Abstract

The invention discloses a lock rod seat welding auxiliary structure of an electric shovel bucket and an installation method, and belongs to the technical field of engineering machineries. The auxiliary structure comprises a bucket door body and a bucket door rib plate; the auxiliary structure is characterized in that a lock rod seat positioning block is welded in the bucket door body and is provided with a positioning surface; a lock rod seat is arranged on the side portion of the lock rod seat positioning block, the distance d between the lock rod seat and the positioning face of the lock rodseat positioning block is larger than or equal to 1 mm and smaller than or equal to 2 mm; a jackscrew support is welded to the bucket door rib plate, the contact length l of the jackscrew support andthe bucket door rib plate is larger than or equal to 100 mm and smaller than or equal to 200 mm, a jackscrew is assembled on the jackscrew support through threads, and the front end of the jackscrewis opposite to the lock rod seat; and a locking rod seat positioning fine adjustment device is welded to the lower side of the locking rod seat, and the locking rod seat positioning block and the locking rod seat positioning fine adjustment device are located at the two symmetrical end faces of the jackscrew support respectively. The auxiliary structure can effectively improve the installation andfixing efficiency of the lock rod seat.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering equipment, and in particular relates to a welding auxiliary structure of a lock bar seat of an electric shovel bucket. Background technique [0002] Electric shovels are also called rope shovels and cable shovels, that is, mechanical electric excavators are single-bucket excavators that use gears, chains, cable pulleys and other transmission parts to transmit power. The bucket, bucket door rib and lifting beam are the main components of the electric shovel. The Doumen includes a Doumen body and a Doumen tendon plate arranged on the outer side of the Doumen body, and the Doumen rib plate is a grid plate. The lock rod seat is fixed on the Doumen body and is used to install the lock rod. The installation position of the lock rod seat on the Doumen body corresponds to a grid hole of the Doumen rib. At present, the positioning of the lock rod seat in the bucket door body of the electri...
