Description

Technical Field

[0001] This utility model relates to the field of building inspection technology, specifically to a mobile rebar inspection device. Background Technology

[0002] In the field of construction engineering, ensuring the correct placement of reinforcing steel bars within walls is crucial for the structural safety of buildings. With the development of the construction industry, the requirements for building quality are becoming increasingly stringent, necessitating precise detection of parameters such as the location, diameter, spacing, and protective layer thickness of reinforcing steel bars within walls. Traditional detection methods may require damaging the wall structure to obtain information about the reinforcing steel, which is clearly uneconomical and can damage the building structure. For example, in the renovation of some older buildings, using destructive testing methods may affect the overall stability of the building, and repairing damaged sections would increase costs. To meet the demand for non-destructive testing, mobile wall-mounted reinforcing steel detection devices have emerged. These devices can quickly and accurately obtain relevant information about the reinforcing steel without damaging the wall, thereby effectively assessing the quality of the building structure.

[0003] In the quality inspection of building construction projects, the accuracy requirements for detecting reinforcing steel bars within walls are becoming increasingly stringent. In the past, relying solely on handheld rebar detectors was problematic, as operator hand tremors and fatigue made it difficult to ensure the detector remained in a stable position. For example, when measuring parameters requiring high precision, such as rebar spacing and protective layer thickness, even minute displacements could lead to errors. Utility Model Content

[0004] In order to solve the technical problem that it is difficult to ensure that the detector is always in a stable detection position due to factors such as operator hand tremors and fatigue, this utility model provides a mobile rebar detection device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile rebar detection device, comprising: a support rod, the upper end of which is connected to a slider, the slider being slidably connected within a horizontal slide rail, the slider being connected to a vertical slide rail, an instrument clamp being slidably connected within the vertical slide rail, the instrument clamp being able to clamp the rebar detector, the detection surface of the rebar detector contacting the wall surface, and corresponding displacement mechanisms connected to both the horizontal and vertical slide rails, wherein one displacement mechanism can drive the slider to slide within the horizontal slide rail, and the other displacement mechanism can drive the instrument clamp to slide within the vertical slide rail, and a pedal is connected to the lower end of the support rod.

[0006] Preferably, the support rod includes a fixed cylinder, the lower end of which is connected to the pedal, and a threaded rod is slidably connected inside the fixed cylinder. The threaded rod has a groove that slides with a boss inside the fixed cylinder. A threaded sleeve is rotatably connected to the upper end of the fixed cylinder, and the threaded sleeve is threadedly connected to the threaded rod.

[0007] Preferably, the instrument fixture includes a second slider, which is slidably connected to a vertical slide rail. A slide rod is slidably connected inside the second slider, with its two ends connected to a limiting piece and a clamping piece, respectively. A spring is sleeved on the slide rod between the limiting piece and the second slider. The slide rod, limiting piece, clamping piece, and spring are provided in two sets and arranged in opposite directions. The two sets of slide rods are arranged parallel to each other in the vertical direction.

[0008] Preferably, the displacement mechanism includes a motor, two motors are respectively connected to one end of the horizontal slide rail and one end of the vertical slide rail, the motors are connected to lead screws, the two lead screws are respectively rotatably connected inside the horizontal slide rail and the vertical slide rail, and the two lead screws are respectively threadedly connected to slider one and slider two.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] In use, the detector is clamped in the instrument fixture and brought into contact with the wall. The operator then uses a foot pedal to fix the support rod. Two displacement mechanisms drive the clamped detector to move horizontally or vertically to detect whether the rebar is straight and the spacing. This provides a brand-new type of mobile rebar detection device that avoids manual handling. Furthermore, the instrument fixture allows the instrument to be adjusted in both horizontal and vertical directions to cooperate with the testing work of the instrument, thereby ensuring the stability of the instrument. Compared with manually holding the detector, the clamping effect is more stable, thus ensuring the measurement effect.

[0011] The detection height is adjusted by rotating the threaded sleeve to raise and lower the threaded rod, thus adapting to detection at different heights. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0019] The present invention will now be described in detail with reference to the accompanying drawings. Example

[0020] The following is in conjunction with the appendix Figure 1-4 This embodiment describes a mobile rebar detection device, comprising: a support rod 1, the upper end of which is connected to a slider 2, the slider 2 being slidably connected within a horizontal slide rail 3, the slider 2 being connected to a vertical slide rail 4, and an instrument clamp 5 being slidably connected within the vertical slide rail 4, the instrument clamp 5 clamping the rebar detector, the detection surface of the rebar detector contacting the wall surface, and corresponding displacement mechanisms 6 connected to both the horizontal slide rail 3 and the vertical slide rail 4, one displacement mechanism 6 driving the slider 2 to slide within the horizontal slide rail 3, and the other displacement mechanism 6 driving the instrument clamp 5 to slide within the vertical slide rail 4; and a pedal 7 connected to the lower end of the support rod 1.

[0021] In use, the detector is clamped in the instrument fixture 5 and brought into contact with the wall. The operator steps on the pedal 7 to fix the support rod 1. A set of displacement mechanisms 6 drives the slider 2 to slide in the horizontal slide rail 3, causing the vertical slide rail 4 to move horizontally with the detector. Another set of displacement mechanisms 6 drives the instrument fixture 5 to slide in the vertical slide rail 4, causing the detector to move vertically. This detects whether the steel bars are straight and the spacing. It solves the technical problem that it is difficult to ensure that the detector is always in a stable detection position due to factors such as operator hand tremors and fatigue.

[0022] The support rod 1 includes a fixed cylinder 11. The lower end of the fixed cylinder 11 is connected to the pedal 7. A threaded rod 12 is slidably connected inside the fixed cylinder 11. A groove 13 is provided on the threaded rod 12 to cooperate with the boss inside the fixed cylinder 11. A threaded sleeve 14 is rotatably connected to the upper end of the fixed cylinder 11. The threaded sleeve 14 is threadedly connected to the threaded rod 12. The upper end of the threaded rod 12 is connected to a slider 2.

[0023] When adjusting the detection height, rotate the threaded sleeve 14. The threaded sleeve 14 drives the threaded rod 12 to slide along the fixed cylinder 11 through the thread. The slide groove 13 cooperates with the inner boss of the fixed cylinder 11 to restrict the radial rotation of the threaded rod 12. The threaded rod 12 drives the slider 2 to rise, thereby adjusting the detection position.

[0024] The instrument fixture 5 includes a second slider 51, which is slidably connected to the vertical slide rail 4. A slide rod 52 is slidably connected inside the second slider 51. The two ends of the slide rod 52 are respectively connected to the limiting piece 53 and the clamping piece 54. A spring 55 is sleeved on the slide rod 52 between the limiting piece 53 and the second slider 51. There are two sets of slide rod 52, limiting piece 53, clamping piece 54 and spring 55, which are arranged in opposite directions. The two sets of slide rods 52 are arranged parallel to each other in the vertical direction.

[0025] When clamping the detector, pull one of the clamping plates 54 to place the detector between the two clamping plates 54. The limiting plate 53 drives the spring 55 to compress. Under the action of the spring 55's return force, the two clamping plates 54 clamp the detector.

[0026] The displacement mechanism 6 includes a motor 61. Two motors 61 are respectively connected to one end of the horizontal slide rail 3 and the vertical slide rail 4. The motors 61 are connected to lead screws 62. The two lead screws 62 are respectively rotatably connected to the horizontal slide rail 3 and the vertical slide rail 4. The two lead screws 62 are respectively threadedly connected to slider 1 2 and slider 2 51.

[0027] Two motors 61 drive two lead screws 62 to rotate respectively. Both lead screws 62 are axially limited by the horizontal slide rail 3 and the vertical slide rail 4. One lead screw 62 drives the slider 1 2 to move through the thread, and the other lead screw 62 drives the slider 2 51 to move through the thread, thus completing the adjustment of the measuring point position.
