Description

Technical Field

[0001] The present invention relates to the technical field of crane beam installation, and specifically to a device and method for measuring the levelness of crane beam installation. Background Art

[0002] The levelness of the steel crane beam installation directly affects the running stability and safety of the crane. If the crane beam is not installed horizontally, it will cause the crane to shake and deviate during operation, affecting the normal operation of the crane, and even may cause equipment damage, posing a great safety hazard. Therefore, it is necessary to measure the levelness of the crane beam during the installation process. When measuring the levelness and perpendicularity of the crane beam, the traditional tools used are spirit levels and theodolites. The traditional measurement method requires the surveyors to work at heights, and the measuring instruments are also erected on the upper flange of the crane beam for measurement. For the surveyors, the traditional method requires always operating the measuring instruments at high altitudes for measurement, which is very dangerous. At the same time, there is instability in erecting the instruments on the upper flange of the crane beam, and the measurement data has large errors.

[0003] After retrieval, the patent with the publication number CN111780733B discloses a method for measuring the levelness and perpendicularity of crane beams. Through the use of measuring tools, it avoids placing the level and theodolite at high altitudes for measurement, reduces the risk of working at heights, and only requires an ordinary tape measure tool for assistance and measuring with a level on the ground to determine whether the levelness and perpendicularity of the crane beam meet the requirements and obtain the specific offset amount. Moreover, the measuring tool is simple to manufacture and has high precision.

[0004] Although the above solution can measure the levelness of the crane beam by using a level on the ground in cooperation with measuring tools, in the actual use process, since the plumb bob used is connected to the connecting rod by a rope, it will shake during the hoisting process of the crane beam and it is difficult to quickly stabilize in a short time. And the plumb bob and its rope are small in volume, and it is difficult to observe at a long distance, so the measurement is rather troublesome. Summary of the Invention

[0005] The present invention aims to solve the above problems, and thus provides a device and method for measuring the levelness of crane beam installation.

[0006] The technical solution adopted by the present invention to solve the above problems is: A device for measuring the horizontal degree of crane beam installation, comprising a handheld terminal, a hose and two data acquisition parts. The data acquisition part includes a mounting rack and a T-shaped liquid storage pipe. The T-shaped liquid storage pipe is fixed to the crane beam through the mounting rack. The T-shaped liquid storage pipe is rotatably installed on the mounting rack. The T-shaped liquid storage pipes of the two data acquisition parts are interconnected through a hose. Water is provided in the T-shaped liquid storage pipe and the hose. A floating plate is arranged in the T-shaped liquid storage pipe. A laser distance measuring probe is detachably installed at the top end of the T-shaped liquid storage pipe. A data collector is fixedly installed at the bottom end of the T-shaped liquid storage pipe. The laser distance measuring probe is connected to the corresponding data collector by a wire. The data collector is in wireless communication connection with the handheld terminal.

[0007] Further, the mounting rack includes a portal plate buckled on the crane beam. A threaded hole is formed in one side plate of the portal plate. A hand-tightening bolt is threadedly connected in the threaded hole. One end of the hand-tightening bolt located inside the portal plate is rotatably connected to a top plate. A mounting plate is fixedly connected to the outer wall of the other side plate of the portal plate. The T-shaped liquid storage pipe is rotatably connected to the mounting plate through a damping bearing seat.

[0008] Further, a setscrew is connected to the top of the portal plate through a threaded hole; the installation height of the T-shaped liquid storage pipe can be adjusted within a certain range.

[0009] Further, the T-shaped liquid storage pipe is composed of a vertical pipe and a horizontal pipe that are perpendicularly connected. The floating plate is located in the vertical pipe. The water level height in the vertical pipe is higher than that in the horizontal pipe. The top end of the vertical pipe is connected to the laser distance measuring probe. The bottom end of the vertical pipe is a closed structure, and the data collector is fixedly connected to the bottom end of the vertical pipe. The mounting plate is rotatably connected to the horizontal pipe through a damping bearing seat. One end of the horizontal pipe away from the T-shaped liquid storage pipe is connected to the hose through a rotary joint; the T-shaped liquid storage pipe can rotate relative to the mounting plate, and by installing the data collector at the bottom end of the vertical pipe, a counterweight function can be achieved, so that when the crane beam is inclined, the vertical pipe can still maintain a vertical state. Through the setting of the rotary joint, the hose can be prevented from interfering with the rotation of the T-shaped liquid storage pipe.

[0010] Further, a data processing module, a wireless communication module and a storage battery are arranged in the data collector.

[0011] Further, a top cover is detachably connected to the top end of the T-shaped liquid storage pipe. The laser distance measuring probe is fixedly installed through the top cover. A plurality of ventilation holes are formed through the top of the top cover; it is convenient to fix the laser distance measuring probe.

[0012] Further, the data acquisition parts are installed at both ends of the crane beam. The hose is fixedly connected to the outer wall of the crane beam; when the crane beam is inclined, the height difference between the two ends is the largest, and the measurement effect is more obvious.

[0013] A method for using a device for measuring the horizontal degree of crane beam installation is carried out according to the following steps: Step 1: Horizontally place the crane beam on the ground, semi-surround and fasten the two gantry plates at the top ends of the crane beam, then rotate the hand-tightening bolts to make the top plate fit against the outer wall of the crane beam, temporarily position the gantry plates, and then use tape to temporarily fix the hose segments on the outer wall of the crane beam; Step 2: Rotate the jackscrews at the top of the gantry plates to adjust the relative height of the two T-shaped liquid storage tubes, so that the two T-shaped liquid storage tubes are kept at the same horizontal height. Then tighten the hand-tightening bolts again to make the top plate closely adhere to the outer wall of the crane beam, and fix the gantry plates on the crane beam; Step 3: During the hoisting process of the crane beam, once the crane beam tilts, there will be a height difference between the two T-shaped liquid storage tubes. The liquid levels in the two T-shaped liquid storage tubes will remain the same under the action of the communicating vessel principle. The data collector monitors the distance of the floating plate through the laser ranging probe and sends the distance data to the handheld terminal in a wireless communication manner, so as to monitor the levelness of the crane beam in real time.

[0014] The present invention adopting the above technical solution, compared with the prior art, its prominent feature is: The structure of the present invention is simple and the installation is convenient. The two T-shaped liquid storage tubes interconnected by the hose can, under the action of the communicating vessel principle, when the crane beam tilts in its length direction, cause a height difference between the two T-shaped liquid storage tubes, but the liquid levels in the T-shaped liquid storage tubes still remain on the same horizontal plane, so that the distances between the two floating plates and the laser ranging probe change. The data collector collects the distances between the floating plates and the laser ranging probe and sends the distance data to the handheld terminal, and the staff can timely and accurately know the levelness of the current crane beam in its length direction through the handheld terminal, which is more convenient to use.

Specific embodiments

[0016] The present invention will be further described below in conjunction with embodiments. The purpose is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0017] See Figures 1-5 , a device for measuring the horizontal degree of crane beam installation, including a handheld terminal 19, a hose 9 and two data acquisition parts. The data acquisition part includes a mounting frame and a T-shaped liquid storage pipe 7. The T-shaped liquid storage pipe 7 is fixed to the crane beam 20 through the mounting frame. The T-shaped liquid storage pipe 7 is rotatably installed on the mounting frame. The T-shaped liquid storage pipes 7 of the two data acquisition parts are interconnected through the hose 9. Water 10 is provided in the T-shaped liquid storage pipe 7 and the hose 9. A floating plate 11 is provided in the T-shaped liquid storage pipe 7. A laser ranging probe 13 is detachably installed at the top end of the T-shaped liquid storage pipe 7. A data collector 15 is fixedly installed at the bottom end of the T-shaped liquid storage pipe 7. The laser ranging probe 13 is connected to the corresponding data collector 15 by wire. The data collector 15 is wirelessly communicatively connected to the handheld terminal 19.

[0018] By using the hose 9 to interconnect the two T-shaped liquid storage pipes 7, under the action of the communicating vessel principle, the liquid levels inside them can be kept on the same horizontal plane. Therefore, after the two T-shaped liquid storage pipes 7 are respectively installed at both ends of the crane beam 20, when the crane beam 20 is inclined in its length direction, a height difference will occur between the two T-shaped liquid storage pipes 7, but the liquid levels in the T-shaped liquid storage pipes 7 are still on the same horizontal plane, thereby changing the distance between the two floating plates 11 and the laser ranging probe 13. The data collector 15 collects the distance between the floating plate 11 and the laser ranging probe 13 and sends the distance data to the handheld terminal. The staff can then timely and accurately know the horizontal degree of the current crane beam 20 in its length direction through the handheld terminal 19, which is more convenient to use.

[0019] The mounting frame includes a portal plate 1 buckled on the crane beam 20. A threaded hole is opened on one side plate of the portal plate 1. A hand-tightening bolt 2 is threadedly connected in the threaded hole. One end of the hand-tightening bolt 2 located inside the portal plate 1 is rotatably connected to a top plate 3. A mounting plate 5 is fixedly connected to the outer wall of the other side plate of the portal plate 1. The T-shaped liquid storage pipe 7 is rotatably connected to the mounting plate 5 through a damping bearing seat 6. By tightening the hand-tightening bolt 2 to make the top plate 3 closely adhere to the crane beam 20, the portal plate 1 can be fixed on the crane beam 20, and the operation is simple and convenient.

[0020] The top of the portal plate 1 is connected with a setscrew 4 through a threaded hole; by adjusting the length of the setscrew 4 extending into the portal plate 1, so that the setscrew 4 abuts against the top of the crane beam 20, the installation height of the T-shaped liquid storage pipe can be adjusted within a certain range.

[0021] The T-shaped liquid storage pipe 7 is composed of a vertical pipe and a horizontal pipe that are perpendicularly connected and communicated. The floating plate 11 is located in the vertical pipe. The water level height in the vertical pipe is higher than that of the horizontal pipe. The top end of the vertical pipe is connected with a laser ranging probe 13. The bottom end of the vertical pipe is a closed structure, and the data collector 15 is fixedly connected to the bottom end of the vertical pipe. The mounting plate 5 is rotationally connected to the horizontal pipe through a damping bearing seat 6. One end of the horizontal pipe away from the T-shaped liquid storage pipe 7 is communicated with a hose 9 through a rotary joint 8; the T-shaped liquid storage pipe 7 can rotate relative to the mounting plate 5, and by installing the data collector 15 at the bottom end of the vertical pipe, a counterweight function can be achieved, so that when the crane beam 20 is inclined, the vertical pipe can still maintain a vertical state. Through the setting of the rotary joint 8, the hose 9 can be prevented from interfering with the rotation of the T-shaped liquid storage pipe 7.

[0022] A data processing module 16, a wireless communication module 17 and a storage battery 18 are arranged in the data collector 15.

[0023] The top end of the T-shaped liquid storage pipe 7 is detachably connected with a top cover 12. The laser ranging probe 13 is fixedly installed through the top cover 12. A plurality of air vents 14 are arranged through the top of the top cover 12; the setting of the top cover 12 facilitates the fixation of the laser ranging probe, and the air vents 14 can make the air pressure inside the T-shaped liquid storage pipe 7 consistent with the outside.

[0024] The data acquisition part is installed at both ends of the crane beam 20, and the hose 9 is fixedly connected to the outer wall of the crane beam 20; when the crane beam 20 is inclined, the height difference between the two ends is the largest, and the measurement effect is more obvious.

[0025] A method for using a device for measuring the levelness of a crane beam installation is carried out according to the following steps: Step 1: Horizontally place the crane beam 20 on the ground, buckle the two portal plates 1 semi-surroundingly on the top of both ends of the crane beam 20, and then rotate the hand-tightening bolt 2 so that the top plate 3 fits against the outer wall of the crane beam 20 to temporarily position the portal plate 1, and then use tape to temporarily fix the hose 9 on the outer wall of the crane beam 20. Step 2: Rotate the setscrew 4 on the top of the portal plate 1 to adjust the relative height of the two T-shaped liquid storage pipes 7 so that the two T-shaped liquid storage pipes 7 are at the same horizontal height, and then tighten the hand-tightening bolt 2 again so that the top plate 3 closely adheres to the outer wall of the crane beam 20 to fix the portal plate 1 on the crane beam. Step 3: During the process of hoisting the crane girder 20, once the crane girder 20 inclines, there will be a height difference between the two T-shaped liquid storage pipes 7. The liquid levels in the two T-shaped liquid storage pipes 7 will remain the same under the action of the communicating vessel. The data collector 15 monitors the distance of the floating plate 11 through the laser ranging probe 13 and sends the distance data to the handheld terminal 19 in a wireless communication manner, so as to monitor the levelness of the crane girder 20 in real time.

[0026] The structure of the present invention is simple and easy to install. The two T-shaped liquid storage pipes interconnected by hoses can, under the action of the communicating vessel principle, when the crane girder inclines in its length direction, cause a height difference between the two T-shaped liquid storage pipes, but the liquid levels in the T-shaped liquid storage pipes are still on the same horizontal plane, thereby changing the distances between the two floating plates and the laser ranging probe. The data collector collects the distances between the floating plates and the laser ranging probe and sends the distance data to the handheld terminal. The staff can then timely and accurately know the levelness of the current crane girder in its length direction through the handheld terminal, which is more convenient to use.
