Soundproof safety door for excavator

Abstract

The invention discloses a soundproof safety door for an excavator. The soundproof safety door comprises a door frame which is formed by welding hollow square pipes, the door frame is integrally wedge-shaped, soundproof cotton is arranged in the hollow square pipes, limiting protrusions integrally formed with the corresponding hollow square pipe are symmetrically arranged on the inner wall of each square pipe, section of the soundproof cotton is H-shaped, the soundproof cotton is connected on the limiting protrusions in a clamped manner, a first sealing body is arranged on one side wall of each square pipe, a glass plate is fixedly arranged on the other side wall, corresponding to the corresponding first sealing body, on each square pipe, a second sealing body is arranged on the inner wall, perpendicular to the side walls where the corresponding first sealing body and the corresponding glass plate are positioned, of each square pipe, a cross beam is arranged in the middle of the door frame, a handle is arranged on one side, on which the cross beam is positioned, of the door frame, and hinges are arranged on the other side, on which the cross beam is positioned, of the door frame. Better sealing and soundproof effect is realized through the sealing bodies and the soundproof cotton, and hearing impairment of operating workers is avoided effectively.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a soundproof safety door for an excavator. Background technique [0002] An excavator is an earth-moving machine that uses a bucket to excavate materials that are higher than or lower than the bearing surface, and load them into a transport vehicle or unload them to a stockyard. The materials excavated by the excavator are mainly soil, coal, sediment, and pre-loose soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast. Excavators have become one of the most important construction machinery in engineering construction and are widely used. However, the noise of existing excavators is relatively high during work. Large, but the sound insulation effect of the door of the excavator is poor. After operating the excavator for a period of time, the operator will experience hearing fatigue, which will...

Judging from the development of construction machinery in recent years, the development of excavators is relatively fast. Excavators have become one of the most important construction machinery in engineering construction and are widely used. However, the noise of existing excavators is relatively high during work. Large, but the sound insulation effect of the door of the excavator is poor. After operating the excavator for a period of time, the operator will experience hearing fatigue, which will damage the hearing of the operator over time.
