Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

[0013] Such as figure 1 , figure 2 The shown dump car side plate pressing device includes a platform, and the frame 1 of the platform is hinged with a plurality of lifting frames 1-1 through hinge shafts 1-2, and each lifting frame 1-1 extends to one end of the platform table. Drum 1-4 is housed, and the other end of each lifting frame 1-1 is connected and is hinged with the lift oil cylinder 1-3 that drives drum 1-4 to rotate angle around hinge shaft 1-2 through intermediate parts. The two sides of frame 1 are equipped with rails 2, which are made of channel steel and fixed on the upper part of both sides of frame 1 by welding; The bottom of the bottom is connected with two walking wheels 9 by the wheel shaft, and the gantry is supported on the track 2 by the walking wheels 9 mounted on the moving plates on both sides; the track 2 upper frame of the...

Abstract

The invention discloses a compressing device for a carriage side plate of a self-dumper, which relates to the technical field of welding. The compressing device comprises a frame which is provided with a platform, wherein both sides of the frame are provided with tracks; a plurality of gantries are erected on the tracks through walking wheels; and compressing air cylinders are arranged above the gantries, are arranged on slide rails on the tops of the gantries through rollers at the bottoms of the compressing air cylinders, and are connected with pressure blocks ascending and descending on guide pillars. Compared with the prior art, the compressing device has the advantages that a welding counter-deflection is pre-applied to the carriage side plate, the two ends of the carriage side plate are used for welding a welding seam in a compression state, the welding deflection of the carriage side plate in a welding process counteracts with the pre-applied anti-deflection, and the welding bending deflections of parts are small, so that the welding deflection of the carriage side plate along a thickness direction is reduced.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a device for welding side plates of dump trucks. Background technique [0002] The side plate of the car is one of the important parts of the dump truck. There is a side plate of the dump truck, which is mainly composed of the bottom plate of the side plate, the "U" shaped front and rear columns, the side plate, the lower frame, and the corresponding quantity It is a plate structure composed of welding parts such as side plates, middle columns and middle transverse ribs. At present, the welding process of this kind of carriage side panel is to carry out tailor welding and welding of the parts that make up the side panel of the carriage on the platforms of several welding stations in sequence, and a platform for conveying parts is connected between each welding station The frame of the platform is hinged with a plurality of lifting frames through a hinge shaft, and each of the l...
