The invention discloses a ground suction type metal plate drawing machine which comprises a supporting stand column, a manual winch, a fixed base, an air inlet valve, an air pipe, a vacuum generator, a suction cup and trundles. The supporting stand column is installed above the fixed base, the vacuum generator is installed on the upper plane of the fixed base, and the suction cup is installed on the lower plane of the fixed base; an air suction pipe of the vacuum generator is inserted into the suction cup through a hole site of the fixed base, the vacuum generator generates negative pressure after being connected with compressed air, air in the suction cup is pumped away, the suction cup in the vacuum state can firmly fix the equipment to the ground, and through holes are formed in the two sides of the supporting stand column from top to bottom at equal intervals. The proper height of the manual winch is selected according to the maintenance position, the manual winch is fixed to the supporting stand column through the through hole, a traction hook at the front end of the manual winch is connected with a drawing meson melted and planted on a vehicle to be maintained, a driving handle is shaken to generate continuous and stable pulling force, and drawing is conducted according to the actual situation till the sheet metal part is repaired completely.

    本发明公开了一种吸地式钣金拉拔机,包括支撑立柱、手动绞盘、固定底座、进气阀、气管、真空发生器、吸盘、脚轮,所述的支撑立柱安装在固定底座上方,固定底座的上平面安装有真空发生器,下平面安装有吸盘,真空发生器的吸气管通过固定底座的孔位插入吸盘内,真空发生器接入压缩空气后产生负压,抽走吸盘内的空气,处于真空状态的吸盘便可以使设备牢固的固定在地面上,支撑立柱的两侧从上到下开有间距相同的通孔,手动绞盘根据维修位置选择合适的高度,通过上述通孔固定在支撑立柱上,将手动绞盘前端的牵引钩与熔植于待维修车辆上的拉拔介子连接,摇动驱动手柄产生持续稳定的拉力,按照实际情况进行拉拔,直至钣金件被修复完成。
