Description

Technical Field

[0001] The invention relates to the technical field of plate welding, in particular to a steel structure plate welding device for construction. Background Art

[0002] Steel structure is a structure made of steel materials. It is one of the main types of building structures. It has the characteristics of high strength, light weight, fast construction speed, environmental protection and energy saving, and reusability. It is widely used in high-rise buildings, factories, bridges and other fields. During the design and construction process, it is necessary to pay attention to the key links such as reasonable selection of steel types and specifications, full consideration of natural factors, strict control of welding quality and node structure, regular maintenance and inspection. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Steel structures are prone to rust. Generally, steel structures need to be rust-free, galvanized or painted, and maintained regularly.

[0003] After searching, it was found that the patent with publication number CN213615016U proposed an adjustable welding equipment for steel structure, which includes a horizontal support plate frame, a steel clamping platform is arranged above the horizontal support plate frame, and there are two steel clamping platforms, a control panel box is arranged on one side of the steel clamping platform, and the control panel box is connected to the steel clamping platform by screws.

[0004] The above patent document mainly clamps and fixes the steel body through the extended support rods on the left and right sides. When it needs to be turned over during the welding process, the support plates on the upper and lower sides simply support the steel to avoid displacement and misalignment during the rotation. However, in actual application, when welding steel structure sheet metal, the above device lacks a mechanism for rapid cooling of the steel structure sheet metal, resulting in the steel structure sheet metal taking a long time to naturally dissipate heat, and the work efficiency is low. At the same time, the existing welding device also lacks the ability to weld both sides of the sheet metal at the same time, and workers need to re-clamp to weld, which is labor-intensive and has low work efficiency. Therefore, there is an urgent need for a welding device for steel structure panels for construction. Summary of the invention

[0037] Cooling mechanism 8: The inner cavity of the piston cylinder 6 is provided with a cooling mechanism 8, and the cooling mechanism 8 is used to perform air cooling and heat dissipation on the surface of the steel structure plate 4:

[0038] Conveying mechanism 9 : A conveying mechanism 9 is arranged on the side wall of the moving frame 21 , and the conveying mechanism 9 is used to convey the steel structure plate 4 .

The left side plate of the moving frame 21 is detachably connected, the steel structure plate 4 slides in the inner cavity of the moving frame 21, the vertical plate 31 is fixedly installed on the side wall of the right side plate of the moving frame 21, the inner cavities of the two vertical plates 31 are rotatably installed with the clamping worm 32, the bidirectional screw 35 is rotatably installed in the inner cavity of the moving frame 21, and the limit blocks 36 are on the left and right sides of the inner cavity of the moving frame 21;

[0040] The threads on the left and right sides of the inner cavity of the bidirectional screw 35 are in opposite directions. The bidirectional screw 35 is threadedly connected to the limit block 36. The clamping worm wheel 34 is fixedly installed on the right end surface of the bidirectional screw 35. The clamping worm 32 is meshedly connected with the clamping worm wheel 34. The clamping motor 33 is fixedly installed on the right side plate side wall of the moving frame 21 through the frame.

[0041] The clamping seat 37 is slidably installed on the inner wall of the movable frame 21, and a movable column 38 is slidably installed on the inner wall of the clamping seat 37. A clamping plate 39 is fixedly installed on the lower end surface of the movable column 38. The clamping plate 39 fits with the steel structure plate 4. A clamping spring 381 is wound around the side wall of the movable column 38, and a top block 382 is fixedly installed on the upper end surface of the movable column 38. The two ends of the clamping spring 381 are respectively connected to the inner wall of the top block 382 and the outer wall of the clamping seat 37.

[0042] It should be noted that the staff places the steel structure plate 4 between the clamping seats 37 on the left and right sides, and through the movable column 38 set on the side wall of the clamping seat 37, with the cooperation of the clamping spring 381, the clamping plate 39 can be firmly pressed against the side wall of the steel structure plate 4. At this time, the entire device can achieve preliminary fixation of the steel structure plate 4. After several groups of steel structure plates 4 are clamped in the moving frame 21, the clamping motor 33 can be started to make the clamping worm 32 drive the bidirectional screw 35 to rotate. Since the clamping worm 32 is meshed and connected with the clamping worm wheel 34, and the inner cavity of the bidirectional screw 35 on both sides has opposite thread directions on the left and right sides, the limit blocks 36 on the left and right sides will be approached at the same time, so that all the steel structure plates 4 are pressed together. At this time, the entire device can complete the final fixation of the steel structure plate 4.

[0043] Further, the welding mechanism 7 includes a transmission shaft 71, a transmission worm 72, a transmission worm wheel 73, a transmission rod 74, a threaded rod 75, a threaded sleeve 76, an electric telescopic rod 77 and a spot welder 78. The output shaft ends on both sides of the dual-axis motor 5 are fixedly installed with the transmission shaft 71, the transmission worm 72 is fixedly installed in the middle of the outer wall of the transmission shaft 71, the transmission rod 74 is rotatably installed on the upper and lower sides of the inner cavity of the fixed frame 2, the threaded rod 75 is fixedly installed in the middle of the outer wall of the transmission rod 74, the threaded sleeve 76 is threadedly installed on the outer wall of the threaded rod 75, and the spot welder 78 is fixedly installed on the side wall of the threaded sleeve 76 through the electric telescopic rod 77;

[0044] A transmission worm wheel 73 is fixedly mounted on the upper end surface of the transmission rod 74 , the transmission worm 72 is meshedly connected with the transmission worm wheel 73 , the threaded sleeve 76 slides on the inner cavity side wall of the fixed frame 2 , and the spiral directions of the threaded rods 75 on the upper and lower sides are opposite.

[0045] It should be noted that, when a specific program in the dual-axis motor 5 is running, the dual-axis motor 5 will reverse, and the dual-axis motor 5 will drive the transmission shaft 71 to rotate the transmission worm 72, and at this time the transmission worm 72 will also drive the transmission worm wheel 73 to cause the transmission rod 74 to rotate in the opposite direction (such as Figure 7As shown in the figure, under the cooperation of the empty slot 941 provided in the inner cavity of the ratchet 94, the compression spring 943 will be compressed, so that the ratchet 942 is accommodated in the empty slot 941, and the gear 92 will not rotate. At this time, the moving frame 21 will be in a stationary state, and the spot welder 78 will move left and right on the side wall of the steel structure plate 4. Through the setting of the electric telescopic rod 77, the spot welder 78 can be close to the surface of the steel structure plate 4. At this time, the spot welder 78 can be turned on to realize the function of welding the surface of the entire steel structure plate 4. When the threaded rod 75 rotates in the reverse direction, the threaded rod 75 will also rotate in the reverse direction. Since the threaded rod 75 is threadedly connected with the threaded sleeve 76, under the limiting effect of the fixing frame 2, the threaded sleeve 76 will move from left to right in the inner cavity of the fixing frame 2 to achieve strip welding on the surface of the steel structure plate 4. The welding mechanism 7 is provided with two groups, the upper and lower groups, which can realize the simultaneous processing of the upper and lower surfaces of the steel structure plate 4 at one time, thereby reducing the cost of workers turning over the steel structure plate 4 and effectively improving the efficiency of the whole device in welding the steel structure plate 4.

[0046] Furthermore, the cooling mechanism 8 includes a cam 81, a sliding column 82, a piston plate 83, an air outlet pipe 84 and a blow-off pipe 85. The cams 81 are fixedly mounted at both ends of the outer wall of the transmission shaft 71, the piston plate 83 is slidably mounted in the inner cavity of the piston cylinder 6, the sliding column 82 is fixedly mounted on the upper end surface of the piston plate 83, the air outlet pipe 84 is fixedly mounted on the lower part of the left end surface of the piston cylinder 6, and the blow-off pipe 85 is fixedly mounted on the side wall of the spot welder 78;

[0047] The cam 81 is slidably connected to the sliding column 82, the sliding column 82 is slidably connected to the piston cylinder 6, a return spring 831 is fixedly connected between the piston plate 83 and the bottom surface of the inner cavity of the piston cylinder 6, the air outlet pipe 84 is connected to the blow-off pipe 85, the air outlet pipe 84 is a hose, and the left and right sides of the lower part of the inner cavity of the piston cylinder 6 are respectively provided with an air outlet 61 and an air inlet 62, the air outlet 61 is connected to the air outlet pipe 84, a one-way air valve with its outlet toward the air outlet 61 is provided at the connection between the air outlet 61 and the piston cylinder 6, and a one-way air valve with its outlet toward the inner cavity of the piston cylinder 6 is provided at the connection between the air inlet 62 and the piston cylinder 6.

[0048] It should be noted that when the transmission shaft 71 rotates in the reverse direction, the cam 81 also rotates in the reverse direction. At this time, the cam 81 will drive the sliding column 82 to move the piston plate 83 up and down in the inner cavity of the piston cylinder 6. When the piston plate 83 moves to the lower part of the inner cavity of the piston cylinder 6 (such as Figure 8As shown), at this time, the one-way air valve at the air inlet 62 is in a closed state, the lower inner cavity space of the piston cylinder 6 gradually becomes smaller, and the air pressure in the lower inner cavity of the piston cylinder 6 gradually increases. When the air pressure in the lower inner cavity of the piston cylinder 6 is greater than the threshold of the one-way air valve at the air outlet 61, the one-way air valve at the air outlet 61 will be opened. At this time, the air in the lower inner cavity of the piston cylinder 6 will be ejected from the blow-off pipe 85 through the air outlet pipe 84, which can blow on the welding point of the steel structure plate 4, increase the air flow, improve the efficiency of air cooling at the welding point of the steel structure plate 4, and greatly improve the efficiency of the entire device in welding the steel structure plate 4.

[0049] Furthermore, the conveying mechanism 9 includes a rack belt 91, a gear 92, a ratchet sleeve 93 and a ratchet 94. The rack belt 91 is fixedly mounted on the upper end surface of the moving frame 21, and the ratchet 94 is fixedly mounted on the lower part of the outer wall of the transmission rod 74. The outer wall of the ratchet 94 is meshed and slidably connected with the ratchet sleeve 93, and the gear 92 is fixedly mounted on the outer wall of the ratchet sleeve 93.

[0050] The gear 92 is meshed and connected with the rack belt 91, and a slot 941 is provided on the ratchet 94, a pawl 942 is slidably installed in the inner cavity of the slot 941, and a compression spring 943 is fixedly installed between the pawl 942 and the bottom surface of the inner cavity of the slot 941, a support platform 11 is fixedly installed on the upper end surface of the workbench 1, and a support wheel 12 is rotatably installed on the side wall of the support platform 11, and the steel structure plate 4 rests on the side wall of the support wheel 12.

[0051] It should be noted that the staff can input a specific PLC program into the dual-axis motor 5 and start the dual-axis motor 5 to make it rotate forward. At this time, the dual-axis motor 5 will drive the transmission shaft 71 to rotate the transmission worm 72. Since the transmission worm 72 is threadedly connected with the transmission worm wheel 73, the transmission worm 72 will drive the transmission worm wheel 73 to rotate the transmission rod 74. The transmission rod 74 is fixedly connected to the ratchet 94. At this time, the ratchet 94 will rotate counterclockwise (such as Figure 7 As shown), since the outer wall of the ratchet 94 is meshed and slidably connected with the ratchet sleeve 93, the ratchet 94 will drive the ratchet sleeve 93 to rotate the gear 92, and the gear 92 will drive the rack belt 91 to rotate the rack belt 91. At this time, with the cooperation of the support wheel 12 on the support platform 11, the steel structure plate 4 will be moved, replacing the traditional need to manually move the steel structure plate 4, greatly reducing the labor efficiency of workers.

[0052] Working principle:

[0053] During operation, the staff places the steel structure plate 4 between the clamping seats 37 on the left and right sides, and through the movable column 38 set on the side wall of the clamping seat 37, under the cooperation of the clamping spring 381, the clamping plate 39 can be firmly pressed against the side wall of the steel structure plate 4. At this time, the entire device can achieve the initial fixation of the steel structure plate 4. After a number of groups of steel structure plates 4 are clamped in the moving frame 21, the clamping motor 33 can be started to make the clamping worm 32 drive the bidirectional screw 35 to rotate. Since the clamping worm 32 is meshed and connected with the clamping worm wheel 34, and the inner cavity of the bidirectional screw 35 on both sides has opposite thread directions on the left and right sides, the limit blocks 36 on the left and right sides will be simultaneously approached, so that all the steel structure plates 4 are pressed together. At this time, the entire device can complete the final fixation of the steel structure plate 4.

[0054] When all the steel structure plates 4 to be welded are fixed, the staff can enter a specific PLC program into the double-axis motor 5 and start the double-axis motor 5 to make it rotate forward. At this time, the double-axis motor 5 will drive the transmission shaft 71 to rotate the transmission worm 72. Since the transmission worm 72 is threadedly connected with the transmission worm wheel 73, the transmission worm 72 will drive the transmission worm wheel 73 to rotate the transmission rod 74. The transmission rod 74 is fixedly connected to the ratchet 94. At this time, the ratchet 94 will rotate counterclockwise (such as Figure 7 As shown in the figure, since the outer wall of the ratchet 94 is meshed and slidably connected with the ratchet sleeve 93, the ratchet 94 will drive the ratchet sleeve 93 to rotate the gear 92, and the gear 92 will drive the rack belt 91 to rotate the rack belt 91. At this time, under the cooperation of the support wheel 12 on the support platform 11, the steel structure plate 4 will be moved, replacing the traditional manual movement of the steel structure plate 4, which greatly reduces the labor efficiency of workers;

[0055] With the cooperation of the entire conveying mechanism 9, the steel structure plate 4 will move to the lower part of the spot welding machine 78. At this time, under the specific program operation in the double-axis motor 5, the double-axis motor 5 will reverse, and the double-axis motor 5 will drive the transmission shaft 71 to rotate the transmission worm 72, and at this time the transmission worm 72 will also drive the transmission worm wheel 73 to make the transmission rod 74 rotate in the opposite direction (such as Figure 7As shown in the figure, under the cooperation of the empty slot 941 provided in the inner cavity of the ratchet 94, the compression spring 943 will be compressed, so that the ratchet 942 is accommodated in the empty slot 941, and the gear 92 will not rotate. At this time, the moving frame 21 will be in a stationary state, and the spot welder 78 will move left and right on the side wall of the steel structure plate 4. Through the setting of the electric telescopic rod 77, the spot welder 78 can be close to the surface of the steel structure plate 4. At this time, the spot welder 78 can be turned on to realize the function of welding the surface of the entire steel structure plate 4. When the threaded rod 75 rotates in the reverse direction, the threaded rod 75 will also rotate in the reverse direction. Since the threaded rod 75 is threadedly connected with the threaded sleeve 76, under the limiting effect of the fixing frame 2, the threaded sleeve 76 will move from left to right in the inner cavity of the fixing frame 2 to achieve strip welding on the surface of the steel structure plate 4. The welding mechanism 7 is provided with two groups, the upper and lower groups, which can realize the processing of the upper and lower surfaces of the steel structure plate 4 at one time, thereby reducing the cost of workers turning over the steel structure plate 4 and effectively improving the efficiency of the whole device for welding the steel structure plate 4.

[0056] When the transmission shaft 71 rotates in the reverse direction, the cam 81 also rotates in the reverse direction. At this time, the cam 81 will drive the sliding column 82 to move the piston plate 83 up and down in the inner cavity of the piston cylinder 6. When the piston plate 83 moves to the lower part of the inner cavity of the piston cylinder 6 (such as Figure 8 As shown), at this time, the one-way air valve at the air inlet 62 is in a closed state, the lower inner cavity space of the piston cylinder 6 gradually becomes smaller, and the air pressure in the lower inner cavity of the piston cylinder 6 gradually increases. When the air pressure in the lower inner cavity of the piston cylinder 6 is greater than the threshold of the one-way air valve at the air outlet 61, the one-way air valve at the air outlet 61 will be opened. At this time, the air in the lower inner cavity of the piston cylinder 6 will be ejected from the blow-off pipe 85 through the air outlet pipe 84, which can blow on the welding part of the steel structure plate 4, increase the air flow, improve the efficiency of air cooling at the welding part of the steel structure plate 4, and greatly improve the efficiency of the whole device in welding the steel structure plate 4;

[0057] When the piston plate 83 moves toward the upper part of the inner cavity of the piston cylinder 6 (as shown in FIG. Fig. 9 As shown), at this time, the one-way air valve at the air outlet 61 will be in a closed state, the lower inner cavity space of the piston cylinder 6 will gradually increase, and the air pressure in the lower inner cavity of the piston cylinder 6 will gradually decrease. When the air pressure in the lower inner cavity of the piston cylinder 6 is less than the threshold of the one-way air valve at the air inlet 62, the outside air will enter the inner cavity of the piston cylinder 6 through the air inlet 62 to replenish the air in the inner cavity of the piston cylinder 6, thus making the prerequisite preparation for the next air blowing cooling and heat dissipation on the surface of the steel structure plate 4.

[0058] Therefore, through the above-mentioned, the entire device can realize the rapid transportation of steel structure plates through the setting of clamping mechanism and conveying mechanism, which greatly reduces the labor intensity of workers. At the same time, welding mechanism and cooling mechanism are provided, which can realize the welding of steel structure plates and the cooling of them by air blowing, which greatly improves the working efficiency of the entire device.
