Description

Technical Field

[0001] This invention relates to the field of road light pole construction technology, specifically to a road light pole construction excavation device and its usage method. Background Technology

[0002] The street light pole excavation device is a specialized engineering tool used for earthwork excavation during the foundation construction of light poles in urban roads, municipal green belts, and other areas. It primarily uses a mechanical structure to drill and excavate holes in the soil at the light pole installation site, creating a foundation pit or hole that meets the required dimensions for the light pole foundation. This provides the necessary foundation conditions for subsequent processes such as fixing the light pole and pouring concrete.

[0003] However, the efficiency of existing road light pole construction excavation equipment needs to be improved. When in use, the traditional road light pole construction pit is square, and it is mainly excavated by a combination of manual and mechanical methods. The average excavation time is relatively long, resulting in a long time occupied on the foundation working surface, which affects subsequent work and leads to low foundation construction efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a road light pole construction excavation device and its usage method to solve the problems of low efficiency, large excavation area of ​​traditional square foundation pits, and long time occupied by foundation working surfaces in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A road light pole construction excavation device includes a fixed plate, a connecting column fixedly connected to the bottom of the fixed plate, a drill bit fixedly connected to the bottom end of the connecting column, and a spiral propulsion blade fixedly connected to the outer surface of the connecting column located between the fixed plate and the drill bit.

[0006] Preferably, a hydraulic device output shaft is fixedly connected to the center of the top of the fixed plate, a protective cover is fixedly connected to the edge of the top of the fixed plate, a robotic arm is fixedly connected to the top of the protective cover, and the end of the robotic arm away from the protective cover is fixedly connected to the control vehicle body.

[0007] Preferably, the connecting column has a receiving groove inside near its bottom end, and a sensing probe is fixedly connected inside the receiving groove.

[0008] Preferably, the helical propulsion blade should be cylindrical from top to bottom, except for the bottom drill tip.

[0009] Preferably, the spiral propulsion blade is columnar from the side closest to the connecting post to the side furthest from the connecting post.

[0010] Preferably, the drill bit has a triangular cross-section.

[0011] The method of using this road light pole excavation device includes the following steps: S1: Construction Preparation and Positioning. The driver moves the control vehicle to the construction site, ensuring it is parked in a stable and suitable position. Then, the driver operates the robotic arm within the control vehicle to adjust the positions of the fixed plate, connecting column, drill bit, and auger propulsion blades, precisely aligning them with the designated light pole construction points, thus preparing for subsequent excavation.

[0012] S2: Start the rotating mechanism. After confirming that the device is accurately positioned, start the hydraulic device at the center of the top of the fixed plate. When the hydraulic device is working, its output shaft drives the fixed plate to rotate, which in turn drives the spiral propulsion blades and drill bit to rotate around the connecting column, so that the blades and drill bit obtain rotational power and prepare for drilling into the ground.

[0013] S3: Depression and excavation to form the foundation pit. While the auger blades and drill bit continue to rotate, the operator controls the robotic arm to gradually lower the entire device (including the fixed plate, connecting column, drill bit, and auger blades). Under the combined action of rotation and depression, the drill bit first contacts the ground and rotates to drill in, then the auger blades continue to rotate, cutting and advancing the soil, gradually forming a cylindrical foundation pit that meets the size requirements of the light pole foundation below the ground.

[0014] S4: Underground Pipeline Detection and Risk Avoidance. Throughout the excavation process, the sensor probe inside the receiving slot of the connecting column descends along with the connecting column, continuously detecting the area beneath the excavating ground. If the sensor probe detects underground obstacles such as pipes or cables, it will immediately transmit the detected information to the control vehicle via digital electrical signals. Upon receiving the information, the driver should immediately stop the device's descent to avoid further excavation and damage to underground pipelines. After the obstacle issue has been identified and resolved, a decision can be made on whether to continue construction based on the actual situation.

[0015] S5: Stop Excavation and Soil Removal. When the foundation pit is excavated to the set depth (meeting the depth requirements for light pole foundation construction), the operator first stops the rotation of the auger blades and drill bit, and then stops the device's descent. Subsequently, by operating the robotic arm, the auger blades and the soil carried between them are driven upwards, bringing the soil inside the cylindrical foundation pit to the ground, completing the soil removal work and providing a clean and standardized construction foundation for subsequent light pole fixing, concrete pouring, and other processes.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This road light pole construction excavation device, through the arrangement of spiral propulsion blades and drill bits, can form a cylindrical foundation pit during use, significantly reducing the excavation area compared to traditional square pits. This design not only saves time in securing the foundation work surface and reduces the impact on the surrounding environment, especially in areas such as green belts where it minimizes damage to vegetation, but also improves construction efficiency. This allows for faster integration of subsequent processes such as bottom cleaning, rebar cage binding, embedded part positioning and welding, grounding system installation, and concrete pouring, avoiding the impact of prolonged excavation time on severe weather such as rainy seasons and reducing the occurrence of problems like flooding of the foundation pit. Furthermore, the smaller excavation area results in smaller excavated soil blocks, facilitating timely cleanup and preventing soil pollution of the surrounding environment.

[0017] 2. The spiral propulsion cutting tool should be cylindrical from top to bottom, except for the bottom drill tip; the connection between the drill tip and the cutting tool should be a spiral transition.

[0018] 3. The drill bit has a triangular cross-section with a pointed bottom and a wide top, which minimizes the initial contact area with the ground. This allows the drill bit to rotate and drill into the ground more smoothly after contacting the ground, laying the foundation for the subsequent entry of the spiral propulsion blades into the ground and further improving the convenience and efficiency of excavation.

[0019] 4. The hydraulic system on top of the fixed plate provides stable power for the rotation of the entire device, ensuring continuous and stable rotation of the helical propulsion blades and drill bit. A cylindrical protective cover surrounds the hydraulic system, effectively protecting it from external dust, dirt, and other contaminants, extending its service life. The robotic arm enables flexible control of the fixed plate and its bottom components, including forward, backward, left, and right translation and lifting, facilitating precise positioning of the construction site and meeting the needs of different construction scenarios. The control vehicle provides a comfortable operating environment for the driver, allowing the driver to complete the entire excavation process from inside the vehicle, improving the convenience and safety of the construction.

[0020] 5. The sensing probe located near the bottom of the connecting column functions similarly to a ground-penetrating radar probe. During the excavation process, it can continuously detect the ground, including various pipelines such as power cables, metal or plastic water supply pipes, natural gas pipelines, communication cables, and fiber optic cables. When these pipelines are detected, the sensing probe transmits the information to the control vehicle via digital electrical signals, providing timely feedback to the operator. This allows the operator to stop excavating, effectively mitigating the risk of damaging underground pipelines during excavation and improving construction safety. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-4 As shown, the present invention provides a technical solution: A road light pole excavation device includes a fixed plate 1, a connecting column 2 fixedly connected to the bottom of the fixed plate 1, a drill bit 3 fixedly connected to the bottom end of the connecting column 2, and a spiral propulsion blade 4 fixedly connected to the outer surface of the connecting column 2 between the fixed plate 1 and the drill bit 3. In use, the fixed plate 1 is driven to rotate, causing the spiral propulsion blade 4 and the drill bit 3 to rotate around the connecting column 2 as a center. The spiral propulsion blade 4 is controlled to gradually sink and rotate, drilling into the ground to gradually form a cylindrical pit. The spiral propulsion blade 4 stops sinking and rotating at a set pit depth, driving the spiral blade and the soil between the blades to rise. The soil inside the cylindrical foundation pit is excavated, making it easier for workers to clean the bottom later. By changing the traditional square foundation pit to a circle, the excavation area is reduced, saving time on foundation work surfaces and improving efficiency. Specifically, the spiral propulsion blade 4 rotates and presses down to excavate the cylindrical foundation pit. The excavation area is smaller than that of the traditional square foundation pit, which improves construction efficiency. In addition, the foundation pit excavation time is shortened, which facilitates the rapid binding of the steel cage, the positioning and welding of embedded parts, and the installation of the grounding system. It also facilitates the rapid completion of concrete pouring and avoids flooding of the foundation pit during the rainy season. Furthermore, due to the smaller excavation area, the volume of the excavated soil is smaller, and the soil in the green belt can be cleaned up in time to avoid pollution.

[0024] In this embodiment, preferably, a hydraulic device 5 output shaft is fixedly connected to the top center of the fixed disk 1, a protective cover 6 is fixedly connected to the top edge of the fixed disk 1, a robotic arm 7 is fixedly connected to the top of the protective cover 6, and a control vehicle body 8 is fixedly connected to the end of the robotic arm 7 away from the protective cover 6. In use, the control vehicle body 8 is driven to the processing site, the hydraulic device 5 is activated to drive the fixed disk 1 to rotate, causing the spiral propulsion blade 4 and drill bit 3 to rotate around the connecting column 2. The driver inside the control vehicle body 8 controls the robotic arm 7 to gradually descend to a predetermined position. The spiral propulsion blade 4 rotates and drills into the ground, gradually forming a cylindrical pit. When the pit reaches the set depth, the spiral propulsion blade 4 stops sinking and rotating. The robotic arm 7 drives the spiral blade and the soil between the blades to rise, excavating the soil inside the cylindrical pit. The protective cover 6 is cylindrical and is fitted over the hydraulic device 5 to protect it from external environmental damage. The robotic arm 7 controls the forward, backward, left, right and vertical movement and lifting of the fixed plate 1 and its bottom components, thereby positioning them. The operator sits inside the control vehicle body 8 to operate the system. The specific details are existing technology and will not be explained in detail.

[0025] In this embodiment, preferably, the connecting column 2 has a receiving groove 9 inside near its bottom end. A sensing probe 10 is fixedly connected inside the receiving groove 9. In use, the connecting column 2 descends, causing the sensing probe 10 inside to descend as well. The sensing probe 10 continuously probes the ground being excavated. If a pipe or cable is detected, a digital electrical signal is transmitted to the control vehicle body, which then informs the operator to stop the excavation and avoid risks. Here, the sensing probe 10 has the function of a ground-penetrating radar probe. In addition to detecting metal pipelines, it can also detect some non-metallic pipelines, including but not limited to: power cables, metal or plastic water supply pipes, natural gas pipelines, communication cables, and communication optical cables, etc. The specific details are existing technology and will not be explained in detail.

[0026] In this embodiment, preferably, the spiral propulsion blade 4 is spiral-shaped from its top to its bottom. In use, the spiral propulsion blade 4 rotates and drills into the ground, gradually forming a cylindrical pit. When the pit reaches a set depth, the spiral propulsion blade 4 stops sinking and rotating. The robotic arm 7 drives the spiral blade and the soil between the blades to rise, excavating the soil inside the cylindrical pit, which is convenient for workers to clean the bottom later. The spiral propulsion blade 4 sinks while rotating, which increases the drilling efficiency.

[0027] In this embodiment, preferably, the spiral propulsion blade 4 is constricted from the side near the connecting column 2 to the side away from the connecting column 2. When in use, the spiral propulsion blade 4 rotates and drills into the ground, gradually forming a cylindrical pit. When the pit reaches the set depth, the spiral propulsion blade 4 stops sinking and rotating. The robotic arm 7 drives the spiral blade and the soil between the blades to rise, excavating the soil inside the cylindrical pit, which is convenient for workers to clean the bottom later.

[0028] In this embodiment, preferably, the drill bit 3 has a triangular cross-section. When in use, the hydraulic device 5 is activated to drive the fixed disk 1 to rotate, which in turn drives the spiral propulsion blade 4 and the drill bit 3 to rotate around the connecting column 2. The robotic arm 7 is controlled to gradually sink to the specified position. The drill bit 3 first contacts the ground and rotates to drill in. The drill bit 3 is pointed at the bottom and wide at the top, with a triangular cross-section to minimize the contact area with the ground, so that it can rotate and drill into the ground after contacting the ground, which facilitates the subsequent entry of the spiral propulsion blade 4 into the ground.

[0029] In practical applications, the road light pole excavation device of this embodiment must strictly follow the following steps to ensure construction accuracy, safety, and efficiency: S1: Site Positioning and Equipment Debugging. The driver of the control vehicle 8 moves to the construction area and determines the precise construction points according to the light pole installation design drawings. Using tools such as a level, the driver ensures the control vehicle 8 is parked stably. Then, the driver operates the robotic arm 7 inside the control vehicle 8, adjusting the spatial posture of the fixed plate 1, connecting column 2, drill bit 3, and spiral propulsion blade 4, ensuring the drill bit 3's central axis is vertically aligned with the construction point. Simultaneously, the driver checks the circuit connections and operating status of components such as the hydraulic device 5 and the sensor probe 10 to ensure the equipment is fault-free.

[0030] S2: Rotary power start. After confirming that the positioning and debugging are correct, start the hydraulic device 5. Its output shaft drives the fixed plate 1 to rotate at a stable speed (the speed can be preset according to the soil hardness, generally 30-60 rpm). Then, through the transmission of the connecting column 2, the spiral propulsion blade 4 and the drill bit 3 rotate synchronously around the central axis of the connecting column 2. At this time, the blade and the drill bit form a continuous cutting force, preparing for entering the soil.

[0031] S3: Gradual Lowering Excavation. With the helical propulsion blade 4 and drill bit 3 rotating, the operator, controlled by the robotic arm 7, slowly lowers the device at a speed of 0.5-2 cm / s. Due to its triangular cross-section design, drill bit 3 contacts the ground and quickly cuts into the soil before the blades. The helical propulsion blade 4 then lowers, utilizing its spiral columnar structure to create a dual "cutting-lifting" effect on the soil during rotation, conveying the broken soil upwards along the helical surface of the blades, gradually forming a cylindrical pit with a smooth inner wall. Throughout the process, the robotic arm 7 must maintain the device's verticality in real time to prevent the pit from tilting.

[0032] S4: Real-time Detection and Risk Management. During excavation, the sensor 10 at the bottom of the connecting column 2 descends synchronously with the device, scanning and detecting within a 3-meter underground area at a frequency of twice per second. When a metal or non-metal pipeline (such as a pipe or cable with a diameter ≥ 5cm) is detected, the sensor 10 immediately sends an audible and visual alarm signal to the display terminal of the control vehicle body 8, and displays the vertical distance of the obstacle from the drill bit (error ≤ 3cm). After receiving the signal, the driver must immediately stop the descent and pause the rotation, lift the device out of the pit using the robotic arm 7, and restart the operation only after the pipeline route has been manually checked and the construction point adjusted.

[0033] S5: Depth Achievement and Soil Removal. When the depth sensor on the robotic arm 7 indicates that the pit depth has reached the design value (e.g., 1.2 meters, 1.5 meters, 3 meters, etc.), the operator first shuts off the hydraulic device 5, stops the rotation of the spiral propulsion blade 4 and drill bit 3, and then uses the robotic arm 7 to lift the device at a constant speed of 1-3 cm / s. At this time, the soil carried between the spiral propulsion blades 4 is carried out of the ground as the device rises and falls into the preset soil dumping area. After the device is completely removed from the pit, check whether the pit depth and diameter meet the requirements (diameter error ≤ 5 mm). After confirming that there are no errors, the single excavation is completed, providing a standard working surface for subsequent light pole foundation construction (such as bottom cleaning, rebar tying, etc.).

[0034] Working principle: This device provides rotational power through a hydraulic system. By utilizing the synergistic effect of the spiral propulsion blade and the triangular drill bit, the traditional square foundation pit is optimized into a cylindrical shape, significantly reducing the excavation area. The robotic arm achieves precise positioning and lifting control, and the sensing probe avoids underground pipeline risks in real time. The entire process, through standardized operating procedures, greatly shortens the foundation construction time and improves the efficiency and safety of street light pole construction.
