[0002] Infrared laser floor leveling machines, also known as laser leveling instruments, are frequently used on construction sites. These machines emit projected laser beams in the form of points, horizontal lines, vertical lines, or intersecting lines. The laser beams serve as precise visual references to assist in construction, aligning and leveling objects.

[0003] Infrared laser ground leveling inspection machines are usually supported on the ground by a tripod. Since the ground may tilt in various directions, it is necessary to adjust the three support legs of the tripod to level the infrared laser ground leveling inspection machine before use.

[0004] In existing technologies, the tripod of an infrared laser ground leveling inspection machine typically uses sliding or threaded adjustments to adjust the length of its three support legs for leveling. Manual adjustment is inconvenient and lacks precision.

[0005] Therefore, in order to solve the above-mentioned technical problems in the existing technology, an infrared laser ground leveling inspection machine for building engineering is proposed. Summary of the Invention

It features automatic leveling of the laser module via a pendulum, and control of the tripod by adjusting the tilt direction and angle of the pendulum.

[0026] The present invention has the following beneficial effects:

[0027] 1. This construction project utilizes an infrared laser ground leveling machine. The machine employs retractable support legs comprised of fixed and telescopic sections. These three legs form a tripod structure to ensure the laser leveling instrument remains stable, providing a visual reference for the laser beam on the construction site. The telescopic joints are operated by a cylinder consisting of an air reservoir and a piston within the fixed section. By controlling the connection between the three air reservoirs, an air pump can be used to pump a portion of the gas from one reservoir into one or two other reservoirs, controlling the extension and retraction of the three support legs to adjust the laser leveling instrument to a horizontal position on uneven ground.

[0028] 2. The infrared laser ground leveling machine used in this construction project has three support legs positioned at the front and on the left and right sides at 120° intervals. When the laser leveling instrument tilts backward, the air pump and the first proportional valve assembly control the gas in the front air storage chamber to be divided into two portions and injected into the two air storage chambers located on the left and right sides, thereby causing the laser leveling instrument to tilt forward and level itself based on the left and right horizontal axis. When the laser leveling instrument tilts forward, the air pump and the second proportional valve assembly control the two equal portions of gas in the left and right air storage chambers to be injected into the air storage chamber located on the front side, thereby causing the laser leveling instrument to tilt backward and level itself based on the left and right horizontal axis.

[0029] 3. The infrared laser ground leveling machine used in this construction project operates as follows: When the laser leveling instrument tilts to the left, a portion of the gas in the right-side air storage chamber is injected into the left-side air storage chamber via an air pump, causing the laser leveling instrument to flip to the right based on its horizontal axis. Conversely, when the laser leveling instrument tilts to the right, a portion of the gas in the left-side air storage chamber is injected into the right-side air storage chamber via an air pump, causing the laser leveling instrument to flip to the left based on its horizontal axis.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1, please refer to Figures 1-11 An infrared laser ground leveling inspection machine for building engineering includes a laser leveling instrument 100, a support mechanism 200 and an adjustment mechanism 300. The support mechanism 200 includes a support frame 210, three fixed sections 220 are arranged circumferentially on the support frame 210, and telescopic sections 230 are slidably arranged on each of the three fixed sections 220. Pistons 240 are arranged on each of the three telescopic sections 230, and the pistons 240 and the inner cavity of the fixed sections 220 form a retractable air storage cavity 250.

[0045] The adjustment mechanism 300 includes a mounting base 310 disposed on the support frame 210, a laser leveling instrument 100 disposed on the mounting base 310, a turntable 320 rotatably disposed on the mounting base 310, and an air pump 330 disposed on the turntable 320.

[0046] The gas distribution in the three gas storage chambers 250 is controlled by the air pump 330 to control the extension and retraction of the three expansion joints 230, thereby leveling the laser leveling instrument 100.

[0047] Three connecting seats 260 are rotatably mounted on the support frame 210. Three fixed sections 220 are rotatably connected to the three connecting seats 260 respectively. The three connecting seats 260 are circumferentially equidistant, and one of the connecting seats 260 is located on the front side of the support frame 210.

[0048] In this embodiment, the laser leveling instrument 100 emits a laser beam for visual reference during the construction process. The laser leveling instrument 100 is mounted on the upper end of a mounting base 310, while a support frame 210 is mounted on the lower side of the mounting base 310. Three connecting seats 260 are mounted on the support frame 210, spaced 120° apart. One connecting seat 260 is located at the front, and the other two are located on the left and right sides. The connecting seat 260 located at the front can rotate based on a horizontal axis via a hinge.

[0049] A fixed section 220, rotatably mounted on the lower end of the connecting seat 260 based on its end face, and a telescopic section 230 sliding along the fixed section 220 constitute a telescopic support leg. The three telescopic sections 230 contact the ground to support the laser leveling instrument 100. The tripod's support structure has the highest stability.

[0050] Since the ground in the construction environment may not be level, but rather inclined at various angles, when the three support legs maintain the same angle and length, the three support legs, together with the top support frame 210, mounting base 310, and laser leveling instrument 100, form a positive pyramid shape. At this time, the laser leveling instrument 100 will also tilt with the ground, and the laser beam emitted by the laser leveling instrument 100 will not be horizontal or vertical.

[0051] By controlling the increase or decrease of the volume of compressed gas filled in the gas storage chamber 250, the piston 240 and the telescopic joint 230 can be controlled to extend or shorten along the fixed joint 220, thereby leveling the support frame 210, the mounting base 310 and the laser leveling instrument 100, so that the laser leveling instrument 100 is in a horizontal state.

[0052] The lower 220 cavity of piston 240 can be a vacuum or connected to the outside air, which is different from the compressed gas in the upper gas storage cavity 250 of piston 240.

[0053] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-12 The mounting base 310 has a first connecting hole 311, a second connecting hole 312, and a third connecting hole 313 arranged in a clockwise direction.

The first connecting hole 311 is located on the front side of the mounting base 310. The first connecting hole 311, the second connecting hole 312, and the third connecting hole 313 are respectively connected to the three air storage chambers 250 through three hoses 314.

[0055] The air inlet of the air pump 330 is connected to the fourth connecting hole 321.

The gas in the front gas storage chamber 250 is pumped evenly into the two gas storage chambers 250 located on the left and right sides by the operation of the air pump 330 and the first proportional valve assembly 340.

[0057] The regulating mechanism 300 also includes a connecting assembly 360, which includes a first connecting pipe 361 disposed on the mounting base 310, two second connecting pipes 362, a second proportional valve assembly 363, and a third connecting pipe 364.

[0058] When the turntable 320 rotates to the second station, the fourth connecting hole 321 is connected to the two second connecting pipes 362 in sequence through the first connecting pipe 361 and the second proportional valve assembly 363. The two second connecting pipes 362 are then connected to the second connecting hole 312 and the third connecting hole 313 respectively. The fifth connecting hole 322 and the sixth connecting hole 323 are both connected to the first connecting hole 311 through the third connecting pipe 364. The gas in the two gas storage chambers 250 located on the left and right sides is pumped evenly into the gas storage chamber 250 located on the front side by the operation of the air pump 330.

[0059] The connecting assembly 360 also includes two fourth connecting pipes 365 and two fifth connecting pipes 366 symmetrically arranged on the mounting base 310;

The gas in the gas storage chamber 250 located on the right is pumped into the gas storage chamber 250 located on the left by the operation of the air pump 330.

[0061] When the turntable 320 rotates to the fourth station, the fourth connecting hole 321 is connected to the second connecting hole 312 through the fourth connecting pipe 365 located on the left, and the fifth connecting hole 322 is connected to the third connecting hole 313 through the fifth connecting pipe 366 located on the right. The gas in the gas storage chamber 250 located on the left is pumped into the gas storage chamber 250 located on the right by the operation of the air pump 330.

[0062] The rotating assembly 350 includes a motor 351 mounted on a mounting base 310, a first gear 352 mounted on the output shaft of the motor 351, and a second gear 353 mounted on the turntable 320, the second gear 353 meshing with the first gear 352.

[0063] In this embodiment: the mounting base 310 has a first connecting hole 311 on its front side, a second connecting hole 312 on its left side, and a third connecting hole 313 on its right side. The first connecting hole 311, the second connecting hole 312, and the third connecting hole 313 are spaced 120° apart from each other, and are respectively connected to the inner cavity of the three air storage chambers 250 through three flexible hoses 314.

[0064] The turntable 320 also has a fourth connecting hole 321, a fifth connecting hole 322, and a sixth connecting hole 323 spaced 120° apart. Furthermore, when a 360° circle is created on the mounting base 310 with a rear point of 0° and a front point of 180°, one end of the first connecting pipe 361 is connected at the 0° position. The other end of the first connecting pipe 361 is connected to the air inlet of the second proportional valve assembly 363. The two air outlets of the second proportional valve assembly 363 are then connected to one end of two second connecting pipes 362. The other ends of the two second connecting pipes 362 are respectively connected to the second connecting hole 312 and the third connecting hole 313.

[0065] Figure 5 , Figure 6 , Figure 7 and Figure 8 These represent the four working states of the regulating mechanism 300.

[0066] When the laser leveling instrument 100 tilts backward, the motor 351 drives the first gear 352 to rotate, which in turn drives the second gear 353 and the turntable 320 to rotate, causing the turntable 320 to rotate to... Figure 5 The position shown is the first work station. At this time, the air pump 330 is running, and part of the gas in the air storage chamber 250 located on the front side is extracted and enters the first proportional valve assembly 340 through the hose 314 located on the front side, the first connecting hole 311, the fourth connecting hole 321, the air inlet of the air pump 330, and the air outlet of the air pump 330 in sequence.

[0067] The first proportional valve assembly 340 can proportionally divide the incoming gas into two parts. One part passes through the fifth connecting hole 322, the second connecting hole 312, and the hose 314 on the left side sequentially into the gas storage chamber 250 on the left side. The other part passes through the sixth connecting hole 323, the third connecting hole 313, and the hose 314 on the right side sequentially into the gas storage chamber 250 on the right side. Meanwhile, the ports of the remaining first connecting pipe 361, second connecting pipe 362, third connecting pipe 364, fourth connecting pipe 365, and fifth connecting pipe 366 are blocked by the edge of the turntable 320.

[0068] At this time, the front support leg shortens, while the left and right support legs extend simultaneously, causing the support frame 210, mounting base 310, and laser leveling instrument 100 to rotate forward at a certain angle based on the left and right horizontal axes to achieve a horizontal position.

[0069] When the laser leveling instrument 100 tilts forward, the turntable 320 rotates to... Figure 6 The indicated position is the second workstation. At this time, the air pump 330 operates, and two equal volumes of gas are extracted from the left and right air storage chambers 250. These gases sequentially pass through two hoses 314 on the left and right sides, the second connecting hole 312 and the third connecting hole 313, two second connecting pipes 362, the two outlets of the second proportional valve assembly 363, the inlet of the second proportional valve assembly 363, the first connecting pipe 361, the fourth connecting hole 321, the inlet of the air pump 330, the outlet of the air pump 330, and the inlet of the first proportional valve assembly 340, entering the two outlets of the first proportional valve assembly 340. The two portions of gas exiting the two outlets of the first proportional valve assembly 340 then enter the left and right ends of the third connecting pipe 364 respectively through the fifth connecting hole 322 and the sixth connecting hole 323, and then exit from the middle end of the third connecting pipe 364, entering the first connecting hole 311 and the front hose 314, finally entering the front air storage chamber 250.

[0070] At this time, the support leg located on the front side extends, while the support legs located on the left and right sides shorten simultaneously, causing the support frame 210, mounting base 310, and laser leveling instrument 100 to rotate a certain angle to the rear based on the left and right horizontal axes, thus achieving a horizontal position.

[0071] When the laser leveling instrument 100 tilts to the left, the turntable 320 rotates to... Figure 7The indicated position is the third workstation. At this time, the air pump 330 is running, and some gas in the right-side air storage chamber 250 is extracted. This gas then passes sequentially through the right-side hose 314, the third connecting hole 313, the right-side second connecting pipe 362, the right-side fourth connecting pipe 365, the fourth connecting hole 321, the air pump 330 inlet, the air pump 330 outlet, and the first proportional valve assembly 340 inlet, entering the two outlets of the first proportional valve assembly 340. The outlet on the front side is blocked, and the gas enters the rear outlet, the left-side fifth connecting pipe 366, the left-side second connecting pipe 362, the second connecting hole 312, and the left-side hose 314, entering the left-side air storage chamber 250.

[0072] At this time, the support leg on the front side remains unchanged, the support leg on the left side is shortened, and the support leg on the right side is extended, so that the support frame 210, the mounting base 310 and the laser leveling instrument 100 are rotated to the right at a certain angle based on the front and rear horizontal axis to achieve a horizontal position.

[0073] When the laser leveling instrument 100 tilts to the right, the turntable 320 rotates to... Figure 8 The indicated position is the fourth workstation. At this time, the air pump 330 is running, and some gas in the left-side air storage chamber 250 is extracted. This gas then passes sequentially through the left-side hose 314, the third connecting hole 313, the left-side second connecting pipe 362, the left-side fourth connecting pipe 365, the fourth connecting hole 321, the air pump 330 inlet, the air pump 330 outlet, and the first proportional valve assembly 340 inlet before entering the two outlets of the first proportional valve assembly 340. The front outlet is blocked, and the gas enters the rear outlet, the right-side fifth connecting pipe 366, the right-side second connecting pipe 362, the second connecting hole 312, and the right-side hose 314 before entering the right-side air storage chamber 250.

[0074] At this time, the support leg on the front side remains unchanged, the support leg on the left side extends, and the support leg on the right side shortens, so that the support frame 210, the mounting base 310 and the laser leveling instrument 100 are rotated to the left by a certain angle based on the front and rear horizontal axis to achieve a horizontal position.

[0075] The specific structure and working principle of the air pump 330 are conventional technical methods and will not be elaborated upon.

Figures 2-12 The first proportional valve assembly 340 includes a valve body 341 disposed on the mounting base 310, and an air inlet groove 342 is provided at one end of the valve body 341, which is connected to the air outlet of the air pump 330.

[0077] Two air outlet grooves 343 are provided at the other end of the valve body 341, and two throttling holes 344 are provided inside the valve body 341. The air inlet groove 342 is connected to the two air outlet grooves 343 through the two throttling holes 344 respectively. A valve core 345 is slidably arranged inside the valve body 341. The two ends of the valve core 345 are elastically connected to the inner walls of both sides of the valve body 341 through two springs 346 respectively.

[0078] The structure of the second proportional valve assembly 363 is the same as that of the first proportional valve assembly 340.

[0079] In this embodiment: Refer to Figure 6 Gas enters the valve body 341 through the intake slot 342, and then splits into two parts, which pass through two throttling orifices 344 of equal area to reach two outlet slots 343. When the cylinders connected to the two outlet slots 343 bear the same load during charging and discharging, since the channels on the left and right sides of the first proportional valve assembly 340 are completely symmetrical, the gas entering the intake slot 342 is evenly divided into two parts and exits from the two outlet slots 343 respectively.

[0080] When the loads at the two outlet slots 343 are different, a pressure difference is generated. This pressure difference is fed back to the valve core 345, causing it to slide towards the direction of the greater load. This increases the area of ​​the channel with the greater load on the left and right sides, while decreasing the area of ​​the other channel. This continues until the valve core 345 stabilizes at a new equilibrium position. The gas supplied to the two outlet slots 343 will then be redistributed proportionally.

[0081] Spring 346 provides elastic force to valve core 345. In addition, two connecting grooves 347 are provided on valve core 345 to allow gas to flow in the part of valve body 341 where the first spring 3680 is installed.

[0082] Example 4 is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 2 and Figure 10 The laser leveling instrument 100 includes a housing 110 mounted on a mounting base 310. A laser module 120 and a pendulum 130 are disposed inside the housing 110. A first rotating shaft 140 and a second rotating shaft 150 are disposed on the pendulum 130. The first rotating shaft 140 is distributed in the left-right direction and is rotatably connected to the housing 110. The second rotating shaft 150 is distributed in the front-back direction, and the laser module 120 is rotatably connected to the second rotating shaft 150.

[0083] The housing 110 also houses a sensor 160, a magnet 170, and a battery compartment 180.

[0084] In this embodiment, a battery installed in the battery compartment 180 supplies power to the laser module 120, enabling the laser diodes and other components inside the laser module 120 to generate a laser beam. Typically, the laser module 120 can automatically level itself based on the pendulum 130 rotating in the forward / backward and left / right directions under gravity. In reality, even if the laser module 120 can automatically level itself using the pendulum 130, an alarm will be triggered to prompt the worker to adjust the tripod so that the laser leveling instrument 100 is restored to a horizontal state.

[0085] Sensor 160 can monitor the angle and direction of the pendulum 130's swing using distance measurement and other principles. Based on this, it calculates and controls the operation of motor 351 and air pump 330 via a circuit board installed inside housing 110. Magnet 170 ensures that laser module 120 swings quickly and smoothly.

[0086] The laser module 120, sensor 160, and battery compartment 180 mentioned above are all conventional technologies and will not be described in detail.
