Description

Technical Field

[0001] This invention relates to the field of interior decoration construction equipment technology, and in particular to an adjustable ceiling keel quick installation device for interior decoration. Background Technology

[0002] In interior decoration projects, ceiling installation is one of the core processes. Aluminum alloy keel is widely used in various interior ceiling projects due to its advantages such as light weight, high strength, corrosion resistance, and convenient installation. The current standard installation process for aluminum alloy keel is as follows: first, fix vertical hanging rods on the ceiling; then, fix the keel to the hanging rods using connectors; finally, level and fix the keel.

[0003] Existing technologies for installing and leveling ceiling joists suffer from the following drawbacks: adjusting the height and calibrating the level of the joists require repeated manual climbing of ladders by construction workers; installing a single joist necessitates multiple adjustments by climbing ladders, resulting in extremely low construction efficiency. Therefore, there is an urgent need to develop an adjustable ceiling joist rapid installation device for interior decoration. Summary of the Invention

[0004] In view of the above-mentioned problems, the purpose of this invention is to provide an adjustable ceiling keel quick installation device for interior decoration, which can be quickly snapped onto the hanging screw to realize the electric lifting and adjustment of the keel. With the help of infrared ranging and PLC control, it can ensure the height consistency of the hanging points on both sides and the levelness of the keel, improve the installation efficiency, and realize single-person single-machine operation.

[0005] This invention is achieved using the following technical solution: an adjustable ceiling keel quick installation device for interior decoration, comprising a pair of matching adjustment components, a pre-fixed hanging screw installed on the ceiling, and an aluminum alloy keel; The adjustment assembly includes a support frame, a hoisting frame, an adjustment frame, a drive assembly, a limit assembly, an infrared rangefinder, a lithium battery pack, and a PLC controller. The support frame is detachably mounted on the hoisting screw; the hoisting frame is rotatably mounted on the bottom end of the support frame; the adjusting frame is vertically mounted below the hoisting frame for hoisting with the aluminum alloy keel. The drive assembly is installed between the hoisting frame and the adjusting frame, and is used to drive the adjusting frame to move vertically up and down to adjust the hoisting height of the aluminum alloy keel; The limiting component is installed between the side wall of the hoisting frame and the adjusting frame to guide and limit the lifting and lowering movement of the adjusting frame; The infrared rangefinder is installed on the front side of the hoisting frame and is used to detect the vertical distance between the current hoisting point and the ceiling; The lithium battery pack is detachably mounted on the top of the support frame to provide power to the various electrical components of the equipment; The PLC controller is installed at the bottom of the support frame and is electrically connected to the drive assembly and the infrared rangefinder.

[0006] As a further improvement to the above solution, the support frame includes a main support plate and a secondary support plate; The main support plate has an L-shaped slot that matches the outer diameter of the hoisting screw. The main support plate is laterally engaged with the outer wall of the hoisting screw through the L-shaped slot. Two sets of connecting lugs are symmetrically welded to the bottom of the main support plate. One end of the secondary support plate is rotatably installed between the two sets of connecting lugs to adjust the angle between the main support plate and the secondary support plate. The other end of the secondary support plate is provided with a U-shaped groove that matches the outer diameter of the hoisting screw. The secondary support plate is engaged with the outer wall of the hoisting screw through the U-shaped groove. After the engagement is completed, a stable triangular support structure is formed between the main support plate, the secondary support plate and the hoisting screw.

[0007] As a further improvement to the above solution, a U-shaped groove is provided at the bottom of the main support plate, and two sets of lifting ear plates for hinged installation of the lifting frame are symmetrically welded below the U-shaped groove. The top of the main support plate is provided with a clamping assembly for quick and easy installation of the lithium battery pack, and the bottom of the main support plate is fixed with a mounting bracket for installing the PLC controller by bolts.

[0008] As a further improvement to the above solution, the hoisting frame includes a U-shaped bracket; the top two sides of the U-shaped bracket are hinged to the hoisting lugs by hinge bolts, and the U-shaped bracket can rotate freely around the axis of the hinge bolts; A bearing mounting sleeve is provided at the bottom center of the U-shaped bracket, and an adjusting bearing is installed in the inner cavity of the bearing mounting sleeve with an interference fit. A motor bracket for mounting the drive assembly is welded to the rear side of the U-shaped bracket, and a Y-shaped wire clamp for fixing the cable is installed on one side wall of the U-shaped bracket. The bottom front side of the U-shaped bracket is provided with a rangefinder mounting plate, and the rangefinder mounting plate has vertically opened mounting holes, in which the infrared rangefinder is vertically installed.

[0009] As a further improvement to the above solution, the adjustment frame includes an adjustment screw and a keel hanger; The top of the keel hanger is provided with a threaded sleeve that matches the external thread of the adjusting screw, and the bottom end of the adjusting screw is screwed into the inner cavity of the threaded sleeve. The top of the adjusting screw is horizontally fitted with a limit pin to limit the downward limit position of the adjusting screw.

[0010] As a further improvement to the above solution, the drive assembly includes a drive sleeve, a transmission bevel gear, a drive bevel gear, and a drive motor; The drive sleeve is vertically interference-fitted into the inner cavity of the adjusting bearing, and the drive sleeve can rotate synchronously with the inner ring of the adjusting bearing. The inner wall of the drive sleeve is provided with an internal thread that matches the external thread of the adjusting screw. The adjusting screw is vertically inserted into the inner cavity of the drive sleeve, and the two are driven by the engagement of the threads. The transmission bevel gear is mounted on the outer wall of the drive sleeve, and the two are connected by a flat key to achieve synchronous rotation. The drive motor is mounted on the rear side wall of the motor bracket, and the output shaft of the drive motor passes through the plate of the motor bracket. The drive bevel gear is mounted on the end of the output shaft of the drive motor, and the two are connected by a flat key to achieve synchronous rotation. The driving bevel gear and the transmission bevel gear mesh with each other to form a bevel gear transmission pair.

[0011] As a further improvement to the above solution, the limiting component includes a limiting plate, a gasket, and a limiting slider; The limiting plate is installed on the side wall of the hoisting frame, and the shim is placed between the contact surface of the limiting plate and the hoisting frame to adjust the installation gap; The side wall of the limiting plate is vertically provided with a limiting groove, the limiting slider is fixed to the side wall of the keel hanger, and the limiting slider is slidably embedded in the inner cavity of the limiting groove. When the adjusting frame moves up and down, the limiting slider slides vertically along the inner cavity of the limiting groove, restricting the circumferential rotation of the keel hanger and the adjusting screw.

[0012] As a further improvement to the above solution, the clamping assembly includes a Z-shaped clamping plate, an L-shaped clamping plate, a pressure plate, and a clamping spring; Both the Z-shaped and L-shaped clamps are symmetrically fixed to the top of the main support plate by bolts, and the distance between the Z-shaped and L-shaped clamps is greater than the overall length of the lithium battery pack. The clamping plate is arranged parallel to the side of the L-shaped clamping plate facing the Z-shaped clamping plate, and the clamping plate and the L-shaped clamping plate are fixedly connected by two sets of clamping springs of the same specification. When installing a lithium battery pack, one end is snapped into the groove of the Z-shaped clamping plate, while the other end is pressed and clamped laterally by the clamping plate under the elastic force of the clamping spring.

[0013] The beneficial effects of this invention are as follows: This invention utilizes a hinged adjustable structure between a main support plate and a secondary support plate. The main support plate has an L-shaped slot, and the secondary support plate has a U-shaped slot. This allows for direct snap-fit ​​fixation to the lifting screw without tools or disassembling the original nuts. After snap-fit, a stable triangular support structure is formed between the main support plate, the secondary support plate, and the lifting screw, providing a load-bearing foundation for the entire equipment. This enables quick tool-free assembly and disassembly of the equipment, solving the pain points of cumbersome installation and the need for drilling and welding fixation in traditional lifting brackets, and reducing the initial installation preparation time. This invention uses a decelerated stepper motor with a power-off self-locking function as a power source. The drive bevel gear and transmission bevel gear mesh with each other to drive the drive sleeve to rotate synchronously. Then, through the threaded transmission pair between the drive sleeve and the adjusting screw, the rotational motion is converted into the vertical linear lifting motion of the adjusting frame. The adjustment operation can be remotely controlled by an infrared remote controller to realize the electric adjustment of the keel hoisting height. There is no need for construction personnel to repeatedly climb ladders to manually tighten nuts for leveling. The entire installation process can be carried out by a single person and a single machine without the need for multiple people to cooperate. This invention uses a hinged connection between the bottom of the hoisting frame and the support frame. The hoisting frame can rotate freely around the hinge axis and can automatically align itself under gravity and always maintain a vertical state. It is not affected by the installation tilt of the support frame or the verticality deviation of the hoisting screw, and automatically eliminates the cumulative error caused by the installation tilt of the hoisting screw and the installation deviation of the support frame, without the need for manual calibration of verticality.

[0019] To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of known functions and known components are omitted.

[0020] like Figure 1-2 As shown in the figure, the present invention provides an adjustable ceiling keel quick installation device for interior decoration, which is used in pairs; before use, two parallel hanging screws 1 are pre-fixed vertically on the indoor ceiling, and two sets of adjustment components 3 are respectively clamped on the two hanging screws 1. The aluminum alloy keel 2 to be installed is horizontally suspended and fixed between the two sets of adjustment components 3. The installation and leveling of the aluminum alloy keel 2 are achieved by adjusting the two sets of adjustment components 3. like Figure 3-13 As shown, the adjustment component 3 is the core functional unit of the equipment, including a support frame 31, a hoisting frame 32, an adjustment frame 33, a drive component 34, a limit component 35, an infrared rangefinder 36, a lithium battery pack 37, and a PLC controller 38. Among them, the support frame 31 is the bearing foundation of the entire equipment. When in use, the support frame 31 is clamped on the hoisting screw 1, and the top of the support frame 31 is in contact with the ceiling of the room to limit the movement, providing stable vertical support for the equipment, so that the entire adjustment component 3 can be stably clamped on the hoisting screw 1, avoiding problems such as shaking and falling off during the hoisting process. like Figure 7-9 As shown, the support frame 31 includes a main support plate 311 and a secondary support plate 312, both of which are made of high-strength aluminum alloy sheet. An L-shaped slot 313 matching the outer diameter of the lifting screw 1 is provided on the main support plate 311. The horizontal slot of the L-shaped slot 313 passes through the side of the main support plate 311, and the vertical slot is coaxial with the lifting screw 1. During installation, the main support plate 311 can be quickly inserted into the lifting screw 1 through the horizontal slot, and then lowered to allow the lifting screw 1 to enter the vertical slot, thus completing the quick engagement of the main support plate 311. There is no need to remove the end nut of the lifting screw 1, which greatly improves the ease of installation. Two sets of connecting lugs 314 are symmetrically welded to the bottom of the main support plate 311, and hinge holes are coaxially opened on the two sets of connecting lugs 314. A connecting sleeve is welded to one end of the secondary support plate 312. The inner diameter of the connecting sleeve matches the diameter of the hinge hole. The connecting sleeve at the end of the secondary support plate 312 is installed between the two sets of connecting lugs 314 by a hinge bolt. The connecting sleeve can rotate freely around the axis of the hinge bolt, thereby flexibly adjusting the included angle between the main support plate 311 and the secondary support plate 312 to adapt to the needs of different installation scenarios. At the other end of the secondary support plate 312, a U-shaped slot 315 matching the outer diameter of the hoisting screw 1 is provided. The slot of the U-shaped slot 315 faces downward. During installation, it can be directly inserted upward into the outer wall of the hoisting screw 1 to form a two-point engagement with the main support plate 311. After engagement, a stable triangular support structure is formed between the main support plate 311, the secondary support plate 312 and the hoisting screw 1. Even when hoisting heavy-duty keel, it can ensure that the support frame 31 will not rotate or shift, greatly improving the installation stability of the equipment. A U-shaped groove is provided at the bottom of the main support plate 311. Two sets of lifting lugs 316 are symmetrically welded below the U-shaped groove. The two sets of lifting lugs 316 are coaxially provided with hinge holes for positioning and hinged installation of the lifting frame 32. A clamping assembly is provided at the top of the main support plate 311 for quick and detachable installation of the lithium battery pack 37. An L-shaped mounting bracket is fixed to the bottom of the main support plate 311 with bolts for fixed installation of the PLC controller 38 to prevent the PLC controller 38 from being damaged by construction collisions. The clamping assembly includes a Z-shaped clamping plate 371, an L-shaped clamping plate 372, a pressure plate 373, and a clamping spring 374. The Z-shaped clamping plate 371 and the L-shaped clamping plate 372 are symmetrically fixed to the top of the main support plate 311 with bolts, and the distance between the two is greater than the overall length of the lithium battery pack 37, leaving sufficient installation space. The pressure plate 373 is arranged parallel to the side of the L-shaped clamping plate 372 facing the Z-shaped clamping plate 371, and the pressure plate 373 and the L-shaped clamping plate 372 are welded and fixed together by two clamping springs 374 of the same specification. The two clamping springs 374 are symmetrically arranged to ensure uniform clamping force. When installing the lithium battery pack 37, first press the clamping plate 373 towards the L-shaped clamping plate 372 to compress the clamping spring 374. Then, clamp one end of the lithium battery pack 37 into the groove of the Z-shaped clamping plate 371. After releasing the clamping plate 373, under the rebound force of the clamping spring 374, the clamping plate 373 will laterally press and clamp the other end of the lithium battery pack 37, realizing tool-free quick clamping and fixing of the lithium battery pack 37. When disassembling, simply press the clamping plate 373 in the opposite direction to remove it, which greatly improves the efficiency of on-site battery replacement and meets the endurance requirements of long-term construction. like Figure 10-13As shown, the hoisting frame 32 is rotatably hinged to the bottom of the support frame 31. Specifically, the hoisting frame 32 includes a U-shaped bracket 321, which is made of U-shaped profile bent and welded, and has a strong structural rigidity. Hinges are provided at the top of both sides of the U-shaped bracket 321, and it is hinged to the hoisting ear plate 316 through hinge bolts. The U-shaped bracket 321 can rotate freely around the axis of the hinge bolt. Under the action of gravity, the U-shaped bracket 321 can automatically align and always be in a vertical state. Even if the support frame 31 tilts slightly due to installation error, it will not affect the verticality of the hoisting frame 32, which fundamentally ensures the vertical accuracy of the keel hoisting and avoids tilting of the keel installation. A bearing mounting sleeve 322 is welded and fixed at the bottom center of the U-shaped bracket 321. An adjusting bearing 323 is installed in the inner cavity of the bearing mounting sleeve 322 with an interference fit. The adjusting bearing 323 is a deep groove ball bearing, which takes into account both radial load capacity and rotational smoothness. An L-shaped motor bracket 324 is welded to the rear side of the U-shaped bracket 321 for fixing the drive assembly 34. A Y-shaped wire clamp 325 is fixed to one side wall of the U-shaped bracket 321 with bolts to clamp and fix the connecting cable between the infrared rangefinder 36 and the PLC controller 38, so as to avoid the cable shaking or tangling during equipment operation, which may cause interference or wire breakage. A rangefinder mounting plate 326 is welded to the bottom front side of the U-shaped bracket 321. The rangefinder mounting plate 326 has vertically opened mounting holes that match the housing of the infrared rangefinder 36. The infrared rangefinder 36 is vertically fixed in the mounting holes to ensure that its ranging transmitter is vertically facing the ceiling, thus ensuring the accuracy of the ranging data. The adjusting frame 33 is vertically installed below the hoisting frame 32 for hoisting and fixing the aluminum alloy keel 2. The adjusting frame 33 includes an adjusting screw 331 and a keel hanger 332. A threaded sleeve that matches the external thread of the adjusting screw 331 is welded to the top center of the keel hanger 332. The bottom end of the adjusting screw 331 is screwed into the inner cavity of the threaded sleeve. During on-site construction, the hoisting height can be pre-adjusted by manually screwing the adjusting screw 331 to adapt to different installation requirements. A limit pin is horizontally embedded at the top of the adjusting screw 331. The outer diameter of the limit pin is larger than the inner diameter of the drive sleeve 341. This limit pin is used to restrict the downward limit position of the adjusting screw 331 and prevent the adjusting screw 331 from coming out of the drive sleeve 341, thus avoiding the safety accident of the keel falling due to overtravel of the equipment. The drive assembly 34 is installed between the top of the adjustment frame 33 and the side of the hoisting frame 32 to drive the adjustment frame 33 to move up and down vertically, thereby adjusting the height of the aluminum alloy keel 2 during hoisting. The drive assembly 34 includes a drive sleeve 341, a transmission bevel gear 342, a drive bevel gear 343, and a drive motor 344. The drive sleeve 341 is vertically interference-fitted into the inner cavity of the adjusting bearing 323. The outer wall of the drive sleeve 341 is interference-fitted with the inner ring of the adjusting bearing 323, and can rotate freely synchronously with the inner ring of the adjusting bearing 323. The adjusting screw 331 is vertically inserted into the inner cavity of the drive sleeve 341, and the inner wall of the drive sleeve 341 is provided with an internal thread that matches the external thread of the adjusting screw 331. The two form a threaded transmission pair. When the drive sleeve 341 rotates, it can drive the adjusting screw 331 to move up and down vertically through the threaded transmission. The transmission bevel gear 342 is fixedly sleeved on the upper part of the outer wall of the drive sleeve 341. The two are connected by a flat key to achieve synchronous rotation and avoid slippage during transmission. The drive motor 344 is fixed to the rear side wall of the motor bracket 324 by bolts. The drive shaft of the drive motor 344 passes forward through the side wall of the motor bracket 324. The drive bevel gear 343 is fixedly sleeved on the end of the drive shaft of the drive motor 344. The two are connected by a flat key to achieve synchronous rotation. The drive bevel gear 343 and the transmission bevel gear 342 mesh with each other to form a bevel gear transmission pair, which can convert the horizontal rotation of the drive motor 344 into the vertical rotation of the drive sleeve 341, thereby realizing the conversion of the transmission direction. In this embodiment, the drive motor 344 is a geared stepper motor with self-locking function. Its reduction ratio can be selected according to the hoisting load requirements. After power failure, the output shaft can be mechanically self-locked to prevent the drive sleeve 341 from reversing under the gravity of the keel, which would cause the keel to fall and greatly improve the safety of equipment operation. At the same time, the stepper motor can be controlled by the PLC controller 38 to control its forward and reverse rotation, rotation angle and speed to adjust the hoisting height of the keel. The specific working process of the drive component 34 is as follows: When the infrared remote control inputs a command to the PLC controller 38 to rotate the drive motor 344 clockwise, the PLC controller 38 controls the drive motor 344 to start, driving the drive bevel gear 343 to rotate clockwise. Through meshing transmission, the drive bevel gear 342 and the drive sleeve 341 rotate synchronously. Under the threaded transmission action of the drive sleeve 341 and the adjusting screw 331, the adjusting screw 331 and the keel hanger 332 slide upward, thereby driving the aluminum alloy keel 2 on the keel hanger 332 to adjust its height upward. Conversely, when the PLC controller 38 controls the drive motor 344 to rotate counterclockwise, the adjusting screw 331 and the keel hanger 332 can slide downward, realizing the downward height adjustment of the aluminum alloy keel 2. During the hoisting and leveling operation of the aluminum alloy keel 2, the staff only needs to place the level on the top of the aluminum alloy keel 2 and control the rotation direction and rotation angle of the drive motors 344 of the two sets of adjustment components 3 separately or synchronously through the infrared remote control. This allows for the quick adjustment of the levelness and installation height of the aluminum alloy keel 2 without the need for staff to repeatedly climb ladders for manual adjustment, thus completely solving the problems of cumbersome and inefficient leveling in traditional installation methods. like Figure 5-6 As shown, the limiting component 35 is installed between the sides of the adjusting frame 33 and the hoisting frame 32 for guiding and limiting the vertical movement of the adjusting frame 33; wherein, the limiting component 35 includes a limiting plate 351, a gasket 352 and a limiting slider 354; The limiting plate 351 is fixed to the side wall of the U-shaped bracket 321 with bolts. A shim 352 is placed between the contact surfaces of the limiting plate 351 and the U-shaped bracket 321. The installation gap can be adjusted by increasing or decreasing the number of shims 352 to ensure the verticality of the limiting plate 351. The side wall of the limiting plate 351 is vertically provided with a limiting groove 353. The limiting groove 353 is a through groove, and its length matches the maximum lifting stroke of the adjusting frame 33. The limiting slider 354 is welded and fixed to the side wall of the keel hanger 332. The limiting slider 354 is slidably embedded in the inner cavity of the limiting groove 353. The outer wall of the limiting slider 354 and the inner wall of the limiting groove 353 are clearance-fitted to ensure smooth sliding while avoiding radial shaking. When the adjusting frame 33 moves up and down with the threaded transmission, the limiting slider 354 slides vertically synchronously along the inner cavity of the limiting groove 353, which can effectively limit the circumferential rotation of the keel hanger 332 and the adjusting screw 331, avoid the phenomenon of the adjusting screw 331 "following the rotation" during the threaded transmission, and ensure that the adjusting frame 33 can only move up and down in a straight line along the vertical direction, which greatly improves the stability of the lifting adjustment. An infrared rangefinder 36 is mounted on a rangefinder mounting plate 326 on the front side of the hoisting frame 32 to measure the vertical distance between the current installation position and the ceiling in real time, ensuring that the reference height of the two sets of adjustment components 3 is consistent with the hoisting height when they are installed on the hoisting screw 1. In this embodiment, the infrared rangefinder 36 adopts a high-precision laser rangefinder sensor with a measurement accuracy of ±0.1mm. It can transmit the detected distance data to the PLC controller 38 in real time and simultaneously transmit it to the matching infrared remote controller. The lithium battery pack 37 uses a large-capacity rechargeable lithium battery pack, which is installed on the clamping assembly at the top of the support frame 31 to provide working power for all electrical components such as the drive motor 344, infrared rangefinder 36, and PLC controller 38. The PLC controller 38 is mounted on the mounting bracket at the bottom of the support frame 31. The PLC controller 38 is equipped with an infrared receiver, which can receive control commands from the infrared remote control. At the same time, the PLC controller 38 is electrically connected to the drive motor 344 and the infrared rangefinder 36, respectively, and can realize the start, stop, forward and reverse control of the drive motor 344, as well as the reception and processing of the detection data of the infrared rangefinder 36. In this embodiment, the PLC controller 38 has a built-in data processing module, a synchronization control module and a storage module, and can receive distance detection data from the infrared rangefinders 36 on the two sets of adjustment components 3 in real time. The complete usage steps of this invention are as follows: Preliminary preparation: Pre-fix two vertical hanging screws 1 on the indoor ceiling at the designed spacing, and complete the verticality calibration of the hanging screws 1; Equipment installation: The support frames 31 of the two sets of adjustment components 3 are respectively clamped onto the two hoisting screws 1. First, the main support plate 311 is clamped into the hoisting screw 1 through the L-shaped slot 313. Then, the angle of the auxiliary support plate 312 is adjusted and the U-shaped slot 315 is clamped into the hoisting screw 1 so that the support frame 31 forms a stable triangular support structure, ensuring that the top of the support frame 31 is in close contact with the ceiling. Keel fixing: Place the aluminum alloy keel 2 to be installed horizontally at the bottom of the keel hanger 332 of the two sets of adjustment components 3, and fix the aluminum alloy keel 2 to the keel hanger 332 with bolts; Height adjustment and leveling: The PLC controller 38 receives real-time detection data from two sets of infrared rangefinders 36, which is used as the basis for adjusting the distance from the two side hanging frames 32 to the ceiling, so that the distance from the two side hanging frames 32 to the ceiling is the same; the aluminum alloy keel 2 is installed between the two keel hanging frames 332, the level is placed on the top of the aluminum alloy keel 2, and the control command is sent to the PLC controller 38 through the infrared remote control to start the drive motor 344 and adjust the overall hoisting height of the aluminum alloy keel 2 until the aluminum alloy keel 2 is in a horizontal state; Keel fixing and equipment disassembly: The leveled aluminum alloy keel 2 is fixedly connected to the lifting screw 1 through the matching connectors to complete the final installation of the keel; then the keel hanger 332 and aluminum alloy keel 2 are loosened, and the support frame 31 is removed from the lifting screw 1 to complete the entire installation operation.
