Description

Technical Field

[0001] The present invention relates to the technical field of elevator shaft lighting, and in particular to a retractable protective elevator shaft lighting device. Background Art

[0002] Hoistway lighting mainly refers to the lighting system used to illuminate vertical passages in buildings (such as elevator shafts, stair shafts, etc.). Its purpose is to ensure that these relatively closed and deep spaces have enough light to meet safety and functional requirements. In the elevator shaft, the lighting system provides the necessary light for the installation, maintenance and daily operation of the elevator. When elevator installers install guide rails, cars, cables and other equipment in the shaft, sufficient lighting allows them to operate accurately and avoid installation errors or safety accidents due to insufficient light.

[0003] A Chinese invention patent with publication number CN116772169B discloses an elevator shaft lighting device, including: a lower plate, parallel to the elevator shaft wall and vertically inserted into the wire trough box; a vertical plate, vertically arranged on the side of the vertical plate away from the elevator shaft wall, and vertical plates are arranged on both sides of the wire trough box; a lamp assembly, located on the side of the wire trough box away from the elevator shaft wall, and the lamp assembly is installed on the top of the vertical plates on both sides of the wire trough box; wherein the lamp assembly includes: a lamp group heat dissipation bottom plate, arranged in parallel with the lower plate, and the two ends of the lamp group heat dissipation bottom plate are respectively fixed on the top of the vertical plates on both sides of the wire trough box; a lamp body, fixedly installed on the lamp group heat dissipation bottom plate. This application solves the technical problem in the prior art that the elevator shaft is a claustrophobic environment with poor ventilation, the heat of the lighting lamp always lingers near the lamp body, and the service life of the lighting lamp is reduced, and the lamp body is suspended on the wire trough, with a large space for heat dissipation of the lamp body.

[0004] In addition, since the elevator shaft is in a relatively narrow environment, the elevator shaft lighting device disclosed in Chinese invention patent CN116772169B cannot control the proportion of space occupied by the lighting equipment when it is installed. If the shaft space is too narrow, it will affect the range of activities of maintenance personnel during maintenance. During maintenance, personnel will also touch some surrounding debris, causing the debris to fall down. If the lighting equipment cannot effectively store the light-emitting device, the light-emitting device will be damaged. In addition, due to the large temperature difference between the inside and outside of the elevator shaft and the long-term high humidity environment, dust will adhere to the outer casing of the lighting equipment through the water mist in the air. If it is not handled for a long time, it will affect the lighting effect of the lighting equipment. Summary of the invention

[0042] The sponge block 35 can clean the dust attached to the surface of the lamp 2, thereby ensuring the lighting effect of the lamp 2.

[0043] It should be noted that the fixing rod 3 45 is internally limited in lateral movement, and when the fixing rod 3 45 rotates, it will drive the fixing rod 1 310 to rotate synchronously;

[0044] The following is the working process and principle of the above embodiment:

[0045] The initial state is as follows: the torsion spring 33 is in a twisted state, the telescopic rod 37 is in an unextended state, the spring 1 44 is in an uncontracted state, and the spring 2 415 is in an uncontracted state.

[0046] The working steps are as follows: when the personnel have finished the construction of the well, the personnel control the driving rod 314 to move on the inner wall of the storage box 1 toward the side close to the slide groove 3 46 through the external control device, so that the driving rod 314 drives the driving block 38 to move synchronously, so that the driving block 38 drives the fixing rod 1 310 to move synchronously under the interference with the slide groove 1 311, so that the fixing rod 1 310 drives the electric lamp 2 to move synchronously toward the side close to the storage box 1 through the connector 313. During the movement of the driving block 38, the driving block 38 drives the telescopic end of the telescopic rod 37 to rotate through the groove 1 39 and moves toward the inside of the storage box 1 at the same time, so that the top of the telescopic rod 37 is connected to the hinge rotatably, The block 36 drives the protective cover 34 to move, so that the protective cover 34 flips to the side close to the electric lamp 2 with the rotating rod 32 as the axis, so that the rotating rod 32 rotates inside the fixed block 31 and synchronously drives the torsion spring 33 to start rotating, so that the protective cover 34 drives the sponge block 35 to flip to the side close to the electric lamp 2 until the protective cover 34 is completely closed, and at the same time the sponge block 35 wraps the electric lamp 2. After the protective cover 34 is closed, the electric lamp 2 is stored and wrapped, which prevents people from touching the exposed electric lamp 2 when moving inside the well, prevents the installation effect of the electric lamp 2 from being reduced, and prevents falling objects inside the well from damaging the electric lamp 2, thereby improving the protective effect of the device on the electric lamp 2.

[0047] In the process of the fixed rod 1 310 moving toward the inside of the storage box 1, the fixed rod 1 310 drives the driving block 38 and the limit block 41 to move synchronously, so that the limit block 41 drives the fixed rod 2 43 to move synchronously through the fixed block 2 42, so that the fixed rod 2 43 slides inside the fixed plate 1 48 to the side away from the limit block 41 under the interference of the interference block 1 49 and the interference block 3 416, and at the same time, the interference block 1 49 contacts the slide groove 3 46 through the fixed plate 1 48, so that the slide groove 3 46 drives the fixed rod 3 45 to move toward the inside of the fixed plate 1 48 under the interference of the fixed plate 1 48. The fixing rod 1 310 moves inside, so that the fixing block 2 42 squeezes the spring 1 44 to shrink. When the elastic force of the compressed spring 1 44 is greater than the elastic force of the spring 2 415 that can shrink, the resistance block 1 49, under the elastic force of the spring 1 44, squeezes the resistance block 3 416 to move toward the inside of the limiting groove 1 414, and makes the resistance block 3 416 squeeze the spring 2 415 to shrink until the resistance block 3 416 moves to no longer conflict with the resistance block 1 49. At this time, the fixing plate 1 48 moves to the side close to the annular block 411 under the elastic action of the spring 1 44. The fixed plate 1 48 drives the rotating plate 47 to slide synchronously inside the limiting groove 2 417. At the same time, the fixed rod 3 45 begins to extend to the outside of the fixed rod 1 310, so that the fixed rod 3 45 drives the diagonal rod 410 to move inside the annular block 411, so that the diagonal rod 410 rotates twice under the resistance of the resistance block 2 412, and then the diagonal rod 410 drives the fixed rod 3 45 to rotate inside the rotating plate 47, so that the fixed rod 3 45 drives the fixed rod 1 310 to rotate synchronously, and finally the fixed rod 1 310 passes through the connector 31 3 drives the lamp 2 to rotate inside the protective cover 34, so that the sponge block 35 cleans the water mist and dust on the outer wall of the lamp 2, avoiding the problem that the dust inside the well is attached to the lamp 2 through the water mist, and can timely clean the dust attached to the outer surface of the lamp 2, thereby ensuring the lighting effect of the lamp 2 and improving the maintenance efficiency of the maintenance personnel. In addition, the protective cover 34 and the storage box 1 wrap the lamp 2, reducing the space occupied by the lamp 2 at the bottom of the well, thereby providing sufficient maintenance space for the maintenance personnel, thereby improving the utilization rate of the well space.
