Description

Technical Field

[0001] The present invention relates to the technical field of steel structure manufacturing and welding, and particularly relates to a device and method for laying rod-shaped ceramic backing for butt welds. Background Art

[0002] In on-site welding projects of steel structures in the construction industry, there are often a large number of plate butt joints that need to be welded. Currently, the single-sided welding with double-sided forming technology using ceramic backing on the back of the weld is adopted for the plate butt joints of steel structures. Since steel structure projects are mostly distributed in areas such as rivers and viaducts, generally an aerial work operation platform needs to be erected for the butt welds with ceramic backing on the back. This not only has a long operation process, low efficiency, high cost, and high risk, but also has an adverse impact on personnel safety and the ecological environment.

[0003] Patent document CN217045121U discloses a protective magnetic backing sticker for high-altitude steel structure welding, including a flame-retardant layer and a fireproof layer. The fireproof layer is connected below the flame-retardant layer. A ceramic backing installation groove for installing a ceramic backing is reserved in the middle of the flame-retardant layer. A magnetic attraction member for enabling the whole protective magnetic backing sticker to be adsorbed below the steel member to be welded is also arranged on the flame-retardant layer. The protective magnetic backing sticker for high-altitude steel structure welding of the present utility model has a simple structure and is convenient to be connected below the steel member to be welded during use. During use, through the magnetic connection method, the ceramic backing is exactly located below the weld of the steel member to be welded and completely covers the weld of the steel member to be welded. Therefore, there is no leakage of sparks, no welding molten iron flowing down to the ground, and no ceramic backing blocks falling to the ground. Moreover, the installation and removal are flexible, and the magnetism is safe, reliable, and lasting. However, this installation method is too cumbersome to continuously lay the ceramic backing.

[0004] Patent document CN215393365U discloses a reinforcing device for a ceramic backing for single-sided welding with double-sided forming welds, including a steel strip and a plurality of magnets. The steel strip has grooves. The steel strip is arranged below the ceramic backing and the steel base material, and the ceramic backing is located in the grooves, and is in contact with the ceramic backing through the bottom and side walls of the grooves to keep the ceramic backing from displacement. The plurality of magnets are arranged on both sides of the steel strip, and the end of the steel strip is connected and fixed to the lower end surface of the steel base material through the plurality of magnets. This reinforcing device improves the forming quality of the back of the weld and also improves the fatigue resistance of the weld. At the same time, a large amount of post-welding trimming and grinding work is reduced, the labor intensity is lowered, which is beneficial to the health of construction workers and reduces environmental pollution. Similarly, the installation method is too cumbersome to continuously lay the ceramic backing.

[0005] Patent document CN108176910A discloses fixing the ceramic backing through aluminum parts. The installation method is too cumbersome and costly, and the ceramic backing cannot be continuously laid.

[0006] Therefore, the current focus is on developing a ceramic pad laying device and process that not only has a short operation process, high efficiency, low cost, but also ensures personnel safety. Summary of the Invention

[0014] Further, the width of the wheel surface of the pressing roller 1 is greater than or equal to the width of the ceramic backing.

[0015] Further, the linkage rod 2 is in a hook-like structure. One end of the hook-like structure is connected to the rotating shaft 5, and the other end is connected to the pressing roller 1.

[0016] A method for using the above-mentioned semi-automatic laying device for high-altitude ceramic backing is also provided, which is characterized by including the following steps:

[0017] Step 1: Fix the starting end of the backing at the weld end, and extend the linkage rod 2 through the weld to the back of the weld of the box girder bottom plate or top plate;

[0018] Step 2: Twist the knob 7 at the B end of the operating rod to drive the operating rod 6 to the traction line 8 of the linkage rod 2, and pull the pressing roller 1 at the end of the linkage rod 2 to rotate horizontally, and adjust the pressing roller 1 to the correct traveling direction;

[0019] Step 3: Apply a downward pressure at the B end of the operating rod 6, and pry the linkage rod 2 upward through the rotating shaft 5, so that the pressing roller 1 at the end of the linkage rod is pressed against and tightened with the starting end of the ceramic backing, and ensure that the ceramic backing is facing correctly;

[0020] Step 4: Pull the operating rod 6, pull the bearing at the rotating shaft 5 to rotate, pull the connecting rod 4 to move the roller 3, drive the whole device to move forward, drive the pressing roller 1 to roll forward under the condition of tightly pressing the backing, and ensure that the ceramic backing is closely attached to the back of the steel plate.

[0021] Step 5: After the laying is completed, pull the device to the weld end, apply a downward force at the end of the operating rod, pry the end of the linkage rod out of the weld, and remove the device.

[0022] The present invention has the following beneficial effects compared with the prior art:

[0023] 1. Connect the operating rods before and after with a rotating shaft, and adjust the pressing roller to press the ceramic backing through the rotating shaft, which is convenient and fast.

[0024] 2. The laying of the backing can be carried out from the inside or on the top plate of the box girder, greatly reducing the risks that may be brought by the installation construction platform.
