Description

Technical Field

[0001] This utility model relates to the field of plumb bob holder technology, and in particular to a plumb bob holder for construction engineering that prevents knotting. Background Technology

[0002] A plumb line frame for construction engineering is a tool used to assist in measuring verticality during construction. It mainly consists of a support and a device for suspending the plumb line. The support is usually made of metal, which has good stability and sturdiness and can remain upright under different ground conditions on the construction site. Construction workers can judge whether the walls, columns, etc. are vertical by comparing the positional relationship between the rope and the edge of the building structure, thereby ensuring that the verticality of the construction project meets the construction standards and ensuring the stability and safety of the building structure.

[0003] Currently, most plumb bob cages rely on manual winding to rewind the line. This process is difficult to control, leading to significant line movement, tangling, and knots that affect the normal use of the plumb bob cage. Improvements are needed to address this issue. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing plumb bob frames, where the pull line is often wound manually, making it difficult to control the force during operation. This results in large movement of the pull line, causing it to become tangled and knotted, which affects the normal use of the plumb bob frame. Therefore, this invention proposes a knot-resistant plumb bob frame for construction engineering.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a plumb bob frame for construction engineering to prevent knotting, comprising a mounting rod, a rotating rod fixedly connected to one end of the mounting rod, a positioning block fixedly connected to the end of the rotating rod away from the mounting rod, a winding wheel rotatably connected to the rotating rod, a pull line fixedly connected to the inner wall of the winding wheel, a plumb bob fixedly connected to the lower end of the pull line, a positioning frame fixedly connected to the lower surface of the positioning block, one end of the positioning frame fixedly connected to the lower surface of the mounting rod, a through hole formed on the surface of the positioning frame, one end of the pull line passing through the through hole, a limit frame fixedly connected to the lower surface of the positioning frame, an auxiliary roller rotatably connected to the inner wall of the limit frame, a protrusion fixedly connected to the surface of the limit frame, a positioning rod fixedly connected to one side of the protrusion, and a swing rod rotatably connected to the positioning rod. A pressure block is fixedly connected to the end of the swing arm away from the positioning rod. A positioning roller is rotatably connected to the inner wall of the pressure block. A mounting hoop is fixedly connected to the upper surface of the mounting rod. A drive motor is fixedly connected inside the mounting hoop. A rubber wheel is fixedly connected to the drive end of the drive motor. A transmission disc is fixedly connected to the side of the winding wheel near the drive motor. The rubber wheel and the transmission disc are connected for transmission, which facilitates control of the height of the plumb bob and makes the equipment easy to use. During the descent and retrieval of the plumb bob, the positioning roller and the auxiliary roller work closely together to effectively avoid the problem of the pull line tangling and knotting. The precise positioning and guiding function of the positioning roller and the auxiliary roller ensures that the pull line always stays on the correct path during the conveying process and extends downward stably, providing stable traction for the plumb bob and ensuring that the plumb bob can descend vertically and stably, thereby ensuring the accuracy and reliability of the measurement results.

[0006] Preferably, a torsion spring is fixedly connected to the surface of the protrusion, the torsion spring is sleeved on the positioning rod, and the end of the torsion spring away from the protrusion is fixedly connected to the swing rod, so as to ensure that the swing rod drives the positioning roller to stick to the pull line, effectively limiting the swing amplitude of the pull line and avoiding the pull line from getting tangled.

[0007] Preferably, there are two torsion springs and two protrusions to ensure stable operation of the equipment.

[0008] Preferably, the cross-section of the limiting frame is U-shaped.

[0009] Preferably, the longitudinal section of the positioning frame is V-shaped.

[0010] Preferably, a counterweight plate is fixedly connected to the end of the mounting rod away from the rotating rod. The upper surface of the counterweight plate has a placement groove. Before construction, the counterweight plate is placed above the area to be tested, and counterweights are placed in the placement groove, providing a solid and stable foundation for the plumb bob frame. During operation, the stabilizing gravity generated by the counterweight plate and counterweights effectively prevents the overall equipment from shaking or shifting, ensuring that the testing work is not affected and that accurate positioning and measurement benchmarks are always maintained, providing a reliable guarantee for subsequent construction operations.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, during the descent and retrieval of the plumb bob, the positioning roller and the auxiliary roller work closely together to effectively avoid the problem of the pull line getting tangled. The precise positioning and guiding function of the positioning roller and the auxiliary roller ensures that the pull line stays on the correct path during the conveying process and extends downward stably, providing stable traction for the plumb bob and ensuring that the plumb bob can descend vertically and stably, thereby ensuring the accuracy and reliability of the measurement results.

[0012] 2. In this utility model, before construction, the counterweight plate is placed above the area to be tested, and the counterweight is placed in the placement groove, providing a solid and stable foundation for the plumb bob. During the operation, the stable gravity generated by the counterweight plate and the counterweight effectively prevents the equipment from shaking or shifting, ensuring that the testing work is not affected and that the accurate positioning and measurement benchmark are always maintained, providing a reliable guarantee for subsequent construction operations.

One end of the rod 0 is fixedly connected to a pressure block 13. A positioning roller 14 is rotatably connected to the inner wall of the pressure block 13. An installation hoop 21 is fixedly connected to the upper surface of the mounting rod 3. A drive motor 8 is fixedly connected inside the installation hoop 21. A rubber wheel 22 is fixedly connected to the drive end of the drive motor 8. A transmission disc 20 is fixedly connected to the side of the winding wheel 2 near the drive motor 8. The rubber wheel 22 is connected to the transmission disc 20 for transmission, which facilitates control of the height of the plumb bob 7 and makes the equipment easy to use. During the descent and descent of the plumb bob 7, the positioning roller 14 and the auxiliary roller 16 work closely together to effectively avoid the problem of the pull line 6 getting tangled. The precise positioning and guiding function of the positioning roller 14 and the auxiliary roller 16 ensures that the pull line 6 stays on the correct path during the conveying process and extends downward stably, providing stable traction for the plumb bob 7 and ensuring that the plumb bob 7 can descend vertically and stably, thereby ensuring the accuracy and reliability of the measurement results.

[0016] In this embodiment: a torsion spring 11 is fixedly connected to the surface of the protrusion 17. The torsion spring 11 is sleeved on the positioning rod 10. The end of the torsion spring 11 away from the protrusion 17 is fixedly connected to the swing rod 12, ensuring that the swing rod 12 drives the positioning roller 14 to stick to the pull line 6, effectively limiting the swing amplitude of the pull line 6 and preventing the pull line 6 from getting tangled.

[0017] Specifically, there are two torsion springs 11 and two protrusions 17 to ensure stable operation of the equipment.

[0018] Specifically, the cross-section of the limit frame 15 is U-shaped.

[0019] Specifically, the longitudinal section of the positioning frame 5 is V-shaped.

[0020] In this embodiment: a counterweight plate 4 is fixedly connected to the end of the mounting rod 3 away from the rotating rod 18. A placement groove 9 is provided on the upper surface of the counterweight plate 4. Before construction, the counterweight plate 4 is placed above the area to be tested, and a counterweight is placed in the placement groove 9, providing a solid and stable foundation for the plumb bob frame. During operation, the stable gravity generated by the counterweight plate 4 and the counterweight effectively prevents the overall equipment from shaking or shifting, ensuring that the testing work is not affected and that the accurate positioning and measurement benchmark are always maintained, providing a reliable guarantee for subsequent construction operations.

[0021] Working Principle: Before construction, the counterweight plate 4 is placed above the area to be tested, and the counterweight is placed in the placement groove 9 to stabilize the equipment. During operation, the drive motor 8 drives the rubber wheel 22 to rotate counterclockwise. Subsequently, the rubber wheel 22 drives the winding wheel 2 to rotate through the transmission disc 20. The pull cable 6 passes through the through hole 19 and then unwinds. Under the action of gravity, the plumb bob 7 moves steadily downward. During the displacement process, the positioning roller 14, in conjunction with the auxiliary roller 16, ensures the stable delivery of the pull cable 6 and prevents it from tangling or knotting. After the use of the plumb bob is completed, the control drive motor 8 drives the rubber wheel 22 to rotate clockwise. Then the winding wheel 2 stably winds up the pull line 6. Under the action of the torsion spring 11, the swing arm 12 drives the positioning roller 14 to stably adhere to the pull line 6 through the pressure block 13. With the help of the auxiliary roller 16, the pull line 6 is effectively clamped and stably guided to be wound up. After the plumb bob is retrieved, the object in the placement slot 9 needs to be removed to retrieve the plumb bob.
