Description

Technical Field

[0001] This utility model relates to the field of loading and unloading lifting tools, and in particular to a plastic corrugated pipe loading and unloading lifting tool. Background Technology

[0002] The outer wall of the corrugated pipe is corrugated. Without drilling, it is a drainage pipe / conduit pipe / fresh air pipe. With drilling, it is a seepage pipe. The corrugated pipe has strong pressure resistance and good pressure resistance. The pipe wall is relatively thin, which saves production raw materials and reduces manufacturing costs. It is mainly used for drainage or seepage / cable sheathing pipes and conduits in municipal engineering, sports fields, parks and other occasions.

[0003] like Figure 1 As shown, corrugated pipes are mostly coiled in rolls at the factory and bundled with three PP straps. During transportation, they are directly loaded into the truck bed using forklift forks. However, because the walls of the corrugated pipes are relatively thin, the forklift forks can damage them during loading and unloading. Furthermore, when loading and unloading coiled corrugated pipes, the forklift forks need to first stand the pipes upright, load them, and then lay the coils down and stack them together, which is quite troublesome.

[0004] Therefore, a plastic corrugated pipe loading and unloading tool is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a plastic corrugated pipe loading and unloading lifting tool with a simple structure and convenient use. It facilitates the horizontal loading and unloading of coiled corrugated pipes by forklifts, avoiding damage to the corrugated pipes by the forklift forks, thereby solving the problems mentioned in the background art.

[0008] A further improvement of this utility model is that the support plate is disc-shaped, three adjusting sleeves are arranged in a circular array at the bottom of the support plate, and the tail of the support rod is provided with several adjusting holes. The tail of the support rod is connected to the adjusting sleeve through a pin A.

[0009] A further improvement of this utility model is that the head bottom of the support rod is connected to an ear plate, and the top of the chain is connected to the ear plate by a shackle.

[0010] A further improvement of this utility model is that the support sleeve is symmetrically connected to the top of the support plate, and both the sleeve and the support sleeve are provided with connection holes. The support sleeve is connected to the sleeve through a pin B.

[0011] A further improvement of this utility model is that a threaded hole is provided at the center of the support plate, a half-threaded screw is fitted into the threaded hole, and a baffle is connected to the top of the screw; a ring is rotatably connected to the smooth part of the screw, the ring is snapped into the bottom end of the baffle, and a lifting lug is connected to the ring.

[0012] A further improvement of this utility model is that a locking nut is connected at the joint between the screw and the threaded hole.

[0013] A further improvement of this utility model is that the bottom end of the adjusting sleeve is connected to a first leg.

[0014] A further improvement of this utility model is that a second leg is connected to the bottom end of the sleeve, and the bottom end of the second leg is flush with that of the first leg.
