Description

Technical Field

[0001] The invention relates to the technical field of reinforcement of steel bar frames, in particular to a reinforced concrete frame reinforcement welding and fixing device. Background Art

[0002] The reinforced frame is the core supporting structure in modern buildings, bridges, roads and other projects. It is composed of steel bars, concrete and connectors, and forms a stable and solid overall frame through components such as beams and columns. It is characterized by good supporting function, seismic resistance, flexible spatial layout adaptability and durability. It can withstand various external loads such as gravity, wind force, and earthquake force to ensure the safety and stability of the structure. Due to various factors such as design calculation errors, non-standard construction, substandard material quality, long-term environmental corrosion and load changes, the reinforced frame used for pouring concrete may have defects such as insufficient strength, weld cracking, steel corrosion or cross-section weakening. These defects will reduce the bearing capacity and stability of the structure, seriously threatening the safety of the building. In order to repair these defects and improve the overall performance of the structure, effective reinforcement methods need to be adopted. Electroslag pressure welding, as an efficient and economical connection method, plays an important role in the reinforcement of reinforced frames. Through the action of arc heat and resistance heat, electroslag pressure welding can melt the ends of the steel bars and form a solid joint, thereby improving the connection strength and overall stability of the reinforced frame.

[0003] During the electroslag pressure welding process, the first step in the welding operation is to accurately ensure that the upper steel bar is aligned with the lower steel bar, and then lift the upper steel bar. This action is intended to smoothly introduce the welding flux into the gap between the two steel bars. Next, start the welding machine to heat the end of the lower steel bar in the welding cup to a molten state, and finally insert the upper steel bar into the lower steel bar through a fixing device. Although this operation is usually assisted by a certain device, due to differences in human reaction speed, judgment ability and operating skills, it is difficult to ensure that the insertion depth can be accurately controlled each time the operation is performed. Especially in continuous operation or fatigue status, the operating error may be further increased, thereby affecting the effect of welding reinforcement. For this reason, we propose a reinforced concrete frame reinforcement welding fixture. Summary of the invention

Detailed implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figures 1-8 , the present invention provides a technical solution: a reinforced concrete frame reinforcement welding fixing device, including a fixed frame 1, a moving seat 2 and a clamping seat 3, and the moving seat 2 is slidably connected to the fixed frame 1. It also includes an acceleration magnet 4, and the acceleration magnet 4 is located on the fixed frame 1.

[0031] A disassembly mechanism 5, the disassembly mechanism 5 is located on the fixed frame 1, and after the reinforcement welding of the steel bar frame is completed, the fixed frame 1 and the moving seat 2 are separated from the clamping seat 3 through the disassembly mechanism 5.

[0032] The advantage of the splitting mechanism 5 is that after welding is completed, the fixing bracket 1 can be directly separated from the clamping seat 3, enabling the clamping seat 3 to still fix the steel bar, while the fixing bracket 1 can be connected to a new clamping seat 3 to continue the welding work. This design allows for the preparation of the next steel bar for welding immediately after welding one steel bar, reducing waiting time. The quick replacement of the fixing clamp and the clamping seat 3 makes the welding process smoother, improving the overall work efficiency and the utilization rate of the equipment, enabling the welding equipment to maintain a high-efficiency working state for a longer time. Moreover, the separation design of the fixing clamp and the clamping seat 3 enables the welding equipment to more flexibly adapt to various welding requirements.

[0033] The docking drive unit 8 is arranged on the fixing bracket 1, and the acceleration magnet 4 is arranged on the docking drive unit 8. When welding a steel bar framework, the docking drive unit 8 drives the upper steel bar fixed by the clamping seat 3 connected to the moving seat 2 to be inserted into the lower steel bar that is already in a molten state, and the acceleration magnet 4 accelerates the insertion speed of the upper steel bar.

[0034] The advantage of the docking drive unit 8 is that through the energy storage and release mechanism, it realizes the delicate control of the descent of the upper steel bar. At the same time, with the help of the magnet's boosting function, it ensures that the upper steel bar accurately inserts into the lower steel bar at a faster speed after contacting the molten pool and maintains a consistent penetration distance. The energy storage and release of the docking drive unit 8 can precisely control the descent speed and force of the upper steel bar, avoiding welding defects caused by too fast or too slow speed. The acceleration effect of the magnet further improves the accuracy of the insertion speed, ensuring the stability and reliability of the welding process. Precisely controlling the steel bar insertion distance helps reduce welding defects such as uneven welds and lack of fusion, thereby improving the welding quality. At the same time, the acceleration effect of the magnet can ensure more complete fusion between the upper steel bar and the lower steel bar, improving the strength and toughness of the welding joint.

[0035] The splitting mechanism 5 includes an assembly 6 arranged on the fixing bracket 1. Through the assembly 6, the clamping seat 3 is combined and connected to the fixing bracket 1 and the moving seat 2. A locking member 7 is arranged on the assembly 6, and the locking member 7 is used to fix the clamping seat 3.

[0036] The assembly 6 includes a combined groove 61 formed on the fixed frame 1 and the movable seat 2. A docking plate 62 is provided on the clamping seat 3. The docking plate 62 is slidably connected to the combined groove 61. A synchronous lead screw 63 is provided on the clamping seat 3. The synchronous lead screw 63 is threadedly connected to the clamping seat 3. Fixed blocks 64 are provided on both the movable seat 2 and the fixed frame 1. An extrusion lead screw 65 is provided on the fixed block 64. The extrusion lead screw 65 is threadedly connected to the fixed block 64. A docking groove 66 is formed at one end of the synchronous lead screw 63. A rotating rod 67 is slidably provided on the extrusion lead screw 65. The rotating rod 67 penetrates through the extrusion lead screw 65. A clamping block 68 for cooperating with the docking groove 66 is provided at one end of the rotating rod 67. A buffer spring 69 is sleeved on the rotating rod 67 between the clamping block 68 and the extrusion lead screw 65. A control plate 610 is rotatably provided at one end of the rotating rod 67 away from the clamping block 68. An expansion rod 611 is provided between multiple clamping seats 3, and the diameter of the extrusion lead screw 65 is smaller than that of the synchronous lead screw 63.

[0037] The advantage of the assembly 6 is that it can quickly disassemble and assemble the fixed frame 1, the movable seat 2 and the clamping seat 3. The design of quick disassembly and assembly significantly shortens the time required to replace the clamping seat 3, thereby improving the operation efficiency of the entire welding process, reducing the time interrupted due to equipment replacement, enabling the welding operation to be carried out more continuously and efficiently, and at the same time allowing the preparation for welding the next steel bar to start immediately after welding one steel bar, reducing the waiting time.

[0038] The locking member 7 includes a locking groove 71 formed on the docking plate 62. Locking bins 72 are provided on both the movable seat 2 and the fixed frame 1. A locking rod 73 is slidably provided on the locking bin 72. A locking block 74 for cooperating with the locking groove 71 is provided on the locking rod 73. The locking block 74 is slidably connected to the combined groove 61. An extrusion spring 75 is sleeved on one end of the locking rod 73 inside the locking bin 72.

[0039] The advantage of the locking member 7 is that it can fix the clamping seat 3, ensuring the stability of the clamped steel bar during the welding process, thereby improving the quality of the reinforcement frame reinforcement welding.

[0040] When docking the clamping seat 3, first insert the docking plate 62 on the clamping seat into the combined groove 61 on the fixed frame 1 and the movable seat 2 to make them dock. During the docking process, the staff stretches the locking rod 73 to drive the locking block 74 to move, so that the locking block 74 retracts against the elastic force of the extrusion spring 75 until the docking plate 62 completely enters the combined groove 61, and then release the locking block 74 to make it engage with the locking groove 71 on the docking plate 62. At this time, the docking of the clamping seat 3 is completed.

[0041] When driving the clamping seat 3 to clamp the steel bar, first rotate the extrusion screw rod 65 to drive the clamping block 68 on the extrusion screw rod 65 to engage with the docking groove 66 on the synchronous screw rod 63. At this time, the extrusion screw rod 65 drives the synchronous screw rod 63 to rotate together, thereby pushing the synchronous screw rod 63 to displace and clamp and fix the steel bar. When it is necessary to remove the fixing frame 1 and the moving seat 2 after welding is completed, pull the locking rod 73 and the locking block 74 to disengage the locking block 74 from the locking groove 71, and the connection between the fixing frame 1 and the moving seat 2 and the clamping plate can be released, and the operation is simple and fast.

[0042] The docking drive unit 8 includes a moving member 9 provided on the fixing frame 1, and the moving member 9 is used to drive the moving seat 2 to displace. A power storage member 10 is provided on the fixing frame 1, and the power storage member 10 is used to provide power for the upper steel bar to be inserted into the lower steel bar. A release member 11 is provided on the power storage member 10, and the release member 11 is used to release the power stored by the power storage member 10. An acceleration member 12 is provided on the fixing frame 1, and the acceleration member 12 is used to accelerate the insertion speed of the upper steel bar.

[0043] The moving member 9 includes a power storage bin 91 provided on the fixing frame 1. A drive rod 92 is rotatably provided in the power storage bin 91. One end of the drive rod 92 penetrates through the power storage bin 91. A moving screw rod 93 is provided on the drive rod 92. The moving screw rod 93 is threadedly connected to the drive rod 92. The drive rod 92 is connected to the moving seat 2. A worm gear 94 is provided at one end of the drive rod 92 located in the power storage bin 91. A worm 95 meshing with the worm gear 94 is rotatably provided in the power storage bin 91. One end of the worm 95 penetrates through the power storage bin 91.

[0044] The power storage member 10 includes a power storage bin 101 provided on the fixing frame 1. One end of the worm 95 extends into the power storage bin 101. A docking rod 102 is movably provided on the power storage bin 101. The docking rod 102 is slidably connected to the worm 95. A first power storage gear 103 is provided on the docking rod 102. A rotating shaft 104 is rotatably provided in the power storage bin 101. A spring box 105 is provided in the power storage bin 101. The spring box 105 is rotatably connected to the rotating shaft 104. A spring 106 is provided in the spring box 105. One end of the spring 106 is connected to the rotating shaft 104. A second power storage gear 107 meshing with the first power storage gear 103 is provided on the rotating shaft 104, and the diameter of the first power storage gear 103 is larger than that of the second power storage gear 107.

[0045] The advantage of setting the power storage member 10 is that the descending speed and strength of the upper steel bar can be accurately controlled through power storage and release, avoiding welding defects caused by too fast or too slow speed.

[0046] The release member 11 includes a first release gear 111 provided on the docking rod 102. A second release gear 112 that cooperates with the first release gear 111 is provided on the rotating shaft 104. The diameter of the second release gear 112 is larger than that of the first release gear 111, and the first release gear 111 and the second release gear 112 do not engage during the energy storage process of the clockwork spring 106. A limiting rod 113 is provided on the energy storage chamber 101. A control plate 114 is slidably provided at the outer end of the docking rod 102 outside the energy storage chamber 101. A release groove 115 that cooperates with the limiting rod 113 is provided on the control plate 114.

[0047] The acceleration member 12 includes a mounting frame 121 provided on the fixed frame 1. A turning shaft 123 is rotatably provided in the mounting frame 121. The turning shaft 123 is connected to the mounting frame 121 in a damping manner. A turning plate 124 is provided on the turning shaft 123. The turning plate 124 is connected to the acceleration magnet 4. A turning gear 125 is provided on the turning shaft 123. A control rod 126 is provided on the moving seat 2. Control teeth 127 that engage with the turning gear 125 are provided on the control rod 126. A fixed magnet 122 that attracts the acceleration magnet 4 to each other is provided on the moving seat 2.

[0048] The advantage of providing the acceleration member 12 is that the accuracy of the insertion speed is further improved through the acceleration effect of the magnet, ensuring the stability and reliability of the welding process. Precise control of the insertion distance of the steel bars helps to reduce welding defects such as uneven welds and lack of fusion, thereby improving the welding quality. At the same time, the acceleration effect of the magnet can ensure more sufficient fusion between the upper steel bar and the lower steel bar, improving the strength and toughness of the welded joint.

[0049] After the steel bars are fixed, the staff first rotates the control plate 114 to drive the docking rod 102 to rotate. The rotation of the docking rod 102 drives the first energy storage gear 103 provided thereon to rotate. The rotation of the first energy storage gear 103 drives the second energy storage gear 107 that meshes with it to rotate. The rotation of the second energy storage gear 107 drives the rotating shaft 104 connected to it to rotate. While the rotating shaft 104 rotates, it drives the clockwork spring 106 to store energy. And because the diameter of the first energy storage gear 103 is larger than that of the second energy storage gear 107, the energy stored by the clockwork spring 106 will be greater. At the same time, the rotation of the docking rod 102 drives the worm 95 to rotate synchronously. The rotation of the worm 95 drives the worm gear 94 that meshes with it to rotate synchronously. The rotation of the worm gear 94 drives the driving rod 92 to rotate. The rotation of the driving rod 92 drives the moving lead screw 93 that is threadedly connected to it to rise. The rise of the moving lead screw 93 drives the moving seat 2 to rise synchronously, thereby driving the upper steel bar connected to the moving seat 2 to rise. After the above operations are completed, the release groove 115 on the control plate 114 is docked with the limiting rod 113, thereby realizing the fixation of the docking rod 102.

[0050] After the lower steel bar end in the welding cup melts, release the fixation of the docking rod 102 and pull the docking rod 102, so that the first energy storage gear 103 disengages from the second energy storage gear 107, while the first release gear 111 engages with the second release gear 112. At the same time, because the diameter of the second release gear 112 is larger than that of the first release gear 111, the descending distance of the moving seat 2 will be more. When the worm 95 rotates in the reverse direction, it will drive the moving seat 2 to descend synchronously. During the descent of the moving seat 2, it drives the upper steel bar to contact the molten pool generated by the melting of the lower steel bar. At the same time, the control rod 126 connected to the moving seat 2 descends synchronously and drives the flip plate 124 to flip through the control teeth 127 arranged on it, so that the acceleration magnet 4 attracts the fixed magnet 122 arranged on the moving seat 2. Because when the thrust generated by the rotation of the screw and the downward traction force are in the same direction, these two forces will be superimposed on each other to form a greater resultant force to push the moving seat 2 to descend. This power superposition effect will significantly increase the acceleration and speed of the descent of the moving seat 2, so that the upper steel bar can be quickly inserted into the lower steel bar to improve the welding reinforcement effect.

[0051] When in use, when docking and clamping the seat 3, first insert the docking plate 62 on the clamping seat into the combined groove 61 on the fixed frame 1 and the moving seat 2 to dock the two. During the docking process, the staff stretches the lock rod 73 to drive the lock block 74 to move, so that the lock block 74 retracts against the elastic force of the compression spring 75 until the docking plate 62 completely enters the combined groove 61, and then release the lock block 74 to make it engage with the lock groove 71 on the docking plate 62. At this time, the docking of the clamping seat 3 is completed.

[0052] When driving the clamping seat 3 to clamp the steel bar, first rotate the extrusion screw rod 65 to drive the clamping block 68 on the extrusion screw rod 65 to engage with the docking groove 66 on the synchronous screw rod 63. At this time, the extrusion screw rod 65 drives the synchronous screw rod 63 to rotate together, so as to push the synchronous screw rod 63 to displace to clamp and fix the steel bar. When it is necessary to remove the fixed frame 1 and the moving seat 2 after welding is completed, pull the lock rod 73 and the lock block 74 to disengage the lock block 74 from the lock groove 71 to release the connection between the fixed frame 1 and the moving seat 2 and the clamping plate.

[0053] After the steel bars are fixed, the staff first rotate the control panel 114 to drive the docking rod 102 to rotate. The rotation of the docking rod 102 drives the first energy storage gear 103 arranged on it to rotate. The rotation of the first energy storage gear 103 drives the second energy storage gear 107 meshing with it to rotate. The rotation of the second energy storage gear 107 drives the rotating shaft 104 connected to it to rotate. While the rotating shaft 104 rotates, it drives the clockwork spring 106 to store energy. And because the diameter of the first energy storage gear 103 is larger than that of the second energy storage gear 107, the energy stored in the clockwork spring 106 will be greater. At the same time, the rotation of the docking rod 102 drives the worm 95 to rotate synchronously. The rotation of the worm 95 drives the worm gear 94 meshing with it to rotate synchronously. The rotation of the worm gear 94 drives the driving rod 92 to rotate. The rotation of the driving rod 92 drives the moving lead screw 93 connected to it by threads to rise. The rising of the moving lead screw 93 drives the moving seat 2 to rise synchronously, thereby driving the upper steel bar connected to the moving seat 2 to rise. After the above operations are completed, the release groove 115 on the control panel 114 is docked with the limit rod 113, so as to fix the docking rod 102.

[0054] When the end of the lower steel bar in the welding cup melts, the fixation of the docking rod 102 is released, and the docking rod 102 is pulled to disengage the first energy storage gear 103 from the second energy storage gear 107, while the first release gear 111 meshes with the second release gear 112. At the same time, because the diameter of the second release gear 112 is larger than that of the first release gear 111, the descending distance of the moving seat 2 will be more. When the worm 95 rotates in the reverse direction, it will drive the moving seat 2 to descend synchronously. During the descending process of the moving seat 2, it drives the upper steel bar to contact the molten pool generated by the melting of the lower steel bar. At the same time, the control rod 126 connected to the moving seat 2 descends synchronously and drives the turning plate 124 to turn through the control teeth 127 arranged on it, so that the accelerating magnet 4 attracts the fixed magnet 122 arranged on the moving seat 2. Because when the thrust generated by the rotation of the screw and the downward traction force are in the same direction, these two forces will be superimposed on each other to form a greater resultant force to push the moving seat 2 to descend. This dynamic superposition effect will significantly increase the acceleration and speed of the descending of the moving seat 2, so that the upper steel bar can be quickly inserted into the lower steel bar.

[0055] Embodiment 2: Please refer to Figure 9 , the present invention provides a technical solution: a progress mark 13 is arranged on the fixing frame 1. The setting of the progress mark 13 enables the staff to more intuitively penetrate the moving distance of the steel bars.
