Problems solved by technology

In addition, since the supporting legs are installed on the side of the working platform, the distance between the pallet at the lower part of the supporting legs and the ground is relatively close, and scratches and collisions are often prone to occur, which affects the appearance and even reduces its service life in severe cases

Abstract

The four-link extended leveling control system includes a working platform, four sets of outriggers and four sets of supporting legs. Each set of supporting legs is connected to the working platform through two extension arms and a set of supporting legs. The platform constitutes a parallel four-bar linkage mechanism. The top surface of the working platform is provided with a level sensor, a proximity switch and a control box. The control box is provided with a PLC controller connected to the level sensor and the proximity switch. The display output device connected with the PLC controller and the RS-485 communication cable, the PLC controller controls the expansion and withdrawal of the outrigger and the support leg through the proximity switch and the level sensor, and displays the horizontal accuracy of the level sensor in the XY direction on the displayed on the output device. Each support leg of the present invention is equipped with a support leg that can be independently deployed and withdrawn, which not only effectively protects the support legs, but also increases the overturning moment of the equipment, further improving the stability of the equipment during operation.

Description

technical field [0001] The invention relates to an electromechanical four-point support leveling device with an expansion mechanism, in particular to a four-link expansion leveling control system. Background technique [0002] At present, the electromechanical automatic leveling system has been used in vehicle radar equipment. Compared with the electro-hydraulic automatic leveling system, it has the advantages of small size, light weight, high reliability, stepless speed regulation, precise leveling, and system power failure. The leveling accuracy can be locked for a long time afterwards; in addition, it also has the advantages of simple processing and maintenance, good environmental adaptability, and low cost. According to actual engineering experience, the supporting legs of the electromechanical automatic leveling system are fixedly installed on the side of the working platform. During installation and disassembly, the working platform needs to be lifted to a certain heig...
