Detailed Description
The utility model will be further described with reference to the drawings and the specific examples.
Referring to fig. 1 to 5, an anti-roll-over construction fence comprises a fence plate 1, a lifting plate 2 and a limiting assembly.
Specifically, the top surface of the fence board 1 is provided with a lifting chute 3 for lifting the lifting board 2; the lifting plates 2 are arranged in two, the lifting plates 2 are arranged in the lifting sliding chute 3 in parallel, the gear plates 4 are arranged on the inner sides of the opposite sides of the lifting plates 2, a transmission gear column 5 is rotatably arranged between the two gear plates 4, and the transmission gear column 5 is rotatably arranged on the inner wall of the lifting sliding chute 3; the limiting assembly is arranged on one of the lifting plates 2, and when the limiting assembly is triggered, the lifting plate 2 is at the current height.
In the present embodiment, the top of the lifter plate 2 is flush with the bottom. When the height of the fence needs to be adjusted, one lifting plate 2 is pressed downwards, the driving gear column 5 is driven to rotate through the gear plate 4 in the descending process of the lifting plate 2, meanwhile, the driving gear column 5 drives the other lifting plate 2 to ascend through the other gear plate 4, and when the lifting plate 2 ascends to a certain height, the limiting component limits the lifting plate 2, and the lifted lifting plate 2 is stably positioned at the height.
In order to enable a fence layout around a construction site, the fence panel 1 is provided with a plurality of fence panels, and a plurality of fence panels 1 are detachably connected.
In a specific embodiment, the fence board 1 is provided with a connecting slot 6 and a connecting block 7 on two sides along the arrangement length thereof, and the connecting slot 6 is rotatably connected with the connecting block 7 through a pin shaft. The number of the fence boards 1 can be determined according to the size of a field, and the adjacent fence boards 1 are connected and installed by utilizing the pin shafts, so that the operation on the field is convenient.
Further, a positioning groove 8 is formed in the inner wall of the lifting chute 3 along the height direction of the lifting chute, a positioning block 9 is slidably arranged in the positioning groove 8, and the positioning block 9 is fixedly connected with the lifting plate 2.
Specifically, in order to ensure that the lifting plate 2 can stably lift in the lifting chute 3, a positioning block 9 is arranged in the lifting chute 3, and the positioning block 9 slides in the lifting chute 3 to position the lifting plate 2.
Further, the limiting component comprises a mounting groove 10 arranged on the side face of the lifting plate 2, a limiting block 12 is elastically mounted in the mounting groove 10 through a limiting spring 11, and a limiting groove 13 matched with the limiting block 12 is formed in the inner wall of the lifting sliding groove 3.
