DETAILED DESCRIPTION

[0022] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0023] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 4 As shown, an embodiment of the utility model provides a crack detection device for a new concrete structure, comprising a detection body 1, a joint 102, a connecting line 7 and a planar transducer 8, wherein both ends of the connecting line 7 are fixedly connected to the planar transducer 8 and the joint 102 respectively, and the joint 102 is fixedly connected to the upper end of the detection body 1, and the detection body 1 is fixedly installed in the base plate 2 through a limit plate 3, and both ends of the lower surface of the base plate 2 are detachably installed with brackets 4 through fasteners 402, and two wire-laying plates 6 for placing the connecting line 7 are movably arranged in the middle of the lower surface of the base plate 2, and a placement box 5 for placing the planar transducer 8 is fixedly installed at one end of the lower surface of the base plate 2.

[0025] Furthermore, anti-collision pads 101 are fixedly installed at the four corners of the detection body 1, and a support plate 401 is fixedly connected to the bottom of the bracket 4.

[0026] In the present application, both sides of the four anti-collision pads 101 are higher than the two sides of the detection body 1, which can reduce the damage to the detection body 1 during a collision and reduce the risk of equipment damage due to a collision. The support plate 401 and the bracket 4 are used to support the detection body 1. When detecting concrete cracks, there is no need to manually hold the detection body 1 for operation, which makes it more convenient and easy to use and reduces the risk of the detection body 1 slipping from the hand.

[0027] Furthermore, two limiting rings 501 are fixedly connected to the inner wall of the bottom of the placement box 5 , and the two planar transducers 8 are respectively placed in the two limiting rings 501 .

[0028] In the present application, by setting a placement box 5 for placing the planar transducer 8 on the base plate 2, the planar transducer 8 can be conveniently stored and more convenient to use. The planar transducer 8 is limited by the limiting ring 501 to improve the stability of the planar transducer 8.

[0029] Furthermore, a bending portion is upwardly provided at one end of the base plate 2, and the bending portion is tightly pressed against one end of the detection body 1, and a screw sleeve 203 is fixedly installed inside the other end of the base plate 2, and a screw rod 202 is connected to the inner thread of the screw sleeve 203, and a knob 201 is fixedly connected to one end of the screw rod 202, and the other end of the screw rod 202 is rotatably installed in the middle of one side of the limit plate 3, and guide rods 204 are fixedly connected to one side of the limit plate 3 and at both ends of the screw rod 202, and the two guide rods 204 both slide through one side of the base plate 2, and the limit plate 3 is tightly pressed against the end of the detection body 1 away from the bending portion.

[0030] In the present application, the base plate 2 is U-shaped, with one end abutting against the side of the detection body 1, and the bent part abutting against the upper surface of the detection body 1. The limit plate 3 is "7"-shaped and abuts against the other side of the detection body 1. During assembly, the detection body 1 is placed on the upper surface of the base plate 2 so that one end of the detection body 1 fits with one end of the base plate 2, and then the screw 202 is driven to rotate by turning the knob 201. Through the threaded cooperation between the screw 202 and the screw sleeve 203, the limit plate 3 moves in the direction close to the detection body 1 until the detection body 1 is pressed tightly to achieve the fixation of the detection body 1. By setting two guide rods 204, the stability of the limit plate 3 can be improved. Through the above technical solution, the detection body 1 can be easily fixed and disassembled, which is convenient for use and carrying.

[0031] Furthermore, a fixed block 601 is fixedly connected to the middle of the lower surface of the base plate 2, and a first telescopic rod 602, a second telescopic rod 603 and a spring 604 are fixedly connected to both sides of the fixed block 601. The ends of the first telescopic rod 602, the second telescopic rod 603 and the spring 604 on both sides away from the fixed block 601 are respectively fixedly connected to the two wire-releasing plates 6, and the two springs 604 are respectively mounted on the two second telescopic rods 603, and the connecting wire 7 is wound around the two wire-releasing plates 6.

[0032] In the present application, the connecting wire 7 is manually rolled up into a ring shape, and then the two wire-paying plates 6 are pushed in a direction toward each other, so that the two first telescopic rods 602, the second telescopic rod 603 and the spring 604 are contracted, and then the rolled-up connecting wire 7 is placed on the wire-paying plate 6. When the wire-paying plate 6 is loosened, the spring 604 rebounds under the action of its own elastic force, driving the first telescopic rod 602 and the second telescopic rod 603 to extend, thereby causing the two wire-paying plates 6 to move in opposite directions, tightening the connecting wire 7 and fixing the connecting wire 7, making it easier to store the connecting wire 7 for next use.

[0033] The working principle of this utility model:

[0034] During assembly, the detection body 1 is placed on the upper surface of the base plate 2 so that one end of the detection body 1 fits with one end of the base plate 2, and then the screw 202 is driven to rotate by turning the knob 201. Through the threaded cooperation between the screw 202 and the screw sleeve 203, the limit plate 3 moves in the direction close to the detection body 1 until the detection body 1 is pressed tightly to fix the detection body 1. The connecting line 7 is manually rolled up into a ring shape, and then the two wire-releasing plates 6 are pushed in the direction of approaching each other to shrink the two first telescopic rods 602, the second telescopic rod 603 and the spring 604. Then the rolled-up connecting line 7 is sleeved on the wire-releasing plate 6. When the wire-releasing plate 6 is loosened, the spring 604 is 04 rebounds under the action of its own elastic force, driving the first telescopic rod 602 and the second telescopic rod 603 to extend, so that the two wire-laying plates 6 move in the opposite direction, tighten the connecting wire 7, and fix the connecting wire 7. The two planar transducers 8 are respectively placed in the two limit circles 501 to fix the planar transducer 8. When in use, the connecting wire 7 is removed from the wire-laying plate 6, and the planar transducer 8 is taken out of the placement box 5. The two ends of the connecting wire 7 are connected to the connector 102 and the planar transducer 8 respectively, and one end of the planar transducer 8 is coated with coupling agent and placed at the point to be tested. The detection parameters are set through the detection body 1. After the detection is completed, the detection data is recorded.

[0035] In summary: this crack detection device for a new concrete structure supports the detection body 1 by setting a support plate 401 and a bracket 4. When detecting concrete cracks, there is no need to manually hold the detection body 1 for operation, which is more convenient and easy to use, and also reduces the risk of the detection body 1 slipping from the hand. By setting a placement box 5 for placing the planar transducer 8 on the bottom plate 2, the planar transducer 8 can be conveniently stored, which is more convenient when used. The detection body 1 is limited by the limiting plate 3 and the bottom plate 2, which can facilitate the installation and disassembly of the detection body 1, and is convenient to use and carry. The connecting line 7 is fixed by setting a wire release plate 6, which can be convenient for storage and next use.
