Description

Technical Field

[0001] This invention belongs to the field of electroslag pressure welding technology, specifically an electroslag pressure welding device and construction method for shear wall construction. Background Technology

[0002] The application of electroslag pressure welding equipment in shear wall construction has significant advantages. Firstly, it enables direct connection between reinforcing bars without the need for additional connectors, thereby improving the integrity and stability of the shear wall structure. Secondly, electroslag pressure welding technology produces high-quality welds with weld strength approaching that of the base material, effectively ensuring the load-bearing capacity and seismic performance of the shear wall.

[0003] Before welding two reinforcing bars, ensure their ends are aligned and tightly fitted. Next, place the flux box at the appropriate positions at the ends of the two reinforcing bars, and then pour flux into the box. An electric welding arc is ignited between the two reinforcing bars, and the heat generated melts the ends of the bars.

[0004] After the steel bars are welded, the flux box needs to be opened and tools used to recover the flux inside for future use. Although this operation is simple, it involves 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 bored and even develop a sense of aversion to the long-term repetitive work, thus affecting the operator's work efficiency.

[0005] Therefore, the present invention provides an electroslag pressure welding device and construction method for shear wall construction. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

A first positioning handle for placing the upper rebar is fixedly installed on the first mounting base. A first mounting box is fixedly installed on the first mounting base. A first pressing rod for pressing the upper rebar is threadedly connected inside the first mounting box. A second mounting base is provided below the first mounting base. A second positioning handle for placing the lower rebar is fixedly installed on the second mounting base. A second mounting box is fixedly installed on the second mounting base. A second pressing rod for pressing down the lower rebar is connected internally to the second mounting box. A collection box is fixedly installed on the second mounting base, and a guide platform is provided below the flux box, with the other end of the guide platform extending into the interior of the collection box. A material platform is fixedly installed on the operation box. A conveying pipe is installed between the material platform and the collection box. A feeding pipe is installed at the bottom of the material platform, and one end of the feeding pipe extends into the inside of the flux box.

[0008] A threaded rod is rotatably mounted inside the control box. One end of the threaded rod passes through the first mounting seat and is connected to the first mounting seat by a thread. A sleeve is fixedly mounted on the second mounting seat, and one end of the threaded rod extends into the inside of the sleeve.

[0009] A worm gear is fixedly installed at the top of the threaded rod, and a worm is rotatably installed inside the operating box. One end of the worm extends out of the outer wall of the operating box, and the worm gear meshes with the worm.

[0010] A sliding cylinder is provided on the sleeve, and a control plate is fixedly installed on the sliding cylinder. The first arc plate and the second arc plate are both connected to the control plate through connecting rods, and the first arc plate and the second arc plate are hinged. The first top pressure rod penetrates the control panel.

[0011] A first baffle is fixedly installed inside the first arc-shaped plate, and a second baffle is fixedly installed inside the second arc-shaped plate. Both the first and second baffles are elastically fitted with a pressure bar inside.

[0012] The first arc-shaped plate has a control ring elastically installed inside. An arc-shaped push block is fixedly installed at one end of the control ring near the pressure rod. A pull rod is fixedly installed at the top of the control ring. A connecting block is fixedly installed on the control plate. The connecting block is connected to the pull rod by a pull rope. The second arc-shaped plate also contains a control ring, an arc-shaped push block, a pressure rod, a pull rod, and a pull rope.

[0013] The material platform has a fixed installation tube inside, with an inlet at the top of the tube and a sliding pusher inside. The bottom of the material platform has a feeding trough, and one end of the feeding tube is connected to the feeding trough.

[0014] The push block is fixedly connected to the moving block by a connecting rod. The bottom of the moving block is provided with a first magnet. The top of the control board is fixedly installed with a second magnet for attracting the first magnet. The bottom of the moving block is provided with a connecting groove, which is connected to the feeding groove.

[0015] A guide plate is provided between the push block and the moving block, and the top of the guide plate is inclined.

[0016] A method for electroslag pressure welding in shear wall construction includes the following steps: S1: First, place the second positioning handle on the lower reinforcing bar and the first positioning handle on the upper reinforcing bar. Then, rotate the second and first top pressure rods to lock the upper and lower reinforcing bars. S2: Secondly, the movement of the first top pressure rod will simultaneously drive the control plate to move. The first arc plate and the second arc plate will rotate relative to each other through the connecting rod and be fitted onto the connection between the upper and lower steel bars. Then, the flux will be fed into the flux box through the feeding pipe via the material table, and the joint of the welding machine will be connected to the upper steel bar to complete the welding of the upper and lower steel bars. S3: Finally, control the first top pressure rod to release the pressure on the upper steel bar, and at the same time control the plate to separate the first arc plate and the second arc plate through the connecting rod. The flux inside will then enter the collection box through the guide platform. With the cooperation of the conveying pipe, the recovered flux will be sent into the material platform for continued use.

[0017] The beneficial effects of this invention are as follows: 1. The electroslag pressure welding device and construction method for shear wall construction described in this invention controls the second and first top pressure rods to press down on the lower and upper reinforcing bars. With the cooperation of the control plate, the first and second arc-shaped plates are pushed by the connecting rod, causing the first and second arc-shaped plates to rotate relative to each other and form a flux box. This can effectively reduce the time required for flux box installation and improve the efficiency of reinforcing bar welding to a certain extent.

[0018] 2. The electroslag pressure welding device and construction method for shear wall construction of the present invention uses a first top pressure rod to drive the control plate to slide towards the reinforcing bar. The first and second magnets make the movement of the control plate and the moving block synchronized. Therefore, when the control plate controls the combination of the first arc plate and the second arc plate through the connecting rod, the moving block will be located on the right side of the feeding trough. At this time, the feeding pipe will synchronously deliver a certain amount of flux into the flux box. The operation is simple and smooth, improving the efficiency of reinforcing bar welding.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 7 As shown in the embodiment of the present invention, an electroslag pressure welding device for shear wall construction includes a welding machine 1, an operation box 2, and a flux box composed of a first arc plate 25 and a second arc plate 26. A first mounting base 3 is slidably installed below the operation box 2. A first positioning handle 11 for placing the upper rebar is fixedly installed on the first mounting base 3. A first mounting box 4 is fixedly installed on the first mounting base 3. A first pressing rod 5 for pressing the upper rebar is threadedly connected inside the first mounting box 4. The upper reinforcing bar can be placed inside the first positioning handle 11. Then, by rotating the first pressing rod 5, the first pressing rod 5 slides toward the upper reinforcing bar inside the first positioning handle 11 until the first pressing rod 5 presses against the upper reinforcing bar. At this time, the upper reinforcing bar will be fixed on the first positioning handle 11.

[0024] A second mounting base 7 is provided below the first mounting base 3. A second positioning handle 12 for placing the lower rebar is fixedly installed on the second mounting base 7. A second mounting box 9 is fixedly installed on the second mounting base 7. A second pressing rod 10 for pressing down the lower rebar is threadedly connected inside the second mounting box 9. The second mounting base 7 coincides with the central axis of the first mounting base 3. The second positioning handle 12 is placed on the lower reinforcing bar. Then, by controlling the rotation of the second pressing rod 10, the second pressing rod 10 moves towards the lower reinforcing bar until the second pressing rod 10 presses against the lower reinforcing bar. At this time, the lower reinforcing bar can be fixed inside the second positioning handle 12. Since the first mounting base 3 is located below the operating box 2, and the center of the second mounting base 7 coincides with that of the first mounting base 3, when the upper reinforcing bar is fixed inside the first positioning handle 11 and the lower reinforcing bar is fixed inside the second positioning handle 12, the axes of the upper and lower reinforcing bars will coincide, which is used to improve the accuracy of welding the upper and lower reinforcing bars.

[0025] A collection box 18 is fixedly installed on the second mounting base 7, and a guide platform 17 is provided below the flux box. The other end of the guide platform 17 extends into the interior of the collection box 18. The guide platform 17 is tilted toward the collection box 18. When the first arc plate 25 and the second arc plate 26 are opened, the flux inside will fall onto the guide platform 17. Since the guide platform 17 is tilted, the flux falling onto the guide platform 17 will enter the collection box 18. A filter screen can be installed inside the collection box 18 to filter out the iron slag in the flux.

[0026] A material platform 16 is fixedly installed on the operation box 2. A conveying pipe 24 is provided between the material platform 16 and the collection box 18. A feeding pipe 23 is provided at the bottom of the material platform 16, and one end of the feeding pipe 23 extends into the inside of the flux box.

[0027] The top of the material platform 16 is provided with a material inlet, which can be used to add flux. The flux in the material platform 16 can be transported to the inside of the flux box through the feeding pipe 23, which facilitates the welding of the upper and lower steel bars.

[0028] The conveying pipe 24 is equipped with a spiral auger to transport the flux in the collection box 18 to the material platform 16, which can quickly and conveniently utilize the recovered flux. The spiral auger can be controlled by a power motor.

[0029] In a preferred embodiment of the present invention, a threaded rod 13 is rotatably mounted inside the operation 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 mounted on the second mounting seat 7, and one end of the threaded rod 13 extends into the inside of the sleeve 8.

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

[0031] In a preferred embodiment of the present invention, a worm gear 14 is fixedly installed at the top of the threaded rod 13, and a worm 15 is rotatably installed 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 gear 14 meshes with the worm 15.

[0032] Rotating the worm gear 15 drives the worm wheel 14 to rotate, and the rotation of the worm wheel 14 drives the threaded rod 13 to rotate, thereby controlling the movement of the first mounting base 3.

[0033] In a preferred embodiment of the present invention, a sliding cylinder 6 is provided on the sleeve 8, and a control plate 19 is fixedly installed 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 cylinder, which is the flux cylinder. When the first arc plate 25 and the second arc plate 26 are opened, the flux inside the flux cylinder will fall out.

[0034] The sliding cylinder 6 is a telescopic cylinder. By setting the sliding cylinder 6, the control plate 19 can only move horizontally and cannot move vertically.

[0035] The first pressing rod 5 passes through the control plate 19. A limit piece is provided on the first pressing rod 5. The position of the control plate 19 and the first pressing rod 5 can be bound by the limit piece. When the first pressing rod 5 slides, it will drive the control plate 19 to slide synchronously. A sliding groove is provided on the first pressing rod 5 for the first pressing rod 5 to slide up and down in the control plate 19. When the first mounting base 3 slides, it will drive the first pressing rod 5 to slide in the sliding groove without affecting the movement of the control plate 19.

[0036] When the first top pressure rod 5 drives the control plate 19 to slide towards the direction of the reinforcing 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 top pressure rod 5 drives the control plate 19 to slide away from the reinforcing bar, the connecting rod 21 will separate the first arc plate 25 from the second arc plate 26. It should be noted that the top of the first arc plate 25 and the second arc plate 26 are in contact with the bottom of the first positioning handle 11 after the upper reinforcing bar is welded down.

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

[0039] Both the first baffle 39 and the second baffle 40 are arc-shaped plates used to seal the bottom of the first arc-shaped plate 25 and the second arc-shaped plate 26, preventing flux from falling. When the first arc-shaped plate 25 and the second arc-shaped plate 26 rotate relative to each other and form a flux box, the first baffle 39 and the second baffle 40 also form a blocking plate. A blocking cloth is set at the center of the first baffle 39 and the second baffle 40 to seal the gap between the first baffle 39 and the second baffle 40 and the reinforcing bar. By controlling the pressure rod 27 inside the first baffle 39 and the second baffle 40 to slide towards the reinforcing bar, the blocking cloth will be pressed down, which can effectively reduce the gap between the baffle 39 and the reinforcing bar and reduce the falling flux.

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

[0041] When the first pressing rod 5 drives the control plate 19 to slide towards the first arc plate 25 and the second arc 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 pressing rod 27 through the inclined surface of the inner wall, causing the pressing rod 27 to move towards the steel bar, which will press the blocking cloth to contact the steel bar and reduce the gap. At this time, the reset spring set on the outer wall of the pressing 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 pressing rod 27 that is not being pressed will be reset under the action of the reset spring, releasing the pressing on the blocking cloth.

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

[0043] The internal structure of the second arc-shaped plate 26 is the same as that of the first arc-shaped plate 25.

[0044] In a preferred embodiment of the present invention, a placement tube 32 is fixedly installed inside the material platform 16, an inlet 33 is opened at the top of the placement tube 32, a pusher block 34 is slidably installed inside the placement tube 32, a feeding groove 38 is opened at the bottom of the material platform 16, and one end of the feeding tube 23 is connected to the feeding groove 38.

[0045] When the push block 34 is located at the leftmost position of the placement tube 32, there is a space between the push block 34 and the inlet 33. Therefore, the flux inside the material table 16 will enter the interior of the placement tube 32 through this space, and then the flux inside the placement tube 32 will be sent into the interior of the feeding tube 23 through the feeding groove 38.

[0046] When the pusher block 34 slides to the right inside the placement tube 32 and blocks the inlet 33, the flux in the material platform 16 cannot enter the placement tube 32, and therefore cannot be conveyed to the flux box through the feeding pipe 23.

[0047] In a preferred embodiment of the present invention, the push block 34 is fixedly connected to the moving block 35 by a connecting rod. The bottom end of the moving block 35 is provided with a first magnet. The top end of the control plate 19 is fixedly installed with a second magnet 20 for attracting the first magnet. The bottom end of the moving block 35 is provided with a connecting groove 37, which is connected to the feeding groove 38. A guide plate 36 is provided between the push block 34 and the moving block 35. The top end of the guide plate 36 is inclined.

[0048] When the push 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 push block 34 is located at the leftmost position of the placement tube 32, the moving block 35 is located on the left side of the feeding trough 38. The flux in the material table 16 can enter the interior of the placement tube 32 through the inlet 33 and be transported to the connecting trough 37 by 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 trough 37 will enter the interior of the feeding tube 23 through the feeding trough 38 and finally enter the flux box.

[0050] The first magnet box and the second magnet 20 can synchronize the movement of the control board 19 and the moving block 35. Therefore, when the control board 19 controls the combination of the first arc plate 25 and the second arc 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 deliver a certain amount of flux into the inside of the flux box. The operation is simple and smooth, which improves the efficiency of steel bar welding.

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

[0052] Working principle: Place the second positioning handle 12 on the lower reinforcing bar, and then control the rotation of the second pressing rod 10 to move it towards the lower reinforcing bar until it presses against it. At this point, the lower reinforcing bar can be fixed on the second positioning handle 12. Then, rotate the first pressing rod 5 to slide it towards the upper reinforcing bar inside the first positioning handle 11 until it presses against it. The upper reinforcing bar will then be fixed on the first positioning handle 11. When the first pressing rod 5 drives the control plate 19 to slide towards the reinforcing bar, the control plate 19 will push the first arc plate 25 and the second arc plate 26 through the connecting rod 21, causing them to rotate relative to each other and form a flux box. This can effectively reduce the time required for flux box installation and improve the efficiency of reinforcing bar welding to a certain extent.

[0053] When the first top pressure rod 5 drives the control plate 19 to slide towards the direction of the reinforcing 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 arc plate 25 and the second arc 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 deliver a certain amount of flux into the inside of the flux box. The operation is simple and smooth, improving the efficiency of reinforcing bar welding.
