[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] The following is combined with Figures 1 to 3 This invention describes a rebar cage annular rebar detection device.
[0024] like Figures 1 to 3 As shown in the figure, the rebar cage annular rebar detection device provided in this embodiment of the present invention includes a support frame and a positioning rod 2.
[0025] Specifically, the upper end of the support frame is provided with at least three support rods 1, which extend horizontally and are distributed radially, with the axes of all support rods 1 intersecting at a single point. Six, eight, or other support rods 1 can be provided to increase stability.
[0026] Positioning rods 2 are installed on support rods 1. There are at least two sets of positioning rods 2, and each rod in each set corresponds one-to-one with each support rod 1. That is to say, there are at least two positioning rods 2 on each support rod 1.
[0027] The positioning rods 2 on each support rod 1 are spaced apart along the axis of the support rod 1, and the position of each positioning rod 2 on the support rod 1 is adjustable along the axis of the support rod 1. By adjusting the position of the positioning rods 2 on the support rod 1, the positioning rods 2 of the same group can be located on the same circumference, and the positioning rods 2 of different groups can be located on different circumferences.
[0028] With this setup, during use, the position of the positioning rods 2 can be adjusted according to the target diameter of the annular rebar to be tested, ensuring that at least one set of positioning rods 2 is located on the same circumference with a diameter matching the target diameter of the annular rebar. The annular rebar to be tested is then placed within the circumferential area of the positioning rods 2. Based on the fitting gap between the annular rebar and the positioning rods 2, it can be visually determined whether the diameter of the annular rebar meets the requirements, thus enabling the testing of annular rebars with a single target diameter. By adjusting the position of the positioning rods 2, the testing of annular rebars with different target diameters can be achieved. Furthermore, different sets of positioning rods 2 can correspond to different target diameters, enabling simultaneous testing of annular rebars with different target diameters, avoiding repeated adjustments to the annular rebar testing device.
[0029] It should be noted that when using the same rebar cage ring-shaped rebar detection device to simultaneously detect the diameter of ring-shaped rebars with different target diameters, two operators can each be responsible for detecting one type of ring-shaped rebar. During the time interval between one operator removing a ring-shaped rebar from the device and that operator placing another ring-shaped rebar on it, the other operator can place their assigned target diameter ring-shaped rebar on the device for detection. In this way, by utilizing the time difference, two operators can simultaneously detect ring-shaped rebars of different target diameters on the same device, reducing the number of devices required and lowering tooling costs.
[0030] In this embodiment of the present invention, the rebar cage annular rebar detection device further includes a sliding locking mechanism 3, which is disposed between the positioning rod 2 and the support rod 1.
[0031] The sliding locking mechanism 3 can switch between an unlocked state and a locked state. When the sliding locking mechanism 3 is switched to the unlocked state, the positioning rod 2 can slide back and forth relative to the support rod 1 along the axis of the support rod 1 to adjust the position of the positioning rod 2. When the sliding locking mechanism 3 is switched to the locked state, it can restrict the sliding of the positioning rod 2 on the support rod 1, so that the positioning rod 2 and the support rod 1 are relatively fixed.
[0032] In this embodiment, the sliding locking mechanism 3 includes a slide groove 4, a slider 6, a first fastener 7, and a locking member 8.
[0033] A groove 4 is provided on the support rod 1, extending from one end of the support rod 1 to the other along its axial direction. A slider 6 is embedded in the groove 4 and can slide back and forth within the groove 4. A positioning rod 2 is placed on the slider 6. As the slider 6 slides along the groove 4, it can cause the positioning rod 2 to move relative to the support rod 1, thereby adjusting the position of the positioning rod 2.
[0034] Sliding holes 5 are provided on opposite side walls of the slide groove 4, extending along the axial direction of the support rod 1. A through hole is provided on the slider 6, corresponding to the sliding hole 5. A first fastener 7 passes through the sliding hole 5 and the through hole, and a limiting block 11 is provided at its first end, abutting against one side of the support rod 1. A locking member 8 is threadedly connected to the second end of the first fastener 7, and abutting against the side of the support rod 1 away from the limiting block 11.
[0035] With this configuration, rotating the locking member 8 allows both the locking member 8 and the limiting block 11 to disengage from the support rod 1. At this time, the first fastener 7 can slide relative to the support rod 1 with the slider 6, corresponding to the unlocked state of the sliding locking mechanism 3. Reverse rotation of the locking member 8 causes both the locking member 8 and the limiting block 11 to abut against the support rod 1. At this time, the friction between the locking member 8 and the support rod 1, as well as the friction between the limiting block 11 and the support rod 1, fixes both the locking member 8 and the first fastener 7 relative to the support rod 1, thereby restricting the slider 6 from sliding relative to the support rod 1, corresponding to the locked state of the sliding locking mechanism 3.
[0036] In a specific embodiment, the first fastener 7 may be, but is not limited to, a bolt, and the locking member 8 may be, but is not limited to, a nut.
[0037] In some embodiments, at least two sliders 6 are provided in the groove 4, and each slider 6 corresponds to a positioning rod 2. That is, each slider 6 is mounted on the support rod 1 by a sliding locking mechanism 3, and the position of each slider 6 can be adjusted individually.
[0038] In other embodiments, each slider 6 is provided with at least two positioning rods 2, and the at least two positioning rods 2 can share a sliding locking mechanism 3 to achieve position adjustment and fixation.
[0039] In this embodiment of the invention, the support rod 1 is slidably connected to the support frame, and the sliding direction of the support rod 1 relative to the support frame is parallel to the axis of the support rod 1. The sliding of the support rod 1 relative to the support frame can cause the positioning rod 2 to slide relative to the support frame, increasing the position adjustment range of the support rod and further increasing the target diameter of the annular rebar that the rebar cage annular rebar detection device can be applied to, thus enhancing its adaptability.
[0040] Specifically, each support rod 1 can be connected to the support frame via a sliding bearing.
[0041] In this embodiment, the rebar cage annular rebar detection device further includes a locking mechanism, which is disposed between the support rod 1 and the support frame. The locking mechanism can selectively restrict the sliding of the support rod 1 relative to the support frame. Switching the locking mechanism to the locked state restricts the sliding of the support rod 1 relative to the support frame, thus fixing the support rod 1 and the support frame relatively. Switching the locking mechanism to the unlocked state allows the support rod 1 to slide back and forth relative to the support frame.
[0042] Specifically, a mounting base is provided on the support frame, located on one side of the support rod 1. The locking mechanism includes locking holes and locking rods. Multiple locking holes are provided on the support rod 1, spaced apart along the axis of the support rod 1. The locking rod is located on the mounting base and threadedly connected to it. The axis of the locking rod is parallel to the axis of the locking holes and perpendicular to the axis of the support rod 1. By turning the locking rod, it can be moved closer to or further away from the support rod 1. When the end of the locking rod is inside the locking hole, the locking mechanism is in a locked state; when the end of the locking rod is outside the locking hole, the locking mechanism is in an unlocked state.
[0043] Tighten the locking rod until it is completely outside the locking hole. At this point, the locking mechanism is in the unlocked state, and the support rod 1 can be slid to adjust its position. After adjusting the position of the support rod 1, tighten the locking rod until its end is inside the locking hole. At this point, the locking mechanism is in the locked state, ensuring the positional stability of the support rod 1.
[0044] In this embodiment of the invention, a length scale mark is provided on the support rod 1 to indicate the position of the positioning rod 2 for easy adjustment.
[0045] In this embodiment of the utility model, the support frame includes a support ring 9 and a support leg 10.
[0046] The center of the support ring 9 coincides with the intersection of the axes of each support rod 1, meaning that each support rod 1 is arranged radially along the support ring 9. Each support rod 1 is fixedly connected to the support ring 9.
[0047] Support legs 10 are located below support ring 9, and at least three support legs 10 are provided, with each support leg 10 spaced apart circumferentially along support ring 9. Each support leg 10 is fixedly connected to support ring 9, and the length of each support leg 10 is adjustable.
[0048] Each support leg 10 serves as a support for the support ring 9. The height of the support ring 9 can be adjusted by extending and retracting each support leg 10, making it suitable for operators of different heights, facilitating operation, and improving the operator's testing efficiency.
[0049] In this embodiment, the support leg 10 includes a first leg and a second leg. The axis of the first leg is parallel to the axis of the second leg, and the first leg and the second leg partially overlap. An adjustment mechanism is provided between the first leg and the second leg to selectively adjust the relative position of the first leg and the second leg.
[0050] In some embodiments, a hook and loop fastener is directly used as the adjustment mechanism. The hook and loop fastener has a button; pressing the button allows the first leg and the second leg to slide relative to each other.
[0051] In this embodiment, the adjustment mechanism includes a first connecting hole, a second connecting hole, and a second fastener.
[0052] A first connecting hole is provided on the first leg, and there are multiple first connecting holes, which are spaced apart along the axial direction of the first leg. A second connecting hole is provided on the second leg, and the second connecting hole can be directly opposite any of the first connecting holes.
[0053] By aligning the second connecting hole with different first connecting holes, the first leg and the second leg can have different relative positions.
[0054] After adjusting the relative positions of the first and second legs to align the second connecting hole with the corresponding first connecting hole, the second fastener passes through both the second connecting hole and the corresponding first connecting hole. Through the interaction between the second fastener and the first leg, and between the second fastener and the second leg, the first and second legs are relatively fixed, preventing the support leg 10 from being extended or retracted. When the support leg 10 needs to be extended or retracted, the second fastener can be removed.
[0055] To facilitate determining the fit between the annular rebar to be tested and the positioning post, in some embodiments, the annular rebar detection device for the rebar cage further includes a detection element, a controller, and an alarm. Each positioning post is equipped with a corresponding detection element, which is located on the side of the positioning post facing the central axis of the support ring 9. The detection element is used to detect the pressure or distance between the annular rebar and the positioning rod 2. Both the detection element and the alarm are electrically connected to the controller.
[0056] Taking the detection element's detection of the distance between the ring-shaped rebar and positioning rod 2 as an example, the controller, based on the detected distance, will activate the alarm when the detected distance exceeds a preset value, thus alerting the operator that the diameter of the ring-shaped rebar is unqualified. This setup allows for quick determination of whether the diameter of the ring-shaped rebar is acceptable, eliminating the need for the operator to survey every part of the rebar's circumference, significantly improving detection efficiency.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
