Mining excavator with cabinet body damping device

Abstract

The invention discloses a mining excavator with a cabinet damping device in the technical field of excavators, comprising a damping shell, the other end of the air pressure damping rod is hinged to a transmission rod through a connecting piece, and the shock absorbing base The four corners of the bottom are equipped with shock-absorbing feet, the top of the shock-absorbing base is uniformly provided with shock-absorbing airbags, the outer walls of the left and right sides of the shock-absorbing shell are symmetrically provided with two sets of adjusting screws with the same structure, and the guide plate is opposite to the top of the inner wall. There are two sets of guide pulleys with the same structure symmetrically to the bottom. The device is easy to operate. Rotate the adjustment screw to make the guide pulleys clamp the frequency conversion cabinet to prevent the frequency conversion cabinet from shaking left and right in the inner cavity of the shock-absorbing shell. The shock-absorbing base passes the shock-absorbing The airbag is equipped with a frequency conversion cabinet, and the shock-absorbing airbag evenly transmits the vibration of the frequency conversion cabinet to the shock-absorbing base. , to improve the stability of the frequency conversion cabinet.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to a mining excavator with a cabinet damping device. Background technique [0002] On large-scale mine-used shovel excavators, the frequency conversion cabinet is the core of the entire electrical system, and the reliability of the frequency conversion cabinet is a key factor for the entire equipment. The frequency conversion cabinet is a key component, controlling the lifting motor, pushing motor, For the normal operation of the slewing motor and the traveling motor, the shock absorption effect of the frequency conversion cabinet in the prior art is not ideal, and the damage of electrical components still often occurs, which seriously affects the working efficiency of the excavator. [0003] In Chinese Patent No. CN204312615U, a cabinet damping device for a mining excavator is proposed, including an upper damping assembly and a lower damping assembly, the upper damping assembly ...

[0002] On large-scale mine-used shovel excavators, the frequency conversion cabinet is the core of the entire electrical system, and the reliability of the frequency conversion cabinet is a key factor for the entire equipment. The frequency conversion cabinet is a key component, controlling the lifting motor, pushing motor, For the normal operation of the slewing motor and the traveling motor, the shock absorption effect of the frequency conversion cabinet in the prior art is not ideal, and damage to electrical components still often occurs, which seriously affects the working efficiency of the excavator

[0003] In Chinese Patent No. CN204312615U, a cabinet damping device for a mining excavator is proposed, including an upper damping assembly and a lower damping assembly, the upper damping assembly is arranged above the frequency conversion cabinet, and the lower damping assembly The shock assembly is arranged under the frequency conversion cabinet. The upper shock absorption assembly includes a diagonal stay rod, a first wire rope shock absorber and an angle steel connector. The first wire rope shock absorber is arranged laterally and one side is connected to the angle steel connection. The vertical section of the piece, the other side of the first wire rope shock absorber is connected to the bottom end of the diagonal stay rod, and the lower shock absorber assembly includes a cabinet assembly, a second wire rope shock absorber and a fixed chassis assembly, The second steel wire rope shock absorber is arranged horizontally and the upper side is connected to the lower end of the cabinet assembly, and the lower side is connected to the upper end of the fixed chassis assembly. The structure of this patent is too simple and the shock absorption is poor, which cannot better protect the frequency conversion Cabinets are easy to fall off and damage the internal parts of the frequency conversion cabinet due to excessive vibration during work, which affects work efficiency. Therefore, we propose a mining excavator with a cabinet shock absorber
