Abstract

A hole forming device comprises a protective housing (1). A hydraulic cylinder support (2) is mounted on an upper port of the protective housing. A hydraulic cylinder (3) is mounted on the hydraulic cylinder support. A piston rod (4) of the hydraulic cylinder is directed to a lower port of the protective housing. A bearing (5) is mounted on an end portion of the piston rod. At least one pivoting rod (6) is hinge-connected to an outer ring of the bearing, and another end of the pivoting rod is hinge-connected to one side of a guide block (7). A pressing rod (8) is mounted at the bottom of the guide block. The pressing rod is vertically arranged and a soil pressing plate (9) is mounted at a bottom end thereof. The soil pressing plate is perpendicular to the pressing rod. A guide slot is provided on an inner wall of the protective housing. The guide slot is configured to be wave-shaped, and the guide block is guided thereby to slide on the inner wall of the protective housing, so as to drive the soil pressing plate to move in a protective sleeve and along a circumferential direction of the protective sleeve, thereby pressing soil to form a hole. The hole forming device adopts a dry hole pressing method, does not generate slurry during a hole pressing process, eliminates the need for transportation, and reduces costs by requiring less equipment.

Description

Hole forming device

Technical field

The invention relates to a hole forming device, which is used for hole formation in the construction process in the construction field.

Background technique

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.

Summary of the Invention

To overcome the shortcomings of the prior art, 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.

There are a plurality of swing levers, which are evenly arranged along the circumferential direction of the bearing.

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.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic diagram of the main structure of the present invention.

Detailed ways

The present invention is further described below with reference to specific embodiments. The advantages and features of the present invention will become clearer with the description. However, these embodiments are only exemplary and do not limit the scope of the present invention in any way. Those skilled in the art should understand that the details and forms of the technical solutions of the present invention can be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements fall within the protection scope of the present invention.

Referring to FIG. 1, 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.

In order to improve the pressing efficiency, 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.
