Description

Technical Field

[0001] The present invention relates to the technical field of forklifts, and in particular to a forklift with high safety. Background Art

[0002] Forklifts are industrial handling vehicles, which refer to various wheeled handling vehicles that load, unload, stack and transport palletized goods over short distances. They are often used to transport large objects in storage, usually powered by fuel engines or batteries. Industrial handling vehicles are widely used in ports, stations, airports, freight yards, factory workshops, warehouses, circulation centers and distribution centers, etc., to load, unload and transport palletized goods in cabins, carriages and containers, and are essential equipment for pallet transportation and container transportation.

[0003] The use environment of forklifts is relatively complex. When reversing, it is often necessary to take into account both the front and the back to prevent hitting people when reversing. However, due to the obstruction of the forklift body, the operator's vision is blocked when reversing. If the forklift continues to reverse when there are people behind, it is very easy to accidentally injure others. Even if the forklift is checked around before reversing, pedestrians will inevitably enter the reversing range of the forklift. In order to prevent accidental injury to others, a reversing buzzer is often installed on the forklift to warn people to stay away from the operating range of the forklift, so as to ensure that the forklift will not accidentally injure others. However, forklifts often start to reverse suddenly, and the elderly with limited mobility react slowly. When the buzzer sounds, they often have no time to dodge, which can easily cause danger. In addition, the buzzer is often louder to warn people. During the operation of the forklift, it needs to move forward and backward continuously. The frequency of use is high, which has a greater impact on the surrounding residents. Summary of the invention

[0004] The purpose of the present invention is to provide a forklift with high safety. The forklift with high safety is provided with a safety warning area. Not only is the range of the safety warning area adjustable, but it will not affect the sight of the operator and will not affect the people living nearby due to excessive noise.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings:

[0027] like Figures 1 to 6 As shown, a forklift with high safety includes a forklift body, and the forklift body includes a carport 11. Warning lights 2 are installed at the middle positions of the left wall, the right wall and the rear wall of the top of the carport 11. The light projected by the warning lights 2 is a straight-line projection warning line 4, and the projection warning lines 4 projected by the three warning lights 2 are combined into a projection warning area 41 with three frames, and the forklift body is in the projection warning area 41. During the use of the forklift body, the projection warning area 41 serves as a warning to pedestrians passing by, so as to prevent pedestrians from accidentally entering the projection warning area 41, and further prevent the forklift body from causing harm to pedestrians when turning or reversing due to the negligence of the operator.

[0028] The warning light 2 includes a lamp housing 21. The lamp housing 21 is made of die-cast aluminum metal material, which can not only dissipate the heat inside the lamp housing 21, but also enhance the strength of the lamp housing 21, protect the internal parts from damage, and make the warning light 2 more stable and reliable. The lamp housing 21 is in the shape of an elongated strip, and the shape of the warning line is fixed in the shape of an elongated strip. A lens portion 22 is provided inside the lamp housing 21. The lens portion 22 is two ellipsoidal structures that are closely adjacent and symmetrically arranged along the length direction of the lamp housing. A wiring harness integrated board 24 is provided on the side of the lens portion 22 away from the warning light 2. The wiring harness integrated board 24 is used to drive and carry the LED light source. The LED light source is two rows of LED lamp beads 23 arranged and symmetrically arranged along the length direction of the lamp housing. Each row of LED lamp beads 23 includes three LED lamp beads 23 arranged along the length direction of the lamp housing. A breathing hole 241 is provided on the harness integrated board 24, the breathing hole 241 is connected to the lamp housing 21, and a breathable cap 30 is provided at the place where the lamp housing 21 is connected to the breathing hole 241. The breathable cap 30 is composed of three parts: an outer shell, a rubber sleeve and a waterproof breathable membrane. The three parts work together to have the function of being breathable and waterproof. After the warning light 2 is lit, the temperature in the inner cavity of the lamp housing 21 increases, the air expands, and the excess air is discharged from the breathable cap 30; after the warning light 2 is turned off, the temperature in the inner cavity of the lamp housing 21 decreases, the air contracts, and the outside air enters from the breathable cap 30, ensuring that the internal pressure of the lamp is consistent with the external pressure, and the internal parts of the lamp will not be damaged due to pressure problems.

[0029] Mounting holes 31 are provided on both sides of the warning light 2, and a U-shaped hinge seat 29 is connected to the middle part of the top side wall of the carport 11. Both sides of the U-shaped hinge seat 29 are bolted to the mounting holes 31 respectively, and the warning light 2 is rotated along the straight line where the two mounting holes 31 are located as the rotating axis. After adjusting to the required angle, the angle between the warning light 2 and the top side wall of the carport 11 is fixed by tightening the bolts, and the change of the projected warning area 41 is completed. The range of the projected warning area 41 of the three frames is adjustable. When in use, the range of the projected warning area 41 can be adjusted according to the driving speed of the forklift body or the surrounding environment. When the driving speed of the forklift body is faster, the range of the projected warning area 41 is appropriately expanded, and when the driving speed of the forklift body is slower, the range of the projected warning area 41 is appropriately reduced.

[0030] A heat sink 25 is also provided inside the lamp housing 21. A breathing hole 241 passes through the heat sink 25 and is connected to the lamp housing 21. The heat sink 25 is arranged around the bottom and surroundings of the wiring harness integrated board 24 to guide the heat emitted by the LED lamp beads 23, effectively reduce the temperature of the LED lamp beads 23, reduce light decay, and further extend the service life of the lamp. A sealing gasket 26 is provided at the connection between the lens portion 22 and the heat sink 25. The sealing gasket 26 is made of silicone to prevent water and dust from entering the warning light 2. A lining frame 27 is provided near the lens portion 22 at the edge of the shell. The lining frame 27 is made of die-cast aluminum, which can not only dissipate the heat inside the lamp housing 21, but also enhance the strength of the lamp housing 21. The lining frame 27 presses the lens portion 22 against the sealing gasket 26, which plays a sealing role without affecting the relative position of the LED lamp beads 23 and the lens portion 22.

[0031] In this embodiment, the distance between the three projected warning lines 4 and the forklift body is 1.5-2 meters. A thermal pad 28 is provided between the radiator 25 and the wiring harness integrated board 24, and the wiring harness integrated board 24 and the thermal pad 28 are fixedly connected by bolts. The thermal pad 28 discharges the air between the wiring harness integrated board 24 and the radiator 25, so that the wiring harness integrated board 24 and the radiator 25 fit tightly, increasing the heat conduction effect of the radiator 25. The thermal pad 28 is made of graphite, which conducts the heat of the LED lamp bead 23 to the radiator 25, ensuring that the ambient temperature of the LED lamp bead 23 is lower than 50 degrees, prolonging the life of the LED lamp bead 23, reducing light decay, and ensuring the quality of the warning light 2. The wiring harness integrated board 24 is externally connected to the plug 5, and the plug 5 is connected to the battery of the forklift body 1.

[0032] In a preferred embodiment, sealant is filled between the wiring harness integrated board 24 and the heat sink 25 to fill the gap between the two, thereby increasing the connection relationship between the two and further improving the sealing between the two to prevent the intrusion of water or dust.

[0033] In a preferred embodiment, an external power supply is provided on the forklift body 1. When the forklift body 1 is not started, the external power supply can power the wiring harness integrated board 24, so that the LED lamp beads 23 emit light, and generate a straight projection warning line 4 under the reflection and refraction of the lens part 22, which is used to warn the surrounding personnel that the forklift body 1 is about to be used, and remind the surrounding personnel in the projection warning area 41 to leave the projection warning area 41.

[0034] Before using the forklift body 1, first control the warning light 2 to light up by plugging the plug 5 into an external power source, and adjust the angle of the warning light 2 according to the speed of the forklift body 1 or the surrounding environment, thereby adjusting the size of the projected warning area 41. After the adjustment is completed, start the forklift body 1 to operate.

[0035] This embodiment is only an illustration of the concept and implementation of the present invention, and does not limit it. Under the concept of the present invention, technical solutions that have not been substantially changed are still within the scope of protection.
