Problems solved by technology

When using this method for lifting operations, when there are more than 4 lifting lugs, the heavy object is easy to tilt, and the steel wire rope is broken due to uneven force and wear. It is necessary to constantly adjust the angle between the steel wire rope and the lifting lug; and the installation of the shackle takes time. ;The length of the wire rope is not easy to control
For heavy-duty hoisting, due to the limited force of the wire rope, the diameter of the wire rope is limited, and more lugs must be provided to increase the number of shackles, which cannot be arranged on the hook due to too many shackles.

Embodiment

[0033] Such as image 3 with 4 As shown, the portable heavy lifting rope winding method of this embodiment includes the following steps:

[0034] Step 1. Preparatory work, one hoisting steel rope and no less than one hoisting point steel pipe; the hoisting point steel pipe is located under the main deck of the barge and the hoisting point steel pipes are arranged side by side from bow to stern; in this step, the hoisting rope is 2 windings The steel pipe passing the lifting point is hooked on the hook 4 used for the lifting test, and the steel pipe 3 of the lifting point is located below the main deck of the barge (the weight being lifted). The number of hanging point steel pipes 3 can be determined according to actual operation requirements. The lifting point steel pipe 2 is arranged on the main structure of the barge and is integrally formed.

[0035] Step 2. Fix one end of the hoisting wire rope on the crane hook; this step is to fix the "pipa head" at the head end of the hoist...

Abstract

The invention discloses a portable heavy hoisting rope winding method to solve the technical problems encountered in the hoisting operation process of the hoisting test methods related in the background technology. According to the technical scheme, the portable heavy hoisting rope winding method comprises the following steps that firstly, a hoisting steel rope and more than one hoisting point steel tube are prepared; secondly, one end of the hoisting steel rope is fixed to a hoisting hook of a crane; thirdly, the other end of the steel rope is hoisted, wound around one hoisting point steel tube firstly, then wound back to the hoisting hook and then wound on the next hoisting point steel tube in a penetrating mode; fourthly, the method in the third step is circulated, and the steel rope is wound around all the hosting point steel tubes from the stem to the stern in sequence; fifthly, after the fourth step is completed, the tail end of the hoisting steel rope is fixed to the hoisting hook of the crane. The portable heavy hoisting rope winding method has the advantages that the hoisting steel rope can be adjusted in angle so as to be maintained balanced by a hoisted heavy object according to the inclined condition of the heavy object, and higher safety is achieved compared with that in a traditional method.

Description

Technical field [0001] The invention relates to a portable heavy-duty hoisting rope winding method, which belongs to the field of ships and ocean engineering. Background technique [0002] In the process of the heavy lifting test of the crane on the ship, the lifting lugs are usually welded on the weight to be lifted, and a pair of shackles are connected by a wire rope and a single lifting lug is connected to complete the lifting and displacement. When lifting with this method, when there are more than 4 lifting lugs, the weight is easy to tilt and the wire rope is broken due to uneven force and wear. It is necessary to constantly adjust the angle between the wire rope and the lifting lug; and the installation of the shackle is time-consuming ; The length of the wire rope is not easy to control. For heavy lifting, due to the limited force of the wire rope, the diameter of the wire rope is limited, and more lifting lugs must be provided, thereby increasing the shackles, causing t...
