Automatic butt-joint positioning and cutting-off structure for concrete pile head

Abstract

The invention discloses an automatic butt-joint positioning and cutting-off structure for a concrete pile head. The automatic butt-joint positioning and cutting structure for the concrete pile head comprises a lifting appliance (1) and a hanging ring (4) and is characterized in that the lower end of the hanging ring (4) is fixed to the small opening end of a positioning conical cylinder (6), a fixing ring (7) is fixed to the lower portion of the large opening end of the positioning conical cylinder (6), a connecting piece (5) is fixed in the hanging ring (4), the lower end of the connecting piece (5) is located on the axial lead of the positioning conical cylinder (6) and connected with the top end of a vertical supporting rod (8) through a ball-head-shaped hinge shaft, the bottom of the fixing ring (7) is fixed to the upper end of a vertical fixing arm (12), a lifting mechanism is installed at the lower end of the vertical fixing arm (12), and the lifting connecting end of the lifting mechanism is connected with a cutting, stripping and chiseling-away assembly. The structure is reasonable, automatic butt joint positioning can be achieved, the position of a broken cut-off surface can be accurately controlled, the situation that the cut-off length is too large or insufficient is avoided, and the construction efficiency is greatly improved.

Description

technical field [0001] The invention relates to a docking positioning and truncation structure, in particular to an automatic butt joint positioning and truncation structure of a concrete pile head, which belongs to the technical field of construction engineering equipment. Background technique [0002] Bored pile is a common pile type widely used in building foundation construction, and it is widely used in various foundation constructions such as industrial and civil buildings and bridges. In order to ensure the quality of the pile head concrete of the cast-in-place pile, the code stipulates that when the bored pile is constructed, the height of the cast-in-place pile should be 500 mm to 1000 mm higher than the design height. Concrete pile heads. It is difficult to break and cut off the concrete pile head. Because it is a concrete cast-in-place structure, there are criss-cross steel bars inside the concrete pile head, which is limited by the size of the space. At the same...

Problems solved by technology

[0003] The purpose of the present invention is to solve the difficulty in docking and positioning of existing concrete pile heads before they are broken and cut off. It is difficult for equipment to be accurately inserted into the concrete pile head, which is prone to deviation, and it is difficult to control the position of the broken cut-off surface. It is very easy to lead to the situation that the truncated length is too large or insufficient. At the same time, the quality of the overall stripping chisel is not good, and the truncated surface is irregular, which seriously affects the subsequent construction progress and construction quality. Defects and deficiencies provide a reasonable structure that can realize automatic Butt positioning, and can accurately control the position of the broken sectional surface, avoiding the situation of excessive or insufficient truncated length, the construction efficiency has been greatly improved, and the overall stripping chisel quality is good, the sectional surface is regular, and there will be no damage to the broken surface. A concrete pile head automatic docking positioning and truncation structure for damage caused by the lower part of the concrete pile head
