Description

Technical Field

[0001] This utility model relates to the field of pile driver technology, and in particular to an integrated static pressure pile driver. Background Technology

[0002] In pile driving construction, a drilling rig is first used to drill holes, and then a pile driver is used to drive the piles in. Because both of these machines are very heavy, weighing around 300 tons, they are extremely inconvenient to move during operation. This results in low work efficiency and seriously affects the construction schedule.

[0003] Therefore, an integrated static pressure pile driver has emerged, such as the integrated pile driver disclosed in patent publication number CN221721624U. This integrated pile driver combines the drilling mechanism of a drilling rig and the pile driving mechanism of a pile driver on the same chassis, allowing drilling and pile driving operations to be completed with a single device, thus improving work efficiency. However, because the column of its drilling mechanism is the same as that of existing drilling rigs, two inclined support rods are needed to support the column to ensure its stability during operation and to keep it vertical, preventing it from swaying. Since the lower part of the support rods needs to be far from the column to ensure stability, this structure results in a large chassis and volume for this integrated static pressure pile driver. It requires a lot of space during operation and movement, making the integrated static pressure pile driver cumbersome and inflexible during relocation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an integrated static pressure pile driver, which solves the problem that the current integrated static pressure pile drivers require a large chassis due to the need for struts to support the column, resulting in the inflexibility of the integrated static pressure pile driver when moving.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An integrated static pressure pile driver includes a chassis, a vertical main boom mounted on the chassis, and a power head mounted on the main boom that can move up and down along the main boom. Several drill rods are sequentially connected to the bottom of the power head. The main boom has a hollow vertical working space inside, and at least one vertical track is fixedly connected to the main boom within the working space. When drilling, the power head drives the drill rods and moves up and down along the track within the working space.

[0007] Furthermore, the track consists of two rails arranged within the workspace, and the power head is positioned between the two rails. The power head has a slider fixedly installed on one side corresponding to each rail, which is slidably connected to the rail.

[0008] Furthermore, a traveling frame is provided between the two tracks, the power head is located below the traveling frame, the traveling frame is connected to the top of the power head, and a movable pulley is rotatably connected to the top of the traveling frame.

[0009] Furthermore, a stationary pulley is provided at the top of the main boom, and a motor-driven winch is provided on one side of the chassis of the main boom. The wire rope of the winch passes through the pulley group composed of the stationary pulley and the moving pulley and is fixedly connected to the top of the main boom.

[0010] Furthermore, the main arm has an opening on one side of its lower part, and the main arm is provided with an openable door at the opening.

[0011] Furthermore, the chassis is also equipped with a crane, and the opening is located on the side of the main boom corresponding to the crane.

[0012] Furthermore, the main arm adopts a rectangular truss structure.

[0013] The positive effects of this utility model are:

[0014] This invention features a chassis with a truss-structured main boom mounted on it. Two vertical tracks run through the hollow working space within the main boom. A power head, capable of moving up and down along the tracks, is located within the working space. The increased cross-sectional area of ​​the truss-structured main boom reduces weight while maintaining sufficient rigidity. This main boom structure eliminates the need for support struts, ensuring the main boom remains vertical and stable during operation. The main boom is directly fixed to the chassis, further enhancing its stability. The elimination of inclined support struts on the sides of the main boom reduces the chassis area, improving flexibility, facilitating rapid movement and relocation, and increasing work efficiency. Because the power head is located between the two tracks, it moves up and down along the tracks via two sliders. This ensures that the power head receives a symmetrical torque on the two tracks, opposite to the torque applied during drill pipe rotation, preventing the power head from swinging within the working space or colliding with the main boom and causing accidents.

[0022] Figure 5 A conventional integrated static pressure pile driver is disclosed, comprising a chassis 12. From left to right, a turntable 2, a pile driving unit 9, and a crane 10 are arranged on the chassis 12. A traveling unit 11 is located at the bottom of the chassis 12. A vertical main boom 4 is mounted on the turntable 2. A vertical slide rail 6 is located on the right side of the main boom 4, and a power head 7, which can slide up and down along the slide rail 6, is located on the right side of the slide rail 6. The power output end of the lower part of the power head 7 is connected to a drill rod 8. A support rod 3 is located on the left side of the main boom 4. The upper end of the support rod 3 is connected to the upper part of the main boom 4, and the lower end of the support rod 3 is connected to the turntable 2 near the left end. A header 5 is located at the top of the main boom 4. A winch 2 is mounted on the turntable 2. The wire rope of the winch 2 passes upwards over a static pulley 14 on the header and connects to the top of the power head 7.

[0023] Example 1

[0024] like Figure 1 , Figure 2 As shown, an integrated static pressure pile driver has been further improved based on the existing integrated static pressure pile driver. The integrated static pressure pile driver eliminates the turntable 2, and the main boom 2 is fixedly connected to the chassis 12 near the middle. Simultaneously, the strut 3 and the forehead 5 are also eliminated. The main boom 4 adopts a rectangular truss structure, which is the same as the truss structure used in the main boom of tower cranes commonly used in building construction. There are two static pulleys 14, which are directly installed on the top of the main boom 4.

[0025] Because the main boom 4 adopts a truss structure and its cross-sectional area is increased, its weight is reduced while ensuring sufficient rigidity. This main boom 4 structure can maintain its verticality and stability during operation without the need for support rods 3. Since the support rods 3 are no longer required, the area of ​​the chassis 12 can be reduced, thereby improving the flexibility of this invention, facilitating rapid movement and relocation, and increasing work efficiency.

[0026] The main boom 4 has a hollow vertical working space, and a vertical track 15 is fixedly connected to each of the two opposite sides of the main boom 4 within the working space. The power head 7 is located within the working space and between the two tracks 15, and can move up and down along the two tracks 15.

[0027] The winch 2 is mounted on the chassis 12 and located to the left of the main boom 4. The winch 2 is motor-driven, and its wire rope winds upwards past the stationary pulley 14 before being secured to the top of the power head 7. During operation, the integrated static pile driver uses the power head 7 to rotate the drill rod 8. Simultaneously, the winch 2 can move the power head 7 up and down along the track 15 within the working space to perform drilling operations.

[0028] Example 2

[0029] Combination Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that:

[0030] The tracks 15 are two symmetrically arranged within the working space of the main arm 4, and the two tracks 15 are fixedly connected to opposite sides of the main arm 4. The power head 7 is located between the two tracks 15, and each power head 7 has a slotted slider 18 fixedly connected to one side corresponding to each track 15. The two sliders 18 are slidably connected to their respective tracks 15, and the slot openings on the two sliders 18 are opposite and both face outwards. Under the action of the sliders 18 and the tracks 15, the power head 7 can move up and down vertically along the tracks 15.

[0031] A traveling frame 16 is provided between the two tracks 15. The power head 7 is located below the traveling frame 16. The traveling frame 16 is connected to the top of the power head 7 by two pins. There are two movable pulleys 13 on the traveling frame 16. The free end of the wire rope of the winch 2 passes through the pulley group composed of two stationary pulleys 14 and two movable pulleys 13 in sequence and is fixedly connected to the top of the main boom 4.

[0032] The groove on the slider 18 is designed for sliding engagement with the track 15. When the power head 7 drives the drill rod 8 to rotate, it prevents the power head 7 from rotating due to torque, thus ensuring that the power head 7 smoothly transmits torque to the drill rod 8 and drives the drill rod 8 to rotate. Therefore, through the cooperation of the slider 18 and the track 15, and the action of the winch 2, while realizing the rotation of the drill rod 8, it can also drive the drill rod 8 to move vertically, realizing the vertical downward feed of the drill rod 8, or driving the power head 7 to move upward.

[0033] Since the power head 7 is located between the two tracks 15, the power head 7 moves on the tracks 15 through the two sliders 18, so that the power head 7 is subjected to a torque symmetrically applied to the two tracks 15 in the opposite direction to the rotation of the drill rod 8 when it is working, thereby preventing the power head 7 from swinging in the working space inside the main boom 4 or even colliding with the main boom 4.

[0034] Example 3

[0035] Combination Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that:

[0036] The lower part of the main arm 4 is on the rear side of the main arm 4 ( Figure 1 The main boom 4 has an opening (in the middle), the height of which is the same as the length of one section of drill pipe 8. An openable door 17 is provided at the opening. Figure 3 In the design, the right side of door leaf 17 is hinged to the main arm 4 via a door hinge, and the left side of door leaf 17 is connected to the main arm 4 via a latch. Alternatively, the left side of door leaf 17 can also be connected to the main arm 4 via an electromagnetic lock, thus locking door leaf 17 within the opening of the main arm without the need for climbing.

[0037] After the power head 7 moves a drill rod 8 to the bottom of the main boom 4, it locks the drill rod 8 in place. Then, the power head 7 separates from the drill rod 8, and the power head 8 moves upward. The door 17 is opened, and the crane 10 vertically lifts another drill rod 8, allowing its upper end to enter the working space inside the main boom 4 through the opening. This drill rod 8 connects to the power output end at the bottom of the power head 7. The power head 7 then moves upward, tightening the working space around the drill rod 8, thus allowing it to be delivered into the working space inside the main boom 4 through the opening. The bottom end of this drill rod 8 connects to the top end of the previous drill rod 8. The previous drill rod 8 is then released, the door 17 is closed, and drilling operations can continue.

[0038] After drilling is completed, the traveling unit 11 moves the chassis 12 to align the pile driving unit 9 with the drilled hole for pile driving. The specific structure and working principle of the traveling unit 11 and the pile driving unit 9 are existing technologies and will not be described in detail here.
