Abstract
The invention relates to a trackless submerged-arc automatic welding machine used for a super-large arc-shaped H-type steel member, comprising a submerged-arc automatic welding machine, wherein four traveling wheels are arranged on a machine head of the submerged-arc automatic welding machine; a supporting frame is respectively arranged on two sides of the machine head of the submerged-arc automatic welding machine; two supporting rods are arranged between the two supporting frames in a fore-and-after way; and supporting rollers are arranged on one side of the supporting frames adjacent to a workpiece. In the trackless submerged-arc automatic welding machine used for the super-large arc-shaped H-type steel member provided by the invention, adjustable threaded rods are adopted and are used for arranging the supporting rollers, so that the welding machine can perform welding along a circular-arc profile of a steel structural member during the traveling and welding processes, and an H-type steel structural member with a large circular arc can be obtained by only adopting the general process. The trackless submerged-arc automatic welding machine has the advantages of convenience for operation and simple structure.
Description
Technical field:
The present invention relates to metal solder, relate in particular to welding equipment, particularly a kind of trackless submerged arc automatic welding machine that is used for super large arc H Steel section member.
Background technology:
Submerged arc welding machine is the first-selected welding equipment that one of requisite main welding equipment during steel construction is made, particularly the H shaped steel of forming at big slab material obtain to generally acknowledge with the advantage technology of Lincoln weld especially.The member of present most of H shaped steel is straight lines, generally all can on box welding equipment, finish (being commonly called as gantry welding machine), if but the welding of the H shaped steel of forming by super large circular arc or semi arch or the big plectane of band camber, usual common box welding machine just can't be finished welding job, if reequip box welding machine, just have long in time limit, cost is high, the equipment of repacking such as also will change back later at many workload and very high production costs.
Summary of the invention:
The object of the present invention is to provide a kind of trackless submerged arc automatic welding machine that is used for super large arc H Steel section member, the described this trackless submerged arc automatic welding machine that is used for super large arc H Steel section member will solve the technical problem that the prior art welding machine does not weld the H Steel section member of the big plectane composition of arc.
This trackless submerged arc automatic welding machine that is used for super large arc H Steel section member of the present invention, constitute by submerged arc automatic welding machine, described submerged arc automatic welding machine includes head, tip, solder flux hopper, wire reel and power supply box, described head downside is provided with four insulation road wheels, wherein, described head both sides are respectively arranged with a bracing frame, be provided with two support bars between described two bracing frames, support bar is provided with support roller on the elongated end of workpiece direction, be provided with insulating sleeve between support bar and the bracing frame.
Further, support bar is made of adjustable threaded rod to the elongated end of workpiece direction.
Further, described support roller is provided with electrical insulation, makes electric insulation between support roller and the workpiece.
Operation principle of the present invention is: welded piece is selected suitable place, put into constant slope (fixed) by the workpiece concrete condition, submerged arc automatic welding machine is placed on the workpiece, rely on gravity to tilt to the riser of H Steel section member, support bar makes head and flange plate keep stable distance, support roller is walked on flange plate, in traveling process, welds along the arc profile of steel construction piece.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention is provided with bracing frame on submerged arc automatic welding machine, on bracing frame, connect and to regulate threaded rod, can regulate support roller is set on the threaded rod, support bar makes head and flange plate keep stable distance, support roller is walked on flange plate, and welding machine can be welded along the arc profile of steel construction piece in the welding process of advancing, and only needs to adopt common process just can realize having the H formed steel construction spare of great circle arc, easy to operate, simple in structure.
Description of drawings:
Fig. 1 is a kind of work schematic diagram that is used for the trackless submerged arc automatic welding machine of super large arc H Steel section member of the present invention.
Fig. 2 is the schematic diagram that workpiece tilts to put in the embodiments of the invention.
The specific embodiment:
Embodiment 1:
Show as Fig. 1 and Fig. 2, a kind of trackless submerged arc automatic welding machine that is used for super large arc H Steel section member of the present invention, constitute by submerged arc automatic welding machine, described submerged arc automatic welding machine head 1 is provided with four insulation road wheels 2, wherein, respectively be provided with a bracing frame 3 in described submerged arc automatic welding machine head 1 both sides, state is provided with two support bars 4 before and after being between described two bracing frames 3, and described bracing frame 3 is provided with support roller 6 near workpiece 5 welding positions one side.
Described support roller 6 is connected with described bracing frame 3 by adjustable threaded rod 7, and described adjustable threaded rod 7 and described bracing frame 3 are connected by screw thread.
Be arranged with insulating sleeve 8 on described support bar 4, described insulating sleeve 8 is between described support bar 4 and described bracing frame 3.
Electric insulation between described support roller 6 and the workpiece 5.
Concrete, welded piece 5 is selected suitable place, put into constant slope (fixed) by the workpiece concrete condition, as shown in Figure 2, falsework 9 needs assurance workpiece 5 to put safety, support is firm, and the welding head that needs to guarantee to be placed on the workpiece is not turned on one's side when work outward, needs to guarantee that power line 10 does not influence welding head and normally walks; This head road wheel must insulate well, and walking is normal, needs before the operation to check to guarantee insulation between welding head and the welded piece; Connect " ground strap " to welded piece; Start power supply box 13, connect power supply, instruct requirement with welding procedure in the usual way, can weld.In the welding process owing to contact between support roller and the super large girder steel circular arc flange plate 51, play the guiding role, therefore tip 11 can form the circular arc path along this flange plate 51, and then forms circular arc weld seam 12, and scolder arrives tip 10 by solder flux hopper 14 via solder flux material 15 pipes in the welding process.
