Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to a steel cage hoisting positioning guide frame device. Background Art

[0002] The main function of the steel cage is the same as that of the longitudinal steel bars of the column, mainly playing a tensile role. The compressive strength of concrete is high, but its tensile strength is very low; it plays a role in restraining the concrete of the pile body so that it can bear a certain axial tensile force; during the construction of bridges, culverts or high-rise buildings, according to requirements, piling of the foundation may be required. The method is to use a machine to punch holes and grind holes with water, and the hole depth reaches the design requirements. Then, a steel cage is lowered into the pile hole, and a conduit is inserted for concrete pouring; in addition, when the concrete structure is a columnar or strip-shaped member, no steel bars are required in the central part, and steel bars are only arranged under the surface of the concrete member in contact with the air; if this member is independent, the steel bars arranged around this member are prefabricated in advance, and this is the steel cage; usually, the prefabricated steel structures such as bored cast-in-place piles, dug piles, and columns are called steel cages;

[0003] Application No. 201822025709.3 provides a steel cage hoisting positioning guide frame device. The leveling cross tube is connected to the hook of the crane, and the bottom of the guide tube is inserted into the steel cage, so that the connecting hook hooks the first reinforcing stirrup of the steel cage. The lifting hook drives the guide tube through the leveling cross tube and then drives the steel cage to be hoisted. Subsequently, after the steel cage is moved above the cast-in-place pile, the hook is controlled to insert the steel cage into the cast-in-place pile. A fixing rod is arranged at the edge of the hole of the cast-in-place pile. When the steel cage is placed on the hole opening, the fixing rod is fixedly connected to the fixing tube by bolts. The leveling cross tube is placed on the top of the longitudinal bars of the steel cage, and the steel cage is finely leveled through the leveling bubble. Subsequently, concrete is poured. After the pouring is completed, the leveling cross tube is removed, and the guide tube is taken out and washed;

[0004] However, when the device hooks the steel cage and inserts it into the cast-in-place pile, the shaking generated by the hook of the crane will be transmitted to the towing rope, resulting in the shaking of the steel cage and affecting the stability of the installation and insertion. It requires the staff to support and position the installation; but if the towing rope is not used for hoisting, it is inconvenient to operate when installing the connecting hook, and the practicability is poor.

[0029] Working principle: All the electrical components appearing in this application are externally connected to a power supply and a control switch during use. After this utility model is installed, first check the installation, fixation, and safety protection of this utility model, and then it can be used. When in use, hang the hook of the crane on the leveling crossbar 15, and then connect the connecting hook 8 to the steel reinforcement cage, so that the crane lifts the steel reinforcement cage. After lifting the steel reinforcement cage, start the motor 13, so that the motor 13 drives the second rotating shaft 10 to rotate.
