Problems solved by technology

The slewing platform can turn in any direction on the lower walking mechanism. The slewing platform is equipped with working devices, cabs, engines, counterweights, etc. During the rotation of the excavator, the rotating assembly is used to achieve rotation. However, during the installation process of the existing excavator rotating assembly, since the rotating assembly is relatively large, it cannot be easily fine-tuned during the installation process, thus a lot of time will be wasted in the assembly process

Abstract

The invention discloses a rapid installation auxiliary device for an excavator rotating assembly. The device comprises two supporting frames, bottom plates are welded to the bottoms of the two supporting frames, and clamping grooves are formed in the tops of the two supporting frames. Bearing beams are connected to the inner walls of the clamping grooves in a clamped mode, and electric telescopic rods are connected to the two ends of the bottoms of the bearing beams. First sliding grooves are formed in the outer walls of the tops of the bearing beams, first sliding blocks are embedded in the inner walls of the first sliding grooves, threaded rods are in threaded connection with the middles of the first sliding blocks, and the threaded rods are connected with first servo motors. Through mutual the cooperation of the bearing beams and the electric telescopic rods, a clamped part can be moved up and down, so that adjustment is made convenient, the part is driven by the first servo motors to move within a small range, and the part is driven by second servo motors to rotate. Through the mutual cooperation, rapid fine adjustment can be made in the installation process, and therefore the installation speed is increased.

Description

technical field [0001] The invention relates to the technical field of excavator installation, in particular to an auxiliary device for quick installation of an excavator rotating assembly. Background technique [0002] Construction machinery such as excavators generally need to be equipped with counterweights in order to balance the swing of the machine during operation. The basic structure of a hydraulic excavator has a lower walking mechanism, a slewing platform, a working device, a counterweight, an engine, and a cab. The slewing platform can turn in any direction on the lower walking mechanism. The slewing platform is equipped with working devices, cabs, engines, counterweights, etc. During the rotation of the excavator, the rotating assembly is used to achieve rotation. However, during the installation process of the existing excavator rotary assembly, since the rotary assembly is relatively large, it cannot be easily fine-tuned during the installation process, thus a...
