Intelligent hoisting method

Technical Field

The invention relates to the technical field of hoisting, in particular to an intelligent hoisting method.

Background

In the process of hoisting heavy objects, such as hoisting large stone carving objects, a gantry crane or a crane is mostly adopted for hoisting. In the hoisting process, the upper end of a hoisted object is bound by using a steel wire rope; or the upper end of the hoisting object is drilled, and the supporting frame is inserted into the transverse drilled hole for hoisting. The hoisting mode easily causes stress points of the hoisted object to be concentrated, and can cause damage to the hoisted object and even fall and overturn under the condition of overlarge local stress.

Disclosure of Invention

s2, the transfer electric pole on the gantry crane realizes the longitudinal movement of the hoisted object;

and S3, transferring a winch on the power output end of the electric pole to realize the lifting movement of the hoisted object.

Preferably, the clamping driving oil cylinder arranged on the clamping fixing cavity of the clamping mechanism drives the clamping frame to clamp the hoisted object.

Preferably, the clamping and positioning motors respectively drive the clamping movable ring bodies arranged up and down to rotate relative to the clamping fixed cavity, so that the clamping frames are respectively inserted into clamping holes of the hoisted objects staggered up and down.

Preferably, the rotating angles of the clamping movable ring body relative to the clamping fixed cavity are detected through encoders respectively.

Preferably, the photoelectric switch is detected through clamping of the front end of the clamping frame, and whether the clamping frame is aligned with the clamping hole of the hoisted object is detected.

Preferably, after the clamping frame is inserted into the clamping hole of the hoisted object, the clamping frame is lifted upwards through the clamping adjusting oil cylinder on the clamping fixed cavity, and whether the clamping frame is attached to the clamping hole or not is detected through the pressure sensor at the upper end of the clamping frame.

The effect provided in the summary of the invention is only the effect of the embodiment, not all the effects of the invention, and one of the above technical solutions has the following advantages or beneficial effects:

1. the technical scheme of the invention can realize clamping and transferring of the hoisted object, and the transferring direction can be flexibly adjusted.

2. In the process that the transfer system clamps the hoisted object, each clamping and positioning motor respectively drives the clamping movable ring bodies which are arranged up and down to rotate through different angles along the clamping fixed cavity so as to realize that the corresponding clamping frames are respectively inserted in the clamping holes of the hoisted object which are staggered up and down; the dangerous situation that the hoisted object is stressed too intensively on a certain transverse surface or vertical surface to be damaged is avoided.

3. The encoders in the transfer system are respectively used for detecting that each clamping moving ring body rotates by an even interval angle, and the clamping detection photoelectric switch is used for detecting whether the clamping frame is aligned with the clamping holes; after the encoder detects that the clamping movable ring body rotates by an optimal angle, if the clamping detection photoelectric switch detects that the clamping frame is not aligned with the clamping hole of the hoisted object, the clamping positioning motor can be used for rotating and fine-adjusting to accurately position the nearest clamping hole.

4. In order to facilitate the clamping frame to enter and exit the clamping hole of the hoisted object, the diameter of the clamping frame is smaller than that of the clamping hole; when the clamping frame enters the clamping hole, the clamping adjusting oil cylinder drives the clamping driving oil cylinder to move upwards, and when the pressure sensor detects that the pressure reaches a certain value, the upper end of the clamping frame is proved to be clamped and fixed with the clamping hole.
