[0028] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0029] The following is combined with Figure 1-5 This application is described in further detail.

[0030] The embodiment of the present application discloses a milling wheel type rectangular pile hole forming device.

[0031] Reference Figure 1 and Figure 2 The milling wheel type rectangular pile hole forming equipment comprises a connecting frame 1 and a power cutting drum; the connecting frame 1 is provided with an interface 11 for connecting with a rotary drilling rod, and partitions 12 are symmetrically arranged on both sides of the connecting frame 1, and a connecting flange is arranged on the partition 12; the power cutting drum comprises a cutting drum 2 and a power box 3 arranged in the cutting drum 2, and a flange is arranged on the power box 3 to match the connecting flange of the partition 12, and an inspection hole 26 is reserved on the end of the cutting drum 2, and a cover plate is arranged at the inspection hole 26.

[0032] In this solution, the connecting frame 1 of the equipment is designed with an interface 11 for connecting to the rotary drilling rod, which allows the rotary drilling rod to be directly inserted and fixed by a pin shaft, ensuring the stable connection between the hole-forming equipment and the rotary drilling rig. The partitions 12 on both sides of the connecting frame 1 not only provide additional stability for the connecting frame 1, but also the connecting flanges provided thereon are used to fix and dock the hydraulic pipelines of the rotary drilling rig, thereby integrating the hydraulic system and realizing the transmission of hydraulic power. The power cutting drum includes a built-in power box 3 and a cutting drum 2. The power box 3 is fixed to the connecting frame 1 by a flange, providing the necessary power output to the cutting drum 2. The cutting drum 2 is responsible for the actual soil cutting and hole-forming work. The power transmission and motion control of the cutting drum 2 are realized by the mechanical and hydraulic systems inside the power box 3. The convenience of maintenance is particularly taken into account in the design of the equipment. The inspection hole 26 reserved at the end of the cutting drum 2 is provided with a cover plate, which is convenient for the staff to open the cover plate and directly conduct internal inspection and maintenance without disassembling the entire equipment. This is particularly important in on-site operations, as the components in the power box 3 can be quickly inspected and necessary maintenance can be performed, such as replacing worn components or checking the status of the hydraulic oil.

[0033] Reference Figure 1 , the outer edges of both ends of the cutting drum 2 are arranged with inclined picks 21 facing outwards. The design of the inclined picks 21 facing outwards at both ends of the cutting drum 2 is mainly used to enhance cutting efficiency and improve hole quality, especially when dealing with hard ground or irregular surfaces. This design of picks can more effectively cut into soil or other materials, providing more accurate rectangular pile hole operation.

[0034] The end of the cutting drum 2 is provided with a special-shaped annular rib 22 and a longitudinal rib 23. The special-shaped annular rib 22 is arranged coaxially with the cutting drum 2, and the longitudinal rib 23 is arranged along the radial direction of the cutting drum 2 and connected to the special-shaped annular rib 22. The combination of the special-shaped annular rib 22 and the longitudinal rib 23 provides additional support, allowing the cutting drum 2 to withstand greater cutting forces and mechanical stresses. This design helps the drum resist the twisting and bending forces that may be encountered during operation. By using the longitudinal rib 23 and the annular rib, the durability of the drum is significantly improved because the rib material can effectively disperse the load pressure and reduce damage caused by concentrated loads. This is especially important for long-term continuous operation. The structural reinforcement not only protects the drum, but also ensures the consistency of the cutting performance. The drum remains rigid during operation and can cut soil or rock more accurately.

[0035] The slag discharge holes 24 are provided on the special-shaped annular ribs 22, so that the slag and muddy water retained between the annular ribs and the longitudinal ribs 23 can be discharged smoothly. The slag discharge holes 24 are provided on the special-shaped annular ribs 22 to improve the working efficiency and maintenance convenience of the cutting drum 2. The main function of this design is to ensure that the slag and muddy water generated during the hole forming process can be effectively discharged to avoid accumulation and blockage.

[0036] The connection position between the special-shaped annular ribs 22 and the longitudinal ribs 23 protrudes inwardly of the ring to form a reinforcement plate, and end face picks 25 are arranged on the reinforcement plate in a spiral manner.

[0037] The raised reinforcement plate provides additional strength at the junction of the profiled annular ribs 22 and the longitudinal ribs 23, allowing the cutting drum 2 to withstand greater cutting forces and mechanical stresses. This reinforcement method helps prevent structural deformation under heavy load working conditions. The end picks 25 on the reinforcement plate are arranged in a spiral pattern. This layout can improve cutting efficiency because the spiral layout helps to cut the soil continuously and evenly, reduce vibration and increase cutting speed. The spiral arrangement of the picks also helps to discharge the material smoothly, especially when processing clay or wet soil, effectively preventing the accumulation of material inside the drum.

[0038] Reference Figure 3 A hydraulic oil channel is provided in the partition 12, one end of the hydraulic oil channel is connected to the hydraulic pipe of the power box 3, and the other end is connected to the hydraulic pipe of the rotary drilling rig to realize the communication of the hydraulic system.

[0039] By connecting the power box 3 of the hole-forming equipment to the hydraulic system of the rotary drilling rig through the hydraulic oil channel in the partition 12, efficient coordination of the two systems can be achieved. This connection ensures that the power transmission from the rotary drilling rig to the hole-forming equipment is continuous and stable, thereby improving work efficiency and equipment response speed. Providing a hydraulic oil channel in the partition 12 can effectively protect the hydraulic pipeline and avoid damage to the pipeline due to equipment vibration or external collision during operation. This built-in design reduces the risk of pipeline exposure and extends the service life of the hydraulic pipeline.

[0040] In a specific embodiment, the hydraulic oil channel can be designed as a metal pipe built into the partition 12, and its material needs to be selected from high pressure resistant and corrosion resistant materials, such as stainless steel or special alloys. The diameter and wall thickness of the pipeline should be selected according to the expected pressure and flow requirements. At both ends of the hydraulic oil channel, that is, the hydraulic pipe ends connecting the power box 3 and the rotary drilling rig, high-quality seals and fixings, such as flanges, bolts and sealing rings, should be used. These connection points need to be designed to be easy to access and maintain, while ensuring good sealing performance during long-term operation. The pipeline should be arranged according to the principles of fluid mechanics, minimizing sharp bends and excessively long straight sections to reduce pressure loss and improve system efficiency.

[0041] The connecting frame 1 is provided with a plurality of pipeline stoppers 13 arranged along the hydraulic pipes of the power box 3, and a positioning hole for the hydraulic pipe to pass through is formed between the pipeline stopper 13 and the connecting frame 1. The pipeline stopper 13 serves as a fixing point for the hydraulic pipeline to prevent the pipeline from moving or bending due to vibration or external force during the operation of the machine, thereby reducing wear and potential damage risks. This fixing method provides additional physical protection and extends the service life of the pipeline; through a stable and fixed pipeline layout, it can effectively reduce the impact of hydraulic shock and pressure fluctuations, maintain the pressure stability of the system, and improve mechanical efficiency and response speed; the setting of the positioning hole makes the installation, inspection and maintenance of the hydraulic pipeline easier. Maintenance personnel can quickly identify and access specific pipeline sections for replacement or repair, reducing downtime. In a specific embodiment, the stopper 13 is a C-shaped round rod.

[0042] Reference Figure 1 and Figure 4 The milling wheel type rectangular pile hole forming equipment also includes a support frame 4 detachably connected to the connecting frame 1, and the support frame 4 includes a support rod 41 and a leg 42 respectively hinged to the connecting frame 1, and a triangular structure is formed between the support rod 41, the leg 42 and the connecting frame 1 to provide support during transportation or placement. The support frame 4 forms a triangular structure through the support rod 41 and the leg 42 hinged to the connecting frame 1, and this structure is considered to be very stable in physics. When the equipment is transported or temporarily stored, this structure can effectively prevent the equipment from tipping over and shifting, and reduce possible damage during transportation.

[0043] The legs 42 are arc-shaped, and the arc of the legs 42 matches the shape of the power cutting drum. When working, the two legs 42 are connected by a pin shaft and blocked in the gap between the two power cutting drums. The legs 42 of this design can effectively block the gap between the power cutting drums, prevent large stones and other impurities from entering, thereby reducing damage to internal parts and improving the reliability of the equipment. When changing the state of the support frame 4, the staff first removes the support rod and the support leg from the cutting drum 2, and then installs and fixes the legs 42 at the required angle.

[0044] Reference Figure 5 The power box 3 is provided with a refueling port 31 for injecting lubricating oil and an oil drain port 32 for discharging oil. The refueling port 31 for injecting lubricating oil and the oil drain port 32 for discharging oil provided on the power box 3 are key maintenance functions that ensure the long-term health and efficiency of the hydraulic system and mechanical components of the equipment.

[0045] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
