DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example 1

[0020] Reference Figure 1-4 The concrete flatness measuring device comprises a housing 1, a screw rod 2 is rotatably installed inside the housing 1, the end of the screw rod 2 is fixedly connected to an external motor, the screw rod 2 is a reciprocating screw rod, and the screw rod 2 can be driven to rotate by an external motor, a linkage block 3 is provided on the outer thread sleeve of the screw rod 2, and the rotation of the screw rod 2 can drive the linkage block 3 to move, and support rods 4 are slidably penetrated at both ends of the linkage block 3, and the length direction of the support rod 4 is vertically arranged and parallel to the length direction of the screw rod 2, and a detection block 6 is fixedly installed at the lower end of the support rod 4, and the movement of the linkage block 3 can drive the detection block 6 to move through the support rod 4. The movement of the detection block 6 can increase the detection range, and the detection block 6 can move back and forth horizontally while the housing 1 is moving, so that a wider range of the concrete surface can be detected at the same time. A first spring 5 is sleeved on the outer side of the lower end of the support rod 4. The lower end of the first spring 5 is fixedly connected to the detection block 6, and the upper end is fixedly connected to the linkage block 3. A connecting frame 7 is fixedly installed on the upper end of the support rod 4. A pair of mounting bars 13 are fixedly installed on the inner side of the housing 1. The length direction of the screw rod 2 is horizontally arranged and parallel to the length direction of the mounting bars 13. In the absence of external force, under the elastic force of the first spring 5, the detection block 6 is away from the linkage block 3, and the distance between the detection block 6 and the linkage block 3 is the largest. However, at this time, the fixed box 8 is not located in the middle of the inner side of the mounting bar 13. The fixed box 8 is set at a lower position. The pressing block 11 located below will be squeezed by the mounting bar 13, and the trigger switch 12 located below is triggered, and one of the alarm lights 14 flashes.

[0021] A trigger mechanism is fixedly installed inside the connecting frame 7, and the trigger mechanism is located between the mounting strips 13. The trigger mechanism includes a fixing box 8, and the fixing box 8 is fixedly installed inside the connecting frame 7. The mounting strips 13 are arranged horizontally in the length direction. The fixing box 8 and the second spring 10 are arranged vertically in the length direction and perpendicular to the length direction of the mounting strips 13. A partition 9 is fixedly installed inside the fixing box 8, and the second springs 10 are fixedly connected to both sides of the partition 9. A pressure block 11 is fixedly connected to the end of the second spring 10. The pressure block 11 is slidably arranged in the fixing box 8, and the end thereof extends through and extends to the outside of the fixing box 8. The end of the pressure block 11 will be away from the fixing box 8 under the elastic support of the second spring 10, and the end of the pressure block 11 is close to the mounting strip 13. A trigger switch 12 is fixedly installed at the end of the pressing block 11 located inside the fixed box 8, and an alarm light 14 is fixedly installed on the top of the shell 1. The alarm light 14 is electrically connected to the inside of the trigger switch 12 through a wire. When the trigger switch 12 is pressed, the power inside the alarm light 14 is turned on. There are two alarm lights 14, which are respectively connected to the trigger switches 12 on the upper and lower sides. The flashing lights of the two alarm lights 14 are different in color, which can distinguish whether the upper or lower trigger switch 12 is triggered.

[0022] As attached Figure 2 As shown in , at this time, the first spring 5 is in a compressed state, and in the fixed box 8, the trigger switches 12 on the upper and lower sides are not triggered, and the pressure blocks 11 on the upper and lower sides are not in contact with the mounting bar 13. At this time, both alarm lights 14 are not triggered. Here, this state is called a detection state, and the position of the detection block 6 in this state is called a detection position.

[0023] A roller mechanism is fixedly installed on both sides of the shell 1, and the roller mechanism includes a telescopic rod 17. The upper end of the telescopic rod 17 is fixedly installed on both sides of the shell 1, and the telescopic rod 17 is vertically arranged in the length direction. A fixed plate 16 is fixedly installed on the lower end of the telescopic rod 17. The fixed plate 16 is slidably arranged on one side of the shell 1, and a roller 15 is fixedly installed on the lower surface of the fixed plate 16. The measuring device is convenient to move through the roller 15. The height of the fixed plate 16 can be adjusted through the telescopic rod 17, so that the height of the roller 15 can be adjusted through the fixed plate 16, and then the distance between the detection block 6 and the concrete surface to be detected can be adjusted.

[0024] When there is no detection, the telescopic rod 17 is started to drive the fixed plate 16 to move downward, and the fixed plate 16 moves downward to drive the roller 15 to move downward, so that the distance between the detection block 6 and the ground becomes larger, and the detection block 6 does not contact the ground, which does not affect the movement of the device. At this time, the detection block 6 is located at the position farthest from the linkage block 3 under the elastic force of the first spring 5, and the trigger switch 12 located below is triggered, and one of the alarm lights 14 is in a flashing state. During detection, the telescopic rod 17 is started to drive the fixed plate 16 to move upward, and the fixed plate 16 moves upward to drive the roller 15 to move upward, so that the detection block 6 conflicts with the concrete surface to be detected, the first spring 5 is squeezed, the support rod 4 drives the connecting frame 7 to move upward, and the connecting frame 7 drives the fixing box 8 to move upward, so that the fixing box 8 moves to the middle part of the installation bar 13. At this time, the pressure blocks 11 on the upper and lower sides just do not contact the installation bar 13, the two trigger switches 12 are not triggered, and the two alarm lights 14 are not triggered. At this time, the device is in the detection state, and the detection block 6 is located in the detection position. Then, the flatness of the concrete surface can be checked by moving the device.

[0025] Working principle: During the detection process, the concrete flatness measuring device conveniently pushes the shell 1 to move above the concrete surface to be detected through the roller 15, starts the telescopic rod 17 to drive the roller 15 to move through the fixed plate 16, so that the detection block 6 moves to the detection position. At this time, the device is in the detection state, pushes the shell 1 to move, and starts the screw rod 2 to drive the linkage block 3 to move. The movement of the linkage block 3 will drive the detection block 6 to move through the support rod 4; if the concrete surface is flat, the position of the detection block 6 will not change, and the two alarm lights 14 will not be triggered; if the concrete surface is concave, the detection block 6 will move downward under the elastic support of the first spring 5, and the support rod 4 will drive the fixing box 8 to move downward through the connecting frame 7, and the pressure block 11 located below will be squeezed by the mounting strip 13 If the concrete surface bulges upward, the detection block 6 will move upward, the first spring 5 will be compressed, the support rod 4 will drive the fixing box 8 to move upward through the connecting frame 7, and the pressing block 11 located above will be squeezed and moved by the pressing state 13, the second spring 10 above will be compressed, the trigger switch 12 located above will be squeezed and triggered, and the corresponding warning light 14 will flash. The inspection personnel can judge the flatness state of the concrete surface according to the state of the warning light 14, and can timely discover the specific location of the defects on the concrete surface, and can also roughly judge the overall flatness state of the concrete surface according to the frequency and time of the flashing of the warning light 14.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
