Road and bridge construction fence

Abstract

The invention discloses a road and bridge construction fence. When the two fences are connected, a fan-shaped hollow rotor is driven to make deflexion by friction force so as to push a rotating blocking piece to rotate, so that the two connected fences communicate with each other. The road and bridge construction fence is characterized in that a sealing sliding strip is arranged at the lower partof one side of a fence shell, and a rotor fixing groove is formed in one side of the fence shell and is located under the sealing sliding strip; a fixed block sliding groove is formed in the lower part of one side of the fence shell and is located on one side of the sealing sliding strip, and the hollow rotor is arranged in the rotor fixing groove and is connected with the fence shell through a pin; the hollow rotor is of a fan-shaped blocky structure with the central angle being 90 degrees, the outer side arc-shaped surface of the hollow rotor is of an open structure, and the radius of the hollow rotor is equal to the width of the rotor fixing groove; and one end of a fixing rod is arranged on the hollow rotor, the other end of the fixing rod is arranged in the fence shell, one end of a transmission rod and the fixing rod are hinged, and the other end of the transmission rod and a connecting rod are hinged.

Description

Technical field [0001] The invention relates to a fence for road and bridge construction, which relates to a fence device that can be connected to each other and belongs to the field of road and bridge construction. In particular, it relates to an enclosure device capable of driving a fan-shaped hollow rotor to deflect by frictional force when connecting two enclosures, thereby pushing a rotating baffle to rotate, and connecting two connected enclosures. Background technique [0002] At present, during road and bridge construction, fences are often used to isolate the construction area. Due to the needs of construction operations, it is often necessary to carry and move the fences. It is required to have the advantages of mobility, lightness and convenience, and water injection fences are usually used.

Problems solved by technology

[0002] At present, during the construction of roads and bridges, fences are often used to isolate the construction area. Due to the needs of construction operations, it is often necessary to move the fences, which are required to have the advantages of being mobile, light and convenient, and water injection fences are usually used. When in use, arrange the water injection enclosures neatly, and inject a certain amount of water into each enclosure respectively. The enclosures after water injection are not easy to disassemble and move. It is necessary to drag the water injection pipe and water storage equipment around the enclosure circle. When releasing water, it is necessary to insert the suction pipes into each enclosure to pump water, which takes a lot of time, or directly push down the enclosure to discharge water, which consumes a lot of physical strength for the operators. And it is easy to cause damage to the fence. Publication No. CN202596257U discloses an assembled water injection fence. The fence is fixed by positioning columns. The bottom of the fence is a widened part, and the widened part is provided with a water inlet and a water outlet. The water injection space inside the enclosure is independent of each other, and the water injection operation needs to be performed separately. The water injection also needs to be handled separately. In order to prevent debris such as sand and gravel from falling into the water injection cavity, a cover is usually installed on the water inlet and outlet, and the cover is repeatedly twisted The wrists of the workers will be seriously injured, and the collision during the handling process will easily cause the cover to fall and be lost, which will affect the normal use of the enclosure
