Description

Technical Field

[0001] The utility model discloses a device for removing embedded lamps for navigation lights, belonging to the technical field of embedded lamps for waterways. Background Art

[0002] The embedded lamps in the airport pavement lighting system mainly include runway centerline lights, touchdown zone lights and taxiway centerline lights, and the runway centerline lights and touchdown zone lights are set according to the precision level of the approach lighting system. The centerline lights are set along the centerline of the road and embedded to a certain depth on the pavement surface to provide visual guidance for aircraft taxiing, taking off and landing at night or in low visibility conditions. They are the most installed navigation lights at civil airports. Due to the frequent takeoffs and landings of aircraft, embedded lamps will have many problems such as lamp body damage, lighting system damage, and tire colloid adhesion. If damaged or failed lamps are not replaced in time, it will not only affect the pilot's pavement vision and judgment of the landing point, but in severe cases it will also cause damage to the tires, especially in rainy and snowy weather with complex climates, which poses a great safety hazard.

[0003] At present, the replacement of embedded lamps on airport runways is done manually, using a combination of various manual tools and the principle of levers. Two people are required to use foot pedals to remove the lamps at the same time. Because embedded lamps on airport runways have a certain degree of sealing, when the above operation mode is adopted, the force will be uneven, which will cause mechanical wear to the sealing ring. In severe cases, the sealing ring needs to be replaced, resulting in excessive consumption of resources and affecting the operation effect. In addition, the disassembly efficiency is low, the speed is slow, and it is dangerous to a certain extent. It is easy to cause mechanical damage and the appearance of airport FOD foreign objects, posing a safety hazard to operational safety and flight safety. Based on the above difficulties and pain points, a device for removing embedded lamps for navigation lights is proposed. Utility Model Content

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figure 1As shown, the first embodiment of the utility model provides a navigation light embedded lamp removal device based on the prior art, including a support frame 1, an L-shaped grab rod 2, a pull rod 3, a positioning frame 4, a drive motor 5, a driving gear 6, a driven gear 7, and a lead screw 9. The specific connection relationship of the above components will be described in detail below.

[0026] like Figure 2-4 As shown, the positioning frame 4 is fixed to the outer top of the supporting frame 1 by bolts, the driving motor 5 is installed on the positioning frame 4 by bolts, the main shaft of the driving motor 5 is sleeved with a driving gear 6, a through hole is provided at the central axis of the supporting frame 1, a positioning seat 8 with a through hole in the middle is fixed to the outer top of the through hole of the supporting frame 1, and the driven gear 7 is rotatably installed on the positioning seat 8 through a tapered roller bearing. The driven gear 7 cooperates with the driving gear 6, and the driven gear 7 is threadedly matched with the lead screw 9 through a threaded hole provided in the middle. The lead screw 9 passes through the driven gear 7, the positioning seat 8 and the supporting frame 1 in sequence, and the end of the lead screw 9 in the supporting frame 1 is rotatably connected with a grabbing mechanism.

[0027] The grabbing mechanism comprises a pull rod 3 rotatably connected to one end of the lead screw 9 in the middle, and an L-shaped grabbing rod 2 is symmetrically hinged on one side of the pull rod 3 away from the motor, and the short sides of the two L-shaped grabbing rods 2 are arranged opposite to each other.

[0028] The supporting frame 1 may be cylindrical, conical, polygonal or polygonal. The embodiment in the attached drawings is cylindrical. The specific connection mode of the pull rod 3 and the lead screw 9 for rotation connection is preferably but not limited to the following embodiments:

[0029] One implementation method: Figure 5 As shown, a threaded blind hole is provided at the bottom end of the screw 9, and a stepped through hole is provided in the middle of the pull rod 3. After the bottom end of the screw 9 passes through the stepped through hole, 1-2 bearings 11 are respectively sleeved thereon, and then the bearings 11 are fixed in the stepped through hole through the thrust ring 10 and the threaded blind hole, thereby achieving the effect of rotational connection between the pull rod 3 and the screw 9.

[0030] Another implementation method: Figure 6 As shown, a large ring stage is fixed to the bottom end of the lead screw 9, and a stepped through hole is provided in the middle of the pull rod 3. After the lead screw 9 passes through the stepped through hole from the top, the large ring stage and the large diameter hole of the stepped through hole are used to limit the position, thereby achieving the effect of rotational connection between the pull rod 3 and the lead screw 9.

[0031] How it works:

[0032] like Figure 7-9As shown, the current airport runway embedded lamps mainly involve runway centerline lights, touchdown zone lights and taxiway centerline lights, etc. The centerline lights are arranged along the center line of the road and embedded in the pavement surface to a certain depth. Therefore, when disassembling, the cylindrical support frame 1 is first placed directly above the lamp, that is, above the lamp buckled on the ground, so that the upper surface of the lamp is in the support frame 1. There are two symmetrically arranged lamp extraction holes on the side of the airport runway embedded lamp. Therefore, the short sides of the two L-shaped grab bars 2 are placed in the lamp extraction holes. The driving motor 5 is powered by an external power supply or municipal power supply to rotate the main shaft, and the driving gear 6 is driven to rotate with the driven gear 7. Since the driven gear 7 is provided with a threaded hole in the middle and is threaded with the lead screw 9, the lead screw 9 moves upward to perform a pulling operation, and the airport runway embedded lamp is rotated and pulled out from the installation hole embedded in the pavement surface to a certain depth, which solves the problem that the existing airport runway embedded lamps are manually removed and replaced with low efficiency and certain dangers, thereby improving the working efficiency, saving working time, and reducing the labor intensity.

[0033] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described here.
