Description
Technical Field
[0001] This utility model relates to the field of building engineering safety protection technology, and in particular to a high-voltage line protection frame for building engineering. Background Technology
[0002] During construction, overhead high-voltage lines around the construction site pose a significant safety hazard. To prevent electric shock accidents caused by accidental contact or insufficient safety distance during operation of large machinery such as tower cranes and cranes, it is usually necessary to take effective physical isolation and protection measures for high-voltage lines in the vicinity of the construction area. Currently, the common practice is to wrap the high-voltage lines with insulated protective pipes or protective frames.
[0003] These protective frames are typically made up of multiple standard straight pipe sections spliced together to cover the entire dangerous line. In practical applications, the straight pipe sections of the protective frame are fixed together by connectors to form a continuous protective structure. This design can provide good protection for high-voltage lines running in a straight line, and the structure is simple and easy to implement.
[0004] However, the laying path of overhead high-voltage lines is not always straight. Often, due to terrain, building avoidance, or other planning needs, there are corners or bends. When existing straight pipe protective frames are applied to these angled line sections, their rigid structure, which only supports linear connections, exposes its inherent defects. At the corner, the two straight pipes cannot be connected to fit the actual route of the line, resulting in an open gap at the apex of the bend, exposing part of the high-voltage line. This leads to a loss of continuity and integrity of protection, leaving serious safety hazards. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a high-voltage line protection frame for building engineering, aiming to improve the technical problems of existing high-voltage line protection devices for building engineering being difficult to adapt to line corners and inconvenient to install.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-voltage line protection frame for construction engineering includes: a steel pipe and connecting rings; and an adjusting assembly connected between two connecting rings. The adjusting assembly includes a connecting post fixed to one connecting ring and a fixing ring fixed to the other connecting ring. The outer peripheral wall of the fixing ring is provided with a second locking tooth. The adjusting assembly also includes a sliding ring slidably sleeved on the outer wall of the connecting post, and a first locking tooth is fixedly connected to the sliding ring. A spring is sleeved on the connecting post. The two connecting rings are connected and combined through the adjusting assembly. The two ends of the spring abut against the root of the sliding ring and the connecting post, respectively. Under the elastic force of the spring, the first locking tooth and the second locking tooth engage.
[0007] Preferably, the high-voltage line protection frame for building engineering further includes an insulating heat shrink sleeve and a connecting assembly; the insulating heat shrink sleeve is fitted onto the outer wall of the steel pipe, and the connecting assembly is used to fix the insulating heat shrink sleeve to the steel pipe; the connecting assembly includes a fixing plate fixed to the outer wall of the insulating heat shrink sleeve, a fixing column connected to the fixing plate, and a conical locking block connected to the end of the fixing column; a through hole is opened on the wall of the steel pipe, and the conical locking block passes through the through hole and is engaged and fixed with an elastic plate disposed on the inner wall of the steel pipe.
[0008] Preferably, both the first and second locking teeth are serrated structures evenly distributed along the circumferential direction.
[0009] Preferably, the connecting ring is a ring structure consisting of two half-rings connected by fasteners.
[0010] Preferably, the elastic plate is a metal spring sheet that is inclined toward the axis of the steel pipe.
[0011] Preferably, one end of the fixing post passes through the fixing plate and is fixedly connected to it.
[0012] Preferably, the first locking tooth is integrally formed on the end face of the slip ring.
[0013] This utility model has the following beneficial effects: 1. In this utility model, by setting an adjustment component consisting of a slip ring, a spring and intermeshing teeth, the problem of the existing protective frame having a simple structure and being difficult to fit high-voltage lines with different directions is solved. This allows for arbitrary adjustment of the connection angle between adjacent steel pipes, improving the device's adaptability to complex lines and the continuity of protection.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Reference Figures 1-5 This utility model provides an embodiment of a high-voltage line protection frame for construction engineering, including a steel pipe 1 and a connecting ring 2 for connecting two sections of the steel pipe 1. The connecting ring 2 is an annular structure composed of two half-rings connected by fasteners, and is fastened to the outer wall of the steel pipe 1 through this structure. The core of this protection frame is that an adjustment component 4 is set between the two connecting rings 2. The angle between the two sections of the steel pipe 1 can be adjusted and locked through the adjustment component 4. Specifically, the adjustment component 4 includes a connecting column 401 and a fixing ring 404. One end of the connecting column 401 is fixed to one of the connecting rings 2, and the fixing ring 404 is fixed to the other connecting ring 2. The outer peripheral wall of the fixing ring 404 is provided with a second locking tooth 406. A sliding ring 403 is slidably sleeved on the outer wall of the connecting column 401. A first locking tooth 405 is fixedly connected to the end face of the sliding ring 403. The first locking tooth 405 is preferably integrally formed on the end face of the slip ring 403. The spring 402 is sleeved on the connecting post 401, and the two ends of the spring 402 abut against the root of the slip ring 403 and the connecting post 401, respectively. In the initial state, the spring 402 is in a naturally extended or pre-compressed state, and its elastic force pushes the slip ring 403, so that the first locking tooth 405 is fully engaged with the second locking tooth 406 on the outer peripheral wall of the fixed ring 404. At this time, the angle between the two connecting rings 2 is firmly locked. The first locking tooth 405 and the second locking tooth 406 are both serrated structures evenly distributed along the circumferential direction. This toothed engagement method provides extremely high connection reliability. When angle adjustment is required, along the connecting post 404, the first locking tooth 405 is fully engaged with the second locking tooth 406 on the outer peripheral wall of the fixed ring 404. The axial force applied to the connecting post 401 pushes the slip ring 403, which then slides against the elastic force of the spring 402, thereby compressing the spring 402. At the same time, it drives the first locking tooth 405 to move until the first locking tooth 405 and the second locking tooth 406 are completely disengaged. At this time, the two connecting rings 2 can rotate relative to each other, thereby driving the two fixed steel pipes 1 to form the required angle. After the angle is adjusted, the external force applied to the slip ring 403 is removed, and the compressed spring 402 rebounds, pushing the slip ring 403 to slide back along the connecting post 401 and reset. It then drives the first locking tooth 405 to engage with the second locking tooth 406 again, thereby firmly locking the new angle. The connecting component 5 includes a fixed plate 502 fixed to the outer wall of the insulating heat shrink sleeve 3, a fixed post 503 fixedly connected to the fixed plate 502, and a conical locking block 501 connected to the end of the fixed post 503; at the same time, a through hole is correspondingly opened on the wall of the steel pipe 1, and an elastic plate 504 is provided on the inner wall of the steel pipe 1 at the position corresponding to the through hole. When installing the insulating heat shrink sleeve 3, it is moved axially along the steel pipe 1 to the predetermined position, and then the fixing plate 502 is pushed so that the fixing column 503 drives the conical block 501 to pass through the through hole of the steel pipe 1. During the insertion process, the conical surface of the conical block 501 will first contact and expand the elastic plate 504. When the maximum diameter part of the conical block 501 has completely passed through the through hole, the expanded elastic plate 504 will quickly rebound due to its own elasticity and lock onto the tail step of the conical block 501, thereby firmly locking the entire connecting assembly 5 onto the steel pipe 1, thus completing the axial limiting and fixing of the insulating heat shrink sleeve 3. The elastic plate 504 is a metal spring sheet that is inclined towards the axis of the steel pipe 1. This inclined structure not only facilitates the smooth entry of the conical locking block 501, but also provides a stable and reliable locking force. The entire fixing process is convenient to operate and does not require any special tools, which greatly improves the on-site installation efficiency. To improve the reliability and accuracy of angle locking, please refer to... Figure 2 and Figure 4Both the first locking tooth 405 and the second locking tooth 406 are serrated structures evenly distributed along the circumference. This structure can provide multiple contact points during meshing, ensuring the stability of the connection and the effective transmission of torque. To further enhance the structural strength and concentricity, the first locking tooth 405 is preferably integrally formed on the end face of the slip ring 403. To facilitate the installation of the protective frame onto the steel pipe 1, the connecting ring 2 is specifically a ring structure composed of two half-rings connected by fasteners. During installation, the two half-rings are placed on both sides of the steel pipe 1, and then fastened with bolts or other fasteners to reliably fix the connecting ring 2 to the outer wall of the steel pipe 1. To ensure the snap-fit effect of the connecting component 5, the elastic plate 504 is specifically a metal spring sheet that is inclined towards the axis of the steel pipe 1; at the same time, to ensure the integrity of the connection, one end of the fixing post 503 passes through the fixing plate 502 and is fixedly connected to it. This fixed connection method can be welding or riveting.
[0019] In terms of structural layout, the slip ring 403 and the connecting post 401 are in a sliding fit, which allows the slip ring 403 to move along the axial direction of the connecting post 401 under the action of external force; the setting position of the spring 402 and the effective length of the connecting post 401 together ensure that the slip ring 403 has sufficient stroke, so that the first locking tooth 405 can move to a position completely separated from the second locking tooth 406.
[0020] Working principle: When adjusting the angle, the operator pushes the slip ring 403 along the axial direction of the connecting column 401. After being subjected to force, the slip ring 403 slides and compresses the spring 402, while simultaneously causing the first locking tooth 405 fixed on its end face to separate from the second locking tooth 406 on the outer peripheral wall of the fixed ring 404. When the first locking tooth 405 and the second locking tooth 406 are completely disengaged, the two connecting rings 2 can rotate freely, thereby adjusting the included angle between the two steel pipe sections 1 to adapt to the direction of the high-voltage line. After the angle is adjusted to the predetermined position, the external force applied to the slip ring 403 is released, the compressed spring 402 rebounds and resets, pushing the slip ring 403 to move in the opposite direction until the first locking tooth 405 re-engages with the second locking tooth 406 at the new angle position and locks in place. Through the tooth-shaped meshing structure of the first locking tooth 405 and the second locking tooth 406, this utility model solves the problem that existing protective devices are difficult to adapt to line turning angles, ensuring the reliability of the connection. When fixing the insulating heat shrink sleeve 3, it is placed on the predetermined position of the steel pipe 1. Then, the conical locking block 501 of the connecting component 5 is aligned with the through hole on the wall of the steel pipe 1 and pushed in. During the process of the conical locking block 501 entering the through hole, its conical guide surface will force the elastic plate 504 on the inner wall of the steel pipe 1 to undergo elastic deformation. When the conical locking block 501 completely passes through the through hole, the elastic plate 504 immediately rebounds and locks at the tail of the conical locking block 501, thereby preventing the conical locking block 501 from exiting. Since the fixing plate 502 is always located on the outside of the insulating heat shrink sleeve 3, through the quick locking and engagement of the conical locking block 501 and the elastic plate 504, this utility model realizes the quick and tool-free fixing of the insulating heat shrink sleeve 3, solving the problems of complex installation and fixing structure and low efficiency in the prior art.
