The invention discloses a small civil helicopter warehouse-out tractor which comprises a tractor body, a telescopic driving mechanism is mounted on the tractor body, a U-shaped frame is mounted on the telescopic driving mechanism, and four helicopter supporting mechanisms are symmetrically mounted on the inner wall of the U-shaped frame; each helicopter supporting mechanism comprises an L-shaped plate fixedly arranged on the inner wall of the U-shaped frame, the top of the L-shaped plate is fixedly connected with a first hydraulic cylinder, the inner wall of the U-shaped plate is fixedly connected with a transverse rod, the inner wall is rotationally connected with a lead screw, and the side wall is fixedly connected with a first motor in shaft connection with the lead screw; a movable block slidably connected with the cross rod in a penetrating mode is connected to the outer wall of the lead screw in a threaded and penetrating mode, and a second hydraulic cylinder is fixedly connected to the side wall of the movable block in a penetrating mode. The invention relates to the technical field of tractors. The problems that when a small civil helicopter is pulled out of a warehouse, a traction frame needs to be arranged below an undercarriage of the helicopter, then the helicopter is lifted, efficiency is very low, and operation is very troublesome are solved.
本发明公开了一种小型民用直升机出库牵引车,包括有牵引车,牵引车上安装有伸缩驱动机构,伸缩驱动机构上安装有U型车架,U型车架的内壁均对称安装有四个直升机支撑机构;直升机支撑机构包括有固定设置于U型车架内壁的L型板,L型板的顶部固定连接有第一液压缸,U型板的内壁固定连接有横杆,以及内壁转动连接有丝杆,以及侧壁固定连接有与丝杆轴接的第一电机,丝杆的外壁螺纹穿接有与横杆为滑动穿接的活动块,活动块的侧壁固定穿接有第二液压缸,本发明涉及牵引车技术领域。本发明,解决了小型民用直升机出库牵引时,需要将牵引架置于直升机起落架的下方,然后再抬升直升机,效率非常低,操作起来很麻烦的问题。
