一种混凝土管吊装装置
The lifting plate is driven to rise and fall by a support plate, a lifting plate, and a threaded rod worm gear transmission system. The concrete pipe is stably clamped by clamping blocks and insert rods, which solves the problem of easy deformation and breakage of the toothed blocks and racks, and improves the stability and safety of the hoisting process.

AI Technical Summary
In existing technologies, the teeth and racks of concrete pipe hoisting devices are prone to bending, deformation, or breakage during long-term hoisting operations, affecting the safety of the hoisting operation.
The system employs a support plate and lifting plate structure, with the lifting plate driven by a threaded rod and worm gear transmission system. Clamping blocks and insert rods are used to stably clamp the concrete pipe, and the combination of pressure rods and moving mechanism enhances the stability of the hoisting.
It improves the stability and safety of the hoisting process, prevents deformation or breakage of the toothed blocks and racks, ensures the stability of the lifting frame's limiting function, and enhances hoisting efficiency and adaptability.

Abstract
Claims
1. A concrete pipe hoisting device, characterised in that: The device includes a support plate and a lifting plate. The support plate has support columns at both ends of its bottom. Threaded rods are rotatably connected to the support columns around a vertical axis. The lifting plate is respectively fitted onto the two threaded rods at both ends. The threaded rods are threadedly connected to the lifting plate. The support plate is provided with a rotating mechanism for synchronously driving the two threaded rods to rotate. Two clamping blocks are slidably connected to each other on the lifting plate. Insert rods are provided on the sides of the two clamping blocks that are close to each other. The lifting plate is provided with a driving mechanism for driving the two clamping blocks to move closer or further apart.
2. The concrete pipe hoisting device according to claim 1, characterized in that: The rotating mechanism includes a worm gear, a worm, and a dual-head motor. The worm gear is coaxially connected to the threaded rod, the dual-head motor is mounted on a support plate, and the worms are respectively connected to the two rotating shafts of the dual-head motor. The two worms respectively mesh with the worm gear on one of the threaded rods.
3. A concrete pipe hoisting device according to claim 1, characterized in that: The drive mechanism includes a double-ended lead screw, a driving gear, a driven gear, and a rotary motor. The double-ended lead screw is rotatably connected to the lifting plate about the sliding direction of the two clamping blocks. Both ends of the double-ended lead screw pass through the two clamping blocks and are threadedly connected to them. The rotary motor is located on the lifting plate. The driving gear is located on the rotating shaft of the rotary motor. The driven gear is coaxially connected to the double-ended lead screw and meshes with the driving gear.
4. A concrete pipe hoisting apparatus according to claim 1, wherein: A pressure rod is slidably inserted into the insertion rod along its own radial direction. Multiple pressure rods are arranged around the axis of the insertion rod. The insertion rod is provided with a moving mechanism for synchronously driving the pressure rods to move.
5. A concrete pipe hoisting apparatus according to claim 4, characterised in that: The moving mechanism includes a movable rod, a connecting rod, and a moving component. The movable rod is slidably connected to the insert rod along the axis of the insert rod. The connecting rod is disposed on the movable rod. One end of the pressing rod extending into the insert rod has an inclined surface, and a slot is formed on the inclined surface. The end of the connecting rod away from the movable rod is slidably engaged in the slot. The moving component is disposed on the insert rod and is used to drive the movable rod to move.
6. A concrete pipe hoisting apparatus according to claim 5, wherein: The moving component includes a sliding sleeve and a return spring. The sliding sleeve is slidably fitted onto the insert rod and is connected to the movable rod. One end of the return spring is connected to the sliding sleeve, and the other end of the return spring is connected to the clamping block. The return spring tends to move the sliding sleeve away from the clamping block.
7. A concrete pipe hoisting apparatus as claimed in claim 4, wherein: The end of the pressure bar away from the insertion rod is provided with an arc-shaped plate, and a buffer pad is provided on the outside of the arc-shaped plate.
