大型货车的上心盘拆卸作业,是在车体下边把上心盘的紧固螺栓投出,用锤把楔铁打入枕梁和上心盘间,再一步步拆卸。但是由于锈蚀,拆卸作业并不容易。这种作业姿势极不合理,工作效率及安全都存在很多问题,因此设计了专用的拔出装置。本装置如图1所示,包括拔出装置和拔出卡具两部分。拔出装置由油压压头①②、框架③④、框架开关手轮⑤、升降丝杆⑥、升降手把⑦和油泵⑧构成。拔出卡具由可分
Large truck disassembly of the center of the plate, the bottom of the body to the center of the plate bolts set aside, with a hammer to wedge iron into the bolster and the heart of the center, and then step by step removal. However, it is not easy to disassemble due to rusting. This work posture is extremely unreasonable, work efficiency and safety have many problems, so the design of a dedicated pull-out device. The device shown in Figure 1, including the pull-out device and pull out the fixture in two parts. Pull out the device from the hydraulic head ① ②, frame ③ ④, frame switch hand wheel ⑤, lifting screw ⑥, ⑦ ⑦ hand lift and pump ⑧ form. Pull out the fixture can be divided
