Description

Technical Field

[0001] The utility model relates to the technical field of road guardrails, in particular to a reinforced mobile guardrail. Background Art

[0002] The guardrail in the middle of the road is a passive safety protection facility used to prevent accidents, while the isolation facility is the last barrier separating motor vehicles from non-motor vehicles. If a vehicle collides with or passes through the isolation facility in the event of an accident, it will directly threaten the lives of workers in the construction area.

[0003] Most traditional mobile guardrails are completely fixed on the ground. Therefore, when a vehicle hits the guardrail, the guardrail is not easy to unload the force on the vehicle, and the guiding effect on the vehicle is poor. Therefore, the vehicle can easily rush through the guardrail directly, increasing the severity of the accident. Utility Model Content

[0006] The reinforced movable guardrail comprises a plurality of fixed unit sections and a plurality of movable unit sections, wherein the plurality of movable unit sections are distributed between the plurality of fixed unit sections;

[0007] The fixed unit section and the mobile unit section both include a bottom frame and a bottom plate arranged below the bottom frame, an interception portion is arranged above the bottom frame, the bottom plate included in the fixed unit section is fixed to the ground by pins, the bottom of the bottom plate included in the mobile unit section is fixedly connected to a plurality of sliding devices, the bottom of the sliding device is in contact with the ground, and a connecting portion is arranged between the bottom plate and the bottom frame.

[0008] Furthermore, the connecting portion includes a plurality of bottom grooves opened at the bottom of the bottom plate, a bolt 1 is passed through the bottom groove, a portion of the bolt extends into the corresponding bottom frame, and the bolt 1 is threadedly connected to the bottom frame, and the bottom surface of the bolt 1 is higher than the bottom surface of the corresponding bottom plate.

[0009] Furthermore, the intercepting portion includes a plurality of columns fixedly connected to the top of the bottom frame, and a crossbeam is fixedly connected to the tops of the corresponding plurality of columns, and two adjacent crossbeams are connected via a fixing unit.

[0010] Furthermore, the fixing unit includes a square groove opened at one end of the beam, and a square block is fixedly connected to the other end of the beam. The square block is inserted into the corresponding square groove, and each side wall of the square block is in contact with the inner wall of the square groove.

Two bolts are passed through the two through holes and the mounting opening, and the block is fixedly connected to the square groove by two bolts and a nut.

[0011] Furthermore, a plurality of horizontal reinforcing rods are fixedly connected inside the bottom frame.

[0012] In summary, the present invention includes at least one of the following beneficial technical effects:

[0013] 1. The reinforced mobile guardrail has a small friction force between the mobile unit section and the ground under the action of the sliding device. Therefore, when a vehicle impacts the mobile unit section, the mobile unit section can move sideways to a certain extent, unloading the lateral impact force of the vehicle and converting the impact force into a force in the direction of the vehicle's travel, thereby preventing the vehicle from rushing straight through the guardrail and causing secondary safety accidents;
