[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the inherent problems of headlamps, such as shadows, narrow field of vision, and obstruction of observation for other workers, this invention provides a shaft lighting device. This device, through prefabricated installation of a first and second lighting platform on the elevator car roof, can create a three-dimensional lighting space with the adjustment of a telescopic frame. The multi-point coordinated illumination of the first and second light sources ensures adequate lighting around the perimeter and on the roof operating area. Furthermore, multi-point lighting reduces the shadows cast by workers blocking a single light source, and the evenly distributed light sources minimize glare, making it more suitable for multi-person collaborative construction or maintenance.

[0020] It should be noted that the shaft lighting device described in this utility model is used in, but not limited to, elevator shafts. For ease of explanation, this utility model only uses the application of the shaft lighting device in elevator shafts as an example. The principle of the shaft lighting device applied to other types of equipment is essentially the same as that applied to elevator shafts, and will not be described in detail here.

[0021] Please see Figure 1-4This utility model provides a shaft lighting device for installation on the top of an elevator car 6. The device includes a first lighting platform 1, a second lighting platform 2, and a telescopic frame 3. The first lighting platform 1 has several first light sources 11 for upward illumination; the second lighting platform 2 has several second light sources 201 for downward illumination, forming a combined lighting system with the first light sources 11 to effectively illuminate the space between the first lighting platform 1 and the second lighting platform 2, as well as the surrounding shaft walls. The telescopic frame 3 is positioned between the first lighting platform 1 and the second lighting platform 2, with one end for installation on the top of the elevator car 6 and the other end being a movable end that drives the second lighting platform 2 to rise and fall. This allows it to have a usage position opposite to the first lighting platform 1, forming a three-dimensional lighting space, and a storage position where it descends and stacks on top of the first lighting platform 1. When maintenance is required, the second lighting platform 2 is raised to provide sufficient lighting coverage and operating space; when in the storage position, it is retracted without excessively occupying the top space of the elevator car 6.

[0022] In this embodiment, please refer to Figure 1 In order to provide illumination for the upper well wall so that maintenance personnel can easily observe the condition of the upper well wall, the second lighting platform 2 is also equipped with several third light sources 202 for upward illumination; the first light source 11, the second light source 201 and the third light source 202 are all lighting fixtures.

[0023] The first lighting platform 1 and the second lighting platform 2 are both square frames that match the size of the elevator car 6, which can pass over the elevator hoisting cables to avoid interference and provide a mounting frame for the light source.

[0024] Understandably, when it is necessary to inspect the well wall, only the third light source 202 can be turned on. At this time, the third light source 202 will illuminate the upper well wall, which will facilitate the inspection of the well wall. It passes over the head of the staff, avoiding the staff's body from blocking the light source. Its lighting effect is more suitable for well wall lighting and inspection.

[0025] In one embodiment, please refer to Figure 1-6To facilitate the lifting and lowering operation of the second lighting platform 2, the telescopic frame 3 includes sleeves 31, telescopic rods 32, and locking members 33. Several sleeves 31 are fixedly connected to the first lighting platform 1. When installed on the elevator car 6, they can extend into the elevator car 6 and be fixed to the wall of the elevator car 6. There are four sleeves 31 and four telescopic rods 32. The telescopic rods 32 are slidably connected to the inner side of the sleeves 31 in a one-to-one correspondence. The locking members 33 are installed on the first lighting platform 1 in a one-to-one correspondence with the telescopic rods 32. The telescopic rods 32 have at least two limiting holes 321 in the vertical direction that correspond to the locking members 33, so that the locking members 33 can be inserted into the limiting holes 321 in the use position and the storage position for locking and limiting. In use, the operator can unlock the locking piece 33, pull out the first lighting platform 1 directly, and under the sliding guide of the telescopic rod 32, it can be raised to a position higher than the head. Then, the locking piece 33 can be locked in place of the telescopic rod 32.

[0026] Specifically, the locking component 33 includes a support frame 331 and a locking bolt 332. The support frame 331 is fixedly connected to the first lighting platform 1 and has a threaded hole 333. The locking bolt 332 is threaded into the threaded hole 333. One end of the locking bolt 332 away from the support frame 331 is inserted into the corresponding limiting hole 321. By rotating and adjusting the locking bolt 332, the insertion and withdrawal actions are formed. When the locking bolt 332 is inserted into the limiting hole 321, it is locked. When the locking bolt 332 is disengaged from the limiting hole 321, it is unlocked.

[0027] Furthermore, to provide a limit for the pull-out, the bottom of the telescopic rod 32 is provided with a limit block 301, and the inner side of the sleeve 31 is provided with a baffle 302. When the telescopic rod 32 is pulled out and the limit block 301 abuts against the bottom of the baffle 302, the bottom limit hole 321 aligns with the threaded hole 333, reaching the use position; when the first lighting platform 1 is pushed down and abuts against the top of the support frame 331, the upper limit hole 321 aligns with the threaded hole 333, reaching the storage position.

[0028] In one embodiment, please refer to Figure 5 and Figure 6In order to provide the first light source 11 with the function of illuminating the elevator car in addition to maintenance lighting, the first light source 11 includes a flip base 111, a flip assembly 112, and a lamp 113. The flip base 111 is rotatably connected to the first lighting platform 1, and the lamp 113 is mounted on the flip base 111. The movable end of the flip assembly 112 is connected to the flip base 111, driving the flip base 111 to flip so that the lamp 113 faces upward or downward. This way, it can provide lighting in the elevator car when no maintenance is being performed, and when maintenance lighting is required, it flips upward to illuminate the elevator shaft, and vice versa.

[0029] Understandably, the top of the elevator car has a through hole that connects to the light fixture 113, allowing the light source to penetrate into the elevator car.

[0030] Furthermore, to enable seamless flipping during the pull-out action, the flipping assembly 112 includes a rack 112a and a gear 112b. The gear 112b is coaxially connected to the rotation axis of the flipping seat 111. The rack 112a is installed at the tail end of the telescopic rod 32 and meshes with the gear 112b during the pull-out process. The one-way stroke of the rack 112a drives the flipping seat 111 to flip 180°. That is, during the pull-out action, when the telescopic rod 32 moves upward to the point where the rack 112a meshes with the gear 112b, it can drive the flipping seat 111 to rotate. When the telescopic rod 32 moves to the limit position of the baffle 302 on the limit block 301, the flipping seat 111 rotates 180° to the upward lighting position. Conversely, when the telescopic rod 32 moves downward and disengages from the gear 112b, the flipping seat 111 rotates 180°, turning the lighting fixture 113 downward.

[0031] Understandably, the flipping assembly 112 can also use a rotation drive mechanism with a drive motor or a hydraulic push rod, both of which are existing mature equipment and are not limited to here.

[0032] Furthermore, in order to stabilize the lamp 113 in the upward or downward lighting position, an annular cover 4 is also included, which is connected to the first lighting platform 1 and is fitted onto the outer side of the flip seat 111 in a corresponding manner. The inner side of the annular cover 4 is provided with an elastic limiting ring 401, and the outer side of the flip seat 111 is provided with a limiting groove 114 corresponding to the position of the elastic limiting ring 401. This forms an elastic snap-fit ​​positioning of the flip seat 111 in the horizontal position, without affecting the rotation adjustment of the flip seat 111 during the pull-out action.

[0033] In one embodiment, please refer to Figure 7To provide emergency lighting during power outages, a power supply control system 5 is also included. The power supply control system 5 includes a main power module 51, an emergency power module 52, and an automatic power switching module 53. The main power module 51 is connected to mains power and electrically connected to the first light source 11, the second light source 201, and the third light source 202. The power supply control system 5 also includes a manual switch 54, which is connected in series in the power supply circuit between the main power module 51 and the first light source 11, the second light source 201, and the third light source 202. Each light source is equipped with a separate manual switch 54, allowing individual control of the on / off state of each light source. The emergency power module 52 includes a battery, which is connected to the first light source 11 and the second light source 201 via the power supply circuit. The system is electrically connected to the third light source 202, and the battery is connected to AC power for charging until it is fully charged. The automatic power switching module 53 includes a relay, the coil of which is connected in the circuit of the main power module 51. The normally closed contact of the relay is connected in series in the power supply circuit of the emergency power module 52 to the first light source 11, the second light source 201, and the third light source 202. When the main power module 51 is supplying power normally, the relay coil is energized, its normally closed contact is open, and the emergency power module 52 does not supply power to the lighting platform. When the main power module 51 is de-energized, the relay coil is de-energized, its normally closed contact is closed, and the emergency power module 52 supplies power to the first light source 11, the second light source 201, and the third light source 202. Furthermore, a manual switch can be individually installed on the emergency power supply line of each relay for controlling its on / off state.

[0034] Understandably, in the event of a power outage, the first light source 11 can illuminate the elevator car, while the third light source 202 illuminates the elevator shaft, making it easier for maintenance personnel to locate the elevator from top to bottom; in emergency situations, the second light source 201 can be turned on manually without direct power supply.

[0035] It should be noted that the charging and power-off of the battery can be handled by installing a corresponding charging unit, which automatically cuts off the power after the battery is fully charged. Existing mature power control components can be used, so we will not go into details here. The coil and normally closed contacts of the relay are composed of conventional relay structures, so we will not go into details here either.

[0036] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
