Description

Technical Field

[0001] The utility model relates to the technical field of welding devices, in particular to a welding device for a special-shaped steel structure floor. Background Art

[0002] When installing special-shaped floor slabs such as corrugated plates and wedge-shaped plates, a welding machine is required for welding. The handheld welding machine is connected to the power supply by plugging in the power switch or connecting the power cord. Once the power is connected, the transformer in the welding machine converts direct current into high-voltage, low-current alternating current.

[0003] When a sufficient voltage difference is formed between the two electrodes, the electrons in the air will cross this distance to form an arc. The high temperature of the arc will quickly melt the welding wire at the bottom of the welding gun. Harmful gases will be produced in this process, which will harm the health of personnel. In addition, when welding special-shaped floor slabs, due to their large specifications and wide range, the welding machine equipment needs to be moved frequently, which is inconvenient to use. For this reason, we propose a special-shaped steel structure floor welding device to solve the existing problems. Utility Model Content

The pulley is rotatably installed inside the bearing through the second rotating shaft, and when providing rolling support for the upper end device, it can rotate horizontally to adjust the driving angle of the device.

[0008] Preferably, the lower end of the shear plate is rotatably sleeved on the outer wall of the installation shaft. When the shear plate is squeezed and pulled, the lower end rotates on the outer wall of the installation shaft and exerts a longitudinal force on the installation shaft.

[0009] Preferably, an exhaust port is provided at the upper end of the purification box, and the harmful gas generated by welding purified by the purification box is adsorbed by activated carbon.

The clamp block sleeves the suction pipe and the connecting wire at the handle together, and the suction hood always corresponds to the position of the welding gun, avoiding the worker frequently adjusting the position of the suction hood when adjusting the welding position.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model sets four pulleys at the bottom of the welding machine to provide sliding support for the bottom of the welding machine.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 4 As shown, a special-shaped steel structure floor welding device proposed by the utility model includes a welding machine 1, a motor 3, a purification box 4, a welding gun 9, a nut 14, a base 16 and a mounting seat 20. The welding machine 1 is provided with a base 16 at the lower end, and a symmetrically distributed motor 3 is provided at one end of the base 16. A screw 13 is provided at one end of the motor 3. Both ends of the screw 13 are rotatably installed inside the bottom frame 2. Two groups of symmetrically distributed nuts 14 are rotatably sleeved on the outer wall of the screw 13. The outer wall of the screw 13 is provided with two groups of relatively distributed threads. A slider is provided at the upper end of the nut 14, and the slider slides laterally. It is movably installed on the inner wall of the upper end of the bottom frame 2, and a base 16 is provided at the lower end of the nut 14. A symmetrically distributed mounting seat 20 is provided below the screw 13, and a pulley 15 is provided below the mounting seat 20. A rotating shaft 22 is provided on the upper end of the pulley 15. A bearing 21 is embedded and installed inside the lower end of the mounting seat 20, and the upper end of the rotating shaft 22 is rotatably inserted in the bearing 21. A mounting shaft 19 is inserted in the mounting seat 20, and a rotating shaft 18 is rotatably installed inside the base 16. The front and rear ends of the rotating shaft 18 are connected to shear plates 17, and the lower end of the shear plate 17 is rotatably sleeved on the outer wall of the mounting shaft 19.

[0023] Implementation steps based on Example 1: When welding special-shaped steel structure floor slabs, because the specifications of the floor slabs are large, the welding machine 1 needs to be frequently moved. It is more laborious to weld the joints of special-shaped steel structure floor slabs at different positions and to move the welding machine 1. At this time, the motor 3 is operated to drive the screw 13 to rotate. Because the threads on the outer wall of the screw 13 are relatively distributed in two groups, the nut 14 guided by the sliding is relatively pushed. The upper end of the shear plate 17 is connected to the rotating shaft 18, and the lower end is rotatably sleeved on the outer wall of the mounting shaft 19 fixed inside the mounting seat 20. The pulley 15 under the same screw 13 moves relatively with the nut 14. The pulley 15 contacts the ground and lifts the bottom frame 2 to support the bottom sliding of the welding machine 1. The pulley 15 can be rotated horizontally through the main shaft 2 to facilitate the adjustment of the orientation. After reaching the specified position, the screw 13 rotates in the opposite direction, and the pulley 15 is stored in the bottom frame 2. When the welding machine 1 moves, convenient movement is achieved. In the welding process of large-sized special-shaped steel structure floors, it is convenient to use during frequent movements.

[0024] like Figure 1-Figure 4 As shown, compared with the first embodiment, the special-shaped steel structure floor welding device proposed by the utility model further includes: a purification box 4 is arranged at the upper end of the welding machine 1, a fan 12 is arranged inside one end of the purification box 4, activated carbon is arranged inside the purification box 4, an exhaust port is opened at the upper end of the purification box 4, a connecting wire 6 is arranged at one end of the welding machine 1, a welding gun 9 is arranged at one end of the connecting wire 6, a handle 8 sleeved on the outside of the connecting wire 6 is arranged at one end of the welding gun 9, a suction hood 7 is arranged above the welding gun 9, a suction pipe 5 connected to the suction end of the fan 12 is arranged at one end of the suction hood 7, a card block 10 is sleeved on the outer wall of the suction pipe 5 and the connecting wire 6, and a filter screen 11 is arranged at the opening of the suction hood 7.

[0025] In this embodiment, the handle 8 is grasped and the connection of the special-shaped steel structure floor is welded by the welding gun 9. At this time, the fan 12 is in operation, and the suction force acts on the suction hood 7 through the suction pipe 5 to suck the harmful gas generated at the welding point. The harmful gas enters the purification box 4 and is purified by activated carbon adsorption to avoid direct adsorption in the body of the staff, thereby protecting the staff.
