Description

Technical Field

[0001] This utility model belongs to the field of pipe pile hoisting technology, specifically relating to a steel pipe pile lowering guide hoisting device. Background Technology

[0002] Chinese patent application number 202221791788.9 discloses an automatic pipe pile lifting device. This device uses a limiting component to limit the insertion and connection of both ends of the pipe pile, providing a good limiting effect during lifting and preventing slippage. A clamping component clamps and fixes the outer wall of the pipe pile. The device uses a moving frame in conjunction with a lifting frame to lift and move the pipe pile, making the overall operation convenient, improving work efficiency, and saving production costs. A telescopic cylinder pushes the lifting block to move up and down, which can drive two limiting rods to insert into both ends of the pipe pile, and simultaneously drive two mechanical claws to clamp and fix the outer wall of the pipe pile.

[0003] However, when the device lifts the steel pipe pile using the limiting rod, the limiting rod only contacts one point of the pipe opening, which makes the pipe opening prone to deformation and affects the connection of the pipe. In contrast, most existing hoisting equipment requires multiple fixing points for the steel pipe pile. Although this makes the hoisting process safer and more stable, the installation and dismantling processes are time-consuming and labor-intensive, resulting in poor practicality. Utility Model Content

[0004] To address the problem of inconvenience in protecting the pipe opening in the existing technology, this utility model provides a steel pipe pile lowering guide lifting device.

[0005] Preferably, the surface of the connecting plate is provided with a track, a hoist is provided on the track, the output end of the hoist is provided with a sling, and the sling is connected to the lifting frame.

[0006] Preferably, two guide rods are symmetrically installed at the bottom of the connecting plate, and two side blocks are symmetrically installed on both sides of the lifting frame. The top of the side blocks has a guide hole, and the guide hole is slidably fitted onto the guide rod.

[0007] Preferably, side frames are installed on both sides of the connecting plate, and a base plate is fixedly installed at the bottom of the side frames. Two movable wheels are symmetrically arranged at the bottom of the base plate, and the two movable wheels are arranged along the length direction of the base plate.

[0008] Preferably, a bidirectional lead screw is rotatably connected within the slot. The bidirectional lead screw is arranged along the length of the lifting frame. Both slide plates are threaded onto the outer wall of the bidirectional lead screw. A worm gear is fixedly mounted on the middle outer wall of the bidirectional lead screw. A worm is meshed on the surface of the worm gear. One end of the worm extends rotatably out of the lifting frame. A motor is provided at one end of the worm. The motor is fixedly installed on the outer wall of the lifting frame.

[0011] In the above technical solution, the end of the rotating shaft away from the second motor is fixedly connected to the turntable.

[0012] The steel pipe pile lowering guide lifting device of this utility model has the following advantages compared with the prior art:

[0013] 1. The steel pipe pile lowering guide hoisting device inserts the inner support into the steel pipe pile, starts the second motor, and drives the turntable to rotate. The turntable drives the slider to slide outward, so that the rubber head is in contact with the inner wall of the steel pipe pile, so that the inner wall of the pipe opening of the steel pipe pile is evenly stressed and the pipe opening is avoided from being deformed.

[0014] 2. The steel pipe pile lowering guide lifting device, by setting guide rods and side blocks, enables the hoist to drive the lifting frame to rise and fall along the direction of the guide rods, thereby playing a guiding role;

[0015] 3. The guide hoist for lowering the steel pipe pile is driven by a motor to rotate the worm gear, which in turn rotates the worm gear and the worm wheel. The worm wheel then rotates the double-sided lead screw, which in turn moves the lifting components on both sides toward the center. This allows the inner support to be inserted into the steel pipe pile and fixed in place for lifting. Attached Figure Description

[0030] Working principle: All electrical components mentioned in this application are externally connected to a power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions of this utility model before use. Before use, the user moves the hoist 6 to a suitable position via the track 5, then connects it to the lifting frame 2 via the sling 10, and inserts the guide rod 16 into the side block 15 to complete the preparation. During use, the user moves the lifting device to the hoisting location via the moving wheels 9, and the hoist 6 drives the sling 10 and lifting frame 2 downwards. During descent, the guide rod 16 and the side block 15 work together to vertically raise and lower the lifting frame 2.

When the connecting rods 42 are aligned with the pipe opening of the steel pipe column, start the motor 11. 1 drives the worm gear 12 to rotate, the worm gear 12 meshes with the worm wheel 13, the worm wheel 13 drives the double-sided lead screw 14 to rotate, the double-sided lead screw 14 drives the slide plate 41 to slide in the slot 3, so that the connecting rod 42 gradually extends into the steel pipe column. When the inner support 44 is completely inserted into the steel pipe column, the motors 43 on both sides are started. The motors 43 drive the rotating shaft 446 to rotate, so that the rotating shaft 446 drives the turntable 445 to rotate. The arc-shaped hole 447 on the surface of the turntable 445 rotates with the turntable 445. The inner wall of the arc-shaped hole 447 presses the inner slider 448, so that the inner slider 448 drives the slider 443 to slide outward in the slide groove 442 until the rubber head 444 is in contact with the inner wall of the steel pipe column. When all the rubber heads 444 are in contact with the inner wall of the steel pipe column, the steel pipe column is fixed. Then, the lifting frame 2 is raised by the hoist 6.
