Description

Technical Field

[0001] The invention belongs to the technical field of electroslag pressure welding, in particular to an electroslag pressure welding device and a construction method for shear wall construction. Background Art

[0002] In shear wall construction, the application of electroslag pressure welding equipment has significant advantages. First, it can achieve direct connection between steel bars without the need for additional connectors, thereby improving the integrity and stability of the shear wall structure. Second, electroslag pressure welding technology has high welding quality, and the weld strength is close to the parent material strength, which can effectively ensure the bearing capacity and seismic performance of the shear wall.

[0003] Before welding two steel bars, you must ensure that their ends are aligned and fit tightly. Next, place the flux box over the ends of the two steel bars and pour flux into the box. The welding arc is ignited between the two steel bars, and the heat generated by the arc melts the ends of the steel bars.

[0004] After the steel bar is welded, it is necessary to open the flux box and use tools to recover the flux inside so that it can be used next time. Although this operation is simple, it has many steps. If this series of operations is repeated frequently, it will not only reduce the efficiency of steel bar welding, but also make people feel boring and even bored due to long-term repetitive labor, which will affect the operator's work efficiency.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 7 As shown, an electroslag pressure welding device for shear wall construction according to an embodiment of the present invention comprises a welding machine 1, an operating box 2, and a flux box composed of a first arc plate 25 and a second arc plate 26; A first mounting seat 3 is slidably mounted below the operation box 2, a first positioning handle 11 for placing the upper steel bar is fixedly mounted on the first mounting seat 3, a first mounting box 4 is fixedly mounted on the first mounting seat 3, and a first pressing rod 5 for pressing the upper steel bar is connected to the internal thread of the first mounting box 4; The upper steel bar can be placed inside the first positioning handle 11, and then the first pressing rod 5 is rotated to slide toward the upper steel bar in the first positioning handle 11 until the first pressing rod 5 presses the upper steel bar, at which time the upper steel bar will be fixed on the first positioning handle 11.

[0024] A second mounting seat 7 is provided below the first mounting seat 3, a second positioning handle 12 for placing the lower steel bar is fixedly mounted on the second mounting seat 7, a second mounting box 9 is fixedly mounted on the second mounting seat 7, and a second pressing rod 10 for pressing the lower steel bar is connected to the inner thread of the second mounting box 9; The central axis of the second mounting seat 7 coincides with that of the first mounting seat 3, and the second positioning handle 12 is placed on the lower steel bar. The second pressing rod 10 is then controlled to rotate to move the second pressing rod 10 toward the lower steel bar until the second pressing rod 10 presses the lower steel bar. At this time, the lower steel bar can be fixed inside the second positioning handle 12. Since the first mounting seat 3 is arranged below the operating box 2, the second mounting seat 7 coincides with the center of the first mounting seat 3. Therefore, when the upper steel bar is fixed in the first positioning handle 11 and the lower steel bar is fixed in the second positioning handle 12, the axis of the upper steel bar and the lower steel bar will coincide, which is used to improve the accuracy of welding the upper steel bar and the lower steel bar.

[0025] A collecting box 18 is fixedly mounted on the second mounting seat 7, and a material guide platform 17 is arranged below the flux box, and the other end of the material guide platform 17 extends to the interior of the collecting box 18; The material guide table 17 is tilted toward the collecting box 18. When the first arc plate 25 and the second arc plate 26 are opened, the flux inside will fall onto the material guide table 17. Since the material guide table 17 is tilted, the flux falling onto the material guide table 17 will enter the collecting box 18. A filter net can be set inside the collecting box 18, and the iron slag in the flux can be filtered through the set filter net.

[0026] A material table 16 is fixedly mounted on the operation box 2, a conveying pipe 24 is arranged between the material table 16 and the collecting box 18, a feeding pipe 23 is arranged at the bottom end of the material table 16, and one end of the feeding pipe 23 extends to the inside of the flux box.

[0027] The top of the material platform 16 is provided with a material port, through which flux can be added. The flux in the material platform 16 can be transported to the inside of the flux box through the provided feeding pipe 23, so as to facilitate welding of the upper and lower steel bars.

[0028] A spiral auger is disposed inside the conveying pipe 24 for conveying the flux in the collecting box 18 to the inside of the material table 16, so that the recovered flux can be used quickly and conveniently. The spiral auger can be controlled by a power motor.

[0029] As a preferred embodiment of the present invention, a threaded rod 13 is rotatably installed inside the operating box 2, one end of the threaded rod 13 passes through the first mounting seat 3 and is threadedly connected to the first mounting seat 3, a sleeve 8 is fixedly installed on the second mounting seat 7, and one end of the threaded rod 13 extends to the interior of the sleeve 8.

[0030] When the threaded rod 13 rotates, the first mounting seat 3 will be driven to slide on the surface of the threaded rod 13 through thread transmission. The first mounting seat 3 can be controlled to slide up or down by the forward and reverse rotation of the threaded rod 13. At this time, after the first positioning handle 11 and the first pressing rod 5 clamp the upper steel bar, the sliding of the first mounting seat 3 will drive the upper steel bar to slide synchronously. After the flux box is installed between the upper steel bar and the lower steel bar, the flux placed inside the flux box cooperates with the current of the welding machine 1 to melt the ends of the upper steel bar and the lower steel bar. At this time, by controlling the rotation of the threaded rod 13, the upper steel bar is continuously fed downward, so that its end can be inserted into the slag pool to form a molten connection with the end face of the lower steel bar.

[0031] As a preferred embodiment of the present invention, a worm wheel 14 is fixedly mounted on the top of the threaded rod 13 , a worm 15 is rotatably mounted inside the operating box 2 , one end of the worm 15 extends out of the outer wall of the operating box 2 , and the worm wheel 14 is meshed with the worm 15 .

[0032] The worm gear 14 is driven to rotate by rotating the worm 15 , and the threaded rod 13 is driven to rotate by the rotation of the worm gear 14 , thereby controlling the movement of the first mounting seat 3 .

[0033] As a preferred embodiment of the present invention, a sliding cylinder 6 is provided on the sleeve 8, a control plate 19 is fixedly mounted on the sliding cylinder 6, the first arc plate 25 and the second arc plate 26 are both connected to the control plate 19 through a connecting rod 21, and the first arc plate 25 and the second arc plate 26 are hinged; The first arc plate 25 and the second arc plate 26 can rotate relative to each other to form a complete tube, that is, a flux tube. When the first arc plate 25 and the second arc plate 26 are opened, the flux in the flux tube will fall out.

[0034] The sliding cylinder 6 is a telescopic cylinder, and the control plate 19 can only move horizontally but not vertically by means of the sliding cylinder 6 .

[0035] The first pushing rod 5 passes through the control board 19, and a limiting plate is arranged on the first pushing rod 5. The control board 19 and the first pushing rod 5 can be bound to each other through the limiting plate. When the first pushing rod 5 slides, the control board 19 will be driven to slide synchronously. A sliding groove is provided on the first pushing rod 5 for the first pushing rod 5 to slide up and down in the control board 19. When the first mounting seat 3 slides, the first pushing rod 5 will be driven to slide in the sliding groove, which will not affect the movement of the control board 19.

[0036] When the first push rod 5 drives the control plate 19 to slide toward the steel bar, the control plate 19 will push the first arc plate 25 and the second arc plate 26 through the connecting rod 21, so that the first arc plate 25 and the second arc plate 26 rotate relative to each other and form a flux box.

[0037] When the first push rod 5 drives the control plate 19 to slide in the direction away from the steel bar, the first arc plate 25 and the second arc plate 26 will be separated by the connecting rod 21. It should be noted that the top ends of the first arc plate 25 and the second arc plate 26 are in contact with the bottom end of the first positioning handle 11 after the upper steel bar is driven to slide down and welded.

[0038] As a preferred embodiment of the present invention, a first baffle 39 is fixedly installed inside the first arc plate 25 , a second baffle 40 is fixedly installed inside the second arc plate 26 , and a pressure rod 27 is elastically installed inside the first baffle 39 and the second baffle 40 .

[0039] The first baffle plate 39 and the second baffle plate 40 are both arc plates, which are used to seal the bottom of the first arc plate 25 and the second arc plate 26 to prevent the flux from falling. When the first arc plate 25 and the second arc plate 26 rotate relative to each other and form a flux box, the first baffle plate 39 and the second baffle plate 40 will also form a blocking plate, and a blocking cloth is provided at the center position of the first baffle plate 39 and the second baffle plate 40 to seal the gap between the first baffle plate 39 and the second baffle plate 40 and the steel bars. By controlling the pressure rod 27 in the first baffle plate 39 and the second baffle plate 40 to slide toward the position of the steel bars, the blocking cloth will be pressed, which can effectively reduce the gap between the steel bars and reduce the flux from falling.

[0040] As a preferred embodiment of the present invention, a control ring 31 is elastically installed inside the first arc-shaped plate 25, an arc-shaped push block 28 is fixedly installed at one end of the control ring 31 close to the pressing rod 27, a pull rod 29 is fixedly installed at the top of the control ring 31, and a connecting block 22 is fixedly installed on the control plate 19, and the connecting block 22 is connected to the pull rod 29 through a pull rope 30; A tension spring is fixedly connected to one end of the control ring 31 away from the control plate 19. When the first push rod 5 slides in the direction away from the first positioning handle 11, the control plate 19 will synchronously move in the direction away from the first curved plate 25 and the second curved plate 26. At this time, the connecting block 22 will pull the pull rope 30 to make the inside of the first curved plate 25 in the control ring 31 slide toward the control plate 19. At the same time, the tension spring will also deform to store elastic potential energy. At this time, the arc push block 28 will also release the pressure on the pressure rod 27.

[0041] When the first pushing rod 5 drives the control plate 19 to slide in the direction of the first curved plate 25 and the second curved plate 26, the tension spring releases its elastic potential energy, which can drive the control ring 31 to rotate counterclockwise and drive the arc-shaped push block 28 to rotate. At this time, the arc-shaped push block 28 can press one end of the pressure rod 27 through the inclined surface of the inner wall, so that the pressure rod 27 moves in the direction of the steel bar, which will press the blocking cloth to contact the steel bar and reduce the gap. At this time, the reset spring arranged on the outer wall of the pressure rod 27 will also be in a deformed state. When the control ring 31 drives the arc-shaped push block 28 to rotate clockwise, the pressure rod 27 that is not pressed will be reset under the action of the reset spring, thereby releasing the pressure on the blocking cloth.

[0042] The second arc-shaped plate 26 is also provided with a control ring 31 , an arc-shaped push block 28 , a pressing rod 27 , a pull rod 29 and a pull rope 30 .

[0043] The internal structure of the second curved plate 26 is consistent with the internal structure of the first curved plate 25 .

[0044] As a preferred embodiment of the present invention, a placement tube 32 is fixedly installed inside the material table 16, a feed port 33 is opened at the top of the placement tube 32, a push block 34 is slidably installed inside the placement tube 32, a feeding trough 38 is opened at the bottom end of the material table 16, and one end of the feeding tube 23 is connected to the feeding trough 38.

[0045] When the push block 34 is located at the leftmost side of the placement tube 32, there is space between the push block 34 and the feed port 33, so the flux inside the material table 16 will enter the interior of the placement tube 32 through this space, and then the flux in the placement tube 32 will be fed into the interior of the feed tube 23 through the feed trough 38.

[0046] When the push block 34 slides toward the right inside the placement tube 32 and blocks the feed port 33 , the flux in the material table 16 cannot enter the placement tube 32 , and the flux cannot be transported into the flux box through the feed tube 23 .

[0047] As a preferred embodiment of the present invention, the pushing block 34 is fixedly connected to the moving block 35 through a connecting rod, a first magnet is arranged at the bottom end of the moving block 35, a second magnet 20 for attracting the first magnet is fixedly installed at the top end of the control board 19, a connecting groove 37 is opened at the bottom end of the moving block 35, the connecting groove 37 is connected to the feeding groove 38, a material guide plate 36 is arranged between the pushing block 34 and the moving block 35, and the top end of the material guide plate 36 is inclined.

[0048] When the pushing block 34 moves, it will drive the moving block 35 to move synchronously. When the moving block 35 slides to the right side of the feeding trough 38, the connecting groove 37 opened at the bottom of the placement tube 32 connects the inner cavity of the placement tube 32 with the feeding trough 38. If the moving block 35 is located on the left side of the feeding trough 38, the placement tube 32 and the feeding trough 38 are not connected.

[0049] Therefore, when the pushing block 34 is located at the leftmost side of the placement tube 32, the moving block 35 is located on the left side of the feeding trough 38, and the flux in the material table 16 can enter the interior of the placement tube 32 through the feed port 33, and the flux is transported to the connecting groove 37 through the guide plate 36 until the moving block 35 moves to the right side of the feeding trough 38. At this time, the flux in the connecting groove 37 will enter the interior of the feeding tube 23 through the feeding trough 38, and finally enter the flux box.

[0050] By setting the first magnet box and the second magnet 20, the control board 19 can synchronize the movement of the moving block 35. Therefore, when the control board 19 controls the combination of the first curved plate 25 and the second curved plate 26 through the connecting rod 21, the moving block 35 will be located on the right side of the feeding trough 38. At this time, the feeding pipe 23 will synchronously transport a certain amount of flux toward the inside of the flux box. The operation is simple and continuous, which improves the efficiency of steel bar welding.

[0051] This embodiment also provides a shear wall construction electroslag pressure welding construction method, which uses the above-mentioned shear wall construction electroslag pressure welding device and includes the following steps: S1: First, place the second positioning handle 12 on the lower steel bar, place the first positioning handle 11 on the upper steel bar, and rotate the second pressing rod 10 and the first pressing rod 5 to lock the upper steel bar and the lower steel bar; S2: Secondly, under the movement of the first push rod 5, the control plate 19 will be driven to move at the same time, and the first arc plate 25 and the second arc plate 26 are controlled to rotate relative to each other through the connecting rod 21, and are sleeved at the connection between the upper steel bar and the lower steel bar. Then, the flux is fed into the flux box through the feeding pipe 23 through the material table 16, and the joint of the welding machine 1 is connected to the upper steel bar to complete the welding of the upper steel bar and the lower steel bar; S3: Finally, the first pressing rod 5 is controlled to release the pressing force on the upper steel bar. At the same time, the control plate 19 separates the first arc plate 25 and the second arc plate 26 through the connecting rod 21. The flux inside the arc plate 25 will enter the interior of the collecting box 18 through the material guide table 17. With the cooperation of the conveying pipe 24, the recovered flux will be sent to the material table 16 for continued use.

[0052] Working principle: put the second positioning handle 12 on the lower steel bar, and then control the second pushing rod 10 to rotate so that the second pushing rod 10 moves toward the direction of the lower steel bar until the second pushing rod 10 pushes the lower steel bar. At this time, the lower steel bar can be fixed on the second positioning handle 12, and then the first pushing rod 5 is rotated to slide the first pushing rod 5 toward the upper steel bar in the first positioning handle 11 until the first pushing rod 5 presses the upper steel bar. At this time, the upper steel bar will be fixed on the first positioning handle 11. When the first pushing rod 5 drives the control plate 19 to slide in the direction of the steel bar, the control plate 19 will push the first curved plate 25 and the second curved plate 26 through the connecting rod 21, so that the first curved plate 25 and the second curved plate 26 rotate relative to each other and form a flux box, which can effectively reduce the time required for the installation of the flux box and improve the efficiency of steel bar welding to a certain extent.

[0053] When the first push rod 5 drives the control plate 19 to slide in the direction of the steel bar, the first magnet and the second magnet 20 can synchronize the movement of the control plate 19 and the moving block 35. Therefore, when the control plate 19 controls the combination of the first curved plate 25 and the second curved plate 26 through the connecting rod 21, the moving block 35 will be located on the right side of the feeding trough 38. At this time, the feeding pipe 23 will synchronously transport a certain amount of flux toward the inside of the flux box. The operation is simple and continuous, which improves the efficiency of steel bar welding.
