Description

Technical Field

[0001] This utility model relates to the technical field of lifting control lighting fixtures, specifically to a lifting control mechanism and a lifting light using the mechanism. Background Technology

[0002] Lifting lighting fixtures are specifically designed for industrial and mining lighting, large sports facilities, and cultural venues requiring high illumination heights. Their advantages include reducing maintenance distance to ground level, saving significant maintenance costs and time, and ensuring the safety of maintenance personnel. They are particularly suitable for tall indoor factory buildings, such as power plants, airport / train station waiting halls, and hangars.

[0003] According to Chinese Patent No. CN208457730U, a cylindrical lifting lamp includes a lifting control mechanism, a lifting lighting mechanism, and a cylindrical body. The cylindrical body is provided with a partition, which divides the cylindrical body into an upper cylindrical body and a lower cylindrical body. The lifting control mechanism includes a master and slave reel and an electric lock body. The master and slave reels are each coaxially provided with a transmission wheel, and the two transmission wheels are connected by a belt or chain. The lifting lighting mechanism includes a guide plate, a latch, and a lighting component. The inner cavity formed by the lighting component and the guide plate is provided with a pulley system. A steel wire rope is provided, which passes through the partition, the upper surface of the guide plate, and around the pulley system, and its two ends are fixed to the master and slave reels respectively, thereby driving the lifting lighting mechanism to lift and lower. The lifting control mechanism and the lower lifting lighting mechanism are controllably connected by locking the latch and the electric lock body.

[0004] In the above scheme, a motor is used in conjunction with a belt and a drive wheel to drive two pulleys to rotate. However, this still has the following drawbacks: when the motor drives the two pulleys to rotate using the belt and drive wheel, the two traction ropes and the lamps may become asynchronous due to belt slippage, which reduces the stability of the lamps' lifting and lowering. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting control mechanism and a lifting lamp using the mechanism, so as to solve the problem that the two traction ropes and the lamp may not be raised and lowered synchronously due to belt slippage, which reduces the stability of the lamp's lifting and lowering.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a lifting control mechanism, including a housing, a dual-axis output motor is provided inside the housing, worm gears are respectively fixed on the two output shafts of the dual-axis output motor, two turbines are rotatably arranged inside the housing, the worm gears and turbines mesh with each other, a driving gear is fixed on one side of the turbine, two fixed columns are rotatably arranged inside the housing via bearings, a driven gear is fixedly sleeved on the fixed column, a winding wheel is fixedly sleeved on the fixed column, the driven gear meshes with the driving gear, and two traction ropes are fixed on the surface of the winding wheel.

[0007] Preferably, the dual-axis output motor is located in the middle of the housing, the angle between the axis of the dual-axis output motor and the inner top surface of the housing is 30 degrees, and the right end of the dual-axis output motor is inclined downward.

[0008] Preferably, the outer shell is fixed to the top surface of the mounting plate, and the top surface of the mounting plate has two cable outlets for the orderly delivery of the traction rope.

[0009] Preferably, a support column is fixed at each of the four corners of the bottom surface of the mounting plate, and a connecting plate is fixed between two adjacent support columns.

[0010] This utility model also discloses a lifting light, including a lifting plate and the lifting control mechanism, with a light tube arranged below the lifting plate.

[0011] Preferably, one end of the traction rope is fixed with an installation column, the top surface of the lifting plate is provided with a plurality of installation slots, the installation column is slidably disposed with the installation slots, two limiting plates are fixed on the surface of the installation column, and two limiting grooves are provided on the inner wall of the installation slots, the limiting plates are slidably disposed with the limiting grooves.

[0012] Compared with the prior art, the lifting control mechanism and the lifting light using the above technical solution have the following advantages:

[0013] 1. The two output shafts of the dual-axis output motor drive two worm gears respectively, and the worm gear drives two driven gears and winding wheels to rotate synchronously, so that the traction ropes on both sides can be wound and released synchronously. This effectively avoids the problem of inconsistent rope lengths on both sides caused by belt slippage in the existing technology, and improves the stability and structural integrity of the lamp during the lifting process.

[0014] Second, the dual-axis output motor is tilted relative to the housing, which makes better use of the space inside the housing, reduces interference between components, optimizes the spatial layout of the transmission structure, ensures efficient transmission and control functions within a limited space, and enhances the overall stability of the mechanism.

[0015] Third, the staff will first insert the mounting column into the mounting slot. After the mounting column is fully inserted into the mounting slot, the staff will rotate the mounting column clockwise to drive the limiting plate into the groove at the bottom of the limiting slot, thus fixing the traction rope to the lifting plate. Therefore, when the lamp tube is damaged, the staff can replace the lamp tube by disassembling the mounting column and the mounting slot, which increases the convenience of replacing the lamp tube.

Detailed Implementation

[0022] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figures 1-3As shown, a lifting control mechanism includes a housing 2, inside which a dual-axis output motor 4 is installed. Worms 5 are fixed to the two output shafts of the dual-axis output motor 4. Two turbines 6 are rotatably mounted inside the housing 2, with the worms 5 meshing with the turbines 6. A drive gear 27 is fixed to one side of each turbine 6. Two fixed posts 7 are rotatably mounted inside the housing 2 via bearings. A driven gear 8 is fixedly sleeved on each fixed post 7, and a winding wheel 9 is fixedly sleeved on each fixed post 7. The driven gear 8 meshes with the drive gear 27. Two traction ropes 10 are fixed to the surface of the winding wheel 9. The dual-axis output motor 4 is located in the middle of the housing 2. The angle between the axis of the dual-axis output motor 4 and the inner top surface of the housing 2 is 30 degrees, and the right end of the dual-axis output motor 4 is inclined downwards. The housing 2 is fixed to the top surface of a mounting plate 1. Two cable outlets 26 are provided on the top surface of the mounting plate 1 for the orderly delivery of the traction ropes 10. Support posts 24 are fixed at the four corners of the bottom surface of the mounting plate 1, and connecting plates 25 are fixed between adjacent support posts 24.

[0025] In use, the dual-axis output motor 4 rotates the output shaft, which drives the worm 5 to rotate synchronously. The rotating worm 5, through meshing with the turbine 6, drives the turbine 6 to rotate synchronously. During the rotation of the turbine 6, through meshing with the driven gear 8, drives the driven gear 8 and the winding wheel 9 to rotate, thereby realizing the release and retraction of the traction rope 10 at both ends of the outer casing 2.

[0026] By synchronously controlling the two output shafts of the dual-axis output motor 4 to rotate the two winding wheels 9 synchronously, the traction ropes 10 at both ends can be synchronously wound and released, which increases the stability of the two ends of the lamp when lifting and lowering the lamp. The dual-axis output motor 4 is set at an angle relative to the housing 2, which makes better use of the space inside the housing 2, reduces interference between components, optimizes the spatial layout of the transmission structure, ensures efficient transmission and control functions in a limited space, and enhances the overall stability of the mechanism.

[0027] Example 2

[0028] like Figure 2 and Figure 5 As shown, this utility model also discloses a lifting light, including a lifting plate 18, a light tube 19 is provided below the lifting plate 18, a mounting column 20 is fixed to one end of the traction rope 10, a plurality of mounting grooves 21 are provided on the top surface of the lifting plate 18, the mounting column 20 is slidably disposed with the mounting grooves 21, two limiting plates 22 are fixed on the surface of the mounting column 20, and two limiting grooves 23 are provided on the inner wall of the mounting grooves 21, the limiting plates 22 are slidably disposed with the limiting grooves 23.

[0029] During use, the operator first inserts the mounting post 20 into the mounting groove 21. After the mounting post 20 is fully inserted into the mounting groove 21, the operator rotates the mounting post 20 clockwise, causing the limiting plate 22 to slide into the groove at the bottom of the limiting groove 23, thus fixing the traction rope 10 to the lifting plate 18. Therefore, when the lamp tube 19 is damaged, the operator can replace the lamp tube 19 by disassembling the mounting post 20 and the mounting groove 21, which increases the convenience of replacing the lamp tube 19.
