Technical Field

[0001] The present application relates to the technical field of line-laying and measurement, and in particular to a ceiling line-laying device. Background Art

[0002] During the construction process, a large number of equipment and pipelines need to be arranged on the ceiling. During the pipeline construction process of the ceiling, a line-laying device is usually used to mark the construction positioning line on the ceiling to form a visible line to facilitate construction.

[0003] In the related art, a Chinese patent document with publication number CN105863282A discloses a ceiling line-laying device, which includes two operating rods and an ink fountain mounted on one of the operating rods. The ink fountain has a coil built into it, a rotating shaft is provided in the middle of the coil, and a rotating handle is provided at one end of the rotating shaft. One end of the coil wire passes through a flexible wire tube, a pulley, a wire pressing ring, an elastic wire rope, a groove at the top of the rod, and is fixed at the center of the rod. When in use, one operating rod is pressed against the ceiling, and then the other operating rod is moved to another point on the straight line to be marked on the ceiling and pressed against the ceiling. Then, the elastic wire rope is pulled down and then released. The coil wire with ink adheres to the ceiling to mark the positioning line.

[0004] Regarding the above-mentioned related technologies, since most ceilings have a curved top structure, when the elastic rope is pulled down and then released, the coil wire is not easy to fit with the inner wall of the ceiling, making it difficult to mark the ink on the ceiling, and the scope of application is relatively small. Summary of the Invention

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a ceiling wire laying device. Figure 1 and Figure 2The ceiling line-laying device includes operating rods 1 on both sides, which are parallel to each other. The coil wire with ink spans the top of the operating rods 1 on both sides. The specific setting method of the coil wire is consistent with that in the relevant technology and will not be described in detail here. The top and bottom ends of the operating rod 1 are fixedly connected to support plates 15. A guide rod 16 is fixedly connected between the two support plates 15 on the same operating rod 1. The length direction of the guide rod 16 is parallel to the length direction of the operating rod 1. A slider 9 is slidably sleeved on the guide rod 16, and the sliding direction of the slider 9 is parallel to the length direction of the operating rod 1; a driving member for driving the corresponding slider 9 to slide is provided on the support plate 15, and the driving member includes a screw rod 10 that is rotatably passed through the two support plates 15 of the same operating rod 1. The rotation axis of the screw rod 10 is parallel to the length direction of the operating rod 1. The slider 9 is threadedly connected to the corresponding screw rod 10. The bottom end of the screw rod 10 is fixedly connected to a first handle 17 to facilitate the rotation of the screw rod 10.

[0034] Reference Figure 1 and Figure 2 A telescopic rod 2 is hinged between the sliders 9 on both sides. The two ends of the telescopic rod 2 are hinged on the corresponding sliders 9 respectively. The hinge axis of the telescopic rod 2 is perpendicular to the length direction of the operating rod 1. The arrangement direction of the telescopic rod 2 and the operating rods 1 on both sides are located in the same plane. The telescopic direction of the telescopic rod 2 is parallel to the direction of the line connecting the top ends of the operating rods 1 on both sides. The longitudinal section of the telescopic rod 2 is a rectangle.

[0035] Reference Figure 2 and Figure 3 , a sliding sleeve is provided on the telescopic rod 2 with a sliding seat 3, and the sliding direction of the sliding seat 3 is parallel to the telescopic direction of the telescopic rod 2. A mounting seat 4 is slidingly provided on the sliding seat 3, and the mounting seat 4 is located above the sliding seat 3. The sliding direction of the mounting seat 4 is perpendicular to the length direction of the telescopic rod 2. The mounting seat 4 slides in the direction close to or away from the ceiling. A guide telescopic rod 18 is fixed between the mounting seat 4 and the sliding seat 3. In this embodiment, two guide telescopic rods 18 are provided. The telescopic direction of the guide telescopic rod 18 is parallel to the sliding direction of the mounting seat 4. A bracket 12 is provided on the side of the mounting seat 4 away from the sliding seat 3, and a support for contacting the ceiling is rotatably provided on the bracket 12. Roller 5, the rotation axis of roller 5 is perpendicular to the arrangement direction of the operating rods 1 on both sides, and the roller 5 is located below the coil line between the operating rods 1 on both sides. The sliding seat 3 is provided with a pushing member for pushing the mounting seat 4 to drive the roller 5 to slide toward the direction close to the ceiling top. The pushing member includes a spring 7 for pushing the mounting seat 4 to drive the roller 5 to slide toward the direction close to the ceiling top. The spring 7 corresponds one-to-one to the guide telescopic rod 18. The spring 7 is movably mounted on the corresponding guide telescopic rod 18. One end of the spring 7 is fixedly connected to the top wall of the sliding seat 3, and the other end is fixedly connected to the bottom wall of the mounting seat 4; the telescopic rod 2 is provided with a sliding assembly 6 for driving the sliding seat 3 to slide.

[0036] When it is necessary to mark the positioning line of the ceiling of the curved roof, first, press one operating rod 1 against the ceiling, then move the other operating rod 1 against another point of the positioning line that needs to be marked, and then rotate the first handles 17 on both sides. The first handles 17 drive the slider 9 to move to the required position, so that the extension direction of the telescopic rod 2 is parallel to the direction of the connecting line of the vertices of the operating rods 1 on both sides. At this time, the roller 5 is located below the coil line, and the roller 5 is in contact with the ceiling top and presses the coil line on the ceiling top. The spring 7 is in a compressed state, so that the spring 7 always has a thrust on the mounting seat 4 toward the ceiling top; then the sliding seat 3 is driven by the sliding assembly 6 to drive the mounting seat 4 and the roller 5 to move along the length direction of the telescopic rod 2. During the movement of the sliding seat 3, the spring 7 always pushes the roller 5 to contact the ceiling top, and the roller 5 rolls along the ceiling top, which can press the coil line against the ceiling top in turn, so that the coil line with ink marks the required positioning line on the ceiling top, thereby realizing marking on the ceiling of the curved roof.

[0037] When the top wall of the ceiling is flat, turn the first handle 17, and the first handle 17 drives the corresponding screw 10 to rotate, thereby driving the slider 9 to move downward, causing the roller 5 to slide in the direction away from the coil line and disengage from the coil line. Then tie the elastic rope to the middle position of the coil line, and then press an operating rod 1 against the ceiling. Then move the other operating rod 1 to press it against another point where the positioning line needs to be marked. The coil line with ink can be marked on the ceiling by pulling the elastic rope downward and then releasing it. The use status of the device can be adjusted according to actual needs, which expands the scope of application to a certain extent.

[0038] Reference Figure 1 and Figure 2 In order to facilitate the sliding of the sliding seat 3, the sliding assembly 6 includes a pull rope 61 fixedly connected to one side of the sliding seat 3 and a pulling member 62 arranged on the side of the sliding seat 3 away from the pull rope 61. A guide ring 8 for the pull rope 61 to slide through is fixedly installed on the slider 9 near the side of the pull rope 61. The end of the pull rope 61 away from the sliding seat 3 slides through the guide ring 8 and then hangs down naturally. The end of the pull rope 61 away from the sliding seat 3 is fixed with a pull ring 19 to facilitate pulling the pull rope 61. The pulling member 62 is used to pull the sliding seat 3 toward Sliding in the direction away from the guide ring 8, the telescopic rod 2 is fixedly connected to a fixed plate 20 on one side away from the guide ring 8, the fixed plate 20 is located on the side of the sliding seat 3 away from the guide ring 8, and the pulling member 62 includes a tension spring 621 for pulling the sliding seat 3 to slide in the direction away from the guide ring 8, one end of the tension spring 621 is fixedly connected to the side of the fixed plate 20 close to the guide ring 8, and the other end is fixedly connected to the side of the sliding seat 3 away from the guide ring 8, and the extension direction of the tension spring 621 is parallel to the length direction of the telescopic rod 2.

[0039] When the sliding seat 3 needs to be moved, the pull ring 19 is pulled downward, causing the pull ring 19 to pull the pull rope 61, which drives the sliding seat 3 to slide toward the guide ring 8. At this time, the tension spring 621 is stretched, and the guide ring 8 guides the sliding direction of the pull rope 61, which helps the sliding seat 3 drive the mounting seat 4 and the roller 5 to move, causing the roller 5 to roll along the ceiling, making it easier to fit the coil wire to the ceiling in sequence, and helping to mark the positioning line on the ceiling of the curved roof. When the sliding seat 3 needs to be moved away from the guide ring 8, the pull ring 19 is released. At this time, the tension spring 621 pulls the sliding seat 3 away from the guide ring 8, helping the sliding seat 3 to reset, determine the initial position of the sliding seat 3, and prevent the sliding seat 3 from sliding unnecessarily on the telescopic rod 2.

[0040] Reference Figure 3 A wire clamping ring 11 is provided on the drum 5, and the wire clamping ring 11 is arranged along the circumference of the drum 5. The longitudinal section of the wire clamping ring 11 is U-shaped, and the coil wire is located in the groove of the wire clamping ring 11. The wire clamping ring 11 is used to limit the coil wire. The distance from the side of the wire clamping ring 11 away from the drum 5 to the outer surface of the drum 5 is less than the diameter of the coil wire, so that the coil wire can abut against the inner wall of the ceiling when it is clamped in the wire clamping ring 11, thereby facilitating the continuous and smooth marking of the positioning line on the ceiling.

[0041] Reference Figure 2 and Figure 3 The bracket 12 is rotatably arranged on the mounting seat 4, and the rotation axis of the bracket 12 is parallel to the rotation axis of the drum 5. A rotating shaft 13 is coaxially fixed on the bracket 12, and the rotating shaft 13 rotates on the mounting seat 4. The mounting seat 4 is provided with an adjusting member 14 for adjusting the rotation of the bracket 12 and fixing it to a desired position. A connecting plate 21 is fixedly connected to the mounting seat 4. The adjusting member 14 includes a worm gear 141 fixedly mounted on the rotating shaft 13 and a worm 142 rotatably arranged on the connecting plate 21. The worm 142 is meshed with the worm gear 141, and one end of the worm 142 is fixedly connected to a second handle 22 to facilitate the rotation of the worm 142.

[0042] When it is necessary to adjust the angle between the roller 5 and the mounting base 4, the second handle 22 is rotated, and the second handle 22 drives the worm 142 to rotate, and the worm 142 drives the worm wheel 141 to rotate, so that the support plate 15 drives the roller 5 to rotate, so as to adjust the roller 5 to a suitable angle according to the curvature of the ceiling. Since the engagement between the worm wheel 141 and the worm 142 has a self-locking function, it is convenient to rotate and fix the bracket 12 to the desired position, so that the support plate 15 is not prone to unnecessary rotation during the contact between the roller 5 and the ceiling.

[0043] The implementation principle of the embodiment of the present application is as follows: when it is necessary to mark the positioning line of the ceiling of the curved top, according to the curvature of the ceiling, the second handle 22 is rotated, so that the second handle 22 drives the worm 142 to rotate, and the worm gear 141 drives the bracket 12 to rotate, and the roller 5 is adjusted to a certain angle with the mounting seat 4; then one operating rod 1 is pressed against the ceiling, and the other operating rod 1 is moved to press against another point of the positioning line that needs to be marked on the ceiling, and then the first handles 17 on both sides are rotated, and the first handles 17 drive the slider 9 to move to the required height, thereby adjusting the length and direction of the telescopic rod 2; so that the telescopic rod 2 2's telescopic direction is parallel to the direction of the line connecting the vertices of the operating rods 1 on both sides. At this time, the roller 5 is located below the coil wire and abuts against the ceiling, so that the spring 7 is in a compressed state; then the pull ring 19 is pulled downward, so that the pull rope 61 pulls the sliding seat 3 to slide in the direction close to the guide ring 8, and the tension spring 621 is stretched. During the movement of the sliding seat 3, the roller 5 rolls along the ceiling, and the spring 7 always pushes the roller 5 to abut against the ceiling, so that the roller 5 successively fits the coil wire on the ceiling, and the coil wire with ink marks the required positioning line on the ceiling, thereby realizing marking on the ceiling of the curved top.

[0044] When the top wall of the ceiling is flat, turn the first handle 17, and the first handle 17 drives the corresponding screw 10 to rotate, driving the slider 9 to move downward, so that the roller 5 is located below the coil line and separated from the coil line, and then tie the elastic rope to the middle position of the coil line, and then press one operating rod 1 against the ceiling, and move the other operating rod 1 to press it against another point on the positioning line that needs to be marked, and then pull the elastic rope downward to tighten it and then loosen it, so that the coil line with ink can be marked on the ceiling. The use status of the device can be adjusted according to actual needs, which expands the scope of application to a certain extent.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
