Description

Technical Field

[0001] This utility model relates to the technical field of pile drivers, and specifically to a miniaturized pile driver. Background Technology

[0002] In the field of foundation engineering construction, the construction of side piles, due to their proximity to buildings or pipelines, places higher demands on the equipment's ability to avoid space and the efficiency of the process. Traditional side pile construction pile machines are designed in a split manner, that is, the drilling equipment and the pile planting equipment operate separately. This split design leads to higher costs and requires alternating operations, resulting in low processing efficiency. Therefore, an integrated drilling and pile planting machine has emerged, which integrates drilling and pile planting into one design, which helps to improve construction efficiency.

[0003] Existing integrated piling rigs typically include a chassis, main mast, drilling assembly, and pile planting assembly. The bottom of the main mast connects to the top of the chassis. The drilling assembly includes a power head, drill rod, and guide cylinder. The pile planting assembly includes a pile clamping box, which is generally hinged to one side and its top is positioned above the chassis. The drill rod is vertically mounted on the main mast via the power head. The guide cylinder is vertically mounted directly below the power head and provides guidance and protection for the drill rod. As the drill rod descends, it moves the guide cylinder to one side of the bottom of the main mast. At this point, the pile clamping box needs to translate or rotate to achieve drilling. And the guide tube needs to be avoided. However, since the diameter of the guide tube is generally much larger than the diameter of the drill rod, the rotation space of the pile clamping box needs to be large enough to allow the guide tube to be avoided. Generally, only large pile drivers have enough space to avoid the guide tube. However, for some construction sites with small areas, large pile drivers cannot meet the construction needs. On small pile drivers, the guide tube is prone to interference with the pile clamping box, which affects the construction. In addition, if the pile is blocked and cannot be continued during the pile planting process, additional equipment needs to be mobilized to apply pressure so that it can continue to move down. The overall construction efficiency is low and the cost is high. Utility Model Content

[0004] This utility model addresses the aforementioned problems and aims to provide a miniaturized pile driver. By setting the first and second pile clamping boxes flush with or below the chassis, interference with the first guide cylinder can be effectively avoided. At the same time, the pressure cylinder between the first and second pile clamping boxes can apply pressure to the second pile clamping box, facilitating its breakthrough of obstacles for pile planting.

[0005] To achieve the above objectives, this utility model provides a miniaturized pile driver that can be used for side pile driving construction, comprising:

[0006] Chassis;

[0007] A mast assembly, comprising a main mast rotatably mounted on the chassis;

[0008] The first drilling assembly is mounted on the main mast in a liftable manner;

[0009] The first pile-planting assembly includes a first pile-clamping box and a second pile-clamping box for clamping piles. The first pile-clamping box is hinged to one side of the chassis, and the second pile-clamping box is mounted vertically and vertically below the second pile-clamping box via a drive component.

[0010] The first pile clamping box can drive the second pile clamping box to avoid the first drill rod assembly.

[0011] According to the miniaturized pile driver described above, the first drilling assembly includes a first power head, a first drill rod, and a first guide cylinder. Both the first power head and the first guide cylinder can be raised and lowered to connect with the main mast. The upper end of the first drill rod is connected to the first power head, and the lower end of the first drill rod can pass through the first guide cylinder and be located below the first guide cylinder.

[0012] According to the miniaturized pile driver described above, the top surface height of the first pile clamping box is lower than or equal to the top surface height of the chassis, so as to avoid the first guide cylinder.

[0013] According to the miniaturized pile driver described above, the mast assembly further includes a first slide rail arranged vertically on the main mast, the height of the first slide rail being the same as the height of the main mast, and the first power head and the first guide cylinder being arranged vertically on the first slide rail.

[0014] According to the miniaturized pile driver described above, the first pile planting assembly further includes a suspension component, and the mast assembly further includes a second slide rail arranged vertically on the main mast. The second slide rail and the first slide rail are arranged circumferentially on the main mast. The suspension component is vertically and elliptically mounted on the second slide rail and is used to provide a pile body for the first pile clamping box.

[0015] According to the miniaturized pile driver described above, the mast assembly further includes a winch, the top of the main mast is provided with a goose head, and each of the multiple outer overhanging ends of the goose head is provided with a fixed pulley. The first power head and the suspension member are both provided with movable pulleys. The winch is fixed to the chassis or the main mast, and the winch is provided with a rope. The rope is wound around the fixed pulley and then connected to the movable pulley.

[0016] According to the miniaturized pile driver described above, the first pile clamping box includes a first box body, a first clamping block and a first clamping cylinder. The first box body is hinged to the chassis by a rotating cylinder, and the first box body is provided with a hydraulic fixing pin, which can be inserted into the chassis. Two first clamping blocks are symmetrically arranged in the first box body. The first clamping cylinder is used to drive the two first clamping blocks to move toward the side closer to or away from each other.

[0017] The driving component is configured as a pressure cylinder, and two pressure cylinders are fixed on the symmetrical sides of the first housing, and the piston rods of the two pressure cylinders are respectively connected to the symmetrical sides of the second pile clamping box.

[0018] According to the miniaturized pile driver described above, the second pile clamping box includes a second box body, a second clamping block, a second clamping cylinder, and connecting parts. The two second clamping blocks are symmetrically arranged in the second box body. The second clamping cylinder is used to drive the two second clamping blocks to move toward or away from each other. The two connecting parts are symmetrically arranged on the top of the second box body and can be connected to the piston rod of the pressurizing cylinder.

[0019] The miniaturized pile driver described above also includes a second drilling assembly and a second pile planting assembly. An inner pile construction position is provided in the middle of the chassis. The second drilling assembly is movably mounted on the main mast and can rotate with the main mast to be directly above the inner pile construction position. The second pile planting assembly is movably mounted on the chassis and can be moved to be directly above or away from the inner pile construction position.

[0020] According to the miniaturized pile driver described above, the second pile planting component includes a static pressure pile planting mechanism and a crane. Guide rails are provided on both sides of the chassis of the inner pile construction station. The static pressure pile planting mechanism is movably mounted on the two guide rails. The crane is rotatably mounted on the chassis and is used to provide the pile body for the static pressure pile planting mechanism.

[0021] This utility model has the following beneficial effects:

[0022] 1. By setting the top surface of the first pile clamping box to be lower than or equal to the top surface of the chassis, the first guide tube can be avoided. At the same time, since the diameter of the first drill rod is smaller than that of the first guide tube, the first pile clamping box and the second pile clamping box can be rotated to avoid the first drill rod. This ensures that the drilling component and the pile planting component do not interfere with each other on the miniaturized pile machine, which can improve construction efficiency and is applicable to construction in limited sites.

[0023] 2. A pressure cylinder is installed between the first and second pile clamping boxes. The pressure cylinder can drive the second pile clamping box to move up and down relative to the first pile clamping box. When the second pile clamping box clamps the pile and the downward movement of the pile is hindered, the pressure cylinder can provide downward pressure to the second pile clamping box, thereby driving the pile to break through the obstruction and continue to move down. It has its own pressure effect to ensure construction efficiency.

[0024] 3. The use of hydraulic fixing pins can achieve rapid positioning of the first box, which in turn enables rapid positioning of the first and second pile clamping boxes, ensuring the stability of pile planting.

[0025] 4. It is also equipped with a second drilling assembly and a second pile planting assembly, which can be used for the construction of internal piles, thereby improving the functionality of the pile driver;

[0026] 5. During the downward drilling process, the first drill pipe can be guided by the first guide cylinder, which can effectively improve the stability of the first drill pipe and prevent it from deviating. Attached Figure Description

[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0037] like Figure 1-2 As shown, a miniaturized pile driver includes a chassis 100, a mast assembly 200, a first drilling assembly 300, a first pile planting assembly 400, a second drilling assembly 500, and a second pile planting assembly 600.

[0038] It can be used for side pile driving construction through the first drilling component 300 and the first pile planting component 400, and it can also be used for internal pile construction through the second drilling component 500 and the second pile planting component 600. Due to its miniaturization, it can be used for construction operations in relatively small spaces.

[0039] The chassis 100 is movable, and a walking mechanism is provided at the bottom of the chassis 100. This walking mechanism is used to drive the chassis 100 and multiple components located on the chassis 100 to move. In this embodiment, there are two types of walking mechanisms: one is a walking-track hybrid type, and the other is a fully walking type. The walking-track hybrid type is used for bridge and road construction, and the fully walking type is used for building construction. Different walking mechanisms can be selected according to different construction environments, and the walking mechanism can drive the chassis 100 to move to one side of the side pile construction position.

[0040] The mast assembly 200 includes a main mast 210 rotatably mounted on the chassis 100. In this embodiment, the main mast 210 is rotatably mounted on the left end of the chassis 100 to facilitate side pile construction. At the same time, a turntable is provided at the top of the left end of the chassis 100. The lower end of the main mast 210 is fixed on the turntable and can rotate with the turntable to adjust the position of other components located on the main mast 210.

[0041] The first drilling assembly 300 is vertically and flexibly mounted on the main mast 210 and can rotate with the main mast 210 to be directly above the side pile construction position. In this embodiment, the first drilling assembly 300 includes a first power head 310, a first drill rod 320, and a first guide cylinder 330. Both the first power head 310 and the first guide cylinder 330 can be vertically and flexibly connected to the main mast 210. The upper end of the first drill rod 320 is connected to the first power head 310, and the lower end of the first drill rod 320 can pass through the first guide cylinder 330 and is located below the first guide cylinder 330. The first guide cylinder 330 is located directly below the first power head 310 and is used to guide the first drill rod. 320 provides guidance. When the first drilling assembly 300 rotates with the main mast 210 to the side pile construction position, the first power head 310 descends, driving the first drill rod 320 and the first guide cylinder 330 to descend synchronously. During the descent, the first power head 310 can drive the first drill rod 320 to rotate for drilling. At the same time, when the first guide cylinder 330 descends with the first drill rod 320 to the top of the chassis 100, it can no longer descend. The first guide cylinder 330 remains in this position, which can ensure the stability of the drilling at the lower end of the first drill rod 320. After the drilling is completed, the first drill rod 320 can be driven to rise, driving the first guide cylinder 330 to rise, and then the pile planting operation can be carried out.

[0042] The first pile-planting assembly 400 includes a first pile-clamping box 410 and a second pile-clamping box 420 for clamping the pile. The first pile-clamping box 410 is hinged to one side of the chassis 100. The second pile-clamping box 420 is vertically and flexibly fixed below the second pile-clamping box 420 via a driving component. When the second pile-clamping box 420 clamps the pile and inserts it into the planting hole, it provides downward pressure through the driving component, which acts on the second pile-clamping box 420 and thus on the pile. This pressure helps the pile overcome obstacles and ensures proper planting. Furthermore, because the first pile-clamping box 410 is hinged to one side of the chassis 100, the second pile-clamping box 420... The second pile clamping box 420 is located below the first pile clamping box 410, at a lower overall position. The first pile clamping box 410 can drive the second pile clamping box 420 to rotate, thus avoiding the first drill rod assembly 300. In this embodiment, the top surface height of the first pile clamping box 410 is lower than or equal to the top surface height of the chassis 100 to avoid the first guide cylinder 330. Since the first guide cylinder 330 needs to descend with the first drill rod 320 for guidance during drilling, if the top surface height of the first pile clamping box 410 is higher than the top surface height of the chassis 100, it needs to rotate to avoid the first guide cylinder 330. To avoid interference with the first guide cylinder 330, the first guide cylinder 330 needs to be positioned higher than the first drill rod 320 due to its larger diameter. This requirement cannot be met in miniaturized pile drivers. Therefore, only by setting the top surface height of the first pile clamping box 410 to be lower than or equal to the top surface height of the chassis 100 can interference with the first guide cylinder 330 be prevented. Of course, the first drill rod 320 needs to drill into the ground below the chassis 100. The first pile clamping box 410 can drive the second pile clamping box 420 to rotate away from the edge pile construction position. Because the diameter of the first drill rod 320 is relatively small, the first clamping box... The limited rotation of the pile box 410 can also meet the need to avoid the first drill rod 320. Of course, after drilling is completed, the first pile clamping box 410 can drive the second pile clamping box 420 to rotate directly above the side pile construction position, and then carry out the pile planting action. Other components are used to lift the pile body onto the first pile clamping box 410. The first pile clamping box 410 clamps the pile body first, and then the pile body is lowered. Then the second pile clamping box 420 clamps the pile body, realizing sequential clamping and slowly inserting the pile body into the planting hole. This ensures that the first drilling component 300 and the first pile planting component 400 do not interfere with each other, which is suitable for small space processing.

[0043] Of course, in this embodiment, the first drill rod 320 not only has the function of drilling, but also the function of injecting mud. That is, while drilling, it can simultaneously coat the inner wall of the hole with mud such as cement to form a pile hole. Since this drill rod structure that can both drill and output mud is quite common, it will not be described again in this embodiment.

[0044] In this embodiment, edge pile construction can be carried out at a distance of two meters from the building or obstacle, which greatly improves applicability.

[0045] Specifically, the driving component is configured as a pressure cylinder 430. Two pressure cylinders 430 are fixed on the symmetrical sides of the first pile clamping box 410, and the piston rods of the two pressure cylinders 430 are respectively connected to the symmetrical sides of the second pile clamping box 420. That is, the two pressure cylinders 430 act synchronously to drive the sides of the second pile clamping box 420 to perform synchronous lifting and lowering movements. After the second pile clamping box 420 clamps the pile, its downward movement can provide downward pressure on the pile, which can make it break through the obstacle. The simultaneous pressure from both sides can ensure the centering of its implantation.

[0046] The first pile clamping box 410 includes a first box body 411, a first clamping block 414, and a first clamping cylinder 415. The first box body 411 provides support for the first clamping block 414 and the first clamping cylinder 415. The first box body 411 is hinged to the chassis 100 via a rotating cylinder 412, and a hydraulic fixing pin 413 is provided on the first box body 411. The hydraulic fixing pin 413 can be inserted into the chassis 100 to fix the first box body 411 directly above the side pile construction position. That is, the position of the first box body 411 can be adjusted by rotating the cylinder 412, thereby realizing the overall position adjustment of the first pile clamping box 410. The second pile clamping box 420 can be adjusted together with the first pile clamping box 410. When it is driven back to directly above the side pile construction position by rotating the cylinder 412, it can be quickly positioned by hydraulic fixing pin 413 to prevent it from shifting during construction and ensure construction accuracy.

[0047] Two first clamping blocks 414 are symmetrically arranged inside the first housing 411. The first clamping cylinder 415 is used to drive the two first clamping blocks 414 to move toward or away from each other. That is, the first clamping cylinder 415 can drive the two first clamping blocks 414 to move toward the side closer to each other to clamp the pile, and can drive the two first clamping blocks 414 to move away from each other to release the pile.

[0048] In this embodiment, the first clamping box 410 also includes an operating platform, which is fixed to the top of the first box body 411 for the operator to stand and perform various operations, including welding, disassembly and assembly. Of course, in order to prevent the operator from falling, a guardrail is provided on one side of the operating platform, and the operator can hold the guardrail to prevent himself from falling.

[0049] Specifically, the second clamping box 420 includes a second box body 421, a second clamping block 422, a second clamping cylinder 423, and a connecting member 424. The two second clamping blocks 422 are symmetrically arranged inside the second box body 421. The second clamping cylinder 423 is used to drive the two second clamping blocks 422 to move towards or away from each other. Similarly, the second clamping box 420 uses the second clamping cylinder 423 to drive the two second clamping blocks 422 to clamp and release the pile body. The two connecting members 424 are symmetrically arranged on the top of the second box body 421. The two connecting members 424 can be connected to the piston rod of the pressurizing cylinder 430 respectively to achieve connection with the pressurizing cylinder 430.

[0050] To ensure that the first power head 310 and the first guide cylinder 330 move in a vertical direction, the mast assembly 200 also includes a first slide rail 211 arranged vertically on the main mast 210. The height of the first slide rail 211 is the same as the height of the main mast 210, and the first power head 310 and the first guide cylinder 330 are arranged vertically on the first slide rail. That is, the first power head 310 can be raised to the top of the main mast 210 to ensure the length of the single first drill rod 320, and the first guide cylinder 330 can be lowered to the bottom side of the main mast 210 to provide better guidance for the first drill rod 320.

[0051] In this embodiment, in order to enable the first guide cylinder 330 to guide the first drill rod 320 and the first drill rod 320 to be displaced relative to the first guide cylinder 330, a transition fit is adopted between the first guide cylinder 330 and the first drill rod 320.

[0052] To provide pile bodies for the first pile clamping box 410 and the second pile clamping box 420, the first pile planting assembly 400 also includes a suspension member 440, and the mast assembly 200 also includes a second slide rail 212 arranged vertically on the main mast 210. The suspension member 440 is vertically detachable on the second slide rail 212 and is used to provide pile bodies for the first pile clamping box 410, that is, the pile body is hoisted using the suspension member 440, and it can rotate with the main mast 210 to be directly above the side pile construction position. The descent causes the pile to fall into the first pile clamping box 410. To avoid interference between the suspension component 440 and the first drilling assembly 300, the second slide rail 212 and the first slide rail 211 are arranged at intervals along the circumference of the main mast 210. They are not located on the same side, so that when the first drilling assembly 300 is drilling, the suspension component 440 is away from the side pile construction position, and when the suspension component 440 is on the side pile construction position, the first drilling assembly 300 is away from the side pile construction position.

[0053] To achieve the lifting and lowering movement of the first power head 310 and the suspension member 440, the mast assembly 200 also includes a winch. The top of the main mast 210 is provided with a gooseneck 213, and multiple fixed pulleys 213a are provided on the multiple outer overhanging ends of the gooseneck 213. The outer overhanging ends refer to the protruding ends of the gooseneck 213 extending outwards from the top of the main mast 210. These multiple spaced-apart outer overhanging ends are used to fix the multiple fixed pulleys 213a, and to connect the first power head 310 and the suspension member 440. Each of the hanging components 440 is equipped with a movable pulley 340, and two of these movable pulleys 340 correspond to two fixed pulleys 213a. The winch is fixed to the chassis 100 or the main mast 210, and a rope is provided on the winch. The rope is wound around the fixed pulley 213a and then connected to the corresponding movable pulley 340. The vertical drive is achieved through the cooperation of the fixed pulley 213a and the corresponding movable pulley 340, thereby driving the first power head 310 and the hanging component 440 to move up and down.

[0054] To increase the construction range, an inner pile construction position, i.e., a through hole connecting to the ground, is provided in the middle of the chassis 100. The second drilling assembly 500 is jacked up and down on the main mast 210 and can rotate with the main mast 210 to be directly above the inner pile construction position. It includes a second power head and a second drill rod. The second power head can drive the second drill rod and drill through the through hole to drill the ground. After completion, the second drilling assembly 500 can rotate with the main mast 210 to move away from the inner pile construction position. The second pile planting assembly 600 is movably mounted on the chassis 100. After drilling is completed, the second pile planting assembly 600 can be moved to be directly above the inner pile construction position to perform pile planting operation. Of course, during the drilling process and after the pile planting is completed, the second pile planting assembly 600 can also be moved away from the inner pile construction position.

[0055] Specifically, the second pile-planting assembly 600 includes a static pressure pile-planting mechanism 610 and a crane 620. Guide rails are provided on both sides of the chassis 100 of the inner pile construction position. The static pressure pile-planting mechanism 610 is movably mounted on the two guide rails, and the crane 620 is rotatably mounted on the chassis 100 and is used to provide the pile body for the static pressure pile-planting mechanism 610. That is, the crane 620 provides the pile body for the static pressure pile-planting mechanism 610, and the static pressure pile-planting mechanism 610 can implant the pile body into the hole. Since the static pressure pile-planting mechanism 610 and the crane 620 are conventional structures, they will not be described again in this embodiment.
