Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically a temporary guardrail for road and bridge construction. Background Technology

[0002] Road and bridge engineering refers to the surveying, design, construction, maintenance, and management of highways and bridges. To prevent unauthorized personnel from entering the construction site, guardrails are used to protect the construction area during the construction process, so that construction workers can carry out their work more effectively.

[0003] While guardrails are convenient for protecting construction sites, they inevitably have shortcomings in actual use. One such shortcoming is the lack of a rapid enclosure mechanism, which leads to cumbersome enclosure operations due to the reliance on splicing guardrails together to protect the construction site. Therefore, a temporary guardrail for road and bridge construction is proposed to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a temporary protective barrier for road and bridge construction, which solves the problem of cumbersome barrier maintenance operations due to the lack of a rapid enclosure mechanism.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a temporary guardrail for road and bridge construction, including an I-shaped movable frame, wherein a plurality of I-shaped movable frames are provided, and a rotating rod is rotatably provided between the top and bottom of the inner cavity of the I-shaped movable frame, and two rotating rods are symmetrically provided, and a guardrail plate is fixedly connected between two adjacent rotating rods.

[0006] The guardrail panel has slots on both sides of its top. The I-shaped movable frame has folded edge slots on both sides of its top front side that match the slots. The I-shaped movable frame also has straight edge slots on both sides of its top that match the slots. A threaded rod is rotatably mounted on the top of the I-shaped movable frame. A threaded sleeve is threadedly connected to the surface of the threaded rod. A first insert is fixedly connected to the bottom of the threaded sleeve that matches the folded edge slots and slots. A second insert is fixedly connected to the rear side of the first insert that matches the straight edge slots and slots.

[0007] Preferably, the front side of the I-shaped movable frame is provided with a storage groove, and a rotating shaft is rotatably arranged between the two sides of the inner cavity of the storage groove. A gear is fixedly connected to the surface of the rotating shaft, and a reinforcing plate is fixedly connected to the surface of the rotating shaft and on both sides of the gear.

[0008] The bottom of the second insert is fixedly connected to a linkage rod, the bottom end of which extends into the interior of the storage slot, and the end of the linkage rod extending into the storage slot is fixedly connected to a toothed plate that meshes with a gear.

[0009] Preferably, the bottom of the I-shaped movable frame is provided with pulleys.

[0010] Beneficial effects

[0011] This utility model provides a temporary protective barrier for road and bridge construction. Compared with existing technologies, it has the following advantages: This utility model assembles a protective barrier by combining several I-shaped movable frames, rotating rods, and guardrail panels, making the device easy to fold and unfold. This facilitates daily storage and loading, as well as manual dragging on the construction site. It allows the device to be moved while unfolding for enclosure, simplifying the enclosure process and improving enclosure efficiency. Secondly, slots, straight edge grooves, folded edge grooves, a first insert, and a second insert are provided between the guardrail panels and the I-shaped movable frames. This allows the I-shaped movable frames to integrally limit the 90-degree and 180-degree rotation of the guardrail panels through the above-mentioned cooperation, improving the overall stability of the device. Furthermore, a reinforcing plate is provided inside the I-shaped movable frames, allowing the device to drive the reinforcing plate to support and reinforce the ground while simultaneously engaging the above-mentioned limiting cooperation.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-9 This utility model provides a technical solution: a temporary guardrail for road and bridge construction, including an I-shaped movable frame 1, with a plurality of I-shaped movable frames 1, a rotating rod 2 rotatably arranged between the top and bottom of the inner cavity of the I-shaped movable frame 1, and two rotating rods 2 are symmetrically arranged, with guardrail plates 3 fixedly connected between two adjacent rotating rods 2, and pulleys are provided at the bottom of the I-shaped movable frame 1.

[0024] Furthermore, to facilitate rapid enclosure of the construction site and integrated positioning of the device, slots 14 are provided on both sides of the top of the guardrail 3, and folded edge slots 41 matching the slots 14 are provided on both sides of the front top of the I-shaped movable frame 1. Straight edge slots 42 matching the slots 14 are provided on both sides of the top of the I-shaped movable frame 1. A threaded rod 5 is rotatably provided on the top of the I-shaped movable frame 1. A threaded sleeve 6 is threadedly connected to the surface of the threaded rod 5. A first insert 71 matching the folded edge slots 41 and slots 14 is fixedly connected to the bottom of the threaded sleeve 6. A second insert 72 matching the straight edge slots 42 and slots 14 is fixedly connected to the rear side of the first insert 71.

[0025] Furthermore, to facilitate the establishment of a reinforced support between the device and the ground after it is deployed, a storage slot 9 is provided on the front side of the I-shaped movable frame 1. A rotating shaft 11 is rotatably arranged between the two sides of the inner cavity of the storage slot 9. A gear 12 is fixedly connected to the surface of the rotating shaft 11, and a reinforcing plate 13 is fixedly connected to the surface of the rotating shaft 11 and on both sides of the gear 12.

[0026] The bottom of the second insert 72 is fixedly connected to a linkage rod 10. The bottom end of the linkage rod 10 extends into the interior of the storage slot 9. One end of the linkage rod 10 extending into the interior of the storage slot 9 is fixedly connected to a toothed plate 15 that meshes with the gear 12.

[0027] In use, the folded device is moved to the construction site by rollers, and then gradually unfolded along the construction route. After several I-shaped movable frames 1 and guardrail plates 3 are unfolded to form a rectangle around the construction site, several threaded rods 5 are screwed in sequence. The threaded rods 5 screw on the threaded sleeves 6, which causes the first insert 71, the second insert 72 and the toothed plate 15 to descend. The first insert 71 and the second insert 72 descend and pass through the corresponding folded edge slots 41 and straight edge slots 42 until they enter the slot 14, thereby positioning the unfolded guardrail plates 3 as a whole. The second insert 72 simultaneously drives the toothed plate 15 to mesh with the gear 12. When the device is in the limit position, the toothed plate 15 will mesh with the gear 12, causing the top of the reinforcing plate 13 to rotate to the ground, thereby forming a reinforcing support between the ground and the I-shaped movable frames 1.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
