Description

Technical Field

[0001] The utility model relates to the technical field of enclosures, in particular to a road construction protective enclosure. Background Art

[0002] Fences are barriers used to surround and block construction areas on highways, reminding pedestrians and drivers to take detours and preventing them from entering construction sites on highways. In order to prevent non-staff from entering the construction site and causing danger during road construction, protective fences are generally built around the construction site. Currently, during road construction, there are situations where construction is only carried out on parts of the road. When the road is under construction, the construction area will be enclosed by fences, and then other areas of the road will be used normally. However, the existing fences are all set up separately, and staff need to install and build them before use, which is time-consuming and labor-intensive, and greatly affects construction efficiency.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] like Figures 1 to 3As shown, a road construction protection fence includes four L-shaped pillars 1 arranged corresponding to each other, and four scissor-type enclosure frames 2, the upper end of the L-shaped pillar 1 is provided with a pulling handle 16, and both sides of the L-shaped pillar 1 are provided with a storage groove 3. The outer wall of the L-shaped pillar 1 is provided with at least one ladder plate 17, and the bottom surface of the L-shaped pillar 1 is provided with a telescopic groove 18, and an electric push rod 13 is fixedly connected in the telescopic groove 18. The lower end of the electric push rod 13 is fixedly connected to a mounting plate 14, and the bottom surface of the mounting plate 14 is provided with a moving wheel 15.

[0020] The lower end of the storage groove 3 is fixedly connected to a fixed shaft 5, and the storage groove 3 is slidably connected to a parallel movable shaft 4 above the fixed shaft 5. Both sides of the storage groove 3 are provided with sliding holes 6 that cooperate with the movable shaft 4. The scissor-type enclosure frame 2 is located between the storage grooves 3 on the opposite sides, and the four corners of the scissor-type enclosure frame 2 are respectively hinged to the corresponding movable shaft 4 and the fixed shaft 5.

[0021] The two ends of the L-shaped pillar 1 are respectively provided with a fixed plug plate 7 and a fixed slot 11, and both sides of the fixed plug plate 7 are provided with movable slots 10, and the movable slots 10 are slidably inserted with fixed blocks 8, and the cross-section of the fixed block 8 is a right-angled trapezoid. The movable slot 10 is provided with a fixing spring 9 that cooperates with the fixed block 8, and both sides of the fixed slot 11 are provided with fixed sockets 12 that cooperate with the fixed block 8.

[0022] In specific use, the device is not in use. Figure 4 As shown, four L-shaped pillars 1 are connected end to end to form a hollow rectangular column, which occupies a small space. It can be pulled to move by pulling the handle 16 and the moving wheel 15. When the construction site needs to be fenced, before construction, the device is pulled to the center of the construction site, and the fixing blocks 8 on both sides of the L-shaped column are pressed to make the fixing blocks 8 go deep into the fixing slots 11, squeezing the fixing springs 9 to cause compression deformation, and pulling the four L-shaped columns away from each other, so that the fixing plug plates 7 extend out of the fixing slots 11, and the L-shaped columns drive the scissor-type enclosure frame 2 to extend, and the corresponding movable shafts 4 at both ends of the scissor-type enclosure frame 2 slide downward along the sliding holes 6 to complete the construction of the enclosure, and the electric push rods 13 at the four corners are started to pull the moving wheels 15 into the telescopic slots 18 to prevent the enclosure from moving, and the staff can enter and exit through the ladder board 17.
