The front end of the platform is connected with the support rod through the middle cross rod, the rear end is connected with the support rod through the short cross rod, the support rod is connected with each other through the long cross rod, the middle cross rod and the short cross rod to form a scissor structure, and the hydraulic cylinder is connected with the base , The hydraulic rod is installed in the hydraulic cylinder, and the hydraulic rod is connected with the base through the long cross rod and the base is fixed on the whole body. The hydraulic rod is driven by the oil pressure to move backward along the hydraulic cylinder, which drives the long cross rod connected to the base to move along the base groove. Similarly, when the hydraulic rod moves forward along the hydraulic cylinder under oil pressure, the overall scissor structure retracts to achieve the overall lowering function.
货叉前移部分包括前移部分车体、导轨轮架、导轨轮、电机、联轴器、丝杠、丝杠滑块和轴承座。电机固定在液压式剪叉抬升平台，电机与联轴器相连，之后与丝杠相连，电机通过联轴器带动丝杠转动，使丝杠滑块实现前移和后退功能，丝杠滑块与前移部分车身相连，带动前移部分车身前移，导轨轮固定在前移部分车身，安装在导轨轮架上，所述导轨轮架固定在液压式剪叉抬升平台，起到导向和分担载荷作用。The forward moving part of the fork includes the forward moving part of the body, the guide wheel frame, the guide wheel, the motor, the coupling, the lead screw, the lead screw slider and the bearing seat. The motor is fixed on the hydraulic scissor lift platform. The motor is connected with the coupling, and then connected with the lead screw. The motor drives the lead screw to rotate through the coupling, so that the lead screw slider can achieve forward and backward functions. The forward-moving part of the body is connected to drive the forward-moving part of the body to move forward. The guide wheel is fixed on the forward-moving part of the body and is installed on the guide wheel frame. The guide wheel frame is fixed on the hydraulic scissor lift platform to guide and share the load. effect.
叉车处于初始状态时，剪叉结构收缩，推拉式电磁铁通电，两弧形夹抱杆将前移部分底板夹抱住。叉车运动到指定装载货物的地点后，液压杆受油压驱动，带动长横杆移动，剪叉结构展开，剪叉平台上升。上升到指定高度之后，货叉前移，装载货物，货叉收回，剪叉结构收回，翻转压稳部分在电机驱动下沿丝杆和导轨上升，到达指定位置后翻转部分电机驱动，翻转板沿导向板指定路径翻转，压稳货物，若翻转板高度过高，上升部分电机反向驱动，使翻转板整体下降，压稳货物，完成叉货过程。货叉有旋转要求时，推拉式电磁铁断电，弹簧弹开，两弧形夹抱杆张开，与中间主动齿轮相连的电机驱动齿轮，带动轮系转动，上部货叉整体转动，带动三滑块沿弧形导轨转动，同时分担载荷，旋转到指定位置后，推拉式电磁铁通电，弹簧收缩，两弧形夹抱杆收缩夹抱，保证稳定。当叉车需要卸货时，按照叉车上述叉货过程反向进行即可卸货。此为本发明完整的实施步骤。When the forklift is in the initial state, the scissor structure shrinks, the push-pull electromagnet is energized, and the two arc-shaped clamp bars hold the forward-moving part of the bottom plate clamp. After the forklift moves to the designated location for loading the goods, the hydraulic rod is driven by the oil pressure to drive the long horizontal rod to move, the scissor structure unfolds, and the scissor platform rises. After rising to the specified height, the fork moves forward, loads the goods, retracts the fork, and retracts the scissor structure. The designated path of the guide plate is turned over to stabilize the goods. If the height of the overturning plate is too high, the motor of the ascending part will be driven in the reverse direction, so that the entirety of the overturning plate will be lowered, the goods will be stabilized, and the forklift process will be completed. When the fork is required to rotate, the push-pull electromagnet is powered off, the spring springs open, the two arc-shaped clamping rods are opened, and the motor connected with the middle driving gear drives the gear to drive the wheel train to rotate, and the upper fork rotates as a whole, driving the three. The slider rotates along the arc guide rail, and shares the load at the same time. After rotating to the designated position, the push-pull electromagnet is energized, the spring contracts, and the two arc clamp rods contract and clamp to ensure stability. When the forklift needs to unload the goods, the forklift can be unloaded in the reverse direction according to the above forklift process. This is the complete implementation step of the present invention.
