Description

Technical Field

[0001] The utility model belongs to the technical field of flatness detection, and particularly relates to a flatness detector capable of automatically leveling an engineering supervision project. Background Art

[0002] The flatness detector used in engineering supervision is an instrument specially used to measure and evaluate the flatness of the ground, road surface or other engineering surfaces. This detector is usually equipped with a high-precision sensor and a data processing system, which can quickly and accurately obtain the surface flatness data. At present, in the process of engineering supervision, it is usually necessary to detect the flatness of the ground. For example, the Chinese patent with the publication number "CN220665898U" discloses a road surface flatness meter for engineering supervision, which includes a bottom plate, support rods are arranged around the bottom of the bottom plate, a detector is arranged on the top of the bottom plate, a mounting plate is arranged on the top left side of the bottom plate, and the mounting plate is arranged on the bottom of the bottom plate. Low-speed motors are provided on the front and rear end surfaces of the top; a mounting plate is provided on the left side of the bottom plate, and low-speed motors are provided on the front and rear end surfaces of the top mounting plate. The low-speed motor can drive the disc to rotate through the motor shaft, and when the disc rotates, it will drive the cleaning bristles provided at the bottom to rotate, and when the cleaning bristles rotate with the rotation of the disc, the road surface can be cleaned. In this way, the road surface on which the entire device is about to travel can be fully cleaned by rotating the disc and the cleaning bristles at the same time. Even when there are obstacles such as stones on both sides of the road, they can be cleaned in time to avoid affecting the movement of the device.

[0003] During the use of the above device, although a cleaning device is used to assist in cleaning, which improves the detection accuracy, during its specific application, the flatness detector on the top is in a fixed state. When the device is tilted, the entire flatness detector will tilt, because the flatness detector needs to ensure its own stability and accuracy during measurement to avoid measurement errors caused by the instability of the equipment itself. Adjusting the flatness detector to a horizontal state helps to ensure the accuracy and reliability of the measurement results. If the detector is not in a horizontal state, it may cause deviations in the measurement data, thereby affecting the accurate assessment of the road surface flatness. It can be seen that the existing equipment has certain defects and shortcomings. Utility Model Content

[0004] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a flatness detector which can automatically adjust the level for engineering supervision, so as to solve the problems raised by the background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A flatness detector for engineering supervision that can be automatically leveled comprises a bottom frame, support legs are fixedly installed at the four corners of the top of the bottom frame, a support frame is fixedly installed on the top of the support legs, a leveling mechanism is fixedly installed on the top of the support frame, a detector body is fixedly installed on the bottom of the leveling mechanism, a base frame is fixedly installed on both ends of the front and rear sides of the bottom frame, the inner side of the base frame is rotatably connected with walking wheels, a cleaning mechanism is fixedly installed on the bottom of the bottom frame, and the cleaning mechanism is arranged on the outside of the leveling mechanism;

[0007] The leveling mechanism includes a circular groove and a limit assembly. The circular groove is opened in the middle of the top of the support frame. The internal rotation of the circular groove is connected with a mounting ball. The bottom of the mounting ball is fixedly connected to the top of the detector body. The limit assembly is fixedly installed on the top of the support frame. The bottom frame firmly supports the support frame through the supporting legs. The leveling mechanism installed on the support frame can ensure that the detector body always remains in a horizontal state when in use. No matter how the ground is tilted, the design of the leveling mechanism is particularly ingenious. By fixing the mounting ball and the detector body and utilizing the hinged characteristics of the mounting ball, the detector body can adapt to the ground. The angle can be adjusted to achieve automatic leveling. This design greatly improves the detection accuracy and reduces the error caused by uneven ground. In addition, the setting of the cleaning mechanism further enhances the practicability of the device. Through the operation of the driving motor, the cleaning brush can slide horizontally to effectively remove the stone garbage on the ground and ensure the smooth progress of the detection process. This automatic cleaning function not only improves work efficiency, but also reduces the trouble of manual cleaning. At the same time, the device also has flexible detection capabilities. The cleaning brushes are located on both sides of the detector body, so that detection can be carried out whether the device is pushed or dragged, which greatly improves the convenience of detection.

[0008] As a preferred technical solution, the limit assembly includes a concave frame, which is fixedly installed on the top of the support frame. An electric push rod is fixedly installed on the top of the concave frame, and the bottom output end of the electric push rod passes through the concave frame. The limit assembly is mainly composed of the concave frame and the electric push rod. The concave frame is firmly fixed on the top of the support frame, providing an installation basis for the electric push rod. As a common power drive element, the bottom output end of the electric push rod can pass through the concave frame to be connected with other parts of the leveling mechanism. During the use of the device, when it is necessary to fix the detector body or keep it stationary, the electric push rod will start and run, and the bottom output end of the electric push rod will push the part connected to it, causing the limit suction cup to move downward so that it contacts the top of the mounting sphere, thereby fixing the mounting sphere.

[0009] As an optimal technical solution, the bottom output end of the electric push rod passes through the concave frame and is fixedly installed with a limit suction cup. The inner side of the limit suction cup is set in an arc shape. After the bottom output end of the electric push rod passes through the concave frame, a limit suction cup is fixedly installed. The design of this limit suction cup is very clever, and its inner side is set in an arc shape. This shape matches the top of the mounting sphere, ensuring that it can fit tightly when in contact and provide stable supporting force. When the electric push rod starts and pushes the limit suction cup to move downward, the limit suction cup will fit tightly on the top of the mounting sphere, and the mounting sphere and its bottom detector body are fixed by the adsorption force of the suction cup and the tightness of the fit.

[0010] As a preferred technical solution, a handrail rod is fixedly installed on one side of the top of the support frame, and a handrail frame is fixedly installed on the outer end of the handrail rod. The presence of the handrail rod and the handrail frame provides great convenience and comfort for the user. The handrail rod is firmly fixed on one side of the top of the support frame, and its position is carefully considered to ensure that the user can conveniently hold it when operating the device, and the handrail frame is fixedly installed on the outer end of the handrail rod. The design of the handrail frame takes ergonomics into consideration, and its shape and material are intended to provide a comfortable holding experience. When the user pushes or operates the flatness tester, the user can stabilize and control the device by holding the handrail frame, which not only helps to reduce the labor intensity of the user, but also improves the accuracy and stability of the operation.

[0011] As a preferred technical solution, the top-view shape of the armrest is concave, and the outer surface of the armrest is fixedly installed with an anti-slip armrest cover. The top-view shape of the armrest is concave. This design makes the armrest more ergonomic visually, and also provides a more fitting support for the user's hands. The concave structure can naturally adapt to the shape of the hand, so that the user can feel more comfortable and stable support when holding the armrest. In addition, the outer surface of the armrest is also fixedly installed with an anti-slip armrest cover. This anti-slip armrest cover is made of anti-slip material and has a certain friction coefficient on the surface, which can effectively prevent the user's hands from slipping during use, especially in a wet or greasy environment. The anti-slip armrest cover can exert its excellent anti-slip performance.

[0012] As an optimal technical solution, the cleaning mechanism includes a bottom rail, which is fixedly installed on both sides of the bottom of the bottom frame, and a driving assembly is fixedly installed on one side of the bottom rail. A screw rod is rotatably connected to the inside of the bottom rail, and a slider is threadedly connected to the outer surface of the screw rod. A cleaning brush is fixedly installed on the bottom of the slider, and the outer end of the screw rod is fixedly connected to the driving assembly, and the screw rod is rotatably connected to the inside of the bottom rail. The outer surface of the screw rod is threadedly connected to the slider. This connection method enables the slider to slide along the screw rod inside the bottom rail when the screw rod rotates, and a cleaning brush is fixedly installed on the bottom of the slider. The cleaning brush is made of wear-resistant and durable material, which can effectively remove obstacles on the ground and improve detection accuracy.

[0013] As a preferred technical solution, the driving assembly includes a side frame, the side frame is fixedly installed on one side of the bottom rail, both ends of the outer side of the side frame are rotatably connected with a transmission pulley, the transmission pulleys are connected by a transmission belt, the transmission pulley and the outer end of the screw rod are fixedly connected, a fixed frame is fixedly installed on the outer side of the side frame, a driving motor is fixedly installed on the outer side of the fixed frame, the output end of the driving motor is fixedly connected to the outer side of a transmission pulley, the driving assembly is fixed to one side of the bottom rail through the side frame, providing a stable support structure for the entire driving system, the two ends of the outer side of the side frame are respectively rotatably connected with the transmission pulleys, and the two transmission pulleys are connected by a transmission belt to ensure effective transmission of power and achieve stable transmission.

[0014] In summary, the utility model mainly has the following beneficial effects:

[0015] First, by setting a leveling mechanism, the device uses a mounting sphere to realize an automatic leveling function. The mounting sphere assists in hinged mounting of the detector body, and its center of gravity remains horizontal and vertical to the ground. When the ground is tilted, due to the constancy of the gravity of the center of the earth, the mounting sphere and the detector body at its bottom can rotate adaptively to ensure that the detector body always remains horizontal. During the detection process, if it is necessary to fix or keep it still, the electric push rod can be started to push the limit suction cup to contact the top of the mounting sphere, thereby stabilizing the device and fixing the detector body. This design enables the device to flexibly adapt to the detection needs of different working conditions, and improves the adaptability and detection accuracy;

[0016] Second, by setting up a cleaning mechanism, the device realizes an automatic cleaning function. After the driving motor is started, the two sets of drive pulleys connected by the transmission belt rotate synchronously, thereby driving the two sets of screw rods to rotate, so that the slider slides in the bottom rail. This sliding action drives the cleaning brushes located on both sides of the detector body to move horizontally, effectively sweeping away the stone garbage on the ground. This horizontal sweeping design is not only efficient, but also improves the cleaning effect. At the same time, the design of the cleaning brushes on both sides enables the device to be detected when pushed or dragged, enhancing the convenience of detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The leveling mechanism 5 includes a circular groove 51 and a limit assembly 52. ​​The circular groove 51 is opened in the middle of the top of the support frame 3. The internal rotation of the circular groove 51 is connected with a mounting ball 53. The bottom of the mounting ball 53 is fixedly connected to the top of the detector body 6. The limit assembly 52 is fixedly installed on the top of the support frame 3. The bottom frame 1 firmly supports the support frame 3 through the support legs 2, and the leveling mechanism 5 installed on the support frame 3 can ensure that the detector body 6 always remains in a horizontal state when in use. No matter how the ground is tilted, the design of the leveling mechanism 5 is particularly ingenious. By fixing the mounting ball 53 and the detector body 6 and utilizing the hinged characteristics of the mounting ball 53, the detector body 6 can adjust the angle adaptively to achieve automatic leveling. This design greatly improves the detection accuracy and reduces the error caused by uneven ground. In addition, the setting of the cleaning mechanism 8 further enhances the practicability of the device. Through the operation of the driving motor 824, the cleaning brush 85 can slide horizontally to effectively sweep away the stone garbage on the ground to ensure the smooth progress of the detection process. This automatic cleaning function not only improves the work efficiency, but also reduces the trouble of manual cleaning. At the same time, the device also has flexible detection capabilities. The cleaning brushes 85 are located on both sides of the detector body 6, so that detection can be carried out whether the device is pushed or dragged, which greatly improves the convenience of detection.

An electric push rod 522 is fixedly mounted on the top of the concave frame 521. The bottom output end of the electric push rod 522 passes through the concave frame 521. The limiting assembly 52 is mainly composed of the concave frame 521 and the electric push rod 522. The concave frame 521 is firmly fixed on the top of the support frame 3, providing an installation basis for the electric push rod 522. As a common power drive element, the bottom output end of the electric push rod 522 can pass through the concave frame 521, so as to be connected with other parts of the leveling mechanism 5. During use, when the detector body 6 needs to be fixed or kept stationary, the electric push rod 522 will start and run, and the bottom output end of the electric push rod 522 will push the part connected to it, causing the limiting suction cup 523 to move downward so that it contacts the top of the mounting sphere 53, thereby fixing the mounting sphere 53 and positioning the detector body 6. Through this design, the limiting assembly 52 can provide additional stability and fixation when needed, ensuring that the detector body 6 remains horizontal during the detection process, which not only helps to improve the detection accuracy, but also enables the device to adapt to more different working conditions and environmental conditions.

After the bottom output end of the electric push rod 522 passes through the concave frame 521, a limit suction cup 523 is fixedly installed. The design of this limit suction cup 523 is very clever, and its inner side is set in an arc shape. This shape fits the top of the mounting sphere 53 to ensure that it can fit tightly when in contact and provide stable supporting force. When the electric push rod 522 is started and pushes the limit suction cup 523 to move downward, the limit suction cup 523 will fit tightly on the mounting sphere The top of the body 53 is fixed to the mounting sphere 53 and the detector body 6 at its bottom by the adsorption force and tightness of the suction cup. This fixing method is not only stable and reliable, but also simple and convenient to operate, and can quickly fix and release the detector body 6. At the same time, since the inner side of the limiting suction cup 523 is arranged in an arc shape, it also has a certain adaptive adjustment ability. Even if the mounting sphere 53 has a slight position deviation or tilt during the installation process, the limiting suction cup 523 can also perform adaptive adjustment through its arc-shaped internal structure to ensure a close fit with the top of the mounting sphere 53 to achieve effective fixation.

The handrail frame 10 is fixedly installed on the outer end of the handrail 9. The design of the handrail frame 10 takes ergonomics into consideration, and its shape and material are intended to provide a comfortable holding experience. When the user pushes or operates the flatness detector, Holding the handrail 10 to stabilize and control the device not only helps to reduce the labor intensity of the user, but also improves the accuracy and stability of the operation. Especially on uneven ground or in complex environments, the presence of the handrail 9 and the handrail 10 enables the user to control the moving direction and speed of the device more easily. In addition, the design of the handrail 9 and the handrail 10 also enhances the overall stability and safety of the device. When the user needs to temporarily leave the device or perform other operations, the handrail 9 and the handrail 10 can be used to stably park the device in a designated position to prevent it from sliding or tipping over.

[0028] refer to Figure 1-Figure 4The top view shape of the handrail frame 10 is concave, and the outer surface of the handrail frame 10 is fixedly installed with an anti-skid handrail cover. The top view shape of the handrail frame 10 is concave. This design makes the handrail frame 10 more ergonomic visually, and also provides a more fitting support for the user's hand. The concave structure can naturally adapt to the shape of the hand, so that the user can feel more comfortable and stable support when holding the handrail frame 10.

A cleaning brush 85 is fixedly mounted on the bottom of the slider 84. The outer end of the screw rod 83 is fixedly connected to the driving assembly 82, and the screw rod 83 is rotatably connected to the inside of the bottom rail 81. The outer surface of the screw rod 83 is threadedly connected to the slider 84. This connection method enables the slider 84 to slide along the screw rod 83 inside the bottom rail 81 when the screw rod 83 rotates. A cleaning brush 85 is fixedly mounted on the bottom of the slider 84, and the cleaning brush 85 is made of wear-resistant and durable The cleaning brush 85 is made of a material and can effectively remove obstacles on the ground. When working, the driving component 82 starts and drives the screw rod 83 to rotate.

The design of the cleaning brush 85 can effectively remove obstacles such as stones and garbage on the ground to ensure the flatness of the ground during the detection process. The design of this cleaning mechanism 8 not only improves the detection efficiency, but also greatly reduces the burden of manual cleaning. At the same time, since the cleaning brush 85 is located on both sides of the detector body 6, the cleaning mechanism 8 can work normally regardless of pushing or dragging the device for detection, making the detection process more flexible and convenient.

[0030] refer to Figure 1-Figure 4The driving assembly 82 includes a side frame 821, which is fixedly installed on one side of the bottom rail 81. Both ends of the outer side of the side frame 821 are rotatably connected with a transmission pulley 822. The transmission pulleys 822 are connected to each other through a transmission belt 825. The transmission pulley 822 is fixedly connected to the outer end of the screw rod 83. A fixed frame 823 is fixedly installed on the outer side of the side frame 821. A driving motor 824 is fixedly installed on the outer side of the fixed frame 823. The output end of the driving motor 824 is fixedly connected to the outer side of a transmission pulley 822. The drive assembly 82 is fixed to one side of the bottom rail 81 through the side frame 821, providing a stable support structure for the entire drive system. The two ends of the outer side of the side frame 821 are respectively connected to the drive pulleys 822, and the two drive pulleys 822 are connected by a drive belt 825 to ensure the effective transmission of power. The drive pulley 822 and the outer end of the screw rod 83 are fixedly connected. When the drive motor 824 is running, its output end will drive a drive pulley 822 to rotate. 825 is connected, so the other transmission pulley 822 will also rotate synchronously.

[0031] Principle and advantages of use: By setting the leveling mechanism 5, during the use of the device, the detection instrument body 6 is assisted by the installation ball 53 to be hingedly installed. The center of gravity of the detection instrument body 6 and the installation ball 53 is set to be in a state of being horizontal and vertical to the ground. When the ground is tilted, since the center of gravity of the earth's center should not change, gravity can adaptively adjust the installation ball 53 and the rotation of the detection instrument body 6 installed at the bottom thereof. It can be seen that no matter what kind of tilt state the ground is in, the detection instrument body 6 can be automatically leveled, which can maximize the detection accuracy of the device. When leveling is not required or it needs to remain stationary during the detection process, the electric push rod 522 can be started to run, and the electric push rod 522 can push the limit suction cup 523 to contact the top of the installation ball 53, thereby fixing the top of the limit suction cup 523, which can make the device in a relatively stable state, assist in fixing the detection instrument body 6, so that the device can flexibly meet the detection of different working conditions, which can maximize the adaptability and maintain the detection accuracy.

[0032] By setting the cleaning mechanism 8, the device can be operated by starting the driving motor 824 during use, and the driving motor 824 is used to drive a transmission pulley 822 to rotate. The two sets of transmission pulleys 822 are connected by a transmission belt transmission, which can cause the two sets of transmission pulleys 822 to rotate. The rotation of the two sets of transmission pulleys 822 can synchronously drive the two sets of screw rods 83 to rotate. The rotation of the two sets of screw rods 83 can synchronously drive the slider 84 to slide inside the bottom rail 81. The sliding of the slider 84 can assist in adjusting the driving cleaning brush 85 to be horizontally active, and the cleaning brush 85 is located on both sides of the detector body 6. As the cleaning brush 85 slides horizontally, the stone garbage on the ground can be swept away, so that the device can have the function of automatic cleaning. Moreover, since it adopts a horizontal sweeping design, it can clean and sweep more efficiently, which can improve the overall cleaning effect of the device. The design that both sides can be cleaned makes it possible to perform detection regardless of whether the device is pushed or dragged, which can improve the overall detection convenience of the device.
