Description

Technical Field

[0001] The utility model relates to the field of plumb lines for construction, in particular to a plumb line device for anti-knotting construction engineering construction. Background Art

[0002] A plumb bob is a thin rope with a heavy object tied to one end. When it is stationary relative to the ground, the straight line along which the rope lies is the plumb line, also known as the heavy plumb line. In construction projects, it is mainly used to detect the verticality of walls, and it can also realize the function of striking a line, so it is quite common.

[0003] In the process of using the existing plumb line device, the rope is usually pulled manually, and the weight is used to automatically vertically test. However, after the staff releases the rope, the rope automatically falls down and is prone to knotting. The staff then needs to manually untie the knot, which reduces the efficiency of the secondary test and is relatively inconvenient.

[0004] The Chinese utility model patent application number 202321071373.9 proposes a knot-proof plumb line device for construction engineering. Although it can solve the above problems, it still has certain shortcomings:

[0005] 1. It is impossible to control the distance between the plumb line, cable and wall during use, which may cause inconvenience in use;

[0006] Second, its structural setting is not convenient for application on vertical walls. When the vacuum suction cup is sucked on the vertical wall, the cable will wear against the opening of the box, and the plumb line will also touch the wall;

[0007] Third, during use, it is necessary to manually control the opening and closing of the motor in real time to start and stop the plumb line. When used by one person, it is not convenient to observe the position of the plumb line at a low place.

[0008] Based on this, the utility model proposes an anti-knotting plumb line device for construction engineering to solve the above problems. Utility Model Content

At the same time, the plumb line can be pulled out manually, and it can be locked by releasing it after it is in place, and the pull line can be automatically retracted by lifting it. It is very convenient to use.

[0030] Furthermore, a latching tooth 3 is provided on the outer circumferential side surface of the drum 4 , and a second electric push rod 2 is fixedly provided on the top wall of the control chamber 27 , and the lower movable end of the second electric push rod 2 can be latched into the latching tooth 3 and limit the rotation of the drum 4 .

[0031] Furthermore, a master controller 8 is disposed on the housing 1 , and the master controller 8 is electrically connected to the pressure sensor, the motor 5 , and the second electric push rod 2 .

[0032] Furthermore, the fixing mechanism 901 includes a mounting portion 21 hinged to the shell 1, and four vacuum suction cups 20 are fixedly provided on the mounting portion 21. The vacuum suction cups 20 are connected to a diverter 22, and the diverter 22 is connected to a vacuum pump 23. The vacuum pump 23 is fixedly provided on a vertical plate 24, and the vertical plate 24 is fixedly provided on the mounting portion 21.

[0033] Furthermore, the mounting portion 21 is penetrated by two through holes 19 , and the housing 1 is provided with two threaded holes 18 that can be adapted to the through holes 19 , and the bolts 25 can be inserted into the through holes 19 and the bolts 25 can be screwed into the threaded holes 18 to fix the mounting portion 21 .

[0041] After use, the plumb line 13 is picked up by hand. At this time, the pull line 11 is no longer subjected to the tension of the plumb line 13 itself, and the pressure on the pull line 11 at the pressure sensor is less than the normal range. At this time, the pressure sensor gives a feedback signal to the master controller 8, and the master controller 8 controls the second electric push rod 2 to no longer lock the drum 4, and at the same time controls the motor 5 to reverse and retract the pull line 11.
