It includes a support frame, with a fixed shaft rotatably connected inside the support frame. Two spools, a first spool and a second spool, are fixedly mounted on the outside of the fixed shaft. A first fixed rope is wound inside the first spool, and a second fixed rope is wound inside the second spool. A threaded rod is rotatably connected inside the support frame, and a movable plate is threadedly connected to the outer surface of the threaded rod. Through the cooperation between the second fixed rope and the movable plate, when the plumb bob is released to a suitable position, the lead weight causes the second fixed rope to droop, or the second fixed rope can be manually pulled to stop.

Description

Technical Field

[0001] This utility model belongs to the technical field of verticality detection devices, and particularly relates to a self-calibrating verticality detection device for building engineering. Background Technology

[0002] In construction engineering, the verticality of a building is of paramount importance, as it affects the building's support and structural stability. Therefore, verticality testing is required at the initial, middle, and final stages of a construction project, such as for the construction of bridge supports or building walls.

[0003] In the verticality testing of building engineering, the plumb bob method is one of the most accurate testing methods, and its operation is also relatively simple. When using it, the support frame is fixed above the support, and then the plumb bob and the fixing rope are controlled to hang vertically. The result can be obtained quickly by measuring the distance between the fixing rope and the metal support or building wall. However, the existing plumb bob method does not have a structure for auxiliary fixing and positioning of the plumb bob in the initial stage of measurement. Since the plumb bob hangs naturally by gravity, it is easy to shake when the plumb bob is lowered, which can cause problems that cannot be detected. It cannot help the plumb bob to come to a stop quickly, so it is necessary to wait for the plumb bob to come to a stop naturally or apply external resistance to make it stop, which is not convenient to operate.

[0004] In view of this, we propose a self-calibrating verticality detection device for building engineering. Utility Model Content

[0005] The purpose of this invention is to provide a self-calibrating verticality detection device for building engineering, so as to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a self-calibrating verticality detection device for building engineering, including a support frame, a fixed shaft rotatably connected inside the support frame, and a first spool and a second spool fixedly installed outside the fixed shaft. A first fixing rope is wound inside the first spool, and a second fixing rope is wound inside the second spool. The support frame is internally rotatably connected to a threaded rod, and the outer surface of the threaded rod is threadedly connected to a movable plate. The outer surface of the movable plate is respectively fixedly installed with positioning ring one and positioning ring two. A cone is fixedly installed at one end of the first fixing rope, and a connecting hole is opened inside the cone. A lead block is fixedly installed at one end of the second fixing rope.

[0007] In this technical solution, the rotation of the fixed shaft can control the rotation of spool one and spool two. At this time, fixed rope one and fixed rope two can be released, and the plumb bob can hang down naturally. Under the action of the lead block, fixed rope two is always in a vertical state. The position of the moving plate can be controlled by adjusting the rotation of the threaded rod, and the top positions of fixed rope one and fixed rope two can be adjusted. When the plumb bob hangs down naturally, the weight of the lead block or the assistance of the worker pulls down fixed rope two to help position the plumb bob. At this time, the plumb bob can quickly come to a stop, which can be used for rapid testing in construction projects.

[0008] In the above technical solution, a strong magnetic plate is fixedly installed on the right outer surface of the support frame, and a horizontal bubble meter is installed on the top of the support frame.

[0009] In this technical solution, a strong magnetic plate is used to fix the support frame to the metal bracket, and a level bubble meter is used to detect the levelness of the support frame.

[0010] In the above technical solution, further, the left side of the support frame is threaded with a fixing bolt, one end of which is in contact with the outer surface of the fixing shaft.

[0011] In this technical solution, the fixing bolt can limit the rotation of the fixing shaft and quickly position the fixing rope one and fixing rope two.

[0012] In the above technical solution, further, indicator plates are fixedly installed on both sides of the movable plate, the outer surface of the indicator plates is slidably connected to the inside of the support frame, and scales are provided on both the front and rear sides of the support frame.

[0013] In this technical solution, the position of the moving plate is located by the combination of an indicator plate and a ruler, which facilitates distance measurement.

[0014] In the above technical solution, further, the outer surfaces of the first fixing rope and the second fixing rope are slidably connected to the interiors of the first positioning ring and the second positioning ring, respectively, and the first positioning ring and the second positioning ring are arranged adjacent to each other on the same side of the moving plate.

[0015] In this technical solution, the center lines of fixed rope one and fixed rope two are aligned with the outer edge of the indicator plate. By adjusting the position of the moving plate, the top positions of fixed rope one and fixed rope two can be controlled. With the cooperation of positioning ring one and positioning ring two, fixed rope one and fixed rope two can always be in a parallel state.

[0016] In the above technical solution, the connecting holes are arranged in a ring array inside the cone, and the connecting holes penetrate the interior of the cone.

[0017] In this technical solution, the diameter of the connecting hole is larger than the diameter of the second fixing rope, which facilitates the placement of the second fixing rope.

[0018] In the above technical solution, the outer surface of the second fixing rope is slidably connected to the inside of the connecting hole, and the outer surface of the lead block is slidably connected to the outer surface of the cone.

[0019] In this technical solution, both the lead block and the fixing rope can be inserted into the connecting hole to reduce the swaying of the lead weight.

[0020] The beneficial effects of this utility model are: 1. The self-calibrating verticality testing device used in this construction project, through the cooperation between the fixed rope and the moving plate, controls the rotation of the fixed shaft during measurement. At this time, the first and second spools can release the first and second fixed ropes. When the plumb bob is released to the appropriate position, the lead block drives the second fixed rope to hang down, or the second fixed rope can be manually pulled to stop. At this time, the bidirectional limiting of the first and second fixed ropes prevents the swing of the plumb bob, which can help the plumb bob to stop quickly, reduce the extra waiting time, and realize the function of assisting the plumb bob to stop quickly, so as to facilitate the rapid measurement of verticality using the plumb bob.

[0021] 2. The self-calibrating verticality testing device used in this construction project, by setting up components such as threaded rods and moving plates, can control the movement of the moving plate inside the support frame by rotating the threaded rods. When there are obstacles on the testing plane, it can control the top positions of the fixed rope one and fixed rope two, which facilitates the testing. Attached Figure Description

The support frame 1 is internally rotatably connected to a threaded rod 7, and the outer surface of the threaded rod 7 is threadedly connected to a movable plate 8. The outer surface of the movable plate 8 is respectively fixedly installed with a positioning ring 9 and a positioning ring 10. A cone 11 is fixedly installed at one end of the fixing rope 5. A connecting hole 12 is opened inside the cone 11. A lead block 13 is fixedly installed at one end of the fixing rope 6.

[0027] The rotation of fixed shaft 2 controls the rotation of spool 3 and spool 4, allowing fixed rope 5 and fixed rope 6 to be released and the plumb bob to hang down naturally. Under the action of lead block 13, fixed rope 6 remains vertical. The position of moving plate 8 can be controlled by adjusting the rotation of threaded rod 7, allowing adjustment of the top positions of fixed rope 5 and fixed rope 6. When the plumb bob hangs down naturally, the weight of lead block 13 or the assistance of workers pulls down fixed rope 6 to help position the plumb bob. At this time, the plumb bob can quickly come to a stop, enabling rapid testing in construction projects.

In addition to the technical solutions of the above examples, it also has the following technical features: a strong magnetic plate 14 is fixedly installed on the right outer surface of the support frame 1, and a horizontal bubble meter 15 is installed on the top of the support frame 1.

[0029] The strong magnetic plate 14 can be used to fix the support frame 1 on the metal bracket, which is suitable for measurement at the location of the metal bridge. The level bubble meter 15 can be used to detect the levelness of the support frame 1, which is convenient for adjusting the position.

[0030] Example 3: This example provides a self-calibrating verticality detection device for building engineering. In addition to the technical solutions of the above examples, it also has the following technical features: the left side of the support frame 1 is threaded with a fixing bolt 16, and one end of the fixing bolt 16 is in contact with the outer surface of the fixing shaft 2.

[0031] The fixing bolt 16 can limit the rotation of the fixing shaft 2. When the fixing shaft 2 is adjusted and the fixing bolt 16 is tightened, one end of the fixing bolt 16 will press against the outside of the fixing shaft 2. At this time, the rotation of the fixing shaft 2 is restricted, which can quickly position the fixing rope 1 5 and the fixing rope 2 6.

[0032] Example 4: This example provides a self-calibrating verticality detection device for building engineering.

[0033] The indicator plate 17 can assist the movement of the movable plate 8. The position of the movable plate 8 can be controlled by rotating the threaded rod 7. The position of the movable plate 8 can be positioned by the cooperation of the indicator plate 17 and the scale 18, which facilitates distance measurement.

[0034] Example 5: This example provides a self-calibrating verticality detection device for building engineering.

In addition to the technical solutions of the above examples, it also has the following technical features: the connecting holes 12 are arranged in a ring array inside the cone 11, and the connecting holes 12 penetrate the interior of the cone 11.

[0037] The diameter of the connecting hole 12 is larger than the diameter of the fixing rope 6. The connecting holes 12 arranged in a ring array are adapted to various positions after the plumb bob rotates, making it convenient to place the fixing rope 6.

[0038] Example 7: This example provides a self-calibrating verticality detection device for building engineering.

At this time, fixing rope 2 6 is vertical under the action of lead block 13. Through the limiting of two sets of parallel fixing rope 1 5 and fixing rope 2 6, the swaying of the lead hammer is reduced. The staff can also pull down lead block 13 to help fixing rope 2 6 be vertical, so that the lead hammer can be brought to a stop more quickly.

[0040] Working principle: The rotation of fixed shaft 2 controls the rotation of spool 1 3 and spool 2 4, which releases fixed rope 1 5 and fixed rope 2 6. The position of moving plate 8 can be adjusted by rotating threaded rod 7. The top positions of fixed rope 1 5 and fixed rope 2 6 can be adjusted by positioning ring 1 9 and positioning ring 2 10. When the plumb bob hangs down naturally, lead block 13 is inserted through connecting hole 12. The weight of lead block 13 and the assistance of the worker in pulling quickly bring the plumb bob to a stop, which is convenient for measurement in construction engineering.
