Welding seam treatment equipment for movable arm of excavator

Abstract

The invention discloses welding seam treatment equipment for a movable arm of an excavator. The welding seam treatment equipment for the movable arm of the excavator comprises a machine body, whereina working cavity is formed in the machine body; a pretreatment device capable of carrying out rust prevention treatment on a welding seam of the movable arm of the excavator is arranged at the upper side of the working cavity; and the pretreatment device comprises a pretreatment box arranged at the upper side of the working cavity and capable of carrying out grinding, rust removal and antirust paint spraying on the welding seam of the movable arm of the excavator. According to the invention, a driving device is arranged, a threaded rotating shaft I, a threaded rotating shaft II and a hydrauliccylinder can be driven to drive the pretreatment box to move in different directions, and therefore a grinding head, a rust removal liquid spray head and a paint spray head are driven to carry out welding seam grinding, rust removal and antirust paint spraying operation on the welding seam of the excavator separately; a conveying device is arranged, and the movable arm of the excavator can be conveyed through a conveying belt; and a clamping device is arranged, and the movable arm of the excavator can be damped, clamped and fixed through a fixed clamping block arranged at the upper side of aclamping arm.

Description

technical field [0001] The invention relates to the technical field related to excavators, in particular to welding gap processing equipment for excavator arms. Background technique [0002] An excavator, also known as a backhoe, is an earth-moving machine that uses a bucket to excavate materials that are higher or lower than the bearing surface, and load them into transport vehicles or unload them to the stockyard. The materials excavated by excavators are mainly soil, coal, sediment, and pre-loosened soil and rocks; from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become the most popular in engineering construction. One of the main construction machinery; the three most important parameters of the excavator; operating weight (mass), engine power and bucket capacity; among them, the excavator arm is the most easily damaged driving part of the excavator, check the excavator motor When the w...

Problems solved by technology

The materials excavated by excavators are mainly soil, coal, silt, and pre-loosened soil and rocks; from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become the most popular in engineering construction. One of the main construction machinery; the three most important parameters of the excavator; operating weight (mass), engine power and bucket capacity; among them, the excavator arm is the most easily damaged driving part of the excavator, check the excavator motor When the welding seam of the arm side plate is rusted and cracked, it is necessary to scrape off or polish the surface paint and rust of the weld seam, while the grinding, rust removal and spraying of anti-rust paint on the weld seam of the general excavator arm are generally performed manually. , this operation is time-consuming and laborious, and the efficiency is relatively low, so it is necessary to design a weld gap treatment equipment for the excavator arm
