Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge high pier welding construction, in particular to a bridge high pier welding construction device. BACKGROUND

[0002] Bridge high pier generally refers to a columnar support component with a large height used for supporting the upper structure of a bridge, and high pier welding is mainly applied to the connection of vertical steel bars, middle beam and U-shaped rib plates, etc., wherein the high pier vertical steel bars are generally welded efficiently through electroslag pressure welding.

[0003] In the prior art, when the vertical steel bars are subjected to electroslag pressure welding, the two steel bars are first manually aligned along the vertical direction to ensure that they are in a concentric butt joint state, then the upper and lower steel bars are clamped and fixed by clamping workpieces to maintain the stability of the butt joint position, then a flux box is installed at the butt joint of the steel bars, and the flux box is filled with flux through a filler hopper so that the butt joint ends of the steel bars are completely buried in the flux, wherein, in order to prevent leakage of the flux, a piece of asbestos cloth is sometimes sealed around the bottom of the flux box, then power is supplied to make the welding current flow through the gap between the two steel bars, the flux is melted by resistance heat, and the process goes through an electric arc process and an electroslag process in turn, so that the steel bar ends are rapidly melted by high temperature, and finally the molten metal is gradually fused by applying pressure to the upper steel bar, thereby completing the butt welding of the vertical steel bars.

[0004] However, the conventional electroslag pressure welding of vertical steel bars has the following problems: 1. In the prior art, since the butt joint ends of the two steel bars need to be installed with a flux box and the filled flux needs to directly contact the butt joint ends of the steel bars, the existing butt joint ends of the steel bars usually do not integrate a guide centering structure with a positioning function, resulting in a lack of mechanical auxiliary limiting during the installation of the steel bar butt joint, thereby highly relying on the experience and visual judgment of the operator, which makes it more likely for the steel bar butt joint installation process to have a certain axis deviation or included angle, not only affecting the stability of the electric arc and the uniformity of the electroslag heat distribution during the welding process, reducing the fusion quality and the reliability of the mechanical properties of the joint area, but also further affecting the overall load-bearing performance and long-term durability of the high pier if such welding defects accumulate; 2. In the prior art, the operator must first accurately align and clamp the upper and lower steel bars before installing the flux box and filling the flux, resulting in a relatively fragmented process and a complicated process connection, and the residual flux that has not been melted in the flux box after the welding is completed is extremely likely to be scattered disorderly when the flux box is disassembled due to the lack of a guide recovery structure, causing material waste and being difficult to effectively recover, not only directly increasing the cost of flux consumables, but also possibly polluting the work environment and increasing the cleaning burden.

[0035] By fitting the arc-shaped rear end of the positioning plate 224 on the front side of the vertical steel bar 1, the assembly arc plate 222 is positioned around the front side of the vertical steel bar 1, then the cross knob 232 is rotationally driven to synchronously rotate the adjusting screw 231, the adjusting screw 231 is driven to move the assembly arc plate 233 forward by a certain distance through the screw transmission with the horizontal section of the L-shaped assembly frame 21, until the assembly arc plate 233 is positioned around the rear side of the vertical steel bar 1, so that the assembly arc plate 222 and the assembly arc plate 233 are positioned around the outside of the lower vertical steel bar 1 to form the side wall of the flux box.

[0036] Please refer to Figure 1 , Figure 4 and Figure 5 , the automatic closing assembly 24 comprises a pressing plate 241 symmetrically arranged on the front side of the assembly arc plate 233, a sliding rod 242 fixedly arranged on the rear side of the pressing plate 241 and elastically slidably connected to the assembly arc plate 233 through a spring, and a closing plate 243 fixedly arranged on the opposite side of the pressing plate 241 and fitted on the inner wall of the assembly arc plate 233.

[0038] When the welding flux box is to be clamped on the upper end of the lower vertical steel bar 1, first, the assembly arc plate one 222 is positioned around the front side of the vertical steel bar 1 through the positioning plate 224, and the rear side arc surface of the clamping arc plate one 251 is also synchronously fitted on the front side of the vertical steel bar 1, then the assembly arc plate two 233 is driven to move forward by the directional rotating cross knob one 232 to cooperate with the assembly arc plate one 222, the abutting plate 241 is in contact with the corresponding position of the rear end of the assembly arc plate one 222, with the continuous forward movement of the assembly arc plate two 233, the abutting plate 241 and the corresponding sliding rod 242 are compressed by the assembly arc plate one 222, the closing plate 243 on the abutting plate 241 is synchronously moved, until the front side arc surface of the clamping arc plate two 253 synchronously moved with the assembly arc plate two 233 and the L-shaped connecting frame 252 is fitted on the rear side of the vertical steel bar 1, and cooperates with the clamping arc plate one 251 to stably clamp and lock the upper end of the lower vertical steel bar 1, at this time, the abutting plate 241 and the sliding rod 242 are no longer compressed by the corresponding spring, and the closing plate 243 is also synchronously stopped, so that the side wall of the welding flux box is stably surrounded by the closing plate 243 cooperating with the assembly arc plate one 222 and the assembly arc plate two 233 at the butt joint end of the vertical steel bar 1, and the clamping arc plate one 251 and the clamping arc plate two 253 are cooperated to stably clamp and fix the side wall of the welding flux box, wherein the closing plate 243 can realize the self-adaptation of the corresponding volume of the welding flux box side wall according to the corresponding size of the vertical steel bar 1.

[0039] Please refer to Figure 1 , the guide mechanism 3 includes a concentric guide part 31 provided on the positioning assembly part 22 and the adjusting assembly part 23, which is used for temporarily limiting and accurately aligning the vertical steel bar 1, and the welding flux guide part 32 provided on the clamping assembly part 25 is used for cooperating with the filler hopper to guide and recover the welding flux.

[0040] Please refer to Figure 1 , Figure 5 and Figure 6 , the welding flux guide part 32 includes a U-shaped sealing plate 321 provided on the lower side of the assembly arc plate one 222 and the assembly arc plate two 233 and opening forward, the U-shaped sealing plate 321 is rotationally connected with the vertical segment of the L-shaped connecting frame 252 through the rear side left and right symmetrical support two, the U-shaped sealing plate 321 is located above the horizontal segment of the L-shaped connecting frame 252, the inner side of the U-shaped sealing plate 321 is fitted with the left and right sides of the connecting block 223 and the positioning plate 224, the inner side arc surface of the U-shaped sealing plate 321 is concentric with the front side arc surface of the clamping arc plate two 253, the spring rod 322 moving up and down is elastically and slidably provided on the clamping arc plate one 251 through the left and right symmetrical support three, and the upper end of the spring rod 322 is fixedly provided with the support block 323 fitted with the lower surface of the U-shaped sealing plate 321.

[0041] In the process of clamping and fixing the side wall of the flux box on the upper end of the vertical steel bar 1, the U-shaped sealing plate 321 is always attached to the lower end face of the assembled arc plate two 233 until the support block 323 is attached to the lower face of the U-shaped sealing plate 321, and under the elastic support of the corresponding spring rod 322, the U-shaped sealing plate 321 continues to be stably attached to the lower end face of the assembled arc plate two 233 and the assembled arc plate one 222 until the inner side arc face of the U-shaped sealing plate 321 is synchronized with the rear side of the vertical steel bar 1 and closely attached to the clamping arc plate two 253, at this time, the U-shaped sealing plate 321 can stably close the lower end of the space surrounded by the assembled arc plate one 222 and the assembled arc plate two 233 through the matching connecting block 223 and the positioning plate 224, so as to stably form the flux box containing the filled flux through the assembled arc plate one 222, the assembled arc plate two 233, the sealing plate 243, the U-shaped sealing plate 321, the connecting block 223 and the positioning plate 224.

[0042] If the diameter difference of different vertical steel bars 1 leads to that the bottom of the flux box composed of the U-shaped sealing plate 321, the connecting block 223 and the positioning plate 224 cannot be closely attached around the circumferential side of the vertical steel bar 1, the gap of the bottom of the flux box can be plugged by winding the asbestos cloth along the circumferential side of the vertical steel bar 1 in the gap between the horizontal segment of the L-shaped connecting frame 252 and the U-shaped sealing plate 321, so as to avoid the leakage of the flux filled into the flux box from the bottom of the flux box.

[0043] The above-mentioned operation mode can automatically complete the clamping of the lower side steel bar while installing the flux box, significantly simplifying the steps of steel bar clamping and flux box installation, thereby improving the work efficiency.

[0044] When the remaining flux in the flux box that is not melted is guided and recovered back to the filler hopper, the filler hopper is first placed below the U-shaped sealing plate 321 and closely attached to the front side of the vertical steel bar 1, then the front end of the U-shaped sealing plate 321 is pressed downward, the U-shaped sealing plate 321 drives the support block 323 to compress the spring rod 322 downward, the remaining flux on the rear side of the flux box is rolled forward to the filler hopper along the U-shaped sealing plate 321 which is inclined downward from the front end, while the remaining flux on the front side of the flux box falls on the U-shaped sealing plate 321 under the guidance of the symmetrical inclined surface on the upper side of the positioning plate 224, and also falls into the filler hopper under the guidance of the U-shaped sealing plate 321, at the same time, the remaining flux inside the flux box can be vibrated up and down by shaking the U-shaped sealing plate 321 up and down, so as to promote the falling and recovery of the remaining flux.

[0045] The above-mentioned operation mode can stably guide and recover the flux that is not melted back to the filler hopper after the welding is completed, realize the orderly recovery and recycling of the flux, thereby not only reducing the material waste and construction cost, but also effectively avoiding the environmental pollution caused by the falling of the flux, and simplifying the on-site cleaning process.

[0047] When the flux box is assembled and clamped on the upper end of the lower vertical steel bar 1, the lower end of the inner arc surface of the two concentric arc plates 311 on the assembly arc plate one 222 and the assembly arc plate two 233 is stably attached to the butt joint end of the lower vertical steel bar 1, and since the concentric arc plate 311 is not completely tightly clamped on the lower vertical steel bar 1, the lower end of the upper vertical steel bar 1 can be more stably inserted into the inner side of the two concentric arc plates 311, so that through the limiting guide of the concentric arc plate 311, not only the upper vertical steel bar 1 can be temporarily and stably positioned, but also the upper and lower vertical steel bars 1 can be stably and accurately concentrically butted, thereby not only improving the stability of the electric arc combustion and the electric slag process, but also being beneficial to forming a uniform and reliable welding joint, and also reducing the welding defects caused by the positioning error of the vertical steel bar 1, and enhancing the load consistency and durability of the high pier structure as a whole.
