Description

Technical Field

[0001] The invention relates to the technical field of engineering quality monitoring equipment, and in particular to a concrete structure engineering construction quality monitoring device. Background Art

[0002] According to GB50204-2015 "Concrete Structure Engineering Construction Quality Acceptance Code", the quality acceptance of concrete structure sub-division engineering construction, in addition to the visual quality should be qualified, the structural entity inspection must also be qualified. Structural entity inspection. It is mainly carried out on representative parts involving the safety of concrete structures, including three major items: ① concrete strength, ② steel bar protective layer thickness, ③ structural position and size deviation. For finished and semi-finished concrete structures, they are generally tested by concrete detectors, which are mainly composed of a body and a probe. The inspector holds the probe in hand and touches the concrete surface to obtain concrete data in the form of ultrasound. However, in actual use, for higher and vertical concrete structures, the height limits the convenience of probe detection, resulting in the need for inspectors to climb with the help of ladders to contact the high concrete surface. Summary of the invention

[0003] In view of the defects in the above-mentioned background technology that the probe of the line-stage concrete quality monitoring device needs to be handheld for detection and cannot directly monitor the concrete structure at a higher position, a technical solution content of a concrete structure engineering construction quality monitoring device is provided.

[0004] It includes a concrete detector, a monitoring probe traction climbing mechanism is arranged at the probe end of the concrete detector, and two monitoring probe clamping ends are arranged on the front side surface of the monitoring probe traction climbing mechanism;

[0005] The concrete detector includes a detector body and 2-3 cable connectors fixed on the front end face of the detector body. A transmission harness of at least 10m in length is plugged into the port of the cable connector, and a monitoring probe is connected to the end of the transmission harness away from the cable connector. Since the monitoring probe traction climbing mechanism has the ability to drive the probe to climb along the wall, and the user can basically stand still, a transmission harness of at least 10m in length is required to adapt to the operation of the monitoring probe traction climbing mechanism, and on the other hand, it can reduce the distance the user follows and walks. Moreover, 2-3 cable connectors are set on the concrete detector in order to be able to connect 2-3 probes at the same time, so that the 2-3 monitoring probe traction climbing mechanisms can drive 2-3 probes for detection at the same time, thereby speeding up the detection speed of the concrete structure.

[0006] The monitoring probe traction climbing mechanism includes a support plate, a silicone frame fixed to a circle around the edge of the rear surface of the support plate, and a wind tube fixed to the middle area inside the support plate, a servo motor is fixed in the inner cavity of the wind tube, and the output shaft of the servo motor is connected to the turbofan blade through a coupling, and a driving motor is installed at the four corner positions of the support plate, and the output shaft of the driving motor is connected to the plastic roller through a coupling; wherein, due to the different roughness of the surface of the concrete structure, the wind force generated by the turbofan blades and the servo motor is insufficient to support any action of the climbing mechanism, therefore, in the replacement scheme, the servo motor can be replaced by a high-frequency motor to provide a faster rotation speed for the turbofan, thereby providing a greater downward force for the climbing mechanism, and a metal filter can be set at the air inlet port of the wind tube to prevent the wind tube from inhaling debris on the surface of the concrete structure, causing damage to the turbofan blades.

[0007] Specifically, the operation of the servo motor and the drive motor is controlled by the detector body. The output shaft of the drive motor drives the plastic roller to roll synchronously, and the servo motor drives the turbofan blades to rotate at high speed, thereby extracting the air between the support plate and the silicone frame to form a negative pressure. The generation of negative pressure allows the support plate to be adsorbed on the concrete surface, and the plastic roller drives the clamping end of the monitoring probe and the clamped monitoring probe to move, so as to achieve the purpose of detecting the concrete by moving on the concrete surface.

[0008] The detector body controls the operation of the servo motor and the drive motor. The output shaft of the drive motor drives the plastic roller to roll synchronously, and the servo motor drives the turbofan blades to rotate at high speed, thereby extracting the air between the support plate and the silicone frame to form a negative pressure. The generation of negative pressure allows the support plate to be adsorbed on the concrete surface, and the plastic roller drives the clamping end of the monitoring probe and the clamped monitoring probe to move. If the surface of the concrete structure is relatively rough and has large potholes, the silicone frame is designed to be in the central control state, and the silicone frame can be inflated. Therefore, a servo air pump can be installed on the upper surface of the support plate. By expanding the hollow silicone frame, it has the ability to deform freely, so as to adapt to the concrete structure with a relatively rough surface and large potholes, allowing the monitoring probe to pull the climbing mechanism to climb the wall stably.

[0009] The monitoring probe clamping end includes a servo electric cylinder fixedly connected to the front side surface of the support plate, a fixed seat fixed to the top end surface of the servo electric cylinder, and a movable seat arranged above the fixed seat, the telescopic end of the servo electric cylinder is connected to a telescopic shaft penetrating the fixed seat, and the top end of the telescopic shaft is fixedly connected to the bottom surface of the movable seat;

[0010] Specifically, after turning on the detector body, straighten the transmission harness, and place the monitoring probe between the clamp arms. Use the control button on the detector body to control the telescopic end of the servo electric cylinder to drive the telescopic shaft to move downward. In the process of pulling the movable seat downward, the pulling arm and the bent rod are driven to expand outward. On the contrary, when the telescopic shaft moves upward, the pulling arms approach each other, and the bent rods also approach each other, thereby forcing the clamp arms to approach each other to clamp the monitoring probe. Among them, since the probe needs to contact the surface of the concrete structure or maintain a millimeter-level spacing, the clamp arm can change the clamping position of the probe before detection. With the help of a vernier caliper, measure the spacing between the end of the probe and the surface of the concrete structure after the monitoring probe is pulled and attached to the surface of the concrete structure by the climbing mechanism, so as to obtain the applicable detection spacing according to the different concrete structures and expand its applicable scenarios.

[0011] Among them, a guide column is fixed on both the front and rear sides of the bottom surface of the movable seat, the bottom end of the guide column is fixedly connected to the top surface of the fixed seat, a connecting plate passes through the outer ring of the guide column, and a bent rod is hinged at both ends of the left and right ends of the connecting plate.

[0016] In the above-mentioned technical solution of the device for monitoring the construction quality of concrete structure engineering, preferably: the front and rear end surfaces of the air duct are both in an open state, and the rotation direction of the turbofan blades forces the air on the rear side of the support plate to flow to the front side, thereby forming a negative pressure on the rear surface of the support plate and the inner area of ​​the silicone frame and adsorbing on the concrete surface.

[0017] In the above-mentioned technical solution of the device for monitoring the construction quality of concrete structure engineering, preferably: the front end face of the silicone frame is adhered to the rear surface of the support plate along the edge shape of the support plate by an adhesive, and there is a gap of 1-3 mm between the rear end face of the silicone frame and the concrete surface for air to enter from the gap.
