Carrier vehicle frame and mounting method thereof

Abstract

The invention provides a carrier vehicle frame and a mounting method thereof. The carrier vehicle frame comprises a middle frame and two carrier assemblies fixed to the two ends of the middle frame correspondingly. The middle frame comprises a chassis, a middle beam assembly and four clamping arm supporting shafts; the middle beam assembly is defined by two first longitudinal beams and two first cross beams, and the two first longitudinal beams and the two first cross beams are positioned and welded through a plurality of positioning pins; each carrier assembly comprises an end beam assembly,a driving device and a traveling device; and each end beam assembly comprises a second longitudinal beam, a second crossbeam and two bearing mounting beams, wherein the second longitudinal beam and the chassis, the second longitudinal beam and the second crossbeam as well as the two bearing mounting beams and the second cross beam are positioned and welded through the multiple positioning pins correspondingly. According to the carrier vehicle frame, the mode that positioning through the positioning pins and welding fixing are matched, so that all assembling parts are positioned more accurately, assembling and welding are facilitated, and the strength of the vehicle frame is improved; and through the mounting method, a mounting technique of the vehicle frame is simplified, the mounting timeis shortened, and the mounting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical parking equipment, in particular to a carrier frame and an installation method thereof. Background technique [0002] With the rapid development of the economy, the number of cars in each city is increasing, and the problem of parking difficulties is becoming more and more prominent. Therefore various mechanical three-dimensional parking garages arise at the historic moment. At this stage, the handling AGV frame used in the domestic mechanical three-dimensional garage has the following problems: (1) When the load is heavy, especially when the load exceeds 2.3 tons, the frame is prone to deformation, resulting in increased contact stress between the clamp arm and the guide rail , so that the outer rubber coating of the clamp arm cylinder cracks; (2) the positioning of the parts is inconvenient when the frame is welded, and the thermal stress during welding can easily lead to structural deformat...
