Description

Technical Field

[0001] This application belongs to the field of vibratory stone crushing pile technology, specifically a vibratory stone crushing pile verticality control auxiliary device. Background Technology

[0002] Vibro-compacted stone piles are a commonly used pile type in foundation treatment technology. They primarily utilize the combined action of vibration generated by a vibro-compactor and high-pressure water flow for construction. At the start of construction, the vibro-compactor, driven by a motor or other power device, generates high-frequency vibrations. Simultaneously, a high-pressure water jet is ejected through a matching high-pressure water jet device. This high-pressure water jet creates a hole in the foundation soil. The vibro-compactor then sinks continuously into this hole using its own vibration and the force of the water jet. Once the pre-designed depth is reached, the hole is filled with crushed stone and other materials. During the filling process, the vibro-compactor continues to vibrate, causing the crushed stone to move continuously within the pile hole. This reduces the friction between the crushed stone, allowing them to better compress and rearrange themselves, thus achieving dense filling. Vibro-compacted stone piles are suitable for various geological conditions, especially in soft soil foundation treatment. They can effectively prevent excessive soil compression and heave, making them a highly efficient foundation reinforcement method.

[0003] Most existing vibratory stone crushing piles are lifted by cranes for construction. In actual operation, due to the interplay of various complex factors, vibratory stone crushing piles are prone to tilting and it is difficult to ensure ideal verticality. For example, when encountering local hard soil layers and soft soil layers, or special geological structures such as underground cavities and boulders, the resistance experienced by the pile body during vibration and sinking will be significantly different in different directions. This unbalanced resistance will continuously push the pile body to shift towards the direction with less resistance, thus gradually deviating from the vertical state.

[0004] If the verticality deviates and is not corrected in time, it will pose a serious potential threat to the quality of the entire foundation treatment project and the stability of the subsequent building structure, which may lead to uneven foundation settlement, building tilting and cracking, etc. Therefore, an auxiliary device for controlling the verticality of vibratory crushed stone piles is provided. Utility Model Content

[0005] The purpose of this application is to provide an auxiliary device for controlling the verticality of vibratory crushing stone piles in order to solve the problems mentioned above.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] refer to Figure 1 , Figure 2 and Figure 3 A vibratory stone crushing pile verticality control auxiliary device includes an auxiliary main support frame 1, and multiple inclined reinforcing rods 11 are installed in an equally spaced array inside the auxiliary main support frame 1; by setting multiple inclined reinforcing rods 11, the overall structural strength of the auxiliary main support frame 1 can be improved.

[0022] refer to Figure 1 , Figure 2 The top surface of the auxiliary main support frame 1 is provided with a circular through hole 2. The vibratory rock-breaking pile body 3 is installed inside the circular through hole 2. An auxiliary control mechanism 4 for limiting the vibration rock-breaking pile body 3 is installed inside the circular through hole 2. The vibration rock-breaking pile body 3 passes through the circular through hole 2, which facilitates the subsequent control of the verticality of the vibration rock-breaking pile body 3 by the auxiliary control mechanism 4.

[0023] refer to Figure 1 , Figure 2The auxiliary control mechanism 4 includes a push plate 401, a hydraulic telescopic cylinder 402, a spring 403, a limit clamp 404, a laser displacement sensor 405, and a control box 406. Multiple push plates 401 are installed inside the circular through hole 2. Multiple hydraulic telescopic cylinders 402 corresponding to the push plates 401 are fixedly installed on the top surface of the auxiliary main support frame 1. The telescopic ends of the hydraulic telescopic cylinders 402 are fixed to one side of the push plate 401. The hydraulic telescopic cylinders 402 are connected to an external hydraulic supply tank, thus enabling the drive of the push plates 401. The hydraulic supply tank stores hydraulic oil. When the push plates 401 need to move back and forth, the hydraulic system controls the valves... The hydraulic oil supply path is opened, allowing hydraulic oil to be pumped into the piston chamber of the hydraulic telescopic cylinder 402. The pressure of the hydraulic oil pushes the piston and the connected push plate 401 forward, achieving the extension action of the push plate. When it is necessary to retract the push plate 401, the control valve switches the flow direction of the hydraulic oil, allowing the hydraulic oil to enter the other chamber of the hydraulic telescopic cylinder 402, pushing the piston and push plate 401 backward. At the same time, the hydraulic oil that was originally on the other side is discharged back to the hydraulic supply tank or flows back to the tank through the return oil line. In this way, the circulation and pressure change of the hydraulic oil realizes the forward and backward movement of the push plate 401. The model of the hydraulic telescopic cylinder 402 can be HOB 125 / 63×500. Its piston diameter is 125mm, rod diameter is 63mm, and extension length is 500mm. It can provide sufficient thrust and pull force to drive the push plate 401 for precise displacement control. There are various models of hydraulic telescopic cylinder 402, and specific ones can be selected according to actual needs.

[0024] refer to Figure 1 , Figure 2 and Figure 4 Multiple springs 403 are evenly spaced on the side of the push plate 401 away from the hydraulic telescopic cylinder 402. Each of the springs 403 is fixedly mounted with a limiting clamp 404 on the end away from the push plate 401. Multiple grooves 12 are provided on one side of the limiting clamp 404. An auxiliary moving roller 13 is rotatably connected inside each groove 12. A rubber pad 15 is fixedly installed on the outer surface of the auxiliary moving roller 13. The push plate 401 moves forward under the drive of the hydraulic telescopic cylinder 402, which facilitates the movement of the springs 403 and the push plate 401 towards the vibratory crushed stone pile body 3 to clamp it and maintain its verticality. The auxiliary moving roller 13 allows the vibratory crushed stone pile body 3 to move up and down better. The rubber pad 15 reduces the impact of the auxiliary moving roller 13 on the surface of the vibratory crushed stone pile body 3.

[0025] refer to Figure 1 , Figure 2 and Figure 4A laser displacement sensor 405 is fixedly installed on the top surface of the push plate 401, and a control box 406 is fixedly installed on the top surface of the auxiliary main support frame 1. The laser displacement sensor 405 and the hydraulic telescopic cylinder 402 are both electrically connected to the control box 406. The monitoring end of the laser displacement sensor 405 is aligned with the vibratory crushed stone pile body 3. The verticality of the pile body is dynamically monitored by real-time monitoring of the distance between the laser displacement sensor 405 and the vibratory crushed stone pile body 3. The laser displacement sensor 405 adopts the Micro-Epsilon optoNCDT1420 series laser displacement sensor, which has the characteristics of high precision and fast response. It can effectively detect any tilt of the vibratory crushed stone pile body 3. When the vibratory crushed stone pile body 3 is detected to be offset, the sensor will immediately feed back the signal to the control element in the control box 406, such as a PLC controller or a microcontroller. After receiving the offset signal, the control element will start the hydraulic telescopic cylinder 402 at the offset position. According to the direction and degree of offset, the push plate 401 will be pushed to move and straighten the vibratory crushed stone pile body 3, so as to restore it to a vertical state, thereby ensuring the construction quality.

[0026] refer to Figure 1 , Figure 2 An L-shaped support plate 5 is fixedly installed on the bottom surface of the auxiliary main support frame 1. A circular fixing hole 14 is opened on the top surface of the L-shaped support plate 5 near the corner. The L-shaped support plate 5 facilitates the support of the auxiliary main support frame 1. The circular fixing hole 14 allows personnel to use anchor nails to pass through the inside of the circular fixing hole 14 and drive them into the ground, thus improving the stability of the auxiliary main support frame 1.

[0027] refer to Figure 1 , Figure 2 and Figure 3 A housing 6 is fixedly installed on the top surface of the L-shaped support plate 5. A rectangular through hole 7 is opened inside the housing 6 on the top surface of the auxiliary main support frame 1. A fixing plate 8 is installed inside the housing 6. Two universal wheels 9 are rotatably connected to the bottom surface of the fixing plate 8. An electric push rod 10 is fixedly installed on the top surface of the housing 6. The telescopic end of the electric push rod 10 extends into the interior of the housing 6 and is fixed to the top surface of the fixing plate 8. When the auxiliary main support frame 1 is not moving, the universal wheels 9 will be stored inside the housing 6 under the action of the electric push rod 10. When the auxiliary main support frame 1 needs to be moved, the electric push rod 10 will drive the universal wheels 9 to move downwards, and the universal wheels 9 will assist the main support frame 1 in being lifted up under the continuous movement of the electric push rod 10. This makes it easier for the universal wheels 9 to drive the auxiliary main support frame 1 to move, improving convenience.

[0028] The implementation principle of the verticality control auxiliary device for vibratory crushing stone pile of this application is as follows: The operator first uses the hoisting equipment to lift the vibratory crushing stone pile body 3 and make the bottom end of the vibratory crushing stone pile body 3 pass smoothly through the circular through hole 2. Then, the operator starts multiple hydraulic telescopic cylinders 402. The hydraulic telescopic cylinders 402 push the push plate 401 forward. The spring 403 connected to the push plate 401 and the limiting clamp 404 also move forward until the limiting clamp 404 closely contacts the outer surface of the vibratory crushing stone pile body 3, thereby effectively clamping and limiting it to ensure the verticality of the vibratory crushing stone pile body 3 in the initial state.

[0029] In this process, the auxiliary moving roller 13 plays an important role. It provides convenient conditions for the up and down movement of the vibratory crushing pile body 3, which is conducive to the smooth progress of subsequent crushing operations. After the vibratory crushing pile body 3 is successfully clamped, limited, and kept vertical, the operator can control the vibratory crushing pile body 3 to move downward and start the crushing drilling operation. Vibration will be generated when the vibratory crushing pile body 3 is running. This vibration will be transmitted to the limiting clamping plate 404, and the spring 403 can effectively buffer the vibration, avoid the vibration from having an adverse effect on the push plate 401, and ensure the stability of the entire clamping and limiting structure.

[0030] When the laser displacement sensor 405 detects a shift in the vibratory crushing pile body 3 during operation, the laser displacement sensor 405 feeds back a signal to the control element inside the control box 406. The control element then activates the hydraulic telescopic cylinder 402 at the corresponding shift position, causing the hydraulic telescopic cylinder 402 to push the push plate 401 to move, thereby straightening the vibratory crushing pile body 3 in the shifted direction and restoring it to a vertical state. This device can efficiently clamp and limit the vibratory crushing pile body 3 and maintain its verticality. Furthermore, when the vibratory crushing pile body 3 shifts, multiple hydraulic telescopic cylinders 402 can be used to correct it in a timely manner, greatly improving the construction quality and the stability of the project.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
