Additionally, all embodiments can be used in combination with each other.

[0032] Please refer to Figures 1 to 7 , the present invention provides a technical solution:

[0033] Embodiment 1

[0034] A device for controlling the elevation of concrete pouring, comprising: a mounting base 1, a suspension rod 4, and a reflection assembly 6.

[0035] Specifically, a gantry frame 2 is fixedly connected to the upper surface of the installation base 1. A rotating base 3 is fixedly connected to the lower surface of the gantry frame 2. The installation base 1 is placed on the ground, and the height of the rotating base 3 is higher than the surface of the concrete layer to be poured.

[0036] Secondly, a suspension rod 4 is suspended below the rotating base 3, and the upper end of the suspension rod 4 is rotatably connected to the rotating base 3. The suspension rod 4 can maintain a vertical suspension under the action of gravity. A elevation scale line 5 is provided on the surface of the suspension rod 4 along its own length direction for detecting and controlling the elevation line.

[0037] Furthermore, the reflection assembly 6 includes a movable sleeve 61 movably sleeved outside the suspension rod 4. Four reflecting plates 62 distributed in a circular array are fixedly connected to the outer side wall of the movable sleeve 61. The four reflecting plates 62 are spliced into a cross shape. Reflective coatings 63 are coated on both side surfaces of the reflecting plates 62. The reflective coatings 63 can reflect the laser rays emitted by the laser emitter. When the device is in use, an external laser emitter and the device are respectively placed on both sides of the site. As Figure 7 shown, the laser emitted by the laser emitter passes through the site where the concrete needs to be poured and irradiates on the surface of the reflective coating 63 of the device. Since the adjacent two reflective coatings 63 are perpendicular to each other, the laser can be reflected back in a direction parallel to the incident direction after being reflected by the adjacent two reflective coatings 63. The reflected laser falls on the receiving target. By observing whether the heights of the incident point position and the reflected point position are flush, it can be determined whether the laser emitted by the laser emitter is horizontal. By observing the scale numbers on the elevation scale line 5, the height position of the laser can be determined, so as to realize the elevation control of the poured concrete layer. A viewing window 64 for observing the elevation scale line 5 is provided on the surface of the movable sleeve 61, and the viewing window 64 is convenient for the staff to observe the scale on the elevation scale line 5.

[0038] Embodiment Two

[0039] On the basis of Embodiment One, in order to support the reflection assembly 6, the present application further has a limit gear ring 65 fixedly connected to the lower end surface of the movable sleeve 61. A support ring 8 is arranged below the limit gear ring 65. The support ring 8 is movably sleeved outside the suspension rod 4. A mating gear ring 11 is fixedly connected to the upper surface of the support ring 8. The mating gear ring 11 and the limit gear ring 65 are meshed. The support ring 8 can move up and down outside the suspension rod 4 to control the height position of the reflection assembly 6, and the meshing of the mating gear ring 11 and the limit gear ring 65 can also prevent the reflection assembly 6 from rotating randomly.

[0040] Embodiment Three

[0041] Based on Embodiment 2, in order to prevent the support ring 8 from rotating relative to the suspension rod 4, the present application further has a hollow slot 41 opened inside the lower end of the suspension rod 4. A limiting chute 42 is penetrated through the inner side wall of the hollow slot 41. A connecting block 10 is fixedly connected to the inner side wall of the support ring 8. The connecting block 10 penetrates through the limiting chute 42 and extends into the inner cavity of the hollow slot 41. The setting of the connecting block 10 is used to prevent relative rotation between the support ring 8 and the suspension rod 4.

[0042] Embodiment 4

[0043] Based on Embodiment 3, in order to adjust the height position of the reflection assembly 6, the present application further has an adjusting screw rod 7 rotatably arranged in the inner cavity of the hollow slot 41. A sliding ring 9 is sleeved on the outer side of the adjusting screw rod 7 by threads. The sliding ring 9 is located in the inner cavity of the hollow slot 41. The sliding ring 9 is concentric with the support ring 8 and is fixedly connected to each other through the connecting block 10. By screwing the adjusting screw rod 7, the sliding ring 9 can be driven to slide in the inner cavity of the hollow slot 41, and then drive the support ring 8 to slide along the length direction of the suspension rod 4, so as to adjust the height position of the reflection assembly 6.

[0044] Embodiment 5

[0045] Based on Embodiment 4, in order to prevent the adjusting screw rod 7 from detaching from the inner cavity of the hollow slot 41, the present application further has a fixed flange 43 fixedly connected to the lower end of the suspension rod 4. An installation flange 14 is fixedly connected to the lower surface of the fixed flange 43. The lower end of the adjusting screw rod 7 movably penetrates through the installation flange 14 and is fixedly connected to an adjusting knob 15. A limiting retaining ring 16 is arranged in the lower end inner cavity of the hollow slot 41. The limiting retaining ring 16 fits against the upper surface of the installation flange 14 and is fixedly connected to the adjusting screw rod 7. After the installation flange 14 abuts against the limiting retaining ring 16, the adjusting screw rod 7 can be prevented from sliding in the inner cavity of the hollow slot 41 and detaching from the hollow slot 41.

[0046] Embodiment 6

[0047] Based on Embodiment 5, in order to prevent the reflection assembly 6 from tilting, the present application further has a spherical connecting piece 12 fixedly connected to the upper end of the suspension rod 4. The spherical connecting piece 12 is located inside the rotating base 3 and is rotatably connected thereto. An opening for the suspension rod 4 to pass through is arranged on the lower side of the rotating base 3. A rubber pad 13 is adhered to the inner wall of the rotating base 3. Therefore, the suspension rod 4 can be kept vertically arranged under the action of gravity, so as to ensure that the reflection assembly 6 will not affect the reflection of the laser due to tilting during use.

[0048] Embodiment 7

[0049] On the basis of Embodiment VI, in order to fix the rotating base 3, the present application further has a connecting seat 17 fixedly connected to the upper part of the surface of the rotating base 3. The connecting seat 17 is installed in the middle of the gantry frame 2 by bolts. A reinforcing plate is fixedly arranged between the rotating base 3 and the connecting seat 17. The connecting seat 17 is provided to fix the rotating base 3 and the gantry frame 2, preventing the rotating base 3 from moving.

[0050] Embodiment VIII

[0051] On the basis of Embodiment VII, in order to ensure that the mounting base 1 is as horizontal as possible, the mounting base 1 of the present application is set to be square, and a weight-reducing through groove is provided in the middle. Threaded leveling bolts 18 are respectively arranged through the four corners of the mounting base 1. The lower ends of the leveling bolts 18 are fixedly connected with support foot pads 19 located below the mounting base 1. By turning the leveling bolts 18, the distance between the support foot pads 19 and the mounting base 1 can be adjusted, so as to ensure that the mounting base 1 can be kept as horizontal as possible.

[0052] Embodiment IX

[0053] On the basis of Embodiment VIII, the scale numbers on the elevation scale line 5 of the present application are arranged along the length direction of the suspension rod 4, and multiple groups of scale numbers are provided, and are distributed on the surface of the suspension rod 4 centered on the axis of the suspension rod 4. The scale marks on the elevation scale line 5 surround the suspension rod 4 in a circle and connect the multiple groups of scale numbers one by one, ensuring that the staff can view the scale numbers on the elevation scale line 5 through the viewing window 64.
