Description

Technical Field

[0001] The invention relates to the technical field of airport navigation aid maintenance, and in particular to an airport ground lamp disassembly and assembly auxiliary device. Background Art

[0002] In the airport navigation lighting system, embedded navigation lights are widely used in key areas such as the boundaries, center lines, and touchdown zones of runways and taxiways. At present, the lamp body of the embedded navigation light is usually composed of an upper cover and an inner cover, which encapsulates the lighting components and circuit system inside and is installed and fixed by a lamp holder pre-buried in the ground lamp pit. During maintenance, the lamp body and the lamp holder must be separated first, and then the circuits in the lamp body or the lamp holder must be further repaired or maintained. In order to meet the requirements of compressive strength, waterproofness, and dustproofness, a multiple sealing structure is adopted between the lamp body and the lamp holder. Due to long-term exposure to the outdoor environment, the sealing ring is easy to harden and adhere, resulting in a very tight and firm combination of the lamp body and the lamp holder. At present, special handles or screwdrivers and other tools are usually used in conjunction with tool holes to pry the upper cover to separate the lamp body from the lamp holder, which is time-consuming, labor-intensive, and inefficient. At the same time, since manual operation is difficult to ensure the synchronous and balanced force on both sides, it is easy to cause local deformation of the upper cover, affecting the sealing performance and optical path collimation, and reducing the working performance of the lamp. In addition, when repairing the dismantled lamp body, it is usually necessary to adjust the position and direction of the lamp body. Currently, there is no special support tool suitable for fixing the lamp body, which makes the operation inconvenient, further reducing the maintenance efficiency of the embedded navigation lights.

[0003] In response to the above problems, there are some improvement schemes in the prior art. For example, the patent with publication number CN212578510U provides an embedded navigation light picking and placing tool, which includes a lifting mechanism and a hook assembly. The hook assembly corresponds to the tool hole of the lamp holder, and the lifting mechanism provides power to remove the lamp body from the lamp holder, thereby saving manpower operation. However, this technical solution still has certain limitations: first, when in use, the relative position and direction of the picking and placing tool and the lamp body need to be accurately adjusted to ensure that the hook assembly and the tool hole are matched, and the operation process is quite cumbersome; secondly, the picking and placing tool has a single function and cannot provide stable support for the maintenance operation of the lamp body. There is still a lot of room for improvement in practical functions. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides an airport ground lamp disassembly and assembly auxiliary device, which can automatically drive the lamp body to separate from the lamp holder, reduce manual labor intensity, improve efficiency, and avoid deformation of the upper cover of the lamp cover due to uneven force; this auxiliary device can provide stable support for the lamp body and can flexibly adjust the direction of the lamp body, bringing convenience to maintenance and inspection operations.

When the clamping mechanism moves upward with the traction belt, it can pass through the middle of the two sets of vacuum suction cups.

[0010] In a preferred embodiment, a controller is installed in the rotating body, and the controller can adjust the working state of the motor device. The operating button of the controller is installed on the outer end surface of a rotating shaft.

[0011] In a preferred embodiment, a pair of guide rollers are installed on the lower side of the rotating body, and the free end of the traction belt passes through between the two guide rollers and extends downward.

[0012] In a preferred embodiment, the adsorption assembly includes a placement seat, the placement seat is fixed to the lower side of the rotating body, and the vacuum suction cup is located below the placement seat and is fixedly connected to the placement seat via a column.

[0013] In a preferred embodiment, the upper ends of all vacuum suction cups in the adsorption assembly are connected to the atmosphere through an air intake pipeline, and a stop valve is provided on the air intake pipeline.

[0014] In a preferred embodiment, the adsorption assembly includes a limit switch.

[0015] In a preferred embodiment, the clamping mechanism comprises a connecting seat, which is fixedly connected to the lower end of the traction belt; two parallel rods extending obliquely downward are hinged on each side of the connecting seat, and the lower ends of the two parallel rods are hinged to one of the clamping arms; the connecting seat and the two parallel rods on the corresponding side and the clamping arm form a parallel four-bar linkage mechanism, and two latches are fixed on the opposite side walls of the two clamping arms; an elastic member is installed in the clamping mechanism; Furthermore, in the clamping mechanism, a protrusion is reserved on each of the two symmetrical parallel rods located on both sides of the connecting seat, and the protrusion is located inside the connecting seat.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1 As shown, the lamp body of the existing embedded navigation light is usually composed of an upper cover 2 and an inner cover 1. The lamp body encapsulates the lighting components and the circuit system, and is installed and fixed by a lamp holder 4 pre-buried in the lamp pit; tool holes 3 are opened on the opposite sides of the upper cover 2. The upper cover 2 is pried with a tool such as a screwdriver in conjunction with the tool holes 3 to separate the lamp body from the lamp holder 4, so as to inspect and maintain the circuits inside the lamp body or the lamp holder 4.

[0038] See also Figure 1-Figure 7 As shown, the present invention discloses an auxiliary device for disassembling and assembling airport ground lighting, which is composed of a support frame, a rotating body 9, a traction mechanism, an adsorption component, a clamping mechanism and a locking mechanism; The support frame is used to provide support for the rotating body 9. When the auxiliary device is working, the support frame is placed on the ground and does not block the space above the embedded navigation light. Two shaft seats 11 are fixed on the upper end of the support frame. The two ends of the rotating body 9 are provided with horizontally extending rotating shafts 12, and the two rotating shafts 12 are respectively rotatably connected to the two shaft seats 11 at the upper end of the support frame, so that the rotating body 9 can rotate; when the auxiliary device is working, the rotating body 9 is supported by the support frame and is located directly above the embedded navigation light; The traction mechanism includes a motor device 24, a pulley 22 and a traction belt 23. The motor device 24 is fixed in the rotating body 9. The pulley 22 is rotatably connected to the wheel seat 21 inside the rotating body 9. The motor device 24 is in transmission connection with the pulley 22. The traction belt 23 is in the shape of a flat belt, one end of which is wound around the pulley 22, and the other end is a free end and extends downward out of the rotating body 9. When the motor device 24 drives the pulley 22 to rotate, the traction belt 23 located outside the rotating body 9 can move up and down. The adsorption assembly includes two groups of vacuum suction cups 6, which are respectively located on both sides of the traction belt 23 in the thickness direction and are symmetrically distributed. Each group of vacuum suction cups 6 includes one or more vacuum suction cups 6, and the adsorption end of the vacuum suction cup 6 faces downward. The clamping mechanism is connected to the lower end of the traction belt 23. The lower end of the clamping mechanism is provided with two clamping arms 8 with adjustable spacing. The two clamping arms 8 are provided with latches 7 for matching with the two tool holes 3 of the upper cover 2 on opposite sides. The two latches 7 are spaced apart along the width direction of the traction belt 23. When the traction belt 23 drives the clamping mechanism to move upward, the clamping mechanism can pass through the middle of the two groups of vacuum suction cups 6. The locking mechanism is installed between the rotating body 9 and the support frame, and is used to lock the rotating body 9 and the support frame. In the locked state, the rotating body 9 cannot rotate; in the specific implementation process, the locking mechanism can be a locking bolt 13, and can also be implemented based on the matching structure of the ball head plunger and the positioning hole.

[0039] See also Figure 1 , Figure 6 As shown, when the lamp body and the lamp holder 4 are separated, the auxiliary device is moved to the ground where the embedded navigation light to be disassembled is installed, and the position of the support frame is adjusted so that the rotating body 9 is located above the upper cover 2; the traction belt 23 is unwound to a sufficient length, the upper cover 2 is clamped by the hand-held clamping mechanism, and the two pins 7 are inserted into the corresponding tool holes 3; the motor device 24 is used to drive the pulley 22 to rotate, and the traction belt 23 is reeled in, and the traction belt 23 drives the upper cover 2 to move upward through the clamping mechanism, so that the lamp body and the lamp holder 4 are separated; compared with manual operation, it is more labor-saving and efficient, and the forces on the opposite sides of the upper cover 2 during the traction process tend to be balanced, which can effectively avoid deformation.

[0040] See also Figure 5-Figure 10As shown, if further operation is required on the separated lamp body, the motor device 24 continues to run, driving the lamp body to continue to move upward until the top of the upper cover 2 contacts the vacuum suction cup 6 and presses out the air in the vacuum suction cup 6. At this time, the upper cover 2 establishes a multi-directional connection with the clamping mechanism and the adsorption component. Specifically, the clamping mechanism clamps and fixes the upper cover 2 in the width direction of the traction belt 23, and the two groups of vacuum suction cups 6 respectively adsorb and fix the top of the upper cover 2 on both sides of the thickness direction of the traction belt 23, thereby firmly connecting the adsorption component, the clamping mechanism and the lamp body. The rotating body 9 can provide stable and reliable support for the lamp body. Thereafter, the direction of the lamp body can be flexibly adjusted by rotating the rotating body 9. After the direction of the lamp body is locked by the locking mechanism, the sealing ring can be replaced quickly and easily, the lamp body can be disassembled, and the internal components of the lamp body can be inspected or replaced.

[0041] The core advantage of the auxiliary device is that the flat belt-shaped traction belt 23 is used as the main transmission component. Based on the flexibility of the traction belt 23, the position of the clamping mechanism has a large degree of freedom, and can be quickly combined and connected with the upper cover 2 of the embedded navigation light. There are no longer strict precision requirements on the relative position and direction of the auxiliary device and the embedded navigation light, making the auxiliary device more convenient and efficient to use and easy to operate.

[0042] At the same time, the traction belt 23 is in the shape of a flat belt and has a good directional function, that is, the width of the traction belt 23 is constant in the process of moving up and down. After the lamp body is separated from the lamp holder 4, the clamping mechanism and the lamp body can automatically adjust to a specific position and direction based on gravity and the directional characteristics of the traction belt 23 during the upward movement of the traction belt 23. There is no need to install an additional complex guiding mechanism, and the space avoidance between the adsorption component and the clamping mechanism, as well as the stable cooperation between the adsorption component, the clamping mechanism and the lamp body can be achieved at a low cost, making the implementation cost of the auxiliary device low and the overall structure simple and compact.

[0043] In the design of the existing embedded navigation lights, although the models and sizes are quite different, the top of the upper cover 2 has a planar portion, and tool holes 3 are reserved on both sides of the upper cover 2. These are inherent structural features of the embedded navigation lights. When the auxiliary device is in use, the adsorption component cooperates with the planar portion, and the clamping mechanism cooperates with the tool hole 3. Based on the inherent characteristics of the embedded navigation lights, the auxiliary device can be applied to embedded navigation lights of different specifications, reflecting extremely high applicability.

[0044] In a specific implementation process, the vacuum suction cup 6 is a vacuum adsorption type silicone disc, the edge of which is provided with an annular sealing flange, and the traction belt 23 is a polyester fiber woven belt.

[0045] Preferably, Figure 2 , Fig.11As shown, the support frame is composed of a base 17 and a door frame 14, and the rotating body 9 is supported by the door frame 14. The base 17 and the door frame 14 adopt a folding structure or a combined structure, so that the auxiliary device is easy to store and carry; for example, the base 17 and the door frame 14 are connected by rotation so that they can be folded and unfolded, and locking components such as locking pins are provided between the base 17 and the door frame 14 to ensure that the base 17 and the door frame 14 can stably maintain the folded and unfolded state; Furthermore, a diagonal brace 16 is provided between the base 17 and the gantry 14, and the diagonal brace 16 can be a movable connecting rod or a pneumatic telescopic rod, thereby ensuring that the base 17 and the gantry 14 have good structural stability in the unfolded state, so as to provide stable support for the rotating body 9; Furthermore, the base 17 is equipped with a maintenance tool assembly 5, which can be electronic instruments such as electrical testing and optical testing, maintenance and care tools, and other common items for airport lighting maintenance; the base 17 is provided with a handle 15; Based on the above improved design, the convenience and portability of the auxiliary device during the airport ground lighting maintenance operation can be significantly improved.

[0046] Preferably, Figure 3 , Figure 4 As shown, the rotating body 9 is a hollow cylindrical structure, and a detachable arc plate 10 is provided on the side of the rotating body 9. The motor device 24 and the pulley 22 are installed in the inner cavity of the rotating body 9; thereby, the structure and appearance of the rotating body 9 are relatively simple, and good protection can be provided for the motor device 24 and the pulley 22, so as to improve the working stability and avoid injuries to personnel during the operation of mechanical parts.

[0047] Preferably, Figure 4 As shown, a battery 20 for providing electric energy to the motor device 24 is fixed inside the rotating body 9, thereby enabling the auxiliary device to work independently without the aid of an external power source, thereby improving the flexibility of use.

[0048] Preferably, Figure 4As shown, a controller 19 is installed in the rotating body 9, and the controller 19 can adjust the working state of the motor device 24, such as starting, stopping, speed and steering. The operation button 18 of the controller 19 is installed on the outer end surface of a rotating shaft 12; therefore, the operation button 18 will not change position with the rotation of the rotating body 9, so as to facilitate the operation of maintenance personnel; at the same time, the controller 19 can monitor the traction force of the traction belt 23 and preset the traction force threshold. When the traction belt 23 pulls the lamp body up to the point where the lamp body and the adsorption component are against each other, the lamp body cannot continue to move up, and the traction force of the traction mechanism will increase. After the controller 19 detects that the traction force reaches the threshold, it automatically stops the motor device 24 from running, thereby automatically adjusting the lamp body to the expected position, reducing the difficulty of operation, and helping to ensure the working stability of the traction mechanism.

[0049] Preferably, Figure 8 As shown, a pair of guide rollers 28 are installed on the lower side of the rotating body 9, and the free end of the traction belt 23 passes through the two guide rollers 28 and extends downward; based on the setting of the guide rollers 28, on the one hand, the stability of the moving path of the traction belt 23 can be ensured, and on the other hand, it is helpful to reduce the resistance of the traction belt 23 during the up and down movement, making its winding and unwinding smoother.

[0050] Preferably, Figure 4 As shown, the adsorption assembly includes a mounting seat 25, and the mounting seat 25 is fixed to the lower side of the rotating body 9. The vacuum suction cup 6 is located below the mounting seat 25 and is fixedly connected to the mounting seat 25 via a column 26; thereby, the adsorption assembly constitutes a relatively independent module, which is fixedly connected to the rotating body 9 by assembly, thereby improving the ease of implementation of the auxiliary device; in addition, the column 26 can be connected to the mounting seat 25 in a position-adjustable manner, thereby making the position of the vacuum suction cup 6 in the adsorption assembly adjustable according to the specifications of the embedded navigation light, so as to improve the applicability of the auxiliary device.

[0051] Preferably, Figure 4 , Fig.12 As shown, the upper ends of all the vacuum suction cups 6 in the adsorption assembly are connected to the atmosphere through an air inlet pipe 29, and a stop valve 27 is provided on the air inlet pipe 29; therefore, when the stop valve 27 is in the cut-off state, the upper end of the vacuum suction cup 6 is not connected to the outside world, and the upper cover can be adsorbed normally; when the stop valve 27 is adjusted to the open state, air enters the vacuum suction cup 6 through the air inlet pipe 29, the negative pressure environment inside the vacuum suction cup 6 is destroyed and the adsorption effect is lost, so the upper cover can be separated from the vacuum suction cup 6 conveniently and labor-savingly.

[0052] Preferably, Fig.13As shown, the adsorption assembly includes a limit switch 30. When the top of the upper cover 2 of the lamp body hits the limit switch 30, the limit switch 30 stops the motor device from running. At this time, the top of the upper cover 2 hits the vacuum suction cup 6 and presses out the air in the vacuum suction cup 6. Therefore, when the lamp body is driven upward by the traction belt, the motor device will automatically stop running after the lamp body reaches the expected position. The working method is more automatic, reducing the difficulty of operation.

[0053] Preferably, Fig.14 As shown, the clamping mechanism includes a connecting seat 31, and the connecting seat 31 is fixedly connected to the lower end of the traction belt 23; on the two opposite sides of the connecting seat 31, each side is hinged with two parallel rods 34 extending obliquely downward, and the lower ends of the two parallel rods 34 are hinged to one of the clamping arms 8, and the connecting seat 31 and the two parallel rods 34 on the corresponding side and the clamping arm 8 form a parallel four-bar linkage mechanism, and the parallel four-bar linkage mechanism structures on both sides of the connecting seat 31 are symmetrical; the two latches 7 are fixed on the opposite side walls of the two clamping arms 8, and the two parallel four-bar linkage mechanisms are transformed shape, the direction of the latch 7 will not change; the clamping mechanism is equipped with an elastic member that drives the two clamping arms 8 to approach each other; in the above structure adopted by the clamping mechanism, the two clamping arms 8 can move away from and approach each other, thereby being able to clamp the upper covers of different types of embedded navigation lights, and at the same time, the directions of the two latches of the two clamping arms 8 will not change during the spacing adjustment process, thereby being able to precisely match with the tool holes on both sides of the upper cover, so as to ensure that the clamping mechanism can exert a good clamping effect on the upper covers of different types of embedded navigation lights; Furthermore, the elastic member can be a tension spring installed between two parallel four-bar linkages, or installed between each parallel four-bar linkage and the connecting seat 31; a more preferred way is that a protrusion 32 is reserved on each of the two symmetrical parallel rods 34 located on both sides of the connecting seat 31, and the protrusion 32 is located inside the connecting seat 31. The elastic member is a spring 33 installed inside the connecting seat 31, and the spring 33 is used to apply force to the two protrusions 32 to drive the two clamping arms 8 to move closer to the middle, thereby reducing the number of accessories exposed to the outside of the clamping mechanism and improving the compactness of the clamping mechanism.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
