Description

Technical Field

[0001] The invention relates to the technical field of electric welding operations, and in particular to a portable welder operation vehicle device. Background Art

[0002] An AC welder is a device that uses alternating current for welding. Its working principle is based on electromagnetic induction. When the primary winding of the transformer is connected to an AC power source, an alternating magnetic field is generated in the iron core. This alternating magnetic field induces an electromotive force in the secondary winding, thereby generating the low voltage and high current required for welding. Since the direction of the AC current changes periodically, the polarity of the arc will also change periodically during the welding process, which is different from a DC welder.

[0003] There are many fire hazards in AC welding machine operation, such as high-temperature slag splashing, arc high temperature and electric spark generation. During the welding process, high-temperature slag can splash onto the surrounding flammable materials, the arc high temperature will generate heat radiation to the flammable items, and the electric spark may instantly ignite flammable gases, liquids or solid materials. At the same time, there are often a large number of flammable materials in the welding environment, whether it is chemicals and packaging materials in industrial sites, or wood and insulation materials in construction sites, they are all easily ignited by the dangerous factors generated by welding. Therefore, fire prevention of AC welding machines is extremely necessary, and effective measures must be taken to prevent the occurrence of fires and ensure the safety of operations and the surrounding environment.

DETAILED DESCRIPTION

[0021] Example, by Figure 1-5 The present invention includes symmetrically arranged side frames 1 and electric welding machines 100. The side frames 1 are square. A cross bar 2 and a cross plate 3 are fixedly connected above the two side frames 1. Reinforcement ribs can be added between the cross bar 2 and the side frames 1 to increase the stability of the device. A distribution box 4 is fixedly installed on the top of the cross plate 3. The distribution box 4 adopts a three-level distribution box, and the box includes an air switch and a leakage protector. The electric welding machine 100 is powered by the distribution box 4 for electric welding. The sides of the two side frames 1 are fixedly installed with mounting brackets 5. A fire extinguisher 6 is placed in the mounting bracket 5. The fire extinguisher 6 is a 5KG dry powder fire extinguisher to ensure that the fire source can be extinguished in time when a sudden fire occurs. A universal wheel 7 is fixedly installed at the bottom of the side frame 1 to increase the flexibility of the device. A lifting assembly 8 is movably installed between the two side frames 1; the electric welding machine 100 is lifted by two lifting assemblies 8. The electric welding machine 100 is moved together with the device.

[0022] A first slot 11 is provided above the crossbar 2, and a control handle 10 is inserted into the first slot 11;

[0023] The lifting assembly 8 includes a lifting plate 81 and a cantilever rod 82. Triangular mounting plates 811 are fixedly installed at both ends of the lifting plate 81. A fixed shaft 822 is fixedly installed on the side of the cantilever rod 82. One end of the fixed shaft 822 is rotatably installed on the side of the side frame 1. A connecting seat 821 is fixedly installed on one end of the cantilever rod 82. The connecting seat 821 is rotatably connected to the triangular mounting plate 811. A second slot 823 of the same size as the first slot 11 is opened at the other end of the cantilever rod 82.

[0024] In this embodiment, it is first necessary to move the device to the side of the electric welding machine 100, and then wrap the electric welding machine 100 through the moving device so that the rollers and the base of the electric welding machine 100 are located between the two lifting components 8, and then the lifting plate 81 is suspended at a certain angle by the cantilever rod 82, so that the electric welding machine 100 can be lifted. In addition, in order to increase the stability after lifting, the lifting component 8 and the rollers or base of the electric welding machine 100 can be squeezed against each other to increase the stability of the electric welding machine 100.

[0025] There are two first slots 11 on one crossbar 2, and two second slots 823 are provided in one lifting assembly 8. The center distance between the two first slots 11 is equal to the center distance between the two second slots 823. The control handle 10 is Y-shaped, and the front end of the control handle 10 matches both the first slot 11 and the second slot 823. A limiting protrusion 102 is fixedly installed on the control handle 10 to limit the depth of the front end of the control handle 10 inserted into the first slot 11 to avoid bending and deformation of the front end of the control handle 10 after being inserted too deeply. A handle bar (101) is fixedly installed at the tail of the control handle 10, and the middle part of the control handle 10 is bent.

[0026] In this embodiment, when the device needs to be moved, the control handle 10 cooperates with the first slot 11 to facilitate the movement of the control device. When the electric welder 100 needs to be lifted, the control handle 10 cooperates with the second slot 823 to increase the distance of the lever arm, and one side of the electric welder 100 can be easily lifted. Then, the control handle 10 cooperates with the second slot 823 on the other side to complete the lifting of the electric welder 100. After use, the control handle 10 is inserted into the first slot 11, which can facilitate the simultaneous movement of the work vehicle device and the electric welder 100.

[0027] Both sides of the top of the lifting plate 81 are provided with inclined surfaces for facilitating the passage of the electric welding machine 100 , and the top surface of the lifting plate 81 is provided with an anti-slip layer.

[0028] In this embodiment, the added inclined surface facilitates the passage of the electric welder 100. If necessary, one side of the electric welder 100 is lifted slightly. The stability of the electric welder 100 can be increased by providing an anti-slip layer.

[0029] A ratchet assembly 9 is fixedly installed at one end of the fixed shaft 822, and the ratchet assembly 9 includes a ratchet disk 91, a pawl 92 and a spring telescopic rod 93. The middle part of the ratchet disk 91 is fixedly sleeved on one end of the fixed shaft 822, the pawl 92 is rotatably installed on the side of the side frame 1, and the spring telescopic rod 93 is fixedly installed on the side of the side frame 1. One end of the output end of the spring telescopic rod 93 is in contact with the side of the pawl 92, and the pawl 92 is meshed with the tooth groove of the ratchet disk 91.

[0030] In this embodiment, the ratchet assembly 9 can limit the rotation of the cantilever rod 82 after the electric welding machine 100 is lifted to a certain position, and the lifting height of the electric welding machine 100 is easy to control.

[0031] Working principle: by adding mounting brackets 5 on both sides of the working vehicle device, fire extinguishers 6 can be placed to ensure that the fire extinguishers 6 can be used in time to extinguish the fire in case of a sudden fire. A distribution box 4 is added on the top of the working vehicle to facilitate power supply. Through the movable lifting component 8, electric welders 100 of different sizes can be lifted to a certain height, so that the electric welder 100 can move with the working vehicle device. Among them, the control handle 10 provided can not only serve as a handle to control the working vehicle device, but also as a lever arm of the cantilever rod 82, so that the lifting plate 81 can be lifted by using the control handle 10 in conjunction with the cantilever rod 82. It has a wide range of applications and is flexible to use.

[0032] Implementation steps:

[0033] 1) First, Figure 1 As shown, the work vehicle device is moved to the side of the electric welder 100, at which time the bottom of the lifting assembly 8 is close to the bottom surface, and then the work vehicle device is pushed so that the electric welder 100 enters the inner space of the work vehicle, and the rollers or base on one side of the electric welder 100 pass through the two lifting assemblies 8, and one side of the electric welder 100 is lifted if necessary;

[0034] 2) Then remove the control handle 10 from the first slot 11, and insert the front end of the control handle 10 into the second slot 823, as shown in FIG. Figure 2 As shown, the rear end of the control handle 10 is pressed downward to lift the lifting plate 81, thereby lifting the welding machine 100;

[0035] 3) Lift the other side of the welding machine 100 in the same way as in step 2, and try to control the lifting plate 81 to contact the base or roller of the welding machine 100 to increase stability;

[0036] 4) Then, take the control handle 10 out of the second slot 823 and insert it back into the first slot 11. At this time, the working vehicle device can be moved at will;

[0037] 5) Finally, the distribution box 4 is connected to the welding machine 100, and the welding machine 100 is set up to perform welding operations.
