Description

TECHNICAL FIELD

[0001] The utility model relates to a engineering detection plumb bob stabilizing device and belongs to the engineering detection field. BACKGROUND

[0002] In order to measure the displacement and inclination of a building project, a common practice is to fix a plumb bob installation structure on the outer surface of the building and then lower the plumb bob from the structure. In this way, the plumb bob can be ensured to be vertically suspended, thereby accurately measuring the displacement and inclination angle of the building. Since a long length of rope is tied to the plumb bob, it is a common practice to wind the rope around a reel. In order to prevent the rope from being randomly unwound from the reel, a positioning screw is commonly used to limit the relative position of the reel and the support. During construction, small debris in the environment can easily adhere to the positioning screw. When the positioning screw is turned, the small debris can enter the screw hole on the support that cooperates with the positioning screw, resulting in the positioning screw becoming difficult to turn after a period of use. Therefore, it is necessary to design an engineering detection plumb bob stabilizing device that prevents the positioning screw from becoming difficult to turn. SUMMARY

DETAILED DESCRIPTION

[0021] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0022] Please refer to Figure 1 The utility model provides a technical scheme: an engineering detection plumb bob stabilizing device, including plumb bob 1, the upper surface of plumb bob 1 is installed with hanging rope 4, wherein the upper surface middle position of plumb bob 1 is installed with outer thread sleeve 2, is connected with inner thread cap 3 in the thread of outer thread sleeve 2, the end of hanging rope 4 away from rope reel 11 is penetrated through inner thread cap 3, and the end of hanging rope 4 in outer thread sleeve 2 is provided with a knot, makes the knot be in the space formed by inner thread cap 3 and outer thread sleeve 2, completes the connection of the one end of hanging rope 4 and plumb bob 1.

[0023] Refer to Figures 1-3 , Figure 5A rope reel 11 is installed at the end of the lifting rope 4 away from the hammer 1. A blind hole is formed in the middle of the rope reel 1, allowing the end of the lifting rope 4 away from the hammer 1 to be installed within the blind hole, increasing the connection range between the lifting rope 4 and the rope reel 11. A crank handle 14 is installed on one side edge of the rope reel 11. A first support plate 6 is rotatably installed on the side of the rope reel 11 away from the crank handle 14. A connecting part is installed at the end of the first support plate 6 away from the straight cylinder 12, and the connecting part is connected and fixed to a second support plate 9. The first support plate 6 and the second support plate 9 are arranged perpendicular to each other. Two small holes 13 for installing nails are opened at the end of the first support plate 6 near the second support plate 9. The small holes 13 are staggered from the rope reel 11. One side of the L-shaped plate 7 is provided with an L-shaped plate 7. One end of the L-shaped plate 7 is connected and fixed to the first support plate 6. Two through holes 8 are opened on one side of the L-shaped plate 7, which are aligned with the small holes 13. The iron nails are driven through the small holes 13 and nailed to the template, thereby restricting the rope coil 11 to the wooden template. The second support plate 9 is inserted into the brick joint, thereby restricting the rope coil 11 to the brick-concrete wall. During the nailing process, the iron nails pass through the channel formed by the through holes 8 and the small holes 13. With the support of the L-shaped plate 7, there is a gap between the head of the iron nail and the first support plate 6. When the iron nail cannot be removed from the wooden template smoothly, the screw can be cut off by using the gap between the through holes 8 and the small holes 13.

[0024] See Figures 1-4 A straight cylinder 12 is installed inside a circular opening 17 at the end of the first support plate 6 away from the second support plate 9. The straight cylinder 12 passes through the first support plate 6. A circular nut 16 is installed in the middle of the straight cylinder 12. A positioning screw 5 for limiting the relative position of the first support plate 6 and the rope reel 11 is internally threaded into the circular nut 16. One end of the positioning screw 5 extends to the outside of the straight cylinder 12. A rubber ring 15 is fitted onto the end of the positioning screw 5 near the rope reel 11 and is fixed to the positioning screw 5. The rubber ring 15 is slidably installed inside the straight cylinder 12. A cylinder cover 10 is fitted onto the cylinder. The cover 10 is fitted onto the positioning screw 5 and the cover 10 is connected and fixed to the positioning screw 5. The positioning screw 5 is screwed into the round nut 16 in the straight cylinder 12. Since the straight cylinder 12 is connected and fixed to the first support plate 6, the positioning screw 5 and the first support plate 6 are threadedly connected. Under the combined action of the rubber ring 15 and the cover 10, the effective connection part between the positioning screw 5 and the round nut 16 is hidden, preventing small debris from entering the effective connection part between the positioning screw 5 and the round nut 16, and preventing the positioning screw 5 from not turning smoothly.
