Description

Technical Field

[0001] This utility model relates to the field of subway construction technology, specifically a safety belt auxiliary fixing device for elevated subway sections. Background Technology

[0002] In the traditional construction of elevated sections for subway power supply, concrete retaining walls at least 1.2 meters high are typically installed on both sides of the elevated bridge to ensure the safety of construction workers. This design ensures that construction workers are effectively protected when working near the bridge edge, thus avoiding the risk of accidental falls. However, because subway projects involve the collaborative work of multiple disciplines and the schedules of each discipline differ, the power supply discipline sometimes has to start construction before other infrastructure is fully installed. In particular, before the concrete retaining walls on both sides of the elevated bridge are installed, the power supply discipline must begin working at height near the edge. At this time, due to the lack of sufficient and secure suspension points to fix the safety belt hooks, construction workers face significant safety hazards when performing their tasks, greatly increasing the risk of working at height. To address these issues, there is an urgent need for a safety belt auxiliary fixing device for subway elevated section construction. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-5 In this embodiment of the invention, a safety belt auxiliary fixing device for elevated sections of subways includes a first clamp 2 and a second clamp 3 arranged opposite to each other. The first clamp 2 and the second clamp 3 are specifically bendable steel plates. The ends of the first clamp 2 and the second clamp 3 are connected by a connector 1, which is a pin. The pin passes through the first clamp 2 and the second clamp 3. Both the first clamp 2 and the second clamp 3 can rotate around the outer circumference of the pin, allowing free control of the other ends of the first clamp 2 and the second clamp 3 to achieve different degrees of opening and closing. Construction workers can quickly slip the clamps onto the side of the bolt without completely disassembling the nut, simplifying the installation process and improving the assembly efficiency of the safety belt auxiliary fixing device on the construction site. This is achieved by slipping the first clamp 2 and the second clamp 3 onto the bolts pre-embedded on the construction site, and then using the nut... The first clamp 2 and the second clamp 3 are firmly fixed to the bolts. The ends of the first clamp 2 and the second clamp 3 away from the connector 1 are respectively equipped with a first connecting plate 4 and a second connecting plate 5. The ends of the first connecting plate 4 and the second connecting plate 5 away from the connector 1 are provided with seat belt hook holes 6. The first connecting plate 4 and the second connecting plate 5 are connected by a locking component. The design of the first connecting plate 4 and the second connecting plate 5 can provide support points for the locking component. Under the action of the first connecting plate 4, the second connecting plate 5 and the locking component, the opening and closing ends of the first clamp 2 and the second clamp 3 can be closed and fixed. In addition, when the first connecting plate 4 and the second connecting plate 5 are closed, the seat belt hook holes 6 on them overlap, which facilitates the smooth passage of the seat belt hook and provides a firm suspension point for the seat belt hook.

[0021] Please see Figure 1-2In one embodiment, preferably, the locking component includes a pin structure 13 and a positioning structure. The pin structure 13 and the positioning structure are respectively mounted on the first connecting plate 4 and the second connecting plate 5. The pin structure 13 has a flexible installation method; it can be mounted on either the first connecting plate 4 or the second connecting plate 5. However, to ensure the normal operation of the system, the positioning structure is not mounted on the same connecting plate as the pin structure. This means that if the pin structure 13 is mounted on the first connecting plate 4, the positioning structure must be mounted on the second connecting plate 5; conversely, if the pin structure 13 is mounted on the second connecting plate 5, the positioning structure should be mounted on the first connecting plate 4. This design ensures that the positioning structure works in conjunction with the pin structure regardless of whether it is mounted on the first connecting plate 4 or the second connecting plate 5, achieving a stable connection between the two connecting plates. It also improves the flexibility and convenience of the assembly process. This arrangement ensures both construction efficiency and the safety of the construction site.

[0022] Please see Figure 2-3 In one embodiment, preferably, the positioning structure includes a fixed platform 7 mounted on the second connecting plate 5. A spring 8 is installed inside the fixed platform 7, and a positioning pin 9 that slides along the inner cavity of the fixed platform 7 is installed at the end of the spring 8. A slide rail 10 that passes through the inner cavity is opened on the surface of the fixed platform 7. A handle 11 located in the slide rail 10 is installed on the positioning pin 9. In designing the safety fixing device, the combined use of the slide rail 10 and the handle 11 plays multiple roles. First, the design of the slide rail 10 and the handle 11 ensures that the positioning pin 9 will not easily detach from the inside of the fixed platform 7, thereby reducing potential safety risks and improving the overall safety of the equipment. It also reduces safety accidents caused by accidental detachment of parts. In addition, the slide rail 10 limits the range of movement of the handle 11, which ensures precise control during operation. At the same time, the presence of the handle 11 provides a convenient manual adjustment point for construction personnel, allowing them to easily adjust the position of the positioning pin 9.

[0023] Please see Figure 4 In one embodiment, preferably, the second connecting plate 5 has a through hole 12, the inner diameter of which is larger than the outer diameter of the pin body 131. This way, when the first connecting plate 4 and the second connecting plate 5 are separated, the through hole 12 can provide a certain amount of movement for the pin body 131, ensuring that the first connecting plate 4 and the second connecting plate 5 are not affected by the pin body 131 when they are separated.

[0024] Please see Figure 5In one embodiment, preferably, the pin structure 13 includes a pin body 131. A first limiting piece 132 and a second limiting piece 133 are installed at the end of the pin body 131. The first limiting piece 132 and the second limiting piece 133 are respectively located on both sides of the first connecting plate 4. A through hole 134 adapted to the end of the positioning pin 9 is provided on the pin body 131. When the first connecting plate 4 and the second connecting plate 5 are combined, the through hole 134 on the pin body 131 and the position of the positioning pin 9 will be precisely aligned. In this case, due to the force of the spring 8, the positioning pin 9 can pass smoothly through the through hole 134, thereby achieving a stable and accurate positioning effect. When the positioning pin 9 is pressed to the bottom, the positioning pin 9 disengages from the through hole 134. At this time, the safety belt auxiliary fixing device on the bolt can be removed.

[0025] The working principle and usage process of this utility model are as follows: First, pre-embed bolts of the corresponding type at the construction site. Then, open the first clamp 2 and the second clamp 3 to the maximum and put them on the bolts. Next, merge the first connecting plate 4 and the second connecting plate 5. At this time, by pressing the positioning pin 9, the end of the pin body 131 can pass smoothly through the first connecting plate 4 and the second connecting plate 5. After the first connecting plate 4 and the second connecting plate 5 are merged, release the positioning pin 9. Under the action of the spring 8, the positioning pin 9 pops out and enters the through hole 134 to complete the fixation of the auxiliary fixing device. Then, rotate the nut on the bolt to achieve further locking. After locking, the construction personnel can hang the safety belt hook in the safety belt hook hole 6.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
