Description

Technical Field

[0001] This utility model relates to the field of pipeline pre-embedded positioning technology, specifically a pipeline pre-embedded positioning spraying machine. Background Technology

[0002] In building electrical construction, to accurately fix the position of conduits, it is necessary to pre-mark positioning reference lines on the wall or ground to indicate the direction of the conduits. The most commonly used traditional tool is the chalk line. Although some improved chalk lines are equipped with telescopic poles to assist in working at heights, their core operation still relies on the traditional method of manually pulling and marking lines.

[0003] However, such tools exhibit significant limitations in actual single-person operation. When non-vertical (e.g., horizontal or diagonal) lines need to be drawn, the operator must first separate the ink marker from the telescopic pole, then brace the pole with their body for support, and finally hold the ink marker in one hand while using the other to draw the line. This process is cumbersome and extremely inconvenient, and the pole is prone to slipping or shifting during body movement, leading to inaccurate positioning. This not only severely affects the efficiency and accuracy of line drawing but may also cause wall contamination due to skewed lines or repeated drawing, failing to meet the refined requirements of efficiency and quality in modern construction.

[0004] Therefore, this utility model proposes a pre-embedded spray positioning spraying machine for pipelines. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-embedded positioning spraying machine for conduits to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a pre-embedded positioning spraying machine for conduits, including a telescopic rod, which includes a bottom rod, a middle rod, and a top rod. The bottom rod has an ink fountain for immersing the line on its side, and the line is pulled out from the ink fountain. The outer wall of the top rod has a fixing sleeve, and the end of the fixing sleeve has a connecting block. The side of the ink fountain and the side of the connecting block are on the same plane, and the side of the connecting block is fixedly connected to the line. The side of the middle rod has a snap-line mechanism for pulling the line away from the wall. The pre-embedded line for conduits can be positioned on the wall surface through the snap-line mechanism without disassembling the ink fountain.

[0006] Preferably, the elastic mechanism includes a connecting sleeve located on the outer wall of the middle rod, a fixed plate at the bottom of the connecting sleeve, a slide cylinder on the outer wall of the fixed plate, a slider at the bottom of the slide cylinder, the end of the slider being located directly below the line, and an electric push rod on the side of the fixed plate, with both ends of the electric push rod being fixedly connected to the fixed plate and the slide cylinder respectively.

[0007] Preferably, the slide cylinder is equipped with an electromagnet. When the electromagnet is energized in the forward direction, it generates a magnetic force that attracts the slider. When the electromagnet is energized in the reverse direction, it generates a repulsive force that repels the slider.

[0008] Preferably, both the electric actuator and the electromagnet are electrically connected to the control box on the ink fountain.

[0009] Preferably, the connecting block is equipped with a suspension rope inside, and a laser device is installed at the bottom end of the suspension rope. A disc is installed on the side of the ink fountain. When the telescopic rod is perpendicular to the ground, the laser beam emitted by the laser device is located at the center of the disc.

[0010] Preferably, a level is provided on the side of the base rod.

[0011] This utility model has at least the following beneficial effects:

[0012] In this invention, a telescopic rod structure is used to integrate the ink fountain into the side of the base rod. The ink line is fixed in place by the fixing sleeve and connecting block on the outer wall of the top rod. The line-spraying mechanism on the side of the middle rod, through the coordinated action of an electric push rod and an electromagnet, automatically completes the line stretching and ejection actions. This design overcomes the limitations of traditional ink fountains that require disassembly and separation, allowing a single person to complete vertical, horizontal, and diagonal positioning line spraying with the telescopic rod, significantly improving construction efficiency and positioning accuracy. Simultaneously, the laser instrument inside the connecting block and the level on the base rod form a dual calibration system, ensuring that the laser point is precisely aligned with the center of the disc on the side of the ink fountain when the telescopic rod is vertical. This further enhances the reliability of the positioning reference and effectively avoids rework caused by rod misalignment. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a pre-embedded spray positioning line spraying machine, including a telescopic rod 1, which includes a bottom rod 2, a middle rod 3, and a top rod 4. The top rod 4 can slide freely inside the middle rod 3, and the middle rod 3 can slide freely inside the bottom rod 2. The side of the bottom rod 2 is provided with an ink fountain 5 for dipping the line. The ink fountain 5 is connected to the bottom rod 2 by a buckle and can be disassembled. The line is pulled out from the ink fountain 5. The above belongs to the prior art and will not be described in detail.

[0021] The outer wall of the top rod 4 is equipped with a fixing sleeve 6 and is fixedly connected to it. The end of the fixing sleeve 6 is equipped with a connecting block 7 and is fixedly connected to it. The side of the ink fountain 5 and the side of the connecting block 7 are on the same plane, allowing workers to easily place the measuring tool on the side of the wall and prevent deviation during the marking process. The side of the connecting block 7 is fixedly connected to the wire. When the top rod 4 extends, it can pull the wire out of the ink fountain 5. The side of the middle rod 3 is equipped with a marking mechanism to pull the wire away from the wall. Without disassembling the ink fountain 5, the marking mechanism can be used to position the pre-embedded conduit on the wall. Operation is convenient and simple, effectively improving the accuracy of pre-embedded conduit positioning.

[0022] The elastic mechanism includes a connecting sleeve 8 located on the outer wall of the middle rod 3. The connecting sleeve 8 is fixedly connected to the middle rod 3. The bottom of the connecting sleeve 8 is provided with a fixing plate 9 and is fixedly connected to it. The outer wall of the fixing plate 9 is provided with a sliding cylinder 10 and is slidably connected to it. The bottom of the sliding cylinder 10 is provided with a slider 11 and is slidably connected to it. The end of the slider 11 is located directly below the line. The top of the slider 11 has a groove block for limiting the line, which can effectively increase the stability when stretching the line. The side of the fixing plate 9 is provided with an electric push rod 12. The two ends of the electric push rod 12 are fixedly connected to the fixing plate 9 and the sliding cylinder 10, respectively.

[0023] An electromagnet 13 is installed inside the slide cylinder 10 and fixedly connected to it. When the electromagnet 13 is energized in the forward direction, it generates a magnetic force that attracts the slider 11. When the electromagnet 13 is energized in the reverse direction, it generates a repulsive force that repels the slider 11. Both the electric push rod 12 and the electromagnet 13 are electrically connected to the control box on the ink fountain 5. The working state of the electric push rod 12 and the electromagnet 13 can be manually controlled by the operator, thereby driving the lifting of the slide cylinder 10 and the lateral displacement of the slider 11 within the slide cylinder 10.

[0024] In addition, a level 17 is fixedly connected to the side of the base rod 2. The level 17 can assist the staff in marking horizontal lines to ensure the levelness of the horizontal positioning line. A suspension rope 14 is fixedly connected to the inside of the connecting block 7. A laser device 15 is fixedly connected to the bottom end of the suspension rope 14. The suspension rope 14 will carry the laser device 15 freely, so that the laser device 15 always remains perpendicular to the ground. A disc 16 is fixedly connected to the side of the ink line 5. When the telescopic rod 1 is perpendicular to the ground, the laser beam emitted by the laser device 15 is located at the center of the disc 16. The point where the laser falls on the disc 16 can indicate to the staff whether the marked line is perpendicular to the ground, ensuring the accuracy of the positioning line.

[0025] Working principle:

[0026] When using the pre-embedded positioning line spraying machine for this conduit, first adjust the telescopic rod 1 to a suitable length to ensure that the relative positions of the top rod 4, middle rod 3, and bottom rod 2 meet the construction requirements. When marking the horizontal line, use the level 17 on the side of the bottom rod 2 to determine whether the telescopic rod 1 is horizontal; if vertical marking is required, use the laser instrument 15 and the disc 16 for calibration. When the laser point is located at the center of the disc 16, it indicates that the telescopic rod 1 is perpendicular to the ground. Subsequently, the top rod 4 drives the side of the connecting block 7 to pull the line out of the ink fountain 5. At this time, the line is in a ready-to-splash state. Simultaneously, the energizing direction of the electromagnet 13 is adjusted. When energized in the reverse direction, the electromagnet 13 pushes the slider 11 out of the slide cylinder 10, so that the slot at the end of the slider 11 supports the line. Then, the electric push rod 12 is activated through the control box. The electric push rod 12 pulls the slide cylinder 10 to slide along the fixed plate 9, moving the line away from the wall until the line is raised to a suitable height. Then, the energizing direction of the electromagnet 13 can be changed again, causing the slider 11 to retract into the slide cylinder 10, losing its limiting effect on the line. The line will then perform a snap-line operation on the wall surface under its own elastic force. It is worth noting that since the snap-line mechanism is located on the side of the top area of ​​the middle rod 3, when the telescopic rod 1 is extended, the snap-line mechanism will mostly be located in the center of the line. Stretching the center area of ​​the line is more conducive to improving the quality of the subsequent snap-line on the wall, making the snap-line clearer.

[0027] Compared to existing technologies, operators no longer need to disassemble the ink fountain 5 or manually pull the line; they can simply use the control box to complete the line-clamping action, significantly improving the convenience and positioning accuracy of single-person operation.
