Description

Technical Field

[0001] This utility model relates to the field of subway safety protection, specifically to a safety protection device for subway electromechanical installation. Background Technology

[0002] Safety barriers are crucial safety facilities in subway electromechanical installation. Their main function is to demarcate work areas and prevent personnel from accidentally entering dangerous zones, thereby ensuring the safety of construction workers and equipment. The installation of safety barriers as an isolation and protection measure is particularly important in areas involving high-altitude operations, around electrical equipment, or near mechanical equipment. By installing these barriers, the likelihood of accidents can be significantly reduced, ensuring the smooth and safe operation of the construction process and subway system.

[0003] Utility model patent CN215564974U discloses a novel electromechanical installation safety protection device. This device consists of guardrail A and guardrail B, with guardrail A located to the left of guardrail B and the two fixedly connected via a rotary connector. Two innovative stabilizing devices are added to the bottom of the guardrail. These stabilizing devices effectively reinforce the guardrail placed on the ground, ensuring it remains firmly in its predetermined position during use and fulfills its protective function. Specifically, when the stabilizing devices are rotated to a cross angle with the fixed crossarm, they provide support on both the front and rear bottom sides of the guardrail, working in conjunction with the guardrail's original two mounting feet to provide support at multiple angles at the bottom of the guardrail, significantly enhancing the stability of the entire electromechanical installation safety protection device.

[0004] Nevertheless, the aforementioned published patents regarding novel electromechanical installation safety protection devices primarily focus on improving their placement stability, neglecting the technical requirement of providing lighting at the installation site. Performing electromechanical installation work in low-light environments such as subway construction often leads to obstructed vision, adversely affecting workers' accuracy and efficiency. Low-light environments not only increase the probability of misoperation and accidents but may also prolong the construction period, threatening the overall construction progress and quality. Therefore, developing a safety protection device specifically designed for subway electromechanical installation with integrated lighting functionality is particularly important.

Detailed Implementation

[0033] The technical solution of this utility model is described in further detail below with reference to the accompanying drawings, but the scope of protection of this utility model is not limited to the following description.

[0034] In the following sections, embodiments of the present disclosure will be described in detail with the aid of the accompanying drawings. However, it should be understood that the present disclosure is not limited to the specific forms shown herein. Rather, it should be understood to encompass various variations, equivalents, and / or alternatives to the embodiments of the present disclosure. In illustrating the drawings, the same reference numerals will be used to denote similar components.

[0035] It should be clarified that while the following description provides detailed specific information to aid in a comprehensive understanding of the exemplary embodiments, those skilled in the art will recognize that the exemplary embodiments can be implemented even without these specific details. For example, the system may be illustrated using block diagrams to avoid excessive detail that could obscure the clarity of the example. In other cases, to maintain the clarity of the example, unnecessary details of well-known processes, structures, and techniques may be omitted.

[0036] like Figure 1 and Figure 2 As shown, a safety protection device for subway electromechanical installation includes a guardrail 1 and a grid mesh 2 fixedly installed inside the guardrail 1. The guardrail 1 includes at least two horizontal bars and several vertical bars, and the horizontal bars and vertical bars are connected to form a frame for installing the grid mesh.

[0037] The ends of the horizontal bars are provided with connecting components for splicing. Adjacent horizontal bars of different guardrails 1 are connected by connecting components. The grid includes several rhomboid or rectangular units, which are located within the frame formed by the horizontal bars and vertical bars.

[0038] The guardrail 1 is provided with a guide component, and the guide component is provided with a slide groove 7. A guide rod 8 is fixedly installed in the slide groove 7. A sliding block 10 is also provided in the slide groove 7. The sliding block 10 is provided with a through hole 11, and the through hole 11 cooperates with the guide rod 8. The sliding block 10 is used to install a lighting lamp 14. The lighting lamp 14 is connected to the sliding block 10 through a connecting mechanism, and the connecting mechanism is used to adjust the illumination angle of the lighting lamp 14.

[0039] When installing subway electromechanical equipment, a safety protection device is used to isolate and protect the installation site. After placing the guardrail 1 at the installation site, multiple sets of guardrail 1 are spliced ​​together through connecting components. The guardrail 1 can isolate and protect the subway electromechanical installation site. When installing electromechanical equipment at the subway installation site, the lighting at the installation site is usually not very good. The lighting lamp 14 can be controlled to produce light to illuminate the installation site. At the same time, the lighting lamp 14 can also illuminate the ground to prevent people from walking and accidentally colliding. This utility model can continuously illuminate the installation site, assist the workers in installing subway electromechanical equipment, and improve work efficiency and construction safety.

[0040] In a preferred embodiment, the rhomboid or rectangular unit is composed of several interlaced steel or iron wires, enhancing the overall stability and load-bearing capacity. The interlaced steel or iron wires form multiple triangular support structures, which possess excellent mechanical stability and can withstand significant pressure and tension, thereby improving the overall load-bearing capacity of the structure.

[0041] In a preferred embodiment, the crossbars and vertical bars connected to form a rectangular frame for mounting the grid. The rectangular frame, with its four sides supporting each other, creates a stable geometric structure. This structure effectively disperses and resists pressure when subjected to external forces, thereby enhancing the stability of the entire grid. The tight connection between the crossbars and vertical bars further ensures the frame's stability, allowing it to maintain a stable shape in various environments.

[0042] In a preferred embodiment, the guide component is a rectangular rod (with a rectangular cross-section) with a groove 7. End plates are provided at both ends of the rectangular rod, and the two ends of the guide rod 8 are fixed to the end plates at both ends of the rectangular rod. The guide component is designed as a rectangular rod with a groove 7, and its cross-section is rectangular, ensuring structural stability and guiding accuracy. The cleverly placed end plates at both ends of the rectangular rod not only enhance the overall structural robustness but also effectively prevent guiding failure caused by excessively large openings at both ends of the groove 7. The two ends of the guide rod 8 are securely connected to the end plates at both ends of the rectangular rod, ensuring that the guide rod 8 remains stable during sliding and is not prone to deviation or wobbling.

[0043] In a preferred embodiment, see Figure 3 The connecting mechanism includes a limiting ring 12, a rotating ball 13 and a connecting rod. The connecting rod is disposed between the rotating ball 13 and the lighting lamp 14. One end of the connecting rod is fixed to the rotating ball 13, and the other end of the connecting rod is fixed to the back of the lighting lamp 14.

[0044] The limiting ring 12 includes a threaded part and a retaining ring part. The threaded part is provided with an internal thread, and the retaining ring part is located next to the threaded part and fixed to the threaded part. During use, the connecting rod passes through the threaded part and the retaining ring part in sequence, and the rotating ball 13 is blocked by the retaining ring part to prevent the rotating ball 13 from sliding out of the limiting ring 12. Under normal circumstances, the threaded part has a through space, and the retaining ring part is at the end of the through space, which will block the edge of the through space to prevent the rotating ball 13 from sliding out.

[0045] A connecting post is provided on the side of the sliding block 10, and the connecting post has external threads. The connecting post and the sliding block 10 constitute a mounting body, which has a groove (or arc-shaped groove, such as a semi-circular groove) that mates with the rotating ball 13. During use, a portion of the rotating ball 13 is located within the groove. The lighting lamp 14 can drive the rotating ball 13 to rotate on the limiting ring 12. After adjusting the lighting lamp 14 to a predetermined angle, the limiting ring 12 is tightened to fix the angle of the lighting lamp 14. Preferably, an arc-shaped portion that mates with the rotating ball 13 is also provided on the retaining ring portion to increase the contact area between the retaining ring portion and the rotating ball 13. The mating of the rotating ball 13 with the limiting ring 12 facilitates fixing the rotating ball 13 and limits the position of the lighting lamp 14.

[0046] In a preferred embodiment, a magnetic strip 9 is provided on the guide component, and a magnetically attracted part (such as an iron part) is provided on the sliding block 10. The magnetically attracted part cooperates with the magnetic strip 9, and when the sliding block 10 is stationary, the magnetic strip 9 limits the sliding block 10. The magnetic strip 9 on the guide component and the magnetically attracted part on the sliding block 10 cooperate with each other, realizing that the magnetic strip 9 can effectively limit the sliding block 10 when it is stationary. The cooperation between the magnetic strip 9 and the magnetically attracted part enhances the stability of the sliding block 10 in the stationary state, effectively preventing slippage or displacement caused by external factors, thereby improving the reliability and safety of the overall structure.

[0047] In a preferred embodiment, see Figure 4 The sliding block 10 has a mounting groove 15 inside, and a battery assembly 16 is disposed inside the mounting groove 15. The battery assembly 16 is electrically connected to the lighting lamp 14. Normally, the battery assembly 16 is connected to the lighting lamp 14 via a wire, which passes through the sliding block 10 and connects to the lighting lamp 14. For higher requirements, the wire can pass through the rotating ball 13 and the connecting rod to connect to the lighting lamp 14, allowing for concealed installation. Using the battery assembly 16 is also suitable for the construction environment.

[0048] In a preferred embodiment, a cover plate 17 with a mounting groove 15 is provided on the sliding block 10, and the cover plate 17 is fixedly connected to the sliding block 10 (e.g., by screws). The fixed connection between the cover plate 17 and the sliding block 10 ensures that the cover plate 17 will not loosen or fall off during use, further enhancing the stability of the structure.

[0049] In a preferred embodiment, the connecting assembly includes a male connector and a female connector, which are respectively disposed at both ends of the crossbar;

[0050] The male connector protrudes from the outermost vertical rod of the frame on which the grid is installed, and the male connector is provided with a positioning hole 4;

[0051] The female connector includes a connecting frame 5 and a limiting hole 6. The connecting frame 5 is I-shaped. One end of the connecting frame 5 is rotatably connected to the crossbar. The other end of the connecting frame 5 includes an upper connecting plate and a lower connecting plate. Both the upper and lower connecting plates are provided with limiting holes 6. The positioning hole 4 is configured to cooperate with the limiting hole 6. In use, the male connector of one guardrail 1 extends into the female connector of another guardrail 1. The male connector is located between the upper and lower connecting plates and is connected to the female connector by a bolt assembly.

[0052] The guardrail 1 is spliced ​​together with connecting components to separate and protect the subway electromechanical installation site. Positioning pins or bolts are used to pass through positioning holes 4 and limiting holes 6 to splice adjacent guardrails 1. The guardrail 1 can be adjusted in angle, so it is easy to adapt to different terrains and improve the flexibility of the safety protection device for subway electromechanical installation.

[0053] In a preferred embodiment, support legs 3 are fixedly installed at the bottom of the guardrail 1, with at least a 1-meter gap between two adjacent support legs 3. By ensuring a gap of at least 1 meter between two adjacent support legs 3, the load borne by the guardrail 1 can be effectively distributed, avoiding structural instability caused by excessive local stress and improving safety. The wider spacing between the support legs 3 means that a more spacious space is formed inside the guardrail 1, reducing the risk of accidental collisions between people or objects and the support legs 3. At the same time, this design also makes it easier for people to move around inside the guardrail 1, improving the overall safety of use.

[0054] In a preferred embodiment, a communication unit is also provided inside or beside the sliding block 10. This communication unit is connected to and powered by the battery assembly 16. The communication power supply is connected to the battery management module of the battery assembly 16 and is responsible for uploading battery power information to the control center. The close connection between the communication unit and the battery assembly 16 ensures a stable power supply. The communication unit not only communicates with the battery assembly 16 but also establishes a direct connection bridge with the battery management module, enabling real-time uploading of battery power information to the control center. Overall, this embodiment achieves real-time monitoring and uploading of battery power, providing data support to the control center and allowing timely monitoring of the battery's usage status.

[0055] This utility model relates to a subway electromechanical installation safety protection device, which achieves flexible deployment through modular splicing of the guardrail 1: a rectangular frame composed of horizontal and vertical bars is embedded with a grid mesh 2 having a triangular support structure, and multi-angle splicing is achieved through the hinged connection of male and female heads; the spaced arrangement of the bottom support legs 3 enhances structural stability. In the guide component, the rectangular rod and guide rod 8 form a precise slide, and the sliding block 10 is fixed in multiple positions through magnetic attraction; its internal battery assembly 16 powers the mounted lighting lamp 14, and three-dimensional angle adjustment is achieved through the rotating ball 13-limiting ring 12 mechanism. The communication unit can transmit the battery status back to the control center, forming a complete intelligent lighting system. The components work together to create a safe working area through physical isolation and improve the construction environment through the adaptive lighting system, ultimately achieving a dual improvement in construction efficiency and safety.
