Abstract
Description
Technical Field
[0001] This utility model relates to an indoor installation auxiliary structure, specifically an adjustable-height indoor concealed equipment maintenance ceiling structure. Background Technology
[0002] In the field of interior decoration and equipment installation, suspended ceilings not only decorate interior spaces but are also frequently used to conceal various equipment such as air conditioning units, ventilation equipment, and electrical control cabinets, ensuring a clean and aesthetically pleasing indoor environment. However, existing suspended ceiling structures used to conceal equipment generally suffer from the following problems:
[0003] Poor maintenance convenience: Traditional ceilings are mostly fixed structures, requiring the disassembly of ceiling panels for equipment maintenance, which is cumbersome and easily damages the ceiling, resulting in low maintenance efficiency; some ceilings with access panels have limited access panel sizes, which cannot meet the overall maintenance needs of large equipment.
[0004] The height is not adjustable: the equipment is fixed in position after installation. If maintenance is required on the top or surrounding parts of the equipment, operators need to use climbing tools, which poses a safety hazard and limits the maintenance space.
[0005] Insufficient concealment and sealing: Gaps exist at the joints of some openable ceilings, which easily accumulate dust and leak air, affecting the cleanliness of the room; at the same time, the presence of gaps and access panels disrupts the integrity of the ceiling and affects the decorative effect.
[0006] Poor lifting stability: Some liftable ceilings use a single-sided drive or simple suspension structure, which is prone to tilting and jamming during lifting, and their reliability decreases after long-term use. Utility Model Content
[0007] The technical problem to be solved by this utility model is to provide an adjustable height indoor concealed equipment maintenance ceiling structure.
[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an adjustable height indoor concealed equipment maintenance ceiling structure, including a fixed ceiling plate, an adjustable lifting plate provided on the inner side of the fixed ceiling plate, an equipment body provided on the top of the lifting plate, first fixed mounting plates provided on both sides above the fixed ceiling plate, a first support plate provided at the bottom of each of the first fixed mounting plates, and a rotating shaft rotatably provided between the first support plates on the same side.
[0009] Both ends of the rotating shafts on both sides are equipped with steel wire ropes. The bottom of the steel wire ropes is fixedly connected to the four corners of the top of the lifting top plate. A drive motor that drives the rotating shaft on one side is provided on the outside of the first support plate. The ends of the rotating shafts on both sides away from the drive motor are provided with a common transmission structure.
[0010] Furthermore, the transmission structure includes an outer shell fixedly mounted on the first support plate, and transmission sprockets extending from the rotating shafts on both sides into the outer shell, with a transmission chain between the transmission sprockets on both sides.
[0011] Furthermore, the bottom of the lifting ceiling plate is provided with an auxiliary limiting plate, the lifting ceiling plate and the auxiliary limiting plate are convex, the fixed ceiling plate is provided with a square hole that matches the lifting ceiling plate, and the bottom of the fixed ceiling plate is provided with a square groove that matches the auxiliary limiting plate.
[0012] Furthermore, the auxiliary limiting plate is provided with limiting posts at the four corners of its top, and the square groove is provided with limiting slots that cooperate with the limiting posts at its top.
[0013] Furthermore, the top of the auxiliary limiting plate is provided with a sealing gasket on the outside of the lifting top plate.
[0014] Furthermore, a second fixed mounting plate is provided between the first fixed mounting plates at both ends on the same side, and a second support plate is provided at the bottom of the second fixed mounting plate, and the second support plate is provided with a bearing for connecting the rotating shaft.
[0015] Furthermore, the outer side of the rotating shaft is provided with a winding shell for cooperating with the steel wire rope, the winding shell is provided with a limiting winding space, and support rods are provided between the two sides of the winding shell and the first support plate and the second support plate.
[0016] Furthermore, a third fixed mounting plate is provided on the top of the main body of the equipment, a wire sleeve fixing frame is provided at the bottom of the third fixed mounting plate, and a telescopic wiring sleeve is provided between the main body of the equipment and the wire sleeve fixing frame.
[0017] Compared with the prior art, the advantages of this utility model are: adjustable height and convenient maintenance: through the cooperation of drive motor, transmission structure and steel wire rope, the lifting ceiling can be raised and lowered smoothly. The main body of the equipment can be lowered to a height that is easy to operate without disassembling the ceiling. This completely solves the problems of cumbersome maintenance and limited space in traditional ceilings, greatly improves maintenance efficiency and reduces operational risks.
[0018] Good concealment and strong sealing: The lifting ceiling and auxiliary limiting plate are convex in design, which can be precisely matched with the square holes and square grooves of the fixed ceiling. When the equipment is hidden, the limiting pin is inserted into the limiting slot, and the sealing gasket on the top of the auxiliary limiting plate fits tightly into the square groove. This not only ensures the integrity and decorative effect of the ceiling, but also effectively prevents dust and air leakage, and improves the cleanliness of the indoor environment.
[0019] Stable lifting and high reliability: The rotating shafts on both sides rotate synchronously with the transmission chain through the transmission sprocket, ensuring that the winding / unwinding speed of the steel wire ropes at the four corners is consistent and avoiding tilting of the lifting top plate; the bearings on the second support plate reduce the friction loss of the rotating shafts, and the limiting winding space of the winding shell can prevent the steel wire ropes from deviating or tangling, significantly improving the stability and service life of the structure.
[0020] Neat and Safe Wiring: The telescopic wiring sleeve between the main body of the equipment and the cable sleeve fixing frame can orderly constrain the wiring and avoid messy wiring. At the same time, the telescopic sleeve can freely extend and retract with the lifting of the top plate, ensuring that the wiring is not pulled or worn, which reduces safety hazards and facilitates wiring maintenance.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.
[0029] Combined with appendix Figure 1-6 An adjustable-height indoor concealed equipment access ceiling structure, the specific structure and implementation method of which are as follows:
[0030] I. Ceiling and Equipment Structure Assembly
[0031] The fixed ceiling plate 1 serves as the fixed base for the indoor ceiling. According to the indoor space dimensions and the specifications of the main body 11 of the equipment, a square hole 24 is opened in the middle of the fixed ceiling plate 1, and a square groove 19 is opened at the bottom of the fixed ceiling plate 1 at the position corresponding to the square hole 24. The size of the square groove 19 is adapted to the auxiliary limiting plate 20.
[0032] The lifting ceiling plate 2 is made of the same material as the fixed ceiling plate 1, and its size matches the square hole 24 (it can be slightly smaller in actual production) to ensure that there is no obvious shaking during the lifting process; the auxiliary limiting plate 20 is fixedly installed at the bottom of the lifting ceiling plate 2, so that the lifting ceiling plate 2 and the auxiliary limiting plate 20 form a convex structure, which improves the overall structural strength.
[0033] Weld or bolt the limiting pins 22 to the four corners of the top of the auxiliary limiting plate 20, and open the limiting slots 23 at the corresponding positions on the top of the square groove 19. The gap between the limiting pins 22 and the limiting slots 23 shall not exceed 0.5mm to ensure accurate positioning. A sealing gasket 21 shall be pasted on the area of the top of the auxiliary limiting plate 20 located outside the lifting top plate 2. The sealing gasket 21 shall be made of rubber and be 3-5mm thick to ensure a sealing effect when closed.
[0034] The main body 11 of the equipment is fixed to the preset installation position on the top of the lifting platform 2 with bolts. The center of gravity of the main body 11 coincides with the center of the lifting platform 2, so as to avoid tilting due to the shift of the center of gravity during the lifting process.
[0035] II. Lifting Drive Structure Assembly
[0036] The first fixed mounting plate 3 is fixed at both ends above the ceiling plate 1 using expansion bolts. The first fixed mounting plate 3 is made of steel plate with a thickness of not less than 8mm to ensure load-bearing capacity. The first support plate 4 is welded to the bottom of each first fixed mounting plate 3. The first support plate 4 is set perpendicular to the first fixed mounting plate 3, and the first support plates 4 at both ends on the same side are kept parallel.
[0037] A rotating shaft 5 is installed between the first support plates 4 on both sides of the same side. The rotating shaft 5 is made of stainless steel and the surface is treated with anti-rust. A winding groove is set at both ends of the rotating shaft 5 corresponding to the position of the steel wire rope 10 to ensure that the steel wire rope 10 is wound neatly.
[0038] One end of the wire rope 10 is fixed in the winding groove of the rotating shaft 5, and the other end is fixedly connected to the hanging rings at the four corners of the top of the lifting top plate 2. The diameter of the wire rope 10 is selected according to the total weight of the equipment body 11 and the lifting top plate 2, and the safety factor is not less than 5.
[0039] A drive motor 6 is fixed to the outside of one of the first support plates 4 by a motor bracket. The drive motor 6 is a stepper motor with forward and reverse rotation and self-locking functions. Its output shaft is connected to a rotating shaft 5 on one side through a coupling. A transmission structure 7 is installed at the end of the rotating shaft 5 on both sides away from the drive motor 6 to fix the outer shell 27 on the first support plate 4. A transmission sprocket 8 is installed on the part of the rotating shaft 5 on both sides that extends into the outer shell 27. A transmission chain 9 is sleeved between the two transmission sprockets 8. The tension of the transmission chain 9 is adjusted to ensure that the rotating shaft 5 on both sides rotates synchronously. Moreover, the winding direction of the steel wire rope 10 on both sides needs to be arranged synchronously according to the actual site layout.
[0040] III. Assembly of Auxiliary Limiting Support Structure
[0041] A second fixed mounting plate 12 is fixedly installed between the first fixed mounting plates 3 at both ends on the same side. The second fixed mounting plate 12 is set perpendicular to the first fixed mounting plate 3 to form a stable frame structure. A second support plate 13 is welded to the bottom of the second fixed mounting plate 12. The second support plate 13 is parallel to the first support plate 4 and its height is the same as that of the first support plate 4.
[0042] A bearing 14 is installed on the second support plate 13. The bearing 14 is a deep groove ball bearing, and its inner diameter is interference-fitted with the outer diameter of the rotating shaft 5 to reduce the frictional resistance when the rotating shaft 5 rotates. A winding shell 25 is sleeved on the outside of the rotating shaft 5. The size of the limiting winding space 26 inside the winding shell 25 is adapted to the winding radius of the wire rope 10 to prevent the wire rope 10 from coming off.
[0043] Support rods 15 are installed on both sides of the winding shell 25 between the first support plate 4 and the second support plate 13. The support rods 15 are made of steel pipe and are fixed at both ends by bolts. They serve to support the winding shell 25 and prevent the rotating shaft 5 from deforming due to concentrated force.
[0044] IV. Auxiliary wiring structure assembly
[0045] The third fixing plate 16 is fixed to the bottom of the building floor slab directly above the main body of the equipment 11 by expansion bolts. The position of the third fixing plate 16 is aligned with the center of the main body of the equipment 11. The top of the wire sleeve fixing bracket 17 is fixed to the bottom of the third fixing plate 16 by bolts. The wire sleeve fixing bracket 17 is provided with multiple wire holes for separating different types of wires.
[0046] One end of the telescopic wiring sleeve 18 is fixed in the wire hole of the wire sleeve fixing bracket 17, and the other end is connected to the junction box of the main body of the equipment 11. The telescopic wiring sleeve 18 is made of corrugated pipe material, and its telescopic range meets the maximum lifting stroke of the lifting top plate 2 (that is, in the actual wiring process, a long wiring is required to ensure the telescopic length), ensuring that the line is not pulled during the lifting process.
[0047] V. Usage Procedure
[0048] Hidden state: Drive motor 6 is self-locking, rotating shaft 5 remains stationary, steel wire rope 10 is in a tightened state, lifting top plate 2 is embedded in square hole 24 of fixed ceiling top plate 1, auxiliary limiting plate 20 fits square groove 19, limiting insert 22 is inserted into limiting slot 23, sealing gasket 21 is pressed and sealed. At this time, lifting top plate 2 and fixed ceiling top plate 1 form a complete plane, and the main body of equipment 11 is hidden inside the ceiling.
[0049] Maintenance status: Start the drive motor 6 to reverse, drive the rotating shaft 5 on one side to rotate, and through the cooperation of the transmission sprocket 8 and the transmission chain 9, the rotating shafts 5 on both sides reverse synchronously, the steel wire rope 10 is slowly released, and the lifting top plate 2 descends smoothly under the action of gravity, with the descent speed controlled at 50mm / s; when the lifting top plate 2 descends to the preset height (usually 1.8-2.2m from the ground), the drive motor 6 stops and self-locks, and the operator can carry out maintenance on the main body of the equipment 11.
[0050] Reset state: After maintenance is completed, start the drive motor 6 to rotate forward, and the two rotating shafts 5 rotate forward synchronously. The steel wire rope 10 is wound up, and the lifting top plate 2 rises smoothly. When the limit plug 22 is aligned with the limit slot 23 and inserted, the drive motor 6 stops, the sealing gasket 21 is pressed, and the hidden state is restored.
[0051] Working principle
[0052] This utility model provides power through a drive motor 6, which drives the rotating shaft 5 on one side to rotate. With the help of the transmission sprocket 8 and transmission chain 9 in the transmission structure 7, the rotating shafts 5 on both sides can rotate synchronously. When the rotating shaft 5 rotates, the steel wire rope 10 is wound or released, thereby driving the lifting top plate 2 and the main body of the equipment 11 to achieve lifting and lowering movement, so as to switch between equipment concealment and maintenance.
[0053] The cooperation between the limiting pin 22 and the limiting slot 23 ensures the positioning accuracy of the lifting ceiling 2 when it is closed, avoiding deviation; the sealing gasket 21 achieves a seal in the closed state, preventing dust from entering the ceiling; the bearing 14 on the second support plate 13 reduces the frictional loss of the rotating shaft 5; the limiting winding space 26 of the winding shell 25 avoids the entanglement and deviation of the steel wire rope 10, improving the lifting stability; the telescopic wiring sleeve 18 freely extends and retracts with the lifting ceiling 2, ensuring the safety and neatness of the wiring.
[0054] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
