Description
Technical Field
[0001] This utility model relates to the field of safety protection technology for electromechanical engineering construction, and in particular to a safety protection fence for electromechanical engineering construction sites. Background Technology
[0002] During the construction of electromechanical engineering, areas such as temporary distribution boxes, cutting machines, and material storage areas pose safety hazards such as electrical risks, mechanical injuries, and accidental personnel entry. Protective fences are needed to achieve physical isolation and risk warnings to ensure the safety of construction personnel and the order of operations. Currently, the protective fences for electromechanical engineering construction sites on the market are mainly divided into two types: fixed and mobile. However, both have obvious shortcomings in practical applications and are difficult to adapt to the complex scenario of alternating long-term and temporary areas under indoor hardened cement floors and multiple risks. Existing fixed fences are mostly assembled with steel pipe fasteners or pre-embedded mesh structures, and are rigidly fixed to the ground by welding or expansion bolts. Although they can meet the long-term stability requirements of the area, they are prone to damage to components when disassembled, and cannot be reused in different construction areas, resulting in idle equipment and wasted costs. Moreover, these fences usually only support straight splicing. When facing right-angle corners or other irregular areas, the splicing gaps are large, which can easily create blind spots and do not meet safety isolation standards. Mobile fences mostly rely on lightweight mesh structures and simple counterweight bases for support. Although they are easy to move, the bases are mostly cylindrical with flat bottoms, resulting in a high center of gravity and insufficient friction with the ground. They are prone to tipping over under external force collisions such as personnel walking or material handling, and their stability cannot meet the protection needs of high-risk scenarios such as temporary electrical equipment and mechanical operations. Meanwhile, the height of mobile fences is mostly fixed. When the height of materials stacked inside the fence changes or other protective facilities are needed, the protection range cannot be flexibly adjusted, and the protection may fail due to insufficient height.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0019] Please see Figure 1-6 This utility model provides a technical solution: a safety guardrail for electromechanical engineering construction site, including a column body 1, an arc-shaped cover 2 fixedly connected to the top of the column body 1, a slot 9 provided on the column body 1, and insertion fixing holes 10 provided on both sides of the slot 9 on the column body 1 at corresponding positions. The bottom of the column body 1 is fixedly connected to a weighted base 3. The weighted base 3 is provided with four column fixing holes 7. The four column fixing holes 7 are distributed around the circumference of the weighted base 3. The column body 1 can be fixed to the weighted base 3 with bolts through the column fixing holes 7. The bottom of the weighted base 3 is fixedly connected to a nitrile rubber anti-slip pad 4. The weighted base 3 adopts a frustum-shaped structure with a smaller top and a larger bottom, which lowers the center of gravity and improves the anti-tipping ability. The bottom is fixed with a nitrile rubber anti-slip pad 4, which will not cause the base to slip or scratch the ground. The top groove fits the column body 1 with a gap to achieve quick positioning. If there is a right-angle bend on site, a connector 5 is fixedly connected between two adjacent column bodies 1 at the right-angle position. After the connector 5 is inserted into the slot 9, the connector 5 can be fixed with bolts through the insertion fixing hole 10. When the column bodies 1 are arranged in a straight line, it is not necessary to install the connector 5. A mesh frame 8 is provided on one side of the column body 1. Frame grooves 14 are provided on the mesh frame 8 on the two sides adjacent to the column body 1. A locking body 19 is slidably connected in the frame groove 14. A spring 18 is fixedly connected in the locking body 19. A buckle 17 is fixedly connected to the spring 18. The locking body 19 is connected to the buckle groove 9. The buckle 17 and the spring 18 cooperate to lock and fix the mesh frame 8. A locking hole 13 is provided on the mesh frame 8. The locking body 19 can slide up and down in the frame groove 14 and then be fixed with bolts through the locking hole 13, thereby indirectly adjusting the position and height of the mesh frame 8. The locking body 19, spring 18, and buckle 17 constitute a quick-locking mechanism; The surface of the column body 1 has evenly spaced slots 9, which, together with the fixing holes 10 on both sides, can be used for both quick-lock snap-fit connection and bolt fastening of the connector 5. The bottom has a reserved column fixing hole 7, which can be selectively connected to the weighted base 3 or directly fixed to the ground with expansion screws, realizing multiple column fixing modes. The locking body 19 can slide along the frame slide groove 14 of the mesh frame 8, and engage with the buckle 17 driven by the spring 18 and the column buckle groove 9 to achieve a quick connection that locks with a push. At the same time, it can be locked by bolts through the locking fixing hole 13, which can fix the position and adjust the height of the mesh. Reflective strips 15 are fixedly connected to the top and bottom sides of the front of the mesh frame 8. FRP edging 12 is fixedly connected to the inner wall of the mesh frame 8. A steel wire mesh body 11 is fixedly connected inside the mesh frame 8. A fireproof baffle 6 is movably connected to the steel wire mesh body 11. A Velcro strap 16 is set on the back of the fireproof baffle 6. The Velcro strap 16 is bonded to the steel wire mesh body 11. The fireproof baffle 6 is made of fiberglass cloth with a silicone coating to specifically resist welding sparks. It is bonded to the steel wire mesh body 11 on the back by the Velcro strap 16, which can be quickly installed and removed without tools.
[0020] Working principle: The main column 1 serves as the load-bearing core. The bottom is connected and fixed to the weighted base 3 through the column fixing holes 7 and bolts. The nitrile rubber anti-slip pad 4 at the bottom of the weighted base 3 increases the friction with the cement ground to ensure the vertical stability of the column. The top is installed with an arc-shaped cover 2 through interference fit to seal the column port to eliminate safety hazards. The individual columns are arranged at a spacing that matches the width of the mesh frame 8 to form the basic support points of the protective frame. The mesh frame 8 is detachably connected to the column body 1 via quick-locking buckles. The buckle body 19 is slidably installed in the frame slide groove 14 on both sides of the mesh frame 8. Pushing the buckle body 19 makes it aligned with the slot 9 of the column body 1. The spring 18 inside the buckle body 19 is in a naturally extended state, which drives the buckle 17 to be inserted into the U-shaped opening of the slot 9. The anti-slip texture on the inside of the buckle 17 engages with the inner wall of the slot 9, completing the initial fixation of the mesh and the column. If a stronger connection is required, the buckle body 19 can be locked in position with bolts through the buckle fixing hole 13 on the mesh frame 8 to prevent it from sliding in the frame slide groove 14. The front end of the quick-locking buckle is fixed through the insertion fixing hole 10. After multiple sets of mesh units are connected through the column, a continuous protective isolation surface is formed. For right-angle corner areas, two adjacent column bodies 1 are connected by connector 5. After connector 5 is inserted into slot 9, it is aligned with the insertion fixing hole 10 of column body 1. Bolts are inserted into the insertion fixing hole 10 to complete the fastening, so that a 90° sealed transition is formed at the corner to avoid the formation of protective gaps. When temporary isolation is required, support is provided only by the weighted base 3. The column body 1 is inserted into the circular groove at the top of the weighted base 3 and fixed with bolts. The cast iron material of the weighted base 3 provides sufficient counterweight. Combined with the high friction coefficient of the nitrile rubber anti-slip pad 4, it can resist lateral thrust and prevent the fence from tipping over, meeting the stability requirements of temporary scenarios. When moving, simply remove the connecting bolts between the column and the base to move the column and the mesh individually, achieving rapid transfer and reuse. When used in long-term areas, the weighted base 3 can be removed and the column body 1 can be directly connected to the cement ground through the bottom hole with expansion bolts. After the expansion bolts are inserted into the holes, they engage with the plastic expansion tubes pre-embedded in the ground to form a rigid fixed structure of column-expansion bolt-ground, which can withstand lateral tension and ensure that the fence will not shift or tilt during long-term use. The wire mesh 11 inside the mesh frame 8 adopts a dense mesh design, which can effectively prevent people from reaching out to touch temporary power distribution boxes, cutting machines and other equipment inside the fence. At the same time, the height of the mesh and the spacing of the posts are matched to form an anti-climbing barrier. The FRP edging 12 on the inner wall of the mesh frame 8 wraps the edge of the wire mesh 11 to prevent the wire from breaking and scratching people, while enhancing the connection strength between the mesh and the frame and preventing the mesh from deforming and failing. The red and white warning colors on the surface of the main column 1 and the reflective strips 15 on the front of the mesh frame 8 form a double warning. The reflective strips 15 are made of microprism reflective material, which can form a certain distance of visibility under indoor lighting. Even in the construction environment with insufficient light, it can remind people to pay attention to the protection boundary. If it is necessary to strengthen the risk warning, warning signs can be installed on the mesh frame 8 to further clarify the risk type. For the high-temperature sparks generated by the cutting machine, the fireproof baffle 6 provides targeted protection. The fireproof baffle 6 is made of flame-retardant material with fiberglass cloth and silicone coating. The Velcro strap 16 on the back is bonded and fixed to the wire mesh body 11. The bottom of the baffle is in contact with the ground, which can prevent sparks from splashing outside the fence or igniting surrounding materials. When fireproofing is not required, the Velcro strap 16 can be torn off and the baffle can be removed without affecting the normal use of the fence. When the protection height needs to be adjusted during construction, the height of the mesh can be adjusted by sliding the locking body 19 with the frame slide 14. Loosen the bolts in the locking holes 13 on the mesh frame 8, push the locking body 19 up and down along the frame slide 14, and drive the mesh frame 8 to rise and fall synchronously. After adjusting to the target height, re-lock the position of the locking body 19 by passing the bolts through the locking holes 13, and the height of the mesh can be fixed, so as to achieve flexible adaptation of the protection range and avoid protection failure due to insufficient height.
[0021] Structural Description: The main post 1 is a cylindrical structure made of FRP material, serving as the vertical load-bearing frame of the entire fence. It connects to the arc-shaped cap 2 at the top and the weighted base 3 at the bottom, while also providing the installation foundation for the side mesh frame 8 and connectors 5. The red and white warning colors on the surface can visually remind people to pay attention to the protective boundary, achieving basic risk warning. Arc-shaped cap 2: Connected to the top of the column body 1 with an interference fit, sealing the top opening of the column body 1 to prevent dust and small particles of debris from entering the column during construction and causing blockage or corrosion. It also eliminates the risk of scratches from sharp ends, improving safety during use. Weighted base 3: Made of cast iron, it features a frustum-shaped structure that is smaller at the top and larger at the bottom. A circular groove is cut into the center of the top, utilizing the high density of cast iron to provide sufficient counterweight. Combined with the frustum-shaped structure, this significantly lowers the center of gravity of the fence, enhancing its resistance to tipping. The circular groove at the top fits snugly with the outer wall of the main column 1, enabling quick positioning and installation of the column. Nitrile rubber anti-slip mat 4: With anti-slip textured surface, it is adhesively attached to the bottom of the weighted base 3. The high friction of the rubber material increases the friction between the base and the ground, preventing the fence from sliding under external forces. It also cushions the direct contact between the base and the ground, avoiding scratches. Connector 5: Matching interfaces are provided on both sides corresponding to the slots 9 and fixing holes 10 of the inserts on the main body 1 of the column. It connects two adjacent main bodies 1 at right angles. During installation, it is inserted into the slots 9 of the two columns and tightened with bolts to form a sealed transition in the right angle area, avoiding the protective gaps caused by conventional splicing. Fireproof baffle 6: Connected to the wire mesh body 11 via Velcro 16, it specifically resists the high-temperature sparks generated by the cutting machine, achieving flame-retardant protection and preventing sparks from igniting surrounding materials. The bottom of the baffle is flush with the ground to form a closed fire barrier. Column fixing holes 7: These are threaded holes, evenly distributed along the circumference of the circular groove on the top of the weighted base 3. Bolts are inserted into these holes to securely connect the column body 1 to the weighted base 3, ensuring that there is no relative displacement between the two. This also provides an interface for future switching of the fixing mode. Mesh frame 8: Frame grooves 14 are provided on both sides of the frame corresponding to the positions of the column body 1, serving as the installation carrier for the wire mesh 11. Quick-locking buckles are connected through the frame grooves 14 on both sides to achieve a detachable connection with the column body 1. The frame structure ensures the overall rigidity of the mesh. Slot 9: Spacingd along the length of the column body 1, with rounded edges at the openings, providing an insert-type installation base for the quick-lock and connector 5, achieving initial positioning, reducing the difficulty of alignment for bolt fixing, and the rounded corner design prevents scratching the surface of the components during installation. Insert fixing holes 10: Symmetrically arranged on both sides of each slot 9, the connector 5 inserted into the slot 9 is further tightened by bolts inserted into the holes, preventing the connecting parts from loosening and falling off, and enhancing the stability of the splicing structure. Wire mesh 11: A mesh structure woven from epoxy resin coated steel wire, fixedly installed inside the mesh frame 8. Its dense mesh structure prevents personnel from touching the equipment inside the fence, and, in conjunction with the spacing of the posts, forms an anti-climbing barrier. The epoxy resin coating enhances corrosion resistance. FRP edging 12: Securely wraps around the perimeter of the wire mesh 11, sealing off any broken edges to prevent sharp wires from injuring workers. It also strengthens the connection between the wire mesh and the mesh frame 8, preventing the mesh edges from detaching or deforming. Locking hole 13: A circular through hole, evenly spaced along the length of the frame groove 14 on the edge of the mesh frame 8. When the locking body 19 slides to the target height, a bolt is inserted into the hole to lock the position of the locking body 19, preventing it from sliding and thus fixing the height of the mesh frame 8. Frame groove 14: Located on the outer side of both sides of the mesh frame 8, extending along the length of the frame, providing a sliding track for the locking body 19. This allows the locking body 19 to move up and down along the groove, adjusting the height of the mesh frame 8 to suit different protection needs. Reflective strip 15: Fixedly affixed to the upper and lower sides of the front of the mesh frame 8. In low-light conditions, it enhances the visibility of the fence through the reflective properties of the microprism. Combined with the red and white warning colors of the main post 1, it forms a double warning, reminding people to avoid the protected area. Velcro 16: This is a combination of hook and loop fasteners made of nylon, which are fixed to the back of the fireproof baffle 6 and the surface of the wire mesh 11, respectively. This allows for quick bonding and fixing of the fireproof baffle 6 and the wire mesh 11, enabling installation and removal without tools and facilitating the flexible addition or removal of fireproof baffles. Buckle 17: Fixedly connected to the free end of spring 18, it snaps into the U-shaped opening of slot 9 under the pushing force of spring 18. Initial fixation is achieved through the wedge-shaped structure and the engagement with the inner wall of the slot. The anti-slip texture enhances the engagement friction. Spring 18: Fixedly installed in the internal spring groove of the latch body 19, it provides elastic driving force to push the buckle 17 into the slot 9 for quick locking and fixing. During disassembly, the spring can be compressed to disengage the buckle from the slot for easy and quick separation. Lock body 19: It slides in conjunction with the frame slide groove 14 and has a spring mounting groove inside. It serves as the main load-bearing component of the quick lock and adjusts its position by sliding within the frame slide groove 14. At the same time, it connects the mesh frame 8 and the column body 1 by cooperating with the slot 9.
