Abstract
The invention provides a method for forming and assembling four faces of a bridge crane box type girder. A locating jig frame for adjusting camber by using a screw rod is arranged on the bottom surface of the girder, and corresponding push rods are arranged on the other three faces for locating and uses a worm mechanism so as to achieve back-and-forth telescoping. The method is suitable for multiple girder assembly. The running mode of a machine mechanism is simple, operation is convenient and reliable, assembly efficiency is high, and simultaneously torsion resistance and straightness of the girder and web plate verticality can be controlled well in the manufacturing process.
Description
Technical field
The present invention relates to a kind of crane mechanism manufacturing approach, be specifically related to a kind of bridge crane box girder four sides moulding assemble method.
Background technology
Existing bridge crane box girder moulding on four sides assembling is main with craft mainly, still can not accurately control owing to manual operations, thereby for the manufacturing of workshop production in enormous quantities nowadays very big restriction arranged, and not too adapts to existing production demand.In the process that girder is manufactured now, mainly there is following several respects shortcoming in hand assembled:
1. make efficiency is very low;
2. package size is difficult to hold;
3. the girder manufacturing technology requires to be difficult to control, like linearity, torsion resistance, the web perpendicularity of girder.
Summary of the invention
The object of the invention is to provide a kind of bridge crane box girder four sides moulding assemble method, and it adopts four sides positioning principle simultaneously, can improve the inconvenience that hand assembled is brought greatly; Improve box girder type position tolerance grade; Improve make efficiency, practice thrift cost of labor, saves energy consumption.
In order to solve these problems of the prior art, technical scheme provided by the invention is:
A kind of bridge crane box girder four sides moulding assemble method; At first adjust the camber of kludge moulding bed, the girder upper cover plate is positioned on the kludge moulding bed of adjusting, then girder is fixed on the girder upper cover plate; At the both sides of girder installing diaphragm plate; Lift the web of both sides then, two blocks of webs are held out against on diaphragm plate, web is navigated to upper cover plate and diaphragm plate from box house spot welding through electronic depression bar; Through electric pushrod lower cover is pressed on the girder again, adopts electric welding location welding lower cover and web simultaneously.
Detailed technical scheme is: a kind of bridge crane box girder four sides moulding assemble method, at first adjust the camber of kludge moulding bed, and the girder upper cover plate is positioned on the kludge moulding bed of adjusting; Then girder is fixed on the girder upper cover plate,, lifts the web of both sides then at the both sides of girder installing diaphragm plate; Through electronic depression bar two blocks of webs are held out against on diaphragm plate, web is navigated to upper cover plate and diaphragm plate, through electric pushrod lower cover is pressed on the girder again from box house spot welding; Adopt electric welding location welding lower cover and web simultaneously, also be provided with a moving beam in the assemble method, moving beam is used for moving the position of girder; The moving beam top is provided with electric pushrod; Electric pushrod is used to adjust the working depth of moving beam, and electric pushrod can move along girder, and the position that is used to adjust electric pushrod is to adapt to the girder of differing heights; The kludge moulding bed is provided with screw rod, and screw rod is used to adjust the camber of moulding bed.
With respect to scheme of the prior art, advantage of the present invention is:
The present invention adopts four sides overall package moulding process, the location moulding bed of the useful screw rod adjustment in bottom surface camber, and other three face all has corresponding push rod location; Push rod uses worm mechanism, thereby can realize elasticly, is applicable to multiple beam type assembling; This machine mechanism method of operation is simple; Convenient and reliable operation, packaging efficiency is high, can well control torsion resistance, linearity and web perpendicularity that girder is made simultaneously.
