Title:
LAUNCHER CATAPULT TRACK DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/052612
Kind Code:
A1
Abstract:
A launcher catapult track device comprises a base (1) and a track (2) located on the base (1). The track (2) can be a single track or can be formed by combining multiple tracks (a, b, c, d, e). The multiple tracks (a, b, c, d, e) are hinge-connected end to end, and extend or retract by collapsing in a lateral direction or a vertical direction of a plane of the track. The track (2) is primarily formed, by means of alignment, insertion and assistive welding, from an upper plate, a lower plate, a left plate, and a right plate (21, 22, 23, 24), and a rib plate (27) therebetween. A rear portion of the track (2) is hinge-connected to the base (1). Two sides of a front portion of the track (2) are coaxially hinge-connected to a pair of balancing hydraulic cylinders (5). The other end of the pair of balancing hydraulic cylinders (5) is coaxially hinge-connected to two sides of the base (1). The launcher catapult track device further comprises a lifting hydraulic cylinder (6). Two ends of the lifting hydraulic cylinder (6) are respectively hinge-connected to the track (2) and the base (1). A hinge shaft of the lifting hydraulic cylinder (6) can be coaxial or parallel to a hinge shaft of the balance hydraulic cylinder (5). The launcher catapult track device has a scientific design, high assembly and manufacturing precision, a light weight, high strength, favorable stability, and low construction costs, and can be easily batch-manufactured.
