DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, an ultrasonic crack depth detection device includes a waist belt 1, a support plate 2, a support rod 3, a support plate 4, a detector 5 and a fixing mechanism 6.

[0019] like Figure 1 As shown, the waist belt 1 is used to bind and fix on the waist position of the inspector, and the support plate 2 is vertically arranged on the front side of the waist belt 1 and located at the abdomen position of the inspector.

[0020] like Figure 3 As shown, the lower end of the support rod 3 is rotatably set on the lower side walls of both sides of the support plate 2, and the middle position of the support rod 3 is rotatably connected with a pull rod 31, and a slider 32 is rotatably set on the pull rod 31, and a slide groove 33 for the slider 32 to slide vertically is set on the support plate 2.

[0021] like Figure 3 As shown, both sides of the support plate 2 are horizontally slidably connected with locking rods 34 that pass through the lower end of the sliding groove 33, and the outer wall of the sliding block 32 is provided with a locking hole 35 for the locking rod 34 to be inserted.

[0022] like Figure 3As shown, the support plate 4 is rotatably connected between a pair of support rods 3 and is turned over to lie flat against the support plate 2 so as to achieve storage of the support plate 4 .

[0023] like Figure 3 , Figure 4 , Figure 5 As shown, a rotating shaft 41 penetrating the support rod 3 is horizontally arranged on both sides of the support plate 4, and a ratchet gear 42 is arranged at the outer end of the rotating shaft 41. A cover 43 covering the ratchet gear 42 is arranged on the support rod 3, and a ratchet ring 44 matching the ratchet gear 42 is horizontally slidably connected in the cover 43. A spring 45 is arranged between the ratchet ring 44 and the cover 43, and a handle 46 penetrating the cover 43 is arranged on the ratchet ring 44.

[0024] like Figure 3 , Figure 4 As shown, the detector 5 is arranged on the supporting plate 4, and a groove 47 for the detector 5 to be embedded is arranged on the supporting plate 4, and a pair of probes 51 are connected to the detector 5 through wires. A telescopic extension rod 7 is inserted on both sides of the support plate 2, and a clamping claw 71 for clamping the probe 51 is arranged on the extension rod 7.

[0025] like Figure 3 , Figure 4 As shown, the fixing mechanism 6 is used to fix the detector 5 on the supporting plate 4, and the fixing mechanism 6 includes a pair of clamping blocks 61 and a bidirectional screw 62. The pair of clamping blocks 61 are horizontally slidably connected to the bottom wall of the groove 47, and the bidirectional screw 62 is rotatably connected in the supporting plate 4 and threadedly connected to the pair of clamping blocks 61. The inner side wall of the clamping block 61 is provided with a clamping block 63, and both sides of the detector 5 are provided with a clamping groove 64 for the clamping block 63 to be embedded.

[0026] When it is necessary to inspect the cracks in the building, the waist belt 1 is tied and fixed to the waist of the inspector, and the support plate 2 is located at the front side, at the abdomen of the inspector. Then the support rod 3 is controlled to flip downward, and the support rod 3 drives the pull rod 31 to rotate synchronously, and the pull rod 31 drives the slider 32 to slide downward. When the slider 32 slides to the bottom position of the slide groove 33, the lock rod 34 is controlled to plug into the lock hole 35 on the slider 32 to fix the slider 32, thereby fixing the support rod 3.

[0027] Then the supporting plate 4 is controlled to flip. When the supporting plate 4 flips, the supporting plate 4 drives the rotating shaft 41 to rotate synchronously, and the rotating shaft 41 drives the ratchet gear 42 to rotate. At this time, the ratchet gear 42 presses the ratchet ring 44 to move outward, and then under the elastic force of the spring 45, the ratchet ring 44 retreats and engages with the ratchet gear 42, realizing the unidirectional rotation limit of the supporting plate 4, thereby realizing the fixation of the supporting plate 4 after being compressed.

[0028] Then, the detector 5 is embedded in the groove 47 on the supporting plate 4, and the bidirectional screw 62 is rotated to drive a pair of clamps 61 to approach each other, so that the clamps 61 clamp and fix the two sides of the detector 5, and the blocks 63 on the clamps 61 are embedded in the slots 64 on both sides of the detector 5 to fix the detector 5.

[0029] Then, the probe 51 is connected to the detector 5 by a wire to detect the crack position. When the position to be detected is relatively high, the extension rods 7 on both sides of the support plate 2 can be taken out, and the extension rods 7 can be controlled to extend, and then the probe 51 can be fixed on the clamping claw 71. At this time, the probe 51 can be controlled on the ground for detection without using tools such as ladders, so that the detection personnel can detect high cracks on the ground, which improves the convenience of use.

[0030] Therefore, by setting a waist belt 1 that can be fixed at the waist position, and cooperating with a support rod 3 and a support plate 4 that can be freely flipped, the detector 5 is fixed at the abdomen of the tester, and the angle of the detector 5 can be freely adjusted, so that one person can carry the detector 5 for convenient observation of values ​​and the handheld probe 51 for testing at the same time, without the need for two people to cooperate, making the testing process more convenient, reducing labor costs, and improving testing efficiency.

[0031] After the detection is completed, the bidirectional screw 62 is controlled to rotate so that the clamping block 61 is separated from the detector 5, and then the detector 5 can be removed. Then, the handle 46 on the cover 43 is pulled outward to make the handle 46 drive the ratchet ring 44 to separate from the ratchet gear 42, and then the carrier plate can be controlled to flip in the opposite direction and flip to a position on the same horizontal plane as the support tube to achieve storage of the carrier plate.

[0032] Then pull the locking rod 34 to slide outward to disengage the locking hole 35 on the slider 32, and then control the support rod 3 and the supporting plate 4 to flip in the opposite direction, so that the support rod 3, the supporting plate 4 and the pull rod 31 all fit the surface of the supporting plate 2 to achieve the storage of the entire device, and then remove the waist belt 1 to achieve convenient storage and storage of the entire device, reduce the occupied space, and make it convenient to carry.

[0033] like Figure 3 , Figure 4 As shown, a sun visor 8 located in front of the detector 5 is tiltedly arranged on the supporting plate 4, and the sun visor 8 is rotatably connected to the supporting plate 4, and a torsion spring 81 is arranged at the rotating position. A support rod 82 is rotatably connected to the supporting plate 4, and positioning rods 83 are arranged on both sides of the sun visor 8, and a positioning clip 84 is arranged on the support rod 82 for the positioning rod 83 to be embedded.

[0034] When there is sufficient sunlight in the working environment, the sun visor 8 is controlled to flip upward, and then the support rod 82 is controlled to flip synchronously, so that the positioning rod 83 on the sun visor 8 is embedded in the positioning clip 84 on the support rod 82, so as to support the entire sun visor 8, so that the sun visor 8 is used to block the light of the detector 5, avoiding direct sunlight and unclear readings, making the detection process more convenient.

[0035] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
