Detailed implementation manners

[0026] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Such as Figure 1As shown in the figure, the AGV electric control stacker forklift in the prior art includes a stacker forklift mast 1 in the vertical direction. A fork 2 is movably installed on one side of the stacker forklift mast 1, and the fork 2 can vertically lift relative to the stacker forklift mast 1. A control mechanism 3 is fixedly installed on the other side of the stacker forklift mast 1. The AGV electric control stacker forklift can be manually controlled in the manual mode through the control mechanism 3. The electric control cabinet 4 is fixedly installed at the top of the side of the stacker forklift mast 1 where the control mechanism 3 is installed. When manually controlling the AGV electric control stacker forklift in the manual mode, the electric control cabinet 4 will block the operator's line of sight, posing a certain safety hazard.

[0028] As Figure 2 , 3 , as shown in Figure 4, the present invention provides an AGV electric control stacker forklift with a new structure. The original electric control cabinet 4 is improved into an upper panel 5 of the electric control module and the electric control module. And by making full use of the space of the vehicle body cabinet 6, the electric control module is installed in the vehicle body cabinet 6 at the lower part of the forklift, and the upper panel 5 of the electric control module is fixedly installed at the top of the vehicle body cabinet 6 above the electric control module. A side door 14 of the vehicle body cabinet is opened on the left side of the vehicle body cabinet 6. The position corresponding to the side door 14 of the vehicle body cabinet is the battery compartment. A battery 15 is movably installed in the battery compartment, and the battery 15 is installed and fixed in the battery compartment through a side push-pull mechanism. When it is necessary to maintain the battery 15 of the AGV electric control stacker forklift, the side door 14 of the vehicle body cabinet is opened, and the battery 15 is taken out from the side of the vehicle body cabinet 6 through a battery replacement trolley. Such a design can make full use of the upper space of the battery compartment, providing an installation position and a large enough space for the electric control module. In order to facilitate the battery replacement trolley to take out or put in the battery 15 from the side of the battery compartment, a lifting ring 16 is welded to the top of the battery 15. The electric control module includes a distribution board 17 and electric control components 18 fixedly installed on the distribution board 17. The distribution board 17 is fixedly installed above the battery 15, and the upper panel 5 of the electric control module is fixedly installed above the distribution board 17. Figure 3 The front, top and side of the vehicle body cabinet 6 are made transparent, and the side door of the vehicle body, the side panel and the internal electric control components 18 are hidden. Such a layout not only makes full use of the space above the battery compartment that was originally ignored, but also avoids the problem that the electric control cabinet 4 in the prior art blocks the operator's line of sight.

[0029] As Figures 5 - 9As shown, the distribution board 17 includes an upper distribution board 7 and a lower distribution board 13. On both sides in the length direction of the upper distribution board 7, wire ducts 9 are fixedly installed by screws respectively. An electric control element mounting seat 8 is fixedly installed by screws in the middle of a pair of wire ducts 9. The electric control element mounting seat 8 is arranged parallel to the wire ducts 9. The electric control element mounting seat 8 is a standard part and can adopt a rail made of iron. The bottom of the electric control element 18 has a matching clamping structure (an existing industry standard structure), and the electric control element 18 is clamped on the electric control element mounting seat 8. The pipe cavity of the wire duct 9 is used for wiring. In order to optimize the layout of the electric control element 18, the distribution board 17 of the embodiment of the present invention adopts an upper and lower layered design to make full use of the space of the vehicle body cabinet 6 above the battery 15 and realize a reasonable partition of the electric control element 18. The distribution board 17 is divided into two layers. Key control elements such as an industrial personal computer, a serial port module, and a main board are placed on the upper distribution board 7, and auxiliary devices such as a terminal block, a switching power supply, a bus adapter, and a safety relay are placed on the lower distribution board 13. The wire ducts 9 and the electric control element mounting seat 8 are both existing general components. Which specific components are adopted and the specific positions set can be flexibly adjusted according to different forklift models and different functions.

[0030] Horizontal left support plates 11 and right support plates 12 are arranged at appropriate heights on both sides of the inner wall of the vehicle body cabinet 6. The left support plate 11 and the right support plate 12 are fixedly installed on the inner wall of the vehicle body cabinet 6 by bolts or welding. The main bodies of the upper distribution board 7 and the lower distribution board 13 are rectangular flat plates. At both ends in the length direction of the lower distribution board 13, support seats two 23 are integrally formed. The support seats two 23 are L-shaped structures extending outward on both sides. A weight reduction hole is opened in the middle position of the vertical plate of the support seat two 23. The weight reduction hole can not only reduce the weight of the lower distribution board 13, but also facilitate grasping and moving the lower distribution board 13. Through holes are opened on the horizontal plates of the support seats two 23, and both ends of the lower distribution board 13 are fixedly connected to the left support plate 11 and the right support plate 12 on both sides by bolts. Limited convex eaves 22 are integrally formed and processed at both edges in the length direction of the lower distribution board 13. The limited convex eaves 22 play a role in limiting and protecting the electronic components installed on the lower distribution board 13. Hinge seats 20 and support seats one 21 are integrally formed at both ends in the length direction of the upper distribution board 7. The hinge seats 20 and the support seats one 21 are L-shaped structures extending outward on both sides. The hinge seat 20 is located at the right end. Through holes are opened on the horizontal plates of the hinge seats 20. Both ends of the hinge 10 are fixedly installed on the right support plate 12 and the hinge seat 20 by bolts respectively. By setting the hinge 10, the upper distribution board 7 can be conveniently lifted to facilitate the maintenance or replacement and installation of the electric control elements 18 on the lower layer. When the upper distribution board 7 is placed horizontally, the support seat one 21 is lapped on the left support plate 11 to provide a left support force. A rectangular hole 19 is opened at the right end of the rectangular flat plate of the upper distribution board 7. The rectangular hole 19 can provide an installation space for the electronic components with a higher height on the lower layer (such as a controller).

[0031] The electric control components 18 in the lower layer are installed on the upper surface of the lower distribution panel 13 by bolts. The specific positions of the screw holes can be designed differently according to different component arrangements. Such a two-layer design not only makes the internal layout of the vehicle body cabinet 6 clearer and more orderly, but also improves the space utilization rate, and is convenient for subsequent maintenance and management.

[0032] The upper panel 5 of the electric control module is fixedly installed above the upper distribution panel 7. The upper panel 5 of the electric control module can be fixedly installed at the top of the vehicle body cabinet 6 through a clamping structure or bolts. The upper panel 5 of the electric control module is electrically connected to the electric control components 18 through connecting wires to achieve data interaction.

[0033] Figure 2 In [the figure], the rectangular component on the mast 1 of the reach forklift is a touch screen. The touch screen is generally installed on the outer shell of the vehicle body cabinet 6. If the touch screen is large in size, it is installed on the mast 1 of the reach forklift. The touch screen has nothing to do with the technical improvement of the present invention.

[0034] In the embodiments of the present invention, the technical features not described in detail are all prior arts or conventional technical means, and will not be elaborated here.
