[0016] Furthermore, a limiting rod is connected to the other side of the clamping plate, and the limiting rod is slidably connected to the supporting plate.
[0017] The present invention has the following beneficial effects:
[0018] 1. When the linear module drives the lifting seat to move, when the laser detection head inside the rotating seat detects the outside of the steel bar, the lifting seat moves to the lower part of the steel bar, and the lifting seat will squeeze the guide plate to make it slide under the limit of the guide column. At this time, the groove on the side of the guide plate can be used to guide the slide bar, so that the screw sleeves on both sides can move to both sides under the limit of the support plate, thereby driving the clamping plate to loosen the lower part of the steel bar through the screw rod, and automatically perform the avoidance operation, thereby increasing the range of laser detection, and when the lifting seat drives the linear module to move upward, the reset spring will push the guide plate under the limit of the guide column to reset it. Similarly, the clamping plate can automatically clamp the end of the steel bar, which is beneficial to improve the stability during the steel bar detection process. When the linear module drives the lifting seat to move to the upper part of the steel bar, the upper clamping plate can also automatically loosen the steel bar, further expanding the detection range.
[0019] 2. When positioning steel bars of different thicknesses, the first driving gear, the transmission sleeve and the second driving gear can be used to make the upper driven gear rotate together with the lower driven gear when located at different heights, so that the screw can be driven to rotate through the limit plate, and the support plate will limit the rotation direction of the screw sleeve. Therefore, when the screw rotates, the position of the clamping plate at its end can be controlled, so that steel bars of different thicknesses can be clamped, which is beneficial to improving the use range of the equipment and improving the stability during clamping through the rubber pad. The limit rod can prevent the clamping plate from rotating, and all the clamping plates can be moved at the same time during adjustment, thereby improving the efficiency of clamping. After adjustment, since the screw can slide on the outside of the limit plate, it will not cause motion interference to the avoidance component.
[0020] 3. When the present invention detects steel bars of different lengths, the lower end of the steel bar is first placed in the limit seat at the top of the fixed frame. At this time, it is convenient to center it under the guidance of the conical groove of the limit seat, and when the electric cylinder drives the buffer plate to move downward, the limit seat at the bottom of the movable frame contacts the upper part of the steel bar, and the upper part of the steel bar can be limited. Therefore, when the upper or lower clamping plate releases the steel bar, the unclamped end of the steel bar can be limited by the limit seat to maintain the stability of the steel bar. In the process of the movable frame moving downward, the electric push rod can also be contracted, thereby driving the rotating ring to rotate, and the clamping plate can be pulled by the connecting rod to separate it from the tooth plate, so that the tooth plate and the buffer plate can slide. Therefore, the buffer spring can be used to buffer the movable frame and the buffer plate, which is beneficial to improve the fault tolerance rate when the movable frame moves, and avoid the electric cylinder extending too long to crush the steel bar. When the top of the steel bar contacts the upper limit seat, the electric push rod is extended again, and the clamping plate can clamp the tooth plate tightly, thereby avoiding the vibration of the buffer spring affecting the stability during positioning.

[0035] When in use, the linear module 4 drives the lifting seat 5 to move, so that the laser detection head 810 inside the rotating seat 809 detects the outside of the steel bar. The laser detection head 810 detects the distance between each point on the steel bar and it, and cooperates with the external summary processing equipment to process the data, and finally realizes the operation of measuring the deformation of the steel bar.

The guide column 601 is fixed at both ends of the fixing frame 2 and the adjustment component 3, and the return spring 602 is sleeved on the outer side of the guide column 601. The end of the guide column 601 is slidably connected to the guide plate 603, and the guide plate 60 3 is slidably connected to a slide rod 604, one end of the slide rod 604 is fixed with a screw sleeve 605, and the outer side of the screw sleeve 605 is slidably connected to a support plate 606, the inner thread of the screw sleeve 605 is connected to a screw rod 607, and one end of the screw rod 607 is rotatably connected to a clamping plate 608, one side of the clamping plate 608 is provided with a rubber pad 609, and the other side of the clamping plate 608 is connected to a limiting rod 610, and the limiting rod 610 is slidably connected to the support plate 606.
[0037] See also Figure 1 to Figure 2 The adjusting component 3 includes an electric cylinder 301, a buffer plate 302, a tooth plate 303 and a buffer spring 304. The electric cylinder 301 is fixed on the top of the frame 1, and the buffer plate 302 is connected to the bottom of the electric cylinder 301. The two ends of the buffer plate 302 are internally slidably connected with the tooth plate 303, and the buffer spring 304 is sleeved on the outer side of the lower end of the tooth plate 303; a movable frame 305 is fixed to the bottom of the tooth plate 303, and the two ends of the movable frame 305 are internally rotatably connected with the limiting sleeve 306, and the middle parts of the movable frame 305 and the fixed frame 2 are fixed with a limiting seat 307, and the middle groove of the limiting seat 307 is conical; the top of the buffer plate 302 is rotatably connected with an electric push rod 308, and the end of the electric push rod 308 is rotatably connected with a rotating ring 309, and the rotating ring 309 is rotatably connected to the buffer plate 302.
[0038] The adjustment assembly 3 further includes a connecting rod 310 and a clamping plate 311 . The two ends of the rotating ring 309 are rotatably connected to the connecting rod 310 , and the end of the connecting rod 310 is rotatably connected to the clamping plate 311 , and the clamping plate 311 is slidably connected to the buffer plate 302 .
[0039] The specific operation is as follows: first, the lower end of the steel bar is placed in the limiting seat 307 on the top of the fixed frame 2. At this time, it is convenient to center it under the guidance of the conical groove of the limiting seat 307. When the electric cylinder 301 drives the buffer plate 302 to move downward, the limiting seat 307 at the bottom of the movable frame 305 contacts the upper part of the steel bar, and the upper part of the steel bar can be limited. In the process of the movable frame 305 moving downward, the electric push rod 308 can be controlled to contract, thereby driving the rotating ring 309 to rotate, and the clamping plate 311 can be pulled by the connecting rod 310 to separate it from the tooth plate 303, so that the tooth plate 303 and the buffer plate 302 can slide. Therefore, the buffer spring 304 can be used to buffer the movable frame 305 and the buffer plate 302, which is conducive to improving the fault tolerance rate when the movable frame 305 moves and avoiding crushing the steel bar.
[0040] Then, when the top of the steel bar contacts the upper limit seat 307, the electric push rod 308 is extended, and the clamping plate 311 can clamp the tooth plate 303 at this time, so as to avoid the stability of positioning affected by the vibration of the buffer spring 304. Later, during the detection process, the linear module 4 will drive the lifting seat 5 to move to detect the outside of the steel bar, and when the lifting seat 5 moves to the lower part of the steel bar, the lifting seat 5 will squeeze the guide plate 603 to make it slide under the limit of the guide column 601. At this time, the groove on the side of the guide plate 603 can be used to guide the sliding rod 604, so that the screw sleeves 605 on both sides can move to both sides under the limit of the support plate 606. The screw rod 607 drives the clamping plate 608 to loosen the lower part of the steel bar and automatically perform the avoidance operation. When the lifting seat 5 drives the linear module 4 to move upward, the reset spring 602 will push the guide plate 603 under the limit of the guide column 601 to reset it. Similarly, the clamping plate 608 can automatically clamp the end of the steel bar, which is beneficial to improve the stability of the steel bar detection process. When the linear module 4 drives the lifting seat 5 to move to the upper part of the steel bar, the upper clamping plate 608 can also automatically loosen the steel bar. When the upper or lower clamping plate 608 loosens the steel bar, the limit seat 307 can also be used to limit the unclamped end of the steel bar to maintain the stability of the steel bar.
[0041] In some embodiments, the fixed frame 2 and the movable frame 305 are connected to the two ends of the synchronization assembly 7, see Figures 3 to 7 .
[0042] The synchronization component 7 includes a dual-axis motor 701, a bevel gear commutator 702, a transmission rod 703 and a first driving gear 704. The dual-axis motor 701 is fixed in the lower center of the fixed frame 2, and the two ends of the dual-axis motor 701 are connected to the bevel gear commutator 702, the top of the bevel gear commutator 702 is connected to the transmission rod 703, and the first driving gear 704 is fixed to the lower outer side of the transmission rod 703. The synchronization component 7 also includes a transmission sleeve 705, a second driving gear 706, a driven gear 707 and a limit plate 708. The transmission sleeve 705 is slidably connected to the upper outer side of the transmission rod 703, and the second driving gear 706 is fixed to the outer side of the transmission sleeve 705, and the transmission sleeve 705 is rotatably connected to the movable frame 305. The first driving gear 704 and the second driving gear 706 are meshed with a driven gear 707 on one side, and a limit plate 708 is fixed to one side of the driven gear 707, and the limit plate 708 is slidably connected to the screw 607.
[0043] By the above arrangement, the electric cylinder 301 drives the buffer plate 302 to move upward, and the driving rod 801 can squeeze the limit block 802, so that the vertical rod 803 pushes the inclined plate 807, and the sliding sleeve 805 can pull the rotating seat 809 through the rotating plate 808 to rotate it to an open state, so as to facilitate the placement of the steel bar in the middle of the rotating seat 809. In this process, as the buffer plate 302 moves downward, the driving rod 801 will separate from the limit block 802. At this time, the positioning spring 806 will push the sliding sleeve 805, and the rotating seat 809 can be driven to rotate at the end of the fixed rod 804 through the rotating plate 808. In the process of positioning the steel bar, the rotating seats 809 at both ends can be automatically closed, so that the multiple laser detection heads 810 on the inside can detect the outside of the steel bar without additional opening and closing operations, which is conducive to improving the convenience during operation.
[0044] During positioning, the dual-axis motor 701 is started to drive the transmission rods 703 at both ends to rotate through the bevel gear commutator 702. At this time, the upper driven gear 707 can rotate together with the lower driven gear 707 when located at different heights through the first driving gear 704, the transmission sleeve 705 and the second driving gear 706, and the screw 607 can be driven to rotate through the limit plate 708, and the support plate 606 will limit the rotation direction of the screw sleeve 605. Therefore, when the screw 607 rotates, the position of the end clamp 608 can be controlled, so that steel bars of different thicknesses can be clamped, which is beneficial to improving the scope of use of the equipment, and the stability during clamping is improved through the rubber pad 609, while the limit rod 610 can prevent the clamp 608 from rotating. At the same time, all the clamps 608 can be moved simultaneously during adjustment, thereby improving the efficiency during clamping.
[0045] In summary, the following method is used to measure the steel bar deformation using the steel bar deformation laser measuring device for civil engineering of the present invention:
[0046] First, the electric cylinder 301 drives the buffer plate 302 to move upward, thereby squeezing the limit block 802 through the driving rod 801, so that the vertical rod 803 pushes the inclined plate 807, and the sliding sleeve 805 pulls the rotating seat 809 through the rotating plate 808, so as to facilitate placing the steel bar in the middle of the rotating seat 809;
[0047] Next, the lower end of the steel bar is placed in the limiting seat 307 at the top of the fixed frame 2. At this time, it is convenient to center it under the guidance of the conical groove of the limiting seat 307. When the electric cylinder 301 drives the buffer plate 302 to move downward, the limiting seat 307 at the bottom of the movable frame 305 contacts the upper part of the steel bar, and the upper part of the steel bar can be limited. In this process, as the buffer plate 302 moves downward, the driving rod 801 will separate from the limiting block 802. At this time, the positioning spring 806 will push the sliding sleeve 805, and the rotating seat 809 can be driven to rotate at the end of the fixed rod 804 through the rotating plate 808, so that the rotating seats 809 at both ends are automatically closed.
[0048] Then, during the downward movement of the movable frame 305, the electric push rod 308 is controlled to contract, thereby driving the rotating ring 309 to rotate, and the clamping plate 311 can be pulled through the connecting rod 310 to separate it from the tooth plate 303, so that the tooth plate 303 and the buffer plate 302 can slide, and the buffer spring 304 is used to buffer the movable frame 305 and the buffer plate 302; when the top of the steel bar contacts the upper limit seat 307, the electric push rod 308 is extended, and the clamping plate 311 can clamp the tooth plate 303 at this time, so as to avoid the vibration of the buffer spring 304 affecting the stability during positioning, and then, the dual-axis motor 701 is started to make it pass The bevel gear commutator 702 drives the transmission rods 703 at both ends to rotate. At this time, the first driving gear 704, the transmission sleeve 705 and the second driving gear 706 enable the upper driven gear 707 to rotate together with the lower driven gear 707 when located at different heights, and the screw 607 can be driven to rotate through the limit plate 708, and the support plate 606 will limit the rotation direction of the screw sleeve 605. Therefore, when the screw 607 rotates, the position of the clamping plate 608 at its end can be controlled, so that steel bars of different thicknesses can be clamped, and the stability during clamping can be improved through the rubber pad 609, and the limit rod 610 can prevent the clamping plate 608 from rotating;
[0049] Afterwards, the linear module 4 drives the lifting seat 5 to move, so that the laser detection head 810 inside the rotating seat 809 detects the outside of the steel bar, and when the lifting seat 5 moves to the lower part of the steel bar, the lifting seat 5 will squeeze the guide plate 603 to make it slide under the limit of the guide column 601. At this time, the groove on the side of the guide plate 603 can be used to guide the slide bar 604, so that the screw sleeves 605 on both sides can move to both sides under the limit of the support plate 606, so that the clamping plate 608 is driven by the screw rod 607 to loosen the lower part of the steel bar, and the steel bar is automatically When the lifting seat 5 drives the linear module 4 to move upward, the reset spring 602 will push the guide plate 603 under the limit of the guide column 601 to reset it. Similarly, the clamping plate 608 can automatically clamp the end of the steel bar to improve the stability during the steel bar detection process. When the linear module 4 drives the lifting seat 5 to move to the upper part of the steel bar, the upper clamping plate 608 can also automatically release the steel bar. When the upper or lower clamping plate 608 releases the steel bar, the unclamped steel bar end can be limited by the limit seat 307.
[0050] Finally, the laser detection head 810 detects the distance between each point on the steel bar and it, and cooperates with the external summary processing equipment to process the data, and finally realizes the measurement operation.
