Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and in particular relates to a lifting lamp. Background Art

[0002] Lifting lamps are specially designed for industrial and mining lighting, large sports facilities, cultural venues, large supermarkets, stations and docks with high lighting heights. Their advantage is that they turn the high-altitude cleaning and maintenance of lighting lamps into ground operations, saving a lot of maintenance costs and time, and ensuring the safety of maintenance personnel. Existing lifting lamps generally use motors to drive the wire reel to rotate, thereby reeling in or releasing the wire rope to achieve the lifting function of the high-altitude lamps. The stability is poor. When the weight of the lamp exceeds the load-bearing range of the lifter, or when the motor fails, it may cause the wire reel to rotate uncontrollably and release the wire rope, resulting in an accident where the high-altitude lamp falls.

Both ends of the flexible rope 3 are fixed to the towing assembly 5. The flexible rope 3 passes through the first threading hole 27, and the middle part of the flexible rope is passed through the guide member 4. The towing assembly 5 is arranged on the mounting plate 1 and is used to wind or release the flexible rope 3.

[0028] A guiding mechanism for guiding the flexible rope 3 is provided obliquely above the towing assembly 5;

[0029] Self-locking mechanism: a self-locking mechanism cooperating with the flexible rope 3 is provided on the mounting plate 1 .

[0030] It can be seen from the present embodiment that the flexible rope 3 controls the lifting and lowering of the lamp 2 by passing through the guide member 4. The towing assembly 5 arranged on the mounting plate 1 is used to slowly lower the lamp 2 during the process of slowly releasing the flexible rope 3. Conversely, the winding flexible rope 3 is used to lift and reset the lamp 2. The setting of the guiding mechanism can ensure that the flexible rope 3 maintains a guiding effect in the vertical direction during operation. When the weight of the lamp exceeds the load-bearing range or the motor fails, the lamp 2 will drive the flexible rope 3 to slide down sharply. Through the self-locking mechanism, the flexible rope 3 can be locked when the lamp 2 slides down sharply to avoid danger.

[0031] Embodiment 2:

[0032] This embodiment provides a lifting lamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0033] The towing assembly 5 comprises:

[0034] A first support plate 6, two first support plates 6 are symmetrically arranged on the top of the mounting plate 1;

[0035] A winding wheel 7 is rotatably connected between the two first support plates 6, and wire grooves 8 are provided on both sides of the winding wheel 7, and the flexible rope 3 is wound on the wire grooves 8;

[0036] The winding motor 9 is fixedly mounted on one end of a first support plate 6 , and the output shaft of the winding motor 9 passes through the first support plate 6 and is fixedly connected to the winding wheel 7 .

[0037] It can be seen from this embodiment that the winding motor 9 is a small brake motor, and the torque of the motor is selected to be 45N·M, which can stably pull the lamp up and into place. When working, the winding motor 9 is started, and the output shaft of the winding motor 9 passes through the first support plate 6 and is fixedly connected to the winding wheel 7, thereby controlling the rotation of the winding wheel 7 to realize the lifting and lowering of the lamp 2.

[0038] Embodiment 3:

[0039] This embodiment provides a lifting lamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0040] The self-locking mechanism includes:

[0041] A fixed frame plate 10 is fixedly mounted on the upper surface of the mounting plate 1;

[0049] It can be seen from the present embodiment that when the weight of the lamp 2 exceeds the load-bearing range or the motor fails, the lamp 2 will drive the flexible rope 3 to slide down sharply. At this time, the electric push rod 17 will quickly drive the extrusion column 16 to move toward the end of the U-shaped groove 12. The extrusion column 16 will squeeze the flexible rope 3 inward until the flexible rope 3 is tightly squeezed inside the U-shaped groove 12. At this time, the flexible rope 3 will no longer move, so that the lamp 2 will no longer fall, avoiding danger.

[0050] Embodiment 4:

[0051] This embodiment provides a lifting lamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
