Description

Technical Field

[0001] The utility model relates to the field of ultrasonic flaw detection equipment, in particular to a handheld ultrasonic flaw detection equipment used for detecting amusement facilities. Background Art

[0002] The large-scale amusement facilities in the amusement park are all made of steel materials welded together. The welds are also the weak points in the structure of the amusement facilities. In order to avoid hidden structural cracks that may cause structural fractures during the use of the amusement facilities and reduce safety hazards, flaw detection must be carried out at all times during the construction of the amusement facilities. The commonly used detection method is ultrasonic flaw detection, which can effectively detect cracks or defects inside metal materials or components.

[0003] Large amusement facilities are built in outdoor environments, and dust and gravel are often attached to the surface. When ultrasonic testing is used for inspection, the ultrasonic probe will be contaminated by dust when it rests against the surface of the steel structure of the amusement facility. In addition, a layer of dust between the ultrasonic probe and the steel structure of the amusement facility will also affect the accuracy of ultrasonic testing.

[0004] Therefore, in order to address the problem that dust and gravel exist on the surface of the steel components of the above-mentioned large-scale outdoor amusement facilities, and that direct use of ultrasonic probes for flaw detection can easily affect the accuracy of detection, an ultrasonic flaw detector with a synchronous cleaning structure can be designed. With the help of an external handle installed at the ultrasonic probe and equipped with a wind-powered cleaning structure, the surface of the steel components of the amusement facilities in the inspection area can be cleaned before flaw detection. Utility Model Content

[0005] In order to overcome the dust and gravel on the surface of steel components of large outdoor amusement facilities, direct use of ultrasonic probes for flaw detection can easily affect the accuracy of detection.

[0006] The technical solution of the utility model is: a handheld ultrasonic flaw detection device for amusement facility inspection, comprising an ultrasonic flaw detector, a signal line connected to a signal interface of the ultrasonic flaw detector, an ultrasonic probe fixedly installed at the end of the signal line, a fan built into a top housing of the ultrasonic flaw detector, a bracket and a buckle installed on the signal line; the buckle is a ring structure with an opening at the edge and is clamped on the signal line, the bracket is a hollow structure and is fixedly connected to the outer side wall of the buckle, an assembly connector for fixing the buckle to the signal line is provided between the buckle and the bottom of the ultrasonic probe, an air ring connected to the air outlet channel of the fan is provided on the outer side of the ultrasonic probe, a circle of 8-12 air holes is provided on the surface of the air ring, and the angle between the axis of the air holes and the axis of the ultrasonic probe is 30-60 degrees.

[0007] Preferably, the casing of the original ultrasonic flaw detector is improved and a built-in fan is provided. This ultrasonic flaw detector is an existing product with mature technology and is relatively common on the market. Specifically, the CTS-1002 digital ultrasonic flaw detector can be selected, and then the buckle is installed on the signal line, and the buckle is fixed to the ultrasonic probe through the assembly connector, so that the wind ring is on the periphery of the ultrasonic probe. The operator holds the body of the ultrasonic flaw detector in one hand and the ultrasonic probe close to the surface of the steel structure of the amusement facility in the other hand. The fan first outputs the air flow through the air holes on the wind ring, and blows the dust to the part to be inspected on the surface of the steel structure of the amusement facility. Then, the ultrasonic probe is placed against the cleaned surface of the steel structure, and the ultrasonic flaw detector is started to transmit ultrasonic waves to the steel structure with the ultrasonic probe for flaw detection.

[0008] Preferably, a cavity is provided at the upper end of the shell of the ultrasonic flaw detector, and the fan is installed in the cavity. A cover is snap-fitted to the upper opening of the cavity, and an air supply hose is fixedly connected between the cover and the bracket. The original shell of the ultrasonic flaw detector is improved and designed to increase the shell structure to leave enough space for the setting of the cavity. The fan runs in the cavity and transmits air flow to the outside through the air supply hose. The cover serves as a closed structure of the cavity, and the fan can be inspected and maintained after it is opened.

[0009] Preferably, a branch pipe is fixedly connected to one side of the lower end of the air ring, and a bearing is provided at the lower end of the branch pipe. The bearing is fixed to the upper end of the bracket by a threaded connection structure and connects the air ring, branch pipe, bracket and air supply hose. After the buckle is clamped to the signal line, the branch pipe is installed using the bearing and threaded connection structure. The branch pipe is rotated so that the screw head on the bearing enters the screw mouth on the bracket. During the rotation, the air ring does not rotate due to the setting of the bearing.

[0010] Preferably, an outward-extending inclined plate is integrally fixedly connected to the side wall of the opening of the buckle, and an arc-shaped chamfer is provided on the edge of the inclined plate. The two inclined plates form an eight-shaped structure. When the eight-shaped opening structure formed by the inclined plates is connected to the signal line, the signal line can be gradually pressed in along the eight-shaped opening, which is easier to install than the buckle structure without an inclined plate.

[0011] Preferably, a U-shaped handle is fixedly connected to the upper end of the bracket, the vertical part of the handle is parallel to the axis of the ultrasonic probe, and a non-slip rubber sleeve is provided on the outer wall of the handle. When the user uses ultrasonic flaw detection, the user holds the handle with his hand to operate the mobile ultrasonic probe. Compared with the original method of directly holding the ultrasonic probe, the holding space is larger and the operation is more flexible.

[0012] Preferably, the assembly connector includes a magnetic ring and a rubber magnetic strip; the magnetic ring is fixedly connected to the bottom end of the ultrasonic probe, and a rubber magnetic strip is embedded in the upper surface of the buckle. The rubber magnetic strip is magnetically attracted to the magnetic ring and fixes the buckle to the signal line at the lower end of the ultrasonic probe. After the buckle is clamped on the signal line, the buckle is moved along the signal line close to the ultrasonic probe until the upper surface of the buckle contacts the magnetic ring. Through the magnetic attraction between the magnetic ring and the rubber magnetic strip, the buckle will not move along the signal line or detach from the ultrasonic probe, keeping the wind ring on the outer periphery of the ultrasonic probe.

[0013] Preferably, the assembly connector includes a top ring piece, a pin hole and a connecting bolt; the top ring piece is fixedly connected to the bottom end of the ultrasonic probe, a pin hole is opened on the top ring piece, and a connecting bolt is fixedly connected to the upper end of the buckle near the opening, the connecting bolt is inserted into the corresponding pin hole and fixed by tightening with a nut. After the buckle is clamped on the signal line, the buckle is moved along the signal line close to the ultrasonic probe until the connecting bolt is inserted into the corresponding pin hole, and the upper surface of the buckle is tightly attached to the top ring piece, and a limit is formed by the connecting bolt and the top ring piece, and then the connecting bolt is tightened with a nut to prevent the connecting bolt from falling out of the pin hole. At this time, the buckle will not move along the signal line or detach from the ultrasonic probe, keeping the wind ring on the outer periphery of the ultrasonic probe.

[0014] Beneficial effects of the utility model:

[0015] 1. By installing a small fan in the original ultrasonic flaw detector casing and combining it with the wind ring structure installed at the ultrasonic probe, dust and gravel on the surface of the detection position can be blown away in advance when ultrasonic flaw detection is performed on the surface of the steel components of amusement facilities in an amusement park, avoiding contamination caused by contact with the ultrasonic probe. At the same time, there will be no problem of dust between the ultrasonic probe and the steel component affecting the accuracy of flaw detection.

[0016] 2. The assembly connector is used as a fixing structure for the buckle, ultrasonic probe and signal line, which is easy to install and disassemble and flexible to use;

[0017] 3. With the help of the U-shaped handle set on the bracket, it serves as a gripping structure for the operator during ultrasonic flaw detection. Compared with the original method of directly grasping the ultrasonic probe, it is not easy to contaminate the ultrasonic probe, and the gripping surface is larger and the operation is more flexible.

Then, the ultrasonic probe 3 is placed against the cleaned surface of the steel structure, and the ultrasonic flaw detector 1 is started, and the ultrasonic probe 3 transmits ultrasonic waves to the steel structure for flaw detection.

[0031] See also Figure 1-Figure 3 、 Figure 5-10The air blower 5 is installed in the air blower 5 by the air blower 5, and the air blower 5 is installed in the air blower 5 by the air blower 5. The branch pipe 14 allows the screw head on the bearing part to enter the screw mouth on the bracket 8. During the rotation process, the air ring 10 does not rotate due to the setting of the bearing part. The side wall of the opening of the buckle 9 is integrally fixedly connected with an outwardly extending inclined plate 13, and the edge of the inclined plate 13 is provided with an arc chamfer. The two inclined plates 13 form an eight-shaped structure.

After the buckle 9 is clamped on the signal line 2, the buckle 9 is moved along the signal line 2 close to the ultrasonic probe 3 until the upper surface of the buckle 9 contacts the magnetic ring 1101. The magnetic attraction between the magnetic ring 1101 and the rubber magnetic strip 1102 prevents the buckle 9 from moving along the signal line 2 or detaching from the ultrasonic probe 3, thereby keeping the air ring 10 on the outer periphery of the ultrasonic probe 3.

A connecting bolt 1105 is fixedly connected to the position near the opening of the upper end of the buckle 9. The connecting bolt 1105 is inserted into the corresponding pin hole 1104 and is tightened and fixed by a nut. After the buckle 9 is clamped on the signal line 2, the buckle 9 is moved along the signal line 2. 9 moves closer to the ultrasonic probe 3 until the connecting bolt 1105 is inserted into the corresponding pin hole 1104, and the upper surface of the retaining ring 9 is in close contact with the top ring piece 1103, forming a limit by the connecting bolt 1105 and the top ring piece 1103, and then tightening the connecting bolt 1105 with the nut to prevent the connecting bolt 1105 from falling out of the pin hole 1104. At this time, the retaining ring 9 will not move along the signal line 2 or disengage from the ultrasonic probe 3, keeping the wind ring 10 on the outer periphery of the ultrasonic probe 3.

At the same time, there will be no problem of dust between the ultrasonic probe 3 and the steel components affecting the accuracy of the flaw detection, so as to solve the problem that dust and gravel exist on the surface of the steel components of large outdoor amusement facilities, and the direct use of the ultrasonic probe 3 for flaw detection is likely to affect the accuracy of the detection.
