Description

Technical Field

[0001] This utility model belongs to the technical field of pile foundation engineering equipment, specifically relating to a rotary vibration intelligent pile driver. Background Technology

[0002] With the acceleration of urbanization, the demand for foundation treatment in various construction projects is increasing. Rotary vibratory pile drivers, as an important pile foundation construction equipment, have been widely used in building foundation reinforcement and underground engineering construction. Existing rotary vibratory pile drivers typically rely on the horizontal excitation force generated by the vibratory compactor and the rotational cutting force of the drill bit to drill holes and form piles. However, in practical applications, existing equipment still has many shortcomings in terms of switching between transport and working states, drilling accuracy, and adaptability to different geological conditions.

[0003] For example, in existing technologies, when a piling rig switches to working mode, the lack of a precise angle adjustment mechanism often results in the mast not being perfectly perpendicular to the ground, thus affecting the quality of pile formation. Simultaneously, in softer strata, the inability to effectively displace and expand the soil and rock leads to lower drilling efficiency and pile foundation stability. Furthermore, during power transmission, the drive mechanism design of many devices is not optimized enough, failing to achieve efficient torque transmission, resulting in insufficient rotational force of the vibratory compactor, thereby reducing cutting efficiency and construction speed. Regarding drilling depth control, existing equipment typically adjusts the drill rod length using only a single fixed structure, making precise extension and retraction control difficult, thus limiting the equipment's adaptability to complex geological conditions. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a rotary vibration intelligent pile driver, which can solve the shortcomings of existing pile drivers in terms of angle adjustment, torque transmission, soil and rock cutting efficiency and drilling depth control, thereby significantly improving construction efficiency and pile quality.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A rotary vibration intelligent pile driver includes a body, one end of which is provided with an amplitude-changing mechanism, the movable end of which is connected to a mast, and a power head and an auxiliary positioning component are slidably connected to the side of the mast away from the body.

[0007] A drilling mechanism is rotatably connected between the power head and the auxiliary positioning component;

[0008] The drilling mechanism includes a guide rod located between the power head and the auxiliary positioning component. The bottom end of the guide rod is connected to a vibratory impactor, and the top end of the guide rod is provided with a lifting head.

[0009] The power head is slidably connected to the positioning frame on the outside of the mast. A base is connected to the outside of the positioning frame. A driven gear is rotatably connected inside the base. A spline inner sleeve is connected to the top of the driven gear. A motor is provided on the outside of the positioning frame.

[0010] The motor drives the driven gear to rotate, and the driven gear drives the spline inner sleeve to rotate synchronously.

[0011] Furthermore, the outer side of the vibratory impactor is provided with equally spaced cutting teeth around its axis.

[0012] Furthermore, a cylinder is connected to the side of the mast, and the telescopic end of the cylinder is connected to the power head.

[0013] Furthermore, a first guide wheel and a second guide wheel are respectively provided on the side and top of the mast;

[0014] The top of the lifting head is connected to a steel rope, which passes around the second guide wheel and the first guide wheel in sequence.

[0015] Furthermore, the guide rod includes an inner tube and an outer tube, and the inner tube and the outer tube can slide relative to each other.

[0016] Furthermore, the guide rod cooperates with the spline inner sleeve, and the guide rod rotates synchronously when the spline inner sleeve rotates.

[0017] Furthermore, the positioning frame is symmetrically provided with locking claws on its side, and the locking claws are slidably connected to the mast.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention, by setting up a variable amplitude mechanism, can flexibly switch between the pile driver's transportation state and working state; the variable amplitude mechanism can adjust the angle between the mast and the ground, so that the mast remains vertical during construction, thereby effectively ensuring the verticality and quality of the pile; this design overcomes the problem of pile deviation caused by inaccurate angle adjustment in the prior art, and significantly improves the stability and reliability of construction.

[0020] This invention achieves efficient drilling operations by incorporating a guide rod, vibratory compactor, and cutting teeth into the drilling mechanism. The guide rod is connected to the power head via a spline drive, enabling the vibratory compactor to transmit torque during rotation, while simultaneously working with the cutting teeth to cut the rock and soil. The horizontal excitation force generated by the vibratory compactor can effectively displace and expand the rock and soil in softer strata, avoiding the problem of low drilling efficiency in soft strata with existing equipment, and further improving construction efficiency.

[0021] By adopting a sliding structure design of inner and outer tubes, the guide rod can achieve free extension and retraction adjustment of its length; combined with the power head drive system, the drilling depth can be precisely controlled according to construction needs; this structure effectively solves the problem of inaccurate drilling depth control in existing technologies, enabling the equipment to adapt to construction needs under different geological conditions.

[0022] Guide wheels are provided on the side and top of the mast in this utility model. Through the cooperation of the guide wheels and the steel rope, the lifting head and guide rod can be precisely guided. This structure makes the adjustment of drilling depth smoother and avoids the jamming problem caused by uneven force during the lifting of the guide rod. This design further improves drilling efficiency and the reliability of depth control.

[0023] By incorporating locking claws and a symmetrical structural design on the side of the positioning frame, the power head receives additional positioning support as it slides on the mast. This design effectively prevents the power head from shifting during operation, improving the accuracy of drilling operations. Simultaneously, the transmission structure between the positioning frame and the driven gear and spline inner sleeve inside the base ensures efficient power transmission to the guide rod, solving the problem of insufficient power transmission efficiency in existing equipment.

[0024] By evenly distributing cutting teeth on the outside of the vibratory compactor, the vibratory compactor has a stronger crushing capacity when cutting rock and soil; the even distribution of cutting teeth can balance the working load of the vibratory compactor, further improving the efficiency and stability of drilling; this design overcomes the shortcomings of insufficient cutting force and low rock and soil crushing efficiency of existing technologies.

[0042] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0043] Example 1:

[0044] See Figure 1-6 A rotary vibration intelligent pile driver includes a body 1. An amplitude-changing mechanism 2 is installed at one end of the body 1. The amplitude-changing mechanism 2 is connected to a mast 3 via its movable end. The amplitude-changing mechanism 2 can adjust the angle of the mast 3 to ensure that the mast 3 is perpendicular to the ground, thereby ensuring the quality of pile formation. A power head 5 and an auxiliary positioning component 7 are slidably connected to the side of the mast 3 away from the body 1. The power head 5 drives a drilling mechanism 6, while the auxiliary positioning component 7 precisely guides the movement of the drilling mechanism 6. The drilling mechanism 6, which is rotatably connected to the power head 5, forms an integral structure. The drilling mechanism 6 can rotate under the drive of the power head 5, thereby achieving cutting operations on the soil and rock.

[0045] See Figure 1-6The drilling mechanism 6 includes a guide rod 61 located between the power head 5 and the auxiliary positioning component 7. The guide rod 61 is a key transmission component for drilling. The bottom end of the guide rod 61 is connected to a vibratory compactor 63. During operation, the vibratory compactor 63 can generate a horizontal excitation force to squeeze and expand the softer soil and rock to both sides to improve drilling efficiency. The top end of the guide rod 61 is provided with a lifting head 62. The lifting head 62 cooperates with the guide wheel system of the mast 3 through a steel rope to realize the vertical displacement of the guide rod 61, thereby controlling the drilling depth.

[0046] See Figure 1-6 The power head 5 is slidably connected to the positioning frame 51 on the outside of the mast 3. The positioning frame 51 is used to guide the power head 5 to move along the mast 3 to complete the drilling operation. The outer side of the positioning frame 51 is connected to the base 52. The driven gear 55 is rotatably connected to the inside of the base 52 through the bearing. The driven gear 55 is used to transmit power to drive the guide rod 61 to rotate. The top of the driven gear 55 is connected to the spline inner sleeve 54. The spline inner sleeve 54 cooperates with the spline structure of the guide rod 61 to achieve efficient power transmission. The outer side of the positioning frame 51 is also equipped with a motor 53. The motor 53 is the power source of the entire drive system. By driving the driven gear 55 to rotate, it drives the spline inner sleeve 54 and the guide rod 61 to rotate synchronously.

[0047] See Figure 1-3 The vibratory compactor 63 has cutting teeth 631 evenly distributed around its axis on its outer side. The cutting teeth 631 are the key cutting components of the vibratory compactor 63. During drilling operations, the cutting teeth 631 cut the rock and soil through rotational motion. Combined with the horizontal excitation force generated by the vibratory compactor 63, the rock and soil can be quickly crushed and removed, thereby improving drilling efficiency.

[0048] See Figure 1 A cylinder 4 is connected to the side of the mast 3, and the telescopic end of the cylinder 4 is connected to the power head 5. The cylinder 4 can adjust the height and position of the power head 5 through telescopic movement, ensuring that the connection between the power head 5 and the drilling mechanism 6 is accurate, thereby further improving the stability and efficiency of drilling.

[0049] See Figure 1-2 The mast 3 is provided with a first guide wheel 31 and a second guide wheel 32 on its side and top, respectively. The first guide wheel 31 and the second guide wheel 32 provide a guiding path for the steel rope, ensuring that the steel rope can smoothly transmit the tension. The top of the lifting head 62 is connected to a steel rope, which passes around the second guide wheel 32 and the first guide wheel 31 in sequence. The lifting head 62 and the guide rod 61 are raised and lowered by the action of the guide wheel system, thereby accurately controlling the drilling depth.

[0050] See Figure 2-4The guide rod 61 includes an inner tube 611 and an outer tube 612, which are sliding fit structures. The inner tube 611 and the outer tube 612 can slide to adjust the extension and retraction of the guide rod 61, thereby controlling the accuracy of the drilling depth and adapting to the construction needs of different geological conditions.

[0051] See Figure 2-6 The guide rod 61 cooperates with the spline inner sleeve 54. The rotational motion of the spline inner sleeve 54 is efficiently transmitted to the guide rod 61 through the spline transmission structure. When the spline inner sleeve 54 rotates, the guide rod 61 can rotate synchronously, thereby driving the vibratory punch 63 and the cutting tooth 631 to perform cutting operations.

[0052] See Figure 1 and Figure 6 The positioning frame 51 has symmetrically arranged locking claws 511 on its side, which are slidably connected to the mast 3. The design of the locking claws 511 can provide additional positioning support during the sliding of the power head 5, preventing the power head 5 from shifting on the mast 3, thereby further improving the accuracy and stability of the drilling operation.

[0053] Example 2:

[0054] This embodiment provides a rotary vibration intelligent pile driver. During construction, the machine body 1 provides a stable foundation and mobility for the rotary vibration intelligent pile driver. The self-propelled system of the machine body 1 consists of a motor, four-wheel drive wheels, track rollers, support rollers, tension rollers, and combined track plates; this structure ensures the safety and flexibility of the equipment, enabling free movement and precise positioning on the construction site. The power system of the machine body 1 includes a diesel internal combustion engine, a power head motor, a travel motor, a hydraulic oil pump, etc., providing the necessary power to each component; the control system realizes comprehensive monitoring and operation of the equipment through the operation panel and electrical control box, while the monitoring equipment provides alarms and operational feedback to ensure safety and timely response during construction.

[0055] The luffing mechanism 2 can adjust the verticality and tilt angle between the mast 3 and the ground, thereby enabling a smooth switch between construction and transportation states, improving construction adaptability and equipment transportation convenience.

[0056] The mast 3 and the luffing mechanism 2 provide guidance and also provide reaction force support for the power head 5.

[0057] The guide rod 61 has a multi-section structure, and its length can be flexibly adjusted according to construction needs to adapt to construction requirements at different depths. During the drilling process, the locking point design between the power head 5 and the guide rod 61 allows the equipment to lock and unlock flexibly; the downward pressure of the power head 5 is transmitted to the vibratory compactor 63 and the cutting teeth 631 through the guide rod 61, ensuring efficient crushing of the soil and rock layers. The vibratory compactor 63 is driven by a hydraulic system. In soft strata, it diffuses the soil and rock through horizontal vibration force. In hard strata, it works with the cutting teeth 631 to cut and expand the crushed soil and rock, ultimately forming a hole.

[0058] This embodiment of the rotary vibratory intelligent pile driver integrates lifting, drilling, hydraulic, and pipe winding functions into one unit, simplifying construction procedures, improving construction efficiency, and reducing construction costs. The equipment's design ensures adaptability and reliability in complex geological formations and ultra-deep pile construction, making it an ideal choice for modern pile foundation engineering.

[0059] The working principle of this utility model is as follows:

[0060] When in use, the machine body 1 moves to the predetermined drilling position, and the angle of the mast 3 is adjusted by the luffing mechanism 2 to make the mast 3 perpendicular to the ground to be drilled, so as to ensure the quality of pile formation. At the same time, the luffing mechanism 2 can realize the switching between working state and transportation state of the pile driver.

[0061] Then, under the action of the vibratory compactor 63, a horizontal excitation force is generated, which can squeeze and expand the rock and soil to both sides for softer strata;

[0062] During the drilling process, the power head 5 drives the guide rod 61 to rotate, and the guide rod 61 drives the vibratory compactor 63 to rotate. During the rotation process, torque is transmitted simultaneously. Finally, the cutting teeth 631 set on the front end of the vibratory compactor 63 cut the rock and soil, thereby improving the drilling efficiency.

[0063] When the power head 5 is running, the positioning frame 51 drives the driven gear 55 inside the base 52 to rotate. During the rotation of the driven gear 55, it will drive the spline inner sleeve 54 connected to the top of the driven gear 55 to rotate synchronously. The spline inner sleeve 54 and the guide rod 61 are engaged with each other. When the spline inner sleeve 54 rotates, it will drive the guide rod 61 to rotate synchronously.

[0064] During drilling, the expansion and contraction of the inner tube 611 and the outer tube 612 can be controlled through the hole, thereby controlling the drilling depth.

[0065] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
