According to the needs, the angle of the overall supporting assembly is adjusted, and the overall device is first leveled. The leveling method is to rotate the telescopic threaded shaft and adjust the length of the telescopic threaded shaft to adjust the angle of the overall horizontal measuring assembly so that the horizontal measuring assembly is maintained in a horizontal state. After the adjustment, the liquid level on the level measuring instrument can be observed to determine whether the horizontal measuring assembly is horizontal. After adjusting the level, the position of the auxiliary positioning mechanism on one side of the angle ruler can be observed. Since the auxiliary positioning mechanism is always located in the vertical direction, the inclination angle on the bearing surface where the overall device is installed can be understood by this method. After the device is leveled, the drive motor can be controlled to start, the drive motor can drive the double threaded shaft to rotate, the double threaded shaft can drive the moving block to move downward, and the auxiliary positioning mechanism can move downward synchronously until the mounting shell contacts the placement surface. At this time, the contact area between the equipment and the placement surface is effectively improved, thereby assisting the overall device in positioning.

During the application process, if there is wind in the environment, the wind can be transmitted through the two sides of the two trapezoidal slides, giving the two trapezoidal slides a certain downward pressure, further ensuring the stability of the device. Through this design, the overall structure is easy to level, and the device can be applied to inclined mounting surfaces of different degrees, and the leveling of the horizontal measurement component can still be achieved without affecting the use of the device.

[0047] The support assembly 4 includes a bracket 43, an installation shaft 41 is fixedly installed inside the bracket 43, and the installation shaft 41 is rotatably installed in a rotating hole set inside the protection box 2. One end of the installation shaft 41 is provided with a thread, and a limiting screw sleeve 42 is threadedly installed on one end of the installation shaft 41. One side of the limiting screw sleeve 42 is in close contact with and squeezed with the side wall of the protection box 2. The internal thread of the bracket 43 is installed with a telescopic threaded shaft 44, and the telescopic threaded shaft 44 is rotatably installed with a base 45 through a rotating shaft.

[0048] The driving assembly 11 includes a double-threaded shaft 111 and a driving motor 112. The driving motor 112 is fixedly mounted on a mounting frame arranged inside the protective box 2. A driving gear 113 is fixedly mounted on one end of the output shaft of the driving motor 112. The double-threaded shaft 111 is rotatably mounted on an axis frame arranged inside the protective box 2.

The driven gear 114 is located above the second side pressure plate 115, and the driving gear 113 and the driven gear 114 are meshed and connected with each other.

[0049] The specific implementation method is as follows: when the device is used, the device is first placed on the bearing surface, and the angle of the overall support component 4 is adjusted as needed. The overall device is first leveled. The leveling method is to rotate the telescopic threaded shaft 44 and adjust the length of the telescopic threaded shaft 44 to adjust the angle of the overall horizontal measurement component 9 so that the horizontal measurement component 9 is maintained in a horizontal state. After adjustment, the liquid level on the level measuring device 91 can be observed to determine whether the horizontal measurement component 9 is horizontal. After adjusting the level, the position of the auxiliary positioning mechanism 8 on one side of the angle ruler 7 can be observed. Since the auxiliary positioning mechanism 8 is always located in the vertical direction, the inclination angle on the bearing surface where the overall device is installed can be understood by this method. After leveling the device, the drive motor 112 can be controlled to start, and the drive motor 112 can drive the double threaded shaft 111 to rotate, and the double threaded shaft 111 can drive the moving block 6 to move downward, and the auxiliary positioning mechanism 8 moves downward synchronously until the mounting shell 83 is aligned with the placement surface. The mounting shell 83 is also rotatable, so the structure can be applied to the inclined mounting surface with the mounting shell 83. After the mounting shell 83 contacts the mounting surface, the positioning head 846 will also be squeezed, and the positioning head 846 can shrink toward the inside of the mounting shell 83. Since the bottom of the positioning head 846 is an arc surface, after the positioning head 846 is pressed in, the sleeve spring 841 can push the two trapezoidal slides 843 that have lost their limit to the side, and the two trapezoidal slides 843 are led out, and the expansion sponge pads on the bottom surface expand rapidly and contact the contact surface, further increasing the contact area between the overall structure and the mounting surface, thereby further improving the positioning effect of the overall structure. In addition, during the application process, if there is wind in the environment, the wind can be transmitted through the two sides of the two trapezoidal slides 843, giving the two trapezoidal slides 843 a certain downward pressure, thereby further ensuring the stability of the device.

[0050] Through this design, the overall structure is easy to level, and the device can be applied to installation surfaces with different degrees of inclination. The leveling of the horizontal measurement component 9 can still be achieved without affecting the use of the device. At the same time, it can assist the device to be quickly positioned without unnecessary operations. It is convenient and effective, and can utilize wind power in a strong wind environment to further enhance the stability of the device and greatly improve the actual application effect of the device.

[0051] The level measuring component 9 includes a mounting seat 93, and the mounting seat 93 is threadedly mounted on the upper end of the double threaded shaft 111 through a threaded hole arranged inside the mounting seat 93. A top groove 92 is arranged on the top surface of the mounting seat 93, and an adsorption magnetic plate is arranged inside the top groove 92. A level measuring device 91 is adsorbed and mounted on the adsorption magnetic plate. Wiping cotton pads are arranged on the inner walls on both sides of the protective box 2.

[0052] The specific implementation method is as follows: after the equipment is leveled, while the auxiliary positioning mechanism 8 is descending, the rotating double-threaded shaft 111 can drive the upper level measuring component 9 to move upward. At this time, the objective lens and eyepiece of the level measuring device 91 can come into contact with the wiping cotton pad, and the objective lens and eyepiece of the level measuring device 91 can be wiped synchronously. After wiping, the level measuring device 91 can automatically open the top cover 1 and run outside the protective box 2. At this time, the auxiliary positioning mechanism 8 also assists in positioning the device, and the level measuring device 91 can be used directly.

[0053] Through this design, the auxiliary positioning of the device and the cleaning and export of the measuring structure can be completed simultaneously, which improves the convenience of using the equipment. Moreover, when not in use, the measuring structure can be well protected, thereby improving the actual application effect of the overall device.

[0054] Lubrication components 10 are provided on the inner walls on both sides of the protection box 2, and the lubrication components 10 are used for stable lubrication of the installation shaft 41. The lubrication components 10 include an oil storage tank 105, and the oil storage tank 105 is fixedly installed on the inner wall of the protection box 2. Two oil replenishing pipes 106 are fixedly installed on the outer wall of one side of the oil storage tank 105, and one end of the two oil replenishing pipes 106 passes through and extends to the outside of the protection box 2. An oil guide ring 104 is fixedly installed on the bottom of the oil storage tank 105 through an oil pipe, and the oil guide ring 104 is sleeved on the outside of the installation shaft 41. An oil pressure plate is provided inside the oil storage tank 105, and two piston rods 102 are fixedly installed on the outer wall of one side of the oil pressure plate, and a first side pressure plate 103 is fixedly installed on one end of the two piston rods 102. A return spring 101 is sleeved on the outside of the piston rod 102, and the first side pressure plate 103 is located on one side of the second side pressure plate 115.

[0055] The specific implementation method is as follows: during the driving rotation of the double-threaded shaft 111, the second side pressure plate 115 can be driven to rotate synchronously. During the rotation, the second side pressure plate 115 can respectively contact and press the first side pressure plates 103 of the lubrication components 10 on both sides. The first side pressure plates 103 that are contacted and pressed can control the displacement of the oil pressure plate, and guide the oil in the oil storage tank 105 to the outside of the mounting shaft 41 through the oil guide ring 104, thereby achieving effective lubrication of the mounting shaft 41 and making the angle adjustment of the support component 4 smoother.

[0056] Through this design, the support assembly 4 can be lubricated during the equipment positioning process, thereby continuously ensuring the smoothness and convenience of the rotation of the support assembly 4 and improving the use effect of the equipment.

[0057] Working principle: When the device is used, the device is first placed on the bearing surface. According to the needs, the angle of the overall support component 4 is adjusted, and the overall device is leveled first. The leveling method is to rotate the telescopic threaded shaft 44 and adjust the length of the telescopic threaded shaft 44 to adjust the angle of the overall horizontal measurement component 9 so that the horizontal measurement component 9 is maintained in a horizontal state. After adjustment, the liquid level on the level measuring device 91 can be observed to determine whether the horizontal measurement component 9 is horizontal. After adjusting the level, the position of the auxiliary positioning mechanism 8 on one side of the angle ruler 7 can be observed. Since the auxiliary positioning mechanism 8 is always located in the vertical direction, the inclination angle on the bearing surface where the overall device is installed can be understood by this method. After leveling the device, the drive motor 112 can be controlled to start, and the drive motor 112 can drive the double threaded shaft 111 to rotate. The double threaded shaft 111 can drive the moving block 6 to move downward, and the auxiliary positioning mechanism 8 moves downward synchronously until the mounting shell 83 contacts the placement surface. At this time, the contact area between the device and the placement surface is effectively improved, thereby assisting the overall device in positioning. Since the mounting shell 83 is also rotatable, the structure can be applied to the inclined placement surface in conjunction with the overall device. After the mounting shell 83 contacts the placement surface, the positioning head 846 will also be squeezed, and the positioning head 846 can shrink toward the inside of the mounting shell 83. Since the bottom of the positioning head 846 is an arc surface, after the positioning head 846 is pressed in, the sleeve spring 841 can push the two trapezoidal slides 843 that have lost their limit to the side, and the two trapezoidal slides 843 are led out, and the expansion sponge pads on the bottom surface expand rapidly and contact the contact surface, further increasing the contact area between the overall structure and the placement surface, thereby further improving the positioning effect of the overall structure. In addition, during the application process, if there is wind in the environment, the wind can be transmitted through the two sides of the two trapezoidal slides 843, giving the two trapezoidal slides 843 a certain downward pressure, further ensuring the stability of the device.

[0058] After the device is leveled, during the descent of the auxiliary positioning mechanism 8, the rotating double-threaded shaft 111 can drive the upper level measuring assembly 9 to move upward, at which time the objective lens and the eyepiece of the level measuring device 91 can come into contact with the wiping cotton pad, and the objective lens and the eyepiece of the level measuring device 91 can be wiped synchronously. After wiping, the level measuring device 91 can automatically open the top cover 1 and move outside the protective box 2. At this time, the auxiliary positioning mechanism 8 also assists in positioning the device, and the level measuring device 91 can be used directly;

[0059] During the driven rotation of the double-threaded shaft 111, the second side pressure plate 115 can be driven to rotate synchronously. During the rotation, the second side pressure plate 115 can respectively contact and press the first side pressure plates 103 of the lubrication components 10 on both sides. The first side pressure plates 103 that are contacted and pressed can control the displacement of the oil pressure plate, and guide the oil in the oil storage tank 105 to the outside of the mounting shaft 41 through the oil guide ring 104, thereby achieving effective lubrication of the mounting shaft 41 and making the angle adjustment of the support component 4 smoother.

[0060] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
