Description

Technical Field

[0001] This utility model relates to the field of testing tools, specifically a tool for testing the flatness of indoor tile laying in building construction. Background Technology

[0002] During building construction, after the indoor tiles are laid, workers usually use a level to check the flatness of the tiles. In practice, workers place the bubble level flat on the tile surface and observe whether the bubbles in the bubble level are in the center to determine the flatness. Although this method is low-cost, it requires workers to spend a long time to check, making the inspection inefficient. Utility Model Content

[0003] The purpose of this utility model is to provide a tool for testing the flatness of indoor tile laying in building construction, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A tool for testing the flatness of indoor tile laying during building construction, comprising:

[0006] A mobile vehicle body, on which a fixed plate is welded, and a lifting unit is installed on the fixed plate;

[0007] A movable seat connected to the fixed plate, the movable seat being driven to move vertically by a lifting unit;

[0008] A rotating shaft is coaxially rotatably connected to the movable seat, and a detection unit is provided at the lower end of the rotating shaft.

[0009] Furthermore, the lifting unit includes a lifting cylinder vertically installed at the bottom of the fixed plate, an ear block is fixedly connected to the periphery of the movable seat, and the cylinder rod of the lifting cylinder is drivenly connected to the ear block.

[0010] Furthermore, a motor is mounted on the fixed plate, and the output shaft of the motor drives a connecting shaft. The rotating shaft has a spline hole for the connecting shaft to extend and retract, and the connecting shaft is keyed to the spline hole.

[0011] Furthermore, the detection unit includes a mounting portion fixed to the lower end of the rotating shaft. A movable arm is horizontally inserted through the mounting portion and slides freely horizontally on the mounting portion. A detection pin is vertically inserted through one end of the movable arm and slides freely vertically on the movable arm. A mounting cover is provided on the upper surface of the movable arm. A pressure sensor is connected to the inner bottom wall of the mounting cover. An elastic compression component is provided between the upper end of the detection pin and the pressure sensor. The elastic compression component is used to generate a force on the pressure sensor when the detection pin moves upward, and the magnitude of the force changes proportionally to the stroke of the detection pin moving upward.

[0012] Furthermore, the elastic compression assembly includes a compression block that engages within the mounting cover. The compression block slides freely up and down within the mounting cover. A return spring is vertically mounted within the mounting cover. The two ends of the return spring in the direction of its elastic force respectively elastically abut against the compression block and the detection pin. The upper surface of the compression block abuts against the pressure sensor.

[0013] Furthermore, the lower end of the detection pin is rotatably fitted with a ball bearing.

[0014] Furthermore, a short pin is fixed to the outer wall of the extrusion block, and the mounting cover has an oblong hole for the short pin to be inserted.

[0015] Furthermore, the movable arm is driven by a translation component disposed on the movable seat to move horizontally along the radial direction of the movable seat.

[0016] Furthermore, the translation component includes a sliding pin vertically fixed to the upper surface of the moving arm, a fixed disk coaxially fixedly connected to the movable seat, a spiral groove being formed on the end face of the fixed disk, and the upper end of the sliding pin being inserted into the spiral groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention uses a mobile vehicle to move on the surface of the tile. During the movement, the rotating shaft drives the detection unit to rotate, enabling the detection unit to detect the flatness of the tile surface in multiple directions. Compared with the detection methods in the prior art, this invention reduces the physical labor caused by manual operation to a certain extent and improves the detection efficiency.

[0019] This invention uses a rotating shaft to drive a moving arm to rotate. During the rotation, the moving arm simultaneously moves in a straight line on the horizontal plane, which makes the actual movement trajectory of the detection pin spiral, thereby increasing the detection range of the detection pin and improving the detection efficiency to a certain extent.

[0020] This invention utilizes a detection pin that slides on the surface of a tile. The detection pin moves up and down along the surface of the tile, causing the detection pin to compress the return spring. This causes the elastic resistance of the return spring against the compression block to change, which in turn causes the compression force of the compression block against the pressure sensor to change. This allows the flatness of the tile surface to be detected based on the change in the pressure signal from the pressure sensor. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-7 This utility model provides a technical solution: a tool for testing the flatness of indoor tile laying in building construction, including a mobile vehicle 1 with four wheels installed at the bottom, a fixed plate 3 welded to the middle of the top of the mobile vehicle 1, a motor 2 vertically installed on the fixed plate 3, a connecting shaft 5 connected to the output shaft of the motor 2, two lifting cylinders 4 vertically installed on the lower surface of the fixed plate 3, the cylinder rod of the lifting cylinder 4 driving and connecting to the lug 14, the two lugs 14 are welded together to the movable seat 8, the movable seat 8 is coaxial with the output shaft of the motor 2, and a rotating shaft 9 is coaxially rotatably connected to the movable seat 8, the rotating shaft 9 has a blind hole spline hole, the connecting shaft 5 is inserted into the spline hole and is keyed to the spline hole, so that when the rotating shaft 9 rotates, it will drive the connecting shaft 5 to rotate, and at the same time the rotating shaft 9 can move relative to the connecting shaft 5 along its axial direction;

[0031] A mounting part 10 is welded to the lower end of the rotating shaft 9. A movable arm 11 is horizontally inserted through the mounting part 10, and the movable arm 11 slides freely horizontally on the mounting part 10. A detection pin 12 is vertically inserted through one end of the movable arm 11, and the detection pin 12 slides freely vertically on the movable arm 11. A mounting cover 22 is provided on the upper surface of the movable arm 11. A pressure sensor 15 is connected to the inner bottom wall of the mounting cover 22. A limit block 20 is fixedly connected to the upper end of the detection pin 12, and the limit block 20 is used to restrict the downward movement of the detection pin 12. The limit block 20 can slide freely up and down inside the mounting cover 22. The pressing block 18 is engaged inside the mounting cover 22 and slides freely up and down inside the mounting cover 22. The return spring 19 is vertically installed inside the mounting cover 22. The two ends of the return spring 19 in the direction of elastic force respectively elastically abut against the pressing block 18 and the limit block 20 at the upper end of the detection pin 12. The upper surface of the pressing block 18 abuts against the pressure sensor 15. The lower end of the detection pin 12 is rotatably fitted with a ball 21.

[0032] The return spring 19 generates an upward elastic resisting force on the extrusion block 18, causing the upper end face of the extrusion block 18 to abut against the surface of the pressure sensor 15. This causes the pressure sensor 15 to generate a pressure signal, which is then fed back to the external controller device. Based on the changes in the pressure signal fed back by the pressure sensor 15, the flatness of the tile surface can be detected more accurately. A short pin 17 is fixed to the outer wall of the extrusion block 18, and the mounting cover 22 has an oblong hole 16 for the short pin 17 to be inserted. This prevents the extrusion block 18 from rotating, avoiding detection errors caused by different contact positions between the surface of the extrusion block 18 and the surface of the pressure sensor 15. In addition, the upper surface of the moving arm 11 is vertically fixed. A sliding pin 13 is connected to a fixed plate 6 coaxially fixed to the movable seat 8. The end face of the fixed plate 6 has a spiral groove 7. The upper end of the sliding pin 13 is inserted into the spiral groove 7. When the output shaft of the motor 2 rotates, it will drive the connecting shaft 5 to rotate. The rotation of the connecting shaft 5 will drive the rotating shaft 9 to rotate. When the rotating shaft 9 rotates, it will drive the mounting part 10 and the moving arm 11 to rotate. In addition, when the moving arm 11 rotates, the sliding pin 13 will move along the spiral trajectory in the spiral groove 7. In this way, the moving arm 11 can also move in the horizontal direction while rotating, so that the movement trajectory of the ball 21 on the surface of the tile is spiral, which maximizes the detection range.

[0033] The working principle of this utility model is as follows: The mobile vehicle 1 is moved to the tile laying surface, and then the lifting cylinder 4 is activated. The cylinder rod of the lifting cylinder 4 extends, thereby driving the movable seat 8 to move downward. When moving downward, the ball bearing 21 installed at the bottom of the detection pin 12 will contact the tile surface, and at this time the detection pin 12 will move upward, thereby causing the limit block 20 to squeeze the reset spring 19. The reset spring 19 generates an upward elastic resisting force on the squeezing block 18, causing the squeezing block 18 to generate a squeezing force on the pressure sensor 15, thereby causing the pressure sensor 15 to generate a pressure signal. At this time, the controller device collects the pressure signal and sets the data to zero.

[0034] When motor 2 is restarted, the output shaft of motor 2 rotates, which in turn drives the connecting shaft 5 to rotate. Since the spline hole on the connecting shaft 5 and the rotating shaft 9 is keyed, the rotating shaft 9 can be driven to rotate. When the rotating shaft 9 rotates, it will drive the mounting part 10 and the moving arm 11 to rotate. In addition, when the moving arm 11 rotates, the sliding pin 13 will move along the spiral trajectory in the spiral groove 7. In this way, the moving arm 11 can also move in the horizontal direction while rotating, so that the movement trajectory of the ball 21 on the surface of the tile is spiral.

[0035] When the ball bearing 21 rolls on the surface of the tile, if the surface is uneven, the detection pin 12 will move upward when the ball bearing 21 rolls to a convex position due to the elastic resistance of the return spring 19. This increases the elastic resistance of the return spring 19 against the pressing block 18, resulting in a larger data feedback from the pressure sensor 15 to the controller. Conversely, when the ball bearing 21 rolls to a concave position, the elastic potential energy of the return spring 19 is released, driving the limit block 20 to move downward, causing the detection pin 12 to move downward. At this time, the elastic resistance of the return spring 19 against the pressing block 18 decreases, resulting in a smaller data feedback from the pressure sensor 15 to the controller. Thus, by collecting data from the pressure sensor 15 in real time through the controller, a more accurate and realistic detection result of the tile surface flatness can be obtained. In addition, the connection between the pressure sensor 15 and the controller (such as a microcontroller) is existing technology and will not be described in detail here.
