Description

Technical Field

[0001] This utility model relates to the field of rebar detection technology, and in particular to a rebar detection device for road and bridge construction. Background Technology

[0002] Roads and bridges generally consist of several major parts, including roadbed, pavement, bridges, tunnels, and traffic engineering facilities. Reinforcing steel refers to steel used in reinforced concrete and prestressed reinforced concrete. Reinforcing steel for reinforced concrete refers to straight or coiled steel used for reinforcing concrete, and its shape is divided into plain round steel bars and deformed steel bars. It is delivered in straight bars and coils. In the construction of roads and bridges, reinforcing steel bars are used to strengthen the strength of the main structure of the bridge. Before use, reinforcing steel bar testing devices are used to test the data of the reinforcing steel bars.

[0003] Existing technologies, such as the utility model patent with publication number CN214952660U, disclose a rebar testing device for road and bridge construction. This patent employs a workbench, control box, anti-slip support legs, a chute, a tensile testing device, a torsion testing device, a cold bending testing device, and an operating box. The workbench has a rectangular structure with the control box installed at the bottom center. The control box is surrounded by equidistantly and symmetrically distributed support legs. A rectangular chute is opened on the rear side of the top of the workbench. The tensile testing device is installed inside the chute. The torsion testing device is installed at the left end of the tensile testing device. The cold bending testing device is installed at the front end of the tensile testing device. The operating box is installed at the front end of the cold bending testing device. This utility model, through its rational design, can effectively increase the diversity of test data by performing tensile strength testing, torsion testing, and cold bending strength testing on rebar. It also reduces testing costs by being multifunctional. It solves the problem that currently, rebar often needs to be tested for strength and other properties before construction to ensure the quality of buildings, but often a single machine can only test one indicator, which is very inconvenient. Therefore, a new type of rebar testing equipment capable of multiple tests is needed.

[0004] In their daily work, the inventors discovered that when using testing devices to test reinforcing bars, existing testing devices, such as those mentioned above, use clamping structures of fixed sizes. Since the specifications of the reinforcing bars used in actual use are adjusted according to the stress points, resulting in a wide variety of reinforcing bar specifications used in projects, it is difficult to apply a fixed-size clamping structure to reinforcing bars of different specifications, leading to poor applicability of the device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the specifications of reinforcing bars used in engineering are numerous, making it difficult to apply a fixed-size clamping structure to reinforcing bars of different specifications, resulting in poor applicability of the device. Therefore, this invention proposes a reinforcing bar detection device for road and bridge construction.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a rebar inspection device for road and bridge construction, comprising a support leg, a table, and a clamping assembly. The table is mounted on the upper surface of the support leg, and a driving mechanism is mounted on the upper surface of the table. A push plate is mounted on the driving end of the driving mechanism. The clamping assembly is disposed on the upper surface of the table and includes a constraint unit. The constraint unit includes a lower clamping frame, which is mounted on the upper surface of the table. A rotating hole is formed on the surface of the lower clamping frame, and the lower clamping frame is located on the inner wall of the rotating hole. The clamping assembly is movably connected to a first adjusting screw. The lower clamping frame is rotatably connected to a second adjusting screw located on the inner wall of the rotating hole. An upper clamping frame is slidably connected to the surface of the first adjusting screw. A connecting nut is fixedly connected to the lower surface of the upper clamping frame. The clamping assembly also includes a linkage unit. The linkage unit includes a first tooth groove, which is formed on the arc surface of the first adjusting screw. A second tooth groove is formed on the surface of the second adjusting screw. A transmission belt is installed on the inner wall of the first adjusting screw located on the first tooth groove. The transmission belt meshes with the inner wall of the second tooth groove.

[0007] Preferably, a reinforcing square sleeve is fixedly connected to the upper surface of the lower clamping frame. The reinforcing square sleeve can increase the structural strength between the lower clamping frame and the first adjusting screw and the second adjusting screw, thereby improving the firmness of the connection.

[0008] Preferably, an operating knob is fixedly connected to the upper surface of the first adjusting screw, and a limit baffle is installed on the surface of the first adjusting screw. The limit baffle is sleeved with the surface of the second adjusting screw. Through the cooperation of the first adjusting screw, the second adjusting screw and the connecting nut, the position of the upper clamping frame can be adjusted, so that the clamping assembly can clamp steel bars of different specifications.

[0009] Preferably, there are two reinforcing sleeves, which are arranged symmetrically about the lower clamping frame. One reinforcing sleeve is fitted onto the surface of the first adjusting screw, and the other reinforcing sleeve is fitted onto the surface of the second adjusting screw. The lower clamping frame can assist the upper clamping frame in clamping the reinforcing bar and ensure the stability of the reinforcing bar during the testing process.

[0010] Preferably, there are two connecting nuts, which are symmetrically arranged about the upper clamping frame. The connecting nuts are threaded to the surface of the first adjusting screw and the second adjusting screw. The position of the upper clamping frame can be restricted by the connecting nuts, thereby ensuring the stability of the upper clamping frame.

[0011] Preferably, the limiting baffle abuts against the surface of the transmission belt, and there are two limiting baffles arranged symmetrically about the transmission belt. The limiting baffles can protect the transmission belt and ensure its stability during operation.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up a clamping assembly, during testing, the rebar to be tested is placed in the clamping assembly and clamped and fixed using the clamping assembly. Upon completion of the operation, the drive mechanism is switched on, energizing it and pushing the push plate. The push plate moves to the surface of the rebar being tested and continuously compresses it. During this compression process, the generated data is displayed on the drive mechanism's screen for the testing personnel to view. When clamping the rebar, it is inserted into the clamping area formed by the upper and lower clamping frames. The operating knob is rotated, and the operating knob engages with the first operating knob. The drive belt engages with the second tooth groove, causing the second adjusting screw to rotate. The first and second adjusting screws rotate synchronously and engage with the connecting nuts on both sides of the upper clamping frame. The connecting nuts on both sides pull the upper clamping frame, causing it to move. When the upper clamping frame reaches the surface of the rebar, it can cooperate with the lower clamping frame to clamp the rebar. By setting the clamping components, the device can detect rebars of different specifications, thereby reducing the problem of the fixed size of the clamping structure leading to a narrow range of applications and further improving the applicability and practicality of the device.

[0017] Specifically, a reinforcing square sleeve 515 is fixedly connected to the upper surface of the lower clamping frame 511.

[0018] In this embodiment, the structural strength between the lower clamping frame 511 and the first adjusting screw 512 and the second adjusting screw 513 can be increased by strengthening the square sleeve 515, thereby improving the firmness of the connection part.

[0019] Specifically, an operating knob 524 is fixedly connected to the upper surface of the first adjusting screw 512, and a limit baffle 525 is installed on the surface of the first adjusting screw 512. The limit baffle 525 is sleeved with the surface of the second adjusting screw 513.

[0020] In this embodiment, there are two reinforcing sleeves 515, which are arranged symmetrically about the lower clamping frame 511. The reinforcing sleeve 515 is sleeved on the surface of the first adjusting screw 512, and the other reinforcing sleeve 515 is sleeved on the surface of the second adjusting screw 513.
