Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically a guardrail for engineering applications. Background Technology

[0002] In various engineering construction projects, safety barriers are indispensable and important safety facilities. Whether it is a construction site, a road construction site, or an infrastructure construction site such as a bridge or water conservancy project, safety barriers play a crucial role in delineating construction areas, preventing personnel from accidentally entering dangerous areas, and preventing objects from accidentally rolling down. They serve as a vital barrier to protect the lives of people inside and outside the construction site and the safety of the surrounding environment.

[0003] However, many existing engineering guardrails on the market have revealed significant instability issues in practical applications. On the one hand, construction sites are often dynamic and complex environments with numerous uncertainties, and unexpected external impacts frequently occur. For example, misoperation of construction machinery during operation may cause it to collide with the guardrail, or vehicles transporting building materials and equipment may fail to be accurately controlled when passing through or turning on the site, accidentally colliding with the guardrail. These unexpected external forces acting on the guardrail can easily cause it to shift or even collapse due to its poor structural stability, thus losing its protective function and posing a significant safety hazard to the construction site, potentially leading to serious consequences such as personal injury and property damage.

[0004] On the other hand, engineering guardrails are also vulnerable when facing severe weather conditions, especially strong winds: the strong lateral force generated by strong winds will exert a large pushing and pulling force on the guardrails, and the existing structural design and fixing methods of guardrails are often unable to effectively resist such high-intensity external forces. Many guardrails are also prone to swaying and loosening under the attack of strong winds due to unstable foundations, weak connecting parts, or insufficient wind resistance of the overall structure. Ultimately, this can lead to collapse.

[0005] In conclusion, given the shortcomings of existing engineering guardrails in terms of stability, there is an urgent need to develop a new type of engineering guardrail with stronger stability, capable of playing a solid protective role in complex and ever-changing engineering environments, reducing the possibility of safety accidents, reducing cost investment, and ensuring the safe and efficient implementation of engineering projects. Utility Model Content

[0006] The purpose of this utility model is to provide a protective railing for engineering applications to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An engineering guardrail includes a pair of support plates and a guardrail installed within the support plates. A horizontal plate is fixedly installed between the two support plates below the guardrail, and a movable plate is movably installed above the horizontal plate. A drive assembly for driving the movable plate to move up and down is also provided between the two support plates. Multiple support rods are symmetrically hinged on both sides of the movable plate, and two symmetrical support rods are connected by a tension spring. Side plates are also symmetrically fixed on both sides of the horizontal plate, and the rotation trajectory of the support rods interferes with the side plates.

[0009] As a further embodiment of this utility model: the drive assembly includes a bidirectional lead screw rotatably mounted between two support plates and a pair of connecting rods symmetrically hinged to a movable plate. Threaded bushings are symmetrically mounted on the two threaded portions of the bidirectional lead screw, and a handwheel is mounted on one end of the bidirectional lead screw that extends outside one of the support plates. The top end of the connecting rod is hinged to the threaded bushing.

[0010] As a further embodiment of this invention, a roller is also installed at the end of the side plate.

[0011] As a further embodiment of this utility model, a plurality of return springs are also installed between the movable plate and the cross plate.

[0012] As a further embodiment of this utility model: universal wheels are installed on the bottom surfaces of the two support plates, and sleeves are movably sleeved on the support plates, with the sleeves fixedly connected to the ends of the movable plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model incorporates a movable plate, foot support rods, a horizontal plate, side plates, and a drive assembly. When the drive assembly drives the movable plate downwards, the movement of the foot support rods and side plates interferes, allowing multiple foot support rods hinged to both sides of the movable plate to simultaneously extend outwards, serving as additional support feet to distribute force and enhance overall resistance to external impacts and wind. Tension springs connect the symmetrical foot support rods, ensuring they maintain a certain elastic tension during extension or retraction, which helps maintain the extended state and further stabilizes the support effect.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments. Example

[0020] Please see Figure 1-3 An engineering guardrail includes a pair of support plates 1 and guardrails 2 installed within the support plates 1. The pair of support plates 1 serve as the basic support structure for the guardrails 2, providing a stable frame for the entire structure and ensuring that the guardrails 2 can stand firmly in the construction site. The guardrails 2 installed within the support plates 1 provide direct blocking and protection, demarcating areas and preventing people and objects from crossing. A horizontal plate 3 is fixedly installed between the two support plates 1 below the guardrails 2. The horizontal plate 3 enhances the connection strength between the two support plates 1, making the structure more stable. A movable plate 4 is movably installed above the horizontal plate 3. A drive assembly for driving the movable plate 4 to move up and down is also provided between the two support plates 1. The movable plate 4 has two sides... Multiple support rods 5 are symmetrically hinged and connected, with two symmetrical support rods 5 connected by a tension spring 6. Side plates 7 are also symmetrically fixed on both sides of the horizontal plate 3. The rotation trajectory of the support rods 5 interferes with the side plates 7. When the drive assembly drives the movable plate 4 to move downward, the movement of the support rods 5 and the side plates 7 interferes, allowing the multiple support rods 5 hinged on both sides of the movable plate 4 to unfold outward simultaneously, serving as supports for the guardrail 2. This acts like additional support feet, distributing the force and improving the overall resistance to external impacts and wind. The tension spring 6 connects the symmetrical support rods 5, allowing the support rods 5 to maintain a certain elastic tension during unfolding or retraction, which helps the support rods 5 maintain their unfolded state and further stabilize the support effect.

[0021] For details, please refer to Figure 1 and Figure 3 The drive assembly includes a bidirectional lead screw 8 rotatably mounted between two support plates 1 and a pair of connecting rods 11 symmetrically hinged on a movable plate 4. Threaded bushings 10 are symmetrically mounted on the two threaded portions of the bidirectional lead screw 8, and a handwheel 9 is mounted on one end of the bidirectional lead screw 8 that extends outside one of the support plates 1. The top end of the connecting rods 11 is hinged to the threaded bushings 10.

[0022] For further details, please refer to Figure 2The end of the side plate 7 is also equipped with a roller 12. When the foot support rod 5 interferes with or contacts the side plate 7 during the unfolding or retraction process, the roller 12 can reduce the friction between the two, making the rotation of the foot support rod 5 smoother. This avoids wear of components or affects the flexibility of the foot support rod 5 due to excessive friction, extends the service life of the components, and also ensures the smoothness of the overall adjustment stability of the guardrail 2.

[0023] For further details, please refer to [link / reference]. Figure 1-3 Multiple return springs 13 are also installed between the movable plate 4 and the horizontal plate 3. The arrangement of the return springs 13 helps the movable plate 4 to return to its upward position. Example

[0024] This embodiment is an improvement on embodiment 1, specifically as follows:

[0025] Please see Figure 1-3 The bottom surfaces of the two support plates 1 are equipped with casters 14, and sleeves 15 are movably fitted onto the support plates 1. The sleeves 15 are fixedly connected to the ends of the movable plates 4. The casters 14 installed on the bottom surfaces of the support plates 1 facilitate the overall movement of the guardrail 2. When the position of the guardrail 2 needs to be adjusted in the construction site, there is no need to spend a lot of manpower to move it. The guardrail 2 can be easily moved by simply pushing it and letting the casters 14 roll. This improves the flexibility and convenience of the guardrail 2 arrangement. The sleeves 15 allow the movable plates 4 to slide along the support plates 1 during the up and down movement, playing a guiding and auxiliary support role, ensuring the stability of the movement trajectory of the movable plates 4 and avoiding skewing. In addition, after the end of the sleeves 15 contacts the ground, it can brake the casters 14, fixing the support rod to the ground and fixing the position of the entire guardrail 2.

[0026] Operating Procedure: When using the guardrail 2, first move the guardrail 2 to the predetermined position on the construction site and use the casters 14 to move it easily, ensuring that the two support plates 1 are placed stably on the ground. Then, turn the handwheel 9 at one end of the double-acting screw 8 to drive the threaded bushing 10 on the double-acting screw 8 to move, which in turn drives the connecting rod 11 to push the movable plate 4 downward. The movable plate 4 drives the hinged foot support rods 5 on both sides to rotate downward and unfold. The tension spring 6 stretches to maintain the unfolded state of the foot support rods 5. The foot support rods 5 gradually contact the ground and provide support. During the process, the rollers 12 at the end of the side plate 7 assist the foot support rods 5 to rotate smoothly until the desired stable support state is achieved. At the same time, when the movable plate 4 moves downward, it can drive the sleeve 15 to move downward and contact the ground, thus fixing the position of the entire guardrail 2. Conversely, if you want to retract the foot support rods 5, simply turn the handwheel 9 in the opposite direction to move the movable plate 4 upward. The foot support rods 5 will retract and return to their original position under the action of the tension spring 6 and their own weight.
