Prefabricated square culvert carrying device

Abstract

The invention relates to a prefabricated square culvert carrying device which comprises a first carrying mechanism and a second carrying mechanism, and the second carrying mechanism is arranged on one side of the first carrying mechanism and used for bearing a square culvert on the first carrying mechanism; the first carrying mechanism comprises two symmetrically-arranged first overturning assemblies, and the second carrying mechanism is located between two first overturning assemblies. The first overturning assembly comprises a first bracket, and the first bracket comprises two vertically-arranged first connecting rods; a first support is hinged to the corner of the first bracket, first telescopic rods are hinged to the middles of the outer sides of the two first connecting rods, and second supports are hinged to the ends, away from the first bracket, of the first telescopic rods; the second carrying mechanism comprises two second overturning assemblies which are symmetrically arranged, each second overturning assembly comprises a second bracket, and each second bracket comprises two second connecting rods which are vertically arranged and connected, so that the second brackets form an L shape; a third support is hinged to the corner of the second bracket, second telescopic rods are hinged to the middles of the outer sides of the two second connecting rods, and the ends, away from the second bracket, of the second telescopic rods are hinged to fourth supports.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a prefabricated square culvert handling device. Background technique [0002] The laying of underground pipelines is very important in urban planning, and square culverts are often used in the construction of municipal facilities such as urban underground comprehensive pipelines and power tunnels. Prefabricated square culvert is a box-shaped pipe culvert prefabricated in the factory by using high-strength reinforced concrete. It is composed of multiple square or rectangular sections, hence the name square culvert. The production process is generally to pour concrete between the inner mold and the outer mold of the mold, and take out the mold after the concrete is formed, so the square culvert is generally set with the mouth facing upwards after forming. Square culverts often need to be transported to the construction site after being formed. When using, choose to turn the sq...

Problems solved by technology

Square culverts often need to be transported to the construction site after being formed. When using, choose to turn the square culvert 90° or 180° according to the needs and then directly transport it away with a forklift to meet the construction requirements; however, due to the large size and weight of the formed square culvert , it is difficult to realize its flipping in actual handling, which will lead to a decrease in laying efficiency
