Description

Technical Field

[0001] The utility model relates to the technical field of electric forklifts, in particular to an electric forklift with a four-wheel synchronous driving mechanism. Background Art

[0002] Electric forklifts are forklifts that operate on electricity, most of which are powered by batteries. Four-wheel drive electric forklifts utilize an electric drive system and four-wheel drive technology. Compared to traditional internal combustion forklifts, electric forklifts are gaining popularity among businesses due to their environmental friendliness, low noise levels, and lower maintenance costs.

[0003] Four-wheel drive electric forklifts are commonly used in warehousing, logistics, manufacturing, construction sites, and other locations requiring heavy load handling. However, existing electric forklifts with four-wheel synchronous drive mechanisms have a disadvantage: they lack a protective structure. When lifting palletized cargo using forks, the cargo can fall or collapse due to tilting or shaking. To address this issue, we propose an electric forklift with a four-wheel synchronous drive mechanism. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the deficiencies in the prior art, the utility model provides an electric forklift with a four-wheel synchronous drive mechanism, which solves the problems raised in the background art.

[0006] (2) Technical solution

[0007] The utility model provides the following technical solutions: an electric forklift with a four-wheel synchronous drive mechanism, comprising a four-wheel drive electric forklift body, a structural plate, a connecting plate and a protective assembly;

[0008] The structural plate is fixed to the top of the door frame of the four-wheel drive electric forklift body by bolts, and reduction motors are installed at both ends of the top of the structural plate through mounting brackets. Structural grooves are opened at both ends of one side of the structural plate, and a screw rod is rotatably connected inside the structural groove through a bearing. The connecting plate is sleeved on one end of the structural groove, and the end of the connecting plate away from the structural plate is fixed with a layer plate by bolts, and an insulating plate is fixed to the top of the layer plate by bolts. The protective component is equidistantly arranged inside the insulating plate, and the protective component includes reserved grooves equidistantly opened inside the insulating plate, and an iron sleeve is fixed inside the reserved groove, and an electromagnetic coil is sleeved on the outside of the iron sleeve located inside the reserved groove. A compression spring is fixed to the top of the iron sleeve by bolts, and a cargo barrier rod is sleeved on the bottom end of the iron sleeve.

[0009] Furthermore, the output shaft of the reduction motor located inside the structural groove is provided with a second bevel gear through a flat key fixing sleeve, and a first bevel gear is fixedly provided at one end of the outer side of the screw rod, and the first bevel gear and the second bevel gear are meshed.

[0010] Furthermore, a thread groove is provided inside the connecting plate, one end of the screw rod is located inside the thread groove, and the connecting plate is fixed with limit blocks on both sides inside the structural groove by bolts.

[0011] Furthermore, the top end of the cargo blocking rod located inside the iron casing is fixed to a limit plate by bolts, the bottom end of the compression spring is fixed to the top of the limit plate by bolts, and the cargo blocking rod passes through the layer plate.

[0012] Furthermore, mounting plates are welded on both sides of the structural plate, and through grooves are uniformly spaced through the interior of the structural plate.

[0013] Furthermore, the insulating board is made of glass fiber material.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When the four-wheel drive electric forklift is driven to pick up the goods stacked on the pallet, the reduction motor is turned on to drive the screw to rotate through the second bevel gear and the first bevel gear. The screw rotates the thread groove to push the connecting plate and the layer plate at one end to move, and move the layer plate to the side of the goods away from the four-wheel drive electric forklift body;

[0016] Under normal circumstances, the electromagnetic coil is energized to generate magnetism in the iron casing, thereby adsorbing the cargo blocking rod into the iron casing so that the cargo blocking rod does not affect the movement of the connecting plate on the cargo. When the shelf moves to the side where the cargo is away from the four-wheel drive electric forklift body, the power supply to the electromagnetic coil is disconnected, and the compression spring pushes the cargo blocking rod downward through the limit plate. Multiple cargo blocking rods block the cargo on the pallet;

[0017] This electric forklift with a four-wheel synchronous drive mechanism drives the connecting plate and the layer plate to move through the reduction motor, the lead screw and the threaded groove, so that the cargo stopper is moved to the side where the cargo is away from the four-wheel drive electric forklift body. The compression spring pushes the cargo stopper to extend through the limit plate, blocking the stacked cargo so that it will not fall off or collapse due to skewness or shaking.
