Description

Technical Field

[0001] The utility model relates to the field of pipe testing equipment, in particular to a non-destructive testing device for the inner wall of a pipe. Background Art

[0002] Pipes are materials used to make pipe fittings. The quality of pipes directly determines the quality of pipe fittings. Pipe testing products include: PPR pipes, PVC pipes, UPVC pipes, copper pipes, steel pipes, fiber pipes, composite pipes, galvanized pipes, hoses, reducers, water supply pipes, etc.

[0003] When using pipes, they need to be inspected to see if there are any cracks on the inner wall. Ultrasonic detection devices are generally used to detect damage to the inner wall of the pipe. Existing devices do not provide any protection for the display screen and operating panel of the device control unit when not in use. If a flying object hits the device while it is in place, it will directly damage it, resulting in low safety and hindering its use. Furthermore, existing devices have poor protection for the ultrasonic detection device. If a worker slips, this part will directly fall to the ground, causing damage to the device itself. The device's detection structure itself is low in safety. Summary of the Invention

[0004] The purpose of the utility model is to provide a non-destructive testing device for the inner wall of a pipe to address the corresponding deficiencies of the prior art. The non-destructive testing device for the inner wall of a pipe has high safety and long service life.

[0006] The protective connecting plate is a rectangular connecting plate, and the four corners of the protective connecting plate are respectively connected to a protective support rod. The protective support rods at the two rear corners of the protective connecting plate are connected and fixed to the rear end of the control box body, and the bottom end of each protective support rod is fixedly connected to a rubber base.

[0007] The outer surfaces of the ultrasonic emitting device and the ultrasonic receiving device are both fixedly connected to a fixed protective cover by fixing screws, and the bottom end of the fixed protective cover is connected and fixed to the upper end surface of the protective connecting plate.

[0008] The two sides of the lower end of the control box body are fixedly connected to the first ears, the first ears are slidably matched with the first rotating shaft, connecting blocks are respectively provided at both ends of the first rotating shaft, the upper end of the connecting block is slidably matched with the first rotating shaft, and the lower end of the connecting block is slidably matched with the second rotating shaft, second ears are respectively provided at both ends of the second rotating shaft, and the bottom end of the second ear is fixedly connected to the protective cover.

[0009] The front bottom end of the protective cover is connected and fixed to the bottom ends of multiple first connecting bases, the top end of each first connecting base is respectively connected and fixed to one side of the shock-absorbing spring, the other side of each shock-absorbing spring is respectively connected and fixed to the bottom end of the second connecting base, the top end of each second connecting seat is connected and fixed to a fixing plate, and the top end of the fixing plate is connected to a sponge pad.

[0010] A plurality of suction cup bases are arranged at the rear end of the protective cover.

[0011] A box door is provided on the left side of the rear end of the control box body, and the box door is fixed to the control box body by screws. A plurality of ventilation holes are provided on the right side of the rear end of the control box body, and the inner side walls of the ventilation holes are fixed to the dustproof net.

[0012] A second holding handle is respectively provided on both sides of the control box body, and a soft rubber sleeve is provided on the outer surface of the second holding handle.

[0013] A first holding handle is provided at the middle portion of the upper end of the protection connecting plate.

[0014] Control buttons are arranged on the control panel.

[0015] The advantages of the utility model are: 1. By providing a protective cover, a shock-absorbing spring and a fixing plate, when the device is in use, the protective cover can be rotated to the back of the control box body so that the suction cup base on the back of the protective cover adsorbs the movable door. When the control box body is not in use, in order to strengthen the protection of the control box body, the protective cover is rotated so that the protective cover blocks the top of the control box body to prevent flying objects from hitting the control box body and causing damage to it. When a flying object hits the control box body, it will first hit the protective cover above the control box body. When it hits the protective cover, the shock-absorbing spring inside the protective cover will contract to reduce the vibration of the control box body caused by the hit. The function of the sponge layer is to reduce the pressure of the fixing plate on the control box body and strengthen the protection of the control box body, thereby achieving the purpose of better protection of the control part of the device when the device is placed.

[0016] 2. By setting a fixed protective cover, a protective connecting plate and a protective support column, when the device is in use, the function of the fixed protective cover is to strengthen the stability of the connection between the ultrasonic wave transmitting device and the ultrasonic receiving device and the protective connecting plate, so that the protective connecting plate surrounds the ultrasonic wave transmitting device and the ultrasonic receiving device to avoid collision with other objects, thereby strengthening the protection of both. When the staff's hands slip and the ultrasonic wave transmitting device and the ultrasonic receiving device fall, the protective support column will first contact the ground to prevent the ultrasonic wave transmitting device and the ultrasonic receiving device from directly hitting the ground and causing damage. The rubber base connected to the bottom end of the protective support column has greater elasticity, which reduces the vibration of the ultrasonic wave transmitting device and the ultrasonic receiving device, strengthens the protection of both, and thus achieves the purpose of better protection of the device for the detection part.
