Description

Technical Field

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

[0002] Steel structures, as an indispensable structural form in modern construction engineering, are becoming increasingly important. They are structures mainly made of stainless steel plates and are composed of steel materials such as steel profiles and steel plates through processing, connection, and installation. They are one of the key types of engineering building structures today. Hardness testing in steel structure production is an important quality control step, which helps ensure that the mechanical properties of the materials meet the design requirements.

[0003] Existing patent CN222784431U discloses a hardness testing device for steel structure production, belonging to the field of steel structure production technology. It includes a workbench with a set of support rods and side plates. A set of movable lead screws is arranged between the support rods and side plates. A connecting plate is slidably mounted on the outer periphery of the movable lead screws. A second movable lead screw is rotatably mounted on the connecting plate. A telescopic rod is slidably mounted on the outer periphery of the second movable lead screw. A hardness testing head is fixedly mounted at the bottom end of the telescopic rod. The workbench has a groove, inside which a bidirectional movable lead screw is rotatably mounted. A set of fixing blocks is slidably mounted on the outer periphery of the bidirectional movable lead screw. Several fastening components are mounted on the fixing blocks. A set of elastic structures is located near the side plates, and the elastic structures are fixedly connected by elastic straps. This device allows the hardness testing head to freely test different parts of the steel structure, facilitating comprehensive and accurate measurement of the steel structure. It also allows for the adjustment of the fastening components to secure uneven steel structures.

[0004] Based on the search of the aforementioned patents and in conjunction with the existing testing devices, it was found that although the aforementioned testing devices can perform hardness testing on steel structures, during the testing process, they use a bidirectional moving screw to position and fix the steel structure. The bidirectional moving screw is prone to rotation due to vibration, which can affect the fixing effect on the steel structure and thus affect the test results. In addition, if the steel structure is damaged during the test, debris may fly out, which can easily cause injury. Utility Model Content

[0005] The purpose of this utility model is to provide a steel structure testing device to solve the problems mentioned in the background art. Although the existing testing devices can test the hardness of steel structures, they are prone to rotation due to vibration and other factors when positioning and fixing the steel structure during testing. This affects the fixing effect on the steel structure and thus the test results. In addition, if the steel structure is damaged during testing, debris may fly, which may cause injury.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure inspection device, including an inspection platform, a positioning component on the top of the inspection platform, and a protective component on the top of the inspection platform;

[0007] The positioning component includes sliding openings on both sides of the top of the testing platform, sliding blocks connected to the sliding openings, a positioning plate fixedly connected to the top of the sliding blocks, a bidirectional screw connected to the sliding blocks, a groove on one end of the bidirectional screw, a pull rod connected to the groove, a first spring fixedly connected to one end of the pull rod, a rotating plate fixedly connected to the other end of the pull rod, support rods fixedly connected to both sides of the rotating plate, two circumferentially arranged insertion holes on one end of the bidirectional screw, a locking rod fixedly connected to both sides of the rotating plate, and multiple circumferentially arranged locking holes on one side of the testing platform. The bidirectional screw is rotatably connected to the testing platform and screwed to the sliding blocks.

[0008] Preferably, the protective component includes a protective cover fixedly connected to the top of the testing platform, a movable opening on one side of the top of the protective cover, a protective plate connected to the movable opening, a sliding groove on both sides of the movable opening, a sliding rod connected to the sliding groove, a second spring fixedly connected to one end of the sliding rod, a protrusion fixedly connected to the other end of the sliding rod, and two recesses on both sides of the protective plate. The protrusion is inserted into the recess, the sliding rod is slidably connected to the sliding groove, and the protective plate is inserted into the movable opening.

[0009] Preferably, a fixing plate is fixedly connected to both sides of the bottom of the testing platform, and a pull-out opening is provided on one side of the fixing plate. A pull-out plate is inserted into the pull-out opening, and a waste bin is fixedly connected between the two pull-out plates.

[0010] Preferably, a strip groove is provided on one side of the slide rod, and a strip plate is fixedly connected to the inner wall of the slide groove, and the strip plate is slidably connected to the strip groove.

[0011] Preferably, a cylinder is fixedly connected to the top of the protective cover, a connecting seat is fixedly connected to the output end of the cylinder, and a detection head is fixedly connected to the bottom of the connecting seat.

[0012] Preferably, corrugated covers are fixedly connected to both sides of the sliding block, and the other end of the corrugated cover is fixedly connected to the inner wall of the sliding port.

[0013] Preferably, a movable handle is fixedly connected to each side of the waste bin, and the movable handle is U-shaped.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up a testing platform and positioning components, pulling the rotating plate can drive the pull rod and locking rod to move. The pull rod can drive the first spring to deform, and the locking rod moves away from the current lock hole, which can release the double-ended screw. The rotating plate can be rotated, and due to the presence of the support rod, the double-ended screw can be rotated synchronously, thereby controlling the movement of the positioning plate and positioning and fixing the steel structure. The first spring resets and drives the locking rod to re-engage in the lock hole, which can lock the double-ended screw and prevent it from rotating, thereby improving the positioning effect of the steel structure, improving the accuracy of the test results, and greatly improving the practicality of the device.

[0016] 2. With the addition of protective components, when the protective plate moves upward, the protrusion drives the sliding rod to compress the second spring, causing it to deform. The second spring then returns to its original position, allowing the protrusion to engage in the recess at the lower part of the protective plate, thus securing the protective plate and facilitating the removal and placement of the steel structure. When the protective plate moves downward, the protrusion engages in the recess at the upper part, preventing the protective plate from moving arbitrarily. The protective plate and protective cover can enclose the testing platform, preventing debris from flying out during testing and protecting the workers. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model provides a technical solution: a steel structure testing device, including a testing platform 1, a positioning component on the top of the testing platform 1, and a protective component on the top of the testing platform 1. The positioning component includes sliding openings 21 respectively opened on both sides of the top of the testing platform 1, a sliding block 22 connected to the sliding openings 21, a positioning plate 23 fixedly connected to the top of the sliding block 22, a bidirectional screw 24 connected to the sliding block 22, a groove 25 opened at one end of the bidirectional screw 24, a pull rod 26 connected to the groove 25, a first spring 27 fixedly connected to one end of the pull rod 26, a rotating plate 28 fixedly connected to the other end of the pull rod 26, a support rod 29 fixedly connected to both sides of the rotating plate 28, and a support rod 29 opened on the bidirectional screw 24. The rod 24 has two circumferentially arranged insertion holes 30 at one end, a locking rod 31 fixedly connected to both sides of the rotating plate 28, and multiple circumferentially arranged locking holes 32 on one side of the testing platform 1. The support rod 29 is slidably connected to the insertion holes 30, the bidirectional screw 24 is rotatably connected to the testing platform 1, the bidirectional screw 24 is screwed to the sliding block 22, the sliding block 22 is slidably connected to the sliding port 21, the pull rod 26 is slidably connected to the pull groove 25, and the locking rod 31 is inserted into the locking hole 32. By pulling the rotating plate 28, the locking rod 31 and the pull rod 26 can be moved. The movement of the pull rod 26 can deform the first spring 27, and the movement of the locking rod 31 can disengage from the current locking hole 32, which can release the bidirectional screw 24. Due to the support rod 29 The presence of the rotating plate 28 allows the bidirectional screw 24 to rotate, which facilitates the movement of the two positioning plates 23 and enables the positioning and release of the steel structure. The reset of the first spring 27 can reset the locking rod 31, causing it to re-engage into the locking hole 32, thus locking the bidirectional screw 24 and preventing its rotation from affecting the positioning stability. Fixed plates 51 are fixedly connected to both sides of the bottom of the testing platform 1. A pull-out opening 52 is provided on one side of the fixed plate 51, and a pull-out plate 53 is inserted into the pull-out opening 52. A waste bin 54 is fixedly connected between the two pull-out plates 53. The pull-out plate 53 can be inserted into the pull-out opening 52 to fix the waste bin 54 to the testing platform 1. 54 facilitates the collection of debris falling into the sliding port 21, preventing it from falling directly to the ground and polluting the environment. Corrugated covers 81 are fixedly connected to both sides of the sliding block 22, and the other end of the corrugated cover 81 is fixedly connected to the inner wall of the sliding port 21. When the sliding block 22 slides laterally, it can squeeze the corrugated cover 81 to deform it. The corrugated cover 81 can cover the bidirectional screw 24, preventing debris from falling to the outside of the bidirectional screw 24 and causing damage, thus ensuring its operational stability. Moving handles 91 are fixedly connected to both sides of the waste bin 54. The moving handles 91 are U-shaped, which facilitates the movement of the waste bin 54 and improves its portability.

[0026] Please see Figure 1 , Figure 2 , Figure 5 as well as Figure 6The protective components include a protective cover 41 fixedly connected to the top of the testing platform 1, a movable opening 42 on one side of the top of the protective cover 41, a protective plate 43 connected to the movable opening 42, sliding grooves 44 respectively opened on both sides of the movable opening 42, a sliding rod 45 connected to the sliding grooves 44, a second spring 46 fixedly connected to one end of the sliding rod 45, a protrusion 47 fixedly connected to the other end of the sliding rod 45, and two recesses 48 respectively opened on both sides of the protective plate 43. The protrusion 47 is inserted into the recesses 48, and the sliding rod 46 is inserted into the recesses 48. 5 is slidably connected to the slide groove 44, and the protective plate 43 is inserted into the moving port 42. The protective cover 41 and the protective plate 43 can be made of polycarbonate, which is transparent and easy to observe. The protective plate 43 can move vertically. When the protective plate 43 moves inside the protective cover 41, the protrusion 47 can disengage from the current recess 48. The protrusion 47 can drive the slide rod 45 to move. The movement of the slide rod 45 can compress the second spring 46 to deform it. When the protrusion 47 contacts the recess 48, the second spring 46 can return to its original position and drive the protrusion 47 to move. 47 is inserted into the notch 48 to fix the protective plate 43 and prevent it from moving. Moving the protective plate 43 upwards makes it easier to pick up and place the steel structure, while moving it downwards closes the protective cover 41 to prevent debris from flying and injuring people. A strip groove 61 is provided on one side of the sliding rod 45. A strip plate 62 is fixedly connected to the inner wall of the groove 44. The strip plate 62 is slidably connected to the strip groove 61. When the sliding rod 45 moves, it can move the strip plate 62, allowing the strip plate 62 to move within the strip groove 61. The sliding mechanism 1, through the strip plate 62 and the strip groove 61, prevents the slide rod 45 from rotating, thereby preventing the second spring 46 from rotating and being damaged. A cylinder 71 is fixedly connected to the top of the protective cover 41, and a connecting seat 72 is fixedly connected to the output end of the cylinder 71. A detection head 73 is fixedly connected to the bottom of the connecting seat 72. The cylinder 71 can be of model C95. When the cylinder 71 is working, it can push the connecting seat 72 to move vertically, which in turn facilitates the vertical movement of the detection head 73, making it easier to inspect the steel structure.

[0027] Working principle: During operation, pulling the protective plate 43 upwards causes the protrusion 47 to disengage from the current recess 48. The movement of the protrusion 47 moves the sliding rod 45, which in turn compresses the second spring 46, causing it to deform. When the protrusion 47 contacts the recess 48 below the protective plate 43, the second spring 46 resets, causing the protrusion 47 to engage with the recess 48, thus securing the protective plate 43. The steel structure can then be placed on top of the testing platform 1. Next, the protective plate 43 is lowered to reset its position. Then, pulling the rotating plate 28 causes the pull rod 26 and locking rod 31 to move. The movement of the pull rod 26 deforms the first spring 27, and the locking rod 31 moves. The device can be disengaged from the current lock hole 32, and then the rotating plate 28 can be rotated. Due to the presence of the support rod 29, the rotation of the rotating plate 28 can drive the bidirectional screw 24 to rotate, which in turn can drive the two sliding blocks 22 to move towards the middle, and then drive the positioning plate 23 to move, thus fixing the steel structure. When the rotating plate 28 is released, the first spring 27 resets, driving the locking rod 31 to reset, so that it is locked into the lock hole 32, locking the bidirectional screw 24 and preventing it from rotating. The operation of the cylinder 71 can push the detection head 73 down to perform hardness testing on the steel structure. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0028] 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.
