Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for power equipment maintenance, and in particular to a modular guardrail for power equipment maintenance. Background Technology

[0002] In the field of power equipment maintenance, safety protection is of paramount importance. Traditional maintenance site protection often uses temporary simple guardrails or warning tapes. As the scale of power equipment continues to expand and the complexity of maintenance operations increases, the requirements for protective facilities are also increasing. With the rapid development of the social economy, the stability and security of power supply are receiving more and more attention, and the frequency and scale of power equipment maintenance are also increasing accordingly. This places higher demands on the safety management of maintenance sites.

[0003] A search revealed Chinese Patent Publication No. CN205777194U, which discloses a modular guardrail. The core of this guardrail consists of horizontal and vertical bar modules, along with a surface tube and posts. The key feature is that the horizontal and vertical bar modules are connected to posts on both sides, with the upper ends of the posts connected to the surface tube. Each horizontal and vertical bar module includes both horizontal and vertical bars. This new design boasts significantly higher strength and reliability than commonly used modular guardrails, thanks to its standardization and modularity, enabling rapid industrial production. Standardization and modularity also ensure increased reliability of on-site construction dimensions and reduce uncontrollable factors caused by variations in construction personnel. However, this design does not consider the flexibility of the device; it cannot be moved easily when working in different locations, requiring manual handling, which greatly impacts work efficiency and time. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a modular guardrail for power equipment maintenance, which aims to improve the problem that existing technologies cannot be moved at any time when working in different locations, requiring manual handling, which greatly affects work efficiency and time.

[0006] Through the above technical solution: the sliding connection between the bottom inner side of the column and the fixing rod ensures the flexibility and stability of the structure; the right side of the fixing rod is fixedly connected to the fixing column, forming a stable support system; the inner side of the fixing rod is fixedly connected to the locking block, which not only enhances the stability of the structure but also provides additional fixing function; a spring is fixedly connected inside the column, and its bottom end is fixedly connected to the fixing block, providing the necessary elasticity and buffering capacity for the entire structure; two holes are opened on the inner side of the fixing block to meet structural requirements; the bottom end of the fixing block is fixedly connected to the universal wheel, making the entire structure more flexible and free to move; the bottom outer side of the column is fixedly connected to the support plate to enhance its load-bearing capacity and stability; a disassembly mechanism is provided on the outer side of the column to facilitate users to quickly disassemble and maintain parts of the structure.

[0007] As a further description of the above technical solution:

[0008] The disassembly mechanism includes a fixing plate. The outer side of the column is threadedly connected to the inner side of the fixing plate. A hole is opened on the inner side of the column. A crossbeam is slidably connected to the inner side of the hole. A connector is slidably connected to the outer side of the crossbeam. A screw is threadedly connected to the inner side of the column. A nut is threadedly connected to the outer side of the screw.

[0009] Through the above technical solution: the outer side of the column is threadedly connected to the inner side of the fixing plate, ensuring the stability and durability of the structure. A hole is opened on the inner side of the column, and the inner side of the hole is slidably connected to the crossbeam, allowing the crossbeam to move flexibly horizontally inside the column. The outer side of the crossbeam is slidably connected to the connector, which not only enhances the flexibility of the structure but also provides additional support points. The inner side of the column is threadedly connected to the screw, and the outer side of the screw is threadedly connected to the nut, ensuring the stability of the connection.

[0010] As a further description of the above technical solution:

[0011] A decorative strip is fixedly connected to the front side of the fixing plate, and a warning light is fixedly connected to the top of the fixing plate.

[0012] The above technical solution involves a fixed connection between the front end of the fixing plate and the decorative strip, ensuring the stability of the structure. The top of the fixing plate is fixedly connected to the warning light to provide a conspicuous visual warning when necessary, thereby enhancing safety performance.

[0013] As a further description of the above technical solution:

[0014] The inner side of the second hole is slidably connected to the outer side of the fixing rod, and the inner side of the column is slidably connected to the outer side of the caster wheel.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the pushing device uses the universal wheel to move to the target position, rotates the fixed column to make the locking block vertical, thereby pulling out the fixed rod and column, causing the universal wheel to lose support and retract into the interior of the column under the action of gravity of the device, and pushes the fixed block. The fixed block then squeezes the spring, and finally makes the support plate contact the ground, realizing the change of the equipment position, making the equipment more flexible and able to quickly adapt to changes in the work site.

[0030] 2. In this utility model, after long-term use of the equipment, maintenance is required. First, rotate the fixed column, then pull out the fixed rod, and then loosen the nut and screw to make the crossbeam lose its fixation and loosen it. After the crossbeam is no longer restrictive, the column can be turned to remove it from the inside of the fixed plate. This realizes the disassembly of the device, which facilitates the replacement and maintenance by the staff and prevents some devices from becoming unusable due to the long time, thus affecting the normal use of the equipment.

When it reaches the target location, the fixed column 4 is rotated, which in turn rotates the locking block 7, so that the locking block 7 is in a vertical position. The fixed rod 3 can then be pulled out from the hole 6 and then from the column 1. When the caster wheel 8 loses the support of the fixed rod 3, under the pressure of gravity, the caster wheel 8 will retract into the inside of the column 1, and push the fixed block 5 to squeeze the spring 9. Finally, the support plate 10 contacts the ground, realizing the change of the equipment position, making the equipment more flexible and able to quickly adapt to changes in the work site.

[0048] After prolonged use, the equipment requires maintenance. First, rotate the fixed column 4 and pull the fixed rod 3 out of the inside of the column 1. Then, turn the nut 205 and then the screw 204 to loosen the crossbeam 201 and pull it out. Once the column 1 is no longer restricted by the crossbeam 201, turn the column 1 to unscrew it from the inside of the fixing plate 202. This allows for the disassembly of the device, facilitating replacement and maintenance by staff and preventing parts of the device from becoming unusable due to prolonged use, thus affecting the normal operation of the equipment.
