Description

Technical Field

[0001] The invention relates to the field of electric welding, in particular to an electric welding machine capable of reducing smoke and dust. Background Art

[0002] When welding some outdoor support columns, a large amount of welding smoke will be generated, and there are many large particles of impurities in the welding smoke, which will cause damage to the body when people inhale these welding smoke. In the prior art, there is generally a method of absorbing the welding smoke to prevent people from inhaling the welding smoke, thereby protecting people's health. However, since the welding of the support columns is located outdoors, it is inevitable that there will be windy weather outdoors, and the wind will blow the welding smoke away, resulting in the inability to absorb the welding smoke, so that the welding smoke is inhaled by people after it floats away, thereby affecting the human body. Summary of the invention

[0003] In order to overcome the disadvantage that when welding some outdoor support columns, the wind will blow the welding smoke away, resulting in the welding smoke being unable to be absorbed, the present invention provides an electric welding machine that can reduce smoke.

[0004] The technical solution is: an electric welding machine capable of reducing smoke and dust, comprising a fixed ring, a slide rail, and a slider; the fixed ring is detachably connected to another fixed ring; all the fixed rings are fixedly connected to a slide rail, and all the slide rails are combined into a circular track; the circular track formed by all the slide rails is slidably connected to a plurality of sliders; and also comprises a wind shield; all the sliders are fixedly connected to a wind shield, and the wind shield is provided with a first air inlet, and the first air inlet is provided with a plurality of air suction ports, and a wind direction measuring device is provided on the upper part of the middle wind shield to block the wind through the wind shield.

[0005] As an improvement of the above solution, the two fixing rings are rotatably connected.

[0006] As an improvement of the above scheme, it also includes an air blowing plate, all wind shields are fixedly connected to an air blowing plate, and the air blowing plate is provided with a second air inlet, and the air blowing plate is provided with an air blowing port.

[0007] As an improvement of the above solution, the second air inlet located above the adjacent wind shield is configured as an inclined hole inclined toward the lower side of the center of the wind shield.

[0008] As an improvement of the above solution, a filtering device is also included, and all wind shields are connected to the filtering device.

[0009] As an improvement of the above solution, the filtering device is configured as a sponge.

[0010] As an improvement of the above solution, the left and right blowing plates are L-shaped, and the vertical parts are also provided with blowing ports.

[0011] As an improvement of the above scheme, it also includes a fixed plate, a spring telescopic rod, and a filter; the left and right windshield plates are fixedly connected to a fixed plate; all the fixed plates are fixedly connected to a plurality of spring telescopic rods; all the spring telescopic rods on the same fixed plate are fixedly connected to a filter, and the middle windshield plate is fixedly connected to another filter.

[0013] As an improvement of the above scheme, a cleaning plate is also included. The left filter is fixedly connected to the cleaning plate, and the cleaning plate is provided with a plurality of bristles.

[0014] Beneficial effect: The present invention prevents the wind from affecting the welding smoke generated by welding by rotating the wind shield to the windward direction and allowing the worker to weld in the leeward direction. When the worker moves to the windward direction, the wind shield contacts both sides of the worker after being unfolded, thereby preventing the wind from affecting the welding smoke generated by welding from both sides of the worker.

[0015] The present invention uses the air blowing plate to blow air downwards, so that the welding smoke cannot float upwards to the top of the wind shield, thereby not affecting the workers from above the wind shield; and the air blowing plate blows air toward the welded column, so that the welding smoke cannot float in the direction of the workers, thereby making the overflowing welding smoke unable to affect the workers.

[0016] The present invention filters out large particle impurities in the welding smoke sucked into the wind shield through the sponge block, so that the air blown out by the blowing plate does not contain substances harmful to human beings, and the sparks generated by welding can be quickly cooled by soaking the sponge block with water, and the sparks cannot rebound to the welded column, thereby protecting the welded column from being affected by the sparks.

[0017] The present invention prevents sparks from contacting the sponge block over a large area through the filter screen, prevents metal debris from being tightly attached to the sponge block, and cleans the metal debris through the shaking of the filter screen and the cleaning plate.

DETAILED DESCRIPTION

[0024] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments. Example 1

[0025] An electric welding machine capable of reducing smoke and dust, such as Figure 1-2 , including a fixed ring 1, a slide rail 2, and a slider 3; the fixed ring 1 is detachably connected to another fixed ring 1; all the fixed rings 1 are bolted to a slide rail 2, and all the slide rails 2 are combined into a circular track; the circular track formed by all the slide rails 2 is slidably connected to three sliders 3;

[0026] It also includes a wind shield 4; all sliders 3 are fixedly connected to a wind shield 4, and the wind shield 4 is provided with a first air inlet 4a, and the first air inlet 4a is provided with a plurality of air suction ports 4b, and a wind direction measuring device is provided on the upper part of the middle wind shield 4, and the wind is blocked by the wind shield 4, thereby preventing the wind from affecting the welding smoke.

[0027] The two fixing rings 1 are rotatably connected, so that the two fixing rings 1 can be folded up, thereby facilitating manual carrying.

[0028] The working steps of the above embodiment are: first, the two fixing rings 1 of the present invention need to be folded manually to form a Figure 2The state shown is carried by the present invention to move to the position of the column to be welded, and then the two fixing rings 1 are opened manually, and the present invention is put on the column to be welded, and then the present invention is placed on the ground, and then the wind direction is measured by the wind direction measuring device on the wind shield 4, and then all the wind shields 4 are driven to rotate to the windward direction through the slider 3, and then the manual operation is moved to the leeward direction, and then welding is started. Since the wind shield 4 is located in the windward direction at this time, the wind cannot blow to the welding position, so that the welding smoke generated by welding cannot be affected. Then, the air pump connected to the first air inlet 4a is used to inhale air, and then the air is inhaled through the air inlet 4b, and then the welding smoke generated by welding is sucked away through the air inlet 4b, so that the manual operation does not inhale the welding smoke. It should be noted that since the wind shield 4 is located in the windward direction at this time, the three wind shields 4 do not need to be fully unfolded, thereby providing sufficient operating space for the manual operation;

[0029] Since the welded column needs to be welded manually for a circle, the welding time is relatively long, and the wind direction will change during the welding process. Therefore, when the wind direction measuring device on the wind shield 4 detects that the wind direction has changed, the wind shield 4 is driven to rotate through the slider 3, so that the wind shield 4 is always located at a position relative to the wind direction, so that the wind shield 4 can always block the wind;

[0030] Since the manual labor needs to weld a circle of the welded column, the manual labor needs to move closer to the windward direction, so the wind shield 4 needs to rotate with the manual labor, which makes it impossible for the wind shield 4 to always be in the windward direction, resulting in the wind shield 4 being unable to completely block the wind. Therefore, when the central angle between the manual labor and the windward direction is less than ninety degrees, the manual labor is in contact with the wind shield 4 at this time, and then the wind shield 4 farthest from the manual labor is driven by the slider 3 to rotate to the side where the manual labor is not in contact with the wind shield 4 and contact the manual labor, thereby blocking the wind from the left or right side of the manual labor. The welding smoke generated by welding will then gradually move towards the leeward direction after passing through the windward direction. During the moving-together process, the wind shield 4 that is not in the path of manual movement will no longer continue to rotate after rotating to the windward direction, so as to no longer contact the manual work, thereby leaving a larger operating space for the manual work. When the manual work moves back to the leeward direction, the manual work completes the welding, and then the three wind shields 4 are rotated to the retracted state through the slider 3 again, and then the two fixing rings 1 are manually disassembled and separated, thereby removing the present invention from the welded column to complete the welding. Example 2

[0031] On the basis of Example 1, Figure 3-4As shown, a blowing plate 111 is also included, and all wind shields 4 are fixedly connected with a blowing plate 111, and the blowing plate 111 is provided with a second air inlet 111a, and the blowing plate 111 is provided with a blowing port 111b, and the blowing port 111b of the blowing plate 111 is used to prevent welding smoke from floating above the wind shield 4.

[0032] The second air inlet 111a located above the adjacent windshield 4 is configured as an inclined hole inclined toward the lower side of the center of the windshield 4, so that the airflow blown out of the air outlet 111b is inclined downward, thereby achieving a better effect of blocking welding smoke from floating upward.

[0033] It also includes a filtering device, and all windshields 4 are connected to the filtering device. Large particles in the welding smoke are filtered out through the sponge block 104, so that there are no substances harmful to the human body in the air blown out of the blowing port 111b, so that people will not be affected by inhalation.

[0034] The filtering device is configured as a sponge, which can absorb water through the sponge, so that sparks generated by welding can be quickly cooled and the sparks will not rebound onto the welded column.

[0035] The left and right air blowing plates 111 are L-shaped, and the vertical parts are also provided with air blowing ports 111b, thereby preventing welding smoke from floating toward people along the welded column.

[0036] The working steps of the above embodiment are: since the welding smoke generated by welding will float upward, part of the welding smoke will float upward to the top of the windshield 4 and be blown toward the manual direction by the wind, causing the manual inhalation of the welding smoke. Therefore, before welding, the other end of the air pump connected to the first air inlet 4a is manually connected to the second air inlet 111a, and the sponge block 104 is dipped in water, so that during welding, the air sucked in by the air inlet 4b can be blown downward through the air blowing port 111b, thereby preventing the welding smoke from floating above the windshield 4;

[0037] The large particles of impurities in the welding smoke sucked in by the air intake port 4b are filtered out by the sponge block 104, so that the air blown out from the air outlet 111b no longer contains substances harmful to the human body. The sponge block 104 soaked in water prevents sparks generated by welding from damaging the wind shield 4, and the sparks can be cooled immediately, and the sparks will not bounce back to the welded column after colliding with the sponge, so that the welding sparks will not affect the welding. Example 3

[0038] On the basis of Example 2, Figure 3 and Figure 5As shown, it also includes a fixed plate 101, a spring telescopic rod 102, and a filter 103; the left and right windshield plates 4 are fixedly connected to a fixed plate 101; all the fixed plates 101 are fixedly connected to four spring telescopic rods 102; all the spring telescopic rods 102 on the same fixed plate 101 are fixedly connected to a filter 103, and the middle windshield plate 4 is fixedly connected to another filter 103. The filter 103 prevents sparks from contacting the sponge block 104 over a large area, so that metal debris will not stick too tightly to the sponge block 104.

[0039] It also includes a protrusion 201 and an extrusion block 202; ten protrusions 201 are arranged at the lower part of all the filters 103; the middle wind shield 4 is fixedly connected to two extrusion blocks 202 distributed on the left and right, and the protrusion 201 and the extrusion block 202 cooperate with each other, and then the extrusion block 202 squeezes the protrusion 201, so that the filter 103 shakes up and down, and then the metal debris is cleaned.

[0040] A cleaning plate 203 is also included. The left filter screen 103 is fixedly connected to the cleaning plate 203 , and the cleaning plate 203 is provided with a plurality of bristles. The cleaning plate 203 is used to clean the metal debris on the middle sponge block 104 .

[0041] The working steps of the above embodiment are as follows: since sparks are generated during welding, and these sparks are metal debris in a molten state, metal debris is formed after the sparks cool down, and these metal debris will adhere to the sponge block 104, so that after gradual accumulation, the sponge cannot quickly cool the sparks. Therefore, when the sparks collide with the sponge block 104, the filter screen 103 can be used to prevent the sparks from contacting the sponge block 104 over a large area, so that the metal debris will not be tightly attached to the sponge block 104. Subsequently, during the process of folding and unfolding the windshield 4, the protrusion 201 It will contact the extrusion block 202, so that the extrusion block 202 squeezes the protrusion 201, so that during the folding and unfolding of the wind shield 4, the left and right filters 103 can be shaken up and down, thereby cleaning up the metal debris attached to the sponge block 104, and in the process of the filter 103 shaking up and down, the cleaning plate 203 can be driven by the filter 103 to shake up and down, thereby cleaning up the metal debris on the middle filter 103, so that the metal debris cannot be accumulated on the sponge block 104, thereby maintaining the cooling effect of the sponge block 104.

Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
