Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, in particular to a position tracking device for a grab-type ship unloader. Background Art

[0002] A ship unloader utilizes a continuous conveying mechanism to create a head capable of lifting bulk materials. It can also be equipped with self-retrieving capabilities or equipped with retrieving and feeding devices. This allows the bulk materials to be continuously lifted from the ship's hold and then unloaded onto a boom or frame for transport to the shore's main conveyor system. Using a ship unloader significantly improves unloading efficiency, minimizes dust pollution, and maintains a clean environment, resulting in high efficiency and environmental protection.

[0003] The grab bucket may become unstable when it descends during the process of grabbing and unloading materials. At the same time, the grabbing point is inaccurate, and leakage of materials after grabbing may often occur. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a position tracking device for a grab-type ship unloader hoist.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a grab-type ship unloader sling position tracking device, including: a beam, a frame and a grab, the frame is provided with a beam, the beam is vertically connected to the frame, a circular track is provided at the bottom of the beam, a plurality of grabs are provided on the circular track at the bottom of the beam, a laser radar is provided at the end of the beam, a PLC controller is provided at the top of the beam, and a plurality of tracking locators are provided on the beam.

[0006] In a preferred embodiment of the present invention, the annular track and the grab bucket are connected by a steel rope.

[0007] In a preferred embodiment of the present invention, an encoder is provided on the frame.

[0008] In a preferred embodiment of the present invention, a pulley is provided at the bottom of the frame.

[0009] In a preferred embodiment of the present invention, a sensor is provided on the grab bucket.

[0010] The beneficial effects of the present invention are: the position tracking device for the sling of the grab-type ship unloader of the present invention can transmit the grabbing situation in real time through the laser radar and the sensor during the grabbing process, and can also transmit the locator in real time whether there is any jamming when multiple grabs work on the circular track at the same time, thereby replacing human monitoring. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for describing the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. Among them: Figure 1 The utility model is a schematic diagram of the three-dimensional structure of a preferred embodiment of the position tracking device of the grab ship unloader.

[0012] The components in the accompanying drawings are marked as follows: 11. beam, 12. frame, 13. grab, 14. circular track, 15. laser radar. DETAILED DESCRIPTION
