The invention discloses a hoisting tool. The hoisting tool comprises a hoisting ring, a sleeve, an annular petal, a pressing screw rod and a guide rod. The sleeve is in an inverted cylinder shape, and the hanging ring is fixed to the outer side of the bottom of the cylinder. The annular petals are arranged in the sleeve at intervals, anti-skid grooves are formed in the inner sides of the annular petals, radial screw holes and guide holes are formed in the periphery of the sleeve, the pressing screw rods are connected with the screw holes in a matched mode, and the top ends of the pressing screw rods abut against the annular petals to press the pencil lead. The method for assembling the lead core of the shock insulation support comprises the step of clamping one end of the lead core by utilizing a hoisting tool. When the hoisting tool is hoisted, the other end of the lead core is exposed out of the lower portion of the hoisting tool and is always in the vertical direction, and the lead core can be conveniently and smoothly inserted into the lead core hole of the shock insulation support. It is guaranteed that the axial direction of the lead core is consistent with the direction of the lead core hole in the lead pressing assembly process of the shock insulation support, the wall of the lead core hole is prevented from being scratched by the lead core or the lead core is prevented from being extruded and deformed, the quality of the lead core rubber shock insulation support is guaranteed, and the lead pressing qualification rate is increased.
本发明涉公开了吊装工装,吊装工装包括:吊环、套筒、环形瓣、压紧螺杆及导向杆。套筒为倒置的圆筒形,吊环固定在圆筒形底部的外侧。多个环形瓣间隔设置在套筒内,环形瓣的内侧设置有防滑槽,套筒周边设置有径向的螺孔和导向孔,压紧螺杆与螺孔配合连接,压紧螺杆的顶端顶在环形瓣上,将铅芯压紧。本发明的隔震支座铅芯装配方法:是利用吊装工装夹持铅芯的一端。当吊起吊装工装时,使铅芯另一端从吊装工装下方露出,并始终处在垂向,便于铅芯顺利插到隔震支座的铅芯孔内。确保隔震支座在压铅组装过程中,铅芯轴向与铅芯孔的方向一致,避免铅芯孔壁被铅芯刮伤或铅芯被挤压变形,保证铅芯橡胶隔震支座质量,提高压铅合格率。
