Description

An Easy-to-Move Herringbone Mast Hoisting System

technical field

The utility model relates to the technical field of equipment hoisting, and more specifically relates to a moving herringbone mast hoisting system.

Background technique

For hoisting operations such as hoisting equipment in place and loading and unloading objects, the most ideal, most convenient and most efficient method is to use a crane. However, for the lifting of equipment and objects in confined spaces such as narrow construction sites, workshops, warehouses, and frame structures, the crane cannot enter due to its large size, or the crane arm cannot be lifted or rotated, or It is an environment where crane resources are scarce, and cranes cannot be used for lifting operations, and usually only the method of erecting masts can be used for hoisting operations.

Herringbone mast, due to the characteristics of easy disassembly and assembly, good lateral stability, less stable wind ropes required, large lifting capacity, solid and durable, and strong adaptability to narrow construction sites with limited operating space, so the herringbone mast It is more widely used in lifting operations than other forms of masts.

For the hoisting of traditional herringbone masts, the tops of two steel pipes are usually placed crosswise at the hoisting site, and the steel wire ropes are used for multi-turn winding, and slings are hung at the intersections to tie lifting devices such as hoists or pulleys. After the mast is erected, the front and rear Each side needs to pull the cable wind rope, as shown in Figure 1. This hoisting method has the following disadvantages: (1) The traditional herringbone mast and column steel pipes are arranged crosswise, the hoisting load causes pressure off the axis, and the steel pipes are in poor stress state; (2) the traditional herringbone mast The bottom of the mast and column steel pipes are directly placed on the skids, and the two steel pipes are only stressed at two points on the inside (the place indicated by the two arrows at the bottom of Figure 1), causing the steel pipes to bear eccentric pressure, which further makes the steel pipes in a poor state of stress; (3) With traditional herringbone masts, when a lot of equipment is to be hoisted, it is often necessary to dismantle the mast and then reinstall it when hoisting one piece of equipment and then hoisting another piece of equipment. The process is labor-intensive and time-consuming.
