Description
Technical Field
[0001] This utility model relates to the technical field of power operations, and in particular to a safety hanging point structure for utility poles. Background Technology
[0002] In industries such as power and communications, it is often necessary to climb to the height of utility poles to perform work. Therefore, it is necessary to install safety belt attachment points on the utility poles, and workers wear safety belts that are attached to the safety belt attachment points to increase the safety of the work.
[0003] Due to the structural characteristics of utility poles and the limitations of the site environment, the methods for setting up attachment points for pole work are relatively limited. Workers often find it difficult to find suitable attachment points for high-mounting and low-use operations. Some workers directly attach safety belts to the crossarms or other auxiliary facilities of the utility pole, but these locations may have insufficient strength or be unsuitable, failing to meet the safety requirements of high-mounting and low-use operations.
[0004] While some auxiliary hanging point devices exist on the market, most suffer from drawbacks such as complex installation, poor versatility, and low reliability, making them difficult to widely apply in actual operations. For example, some magnetic hanging point devices lack sufficient adhesion to smooth utility pole surfaces and are prone to falling off; while some binding hanging point devices may damage the utility pole and consume a lot of time and effort during installation and removal. Summary of the Invention
[0005] The purpose of this invention is to provide a safety attachment point structure for utility poles, which allows for easy attachment of safety belts to the poles, thereby improving the safety of pole-based operations.
[0006] This utility model provides a safety hanging point structure for utility poles, the safety hanging point structure including a screw base, a screw hook and a fastening bolt; the screw base is in the shape of an arc that fits against the utility pole, and the screw base is fixedly connected to the utility pole; The screw hook includes a first threaded portion and a hanging ring, the hanging ring being integrally connected to the first threaded portion and used for attaching a seat belt; the screw base is provided with a second threaded portion that is screwed into the first threaded portion. The screw base has a mounting hole that penetrates the screw base; the utility pole has a threaded hole, and the fastening bolt passes through the mounting hole and is screwed into the threaded hole.
[0007] Furthermore, the screw base is provided with a plurality of mounting holes, the utility pole is provided with a plurality of threaded holes, the mounting holes and the threaded holes correspond one-to-one, and a plurality of fastening bolts are provided, each fastening bolt passing through a mounting hole and screwed into a threaded hole.
[0008] Furthermore, the mounting hole is an elongated hole, and the mounting hole extends circumferentially along the screw base.
[0009] Furthermore, the screw base extends in a ring shape along the circumference of the utility pole, and the screw base is sleeved on the outside of the utility pole.
[0010] Furthermore, the screw base includes a first half-ring and a second half-ring disposed opposite to each other, the first half-ring being detachably connected to the second half-ring.
[0011] Furthermore, the opposing ends of the first half-ring and the second half-ring at least partially overlap, such that at least a portion of the mounting hole on the first half-ring aligns with the mounting hole on the second half-ring and communicates with the threaded hole.
[0012] Furthermore, a first stepped groove is formed on the inner side of the end of the first half-ring to mate with the end of the second half-ring, and a second stepped groove is formed on the outer side of the end of the second half-ring to mate with the end of the first half-ring.
[0013] Furthermore, the utility pole is provided with a ring-shaped mounting groove, the threaded hole is provided in the bottom wall of the mounting groove, the screw base is installed in the mounting groove, and the outer side of the screw base is flush with the opening of the mounting groove.
[0014] Furthermore, the first threaded portion includes a threaded post, and the second threaded portion includes a connecting hole disposed on the screw base, wherein the inner wall of the connecting hole is provided with an internal thread.
[0015] Furthermore, the screw base is integrally formed inside the utility pole, and the second threaded portion protrudes from the periphery of the utility pole.
[0016] In summary, this utility model has the following beneficial effects: 1. The safety attachment point structure of this utility model fixes the screw base to the utility pole by passing a fastening bolt through the mounting hole of the screw base and screwing it into the threaded hole of the utility pole. Then, the screw hook is fixed to the screw base through the cooperation of the first threaded part and the second threaded part. Thus, when working on the pole, the safety belt hook can be attached to the hanging ring of the screw hook, which facilitates the attachment of the safety belt on the utility pole and improves the safety of working on the pole. The safety belt attachment point can be set at a high position on the utility pole as needed to achieve high attachment and low use of the safety belt, ensuring safety during operation.
[0017] 2. The screw base has multiple mounting holes, and the utility pole has multiple threaded holes. The fastening bolts pass through the mounting holes and threaded holes one by one to fix the screw base to the utility pole, making the connection between the screw base and the utility pole more secure and reliable.
[0018] 3. The mounting hole is a long, narrow hole. Only a portion of the mounting hole needs to be aligned with the threaded hole to allow the fastening bolt to be inserted, which facilitates the connection between the screw base and the utility pole.
[0019] 4. The screw base extends circumferentially in a ring shape and is fitted over the utility pole, so that the stress of the screw base can be evenly distributed to the periphery of the utility pole, rather than just being held by the fastening bolts, thereby improving the strength of the connection between the screw base and the utility pole.
[0020] 5. The screw base includes a detachable first half-ring and a second half-ring, so that when installing the screw base, the first half-ring and the second half-ring can be separated first, and the first half-ring and the second half-ring can be put on from both sides of the utility pole respectively, and then the first half-ring and the second half-ring can be connected, which facilitates the installation of the screw base.
[0021] 6. The opposite ends of the first half ring and the second half ring overlap. The mounting holes of the overlapping part of the first half ring and the second half ring are aligned with each other and connected to the threaded hole. Thus, the fastening bolt can pass through the aligned mounting holes on the first half ring and the second half ring at the same time and be screwed into the threaded hole, realizing the connection between the first half ring and the second half ring and the utility pole, and also connecting the first half ring and the second half ring.
[0022] 7. The first half-ring and the second half-ring are respectively provided with a first step groove and a second step groove. The end of the first half-ring mates with the second step groove of the second half-ring, and the end of the second half-ring mates with the step groove of the first half-ring. This allows the first half-ring and the second half-ring to have the same inner diameter when their ends overlap, thus better fitting the utility pole.
[0023] 8. A ring-shaped mounting groove is set on the utility pole, and the screw base is installed in the mounting groove. The screw base can transfer the vertical stress to the inner wall of the mounting groove, reduce the shear force on the fastening bolt, and improve the strength of the safety hanging point structure.

Detailed Implementation
[0028] The present invention will be further described below with reference to the accompanying drawings.
[0029] This embodiment discloses a safety attachment point structure 1000 for a utility pole, referring to... Figure 1 The safety attachment point structure 1000 is set at a height of 100 on the utility pole to allow for the attachment of safety belts, enabling the safety belts to be used at a low height and improving the safety of working on the pole.
[0030] Reference Figure 1 and Figure 2 The safety attachment structure 1000 includes a screw base 200, a screw hook 300, and a fastening bolt 400. The screw hook 300 includes a first threaded portion 310 and a hanging ring 320, which is integrally connected to the first threaded portion 310 and is used for attaching a seatbelt. The screw base 200 has a second threaded portion 210 that screws into the first threaded portion 310. The screw base 200 and the screw hook 300 are threaded together to achieve a detachable connection.
[0031] In this embodiment, the first threaded portion 310 includes a threaded post, and the second threaded portion 210 includes a connecting hole disposed on the screw base 200, the inner wall of which is provided with an internal thread. When the screw hook 300 is connected to the screw base 200, the threaded post is screwed into the connecting hole. This makes the connection between the screw hook 300 and the screw base 200 firm and reliable, and facilitates the connection between the screw base 200 and the screw hook 300.
[0032] The hanging ring 320 is a metal ring-shaped component, and the hanging ring 320 is rotatably connected to the first threaded portion 310 so that the hanging ring 320 can rotate relative to the first threaded post to adjust the angle and adapt to the needs of the seat belt. Specifically, in this embodiment, the end of the first threaded portion 310 has a connector 330, and the connector 330 has a rotating hole 331. The hanging ring 320 passes through the rotating hole 331 to achieve a rotatable connection between the hanging ring 320 and the first threaded portion 310.
[0033] The utility pole 100 is provided with a threaded hole 110. The fastening bolt 400 passes through the screw base 200 and is screwed into the threaded hole 110 to fix the screw base 200 to the utility pole 100.
[0034] In this embodiment, the utility pole 100 is a cylindrical concrete component, and the screw base 200 is a metal casting. The screw base 200 is in the shape of an arc that fits against the utility pole 100, so that the connection between the screw base 200 and the utility pole 100 is firm and reliable, and the stress of the screw base 200 can be well transmitted to the utility pole 100.
[0035] Reference Figure 2 and Figure 3 In this embodiment, a ring-shaped mounting groove 120 is provided around the periphery of the utility pole 100, extending circumferentially along the utility pole 100. The screw base 200 is installed in the mounting groove 120. Thus, the screw base 200 can transfer vertical stress to the inner wall of the mounting groove 120, reducing the shear force borne by the fastening bolt 400 and improving the strength of the safety anchor structure 1000. The outer surface of the screw base 200 is flush with the opening of the mounting groove 120, allowing the screw base 200 to be recessed into the mounting groove 120, reducing the exposure of the screw base 200 and minimizing its impact on operations, while also improving the overall appearance of the utility pole 100.
[0036] In this design, the threaded hole 110 on the utility pole 100 is formed in the bottom wall of the mounting groove 120, and the screw base 200 has a mounting hole 220 that penetrates through the screw base 200. The mounting hole 220 is aligned and connected with the threaded hole 110, and the fastening bolt 400 passes through the mounting hole 220 and is screwed into the threaded hole 110, thereby fixing the screw base 200 in the mounting groove 120.
[0037] In other embodiments, the mounting groove 120 may be omitted, and the screw base 200 may be directly fixed to the outer periphery of the utility pole 100. In other embodiments, the screw base 200 may be integrally manufactured with the utility pole 100, i.e., the screw base 200 is embedded within the utility pole 100 during precast casting, with the second threaded portion 210 of the screw base 200 protruding from the utility pole 100 for connection by the first threaded portion 310 of the screw hook 300.
[0038] In this embodiment, the screw base 200 is provided with multiple mounting holes 220, and the utility pole 100 is provided with multiple threaded holes 110. The mounting holes 220 and threaded holes 110 correspond one-to-one (i.e., each mounting hole 220 is aligned with one threaded hole 110). Multiple fastening bolts 400 are provided, and the number of fastening bolts 400 is the same as the number of threaded holes 110. Each fastening bolt 400 passes through one mounting hole 220 and is screwed into one threaded hole 110, thereby enhancing the connection strength between the screw base 200 and the utility pole 100, making the connection between the screw base 200 and the utility pole 100 more secure and reliable.
[0039] In this embodiment, the mounting hole 220 is an elongated hole that extends circumferentially along the screw base 200. When the screw base 200 is installed on the utility pole 100, even if the tolerance between the utility pole 100 and the screw base 200 is large and it is difficult to fit completely, the mounting hole 220 only needs to be partially aligned with the threaded hole 110 to allow the fastening bolt 400 to pass through and be screwed into the threaded hole 110. This facilitates the connection between the screw base 200 and the utility pole 100 and reduces the machining accuracy requirements of the screw base 200.
[0040] In this embodiment, the screw base 200 extends in a ring shape along the circumference of the utility pole 100. The screw base 200 is fitted outside the mounting groove 120 on the utility pole 100, so that the stress of the screw base 200 can be evenly distributed to the periphery of the utility pole 100, rather than being held by the fastening bolt 400, thereby improving the strength of the connection between the screw base 200 and the utility pole 100.
[0041] In addition, in other embodiments, the screw base 200 may also be of a superior or inferior arc shape.
[0042] In this embodiment, the screw base 200 includes a first half-ring 230 and a second half-ring 240 disposed opposite to each other. The first half-ring 230 is detachably connected to the second half-ring 240, and the first half-ring 230 and the second half-ring 240 are spliced together to form a complete ring structure. When installing the screw base 200, the first half-ring 230 and the second half-ring 240 can be separated first, and the first half-ring 230 and the second half-ring 240 can be respectively fitted onto both sides of the utility pole 100, and then the first half-ring 230 and the second half-ring 240 can be connected, which facilitates the installation of the screw base 200.
[0043] In this embodiment, the opposite ends of the first half-ring 230 and the second half-ring 240 at least partially overlap, and the mounting holes 220 on at least part of the first half-ring 230 and the second half-ring 240 are aligned and connected to the threaded hole 110. Specifically, the mounting holes 220 on the overlapping portion of the first half-ring 230 and the second half-ring 240 are aligned with each other and connected to the threaded hole 110, so that the fastening bolt 400 can pass through the aligned mounting holes 220 on the first half-ring 230 and the second half-ring 240 and be screwed into the threaded hole 110, thereby realizing the connection between the first half-ring 230 and the second half-ring 240 and the utility pole 100, and also connecting the first half-ring 230 and the second half-ring 240. The connection between the first half-ring 230, the second half-ring 240 and the utility pole 100 is convenient and reliable.
[0044] The inner sides of both ends of the first semi-ring 230 are provided with first stepped grooves 231, and the outer sides of both ends of the second semi-ring 240 are provided with second stepped grooves 241. When the first semi-ring 230 and the second semi-ring 240 are connected, the first stepped grooves 231 and the second stepped grooves 241 engage, that is, the two ends of the first semi-ring 230 are respectively inserted into the two second stepped grooves 241, and the two ends of the second semi-ring 240 are respectively inserted into the two first stepped grooves 231. This allows the ends of the first semi-ring 230 and the second semi-ring 240 to overlap even when their inner diameters are the same, so that the screw base 200 can better fit the utility pole 100.
[0045] In other embodiments, the inner diameter of the first half-ring 230 may also be larger than the outer diameter of the second half-ring 240, so that the ends of the first half-ring 230 and the second half-ring 240 can overlap without the need to open the first step groove 231 and the second step groove 241.
[0046] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
