Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering detection, and in particular to a device and method for measuring the thickness of a building floor. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The floor thickness gauge is an instrument mainly used to measure the thickness of concrete structures such as floors, shear walls, beams, columns and other non-ferromagnetic media. The transmitting probe and the receiving probe are respectively placed on the upper and lower sides of the measured floor. The value displayed on the instrument is the distance between the two probes. Only the receiving probe needs to be moved. However, the traditional floor thickness gauge has poor performance, is not easy to move, has poor protection effect, and is easily damaged when carried.

[0045] The transmission mechanism 8 also includes a guide rod 806 and a connecting frame 803. The transmission plate 801 is symmetrically arranged on the upper part of the mounting plate 3. A guide block 807 is arranged on the upper part of the transmission plate 801. The guide rod 806 passes through the guide block 807, and the guide block 807 can slide along the guide rod 806. The two ends of the guide rod 806 are fixedly connected to the inner wall of the storage frame 1. The guide block 807 is arranged in coordination with the guide rod 806 to limit the moving direction of the transmission plate 801 and provide support for it to improve its stability. A transmission groove 802 is provided along the diagonal direction of the transmission plate 801, and the length of the transmission groove 802 is less than the length of the diagonal line; a connecting frame 803 is provided on the top of the baffle 5, and the connecting frame 803 is an L-shaped structure.

Guide grooves are provided on the top inner walls of the left and right sides of the storage frame 1, and the connecting frame 803 and the guide grooves are relatively slidably arranged. When the transmission plate 801 is driven by the driving block 703, the transmission plate 801 can reciprocate along a first direction relative to the storage frame 1.

[0047] like Figure 7 As shown, a limiting frame 805 is also provided on the connecting frame 803. The limiting frame 805 is two relatively open U-shaped structures. The limiting frame 805 is engaged with the mounting plate 3, so that the mounting plate 3 is clamped and limited between the two limiting frames 805 to prevent it from shaking when subjected to external force. When the thickness gauge probe 2 is stored in the storage frame 1, the transmission plate 801 is driven to move by the driving mechanism 7. The transmission plate 801 drives the two connecting frames 803 to approach each other through the cooperation of the transmission groove 802 and the transmission column 804. The connecting frame 803 drives the baffles 5 to approach each other until the two baffles 5 are closed to close the square hole 4; when the connecting frame 803 moves, it drives the limiting frame 805 to move synchronously, so that the limiting frame 805 approaches the thickness gauge body until the limiting frame 805 is engaged with the outer surface of the mounting plate 3, thereby improving the stability of the thickness gauge body when it is stored and preventing it from shaking and causing damage to it.

[0048] The storage frame 1 is provided with a control module and a signal transmission module, the control module is connected to the signal transmission module, the control module is also connected to the moving wheel 12, the driving motor 702, the winding motor 9 and the walking motor 13 respectively, the signal transmission module is also connected to the thickness gauge probe 2, the signal transmission module is used to send the test data of the thickness gauge probe 2 to the handheld control terminal 14, and at the same time receive the control signal from the handheld control terminal, the handheld control terminal 14 can be used to control the device and calculate the received test data, such as Figure 8 As shown, the handheld control terminal is integrated with a control handle 1401, a display 1402 and a signal antenna 1403.

At the same time, the display is a screen with a touch function, and the device can be debugged and controlled by clicking the display with fingers.

[0049] The thickness measurement method includes the following steps:

[0050] S1: Start the control module through the handheld control terminal 14 to control the travel motor 13 to drive the moving wheel 12 to transfer the device to the position to be detected.

[0051] S2: Start the control module through the handheld control terminal 14 to control the drive motor 702. When the drive motor 702 is running, it drives the drive screw 701 to rotate. The drive screw 701 drives the drive block 703 to move in the horizontal direction, thereby driving the transmission plate 801 to move. Through the matching arrangement of the transmission column 804 and the transmission slot 802, when the transmission plate 801 moves in the horizontal direction, the transmission column 804 is pushed to move to the side close to the inner wall of the storage frame 1 through the transmission slot 802.

The baffles 5 move away from each other, the square hole 4 is opened, and the connecting frame 803 drives the limit frame 805 to move during the movement, thereby releasing the limit locking state of the mounting plate 3; and when the baffle 5 moves, it drives the rotating shaft 502 and the connecting shaft 501 to move synchronously, and the rotating shaft 502 drives the connecting gear 504 to move synchronously. Since the position of the rack plate 505 is fixed, the connecting gear 504 drives the rotating shaft 502 to rotate during the movement, and the rotating shaft 502 drives the connecting shaft 501 to rotate through the transmission member 503, so that the connecting shaft 501 drives the cleaning brush 6 to rotate, thereby cleaning the dust and impurities at the inspection location.

[0052] S3: Start the control module through the handheld control terminal 14 to control the winding motor 9, so that the winding motor 9 reverses and drives the winding shaft 902 to rotate, and the connecting rope 10 is loosened. At this time, the thickness gauge probe 2 moves downward under the action of its own gravity, and moves out of the storage frame 1 through the through hole until it contacts the position to be detected.

[0053] S4: Start the control module through the handheld control terminal 14 to control the winding motor 9, so that the winding motor 9 rotates forward to drive the winding shaft 902 to rotate, and the connecting rope 10 is tightened. At this time, the thickness gauge probe 2 rises under the action of the connecting rope 10, and is stored in the storage frame 1 through the square hole 4 until the height of the limit frame 805, and the drive motor 702 is started, and the connecting frame 803 is driven to slide toward each other through the transmission mechanism 8 until the limit frame 805 is engaged with the mounting plate 3, so as to realize the storage of the thickness gauge probe and avoid the absorption of dust when moving in a harsh environment.

A thickness measuring method of a building floor thickness measuring device according to any one of claims 1 to 7, It is characterized in that The following steps are involved: S1: Control the walking motor to drive the moving wheel through the control module to move the device to the position to be detected; S2: Cleaning process: The driving motor is started through the control module. When the driving motor is running, it drives the driving screw to rotate. The driving screw drives the driving block to move in the horizontal direction, thereby driving the transmission plate to move. Through the coordinated arrangement of the transmission column and the transmission slot, when the transmission plate moves in the horizontal direction, the transmission column drives the connecting frame to move, and the connecting frame drives the baffle to move. The two baffles move away from each other, and the square hole is opened; when the baffle moves, it drives the rotating shaft and the connecting shaft to move synchronously, and the rotating shaft drives the connecting gear to move synchronously. Since the position of the rack plate is fixed, the connecting gear drives the rotating shaft to rotate during the movement. The rotating shaft drives the connecting shaft to rotate through the transmission member, so that the connecting shaft drives the cleaning brush to rotate, thereby cleaning the dust and impurities at the inspection location; S3: Release the thickness gauge probe process: start the winding motor through the control module, the winding motor reverses to drive the winding shaft to rotate, loosen the connecting rope, and the thickness gauge probe moves downward under its own gravity and moves out of the storage frame through the through hole until it contacts the position to be detected; S4: Process of storing the thickness gauge probe: Start the winding motor through the control module, so that the winding motor rotates forward to drive the winding shaft to rotate, tighten the connecting rope, and the thickness gauge probe rises and is stored in the storage frame through the square hole until it reaches the height of the limit frame. Start the drive motor and drive the connecting frame to slide toward each other through the transmission mechanism until the limit frame is engaged with the mounting plate.
