Description

Technical Field

[0001] The present invention relates to the technical field of level measurement for building construction, and in particular to a building level measurement device and a use method thereof. Background Art

[0002] Leveling, also known as "geometric leveling", is a method of measuring the height difference between two points on a building to be measured using a level and a level rod.

[0003] In particular, during bridge construction, it is necessary to measure the height difference of different bridge support columns to ensure that their heights are consistent, thereby improving the supporting performance of the bridge. However, due to the selection of construction points for the bridge support columns, some bridge support columns have a certain inclination angle with the ground after construction. At this time, if the existing leveling method is used, the detection result will be inaccurate. At the same time, when building parallel bridges, there must be no height difference between two adjacent groups of bridge columns. If the height difference between two adjacent groups of bridge columns is small, the existing leveling method cannot quickly obtain the detection result.

[0017] S1: Install multiple sets of top seats on the top of different building top beams, and make the top surface of the top seats flush with the top of the building top beams. At the same time, install multiple sets of side seats on different building walls, and drive motor 2 so that multiple sets of hangers are at the same height and are all located in the middle of the side seats;

[0018] S2: Open the connecting valve and inject colored liquid into the connecting pipe to make it enter each transparent observation tube. At this time, observe whether the liquid in the transparent observation tube is tilted. According to the tilt degree of the liquid in the transparent observation tube, drive the motor to drive the worm to rotate, so as to mesh with the arc-shaped worm wheel, thereby forcing the movable seat to rotate in the arc-shaped rotating groove, and at the same time cooperate to push different damping spring columns on the rear side of the hanger to fine-tune the deflection angle of the hanger, so that the top surface of the liquid in all transparent observation tubes is level;

[0019] S3: Then, the colored liquid is continuously injected into the transparent observation tube through the connecting tube, so that the colored liquid lifts up the floating ball in the transparent observation tube, so that the top surface of the floating ball coincides with the zero scale line. Since the transparent observation tube and the connecting tube can form a communicating vessel, and the multiple groups of hangers are located at the same height, the liquid levels in all transparent observation tubes are at the same height, and the top surfaces of all floating balls coincide with the zero scale line.

[0020] S4: close the connecting valve on the side wall of the third group of transparent observation tubes, so that a connecting vessel is formed between the first two groups of transparent observation tubes and the connected connecting pipe, and at the same time drive the motor 3 on the top of the first group of transparent observation tubes, so that the steel cable on the wire rope roller is released. When the bottom of the steel cable is just engaged with the top of the hanger, that is, the steel cable is tightened, the input of the motor 3 is stopped and the number of turns of the lowered steel cable is recorded. According to the number of turns of the steel cable on the first group of wire rope rollers, drive the other group of wire rope rollers to release the same number of turns of the steel cable;

[0021] S5: By driving the second motor on the second set of transparent observation tubes, the screw rod is meshed with the threaded seat, thereby changing the position of the hanger on the side seat, so that the bottom of the steel cable on the second set of stranded wire rollers can be engaged with the top of the hanger, that is, the second set of steel cables is also tightened. At this time, the liquid level in the two sets of transparent observation tubes will change. The position change of the floating ball in the transparent observation tube is observed by the observation device, and the scale change of the floating ball on the sliding rod is read. After calculation, the height difference between the first two sets of buildings can be obtained;

[0022] S6: After the inspection of the first two groups of buildings is completed, the connection between the second group of steel cables and the hanger is loosened, and the position of the second group of hangers is reset so that the position of the float returns to the zero scale line, the connecting valve on the left side of the second group of transparent observation tubes is closed, and the connecting valve on the right side is opened. At the same time, the connecting valve on the right side of the third group of transparent observation tubes is closed, so that the second and third groups of transparent observation tubes and the connected connecting pipes can form a communicating vessel. Repeat the above operation to obtain the horizontal height difference between each group of buildings and the first group of buildings.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] In the above scheme, by opening the connecting valve and injecting colored liquid into the connecting pipe, it enters into each transparent observation tube. At this time, it is observed whether the liquid in the transparent observation tube is tilted. According to the tilt degree of the liquid in the transparent observation tube, the motor 1 is driven to drive the worm to rotate, thereby engaging with the arc-shaped worm wheel, thereby forcing the movable seat to rotate in the arc-shaped rotating groove, and at the same time, the different damping spring columns on the rear side of the hanger are pushed to fine-tune the deflection angle of the hanger so that the top surface of the liquid in all transparent observation tubes is horizontal. At the same time, according to the running time of the motor 1, the number of rotations of the motor 1 can be calculated, thereby obtaining the number of rotations of the worm, and according to the number of matching circles of the arc-shaped worm wheel and the worm, the deflection angle of the movable seat can be obtained, thereby calculating the inclination angle of the building to be measured and the horizontal plane.

[0025] The motor three on the top of the first set of transparent observation tubes is driven to release the steel cable on the wire rope roller. When the bottom of the steel cable is just engaged with the top of the hanger, the steel cable is tightened. At this time, the input of motor three is stopped and the number of turns of the lowered steel cable is recorded. According to the number of turns of the steel cable on the first set of wire rope rollers, the other set of wire rope rollers is driven to release the same number of turns of steel cable. By driving the motor two on the second set of transparent observation tubes, the screw is engaged with the threaded seat, thereby changing the position of the hanger on the side seat, so that the bottom of the steel cable on the second set of wire rope rollers can be engaged with the top of the hanger, that is, the second set of steel cables is also tightened. At this time, the liquid level in the two sets of transparent observation tubes will change. The position change of the float in the transparent observation tube is observed by the observation device. By reading the scale change of the float on the slide bar, the height difference between the first two sets of buildings can be obtained through calculation. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The method for using the building level measuring device provided by the present invention is to install multiple groups of top seats 240 on the tops of different building top beams, and make the top surfaces of the top seats 240 flush with the tops of the building top beams, and at the same time install multiple groups of side seats 200 on different building walls, and drive motor 230 to make multiple groups of hangers 101 at the same height and all located in the middle of the side seats 200.

[0053] Open the connecting valve 145 and inject colored liquid into the connecting tube 147 to allow it to enter each transparent observation tube 141. At this time, observe whether the liquid in the transparent observation tube 141 is tilted. According to the degree of tilt of the liquid in the transparent observation tube 141, drive the motor 128 to drive the worm 123 to rotate, thereby engaging with the arc-shaped worm gear 118, thereby forcing the movable seat 120 to rotate in the arc-shaped rotating groove 104. At the same time, cooperate with the different damping spring columns 151 on the rear side of the push bracket 101 to fine-tune the deflection angle of the hanger 101 so that the top surface of the liquid in all transparent observation tubes 141 is level.

[0054] Thereafter, colored liquid continues to be injected into the transparent observation tube 141 through the connecting tube 147, so that the floating ball 144 in the transparent observation tube 141 is lifted up, and the top surface of the floating ball 144 coincides with the zero scale line 148. Since the transparent observation tube 141 and the connecting tube 147 can form a communicating vessel, and the multiple groups of hangers 101 are located at the same height, the liquid levels in all transparent observation tubes 141 are the same, and the top surfaces of all floating balls 144 coincide with the zero scale line 148.

[0055] Close the connecting valve 145 on the side wall of the third group of transparent observation tubes 141 to form a connecting vessel between the first two groups of transparent observation tubes 141 and the connected connecting pipe 147, and at the same time drive the motor 3 245 on the top of the first group of transparent observation tubes 141 to release the steel cable 246 on the wire rope roller 244. When the bottom of the steel cable 246 is just engaged with the top of the hanger 101, that is, the steel cable 246 is tightened, the input of the motor 3 245 is stopped and the number of turns of the lowered steel cable is recorded. According to the number of turns of the steel cable 246 on the first group of wire rope rollers 244, drive the other group of wire rope rollers 244 to release the same number of turns of the steel cable 246.

[0056] By driving the motor 230 on the second group of transparent observation tubes 141, the screw 220 is meshed with the threaded seat 160, thereby changing the position of the hanger 101 on the side seat 200, so that the bottom of the steel cable 246 on the second group of twisted wire rollers 244 can be engaged with the top of the hanger 101, that is, the second group of steel cables 246 are also tightened. At this time, the liquid level in the two groups of transparent observation tubes 141 will change, and the position change of the float 144 in the transparent observation tube 141 is observed through the observation device 106. By reading the scale change of the float 144 on the slide bar 142, the height difference between the first two groups of buildings can be obtained through calculation.

[0057] After the inspection of the first two groups of buildings is completed, the connection between the second group of steel cables 246 and the hanger 101 is loosened, and the position of the second group of hangers 101 is reset at the same time, so that the position of the float 144 returns to the zero scale line 148, the connecting valve 145 on the left side of the second group of transparent observation tubes 141 is closed, the connecting valve 145 on the right side is opened, and the connecting valve 145 on the right side of the third group of transparent observation tubes 141 is closed at the same time, so that the second and third groups of transparent observation tubes 141 and the connected connecting pipes 147 can form a communicating vessel, and the above operations are repeated to obtain the horizontal height difference between each group of buildings and the first group of buildings.
