Description

Technical Field

[0001] This utility model relates to a construction machinery, and more particularly to a pile driving frame capable of multi-directional inclined pile driving construction that can perform forward and backward pitching and left and right tilting. Background Technology

[0002] Pile foundations are a key component of civil engineering construction. Their main function is to transfer building loads to deep soil layers or compact soft soil layers to improve bearing capacity. They are characterized by high bearing capacity, uniform settlement, ability to withstand various mechanical forces, and high construction efficiency, and are widely used in high-rise buildings, transportation subgrades, ports, bridges, marine engineering, etc.

[0003] Pile foundations include both vertical piles and inclined piles, with inclined piles further comprising piles with different inclination directions and angles. Inclined piles can transfer horizontal loads to the surrounding soil in the form of axial loads, reducing shear and bending moments in the pile body, thereby improving horizontal bearing capacity. Currently, inclined pile driving equipment can only tilt the pile frame backward for pile driving. This allows the pile and hammer to slide on the pile frame in a backward-tilting position, with the hammer driving the pile into the ground along the tilted frame. When the pile's tilt angle needs to be changed, such as driving the pile forward, to the left, or to the right, the entire pile driving equipment, including the crane, pile frame, and hammer, must be moved to the front of the pile. This ensures the pile, hammer, and frame remain in a backward-tilting position for the driving operation. This method requires constant adjustments to the crane and pile frame position according to the pile's tilt angle, resulting in higher manpower and equipment costs, longer construction periods, and significantly reduced efficiency. Especially when driving piles at multiple tilt angles alternately, the equipment must frequently relocate, greatly increasing workload and reducing efficiency, making this a critical technical problem that urgently needs to be solved in inclined pile construction. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide an all-round inclined pile driving frame that can realize vertical and multi-directional inclined pile driving operations without moving the pile driving equipment.

[0005] To solve the above-mentioned technical problems, the present invention provides an all-around inclined pile driving frame, including a lifting boom, on which a pile frame is hinged via a universal joint. A pile frame hydraulic cylinder is installed on the pile frame, and a pile frame sliding plate is also slidably supported on the pile frame. The pile frame sliding plate is connected to the pile frame hydraulic cylinder, and a universal telescopic rod is hinged to the pile frame sliding plate. The universal joint includes a pile frame hinge support and a boom hinge support. The pile frame hinge support is installed on the pile frame, and the boom hinge support is hinged to the lifting boom. The pile frame hinge support is connected to the boom hinge support via a universal joint. The universal telescopic rod includes a telescopic sleeve and a telescopic sliding rod that are slidably sleeved together. The telescopic sleeve is hinged to the sleeve hinge support, and the extended end of the telescopic sliding rod is hinged to the pile frame sliding plate.

[0006] In the above structure, the pile frame is hinged to the crane boom via a universal joint, giving it three degrees of freedom. This allows the pile frame to swing in three directions around the hinge point. When the pile frame is vertical, the pile hammer on it can drive vertical piles. When the pile frame is tilted forward, backward, left, or right, the pile hammer can drive piles in the tilted, up, and left / right directions respectively. The pile frame does not need to be moved; instead, it achieves omnidirectional pile driving by changing the posture of the pile frame on the crane boom. Furthermore, the pile frame is hinged to a universal telescopic rod via a sliding plate. This rod can extend, retract, lift, and swing downward, as well as swing to the right and left. This allows the pile frame to swing in multiple directions around the universal joint of the crane boom and the pile frame, guiding the pile hammer and piles to drive in vertical and multiple tilted directions. Furthermore, the pile frame is supported by a sliding plate, which is connected to the hydraulic cylinder and universal joint. The universal joint supports the pile frame to swing around the hinge point in multiple directions via the sliding plate. In particular, when the pile frame and the crane boom are at a dead point position parallel to each other, the universal joint cannot drive the pile frame to generate a swinging torque. At this time, the hydraulic cylinder of the pile frame generates a swinging torque on the pile frame, which in turn causes the pile frame to swing around the dead point.

[0007] In a further embodiment of this utility model, a boom hinge support shaft is installed on the boom hinge support, and the lifting boom is hinged to the boom hinge support shaft. The two rotation center lines of the universal joint and the axis of the boom hinge support shaft spatially intersect each other. This gives the pile frame three degrees of freedom, enabling multi-axis swinging of the pile frame.

[0008] In a further embodiment of this utility model, the universal joint includes a T-shaped pin. The horizontal pin of the T-shaped pin is rotatably mounted on the boom hinge support via a movable pressure plate, and the vertical pin of the T-shaped pin is hinged to the pile frame support via the hinge support. This ensures reliable swinging of the pile frame and facilitates maintenance and installation.

[0009] In a further embodiment of this invention, the universal joint includes a hinged ball head and a ball seat that are movably connected to each other, and the universal joint is located between the pile frame hinge support and the boom hinge support. This structure can bear pile frame loads in different directions and has a strong load-bearing capacity.

[0010] In a further embodiment of this utility model, a telescopic hydraulic cylinder is supported between the telescopic sleeve and the telescopic slide rod. The extended end of the telescopic slide rod is hinged to a pile frame positioning hinge support, which is hinged to the pile frame sliding plate. A pile frame positioning hydraulic cylinder is installed between the pile frame positioning hinge support and the telescopic slide rod. A sleeve swing hydraulic cylinder is installed between the telescopic sleeve and the sleeve hinge support. The lifting boom is hinged to a lifting platform, and the telescopic sleeve of the universal telescopic rod is hinged to the lifting platform via the sleeve hinge support. The lifting platform is a wheeled crane or a crawler crane. This allows the pile frame to swing in multiple directions.

[0011] In a further embodiment of this utility model, a pile-supporting device is installed on the pile frame, and pile frame legs are installed at the bottom end of the pile frame. The pile-supporting device includes two symmetrically arranged pile-supporting claw arms hinged to the pile frame. Each pile-supporting claw arm is hinged with a pile-supporting hydraulic cylinder. The claw end of the pile-supporting claw arm is provided with a pile-supporting roller and a pile-supporting claw finger. This enables the pile body to be reliably positioned and stabilized at the pile driving position.

[0012] In a further embodiment of this utility model, the pile frame sliding plate includes a sliding plate body with a sliding plate groove. The pile frame sliding plate is slidably supported on the slide rail of the pile frame through the sliding plate groove. The cylinder body of the pile frame hydraulic cylinder is mounted on the pile frame, and the piston rod end of the pile frame hydraulic cylinder is hinged to the pile frame sliding plate. The sliding structure is simple and compact, facilitating the driving of the pile frame. Attached Figure Description

Detailed Implementation

[0034] like Figure 1 , Figure 2 The omnidirectional inclined pile driving frame shown includes a lifting boom 4, which is hinged to a lifting platform 5. The lifting platform 5 is a crawler crane, but it can also be a wheeled crane, a walking mobile platform, or a ship's deck. The upper end of the lifting boom 4 is connected to a pile frame 1 via a universal hinge 3. Slide rails are provided on both the front and rear sides of the pile frame 1. The pile hammer 2 can be slidably supported on the pile frame 1 along the pile body via the corresponding side slide rail. A pile frame hydraulic cylinder 10 is installed on the other side of the pile frame 1.

A universal telescopic rod 6 is also hinged to the pile frame sliding plate 9, and the other end of the universal telescopic rod 6 is hinged to the lifting platform 5. A pile support device 8 is also installed on the pile frame 1. At the lower end of the pile frame 1, there is a pile frame support leg 7, which is a hydraulic cylinder.

[0035] The steel cable used to lift the pile hammer 2 passes sequentially around the pulley at the top of the pile frame 1 and the pulley on the lifting boom 4, and is wound onto the winch on the lifting platform 5. The pile hammer 2 can be a guide rod type diesel hammer, a cylindrical diesel hammer, or a hydraulic hammer, a vibratory hammer, etc.

A movable locking plate 305 is inserted into the sliding groove of the horizontal pin, and the movable locking plate 305 is fixedly installed on the bottom plate of the boom hinge support 303. The two ends of the vertical pin of the universal joint 302 are rotatably mounted on the hinge support 306, which is fixedly installed on the pile frame hinge support 301. Of course, this structure can also be such that the horizontal pin of the universal joint 302 is rotatably connected to the pile frame hinge support 301; while the hinge support 306, which supports the vertical pin of the movable universal joint 302, is fixedly installed on the boom hinge support 303.

In short, the two rotation center lines of the universal joint 302 and the axis of the boom hinge support 304 intersect each other spatially, or the three intersect each other perpendicularly. Alternatively, the universal joint 302 and the boom hinge support 304 can be made into an integral structure, in which the axes of the three pins are located in a three-dimensional coordinate system.

Two sleeve swing hydraulic cylinders 602 are symmetrically arranged on both sides of the telescopic sleeve 604.

[0045] like Figure 18, Figure 19 As shown, the pile-supporting device 8 includes two opposing pile-supporting claw arms 801, which are symmetrically located on both sides of the pile frame 1. The inner ends of the pile-supporting claw arms 801 are hinged to corresponding pile-supporting hinge supports 803, which are fixedly installed on the pile frame 1.
