Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the present invention provides a precise positioning method for a monorail crane, which includes an electric hoist 1 with a sensor and a controller, a first positioning point 5, a second positioning point 6, a suspension rope 2, and a track 4 . The specific implementation process is: the electric hoist 1 drives the material 3 to move horizontally to the right through the sling 2 to the container 8, the electric hoist 1 contains a controller and a sensor, and the sensor can detect Positioning point 5 and positioning point 6, when the sensor detects positioning point 5, the controller controls the electric hoist to start changing speed, and makes the electric hoist continue to move forward at a small fixed speed, when the sensor detects positioning point 6 , the electric hoist stops moving forward to achieve positioning.

Abstract

The invention discloses an accurate positioning method of a monorail crane. The accurate positioning method comprises the following steps that positioning of an electric hoist is realized in a mode ofdetecting positioning points by a sensor, the positioning points are the first positioning point and the second positioning point, and when the sensor detects that the electric hoist reaches the position of the first positioning point, a controller controls the electric hoist to enable the electric hoist to start to change speed and keep the speed at a fixed small value until the sensor detects that the electric hoist reaches the position of the second positioning point, and the electric hoist starts to stop positioning. The accurate positioning method has the characteristics of accurate positioning and stable performance, and is simple in structure and easy to implement.

Description

technical field [0001] The invention relates to a positioning method of a factory lifting device, more specifically, the invention and a positioning method of a monorail crane. Background technique [0002] At present, the monorail crane used in the factory adopts a single-point positioning method. Although it can realize the positioning function, its positioning is not accurate enough. Even in the case of accurate positioning, the suspension rope will shake due to the large inertia when stopping. In some cases, when the material to be hoisted needs to be placed in a specific container, the error caused by the single-point positioning method will cause great inconvenience to the hoisting work, or will be accompanied by multiple reworks. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, solve the problem of inaccurate positioning, and the large stopping inertia that causes the hanging rope to shake, whi...
