Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of steel bar detection, in particular to a steel bar strength detector for water conservancy engineering quality detection. BACKGROUND

[0002] Steel bar refers to steel material for reinforced concrete and prestressed reinforced concrete, and its cross section is circular or square with rounded corners. Steel bars are often used in water conservancy projects. To ensure construction quality, steel bars are usually sampled and subjected to bending detection before use.

[0003] In the prior art, a patent document with publication number CN213875288U discloses a building steel bar quality bearing degree detector, which includes a base and a crossbeam. The crossbeam is supported by a support column above the base, and the support column is distributed on the lower sides of the crossbeam. The middle surface of the base is provided with a through opening, and the surfaces of the base on both sides of the through opening are provided with support plates. Steel bar grooves are formed in the support plates on both sides, and the steel bar grooves are equidistantly distributed between them. Electro-hydraulic push rods are fixed to the front and rear sides of the middle part of the crossbeam, and the electro-hydraulic push rods penetrate through the lower part of the crossbeam.

[0004] During use, it is found that the above-mentioned device can only detect the bending degree of steel bars with a fixed length, and has certain limitations in use. UTILITY MODEL CONTENTS

[0005] To solve the above technical problems, the utility model provides a steel bar strength detector for water conservancy engineering quality detection with reduced use limitations.

[0006] The steel bar strength detector for water conservancy engineering quality detection of the utility model includes a workbench and a controller. The front end of the workbench is provided with the controller. The workbench is also provided with an adjusting assembly, a support seat assembly, and a bending test assembly. The top end of the workbench is provided with the adjusting assembly, which is provided with two sets of support seat assemblies. The adjusting assembly is used for mirror image movement of the two sets of support seat assemblies. The top end of the workbench is provided with the bending test assembly. The adjusting assembly and the bending test assembly are electrically connected with the controller. During use, the distance between the two sets of support seat assemblies is adjusted by operating the adjusting assembly through the controller according to the length of the steel bar to be detected. After adjustment, the steel bar is placed on the two sets of support seat assemblies. Then, the bending strength of the steel bar is detected by operating the bending test assembly. The flexibility is improved, and the use limitations are reduced.

[0007] Preferably, the adjustment assembly includes a guide rod, a lead screw, a motor, a support plate, a motor base, and movable seats. A groove is provided at the top of the worktable, in which the guide rod is fixedly mounted and a set of lead screws is rotatably mounted. A support plate is provided at the right end of the worktable. The motor is mounted on the top of the support plate via a motor base, and the motor output end is connected to one end of the lead screw. Two sets of movable seats are threadedly connected to the lead screw and slidably connected to the guide rod. Each set of movable seats has a set of support seat assemblies at its top. In use, the motor is started by the controller according to the length of the reinforcing bar being detected, thereby allowing the lead screw to adjust the distance between the two sets of movable seats in cooperation with the two sets of guide rods, further adjusting the distance between the two sets of support seat assemblies, thus improving flexibility.

[0008] Preferably, the support assembly includes side plates, a rotating shaft, a support base, a positioning groove, and a counterweight. Two sets of side plates are mounted on the top of the movable base, and a rotating shaft rotatably connects the two sets of side plates. A support base is mounted on the rotating shaft, and a positioning groove is located on the top of the support base. A counterweight is located at the bottom of the support base, and the top of the support base is higher than the top of the side plates. In use, the positioning grooves on the two sets of support bases respectively position and support the reinforcing bars. When the reinforcing bars are bent under the action of the bending test assembly, the two sets of support bases adapt their angles with the cooperation of the corresponding rotating shafts, ensuring that the reinforcing bars and positioning grooves always maintain surface contact, reducing wear on the support bases caused by the reinforcing bars.

[0009] Preferably, the bending test assembly includes columns, a top plate, an electric hydraulic cylinder, a pressure head, and a lifting plate. Multiple sets of columns are installed at the top of the workbench, with the tops of each set connected to the bottom of the top plate. An electric hydraulic cylinder is installed at the top of the top plate, and a lifting plate is installed at the bottom moving end of the electric hydraulic cylinder. A pressure head is installed at the bottom of the lifting plate. The electric hydraulic cylinder is electrically connected to a controller. According to the test requirements, the controller adjusts the elongation pressure of the electric hydraulic cylinder, thereby causing the lifting plate to drive the pressure head to detect the bending of the reinforcing bar, improving testing efficiency.

[0010] Preferably, it also includes a guide rod, which is provided at the top of the lifting plate and is slidably connected to the top plate; the lifting plate drives the pressure head to move up and down stably under the guidance of the guide rod, thereby improving stability.

[0011] Preferably, the worktable also includes adjustable feet, with a set of adjustable feet provided at each of the four corners of the bottom of the worktable; the four sets of adjustable feet work together to provide stable support for the worktable and improve stability.

[0012] Preferably, it also includes a limiting plate, and the top of the movable seat is provided with a limiting plate; after the bending test of the steel bar is completed, the steel bar is removed, and the support seat will swing left and right during the recovery process with the cooperation of the rotating shaft and the counterweight. The limiting plate limits the swinging counterweight, and further makes the support seat quickly stop.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, according to the length of the reinforcing bar being tested, the spacing between the two sets of support base components is adjusted by operating the adjustment component through the controller. After the adjustment is completed, the reinforcing bar is placed on the two sets of support base components, and then the bending test component is operated to test the bending strength of the reinforcing bar, which improves flexibility and reduces the limitations of use.
