Description

Shock absorption and danger signal notification device for safety accident prevention in logistics work environment}

The present invention relates to a technology capable of informing a danger signal within a logistics work environment, and more particularly, an accident in which an impact is applied by sounding an alarm sound when an impact is applied due to a collision of a vehicle within the logistics work environment It relates to a shock absorption and danger signal notification device for preventing safety accidents in a logistics work environment that can promote the safety of drivers as well as people around them at the point of occurrence.

In general, in a logistics work environment, a work vehicle (eg, a forklift) for transporting goods is operated, and an elastic panel for shock absorption is installed as a safety device on a pillar, beam, or wall of a building.

However, the conventional safety device applies only a simple buffering function, and only prevents damage to the contact part due to light impact. Moreover, since it is virtually impossible to fully recognize dangerous situations in the surroundings other than the driver, safety accidents due to carelessness frequently occur even in preventable situations.

For example, in a state where a bumper structure is installed on a pillar of a building where transport and unloading equipment such as a forklift enters and exits, and at a predetermined position at the top of the entrance or the bottom of the wall, even if the transport and unloading equipment contacts the bumper structure, the operator recognizes the contact state In many cases, it was not possible to do so, and accordingly, the conventional bumper structure was frequently seriously damaged due to a single impact.

In other words, when cargo is loaded on transport and unloading equipment such as forklifts and entering and exiting the workplace, the worker (driver) moves the work space in a state where forward observation is impossible because the operator (driver) cannot sufficiently secure the front view due to the loaded cargo. It frequently happens that the vehicle is operated with the load lifted without being conscious of the height of the forklift truck, which frequently damages the building as well as the body of the forklift truck entering and exiting the workplace.

1 to 7, a shock absorbing and danger signal notification device for preventing safety accidents in a logistics work environment according to an embodiment of the present invention includes a case member 10, an elastic ball 20, and a cover member. (30), including a whistle member (40).

The case member 10 is a soft polyurethane material having elasticity and is attached or coupled to an adherend forming various shapes in a logistics work environment, and has a hollow space S1 with one side or both sides opened. will be.

The adherend is, as shown in the attached FIGS. 1 to 6, for the purpose of preventing vehicle collision on the inner and outer walls of the building or the upper wall of the door of the building in the logistics work environment including the pillar 101 and the beam 102. In addition, as shown in the attached FIGS. 8 to 10, 15 and 16, for the purpose of safety facilities installed on the road surface 103 in the logistics work environment, or the attached FIGS. 11 and 12 As in, it can be installed in the form of a safety facility installed on the vehicle 104 traveling on the road in the logistics work environment, and as another embodiment, as shown in the accompanying FIGS. 13 and 14, the road in the logistics work environment It can be implemented in the form of being applied to the bar-shaped road elastic rod 105 installed on the road surface at the confluence point or center line boundary.

In other words, the case member 10 is preferably attached to or coupled to the pillar 101, the beam 102, the road surface 103, the vehicle 104, and the rod-shaped road elastic rod 105. It can be manufactured in various shapes.

That is, as shown in the accompanying FIGS. 1 to 6, the case member 10 having a hollow space S1 is the inside of a building in a logistics work environment including the pillar 101 and the beam 102. It is made of a buffer bumper structure for vehicle collision warning that is attached or coupled to a certain length in the vertical direction while maintaining a shape that partially surrounds the corner of the pillar 101 or beam 102 on the wall or outer wall surface, or when an impact is applied It will be manufactured as a buffer bumper structure for vehicle collision warning that is installed at a certain distance from the pillar 101 or beam 102 while both ends are coupled to the distance maintenance bracket (BT) to enable elastic recovery while absorbing impact in stages. It could be.

Here, at the center of the case member 10, as exemplarily shown in FIG. 5, a carbon rod 50 for preventing rigidity, restoring force and sagging along with the elastic ball 20 is provided in the longitudinal direction of the case member ( 10), and both ends of the carbon rod 50 can be fixed by the cover member 30.

Therefore, the case member 10 according to an embodiment of the present invention is installed in a pillar 101 of a building where transport and unloading equipment such as a forklift enters and exits, a beam 102 at the top of the entrance, or a predetermined position at the bottom of the wall When the handling equipment approaches the case member 10 excessively and is pressed with a certain load beyond a light contact state, a warning signal is generated to the driver through the whistle member 40, and the pillar 101 and/or Or it is possible to prevent serious damage to the beam 102.

In other words, at a logistics work site, when loading cargo on transport and unloading equipment such as forklifts and entering and exiting the work site, the front view of the worker (driver) is not sufficiently secured due to the loaded cargo, so the front view is impossible, and the height of the door is not conscious. Since it is a frequent situation to operate in a state where the load is lifted, damage to the building as well as the body of the forklift entering and exiting the workshop often occurs. will be.

At this time, the case member 10 installed in the width direction at the top of the entrance door of the building in the logistics work environment is relatively frequently in contact with transport and unloading equipment that loads cargo and enters and exits the workplace, so even by the first collision Damage to the structure may occur, and therefore, it is preferable to install the case member 10 so that both ends are supported by the brackets BT for maintaining distance so that direct contact with the structure does not occur during the first impact.

The bracket (BT) for maintaining such a distance keeps the case member 10 at a certain distance from the upper beam 102 of the door, and therefore, the transport and unloading equipment loaded with cargo is connected to the case member 10 and 1 When a car collides, the case member 10 is pressed and deformed until it touches the wall surface, and at this time, the case member 10 through the whistle member 40 installed on the cover member 30 supporting both ends It is to sound an alarm according to the change in the internal air pressure of (10), so it is possible to prevent damage to the building by quickly avoiding the contact state.

(Second embodiment)

8 shows a case in which the shock absorbing and danger signal notification device for preventing safety accidents in a logistics work environment according to the present invention is applied to an emergency braking facility.

As shown in FIG. 8, the case member 10 having a hollow space S1 is installed to prevent a dangerous situation due to an unexpected brake failure in a work vehicle operating in a logistics environment. As an emergency braking facility, it is a substitute for an anti-impact tank that protects the vehicle and the driver, and it can be manufactured as a unit block for anti-impact combined with a plurality of units.

At this time, the outer skin member 10, which is a unit block for preventing impact, which is coupled in plurality, can be connected and coupled while a pair of steel wires 60 parallel to the lower portion continuously penetrate, and the steel wires 60 can be connected to a plurality of It serves to regulate the unit blocks so that they do not escape to the outside in the event of an emergency collision contact with the vehicle, and at the same time, it is possible to buffer and suppress the pushing of the unit blocks step by step and gradually.

Here, the shock-proof unit block body constituting the case member 10 absorbs shock without difficulty even if the front surface is made more angular than other products, and as a result, it is easy to avoid impact and many impacts even when colliding at an oblique angle. It is desirable to be able to absorb.

In addition, regardless of the angle at which the collision occurs, the internal pressure changes according to the degree of pressing of the case member 10, and the whistle member 40 generates an alarm sound. Because it is made of urethane material, it can have characteristics of excellent resilience and less damage to the colliding body or superficial body after impact.

The case member 10 installs the photovoltaic module 71 on the upper surface of the block body located in the frontmost position, and the impact situation is alerted by an impact sensor or the like accommodated in the control unit 72 installed together with it, or It is possible to expect the effect of emergency response as well as the prevention of accidents by enabling prompt notification to the surroundings with luminous lighting.

(Third embodiment)

Attached FIG. 11 also shows a case in which the shock absorbing and danger signal notification device for preventing safety accidents in the logistics work environment of the present invention is applied to a vehicle bumper structure for protecting a working vehicle and a driver.

As shown in FIG. 11, the case member 10 having a hollow space S1 protects a work vehicle and a worker or driver in a logistics work environment and may be manufactured as a buffer bumper structure for a vehicle.

At this time, the case member 10 having a hollow space portion S1, which is the buffer bumper structure for a vehicle, is molded to have a pipe structure maintaining a standardized cross section or an irregular cross section, and has an entrance open on at least one side ( 11), or can be made of a plate-shaped structure having a volume of a certain thickness, and the opened inlet 11 can be sealed with the cover member 30 forming the plate shape.

In addition, a separate bracket 12 for coupling with the vehicle 104 may be embedded in the case member 10 having the hollow space S1 as the vehicle bumper structure.

The case member 10 in the form of a tube having a hollow space S1 can replace the energy absorber and bumper cover assembly sequentially coupled together with a back beam structure provided to support a normal vehicle bumper. As shown in FIG. 12, it is attached to the corner of a normal vehicle bumper or the end of a door and elastically absorbs the impact force upon contact impact with a doorknob and at the same time generates an alarm sound through the whistle member 40 to prevent damage to the vehicle. This could alert the driver.

At this time, since the case member 10 and the elastic ball 20 inserted therein are made of a soft polyurethane material having excellent elasticity, the restoring force is excellent, and thus the case member 10 is severely damaged. As long as it is not a collision, it can be used continuously without replacement work.

(Fourth embodiment)

Attached FIG. 13 also shows a case in which the shock absorbing and danger signal notification device for preventing safety accidents in a logistics work environment according to the present invention is applied to a rod-type road elastic bar.

As shown in FIGS. 13 and 14, the case member 10 having a hollow space S1 is attached to or coupled to the lower end of the rod-shaped road elastic rod 105.

That is, the case member 10 is formed in the form of a reinforcing rib to have the hollow space S1 from the bottom to the top of the bar-shaped road elastic bar 105 up to 1/5 of the total height, , The elastic ball 20 may be configured to be filled in the space S1 as well as the outer space S2 of the space S1.

In addition, a support shaft installation hole 13 fixed to the road surface with an anchor bolt or the like may be formed at the center of one end of the case member 10 attached to or coupled to the lower portion of the rod-shaped road elastic rod 105.

Here, the rod-shaped road elastic rod 105 is installed at the junction of the road or at the center line boundary to suppress the rapid entry of the vehicle, so the elastic ball 20 at the lower end of the rod-shaped road elastic rod 105 When applying the case member 10 having the hollow space portion S1 to be filled, the case member 10 is pressed in one direction when the upper portion of the rod-shaped road elastic rod 105 is bent by an external force. As it turns, it is possible to generate an alarm sound through the whistle member 40, and when the external force is removed, the cross section is quickly restored by the elastic ball 20, and the rod-shaped road elastic rod 105 moves to its original boundary. It is possible to perform the display function again.

(Fifth embodiment)

Attached FIG. 15 also shows a case where the shock absorbing and danger signal notification device for preventing safety accidents in a logistics work environment according to the present invention is applied to a speed bump structure.

Meanwhile, as shown in FIGS. 15 and 16, the case member 10 having a hollow space S1 is fixed to the road surface 103 with anchor bolts 300 while forming a radial tube shape. It can be manufactured to be accommodated inside the speed bump structure.

That is, since conventional speed bumps made of PVC material are stipulated not to exceed a maximum height of 7 to 10 cm in consideration of the impact applied to the vehicle and the degree of shaking of the vehicle, In this case, there are frequent cases of driving without significantly reducing speed, and because it is recognized as a relatively low height, the visual effect is limited, and damage to the vehicle and bumps occurs when driving at high speed.

However, since the speed bump structure of the shock absorbing and danger signal notification device for preventing safety accidents in the logistics work environment of the present invention is made of soft polyurethane material having excellent elasticity, it is about 15 cm that can be perceived as a visual threat to the driver. Even if the height of is maintained, it does not affect safe driving as the operation of being elastically pressed and then elastically restored when a vehicle passes is repeated.

Moreover, when manufactured by adding the height of the case member 10, the sloshing occurs through a change in the position of the filled elastic ball 20, and the sloshing is transmitted to the vehicle as it is, so when the vehicle runs at high speed, the tire While passing the speed bump, the driver can experience temporary instability through the sloshing, and even a driver who repeatedly travels the same section can be induced not to drive by increasing the driving speed after one experience.

The elastic ball 20 applied to the first to fifth embodiments is a small circular ball (10 to 80 mm) inside the hollow space S1 provided in the case member 10. Depending on the size, countless amounts can be filled.

At this time, the elastic ball 20 is a sphere or cube-shaped elastic structure having a certain space on the inner surface, inside which the elastic ball 20 is scattered as an obstacle when the case member 10 is damaged. To prevent this, a fluid (not shown) imparting weight and impact resistance may be filled, and the fluid may be antifreeze, water, or carbon dioxide gas.

Here, when the elastic ball 20 is filled with the antifreeze or water, the elastic ball 20 filled with the antifreeze or water is the upper part of the hollow space S1 in the case member 10. In this case, when an external force is applied to the case member 10 according to the weight of the elastic ball 20, a lot of contraction occurs in the middle part that receives a direct collision, so that the case member 10 that can prevent damage.

In addition, the reason for filling the elastic ball 20 with carbon dioxide gas is that there is a risk of fire when an external force strong enough to damage the case member 10 is applied to the case member 10, in which case the case Since the elastic ball 20 injected into the hollow space S1, which is the inside of the member 10, may also be damaged, the carbon dioxide gas filled in the elastic ball 20 may scatter and extinguish a fire. it is meant to be

Meanwhile, in the elastic balls 20 accommodated in at least one space S1 of the case member 10, the elastic balls 20 accommodated and disposed in the middle region of the space S1 The inside may be filled with air of a certain volume (eg, approximately 1/3) to effectively absorb external impact and minimize damage to the adherend by using elastic repulsive force.

In other words, it is not necessary to fill the inside of all the elastic balls 20 with antifreeze, water or carbon dioxide gas. For example, in the case of the anti-shock tank illustrated in FIG. 8, in order to increase stability due to its weight, the upper and lower 30 cm sections fill the elastic ball 20 into which coolant is inserted, and the middle part subjected to direct collision causes a lot of contraction. Therefore, when an excessive collision occurs to the extent that the case member 10 is damaged, carbon dioxide gas to help extinguish a fire can be inserted.

The cover member 30 is coupled to one side or both sides of the opening of the case member 10 filled with the elastic ball 20, so that the elastic ball 20 is filled in the case member 10 in a hollow state. By sealing the space portion (S1), it includes a closing plate 31, a fixing plate 32, and a reinforcing plate 33.

The closing plate 31 covers one side or both sides of the opening of the case member 10, and the fixing plate 32 extends perpendicularly to one surface of the closing plate 31 and can be coupled to the adherend. And, the reinforcing plate 33 is superimposed and assembled on the outside of the fixing plate 32 so that the fixing plate 32 is supported by the adherend.

Here, the whistle member 40 penetrating the closing plate 31 is installed on the closing plate 31, and the fixing plate 32 can be fixed to the adherend with fastening bolts 200. .

The whistle member 40 is formed to be exposed to the outside from the closing plate 31 included in the cover member 30, which is hollow when an impact is applied to the case member 10, the space portion S1 ) to generate an alarm sound due to the air moving through the elastic balls 20 according to the change in volume.

That is, as shown in the accompanying FIG. 7, the whistle member 40 does not generate an alarm sound when the air movement is less than a certain amount due to an impact pressure of less than a certain amount applied to the case member 10, and the case member 10 A first air channel (41) having a first length (L1) and a first width (W1) so as to generate an alarm sound when a certain amount of air moves due to a certain amount or more of impact pressure applied to (10), the first A second air passage 42 having a second length L2 shorter than the length L1 and a second width W2 lower than the first width W1, and branching from the first air passage 41 It is to include a whistle flow path (43).

As such, the danger signal notification device according to the embodiment of the present invention, as shown in the accompanying FIGS. While attaching or combining), at least one or more elastic balls 20 are filled in the hollow space S1 sealed by the cover member 30 in the case member 10, and at the same time the whistle member 40 ) was applied.

Then, when a collision accident occurs with the adherends 101, 102, 103, 104, 105 in the logistics work environment, the case member 10 attached or coupled to the adherends 101, 102, 103, 104, 105 ), and according to the external force, the volume of the hollow space S1 inside the case member 10 is changed.

At this time, the elastic ball 20 filled in the space part (S1) moves according to the volume change of the space part (S1), and between the elastic balls (20) according to the movement of the elastic ball (20). As air movement occurs through, the moving air is exhausted to the outside through the whistle member 40.

Then, when a collision accident of a work vehicle operating in the logistics work environment occurs, the shock caused by the collision is not only the case member 10 but also the space portion S1 formed in the hollow state formed in the case member 10. Whistle member 40 applied to the case member 10 and can protect the driver from impact while being continuously multi-stage absorbed by the volume change and the elastic ball 20 filled in the space S1 While generating an alarm sound due to the air exhausted to the outside, the safety of the people around the accident point where the impact is applied is promoted by allowing nearby workers to recognize the state of the collision accident through the alarm sound. It can.

In the above, the technical concept of the shock absorption and danger signal notification device for preventing safety accidents in the logistics work environment of the present invention has been described together with the accompanying drawings, but this is an exemplary description of the most preferred embodiment of the present invention and limits the present invention. It is not.
