Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, and in particular to a large-scale pipe pile lifting device. Background Technology

[0002] A pipe pile is a slender, tubular component primarily used in civil engineering as a pile foundation. During construction, the pipe pile is driven into the soil using a pile driver. Its cross-sectional dimensions are typically much smaller than its length, and it connects to a pile cap at the top to form the pile foundation.

[0003] When driving pipe piles into the ground, lifting equipment is needed to lift them. Because the pipe piles are long, the lifted pipe piles are prone to swinging in the air, which makes it impossible for the lifted pipe piles to remain vertical and affects the verticality of the piles during driving.

The telescopic rod 108 is slidably connected to the rotating rod 106. A hydraulic lever is provided inside the rotating rod 106, and the hydraulic lever pushes the telescopic rod 108 to slide on the rotating rod 106. It also includes a base 102 and an adjustment assembly 200. The section assembly 200 is fixed on the base 102. The adjustment assembly 200 can adjust the position of the pipe pile during hoisting, ensuring the pipe pile remains vertical after hoisting. The adjustment assembly 200 includes a connecting rod 201, a support plate 202, a rope 203, a fixing ring 204, a fixing frame 205, and a drum 206. The support plate 202 is rotatably connected to the end of the connecting rod 201, and the connecting rod 201 is slidably connected to the base 102. The connecting rod 201 is adjusted on the base 102 according to the required length of the pipe pile to be hoisted. The extended length of the support plate 202 contacts the end of the pipe pile. During the hoisting process, the pipe pile gradually rotates to a vertical position. The support plate 202 prevents the pipe pile from sliding on the ground during hoisting. When the pipe pile rotates to a vertical position, the support plate 202 can rotate with the pipe pile and make the pipe pile stand upright on the support plate 202. The telescopic rod 108 extends to hoist the pipe pile. At this time, the pipe pile is no longer in contact with the support plate 202. The drum 206 is fixed to the base 102 by the fixing frame 205, and the rope 203 is wound around the drum 206. On the 06, the drum 206 is driven to rotate by a motor, which drives the drum 206 to rotate, thereby realizing the winding and unwinding of the rope 203; the fixing ring 204 is detachably fixed to the end of the rope 203. The fixing ring 204 consists of two semi-circular rings, and the pipe pile can pass through the middle of the fixing ring 204.

[0042] Preferably, a fixing plate 112 is fixed on the upper side of the base 102; the support rod 103 is rotatably connected to the fixing plate 112, and the support rod 103 is fixed to the base 102 through the fixing plate 112.

The rotating shaft of the rotating seat 104 passes through the fixed plate 112, and the gears 111 mesh with each other. The rotating motor 110 drives the rotating seat 104 to rotate through the gear 111, and the rotating rod 106 rotates with the rotating seat 104. After the pipe pile is lifted, it can be moved from one side of the equipment to the other side of the equipment.

[0045] Preferably, the end of the rope 203 is fixed with a connecting buckle, and the fixing ring 204 is threaded onto the connecting buckle. The fixing rings 204 are fixed together by bolts. The fixing rings 204 can be replaced with appropriate fixing rings 204 according to the diameter of the pipe pile to be hoisted.

[0046] Preferably, the rotating rod 106 is rotatably connected to the support frame 105, and the support frame 105 is fixed to the rotating seat 104; the rotating seat 104 is fixed with a driver 109 for driving the rotating rod 106 to rotate, the driver 109 is located on one side of the support frame 105, and the driver 109 is used to drive the rotating rod 106 to rotate; the driver 109 is equipped with a motor and a gear 111 set inside, the motor drives the rotating rod 106 to rotate, the gear 111 set is composed of gear 111 and worm gear, the worm gear can lock the rotating rod 106 after power failure, thereby preventing the suspended pipe pile from falling.

The connecting rod 201 is slidably connected in the rectangular groove. Multiple through threaded holes are provided on the connecting rod 201. The length of the part of the connecting rod 201 extending out of the base 102 can be adjusted. When the pipe pile is lifted, the end of the pipe pile contacts the support plate 202. During the lifting process, the pipe pile will push the connecting rod 201 to slide towards the base 102. The length of the connecting rod 201 extending out is fixed by bolts.

[0050] Preferably, the fixing plate 112 is two rectangular plates with a gap between them, and the gear 111 is rotatably connected between the two fixing plates 112.

[0052] In actual use, a large pipe pile lifting device according to an embodiment of this application is as follows:

[0053] First, move the equipment close to the pipe pile so that the end of the pipe pile contacts the support plate 202. The pipe pile is then fixed by the clamp 107, and the fixing ring 204 is fitted onto the pipe pile. During hoisting, the pipe pile is gradually rotated to a vertical position, and the support plate 202 rotates with the pipe pile. During the rotation, the motor drives the drum 206 to rotate, causing the rope 203 to wind around the drum 206. This ensures that the rope 203 remains taut throughout the hoisting process, preventing the pipe pile from swaying. After the pipe pile reaches a vertical position, the telescopic rod 108 extends from the rotating rod 106, lifting the pipe pile upwards. The bottom of the pipe pile is no longer in contact with the support plate 202. The rotating motor 110 drives the rotating seat 104 to rotate, hoisting the pipe pile to the desired piling position.

[0054] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
