Description

Technical Field

[0001] The utility model relates to the technical field of modern logistics, in particular to a docking mechanism adapted to be assisted by a stacking crane. Background Art

[0002] Stacker crane is an important lifting and transportation equipment in the three-dimensional warehouse. Its main function is to run back and forth in the aisles of the three-dimensional warehouse, storing the material frames filled with goods at the aisle entrance into the cargo compartment of the shelf, or taking out the goods in the cargo compartment and transporting them to the aisle entrance.

[0003] However, for some material frame height positions with special requirements, the material frame is positioned at a lower height. When the AVG trolley delivers the material frame to the bottom of the stacker, the stacker's gripper cannot descend too low to grab the material frame (it cannot sink on the existing foundation), which has a great impact on the normal operation of the stacker. Utility Model Content

[0004] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, the present invention provides a docking mechanism adapted to be assisted by a stacker, so as to facilitate the raising of the material frame height to meet the stacker's grasping requirements.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a docking mechanism suitable for the assistance of a stacker, which is used to lift the height of the material frame, including a lifting frame arranged on the left and right sides of the material frame, and the inner sides of the front and rear ends of the lifting frame are respectively fixed with a support plate for supporting the corner ends of the material frame, and the outer sides of the front and rear ends of the lifting frame are respectively provided with a base, and a screw elevator is installed on the base to synchronously drive the lifting frame to rise and fall.

[0006] In order to achieve synchronous lifting and lowering of the lifting frame, a lifting motor is installed on the base at the front end of the lifting frame. The motor shaft of the lifting motor is connected to the screw lifter on the base at the front end of the lifting frame. The screw lifter on the base at the front end of the lifting frame is connected to the screw lifter on the base at the rear end of the lifting frame through a synchronous shaft.

[0007] Specifically, the lifting frame includes a connecting square tube, columns fixed at the front and rear ends of the connecting square tube, and a lifting block fixed at the upper end of the column. The lifting block is fixedly connected to the upper end of the screw of the screw elevator, so that the lifting frame is lifted and lowered by driving the lifting block to lift and lower by the screw elevator.

[0008] Furthermore, in order to improve the supporting strength of the lifting frame, a crossbeam is fixed between the columns connected to the rear end of the square tube, the support plate at the rear end of the lifting frame is fixed to the rear end of the connecting square tube, and the support plate at the front end of the lifting frame is fixed to the lower end of the column.

[0009] Since the column at the front end of the lifting frame is prone to being compressed and deflected outward during the process of lifting the material frame, a tightening assembly is installed at the front end of the lifting frame. The tightening assembly includes a right-angle seat fixed to the front side of the lower end of the column, and a clamping seat is adjustably installed on the horizontal plate of the right-angle seat. A rubber-coated roller is rotatably installed in the clamping seat, and a tightening bolt that pushes the rubber-coated roller to press against the inner side of the base is connected to the vertical plate of the right-angle seat. This can prevent the column from being compressed and deflected outward.

[0010] Furthermore, the support plate includes two triangular plates fixed on the inner side of the lifting frame at a distance from each other, a flat plate is fixed between the upper ends of the triangular plates, and a guide inclined plate is adjustably provided at the area supporting the material frame on the flat plate, thereby guiding the corner end of the material frame to fall on the flat plate through the guide inclined plate.

[0011] The beneficial effect of the utility model is that the utility model fixes the support plates for supporting the corner ends of the material frame on the inner sides of the front and rear ends of the lifting frame, and the lifting frame is driven to rise and fall synchronously by the screw elevator, thereby achieving the purpose of lifting the material frame to meet the grabbing requirements of the stacker, thereby ensuring the normal operation of the stacker.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0019] like Figure 1 、 Figure 2 The shown embodiment shows a docking mechanism adapted for stacker assistance, which is used to lift the height of the material frame 1 during stacker operation, and includes lifting frames 2 arranged on the left and right sides of the material frame 1. The lifting frames 2 include a connecting square tube 2-1, columns 2-2 fixed at the front and rear ends of the connecting square tube 2-1, and a lifting block 2-3 fixed at the upper end of the column 2-2. A crossbeam 8 is fixed between the columns 2-2 at the rear ends of the two lifting frames 2, so that the rear ends of the two lifting frames 2 form a closed state, and the front ends of the two lifting frames 2 form an open state, so that the AGV trolley can deliver the material frame 1 between the two lifting frames 2.

[0020] Bases 4 are respectively provided on the outer sides of the front and rear ends of the lifting frame 2, and a screw lift 5 is installed on each base 4. A lifting motor 6 is installed on the base 4 at the front end of the lifting frame 2, and the motor shaft of the lifting motor 6 is transmission-connected to the screw lift 5 on the base 4 at the front end of the lifting frame 2. The screw lift 5 on the base 4 at the front end of the lifting frame 2 and the screw lift 5 on the base 4 at the rear end of the lifting frame 2 are transmission-connected through a synchronous shaft 7. The lifting block 2-3 of the lifting frame 2 is fixedly connected to the upper end of the screw of the screw lift 5, so that the lifting frame 2 can be lifted and lowered synchronously when the lifting motor 6 drives the screw lift 5 to lift and lower.

[0021] like Figure 3 As shown, the inner sides of the front and rear ends of the lifting frame 2 are respectively provided with support plates 3 for supporting the corner ends of the material frame 1. Specifically, the support plate 3 includes two triangular plates 3-1 set apart from each other, and a flat plate 3-2 is fixed between the upper ends of the triangular plates 3-1. A guide inclined plate 3-3 is adjustably provided on the flat plate 3-2 at the area supporting the material frame 1 to facilitate guiding the material frame 1 to be placed in the supporting area.

[0022] In particular, the support plate 3 at the rear end of the lifting frame 2 is fixed to the rear end of the connecting square tube 2-1, and the support plate 3 at the front end of the lifting frame 2 is fixed between the lower end of the column 2-2 and the front end of the connecting square tube 2-1.

[0023] Since the front ends of the two lifting frames 2 are not open, during the process of lifting the material frame 1, the columns 2-2 at the front ends of the lifting frames 2 are prone to tilt outward after being subjected to force, causing unstable support at the front end of the material frame 1. For this reason, a tightening assembly 9 is installed at the front ends of the two lifting frames 2.

[0024] like Figure 4As shown, the tightening assembly 9 includes a right-angle seat 9-1 fixed to the front side of the lower end of the column 2-2, and a clamping seat 9-2 is adjustably installed on the horizontal plate of the right-angle seat 9-1. A rubber-coated roller 9-3 is rotatably installed inside the front end of the clamping seat 9-2, and a tightening bolt 9-4 is connected to the vertical plate of the right-angle seat 9-1. By adjusting the tightening bolt 9-4, the rubber-coated roller 9-3 is pressed against the inner side of the base 4, thereby preventing the column 2-2 from being tilted outward due to the force when lifting the material frame 1, thereby ensuring the stable lifting of the material frame 1.

[0025] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
