Description

Technical Field

[0001] This utility model relates to the field of rectangular pile excavation technology, and in particular to an automated rectangular pile excavation device. Background Technology

[0002] Automated rectangular pile excavation equipment is a specialized machine used in building construction, primarily for excavating rectangular pile holes in foundation construction. It is typically used in conjunction with excavators, which provide initial positioning and support to ensure the equipment stays on target during excavation. Compared to traditional circular pile hole excavation equipment, automated rectangular pile excavation equipment can excavate rectangular pile holes more efficiently and accurately. Its automated control system significantly reduces manual intervention, improving work efficiency and construction safety. In existing technologies, the sharp (right-angled) corners of rectangular pile holes lack the natural transition curves of circular holes, failing to effectively distribute pressure from the surrounding soil layers. This can easily lead to excessive shearing or localized damage of the soil during excavation, resulting in localized collapse or hole wall collapse. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art where sharp (right-angled) corners are excessively sheared or locally damaged during the excavation of rectangular pile holes, leading to local collapse or hole wall collapse. This invention proposes an automated rectangular pile excavation device.

[0004] The technical solution of this utility model is as follows: an automated rectangular pile excavation device, including a drilling machine and multiple corner ends set on the drilling machine, and further including: a support frame fixedly connected to the drilling machine corresponding to the corner ends, each of the support frames being provided with a support mechanism that fits tightly against the corresponding corner end when opened; and a limiting mechanism set on the support frame to allow the support mechanism to move vertically.

[0005] Optionally, the support mechanism includes a support base fixedly connected to the top of the support frame, and cylinders are fixedly connected to the upper surface of the support frame. The piston rod of the cylinder moves through the support base and is fixedly connected to a sliding top seat. A support plate that is inserted into a rectangular hole and closely abuts the corner is fixedly connected to the lower surface of the sliding top seat.

[0006] Optionally, each of the support plates has a soil-inserting tip at the end away from the sliding top seat.

[0007] Optionally, the limiting mechanism includes multiple support base sleeves fixedly connected to the upper surface of the drilling machine and corresponding to the corner ends. Each support base sleeve and the drilling machine is provided with a limiting through hole to lock the support plate. The top of the sliding top seat is also provided with a support sliding hole that slides with the support frame.

[0008] Optionally, each support frame is fixedly connected to a base at its bottom end, and the upper surface of the base is provided with a first bolt.

[0009] Optionally, a fixing seat is fixedly connected to the bottom outer wall of the support base.

[0010] Optionally, each of the mounting bases is provided with a pair of second bolts.

[0011] Optionally, the bottom of the drilling machine is fixedly connected with multiple conical digging heads.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention utilizes the coordination of a support frame, support mechanism, corner ends, and limiting mechanism to provide support for the sharp ends of the rectangular borehole. The support frame effectively stabilizes the borehole wall, preventing localized soil collapse at the borehole opening due to uneven soil pressure or external forces, especially at the sharp corners of the rectangular borehole where soil pressure is concentrated. Furthermore, after the drilling rig is removed from the borehole, the support frame is slowly removed immediately afterward, allowing the soil structure to gradually recover and preventing sudden loss of support that could lead to soil collapse.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] like Figure 1 - Figure 5 As shown, this utility model proposes an automated rectangular pile excavation device, including a drilling machine 1 and several corner ends 12 disposed on the drilling machine 1. Several conical excavating heads 11 are fixedly connected to the bottom of the drilling machine 1. These conical excavating heads 11 are also triangularly arranged. This design increases the sharpness and precision of the cutting, allowing the drilling machine to cut soil or rock more smoothly, reducing resistance during operation, and thus improving work efficiency. Simultaneously, the triangular tips help reduce the contact area with the soil, thereby reducing friction. This helps reduce the mechanical load, energy consumption, and improve the excavator's durability. Furthermore, the triangular shape helps concentrate pressure in the tip area, increasing penetration power, allowing the device to more easily break through soil layers or hard strata, especially in complex soils such as clay or rock. Finally, the arrangement of multiple triangular tips makes the device more stable during excavation, reducing offset and vibration, thus ensuring the accuracy of the hole and the precision of the excavation operation. Furthermore, it also helps to distribute the load on the bottom of the excavator, reducing wear on a single tip, thereby extending the service life of the equipment. It also includes: a support frame 2 fixedly connected to the drilling machine 1 and corresponding to the corner end 12. Each support frame 2 has a base 23 fixedly connected to its bottom end. The upper surface of the base 23 is provided with a first bolt 24. The first bolt 24 can tightly connect two or more components together, preventing them from loosening or separating during operation. Simultaneously, the first bolt 24 can effectively transmit force and load from one component to another. Especially under conditions of high pressure, torque, or vibration, the first bolt 24 plays an important load-bearing role, ensuring the mechanical balance between components. Furthermore, the friction generated by tightening the first bolt 24 can prevent the connection from loosening due to vibration or external forces during use. Finally, unlike welding or bonding, bolted connections allow for adjustment or disassembly as needed. This makes maintenance, replacement of components, or equipment adjustment easier without damaging the overall structure.

[0022] Among them, such as Figure 2 and Figure 4As shown, each support frame 2 is equipped with a support mechanism that, when opened, fits tightly against the corresponding corner end 12. This support mechanism provides support for the sharp ends of the rectangular hole, while the support frame 2 effectively stabilizes the hole wall, preventing local collapse of the soil layer in the hole opening area due to uneven soil pressure or external forces, especially at the sharp corners of the rectangular hole, where soil pressure is easily concentrated. The support mechanism includes a support base 21 fixedly connected to the top of the support frame 2. A cylinder 22 is fixedly connected to the upper surface of each support frame 2. The cylinder 22 is relatively long, which means a larger piston stroke and a longer range of motion, better adapting to equipment requiring longer movements. The piston rod of the cylinder 22 moves through the support base 21 and is fixedly connected to a sliding top seat 42. The sliding top seat 42 locks the top of the support base 3, forming a physical locking state. This design ensures that the component remains fixed in a specific position, preventing further sliding or movement and ensuring the normal operation of the equipment within a specific area. A support plate 4 is fixedly connected to the lower surface of the sliding top seat 42, inserting into a rectangular hole and closely abutting the corner end 12. The support plate 4 is designed to fit tightly against the corner end 12, ensuring that the corner end 12 and the support plate 4 are not jammed, and reducing the resistance when the support plate 4 moves downward. Each end of the support plate 4 away from the sliding top seat 42 is equipped with a soil-inserting tip 41. The soil-inserting tip 41 makes the bottom of the support plate 4 sharp and easy to insert into the soil. Its material needs to have sufficient hardness and wear resistance to ensure it remains sharp even after long-term use. Common materials include high-strength steel and alloys, which can effectively prevent the tip from wearing down rapidly due to friction and pressure. For more compact or heavy soil, the design of the soil-inserting tip 41 can first break up soil particles, creating a looser environment more suitable for insertion, thus reducing resistance and making the insertion process smoother.

[0023] Furthermore, such as Figure 2 - Figure 5As shown, the limiting mechanism ensures the vertical movement of the support mechanism, thus precisely controlling the position of the support plate 4. This allows the support plate 4 to perform its task at a specific position during construction, avoiding the effects of misoperation or inaccuracy. Simultaneously, the limiting mechanism supporting the vertical movement of the support plate 4 is typically equipped with a stability control system, which automatically adjusts the equipment's balance during movement to prevent tilting or damage caused by imbalance. The limiting mechanism, installed on the support frame 2 to enable vertical movement of the support mechanism, includes multiple support base sleeves 3 fixedly connected to the upper surface of the drilling machine 1, corresponding to the corner ends 12. The main function of the support base sleeves 3 is to fix the bottom of the support frame 2, thereby improving the stability of the support frame 2. A fixing seat 31 is fixedly connected to the bottom outer wall of the support base sleeve 3. The main function of the fixing seat 31 is to support the bolts, ensuring they remain in the correct position during installation and preventing bolt misalignment or instability. This is crucial for ensuring the tightness of the bolts and the reliability of the structural connection. Simultaneously, the fixing seat 31 also helps ensure the accurate positioning of the bolts within the structure. It provides a predetermined position to ensure the alignment of the bolt with the structural connection point, thereby avoiding structural deformation or uneven stress caused by improper bolt installation. Furthermore, the use of the fixing seat 31 greatly improves the efficiency of bolt installation. The fixing seat 31 eliminates the need for repeated manual adjustments during bolt installation, reducing installation time and operational difficulty, and improving work efficiency. Finally, the fixing seat 31 is usually designed to conform to the size and shape of the bolt, ensuring that the bolt can be firmly fixed in the predetermined position and is not prone to falling off or shaking during installation. Especially under high loads or complex working conditions, the design of the fixing seat 31 is particularly important for ensuring the long-term stability of the bolt after installation. Each fixing seat 31 is equipped with a pair of second bolts 32, which can tightly connect two or more components together, preventing them from loosening or separating during operation. At the same time, the friction generated by tightening the second bolts 32 can prevent the connection from loosening due to vibration or external forces during use. Finally, unlike welding or bonding, bolted connections allow for adjustment or disassembly as needed. This makes maintenance, replacement of parts, or adjustment of equipment easier and does not require damage to the overall structure. Both the support base sleeve 3 and the drilling machine 1 are provided with limiting holes 33 to hold the support plate 4 in place. These limiting holes 33 ensure the support plate 4 remains in the correct vertical position, guaranteeing more precise movement. By preventing the support plate 4 from tilting or sliding, the support base sleeve 3 allows for smoother equipment operation, thereby improving work efficiency. The support plate 4 can operate without obstructions and in a stable manner, reducing unnecessary adjustments or downtime. The top of the sliding top seat 42 is also provided with a support sliding hole 43 that slides with the support frame 2. The support sliding hole 43 serves the same function as the limiting holes 33.

[0024] In this embodiment, when using automated rectangular pile excavation equipment, such as Figure 1 As shown, the drilling machine 1 digs vertically into the soil surface, so that only the top of the drilling machine 1 is exposed above the soil. Simultaneously, as the drilling machine 1 moves vertically into the soil, the support plate 4 moves into the soil along its corresponding lower corner 12 until the lower surface of the sliding top seat 42 abuts against the top of the support base 3. At this point, the drilling machine 1 can be slowly started, allowing it to move slowly vertically upwards. Before moving the drilling machine 1, all cylinders 22 need to be opened. The piston rod of cylinder 22 will eventually drive the support plate 4 to remain pressed against the sharp end of the rectangular hole dug by the drilling machine 1, thus ensuring that the sharp end of the rectangular hole does not collapse. Finally, after the drilling machine 1 has completely moved out of the rectangular hole, all cylinders 22 need to be opened again, allowing the support plate 4 to slowly move out of the rectangular hole. Furthermore, the vertical movement speed of the support plate 4 into the soil is greater than the vertical movement speed of the excavator 1 upwards. This ensures that as the excavator 1 moves upwards, the support plate 4 will continuously support the sharp end of the rectangular hole, thus preventing the sharp end from collapsing due to the excavator 1 dislodging from the rectangular hole. Finally, multiple support plates 4 can be moved on the excavator 1 to the following position: Figure 1 The state shown.
