Description

Technical Field

[0001] This utility model belongs to the technical field of engineering protection equipment for civil engineering and bridge construction, and particularly relates to a safety enclosure device for civil engineering and bridge construction. Background Technology

[0002] Construction guardrails are temporary protective facilities set up to ensure the safety of construction areas. They are mainly used to separate construction areas from non-construction areas, prevent unauthorized personnel and vehicles from accidentally entering the work site and causing safety accidents, and also block the impact of falling materials and dust on the surrounding environment during construction.

[0003] Since conventional construction guardrails mainly protect workers by using the weight of heavy blocks, it is difficult to transport and place these heavy blocks on roads and bridges. Directly placing them on the side of the guardrail lacks protective capacity, resulting in the low practicality of conventional construction guardrails for road and bridge protection.

[0004] Therefore, we propose a safety enclosure device for civil engineering bridge and road projects to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that conventional construction guardrails are not very practical for road and bridge protection, and to propose a safety enclosure device for civil engineering road and bridge projects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A safety enclosure device for civil engineering bridges and roads includes a hook frame with a pressure hook slidably inserted inside. The upper part of the pressure hook is slidably sleeved on the hook frame, and a bolt is threaded onto the upper part of the pressure hook. The bolt is tightened and matched with the hook frame. A retaining net is fixedly connected to the side of the hook frame. The hook frame and pressure hook are symmetrically distributed on the side of the retaining net. The hook frame and pressure hook are clamped to the side of the target bridge or road, and then the hook frame and pressure hook are tightened by screwing in the bolt. The bolt is used to fix the clamped state of the hook frame and pressure hook. The hook frame is hooked to the side of the bridge or road, and the bearing force of the bridge edge is used to ensure the stability of the protection while improving the ease of installation.

[0008] Preferably, a spring is fitted onto the upper part of the hook frame, the lower end of the spring is fixedly connected to the hook frame, and the upper end of the spring is fixedly connected to the pressure hook. The spring acts upward on the pressure hook, ensuring that the hook frame and pressure hook are pre-clamped during installation, facilitating bolt tightening.

[0009] Preferably, the hook frame includes a fixed column, the lower end of which is fixedly connected to a first guide sleeve, and a guide column is fixedly connected between the fixed column and the first guide sleeve. A hook is fixedly connected to one end of the first guide sleeve. The guide column guides the upper part of the hook to slide, the first guide sleeve guides the lower part of the hook to slide, and the hook is used to hook onto the edge of the target bridge to bear the impact force and ensure the overall strength.

[0010] Preferably, the hook frame further includes a stop block, the upper end of which is fixedly connected to the lower end of the first guide sleeve. The stop block increases the support range for the pressure hook.

[0011] Preferably, the pressing hook includes a lifting bar, a second guide sleeve is fixedly connected to the middle of the lifting bar, and a hook body is fixedly connected to the lower end of the lifting bar. A bolt is threaded into the second guide sleeve and passes through the second guide sleeve. The second guide sleeve is slidably sleeved outside the guide post, and the lifting bar slides through the first guide sleeve. Loosening the bolt releases the guide post, pushes the lifting bar downward, and opens the gap between the hook body and the hook. The hook body and hook are then placed on the side of the bridge. The spring force acts upward on the second guide sleeve, which in turn acts upward on the lifting bar, pressing the hook body against the lower end of the target bridge. Tightening the bolt secures the second guide sleeve to the guide post, facilitating the installation of the hook frame and pressing hook on the target bridge.

[0012] Preferably, the barrier net includes a frame, with a net fixedly connected inside the frame, and the side ends of the frame fixedly connected to fixed posts. The net effectively prevents workers from crossing the boundary.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. Clamp the hook frame and pressure hook on the side of the target road and bridge, then tighten the hook frame and pressure hook and tighten the bolts. Use the bolts to fix the clamped state of the hook frame and pressure hook. Use the hook frame to hook on the side of the road and bridge and use the load-bearing force of the road and bridge edge to ensure the stability of the protection while improving the ease of installation.

[0015] 2. The spring acts upward on the pressure hook, so that the hook frame and pressure hook are in a pre-clamped state when they are ready for installation, making it easy to tighten the bolts.

[0016] 3. The upper part of the pressure hook is guided to slide using the guide column, and the lower part of the pressure hook is guided to slide using the first guide sleeve. The hook is used to hook the edge of the target bridge to bear the impact force and ensure the overall strength.

[0017] 4. Loosen the bolts to release the guide post, push the lifting bar downwards to open the gap between the hook and the hook body, and place the hook and hook body on the side of the bridge. Use the spring force to act upwards on the second guide sleeve, which in turn acts upwards on the lifting bar, pressing the hook body against the lower end of the target bridge. Tighten the bolts to fix the second guide sleeve to the guide post, making it easy to install the hook frame and pressure hook on the target bridge. Attached Figure Description
