Description

Technical Field

[0001] The utility model belongs to the technical field of concrete steel bar detection, and particularly relates to a concrete steel bar detection device. Background Technique

[0002] Since concrete has the characteristics of high compressive strength and low tensile strength, steel bars have the characteristics of high tensile strength and low compressive strength, and the linear expansion coefficients of concrete and steel bars are similar. Therefore, when the two are used together, good compressive and tensile abilities can be obtained. In order to ensure the quality of the combination of concrete and steel bars, relevant detections of concrete steel bars need to be carried out through detection devices.

[0003] The Chinese patent with the publication number of CN220289607U discloses a steel bar detection device after the formation of reinforced concrete, including a device main body and a disassembly mechanism arranged on the outer wall of the device main body. By setting a card slot, when it is necessary to detect concrete steel bars through the detection device, in order to improve the detection flexibility of concrete steel bars and prevent the tediousness of manually holding a detector to detect each part of the concrete, first place the concrete main body on the surface of the device, insert the steel bar detector body into the outer wall of the connecting rod, rotate the bolt, and through the action of the nut, drive the bolt to slide into the card slot, playing the role of clamping and installing the detector and the threaded slider, and turn on the driving motor. By rotating the threaded rod, drive the threaded slider to slide along the inner wall of the fixed slot, and drive the steel bar detector body to reciprocally detect along one side of the concrete, realizing the control operation of improving the detection flexibility of concrete steel bars during the detection of concrete steel bars.

[0004] However, in the actual use process, since reinforced concrete test blocks have various size models, the thicknesses corresponding to different reinforced concrete test blocks may be different. Although the above device can realize the disassembly, installation and automatic detection functions of the detector through the reciprocating assembly and the clamping assembly, due to the different thicknesses of the reinforced concrete test blocks, the distances between the surfaces of the test blocks and the detection ends of the detector are different, resulting in the above solution being unable to effectively detect test blocks with different thicknesses. Content of the Utility Model

[0005] The utility model aims to provide a concrete steel bar detection device to solve the problem that the existing detection device mentioned above cannot detect concrete steel bar test blocks with different thicknesses.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A concrete steel bar detection device includes

[0007] a detection table, with connecting frames installed at both ends respectively, and a reciprocating mechanism installed between the two connecting frames;

[0008] Lifting mechanism, including a cylinder, a lifting plate and a lifting rod. The cylinder is installed on the reciprocating mechanism. The lifting plate is fixed to the movable end of the cylinder. The lifting rod is fixed to the bottom of the lifting plate. The bottom edge of the lifting rod is located below the bottom edge of the reciprocating mechanism;

[0009] Concrete steel bar detector, installed at the bottom of the lifting rod and above the surface of the testing table;

[0010] Clamping mechanism, installed on the testing table and used for clamping the test block.

[0011] Principle and effect of this technical solution:

[0012] 1. The cylinder drives the lifting plate to rise and fall, so that the lifting rod can drive the concrete steel bar detector to rise and fall. After test blocks of different thicknesses are placed on the testing table, the height of the concrete steel bar detector can be adjusted to make the concrete steel bar detector fit the surface of test blocks of different thicknesses, so that the device can accurately detect test blocks of different thicknesses and improve the applicable range of the device.

[0013] 2. Through the setting of the reciprocating mechanism, after the test block is clamped by the clamping mechanism and placed on the testing table, it can spontaneously drive the concrete steel bar detector to perform relevant tests on the test block, thus saving manpower.

[0014] The present utility model is further configured as: The reciprocating mechanism includes a sliding plate, a sliding block, a reciprocating screw rod and a reciprocating motor. The sliding plate is fixed to the top inside the two connecting frames. The sliding block is slidably sleeved on the sliding plate. A chute is opened on the sliding plate. The reciprocating screw rod is rotatably installed in the chute. The sliding block is in threaded cooperation with the reciprocating screw rod. The reciprocating motor is fixed to the outer wall of the connecting frame. The driving end of the reciprocating motor is connected to the reciprocating screw rod. The cylinder is fixed to the top of the sliding block.

[0015] Principle and effect of this technical solution: The reciprocating motor drives the rotation of the reciprocating screw rod, so that the sliding block can reciprocate on the sliding plate, so that the lifting mechanism can drive the concrete steel bar detector to move back and forth, avoiding the process of manually holding the detector and saving manpower.

[0016] The present utility model is further configured as: A guiding ear with a "U" - shaped cross - section is fixed to the side wall of the sliding block. The lifting rod is slidably inserted inside the guiding ear.

[0017] Principle and effect of this technical solution: The setting of the guiding ear can limit and guide the lifting rod, so that the lifting rod can stably drive the concrete steel bar detector to move up and down under the drive of the cylinder, ensuring the stability of the height adjustment of the concrete steel bar detector. At the same time, it can share the horizontal stress received by the lifting rod when the concrete steel bar detector is detecting, so that the lifting rod can maintain a vertical state.

[0018] The utility model is further configured as follows: the lifting mechanism also includes a spring-loaded assembly, the spring-loaded assembly includes a connecting plate, a spring-loaded rod, a limit block, a protective plate and a spring, the connecting plate is fixed to the bottom of the lifting rod, the spring-loaded rod and the connecting plate are slidably inserted, the limit block is fixed to the top of the spring-loaded rod, the bottom of the limit block is located above the top of the connecting plate, the protective plate is fixed on the spring-loaded rod and is located below the connecting plate, the spring is sleeved on the spring-loaded rod and is located between the connecting plate and the protective plate, the concrete steel bar detector is detachably connected to the spring-loaded rod, and the top of the concrete steel bar detector abuts against the protective plate.

[0019] The principle and effect of the technical solution are as follows: the connecting plate is directly connected to the lifting rod, and the spring-pressure rod and the connecting plate are slidably inserted into each other, so that after the cylinder drives the concrete rebar detector to press against the surface of the test block, the concrete rebar detector can move the spring-pressure rod upward relative to the connecting plate through the pressing protective shell and the pressing spring-pressure rod, thereby avoiding the situation where the concrete rebar detector is damaged due to excessive downward pressure of the cylinder, and at this time the cylinder can continue to drive the connecting plate to move downward, thereby further compressing the spring, so that the rebound force of the spring acts on the concrete rebar detector, so that the concrete rebar detector is fully pressed against the surface of the test block, that is, the setting of the spring-pressure assembly makes the concrete rebar detector not easily crushed and can be fully pressed against the surface of the test block, and the setting of the protective plate can distribute the force area of ​​the concrete rebar detector, thereby avoiding local stress.

[0020] The utility model is further configured as follows: a connecting tube is installed on the side wall of the concrete steel bar detector, a connecting bolt is threadedly inserted on the outer side of the connecting tube, the elastic pressure rod is slidably matched with the connecting tube, and a limiting hole is opened on the side wall of the elastic pressure rod, and the end of the connecting bolt is adapted to the limiting hole.

[0021] The principle and effect of this technical solution: by rotating the connecting bolt, the position of the connecting bolt relative to the limiting hole can be controlled, thereby controlling the position of the spring-pressure rod relative to the connecting tube, so that the concrete steel bar detector can be disassembled from the lifting mechanism for subsequent maintenance and replacement, and the disassembly and assembly steps are simple and convenient.

[0022] The utility model is further configured as follows: the clamping mechanism includes a driving assembly and two clamping plates symmetrical about the detection platform, the driving assembly includes a driving motor, a driving screw and a driving block, the driving motor is fixed to the bottom of the detection platform, the driving screw is rotatably installed on the bottom of the detection platform, and the driving screw is connected to the rotating end of the driving motor, the driving block is threadedly mounted on the driving screw, and the driving block is abutted against the bottom of the detection platform, a driving groove is opened on the detection platform, a rotating shaft is fixed to the bottom of the clamping plate, the rotating shaft is slidably fitted in the driving groove, the bottom of the rotating shaft extends to the bottom of the bottom of the detection platform, and is hinged with a transmission plate, and the other end of the transmission plate is hinged to the driving block.

[0023] Principle and effect of this technical solution: By driving the driving screw to rotate with a driving motor, the driving block can slide at the bottom of the detection table. Through the sliding of the driving block, the crank-slider mechanism composed of the driving block, transmission plate and rotating shaft moves, that is, the sliding of the driving block can drive the rotating shaft to move along the driving groove, so that the clamping plate approaches or moves away from the test block. Through the setting of two symmetric clamping plates, this clamping mechanism has the function of centering clamping and the function of adapting to test blocks of different widths.

[0024] The present utility model is further configured as: the driving screw is a bidirectional screw, there are two driving blocks which are symmetric about the driving screw, and two rotating shafts are symmetrically installed at the bottom of one clamping plate.

[0025] Principle and effect of this technical solution: By setting the driving screw as a bidirectional screw, and there are two sets of driving blocks, rotating shafts and transmission plates respectively, the acting points of the driving force received by the clamping plate are more uniform, so that the clamping plate can better drive and clamp the test block.
