Description

Technical Field

[0002] Construction engineering refers to the planning, investigation, design, construction, completion and other technical work and completed engineering entities for the construction, reconstruction or expansion of buildings and ancillary structures and facilities, as well as the installation of supporting lines, pipelines and equipment. It also refers to the construction of various houses and buildings. During the construction process of construction engineering, it is necessary to check the horizontal surface of the building for levelness. Levelness refers to the flatness of an object's surface, which describes the degree of deviation of the object's surface on the horizontal plane.

[0003] The existing tools for detecting the horizontality of the horizontal surface of a building include a ruler, a level, a leveling rod, a ball bearing, etc. Among them, the error of the ruler detection is relatively large. When encountering sections with multiple drops, the ruler method cannot express it. Moreover, if the drops in multiple places are less than 5mm, the result of the ruler detection can meet the standard, but the flatness of the actual horizontal surface does not meet the standard; the accuracy of the level meter combined with the leveling rod detection is high, but the detection process is relatively complicated and the detection workload is large; the error of the ball bearing detection is large, and it can only roughly reflect the levelness, and cannot accurately measure the levelness. Therefore, it is urgent to design a levelness measuring device for construction engineering construction. Summary of the invention

[0039] First, the level measuring device for construction engineering is placed at the edge of the horizontal surface of the building and an upward lifting force is applied to the assembling short cylinder 53, and then the assembling short cylinder 53 moves upward with the assembling plug 52, and then the assembling plug 52 is pulled upward from the inside of the assembling groove 51, and at the same time, the assembling short cylinder 53 squeezes the traction spring 54, the traction spring 54 is elastically compressed, and the elastic potential energy is increased, and then a rightward thrust is applied to the assembling short cylinder 53, and then the assembling short cylinder 53 moves to the right with the counterweight box 403 through the transparent hard tube 409, and then the transparent hard tube 409 slides to the right inside the open slide groove 402, and at the same time, the counterweight box 403 slides to the right from the inside of the accommodating slot 401, and then the universal joint 64 pulls the plastic tube 4 07, then the plastic tube 407 is released from the outside of the tube winding wheel 406, and then the tube winding wheel 406 works on the torsion spring 405 by rotating the cylinder 404, and then the torsion potential energy of the torsion spring 405 increases, and then the transparent hard tube 409 moves out from the inside of the open slide slot 402, and then the counterweight box 403 moves out from the inside of the accommodating slot 401, and the assembled short cylinder 53 is released. The assembled short cylinder 53 moves downward with the assembled plug 52 under the action of the elastic force of the traction spring 54 until the assembled plug 52 rests on the top surface of the counterweight box 403, and then the counterweight box 403 is placed on the horizontal plane of the building and at its edge, and at the same time, the sealing valve 410 is opened to determine the reference horizontal plane, the reference horizontal plane The horizontal plane where the liquid level 411 is detected inside the transparent hard tube 409 is then turned on, and then the travel route of the inspection mechanism 1 is set through the intelligent module 16, and then the linkage pull ring 312 is pulled, and then the linkage pull ring 312 pulls the linkage pull rod 311, and then the linkage pull rod 311 pulls the linkage slide plug 310, and then the linkage slide plug 310 slides inside the guide cavity 308 and pulls the traction rope 307, and then the traction rope 307 pulls the displacement slide plug 305 to move right, and then the displacement slide plug 305 squeezes the buffer spring 304 and moves the chamfered bevel head 306 to the right, the buffer spring 304 is elastically compressed, and the elastic potential energy increases, and then the chamfered bevel head 306 is separated from the chamfered plate 27, Then, the chamfered plate 27 moves downward with the sensing vertical rod 23 under the elastic tension of the pull-down spring 28 until the rolling steel ball 25 touches the horizontal surface of the building, and then the linkage pull ring 312 is released. The displacement slide plug 305 is reset with the chamfered bevel head 306 under the elastic force of the buffer spring 304. Then, the inspection mechanism 1 starts detection through the intelligent module 16. Then, the intelligent module 16 detects the first pressure through the pressure sensor 67. The pressure is related to the vertical height between the horizontal surface of the building directly contacted by the rolling steel ball 25 and the horizontal surface of the detection liquid 411 inside the transparent hard tube 409. The greater the vertical height, the greater the pressure, and the smaller the vertical height, the smaller the pressure. Then, the inspection mechanism 1 moves along the set route.Afterwards, the rolling steel ball 25 is always against the horizontal surface of the building under the action of the elastic force of the pull-down spring 28, and then the intelligent module 16 detects the pressure in real time through the pressure sensor 67 and compares it with the first pressure. When the horizontal surface of the building sinks, the pressure detected by the pressure sensor 67 is greater than the first pressure. When the horizontal surface of the building bulges, the pressure detected by the pressure sensor 67 is less than the first pressure. Then the intelligent module 16 compares the subsequent detected pressure with the first pressure and calculates the difference. When the difference exceeds the difference range preset in the intelligent module 16, the intelligent module 16 controls the cylindrical electromagnet 713 to be energized, and then the cylindrical electromagnet 713 generates a magnetic attraction to the strong magnetic piston 715, and then The strong magnetic piston 715 moves to the left with the extrusion piston 707 through the linkage cross bar 714, and then the extrusion piston 707 squeezes the extrusion spring 706, the extrusion spring 706 is elastically compressed, and the elastic potential energy increases, and then the color liquid storage chamber 701, the marking color liquid inside the transverse through hole 703 enters the cavity of the liquid taking chamber 704 located on the right side of the extrusion piston 707 through the liquid taking one-way valve 705, and then the intelligent module 16 controls the cylindrical electromagnet 713 to cut off the power, and then the extrusion piston 707 resets to the right under the action of the elastic force of the extrusion spring 706 and squeezes the marking color liquid, and then the marking color liquid enters the annular spray head 710 through the discharge one-way valve 709 and the infusion hose 708 and is sprayed on the building level. On the surface, it plays the role of marking. After the detection is completed, the intelligent module 16 controls the inspection mechanism 1 to stop automatically, and then closes the sealing valve 410, and holds the counterweight box 403 close to the inspection mechanism 1 through the transparent hard tube 409, and then the rotating cylinder 404 rotates with the tube winding wheel 406 under the action of the torque of the torsion spring 405, and then the plastic tube 407 is wound around the outside of the tube winding wheel 406 to retract the plastic tube 407, and then the counterweight box 403 is inserted into the accommodating slot 401, and then an upward thrust is applied to the assembled short cylinder 53 to make the assembled insert 52 higher than the top surface of the inspection vehicle body 11, and then the transparent hard tube 409 is inserted into the open slide groove 402, and then The bottom end of the assembly plug 52 is aligned with the assembly groove 51, and then the assembly short tube 53 is inserted into the assembly groove 51 with the assembly plug 52 under the action of the elastic force of the traction spring 54, and the counterweight box 403 is fixed inside the accommodating slot 401, and then an upward lifting force is applied to the sensing vertical rod 23, and then the sensing vertical rod 23 moves upward with the chamfered plate 27, and the chamfered plate 27 pulls the pull-down spring 28, and the pull-down spring 28 elastically stretches, and the elastic potential energy increases, and then the chamfered plate 27 passes over the chamfered bevel head 306 upward, and then the chamfered bevel head 306 clamps the chamfered plate 27, and then the sensing vertical rod 23 is fixed, and at this time the rolling steel ball 25 is separated from the horizontal plane of the building.
