Description

Technical Field

[0001] The utility model relates to the field of construction protection related products, in particular to a protection device for rail transit construction. Background Art

[0002] During rail transit construction, in order to ensure the safety of the construction area, guardrails are installed around some special construction areas. On the one hand, the guardrails serve as a reminder to prevent non-construction personnel from mistakenly entering the construction area and causing danger; on the other hand, they can provide a barrier to prevent people or construction vehicles from falling. In order to improve adaptability, the warning words on the guardrails are mainly safety tips or warning information, aiming to remind people to pay attention to potential dangers and follow safety regulations or recommendations to prevent accidents.

[0003] However, the warning signs on the existing guardrails are mostly pre-set by spray painting. Replacing the warning signs for different application scenarios requires replacing different guardrails together, which is relatively cumbersome. Utility Model Content

[0005] The top of described sliding panel also is provided with an interlock plate, and the interlock plate is hinged on the base plate, is fixed with a backing pin on the interlock plate, and an end of sliding panel withstands on the backing pin of interlock plate.

[0006] Preferably, one end of the connecting plate on one side is fixedly connected to the traction sleeve, and one end of the connecting plate on the other side is fixedly connected to the hook.

[0007] Preferably, a foot plate is fixedly connected to the bottom of the support plate.

[0008] Preferably, the transparent plate is a transparent acrylic plate.

[0009] Preferably, the number of the plurality of hinges is not less than two.

[0010] Preferably, the bottom of the support plate is provided with a plurality of anti-slip grooves arranged in an inclined manner.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The protective device for rail transit construction is installed and fixed between the support plates on both sides and the guardrail body by connecting plates, and the support plates are used to support the guardrail body. The printed warning sticker can be placed in the positioning frame in the installation box, and then the transparent plate is flipped around the installation box by hinges. At this time, the card frame on the inner wall of the transparent plate is clamped in the positioning frame to press the warning sticker, and the transparent plate is fixed by screwing the locking bolt on the positioning block into the screw groove in the positioning groove. The utility model can replace the warning wording of the guardrail according to different construction methods without replacing a new guardrail. The operation is simple and convenient.
