Description

Technical Field

[0001] The utility model relates to the technical field of crack detection, in particular to a crack detection device. Background Art

[0002] After a certain period of use, cracks will appear on the wall. At this time, the inspection personnel need to use the transducer to inspect the cracked wall to obtain the data of the wall cracks. When inspecting the cracks on the exterior wall, the inspection personnel need to hold the transducer against the cracked wall for inspection, but the cracks in the wall sometimes appear in the high parts of the exterior wall. At this time, it is difficult for the inspection personnel to detect the cracks in the high wall, which affects the smooth progress of the inspection work.

[0003] The patent with application number 202321945504.1 discloses a crack detection device for building exterior walls, which relates to the field of wall detection technology, including a mounting block and a transducer, and one side of the mounting block is fixedly connected to one end of the transducer. In the utility model, by arranging a telescopic rod under the mounting block, when it is necessary to detect cracks at a higher height, the device can be placed on the edge of the wall, and then the No. 2 synchronous wheel can be driven to rotate by turning the handle, and the No. 1 synchronous wheel connected to it will also rotate accordingly. At this time, the No. 1 gear fixed to the No. 1 synchronous wheel will also rotate, and its rotating No. 1 gear will drive the telescopic rod meshing with it to move upward. At this time, the action wheel on the mounting block will move on the wall until it moves to the crack position.

[0004] However, this technical solution utilizes a lifting structure to push the mounting block to move on the side wall of the wall. Since the lifting structure is rotatably connected to the bottom of the mounting block, pressure is applied to the bottom of the mounting block during the lifting process, causing the mounting block to be affected by the extrusion force during the movement, and the top of the mounting block is easily separated from the wall. Since the mounting block cannot be completely attached to the wall, there is a deviation in the data detected by the detection device during the movement. Summary of the invention

[0005] The purpose of the utility model is to provide a crack detection device in view of the shortcomings of the prior art. The device can realize the function of the lifting frame always being in contact with the wall during the mobile detection process by cooperating with the lifting frame structure slidably arranged in the support frame, thereby solving the problem of the lifting frame being separated from the wall during the movement.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crack detection device, comprising a support frame attached to a wall surface and a lifting frame slidably arranged in the support frame, power mechanisms for driving the lifting frame are installed at both ends of the support frame, and a base is embedded and fixed at the bottom end of the support frame, one side of the lifting frame is embedded with a plurality of detection rods in a rectangular array, and the other side of the lifting frame is fixed with a plurality of display lights corresponding to the detection rods, wherein a plurality of telescopic slots are opened on the lifting frame, the detection rods are elastically inserted in the telescopic slots, and the outer wall of the detection rod and the inner wall of the telescopic slot are installed with staggered electrode plates.

[0007] Preferably, both ends of the support frame are provided with slide grooves, a mounting plate is fixed to the bottom end of one of the slide grooves, and a receiving groove is provided through the mounting plate.

[0008] Furthermore, the power mechanism includes a lead screw rotatably arranged in the slide groove and a motor embedded in the receiving groove, and the shaft of the motor is fixedly connected to the lead screw.

[0009] Furthermore, the top ends of the two lead screws pass through the support frame and are fixedly sleeved with gears, and a toothed belt is meshed between the two gears.

[0010] Furthermore, sliding parts that are fitted and inserted in the sliding grooves are fixed at both ends of the lifting frame, and the lead screw is threadedly inserted in the sliding parts.

[0011] Furthermore, batteries are embedded in both ends of the lifting frame, and the batteries are electrically connected to the electrode plates and the display lights respectively.

[0012] Furthermore, a spring is embedded in the telescopic slot, and two ends of the spring are respectively in contact with the inner wall of the telescopic slot and the detection rod.

[0013] Furthermore, a card slot is provided at the bottom end of the support frame, and a card connection portion which fits and is inserted into the card slot is fixed at the top end of the base.

[0014] The beneficial effects of the utility model are:

[0015] (1) The utility model is provided with a support frame, and the support frame is fitted with the wall surface through a base fixedly embedded in one side of the bottom end thereof. During the detection process, the motor in the accommodating groove drives the lead screw to rotate, and the two lead screws rotate synchronously through the gears and the toothed belt.

[0016] (2) The utility model provides a telescopic slot in the lifting frame, in which a spring and a detection rod are embedded. When the lifting frame moves to the crack, the spring in the telescopic slot pushes the detection rod into the crack. During the movement of the detection rod, the electrode plate on the detection rod contacts the electrode plate on the inner wall of the telescopic slot, thereby generating a signal of a touch switch, which lights up the display light corresponding to the detection rod. The display light makes it easy to observe the state of the wall crack, thereby improving the convenience of detecting and observing the wall crack. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Slide grooves 6 are provided at both ends of the support frame 1, and a mounting plate 14 is fixed at the bottom end of one of the slide grooves 6, and a receiving groove 9 is separated by the mounting plate 14. The power mechanism includes a lead screw 13 rotatably set in the slide groove 6 and a motor 12 embedded in the receiving groove 9.

A toothed belt 4 is meshed between the two gears 5. Sliding parts 16 that are fitted and inserted in the slide grooves 6 are fixed at both ends of the lifting frame 3. The lead screw 13 is threadedly inserted in the sliding part 16. During the detection process, the lead screw 13 is driven to rotate by the motor 12 in the receiving groove 9.

[0028] like Figure 4 and Figure 5 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that: batteries 15 are embedded at both ends of the lifting frame 3, and the batteries 15 are electrically connected to the electrode plates 17 and the display lights 8 respectively. A spring 18 is embedded in the telescopic slot 19, and the two ends of the spring 18 are respectively in contact with the inner wall of the telescopic slot 19 and the detection rod 2.
