1.2吨筒式柴油打桩机(上海工程机械厂生产)在施工中,起火用桩锤钩子是靠起落架上的桩锤杠杆碰撞筒身的上、下两碰块退回和复出的。由于多次碰撞,桩锤杠杆轴易产生扭曲变形。这样将会出现: ①起落架上不去或下不来,无法起火; ②强行起火将使杠杆轴扭断。我单位在使用中将原杠杆与轴固结式(见附图a)改为狗牙式(见附图b),(利用报废的翻斗车方向机摇臂)。这样桩锤杠杆安装不正或多
1.2 ton drum diesel pile driver (manufactured by Shanghai Construction Machinery Factory) During construction, the pile hammer hook for fire is returned and returned by the collision block on the underside of the pile hammer on the landing gear. Due to multiple collisions, the pile hammer lever axis is easily deformed. This will happen: 1 If the landing gear does not go down or down, it cannot catch fire. 2 A forced fire will cause the lever shaft to break. In the use of our unit, we changed the original lever and shaft consolidation (see figure a) to dog-type (see figure b), (using the abandoned dump truck steering wheel rocker). This pile hammer lever is not installed properly or
