Description

Technical Field

[0001] The present invention relates to a welding device, in particular to a welding device for green building construction applied to the field of building construction technology. Background Art

[0002] A green building refers to a building that maximally saves resources, protects the environment and reduces pollution throughout its life cycle, provides people with healthy, applicable and efficient use spaces, and coexists in harmony with nature. During the construction process of a green building, there may be certain deviations between the actual situation at the construction site and the design. It is often necessary to adjust and connect building components in real time by welding according to the actual situation.

[0003] The invention patent with the publication number of CN116571928B discloses a building construction welding device and its using method, which can effectively solve the technical problem that the existing welding device relies extremely on the active correction of the welder during the vertical and rapid welding of steel bars or hollow pipes, resulting in an increased workload and a decreased work efficiency.

[0004] The invention patent with the publication number of CN117324843B discloses a welding device for steel structure building construction, which can stably fix steel pipes during the welding process and can also flexibly adjust the angles of the steel pipes on both sides, thus avoiding welding errors between the steel pipes and ensuring the welding quality.

[0005] During the construction process of a green building, there may be many types of building components that need to be welded, such as steel plates, steel pipes, steel bars, etc. These components have different shapes and sizes. When welding, the fixation of the components is very crucial. Once the components move during the welding process, the welding quality will be greatly affected. However, the existing welding devices in the prior art have great limitations when fixing building components with different shapes and sizes. They cannot be flexibly adjusted according to the shape and size of the components, or different jigs need to be replaced to fix components with different shapes and sizes, which is very troublesome and has poor practicability. Therefore, we propose a welding device for green building construction. Summary of the Invention

[0006] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing welding devices in the prior art have great limitations when fixing building components with different shapes and sizes.

[0007] To solve the above problems, the present invention provides a welding device for green building construction, which includes a pair of welding tables and a pair of clamping and fixing mechanism. A connecting seat is fixedly connected between the pair of welding tables, and the top end of the connecting seat is lower than the top end of the welding tables. The pair of clamping and fixing mechanisms correspond to the pair of welding tables respectively. The clamping and fixing mechanism includes a supporting linkage cylinder located above the welding table. The bottom end of the supporting linkage cylinder is open. A pair of clamping seats are rotatably connected to the inner side of the supporting linkage cylinder. An upward adjustment cylinder is fixedly installed on the inner wall of the top end of the supporting linkage cylinder. The output end of the upward adjustment cylinder is fixedly connected with a seat cover. The bottom end of the seat cover is open, and the seat cover covers the outside of the pair of clamping seats. The clamping seats are in the shape of a right-angled trapezoid with a thinner upper part and a thicker lower part. The two ends of the pair of clamping seats away from each other are in contact with the inner wall of the seat cover, and the end of the clamping seat in contact with the inner wall of the seat cover is its inclined surface end. The bottom end of the clamping seat is lower than the bottom end of the seat cover, and the bottom end of the seat cover is lower than the bottom end of the supporting linkage cylinder. The clamping and fixing mechanism further includes a hydraulic cylinder fixedly installed on the connecting seat, and the output end of the hydraulic cylinder is fixedly connected with the supporting linkage cylinder.

[0008] In the above welding device for green building construction, the clamping and fixing mechanism can be adjusted adaptively according to the shape and size of the building components to be welded, and can be applied to the fixing and welding of various building components with different shapes and sizes, greatly reducing the limitations of the welding device and greatly improving the practicability of the welding device.

[0009] As a further improvement of the present application, a limiting block fixedly installed on the inner wall of the supporting linkage cylinder is arranged between the pair of clamping seats. The two ends of the limiting block are in contact with the two clamping seats respectively, and the limiting block can play a limiting role.

[0010] As another improvement of the present application, the welding table is a box-type structure with a cavity inside. A U-shaped thick part insertion slot is opened in the middle of the top end of the welding table. A downward adjustment cylinder is fixedly installed inside the welding table. A complementary slot seat matching with the thick part insertion slot is arranged inside the thick part insertion slot. A thin part insertion slot is opened in the middle of the top end of the complementary slot seat.

[0011] As a supplement to another improvement of the present application, the output end of the downward adjustment cylinder is fixedly connected with the bottom end of the complementary slot seat. The complementary slot seat is slidably connected with the thick part insertion slot, and the top end of the complementary slot seat is flush with the top end of the welding table. The pair of clamping seats are symmetrical about the thin part insertion slot, so that when welding circular building components, not only the fixing effect can be further improved, but also the adaptive adjustment can be further carried out according to the size of the components.

[0012] As another improvement of the present application, an elastic balloon is arranged between a pair of pressure card holders. A gas guide hose is communicated with the elastic balloon. An inner side of the support linkage cylinder is provided with a linkage piston plate which is slidably and sealingly connected thereto. The card holder cover penetrates through the linkage piston plate and is fixedly connected thereto in a sealed manner. One end of the gas guide hose away from the elastic balloon penetrates through an outer wall of a top end of the card holder cover and extends to be communicated with a region above the linkage piston plate, so that the pressure card holder can swing automatically without manual swinging by staff, improving convenience.

[0013] As a supplement to another improvement of the present application, the welding device further includes a combined jetting assembly. The combined jetting assembly includes an air storage tank located between two support linkage cylinders. A bottom end of the air storage tank is communicated with an air outlet pipe. One end of the air outlet pipe away from the air storage tank is connected with a jetting gun. Air inlet pipes are communicated with outer walls on left and right sides of the air storage tank respectively. One ends of the two air inlet pipes away from the air storage tank are respectively communicated with the two support linkage cylinders. A push air plate which is slidably and sealingly connected thereto is arranged in the air storage tank. A spring is fixedly connected between the push air plate and an inner wall of a top end of the air storage tank. The air inlet pipes are located below the push air plate.

[0014] As a supplement to another improvement of the present application, an air suction pipe is communicated with an outer wall of a top end of the support linkage cylinder. A top end of the air suction pipe is connected with an air suction one-way valve. The one-way conduction direction of the air suction one-way valve is from outside the support linkage cylinder to inside the support linkage cylinder.

[0015] As a supplement to another improvement of the present application, an air inlet one-way valve is arranged on the air inlet pipe. The one-way conduction direction of the air inlet one-way valve is from inside the support linkage cylinder to inside the air storage tank.

[0016] As a supplement to another improvement of the present application, a plurality of air guide holes are formed in an outer wall of a top end of the air storage tank, so that air can flow more easily from inside the support linkage cylinder to inside the air storage tank. A gun inserting sleeve for placing the jetting gun is fixedly installed on an outer wall of the air storage tank. The jetting gun is movably inserted into the gun inserting sleeve, so that the jetting gun is convenient to place and take.

[0017] In summary, through the setting of the card-pressing firmware mechanism in the present application, the card-pressing firmware mechanism can be adaptively adjusted according to the shape and size of the building component to be welded, and can be applied to the fixation and welding of building components with various different shapes and sizes. Moreover, the fixation effect is good, and the component is not likely to move during the welding process, greatly reducing the limitations of the welding device and greatly improving the practicality of the welding device. Through the combined setting of the rough component insertion slot, the downward adjustment cylinder, etc., when welding a circular building component, not only can the fixation effect be further improved, but also it can be further adaptively adjusted according to the size of the component, further improving the practicality of the welding device. Through the setting of the elastic balloon, the air guide hose, and the linkage piston plate, the card-pressing seat can swing automatically without manual swinging by the staff, improving the convenience. Through the setting of the combined jet component, through the combined setting of the linkage piston plate, the combined jet component, etc., when the upward adjustment cylinder drives the card seat cover to move upward for adjustment, air can also be filled into the air storage tank, and then the air flow can be directionally ejected through the jet gun. The air flow can be used for aspects such as cooling the welding area and cleaning the welding area, further improving the practicality of the welding device. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0030] The following will describe in detail the three implementation manners of this application with reference to the accompanying drawings.

[0031] The first implementation manner:

[0032] Figures 1-4 A welding device for green building construction is shown, including a pair of welding tables 101 and a pair of pressure clamping and fixing mechanisms. A connecting seat 102 is fixedly connected between the pair of welding tables 101. The top end of the connecting seat 102 is lower than the top end of the welding table 101. The pair of pressure clamping and fixing mechanisms respectively correspond to the pair of welding tables 101. The pressure clamping and fixing mechanism includes a support linkage cylinder 201 located above the welding table 101. The bottom end of the support linkage cylinder 201 is set to be open. A pair of pressure clamping seats 202 are rotatably connected to the inner side of the support linkage cylinder 201. An upward adjustment cylinder 203 is fixedly installed on the inner wall of the top end of the support linkage cylinder 201. The output end of the upward adjustment cylinder 203 is fixedly connected with a clamping seat cover 204. The bottom end of the clamping seat cover 204 is set to be open, and the clamping seat cover 204 covers the outside of the pair of pressure clamping seats 202. The pressure clamping seat 202 is set in the shape of a right-angled trapezoid with a thinner upper part and a thicker lower part. The mutually remote ends of the pair of pressure clamping seats 202 are in contact with the inner wall of the clamping seat cover 204, and the end of the pressure clamping seat 202 in contact with the inner wall of the clamping seat cover 204 is its inclined surface end. The bottom end of the pressure clamping seat 202 is lower than the bottom end of the clamping seat cover 204, and the bottom end of the clamping seat cover 204 is lower than the bottom end of the support linkage cylinder 201. The pressure clamping and fixing mechanism further includes a hydraulic cylinder 205 fixedly installed on the connecting seat 102. The output end of the hydraulic cylinder 205 is fixedly connected with the support linkage cylinder 201.

[0033] When welding building components, for building components with shape types such as flat plates and I-beams (such as steel plates, metal roof panels, I-beams, etc.), such building components can be directly placed on the welding table 101, and then the hydraulic cylinder 205 is controlled to drive the support linkage cylinder 201, etc. to move downward until the bottom end of the pressure clamping seat 202 firmly abuts against the component (refer to Figure 4 the upper half part). The component can be fixed, and then welding can be started. Welding uses existing technologies, and those skilled in the art can select a suitable welding method according to the situation, which will not be elaborated here. For building components with shape types such as circular (including circular tubes, cylindrical, etc.) and V-shaped (such as steel pipes, angle steels, etc.), according to the size of such building components, the upward adjustment cylinder 203 is started to drive the clamping seat cover 204 to move upward by a certain distance (the larger the component size, the greater the corresponding upward adjustment distance). After the clamping seat cover 204 moves upward, the two pressure clamping seats 202 can swing in the direction away from each other until the inclined end of the pressure clamping seat 202 abuts against the inner wall of the clamping seat cover 204 again (the larger the upward adjustment distance, the greater the maximum angle that the pressure clamping seat 202 can swing), so that the ends of the two pressure clamping seats 202 close to each other are adjusted into a "V" shape. The component is placed on the welding table 101 and the component is positioned between the two pressure clamping seats 202. Then the hydraulic cylinder 205 is controlled to drive the support linkage cylinder 201, etc. to move downward until the two pressure clamping seats 202 firmly clamp the component (refer to Figure 4 the lower half part). The component can be fixed, and then welding can be started;

[0034] Therefore, through the setting of the pressure clamping and fixing mechanism, the pressure clamping and fixing mechanism can be adaptively adjusted according to the shape and size of the building component to be welded, and can be applied to the fixing and welding of building components with various different shapes and sizes, and has a good fixing effect. The component is not easy to move during the welding process, greatly reducing the limitations of the welding device and greatly improving the practicability of the welding device.

[0035] Please refer to Figure 3 , a limit block 206 fixedly installed on the inner wall of the support linkage cylinder 201 is arranged between a pair of pressure clamping seats 202. The two ends of the limit block 206 respectively abut against the two pressure clamping seats 202. The limit block 206 can play a limiting role. When fixing and welding building components with shape types such as flat plates and I-beams, the limit block 206 can prevent the two pressure clamping seats 202 from swinging in the direction close to each other.

[0036] The second implementation method:

[0037] Figures 5-7There is shown a welding device for green building construction. Different from the first embodiment, the welding table 101 is a box-type structure with a cavity inside. In the middle of the top of the welding table 101, there is a U-shaped thick part insertion slot 103. Inside the welding table 101, a downward adjustment cylinder 104 is fixedly installed. Inside the thick part insertion slot 103, there is a complementary slot seat 105 that matches it. In the middle of the top of the complementary slot seat 105, there is a thin part insertion slot 106. The output end of the downward adjustment cylinder 104 is fixedly connected to the bottom end of the complementary slot seat 105. The complementary slot seat 105 is slidably connected to the thick part insertion slot 103, and the top of the complementary slot seat 105 is flush with the top of the welding table 101. A pair of pressing and clamping seats 202 are symmetric about the thin part insertion slot 106.

[0038] For circular building components, when placing the components, if the diameter of the component is relatively small, the component can be directly placed inside the thin part insertion slot 106. The component is initially clamped by the thin part insertion slot 106. In this way, on the one hand, it can play a certain fixing role to prevent the component from rolling before being fixed by the pressing and clamping fastener mechanism. On the other hand, it can play a positioning role, enabling the component to be accurately positioned between the two pressing and clamping seats 202. Additionally, when fixing the component by the pressing and clamping fastener mechanism, the limit clamping block 206 can clamp the component from below (refer to the left half of Figure 7 ), thereby further improving the fixing effect of the component. If the diameter of the component is relatively large, in this case, the fixing role that the thin part insertion slot 106 can play will be very limited. At this time, the downward adjustment cylinder 104 can be controlled to drive the complementary slot seat 105 to move downward a certain distance, and then the component is placed inside the thick part insertion slot 103. The component is initially clamped by the thick part insertion slot 103 (refer to the right half of Figure 7 ); Therefore, through the combined setting of the thick part insertion slot 103, the downward adjustment cylinder 104, etc., when welding circular building components, not only can the fixing effect be further improved, but also it can be further adjusted adaptively according to the size of the component, further improving the practicality of the welding device.

[0039] The third embodiment:

[0040] Figures 8-10There is shown a welding device for green building construction. Different from the first and second embodiments, an elastic balloon 301 is arranged between a pair of pressing clamping seats 202. A gas guiding hose 302 is communicated with the elastic balloon 301. An inner side of the supporting linkage cylinder 201 is provided with a linkage piston plate 303 which is slidably and sealingly connected thereto. The clamping seat cover 204 penetrates through the linkage piston plate 303 and is fixedly connected thereto in a sealed manner. One end of the gas guiding hose 302 away from the elastic balloon 301 penetrates through an outer wall of a top end of the clamping seat cover 204 and extends to be communicated with a region above the linkage piston plate 303. When the control lifting cylinder 203 drives the clamping seat cover 204 to move upward, the linkage piston plate 303 will also move upward therewith. The upward movement of the linkage piston plate 303 will squeeze the air above it, so that part of the air enters the elastic balloon 301 through the gas guiding hose 302, causing the elastic balloon 301 to expand. The expansion of the elastic balloon 301 will squeeze the pressing clamping seats 202, causing the two pressing clamping seats 202 to swing in a direction away from each other, so that the pressing clamping seats 202 can swing automatically without manual swinging by staff, improving convenience.

[0041] The welding device further includes a combined jetting assembly. The combined jetting assembly includes an air storage tank 401 located between the two supporting linkage cylinders 201. A gas outlet pipe 402 is communicated with a bottom end of the air storage tank 401. One end of the gas outlet pipe 402 away from the air storage tank 401 is connected with a jetting gun 403 (a switch is arranged on the jetting gun 403). Air inlet pipes 404 are communicated with outer walls on left and right sides of the air storage tank 401 respectively. One ends of the two air inlet pipes 404 away from the air storage tank 401 are respectively communicated with the two supporting linkage cylinders 201. A pushing air plate 405 which is slidably and sealingly connected thereto is arranged in the air storage tank 401. A spring 406 is fixedly connected between the pushing air plate 405 and an inner wall of a top end of the air storage tank 401. The air inlet pipes 404 are located below the pushing air plate 405.

[0042] When the control lifting cylinder 203 drives the clamping seat cover 204 to move upward, the extrusion of air by the linkage piston plate 303 will not only cause the air to enter the elastic balloon 301 through the air guide hose 302, but also cause part of the air to enter the air storage tank 401 through the air inlet pipe 404. The entry of air will upwardly squeeze the air pushing plate 405, causing the air pushing plate 405 to move upward and compress the spring 406. During the welding process, the operator can hold the air jet gun 403 and press the switch on the air jet gun 403 to eject an air stream. This air stream can be used for cooling the welding area, cleaning the welding area, etc. Moreover, whether it is ejecting the air stream or the elastic balloon 301 expanding to make the pressure clamping seat 202 swing automatically, it is realized by the lifting cylinder 203. This not only enriches the functions of the lifting cylinder 203 and gives full play to the role of the lifting cylinder 203, but also does not require additional driving components. Therefore, through the combined setting of the linkage piston plate 303, the combined jetting component, etc., when the lifting cylinder 203 drives the clamping seat cover 204 to move upward for adjustment, air can also be filled into the air storage tank 401, and then the air stream can be directionally ejected through the air jet gun 403. The air stream can be used for cooling the welding area, cleaning the welding area, etc., further improving the practicability of the welding device.

[0043] An air suction pipe 407 is connected to the outer wall of the top end of the support linkage cylinder 201. The top end of the air suction pipe 407 is connected with an air suction one-way valve 408. The one-way conduction direction of the air suction one-way valve 408 is from the outside of the support linkage cylinder 201 to the inside of the support linkage cylinder 201. When the lifting cylinder 203 drives the clamping seat cover 204 to move downward, air can be sucked into the support linkage cylinder 201 through the air suction pipe 407 and the air suction one-way valve 408.

[0044] An air inlet one-way valve 410 is arranged on the air inlet pipe 404. The one-way conduction direction of the air inlet one-way valve 410 is from the inside of the support linkage cylinder 201 to the inside of the air storage tank 401. Through the settings of the air suction pipe 407, the air suction one-way valve 408, and the air inlet one-way valve 410, before fixing the building component, by controlling the up and down movement of the clamping seat cover 204 and the linkage piston plate 303 of the lifting cylinder 203 back and forth, air can be continuously filled into the air storage tank 401. On the one hand, it enables more and more sufficient air streams to be ejected through the air jet gun 403. On the other hand, when welding building components of flat shape, I-shaped shape, etc., this function of ejecting air streams can also be used.

[0045] A plurality of air guide holes 409 are formed in the outer wall of the top end of the air storage tank 401, making it easier for air to flow from the inside of the support linkage cylinder 201 to the inside of the air storage tank 401. An insertion gun sleeve 411 for placing the air jet gun 403 is fixedly installed on the outer wall of the air storage tank 401. The air jet gun 403 is movably inserted into the insertion gun sleeve 411, making the air jet gun 403 convenient to place and retrieve.

[0046] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the scope of protection is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
