Positive and negative passive compensation device for deflection deformation of large and heavy horizontal ram

The invention discloses a large and heavy horizontal ram flexural deflection positive and negative passive compensation device which comprises an upper pull rod device and a lower push rod device, and the upper pull rod device and the lower push rod device are both installed in a ram. The upper pull rod device is used for applying tensile force to the front end of the ram to resist deformation of the ram during overhanging; the lower push rod device is used for applying thrust to the front end of the ram to prevent the ram from deforming during overhanging; the ram is symmetrically provided with an upper pull rod device and a lower push rod device. The positive and negative compensation device for the deflection deformation of the ram has the characteristics that additional axial deformation is not generated while the deflection deformation of the ram is compensated, and the rigidity of the ram is enhanced. 本发明公开了一种大重型卧式滑枕挠曲变形正负被动补偿装置，包括上部拉杆装置和下部推杆装置，所布置的上部拉杆装置和下部推杆装置都安装在滑枕内部；所述上部拉杆装置用于给滑枕前端一个拉力抵抗滑枕悬伸时的变形；所述下
