As shown in FIG. 1, in one embodiment, a welding device 10 is provided that includes a mount 100, a welder body 200, a height adjustment mechanism 300, and a cooling element 400. Wherein, the welder body 200 is arranged on the mounting surface 110 of the mounting piece 100; the height adjusting mechanism 300 is in transmission connection with the mounting member 100 and is used for adjusting the height of the mounting member 100; the cooling element 400 is provided on the mount 100, and the cooling element 400 is used to cool the welding machine body 200.

When the welding device 10 of the embodiment is used, the welding machine body 200 is fixedly arranged on the mounting surface 110 of the mounting piece 100 in a welding, screwing, riveting, clamping and other modes, and the height of the mounting piece 100 is adjusted by the height adjusting mechanism 300, so that the height of the welding machine body 200 can be adjusted, and the welding machine body 200 can meet the welding requirements of different heights of steel gratings; and, utilize the air conditioning component can cool off welding machine body 200 among the welding process, guarantee that welding machine body 200's temperature is in normal temperature range for the weldment work of steel grating can adapt to comparatively confined tunnel environment, avoids welding machine body 200 high temperature and takes place to damage, guarantees that weldment work's normal, continuation goes on.

It should be noted that the mounting member 100 can be a mounting plate, a mounting table, or other structure that can provide a mounting and supporting location for the welder body 200. The welder body 200 can be any tool known to be capable of welding steel grids.

Wherein, height adjustment mechanism 300 adjusts the height of installed part 100, can realize through the mode of stretching out and drawing back (for example, the flexible installed part 100 that drives of the telescopic link through pneumatic cylinder or pneumatic cylinder rises or descends), also can realize through linear electric motor driven mode, can also realize through rotation drive's mode, only need satisfy can the installed part 100 highly carry out nimble regulation can.

As shown in fig. 1, in one embodiment, the height adjustment mechanism 300 includes a rotary driver 310, a lead screw 320 connected to a rotary output end of the rotary driver 310, and a guide 330 spaced opposite to the lead screw 320. The mounting member 100 is disposed on the screw rod 320 and is threadedly connected to the screw rod 320, and the mounting member 100 is guided by the guiding member 330. Thus, when the rotary output end of the rotary driving element 310 rotates, the screw rod 320 is driven to rotate around the central axis of the screw rod, and the threaded connection between the installation element 100 and the screw rod 320 and the guiding cooperation between the installation element 100 and the guiding element 330 are combined, so that the installation element 100 can reciprocate along the length direction (the direction a in fig. 1) of the screw rod 320, and further the welder body 200 can be driven to reciprocate along the length direction of the screw rod 320, and the height of the welder body 200 can be flexibly adjusted. The rotary drive 310 may be a servo motor or other element capable of providing a rotary drive torque in the forward and reverse directions.

In addition, the mounting member 100 is in threaded connection with the screw rod 320, and a threaded through hole can be directly formed in the mounting member 100, and the screw rod 320 is screwed into the threaded through hole; the screw connection can also be realized indirectly by means of an intermediate element.

The mounting member 100 has a mounting through hole (not shown), and the mounting sleeve 340 is fixed in the mounting through hole by means of adhesion, interference fit, or the like. And the internal threads can be threadedly engaged with the external threads of the lead screw 320. Therefore, the threaded connection between the mounting piece 100 and the screw rod 320 can be realized only by sleeving the mounting sleeve 340 on the screw rod 320, and the screw rod 320 can smoothly drive the mounting piece 100 to reciprocate along the length direction of the screw rod 320 when rotating.

One side of the mounting member 100 is provided with a protrusion (not shown) that extends into the guide groove. In this way, the protrusion moves along the guide groove to guide the reciprocating motion of the mounting member, and the side wall of the guide groove restricts the protrusion, so that the mounting member 100 cannot rotate around the central axis of the screw rod 320, thereby allowing the mounting member 100 to perform only reciprocating linear motion in the length direction of the screw rod 320.

Thus, the base 500 can be flexibly moved by the moving component 510, so that the whole welding device 10 can flexibly move according to actual welding requirements, welding requirements of the steel grating in the tunnel are met, and the use is flexible and convenient. Further, to facilitate the movement, a handle 332 may be provided on the guide 330 to assist the force to move. Wherein, the moving component 510 can be a moving pulley, a moving roller, a universal wheel or other components capable of assisting the base 500 to move.
