DETAILED DESCRIPTION

[0014] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used for explaining the utility model and are not used for limiting the range of the utility model.

[0015] As Figs. 1 to 3As shown, this utility model discloses a front-end lifting crane for precise positioning in smart stations, including a crane body 100, a main GPS locator 101, a 5G communication terminal 102, and a secondary GPS locator 201. The crane body 100 is connected to a lifting device 202 via a lifting arm 203. The main GPS locator 101 and the 5G communication terminal 102 are installed on the top of the crane body 100's cab for GPS satellite positioning to ensure accurate positioning. The secondary GPS locator 201 is installed on the lifting device 202. When the lifting device 202 lifts and lowers containers, it moves the secondary GPS locator 201 up and down. The main GPS locator 101 and the secondary GPS locator 201 are respectively connected to the 5G communication terminal 102 for communication. The 5G communication terminal 102 is connected to the smart station system for communication and is used to enhance the signal strength with the smart station system. With the direction of the secondary GPS locator 201 relative to the primary GPS locator 101 as the forward direction, the position, orientation and travel direction of the crane body 100 can be accurately determined by the cooperation of the primary GPS locator 101 and the secondary GPS locator 201, so as to achieve precise control of the crane body 100 and facilitate the handling of containers. The intelligent station system adopts existing technology.

[0016] In this embodiment, specifically, the longitudinal positioning length of the crane body 100 in the horizontal plane is a, a = a1 + a2, where a1 is the horizontal distance between the main GPS locator 101 and the secondary GPS locator 201, and a2 is the distance between the main GPS locator 101 and the rear end of the crane body 100.

[0017] The main GPS locator 101 and the auxiliary GPS locator 201 form a main GPS positioning point 301 and an auxiliary GPS positioning point 302 respectively in the horizontal plane. During the movement of the crane, the positioning points of the main GPS locator 101 and the auxiliary GPS locator 201 are constantly fluctuating. Therefore, the center line that determines the two sides of the crane during the movement is no longer the line connecting the positioning points of the main GPS locator 101 and the auxiliary GPS locator 201. Instead, it forms a main and auxiliary GPS positioning horizontal frame 303 in the horizontal plane with the main and auxiliary GPS positioning horizontal frame 303 as the endpoints. The center line of the main and auxiliary GPS positioning horizontal frame 303 in the horizontal plane is the main and auxiliary GPS positioning center line 304. The lateral positioning width of the crane body 100 in the horizontal plane is the distance b / 2 of the main and auxiliary GPS positioning center line 304 extending to both sides, which further ensures the accuracy of the positioning of the crane body 100. Here, b is the width of the crane body 100, which can be obtained by measuring the crane body 100. By confirming the length and width dimensions of the crane body 100, the area occupied by the crane body 100 can be accurately determined, enabling precise control of the position of the crane body 100 and meeting the usage requirements of the smart container terminal.

[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
