Embodiment Construction
[0018] Figure 1 is a schematic diagram of the structure of the large-stroke low-temperature telescopic hydraulic cylinder for the expansion and contraction of the two-section derrick of the 2000-meter skid-mounted drilling rig. The requirements for it are as follows: when used at low temperature (-45°C), the piston stroke length is required to be 14.8 meters. The large-stroke low-temperature telescopic hydraulic cylinder is composed of piston rod head 1, piston rod 2, piston rod bottom 3, piston 4, cylinder barrel 5, gland 6, cylinder bottom 7, and air release plug 8. The piston rod head 1 and the piston rod bottom 3 are respectively inserted into the holes of the piston rod 2 made of steel pipe butt joints and welded together. The piston rod bottom 3 and the piston 4 are connected by screws, and the piston rod head 1 has an oil inlet and outlet port. . The cylinder barrel 5 is made by butt jointing of low-temperature resistant cold-drawn precision seamless steel pipes. The g...
