Description

Technical Field

[0001] The present invention relates to the technical field of pile drivers, and more particularly to a three-axis mixing pile driver with a deviation correction function. Background Art

[0002] The three-axis mixing pile driver is a type of long spiral pile driver with three spiral drill holes. During construction, the three spiral drill holes are constructed downward at the same time. It is an effective form of soft foundation treatment. The mixing pile driver is used to spray cement into the soil and fully mix it, so that a series of physical and chemical reactions occur between the cement and the soil, which hardens the soft soil and improves the foundation strength.

[0003] Three-axis mixing pile machines play an important role in foundation pit retaining projects. One type does not have steel sections inserted in the middle and is only used as a water stop. If retaining soil is required, it should be combined with other processes; the other type is to insert H-shaped steel into the mixing pile body (commonly known as the SMW method), which can serve as both a water stop and a retaining wall, and is suitable for foundation pits with shallower depths. The existing three-axis mixing pile machines still have some shortcomings when in use. One of them is that some of the existing three-axis mixing pile machines do not have a correction function. When in use, they may encounter hard objects, causing the three-axis mixing pile machines to deflect during the construction process, which in turn makes it easy for gaps to appear in the formed water-stop structure, thereby affecting the overall water-stop stability of the formed water-stop structure. Therefore, a structure is provided to solve the problem that some of the existing three-axis mixing pile machines do not have a good correction function.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Invention

DETAILED DESCRIPTION

[0025] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0026] A three-axis pile mixing machine with a deviation correction function, such as Figure 1 As shown, it includes a pile machine body 1 and three drill rods 2 that are transmission-connected to the pile machine body 1. The pile machine body 1 is provided to achieve stable support and position limiting of each part. At the same time, under the driving action of the pile machine body 1, the three drill rods 2 can be driven, thereby achieving stable realization of the construction function of the entire structure. The three drill rods 2 are all arranged vertically and distributed in an array. The drill rod 2 includes a spiral section 3 at the bottom and a smooth section 4 fixedly connected to the top of the spiral section 3. The three drill rods 2 located at the connection between the spiral section 3 and the smooth section 4 are sleeved with an auxiliary correction structure that is slidingly connected to the pile machine body 1. The auxiliary correction structure is provided with a reminder part for reminding the drill rod 2 to deviate. Under the action of the reminder part, the operator can be reminded in time when the drill rod 2 deviates, so that the operator can open the auxiliary correction structure in time, so that the auxiliary correction structure can stably realize its auxiliary correction function, realize stable correction of the deviated drill rod 2, and thereby make the construction process and construction effect of the drill rod 2 more stable.

[0027] like Figure 1 and Figure 5As shown, the reminder part includes a plurality of switches which are set on the drill rod 2 and fixedly connected to the top surface of the auxiliary correction structure. The reminder part also includes an alarm 5 fixedly connected to the top of the auxiliary correction structure and electrically connected to the plurality of switches. The reminder part also includes an alarm light 6 fixedly connected to the top of the auxiliary correction structure and electrically connected to the plurality of switches. The input section of the switch is connected to the power supply through an electric wire, and the output section of the switch is connected to the alarm 5 and the alarm light 6 through an electric wire. After the alarm 5 is powered on, a sound will be generated to warn, and after the alarm light 6 is powered on, a flash will be generated to warn. The dual warning of sound and light makes the reminder effect of the reminder part more stable, so that the operator can find the deviation of the drill rod 2 more promptly, realize timely correction of the drill rod 2, and thus ensure the more stable construction quality of the overall structure.

[0028] like Figure 1 and Figure 5 As shown, when the drill rod 2 is not deflected, the switch is in an open circuit state, and the alarm 5 and the alarm light 6 are both in a power-off state. When the drill rod 2 is deflected, the drill rod 2 will exert a force on the switch, pushing the switch to gradually close. After the switch is closed, the alarm 5 and the alarm light 6 are both in a power-on state. The alarm 5 sounds and the alarm light 6 flashes to warn, thereby providing a double reminder to the operator, allowing the operator to promptly discover the deflection of the drill rod 2, and then promptly start the auxiliary correction structure to correct the deviation, thereby achieving stable correction of the deflected drill rod 2, reducing the impact of the deflection of the drill rod 2 on the overall construction effect of the structure, and improving the overall construction effect of the structure.

[0029] like Figure 1 、 Figure 5 and Figure 6As shown, the switch includes a first fixing ring 7 fixedly connected to the top surface of the auxiliary correcting structure. The first fixing ring 7 is fixed to the top of the auxiliary correcting structure by welding. The inner wall of the first fixing ring 7 is fixedly connected with elastic deformation rings 8 distributed up and down by adhesive bonding. The elastic deformation rings 8 are set to EPDM rubber. The characteristics of good weather resistance, good insulation and good elasticity of this type of material are used to ensure that the elastic deformation rings 8 have good and stable elastic deformation performance, insulation and weather resistance, so that the service life and use stability of the elastic deformation rings 8 are better. A ring groove 9 is provided between the two elastic deformation rings 8. The inner sides of the two elastic deformation rings 8 are fixedly connected with the first sliding ring 10 by means of adhesive bonding. The distance between the first sliding ring 10 and the drill rod 2 is greater than zero. This setting ensures that when the drill rod 2 does not deviate, the first sliding ring 10 and the drill rod 2 are in a non-contact state, reducing the impact of the drill rod 2 driving process on the first sliding ring 10, thereby ensuring that the position of the first sliding ring 10 and the function it can produce are more stable. The outer ring wall of the first sliding ring 10 is fixedly connected with a connecting ring body 11 that passes through the yield ring groove 9 by welding. The distance between the connecting ring body 11 and the first fixed ring 7 is greater than zero and can be As the drill rod 2 deviates to the inner ring wall of the first fixed ring 7, the connecting ring body 11 and the first fixed ring 7 are in a non-contact state under the separation and support of the elastic deformation ring 8. During the deviation of the drill rod 2, it will gradually abut against the inner ring wall of the first sliding ring 10 and push the first sliding ring 10 to move. During the movement of the first sliding ring 10, it will drive the connecting ring body fixedly connected to it to move, so that the connecting ring body gradually moves to abut against the first fixed ring 7. During this process, the first sliding ring 10, the connecting ring body 11 and the first fixed ring 7 are connected to each other, realizing the stable closure of the switch, and the first fixed ring 7 and The power supply is connected through wires, and the first sliding ring 10 is connected to the alarm 5 and the alarm light 6 through wires. Therefore, when the switch is closed, the alarm 5 and the alarm light 6 will be stably powered to realize the warning function of the alarm 5 and the alarm light 6. When the drill rod 2 is corrected and gradually reset, the drill rod 2 gradually relaxes its pressure and push on the first sliding ring 10. Under the action of the elastic force generated by the elastic deformation ring 8, the elastic deformation ring 8 will gradually push the first sliding ring 10 and the connection ring away from the first fixed ring 7, realizing the state of the switch being disconnected, and then realizing the power off of the alarm 5 and the alarm light 6.

[0030] like Figure 1-Figure 5As shown, a vertically arranged first support plate 12 is fixedly connected to the pile machine body 1 by welding and bolt connection. A vertically arranged T-shaped guide groove 13 is provided on the first support plate 12. The auxiliary correction structure includes a T-shaped guide block 14 slidably connected in the T-shaped guide groove 13. With the help of the joint action of the T-shaped guide block 14 and the T-shaped guide groove 13, the sliding connection between the auxiliary correction structure and the first support plate 12 and the pile machine body 1 is achieved. With the help of the smooth sliding process of the T-guide block in the T-shaped guide groove 13, the sliding process between the auxiliary correction structure and the pile machine body 1 is ensured to be more stable and smooth, ensuring that the position of the auxiliary correction structure and the correction function it can produce are more stable. The T-shaped guide block 14 is fixedly connected to the upper and lower distributions by welding. The second support plate 15 is used to achieve stable support and limitation of each part with the help of the provided second support plate 15. The reminder part is at the top surface of the second support plate 15 at the top. A first through hole 16 is penetrated on the second support plate 15 and is sleeved on the outside of the smooth section 4 and has a diameter larger than the smooth section 4. The bottom of the smooth section 4 is fixedly connected to a support ring 17 that is against the bottom surface of the second support plate 15 on the bottom side by welding. With the help of the provided support ring 17, the drill rod 2 will drive the support ring 17 fixedly connected to it to move during the movement. During the movement of the support ring 17, the second support plate 15 against it will be driven up and down, thereby promoting the movement of the auxiliary correcting structure, thereby reducing the influence of the setting of the auxiliary correcting structure on the movement process of the drill rod 2.

[0031] like Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the auxiliary deviation-correcting structure also includes a plurality of first fixed tubes 18 fixedly connected to the top surface of the second support plate 15 on the bottom side, and the first fixed ring 7 is fixed to the top surface of the second support plate 15 by welding. The plurality of first fixed tubes 18 are concentrically arranged with the first through hole 16, and the inner side of the first fixed tube 18 is provided with a first sliding tube 19 sleeved on the outer side of the smooth section 4. The top of the first fixed tube 18 is fixedly connected with a limiting ring that abuts against the top of the first sliding tube 19. The distance between the inner ring wall of the limiting ring and the smooth section 4 is greater than zero, and the inner ring wall is coplanar with the inner tube wall of the first sliding tube 19. Under the action of the provided limiting ring, the position of the first sliding tube 19 can be stably limited to ensure that the first sliding tube 19 can be stably in the first fixed tube 1 8, thereby ensuring that the correction function of the auxiliary correction structure can be stably realized, the inner tube diameter of the first sliding tube 19 is larger than the diameter of the smooth section 4, the diameter of the first through hole 16 is larger than the diameter of the smooth section 4 and smaller than the outer tube diameter of the first sliding tube 19, the inner diameter of the first fixed tube 18 is larger than the outer diameter of the first sliding tube 19, and the interior of the first sliding tube 19 is fixedly connected with a plurality of groups of first connecting plates 20 distributed circumferentially by welding. The first connecting plates 20 of the same group are two symmetrically arranged pieces and the length is consistent with the length of the first sliding tube 19. The first connecting plates 20 of the same group are rotatably connected with a plurality of tightening balls 21 distributed in an array along the length direction thereof, the rotation axis of the tightening balls 21 is horizontally arranged, and the tightening balls 21 and the first connecting plates 20 are matched with the shaft holes to realize The rotation connection is now formed, the tightening ball 21 is against the outer wall of the smooth section 4, and a plurality of first guide grooves 22 distributed circumferentially are provided on the inner wall of the first fixed tube 18. The length direction of the first guide groove 22 is vertically arranged, and the first guide groove 22 is provided with a C-shaped support frame 23 that slides in the horizontal direction. The opening of the C-shaped support frame 23 faces the first sliding tube 19 and is rotatably connected with a tightening roller 24 that can be against the outer tube wall of the first sliding tube 19. The tightening roller 24 and the C-shaped support frame 23 are rotatably connected by means of an axial hole, and the rotation axis of the tightening roller 24 is vertically arranged. A horizontally arranged driving rod 25 is fixedly connected to the C-shaped support frame 23 on the side away from the tightening roller 24 by welding, and a driving rod 25 is provided on the groove wall of the first guide groove 22. 25 passes through the second guide groove 26 of the first fixed tube 18, and the cross-sectional shapes of the driving rod 25 and the second guide groove 26 are both set to be square. The cross-sectional area of ​​the second guide groove 26 is consistent with the cross-sectional area of ​​the driving rod 25. This setting ensures that the second guide groove 26 can achieve stable guiding and limiting effects on the sliding process of the driving rod 25, so that the sliding process and driving effect of the driving rod 25 are better. The auxiliary correction structure also includes a driving part for synchronously driving a plurality of pressing rollers 24 to press against the first sliding roller. Under the action of the driving part, the set driving rod 25 can be driven to slide in the horizontal direction to approach the smooth section 4. In this process, the driving rod 25 and the gradually pushed C-shaped support frame 23 and the pressing roller 24 rotatably connected thereto gradually approach the smooth section 4 in the horizontal direction.During this process, the pressing roller 24 will gradually press against the first sliding tube 19, so that the first sliding tube 19 is gradually in a state of being collinear with the first through hole 16, thereby enabling the first sliding tube 19 to stably drive the pressing ball 21 connected thereto for rotation to press against the drill rod 2 and gradually realize the correction function of the auxiliary correction structure. Since the driving part will synchronously drive the plurality of first sliding rollers, under the driving action of the driving part, the pressing roller 24 can stably press against the outer wall of the first sliding tube 19, so that the first sliding tube 19 is gradually in a state of coinciding with the center axis of the first through hole 16, thereby realizing stable correction of the deviated drill rod 2. At the same time, since the pressing roller 24 and the pressing ball 21 are both in a state of rotational connection, and the rotation axis of the pressing roller 24 is vertically arranged, and the rotation axis of the pressing ball 21 is horizontally arranged, this arrangement can reduce the influence of the auxiliary correction structure on the construction process of the drill rod 2.

[0032] like Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the driving part includes a telescopic driving member 27 that is vertically arranged and fixedly connected to the top surface of the second support plate 15 at the top. The telescopic driving member 27 is arranged as an electric telescopic rod. The electric telescopic rod has the characteristic of a smooth and smooth driving process to ensure that the telescopic driving member 27 has a good and stable telescopic driving effect. The driving end of the telescopic driving member 27 passes through the bottom of the second support plate 15, and the bottom of the telescopic driving member 27 is fixedly connected to a driving plate 28 that is slidably connected to the second support plate 15 at the bottom by welding, so that the telescopic end of the driving plate 28 can stably drive the driving plate 28 to move when moving, thereby realizing the driving function of the driving plate 28. A plurality of second through holes are opened through the driving plate 28 and are opposite to the first through holes 16. 29, the diameter of the second through hole 29 is larger than the diameter of the smooth section 4, and a driving tube 30 concentrically arranged with the second through hole 29 is fixedly connected to the bottom of the driving plate 28, and the driving tube 30 is sleeved on the outside of the first fixed tube 18. By sleeved on the outside of the first fixed tube 18, the first fixed tube 18 can achieve a stable guiding and limiting effect on the sliding process of the driving tube 30, so that the sliding process of the driving tube 30 relative to the first fixed tube 18 is more stable and smooth, thereby making the sliding process of the driving tube 30 and the driving plate 28 more stable and smooth, making the process of the telescopic driving member 27 driving the driving plate 28 and the driving tube 30 more stable, so that the overall driving effect of the driving part can be stably achieved, ensuring that the driving part can stably drive the auxiliary The correction structure corrects the deviation according to needs. A plurality of first driving grooves 31 distributed circumferentially are provided on the inner wall of the driving tube 30. The bottom side of the first driving groove 31 passes through the driving tube 30 and is provided for the driving rod 25 to pass through. The width of the first driving groove 31 is consistent with the width of the driving rod 25. This arrangement enables the first driving groove 31 to achieve a stable guiding and limiting effect on the sliding process of the driving rod 25 passing therethrough, so that the sliding process of the driving rod 25 in the first driving groove 31 is more stable and smooth. The driving rod 25 can pass into the first driving groove 31 along the bottom of the first driving groove 31. A second driving groove 32 is provided above the first driving groove 31 and is interconnected with the first driving groove 31 and is provided for the driving rod 25 to pass through. The groove depth of the second driving groove 32 is less than that of the first driving groove 31. A first pushing inclined surface 33 is provided at the connection between the first driving groove 31 and the second driving groove 32, and a second pushing inclined surface 34 is provided above the driving rod 25. Under the joint action of the first pushing inclined surface 33 and the second pushing inclined surface 34, the driving rod 25 can stably slide from the first driving groove 31 to the second driving groove 32 under the guidance of the first pushing inclined surface 33 and the second pushing inclined surface 34. Since the groove depth of the second driving groove 32 is smaller than that of the first driving groove 31 and the second driving groove 32 in the first driving groove 31 are both opened on the inner wall of the driving tube 30, the driving tube 30 can push the driving rod 25 to move toward the center of the fixed tube, thereby realizing stable driving of the horizontal sliding process of the driving rod 25, thereby realizing the driving function of the entire driving part.

[0033] like Figure 3-Figure 5 As shown, the bottom of the driving plate 28 is fixedly connected to a plurality of symmetrically arranged sliding rods 35 by welding, and a plurality of sliding holes 36 for the sliding rods 35 to penetrate and slide are provided on the second support plate 15 on the bottom side. The sliding of the sliding rods 35 in the sliding holes 36 is used to achieve stable guidance and limitation of the sliding process of the driving plate 28, so that the sliding process of the driving plate 28 is more stable and smooth, thereby ensuring that the driving process of the driving plate 28 and the driving function of the driving part as a whole are more stable, so that the driving part can stably drive the auxiliary correction structure to realize the correction function of the auxiliary correction structure, so that the correction function of the entire structure can be stably realized, thereby ensuring that the overall mixing and piling effect of the structure is better.

[0034] Working principle: During the construction process, when any one of the three drill rods 2 is deflected, the drill rod 2 will push the first sliding ring 10 to slide. During the sliding process of the first sliding ring 10, the connecting ring body 11 will be driven to slide. During the sliding process of the connecting ring body 11, it will gradually offset the first sliding ring 10. In this process, the alarm 5 and the alarm light 6 are gradually powered, causing the alarm 5 to sound and the alarm light 6 to flash as a reminder, so that the operator can promptly discover that the drill rod 2 has deflected during operation. The operator starts the switch of the telescopic drive member 27, causing the telescopic drive member 27 to drive the drive plate 28 to slide downward.
