Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a steel structure welding detection device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates.

[0003] After welding, the steel structure needs to be inspected to ensure the overall quality of the project. Most of the current welding inspection equipment only inspects the quality of the welds, but cannot detect whether the steel structure as a whole has deformed. When the welded steel structure is bent, it will affect the overall construction quality. Therefore, it is particularly important to design a simple and convenient device that can detect the flatness of the welded steel structure. Utility Model Content

[0004] In response to the technical problems in the prior art, the utility model provides a steel structure welding detection equipment, including a workbench and a fixture for placing a steel structure to be detected, a plurality of the fixtures are installed on the workbench at intervals, and a gap space for placing a weld is provided between two fixtures near the middle, and the detection mechanism also includes a first lifting assembly, a second lifting assembly, a pressure switch and an alarm, the two first lifting assemblies are fixedly connected to the workbench and are respectively located on both sides of the gap space, the two second lifting assemblies are slidably connected to the workbench and are respectively located at one end of the steel structure to be detected away from the gap space, a pressure switch is installed on the top of the first lifting assembly and the second lifting assembly, the pressure switch moves close to or away from the steel structure to be detected under the drive of the first lifting assembly or the second lifting assembly, the alarm is installed on the workbench and is located on both sides of the fixture, the pressure switch and the alarm are connected one-to-one, when the pressure switch contacts the steel structure to be detected, the pressure switch is closed and the alarm sounds an alarm, otherwise the alarm does not sound an alarm.

[0005] Furthermore, the detection mechanism also includes a projection plate and a laser emitter. The projection plate is fixedly installed on the workbench and is parallel to and spaced apart from the steel structure to be detected. The laser emitter corresponds one-to-one to the pressure switch. The laser emitter is installed on the top of the first lifting assembly and the second lifting assembly and is located on the side close to the projection plate. The emission port of the laser emitter is horizontally set and directly opposite to the projection plate. The height of the laser emitter is not higher than the height of the pressure switch.

[0006] Furthermore, a scale dimension line is provided on the projection plate in the vertical direction, and the length of the scale dimension line in the horizontal direction is not less than the length of the steel structure to be detected.

[0007] Furthermore, the tops of the first lifting assembly and the second lifting assembly are each provided with a plurality of limit assemblies, and the plurality of limit assemblies are evenly distributed on the edge of the pressure switch. The limit assemblies include a connecting column and an elastic pressure plate. The connecting column is fixedly installed on the tops of the first lifting assembly and the second lifting assembly, and the elastic pressure plate is fixedly installed on the tops of the connecting column. When the elastic pressure plate is not compressed, the top of the elastic pressure plate is higher than the top of the pressure switch.

[0008] Furthermore, the alarm includes a sound alarm and a light alarm.

[0009] Beneficial effects:

[0010] 1. The present invention is provided with a detection mechanism including two first lifting assemblies, two second lifting assemblies, a pressure switch and an alarm. It is possible to confirm whether the two sides of the weld of the steel structure to be inspected are in the same plane according to the alarm status of the alarms at different positions, thereby confirming whether the steel structure as a whole has been deformed, and then confirming whether the welding quality meets the standards. Specifically, when in use, the steel structure to be inspected, such as a steel pipe, steel column or steel plate, is first effectively fixed by a clamp to ensure that the weld is located in the gap space. Then, according to the length of the steel structure to be inspected, the two second lifting assemblies are respectively slid to the other end of the steel structure to be inspected, ensuring that both ends of the steel structure on each side of the weld contain a first lifting assembly and a second lifting assembly. Then, the first lifting assembly and the second lifting assembly are controlled to rise, so that the pressure switch moves toward the steel structure to be inspected until it contacts the steel structure to be inspected, and the alarm is turned off. At this time, if the height difference between the two first lifting assemblies and the two second lifting assemblies is within the flatness error range of the steel structure to be inspected, it means that the steel structure to be inspected has not been deformed and the welding meets the standard requirements. Otherwise, the welding does not meet the standards.

[0011] 2. In the present invention, by setting up the projection board and the laser emitter, it is possible to conveniently compare the heights of the two first lifting assemblies and the two second lifting assemblies. Specifically, when the alarm sounds an alarm, the heights of the first lifting assemblies and the second lifting assemblies can be centrally displayed on the projection board, and whether there is a height difference can be confirmed by observing the positions of the light emitted by each laser emitter on the projection board; by setting up the scale dimension line, the specific height values of the first lifting assembly and the second lifting assembly after lifting can be confirmed, which facilitates the confirmation of the deformation amount.

[0012] 3. In the present invention, the pressure switch can be protected by setting a limit assembly including a connecting column and an elastic pressure plate. Specifically, when the first lifting assembly or the second lifting assembly is lifted, the elastic pressure plate will contact the steel structure to be detected before the pressure switch. As the first lifting assembly or the second lifting assembly continues to lift, the elastic pressure plate will be compressed until the pressure switch cuts off contact with the steel structure to be detected. During this process, the elastic pressure plate will provide effective buffering to reduce the speed at which the pressure switch contacts the steel structure to be detected.

[0025] The utility model provides a steel structure welding detection device, such as Figures 1 to 3 As shown, it includes a workbench 1 and a fixture 2 for placing a steel structure 100 to be inspected, a plurality of the fixtures 2 are installed on the workbench 1 at intervals, and a gap space 3 for placing a weld is provided between the two fixtures 2 near the middle, wherein the fixture 2 and the workbench 1 are detachably connected, and different numbers of fixtures 2 can be selected according to the length of the steel structure 100 to be inspected, and also the fixture 2 that is convenient for clamping and fixing can be selected according to the different shapes of the steel structure 100 to be inspected. It also includes a detection mechanism, and the detection mechanism includes a first lifting component 4, a second lifting component 5, a pressure switch 6 and an alarm 7, the two first lifting components 4 are fixedly connected to the workbench 1, and are respectively located on both sides of the gap space 3, the two second lifting components 5 are slidably connected to the workbench 1, and are respectively located at one end of the steel structure 100 to be inspected away from the gap space 3, wherein the first lifting component 5 is slidably connected to the workbench 1, and are respectively located at one end of the steel structure 100 to be inspected away from the gap space 3, wherein the second lifting component 5 is slidably connected to the workbench 1, and are respectively located at one end of the steel structure 100 to be inspected away from the gap space 3, The two lifting assemblies 5 can slide freely on one side of the weld along the length direction of the steel structure 100 to be inspected, thereby meeting the inspection of steel structures 100 to be inspected with different lengths. A pressure switch 6 is installed on the top of the first lifting assembly 4 and the second lifting assembly 5. The pressure switch 6 moves closer to or away from the steel structure 100 to be inspected under the drive of the first lifting assembly 4 or the second lifting assembly 5. The alarm 7 is installed on the workbench 1 and is located on both sides of the fixture 2. The pressure switch 6 and the alarm 7 are connected one by one. When the pressure switch 6 contacts the steel structure to be inspected, the pressure switch 6 is closed and the alarm 7 sounds an alarm. Otherwise, the alarm 7 does not sound an alarm. The alarm 7 includes a sound alarm 7 and a light alarm 7. The combination of the two can improve the warning effect and facilitate the reminder of construction personnel.

[0026] In this embodiment, by setting up a detection mechanism including two first lifting assemblies 4, two second lifting assemblies 5, a pressure switch 6 and an alarm 7, it is possible to confirm whether the two sides of the weld of the steel structure 100 to be detected are in the same plane according to the alarm status of the alarm 7 at different positions, thereby confirming whether the overall steel structure is deformed, and then confirming whether the welding quality meets the standards. Specifically, when in use, the steel structure 100 to be detected, such as a steel beam, a steel column or a steel plate, is first effectively fixed by the clamp 2 to ensure that the weld is located in the gap space 3, and then the two second lifting assemblies 5 are separated according to the length of the steel structure 100 to be detected. Slide to the other end of the steel structure 100 to be inspected, ensure that both ends of the steel structure on each side of the weld contain a first lifting assembly 4 and a second lifting assembly 5, then control the first lifting assembly 4 and the second lifting assembly 5 to rise, and move the pressure switch 6 toward the steel structure 100 to be inspected until it contacts the steel structure 100 to be inspected, and the alarm 7 sounds an alarm. At this time, if the height difference between the two first lifting assemblies 4 and the two second lifting assemblies 5 is within the flatness error range of the steel structure 100 to be inspected, it means that the steel structure 100 to be inspected is not deformed and the welding meets the standard requirements. Otherwise, the welding does not meet the standards.

[0027] In this utility model, if Figure 1 、 Figure 2 、 Figure 3 As shown, if the steel structure 100 to be inspected is welded from straight steel plates, steel beams or steel columns, the two first lifting assemblies 4 and the two second lifting assemblies 5 can be raised synchronously during the above process. At this time, if the four alarms 7 sound an alarm at the same time, it means that the steel structure 100 to be inspected has not been deformed and the welding meets the standard requirements. Otherwise, the welding does not meet the standards.

[0028] In the present invention, preferably, Figure 1 and Figure 2 As shown, the detection mechanism also includes a projection plate 8 and a laser emitter 9. The projection plate 8 is fixedly mounted on the workbench 1 and is parallel to and spaced apart from the steel structure 100 to be detected. The laser emitter 9 corresponds one-to-one to the pressure switch 6. The laser emitter 9 is mounted on the top of the first lifting assembly 4 and the second lifting assembly 5 and is located on the side close to the projection plate 8. The emission port of the laser emitter 9 is horizontally arranged and directly opposite to the projection plate 8. The height of the laser emitter 9 is not higher than the height of the pressure switch 6.

[0029] In this embodiment, through the setting of the projection board 8 and the laser emitter 9, the lifting heights of the two first lifting assemblies 4 and the two second lifting assemblies 5 can be conveniently compared. Specifically, when the alarm 7 sounds an alarm, the lifting heights of the first lifting assemblies 4 and the second lifting assemblies 5 can be displayed on the projection board 8 by observing the height positions of the light emitted by each laser emitter 9 on the projection board 8.

[0030] In the present invention, preferably, Figure 1 and Figure 3 As shown, the projection plate 8 is provided with scale lines along the vertical direction, and the length of the scale lines along the horizontal direction is not less than the length of the steel structure 100 to be inspected.

[0031] In this embodiment, by setting the scale dimension lines, the specific height values of the first lifting component 4 and the second lifting component 5 after being lifted can be confirmed, which facilitates confirmation of the deformation amount.

[0032] In the present invention, preferably, Figure 1 、 Figure 2 and Figure 3 As shown, the tops of the first lifting assembly 4 and the second lifting assembly 5 are also provided with multiple limit assemblies 10, and the multiple limit assemblies 10 are evenly distributed on the edge of the pressure switch 6. The limit assemblies 10 include a connecting column 10a and an elastic pressure plate 10b. The connecting column 10a is fixedly installed on the tops of the first lifting assembly 4 and the second lifting assembly 5, and the elastic pressure plate 10b is fixedly installed on the top of the connecting column 10a. When the elastic pressure plate 10b is not compressed, the top of the elastic pressure plate 10b is higher than the top of the pressure switch 6. When the elastic pressure plate 10b is compressed to the limit, the top of the elastic pressure plate 10b is lower than the top of the pressure switch 6.

[0033] In this embodiment, the pressure switch 6 can be protected by setting a limit assembly 10 including a connecting column 10a and an elastic pressure plate 10b. Specifically, when the first lifting assembly 4 or the second lifting assembly 5 is lifted, the elastic pressure plate 10b will contact the steel structure to be detected 100 before the pressure switch 6. As the first lifting assembly 4 or the second lifting assembly 5 continues to lift, the elastic pressure plate 10b will be compressed until the contact between the pressure switch 6 and the steel structure to be detected 100 is cut off. During this process, the elastic pressure plate 10b will provide effective buffering to reduce the speed at which the pressure switch 6 contacts the steel structure to be detected 100.

[0034] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
