Description

Technical Field

[0001] This utility model relates to the field of insulated ladder technology, and specifically discloses an insulated ladder placement bracket for thermal power plants. Background Technology

[0002] In the daily operation and maintenance of thermal power plants, insulated ladders are key tools for ensuring the safety of workers, and their storage and management are of paramount importance.

[0003] Traditional methods of placing insulated ladders, such as haphazardly leaning against walls or using simple hangers, have numerous drawbacks. Firstly, the lack of a stable fixing structure makes the ladders susceptible to tipping over from external impacts, potentially damaging the ladder, shortening its lifespan, and posing a safety threat to surrounding personnel and equipment. Secondly, traditional hangers typically use a single fixing method, making height adjustment inconvenient and unable to accommodate the storage needs of insulated ladders of different specifications and sizes, and failing to meet diverse operational scenarios. Furthermore, due to the complex environment of thermal power plants, factors such as humidity and electrical activity can easily affect the insulation performance of insulated ladders. Traditional placement methods lack monitoring and protection measures for environmental factors, failing to provide timely warnings of potential risks. If there is leakage or induced electricity around high-voltage equipment in a thermal power plant, the metal components of traditional hangers can easily form conductive paths, threatening operational safety, reducing the insulation performance of the ladder, and greatly increasing the risk of electric shock to workers during use.

[0004] Therefore, there is an urgent need for a mounting bracket that can flexibly adapt to insulated ladders of different specifications, is stable and safe, and has environmental monitoring functions, in order to improve the operational safety and management efficiency of thermal power plants.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0029] Please see Figure 1-6 An insulated ladder placement bracket for a thermal power plant includes a base 1, at least two uprights 2 vertically mounted on the base 1, and a suspension mechanism fixed to the uprights 2. The suspension mechanism includes at least two sets of L-shaped hooks 3. Each L-shaped hook 3 has a hinge shaft 4 at the end of its short side. Multiple mounting holes 5 are equidistantly opened on the uprights 2 along the height direction. The hinge shaft 4 passes through the mounting holes 5 and is connected to a locking nut 6 by a threaded connection at the shaft end.

[0030] The long side of the L-shaped hook 3 is covered with an anti-slip insulating layer 7 with a thickness of ≥5mm. The anti-slip insulating layer 7 is a composite layer of silicone rubber and epoxy resin.

[0031] The top surface of the base 1 is provided with a matrix of threaded holes 8, which supports the installation of multiple columns 2.

[0032] In this embodiment: according to the specifications of the insulated ladder, the L-shaped hook 3 is adjusted by passing through the mounting hole 5 on the column 2 via the hinge shaft 4, and fixed with the locking nut 6, so that the hook can adapt to the suspension requirements of the insulated ladder; when it is necessary to adjust the height of the column 2, the multi-section hollow tube 9 is nested and engaged by the convex snap-fit ​​block 10 and the concave snap-fit ​​groove 11, and fastened with the U-shaped nylon clamp 12, so as to realize the flexible adjustment of the height of the column 2; the pressure sensor 21 at the end of the insulating support foot 20 at the bottom of the base 1 monitors the force on the insulating support foot 20 in real time. When the pressure is abnormal, the signal is transmitted to the audible and visual alarm indicator 22 to issue an audible and visual alarm; the humidity detection module 24 integrated in the polytetrafluoroethylene cap 23 at the top of the column 2 monitors the ambient humidity in real time. When the humidity exceeds the standard, the signal is transmitted to the audible and visual alarm indicator 22 to trigger the alarm; and through the multi-level insulation design, the current conduction path of the metal parts is blocked to ensure that the bracket can still be used safely in a live environment.

[0033] As a technical optimization of this utility model, the column 2 is composed of multiple hollow tubes 9. Each hollow tube 9 has a convex snap-fit ​​block 10 and a concave snap-fit ​​groove 11 processed at its upper and lower ends, respectively. Adjacent hollow tubes 9 are nested and interlocked by the convex snap-fit ​​block 10 and the concave snap-fit ​​groove 11, and the connection is fastened by a U-shaped nylon clamp 12. The outer wall of the convex snap-fit ​​block 10 and the inner wall of the concave snap-fit ​​groove 11 are provided with an alumina ceramic insulating coating 13. The thickness of the alumina ceramic insulating coating 13 is 0.2-0.3mm, and the surface roughness Ra≤3.2μm.

[0034] In this embodiment: the column 2 is composed of multiple hollow tubes 9, which allows for flexible height adjustment of the column 2. The adjacent tubes are nested by convex snap-fit ​​blocks 10 and concave snap-fit ​​grooves 11 to ensure structural stability. The U-shaped nylon clamps 12 bridge the segmented connection and are locked with nuts to enhance the stability of the connection between adjacent tubes, prevent the column 2 from loosening during use, improve shear resistance, and provide insulation. This also allows the bracket to adapt to different height requirements and ensures insulation safety.

[0035] As a technical optimization of this utility model, the column 2 and the base 1 are connected by a flange 14 and a connecting bolt 15. A butyl rubber insulating pad 16 is provided between the flange 14 and the base 1, and the surface of the connecting bolt 15 is covered with a silicone rubber insulating sleeve 17.

[0036] In this embodiment: flange 14, butyl rubber insulating gasket 16, and silicone rubber insulating sleeve 17 enhance the insulation performance of the connection between column 2 and base 1, block the metal conductive path, form an all-round insulation protection system, and ensure that the overall structure of the bracket is stable and the insulation is reliable.

[0037] As a technical optimization of this utility model, the inner side of the long side of the L-shaped hook 3 is provided with an arc-shaped metal limiting baffle 18. The surface of the arc-shaped metal limiting baffle 18 is provided with a hemispherical insulating rubber protrusion 19 with a diameter of 8mm and a height of 4mm, and the center distance between adjacent protrusions 19 is 15mm.

[0038] In this embodiment: when the insulated ladder beam is pressed into the L-shaped hook 3, the arc-shaped metal limiting baffle 18 is deformed by compression, and the frictional resistance is increased by the protrusions 19 to prevent the ladder from sliding and play a limiting role; by increasing the roughness of the contact surface, the frictional resistance is further increased to prevent the ladder from sliding due to vibration or external force and improve the stability of the suspension.

[0039] As a technical optimization of this utility model, the bottom of the base 1 is provided with an insulating support foot 20, the end of the insulating support foot 20 is embedded with a pressure sensor 21, and an audible and visual alarm indicator light 22 is installed on the side of the base 1. The pressure sensor 21 is electrically connected to the audible and visual alarm indicator light 22.

[0040] In this embodiment: multiple insulating feet 20 at the bottom of the base 1 ensure that the base 1 is placed stably, while the insulating material prevents current from being conducted through the base 1, ensuring safety; when the pressure value of a single insulating foot 20 exceeds the set threshold, the audible and visual alarm indicator 22 triggers a red flashing alarm, reminding the operator that the rack is in an unstable state, so as to adjust or check it in time, avoid safety accidents caused by the tilting or collapse of the base 1, and realize intelligent safety monitoring.

[0041] Pressure sensor 21 is a microelectromechanical system (MEMS) pressure sensor.

[0042] As a technical optimization of this utility model, the top of the column 2 is provided with a detachable polytetrafluoroethylene cap 23, and the cap 23 integrates a humidity detection module 24, which is electrically connected to the audible and visual alarm indicator 22.

[0043] In this embodiment: the sensor probe extends to the outer surface of the cap 23, and the detection data is transmitted to the audible and visual alarm indicator 22 via Bluetooth module. When the ambient humidity is >85% RH, the audible and visual alarm indicator 22 will activate a yellow constant-on alarm to remind the operator that the current ambient humidity is high, so as to prevent the insulation performance from being affected by moisture and ensure that the equipment is used in a safe humidity environment.

[0044] As a technical optimization of this utility model, the side of the column 2 is provided with a specification marking area 25 printed with fluorescent insulating coating, and the specification marking area 25 is provided with scale lines and trapezoidal markings.

[0045] In this embodiment: the specification marking area 25 on the side of the column 2 is printed with fluorescent insulating coating, which makes it easy to view the rack specification information, facilitates use and management, and improves work efficiency.

[0046] Working principle and usage process of this utility model:

[0047] Based on actual usage requirements, select an appropriate number of columns 2. Install the columns 2 onto the base 1 using the matrix-style threaded hole group 8 on the top surface of the base 1, along with flanges 14 and connecting bolts 15. Place a butyl rubber insulating pad 16 between the flange 14 and the base 1, and cover the connecting bolts 15 with silicone rubber insulating sleeves 17 to ensure a stable connection and good insulation. If the height of the columns 2 needs adjustment, sequentially interlock multiple hollow tube sections 9 using convex snap-fit ​​blocks 10 and concave snap-fit ​​grooves 11. Secure the connection of each hollow tube section 9 with U-shaped nylon clamps 12. After adjusting to the appropriate height, install a PTFE cap 23 at the top of the column 2. Insert the hinge shaft 4 of the L-shaped hook 3 through the mounting hole 5 at a suitable position on the column 2. Adjust the hook angle according to the specifications of the insulated ladder and secure it with a locking nut 6 to ensure the L-shaped hook 3 is installed correctly. The ladder is securely mounted at the correct angle. It is hung on the L-shaped hook 3, with the arc-shaped metal limiting baffle 18 and hemispherical insulating rubber protrusions 19 on the inner side of the long side restricting its position and preventing swaying. The level of the bracket is adjusted via the insulating feet 20. The pressure sensor 21 monitors the force on the insulating feet 20 in real time. When the pressure is abnormal, the audible and visual alarm indicator 22 sounds an alarm, prompting staff to check and adjust. The humidity detection module 24 monitors the ambient humidity in real time. When the humidity exceeds the standard, the audible and visual alarm indicator 22 triggers an alarm, reminding staff to take appropriate measures to ensure the bracket is used in a suitable environment. Staff can view the bracket specifications through the specification marking area 25 on the side of the column 2 for convenient use and management. During use, the status of each component of the bracket should be checked regularly to ensure its normal operation and safety performance.
