Description

Technical Field

[0001] The utility model relates to the technical field of overhead guards, in particular to an overhead guard for a forklift. Background Art

[0002] Forklifts are essential transport tools in the logistics industry, widely used in ports, docks, and various factory warehouses. They are high-lift, ride-on, and controlled engineering vehicles. They operate in complex environments, presenting safety hazards such as falling objects and cargo overturning, threatening the driver's life.

[0003] As a crucial component of forklifts, the overhead guard supports the entire cab and safeguards the driver's life. However, existing forklift guards are at best rigidly connected via fasteners, which offer poor impact resistance. When impacted by falling objects, the overhead guard structure can suffer devastating damage, compromising the driver's safety. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a forklift overhead guard, which overcomes the shortcomings of the existing technology and effectively solves the problem that the forklift protection in the existing technology is at most rigidly connected by fasteners, and its impact resistance is poor. When encountering the impact of falling objects from high altitude, the structure of the overhead guard may be devastated and affect the safety of the driver.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A forklift overhead guard includes a protective mechanism and a supporting mechanism. The protective mechanism includes a fixed plate, a sound insulation pad arranged on the top of the fixed plate, a buffer plate arranged on the top of the sound insulation pad, a protective frame connected to the top of the fixed plate, a connecting plate arranged on the top of the protective frame, protective plates equidistantly distributed around the connecting plate, and a top plate connected to the top of the connecting plate. The supporting mechanism includes a support rod, a support tube plugged into the top of the support rod, and a buffer spring arranged between the support rod and the support tube.

[0007] When an object falls on the top of the overhead guard, when the object contacts the top plate, the pyramid-shaped top plate will bounce the object to the side, and when the object contacts the protective plate, the end of the protective plate away from the connecting plate will elastically contract toward the protective frame through the elastic contraction of the telescopic spring, thereby buffering the falling force of the object. At this time, the tilted state of the protective plate will cause the object to slide downward, and the sound insulation pads and buffer plates will reduce the impact of the vibration sound on people under the overhead guard.

[0008] Preferably, a mounting groove is provided on the top of the fixing plate, and the sound insulation pad and the buffer plate are both arranged in the mounting groove.

[0009] The sound insulation pad and the buffer plate are installed and set through the installation groove.

[0010] Preferably, fixed blocks are fixed to the outer walls of the four sides of the connecting plate, and the fixed blocks are rotatably connected to the protective plate.

[0011] The connecting plate and the protective plate are connected and installed through a fixing block.

[0012] Preferably, the protective frame is a prismatic structure, and telescopic springs distributed at equal distances are connected between the four inclined surfaces of the protective frame and the four protective plates.

[0013] The elastic characteristics of the telescopic spring provide a buffer space between the protective frame and the protective plate.

[0014] Preferably, positioning holes are provided at the four corners of the top of the protective frame, and positioning rods are fixed at the four corners of the bottom of the top plate to form an interference fit with the positioning holes.

[0015] The top plate is connected to the top of the protective frame through a positioning rod.

[0016] Preferably, through holes are provided at the four corners of the top of the connecting plate, and the inner diameter of the through holes is matched with the inner diameter of the positioning rod.

[0017] The connecting plate is fastened between the top of the protective frame and the bottom of the top plate by plugging the positioning rod into the protective frame.

[0018] Preferably, a sliding block is fixed to the top of the support rod wall, and sliding grooves that form a sliding fit with the sliding block are provided on both sides of the annular inner wall of the support tube.

[0019] The support tube and the support rod are guided and slid by the sliding cooperation of the slider and the sliding groove.

[0020] The beneficial effects of the utility model are:

[0021] The protective mechanism is used to protect falling objects. When the object contacts the protective plate, the end of the protective plate away from the connecting plate is elastically contracted by the telescopic spring to move closer to the protective frame, thereby buffering the downward force of the object. At this time, the inclined state of the protective plate causes the object to slide downward. The sound insulation pad and buffer plate are provided to reduce the impact of the vibration sound on the people under the overhead guard. This effectively solves the problem that the forklift protection in the prior art is at most rigidly connected by fasteners, and its impact resistance is poor. When encountering the impact of falling objects from high altitude, the structure of the overhead guard may be devastated, affecting the safety of the driver. BRIEF DESCRIPTION OF THE DRAWINGS
