Description

Technical Field

[0001] This utility model relates to the field of construction safety, specifically to a suspension device for a safety belt during the construction of concrete crash barriers. Background Technology

[0002] During the construction of concrete crash barriers for bridges, workers need to stand above the formwork to vibrate the concrete to ensure its quality. However, due to the narrow working area, lack of reliable edge protection facilities, and the absence of effective anchor points for safety belts and ropes, there is a risk of falls from height. Existing safety measures typically rely on temporary welded supports to secure safety belts or ropes. These traditional methods are not only extremely unstable and prone to causing accidents, but also severely reduce construction efficiency because workers need to frequently re-attach their safety belts. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a safety belt suspension device for concrete crash barrier construction. By providing a structurally stable, easy-to-install and dismantle, and widely applicable safety belt suspension device, it solves the problems of insufficient safety protection and inflexible operation during high-altitude operations in the construction of concrete crash barriers.

[0004] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method: A safety belt suspension device for concrete crash barrier construction includes a pole, which is vertically installed and connected to the outside of the crash barrier. The upper end of the pole is provided with a clamp, and the clamp has a connecting hole on the side near the crash barrier for connecting a safety rope. The lower end of the pole is provided with a base, and the lower end of the base is fixedly connected to the outside of the crash barrier.

[0005] With this invention, the pole itself is connected to the crash barrier, and a base is set at the lower end of the pole. The fixed connection between the base and the crash barrier further strengthens the connection stability between the pole and the crash barrier, ensuring the safety of workers during construction.

[0006] Preferably, the base includes a base plate and a vertical tube for inserting the lower end of the upright, the lower end of the upright being vertically connected to the upper surface of the base plate.

[0007] With this utility model, the base plate is fixedly connected to the anti-collision guardrail, while the upright is perpendicular to the upper surface of the base plate and inserted into the lower end of the upright. The upright plays a role in limiting the horizontal direction of the upright.

[0008] Preferably, the upper surface area of ​​the base plate is larger than the lower end face area of ​​the upright, and the upper surface of the base plate can completely cover the lower end face of the upright.

[0009] With this invention, the base plate is fixedly connected to the crash barrier, and the area of ​​its upper surface is greater than the area of ​​the lower end face of the upright. That is, the width of the upper surface of the base plate is greater than the diameter of the end face of the upright, thereby stably supporting the lower end of the upright and preventing the upright from loosening and falling off relative to the crash barrier.

[0010] Preferably, the outer side of the crash barrier has a reserved hole corresponding to the connection of the upright, and the lower middle part of the upright has a bolt that matches the reserved hole.

[0011] This invention provides a bolt for connecting and fixing to the crash barrier at the lower middle part of the upright, a pre-drilled hole at the corresponding connection point on the outer side of the crash barrier, and preferably, a nut corresponding to the bolt is provided or welded to the upright to fix it to the crash barrier. The fixing position is set at the lower middle part of the upright, which ensures both the stability of the upright and the extension length of the upper end of the upright relative to the crash barrier.

[0012] Preferably, the clamp includes a post mating hole for surrounding the upright, and a fixing hole and a fastener that mates with the fixing hole are provided on the side of the clamp away from the guardrail. The fixing hole and the fastener are used to adjust the diameter of the post mating hole.

[0013] This invention utilizes a clamp to connect the safety rope to the upright, thereby allowing for flexible adjustment of the safety rope's position on the upright while ensuring the stability of the connection. When adjustment is needed, simply operate the fastener on the fixing hole to enlarge the mating hole on the upright, then move the clamp. Once the clamp is in the appropriate position, operate the fastener again to reduce the diameter of the mating hole.

[0014] Preferably, a rope clip for securing the safety rope is provided between the safety rope and the connecting hole.

[0015] This invention utilizes rope clips to secure the safety rope to the connecting hole, preventing slippage or detachment during use through mechanical clamping. The rope clips are simple in design, easy to operate, and provide strong clamping force. Construction workers can quickly secure the safety rope to the clamp or adjust it as needed, thereby improving construction efficiency and reducing time wasted on installing or adjusting the safety rope. Simultaneously, it evenly distributes the tension on the wire rope, reducing fatigue fracture caused by localized stress concentration and preventing wear during use, thus extending the service life of the safety rope.

[0022] In this embodiment, the pole 120 is connected to the crash barrier 000, and a base 110 is provided at the lower end of the pole 120. The fixed connection between the base and the crash barrier 000 further strengthens the connection stability between the pole 120 and the crash barrier 000, ensuring the safety of workers during the construction process.

[0023] In this embodiment, the base 110 includes a base plate 410 and a vertical tube 420 for inserting the lower end of the upright 120. The lower end of the vertical tube 420 is vertically connected to the upper surface of the base plate 410. The lower end of the vertical tube 420 and the upper surface of the base plate 410 can be fixedly connected to improve the overall stability of the device.

[0024] In this embodiment, the base plate 410 of the base 110 is fixedly connected to the anti-collision guardrail 000, while the upright tube 420 is perpendicular to the upper surface of the base plate 410. The upright tube 420 is inserted into the lower end of the upright 120, and the upright tube 420 plays a limiting role in the horizontal direction of the upright 120.

[0025] In this embodiment, the upper surface area of ​​the base plate 410 is larger than the lower end face area of ​​the upright 120, and the upper surface of the base plate 410 can completely cover the lower end face of the upright 120.

[0026] In this embodiment, the base plate 410 is fixedly connected to the guardrail 000, and the area of ​​its upper surface is greater than the area of ​​the lower end face of the upright 120. That is, the width of the upper surface of the base plate 410 is greater than the diameter of the end face of the upright, thereby stably supporting the lower end of the upright 120 to prevent the upright 120 from loosening and falling off relative to the guardrail 000.

[0027] In this embodiment, the outer side of the crash barrier 000 is provided with a reserved hole corresponding to the connection of the upright 120, and the lower part of the middle of the upright 120 is provided with a bolt 130 that is connected to the reserved hole.

[0028] In this embodiment, a bolt 130 is provided at the lower middle part of the upright 120 for connection and fixation with the crash barrier 000. A reserved hole is provided at the corresponding connection point on the outside of the crash barrier 000. Preferably, a nut corresponding to the bolt 130 is provided, or a nut corresponding to the bolt 130 is welded and fixed to it, for fixing the upright 120 itself to the crash barrier 000. The fixing position is set at the lower middle part of the upright, which ensures both the stability of the upright 120 itself and the extension length of the upper end of the upright 120 relative to the crash barrier.

[0029] In this embodiment, the clamp 140 includes a column mating hole 310 for surrounding the upright 120. The clamp 140 is provided with a fixing hole 220 and a fastener that mates with the fixing hole 220 on the side away from the crash barrier 000.

[0030] In this embodiment, a clamp 140 is used to connect the safety rope 150 to the upright 120. This allows for flexible adjustment of the connection position of the safety rope 150 on the upright 120 while ensuring the stability of the connection. When adjusting the connection position of the safety rope 150 on the upright 120, simply operate the fastener on the fixing hole 220 to enlarge the upright mating hole 310, then move the clamp 140. After moving the clamp 140 to the appropriate position, operate the fastener again to reduce the diameter of the upright mating hole 310.

[0031] In this embodiment, a rope clip for fixing the safety rope 150 is provided between the safety rope 150 and the connecting hole 210.

[0032] In this embodiment, a rope clamp is used to fix the safety rope 150 to the connecting hole 210. The mechanical clamping method prevents the safety rope from slipping or falling off during use. The rope clamp is simple in design, easy to operate, and has a strong clamping force. Construction workers can quickly fix the safety rope to the clamp or adjust it when needed, thereby improving construction efficiency and reducing the time wasted on installing or adjusting the safety rope. At the same time, it evenly distributes the tension on the wire rope, reducing fatigue fracture of the wire rope caused by local stress concentration, preventing wear of the wire rope during use, and thus extending the service life of the safety rope.
