Description

Technical Field

[0001] This utility model relates to the field of building quality testing technology, and in particular to a verticality testing device. Background Technology

[0002] Verticality is a directional tolerance requirement that controls the angle between the measured element and the reference element to be 90°. It is categorized into verticality requirements for a given plane, a given direction, and any direction, and is represented by the symbol ⊥. Based on the characteristics of the measured element and the reference element, verticality evaluates the perpendicularity between lines, planes, or a line and a plane. One of the lines or planes serves as the evaluation reference. The line can be the straight portion of the measured sample or its linear trajectory, and the plane can be the planar portion of the measured sample or the plane formed by its trajectory. Verticality is a crucial technical indicator for ensuring wall safety. During construction, the verticality of both columns and walls is a key focus of quality control. During formwork assembly, a dedicated person will check the verticality of the formwork.

[0003] Existing methods for detecting wall verticality mainly use protractors, balances, and other equipment. However, these devices require fixed positioning during use and are not convenient for moving, thus affecting the efficiency of wall verticality detection. Therefore, there is an urgent need for a verticality detection device to solve these problems. Utility Model Content

[0004] To solve the above problems, this utility model provides a verticality detection device, which is achieved through the following technical solution.

[0005] A perpendicularity testing device includes a right-angle testing frame, with two limiting tubes penetrating one side of the right-angle testing frame. A testing rod is penetrating through the limiting tubes. A limiting reflector is fixedly connected to one end of the testing rod, and a sliding seat is fixedly connected to the other end of the testing rod. A pressure sensor is installed inside the sliding seat, and a ball bearing is rotatably connected to the top of the sliding seat. A spring is fixedly connected to the testing rod, and one end of the spring is fixedly connected to the right-angle testing frame. The device also includes an infrared laser rangefinder.

[0006] Furthermore, two symmetrical sliders are fixedly connected inside the limiting tube, and a groove is opened on the outer surface of the detection rod, and the slider slides in the groove.

[0007] Furthermore, the infrared laser rangefinder and the limiting reflector are located on the same straight line.

[0008] Furthermore, the pressure sensor and the infrared laser rangefinder are both electrically connected to the PLC controller via wires.

[0009] Furthermore, a handle is fixedly connected to the right-angle testing frame, and a protective cover is fixedly connected to the handle. The protective cover is made of either rubber or sponge material.

[0010] Furthermore, the bottom of the right-angle detection frame is equipped with casters.

[0011] The beneficial effects of this utility model are that, during operation, the right-angle detection frame can be moved on the ground by hand-held handle. Simultaneously, the right-angle detection frame is easily moved via casters. The moving frame slowly approaches the wall to be inspected, causing the movable detection rod on the frame to contact the wall. At this point, the pressure on the detection rod allows it to move along the limiting tube. During this movement, an infrared laser rangefinder on the other side of the right-angle detection frame detects the distance between the limiting tubes. When the distances detected by the two infrared laser rangefinders are consistent, the wall is vertical; otherwise, the wall is inclined. The structure is reasonable, facilitating device movement and detection, and enabling rapid detection of the wall's verticality. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-3 As shown, the present invention has the following specific embodiments.

[0024] Example:

[0025] A perpendicularity detection device includes a right-angle detection frame 1. Two limiting tubes 4 are connected through one side of the right-angle detection frame 1. A detection rod 5 is connected through the limiting tubes 4. One end of the detection rod 5 is fixedly connected to a limiting reflector plate 51. The other end of the detection rod 5 is fixedly connected to a sliding seat 52. A pressure sensor 522 is installed inside the sliding seat 52. A ball bearing 521 is rotatably connected to the top of the sliding seat 52. A spring 54 is fixedly connected to the detection rod 5. One end of the spring 54 is fixedly connected to the right-angle detection frame 1. The device also includes an infrared laser rangefinder 2.

[0026] Specifically, two symmetrical sliders 41 are fixedly connected inside the limiting tube 4, and a groove 53 is opened on the outer surface of the detection rod 5, and the sliders 41 slide in the groove 53, so that the detection rod 5 can move in the upper limit of the limiting tube 4.

[0027] Specifically, the infrared laser rangefinder 2 and the limiting reflector 51 are located on the same straight line, enabling the infrared laser rangefinder 2 to detect the distance between the limiting reflector 51 and the infrared laser rangefinder 2.

[0028] Specifically, the pressure sensor 522 and the infrared laser rangefinder 2 are both electrically connected to the PLC controller 3 via wires. The pressure sensor 522 can detect the pressure received by the sliding seat 52 pressing against the wall.

[0029] Specifically, a handle 11 is fixedly connected to the right-angle testing frame 1, and a protective cover is fixedly connected to the handle 11. The protective cover is made of either rubber or sponge material. The handle 11 facilitates manual pushing of the right-angle testing frame 1 for movement.

[0030] Specifically, the bottom of the right-angle testing frame 1 is equipped with casters 12, which facilitates the movement of the right-angle testing frame 1.

[0031] The working principle of this utility model:

[0032] When using the device, the right-angle detection frame 1 can be moved on the ground by holding the handle 11. At the same time, the right-angle detection frame 1 is easily moved by the casters 12. The moving right-angle detection frame 1 slowly approaches the wall to be tested, so that the movable detection rod 5 on the right-angle detection frame 1 is in contact with the wall. At this time, the pressure on the detection rod 5 can move on the limit tube 4. During the movement of the detection rod 5, the infrared laser rangefinder 2 set on the other side of the right-angle detection frame 1 can detect the distance between the limit tubes 4. When the distances detected by the two infrared laser rangefinders 2 are consistent, the wall is vertical. Otherwise, the wall is tilted. The structure is reasonable, which facilitates the movement and testing of the device and can quickly detect the verticality of the wall.
