Description

Technical Field

[0001] The present invention relates to the field of pile hole wall cleaning devices, and particularly to an adaptive radial telescopic device for cleaning the hole wall of rock-socketed piles. Background Art

[0002] During the construction of rock-socketed piles, when the slurry-supported wall technology is adopted, the colloidal particles in the slurry continuously deposit on the surface of the hole wall formation, forming a smooth slurry surface layer. This surface layer will greatly weaken the bonding interface effect between the pile body and the surrounding rock and soil masses, resulting in a reduction rate of pile side friction resistance reaching 20% - 40%, seriously affecting the design value of the vertical bearing capacity of the pile foundation. Although the existing technology improves the slurry performance by adjusting the slurry specific gravity or adding dispersants, there are still problems such as insufficient control accuracy of the slurry thickness and low hole cleaning efficiency in complex formations, leading to an extended construction period and increased comprehensive costs.

[0003] Currently, the slurry cleaning of the rock-socketed pile hole wall mainly uses devices such as air-lift reverse circulation, high-pressure pumping, or hydrocyclone separation. However, the existing technology has the following technical defects: 1. Insufficient equipment applicability: Most of the existing devices are of general-purpose design and are difficult to meet the construction requirements of large-diameter and ultra-deep holes of rock-socketed piles; 2. Poor cleaning efficiency and effect: The existing devices have insufficient peeling ability for the mud skin on the hole wall. Especially in complex hole wall shapes, such as different hole wall diameters and irregular shapes, traditional cleaning techniques are difficult to completely remove the mud skin, and the residual mud skin thickness often exceeds the specification requirements, affecting the bonding strength between the pile foundation and the rock and soil masses.

[0004] In summary, the existing hole wall mud skin cleaning devices have significant deficiencies in adaptability, cleaning efficiency, and effect, and there is an urgent need for a new cleaning device with strong adaptability and cleaning ability. Summary of the Invention

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0044] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0045] Refer to Figure 1-2 , the present invention provides a self-adaptive radial telescopic device for cleaning the hole wall of a rock-socketed pile, including:

[0046] A mounting frame 1, the mounting frame 1 is a circular disc structure, and a plurality of groups of sliding grooves 3 are circumferentially and equally spaced on the outer peripheral surface of the mounting frame 1;

[0047] A hoisting frame, which is fixed at the central position of the top surface of the mounting frame 1;

[0048] The telescopic arms are provided with several groups. The several groups of telescopic arms are respectively slidably connected in the chute 3, and a compression assembly is arranged between the end of the telescopic arm and the bottom wall of the chute 3;

[0049] The arc-shaped plates 2 are provided with several groups. The several groups of arc-shaped plates 2 are combined to form an annular structure. The inner peripheral surfaces of the arc-shaped plates 2 are respectively fixed to the telescopic arms, and the axis of the arc-shaped plate 2 is parallel to the axis of the mounting frame 1;

[0050] The cleaning assembly is installed on the outer peripheral surface of the arc-shaped plate 2;

[0051] The pressure monitoring module is installed on the outer peripheral surface of the arc-shaped plate 2. The pressure monitoring module and the telescopic arm are both connected to the controller;

[0052] The winding assembly is installed on the hoisting frame. A steel wire rope is fixed to one end of the telescopic arm close to the compression assembly. The steel wire rope passes through the bottom wall of the chute 3 and the hoisting frame and is wound around the winding assembly.

[0053] The working process of the present invention includes the following steps:

[0054] 1) Connect the device to an external hoisting device through the hoisting frame, and use the hoisting device to lower the device to a specified position in the rock socket hole. At this time, the telescopic arms are in a contracted state under the action of the compression assembly, and the diameter of the annular structure formed by the arc-shaped plates 2 is smaller, which is convenient for the device to be smoothly lowered into the hole.

[0055] 2) When the device is lowered to a suitable position in the hole, the controller controls the winding assembly to work, and the winding assembly starts to loosen the steel wire rope. As the steel wire rope is loosened, the telescopic arms slide outward along the chute 3 on the outer peripheral surface of the mounting frame 1 under the elastic force of the compression assembly, thereby pushing the arc-shaped plates 2 to move outward, so that the diameter of the annular structure formed by the arc-shaped plates 2 gradually increases until the outer peripheral surface of the arc-shaped plates 2 is in close contact with the hole wall.

[0056] 3) After the arc-shaped plates 2 are in close contact with the hole wall, the cleaning assembly installed on the outer peripheral surface of the arc-shaped plates 2 starts to work to clean the hole wall. During the cleaning process, the pressure monitoring module continuously monitors the pressure between the outer peripheral surface of the arc-shaped plates 2 and the hole wall, and transmits the pressure data to the controller. The controller dynamically adjusts the working state of the winding assembly according to the received pressure data. If the pressure is too high, the controller controls the winding assembly to appropriately tighten the steel wire rope, so that the telescopic arms contract inward, reducing the pressure between the arc-shaped plates 2 and the hole wall; if the pressure is too low, the controller controls the winding assembly to further loosen the steel wire rope, allowing the telescopic arms to continue to extend outward, increasing the pressure between the arc-shaped plates 2 and the hole wall, ensuring that the cleaning assembly always cleans the hole wall with an appropriate pressure and ensuring the cleaning effect.

[0057] 4) After the hole wall cleaning work is completed, the controller controls the winding component to tighten the steel wire rope. The steel wire rope pulls the telescopic arm to slide inward along the chute 3. The telescopic arm drives the arc-shaped plate 2 to contract inward, reducing the diameter of the ring structure formed by the arc-shaped plate 2 and disengaging from the contact with the hole wall. Subsequently, the device is lifted and recovered from the hole using a hoisting device.

[0058] For a further optimized solution, the lifting frame includes:

[0059] A lifting column 4, which is arranged on the top surface of the mounting frame 1 and is coaxially arranged with the mounting frame 1;

[0060] Connecting rods 5, several groups of connecting rods 5 are arranged circumferentially and equidistantly at the bottom of the lifting column 4 and are fixedly connected to the lifting column 4. The axis of the connecting rod 5 is arranged at an obtuse angle to the axis of the lifting column 4;

[0061] A hook 6, which is fixed at the top of the lifting column 4.

[0062] During hoisting, an external hoisting device is connected to the device through the hook 6. The lifting column 4 plays a major load-bearing role. Since the lifting column 4 is coaxially arranged with the mounting frame 1, the stability of the device during lowering is ensured. The connecting rods 5 are arranged circumferentially and equidistantly and the axis of the connecting rod 5 is at an obtuse angle to the axis of the lifting column 4. On the one hand, the connection strength between the lifting column 4 and the mounting frame 1 is enhanced. On the other hand, during the lowering process of the device, the connecting rods 5 can play a certain guiding role, enabling the device to enter the rock-socketed pile hole more smoothly.

[0063] For a further optimized solution, the cleaning component includes:

[0064] A mounting seat 7, a groove is provided on the outer peripheral surface of the arc-shaped plate 2, and the mounting seat 7 is slidably connected in the groove;

[0065] A wire brush, which is fixed on the mounting seat 7;

[0066] A spring Ⅰ 8, which is fixed between the mounting seat 7 and the bottom wall of the groove;

[0067] A directional roller 9, which is installed on the arc-shaped plate 2 and is arranged corresponding to the mounting seat 7.

[0068] When the arc-shaped plate 2 contacts the hole wall, the wire brush first contacts the hole wall and conducts cleaning. Since the mounting seat 7 is slidably connected in the groove and there is a spring I 8 between it and the bottom wall of the groove, during the cleaning process, the wire brush can adaptively expand and contract according to the local unevenness of the hole wall. The spring I 8 plays a role in buffering and adjusting the pressure, enabling the wire brush to always contact the hole wall with an appropriate pressure to ensure the cleaning effect. The directional roller 9 is arranged corresponding to the mounting seat 7. During the up and down movement of the device, the directional roller 9 rolls along the hole wall, playing a role in guiding and reducing friction. At the same time, the pressure sensor between the directional roller 9 and the arc-shaped plate 2 can monitor the pressure between the arc-shaped plate 2 and the hole wall in real time.

[0069] For a further optimized solution, the pressure monitoring module includes:

[0070] A pressure sensor, which is installed between the directional roller 9 and the arc-shaped plate 2 and is used to monitor the force on the arc-shaped plate 2.

[0071] The pressure sensor is installed between the directional roller 9 and the arc-shaped plate 2. When the arc-shaped plate 2 is subjected to the pressure of the hole wall, the pressure is transmitted to the pressure sensor through the directional roller 9. The pressure sensor converts the pressure signal into an electrical signal and transmits it to the controller. The controller performs adaptive adjustment on the device according to the received pressure data.

[0072] For a further optimized solution, the telescopic arm includes:

[0073] A hydraulic telescopic rod 10, which is slidably connected in the chute 3, and the end of the hydraulic telescopic rod 10 is fixed to the inner peripheral surface of the arc-shaped plate 2.

[0074] In the initial state, the spring II 11 is in a constant compression state, contracting the hydraulic telescopic rod 10 in the chute 3. When the wire rope is relaxed by the winding component, the elastic force of the spring II 11 pushes the hydraulic telescopic rod 10 to slide outward along the chute 3, causing the arc-shaped plate 2 to expand outward until it contacts the hole wall. During the cleaning process, the controller can further finely adjust the telescopic length of the hydraulic telescopic rod 10 by controlling the hydraulic system according to the pressure data fed back by the pressure monitoring module to achieve precise control of the pressure between the arc-shaped plate 2 and the hole wall.

[0075] For a further optimized solution, the compression component includes:

[0076] A spring II 11, which is fixed between the hydraulic telescopic rod 10 and the bottom wall of the chute 3, and the spring II 11 is in a constant compression state.

[0077] Spring II 11 is always in a compressed state, providing an outward elastic force for the hydraulic telescopic rod 10, so that after the device is lowered to a suitable position in the hole, the hydraulic telescopic rod 10 can automatically extend outward and push the arc-shaped plate 2 into contact with the hole wall. During the cleaning process, the elastic force of Spring II 11 can also play a buffering role. When there are local protrusions on the hole wall, the hydraulic telescopic rod 10 can appropriately contract against the elastic force of Spring II 11 to avoid damage to the device and the hole wall caused by excessive pressure.

[0078] For a further optimized solution, the winding assembly includes:

[0079] A worm, which is rotatably connected to the hoisting column 4, and a handle 12 is installed at one end of the worm;

[0080] A worm gear, which is rotatably connected to the hoisting column 4, and is in transmission cooperation with the worm;

[0081] A winding roller, which is fixed on the worm gear. A guiding hole is provided on the hoisting column 4, and the steel wire rope passes through the guiding hole and is fixed to the winding roller.

[0082] When it is necessary to adjust the telescopic state of the arc-shaped plate 2, the operator rotates the worm through the handle 12, the worm drives the worm gear to rotate, and the worm gear drives the winding roller to rotate. When the winding roller rotates, the steel wire rope is tightened or loosened, thereby controlling the telescopic movement of the hydraulic telescopic rod 10. The transmission mode of the worm and the worm gear has self-locking property. When the handle 12 stops rotating, the winding roller can maintain its current position to ensure the stable telescopic length of the hydraulic telescopic rod 10.

[0083] For a further optimized solution, a tarpaulin 13 is wrapped around the end of the hydraulic telescopic rod 10, and the tarpaulin 13 is fixed between the arc-shaped plate 2 and the mounting frame 1.

[0084] The tarpaulin 13 is fixed between the arc-shaped plate 2 and the mounting frame 1. As the hydraulic telescopic rod 10 extends and retracts, the tarpaulin 13 can automatically unfold or contract, playing a role in protecting the hydraulic telescopic rod 10 and preventing impurities such as mud and gravel in the hole from entering the chute 3 and affecting the normal sliding of the hydraulic telescopic rod 10.

[0085] For a further optimized solution: The mounting frame 1, the hoisting column 4, and the connecting rod 5 are made of high-strength alloy steel, such as 42CrMo, which has good strength and toughness and can withstand the weight of the device itself and various forces during the cleaning process.

[0086] The arc-shaped plate 2 is made of wear-resistant and corrosion-resistant stainless steel material, such as 304 stainless steel, to ensure that it can be used for a long time in the complex environment in the hole without damage.

[0087] The hydraulic telescopic rod 10: The cylinder body is made of seamless steel pipe, the material is 20# steel, the piston rod is made of 45# steel and is quenched and tempered, and the surface is chrome-plated to improve wear resistance and corrosion resistance.

[0088] Wire brush: The bristles are made of high-strength steel wire, and the brush handle is made of stainless steel to ensure the cleaning effect and service life.

[0089] Spring I 8 and Spring II 11: Made of 60Si2Mn spring steel, having good elasticity and fatigue strength.

[0090] Tarpaulin 13: Select high-strength, wear-resistant and waterproof nylon tarpaulin 13, which can effectively protect the hydraulic telescopic rod 10.
