Detailed implementation mode

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1, please refer to Figures 1-11 , an infrared laser ground leveling detector for construction engineering, including a laser level 100, a support mechanism 200 and an adjustment mechanism 300. The support mechanism 200 includes a support frame 210. Three fixed sections 220 are circumferentially arranged on the support frame 210. Telescopic sections 230 are slidably arranged on the three fixed sections 220. Pistons 240 are arranged on the three telescopic sections 230. The pistons 240 and the inner cavities of the fixed sections 220 form retractable gas storage cavities 250; The adjustment mechanism 300 includes a mounting seat 310 arranged on the support frame 210. The laser level 100 is arranged on the mounting seat 310. A turntable 320 is rotatably arranged on the mounting seat 310. An air pump 330 is arranged on the turntable 320; The gas distribution in the three gas storage cavities 250 is controlled by the air pump 330 to control the expansion and contraction of the three telescopic sections 230, so as to level the laser level 100; Three connecting seats 260 are rotatably arranged on the support frame 210, and three fixed sections 220 are respectively rotatably connected to the three connecting seats 260. The three connecting seats 260 are circumferentially equidistantly arranged, and one of the connecting seats 260 is located on the front side of the support frame 210.

[0035] In this embodiment: The laser level 100 can emit a laser beam for visual reference during the building construction process. The laser level 100 is installed at the upper end of the mounting seat 310, and the support frame 210 is installed on the lower side of the mounting seat 310. Three connecting seats 260 are installed on the support frame 210. The three connecting seats 260 are spaced 120° from each other, one of which is located on the front side, and the other two are located on the left and right sides. The connecting seat 260 located on the front side rotates based on the left-right horizontal axis through a hinge shaft.

[0036] The fixed section 220 rotatably installed at the lower end of the connecting seat 260 based on its end face and the telescopic section 230 sliding along the fixed section 220 form a telescopic support leg. The three telescopic sections 230 contact the ground to support the laser level 100. The support structure of the tripod has the highest stability.

[0037] Since the ground of the construction environment may not be horizontal but inclined at various angles, when the three support legs maintain the same angle and the same length, the three support legs, the top support frame 210, the mounting seat 310, and the laser level 100 form a regular pyramid. At this time, the laser level 100 will also tilt with the ground, and the laser beam emitted by the laser level 100 will not be horizontal or vertical.

[0038] By controlling the increase or decrease of the volume of the compressed gas filled in the air storage cavity 250, the piston 240 and the telescopic section 230 can be controlled to extend or contract along the fixed section 220, so as to level the support frame 210, the mounting seat 310, and the laser level 100, making the laser level 100 in a horizontal state.

[0039] The inner cavity of the lower side 220 of the piston 240 can be vacuum or communicate with the outside air, which is different from the compressed gas in the air storage cavity 250 on the upper side of the piston 240.

[0043] Figure 5 、 Figure 6 、 Figure 7 and Figure 8 These are four working states of the adjustment mechanism 300 .

[0044] When the laser level 100 tilts backward, the motor 351 drives the first gear 352 to rotate, and the first gear 352 then drives the second gear 353 and the turntable 320 to rotate, causing the turntable 320 to rotate to Figure 5 the position shown, i.e., the first working position. At this time, the air pump 330 operates, and part of the gas in the front storage cavity 250 is pumped out, passing through the front hose 314, the first communication hole 311, the fourth communication hole 321, the air inlet of the air pump 330, the air outlet of the air pump 330 in sequence and entering the first proportional valve assembly 340.

[0045] The first proportional valve assembly 340 can equally divide the incoming gas into two parts. One part passes through the fifth communication hole 322, the second communication hole 312, and the left hose 314 in sequence and enters the left storage cavity 250. The other part passes through the sixth communication hole 323, the third communication hole 313, and the right hose 314 in sequence and enters the right storage cavity 250. At this time, 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.

[0046] At this time, the front support legs shorten, and the left and right support legs elongate synchronously, causing the support frame 210, the mounting base 310, and the laser level 100 to flip forward by a certain angle based on the left - right horizontal axis and reach the horizontal position.

[0047] When the laser level 100 tilts forward, the turntable 320 rotates to Figure 6 the position shown, i.e., the second working position. At this time, the air pump 330 operates, and two parts of equal - volume gas in the left and right storage cavities 250 are pumped out, passing through the two hoses 314 on the left and right, the second communication hole 312 and the third communication hole 313, the two second connecting pipes 362, the two air outlets of the second proportional valve assembly 363, the air inlet of the second proportional valve assembly 363, the first connecting pipe 361, the fourth communication hole 321, the air inlet of the air pump 330, the air outlet of the air pump 330, and the air inlet of the first proportional valve assembly 340 in sequence and entering the two air outlets of the first proportional valve assembly 340. The two parts of gas coming out from the two air outlets of the first proportional valve assembly 340 then enter the left and right ends of the third connecting pipe 364 through the fifth communication hole 322 and the sixth communication hole 323 respectively, and then come out from the middle end of the third connecting pipe 364 and enter the first communication hole 311 and the front hose 314 and enter the front storage cavity 250.

[0048] At this time, the support leg located on the front side extends, and the support legs located on the left and right sides shorten synchronously, causing the support frame 210, the mounting base 310, and the laser level 100 to flip backward by a certain angle based on the left-right horizontal axis and reach the horizontal position.

[0049] When the laser level 100 tilts to the left, the turntable 320 rotates to Figure 7 the position shown, that is, the third working position. At this time, the air pump 330 operates, and part of the gas in the gas storage cavity 250 on the right side is pumped out, passing through the hose 314 on the right side, the third communication hole 313, the second connecting pipe 362 on the right side, the fourth connecting pipe 365 on the right side, the fourth communication hole 321, the air inlet of the air pump 330, the air outlet of the air pump 330, and the air inlet of the first proportional valve assembly 340 in sequence and entering the two air outlets of the first proportional valve assembly 340. Among them, the front air outlet is blocked, and the gas enters the rear air outlet, the fifth connecting pipe 366 on the left side, the second connecting pipe 362 on the left side, the second communication hole 312, and the hose 314 on the left side and enters the gas storage cavity 250 on the left side.

[0050] At this time, the support leg located on the front side remains unchanged, the support leg located on the left side shortens, and the support leg located on the right side extends, causing the support frame 210, the mounting base 310, and the laser level 100 to flip to the right by a certain angle based on the front-rear horizontal axis and reach the horizontal position.

[0051] When the laser level 100 tilts to the right, the turntable 320 rotates to Figure 8 the position shown, that is, the fourth working position. At this time, the air pump 330 operates, and part of the gas in the gas storage cavity 250 on the left side is pumped out, passing through the hose 314 on the left side, the third communication hole 313, the second connecting pipe 362 on the left side, the fourth connecting pipe 365 on the left side, the fourth communication hole 321, the air inlet of the air pump 330, the air outlet of the air pump 330, and the air inlet of the first proportional valve assembly 340 in sequence and entering the two air outlets of the first proportional valve assembly 340. Among them, the front air outlet is blocked, and the gas enters the rear air outlet, the fifth connecting pipe 366 on the right side, the second connecting pipe 362 on the right side, the second communication hole 312, and the hose 314 on the right side and enters the gas storage cavity 250 on the right side.

[0052] At this time, the support leg located on the front side remains unchanged, the support leg located on the left side extends, and the support leg located on the right side shortens, causing the support frame 210, the mounting base 310, and the laser level 100 to flip to the left by a certain angle based on the front-rear horizontal axis and reach the horizontal position.

[0053] The specific structure and working principle of the air pump 330 are conventional technical means and will not be elaborated.

Two ends of the valve core 345 are elastically connected to the inner walls on both sides of the valve body 341 through two springs 346; The structure of the second proportional valve assembly 363 is the same as that of the first proportional valve assembly 340.

[0055] In this embodiment: Refer to Figure 6 , gas enters the valve body 341 through the air inlet groove 342 and is then divided into two parts, which respectively reach the two air outlet grooves 343 through two throttle holes 344 with equal areas. When the load of the air charging and discharging of the cylinders connected to the two air outlet grooves 343 is the same, since the channels on the left and right sides of the first proportional valve assembly 340 are completely symmetrical, the gas entering the air inlet groove 342 is evenly divided into two parts and comes out from the two air outlet grooves 343 respectively.

[0056] When the loads at the two air outlet grooves 343 are different, a pressure difference will be generated. This pressure difference is fed back to the valve core 345, causing the valve core 345 to slide, and it slides in the direction of the larger load, so that the channel area of the larger load on the left and right sides increases, and the channel area of the other one decreases. Until the valve core 345 stabilizes at a new equilibrium position. The gas delivered to the two air outlet grooves 343 will be redistributed in equal proportion again.

[0057] The spring 346 functions to provide elastic force to the valve core 345. In addition, two communication grooves 347 are formed on the valve core 345 to make the gas also flow in the part of the valve body 341 where the first spring 3680 is installed.

[0059] In this embodiment: The battery is installed in the battery compartment 180 to supply power to the laser module 120, enabling components such as the laser diode inside the laser module 120 to operate and generate a laser beam. Usually, the laser module 120 can be automatically leveled based on the pendulum 130 rotating automatically according to gravity in the front-back and left-right directions. In reality, even if the laser module 120 can be automatically leveled by the pendulum 130, an alarm will be issued to prompt the worker to adjust the tripod to make the entire laser level 100 return to the horizontal state.

[0060] The sensor 160 can monitor the angle and direction of the pendulum 130's swing through principles such as distance measurement, and based on this, calculate and control the operation of the motor 351 and the air pump 330 through the circuit board installed inside the housing 110. The function of the magnet 170 is to enable the laser module 120 to swing quickly and smoothly.
