Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding device, in particular to a welding device for tunnel construction. BACKGROUND

[0002] In the process of tunnel construction, the tunnel needs to bear the ground pressure, water pressure and seismic force, so it is necessary to increase the reinforced concrete structure inside it. The reinforced concrete has strong integrity, can uniformly transmit load, effectively resist ground deformation and sudden impact, and the concrete wrapping the reinforcement forms a protective layer to prevent groundwater from corroding the reinforcement, and cooperates with PE anti-seepage plate and other materials to build a multiple anti-seepage system. At the same time, the cast-in-place reinforced concrete forms a rigid structure, the node connection is firm, the seismic performance is superior, and the strength of the tunnel can be effectively strengthened.

[0003] When pouring reinforced concrete in the tunnel, the reinforcement needs to be welded by the electric welding machine. During welding, the electric welding machine moves with the pulling of the construction personnel. Since the tunnel is a construction site, it cannot guarantee the full cleanliness inside the tunnel, so the electric welding machine is easily blocked by the rubble when moving. If it is pulled forcibly, it is easy to cause the electric welding machine to overturn, and if a larger stone is encountered, the electric welding machine will be damaged if the construction personnel pull the electric welding machine forcibly, causing the electric welding machine to collide with the stone. Moreover, once the stone collapses in the tunnel, the larger stone will also cause damage to the electric welding machine when it hits the electric welding machine. SUMMARY

[0067] In summary, the working principle of the welding device for tunnel construction provided by the embodiment of the present application is as follows:

[0068] When welding, the worker pulls the welding machine box 1 through the welding cable 3 to move, so that the welding machine box 1 drives the traveling base plate 4 to move, and the traveling base plate 4 drives the four escape carriages 601 to move, and then the escape carriages 601 move through the traveling rollers 5. It should be noted that when the two traveling rollers 5 in front encounter an obstacle, the front baffle 608 is extruded and compressed, the front baffle 608 is limited to move on the escape carriage 601 through the limiting slide rod 609, and the reset spring 610 is stressed, the front baffle 608 moves to drive the connecting slide rod 612 to move, so that the connecting slide rod 612 drives the extrusion push bar 606 to move, the extrusion push bar 606 slides on the bottom side of the traveling base plate 4, and the extrusion push bar 606 moves to drive the two extrusion push shafts 607 to move, so that the extrusion push shafts 607 drive the V-shaped swing lever 604 to rotate, the V-shaped swing lever 604 rotates on a swing connecting shaft 605, and the V-shaped swing lever 604 drives the linkage sliding plate 602 to move through the other swing connecting shaft 605, the linkage sliding plate 602 drives the two escape carriages 601 to move, the escape carriages 601 slide in the expansion sliding groove 613, and the contraction spring 614 is stressed, so that the escape carriages 601 avoid the obstacle, and at this time, when the welding machine box 1 continues to move, the obstacle can be automatically avoided and moved;

[0069] Further, when the welding machine box 1 advances, if a large rock falls, the detection carriage 701 first contacts the rock and is extruded by the rock, so that the detection carriage 701 slides in the sliding groove 702 and the pull-back spring 703 is stressed, and when the detection carriage 701 moves, the four adapter supports 707 are driven to move, so that the adapter supports 707 drive the locking adapter rod 708 to rotate through the adapter shaft 709, the locking adapter rod 708 rotates to drive the locking down frame 704 to move through the sliding shaft 710, so that the locking down frame 704 drives the locking tooth plate 705 to move, and then the welding machine box 1 is clamped on the ground, so that the welding machine box 1 stops advancing, avoiding the problem that the welding machine box 1 is damaged due to collision with the rock;

[0070] Further, when the collapse of the stone occurs in the tunnel, the stone falls on the falling impact plate 803, so that the plurality of falling impact rods 802 moves in the plurality of impact sheaths 801, and the plurality of impact springs 804 is forced, and then under the rebound force of the plurality of impact springs 804, the falling impact plate 803 rebounds the smaller stone, for protecting the electric welding machine box 1; in addition, if the stone is too large, so that the falling impact rod 802 moves down synchronously drives the L-shaped drive frame 813 to move, the L-shaped drive frame 813 extrudes the rotating separation push rod 808 to rotate, the rotating separation push rod 808 rotates in the installation groove 811 through a separation rotating shaft 809, and the recovery torsion spring 812 is forced, at the same time, the rotating separation push rod 808 drives the separation drive frame 807 to move through another separation rotating shaft 809, and then the separation drive frame 807 drives the separation sliding plate 806 to slide in the separation sliding groove 805, so that the separation sliding plate 806 drives the electric welding machine box 1 to separate from the accompanying bottom plate 4, thereby effectively avoiding the problem that the large stone falling damages the electric welding machine box 1; in addition, it should be noted that the two falling impact rods 802 move down to drive the two L-shaped extrusion frames 814 to move, so that the two L-shaped extrusion frames 814 extrude the wedge-shaped seat 815 to move, so that the wedge-shaped seat 815 drives the detection sliding frame 701, and then the accompanying bottom plate 4 can also be clamped on the ground, avoiding the problem that the continuously collapsed stone on the forward path of the electric welding machine box 1 causes the damage of the electric welding machine box 1.

[0071] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
