In addition, the lead core 7 is easy to fall by the mode of binding the lead core 7 by the lifting rope, so that the lead core 7 is damaged, even equipment is crushed, workers are injured by crushing, and installation accidents are caused.
The method for assembling the lead core of the shock insulation support comprises the following steps: firstly, horizontally placing the shock insulation support, enabling a lead core hole 8 on the shock insulation support to be vertical, then clamping one end of a cylindrical lead core 7 by using a hoisting tool, hoisting the lead core 7 by using the hoisting tool, and enabling the axis of the hoisted lead core to be vertical all the time. And hanging the lead core 7 right above the lead core hole 8, then vertically descending the lead core 7, and inserting the lead core 7 into the lead core hole 8. The axial direction of the lead core 7 is ensured to be consistent with the direction of the lead core hole 8 in the lead pressing process, and the scratch of the lead core hole wall by the lead core 7 or the extrusion deformation of the lead core 7 is avoided. The verticality of the lead core 7 is good, the quality of the lead core rubber shock insulation support is guaranteed, the lead pressing qualification rate is improved, and the lead pressing qualification rate reaches 99.5%.
