A building steel structure weld detection device

Abstract

This utility model discloses a steel structure weld inspection device, including a mounting plate slidably mounted on the outer surface of the inspection instrument. A sliding mechanism is provided inside the lubricant storage tank, which squeezes out the lubricant from the storage tank, facilitating the application of lubricant to the outer surface of the steel structure weld. During use, the ultrasonic testing probe moves up and down, driving a piston that moves within the lubricant storage tank. A one-way valve, when the piston rises, draws in the lubricant; the downward pressure of the piston, combined with the one-way valve, pumps the lubricant out, allowing it to enter the distribution nozzle and be evenly sprayed onto the outer surface of the steel structure. Then, a brush moves, spreading the lubricant evenly across the surface. This allows for convenient use and application without the need to carry lubricant or a brush.

Description

Technical Field

[0001] This utility model relates to the field of building steel structure inspection technology, specifically a building steel structure weld inspection device. Background Technology

[0002] When welding and installing steel structures, it is necessary to inspect the welds to ensure the stability and strength of the welds. A weld inspection instrument is a portable ultrasonic defect detector that can quickly, conveniently, non-destructively, and accurately inspect the inside of steel structure welds, and locate, evaluate, and diagnose defects such as cracks, inclusions, porosity, incomplete penetration, and lack of fusion within the steel structure.

[0003] The existing patent document with publication number CN209416984U provides a device for inspecting welds in building steel structures. A square box is fixedly installed on the side wall of the weld inspector. A first groove is opened on the square box, and a spring is fixedly installed in the first groove. The other end of the spring is fixedly installed on the neck of a pin. A square block is fixedly connected to the end of the pin. A clip is fixedly installed on the detector. A first clamping arm and a support plate are fixedly installed on the upper surface of the weld inspector. A second clamping arm is slidably connected in a groove opened on the support plate. A lead screw is threadedly connected to a first threaded hole opened on the first clamping arm and a second threaded hole opened on the second clamping arm.

[0004] Regarding the aforementioned related technologies, the inventors have discovered that the technology has at least the following problems: the detector in the aforementioned patent documents cannot easily apply lubricant to the outer surface of the weld when in use, making it very inconvenient to bring a separate brush and lubricant for brushing. Utility Model Content

[0005] The purpose of this utility model is to provide a device for inspecting welds in building steel structures, so as to solve the problem mentioned in the background art that it is very inconvenient to carry a lubricant and a brush for application.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure weld inspection device, comprising a mounting plate, the mounting plate being slidably mounted on the outer surface of an inspection instrument, and the inspection instrument engaging with the mounting plate; a rolling ball being fixedly mounted on the mounting plate near the outer surface of the inspection instrument, and the rolling ball being in contact with the outer surface of the inspection instrument; a lubricant storage box being fixedly mounted on the outer surface of one end of the mounting plate, and the outer surface of the lubricant storage box being in contact with the outer surface of the mounting plate; an ultrasonic testing probe being mounted through the outer surface of the mounting plate, and the output end of the ultrasonic testing probe being connected to the inspection instrument; a sliding mechanism being provided inside the lubricant storage box, through which lubricant in the lubricant storage box is squeezed out, facilitating the application of lubricant to the outer surface of the steel structure weld.

[0007] Preferably, the sliding mechanism includes: a piston, which is slidably mounted on the outer surface of the lubricant storage tank near the ultrasonic detection probe, and the lubricant storage tank and the piston are connected by sliding friction; a one-way valve is fixedly installed inside the lubricant storage tank, and the one-way valve is located at the lowest point of the lubricant storage tank; another one-way valve is fixedly installed on the outer surface of the mounting plate, and the input end of the one-way valve penetrates through the outer surface of the lubricant storage tank; a brush is snapped onto the outer surface of the mounting plate, and one end of the brush is in contact with the outer surface of the steel structure; a uniformly distributed nozzle is fixedly installed on the outer surface of the mounting plate, and the uniformly distributed nozzle has nozzles evenly arranged on its outer surface, and the uniformly distributed nozzle is connected to the one-way valve on the outer surface of the mounting plate.

[0008] Using the above technical solution, the downward pressure of the ultrasonic detection probe drives the piston to slide inside the lubricant storage tank. The upward movement of the piston and the one-way valve allow the lubricant to be drawn into the other side of the lubricant storage tank. The downward pressure of the piston and the one-way valve allow the lubricant to be directly pumped into the interior of the equalizing nozzle and evenly discharged. As the mounting plate moves, it drives the brush to brush the sprayed lubricant, so that the lubricant is evenly coated on the outer surface of the steel structure weld. This eliminates the need to carry a brush and lubricant, making it convenient to use.

[0009] Preferably, a scraper is fixedly installed at the end of the mounting plate away from the ultrasonic testing probe, and the outer surface of the scraper is in contact with the outer surface of the steel structure.

[0010] By adopting the above technical solution, the movement of the mounting plate can drive the scraper to move, thereby cleaning the dust and impurities on the outer surface of the steel structure and reducing the impact of dust and impurities on the ultrasonic detection probe.

[0011] Preferably, the lubricant storage tank has an oil filling port on the outer surface of the end away from the mounting plate, the interior of the lubricant storage tank is designed to be inclined, and observation windows are fixedly installed on both outer surfaces of the lubricant storage tank, and the observation windows are designed to be long and transparent.

[0012] By adopting the above technical solution, lubricant can be injected into the lubricant storage tank through the oil inlet, which facilitates the storage of lubricant. The remaining lubricant level can be observed through the observation window. At the same time, the inclined design of the lubricant storage tank can move the lubricant toward the one-way valve, making it easier for the lubricant to be pumped out.

[0013] Preferably, an elastic sliding mechanism is provided between the mounting plate and the ultrasonic testing probe. The elastic sliding mechanism allows the ultrasonic testing probe to automatically retract into the mounting plate when not in use, reducing the chance of damage to the ultrasonic testing probe, and at the same time, it can pump out the lubricant in the lubricant storage tank.

[0014] By adopting the above technical solution, one end of the ultrasonic testing probe can be retracted into the mounting plate, reducing the chance of damage when the ultrasonic testing probe is not in use, protecting the ultrasonic testing probe, and extending the service life of the ultrasonic testing probe.

[0015] Preferably, the elastic sliding mechanism includes: a guide bolt, the guide bolt being threadedly mounted on the outer surface of the mounting plate, a fixing plate being mounted through the outer surface of the guide bolt, and a spring being provided between the fixing plate and the mounting plate, the spring passing through the guide bolt; a set screw being threadedly mounted on the outer surface of the fixing plate, the set screw being in contact with the outer surface of the ultrasonic testing probe; one end of the outer surface of the fixing plate being in contact with the outer surface of the lubricant storage tank; and one end of the outer surface of the fixing plate being connected to the piston.

[0016] Using the above technical solution, when inspecting the welds of steel structures, the ultrasonic testing probe can be pressed down so that the testing surface of the ultrasonic testing probe is in contact with the outer surface of the weld for inspection. As the ultrasonic testing probe is pressed down, the fixing plate will follow and push the piston. When not in use, the spring will push the fixing plate back, causing the fixing plate to retract the ultrasonic testing probe into the mounting plate, protecting the ultrasonic testing probe and extending its service life. At the same time, it can also move the piston to pump out the lubricant in the lubricant storage tank.

[0017] Preferably, the end of the ultrasonic detection probe away from the rolling ball is fixedly mounted with a gripping and fixing top plate, and a hand handle is fixedly mounted on the side surface of the gripping and fixing top plate, and an arc-shaped plane is provided on the outer surface of one end of the hand handle.

[0018] The above technical solution allows for easy gripping and squeezing of the handle, facilitating the handling of the detection device. It also allows for easy pressing down of the ultrasonic detection probe, and the gripping and fixing top plate can be removed when replacing the ultrasonic detection probe.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This steel structure weld inspection device for buildings:

[0020] 1. During use, the ultrasonic testing probe moves up and down, which drives the piston to move. The piston moves up and down inside the lubricant storage tank. With the help of the one-way valve, the lubricant is drawn in when the piston rises. With the one-way valve and the piston pressing down, the lubricant is pumped out, allowing the lubricant to enter the evenly distributed nozzle and be evenly sprayed onto the outer surface of the steel structure. Then, with the movement of the brush, the lubricant is evenly applied to the outer surface of the steel structure. This allows the device to be used and applied conveniently without the need to carry lubricant and a brush.

[0021] 2. The lubricant storage tank can store lubricant, and the observation windows on both sides of the lubricant storage tank can show how much lubricant is left in the tank. The tilting mechanism of the lubricant storage tank allows all the lubricant in the tank to move towards the one-way valve when the lubricant is low, facilitating the storage and pumping out of the lubricant.

[0022] 3. The rolling ball bearings allow the mounting plate to move along with the ball bearings during testing. This movement of the mounting plate, in conjunction with the scraper, removes impurities and dust from the outer surface of the steel structure, reducing the impact of dust on the ultrasonic testing probe and improving the accuracy of the ultrasonic testing probe.

[0023] 4. During testing, the ultrasonic testing probe can be pressed down to move the fixing plate, which moves along the direction of the guide bolts, allowing the ultrasonic testing probe to come into contact with the outer surface of the weld. With the help of lubricant, the accuracy of the test is improved. At the same time, when not testing, the spring will push the fixing plate back, causing the ultrasonic testing probe to retract into the mounting plate, protecting the ultrasonic testing probe and extending its service life.

[0024] 5. When inspecting welds, the mounting plate and ultrasonic testing probe can be gripped and held by the handle, reducing the chance of the device slipping and falling, and reducing the chance of damage to the ultrasonic testing probe and lubricant storage box if they fall. At the same time, it is convenient to move the mounting plate with the ultrasonic testing probe to inspect the weld. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-7 This utility model provides a technical solution: a device for detecting weld seams in building steel structures.

[0035] Example 1

[0036] This embodiment discloses: a mounting plate 1, which is slidably mounted on the outer surface of a testing instrument 17, and the testing instrument 17 is engaged with the mounting plate 1. A rolling ball 2 is fixedly mounted on the mounting plate 1 near the outer surface of the testing instrument 17, and the rolling ball 2 is in contact with the outer surface of the testing instrument 17. A lubricant storage box 4 is fixedly mounted on one end of the outer surface of the mounting plate 1, and the outer surface of the lubricant storage box 4 is in contact with the outer surface of the mounting plate 1. An ultrasonic testing probe 3 is installed through the outer surface of the mounting plate 1, and the output end of the ultrasonic testing probe 3 is connected to the testing instrument 17. A sliding mechanism is provided inside the lubricant storage box 4, which squeezes out the lubricant in the lubricant storage box 4 to facilitate the application of lubricant to the outer surface of the steel structure weld. The sliding mechanism includes a piston 14, which is slidably mounted on the lubricant storage box. 4. On the outer surface of the side close to the ultrasonic detection probe 3, the lubricant storage tank 4 and the piston 14 are connected by sliding friction. A one-way valve 15 is fixedly installed inside the lubricant storage tank 4, and the one-way valve 15 is located at the lowest point of the lubricant storage tank 4. Another one-way valve 15 is fixedly installed on the outer surface of the mounting plate 1, and the input end of the one-way valve 15 penetrates through the outer surface of the lubricant storage tank 4. A brush 6 is snapped onto the outer surface of the mounting plate 1, and one end of the brush 6 is in contact with the outer surface of the steel structure. A uniformly distributed nozzle 16 is fixedly installed on the outer surface of the mounting plate 1, and the nozzles are evenly arranged on the outer surface of the uniformly distributed nozzle 16. The uniformly distributed nozzle 16 is connected to the one-way valve 15 on the outer surface of the mounting plate 1. A scraper 7 is fixedly installed on the end of the mounting plate 1 away from the ultrasonic detection probe 3, and the outer surface of the scraper 7 is in contact with the outer surface of the steel structure.

[0037] When using the device, the mounting plate 1 needs to be removed from the side surface of the testing instrument 17 and placed on the outer surface of the steel structure weld. Then, by rolling the ball bearing 2, the mounting plate 1 can slide freely on the outer surface of the steel structure. The movement of the scraper 7 and the mounting plate 1 can remove dust and other impurities from the outer surface of the steel structure, facilitating the movement of the ultrasonic testing probe 3 and reducing the influence of impurities on the ultrasonic testing probe 3. As the piston 14 slides up and down inside the lubricant storage tank 4, the lubricant can be pumped into the evenly distributed nozzle 16 in conjunction with the one-way valve 15, and then evenly discharged from the evenly distributed nozzle 16 to the outer surface of the steel structure. The brush 6 evenly spreads the lubricant, allowing it to make uniform contact with the ultrasonic testing probe 3, improving the adhesion between the ultrasonic testing probe 3 and the outer surface of the weld, and improving the detection accuracy of the ultrasonic testing probe 3. At the same time, there is no need to carry lubricant and brush during use, improving the ease of use of the device.

[0038] Example 2

[0039] This embodiment, based on Embodiment 1, discloses the following: An oil filling port is provided on the outer surface of the lubricant storage tank 4 at the end furthest from the mounting plate 1. The interior of the lubricant storage tank 4 is designed to be inclined, and observation windows 5 are fixedly installed on both outer surfaces of the lubricant storage tank 4. These observation windows 5 are elongated and transparent. An elastic sliding mechanism is provided between the mounting plate 1 and the ultrasonic testing probe 3. This mechanism allows the ultrasonic testing probe 3 to automatically retract into the mounting plate 1 when not in use, reducing the probability of damage to the ultrasonic testing probe 3. Simultaneously, it allows the lubricant storage tank 4 to... The lubricant is pumped out from the inside. The elastic sliding mechanism includes: a guide bolt 8, which is threaded onto the outer surface of the mounting plate 1. A fixing plate 10 is installed through the outer surface of the guide bolt 8, and a spring 9 is provided between the fixing plate 10 and the mounting plate 1, and the spring 9 passes through the guide bolt 8. A set screw 11 is threaded onto the outer surface of the fixing plate 10, and the set screw 11 is in contact with the outer surface of the ultrasonic detection probe 3. One end of the outer surface of the fixing plate 10 is in contact with the outer surface of the lubricant storage tank 4, and one end of the outer surface of the fixing plate 10 is connected to the piston 14.

[0040] By adding the above structure, lubricant can be injected into the lubricant storage tank 4 through the injection port for easy carrying. The remaining capacity of the lubricant can be observed through the observation windows 5 on both sides of the lubricant storage tank 4. The inclined design of the lubricant storage tank 4 allows all the lubricant to flow to the one-way valve 15 for easy pumping out of the lubricant. When it is necessary to inspect the weld, the ultrasonic testing probe 3 can be pressed down first, causing the fixing plate 10 to slide along the direction of the guide bolt 8. Then, the spring 9 will push the fixing plate 10 back, causing the fixing plate 10 to drive the piston 14 to slide up and down to pump out the lubricant. This allows the ultrasonic probe 3 to descend and fit against the outer surface of the steel structure. When not in use, the spring 9 pushes the fixing plate 10 back, causing the ultrasonic probe 3 to move and retract into the mounting plate 1 to protect it. This protects the ultrasonic probe 3 when the device is not in use. When the ultrasonic probe 3 needs to be replaced, the set screw 11 can be loosened to remove it from the fixing plate 10, making replacement convenient and extending its service life while reducing the probability of damage.

[0041] Example 3

[0042] This embodiment discloses, based on Embodiments 1 and 2: a gripping and fixing top plate 12 is fixedly installed at the end of the ultrasonic detection probe 3 away from the rolling ball 2, and a hand grip 13 is fixedly installed on the side surface of the gripping and fixing top plate 12, and an arc-shaped plane is provided on the outer surface of one end of the hand grip 13.

[0043] By adding the above structure, the grip handle 13 can be used to grasp and hold the top plate 12, allowing the hand to hold the entire detection device and reducing the chance of slippage during detection. The ultrasonic detection probe 3 can be easily moved for detection when pressed down by the rolling ball 2. When replacing the ultrasonic detection probe 3, the grip control top plate 12 can be removed from the ultrasonic detection probe 3, which facilitates detection movement while reducing the chance of slippage and drop of the grip device.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
