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

The side board of carriage of dump truck hold down gag
Technical field
The present invention relates to welding technology field, especially a kind of device for the self-discharging carriage side plate is welded.
Background technology
Side board of railroad car is one of vitals of body of tipper carriage, the side board of railroad car that a kind of dumper is arranged, it is mainly by the upper and lower frame of forward and backward large column, side plate of side plate base plate, " U " shape, and the plank frame spare that consists of of the weld parts such as the side plate central post of respective numbers and middle horizontal bar.At present, the process of this side board of railroad car welding is that the parts that will form side board of railroad car weld successively on the platform of several welding posts and weld, and is connected with the platform that conveying parts is used between each welding post; The frame of this platform is hinged with a plurality of cranes by hinge, and the end that each described crane is located on the described platform table top all is equipped with cylinder, and the other end of each described crane is hinged with and drives described cylinder around the elevating ram of the described hinge anglec of rotation.The welding step of side board of railroad car is: on the table top of the first welding post platform the parts that form side board of railroad car were welded before this, then will weld on the side board of railroad car of getting well moves to the second welding post platform by platform the table top it is welded.There is following deficiency in process of production in the process of this side board of railroad car welding: the parts that 1, form side board of railroad car weld under free state fully, and bending deformation quantity is large; 2, welding deformation can not get control, and distortion mainly is the distortion along the side board of railroad car thickness direction, directly affects side board of railroad car flatness and presentation quality.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of side board of carriage of dump truck hold down gag, and this side board of carriage of dump truck hold down gag can solve the large problem of existing side board of railroad car bending deformation quantity.
The technical scheme that technical solution problem of the present invention adopts is: this side board of carriage of dump truck hold down gag comprises the frame that is provided with platform, the both sides of described frame are provided with track, described track is equipped with a plurality of portal frames by the walking wheel carrier, described portal frame top is provided with clamping cylinder, described clamping cylinder is contained on the slide rail at described portal frame top by the roller of its bottom, and described clamping cylinder is connected with the briquetting of lifting on guide pillar.
In the technical scheme of above-mentioned side board of carriage of dump truck hold down gag, technical scheme can also be more specifically: the middle part of described platform table top is provided with movable cushion block.
Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect: put to the table top of platform on the limit, compartment that 1, will finish a weld seam welding, makes side board of railroad car another side weld seam to be welded up; Side board of railroad car middle part is placed on the movable cushion block of platform, the side board of railroad car two ends just with the table top generation gap of platform; Adjust briquetting to the compression position at side board of railroad car two ends by the mobile gantry frame this moment, starts clamping cylinder, and side board of railroad car produces arc-shaped deformation under the effect of briquetting; This has executed a welding anti-distortion amount namely for side board of railroad car in advance, the two ends of side board of railroad car butt welded seam under impaction state welds, the deflection that side board of railroad car welds in welding process offsets with the welding anti-distortion amount that applies in advance, the bending deformation quantity of parts welding is little, thereby has reduced the welding deformation of side board of railroad car through-thickness.
2, by adjusting the differing heights of movable cushion block, can be fit to the anti-deformation requirement of the side board of railroad car of different length.
