The invention discloses a rotary disc type damping system for a truck with a loading crane. The rotary disc type damping system comprises a rotary table with a brake disc, a pneumatic caliper disc brake and a pneumatic control system, an annular brake disc is arranged on the outer circumference of a rotary supporting and fixing bottom plate of the rotary table, the pneumatic caliper disc brake is installed on the machine frame, and the upper portion of the pneumatic caliper disc brake is communicated with a control gas circuit of the pneumatic control system. The pneumatic control system comprises a rotary damping button, a damping electromagnetic valve, a brake electromagnetic valve, a pressure regulating valve, a chassis gas storage tank, a rotary lock button, a proximity switch and an operation valve neutral position detection travel switch. According to the rotary speed reducer, the brake disc is arranged to fill the fit clearance after gear engagement to a certain extent, and the brake disc is braked by the pneumatic caliper disc brake, so that inertial shaking of the upper operating device during rotation in the working process is eliminated, and the service life of the rotary speed reducer is prolonged while the driving safety is ensured.
本发明公开了一种用于随车起重运输车的回转盘式阻尼系统,包括带制动盘的转台、气动钳盘式制动器、气动控制系统;所述转台的回转支撑固定底板的外圆周上设置有环形的制动盘,气动钳盘式制动器安装在机架上,气动钳盘式制动器的上部接通气动控制系统的控制气路;所述气动控制系统包括回转阻尼按钮、阻尼电磁阀、制动电磁阀、调压阀、底盘储气罐、回转锁按钮、接近开关、操作阀中位检测行程开关。本发明通过设置制动盘一定程度的填充齿轮啮合后的配合间隙,且通过气动钳盘式制动器对制动盘的制动,消除工作过程中上部操作装置回转时的惯性晃动,确保了行车安全的同时还延长了回转减速机的寿命。
