AI Technical Summary

Technical Problem

Existing lifting tools are difficult to use safely for lifting heavy pipe banks, especially in field environments, which poses a risk of safety accidents. Furthermore, commonly used lifting tools are not suitable for the rectangular shape of pipe banks and cannot effectively prevent slippage during the lifting process.

Method used

A pipe hanger was designed, including a hanging rod, a connecting rod, and a lifting rod. The lever principle is used to convert the weight of the pipe into a clamping force. The hanging rod is inserted into the pipe, and the connecting rod is hinged to the lifting rod to form a clamping structure, which increases the friction to prevent slippage.

Benefits of technology

It achieves safety and stability in pipe hoisting, is suitable for field environments, avoids slippage accidents during hoisting, and has a lightweight and easy-to-operate structure.

Abstract

The utility model relates to hoisting tool's technical field especially, and more particularly to a pipe row hoist, the utility model discloses a pipe row hoist, including inserting and hanging the rod, and the one end of inserting and hanging the rod is equipped with the insertion section for inserting into the pipe spare, and the other end is connected with the connecting rod that is arranged in the angle shape with inserting and hanging the rod, and the one end of connecting rod is away from inserting and hanging the rod and is articulated with the pressure bar, and the one end of pressure bar is equipped with the equipment connection structure for connecting with hoisting equipment, and the other end is the pipe pressing end, when the equipment connection structure of pressure bar is connected on the hoisting equipment and is lifted, the pipe pressing end can be braced tightly on the insertion section of inserting and hanging the rod with the hinge point of pressure bar and connecting rod as fulcrum, because pressure bar actually formed the structure similar to lever, and the gravity of pipe row will part be converted into the pressure of pressure bar to pipe row, and then is converted into friction, thereby can prevent pipe row and slip off, in addition, because the main component is only a few rod-like objects, the pipe row hoist of the utility model has the characteristics of light at the same time, is suitable for field use.
