Description

Technical Field

[0001] This application relates to the field of ceiling installation technology, and in particular to a construction auxiliary device for large-area ceilings. Background Technology

[0002] A suspended ceiling refers to the decoration of the top of each floor of a house. It is very common in modern home decoration, providing appropriate decoration to the ceiling surface and also serving functions such as heat insulation, sound insulation, and heat preservation. When installing a suspended ceiling, it is necessary to first mark lines on the floor slab to assist in the positioning and installation of the ceiling's joists and structural panels. Currently, the marking method is mostly manual, using a tape measure to measure, position, and then manually mark the lines.

[0003] However, this marking method relies on manual positioning by workers. When installing large-area suspended ceilings, if the measuring tape is used for comparison or the marking line is slightly tilted, it is easy to produce large errors, resulting in the final installed components not being on a straight line. This leads to low construction efficiency and affects construction quality. Therefore, this application proposes a new technical solution. Summary of the Invention

[0004] To improve the construction quality and efficiency of large-area suspended ceiling installation, this application provides a construction auxiliary device for large-area suspended ceilings.

[0005] This application provides a construction auxiliary device for large-area suspended ceilings, employing the following technical solution:

[0006] A construction auxiliary device for large-area suspended ceilings includes a positioning mechanism for positioning and marking lines on the floor slab. The positioning mechanism includes a guide rail, a contact element, a fixed pen holder, and a laser detection unit for detecting whether the marking lines are offset. The guide rail has a groove along its length and a slider is slidably connected in the groove. The fixed pen holder is connected to the slider and extends out of the guide rail at both ends. The end of the fixed pen holder extending out of the guide rail has a mounting hole.

[0007] The contact element is mounted on the guide rail and abuts against the floor slab. The guide rail has a penetration hole for laser penetration. The laser detection unit is installed on the edge of the floor slab, and the penetration hole of the guide rail is located on the laser path of the laser detection unit.

[0008] Optionally, the fixed pen holder includes a fixed section and a distance adjustment section. The fixed section is fixed to the slider, and the distance adjustment section is slidably connected to the end of the fixed section away from the guide rail, with a mounting hole in the distance adjustment section. The fixed section is threadedly connected with a positioning bolt for abutting against the distance adjustment section.

[0009] Optionally, it also includes a rope for guiding the positioning mechanism to move in a preset direction and a fixing assembly for fixing and tightening the rope. The guide rail has a rope hole with parallel through holes, the rope passes through the rope hole, and both ends of the rope are connected to the fixing assembly.

[0010] The fixing components are used to connect with the embedded parts pre-installed on the floor slab. There are two sets of fixing components, which are symmetrically distributed. Each fixing component includes an abutment plate, a base plate, and an adjustment component. The abutment plate is L-shaped in side view, and one vertical section abuts against the wall. The end of the rope is detachably connected to the abutment plate. The section of the abutment plate perpendicular to the wall is slidably connected to the base plate. The base plate is equipped with an adjustment component for adjusting the sliding extension and contraction of the base plate. The manual adjustment end of the adjustment component extends out of the base plate. The top of the base plate is equipped with a clamp for fixing to the embedded parts.

[0011] Optionally, the adjustment assembly includes a screw, two bevel gears, and a rotating block. The screw is rotatably connected to the base plate and one end is threadedly connected to the abutment plate. One bevel gear is fixedly connected to the screw, and the other bevel gear is fixed with an extension shaft that rotates and extends out of the base plate. The rotating block is fixed to the end of the extension shaft that extends out of the base plate, and the two bevel gears mesh.

[0012] Optionally, the abutment plate is fixed with a tensioning assembly, which includes a second screw fixed to the abutment plate, a sleeve threaded to the second screw, and a pull ring rotatably connected to the sleeve, and the rope is fixed to the pull ring.

[0013] Optionally, it also includes a hook and a temporary fixing mechanism; the hook is fixed to the fixed pen holder and is used to hook the keel perpendicular to the rope;

[0014] The temporary fixing mechanism includes a connecting block, multiple hooks for suspending the keel, and a clamping assembly for positioning the end of the keel; the length of the connecting block is greater than that of the guide rail, the guide rail is slidably connected to the connecting block, and the multiple hooks are arrayed and fixed along the length direction of the connecting block.

[0015] Optionally, the clamping assembly includes two symmetrically arranged clamping blocks. The clamping blocks are C-shaped, with one end for connecting to the keel and the other end bypassing the guide rail. Grooves are opened on both sides of the keel, and a protrusion that fits into the groove is fixed at one end of the clamping block. A clamp is fixed at the other end of the clamping block for fixing the clamping block and the embedded part of the floor slab.

[0016] Optionally, it also includes a shielding assembly for intermittently blocking the rays of the laser detection unit. The shielding assembly is installed inside the guide rail and includes a shielding plate and a driving unit. The shielding plate is vertically slidably connected to the guide rail, and the sliding path intersects with the penetration hole. The driving unit is used to drive the shielding plate to rise and fall. The laser detection unit is wirelessly connected to a user terminal.

[0017] The drive unit includes a drive wheel, a drive gear, a driven gear, and a rocker arm rotatably connected to the guide rail. The surface of the drive wheel rests on the rope. The drive gear is coaxially fixed to the drive wheel. The driven gear is located above the drive gear and meshes with it. The rocker arm is eccentrically connected to the driven gear and the lower end of the rocker arm is hinged to the baffle plate.

[0018] Optionally, the abutment includes a support rod and a suction cup, the guide rail is fixed with an outwardly extending bottom rod, the support rod is fixed to the bottom rod and is vertical, and the suction cup is fixed to the upper end of the support rod.

[0019] Optionally, the support rod includes a lifting rod and a nut. The nut is fixed to the end of the base rod, and the lifting rod is threaded to the nut and vertically penetrates the base rod. A suction cup is fixed to the upper end of the lifting rod. A toothed ring is formed at the lower end of the nut. A synchronous belt is fitted onto multiple nuts. An end rod is vertically connected to the upper end of the lifting rod. The end rod penetrates the suction cup and has a top plate fixed to its upper end. A vent hole is provided at the bottom of the suction cup. A return spring is fitted onto the lower end of the end rod. In its natural state, the return spring drives the top plate to extend out of the suction cup.

[0020] In summary, this application includes the following beneficial technical effects: laser penetration observation replaces the original process of measuring tape comparison to check for accurate positioning, which is more convenient and faster. Furthermore, laser penetration reduces errors caused by hand tremors or visual misjudgment compared to manual measurement. By opening a groove and installing a slider within the guide rail, and fixing the pen holder to the slider, the positioning line can be quickly and easily drawn along the groove direction when marking lines. This eliminates the need for manual pressing of the long ruler for marking, avoiding errors caused by partial offset during ruler pressing. This results in more accurate positioning lines, improves the precision of subsequent end component installation, and further enhances the construction quality of large-area suspended ceiling installations.

[0028] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0029] This application discloses a construction auxiliary device for large-area suspended ceilings.

[0030] Reference Figure 1 The construction auxiliary device applied to large-area suspended ceilings includes a positioning mechanism 1 for marking lines on the floor slab. The positioning mechanism 1 includes a guide rail 11, an abutment 12, a fixed pen holder 13, and a laser detection unit for detecting whether the marking line is offset. The guide rail 11 is cuboid in shape, and a groove is provided inside the guide rail 11 along its length. In this embodiment, the groove can be located at the bottom and open downwards. A slider is slidably connected inside the groove (to prevent the slider from falling downwards, the width of the bottom of the groove is greater than the width of the opening, and the shape of the slider matches the shape of the groove, such as an inverted convex shape). The fixed pen holder 13 is connected (e.g., fixed by bolts and nuts) to the bottom of the slider. In this embodiment, the fixed pen holder 13 is located below the guide rail 11, and both ends of the fixed pen holder 13 are greater than the width of the guide rail 11. The end of the fixed pen holder 13 away from the guide rail 11 has an installation hole for fixing the marking pen. After the marking pen is inserted into the installation hole, it can be fixed by clamps or wire wrapping.

[0031] The abutting parts 12 are installed on multiple corners of the guide rail 11 and are used to abut against the floor slab, thereby temporarily fixing and positioning the guide rail 11 and the floor slab, making it convenient to use the guide rail 11 for marking.

[0032] The laser detection unit is installed on the edge of the floor slab with the laser emitting end facing the guide rail 11. The guide rail 11 has a penetration hole along its length for the laser to pass through. The laser beam passes through the penetration hole. By observing whether the laser beam is blocked, it can be determined whether the positioning mechanism 1 is offset.

[0033] With the above settings, a slide groove is opened in the guide rail 11 and a slider is set. The fixed pen holder 13 is fixed to the slider. When drawing lines, pushing the slider and the fixed pen holder 13 can quickly and easily draw the positioning line along the opening direction of the slide groove. The laser penetration observation to see if it is blocked replaces the original process of comparing and observing whether the positioning is accurate with the measuring tape, which is more convenient and faster. Moreover, the laser penetration reduces the error caused by hand tremors or visual judgment errors compared with manual use of measuring tape.

[0034] When the laser passes through the penetration hole, the slider is directly slid to draw the line, eliminating the need for manual pressing of the long ruler. This avoids errors caused by partial offset when the long ruler is pressed, making the positioning line more accurate and improving the accuracy of the subsequent installation position of the end components, thus further improving the construction quality of large-area suspended ceiling installation.

[0035] Considering the differences in ceiling sizes, and given that the length of the fixed pen holder 13 extending from the guide rail 11 is fixed, it would be cumbersome to replace it with a different size fixed pen holder 13 when changing construction sites to accommodate ceilings of different sizes. Therefore, the following settings are made:

[0036] Reference Figure 1 and Figure 2 The fixed pen holder 13 includes a fixed section 131 and a distance adjustment section 132. The fixed section 131 may be welded to the slider. The fixed section 131 has a sliding groove inside, and the sliding groove opens in the direction away from the guide rail 11. The distance adjustment section 132 is slidably connected to the end of the fixed section 131 away from the guide rail 11. The mounting hole is opened in the distance adjustment section 132. The fixed section 131 is threadedly connected to a positioning bolt 133 for abutting against the distance adjustment section 132. After adjusting the extension length of the distance adjustment section 132, the positioning bolt 133 is tightened to limit the extension length of the distance adjustment section 132 while fixing it.

[0037] Considering that the above-mentioned setup still requires manual movement when using the mobile positioning mechanism 1, and then comparing whether the laser detection unit's rays pass through the penetration hole to determine whether the positioning is accurate after movement is quite cumbersome, and relying solely on the contact member 12 to contact the floor slab may pose a risk of loosening, the following setup is made:

[0038] In another embodiment of this application:

[0039] Reference Figure 3This application also includes a rope 2 for guiding the positioning mechanism 1 to move in a preset direction, and a fixing component 3 for fixing and tightening the rope 2. The guide rail 11 has a rope hole with parallel through holes (the rope hole can be located at the center of the guide rail 11). The rope 2 passes through the rope hole, and both ends of the rope 2 are tied and fixed to the fixing component 3. By passing the rope 2 through the guide rail 11, after a positioning line is drawn, the abutment 12 can be released, allowing the guide rail 11 to move along the rope 2.

[0040] First, due to the installation of the rope 2, it is only necessary to adjust the guide rail 11 to a state where the laser beam of the laser detection unit can pass through the penetration hole when fixing the guide rail 11 for the first time, and to make the rope 2 and the beam parallel. After that, it can be moved along the rope 2 without repeatedly adjusting the angle of the guide rail 11.

[0041] Secondly, the rope 2 passes through the guide rail 11, which also plays a certain role in fixing and supporting the guide rail 11, reducing the risk of the contact part 12 coming loose, and greatly avoiding the risk of the guide rail 11 falling after the contact part 12 comes loose. In addition, when moving the guide rail 11, pushing the guide rail 11 along the rope 2 can eliminate the need for manual support of the guide rail 11, making it more labor-saving to use.

[0042] Since the rope 2 is threaded through the center of the guide rail 11 in this application, the guide rail 11 is prone to tilting left and right along the position where the rope 2 is threaded. The abutment 12 in this application, while abutting against the floor slab, can temporarily fix the guide rail 11 and prevent it from tilting left and right. In one embodiment of this application, the abutment 12 includes a support rod 121 and a suction cup 122. The guide rail 11 is fixed with an outwardly extending bottom rod 14. The support rod 121 is fixed (e.g., welded or bolted and nut fixed) to the bottom rod 14 and is arranged vertically. The suction cup 122 is fixed to the upper end of the support rod 121. By adsorbing onto the floor slab through the suction cup 122, it plays a certain role in temporarily fixing the guide rail 11. In conjunction with the rope 2, it can be used to maintain the balance of the guide rail 11, reduce its left and right tilting, and make the fixation and support of the guide rail 11 more stable.

[0043] Since the floor slab is not always perfectly flat, relying solely on the suction of suction cup 122 for fixation may not be very secure. Therefore, the following setup is implemented:

[0044] In another embodiment of this application:

[0045] Reference Figure 3 and Figure 4The support rod 121 includes a lifting rod 1211 and a nut 1212. The nut 1212 is fixed to the end of the base rod 14. The lifting rod 1211 is threaded to the nut 1212 and vertically penetrates the base rod 14. The lifting rod 1211 is raised and lowered by rotating the nut 1212. The upper end of the lifting rod 1211 is fixed with a suction cup 122. The base rod 14 is fixed downward with an annular frame for supporting the nut 1212. The top of the nut 1212 is integrally formed with an annular plate facing outward. The annular plate abuts against the upper surface of the annular frame, thereby supporting the nut 1212 and even the lifting rod 1211 while ensuring that the nut 1212 can rotate normally.

[0046] The end of the lifting rod 1211 that is in contact with the bottom rod 14 is set as a rectangle. The bottom rod 14 has a rectangular through hole. So, while the nut 1212 rotates, the rectangular shape restricts the rotation of the lifting rod 1211, so that the lifting rod 1211 will only move up and down and will not rotate when the nut 1212 is turned.

[0047] The lower end of the nut 1212 is formed with a toothed ring, and multiple lifting rods 1211 are fitted with a timing belt (not shown in the figure). The inner side wall of the timing belt can be provided with a toothed structure that meshes with the toothed ring. The timing belt links multiple nut 1212, so that when one nut 1212 is turned, the other multiple nut 1212 can be rotated at the same time, thereby driving multiple lifting rods 1211 to rise and fall simultaneously.

[0048] The upper end of the lifting rod 1211 is vertically connected to the end rod 1213. The end rod 1213 penetrates the suction cup 122 and the upper end is fixed to the top plate 1214. The bottom of the suction cup 122 is provided with a vent hole. When the suction cup 122 is attached to the floor slab, the top plate 1214 abuts against the bottom of the suction cup 122 and blocks the vent hole. The lower end of the end rod 1213 is fitted with a return spring 1215. In its natural state, the return spring 1215 drives the top plate 1214 to extend out of the suction cup 122. The end rod 1213 may be integrally formed with a ring plate. The lifting rod 1211 is hollow inside and the part near the end rod 1213 is provided with a fixed ring block for the end rod 1213 to slide up and down. The fixed ring block and the lifting rod 1211 are fixed (e.g., integrally formed). The end rod 1213 is slidably connected to the fixed ring block. The two ends of the return spring 1215 are respectively fixed to the ring plate and the fixed ring block.

[0049] With the above setup, rotating the nut 1212 causes the lifting rod 1211 to push the suction cup 122 upward, thereby adhering to the floor slab. As the lifting rod 1211 rises, the top plate 1214 abuts against the floor slab, gradually compressing the return spring 1215 until the top plate 1214 abuts against the bottom of the suction cup 122, blocking the vent hole. At this time, the suction cup 122 also adheres to the floor slab, thus playing a fixing role. When it is necessary to move the guide rail 11, rotating the nut 1212 causes the lifting rod 1211 to descend. Under the action of the return spring 1215, the top plate 1214 is pushed out, causing the top plate 1214 to separate from the bottom of the suction cup 122. The suction cup 122 takes in air through the vent hole and is successfully released.

[0050] This setup makes adsorption and detachment easier, and by linking multiple nuts 1212 together, rotating just one nut 1212 can drive the others, making it more efficient and convenient to use.

[0051] To ensure that rope 2 is more securely fixed to the floor slab or wall, the following setup is made:

[0052] Reference Figure 2 and Figure 5 Since the floor slab has pre-embedded parts, this application connects the fixing component 3 to the pre-embedded parts near the edge of the floor slab. The fixing component 3 consists of two sets and is symmetrically installed on the two opposite edges of the floor slab.

[0053] The fixing component 3 includes an abutment plate 31, a base plate 32, and an adjustment component 33. The abutment plate 31 is L-shaped in side view and its vertical section abuts against the wall. The end of the rope 2 is detachably connected to the abutment plate 31 (e.g., the abutment plate 31 is provided with a ring, and the rope 2 is tied to the ring). The base plate 32 has a cavity that opens towards the abutment plate 31. The section of the abutment plate 31 perpendicular to the wall (i.e., the horizontal section) is slidably connected to the base plate 32.

[0054] An adjustment component 33 for adjusting the sliding and telescopic amount of the substrate 32 is installed inside the substrate 32. The manual adjustment end of the adjustment component 33 extends out of the substrate 32. The telescopic amount of the abutment plate 31 in the substrate 32 is adjusted by the manual adjustment end to control the overall length of the abutment plate 31 and the substrate 32. A clamp 34 for fixing to the embedded part is installed (e.g., welded) on the top of the substrate 31. The clamp 34 can be half of a complete clamp. The substrate 42 and the embedded part are fixed by abutting the clamp 34 against the embedded part and then splicing and fixing the other half of the clamp to the clamp 34.

[0055] Since the distance between the embedded part and the wall panel is not fixed, an adjustment component 33 is provided to adjust the total length of the base plate 32 and the abutment plate 31. Before installation, the adjustment component 33 is used to adjust the abutment plate 31 to extend or insert into the base plate 32, so that the abutment plate 31 is close to or abuts against the wall panel, and at the same time, the clamp 34 can be fixed to the embedded part. After installation, the adjustment component 33 can be used for fine adjustment to make the abutment plate 31 more firmly abut against the ground, thereby improving the stability of the installation of the fixing component 3 and improving the fixing and even support effect on the rope 2 and the guide rail 11.

[0056] The adjustment assembly 33 includes a screw 331, two bevel gears 332, and a rotating block 333. One bevel gear 332 is fixedly connected to the screw 331, and a section of the screw 331 may extend outward and be welded to the bevel gear 332. The other bevel gear 332 has an extension shaft fixed at its center, and the extension shaft extends out of the base plate 32. The rotating block 333 is fixed to the end of the bevel gear 332 that extends out of the base plate 32, and the two bevel gears 332 mesh. With the above configuration, the amount of expansion and contraction of the abutment plate 31 within the base plate 32 can be adjusted by turning the rotating block 333, thereby making the base plate 32 fit more tightly against the wall panel. This adjustment method is convenient and easy to use.

[0057] If rope 2 is not taut, its middle section may sag, so the following settings should be made:

[0058] Reference Figure 3 and Figure 5 In another embodiment of this application, the abutment plate 31 is fixed with a tensioning assembly 34 for tightening the rope 2. The tensioning assembly 34 includes a screw 341 fixed (e.g., welded) to the abutment plate 41, a sleeve 342 threaded to the screw 341, and a pull ring 343 rotatably connected to the sleeve 342. The pull ring 343 can extend into a round rod that inserts into the sleeve 342, and the end of the round rod inserted into the sleeve 342 has an annular piece integrally formed outward, thereby confining the round rod within the sleeve 342 and rotatably connecting it to the sleeve 342. When it is necessary to adjust the tension of the rope 2, the sleeve 342 is rotated, causing the screw 341 to extend or retract within the sleeve 342. Rotating the sleeve 342 does not cause the pull ring 343 or the rope 2 to rotate, making this configuration more convenient to use.

[0059] The guide rail 11 is designed to assist in the transportation and installation of the keel during the marking and movement process, therefore the following settings are made:

[0060] In another embodiment of this application:

[0061] There are at least two sets of construction auxiliary devices, which are symmetrically arranged. The two sets of construction auxiliary devices are used to fix the two ends of the keel and maintain the balance of the keel. Since the keel includes both longitudinal and transverse directions, it is fixed and installed separately. This application is used to assist in the transportation and installation of the keel in one direction (this application takes the transverse direction as an example).

[0062] Reference Figure 3 This application also includes multiple hooks 4 and a temporary fixing mechanism 5, wherein the hooks 4 are fixed (e.g., suspended by rope) to the fixed pen holder 13 (which may be the distance adjustment section 132 fixed to the fixed pen holder 13) and are used to hook and transport the keel perpendicular to the rope 2 (i.e., laterally). The top of the keel is provided with multiple rings along its length for the hooks 4 to hook.

[0063] The temporary fixing mechanism 5 is used to temporarily fix the longitudinal keel. Workers can first lift the longitudinal keel and fix it to the temporary fixing mechanism 5. The temporary fixing mechanism 5 includes a connecting block 51, multiple hooks 52 for suspending the keel, and a clamping assembly 53 for positioning the ends of the keel. The length of the connecting block 51 is greater than the length of the guide rail 11, and the connecting block 51 can be located in the middle of the construction area. The distance between the two ends of the connecting block 51 and the wall panel is less than the length of the guide rail 11. A sliding groove is opened at the bottom of the guide rail 11 so that the guide rail 11 can slide and connect to the connecting block 51. In order to prevent the connecting block 51 from falling off, the top of the connecting block 51 extends to both sides with limiting sections, and the shape of the sliding groove matches the shape of the connecting block 51.

[0064] Multiple hooks 52 are arranged in an array and fixed along the length of the connecting block 51. The fixing method of hooks 52 is the same as that of hook 4. Hooks 52 are used to hook the longitudinal keel. In order to facilitate the pushing of the guide rail 11, the guide rail 11 can be fixed with a hand rope for pulling the guide rail 11. For example, the bottom of the guide rail 11 is provided with a ring, and the ring is used to tie the hand rope. The worker pulls the guide rail 11 forward by the hand rope to draw lines.

[0065] With the above configuration, the guide rail 11 can simultaneously transport the horizontal keels to designated positions for worker installation while marking lines. The vertical keels are temporarily fixed in place beforehand and installed after marking. This application offers richer functionality and greater ease of use, transporting and installing keels simultaneously with marking lines, significantly improving construction efficiency.

[0066] Considering that relying solely on hook 2 52 to hold the keel may cause swaying and instability, a clamping assembly 53 is provided to fix both ends of the keel. The clamping assembly 53 includes two symmetrically arranged clamping blocks 531. The clamping blocks 531 are C-shaped when viewed from the side, with one end used to connect to the keel and the other end bypassing the guide rail 11.

[0067] The keel has grooves on both sides and one end (i.e., the lower end) of the clamping block 531 is fixed (e.g., integrally formed) with a protrusion that fits into the groove, so that the clamping block 531 can slide into the end of the keel and clamp the keel to fix it, reducing the risk of the keel loosening and falling. The other end (i.e., the upper end) of the clamping block 531 is fixed (e.g., threaded connection or welding) with a clamping hoop 532 for fixing the clamping block 531 and the embedded part of the floor slab. When the two clamping blocks 531 are spliced, the clamping hoop 532 is sleeved on the outside of the embedded part. At this time, the clamping hoop 532 is locked and fixed, thereby fixing the clamping block 531 and the embedded part. At the same time, both ends of the keel are also fixed. In this application, the upper part of the clamping block 531 has a hole for the embedded part to pass through along the inner wall of the clamping hoop 532.

[0068] The above setup can further secure the vertical keel, allowing it to rely not only on the force of hook 252 but also on the force of the embedded parts for stability, thus reducing the risk of the keel becoming loose and falling.

[0069] Since the installation of horizontal keels and the marking of lines may require additional positioning of individual points, relying on manual measurement of the spacing between the keels or positioning points may be prone to errors and require multiple measurements, which is inconvenient. Therefore, the following settings are made:

[0070] In another embodiment of this application:

[0071] Reference Figure 6 This application also includes a shielding component 6 for intermittently blocking the rays of the laser detection unit. The shielding component 6 is installed inside the guide rail 11. The guide rail 11 may have a mounting groove for installing the shielding component 6. The shielding component 6 includes a shielding plate 61 and a driving unit 62. The shielding plate 61 is vertically slidably connected to the guide rail 11, and the sliding path intersects with the penetration hole, thereby blocking the rays of the laser detection unit.

[0072] The drive unit 62 is used to drive the baffle 61 to rise and fall, and the laser detection unit (which may be a laser range sensor) is wirelessly connected to the user terminal (such as a mobile phone) via a Bluetooth module.

[0073] With the above settings, the shield 61 blocks the rays of the laser detection unit. The laser detection unit feeds back the distance from the installation position to the shield 61, which is the current moving distance of the guide rail 11. The user receives the current moving distance through his mobile phone. This is more accurate and less labor-intensive than manual distance detection, improving the quality of ceiling installation while increasing construction efficiency.

[0074] The drive unit 62 includes a drive wheel 621 rotatably connected to the guide rail 11, a drive gear 622, a driven gear 623, and a rocker arm 624. The drive wheel 621 can be an H-beam wheel. The wheel surface of the recessed part in the middle of the drive wheel 621 rests on the rope 2. When the guide rail 11 is moved by pulling the rope, the drive wheel 621 rotates. The drive gear 622 is coaxially fixed to the drive wheel 621, and the driven gear 623 is located above the drive gear 622 and meshes with it, thereby driving the drive gear 622. The rocker arm 624 rotates together with the driven gear 623. It is eccentrically mounted on the driven gear 623 and rotatably connected to the driven gear 623. The lower end of the rocker arm 624 is hinged to the baffle plate 61. The guide rail 11 has a lifting groove for the baffle plate 61 to move vertically up and down. When the driven gear 623 drives the rocker arm 624 to rotate, the height of the rocker arm 624 will change, thereby driving the baffle plate 61 to move up and down in the lifting groove, thus intermittently blocking the rays of the laser detection unit.

[0075] With the above settings, the shielding plate 61 can be raised and lowered while the guide rail 11 moves, successfully achieving the effect of intermittently blocking rays, making it more convenient to use.

[0076] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
