Description

Technical Field

[0001] The present invention relates to a technology capable of issuing danger signals within a logistics work environment. More specifically, it relates to a shock-absorbing and danger signal alarm device for preventing safety accidents in a logistics work environment, which can issue an alarm when a vehicle collides and is impacted, thereby ensuring the safety of the driver and surrounding personnel at the accident site who are impacted. Background Art

[0002] Generally speaking, in a logistics work environment, work vehicles (such as forklifts) are used to transport items, and safety devices such as shock-absorbing elastic panels are installed on the columns, beams, or walls of buildings.

[0003] However, previous safety devices only provided a simple cushioning function, preventing damage to the contact parts caused by minor impacts. In the event of a collision, they were unable to confirm the extent of the impact to the driver or staff. More importantly, other people besides the driver were unable to fully perceive the dangerous situation. As a result, safety accidents frequently occurred due to negligence, even in preventable situations.

[0004] For example, when bumper structures are installed at predetermined locations above pillars, entrances, or below walls of buildings where forklifts and other handling equipment enter and exit, even if the equipment comes into contact with the bumper structure, the driver often cannot sense the contact. As a result, conventional bumper structures frequently suffer severe damage from a single impact.

[0005] In other words, when using forklifts and other handling and loading equipment to load goods in and out of the work site, the load blocks the worker's (driver's) field of vision, causing them to move in the work space without being able to see what's ahead. Furthermore, it frequently happens that the load is lifted while driving without paying attention to the entrance and exit heights. As a result, damage to the forklift bodies and buildings entering and leaving the work site often occurs. Summary of the Invention

Figure 6The present invention is an embodiment of a safety device provided on a beam constituting an inner wall of a building, and is a schematic cross-sectional view as viewed from the front. Figure 7 This is a schematic cross-sectional view showing the structure of a whistle component as one embodiment of the present invention.

[0053] Refer to the attached Figures 1 to 7 According to one embodiment of the present invention, a shock-absorbing and danger signal alarm device for preventing safety accidents in a logistics work environment includes: a shell component 10, an elastic ball 20, a cover component 30, and a whistle component 40.

[0054] The shell component 10 is made of elastic soft polyurethane material, and is attached or combined to various attached objects in a logistics working environment. It has a space portion S1 that is open on one side or both sides and is hollow inside.

[0055] The attached object, such as Figures 1 to 6 As shown, it can be set on the inner and outer walls of buildings or the walls above the entrances and exits of buildings in the logistics working environment including the pillars 101 and the beams 102 for vehicle collision prevention. In addition, as shown in FIG. Figures 8 to 10 、 Figure 15 and Figure 16 As shown, it can be used to set up safety facilities on the road surface 103 in the logistics work environment, or as Figure 11 and Figure 12 As shown, the safety facilities are provided on a vehicle 104 traveling on a road in a logistics work environment. As another embodiment, the safety facilities can be applied to Figure 13 and Figure 14 The embodiment shown is realized in the form of a rod-shaped road elastic rod 105 provided on the road surface at the confluence point or center line boundary of the road in the logistics working environment.

[0056] In other words, the housing member 10 can be manufactured into various shapes suitable for being attached to or combined with the pillars 101 and beams 102 , the road surface 103 , the vehicle 104 , and the rod-shaped road elastic rod 105 .

[0057] That is, Figures 1 to 6 As shown, the shell component 10 having a hollow space portion S1 can be made into a buffer bumper structure for vehicle collision alarm, which maintains a shape of partially wrapping the corners of the column 101 or beam 102 on the inner wall or outer wall of a building in a logistics working environment including the column 101 and the beam 102, and is attached or combined with a specified length in the upper and lower directions; or it can be made into a buffer bumper structure for vehicle collision alarm, which can absorb impacts at multiple levels and elastically recover when an impact is applied, is connected at both ends by a distance-maintaining bracket BT, and is set at a specified distance from the column 101 or beam 102.

[0058] Among them, such as Figure 5 As shown, a carbon rod 50 for preventing rigidity and restoring force together with the elastic ball 20 and preventing deflection can be inserted into the center of the shell part 10 along the length direction and across the shell part 10, and both ends of the carbon rod 50 can be fixed by the cover part 30.

[0059] Therefore, according to one embodiment of the present invention, the shell component 10 is set at a predetermined position on a pillar 101 of a building where forklifts and other handling and loading equipment enter and exit, a beam 102 above an entrance and exit, or below a wall. When the loading and unloading equipment approaches the shell component 10 too close, exceeds a light contact state, and is squeezed by a specified load, an alarm signal is sent to the driver through the whistle component 40, thereby preventing serious damage to the pillar 101 and / or beam 102.

[0060] That is, at a logistics work site, when forklifts and other handling and loading equipment are used to load goods in and out of the work area, the load blocks the worker's (driver's) field of vision, resulting in the worker (driver) frequently not paying attention to the height of the entrance and exit and lifting the load to drive when the worker is unable to observe the front. As a result, damage to the forklift body and buildings entering and leaving the work area often occurs, which can be prevented by the alarm sound emitted by the whistle component 40.

[0061] At this time, the shell component 10 arranged along the width direction above the entrance and exit of the building in the logistics work environment has a high frequency of contact with the handling and loading and unloading equipment for loading goods into and out of the work site. Therefore, damage to the structure may occur even in the first collision. Therefore, in order to prevent direct contact with the structure in the first impact, it is preferably supported at both ends of the shell component 10 by a distance maintaining bracket BT for installation.

[0062] This distance-maintaining bracket BT keeps the outer shell component 10 at a specified distance from the beam 102 above the entrance and exit. Therefore, when the loading and unloading equipment carrying the cargo collides with the outer shell component 10 for the first time, the outer shell component 10 is squeezed and deformed before it contacts the wall. At this time, the whistle component 40 provided on the cover component 30 supporting both ends of the outer shell component 10 emits an alarm according to the change in the air pressure inside the outer shell component 10, thereby quickly avoiding the contact state and preventing damage to the building.

[0063] (Second embodiment)

[0064] Figure 8 It shows the situation in which the shock absorption and danger signal alarm device for preventing safety accidents in the logistics working environment of the present invention is applied to emergency braking facilities.

[0065] like Figure 8 As shown, the shell component 10 having a hollow space portion S1 is an emergency braking facility used to prevent dangerous situations caused by unexpected brake failures in working vehicles traveling in a logistics environment. It is an alternative to the anti-collision tank body that protects the vehicle and the driver, and can be made into multiple anti-collision unit blocks that are combined with each other.

[0066] At this time, the lower part of the outer skin component 10, which is a plurality of mutually combined anti-collision unit blocks, can be continuously penetrated and connected by a pair of parallel steel wire ropes 60. The steel wire ropes 60 restrain the plurality of unit blocks from detaching outwards when the vehicles come into emergency collision contact, and can also buffer and suppress the movement of the unit blocks in a multi-level and gradual manner.

[0067] Among them, the anti-collision unit block constituting the shell component 10 is preferably made with its front edge sharper than that of other products so that there is not much problem in shock absorption, thereby making it easy to avoid before collision and being able to absorb a lot of impact even if it collides at an oblique angle.

[0068] Moreover, no matter from which angle the collision occurs, the internal air pressure will change according to the degree of squeezing of the shell component 10, and an alarm sound will be emitted from the whistle component 40. Moreover, since it is made of a soft polyurethane material with excellent elasticity, after being impacted, the damage to the colliding body or the collided body is small, and it has excellent recovery ability.

[0069] The shell component 10 is provided with a solar module 71 on the upper surface of the block located at the front, and through the impact sensor housed in the control unit 72 provided therewith, it can quickly issue an impact alarm to the surroundings through alarm voice or light illumination, thereby expecting the effect of preventing accidents and emergency treatment.

[0070] (Third embodiment)

[0071] Figure 11 It also shows the case where the shock absorption and danger signal alarm device for preventing safety accidents in a logistics working environment of the present invention is applied to a vehicle buffer bumper structure for protecting working vehicles and drivers.

[0072] like Figure 11 As shown, the shell member 10 having the hollow space portion S1 can also be made into a vehicle buffer bumper structure in order to protect the working vehicle and the workers or drivers in the logistics working environment.

[0073] At this time, the shell component 10, which serves as the vehicle buffer bumper structure and has a hollow space portion S1, can be formed into a pipe structure maintaining a standardized cross-section or a hat-shaped structure having an irregular cross-section and providing an inlet 11 open on at least one side, or can be made into a plate-like structure with a volume of a specified thickness, and the open inlet 11 can be sealed by the cover component 30 formed into a plate shape.

[0074] Furthermore, as the vehicle impact bumper structure, a separate bracket 12 for coupling with the vehicle 104 may be incorporated in the shell member 10 having the hollow space S1 .

[0075] The housing member 10 having a hollow space portion S1 in a pipe shape can replace a rear beam structure provided for supporting a conventional vehicle bumper and an energy absorber and a bumper cover assembly that are sequentially combined, such as Figure 12 As shown, by being attached to the corner of a bumper or the end of a door for an ordinary vehicle, the impact force can be elastically absorbed when the door collides with the impact, and an alarm sound is emitted through the whistle component 40, thereby preventing vehicle damage while conveying a sense of vigilance to the driver.

[0076] At this time, the shell component 10 and the elastic ball 20 filled therein are made of a soft polyurethane material with excellent elasticity, and therefore have excellent recovery ability. Therefore, as long as the shell component 10 is not severely damaged by a collision, it can be continuously used without replacement.

[0077] (Fourth embodiment)

[0078] Figure 13 It also shows the situation where the shock absorption and danger signal alarm device for preventing safety accidents in a logistics working environment of the present invention is applied to a rod-shaped road elastic rod.

[0079] like Figure 13 and Figure 14 As shown, the housing member 10 having a hollow space S1 is attached or coupled to the lower end of the rod-shaped road elastic rod 105 .

[0080] That is, the outer shell member 10 may be formed to have a reinforcing rib configuration having the hollow space S1 at a point 1 / 5 of the total height from the bottom to the top of the rod-shaped road elastic rod 105, so that the elastic ball 20 can be filled in both the space S1 and the space S2 outside the space S1.

[0081] Furthermore, a support shaft installation hole 13 for fixing to the road surface by means of an anchor screw or the like may be formed at the center of one end of the housing member 10 attached to or coupled to the lower portion of the rod-shaped road elastic rod 105 .

[0082] Since the rod-shaped elastic road rod 105 is installed at a road junction or centerline boundary to prevent sudden entry of vehicles, when the outer shell 10 having a hollow space S1 filled with the elastic ball 20 is applied to the lower end of the rod-shaped elastic road rod 105, the outer shell 100 can bend the upper portion of the rod-shaped elastic road rod 105 in a unidirectional manner under the action of an external force, thereby sounding an alarm through the whistle component 40. After the external force is removed, the elastic ball 20 quickly restores its cross-section, allowing the rod-shaped elastic road rod 105 to resume its original boundary marking function.

[0083] (Fifth embodiment)

[0084] Figure 15 It also shows the application of the shock-absorbing and danger signal alarm device for preventing safety accidents in a logistics working environment of the present invention to a speed bump structure.

[0085] On the other hand, Figure 15 and Figure 16 As shown, the outer shell member 10 having the hollow space S1 can be manufactured in a radial pipe form and housed inside a speed bump structure fixed to the road surface 103 by anchor screws 300 .

[0086] Specifically, conventional speed bumps made of PVC are regulated to a maximum height of 7 to 10 cm, taking into account the impact and swaying effects on moving vehicles. Consequently, drivers frequently travel the same distance without significantly slowing down. Furthermore, their relatively low height limits their visual impact, and excessive speed can damage both the vehicle and the speed bump.

[0087] However, the speed bump structure of the shock-absorbing and hazard signal alarm device for preventing safety accidents in the logistics operation environment of the present invention is made of a soft polyurethane material with excellent elasticity. Even if it is maintained at a height of about 15 cm, which may pose a visual threat to the driver, it will repeat the elastic compression and rebound actions when the vehicle passes by, thereby not affecting safe driving.

[0088] In addition, if the height of the shell member 10 is increased during manufacturing, shaking will occur due to the change in position of the filled elastic balls 20, and the shaking will be directly transmitted to the vehicle. Therefore, when the vehicle is driving at high speed, the driver will experience temporary instability through the shaking when the tire passes through the speed bump. Even if the driver repeatedly travels back and forth on the same section of road, he will be guided not to increase the driving speed after experiencing it once.

[0089] The elastic balls 20 used in the first to fifth embodiments may be filled with numerous small round balls (10 to 80 mm) in size in the hollow space S1 provided in the housing member 10 .

[0090] At this time, the elastic ball 20 is an elastomeric structure in the shape of a ball or cube with a specified space on its inner surface. In order to prevent the elastic ball 20 from flying away as an obstacle when the outer shell component 10 is damaged, a fluid (not shown) that imparts a sense of weight and impact resistance can be filled inside it. The fluid can be antifreeze, water, or carbon dioxide gas.

[0091] Among them, when the elastic ball 20 is filled with the antifreeze liquid or water, the elastic ball 20 filled with the antifreeze liquid or water will be dropped into the upper and lower 30 cm intervals of the hollow space portion S1 in the outer shell component 10. In this case, according to the weight of the elastic ball 20, when the outer shell component 10 is subjected to external force, the middle part directly impacted will shrink significantly, thereby preventing damage to the outer shell component 10.

[0092] Furthermore, the reason for filling the elastic ball 20 with carbon dioxide gas is that when a strong external force is applied to the outer shell member 10 to damage the outer shell member 10, there is a concern that a fire may occur. In this case, the elastic ball 20 inserted into the hollow space S1 inside the outer shell member 10 may also be damaged. Therefore, the carbon dioxide gas filled in the elastic ball 20 is dispersed to extinguish the fire.

[0093] On the other hand, when at least one of the elastic balls 20 is accommodated in the space portion S1 of the shell component 10, a specified volume (for example, approximately 1 / 3) of air can be filled inside the elastic ball 20 accommodated in the middle area of the space portion S1 to effectively absorb external impacts and minimize damage to the attached object by utilizing elastic rebound force.

[0094] In other words, it is not necessary to fill the interior of all elastic balls 20 with antifreeze liquid or water or carbon dioxide gas. Figure 8 In the case of the anti-collision tank body shown in the example, in order to increase the weight to improve the sense of stability, the upper and lower 30 cm intervals are filled with elastic balls 20 inserted with cooling water, and the middle part directly affected by the impact will shrink more. Therefore, when an excessive collision occurs that damages the outer shell part 10, carbon dioxide gas can be inserted to help extinguish the fire.

[0095] The cover component 30 is combined with one or both open sides of the shell component 10 filled with the elastic ball 20 to seal the hollow space S1 filled with the elastic ball 20 in the shell component 10 , and includes an end panel 31 , a fixing plate 32 , and a reinforcing plate 33 .

[0096] The end panel 31 is used to cover the open side or both sides of the shell component 10. The fixing plate 32 extends orthogonally on one surface of the end panel 31 and can be combined with the attached object. The reinforcement plate 33 is folded and assembled on the outside of the fixing plate 32 so that the fixing plate 32 is supported on the attached object.

[0097] The whistle component 40 penetrating the end panel 31 is provided on the end panel 31 , and the fixing plate 32 can be fixed to the attached object by using fastening screws 200 .

[0098] The whistle member 40 is formed in a manner exposed to the outside on the end panel 31 included in the cover member 30. This is so that when an impact is applied to the outer shell member 10, the volume of the hollow space portion S1 changes, and an alarm sound is generated by the air moving between the elastic balls 20.

[0099] That is, Figure 7 As shown, in the whistle component 40, when an air movement of less than a specified amount occurs due to an impact pressure of less than a specified amount applied to the shell component 10, an alarm sound is not generated, and when an air movement of more than a specified amount occurs due to an impact pressure of more than a specified amount applied to the shell component 10, an alarm sound is generated. The whistle component includes a first air flow path 41 having a first length L1 and a first width W1, a second air flow path 42 having a second length L2 shorter than the first length L1 and a second width W2 lower than the first width W1, and a whistle flow path 43 branching from the first air flow path 41.

[0100] As described above, the danger signal alarm device of the embodiment of the present invention is as follows: Figures 1 to 16 As shown, the shell component 10 is attached or combined respectively on various attached objects 101, 102, 103, 104, and 105 in the logistics working environment. On the other hand, at least one elastic ball 20 is filled into the hollow space portion S1 sealed by the cover component 30 in the shell component 10, and the whistle component 40 is applied.

[0101] Then, when a collision accident occurs on the attached objects 101, 102, 103, 104, 105 in the logistics working environment, external force will be applied to the shell component 10 attached or combined with the attached objects 101, 102, 103, 104, 105, and, according to the external force, the volume of the interior of the shell component 10, that is, the hollow space S1, will change.

[0102] At this time, the elastic balls 20 filled in the space S1 will move as the volume of the space S1 changes. As the elastic balls 20 move, air will move between the elastic balls 20, and the moved air will be discharged to the outside through the whistle component 40.

[0103] Then, the impact caused by a collision accident of a work vehicle traveling in a logistics work environment will be continuously absorbed in multiple stages through the shell component 10 and the volume change of the hollow space portion S1 formed on the shell component 10, as well as the elastic ball 20 filled in the space portion S1, thereby protecting the driver from the impact. In addition, the whistle component 40 applied to the shell component 10 will generate an alarm sound due to the air discharged to the outside. Through the alarm sound, surrounding personnel can perceive the occurrence of the collision accident, thereby ensuring the safety of surrounding personnel at the accident site where the impact is applied.
