Embodiment

[0025] Such as figure 1 with image 3As shown, a double-drive body-in-white lifting workbench is used on an automobile welding line, including an underframe 1, a main lifting mechanism, a top platform 2 and a PLC. Described main elevating mechanism is arranged between underframe 1 and top platform 2, and this main elevating mechanism is scissors type elevating mechanism, comprises two groups of scissor arms that are made up of active arm 18 and driven arm 19, and two groups of scissor arms The yoke arms are symmetrically arranged in parallel, and the plane where the scissor arms are located is parallel to the length direction of the underframe 1. In each group of scissor arms, the middle part of the driving arm 18 is hinged with the middle part of the driven arm 19, and the two groups of driving arms 18 and the slave arms are hinged. The hinge points of the movable arms 19 are connected by a connecting rod, and a push rod is connected between the bottom ends of the tw...

Abstract

The invention provides a dual-drive body-in-white lifting working platform. The lifting working platform comprises an underframe, a top platform, a main lifting mechanism which is arranged between the underframe and the top platform and a programmable logic controller (PLC), wherein standby lifting cylinders are respectively arranged at the two ends of the underframe, the free ends of the piston rods of the standby lifting cylinders are connected with the top platform, and the dual-drive body-in-white lifting working platform further comprises an interlocking system for interlocking the main lifting mechanism and the standby lifting cylinders. When the main lifting mechanism cannot normally work due to faults, a power supply state can be switched, the standby lifting cylinders are used to lift the top platform, and the interlocking system is used for limiting the common use of the main lifting mechanism and the standby lifting cylinders, so that the two sets of mechanisms can be prevented from interfering with each other. The lifting working platform has emergency power reserve, so that the dual-drive body-in-white lifting working platform can continuously operate, thus, the shutdown time can be greatly reduced, and the production takt can be followed.

Description

technical field [0001] The invention relates to a kind of automobile production equipment, more specifically, it relates to a double-drive body-in-white lifting workbench. Background technique [0002] The body-in-white lifting workbench is a kind of production equipment widely used in automobile manufacturing enterprises. The body-in-white can be transported in a straight line through the body-in-white lifting workbench, and can also be lifted vertically to perform pin positioning on the work station. The existing body-in-white lifting workbench is usually driven by a motor to achieve lifting, and there is only a single lifting motor. Once the motor or the power transmission system of the motor fails, it will take a lot of time to replace and debug the corresponding parts. In high-paced, On the long-process automobile production line, every second of downtime will cause partial process interruption, disrupt the original production rhythm, and immediately accumulate huge pre...
