Description

Technical Field

[0001] This utility model relates to the field of building crack detection technology, specifically a crack detection device for engineering buildings. Background Technology

[0002] Wall cracks are cracks that occur in the wall parts of a building structure. Depending on the material itself, they can be divided into concrete wall cracks, brick masonry wall cracks, new partition wall cracks, and cracks caused by walls of different materials. In order to ensure the quality of the building, cracks need to be detected and the building needs to be evaluated.

[0003] A crack detector is a device used for detecting cracks in buildings. It includes a probe and a main unit. The probe can display the cracks it captures on the main unit, thereby detecting the width of the crack. However, existing crack detectors require one hand to hold the probe and the other hand to hold the main unit during operation. When using them, the probe must be held at the crack position while observing the main unit, resulting in poor holding stability. Therefore, a new engineering building crack detection device is proposed to optimize the existing technology. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4In this embodiment of the utility model, an engineering building crack detection device includes a vertical rod 1, a threaded rod 2 threadedly connected to the bottom end of the vertical rod 1, a hexagonal rotating head 3 fixedly connected to the threaded rod 2, pads 4 fixedly connected to the bottom end of the threaded rod 2 and the top end of the vertical rod 1, a sliding sleeve 5 adapted to it being slidably sleeved on the vertical rod 1, a horizontal groove 6 provided on the upper outer side of the sliding sleeve 5, a vertical groove 7 connected to the horizontal groove 6, a rotating seat 8 fixedly connected to both ends of the vertical groove 7, a fixed sleeve 9 dampedly rotatably connected to the inner side of the rotating seat 8, a probe 11 adapted to it being provided inside the fixed sleeve 9, and a U-shaped buckle 12 adapted to it being fastened to the outer side of both the vertical groove 7 and the horizontal groove 6, the vertical groove 7... A connecting piece 13 is provided between the vertical groove 7 and the horizontal groove 6. The connecting piece 13 has a long strip protrusion 14 corresponding to both the vertical groove 7 and the horizontal groove 6. The long strip protrusions on both sides are vertically arranged to form a horizontal and vertical double guide. The long strip protrusions 14 are inserted into the vertical groove 7 and the horizontal groove 6 respectively and are slidably connected. Damping pads 15 are provided on both sides of the connecting piece 13 and the inner side of the U-shaped buckle 12. A threaded post 16 is fixedly connected to one of the U-shaped buckles 12. The threaded post 16 passes through the connecting piece 13, the damping pad 15 and the other U-shaped buckle 12 and is threaded to a wing nut 17. The lower outer side of the sliding sleeve 5 is connected to a placement groove 18. The placement groove 18 is equipped with a crack measuring instrument main unit 19 that is compatible with it. The crack measuring instrument main unit 19 has its own power supply and is electrically connected to the probe 11 through a connecting wire harness.

[0023] The probe 11 is connected to the vertical rod 1 via the fixed sleeve 9, rotating seat 8, vertical groove 7 and horizontal groove 6. The crack measuring instrument main unit 19 is connected to the vertical rod 1 via the placement groove 18. The vertical rod 1, through the condition of the threaded rod 2, drives the two pads 4 to form an upper and lower clamping, thereby supporting it inside the building. Thus, the device can be used without having to hold the probe 11 and the crack measuring instrument main unit 19 by hand.

[0024] The probe 11 rotates in a damped manner within the rotating seat 8 via the fixed sleeve 9, thereby adjusting the measurement angle. At the same time, the vertical groove 7 and the horizontal groove 6 form a sliding connection through the U-shaped buckle 12, the connecting piece 13, and the elongated protrusion 14, allowing for adjustment of the lateral and longitudinal positions. In conjunction with the threaded column 16, the damping washer 15, and the wing nut 17, the sliding between the connecting piece 13 and the vertical groove 7, and between the horizontal groove 6 and the connecting piece 13, forms a damped sliding effect, thus facilitating control of the probe 11's alignment with the crack.

[0025] The first threaded handle 30 is threadedly connected to the fixed sleeve 9. One end of the first threaded handle 30 is inserted into the fixed sleeve 9 and abuts against the outer wall of the probe 11.

[0026] The top of the placement slot 18 is provided with a wire harness avoidance notch 20, and the bottom of the placement slot 18 is threadedly connected with a second threaded handle 21. The threaded end of the second threaded handle 21 is inserted into the placement slot 18 and abuts against the housing of the crack measuring instrument main unit 19.

[0027] The probe 11 is assembled in the fixed sleeve 9 via the first threaded handle 30, and the crack measuring instrument main unit 19 is assembled in the placement groove 18 via the second threaded handle 21, so that the crack measuring instrument can be conveniently combined with this device.

[0028] The inner side of the sliding sleeve 5 is provided with an extrusion head 22 corresponding to the groove on the vertical rod 1. A guide post 23 is symmetrically fixedly connected to the extrusion head 22. The guide post 23 slides through the side wall of the sliding sleeve 5. A third threaded handle 24 is threadedly connected to the sliding sleeve 5. The third threaded handle 24 abuts against the extrusion head 22.

[0029] The sliding sleeve 5 can slide along the vertical rod 1. By rotating the third threaded handle 24, the extrusion head 22 is driven to press against the groove of the vertical rod 1, thereby forming an extrusion and fixing effect. This makes it convenient to adjust the measurement height and to measure cracks at different heights on the wall.

[0030] The outer side of the sliding sleeve 5 is rotatably fitted with a matching rotating sleeve 25, and the placement groove 18 is connected to the rotating sleeve 25 via a connecting rod.

[0031] The two sides of the rotating sleeve 25 are symmetrically fixedly connected with guide sleeves 26. A U-shaped rod 27 is slidably connected through the guide sleeves 26. A fourth threaded handle 28 is threadedly connected through the middle of the U-shaped rod 27. The end of the fourth threaded handle 28 is rotatably connected to the rotating sleeve 25. The end of the U-shaped rod 27 is fixedly connected to a stop plate 29. A transverse groove 6 is fixedly connected to the stop plate 29 and extends to one side.

[0032] The rotating sleeve 25 rotates on the outside of the sliding sleeve 5 to facilitate the control of the orientation of the probe 11 to the wall. Then, the rotation of the fourth threaded handle 28 drives the movement of the U-shaped rod 27, which in turn causes the abutment plate 29 to press against the wall to form a compression constraint, thereby bringing the probe 11 closer to the wall and facilitating measurement.

[0033] The working principle of this utility model is as follows: In use, the vertical rod 1 is erected inside the building, close to the cracked wall. The threaded rod 2 is rotated using the hexagonal rotating head 3, causing the pads 4 to move apart and rest against the building roof and ground respectively, forming a support and fixation. At this time, the sliding sleeve 5 slides along the vertical rod 1. Further rotation of the third threaded handle 24, under the action of the guide post 23, drives the extrusion head 22 to press against the vertical rod 1, thus fixing the sliding sleeve 5. Then, rotating the rotating sleeve 25 aligns the abutment plate 29 with the wall. Rotating the fourth threaded handle 28 drives the U-shaped rod 27 to slide along the guide assembly 26, thereby causing the abutment plate 29 to press against the wall. At this point, the probe 11 can be inserted into the fixing sleeve 9 and connected via the first threaded... The handle 30 is locked and fixed. The crack measuring instrument main unit 19 is placed in the placement groove 18 and locked and fixed by the second threaded handle 21. The angle of the probe 11 can be adjusted by rotating the fixing sleeve 9 in the rotating seat 8. At the same time, the vertical groove 7 can slide along the vertical strip protrusion 14 on the connecting piece 13 to adjust the height. The connecting piece 13 can slide along the horizontal groove 6 through the horizontal strip protrusion 14 to adjust the horizontal position, so as to make it easy to adjust the probe 11 to correspond with the crack position and move along the crack. At this time, it can be released and suspended. At this time, the crack measuring instrument main unit 19 can be observed and measured without continuous hand holding. The mechanical support makes it more stable.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
