In order to further shorten the installation and dismantling time of large vehicle mounted radar, improve the survival and combat deployment capabilities of radar vehicles, this paper designs a tarpaulin system, which mainly consists of a lifting mechanism and a tarpaulin skeleton. The tarpaulin skeleton adopts a scissor fork mechanism and a dual guide rail to achieve a 12:1 high compression ratio expansion and contraction of the system. A lifting mechanism consisting of a parallel four-bar linkage actuator, hydraulic system, and electronic control system was designed using electromechanical hydraulic integration design technology. The mechanism is installed at the rear of the vehicle and can complete the loading and unloading of the tarpaulin skeleton within 30 s, achieving rapid transition between the system's working state and transportation state. This system realizes the rapid installation and removal of tarpaulins for vehicle mounted radar, greatly improving the maneuverability of large vehicle mounted radar and providing reference for the design of similar products.
