead, a chain hoist must be used.

[0003] When using a chain hoist for straightening, one end of the chain hoist is fixed to the concrete pole, while the other end needs to be fixed to a ground anchor. Existing ground anchors have a steel rod structure at the bottom. During use, the anchor is driven into the ground using this rod, and then a sledgehammer is used to drive it deeper into the ground. Due to the soil characteristics of low-lying areas and the weight of the concrete poles themselves, straightening concrete poles requires stable anchoring performance from the ground anchors. Therefore, the anchors must be large and heavy, and driven deep enough to provide sufficient anchoring force. Obviously, after straightening, a considerable force is needed to pull out the anchors. Therefore, the financial and human resources consumed in the ground anchors during the entire construction process are substantial. Furthermore, the sledgehammer method easily deforms the anchors, reducing their reusability and further wasting materials. Additionally, it results in high labor intensity and low work efficiency for employees. Summary of the Invention

[0004] In view of this, this disclosure provides a fixing pile for straightening concrete utility poles, which solves the problems of existing insert-type anchor piles that require a sledgehammer to hammer for anchoring, and are difficult to pull out and easily deformed by hammering.

[0005] To solve the above-mentioned technical problems, the technical solution provided in this disclosure is that the fixing pile for straightening concrete utility poles includes a pile body, wherein: The lower end of the pile body is fixed with an anchor head; The anchoring head adopts a shovel head structure or a spade head structure; The angle between the anchor head and the pile body is less than 90°.

[0006] In this disclosure and possible embodiments, the included angle is 30 to 80°.

[0007] In this disclosure and possible embodiments, the included angle is 45 to 70°.

[0008] In this disclosure and possible embodiments, the anchoring head is pointed or rounded.

[0009] In this disclosure and possible embodiments, the anchor head is a flat body or an arc-shaped body.

[0010] In this disclosure and possible embodiments, the anchor head is connected to the pile body via a variable angle structure.

[0011] In this disclosure and possible embodiments, the variable angle structure includes a fastening bolt, a set nut, and a support base. The support base is fixed to the anchor head, and the lower end of the pile is locked to the support base by the fastening bolt and the set nut.

[0012] In this disclosure and possible embodiments, a chain hoist is provided on the pile body.

[0013] In this disclosure and possible embodiments, a pull ring is provided on the anchor head.

[0014] This disclosure has the following beneficial effects: The fixed pile for straightening concrete utility poles disclosed herein achieves pile anchoring through an anchoring head. This anchoring head employs a shovel or spade-like structure. Firstly, the shovel or spade-like structure allows for easy insertion into the soil, eliminating the need for a sledgehammer to hammer the pile. Secondly, during the straightening of concrete utility poles using a chain hoist, the shovel or spade-like structure, compared to the iron stake structure of ground anchors, provides a larger effective area under the same chain hoisting force. Therefore, to generate the same anchoring force, the anchoring head does not require the same insertion depth as existing ground anchors. This makes insertion and removal of the anchoring head easy and labor-saving, effectively improving work efficiency, reducing labor intensity, and preventing damage to the pile structure during straightening. It effectively solves the problems of existing insert-type anchor piles requiring a sledgehammer for anchoring, and the difficulties in extraction and deformation caused by hammering. Attached Figure Description

[0015] The above and other objects, features, and advantages of this disclosure will become clearer from the following description of embodiments with reference to the accompanying drawings, in which: Figure 1 This is a schematic diagram of the fixing pile structure for straightening concrete utility poles according to an embodiment of this disclosure; In the diagram: chain hoist connecting ring-1, pile body-2, support seat-3, pull ring-4, anchor head-5. Detailed Implementation

[0016] The present disclosure is described below based on embodiments; however, it is worth noting that the present disclosure is not limited to these embodiments. In the detailed description of the present disclosure below, certain specific details are described in detail. However, those skilled in the art will fully understand the present disclosure for the parts not described in detail.

[0017] Furthermore, unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to."

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0019] Specifically, Figure 1 This is a structural schematic diagram of the fixing pile used for straightening concrete utility poles in this embodiment, combined with... Figure 1 As shown, the fixing pile for straightening the concrete pole includes a pile body 2, and an anchor head 5 is fixed at the lower end of the pile body 2. The anchor head 5 adopts a shovel head structure or a spade head structure, and the included angle between the anchor head 5 and the pile body 2 is less than 90°.

[0020] As a preferred embodiment, the angle between the anchor head 5 and the pile body 2 is 30° to 80°. More preferably, the angle between the anchor head 5 and the pile body 2 is 45° to 70°.

[0021] In this embodiment, considering the magnitude of the anchoring force that can be provided for the anchoring head 5 with a shovel head structure or a spade head structure, it is obvious that if the width and height of the anchoring head 5 are larger, a greater anchoring force can be generated.

[0022] From the perspective of effort-saving when inserting the anchor head 5, the more pointed the head of the anchor head 5 is, the less effort is required. Obviously, a pointed or rounded shovel or spade head structure is more effort-saving than a square or flat head structure. In addition, the anchor head 5 body can be a flat body or an arc-shaped body. In this embodiment, an arc-shaped body is preferred.

[0023] During the straightening of concrete poles, the direction of the chain hoist's tension will vary greatly depending on the angle of inclination or the geological conditions of the area where the concrete pole is located. Therefore, the fixed pile in this embodiment is equipped with a variable angle structure. Through this variable angle structure, the angle between the pile body 2 and the anchor head 5 can be adjusted so that the pile body 2 can better adapt to the different tension directions of the chain hoist.

[0024] exist Figure 1 In this embodiment, the variable angle structure consists of fastening bolts, set nuts, and a support base 3. The support base 3 is welded and fixed to the anchor head 2, and the lower end of the pile body 2 is locked to the support base 3 by the fastening bolts and set nuts. When angle adjustment is required, the set nuts are loosened, the pile body 2 is rotated to the appropriate position, and then the set nuts are tightened again. Of course, other conventional methods can also be used for this variable angle structure, and this application does not limit it in this regard.

[0025] exist Figure 1 In this embodiment, a chain hoist connecting ring 1 is provided on the pile body 2. Preferably, the chain hoist connecting ring 1 is provided at the top of the pile body 2. Because with this configuration, when the chain hoist is connected to the chain hoist connecting ring 1, the chain hoist and the pile body 2 can be in a straight line, that is, the tension of the chain hoist is directly applied to the length direction of the pile body.

[0026] exist Figure 1 In this embodiment, a pull ring 4 is provided on the anchor head 5. Preferably, the pull ring 4 is located at the upper middle part of the anchor head 5. When the straightening process is completed and the anchor head 5 needs to be pulled out, the anchor head 4 can be pulled out by hand.

[0027] Specifically, the usage process of the fixed pile described in this invention is explained in detail below according to the embodiments of this disclosure: When using the concrete pole straightening fixing stake of this invention in the field, the fastening bolts and set nuts are loosened on site to make the pile body 2 and the anchor head 5 adjustable. Then, the anchor head 5 is inserted into the ground. To establish a more stable anchoring force, a pit can be dug in the ground beforehand, and then the anchor head 5 is inserted into the pit. After the anchor head 5 is fixed, the lower hook of the chain hoist used for straightening is hooked to the chain hoist connecting ring 1, and the upper hook of the chain hoist is connected to the inclined concrete pole by a steel wire rope.

[0028] During the straightening process, the chain hoist is pulled, and the pile body 2 of the fixed pile is tightened along with the chain hoist. When the two are on the same straight line, the locking nut is locked, and the angle between the pile body 2 and the anchor head 5 is fixed. Under the action of the chain hoist, the tilted concrete pole is straightened; after the concrete pole is straightened, the chain hoist is released, and the anchor head 4 of the fixed pile can be pulled out manually through the pull ring 4.

[0029] During the straightening construction, the process of manually driving the fixing piles into the ground with a sledgehammer is avoided, and the time and manpower required for extraction after use are also eliminated. In addition, if the fixing stake of a traditional fixing pile bends and cannot be reused, leaving it in the ground can easily damage agricultural machinery. Obviously, the fixing pile of this patent does not have this problem at all.

[0030] Furthermore, the fixed piles described in this invention have been specifically applied in the following locations, and the application results are as follows: (1) The No. 36 straight pole of the Yongsan Substation 81516 main line is tilted at 47 degrees. There is a low-lying water pit near the pole, so the pole straightening device cannot be used to straighten the pole. Only a chain hoist can be used to straighten the pole. With the help of the fixing pile of this invention, the tilted pole was straightened in 8 minutes and 16 seconds.

[0031] (2) The double poles of the 16203 branch of the 81221 main line of Song Erlian transformer were tilted. There was a low-lying water pit near the poles, so the pole straightening device could not be used to straighten the poles. Two chain hoists were used to straighten the poles. With the cooperation of two sets of fixing piles of this invention, the tilted poles were straightened in 10 minutes and 14 seconds.

[0032] (3) The 186 cable pole of the 81229 main line of Song Erlian transformer is tilted. There is a cornfield around it, so it is not possible to enter. The only way to straighten the pole is to use a chain hoist. The pole is straightened by using the fixed pile of this invention with an extended steel wire rope. The tilted pole was straightened in 7 minutes and 46 seconds.

[0033] Before using the fixing piles of this invention, when straightening utility poles using iron stake fixing piles, it required 9 workers to smash and pull out the iron stakes with a sledgehammer, resulting in a 64% damage rate of the iron stakes and an average pole straightening time of 32-48 minutes. Using the fixing piles of this invention, only 4 workers are needed, and the average pole straightening time is 8 minutes and 58 seconds. Furthermore, the straightening process does not damage the fixing piles, allowing for reuse and effectively reducing waste caused by damage. Therefore, field use has proven that the fixing piles of this invention can be used for special pole types such as straight poles, corner poles, and transformer platforms, with rapid on-site installation and significantly reduced labor intensity. In addition, these fixing piles are characterized by rapid assembly, convenient transport by small vehicles, and simple operation.

[0034] The embodiments described above are merely illustrative of implementation methods of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent disclosure. It should be noted that those skilled in the art can make various modifications, equivalent substitutions, and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent disclosure should be determined by the appended claims.
