Description

Technical Field

[0001] This utility model relates to the field of surface flatness detection technology, and in particular to a device for detecting the surface flatness of precast concrete components. Background Technology

[0002] Precast concrete components refer to concrete components that are pre-cast and cured in a factory or dedicated production site according to design requirements. After reaching a certain strength, they are transported to the construction site for installation and assembly. Surface flatness testing refers to the process of measuring and evaluating whether the surface of a concrete component is flat and whether there are defects such as unevenness, misalignment, or bulges.

[0003] Patent application publication number CN215168167U discloses a suspended laser level lifting device. It includes a support structure and a lifting mechanism, on which the laser level is mounted. The support structure comprises two parallel steel pipes, a first steel pipe and a second steel pipe, both mounted on a lower floor deck and an upper floor deck. The lifting mechanism includes a base plate, a motor, a lead screw and a nut, and a lifting plate sleeved on the lead screw and connected by the nut. The laser level is mounted on the lifting plate. When using this patent, the laser level is mounted on the lifting plate, and the motor's output shaft drives the lead screw to rotate via a coupling, thereby driving the lifting plate and the laser level to move for detection. However, this existing patent lacks vibration damping. In construction sites or industrial environments, there are vibrations caused by the operation of mechanical equipment and personnel movement, and the motor also generates some vibration during operation. Frequent vibrations can affect the detection effect of the laser level, leading to deviations in the measurement results.

[0004] In view of the existing patents, there is a need to provide a surface flatness detection device for precast concrete components with shock absorption function. Utility Model Content

[0005] To overcome the shortcomings of existing patents that lack vibration damping function, and which are subject to vibration caused by the operation of mechanical equipment and personnel movement in construction sites or industrial environments, as well as vibration generated during motor operation, frequent vibration can affect the detection effect of laser level and lead to deviations in measurement results, this utility model provides a surface flatness detection device for precast concrete components with vibration damping function.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a surface flatness testing device for precast concrete components, comprising a mounting frame, a laser level, connecting ports, a lens, and a lifting mechanism. The laser level is mounted on the mounting frame, which has two connecting ports and a lens. The lifting mechanism is also mounted on the mounting frame. Furthermore, the device includes a first anti-vibration pad, an elastic element, a second anti-vibration pad, and a base shell. The second anti-vibration pad is mounted on the base shell, and the first anti-vibration pad is mounted on the lifting mechanism. Two elastic elements connect the first and second anti-vibration pads.

[0007] In a preferred embodiment of the present invention, the lifting mechanism includes a connecting frame, guide rods, a mounting plate, and an electric cylinder. Four guide rods are fixedly connected to the mounting plate, and an electric cylinder is mounted on the mounting plate. The connecting frame is mounted on the telescopic rod of the electric cylinder, and the connecting frame slides on the four guide rods.

[0008] In a preferred embodiment of this utility model, a baffle is also included, and the baffle is attached to the laser level.

[0009] In a preferred embodiment of the present invention, a soft pad is also included, with the soft pad disposed between the connecting frame and the mounting frame.

[0010] In a preferred embodiment of this utility model, the baffle is V-shaped.

[0011] In a preferred embodiment of this utility model, four reinforcing ribs are provided between the mounting bracket and the laser level.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The second shock-absorbing pad first absorbs the low-frequency large-amplitude vibration transmitted from the ground. The mechanical vibration generated during the operation of the equipment is absorbed and buffered by the first shock-absorbing pad and the elastic element, so that the laser level remains stable and the laser emitter will not deviate due to slight shaking, thereby ensuring the accuracy of the measurement data.

[0013] 2. By activating the electric cylinder, the extension rod of the electric cylinder extends, driving the connecting frame, mounting frame and laser level to move upward, thereby automatically performing planar inspection on the surface of the precast concrete component, reducing the influence of human factors on the measurement results.

[0019] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0020] Example 1: A device for detecting the surface flatness of precast concrete components, see reference. Figures 1-4 As shown, the device includes a mounting frame 1, a laser level 2, a connection port 3, a lens 4, and a lifting mechanism. The laser level 2 is bolted to the top of the mounting frame 1. Two connection ports 3 are located on the left side of the laser level 2, and the lens 4 is located on the right side of the laser level 2. The lifting mechanism for adjusting the height is located at the bottom of the mounting frame 1. The device also includes a first anti-vibration pad 10, an elastic element 11, a second anti-vibration pad 12, and a bottom shell 13. The second anti-vibration pad 12 is located on the top of the bottom shell 13. The first anti-vibration pad 10 is located on the lifting mechanism. Two elastic elements 11, which are damping springs, are connected between the first anti-vibration pad 10 and the second anti-vibration pad 12.

[0021] See Figure 1 and Figure 4 As shown, it also includes a baffle 14, which is attached to the laser level 2.

[0022] See Figure 1 and Figure 4 As shown, the baffle 14 is V-shaped, which can better block external light.

[0023] See Figure 1 and Figure 4 As shown, four reinforcing ribs are provided between the mounting bracket 1 and the laser level 2 to increase the stability of the laser level 2.

[0024] When this device is needed, first move the equipment to the designated location, then connect the power supply and connecting cable to the laser level 2, start the laser level 2, so that the laser is emitted from the lens 4 to detect the flatness of the concrete precast surface. The baffle 14 can prevent external light from interfering with the laser, thus ensuring the accuracy of the detection. At the same time, the lifting mechanism performs automatic detection, and the second shock absorber can absorb the low-frequency large-amplitude vibration transmitted from the ground. During the operation of the equipment, the mechanical vibration generated will be absorbed and buffered by the first shock absorber and the elastic element 11, so that the laser level 2 remains stable and the laser emitter will not be deflected due to slight shaking, thereby ensuring the accuracy of the measurement data.

[0025] Example 2: Based on Example 1, refer to Figure 1 and Figure 2 As shown, the lifting mechanism includes a connecting frame 6, guide rods 7, mounting plate 8, and electric cylinder 9. Guide rods 7 are symmetrically welded to the top left and right sides of the mounting plate 8. Electric cylinder 9 is bolted to the top of the mounting plate 8. The connecting frame 6 is mounted on the telescopic rod of the electric cylinder 9. The connecting frame 6 slides on the four guide rods 7. Mounting frame 1 is mounted on the connecting frame 6. The first anti-vibration pad 10 is set on the mounting plate 8.

[0026] See Figure 2 As shown, it also includes a soft pad 5. A soft pad 5 is provided between the connecting bracket 6 and the mounting bracket 1 to prevent wear between the mounting bracket 1 and the connecting bracket 6.

[0027] When using the lifting mechanism, the electric cylinder 9 is activated, and the telescopic rod of the electric cylinder 9 extends, causing the connecting frame 6, the mounting frame 1, and the laser level 2 to move upward. This enables automatic planar inspection of the surface of the precast concrete component, reducing the influence of human factors on the measurement results. After the inspection is completed, the laser level 2 and the electric cylinder 9 can be turned off.
