DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0018] like Figures 1 to 4A movable road construction safety guardrail shown in the figure includes a first baffle 1, a second baffle 2 and a third baffle 3, the first baffle 1 and the third baffle 3 are respectively connected to a support rod 4, and the support rod 4 is connected to a triangular support frame 7; the first baffle 1 and the second baffle 2 are connected by a hinge, and the first baffle 1 and the second baffle 2 are respectively provided with a mounting groove 6, the first baffle 1 is rotatably connected to a limiting rod 11, and the limiting rod 11 is located on the inner side of the mounting groove 6, the second baffle 2 is connected to a card frame 12, and the card frame 12 is provided with a card slot 13, the limiting rod 11 and the card slot 13 cooperate with each other, and the limiting rod 11 can be inserted into the card slot 13, thereby limiting the rotation of the second baffle 2 relative to the first baffle 1, thereby The first baffle plate 1 and the second baffle plate 2 form a relatively fixed baffle plate, and the connection method between the second baffle plate 2 and the third baffle plate 3 is the same as the connection method between the second baffle plate 2 and the first baffle plate 1, that is, the second baffle plate 2 and the third baffle plate 3 are also rotatably connected by hinges, and structures such as the limit rod 11 are also arranged in the same manner. The hinge between the first baffle plate 1 and the second baffle plate 2 is located on the front side, and the hinge between the second baffle plate 2 and the third baffle plate 3 is located on the rear side, thereby ensuring that the first baffle plate 1, the second baffle plate 2 and the third baffle plate 3 can be stably folded. In actual use, multiple groups of second baffle plates 2 can be arranged in the same connection method to increase the protection area of ​​the guardrail, and the connection of the hinges can be arranged in a front-to-back staggered manner.

[0019] The triangular support frame 7 is connected to the cylinder 8, the output shaft of the cylinder 8 is connected to the bearing plate 15, and the bearing plate 15 is connected to the universal wheel 9; the limiting rod 11 is connected to the first magnet 14, the card frame 12 and the first baffle plate 1 are respectively connected to the second magnet 5, the first magnet 14 and the second magnet 5 attract each other, and the first baffle plate 1, the second baffle plate 2 and the third baffle plate 3 are respectively connected to the observation window 10.

[0020] The specific implementation process is as follows:

[0021] When using Figure 1 As shown, the first baffle 1, the second baffle 2 and the third baffle 3 are unfolded and arranged in parallel. At this time, the limit rod 11 is inserted into the slot 13, so that the second baffle 2 cannot rotate relative to the first baffle 1. Similarly, the third baffle 3 cannot rotate relative to the second baffle 2. The two sets of triangular support frames 7 support the guardrail as a whole. When the guardrail needs to be moved a short distance, the cylinder 8 is started to drive the load-bearing wheel to move downward, thereby grounding the universal wheel 9, and then the guardrail can be quickly pushed to move. After moving to the specified position, the universal wheel 9 can be lifted up again.

[0022] The following describes the folding of the guardrail by taking the first baffle 1 and the second baffle 2 as an example. Figure 1 and Figure 4As shown, at this time, the limit rod 11 is inserted into the slot 13, and the second baffle 2 cannot rotate relative to the first baffle 1. When folding is required, the limit rod 11 is pushed to rotate counterclockwise, so that the limit rod 11 slides out of the slot 13 and slides into the mounting slot 6 of the first baffle 1. The second magnet 5 on the first baffle 1 is attracted to the first magnet 14 so that the limit rod 11 can be stably received in the mounting slot 6 of the first baffle 1. At this time, the limit rod 11 no longer plays a limiting role, and the second baffle 2 can be rotated clockwise (forward) relative to the first limit plate to complete the folding; similarly, the folding of other baffles can be completed in sequence; when unfolding is required, the universal wheel 9 is grounded, and then the first baffle 1 is directly immobilized, and the guardrail can be unfolded by directly pulling the third baffle 3.

[0023] The technical solution uses hinges to connect multiple baffles, which is convenient for quickly folding multiple baffles, saving storage space and facilitating the storage and transportation of the guardrail. At the same time, it can be quickly unfolded and is easy to install. The limit rod 11 and the card frame 12 can be used to limit the position of two adjacent baffles to prevent them from rotating at will. The limit rod 11 can be directly rotated to release the limit and complete the folding. The structure is simple and easy to operate. The installation groove 6 allows the two adjacent baffles to be folded together as much as possible, avoiding the limit rod 11 affecting the folding between the baffles, improving the folding effect and quality, and greatly improving the practicality. The triangular support frame 7 supports the guardrail as a whole, improves the stability of use, and the subsequent The positioning plate and the universal wheel 9 can be driven downward by the cylinder 8, and the guardrail can be quickly moved without folding the baffle, which is convenient for quickly adjusting the use position and improving the applicability of the guardrail. The universal wheel 9 does not need to be grounded during normal use, which improves the placement stability of the guardrail and avoids damage to the universal wheel 9 due to long-term grounding. The limiting rod 11 can be stably inserted into the card slot 13 due to the attraction between the first magnet 14 and the second magnet 5, thereby improving the limiting stability. The baffle can also be stably stored in the installation slot 6 when folded, which is easy to use. The observation window 10 is convenient for people on the outside to observe the construction situation inside the guardrail, which is convenient for relevant staff to carry out inspection work and improves the applicability of the guardrail.
