Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering detection, and more specifically, it relates to a steel bar sampling and cutting device for engineering detection. Background Technology

[0002] Rebar sampling for engineering testing refers to the process of extracting steel bar samples from the concrete structure of the construction project in order to conduct quality tests on these samples such as mechanical properties, nominal diameter, and corrosion characteristics. This process is a key step in construction and engineering testing because it can ensure that the steel bar materials used meet the design requirements and national standards, thereby ensuring the safety and durability of the building structure.

[0003] The steel bar sampling and cutting device for engineering testing is a device specially used to cut steel bar samples from concrete components to facilitate quality testing of the mechanical properties, nominal diameter, corrosion characteristics, etc. of the steel bars. This device has important application value in the fields of construction and engineering testing. It can ensure that the steel bar samples obtained meet the relevant standards and regulations, thereby providing accurate evaluation data for the quality of the project. The steel bar sampling and cutting device for engineering testing is mainly used for sampling steel bars of components in civil engineering such as housing construction, bridges, and roads. These samples are used to evaluate the performance of the structure and determine the quality of the project.

[0004] During the steel bar cutting process, the high-speed friction between the cutting machine and the steel bar will generate a large amount of heat, which is enough to melt the metal locally. Under the action of the high-speed rotating cutting blade, the molten metal is thrown out and quickly cooled, forming fine metal dust and fragments. Due to the good thermal conductivity of metal, the heat generated by friction spreads rapidly, increasing the amount of metal dust and fragments. If the operator is exposed to high concentrations of metal dust for a long time, it will cause serious damage to the human respiratory system. In addition, metal dust and fragments splashing on the skin or eyes will cause mechanical irritation or injury. Moreover, these metal dust and fragments enter the soil and water sources, which will affect the survival of plants and animals and destroy the ecological balance.

[0005] Therefore, in order to solve the above technical problems, the present invention proposes a steel bar sampling and cutting device for engineering inspection. SUMMARY OF THE INVENTION

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In the present invention, through the dust removal component provided on the support arm, the metal dust, iron filings, and sparks generated by the obstruction of the protective cover will always be inside the protective cover. At the same time, the exhaust fan is started. When the exhaust fan is started, suction will be generated. At this time, the suction will come to the conveying pipe through the filter holes on the storage box. At this time, the generated metal dust and iron filings will come to the storage box from the conveying pipe due to the exhaust fan. At this time, the filter holes in the storage box will block the metal dust and iron filings from entering the exhaust fan. At the same time, the filter screen will intercept the metal dust and iron filings again to prevent the metal dust and iron filings from entering the exhaust fan and damaging the exhaust fan. Thus, the problem in the background technology is solved that the operator is exposed to high-concentration metal dust for a long time, which will cause serious damage to the human respiratory system, and the metal dust and debris splashing on the skin or eyes will cause mechanical irritation or injury, and these metal dust and debris entering the soil and water sources will affect the survival of plants and animals and damage the ecological balance.

[0025] 2. In the present invention, through the cleaning component provided at the telescopic end of the electric telescopic rod, when the electric telescopic rod drives the cutting head to move downward towards the steel bar, the connecting frame at this time will also move downward together with the telescopic end of the electric telescopic rod. When the connecting frame moves downward, the scraper will also move downward together with the connecting frame. When the cutting head finishes cutting the steel bar king and moves upward through the electric telescopic rod, the scraper will move upward together with the connecting frame. When the scraper moves upward, it will clean the metal dust and iron filings adhered to the inner wall of the conveying pipe, so as to achieve cleaning the iron filings and metal dust inside the conveying pipe through the scraper, which can effectively extend the service life of the conveying pipe.

[0026] 3. In the present invention, through the taking and placing component provided on the storage box, hold the two anti-slip plates simultaneously and move the anti-slip plates closer to each other. When the anti-slip plates move, they will drive the limiting plate to move. When the limiting plate moves towards the sliding hole, it will compress the spring until the limiting plate completely disengages from the limiting hole. At this time, pull the handle to pull out the storage box from the conveying pipe, and then clean the storage box. After cleaning, hold the two anti-slip plates simultaneously and move the anti-slip plates closer to each other. When the anti-slip plates move, they will drive the limiting plate to move. When the limiting plate moves towards the sliding hole, it will compress the spring until the limiting plate completely enters the storage box. Then hold the handle, align the storage box with the slide rail inside the conveying pipe and insert it. When the storage box is completely inserted into the conveying pipe, release the anti-slip plates. At this time, the spring will no longer receive the extrusion force, and the spring will push the limiting plate into the limiting groove through its resilience and prevent the limiting plate from disengaging from the limiting hole, so as to achieve the rapid installation and disassembly of the storage box, which can effectively improve the efficiency of taking and placing the storage box.

[0027] 4. In the present invention, through the sound insulation board and sound absorption cotton arranged in the protective cover, the noise generated when the cutting head cuts the steel bar will be blocked by the sound insulation board and sound absorption cotton, so as to reduce the noise, effectively solve the problems that the noise and vibration generated during the cutting process will damage the hearing of the operator, and will also cause noise pollution to the surrounding environment and affect people's quality of life.

[0036] As Figures 1-6As shown in the figure, the present invention provides a steel bar sampling and cutting device for engineering detection, including a support plate 1 and an electric telescopic rod 10. Support arms 3 are mirror-mounted on the support plate 1, which are used to achieve the supporting function. It also includes:

[0037] A dust removal component 12 arranged on the support arm 3, which is used to solve the problem that long-term exposure of operators to high-concentration metal dust will cause serious damage to the human respiratory system, and metal dust and debris splashing onto the skin or eyes will cause mechanical irritation or injury. Moreover, when these metal dust and debris enter the soil and water sources, they will affect the survival of plants and animals and damage the ecological balance. The dust removal component 12 includes a protective cover 1201. A protective cover 1201 is installed between the support arm 3 and the support plate 1 and at the upper end, which is used to prevent metal dust and iron filings from splashing into the environment and onto the operator. The protective cover 1201 is transparent, which is used to facilitate observing whether the steel bar cutting part is aligned with the cutting head 11 through the protective cover 1201. Sound insulation boards 1202 are installed on both sides of the protective cover 1201, and a sound-absorbing cotton 1203 is installed on the side of each sound insulation board 1202 away from the protective cover 1201, which is used to reduce the noise generated during cutting. A conveying pipe 1204 is installed between the two support arms 3 and the support plate 1 and at the lower end, which is used to convey metal dust and iron filings. A receiving box 1205 is slidably installed at the end of the conveying pipe 1204 away from the support arm 3, which is used to centrally collect metal dust and iron filings. A plurality of filter holes 1206 are opened at the bottom of the receiving box 1205, which is used to achieve ventilation. One end of the conveying pipe 1204 close to the receiving box 1205 is connected to an exhaust fan 1207. The exhaust fan 1207 and the filter holes 1206 on the receiving box 1205 are mutually communicated, which is used to enable the suction force of the exhaust fan 1207 to reach the inside of the conveying pipe 1204 through the filter holes 1206. A filter net 1209 is installed at the end of the exhaust fan 1207 connected to the conveying pipe 1204, which is used to prevent metal dust and iron filings from entering the exhaust fan 1207. A plurality of heat dissipation openings 1208 are opened at the end of the exhaust fan 1207 away from the filter net 1209, which is used to dissipate heat from the exhaust fan 1207.

[0038] The telescopic end of the electric telescopic rod 10 is provided with a cleaning assembly 13, which is used to clean the iron filings and metal dust inside the conveying pipe 1204 through a scraper 1302, so as to extend the service life of the conveying pipe 1204. The cleaning assembly 13 includes a connecting frame 1301, and the telescopic end of the electric telescopic rod 10 is installed with the connecting frame 1301, which is used to achieve the function of connection and transmission. The end of the connecting frame 1301 away from the electric telescopic rod 10 is connected with a scraper 1302, which is used to clean the inner wall of the conveying pipe 1204. The scraper 1302 is located inside the delivery pipe 1204 and fits against the inner wall of the delivery pipe 1204. The scraper 1302 and the connecting frame 1301 can slide vertically inside the delivery pipe 1204. A baffle 1303 is installed at one end of the delivery pipe 1204 close to the support arm 3. The size of the baffle 1303 is larger than the scraper 1302 and the baffle 1303 blocks the scraper 1302 inside the delivery pipe 1204, which is used to prevent the scraper 1302 from escaping from the delivery pipe 1204.

[0039] The storage box 1205 is provided with a pick-and-place assembly 14, which is used to quickly install and disassemble the storage box 1205, so as to improve the efficiency of taking and placing the storage box 1205. The pick-and-place assembly 14 includes a sliding hole 1401. The storage box 1205 is mirror-imaged with a sliding hole 1401. Each sliding hole 1401 is slidably connected to a limiting plate 1402, which is used to facilitate fixing and unlocking. Each limiting plate 1402 penetrates the storage box 1205 and can slide on the storage box 1205, and an anti-skid plate 1403 is installed at one end of each limiting plate 1402 in the sliding hole 1401, which is used to facilitate transmission. Each anti-skid plate 1403 can slide in the sliding hole 1401, and each anti-skid plate 1403 extends out of the sliding hole 1401. Each limiting plate 1402 is connected to the slide hole 1401 by a spring 1404, which is used to facilitate the automatic pushing of the limiting plate 1402 into the limiting hole 1406 by the resilience of the spring 1404. Symmetrical slide rails 1405 are provided on both sides of the conveying tube 1204 to achieve limited sliding. A limiting hole 1406 is provided in each slide rail 1405. The two slide holes 1401 are mirror-imaged. Each limiting plate 1402 can slide in the limiting holes 1406 close to each other, which is used to insert the limiting plate 1402 into the limiting hole 1406, so as to fix the storage box 1205 in the conveying tube 1204. A handle 1407 is installed on the side of the storage box 1205 outside the conveying tube 1204 to achieve the effect of anti-slip.

[0040] A holding rod 2 is installed on the support plate 1, which is used to achieve the function of maintaining stability. A clamping opening 4 is formed on each support arm 3, and a clamping plate A5 is installed at the lower end of each clamping opening 4. A screw rod 8 is slidably installed at the upper end of each support arm 3 corresponding to the clamping opening 4, which is used to achieve the vertical movement of the adjustment clamping plate B7. Each screw rod 8 extends to the clamping opening 4 and can slide on the support arm 3, and one end of each screw rod 8 in the clamping opening 4 is connected with a clamping plate B7, which is used to achieve the stability of the steel bar to be cut by the cooperation of the clamping plate B7 and the clamping plate A5. A non-slip pad 6 is installed on one side of each clamping plate B7 corresponding to each clamping plate A5, which is used to avoid the sliding of the steel bar when cutting the steel bar. A support rod 9 is installed on the support plate 1, and the support rod 9 extends to the protective cover 1201 and corresponds to it. An electric telescopic rod 10 is installed on the support rod 9, which is used to achieve the vertical movement of the control cutting head 11. The telescopic end of the electric telescopic rod 10 extends into the protective cover 1201 and can slide vertically on the protective cover 1201. The telescopic end of the electric telescopic rod 10 inside the protective cover 1201 is installed with a cutting head 11, which is used to facilitate the cutting of the steel bar.

[0041] Working principle: When it is necessary to sample and cut steel bars, first insert the steel bar into the two clamping ports 4, and then observe through the transparent protective cover 1201 until the position of the steel bar to be cut corresponds to the cutting head 11. Then rotate the screw rod 8. At this time, the screw rod 8 will drive the clamping plate B7 and the anti-slip pad 6 on the clamping plate B7 to move towards the clamping plate A5 until the anti-slip pad 6 on the clamping plate B7 fits the steel bar. At this time, the steel bar will be firmly clamped. Then start the cutting head 11, and then start the electric telescopic rod 10. At this time, the electric telescopic rod 10 will drive the cutting head 11 to move towards the steel bar until the cutting head 11 touches the steel bar and cuts the steel bar. At the same time, when the cutting head 11 cuts the steel bar, metal dust, iron filings and sparks will be generated. At this time, due to the blockage of the protective cover 1201, the generated metal dust, iron filings and sparks will always be inside the protective cover 1201. At the same time, start the exhaust fan 1207. When the exhaust fan 1207 starts, suction will be generated. At this time, the suction will come to the conveying pipe 1204 through the filter holes 1206 on the storage box 1205. At this time, the generated metal dust and iron filings will come to the storage box 1205 from the conveying pipe 1204 due to the exhaust fan 1207. At this time, the filter holes 1206 in the storage box 1205 will block the metal dust and iron filings from entering the exhaust fan 1207, so as to collect the metal dust and iron filings in the storage box 1205. At the same time, the filter net 1209 will intercept the metal dust and iron filings for the second time to avoid the metal dust and iron filings entering the exhaust fan 1207 and damaging the exhaust fan 1207, so as to extend the service life of the exhaust fan 1207. At the same time, the noise generated when the cutting head 11 cuts the steel bar will be blocked by the sound-absorbing board and the sound-absorbing cotton 1203, so as to reduce the noise;

[0042] When the electric telescopic rod 10 drives the cutting head 11 to move downward towards the steel bar, at this time the connecting frame 1301 will also move downward together with the telescopic end of the electric telescopic rod 10. When the connecting frame 1301 moves downward, the scraper 1302 will also move downward together with the connecting frame 1301. When the cutting head 11 finishes cutting the steel bar and moves upward through the electric telescopic rod 10, the scraper 1302 will move upward together with the connecting frame 1301. When the scraper 1302 moves upward, it will clean the metal dust and iron filings adhered to the inner wall of the conveying pipe 1204, so as to keep the conveying pipe 1204 clean;

[0043] When a certain amount of metal dust and iron filings accumulate in the storage box 1205, at this time, hold two anti-slip plates 1403 simultaneously and move the anti-slip plates 1403 closer to each other. When the anti-slip plates 1403 move, they will drive the limit plate 1402 to move. When the limit plate 1402 moves towards the sliding hole 1401, it will compress the spring 1404. Until the limit plate 1402 completely disengages from the limit hole 1406, at this time, hold the handle 1407 and pull out the storage box 1205 from the conveying pipe 1204, and then clean the storage box 1205. After cleaning, hold two anti-slip plates 1403 simultaneously and move the anti-slip plates 1403 closer to each other. When the anti-slip plates 1403 move, they will drive the limit plate 1402 to move. When the limit plate 1402 moves towards the sliding hole 1401, it will compress the spring 1404 until the limit plate 1402 completely enters the storage box 1205. Then hold the handle 1407, align the storage box 1205 with the slide rail 1405 in the conveying pipe 1204 and insert it. When the storage box 1205 is completely inserted into the conveying pipe 1204, release the anti-slip plates 1403. At this time, the spring 1404 will no longer be under extrusion pressure, and the spring 1404 will push the limit plate 1402 into the limit groove through its resilience and prevent the limit plate 1402 from disengaging from the limit hole 1406, so as to realize the rapid installation and disassembly of the storage box 1205 and facilitate improving the efficiency of taking and placing the storage box 1205.
