Technical Field

[0001] The present application relates to the technical field of foundation construction, and in particular to a CFG pile construction device. Background Art

[0002] CFG piles are cement fly ash gravel piles, which are used as foundations to compact soil and reduce foundation settlement and deformation in construction. In the construction process of CFG piles, the pile head needs to be cut after the pile is cast, and then the pile cap is cast. In this process, the construction device for cutting the pile head usually includes a trolley and a cutting disc, in which the cutting disc is installed on the trolley in a rotating connection.

[0003] In actual operation, the operator will push the cart and use the rotating cutting disc to cut the pile head. However, due to the mobility of the cart, when the cutting disc cuts into the outer wall of the pile head, the resistance generated between the cutting disc and the pile head may cause the cart to move along a path that deviates from the cutting direction. This deviation not only affects the smoothness and effect of cutting, but also may pose certain safety hazards to the operator. Summary of the invention

DETAILED DESCRIPTION

[0043] The following combination Figures 1 to 8 This application is described in further detail.

[0044] The present application embodiment discloses a CFG pile construction device. Figure 1 The CFG pile construction device includes a walking cart, a guide mechanism 4, a clamping mechanism 5 and a cutting mechanism 6. The guide mechanism 4 is connected between the walking cart and the clamping mechanism 5 to guide the relative movement of the walking cart and the clamping mechanism 5. The clamping mechanism 5 is used to clamp the pile head when cutting the pile head to improve the cutting stability and position accuracy. The cutting mechanism 6 is installed on the walking cart and is used to cut the pile head.

[0045] Reference Figure 1 and Figure 2 Specifically, the walking cart includes a first moving frame 1, a second moving frame 2 and a telescopic member 3. The bottom surfaces of the first moving frame 1 and the second moving frame 2 are flush and both are equipped with walking wheels 7, and the walking wheels 7 are universal wheels. The telescopic member 3 is installed between the first moving frame 1 and the second moving frame 2. The telescopic member 3 is an electric telescopic rod. The base of the telescopic member 3 is fixedly installed on the second moving frame 2. The telescopic end of the telescopic member 3 is connected to the first moving frame 1, so that the telescopic movement of the telescopic member 3 can drive the first moving frame 1 and the second moving frame 2 to move closer to or away from each other. In order to improve the stability of the distance adjustment between the first moving frame 1 and the second moving frame 2, a stabilizing sleeve 17 is fixed on the first moving frame 1, and a stabilizing rod 18 is provided on the second moving frame 2, which slides in the stabilizing sleeve 17 along the telescopic direction parallel to the telescopic member 3. When the telescopic member 3 is telescoped, the stabilizing rod 18 slides in the stabilizing sleeve 17.

[0046] Reference Figure 1 and Figure 2The guide mechanism 4 includes a base 41 and a guide rod 42. The base 41 is hollow cylindrical and connected to the first mobile frame 1, and the axis of the base 41 is parallel to the telescopic direction of the telescopic member 3. The guide rod 42 is round and coaxially slides in the base 41, and the guide rod 42 is connected to the clamping mechanism 5.

[0047] Reference Figure 1 and Figure 2 The clamping mechanism 5 includes a first connecting arm 51, a first clamping seat 52, a second connecting arm 53 and a second clamping seat 54. The first connecting arm 51 includes a connecting rod 511 and an adjusting rod 512 which are perpendicular and connected to each other, the first clamping seat 52 is connected to an end of the connecting rod 511 away from the adjusting rod 512, and an end of the guide rod 42 away from the base 41 is fixed to the connecting rod 511, and the connecting rod 511 extends in a horizontal direction and the extending length direction of the connecting rod 511 is perpendicular to the axial direction of the base 41.

[0048] The second connecting arm 53 is in the shape of a rod, and one end of the second connecting arm 53 is slidably sleeved on the outer wall of the adjusting rod 512 along the length direction of the adjusting rod 512. The second clamping seat 54 is connected to the end of the second connecting arm 53 away from the adjusting rod 512, and the length direction of the second connecting arm 53 is parallel to the length direction of the connecting rod 511. The first clamping seat 52 and the second clamping seat 54 are both in the shape of an arc, and the arc openings of the first clamping seat 52 and the second clamping seat 54 are opposite. In this embodiment, the first clamping seat 52 and the connecting rod 511 and the second clamping seat 54 and the second connecting arm 53 are all fixedly connected. In other embodiments, they can also be detachably connected by bolts. Among them, the second connecting arm 53 is used to sleeve the inner wall of the adjusting rod 512 and has a limiting protrusion (not shown in the figure), and the outer wall of the adjusting rod 512 has an adjusting groove (not shown in the figure) for the limiting protrusion to slide along the length direction of the adjusting rod 512. When the second connecting arm 53 slides on the adjusting rod 512, the limiting protrusion slides in the limiting groove to limit the rotation of the second connecting arm 53 relative to the adjusting rod 512. In addition, the adjusting rod 512 has an external thread, and the outer wall of the adjusting rod 512 is threadedly connected with a nut 19 that abuts against the second connecting arm 53, and the nut 19 is located on the side of the second connecting arm 53 away from the first connecting arm 51.

[0049] Reference Figure 1 and Figure 2The cutting mechanism 6 includes a rotating shaft 61 and a cutting disc 62. The rotating shaft 61 is rotatably connected to the first mobile frame 1 and is located at the end of the first mobile frame 1 away from the second mobile frame 2, and the axis of the rotating shaft 61 extends vertically, and the end of the base 41 away from the second mobile frame 2 extends beyond the side of the rotating shaft 61 away from the second mobile frame 2. The cutting disc 62 is fixed to the bottom end of the rotating shaft 61. In order to drive the rotating shaft 61 to rotate, a driving motor 20 is installed on the first mobile frame 1, and the axis of the output end of the driving motor 20 is parallel to the axis of the rotating shaft 61. The output end of the driving motor 20 and the rotating shaft 61 are linked by the cooperation of a pulley and a belt, so that when the output end of the driving motor 20 rotates, the rotating shaft 61 is driven to rotate together.

[0050] When in use, firstly, the first clamping seat 52 and the second clamping seat 54 are used to clamp the pile head together, so that the guide rod 42 extends radially along the pile head and the nut 19 is threadedly moved to abut against the second connecting arm 53, so that the first clamping seat 52 and the second clamping seat 54 keep the state of clamping the pile head. Then the walking cart is pushed until the cutting disc 62 abuts against the outer wall of the pile head, and the telescopic end of the telescopic member 3 is in a retracted state. Then the telescopic end of the telescopic member 3 is extended, and the driving motor 20 drives the cutting disc 62 to rotate at the same time, so that the cutting disc 62 extends to cut the pile head. After the telescopic end of the telescopic member 3 is fully extended, the operator pushes the walking cart to continue to move forward, so as to drive the cutting disc 62 to continue cutting forward under the guidance of the base 41 and the guide rod 42, until the base 41 abuts against the connecting rod 511. When stopping cutting, the driving motor 20 stops driving the cutting disc 62 to rotate, and the telescopic end of the telescopic member 3 is recovered at the same time, so as to drive the cutting disc 62 to retreat. In addition, after the cutting disc 62 cuts into the pile head in a straight line direction, the nut 19 on the adjusting rod 512 can be loosened to reduce the friction between the first clamping seat 52 and the second clamping seat 54 and the outer wall of the pile head, and then the walking cart can be pushed to move along the circumference of the pile head, so that the cutting disc 62 can cut the pile head along the circumference of the pile head under the guidance of the first clamping seat 52 and the second clamping seat 54.

[0051] Reference Figure 1 and Figure 2 Furthermore, since friction heat is generated during the cutting process of the cutting disc 62, in order to cool the cutting disc 62 and increase lubrication, a cooling mechanism 8 for spraying water to cool the cutting disc 62 is installed on the second mobile frame 2. Specifically, the cooling mechanism 8 includes a water tank 81 and a water pipe 82. The water tank 81 is fixedly installed on the second mobile frame 2, and the water tank 81 is located above the base 41. The water pipe 82 is connected and communicated with the bottom end of the water tank 81 and extends vertically, and the bottom end of the water pipe 82 is opposite to the upper surface of the cutting disc 62.

[0052] Reference Figure 1 and Figure 3, wherein the water delivery pipe 82 includes a first pipe 821, a transition pipe 822 and a second pipe 823 which are fixedly connected in sequence from top to bottom. The first pipe 821 and the second pipe 823 are both pipes made of hard materials, and the first pipe 821 is fixed and connected to the bottom end of the water tank 81. The transition pipe 822 is a pipe made of rubber and can undergo elastic deformation, and the bottom end of the second pipe 823 is close to and opposite to the upper surface of the cutting disc 62.

[0053] The flow and stop of water flow in the water delivery pipe 82 depends on the deformation of the transition pipe 822. Specifically, the first pipe 821 is connected with a limit seat 9 extending downward to the side opposite to the transition pipe 822, and the limit seat 9 is connected to the side of the transition pipe 822 away from the first connecting arm 51. The first mobile frame 1 is fixedly connected with an opening and closing seat 10 extending to the side opposite to the transition pipe 822, and the opening and closing seat 10 is connected to the side of the transition pipe 822 close to the first connecting arm 51, and the opening and closing seat 10 and the limit seat 9 are located on the same horizontal plane, and the width of the opening and closing seat 10 and the limit seat 9 connected to the transition pipe 822 is greater than the width of the transition pipe 822.

[0054] When the telescopic end of the telescopic member 3 is retracted, the opening and closing seat 10 is driven to move toward the direction close to the limiting seat 9, so that the opening and closing seat 10 and the limiting seat 9 jointly flatten and clamp the transition tube 822, so that the transition tube 822 fits against the two inner walls, so that the transition tube 822 is in a closed state, and the opening and closing seat 10 and the limiting seat 9 jointly cut off the communication path between the first tube 821 and the second tube 823. When the telescopic end of the telescopic member 3 is extended, the opening and closing seat 10 is driven to move away from the limiting seat 9, and the transition tube 822 is out of the fitting state relative to the two inner walls, so that the transition tube 822 is in an open state, and the first tube 821 and the second tube 823 are connected through the transition tube 822.

[0055] The water in the water tank 81 is naturally flowed downward into the transition pipe 822 under the influence of gravity. By moving the opening and closing seat 10, the transition pipe 822 is automatically opened during cutting to allow the water to flow downward to the cutting disc 62 through the second pipe 823. When cutting is stopped, the transition pipe 822 is automatically closed to stop the water from flowing to the cutting disc 62.

[0056] Reference Figure 1 and Figure 3Furthermore, in order to improve the effect of watering the cutting disc 62, a swinging member 11 is connected between the first tube 821 and the second tube 823, and the swinging member 11 can drive the second tube 823 to swing back and forth relative to the first tube 821 to expand the watering range of the second tube 823. The swinging member 11 is a U-shaped structure with an opening toward the transition tube 822. The top end of the swinging member 11 is rotatably connected to the outer wall of the first tube 821, and the rotation axis of the swinging member 11 is parallel to the telescopic direction of the telescopic member 3. The bottom end of the swinging member 11 is fixed to the outer wall of the second tube 823, so that the second tube 823 is driven to swing by the rotation of the swinging member 11, and the transition tube 822 is elastically deformed when the second tube 823 swings.

[0057] Reference Figure 2 and Figure 3 In order to drive the swing member 11 to rotate, the base 41 rotates around its own axis on the first moving frame 1, and a guide member 12 is provided between the base 41 and the guide rod 42, and a linkage assembly 13 is provided between the base 41 and the first tube 821. When the base 41 is displaced in the axial direction relative to the guide rod 42, the guide member 12 causes the base 41 to reciprocate at the same time. When the base 41 reciprocates, the linkage assembly 13 drives the swing member 11 to reciprocate at the same time.

[0058] Reference Figure 1 , Figure 4 and Figure 5 Specifically, the guide member 12 is fixed on the outer peripheral wall of the guide rod 42 at one end away from the first connecting arm 51, and is in the shape of a convex column protruding from the outer peripheral wall of the guide rod 42. The inner wall of the base 41 is provided with a wavy guide groove 14 along its own axial direction, and the guide groove 14 is used for the guide member 12 to press into and slide. Specifically, the guide groove 14 includes a first groove 141 and a second groove 142 that are alternately distributed and connected. The first groove 141 extends obliquely along the circumference of the base 41, and the inclination direction of the first groove 141 is gradually inclined upward in the direction away from the first connecting arm 51. The second groove 142 also extends obliquely along the circumference of the base 41, and the inclination direction of the second groove 142 is gradually inclined downward in the direction away from the first connecting arm 51. The center angles through which the first groove 141 and the second groove 142 extend are consistent.

[0059] When the operator pushes the cutting disc 62 to cut the pile head so that the base 41 moves toward the first connecting arm 51 , the guide member 12 is driven to slide in the guide groove 14 . The guide member 12 passes through the first groove 141 and the second groove 142 alternately in sequence, thereby driving the base 41 to reciprocate.

[0060] Reference Figure 2 and Figure 3The linkage assembly 13 includes a main gear 131 and a slave gear 132. The main gear 131 is coaxially fixedly sleeved on the outer wall of the base 41, and the slave gear 132 is fixed on the swing member 11, and the axis of the slave gear 132 coincides with the rotation axis of the swing member 11. The main gear 131 is meshed with the slave gear 132, and the width of the main gear 131 is greater than the width of the slave gear 132, so that when the telescopic member 3 is extended and retracted to drive the main gear 131 and the slave gear 132 to have a relative displacement along the extension direction of the telescopic member 3, the main gear 131 and the slave gear 132 always maintain a meshing state.

[0061] Therefore, when the base 41 reciprocates, the engagement between the main gear 131 and the slave gear 132 drives the swing member 11 to reciprocate relative to the first tube 821 , thereby driving the second tube 823 to reciprocate and swing.

[0062] Reference Figure 6 Furthermore, in order to facilitate water addition to the water tank 81, a water addition hole 21 is provided on the top of the water tank 81, and the water tank 81 is equipped with a rubber plug 22 capable of plugging the water addition hole 21. When water needs to be added to the water tank 81, the rubber plug 22 is pulled out to add water from the water addition hole 21, and after the water addition is completed, the rubber plug 22 is plugged back into the water addition hole 21.

[0063] Reference Figure 6 and Figure 7 Furthermore, a connecting portion 15 and a closing portion 16 are alternately arranged in sequence along the circumference of the first tube 821 at the bottom of the water tank 81 opposite to the tube opening of the first tube 821. The connecting portion 15 is in the shape of a fan-shaped hole, and the inner cavity of the water tank 81 is connected to the first tube 821 through the connecting portion 15. The closing portion 16 is in the shape of a fan-shaped plate, and is located between two adjacent connecting portions 15. The water tank 81 also has a volume adjustment mechanism that is opposite to and cooperates with the connecting portion 15 and the closing portion 16. The volume adjustment mechanism adjusts the size of the connecting portion 15 connecting the water tank 81 and the first tube 821, thereby adjusting the water output of the water delivery pipe 82 according to the on-site conditions.

[0064] Reference Figure 6 , Figure 7 and Figure 8Specifically, the amount adjustment mechanism includes an adjusting disk 23, a connecting rod 24 and a rotating sleeve 25. The adjusting disk 23 is in the shape of a disk and is rotatably connected to the bottom of the water tank 81. The lower surface of the adjusting disk 23 is also in contact with the inner bottom wall of the water tank 81, and the adjusting disk 23 is coaxial with the first tube 821. Through holes 26 are evenly spaced along the upper edge of the adjusting disk 23. The through holes 26 correspond to the connecting portion 15 one by one, and the size of the through holes 26 is consistent with the size of the connecting portion 15. The connecting rod 24 is in the shape of a square rod, the bottom end of the connecting rod 24 is fixed at the center of the adjusting disk 23, and the connecting rod 24 extends vertically in the water tank 81. The rotating sleeve 25 is slidably sleeved on the top of the connecting rod 24, and the upper and lower threads of the rotating sleeve 25 are penetrated through the top of the water tank 81. In order to conveniently rotate the rotating sleeve 25, a hand wheel is provided on the top of the rotating sleeve 25.

[0065] By rotating the rotating sleeve 25, the rotating sleeve 25 can be driven to move on the water tank 81 along the vertical thread, and the rotating sleeve 25 slides up and down relative to the connecting rod 24, and the connecting rod 24 rotates together with the rotating sleeve 25, thereby driving the adjusting disk 23 to rotate. When the adjusting disk 23 rotates, the through hole 26 and the connecting portion 15 can be connected or misaligned, so that the size of the overlapping portion of the through hole 26 and the connecting portion 15 can be adjusted, and the overlapping portion of the through hole 26 and the connecting portion 15 is the portion where water flows through.

[0066] The implementation principle of a CFG pile construction device in an embodiment of the present application is as follows: first, the pile head is clamped by the first clamping seat 52 and the second clamping seat 54, and then the walking cart is pushed until the cutting disc 62 abuts against the outer wall of the pile head, and then the driving motor 20 is turned on to drive the cutting disc 62 to rotate, and then the telescopic end of the telescopic member 3 is extended to drive the cutting disc 62 to cut forward into the pile head. Then, the operator pushes the walking cart to continue moving forward to cut the pile head, and stops cutting when the base 41 abuts against the connecting rod 511, at which time the center of the cutting disc 62 is close to the outer wall of the pile head. After that, the cutting disc 62 can be pulled out and the direction can be changed to cut the pile head, or the walking cart can be moved along the circumference of the pile head while the cutting disc 62 remains on the pile head to continue cutting the pile head.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
