Description

Technical Field

[0001] This utility model relates to the technical field of steel plate testing, and in particular to a testing instrument for steel plates in dump truck bodies. Background Technology

[0002] The dump truck body is an important component of the dump truck, responsible for loading and unloading goods. The steel plates of the body need to be inspected and maintained regularly to check the strength, hardness, degree of corrosion, and presence of cracks, ensuring the stable operation of the dump truck.

[0003] Existing steel plate testing equipment, such as the ultrasonic phased array testing device for steel plates disclosed in utility model patent application number 202421570755.0, mainly includes a U-shaped base. A transmission component is installed on the inner wall of the U-shaped base, and the steel plate to be tested is placed on the top wall of the transmission component. A testing component is installed on the outer wall of the U-shaped base. In use, the steel plate to be tested is placed on the transmission belt via the feeding table. The motor drives the transmission roller and the transmission belt to transport the steel plate to the middle of the U-shaped base. After the testing probe is placed into the receiving frame and the protective pad and magnetic suction frame door are closed, the testing probe is controlled by an external ultrasonic testing instrument to start detecting its movement trajectory on the steel plate. This allows the position of the testing probe to be adjusted through the cooperation of various components during ultrasonic testing of the steel plate, thereby reaching various positions on the steel plate for ultrasonic testing.

[0004] However, most existing testing instruments are designed to test unassembled steel plates, making it difficult to test steel plates assembled into carriages. Furthermore, they are difficult to clean when contaminated or corroded, which can easily affect the ultrasonic detection of cracks. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a dump truck body steel plate inspection device that can not only clean and remove rust from steel plates before ultrasonic testing, thus improving the accuracy of ultrasonic testing, but also inspect assembled truck bodies, thus improving the flexibility of the device.

[0006] This utility model discloses a steel plate inspection device for dump truck bodies, comprising an inspection mechanism; it also includes a control mechanism, two sets of moving mechanisms, a cleaning mechanism, and a dust collection mechanism. The control mechanism is installed on the inspection mechanism to facilitate the operation of the device by the operator. Both sets of moving mechanisms are installed on the inspection mechanism to inspect the levelness of the steel plate. The cleaning mechanism is installed on the inspection mechanism to polish away contamination and rust. The dust collection mechanism is installed on the control mechanism to collect waste. The operator moves the inspection mechanism through the control mechanism, and the two sets of moving mechanisms simultaneously move the device and inspect the flatness of the steel plate. The cleaning mechanism cleans the rust and contamination on the steel plate, and the waste is collected by the dust collection mechanism, facilitating the inspection mechanism to use ultrasonic waves to detect whether there are cracks in the steel plate.

[0007] Preferably, the testing mechanism includes a support frame, an ultrasonic detector, two sets of ear plates, and a rotating shaft. The support frame is placed on the working surface and has two sets of sliding grooves and six sets of limiting grooves. The top of the ultrasonic detector is connected to the top of the support frame, and the bottom of the two sets of ear plates is connected to the top of the support frame. The rotating shaft is rotatably mounted on the two sets of ear plates. The control mechanism is connected to the rotating shaft, which allows for easy adjustment of the operator's pushing angle, causing the support frame to turn. The ultrasonic detector emits ultrasonic waves to detect cracks on the surface of the steel plate.

[0008] Preferably, the control mechanism includes a connecting rod, a sliding rod, a fixing bolt, a controller, and a handle. The connecting rod is mounted on a rotating shaft and has multiple sets of positioning holes. The sliding rod is slidably connected to the connecting rod. The fixing bolt is rotatably mounted on the sliding rod. The bottom end of the controller is connected to the top end of the sliding rod. The handle is mounted on the controller. The operator adjusts the insertion depth of the connecting rod according to their height and detection position, and then screws the fixing bolt into the positioning hole of the connecting rod to fix it. The operator holds the handle and pushes the sliding rod and the connecting rod. The controller displays the detection effect of the ultrasonic detector and the moving mechanism.

[0009] Preferably, the moving mechanism includes a sensor, two sets of telescopic rods, two sets of springs, a connecting plate, six sets of connecting shafts, three sets of rollers, and six sets of sealing heads. The sensor is mounted on a support frame. The top ends of the two sets of telescopic rods are connected to the bottom ends of the sensor. The two sets of springs are respectively fitted onto the two sets of telescopic rods. The top end of the connecting plate is connected to the bottom ends of the two sets of telescopic rods. All three sets of connecting shafts are rotatably mounted on the connecting plate. Each set of connecting shafts is equipped with two sets of rollers located on both sides of the connecting plate. Each set of connecting shafts has a sealing head installed on its two end faces. The rollers roll on the steel plate. When there is a protrusion on the surface of the steel plate, the two sets of telescopic rods are pushed upward. The sensor detects the retracted length of the two sets of telescopic rods to determine whether the surface of the steel plate is flat. When the steel plate is flat, the two sets of springs rebound and push the connecting plate and rollers back to their original positions. The lifting height of the rollers is limited by the sealing heads.

[0010] Preferably, the roller is also embedded with a magnetic block; by embedding the magnetic block, the roller can move easily on the steel plates on the side and top of the carriage, which improves the flexibility of the device and gives it a larger detection range.

[0011] Preferably, the cleaning mechanism includes a motor, a first drive shaft, a second transmission shaft, a wire brush, two sets of sprockets, and a chain. The bottom end of the motor is connected to the top end of the support frame, the input end of the first drive shaft is connected to the output end of the motor, the second transmission shaft is rotatably mounted on the support frame, the wire brush is mounted on the second transmission shaft, the two sets of sprockets are respectively mounted on the first drive shaft and the second transmission shaft, and the chain drive is installed between the two sets of sprockets. When the motor is started, the motor drives the sprocket connected to it to rotate through the first drive shaft. The sprocket drives the other set of sprockets and the second transmission shaft to rotate through the chain. The second transmission shaft drives the wire brush to rotate, and the wire brush removes rust and cleans the surface of the steel plate.

[0012] Preferably, the dust collection mechanism includes an impurity pump, an extraction pipe, a suction hopper, a conveying pipe, and a dust collection bag. The bottom end of the impurity pump is connected to the top end of the support frame. The extraction pipe is installed on the impurity pump. The suction hopper is installed on the support frame and communicates with the inside of the extraction pipe. The conveying pipe is installed on the impurity pump. The dust collection bag is installed on the connecting rod and communicates with the inside of the conveying pipe. When the impurity pump is started, it extracts the waste debris swept by the wire brush through the extraction pipe and the suction hopper. Then, the waste debris is conveyed to the dust collection bag for collection through the conveying pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the staff pushes the detection mechanism to move through the control mechanism, and the two sets of moving mechanisms drive the device to move while detecting the flatness of the steel plate. The cleaning mechanism cleans the rust and pollution on the steel plate, and the waste debris is collected by the dust collection mechanism, which makes it convenient for the detection mechanism to use ultrasound to detect whether there are cracks in the steel plate.
