[0002] After welding steel structures, in order to ensure the quality of welded joints and meet design requirements, welding inspection rulers are required for measurement. Welding inspection rulers are used to measure weld height, weld width, weld angle, weld surface flatness, and length and position of welded joints.

[0003] After welding steel structures, there are often impurities such as welding slag, oil stains, oxides, etc. on the welding joints. These impurities need to be removed in time before measurement, otherwise they will affect the subsequent measurement accuracy. Traditional welding inspection rulers do not have a mechanism to clean impurities such as welding slag, which means that cleaning tools are required when cleaning welding slag and other impurities.

[0016] The beneficial effects of the present invention are as follows: 1. A steel structure welding connection detection device and method described in the present invention, by sliding the slide bar, the slide bar moves with the fixed plate and sandpaper to the welding place, so that the sandpaper is exposed from the fixed frame, and the positioning ring on the surface of the slide bar is temporarily fixed in the positioning groove of the fixed frame, so that it is convenient for sandpaper to grind and remove the welding slag and other impurities at the welding place of the steel structure. When there is too much welding slag at the welding place of the steel structure, by rotating the slide bar, the fixed plate and sandpaper are rotated with the slide bar, so that the fixed plate and sandpaper are rotated 90°, and the vertical fixed plate and sandpaper are transformed into horizontal ones, so that the welding slag and other impurities on the steel structure can be removed more efficiently.

[0017] 2. A steel structure welding connection detection device and method described in the present invention, through the designed spraying assembly, the cleaning agent pre-stored in the liquid storage box enters the bottom plate through the liquid outlet pipe, and then sprays out through the holes at the bottom of the bottom plate, so that before the sandpaper contacts the welding slag, the fixed plate first squeezes and sprays the cleaning agent to the welding slag, so that the welding slag and other impurities become soft, thereby cooperating with the subsequent sandpaper to remove the welding slag. The designed auxiliary component uses the fixed plate to squeeze the elastic ball, squeezes the gas in the elastic ball into the connecting pipe, and guides the gas around through the arc guide plate in the connecting pipe, so that after the welding slag cleaning work is completed, the gas is used to quickly blow dry the residual liquid on the surface, so as to facilitate the subsequent use of the welding inspection ruler to measure the welding joint of the steel structure. The designed quick-drying mechanism can use the gas in the pressing block to assist in drying the bottom of the sandpaper, thereby preventing the cleaning liquid from damaging the sandpaper, thereby improving the utilization rate of the sandpaper. At this time, the pressing block made of non-slip material is also convenient for holding the fixed frame and the welding inspection ruler for measurement.

[0018] 3. The steel structure welding connection detection device and method described in the present invention, because the pressing block is made of flexible material, it will move with the connecting plate and the connecting rod toward the liquid storage box, and the connecting rod will move with the push plate and several bosses when moving, and the push plate and the bosses are used to stir the detergent in the liquid storage box, thereby effectively preventing the detergent from settling after a long period of non-use, resulting in poor use effect. Because the pressing block is made of elastic material, when it is not squeezed, it will reset with the connecting plate, the connecting rod and the push plate, so as not to affect the subsequent squeezing of the liquid storage box by the fixed plate.

[0019] 4. A steel structure welding connection detection device and method described in the present invention, when one end of the height gauge and the undercut depth gauge contacts the steel structure and is measured, the pressing block is pressed so that the gas in the pressing block enters the storage slot, and the filled gas is used to push the sealing plate, so that the sealing plate slides out of the storage slot with the magnetic block, and the magnetic block adsorbs the metal height gauge or undercut depth gauge, thereby temporarily fixing the height gauge or undercut depth gauge, and making it convenient for the measurement personnel to read. The second spring makes it impossible for the sealing plate to reset quickly, thereby playing a role of delayed reset, making it convenient for the staff to confirm the value after the initial reading. The structure designed above can achieve the function of quickly fixing the height gauge and the undercut depth gauge, without the need for the cumbersome and inefficient traditional knob style.

[0031] 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.

[0032] like Figures 1 to 9 As shown, a steel structure welding connection detection device according to an embodiment of the present invention comprises a welding inspection ruler 1, a height gauge 2 and a bite edge depth gauge 3 are slidably connected to the welding inspection ruler 1, and a multi-purpose ruler 4 is rotatably connected to the side of the welding inspection ruler 1 away from the height gauge 2; a cleaning mechanism 10 is provided on the side of the welding inspection ruler 1 close to the multi-purpose ruler 4, and the cleaning mechanism 10 comprises a hollow fixed frame 11 fixedly connected to the welding inspection ruler 1, a sliding rod 12 is slidably connected to the top of the fixed frame 11, a fixed plate 13 in the fixed frame 11 is fixedly installed at the bottom of the sliding rod 12, and sandpaper 14 is installed at the bottom of the fixed plate 13, a first spring 15 is fixedly installed between the fixed plate 13 and the fixed frame 11, and a pressing block 16 of an anti-slip material is fixedly installed on both sides of the fixed frame 11. A positioning assembly 19 is provided on the surface of the sliding rod 12, and the positioning assembly 19 comprises a positioning ring 191 of a flexible material fixedly sleeved on the surface of the sliding rod 12, and a positioning groove 192 is provided in the fixed frame 11.

[0033] During operation, when the welding inspection ruler 1 is used to inspect the joint 22 of the steel structure, the pressing blocks 16 on both sides of the fixed frame 11 are held tightly, so that the welding inspection ruler 1 can be conveniently taken for use. When the welding inspection ruler 1 is close to the welding part, the slide bar 12 is slid so that the slide bar 12 moves toward the welding part with the fixed plate 13 and the sandpaper 14, so that the sandpaper 14 is exposed from the fixed frame 11, and the positioning ring 191 on the surface of the slide bar 12 is temporarily fixed in the positioning groove 192 of the fixed frame 11. At this time, the slide bar 12, the fixed plate 13 and the sandpaper 14 will not be reset under the action of the first spring 15, so that the sandpaper 14 can grind and remove the welding slag and other impurities at the welding part of the steel structure. When there is too much welding slag at the welding place of the steel structure, the sliding rod 12 is rotated, and the fixing plate 13 and the sandpaper 14 are rotated with the sliding rod 12, so that the fixing plate 13 and the sandpaper 14 are rotated 90 degrees, and then the vertical fixing plate 13 and the sandpaper 14 are transformed into horizontal ones, so that the welding slag and other impurities on the steel structure can be removed more efficiently. The positioning ring 191 is used to enter the positioning groove 192, so that the fixing plate 13 is not easy to reset under the action of the first spring 15. At the same time, due to the friction between the positioning ring 191 and the positioning groove 192, the sliding rod 12 after rotation will not be affected by the first spring 15 and reset.

[0034] The above-designed structure can quickly clean the welding slag remaining on the surface when measuring the welding points of steel structures without carrying additional cleaning equipment. It is highly integrated and easy to carry and operate, which greatly improves the measurement efficiency of the measurement personnel.

[0035] A spraying assembly 17 is arranged in the fixed frame 11, and the spraying assembly 17 includes two liquid storage boxes 171 symmetrically fixedly installed in the fixed frame 11, and a liquid outlet pipe 172 connected to the interior and having a one-way valve is fixedly installed at the bottom of the liquid storage box 171, and a hollow bottom plate 173 is fixedly installed on both sides of the fixed frame 11. A plurality of holes connected to the interior are opened at the bottom of the bottom plate 173, and one end of the liquid outlet pipe 172 away from the liquid storage box 171 is connected to the interior of the bottom plate 173, and a liquid inlet pipe connected to the interior and having a one-way valve is fixedly installed on one side of the liquid storage box 171.

[0036] Specifically, an auxiliary component 18 is provided in the fixed frame 11, and the auxiliary component 18 includes a plurality of elastic balls 181 fixedly installed in the fixed frame 11. A plurality of connecting tubes 182 are fixedly installed on one side of the bottom plate 173, and one end of the connecting tube 182 is connected to the inside of the elastic ball 181. Two symmetrically arranged guide plates 183 are fixedly installed in the connecting tube 182, and the guide plates 183 are arc-shaped.

[0037] Specifically, the pressing block 16 is hollow in design and made of elastic and flexible material. A quick-drying mechanism 20 is provided at the bottom of the pressing block 16. The quick-drying mechanism 20 includes a connecting pipe 21 connected to the inside of the pressing block 16. A joint 22 is fixedly installed at one end of the connecting pipe 21. A sealing ring 23 is fixedly sleeved on the surface of the joint 22. An air jet pipe 24 made of flexible material is fixedly installed inside the fixed frame 11. One end of the air jet pipe 24 is located outside the fixed frame 11 and connected to the connecting pipe 21.

[0038] During operation, when the slide bar 12 moves with the fixed plate 13, the two sides of the fixed plate 13 will continuously squeeze the liquid storage box 171, so that the cleaning agent (which can be a water-based cleaning liquid or an alcohol solvent, selected according to actual conditions) pre-stored in the liquid storage box 171 enters the bottom plate 173 through the liquid outlet pipe 172, and then sprays out through the holes at the bottom of the bottom plate 173, so that before the sandpaper 14 contacts the welding slag, the fixed plate 13 first squeezes and sprays the cleaning agent to the welding slag, so that the welding slag and other impurities become soft, thereby cooperating with the subsequent sandpaper 14 to remove the welding slag. It should be noted that the design of the bottom plate 173 and the opening of several holes at the bottom are to increase the spraying area, so as to better remove the welding slag. And when sliding the slide bar 12, the staff's hand is holding the fixed frame 11, and no longer presses the pressing block 16.

[0039] When the fixed plate 13 with the sandpaper 14 completes the work of removing the welding slag, it will be reset to the fixed frame 11. At this time, the elastic ball 181 is squeezed by the fixed plate 13, and the gas in the elastic ball 181 is squeezed into the connecting pipe 182, and the gas is guided to the surroundings through the arc guide plate 183 in the connecting pipe 182. After the welding slag cleaning work is completed, the gas is used to quickly blow dry the residual liquid on the surface, so as to facilitate the subsequent use of the welding inspection ruler 1 to measure the welding joint 22 of the steel structure.

[0040] After the fixing plate 13 is reset to the fixing frame 11, the pressing block 16 is pressed again, and the gas in the pressing block 16 enters the air jet pipe 24 through the connecting pipe 21 and blows toward the bottom of the sandpaper 14 (one end of the connecting pipe 21 is connected to the air jet pipe 24 in the initial state, and the sealing ring 23 is used to seal and prevent air leakage). The gas in the pressing block 16 is used to assist in drying the bottom of the sandpaper 14, thereby preventing the cleaning liquid from damaging the sandpaper 14, thereby increasing the utilization rate of the sandpaper 14. At this time, the pressing block 16 made of non-slip material also facilitates holding the fixing frame 11 and the welding inspection ruler 1 for measurement.

[0041] A stirring mechanism 30 is provided in the pressing block 16, and the stirring mechanism 30 includes a connecting plate 31 fixedly connected to the inner wall of the pressing block 16, a connecting rod 32 is fixedly installed at one end of the connecting plate 31, and the end of the connecting rod 32 away from the connecting plate 31 is in the liquid storage box 171, the connecting rod 32 and the pressing block 16 and the liquid storage box 171 are all sealed and slidably connected, a push plate 33 is fixedly installed at the end of the connecting rod 32 away from the connecting plate 31, and a plurality of bosses 34 are fixedly installed on one side of the push plate 33.

[0042] During operation, when the pressing block 16 is pressed for the first time, since the pressing block 16 is made of a flexible material, it will move the connecting plate 31 and the connecting rod 32 toward the liquid storage box 171. The connecting rod 32 will move with the push plate 33 and a plurality of bosses 34 when moving, and the push plate 33 and the bosses 34 will be used to stir the detergent in the liquid storage box 171, thereby effectively preventing the detergent from settling after a long period of non-use, resulting in poor use effect. Since the pressing block 16 is made of an elastic material, when it is not squeezed, it will reset with the connecting plate 31, the connecting rod 32 and the push plate 33, thereby not affecting the subsequent squeezing of the liquid storage box 171 by the fixing plate 13.

[0043] A limiting mechanism 40 is provided in the welding inspection ruler 1. The limiting mechanism 40 includes a plurality of receiving grooves 41 provided in the welding inspection ruler 1. The interior of the receiving groove 41 is sealingly and slidingly connected with a sealing plate 42 via a second spring 44. A magnetic block 43 is fixedly mounted on one end of the sealing plate 42. A docking tube 45 connected to the interior of the receiving groove 41 is installed on one side of the welding inspection ruler 1. One end of the docking tube 45 is connected to the connecting pipe 21. The height gauge 2 and the undercut depth gauge 3 are both made of metal.

[0044] Specifically, a limit plate 46 is fixedly installed in the storage groove 41, the cylinder on the sealing plate 42 is slidably connected to the limit plate 46, and a rubber bump 47 is fixedly installed on one side of the sealing plate 42. The bump 47 gradually increases from the end close to the sealing plate 42 to the end away from the sealing plate 42, and a groove 48 matching the bump 47 is opened on one side of the limit plate 46.

[0045] During operation, after the welding slag removal work is completed, when the welding inspection ruler 1 is used for measurement, the connecting tube 21 and the air injection tube 24 are pulled out and separated, and the two connecting tubes 21 are respectively inserted into the corresponding butt joint tubes 45, so that the gas generated after pressing the pressing block 16 again will enter the storage groove 41 through the connecting tube 21 and the butt joint tube 45. When one end of the height gauge 2 and the undercut depth gauge 3 are in contact with the steel structure and measured, it is necessary to temporarily fix the depth gauge and the undercut depth gauge 3, so as to facilitate the measurement personnel to read accurately. At this time, the pressing block 16 is pressed, so that the gas in the pressing block 16 enters the storage groove 41 (the gas will only enter the interval of the second spring 44 of the storage groove 41), and the sealing plate 42 is pushed by the filled gas, so that the sealing plate 42 slides out of the storage groove 41 with the magnetic block 43, and the magnetic block 43 is adsorbed with the metal height gauge 2 or the undercut depth gauge 3, thereby temporarily fixing the height gauge 2 or the undercut depth gauge 3, and then facilitating the measurement personnel to read.

[0046] When the pressing block 16 is released, the gas in the receiving groove 41 will flow back into the pressing block 16, and the second spring 44 will also reset the sealing plate 42, the protrusion 47 and the magnetic block 43 (when the sealing plate 42 slides toward the limit plate 46, the protrusion 47 is stuck in the groove 48). The second spring 44 cannot quickly reset the sealing plate 42, and will slowly remove the protrusion 47 on the sealing plate 42 from the groove 48, thereby delaying the reset and making it easier for the staff to confirm the value after the initial reading. The structure designed above can achieve the function of quickly fixing the height gauge 2 and the undercut depth gauge 3, without the need for the cumbersome and inefficient traditional knob style.

[0047] A detection method using the above steel structure welding connection detection device comprises the following steps: S1: Slide the slide bar 12 so that the slide bar 12 moves with the fixing plate 13 and the sandpaper 14 toward the welding position, and the positioning ring 191 on the surface of the slide bar 12 is temporarily fixed in the positioning groove 192 of the fixing frame 11, and the sandpaper 14 contacts the welding position of the steel structure, and rotate the slide bar 12 to rotate with the fixing plate 13 and the sandpaper 14, so that the fixing plate 13 and the sandpaper 14 are rotated 90 degrees and then contact the welding position of the steel structure; S2: When the slide bar moves, it brings the fixed plate 13 to continuously squeeze the liquid storage box 171, so that the cleaning agent pre-stored in the liquid storage box 171 enters the bottom plate 173 through the liquid outlet pipe 172, and then sprays out through the holes at the bottom of the bottom plate 173; S3: When the welding inspection ruler 1 is used for measurement, the gas in the pressing block 16 enters the receiving groove 41 and pushes the sealing plate 42 , so that the sealing plate 42 slides out of the receiving groove 41 with the magnetic block 43 .

[0048] Working principle: When the welding inspection ruler 1 is used to inspect the joint 22 of the steel structure, the pressing blocks 16 on both sides of the fixed frame 11 are held tightly to facilitate the use of the welding inspection ruler 1. When the welding inspection ruler 1 is close to the welding part, the slide bar 12 is slid to move the slide bar 12 with the fixed plate 13 and the sandpaper 14 toward the welding part, so that the sandpaper 14 is exposed from the fixed frame 11, and the positioning ring 191 on the surface of the slide bar 12 is temporarily fixed in the positioning groove 192 of the fixed frame 11. At this time, the slide bar 12, the fixed plate 13 and the sandpaper 14 will not be reset under the action of the first spring 15, so that the sandpaper 14 can grind and remove the welding slag and other impurities at the welding part of the steel structure. When there is too much welding slag at the welding place of the steel structure, the sliding rod 12 is rotated, and the fixing plate 13 and the sandpaper 14 are rotated with the sliding rod 12, so that the fixing plate 13 and the sandpaper 14 are rotated 90 degrees, and then the vertical fixing plate 13 and the sandpaper 14 are transformed into horizontal ones, so that the welding slag and other impurities on the steel structure can be removed more efficiently. The positioning ring 191 is used to enter the positioning groove 192, so that the fixing plate 13 is not easy to reset under the action of the first spring 15. At the same time, due to the friction between the positioning ring 191 and the positioning groove 192, the sliding rod 12 after rotation will not be affected by the first spring 15 and reset.

[0049] When the slide bar 12 moves with the fixed plate 13, the two sides of the fixed plate 13 will continuously squeeze the liquid storage box 171, so that the cleaning agent pre-stored in the liquid storage box 171 enters the bottom plate 173 through the liquid outlet pipe 172, and then sprays out through the holes at the bottom of the bottom plate 173, so that before the sandpaper 14 contacts the welding slag, the fixed plate 13 first squeezes and sprays the cleaning agent to the welding slag, so that the welding slag and other impurities become soft, so as to cooperate with the subsequent sandpaper 14 to remove the welding slag. When the fixed plate 13 and the sandpaper 14 complete the work of removing the welding slag, it will return to the fixed frame 11, and at this time, the fixed plate 13 is used to squeeze the elastic ball 181, so that the gas in the elastic ball 181 is squeezed into the connecting pipe 182, and the gas is guided to the surroundings through the arc guide plate 183 in the connecting pipe 182. After the fixing plate 13 is reset to the fixing frame 11 , the pressing block 16 is pressed again, and the gas in the pressing block 16 enters the air injection pipe 24 through the connecting pipe 21 and blows toward the bottom surface of the sandpaper 14 , thereby using the gas in the pressing block 16 to assist in drying the bottom of the sandpaper 14 .

[0050] When the pressing block 16 is pressed for the first time, since the pressing block 16 is made of a flexible material, it will move the connecting plate 31 and the connecting rod 32 toward the liquid storage box 171. The connecting rod 32 will move with the push plate 33 and several bosses 34 when moving, and the push plate 33 and the bosses 34 will be used to stir the detergent in the liquid storage box 171, thereby effectively preventing the detergent from settling after a long period of non-use, resulting in poor use effect. Since the pressing block 16 is made of an elastic material, when it is not squeezed, it will reset with the connecting plate 31, the connecting rod 32 and the push plate 33, thereby not affecting the subsequent squeezing of the liquid storage box 171 by the fixing plate 13.

[0051] After the welding slag removal work is completed, when the welding inspection ruler 1 is used for measurement, the connecting tube 21 and the air injection tube 24 are pulled out and separated, and the two connecting tubes 21 are respectively inserted into the corresponding butt joint tubes 45, so that the gas generated after pressing the pressing block 16 again will enter the storage groove 41 through the connecting tube 21 and the butt joint tube 45. When one end of the height gauge 2 and the undercut depth gauge 3 are in contact with the steel structure and measured, it is necessary to temporarily fix the depth gauge and the undercut depth gauge 3, so as to facilitate the measurement personnel to take accurate readings. At this time, the pressing block 16 is pressed, so that the gas in the pressing block 16 enters the storage groove 41, and the sealing plate 42 is pushed by the filled gas, so that the sealing plate 42 slides out of the storage groove 41 with the magnetic block 43, and the magnetic block 43 is adsorbed with the metal height gauge 2 or the undercut depth gauge 3, thereby temporarily fixing the height gauge 2 or the undercut depth gauge 3, and then facilitating the measurement personnel to take readings. When the pressing block 16 is released, the gas in the receiving groove 41 will flow back into the pressing block 16, and the second spring 44 will also bring the sealing plate 42, the protrusion 47 and the magnetic block 43 back to the original position. The second spring 44 cannot quickly bring the sealing plate 42 back to the original position, but will slowly bring the protrusion 47 on the sealing plate 42 out of the groove 48, thereby playing a role of delayed reset, which is convenient for the staff to confirm the value after the initial reading.
