Moving trolley for conveying main fixture on main welding line for automobile welding

Abstract

The invention relates to a moving trolley for conveying a main fixture on a main welding line for automobile welding. The moving trolley is provided with a moving trolley frame, and a hanger trolley track perpendicular to the running direction of the moving trolley is arranged at the bottom of the moving trolley frame; a connecting pipe is arranged on each of the left side and the right side of the moving trolley frame, and a set of hanger trolley limit opening and closing device is arranged on each of the front and the back of each connecting pipe; a set of hanger trolley drive device is alsoarranged on each of the left and the right at the bottom of the moving trolley frame and is used for driving a hanger trolley with the main fixture to run; and a detection frame is also arranged on one side of the moving trolley frame, a travel sensor is arranged on each of the front side and the back side of the detection frame, and a hanger trolley pneumatic locking mechanism is also arranged at the bottom of the moving trolley frame positioned on the same side as the detection frame. The moving trolley provided by the invention is safe and reasonable in structure design and accurate to position and can be better matched with the operation of whole main fixture conveying equipment, thereby having good practical use and promotion values.

Description

technical field [0001] The invention relates to the technical field of automobile welding auxiliary equipment, in particular to a traveling trolley used for conveying main fixtures of main welding wires for automobile welding. Background technique [0002] In the automobile production workshop, the main fixture of the body welding main welding line is usually loaded and transported by a spreader trolley. Due to the heavy weight of the main fixture itself and the weight of the spreader trolley, the transport of the fixture must be carried out by means of a shifting It can only be completed by a trolley. The traditional mobile trolley has limitations in terms of drive system and safety measures, low positioning accuracy, and inadequate protection measures, posing safety hazards. Contents of the invention [0003] The purpose of the present invention is to provide a novel and compact structural design, precise positioning, and accurate safety limit for the main welding wire m...
