[0007] Furthermore, an elastically retractable auxiliary locking block is provided on the clamping hoop near the hinge.

[0008] Furthermore, one end of the clamping arm is connected to the housing via a tension spring configured inside the housing, which can extend and retract vertically.

[0009] Furthermore, the ultrasonic probe is an array of 4, 6, or 8 probes.

[0010] Furthermore, it also includes an ultrasonic testing instrument that is connected to the ultrasonic probe via a wired or wireless connection.

[0011] Furthermore, the inner arc-shaped surface of the clamping hoop is provided with several evenly spaced circular buffer pads.

[0012] Furthermore, the clamping part is provided with several evenly spaced circular buffer pads on the side facing the clamping cavity.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1 As shown, this utility model embodiment provides a boom fork lug fracture detection device, including: Casing 1, Two clamping hoops 2 are arc-shaped and symmetrically arranged facing each other. One end of each clamping hoop 2 is hinged to the housing 1, and the other end is connected to each other in a snap-fit ​​manner to form a hollow cylindrical clamping cavity for clamping the fork lug of the rod to be tested. A clamping arm 3, one end of which is connected to the housing 1, and the other end extends upward and bends to form a clamping part 11 located above the clamping cavity; The ultrasonic probe 4 is respectively disposed on the arc-shaped inner side of the clamping clamp 2 and on the side of the clamping part 11 facing the clamping cavity.

[0023] In this embodiment, the housing 1 adopts a rectangular or square structure with a hollow interior. It is made of high-strength aluminum alloy, which has good mechanical properties and corrosion resistance, while reducing the weight of the entire device and making it easy to carry, install, and operate.

[0024] The clamping clamps 2 are arc-shaped, and two clamping clamps 2 are symmetrically arranged facing each other to form a hollow cylindrical clamping cavity for clamping the straight rod part of the boom fork lug to be tested. The clamping clamps 2 can be made of highly elastic stainless steel, such as 304 stainless steel, which has good elasticity and corrosion resistance and can withstand large clamping forces.

[0025] One end of the clamping hoop 2 is hinged to the housing 1 via a stainless steel hinge shaft 10, and the other end is connected by a snap-fit ​​mechanism, such as a pair of matching hooks 5 and slots 6, to achieve quick clamping and disassembly. The hinge shaft 10 is vertically fixed inside the hollow cavity of the housing 1, and one end of the clamping hoop 2 is rotatably hinged via a bearing passing through the hinge shaft 10.

[0026] In addition, an elastically retractable auxiliary clamping block 8 is provided on the clamping clamp 2 near the hinge. It is made of polyurethane elastomer material, which has good elasticity and wear resistance. It can adjust the clamping space during the clamping process and can also provide additional clamping force to ensure the stability of the clamping.

[0027] Specifically, the auxiliary card block 8 can be connected to the corresponding slot inside the clamping hoop 2 via a telescopic spring.

[0028] One end of the clamping arm 3 is connected to the housing 1, and the other end extends upward and bends to form a clamping part 11 located above the clamping cavity, which is used to apply additional clamping force to the U-shaped groove of the boom fork from above. One end of the clamping arm 3 is connected to the housing 1 by a tension spring configured inside the housing 1. The spring is made of high-strength carbon steel and can provide stable elastic force to ensure the vertical extension and retraction function of the clamping arm 3.

[0029] Specifically, the clamping arm 3 is made of high-strength aluminum alloy, which has high strength and good fatigue resistance.

[0030] In addition, the contact surface between the locking part 11 and the fork lug can be a U-shaped arc surface or a flat surface.

[0031] The clamping clamp 2 has several evenly spaced circular buffer pads 9 on its arc-shaped inner surface. The clamping part 11 also has several evenly spaced circular buffer pads 9 on its side facing the clamping cavity. Specifically, the buffer pads 9 are made of highly elastic silicone, possessing good flexibility and wear resistance, reducing damage to the fork lug surface during clamping, providing uniform clamping force, and ensuring the stability and reliability of the testing process.

[0032] The ultrasonic probe 4 is respectively set on the inner arc-shaped side of the clamping clamp 2 and the side of the clamping part 11 facing the clamping cavity, and is used to transmit and receive ultrasonic signals to realize non-destructive testing of the boom fork lug.

[0033] Specifically, the ultrasonic probe 4 uses an array of 4, 6, or 8 probes, with the appropriate number selected according to the testing requirements. The probes 4 are evenly distributed on the clamping clamp 2 and the locking part 11 to ensure full coverage of the testing area.

[0034] The ultrasonic testing instrument is used to control the transmission and reception of the ultrasonic probe 4, process the detection signal, and display the detection results on the screen in real time. The testing instrument connects to the ultrasonic probe 4 via wired or wireless means. Wired connections use shielded cables, while wireless connections use Wi-Fi or Bluetooth technology to ensure the flexibility and stability of signal transmission.

[0035] Probe 4 is connected to the ultrasonic detector via a shielded cable. The cable features a multi-layer shielding design to ensure the stability of signal transmission and its anti-interference capability.

[0036] In use, the boom fork lug to be tested is placed into the clamping cavity formed by the clamping clamp 2. The clamping clamp 2 is then connected via a snap-fit ​​mechanism, ensuring it fits tightly against the straight rod portion of the fork lug. The vertical position of the clamping arm 3 is then adjusted using a tension spring, causing the clamping part 11 to clamp the U-shaped groove of the fork lug from above. After installation and clamping, the ultrasonic testing instrument is activated. The probe 4 emits and receives ultrasonic signals along the layout of the clamping clamp 2 and the clamping part 11. The instrument processes the signals in real time and displays the test results to the testing operator.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
