Definitions

  • the invention relates to a hole forming device, which is used for hole formation in the construction process in the construction field.
  • the traditional hole formation is where water is injected into the place to be punched, and the wall needs to be protected and then drilled. This method is because water and mud are mixed and the hole is prone to collapse.
  • One of the problems that needs to be solved is transportation. The slurry must be transported out. During transportation, it is easy to spill and is not good for environmental protection. The second is that during the drilling process, more equipment is needed, so more labor and material resources are generated during the construction process. As a result, the production cost of the enterprise has increased.
  • the present invention provides a hole-forming device.
  • the technical solution of the present invention is:
  • a hole forming device includes a protective cylinder, a hydraulic cylinder bracket is installed on an upper port of the protective cylinder, a hydraulic cylinder is installed on the hydraulic cylinder bracket, and a piston rod of the hydraulic cylinder is directed to a lower port of the protective cylinder.
  • a bearing is installed at the end of the piston rod, at least one swing rod is hinged on the outer ring of the bearing, the other end of the swing rod is hinged on one side of the guide block, and a pressure rod is installed on the bottom of the guide block.
  • the pressure bar is arranged in the vertical direction, and a soil plate is installed at the bottom end of the pressure bar. The soil plate is perpendicular to the pressure bar.
  • a guide groove is provided on the inner wall of the protective cylinder, and the guide groove is wavy. It is arranged in a shape like a guide guide block to slide on the inner wall of the protective cylinder, so as to drive the soil compactor plate to move in the circumferential direction of the protective sheath to achieve soil compaction to form holes.
  • the lower end surface of the soil plate is an inclined surface, and it rises from the center to the outer wall of the protective cylinder.
  • the advantages of the present invention are: dry pressing is used, during the pressing process, there is no mud production, there is no transportation problem, and less equipment is needed, which reduces the cost of the enterprise.
  • FIG. 1 is a schematic diagram of the main structure of the present invention.
  • the present invention relates to a hole-forming device, including a protective cylinder 1, a hydraulic cylinder bracket 2 is installed at an upper port of the protective cylinder 1, and a hydraulic cylinder 3 is installed on the hydraulic cylinder bracket 2.
  • the hydraulic cylinder 3 The piston rod 4 is directed to the lower port of the protective cylinder 1, and a bearing 5 is installed at the end of the piston rod 4.
  • At least one swing rod 6 is hinged on the outer ring of the bearing 5, and the other end of the swing rod 6 Hinged on one side of the guide block 7, a pressure bar 8 is installed at the bottom of the guide block 7, the pressure bar 8 is arranged in a vertical direction, and a soil plate 9 is installed at the bottom end of the pressure bar 8.
  • the soil pressure plate 9 is arranged perpendicular to the pressure rod 8, and a guide groove is provided on the inner wall of the protective cylinder 1.
  • the guide groove is provided in a wave shape, and the guide block is guided to slide on the inner wall of the protective cylinder 1 to drive the soil pressure plate 9. It moves inside the sheath in the circumferential direction of the sheath to achieve soil compaction.
  • a plurality of pendulum rods can be set and evenly arranged along the circumferential direction of the bearing.
  • the lower end surface of the soil plate 9 is an inclined surface and rises from the center to the outer wall of the protective cylinder 1.
  • the working principle of the present invention is as follows: After the hydraulic cylinder is started, the piston rod of the hydraulic cylinder drives the swing lever and the pressure rod to move down, so as to realize the external pressure of the soil in the area corresponding to the soil plate, so that the soil moves from the inside of the protective cylinder to the outside ; When the area corresponding to the area of the compaction plate is pressed, the piston rod of the hydraulic cylinder moves up. At this time, because the guide block moves along the guide groove, it moves to the area adjacent to the previous area and continues to press. The external pressure of the inner soil, when the earth in the protective cylinder is empty, causes the protective cylinder to move down a corresponding distance, and continues to the next depth of compression.

Abstract

La présente invention concerne un dispositif de formation de trou qui comprend un boîtier de protection (1). Un support de vérin hydraulique (2) est monté sur un orifice supérieur du boîtier de protection. Un vérin hydraulique (3) est monté sur le support de vérin hydraulique. Une tige de piston (4) du vérin hydraulique est dirigée vers un orifice inférieur du boîtier de protection. Un palier (5) est monté sur une partie d'extrémité de la tige de piston. Au moins une tige pivotante (6) est reliée par charnière à une bague extérieure du palier, et une autre extrémité de la tige pivotante est reliée par charnière à un côté d'un bloc de guidage (7). Une tige de pression (8) est montée au fond du bloc de guidage. La tige de pression est disposée verticalement et une plaque de pression de sol (9) est montée au niveau d'une extrémité inférieure de cette dernière. La plaque de pressage de sol est perpendiculaire à la tige de pression. Une fente de guidage est disposée sur une paroi interne du boîtier de protection. La fente de guidage est conçue pour être en forme d'onde, et le bloc de guidage est guidé de façon à coulisser sur la paroi interne du boîtier de protection, de façon à entraîner la plaque de pression de sol à se déplacer dans un manchon de protection et le long d'une direction circonférentielle du manchon de protection, ce qui permet de presser le sol pour former un trou. Le dispositif de formation de trou adopte un procédé de pressage de puits sec, ne génère pas de boue pendant un processus de pressage de trou, élimine le besoin de transport, et réduit les coûts en exigeant moins d'équipement.
