[0001] This utility model relates to the technical field of steel component processing equipment, specifically a heavy component tilting and lifting device. Background Technology
[0002] In fields such as heavy machinery manufacturing, shipbuilding, bridge engineering, and large steel structure welding, it is often necessary to rotate heavy components (such as large steel plates, beams, columns, and boxes) at multiple angles for welding, processing, and inspection. The problem with traditional manual rotation or simple hoisting methods is their lack of adaptability. Traditional clamps are usually only suitable for workpieces of specific sizes or shapes, making it difficult to flexibly adjust the clamping range and meet the processing requirements of different components.

Detailed Implementation
[0012] like Figure 1 and Figure 2 As shown, a heavy component tilting and lifting device includes a frame 1, a turntable 3, and a clamping structure. A first cavity 101 is provided on the frame 1, and a cover plate 18 is connected to the side of the first cavity 101 by fasteners 18. The turntable 3 is rotatably connected in the first cavity 101, and a clamping structure is provided on the side of the turntable 3. The clamping structure includes a first clamping member and a second clamping member, and the two clamping members cooperate to lock the workpiece to be processed.
[0013] The first clamping component includes a limiting plate 15 for supporting the workpiece and fasteners 17. The limiting plate 15 is detachably fixed to the mounting surface of the turntable 3 by fastening components. A horizontal sliding groove 301 is opened on each of the left and right sides of the turntable 3. A second slider 16 is slidably connected in the sliding groove 301. The second slider 16 is subsequently locked in the sliding groove 301 by fasteners 17 to restrict further movement. The limiting plate 15 is then moved horizontally within the sliding groove 301 to adjust the distance between the left and right limiting plates 15, and then fastened together by fasteners 17. The second clamping component includes guide rods 13, a first slider 12, a top plate 14, and a drive cylinder 11. The connections of each component are as follows: Two guide rods 13 are provided, arranged in parallel, each guide rod 13... The two ends of the guide rod 13 are connected to the turntable 3 through fixed seats; the first slider 12 is slidably mounted on the two guide rods 13, and the top plate 14 is installed on the side of the first slider 12 facing the limiting plate 15. The cylinder body of the drive cylinder 11 is fixed on the turntable 3, and its piston rod is connected to the first slider 12 for driving the first slider 12 to move along the guide rod 13 to adjust the clamping distance between the top plate 14 and the limiting plate 15. In order to provide support for both ends of the top plate 14, an oblique support assembly is designed. The oblique support assembly includes two oblique support rods 19 symmetrically distributed about the central axis of the drive cylinder 11. The two oblique support rods 19 are distributed in a figure-eight shape. The lower end of each oblique support rod 19 is hinged to the back side of the top plate 14, and the lower end of the oblique support rod 19 is connected to the slider through a ball joint.
[0014] like Figure 1As can be seen, after the above two clamping components clamp the workpiece, in order to facilitate the rotation of the turntable, change the workpiece flipping angle, and lock its position after flipping, the following rotary drive mechanism is designed, which includes a worm wheel 2, a worm 4, and a drive motor 5. The worm wheel 2 is fixedly sleeved on the rotating shaft of the turntable 3, and the worm 4 is installed in the first cavity 101 through a bearing seat, forming a worm wheel and worm pair with the worm wheel 2. The drive motor 5 is connected to the worm 4 through a coupling and is used to drive the turntable 3 to perform circumferential flipping motion.
[0015] like Figure 1 As can be seen, two sets of support components are symmetrically arranged inside the first cavity 101. The two sets of support components are the first support structure 9 and the second support structure 10. The first support structure 9 and the second support structure 10 are located on both sides of the center line of the turntable 3. Each set of support structures includes an electric telescopic rod 6. One end of the electric telescopic rod 6 is hinged in the first cavity 101, and the other end of the electric telescopic rod 6 is hinged to a guide wheel 7. The wheel surface of the guide wheel 7 rolls in contact with the end face of the turntable 3. A support rod 8 is hinged on the guide wheel 7. The bottom of the support rod 8 is hinged to the inner wall of the first cavity 101, thereby ensuring that the turntable 3 rotates more stably.
[0016] Working principle: The working principle of this heavy component tilting lifting device can be broken down into the following steps, which will be explained in conjunction with the three major functional modules of clamping and positioning, tilting adjustment, and stable support: Horizontal adjustment: According to the width of the workpiece, loosen the fasteners 17 in the sliding grooves 301 on both sides, manually slide the second slider 16 to drive the limiting plate 15 to move horizontally, adjust the distance between the two limiting plates 15 to fit the two sides of the workpiece, and then tighten the fasteners 17 to fix the position. Longitudinal clamping: The drive cylinder 11 pushes the first slider 12 to move along the guide rod 13 towards the limiting plate 15, causing the top plate 14 to press against the front end of the workpiece, forming a three-point clamping (limiting on both sides + pressing at the front end) with the limiting plate 15. The diagonal brace 19 adaptively adjusts its angle through a ball joint, enhancing the rigid support of the top plate 14, preventing eccentric deformation, and adapting to the positioning of workpieces of different sizes and shapes; Tilting Angle Control: The drive motor 5 drives the worm gear 4 to rotate via a coupling. The worm gear 4 meshes with the worm wheel 2 fixed on the shaft of the turntable 3, converting the horizontal rotational motion into the vertical circular motion of the turntable 3, thus achieving 0°-360° rotation of the workpiece. The reverse self-locking characteristic of the worm wheel pair ensures that the workpiece can be stopped immediately and maintained at any angle without the need for an additional braking device. By precisely starting and stopping the drive motor 5 (such as a servo motor or stepper motor with an encoder), the workpiece can be controlled to stay at a specified tilt angle to meet processing requirements. The self-locking characteristic of the worm wheel pair ensures that the tilting angle is precisely controllable and can be stably locked at any position. Dynamic stability support: The electric telescopic rods 6 in the two sets of support components dynamically extend and retract according to the rotation angle of the turntable 3. During rotation: the electric telescopic rods 6 extend or retract, pushing the guide wheel 7 to always keep in contact with the end face of the turntable 3, reducing friction through rolling contact; the support rod 8, the guide wheel 7, and the bottom of the cavity form a triangular stable structure, dispersing the radial load of the turntable 3 and preventing overload of the rotating shaft; the two support components are arranged on both sides of the center line of the turntable 3 to balance the eccentric torque during the rotation process and suppress vibration. The follow-up support mechanism composed of the electric telescopic rods and the guide wheel enhances the stability of the turntable and prevents vibration or eccentric load during the rotation process.
