Description

Technical Field

[0001] The invention relates to the technical field of container hoisting, in particular to material hoisting equipment for civil engineering construction. Background Art

[0002] Because water transportation has the advantages of large transportation volume, low cost and long transportation distance, some civil engineering construction materials are usually transported by water containers and then unloaded at nearby ports.

[0003] Although material lifting in civil engineering construction also involves container transportation, it is essentially different from port operations. The construction materials required for civil engineering are rich and varied, ranging from large and irregularly shaped precast concrete beams, complex steel structures, to granular sand and gravel, bagged cement, etc. Even if they are loaded into containers for transportation, they still bring many challenges to lifting. These construction materials vary significantly in weight and appearance, making it difficult to unify the size and specifications of containers in civil engineering. To this end, the present invention provides a material lifting equipment for civil engineering construction. Summary of the invention

[0004] The purpose of the present invention is to provide a material lifting equipment for civil engineering construction to solve the problems raised in the above background technology.

[0006] Preferably, the bottom of the mounting outer frame is fixedly connected to an outer clamping plate, the bottom of the outer clamping plate is fixedly connected to a clamping mounting plate, the bottom of the clamping mounting plate is fixedly connected to a supporting bottom plate, the outer clamping plate is slidably clamped with four support clamping columns, both ends of the support clamping column are fixedly connected to protective side blocks, the support clamping column and the clamping mounting plate are fixedly connected to four telescopic push cylinders at both ends, a telescopic spring is installed inside the telescopic push cylinder, the support clamping column is fixedly connected to an inner adjustment block on one side adjacent to the clamping mounting plate, one side of the inner adjustment block is fixedly connected to an inner adjustment shaft, the bottom of the limit inner plate column is fixedly connected to a limiting length block, the top of the limiting length block is fixedly connected to a trapezoidal push block, the top oblique surface of the trapezoidal push block is inclined to the clamping mounting plate, and the limiting length block is located at the inner adjustment shaft Bottom; when in use: the container is clamped by the outer clamping plate, and when the outer clamping plate is upward, the limited inner plate column will not move upward due to the lifting and clamping box limit, and the outer clamping plate will move upward along the limited inner plate column. When the trapezoidal pushing block at the bottom of the limited inner plate column passes over the top inner adjustment axis, the support clamping column will be pushed by the telescopic spring and move to the bottom of the container. If the first support clamping column is still located on the side, the support clamping column will be blocked, and the outer clamping plate will continue to move upward, which will push out the remaining support clamping columns at the bottom one by one, so that the support clamping columns enter the bottom of the container for support and prevent slipping. When lowering, the trapezoidal pushing block will push the inner adjustment axis to move the clamping installation plate from the bottom to retract the support clamping column, and then lower the container. This structure can also avoid the bottom support lifting when the upward clamping force of the outer clamping plate is insufficient.

[0008] First, the material hoisting equipment for civil engineering construction described in the present invention controls the up and down movement of the movable top plate by starting the lifting electric cylinder, and the limit movable plate is always at the same height. When the movable top plate moves upward, it will drive the movable top roller to move upward, and drive the connecting rotating plate to move upward. Because one end of the connecting rotating plate is connected to the limit movable plate, the connecting rotating plate will gradually rotate, so that the bottom ends of the two connecting rotating plates will gradually approach each other, so that the two limit movable plates will gradually approach each other, and so that the two installation outer frames will gradually approach each other to clamp the container. When the clamping is completed, the movable top plate will continue to rise, because the container has been clamped, it will continue to pull the installation outer frame upward, so that the container continues to move upward and break away from the support.

[0009] When the container is lowered, the trapezoidal push block will push the inner adjustment shaft to move the clamping mounting plate from the bottom to the bottom, so that the support clamping column can be retracted and the container can be lowered. This structure can also prevent the bottom support from being lifted when the upward clamping force of the outer clamping plate is insufficient.

[0010] Summary: The material lifting equipment for civil engineering construction described in the present invention realizes rapid clamping and stable support of containers through a specific mechanical structure, avoiding problems such as shaking and slipping that may occur in traditional lifting methods. At the same time, the equipment also has good adaptability and flexibility, and can adapt to containers of different sizes and specifications to meet the diverse needs in civil engineering construction.

When the movable top plate 5 moves upward, it will drive the movable top roller 6 to move upward, and drive the connecting rotating plate 7 to move upward. Because one end of the connecting rotating plate 7 is connected to the limited movable plate 9, the connecting rotating plate 7 will gradually rotate, so that the bottom ends of the two connecting rotating plates 7 are gradually close to each other, so that the two limited movable plates 9 are gradually close to each other, so that the two installing outer frames 16 are gradually close to each other, and the container is clamped. When the clamping is completed, the movable top plate 5 will continue to rise, because the container has been clamped, the installing outer frame 16 will continue to be pulled upward, so that the container continues to move upward and break away from the support.
