DETAILED DESCRIPTION

[0029] In order to make those skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0030] The cable well inner safety operation platform provided by the embodiment of the application can solve the problem that the insulation pad cannot play a safe protection role in the case of deep water accumulation.

[0031] As shown in Figure 1 and Figure 2 , the cable well inner safety operation platform provided by the embodiment of the application comprises a bottom frame 1, a through hole 11 is formed in the top surface of the bottom frame 1, a plurality of parallel support bars 2 are fixed in the through hole 11, and a bottom plate 3 is arranged on the top surfaces of the plurality of support bars 2; two hanging plates 4 are correspondingly arranged at the two ends of the bottom frame 1 and are hingedly connected to the corresponding ends of the hanging plates 4, the hanging plates 4 can be rotated to cover the top surface of the bottom frame 1, and the ends of the hanging plates 4 away from the bottom frame 1 are used to be lapped on the top surface of the cable well.

[0032] In the embodiment, the platform is provided with the bottom frame 1, the through hole 11 is formed in the top surface of the bottom frame 1, and a plurality of parallel support bars 2 are fixed in the through hole 11, the support bars 2 stably support the bottom plate 3 arranged above, and form a light and stable operation base. Through the design, the platform realizes the lightweight structure and the optimized balance of the bearing capacity. In addition, the platform is also provided with two hanging plates 4, which are hingedly connected to the two ends of the bottom frame 1, can be flexibly rotated and cover the top surface of the bottom frame 1. When operation is needed, the hanging plates 4 can be unfolded and lapped on the top surface of the cable well to provide a safe and stable foothold for the construction personnel. This design not only facilitates the quick installation and disassembly of the platform, but also greatly improves the convenience of carrying and carrying. In actual application, the construction personnel only need to simply operate to hang the hanging plates 4 on the side wall of the cable well, and then stand or squat on the bottom plate 3 to perform the suspended operation, which significantly improves the operation safety. At the same time, since the support bars 2 are embedded in the through hole 11, the bottom plate 3 is stably supported, which further ensures the stability and reliability of the platform. The platform realizes the lightweight design, is convenient to carry and assemble, and provides an ideal solution for the cable well operation.

[0033] In one embodiment, as shown in Figure 2 and Figure 3 , the cable well inner safety operation platform comprises two parallel side plates 5, the two side plates 5 are detachably connected to the bottom frame 1 and are arranged between the two hanging plates 4, and an operation chamber 6 is formed between the two side plates 5 and the two hanging plates 4.

[0034] In this embodiment, two side plates 5 are introduced in the design of the cable shaft safety work platform. These two side plates are ingeniously designed to be detachably connected to the bottom frame 1, and they are placed between the two hanging plates 4. Through the cooperation of the side plates 5 and the hanging plates 4, a relatively closed work chamber 6 is formed. This chamber provides a safer and more stable working environment for the workers. The establishment of the work chamber 6 effectively isolates other potential dangers in the cable shaft, such as falling debris, unstable walls, etc., thereby greatly enhancing the safety of the workers. The relatively closed working environment can reduce external interference, allowing workers to focus more on their work, thereby improving work efficiency. Since the side plates 5 are detachably connected, the entire work platform can be flexibly adjusted according to different cable shaft sizes and work requirements, enhancing the adaptability and practicality of the platform. The detachable design of the side plates also facilitates the carrying and assembly of the platform, making the entire work platform more convenient during transportation and storage, while also reducing transportation costs. Through the technical means of adding side plates 5 and forming a work chamber 6, the cable shaft safety work platform has been significantly improved in safety, work efficiency, adaptability, and portability.

[0035] In one embodiment, as shown in Figure 2 and Figure 3 two positioning plates 13 are fixed on the bottom frame 1, and the two positioning plates 13 are spaced apart to form a positioning channel 14. The side plate 5 is fixed with an insertion plate 52, which is inserted into the positioning channel 14.

[0036] In this embodiment, in the design of the cable shaft safety work platform, in order to further enhance the connection stability and convenience between the side plate 5 and the bottom frame 1, two positioning plates 13 are fixed on the bottom frame 1, and the two positioning plates 13 are spaced apart to form a positioning channel 14. This positioning channel 14 provides precise guidance and positioning for the installation of the side plate 5. An insertion plate 52 is fixed on the side plate 5, which is designed to be inserted into the positioning channel 14. Through the cooperation of the insertion plate 52 and the positioning channel 14, the quick and stable connection between the side plate 5 and the bottom frame 1 is achieved. The insertion of the insertion plate 52 and the positioning channel 14 makes the connection between the side plate 5 and the bottom frame 1 more stable, which can effectively resist various external forces and vibrations during work, ensuring the overall stability of the work platform. The design of the positioning plate 13 and the positioning channel 14 provides precise guidance and positioning for the installation of the side plate 5, ensuring the positional accuracy of the side plate 5 during installation, thereby ensuring the consistency of the shape and size of the work chamber 6. The insertion type connection makes the installation and disassembly of the side plate 5 more simple and fast, without the need for complex tools and steps, greatly saving installation time and labor cost.

[0037] In one embodiment, as shown inFigure 2 and Figure 3 As shown, each of the two side plates 5 is fixed with a positioning block 51 facing each other on one side, and the positioning block 51 has a positioning groove; each of the two hanging plates 4 is fixed with a positioning pin 45 facing each other on one side. When the positioning block 51 is engaged with the positioning pin 45 through the positioning groove, the side plate 5 is limited and fixed between the two hanging plates 4.

[0038] In this embodiment, positioning blocks 51 are fixed on the facing sides of the two side plates 5, and positioning grooves are formed on the positioning blocks 51. These positioning grooves provide precise insertion space for the positioning pins 45. Positioning pins 45 are fixed on the facing sides of the two hanging plates 4. These positioning pins 45 are designed to engage with the positioning grooves of the positioning blocks 51, thereby achieving precise positioning and fixation between the side plates 5 and the hanging plates 4.

[0039] The precise positioning between the side plate 5 and the hanging plate 4 is achieved through the snap-fit ​​engagement of the positioning groove on the positioning block 51 and the positioning pin 45. This positioning method not only ensures the consistency of the shape and size of the working chamber 6, but also improves the stability and safety of the entire working platform. The combined use of the positioning block 51 and the positioning pin 45 allows the side plate 5 to be firmly fixed between the hanging plates 4 during operation, effectively resisting various external forces and vibrations during operation, and ensuring the overall stability of the working platform. The design of the positioning block 51 and the positioning pin 45 makes the installation and removal of the side plate 5 and the hanging plate 4 simpler and faster. Simply align the positioning groove with the positioning pin 45 and insert it to achieve rapid positioning of the side plate 5, greatly saving installation time and labor costs. Because the combined use of the positioning block 51 and the positioning pin 45 provides a reliable positioning mechanism, the entire working platform can maintain stable performance during long-term use, improving the platform's reliability and durability.

[0040] In one embodiment, the side plate 5 is made of an insulating material.

[0041] In this embodiment, the side plate 5 is made of insulating material. The insulating material of the side plate 5 effectively isolates current, preventing electric shock accidents during operation in the cable well and significantly improving the safety of the operation. Various insulating materials can be selected for the side plate 5 to meet different performance and application requirements. Commonly used insulating materials include: glass fiber reinforced plastic, which has good insulation, flame retardant, and corrosion resistance properties and is widely used in power, communications, and other fields; epoxy glass cloth laminate, which has excellent heat resistance, insulation, and mechanical strength, making it an ideal material for manufacturing medium- to high-end electrical equipment; and polystyrene foam board, which has low density, high strength, and good insulation properties, suitable for building insulation and underground pipeline insulation.

[0042] In one implementation, such as Figure 2As shown, the base plate 3 includes two panels 31. Each of the two panels 31 has a serrated groove 32 on one side that is close to each other, and the two panels 31 are engaged with each other through the two serrated grooves 32.

[0043] In this embodiment, the serrated groove 32 design makes the connection between the panels 31 simple and quick. During installation, simply align and engage the serrated grooves 32 of the two panels 31 to easily assemble the base plate 3. Similarly, when disassembly is required, simply separate the panels 31, greatly improving work efficiency. Since the base plate 3 is composed of two panels 31, the length or width of the base plate can be adjusted according to actual needs. This design allows the base plate 3 to flexibly adapt to cable wells or work spaces of different sizes, improving the versatility and adaptability of the work platform. The engaging structure of the serrated groove 32 creates a tight connection between the two panels 31. This connection method not only improves the stability of the base plate but also effectively resists various external forces and vibrations during operation, ensuring the overall stability of the work platform. The panel design simplifies the production process, reduces material waste, and effectively controls costs. At the same time, since the base plate 3 can be disassembled and reused, the long-term cost is also reduced.

[0044] In one implementation, such as Figure 1 and Figure 2 As shown, the hanging plate 4 includes: a first plate 41, one end of which is hinged to the bottom frame 1; a second plate 42, one end of which is spaced apart from and fixed to the other end of the first plate 41, and the other end of the second plate 42 extends to a third plate 43, which is perpendicular to the second plate 42.

[0045] In this embodiment, the mounting plate 4 is carefully designed to include three main parts: a first plate 41, a second plate 42, and a third plate 43. One end of the first plate 41 is cleverly hinged to the base frame 1. This design allows the mounting plate 4 to rotate or fold relative to the base frame 1, thereby meeting different operational needs or saving space. One end of the second plate 42 is fixedly connected to the other end of the first plate 41 at a certain distance. This spacing design not only enhances the structural stability of the mounting plate 4 but also provides additional space for mounting or supporting other equipment. The third plate 43, as an extension of the mounting plate 4, extends vertically from the other end of the second plate 42. This vertical design not only makes the mounting plate 4 structurally more stable but also provides additional mounting points or support surfaces to meet more complex operational needs. Due to the hinged design between the first plate 41 and the base frame 1, the mounting plate 4 can be easily rotated or folded, thereby adapting to different operational scenarios or saving storage space. The spacing between the second plate 42 and the first plate 41, as well as the vertical extension of the third plate 43, significantly enhance the overall structural stability of the mounting plate 4. This design enables the mounting plate 4 to maintain a stable shape and performance when subjected to large loads or external impacts.

[0046] In one embodiment, a connecting rod is provided between the other end of the first plate 41 and one end of the second plate 42. One end of the connecting rod is threaded to the side of the other end of the first plate 41 via a first fixing bolt, and the other end of the connecting rod is threaded to the side of the second plate 42 via a second fixing bolt.

[0047] In this embodiment, a connecting rod is provided between the other end of the first plate 41 and one end of the second plate 42. This connecting rod plays a crucial connecting and supporting role. One end of it is tightly connected to the side of the other end of the first plate 41 by a first fixing bolt, while the other end is firmly connected to the side of the second plate 42 by a second fixing bolt. As a key component connecting the first plate 41 and the second plate 42, the connecting rod must have sufficient strength and rigidity to ensure that the hanging plate 4 remains stable under load. The first fixing bolt and the second fixing bolt are used to fix the two ends of the connecting rod to the first plate 41 and the second plate 42, respectively. Bolted connections have advantages such as simple structure, reliable connection, and easy disassembly and replacement. The setting of the connecting rod significantly enhances the structural stability of the hanging plate 4. Like a bridge, it tightly connects the first plate 41 and the second plate 42 together, making the entire hanging plate 4 more stable under load. Due to the supporting role of the connecting rod, the load-bearing capacity of the hanging plate 4 is significantly improved. This allows the hanging plate 4 to hang or support heavier equipment or tools, meeting more complex operational needs. The use of bolted connections makes the connection between the connecting rod and the first plate 41 and the second plate 42 simple and reliable. When it is necessary to disassemble or replace the hanging plate 4, simply loosening the bolts is sufficient, greatly improving work efficiency. By adjusting the length or position of the connecting rod, the shape and size of the hanging plate 4 can be flexibly adjusted to better adapt to different operating scenarios or needs.

[0048] In one implementation, such as Figure 1 and Figure 2 As shown, a cloth strip 44 is provided between the other end of the first plate 41 and the first end of the second plate 42. One end of the cloth strip 44 is fixed to the side of the other end of the first plate 41, and the other end of the cloth strip 44 is fixed to the side of the first plate 42.

[0049] In this embodiment, one end of the cloth strip 44 is firmly fixed to the other side of the first plate 41, while the other end is similarly and stably fixed to the other side of the second plate 42. This connection method is not only simple and quick, but also effectively connects the first plate 41 and the second plate 42 into a whole, enhancing the structural stability and load-bearing capacity of the hanging plate 4. The cloth strip 44, as a connecting material, is lightweight, flexible, and durable, adaptable to various complex environments and operational needs, providing a reliable guarantee for the connection of the hanging plate 4. To ensure a more thorough folding of the first plate 41 and the second plate 42, the cloth strip 44 is used to connect them, ensuring that they can be folded together.

[0050] In one embodiment, the mounting plate 4 and the bottom frame 1 are made of insulating material.

[0051] In this embodiment, the mounting plate 4 and the bottom frame 1 are made of insulating material. The insulating material of the mounting plate 4 and the bottom frame 1 effectively isolates current, preventing electric shock accidents during operation in the cable well and significantly improving the safety of the operation. Various insulating materials can be selected for the mounting plate 4 and the bottom frame 1 to meet different performance and application requirements. Commonly used insulating materials include: glass fiber reinforced plastic, which has good insulation, flame retardant, and corrosion resistance properties and is widely used in power, communications, and other fields; epoxy glass cloth laminate, which has excellent heat resistance, insulation, and mechanical strength, making it an ideal material for manufacturing medium- to high-end electrical equipment; and polystyrene foam board, which has low density, high strength, and good insulation properties, suitable for building insulation and underground pipeline insulation.
