Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and particularly to a drilling and punching equipment for building construction piling. Background Art

[0002] In the field of building construction, especially in foundation engineering, piling is a key step in constructing a stable foundation structure. Traditional drilling and punching equipment drills into soil or rock by rotating a drill rod to create holes for placing pile foundations. However, under some geological conditions, such as soft soil layers, sandy soil layers or in the presence of groundwater, after the hole is drilled, the hole wall may become unstable, increasing the risk of hole collapse. Once collapse occurs, not only does it require re-drilling, increasing construction costs and time, but it may also pose a threat to the safety of the construction site.

[0003] To avoid hole collapse, traditional methods usually adopt the way of pre-installing a casing (conduit), that is, pressing a casing made of steel or other materials into the ground during the drilling process to keep the hole wall stable. However, this method also has its limitations: for example, the use of the casing increases additional costs and workload, and in some cases, due to complex geological conditions, the casing is difficult to insert smoothly, or it may cause disturbance to the surrounding soil when pulled out, instead affecting the hole wall stability.

[0004] Therefore, a drilling and punching equipment for building construction piling is needed to solve the above problems. Summary of the Invention

A driving tooth groove 6 is formed on the support sliding frame 2. A plurality of extrusion plates 7 are slidably installed on the screw conveyor rod 4. A cam 8 is rotatably installed inside the screw conveyor rod 4. The extrusion plate 7 is drivingly connected to the cam 8. The cam 8 is drivingly connected to the driving tooth groove 6 through a one-way mechanism; by installing the drilling device on the carrier vehicle 1, it is convenient to move the drilling device. By slidably arranging the extrusion plate 7 on the screw conveyor rod 4 and arranging a cam 8 that can drive the extrusion plate 7 inside the screw conveyor rod 4, when the cam 8 rotates, it can drive the extrusion plate 7 to perform reciprocating telescopic motion, thereby tamping the surface of the drilled hole to prevent the hole from collapsing. By making the cam 8 drivingly connected to the driving tooth groove 6 through a one-way mechanism, when the installation sliding seat 3 slides upward and resets, the one-way mechanism can automatically drive the cam 8 to rotate under the drive of the driving tooth groove 6, without a separate driving device, saving energy.

The spiral conveyor rod 4 outputs the soil drilled out by the drilling head 5 from the hole. The setting of the support plate 27 can ensure the stability of the spiral conveyor rod 4 and the drilling head 5.
