Problems solved by technology

However, the above-mentioned vibration reduction is easily affected by the ambient temperature and humidity, and cannot fully cope with the complex external environment.
In addition, when the load is small, the above technical solution can effectively compensate the vibration of the lower part of the actuator adaptively, but as the load gradually increases, it is limited by the physical properties such as the tensile strength and compressive strength of the material itself, and the preparation process. , the existing vibration damping mechanism is difficult to meet the demand of rigid impact resistance under the high load condition of super-large machinery

Embodiment Construction

[0029] Combine the following Figure 2~6 , the specific content of the present invention will be described in detail through specific embodiments.

[0030] Unloading arm rotation mechanism]

[0031] Such as figure 2 and Figure 2A As shown, the discharge arm slewing mechanism for a bucket wheel excavator mainly includes a support base assembly 2 , an adjustment plate assembly 4 , and an adjustment slewing support assembly 3 from bottom to top. The support base assembly 2 is fixed on the walking mechanism 1 of the equipment itself, and the adjustment plate assembly 4 can rotate the support assembly 3 and the support base assembly 2 automatically through two pairs of upper connecting shafts 46 and lower connecting shafts 44 that are vertically intersected by two pairs of axis lines. Connect adaptively.

[0032] Figure 2A-1 As shown, the center of rotation of the inner turntable 38 is equipped with a freely rotatable central shaft assembly 37. The central shaft assembly 37...

Abstract

A discharging arm rotating mechanism for a wheel bucket excavator is technically characterized in that an adjusting plate assembly is arranged between a supporting base assembly and a rotating supporting assembly, the supporting base assembly is fixed to a walking mechanism of equipment, and a free dip angle within the limited range of the advancing direction can be formed between the supporting base assembly and the adjusting plate assembly; and meanwhile, the adjusting plate assembly and the rotary supporting assembly can freely slide along the upper connecting shaft slide way, and the rotary supporting assembly and the adjusting plate assembly are supported on the supporting base assembly in a self-adaptive mode. The rigid impact of the walking mechanism on the slewing bearing can be effectively reduced in a self-adaptive compensation matching error mode, accumulative errors in the installation, manufacturing and operation processes can be effectively absorbed, the stress condition and meshing transmission precision of the gear are improved, and the overall stability of the bucket-wheel excavator is improved.

Description

technical field [0001] The present invention relates to open-pit mines, cement ports, bulk material storage yards, engineering machinery and equipment, in particular to excavating machinery with centrifugal wheels, rollers or throwers, in particular to a rotary discharge arm for bucket wheel excavators mechanism. Background technique [0002] Such as figure 1 As shown, the invention patent application with application publication number CN1172196A discloses a relatively common bucket wheel excavator, and the manufacturers of this type of excavator mainly include Sandvik (SANDVIK), Krupp (KRUPP) and so on. This type of excavator mainly includes the rotating bucket wheel at the front end that can realize uninterrupted excavation, the receiving conveyor belt that transports the ore in the bucket wheel out, the unloading conveyor belt that guides the ore on the receiving conveyor belt out from the tail, and the unloading conveyor belt. The supporting mechanism of the belt is c...
