Therefore, a concrete pipe lifting tool is proposed.
[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

This allows the two pipe port clamping hooks to clamp the concrete pipe 3 along its length. Simply fix the main rope 21 to the lifting equipment such as an excavator, and the concrete pipe 3 can be lifted horizontally in conjunction with the lifting equipment. The operation is simple and convenient; no special loading and unloading machinery is required, reducing construction costs. During the loading and unloading of the concrete pipe 3, since the two ports of the pipe are fixed and clamped by the pipe port clamping hooks, the lifted concrete pipe 3 is kept horizontal, effectively avoiding damage to the pipe openings caused by tilting and bumping into foreign objects during loading and unloading.

[0031] As a preferred embodiment of this utility model, the angle between the connection point of the third plate 13 and the second plate 12 and the direction toward the concrete pipe 3 is greater than 90° and less than 180°.
[0032] The angle between the connection point of the third plate 13 and the second plate 12 and the direction towards the concrete pipe 3 is an obtuse angle, which ensures that the overall force of the lifting device is more closely aligned with the concrete pipe 3, thereby ensuring stability during lifting. This angle is related to the length of the suspension rope; the longer the suspension rope, the smaller the angle. In a preferred embodiment of this utility model, it is preferably 120°. In actual use, this angle can be flexibly adjusted according to actual needs, and this utility model does not impose any particular limitation on it.

[0041] U-shaped clips are commonly used connectors between ropes and holes. They facilitate the fixed connection between the rope and the connecting hole. However, other structures can be used instead of U-shaped clips, such as connecting rings or knots at the ends of the rope. This invention does not impose any particular limitation on these methods. The diameter of the connecting hole 8 is preferably 15mm.
[0042] In a preferred embodiment of this utility model, the first plate 11, the second plate 12, and the third plate 13 are all made of steel plates. Preferably, they are made of steel plates with a diameter of 15mm, which are sturdy, durable, and readily available on site.

[0045] As can be seen from the above specific embodiments, the concrete pipe lifting tool provided by this utility model, through the structural design of the clamp, allows for the lifting of concrete pipes by inserting the first plates of a pair of pipe end clamping hooks into the two ends of the concrete pipe, and using the two second plates to fix the two ends of the concrete pipe. This enables the two pipe end clamping hooks to clamp the concrete pipe along its length. Simply fix the main rope to a lifting device such as an excavator, and the concrete pipe can be lifted horizontally in conjunction with the lifting equipment. The operation is simple and convenient; no special loading and unloading machinery is required, reducing construction costs. During the loading and unloading of the concrete pipe, the two ends of the pipe are fixed and clamped by the pipe end clamping hooks, ensuring that the lifted concrete pipe remains horizontal, effectively preventing damage to the pipe openings caused by tilting and bumping into foreign objects during loading and unloading. Furthermore, there is no need to drill holes in the concrete pipe, better protecting the integrity of the pipe, saving drilling time, and improving work efficiency.
