Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of mold frame technology, specifically relating to a mold frame for manufacturing small pile core steel cages. Background Technology
[0002] In traditional wind power foundation construction, precast PHC pile foundations are typically used, with the pile cores constructed using a small steel cage cast-in-place process. However, due to the small diameter of the small steel cages, the processing platform cannot fully meet the processing requirements. Therefore, the production efficiency of the steel cages is particularly important to meet the on-site construction schedule.
[0003] In existing technologies, equipment used for fabricating small pile core reinforcement cages suffers from shortcomings in terms of support and transportation, making it difficult to move them conveniently between different work sites, thus increasing the complexity and cost of construction. In actual construction, the dimensions and specifications of the reinforcement cages used in the same project vary, and molds with a single structure often cannot meet the actual needs. Moreover, the removal process after the reinforcement cage is fabricated is cumbersome and consumes a significant amount of time and manpower. Therefore, those skilled in the art have provided a small pile core reinforcement cage fabrication formwork to solve the problems mentioned in the background art. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this utility model provides a small-scale pile core steel cage fabrication formwork to solve the problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a small pile core rebar cage fabrication formwork frame, comprising a circular steel plate and a triangular bracket. The triangular bracket is fixedly installed on the side of the circular steel plate, and the triangular bracket can fix the height of the circular steel plate and provide support stability. An inner ring positioning sleeve is installed on the front side of the circular steel plate, and an outer ring positioning sleeve is provided around the inner ring positioning sleeve. A caster wheel is installed on the bottom side of the triangular bracket. A push plate is provided on the side of the circular steel plate away from the inner ring positioning sleeve. A push rod is installed on the side of the push plate facing the circular steel plate. A screw hole is opened in the middle of the push plate, and a screw rod is provided in the screw hole. A snap-fit component is installed at one end of the screw rod. A snap-fit hole is opened in the middle of the circular steel plate.
[0006] Furthermore, the inner ring positioning sleeve and the outer ring positioning sleeve are in communication with the circular steel plate, and one end of the push rod is inserted into the corresponding inner ring positioning sleeve or outer ring positioning sleeve.
[0007] Furthermore, the screw is rotatably engaged with the snap-fit hole on the circular steel plate via a snap-fit component, and the screw is threadedly engaged with the push plate via a screw hole.
[0008] Furthermore, a turntable is installed at one end of the screw. By rotating the screw through the turntable, the push plate drives the push rod to squeeze into the inner ring positioning sleeve and the outer ring positioning sleeve, thereby pushing the processed small steel cage out of the inner ring positioning sleeve and the outer ring positioning sleeve, and completing the separation. Beneficial effects
[0009] The design incorporates a triangular bracket that provides stable support for the circular steel plate. Casters are installed at the bottom of the triangular bracket to enhance portability and facilitate transfer between different work sites. Inner and outer ring positioning sleeves are installed on one side of the circular steel plate. During use, the processed reinforcing bars are vertically inserted into the corresponding sleeves to achieve positioning and processing of small reinforcing cages. This design is applicable to various specifications. A push plate is installed on the side of the circular steel plate away from the inner ring positioning sleeve. Push rods, the same number and position as the positioning sleeves, are installed on the push plate. The front end of each push rod is inserted into the corresponding sleeve. A snap-fit hole is opened in the middle of the circular steel plate, and a threaded hole is opened in the middle of the push plate to thread a screw rod. A snap-fit device is installed at one end of the screw rod to rotate and snap into the circular steel plate. After the small reinforcing cage is processed, rotating the turntable causes the screw rod to rotate, and the push plate drives the push rod to press into the positioning sleeve, easily pushing the processed small reinforcing cage out of the positioning sleeve for rapid separation.
