Description

Technical Field

[0001] The invention relates to a pile sinking device, in particular to a pile sinking device for high molecular polymer sheet piles and round piles, and belongs to the technical field of construction engineering. Background Art

[0002] Common high molecular polymers include polyethylene, polypropylene, polyvinyl chloride, etc. These polymers have good chemical stability, corrosion resistance and other characteristics. They will not rust as easily as steel sheet piles, can maintain structural integrity for a long time, reduce maintenance costs, and are light in weight, which makes them more convenient during transportation and construction. Piles made of high molecular polymers are gradually replacing traditional metal sheet piles and round piles, and during the use of sheet piles and round piles, pile sinking devices are required for insertion and installation.

[0003] In the prior art, for example, the invention with application number 202310505117.4 discloses a vibrating pile driver for bridge construction. In order to solve the problem that the vibration force of the vibrator is transmitted to the cantilever of the crane through the hoisting wire rope, or directly acts on the arm of the excavator, which not only increases the loss of its vibration energy, but also seriously affects the stability of the arm of the crane or excavator. It is very easy for the pile body to swing laterally due to the shaking of the arm of the crane or excavator, and then cause the sunken pile body to tilt, which buries a huge safety hazard for subsequent construction, and has poor stability and reliability. By setting the support rod on the vibrator housing and the linkage structure between it and the pile clamp, when the eccentric block is triggered, vibration can be generated along the central axis direction of the support rod, without causing vibration to the hanger and transmitting it to the arm of the crane or excavator, thereby effectively reducing the vibration energy loss of the high-vibration pile driver during operation. At the same time, it will not affect the stability of the arm of the crane or excavator, and will not cause the pile body to swing laterally and tilt and sink due to its shaking.

[0004] Similar to the above application, there are still some shortcomings:

[0005] During the pile driving operation, the applicability of the pile clamp is low and it can only stably clamp a single type of pile. In addition, during the process of lifting the pile, when the excavator cantilever drives the device to move, it is easy to cause the pile to swing greatly, requiring a certain amount of time to adjust the position, affecting the vertical insertion rate of the pile.

[0006] Therefore, a pile sinking device for polymer sheet piles and round piles is designed to optimize the above problems. Summary of the invention

[0007] The main object of the present invention is to provide a pile sinking device for polymer polymer sheet piles and round piles. A bidirectional hydraulic cylinder is horizontally installed in a fixed seat at the bottom of a vibrator, and mounting blocks are fixed to the output ends of the bidirectional hydraulic cylinder. In addition, chucks are rotatably installed at the bottom ends of the mounting blocks. During the use of the device, by controlling the distance between the two groups of chucks and the rotation angle of the chucks, it is convenient to stably clamp the sheet piles and round piles, with higher applicability. Symmetrically arranged cylindrical limit blocks are provided on both sides of the vibrator, and the cylindrical limit blocks can slide and rotate inside the strip-shaped limit grooves, which can not only avoid affecting the stability of the hoisting equipment during the vibration process, but also control the vibrator to lie flat on the ground during the clamping process of the pile body. In addition, with the heightening mechanism, the position of the chuck can be controlled according to the height of the pile body, so that the device can quickly clamp and install the pile body on the ground, with higher practicality. A vertical positioning mechanism composed of a vertical hydraulic cylinder, an arc-shaped support block, a first spring, a groove, a horizontal hydraulic cylinder, a connecting pipe, a slide rod, a chute, a ball and a conical socket is provided at both ends of the U-shaped hanging frame. During the process of lifting and swinging the pile body, when the end of the slide rod aligns with the conical socket, under the action of the gravity of the device itself, the slide rod is automatically inserted into the conical socket to ensure that the whole device and the pile body are in an integrated vertical state, improving the vertical pile sinking rate of the pile body.

[0044] To make the technical personnel in this technical field more clear and definite about the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the implementation manners of the present invention are not limited thereto.

[0045] As Figure 1-Figure 9 As shown in Figure 1-Figure 9 , this embodiment provides a pile sinking device for polymer polymer sheet piles and round piles, including a vibrator 1. A U-shaped hanging bracket 2 is arranged at the top of the vibrator 1. Cylindrical limit blocks 3 are symmetrically fixed on both sides of the vibrator 1. Strip-shaped limit grooves 4 are vertically opened on both sides of the U-shaped hanging bracket 2. The width of the strip-shaped limit grooves 4 is greater than the diameter of the cylindrical limit blocks 3. The cylindrical limit blocks 3 rotate and slide inside the strip-shaped limit grooves 4. Vertical positioning mechanisms 5 for limiting the vibrator 1 are arranged at the bottom ends of both sides of the U-shaped hanging bracket 2. A connecting rib plate 6 is fixed at the bottom end of the vibrator 1. A fixed seat 7 is fixed at the bottom end of the connecting rib plate 6. A bidirectional hydraulic cylinder 8 is horizontally installed at the middle position inside the fixed seat 7. Installation blocks 9 are installed on the output shafts at both ends of the bidirectional hydraulic cylinder 8. Second hydraulic rotary devices 11 are installed at the bottom ends of the installation blocks 9. Chucks 12 are installed at the bottom ends of the second hydraulic rotary devices 11. A heightening mechanism 10 is arranged on the end face of the fixed seat 7.

[0046] Total working principle: During installation, connect the top of the U-shaped hanging bracket 2 to the excavator boom. When clamping the sheet pile on the ground, move the device to the end of the sheet pile, then place the vibrator 1 flat on the ground, while the U-shaped hanging bracket 2 is perpendicular to the plane, and the chuck 12 at the bottom of the vibrator 1 is aligned with the end of the sheet pile. Use the bidirectional hydraulic cylinder 8 to control the distance between the chucks 12, and at the same time use the heightening mechanism 10 to adjust the position of the chuck 12 according to the height of the sheet pile. Then use the second hydraulic rotary device 11 to control the rotation of the chuck 12, align the two chucks 12 with the middle protrusion of the splint at the same time or control the two chucks 12 to be inclined to align with both sides of the splint respectively. After the angle adjustment of the chuck 12 is completed, the excavator boom applies a thrust to the vibrator 1 through the U-shaped hanging bracket 2, controls the vibrator 1 to move in the direction of the sheet pile, inserts the end face of the sheet pile into the clamping groove of the chuck 12, and uses the chuck 12 to fix the sheet pile. After the fixation of the sheet pile is completed, lift the excavator boom to lift the sheet pile upward. When clamping the round pile, also place the vibrator 1 flat on the ground, and the chuck 12 is aligned with the end of the round pile. Start the bidirectional hydraulic cylinder 8 to adjust the distance between the two chucks 12 according to the diameter of the round pile, and then use the heightening mechanism 10 to place the chuck 12 at the horizontal center line position of the round pile. Use the second hydraulic rotary device 11 to control the clamping groove of the chuck 12 to align with both sides of the round pile, and then push the chuck 12 in the direction of the round pile. The chuck 12 is stuck at the symmetrical side of the round pile to clamp and lift the round pile. During the process of lifting and moving the sheet pile or round pile, since the U-shaped hanging bracket 2 is movably connected to the vibrator 1, the pile body will swing. During the swinging process of the pile body, when it reaches the vertical state, at this time, the vertical positioning mechanism 5 can fix the position of the pile body to ensure that the whole device and the pile body are in an integral vertical state. After the pile body moves to the designated position, the excavator boom moves vertically downward, and then through the vibration of the vibrator 1, pile sinking operation is carried out.

[0047] In this embodiment, a first hydraulic rotator 201 is installed at the middle position of the top of the U-shaped hanger 2, and a connecting seat 202 is fixed to the top of the first hydraulic rotator 201, and the connecting seat 202 is connected to the excavator cantilever.

[0048] Partial working principle: During the installation of the device, the connecting seat 202 is connected to the end of the excavator boom, and during use, the hydraulic pipe on the excavator is connected to the first hydraulic rotator 201, which can be used to rotate and adjust the angle during the pile lifting process.

[0049] In this embodiment, the side edges of the fixed seat 7 are uniformly and vertically installed with limiting rods 901, and fixing plates 902 are fixed between the ends of the limiting rods 901 on both sides of the fixed seat 7. The mounting block 9 is slidably connected to the limiting rods 901, and a second spring 903 is provided between the mounting block 9 and the fixing plate 902.

[0050] Partial working principle: When the two-way hydraulic cylinder 8 controls the installation block 9 to move, the limiting function of the limiting rod 901 can ensure that the installation block 9 moves in a straight line, and the use of the second spring 903 can facilitate the rapid resetting of the installation block 9 during use.

[0051] In this embodiment, four groups of limiting rods 901 are provided, and the limiting rods 901 are respectively located at the corners of the fixing seat 7 , and the limiting rods 901 pass through the second springs 903 .

[0052] Partial working principle: The use of multiple groups of limiting rods 901 makes the mounting block 9 more stable, and the limiting rods 901 can limit the second spring 903, effectively preventing the second spring 903 from deforming to the side.

[0053] In this embodiment, the raising mechanism 10 includes a supporting hydraulic cylinder 1001 and a pad 1002. The supporting hydraulic cylinder 1001 is evenly installed inside the fixed seat 7, and the output end of the supporting hydraulic cylinder 1001 extends to the outer end of the fixed seat 7. The pad 1002 is fixed between the ends of multiple groups of supporting hydraulic cylinders 1001, and the pad 1002 is parallel to the end face of the fixed seat 7.

[0054] Local working principle: When clamping the pile on the ground, the pad 1002 is in contact with the ground, and the hydraulic oil pipe on the excavator is connected to the supporting hydraulic cylinder 1001, which can control the extension and retraction of the supporting hydraulic cylinder 1001, and then adjust the horizontal height of the vibrator 1 and the clamp 12.

[0055] In this embodiment, the vertical positioning mechanism 5 includes a conical socket 501, a vertical hydraulic cylinder 502, an arc-shaped support block 503, a first spring 504, a horizontal hydraulic cylinder 506, a connecting pipe 507, a sliding rod 508, a sliding groove 509 and a conical socket 501. The conical socket 501 is opened on both sides of the vibrator 1 and is directly below the cylindrical limiting block 3. The vertical hydraulic cylinder 502 is vertically installed at the bottom end of the U-shaped hanger 2, and the output ends of the vertical hydraulic cylinder 502 all extend into the strip-shaped limiting groove 4. Arc-shaped support blocks 503 are fixedly installed at the output ends of the vertical hydraulic cylinders 502. A first spring 504 is provided between the bottom of the arc-shaped support block 503 and the bottom of the strip-shaped limiting groove 4. Horizontal hydraulic cylinders 506 are vertically installed at the bottom of both sides of the U-shaped hanger 2. A connecting pipe 507 is provided between the end of the horizontal hydraulic cylinder 506 and the end of the vertical hydraulic cylinder 502. A sliding rod 508 is installed at the output end of the horizontal hydraulic cylinder 506. The sliding rod 508 slides inside the U-shaped hanger 2, and one end of the sliding rod 508 extends to the inside of the U-shaped hanger 2. A sliding groove 509 is opened along the length direction on the sliding rod 508. The output end of the vertical hydraulic cylinder 502 passes through the inside of the sliding groove 509. A ball 510 is rotatably installed at one end of the sliding rod 508 close to the vibrator 1, and the ball 510 is in contact with the surface of the vibrator 1.

[0056] Local working principle: During the process of lifting the pile body and the vibrator 1, the pile body drives the vibrator 1 to swing around the cylindrical limiting block 3. The total weight of the pile body and the vibrator 1 will be applied to the vertical hydraulic cylinder 502. The inside of the vertical hydraulic cylinder 502 is in communication with the inside of the horizontal hydraulic cylinder 506. Both the inside of the vertical hydraulic cylinder 502 and the inside of the horizontal hydraulic cylinder 506 are in a high-pressure state. The ball 510 on the sliding rod 508 fits against the side of the vibrator 1 and continuously rolls as the vibrator 1 swings. When the conical socket 501 on the vibrator 1 aligns with the end of the sliding rod 508, the hydraulic oil inside the vertical hydraulic cylinder 502 will quickly enter the inside of the horizontal hydraulic cylinder 506, and the sliding rod 508 will quickly insert into the conical socket 501 to limit the position of the vibrator 1, so as to ensure that the vibrator 1, the pile body and the U-shaped hanger 2 are in an integrated state and perpendicular to the horizontal plane, and then the pile driving process is carried out.

[0057] In this embodiment, a groove 505 is opened at the inner bottom of the strip-shaped limiting groove 4. The bottom end of the first spring 504 is located inside the groove 505, and the output end of the vertical hydraulic cylinder 502 passes through the first spring 504.

[0058] Local working principle: The setting of the groove 505 can hide the arc-shaped support block 503 and the first spring 504 after the sliding rod 508 is inserted into the conical socket 501, and the vertical hydraulic cylinder 502 will not be in a high-pressure state.

[0059] In this embodiment, the clamp 12 includes a clamp seat 1201, a fixed clamp block 1202, a sliding clamp block 1203 and a clamping hydraulic cylinder 1204. The clamp seat 1201 is vertically fixed at the bottom of the second hydraulic rotator 11. The fixed clamp block 1202 is fixed on one side of the bottom of the clamp seat 1201, and the sliding clamp block 1203 is slidably installed on the other side of the bottom of the clamp seat 1201. The inside of the clamp seat 1201 is installed with a clamping hydraulic cylinder 1204 for controlling the linear sliding of the sliding clamp block 1203.

[0060] Local working principle: In the process of clamping the pile body, the hydraulic pipeline of the excavator is connected to the clamping hydraulic cylinder 1204, the fixed clamp block 1202 and the sliding clamp block 1203 are respectively clamped on both sides of the pile body, and then the clamping hydraulic cylinder 1204 is used to control the sliding clamp block 1203 to move toward the fixed clamp block 1202, and the fixed clamp block 1202 and the sliding clamp block 1203 are then tightly fitted to the surface of the pile body for clamping and fixing.

[0061] In this embodiment, a mounting groove 1205 is vertically opened at the middle position of the inner side of the sliding clamp 1203, a third spring 1207 is evenly installed on the inner end surface of the mounting groove 1205, and a plate 1206 is installed at the end of the third spring 1207, and the sides of multiple sets of plates 1206 are fitted together.

[0062] Local working principle: In the initial state, the sticking plate 1206 protrudes from the side of the sliding clamp 1203. When the round pile is clamped and fixed, the sliding clamp 1203 is located on the outside of the round pile, and the outer wall of the round pile will squeeze the sticking plate 1206. The elastic force applied by the third spring 1207 is used to fit the sticking plate 1206 to the surface of the round pile, and the two ends of the inner side of the sliding clamp 1203 will also contact the round pile, thereby increasing the clamping stability of the round pile. When clamping the sheet pile, the sticking plate 1206 and the sliding clamp 1203 are all in contact with the sheet pile, with a larger contact area and higher clamping stability.

[0063] In this embodiment, both ends of the inner side of the sliding clamp block 1203 and the end surface of the sticking plate 1206 are provided with anti-slip grooves, and the anti-slip grooves are parallel to the horizontal plane.

[0064] Local working principle: The anti-slip pattern can effectively prevent the pile from sliding, ensuring stability during pile sinking.

[0065] The above description is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the scope disclosed by the present invention, which belong to the protection scope of the present invention.
