Description

Technical Field

[0001] The invention relates to the technical field of lamps, and in particular to a universal structure of a liftable complete set of lamps. Background Art

[0002] Modern commercial and public buildings such as shopping malls, office buildings, and museums often use ultra-high cantilever structures in pursuit of large net space. The number of lamps installed on the top of the cantilever structure is not only large, but also often more than 6 to 10 meters above the ground. Lamps generally use grid-type fluorescent lamps, which are used frequently and have long lighting time. Modern industrial plants such as machinery manufacturing plants and subway parking garages generally have a net height of more than 10 meters. Due to the high requirements for lighting brightness, lamps generally use metal halide lamps installed on the top of the structure, and the continuous use time of the lamps is particularly long.

[0003] However, the light source and electronic ballast of the grid fluorescent lamp are consumable parts, and generally need to be repaired and replaced after one year of use. The cantilever structure of modern commercial and public buildings is too high, and there are usually escalators and equipment facilities below, which makes it impossible to use elevators to repair the lamps above, especially at escalators, where even herringbone ladders cannot be used; and ultra-high-altitude operations also increase the personal risks of maintenance personnel.

[0004] Transformers and triggers of metal halide lamps are consumable parts that need to be replaced frequently. However, due to the high net height of industrial plants and the large machinery or production lines under the lamps, it is almost impossible to use a lift to repair or replace the lamps if they break down or the light source is worn out.

[0036] The rotation drive mechanism is connected to the horizontal shaft 3 and is used to drive the horizontal shaft 3 to rotate forward and reversely, thereby driving the top cover 12 to rise and dock with the cover 11 or driving the top cover 12 to descend and separate from the cover 11.

[0037] Specifically, the rotation drive mechanism may include a worm gear 6 fixedly sleeved on the horizontal shaft 3, and a worm 7 meshing with the worm gear 6, the worm 7 is vertically arranged, and the upper end of the worm 7 is rotatably connected to the base frame 1. Specifically, the external tangent line of the worm gear 6 intersects and meshes with the thread of the vertically arranged worm 7 at 90°, forming a worm gear transmission structure. The rotation drive mechanism also includes a switching part for driving the worm 7 to rotate.

[0038] Among them, the lower end of the worm 7 is set as a coupling rod 9, and the adapter includes a standard rod body 22. The upper end of the standard rod body 22 is connected to a coupling head 21, and the coupling head 21 is a steel sleeve type. The coupling head 21 is used to cooperate with the coupling rod 9.

The two ends of each section of the standard rod body 22 are internal and external thread interfaces respectively, and an anti-drop fastener is provided at one end of the interface. When in use, it can be assembled by itself according to the height of the lamp.

[0039] Among them, the two ends of the horizontal shaft rod 3 are installed on the base frame 1 through the first rotating bearing 5; the two ends of the worm 7 are installed on the base frame 1 through the second rotating bearing 14; the part of the lower end of the worm 7 extending out of the second rotating bearing 14 is the coupling rod 9.

[0040] The base frame 1 is provided with a steel sleeve 8 covering the coupling rod 9 at the coupling rod 9, and the inner diameter of the steel sleeve 8 is larger than the outer diameter of the coupling head 21 and the coupling rod 9. The portion of the lower end of the worm 7 inserted into the steel sleeve 8 is the coupling rod 9, the length of the coupling rod 9 is less than or equal to the length of the steel sleeve 8, and its shape is set to a "triangular prism" structure; the steel sleeve 8 is fixed on the base frame 1, and a circular hole is provided on the top surface of the steel sleeve 8, and the diameter of the circular hole is the same as the inner diameter of the second rotating bearing 14 and the outer diameter of the worm 7.

[0041] Among them, each of the four sides of the cover 11 and the inner side of the vertical surface of the base frame 1 is provided with a slot 19, and the corresponding side of the top cover 12 is provided with a snap spring 17 corresponding to the slot 19. The snap spring 17 is preferably in a bead shape, and the slot 19 and the snap spring 17 are matched with each other, so that when the top cover 12 is in place, it can bear its own weight and prevent it from falling.

[0042] The bottom surface of the top cover 12 is provided with at least one hook ear 18, preferably two hook ears 18 are symmetrically provided on the center lines of the opposite sides of the bottom surface of the top cover 12; the lower end of the standard rod body 22 is connected with a hook head 23. The hook ear 18 is arranged in the same direction as the locking wire ring 20. When the top cover 12 is in place in the base body, the hook ear 18 can be pulled downward to separate the two. The horizontal position of the top cover 12 can also be adjusted by the hook ear 18 during the rising process of the top cover 12.

[0043] Among them, there are three static contacts 13, which are L, N, and PE phases respectively, and the length of the PE phase static contact 13 is longer than that of the L and N phase static contact 13.

[0044] The working principle of the present invention is: the coupling rod 9 is rotated by the standard rod body 22, that is, the worm 7 is rotated to drive the worm gear 6, the horizontal shaft rod 3, and the steel strand reel 4 to rotate. Through this process, the flexible steel strand 10 tightly wound on the steel strand reel 4 is continuously released downward, and the top cover 12 is lowered and finally reaches a height that is convenient for operation and maintenance. The coupling rod 9 is rotated in the reverse direction to continuously lift the top cover 12 into the base body, so that the complete set of lamps can reach the use condition.

[0045] Example 1

[0046] like Figure 3 As shown, due to the high cantilever structure height of modern commercial and public buildings, there are usually escalators and equipment facilities below, which makes it impossible to use elevators to repair the lamps above, especially at escalators, even ladders cannot be used, and ultra-high altitude operations also increase the personal safety risks of maintenance personnel. This embodiment installs a liftable complete set of grid fluorescent lamps 24 in the above-mentioned universal structure of liftable complete sets of lamps, which effectively solves the technical problem of being unable to repair and replace light sources, and also solves the problem of high safety risks of ultra-high altitude operations.

[0047] In practice, since the top cover 12 of the liftable body 2 does not serve as a reflector for the light source, the cover 11 of the base body and the top cover 12 can be made of PC polycarbonate material to reduce the weight of the lamp, and the grid fluorescent lamp 24 is integrally embedded and fixed in the top cover 12 .

[0048] When the complete set of lamps fails or the light source is worn out and needs to be repaired and replaced, first connect the coupling head 21, hook head 23, and standard rod body 22 according to the height of the lamp, insert the coupling head 21 into the steel sleeve 8, make the coupling head 21 and the coupling rod 9 socketed in place, rotate the coupling rod 9 about one circle, then the worm 7 rotates to drive the worm gear 6, the horizontal shaft 3, and the steel strand reel 4 to rotate, so that the end of the flexible steel strand 10 tightly wound on the steel strand reel 4 is loosened and slightly released by a certain length. Then use the hook head 23 to pull the hook ear 18 downward in turn to pull the retaining spring 17 out of the card slot 19, which is reflected in the top cover 12 of the liftable body 2 being separated from the base body. Next, use the coupling head 21 to continue to rotate the coupling rod 9, and as the flexible steel strand 10 is released, the moving contact 15 is separated from the static contact 13, and then the lift body descends to a height that is convenient for operation. After the inspection and replacement is completed, the coupling rod 9 is rotated in the opposite direction using the standard rod body 22. As the flexible steel strand 10 is wound around the steel strand reel 4 one circle at a time, the top cover 12 of the liftable body 2 continues to rise. Next, the moving contact 15 is inserted into the static contact 13, the power is turned on, and finally the retaining spring 17 is inserted into the retaining groove 19, and the entire implementation process is completed.

[0049] Example 2

[0050] like Figure 4 As shown, the net height of industrial plants is generally more than 10 meters. In addition, large machinery or production lines are arranged below the lamps. Once the lamps above fail or the light source is worn out, it is almost impossible to use a lift to repair or replace them. This embodiment installs the above-mentioned universal structure of liftable complete sets of lamps on the roof of the industrial plant, and installs liftable complete sets of metal halide floodlights in the structure, which effectively solves the technical problem of being unable to repair and replace the light source, and also solves the problem of high safety risks in ultra-high altitude operations.

[0051] The shape and position relationship of the parts in each component of this embodiment are exactly the same as those described above; in practice, since the top cover 12 of the liftable body 2 can also serve as a reflector for the light source, stamped aluminum can be used; the transformer of the metal halide lamp is heavier, so a reinforcing strip 25 is added between the two locking wire rings 20 of the liftable body 2, the transformer and the trigger are installed above the center of the reinforcing strip 25, and the metal halide light source is installed below the center; when the top surface of the transformer is higher than the line between the two locking wire rings 20, in order to stabilize the center of gravity of the lamp, the top cover 12 is passed through above the top surface of the transformer, and the insulating rope 26 is fixedly connected between the flexible steel strands 10, and the various components of the metal halide floodlight are separately installed in the liftable body 2.

[0052] When the complete set of lamps fails or the light source is worn out and needs to be repaired and the light source replaced, the implementation method and steps are the same as those in Example 1.

[0053] It can be seen from the above embodiments that 1. the liftable complete lamp of the present invention not only changes the structural composition of the ordinary lamp, but also the liftable body 2 is embedded in the base body during the use of the lamp, and the appearance is beautiful and simple;

[0054] 2. The driving transmission mechanism of the lamp adopts a 90° worm gear structure. The unidirectional force transmission characteristics and self-locking property of the worm gear structure not only save the backstop device and reduce the manufacturing cost, but also simplify the internal mechanical structure of the complete set of lamps, greatly reducing its own failure rate;

[0055] 3. The liftable body 2 can be used to embed a complete set of lamps or to install various parts of the lamps, and the top cover 12 of the liftable body 2 can also serve as a light source reflector, thereby improving universal applicability;

[0056] 4. The adapter uses a standard length rod, which can be assembled on site into the required length according to the actual elevation. It is not only easy to operate but also easy to store;

[0057] 5. The liftable complete set of lamps overcomes the technical defect that the lamps cannot be repaired by using lifting equipment (or ladders) due to the high cantilever height of the building or obstacles of ground equipment and facilities. The process of repairing lamps at high altitude is converted into ground operation. On the one hand, it solves the problem of high safety risks of ultra-high altitude operations, and on the other hand, it reduces maintenance costs and saves a lot of manpower investment.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
