Description

Technical Field

[0001] This invention relates to the field of protective devices, and more particularly to an airport engineering safety protection device and its installation method. Background Technology

[0002] During airport construction, warning devices are needed to remind pedestrians to stay away. One commonly used warning device is the no-entry sign. For example, patent CN204884488U discloses a no-entry sign for airports, including LED lights, a frame, a panel, rollers, a rotating fixing frame, and legs. The panel is installed on the frame, and two legs are connected to the bottom of the frame. An X-shaped LED light is installed inside the panel. Rollers are installed under the legs, and the rotating fixing frame is hinged to the rollers. This invention installs rollers under the legs and adds a rotating fixing frame to the rollers. When the sign needs to be moved, the rotating fixing frame is flipped upwards to push it, making the sign roll and facilitating transportation. When the sign is moved to the desired location, the rotating fixing frame is flipped downwards, contacting the ground to fix the sign and prevent it from moving. This invention is convenient to use. Furthermore, it uses LED lights as the light-emitting device, which has the advantages of stable operation, long lifespan, energy saving, and environmental friendliness.

[0003] Alternatively, warning tape can be used to alert pedestrians to stay away. For example, patent CN109650195A discloses a warning tape device, including a warning tape; a storage box with a rotating shaft inside, the warning tape being placed inside the storage box and wound around the rotating shaft, and the storage box having a tape release port for releasing the warning tape; and a driver, located outside the storage box, detachably connected to the rotating shaft and used to drive the rotating shaft to rotate. After the power construction is completed, the driver is connected to the rotating shaft, and the driver is activated to drive the rotating shaft to rotate, thereby winding the warning tape into the storage box through the tape release port and onto the rotating shaft, achieving automatic retrieval and storage of the warning tape. Compared with manual winding and retrieval, this method improves the retrieval speed and construction progress, and also reduces labor costs.

[0004] However, both of these devices have their own advantages and disadvantages. No-entry signs are relatively stable and not easily damaged, but they cannot directly block pedestrians. Warning tapes can block pedestrians, but they are not stable enough and are easily damaged or fall off due to wind and sun. How to combine their advantages to achieve a better protective effect has become an urgent problem to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide an airport engineering safety protection device and its installation method to solve the above-mentioned technical problems.

[0021] Example 1

[0022] like Figure 1-3As shown, an airport engineering safety protection device includes a base plate 5; a base 3, with the base 3 fixedly mounted on the top surface of the base plate 5; a prohibition sign 4, with the prohibition sign 4 fixedly mounted on the front of the base 3; a sleeve 2, which is fitted onto the outside of the base 3 and is slidably connected to the base 3 vertically. A limiting screw 22 is threadedly connected to the side of the base 3; a notch 6 is provided on the right side of the sleeve 2. When it is necessary to display the prohibition sign 4, the sleeve 2 is pushed upward, and then the limiting screw 22 is threadedly connected to the base 3, so that the limiting screw 22 is positioned below the sleeve 2 and locks the sleeve 2, preventing the sleeve 2 from moving downward.

[0023] It also includes: a groove 24, which is provided on the top front of the base 3; a rotating shaft 16, which is disposed within the groove 24, and teeth are provided on the surface of the rotating shaft 16 along its circumference; a first drive shaft 18, on which the rotating shaft 16 is fixedly sleeved; a fixed seat 17, which is provided on both the left and right sides of the first drive shaft 18, through which the first drive shaft 18 passes and is rotatably connected to the fixed seat 17, and the fixed seat 17 is fixedly connected to the groove 24; and a rack 1, which is fixed inside the sleeve 2 and meshes with the rotating shaft 16. During the up-and-down pushing of the sleeve 2, the rack 1 can move up and down synchronously, causing the rack 1 to drive the rotating shaft 16 meshing with it to rotate.

[0024] It also includes: an upper sprocket 21, which is fixedly sleeved on the right end of the first drive shaft 18; a lower sprocket 14, which is located below the upper sprocket 21 and is connected to the upper sprocket 21 by a chain 7; a second drive shaft 11, on which the lower sprocket 14 is fixedly sleeved; a guide rail 13, on which the left end is fixedly connected to the right end of the base plate 5; a slide groove 12, on which the top of the guide rail 13 is provided; a fixing block 15, which is fixed on the left side of the slide groove 12, and the second drive shaft 11 passes through the fixing block 15 and is rotatably connected to the fixing block 15; and a slider 10, which is sleeved on the second drive shaft 11, threadedly connected to the second drive shaft 11, and slidably connected within the slide groove 12. A fixed rod 9 is fixed to the top of the slider 10; a warning tape 8 is fixedly connected to the fixed rod 9 at one end; a connecting shaft 20 is fixedly connected to the connecting shaft 20 at the other end; and a bearing 19 is fixedly connected to the connecting shaft 20 at its inner ring and to the upper sprocket 21 at its outer ring. When the rotating shaft 16 rotates, it drives the second transmission shaft 11 to rotate synchronously through the first transmission shaft 18, the upper sprocket 21, the chain 7, and the lower sprocket 14 in sequence. The second transmission shaft 11 drives the slider 10 and the fixed rod 9 to reciprocate, causing the warning tape 8 to be retracted or unfolded.

[0025] Working principle: When using this device, move the sleeve 2 upward to expose the prohibition sign 4, and then thread the limit screw 22 to the base 3 to lock the sleeve 2 and prevent it from moving downward. During the upward movement of the sleeve 2, the rack 1 moves upward synchronously, causing the rack 1 to drive the rotating shaft 16 meshing with it to rotate. The rotating shaft 16 drives the upper sprocket 21 to rotate through the first transmission shaft 18. The upper sprocket 21 drives the lower sprocket 14 to rotate through the chain 7. The lower sprocket 14 drives the slider 10 to move to the right through the second transmission shaft 11. The slider 10 drives the fixed rod 9 to move to the right synchronously, so that the warning tape unfolds and has an obstructive effect.

[0026] When warnings and barriers are no longer needed, remove the limit screw 22, move the sleeve 2 down, and cause the rack 1 to drive the rotating shaft 16 to rotate in the opposite direction, thereby causing the fixing rod 9 to move in the opposite direction and retract the warning tape 8.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
