Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering testing technology, specifically relating to a device for testing the strength of steel bars in water conservancy engineering. Background Technology

[0002] Quality inspection of water conservancy projects, or simply quality inspection, refers to the activities conducted by water conservancy project quality inspection units, in accordance with relevant national laws, regulations, and standards, to inspect, test, or measure the physical structure of water conservancy projects and the raw materials, intermediate products, metal structures, and electromechanical equipment used in them, and to compare the results with relevant standards and requirements to determine whether the project quality is up to standard. Reinforcing steel strength quality inspection mainly involves testing the reinforcing steel in terms of yield point, tensile strength, and bending tests. However, current testing technologies still have the following technical problems:

[0003] (1) When testing the strength of steel bars, it is usually necessary to test multiple steel bars and manually insert multiple steel bars, which is not only troublesome but also tedious.

[0004] (2) At present, steel bars of fixed length are usually fixed. However, when fixing longer or shorter steel bars, the fixing may be unstable or only one end can be fixed. In water conservancy projects, the length of steel bars may vary, which reduces their application range.

[0005] Therefore, how to solve the above-mentioned technical problems simultaneously becomes the key technical problem to be addressed in this solution. Utility Model Content

[0006] The purpose of this invention is to provide a steel reinforcement strength testing device for water conservancy projects, which solves the technical problem of how to automatically test multiple steel reinforcements in sequence, and is also applicable to steel reinforcements of different lengths.

[0007] A steel reinforcement strength testing device for water conservancy projects includes a support frame, a moving mechanism on the support frame, a testing device connected below the moving mechanism, and multiple parallel conveying mechanisms I and multiple parallel conveying mechanisms II arranged below the testing device. Both conveying mechanisms I and conveying mechanisms II are slidably arranged in a track assembly.

[0008] The first and second transmission mechanisms are arranged in parallel to each other, and their longitudinal center lines are parallel to each other.

[0009] The conveying mechanism includes a conveyor belt, power rollers supported at both ends of the conveyor belt, multiple baffles arranged at equal intervals on the outer side of the conveyor belt, a motor connected to one of the power rollers, and a support plate disposed on the inner side of the conveyor belt. The two power rollers are rotatably connected to the fixed frame, and the two ends of the support plate are fixedly connected to the fixed frame.

[0010] The second conveying mechanism includes a second conveyor belt, two power rollers supported at both ends of the second conveyor belt, multiple baffles arranged at equal intervals on the outer side of the second conveyor belt, a second motor connected to one of the power rollers, and a second support plate disposed on the inner side of the second conveyor belt. The two power rollers are rotatably connected to the second fixed frame, and the two ends of the first support plate are fixedly connected to the second fixed frame.

[0011] The track assembly includes a track one and a track two arranged in parallel to each other, and an intermediate track arranged in parallel between the track one and the track two. The bottom end of the fixing frame one is movably disposed in the track one and the intermediate track by a roller one.

[0012] The bottom end of the second fixed frame is movable in the second track and the intermediate track via the second roller.

[0013] The moving mechanism includes a horizontal rail fixed to the top of the support, meshing teeth fixed to the upper end of the horizontal rail, a movable seat movably arranged on the horizontal rail, a drive shaft rotatably connected to the movable seat, a gear coaxially arranged on the drive shaft, and a drive motor drivenly connected to the drive shaft, wherein the gear meshes with the meshing teeth.

[0014] An opening groove is provided on the outer side of the transverse track, and the inner side of the movable seat is movably embedded in the opening groove.

[0015] The testing equipment can be any one of non-destructive testing equipment or a bending tester. The operating principles of non-destructive testing equipment and bending testers are existing technologies, and their connection and contact methods with the reinforcing bars in this solution can be understood and operated by those skilled in the art, and will not be described in detail here.

[0016] It should be noted that the bending test method uses bending to test the strength of steel bars. It can detect the bending static properties of steel bars, including bending stress and bending modulus. Therefore, by controlling the downward movement of the force-applying structure on the bending test machine to compress and bend the steel bars, the strength of the steel bars can be tested.

[0017] The testing equipment can be equipped with pressure sensors, force sensors, or load sensors according to specific testing needs. This equipment can detect the magnitude of the force exerted on the reinforcing steel when it bends, thereby determining the steel's strength. Non-destructive testing equipment is existing technology and will not be described in detail here.

[0018] An inclined plate is provided on the outer side of the fixed frame, and the bottom end of the inclined plate faces the direction of movement of the conveyor belt.

[0019] A robotic arm is installed at the outer end of the first conveyor belt, and a robotic arm is installed at the outer end of the second conveyor belt.

[0020] For any technical details not described in detail in this solution, refer to the accompanying drawings and the conventional understanding of those skilled in the art, and use existing technologies to solve the problem. The principle is that as long as this solution is implemented, no specific limitations are imposed. This is hereby stated.

[0021] This utility model achieves the following significant effects:

[0022] (1) The steel bars placed on the first baffle are transported to the bottom of the testing equipment through the action of the first conveyor belt for testing; after the testing is completed, they are put into the second conveyor belt and carried out through the second conveyor belt. It is convenient and fast, with a high level of automation, and realizes the automatic placement, transmission and testing process of multiple steel bars.

[0023] (2) There are multiple conveying mechanisms, which are arranged in parallel to each other. On the one hand, they can be used for steel bars of different lengths. By adjusting the spacing between adjacent conveying mechanisms, the length of the steel bar can be adaptively adjusted. On the other hand, the steel bar part between two adjacent conveying mechanisms is in contact with the detection equipment for detection. The two adjacent stops together serve as limit supports.

[0024] (3) It is equipped with track one, track two and intermediate track, so that the first and second conveyor mechanisms can move synchronously, which is efficient and fast. Attached Figure Description

[0030] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0031] See Figures 1-4 A steel reinforcement strength testing device for water conservancy projects includes a support 1, a moving mechanism 6 is provided on the support 1, a testing device 5 is connected below the moving mechanism 6, and a plurality of parallel conveying mechanisms 1 2 and a plurality of parallel conveying mechanisms 2 8 are provided below the testing device 5. The conveying mechanisms 1 2 and the conveying mechanisms 2 8 are slidably arranged in a track assembly.

[0032] The first transmission mechanism 2 and the second transmission mechanism 8 are arranged in parallel to each other, and their longitudinal center lines are parallel to each other.

[0033] The conveying mechanism 2 includes a conveyor belt 21, power rollers supported at both ends of the conveyor belt 21, multiple baffles 22 evenly spaced on the outer side of the conveyor belt 21, a motor 23 driven and connected to one of the power rollers, and a support plate 24 disposed on the inner side of the conveyor belt 21. The two power rollers are rotatably connected to a fixed frame 25, and both ends of the support plate 24 are fixedly connected to the fixed frame 25. The conveyor belt may be a metal conveyor mesh.

[0034] The function of the support plate 24 is to support the conveyor belt 21 and prevent it from sinking under the action of gravity.

[0035] The second conveyor mechanism 8 includes a second conveyor belt 81, two power rollers 81 respectively supported at both ends of the second conveyor belt 81, multiple baffles 82 equally spaced on the outside of the second conveyor belt 81, a motor 84 driven and connected to one of the power rollers 81, and a support plate 83 set on the inside of the second conveyor belt 81. The two power rollers 82 are rotatably connected to the fixed frame 2 respectively, and the two ends of the support plate 83 are fixedly connected to the fixed frame 2 respectively.

[0036] The function of support plate 283 is to support conveyor belt 281 and prevent it from sinking under the action of gravity.

[0037] The track assembly includes a track 3 and a track 7 arranged in parallel to each other, and an intermediate track arranged in parallel between the track 3 and the track 7. The bottom end of the fixing frame 25 is movably positioned in the track 3 and the intermediate track via a roller.

[0038] The bottom end of the fixed frame 2 is moved and set in the track 2 7 and the intermediate track by the roller 2.

[0039] Therefore, both the first conveyor mechanism 2 and the second conveyor mechanism 8 can move and adjust back and forth in the intermediate track simultaneously.

[0040] The moving mechanism 6 includes a horizontal rail 4 fixed to the top of the support 1, meshing teeth fixed to the upper end of the horizontal rail 4, a moving seat 61 movably arranged on the horizontal rail 4, a drive shaft 63 rotatably connected to the moving seat 61, a gear 64 coaxially arranged on the drive shaft 63, and a drive motor 62 drivenly connected to the drive shaft 63. The gear 64 is meshed with the meshing teeth.

[0041] An opening groove 41 is provided on the outer side of the transverse track 4, and the inner side of the movable seat 61 is movably embedded in the opening groove 41.

[0042] Under the action of the drive motor 62, the gear 64 is driven to rotate, thereby driving the moving seat 61 to move, and driving the detection device 5 to reciprocate.

[0043] The testing equipment 5 is any one of non-destructive testing equipment or bending tester.

[0044] An inclined plate 251 is provided on the outer side of the fixed frame 25, with the bottom end of the inclined plate 251 facing the direction of movement of the conveyor belt 21. The function of the inclined plate 251 is to allow the steel bars to slide directly onto the inclined plate 251 after sliding off the conveyor belt 21, and then slide off the inclined plate 251 onto the conveyor belt 81, thus acting as a buffer.

[0045] A robotic arm is installed at the outer end of conveyor belt 21, and a robotic arm is installed at the outer end of conveyor belt 81. Both robotic arms are existing technologies and will not be described in detail here, nor will they be shown in the attached drawings.

[0046] The working process of this utility model is as follows:

[0047] Through the action of conveyor belt 21, the robotic arm transports the steel bars placed on the stop bar 22 to the bottom of the testing device 5 for testing. After the testing is completed, as the conveyor belt 21 reaches its end, it automatically slides into the conveyor belt 81 under the buffering effect of the inclined plate 251 and is carried out by the conveyor belt 81. It is convenient, fast and has a high level of automation, realizing the automatic placement, transmission and testing process of multiple steel bars.

[0048] The spacing between adjacent retaining strips 1 and 22 is smaller than the spacing between adjacent retaining strips 2 and 82, which makes it easier for the reinforcing bars to accurately enter the retaining strips 2 and 82.

[0049] The conveying mechanism 2 has multiple components arranged in parallel to each other. On the one hand, it can be used for steel bars of different lengths. By adjusting the spacing between adjacent conveying mechanisms 2, it can be adaptively adjusted according to the length of the steel bar. On the other hand, the steel bar portion between two adjacent conveying mechanisms 2 comes into contact with the detection device 5 for detection. The two adjacent baffles 22 serve as limiters.

[0050] The system is equipped with track 1 (3), track 2 (7), and an intermediate track, enabling conveyor mechanism 1 (2) and conveyor mechanism 2 (8) to move synchronously, efficiently and quickly. Specifically, the equipment can be manually pushed to move simultaneously on each track.

[0051] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
