Description

Technical Field

[0001] This invention relates to the field of steel testing technology, and in particular to a steel strength testing device. Background Technology

[0002] Steel is a material with a certain shape, size, and properties that is made from steel ingots, billets, or steel through pressure processing. Most steel processing is done through pressure processing, which causes plastic deformation of the steel (billets, ingots, etc.).

[0003] After steel is processed, it undergoes strength testing using testing equipment. Existing testing equipment involves confining the steel within the testing device and then using a testing head to perform the test. To ensure stability during testing, a limiting component is used to restrict the steel. However, the existing limiting component only uses two corresponding second limiting plates to restrict the steel. When dealing with larger steel pieces with higher strength, the limiting effect of the second limiting plates becomes limited, compromising the stability of the steel during testing. Furthermore, due to the lack of protective components on the equipment, if the steel breaks during strength testing, steel fragments and pieces will scatter around the testing device, jeopardizing the safety of nearby operators. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing testing equipment cannot protect operators when testing steel, and to propose a steel strength testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A steel strength testing device includes a processing table. A connecting lug and a guide rod are fixedly installed on the processing table. The guide rod is movably sleeved with a symmetrically arranged and integrally connected guide block and a connecting rod. A first limiting block and a second limiting block are fixedly installed on the connecting rod and integrally connected. The first limiting block has a placement hole for placing steel. The first limiting block and the second limiting block are respectively equipped with a limiting component and a reinforcing component for limiting and reinforcing the steel. A protective component is installed on the connecting lug.

[0006] Preferably, the limiting component includes a lead screw rotatably mounted on the first limiting block, a matching nut movably sleeved on the lead screw, and a first limiting plate integrally connected to the nut for limiting the steel.

[0007] Preferably, the lead screw is vertically arranged, and a handle extending beyond the first limiting block is fixedly installed on the lead screw. A limiting bolt that is detachably connected to the first limiting block is fixedly installed on the handle, and the first limiting plate is an arc-shaped structure adapted to steel.

[0008] Preferably, the reinforcement component includes a first clamping plate and a second clamping plate movably sleeved within the fixed plate. A second limiting plate corresponding to the steel is integrally connected to both the first clamping plate and the second clamping plate. An anti-slip layer in contact with the steel is embedded in the second limiting plate.

[0009] Preferably, a fixing bolt is detachably installed between the first clamping plate and the second clamping plate, and a limiting frame is detachably extended into the first clamping plate and the second clamping plate on the second limiting block, wherein the second limiting plate is an arc-shaped structure adapted to the steel.

[0010] Preferably, the protective component includes a bracket fixedly installed on the connecting ear, and a telescopic rod is fixedly installed on the bracket. The output end of the telescopic rod is integrally connected to a sealing cover for sealing the steel, and a detection head for detecting the steel is fixedly installed inside the sealing cover.

[0011] Preferably, the sealing cover has a transparent observation window on one side, and the sealing cover has a U-shaped structure with an open bottom. Both the bracket and the sealing cover have limiting holes for limiting the steel.

[0012] Preferably, the processing table is a U-shaped structure with an opening on one side, and the connecting ears are horizontally arranged on both sides of the processing table.

[0013] Preferably, the guide rod is horizontally arranged, and a fixing block for limiting the guide block is detachably installed on the guide rod.

[0014] Preferably, the processing table has a guide hole for guiding the connecting rod, and the first limiting block, the second limiting block and the connecting rod extend to the upper position outside the processing table.

[0015] Compared with the prior art, the present invention has the following advantages: This invention uses the traction of a handle to cause a nut to move a first limiting plate downwards, initially limiting the steel. By setting the first limiting plate to an arc-shaped structure adapted to the steel, the contact area between the first limiting plate and the steel is increased, enabling the first limiting plate to limit steel of different specifications and increasing the adaptability of the testing equipment. The steel is limited from both sides by a first clamping plate and a second clamping plate, and then the first clamping plate and the second clamping plate are fixed to a second limiting block by a limiting frame, so that the steel can be limited within the placement hole by the clamping plates and the second limiting plate, thereby ensuring the stability of the steel after placement and effectively improving the efficiency of steel testing.

[0016] 2. This invention allows the sealing cover to seal the steel by lowering the output end of the telescopic rod. This protects the operator in the event of steel breakage during testing, preventing injury from debris or steel fragments caused by steel breakage due to the lack of protective measures. This ensures the operator's safety during operation.

[0017] In summary, this invention uses the traction of the handle to cause the nut to move the first limiting plate downwards, initially limiting the steel. By setting the first limiting plate to an arc-shaped structure adapted to the steel, the contact area between the first limiting plate and the steel is increased, allowing the first limiting plate to limit steel of different specifications, thus increasing the adaptability of the testing equipment. The first and second clamping plates limit the steel from both sides, and the limiting frame fixes the first and second clamping plates to the second limiting block, ensuring that the steel is contained within the placement hole. This guarantees the stability of the steel after placement and effectively improves the efficiency of steel testing. The downward movement of the telescopic rod output end allows the sealing cover to seal the steel during the downward movement, protecting the operator in case the steel breaks during testing. This avoids injury to the operator from debris or steel fragments caused by steel breakage without protective measures, ensuring the operator's safety during operation. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figures 1-4 A steel strength testing device, including a processing table 1, as shown in the attached instruction manual. Figure 1 As shown, a connecting ear 2 and a guide rod 3 are fixedly installed on the processing table 1. The processing table 1 is a U-shaped structure with an opening on one side, and the connecting ear 2 is horizontally set on both sides of the processing table 1. The guide rod 3 is movably fitted with a guide block 4 and a connecting rod 5 that are symmetrically arranged and integrally connected. The guide rod 3 is horizontally set, and a fixing block 6 for limiting the guide block 4 is detachably installed on the guide rod 3. It should be noted that by installing the fixing block 6 on the guide rod 3, the guide block 4 can be limited. The connecting rod 5 is fixedly installed with an integrally connected first limiting block 7 and second limiting block 8. The processing table 1 is provided with a guide hole for guiding the connecting rod 5. The guide hole guides and limits the connecting rod 5, so that the connecting rod 5 can smoothly pull the first limiting block 7 and the guide block 4 when moving. The first limiting block 7, the second limiting block 8 and the connecting rod 5 extend to the upper position outside the processing table 1. The first limiting block 7 has a placement hole 9 for placing steel, as shown in the instruction manual. Figure 3 As shown, the placement hole 9 and the inner wall of the first limiting plate 12 are fitted with soft pads that come into contact with the steel, so that the steel will not be excessively worn due to excessive pressure when it is tested in the placement hole 9, thereby ensuring the normal testing of the steel. The first limiting block 7 and the second limiting block 8 are respectively equipped with limiting components and reinforcing components for limiting and reinforcing the steel, and the connecting ear 2 is equipped with protective components for protection. Further explanation; The limiting assembly includes a lead screw 10 rotatably mounted on the first limiting block 7, a matching nut 11 movably sleeved on the lead screw 10, and a first limiting plate 12 integrally connected to the nut 11 for limiting the steel. By pulling the handle, the first limiting plate 12 can limit the steel in the placement hole 9 after it moves. And by moving the nut 11 up and down, the first limiting plate 12 can limit steel of different specifications, thereby improving the adaptability of the testing equipment. The lead screw 10 is vertically set, and a handle extending beyond the first limiting block 7 is fixedly installed on the lead screw 10. A limiting bolt that is detachably connected to the first limiting block 7 is fixedly installed on the handle. The first limiting plate 12 is an arc-shaped structure adapted to the steel. By setting the first limiting plate 12 to an arc-shaped structure adapted to the steel, the contact area between the first limiting plate 12 and the steel is increased, so that the steel can be initially limited by the first limiting plate 12 after placement, and the stability of the steel during testing is guaranteed. Further explanation; The reinforcement assembly includes a first clamping plate 13 and a second clamping plate 14 movably sleeved within a fixed plate. A second limiting plate 15 corresponding to the steel is integrally connected to both the first clamping plate 13 and the second clamping plate 14. An anti-slip layer 16 in contact with the steel is embedded in the second limiting plate 15. The steel is limited by the second limiting plate 15 driven by the first clamping plate 13 and the second clamping plate 14 from both sides. The anti-slip layer 16 in the second limiting plate 15 increases the friction between the anti-slip layer 16 and the steel, thus preventing the steel from slipping during testing. A fixing bolt is detachably installed between the first clamping plate 13 and the second clamping plate 14, and a limiting frame 17 is detachably extended from the second limiting block 8 into the first clamping plate 13 and the second clamping plate 14. The second limiting plate 15 is an arc-shaped structure adapted to the steel. By setting the second limiting plate 15 to an arc-shaped structure adapted to the steel, the contact area between the second limiting plate 15 and the steel is increased, so that the steel extending into the second limiting block 8 can be effectively limited by the second limiting plate 15. It should be noted that the limiting frame 17 is a T-shaped structure, and according to the instruction manual... Figure 3 As shown, the two second limiting blocks 8 are located on both sides of the first limiting block 7; The first limiting plate 12 can limit and fix the steel extending into the placement hole 9, and the second limiting plate 15 can limit the steel extending into the second limiting block 8, so that the two ends of the steel can be effectively fixed after placement, thereby ensuring that the steel will not slip or flip during inspection, effectively improving the efficiency and level of steel inspection. Further explanation; The protective assembly includes a bracket 18 fixedly installed on the connecting ear 2, and a telescopic rod 19 fixedly installed on the bracket 18. The telescopic rod 19 is an electric push rod. The output end of the telescopic rod 19 is integrally connected to a sealing cover 20 for sealing the steel. A detection head for detecting the steel is fixedly installed inside the sealing cover 20. It should be noted that the detection head is capable of detecting the steel, which is existing technology. The downward movement of the output end of the telescopic rod 19 allows the sealing cover 20 to seal the steel being tested, preventing debris or steel fragments from splashing onto surrounding operators when the steel breaks during testing, thus ensuring operator safety during operation. A transparent observation window is provided on one side of the sealing cover 20, and the sealing cover 20 has a U-shaped structure with an open bottom. Both the bracket 18 and the sealing cover 20 have limiting holes for limiting the steel. The limiting holes can guide the steel extending outside the processing table 1. After the processing table 1 is opened through the sealing cover 20, the operator can collect and clean the debris on the processing table 1 to maintain the cleanliness of the processing table 1.

[0022] The functional principle of this invention can be explained through the following operational methods: The steel to be inspected is extended through the placement hole 9 into the first limiting block 7 and the second limiting block 8, so that the position to be inspected is located below the inspection head; The manual traction handle is turned, which drives the lead screw 10 to rotate, causing the lead screw 10 to move the nut 11 up and down. When the nut 11 moves the first limiting plate 12 downward, it can limit steel of different specifications within the placement hole 9, and use the limiting bolt to fix the handle and the first limiting block 7. Manually press the first clamping plate 13 and the second clamping plate 14 within the second limiting block 8 so that the second limiting plate 15 and the anti-slip layer 16 surround the steel from both sides, and use fixing bolts to fix the first clamping plate 13 to the first clamping plate 14. Install the limiting frame 17 so that the limiting frame 17 can extend into the first clamping plate 13 and the second clamping plate 14, thereby limiting the first clamping plate 13 and the second clamping plate 14 on the second limiting block 8. The output end of the telescopic rod 19 moves down, causing the telescopic rod 19 to drive the sealing cover 20 to move down. After the sealing cover 20 moves down, it can allow both ends of the steel to slide in the limiting hole while sealing the first limiting block 7, the second limiting block 8 and the steel. The operator installs two fixing blocks 6 at the middle position of the guide rod 3 and performs strength testing on the steel through the detection head; During strength testing, the steel will deform at the pressure point. Under the action of deformation, the steel will pull on the second limiting block 8 and the second limiting plate 15, causing the second limiting block 8 and the second limiting plate 15 to move the first limiting block 7. This allows the first limiting block 7, the second limiting block 8, the connecting rod 5 and the guide block 4 to slide on the guide rod 3. After the steel is inspected, the inspection head returns to the initial position, the telescopic rod 19 drives the sealing cover 20 back to the initial position, and the limit bolt, fixing bolt, and limit frame 17 are disassembled. The operator stands on one side of the processing table 1 and extracts the steel, moves the first limit block 7 and the second limit block 8 to the initial position, and places the new steel to be inspected in the placement hole 9.
