Description

Technical Field

[0001] This utility model relates to the field of steel bar bending detection technology, and in particular to a steel bar quality detection device for construction projects. Background Technology

[0002] Reinforcing bars refer to steel used in reinforced concrete and prestressed reinforced concrete. Their cross-section is circular, sometimes square with rounded corners. Reinforcing bars for reinforced concrete refer to straight or coiled steel bars used for reinforcing concrete. They are available in two shapes: plain round bars and deformed bars, and are delivered in straight bars or coils. Before being used in on-site construction, reinforcing bars are often subjected to a bending test to assess their bending resistance. This test requires a reinforcing bar bending test device.

[0003] Chinese patent document CN221745762U discloses a concrete rebar testing device for construction engineering quality testing. The device features movable blocks on the threaded surfaces of both sides of a bidirectional screw rod. Each movable block has a threaded through hole at its center, and these holes are threadedly connected to the threads on both sides of the bidirectional screw rod. A guide block is positioned below each movable block, with a through hole at its center. A guide rod passes through this through hole, and its two ends are fixed to the inner walls of the mounting groove. A connecting column is fixed above each movable block, and a fixing block is fixed to the upper end of each connecting column. This invention can test rebars of different lengths, improving the device's applicability.

[0004] The existing technology has the following problems:

[0005] While the aforementioned device can accommodate rebars of varying lengths, the lack of fixed ends during bending tests makes the rebar prone to detaching from the fixing blocks, affecting the accuracy of the test and limiting its practicality. Furthermore, the device requires manual collection of the bent rebar, increasing labor costs. Additionally, manual removal of the rebar with both hands facing the hydraulic cylinder poses a safety hazard. Utility Model Content

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 and Figure 5 As shown, a construction engineering steel reinforcement quality testing device includes a base 1, a limiting component 2 is movably connected to the upper front of the base 1, a flipping and unloading component 3 is fixedly connected to the left side of the limiting component 2, and a bending detection mechanism 4 is fixedly installed at the upper rear of the base 1.

[0028] The limiting component 2 includes a reverse double threaded rod 21. The upper front part of the base 1 is provided with an installation groove 22. The left and right ends of the reverse double threaded rod 21 are rotatably connected to the left and right parts of the inner wall of the installation groove 22. The left end of the reverse double threaded rod 21 passes through the left part of the base 1 and is fixedly installed with a turntable 23. The left and right parts of the outer wall of the reverse double threaded rod 21 are threadedly connected with drive plates 24. The upper middle part of the two drive plates 24 is fixedly installed with a support 25. The upper middle part of the two supports 25 is rotatably connected with a rotating shaft 26. The middle part of the outer wall of the two rotating shafts 26 is fixedly sleeved with a connecting plate 27. The upper end of the two connecting plates 27 is fixedly installed with a fixing frame 28. The bottom of the inner wall of the two fixing frames 28 is fixedly installed with a support seat 29. The top of the inner wall of the two fixing frames 28 is movably connected with a pressing fixing mechanism.

[0029] The flipping and unloading assembly 3 includes a gear 31. The outer left side of the left rotating shaft 26 is fixedly connected to the inner wall of the gear 31. L-shaped frames 32 are fixedly installed on the left side of the front and rear sides of the left support 25. A lead screw 33 is rotatably connected to the left side of the opposite side of the two L-shaped frames 32. A moving plate 34 is threadedly connected to the outer wall of the lead screw 33. A motor 35 is fixedly installed on the left side of the rear side of the rear L-shaped frame 32. The output end of the motor 35 passes through the rear of the rear L-shaped frame 32 and is fixedly connected to the rear end of the lead screw 33. A rack 36 is fixedly installed on the upper end of the moving plate 34. The upper end of the rack 36 meshes with the outer surface of the gear 31. A connecting mechanism is fixedly installed on the opposite ends of the two rotating shafts 26.

[0030] The limiting component 2 can limit the movement of steel bars of different sizes. Furthermore, the left and right ends of the steel bars can be fixed between the corresponding support 29 and clamping seat 212, preventing the steel bars from falling off or loosening when the bending detection mechanism 4 bends them forward. This enhances practicality and improves the equipment's detection accuracy. The flipping unloading component 3 allows manual loosening of the left and right ends of the steel bars after bending. When the motor 35 starts, the two fixing frames 28 can be flipped forward via the two rotating shafts 26, automatically pouring the steel bars between the two receiving slots 213 into the collection box 313. This facilitates the unified collection of bent materials after inspecting the same batch of steel bars, eliminating the need for manual unloading, saving manpower, and ensuring high safety.

[0031] The bending detection mechanism 4 includes a mounting plate, a hydraulic cylinder, a push plate, a sensor, a contact head, and two telescopic rods, which is an existing mechanism. The lower end of the mounting plate is fixedly installed to the upper rear part of the base 1. The hydraulic cylinder is installed at the front of the mounting plate, and its output end is fixedly installed to the rear middle of the push plate. The sensor is installed at the front middle of the push plate, and its output end is fixedly connected to the rear end of the contact head. The two telescopic rods are distributed to the left and right of the hydraulic cylinder, and their output ends are fixedly connected to the rear left and right sides of the push plate. When the hydraulic cylinder is activated, the push rod drives the contact head forward, and the contact head bends the horizontally placed steel bar. The sensor can record data and transmit the signal to the display mechanism on the upper left of the base 1.

[0032] like Figure 3 As shown, the inner wall of the mounting groove 22 is provided with sliding grooves 210 at both the front and rear sides, and the front and rear sides of the two drive plates 24 are slidably connected to the left and right sides of the inner wall of the two sliding grooves 210.

[0033] The slide 210 can guide the drive plate 24.

[0034] like Figure 4 As shown, the pressing and fixing mechanism includes two adjusting screws 211. The outer walls of the two adjusting screws 211 are threadedly connected to the inner walls of the upper middle part of the two fixing brackets 28. The lower ends of the two adjusting screws 211 are rotatably connected to pressing seats 212. The two pressing seats 212 and the two support seats 29 are respectively provided with arc-shaped receiving grooves 213 on their opposite sides.

[0035] When the two adjusting screws 211 are rotated, they can drive the two clamping seats 212 to move down, which makes it easier to clamp and fix the steel bars in the bottom receiving groove 213.

[0036] like Figure 4 As shown, guide rods 214 are slidably connected to the inner walls of the left and right sides of the upper ends of the two fixed brackets 28, and the lower ends of the four adjacent guide rods 214 are fixedly connected to the left and right sides of the upper ends of the two clamping seats 212.

[0037] The guide rod 214 can guide the clamping seat 212.

[0038] like Figure 5 As shown, a limiting rod 37 is fixedly installed at the bottom position of the left side of the two L-shaped frames 32, and the inner wall of the bottom of the movable plate 34 is slidably connected to the outer side of the limiting rod 37.

[0039] The limit rod 37 guides the moving plate 34.

[0040] like Figure 5 As shown, the connecting assembly includes a fixed sleeve 38 and a connecting rod 39. The left end of the fixed sleeve 38 is fixedly connected to the right end of the left rotating shaft 26, and the right end of the connecting rod 39 is fixedly connected to the left end of the right rotating shaft 26. Guide grooves 310 are provided on the front and rear parts of the inner wall of the fixed sleeve 38, and slide bars 311 are fixedly installed on the front and rear parts of the outer wall of the connecting rod 39. The side of the two slide bars 311 that is far away from each other is slidably connected to the inner wall of the two guide grooves 310.

[0041] When the left rotating shaft 26 rotates, it can drive the right rotating shaft 26 to rotate accordingly through the fixed sleeve 38. The cooperation between the slide bar 311 and the guide groove 310 not only transmits the rotational force, but also provides a limiting and guiding effect on the movement of the connecting rod 39.

[0042] like Figure 2 and Figure 3 As shown, a mounting bracket is fixedly installed at the lower front of the base 1, and a container frame 312 is fixedly installed at the front end of the mounting bracket. A collection box 313 is slidably connected to the left and right sides of the inner wall of the container frame 312. A handle 314 is fixedly installed on the top of the left and right sides of the collection box 313.

[0043] When the two fixed frames 28 flip forward, the steel bars in the receiving groove 213 will fall into the collection box 313 due to gravity, eliminating the need for manual unloading and enabling the collection and summarization of all bent steel bars from the same batch.

[0044] The working principle of this utility model is as follows: During use, the turntable 23 is rotated according to the length of the reinforcing bar. The turntable 23 drives the reverse double-threaded rod 21 to rotate. The two drive plates 24, through threaded connection with the reverse double-threaded rod 21, drive the two fixed frames 28 to move closer together. At this time, the connecting rod 39 slides within the fixed sleeve 38. The worker places the reinforcing bar in the receiving grooves 213 on the two support seats 29, and then rotates the two adjusting screws 211. These screws drive the two clamping seats 212 to move downwards, facilitating the clamping and fixing of the reinforcing bar in the receiving grooves 213. The bending detection mechanism 4 is then activated, and its output end bends the horizontally placed reinforcing bar forward, causing the middle of the reinforcing bar to bend while its left and right sides remain horizontal. The bending detection mechanism 4 transmits the received detection signal to the display mechanism on the upper left side of the base 1 to obtain the data.

[0045] After the steel bars are bent, the worker rotates the two adjusting screws 211 in the opposite direction to move the two clamping seats 212 away from the two support seats 29. The motor 35 is turned on, and its output end drives the lead screw 33 to rotate. The moving plate 34 moves backward through the threaded connection with the lead screw 33. The gear 31 drives the rotating shaft 26 to rotate through the meshing with the rack 36. The two rotating shafts 26 rotate synchronously due to the connection relationship between the fixed sleeve 38 and the connecting rod 39, thereby causing the two fixed frames 28 to flip forward, and then the bent steel bars are poured into the collection box 313. After the same batch of steel bars has been inspected, the robotic arm can be used to slide the collection box 313 and the container frame 312 apart through the handle 314.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
