Description

Technical Field

[0001] The present invention relates to the field of detection devices, and particularly to a planar detection device for municipal engineering. Background Art

[0002] Municipal engineering generally belongs to the national infrastructure construction, referring to the construction of various public transportation facilities, water supply, drainage, gas, urban flood control, environmental sanitation and lighting and other infrastructure in urban construction. It is an essential material basis for the survival and development of cities and a basic condition for improving people's living standards. When performing planar detection in municipal engineering, a specific monitoring device is generally used to detect the flatness of the ground.

[0003] Although the existing planar detection devices for municipal engineering can monitor the flatness of general ground, there are deficiencies in adjusting the distance between the device and the ground. As a result, when performing planar detection, the device may not fit closely with the ground, leading to significant discrepancies in the detection data. Moreover, the existing planar detection devices for municipal engineering do not intuitively reflect the detection effect, and it is impossible to directly observe the flatness of the plane or whether there is an inclination after detection. Therefore, a planar detection device for municipal engineering is proposed. Summary of the Invention

[0004] In view of the above problems, the present invention provides a planar detection device for municipal engineering, which has the advantage of adjusting the flatness between the device and the ground.

[0005] The technical solution of the present invention is as follows: A planar detection device for municipal engineering, including a support frame, a load-bearing plate is welded to the top end of the support frame, two sets of motor groups are provided at the top end of the load-bearing plate, four motors are respectively provided inside the two sets of motor groups, and the motors are signal-connected to a control panel; the output end of the motor group is connected to a first threaded rod, an installation block is sleeved outside the first threaded rod, and four through holes are opened inside the installation block; the first threaded rod is placed inside the through holes; a second guide groove is opened at the top end of the installation block, and the second guide groove is slidably connected to a main positioning plate, and the main positioning plate is fixedly connected to the support frame; two guide blocks are welded to both sides of the installation block, a secondary positioning plate is slidably connected inside the guide blocks, and the secondary positioning plate is fixedly connected to the support frame; by controlling the four independent motors inside the motor group to start simultaneously through the control panel, the installation plate is lowered as required, so that the grounding column is closely attached to the ground; when the operator issues an instruction through the control panel 2, the four motors inside the motor group 3 start simultaneously; the output end of the motor group 3 is connected to the first threaded rod 6, and the rotation of the motor is transmitted to the first threaded rod 6 through the transmission system to make it start to rotate; the rotation of the first threaded rod 6 is the power source for the entire distance adjustment process.

[0006] In a further technical solution, one end of the mounting block is sleeved with a positioning box. A handle is provided at the top of the positioning box. A worm is welded to the bottom of the handle. A first pressing plate is welded to the bottom of the worm. A slot is opened at the top of the positioning box, and a gasket is installed at the top of the slot. The worm passes through the gasket. The worm is meshed with a worm gear. Two groups of second threaded rods are welded to both sides of the worm gear. Both ends of the second threaded rod are placed inside the positioning box. With this structural design, the rotation of the handle is used to control the rotation of the worm, and at the same time, the downward rotation movement of the worm drives the rotation of the worm gear and the second threaded rod.

[0007] In a further technical solution, two groups of second sliding blocks are threadedly connected to the outside of the second threaded rod. A second pressing plate is welded to the bottom of the second sliding block. A main board slot is opened at the center of the positioning box, and a main positioning plate is slidably connected inside the main board slot. Auxiliary board slots are opened on both sides of the positioning box, and auxiliary positioning plates are slidably connected inside the auxiliary board slots. The thread patterns inside the two groups of second sliding blocks are opposite. By turning the handle, the first pressing plate is simultaneously pressed down against the main positioning plate, and the auxiliary positioning plates are pressed by the reverse movement of the second sliding blocks with opposite internal threads, thereby realizing the positioning operation.

[0008] In a further technical solution, four groups of springs are welded to the bottom of the perforation. The other ends of the springs are welded to a pressing plate. The first threaded rod is placed inside. A threaded hole is opened inside the pressing plate, and the threaded hole is threadedly connected to the first threaded rod. With this structural design, the position of the grounding post is restricted by the constraint of the spring to prevent the pressing plate from falling off, and a certain buffering effect is achieved by setting the spring, thereby protecting the device and prolonging the service life of the device.

[0009] In a further technical solution, the first threaded rod passes through the threaded hole and is connected to the first sliding block. The first sliding block is slidably connected to the first guiding groove, and the first guiding groove is welded to the support frame. With this structural design, the stability of the device operation is improved, and the pressing plate is driven to descend or ascend through this design.

[0010] In a further technical solution, an L-shaped bracket is welded to the bottom of the pressing plate. A reflecting mirror is fixedly connected to the corner of the L-shaped bracket. The included angle between the reflecting mirror and the L-shaped bracket is 45°. A positioning hole is opened at the bottom of the pressing plate, and a laser lamp is fixedly installed inside the positioning hole. The two groups of L-shaped brackets face each other. With this structural design, it can be judged whether the ground is flat by whether the light rays reflected by the two laser lamps are on the same straight line; a reflecting mirror is fixedly connected to the corner of the L-shaped bracket; the included angle between the reflecting mirror and the L-shaped bracket is 45°; at the same time, a laser lamp is fixedly installed inside the positioning hole opened at the bottom of the pressing plate; the two groups of L-shaped brackets face each other, thus forming a symmetric laser detection system.

[0011] In a further technical solution, a grounding post is welded to the bottom of the pressing plate. The bottom of the grounding post passes through the first guiding groove and is placed at the bottom of the support frame. Four groups of rollers are provided at the four corners of the bottom of the support frame. Such a structural design increases the mobility of the device and optimizes the handling efficiency and stability of the device.

[0012] The beneficial effects of the present invention are as follows: 1. The new device optimizes the deficiency of the existing device in adjusting the distance between the device and the ground. It can accurately adjust the distance between the two, make the device closely fit the ground, and effectively avoid the problem of large deviation of detection data caused by insufficient tightness, thereby significantly improving the accuracy and reliability of detection data. The device can be adjusted according to the detection requirements. Through the setting of the adjusting rod, the distance between the device and the ground can be adjusted, so as to adjust the flatness of the ground by the device. 2. Different from the defect that the detection effect of the existing device is not intuitive enough, the new device has an innovative design that the two grounding posts descend to press the ground to lift the device, causing a position deviation in the light rays of the two laser lights. It can display the detection results in a more intuitive way. After the detection, the operator can directly and clearly see the flatness of the ground and whether there is an inclination situation, without complex analysis and interpretation, greatly improving the work efficiency and the accuracy of judgment.

The load-bearing plate 15 is welded to the top of the support frame 1 to carry important components such as the motor group 3. Multiple motors are provided inside the motor group 3 and are signal-connected and controlled through the control panel 2. The first threaded rod 6 is connected to the output end of the motor group 3 and plays a key role in the height adjustment of the device. The installation block 17 is sleeved outside the first threaded rod 6 and cooperates with the first threaded rod 6 through the through holes 22 and is connected to components such as the main positioning plate 16 and the secondary positioning plate 9 to achieve the positioning and movement of the device.

[0017] Four sets of springs 18 are welded to the bottom of the perforation 22, and the other ends of the springs 18 are welded to the pressing plate 10; the first threaded rod 6 is placed inside 24; a threaded hole 26 is formed inside the pressing plate 10, and the threaded hole 26 is threadedly connected to the first threaded rod 6; the first threaded rod 6 passes through the threaded hole 26 and is connected to the first slider 7, and the first slider 7 is slidably connected to the first guiding groove 8, and the first guiding groove 8 is welded to the support frame 1; an L-shaped bracket 11 is welded to the bottom of the pressing plate 10, and a reflecting mirror 12 is fixedly connected to the corner of the L-shaped bracket 11, and the included angle between the reflecting mirror 12 and the L-shaped bracket 11 is 45°; a positioning hole is formed in the bottom of the pressing plate 10, and a laser lamp 13 is fixedly installed inside the positioning hole; the two L-shaped brackets 11 face each other; a grounding post 14 is welded to the bottom of the pressing plate 10, and the bottom of the grounding post 14 passes through the first guiding groove 8 and is placed at the bottom of the support frame 1, and four sets of rollers 5 are provided at the four corners of the bottom of the support frame 1.

[0018] The working principle of the above technical solution is as follows: The planar detection device mainly consists of components such as a support frame 1, a load-bearing plate 15, a motor group 3, a first threaded rod 6, a mounting block 17, a positioning box 4, a pressing plate 10, a grounding post 14, a laser lamp 13, and a reflecting mirror 12; the support frame 1 provides a stable support structure as the basic frame of the device; the load-bearing plate 15 is welded to the top of the support frame 1 for carrying important components such as the motor group 3; multiple motors are provided inside the motor group 3 and are signal-connected and controlled through the control panel 2; the first threaded rod 6 is connected to the output end of the motor group 3 and plays a key role in the height adjustment of the device; the mounting block 17 is sleeved outside the first threaded rod 6 and cooperates with the first threaded rod 6 through the perforation 22 and is interconnected with components such as the main positioning plate 16 and the secondary positioning plate 9 to achieve the positioning and movement of the device; the positioning box 4 is used to precisely fix the main positioning plate 16 and the secondary positioning plate 9; the pressing plate 10 is connected to the mounting block 17 through the spring 18, and detection components such as a grounding post 14, a laser lamp 13, and a reflecting mirror 12 are installed at the bottom; the height adjustment of the device mainly relies on the drive of the motor group 3; When an operator issues an instruction through the control panel 2, the four motors in the motor group 3 start simultaneously; the output end of the motor group 3 is connected to the first threaded rod 6, and the rotation of the motor is transmitted to the first threaded rod 6 through the transmission system to make it start rotating; the rotation of the first threaded rod 6 is the power source for the entire spacing adjustment process; an installation block 17 is sleeved outside the first threaded rod 6, and four through holes 22 are opened inside the installation block 17, and the first threaded rod 6 is placed inside the through holes 22; when the first threaded rod 6 rotates, due to the threaded connection between the installation block 17 and the first threaded rod 6, according to the principle of screw drive, the installation block 17 will move up and down along the axial direction of the first threaded rod 6; at the same time, a second guiding groove 23 is opened at the top end of the installation block 17, and the second guiding groove 23 is slidably connected to the main positioning plate 16, and the main positioning plate 16 is fixedly connected to the support frame 1, which provides precise guidance for the movement of the installation block 17 to ensure that it will not deviate or shake during the movement; four springs 18 are welded at the bottom of the through holes 22 of the installation block 17, and the other ends of the springs 18 are welded to the pressing plate 10; when the installation block 17 moves up and down, it will drive the springs 18 and the pressing plate 10 to move synchronously; the existence of the springs 18 plays two important roles: one is that during the descent of the device, when the pressing plate 10 touches the ground, the springs 18 can provide a certain buffer to avoid the hard collision between the pressing plate 10 and the ground and protect the structure and detection components of the device; the other is the elastic force of the springs 18, which can keep the pressing plate 10 in close contact with the ground at all times to ensure the accuracy of the detection data; by controlling the rotation direction and speed of the motor group 3 through the control panel 2, the descent height of the installation block 17 can be accurately adjusted, so as to realize the precise adjustment of the spacing between the device and the ground; when the device descends to the appropriate position, the grounding post 14 on the pressing plate 10 is in close contact with the ground, and at this time, the elastic force generated by the compression of the springs 18 makes the pressing plate 10 in close contact with the ground, effectively avoiding the problem of detection data deviation caused by insufficient close contact; an L-shaped bracket 11 is welded at the bottom of the pressing plate 10; a reflecting mirror 12 is fixedly connected to the corner of the L-shaped bracket 11; the included angle between the reflecting mirror 12 and the L-shaped bracket 11 is 45°; at the same time, a positioning hole is opened at the bottom of the pressing plate 10, and a laser lamp 13 is fixedly installed inside the positioning hole; the two L-shaped brackets 11 face each other, thus forming a symmetrical laser detection system; when the device is placed on the ground to be detected, the laser lamp 13 is started through the control panel 2; the light emitted by the laser lamp 13 irradiates on the ground and then is reflected back by the ground; the reflected light will propagate along a specific path after being reflected by the reflecting mirror 12; if the ground is flat, then the light reflected by the two laser lamps 13 will be on the same horizontal line after being reflected by the reflecting mirror 12, and the operator can intuitively judge whether the ground is flat by observing the position relationship of the light; however, if the ground is inclined or uneven, then there will be a position deviation in the light reflected by the two laser lamps 13 after being reflected by the reflecting mirror 12;Specifically, when the ground on one side is higher, the light reflected by the laser lamp 13 on that side will be at a higher position after being reflected by the reflector 12 than the light on the other side; conversely, when the ground on one side is lower, the position of the light on that side will be lower; the operator can quickly and accurately judge the inclination direction and degree of the ground according to the deviation of the light; this design of judging the flatness and inclination of the ground through the positional relationship of the reflected light of the two groups of laser lamps 13 makes the detection result very intuitive; the operator does not need to perform complex data analysis and calculation, and only needs to directly observe the position of the light to draw a conclusion, which greatly improves the work efficiency and the accuracy of judgment.

[0019] The main positioning plate 16 and the secondary positioning plate 9 in the device play a key role in the positioning and fixing process; the main positioning plate 16 is fixedly connected to the support frame 1, and the second guiding groove 23 of the mounting block 17 is slidably connected to the main positioning plate 16, which provides a guiding and positioning reference for the movement of the mounting block 17; the secondary positioning plate 9 is also fixedly connected to the support frame 1, and the guiding blocks 19 on both sides of the mounting block 17 are slidably connected to the secondary positioning plate 9, further enhancing the stability and positioning accuracy of the mounting block 17 during movement; one end of the mounting block 17 is sleeved with a positioning box 4, and a handle 20 is provided at the top of the positioning box 4; when the device needs to be positioned, the operator can rotate the handle 20; a worm 29 is welded to the bottom of the handle 20, the worm 29 passes through the gasket 27 at the top of the positioning box 4 and is meshed with a worm gear 35, and two second threaded rods are welded to both sides of the worm gear 35; both ends of the second threaded rod 31 are placed inside the positioning box 4, and two groups of second sliding blocks 32 are threadedly connected to the outside thereof, and the thread patterns inside the two groups of second sliding blocks 32 are opposite; when the handle 20 is rotated, the worm 29 will rotate accordingly; since the worm 29 is meshed with the worm gear 35, the rotation of the worm gear 35 will drive the second threaded rods 31 welded to both sides, so that the second threaded rods 31 also start to rotate; since the thread patterns inside the two groups of second sliding blocks 32 are opposite, the rotation of the second threaded rods 31 will cause the two groups of second sliding blocks 32 to move in the opposite direction; at the same time, the rotation of the worm 29 will also cause it to move downward and drive the first pressing plate 30 at the bottom to press the main positioning plate 16 downward; and the opposite movement of the two groups of second sliding blocks 32 will cause the second pressing plates 33 at their bottoms to press the secondary positioning plate 9 respectively; in this way, the simultaneous pressing and fixing of the main positioning plate 16 and the secondary positioning plate 9 are realized, thereby ensuring the stability of the device during the detection process.

[0020] The above-described embodiments only represent the specific implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
