[0002] Pump pipe is short for concrete conveying pump pipe, a new type of construction engineering accessory product. It is divided into truck pump pipe and ground pump pipe. When splicing pump pipe, it is necessary to lift the pump pipe and then connect it to other pump pipes with external bolts. However, the existing pump pipe handling methods are all done manually, which not only increases the workload of people, but also reduces the splicing efficiency. To address this, we propose a portable hook-type lifting device for pump pipe. Utility Model Content

[0012] 1. This utility model places the lifting rod at the bottom of the pump pipe and allows the tapered rod to pass through the installation hole of the pump pipe. The elastic plate will contact the tapered rod, further preventing the pump pipe from falling during transportation. At the same time, people can insert the external hook through the reserved hole as needed, which facilitates the hoisting of the pump pipe.

[0013] 2. This utility model includes a rust-proof protective layer, comprising an iron oxide phenolic rust-proof coating that provides a first layer of rust protection to the surfaces of the connecting plate, lifting rod, tapered rod, hoisting rod, and elastic plate.
