Abstract
The present invention relates to a kind of tyre crane portal frame welding method, need to be welded on saddle beam 4 supporting legs, every supporting leg needs to weld and is intended to welding inside and outside 4 limits, and each edge；Described method includes, detector gap, if excessive, outside patch ceramic substrate；Positioning welding, length 50mm；Formal welding, 4 supporting legs divide 4 people to weld simultaneously, concretely comprise the following steps: welding edge (a) and (b), (c), (d) outside successively, inside welding each edge, the most constant；The when of welding, each edge is all by welded clockwise.It is an advantage of the current invention that: in tyre crane portal frame welding method of the present invention, 4 welders weld 4 supporting legs simultaneously, and when adjacent supporting leg welds, the limit of welding is the most symmetrical, and this rational welding sequence prevents the generation of deformation.
Description
Technical field
The present invention relates to crane field, be specifically related to a kind of tyre crane portal frame welding method.
Background technology
Along with the growth of China's ports container quantity, the raising requiring the efficiency of loading and unloading, economic benefit, and the development of modern science and technology, tyre crane starts to play the part of the most important role.
Tyre crane portal frame is positioned at top by two and constitutes for the crossbeam of trolley travelling, four the support supporting legs of crossbeam, the saddle beams of bottom fixed supporting leg, is fixedly connected by welding between saddle beam and supporting leg；In general, tyre crane height and span are all at tens of rice, and deadweight is bigger；As a example by a 40T rubbertyred container gantry crane, maximum height that this crane hanger is liftoff is 18.20m, big beam span 23.47m；After supporting leg has welded with saddle beam, being conducted oneself with dignity by portal frame, the cause influence such as welding residual stress, portal frame may produce relatively large deviation and deformation.
Therefore, a kind of reasonably welding procedure operation of research and development is still important.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of tyre crane portal frame welding method, prevents portal frame from deforming.
For solving above-mentioned technical problem, the technical scheme is that a kind of tyre crane portal frame welding method, its innovative point is:
When saddle beam and supporting leg erection welding, gap is within 0 ~ 5mm, if excesssive gap, welds after the patch ceramic substrate of outside；
During welding, four supporting legs are divided into four people to carry out welding simultaneously, overlook direction with long axis direction as X-axis, short-axis direction is that Y-axis sets up rectangular coordinate system, the supporting leg number consecutively being positioned at this coordinate system first, second, third and fourth quadrant is supporting leg a, supporting leg b, supporting leg c, supporting leg d, the welding personnel number consecutively of corresponding supporting leg is welder a, welder b, welder c, welder d, all supporting legs are all having 4 to need the limits welded with saddle beam contact position, and inside and outside each edge all has；First welding the outside of each edge, concrete welding sequence is as follows:
Step a, welder a and welder d welding is each responsible for the limit away from X-axis of supporting leg, and welder b and welder c welding is each responsible for the limit of the close X-axis of supporting leg；
Step b, welder a and welder d welding is each responsible for the limit of the close X-axis of supporting leg, and welder b and welder c welding is each responsible for the limit away from X-axis of supporting leg；
Step c, welder a and welder b welding is each responsible for the limit away from Y-axis of supporting leg, and welder c and welder d welding is each responsible for the limit of the close Y-axis of supporting leg；
Step d, welder a and welder b welding is each responsible for the limit of the close Y-axis of supporting leg, and welder c and welder d welding is each responsible for the limit away from Y-axis of supporting leg；
After the outside of each edge being soldered each supporting leg, continuing inside welding, concrete welding sequence is constant.
Further, during welding, each edge is welded the most in a clockwise direction.
Further, tack welding, weld length 50mm are carried out before formal welding.
It is an advantage of the current invention that: in tyre crane portal frame welding method the most of the present invention, 4 welders weld 4 supporting legs simultaneously, and when adjacent supporting leg welds, the limit of welding is the most symmetrical, and this rational welding sequence prevents the generation of deformation；2. ensure the size of supporting leg and saddle beam gap before welding, interpolation ceramic substrate bigger than normal is welded, more accurately.
Accompanying drawing explanation
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the welding sequence schematic diagram of tyre crane portal frame welding method of the present invention.
Detailed description of the invention
The invention discloses a kind of tyre crane portal frame welding method, as it is shown in figure 1, portal frame includes two crossbeams 1 for trolley travelling being positioned at top, support four supporting legs 2 of crossbeam 1, and be positioned at the saddle beam 3 of the fixed supporting leg 2 of bottom；Needing during welding to be welded on saddle beam 3 four supporting legs 2, every supporting leg 2 contacts with saddle beam 3 all four limits, and each limit is required to inside and outside welding.
When saddle beam 3 and supporting leg 2 erection welding, gap is within 0 ~ 5mm, if excesssive gap, welds after the patch ceramic substrate of outside；Tack welding, weld length 50mm is carried out before formal welding.
During welding, four supporting legs are divided into four personal responsibilities, overlook direction with long axis direction as X-axis, short-axis direction is that Y-axis sets up rectangular coordinate system, the supporting leg number consecutively being positioned at this coordinate system first, second, third and fourth quadrant is supporting leg a, supporting leg b, supporting leg c, supporting leg d, the welding personnel number consecutively of corresponding supporting leg is welder a, welder b, welder c, welder d, all supporting legs are all having 4 to need the limits welded with saddle beam contact position, and inside and outside each edge all has；First welding the outside of each edge, as it is shown in figure 1, each edge is welded the most in a clockwise direction during every supporting leg welding, concrete welding sequence is as follows:
The first step, welder a and welder d welding is each responsible for the limit away from X-axis of supporting leg, and welder b and welder c welding is each responsible for the limit of the close X-axis of supporting leg；
Second step, welder a and welder d welding is each responsible for the limit of the close X-axis of supporting leg, and welder b and welder c welding is each responsible for the limit away from X-axis of supporting leg；
3rd step, welder a and welder b welding is each responsible for the limit away from Y-axis of supporting leg, and welder c and welder d welding is each responsible for the limit of the close Y-axis of supporting leg；
4th step, welder a and welder b welding is each responsible for the limit of the close Y-axis of supporting leg, and welder c and welder d welding is each responsible for the limit away from Y-axis of supporting leg；
After the outside of each edge being soldered each supporting leg, continuing inside welding, concrete welding sequence is constant.
Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; the principle that the present invention is simply described described in above-described embodiment and description; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within scope of the claimed invention.Claimed scope is defined by appending claims and equivalent thereof.
