Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a convenient plumb line for construction. Background Art

[0002] Construction refers to production activities during the implementation phase of engineering construction. It is the construction process of various types of buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. During construction, it is necessary to measure the verticality of the building, which requires the use of a plumb line device.

[0003] With respect to the above-mentioned related technologies, the inventors found that when using the existing plumb line device, the hand needs to be raised to a height to position the hanging line of the plumb line, and the plumb body is vertical to the ground without shaking. At this time, the building to be measured is compared with the plumb line to determine whether the building is vertical. Raising the hand to a certain height for a long time increases the workload of the measurement. In addition, when it is necessary to measure a high building, the surveyor needs to climb to a high place to fix the plumb line, which reduces the convenience of use. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a convenient plumb line for construction. The square tube body is operated to make the plumb line rise to a certain height and close to the building to be measured. The plumb body is vertical to the ground and is stationary. The building to be measured is compared with the plumb line to determine whether the building is vertical, thereby reducing the work intensity of measurement and improving the convenience of use.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a convenient plumb line for construction, comprising: a square tube body, a first sealing plate and a second sealing plate connected to both ends of the square tube body, an automatic winding rod assembly is provided in the inner cavity of the square tube body, a plumb line is wound on the automatic winding rod assembly, and the outer end of the plumb line passes through the second sealing plate and is connected to the plumb body;

[0006] The inner cavity of the square tube body is provided with a wire loop located outside the automatic winding rod assembly, and also includes a linear driving mechanism for driving the wire loop to move along the axial direction of the automatic winding rod assembly.

[0007] By adopting the above technical scheme, when in use, the square tube body is operated so that the plumb line is lifted to a certain height, and the inclined upper end of the square tube body contacts the building, so that the plumb line is close to the building and the plumb body is vertically downward. Next, the automatic winding rod assembly is operated to rotate in the opposite direction to release the plumb line. Under the action of the gravity of the plumb body, the plumb line is straightened and close to the building to be measured, and the building to be measured is compared with the plumb line to determine whether the building is vertical. There is no need to fix the plumb line at a high place of the building by hand, which reduces the workload of measurement and improves the convenience of use. After the measurement, the automatic winding rod assembly is operated to rotate forward to rewind the plumb line. At the same time, the linear drive mechanism is operated to drive the wire ring to move back and forth along the axis direction of the automatic winding rod assembly, so that the plumb line is evenly wound on the automatic winding rod assembly, which reduces the probability of messy winding of the plumb line and improves the convenience of operation.

[0008] In a preferred example, the utility model can be further configured as follows: the automatic winding rod assembly includes a winding rod, a fixing seat 1 and a fixing seat 2 rotatably connected to both ends of the winding rod, one end of the winding rod is connected to a servo motor 1, the fixing seat 2 is provided with a circular hole, the circular hole is penetrated by the sinker line, and the fixing seat 1 and the fixing seat 2 are respectively connected to the inner wall of the square tube body.

[0009] By adopting the above technical solution, the servo motor drives the winding rod to rotate in the forward direction, and the winding rod reels the falling line. The servo motor drives the winding rod to rotate in the reverse direction, and the winding rod releases the falling line.

[0010] In a preferred example, the utility model can be further configured as follows: the linear drive mechanism includes a linear slide and a servo motor two for driving the linear slide, and the linear slide is connected to the wire loop.

[0011] By adopting the above technical solution, the servo motor 2 drives the linear slide, and the linear slide drives the wire loop to move along the axis direction of the automatic winding rod assembly.

[0012] In a preferred example, the utility model can be further configured as follows: a battery is provided in the inner cavity of the square tube, and the battery is electrically connected to the servo motor 1 and the servo motor 2 respectively.

[0013] By adopting the above technical solution and setting up the battery, it is convenient to provide electric energy to the servo motor 1 and the servo motor 2.

[0014] In a preferred example, the utility model can be further configured as follows: a controller is connected to the outer surface of the square tube, and the controller is electrically connected to the servo motor 1 and the servo motor 2 respectively.

[0015] By adopting the above technical solution and setting the controller, it is easy to control the start and stop and forward and reverse rotation of servo motor one, and it is also easy to control the start and stop and forward and reverse rotation of servo motor two.

[0016] In a preferred example, the utility model can be further configured as follows: a wear-resistant sleeve is embedded on the second sealing plate, and the sinker line is passed through the wear-resistant sleeve.

[0017] By adopting the above technical solution and using the wear-resistant sleeve, the wear caused by the relative movement of the falling line relative to the sealing plate can be reduced.

[0018] In summary, the present invention includes at least one of the following beneficial technical effects:

[0019] 1. Operate the square tube body so that the plumb line is lifted to a certain height, and the upper oblique end of the square tube body contacts the building, so that the plumb line is close to the building and the plumb body is vertically downward. Operate the automatic winding rod assembly to release the plumb line, and compare the building to be measured with the plumb line to determine whether the building is vertical. There is no need to fix the plumb line at a high place of the building by hand, which reduces the workload of measurement and improves the convenience of use.

[0020] 2. After the measurement work is completed, the linear drive mechanism drives the wire ring to move along the axis direction of the automatic winding rod assembly, so that the plumb line is evenly wound on the automatic winding rod assembly, reducing the probability of messy winding of the plumb line.
