AI Technical Summary
When existing forklifts transport longer items, they are prone to incline and deflection of the items due to misalignment between the fork center line and the item center line, which affects transportation efficiency and may cause the items to fall.
A liftable pressure plate is provided above the fork, and the angle and position of the pressure plate are adjusted by the motor driving mechanism to maintain the stability of the item, ensuring that the pressure plate is pressed on the upper surface of the item, and the stability of the item on the fork is maintained by using the pressure of the pressure plate.
Even if the fork center line is not aligned with the item center line, the pressure of the pressure plate maintains the stability of the item on the fork, preventing the item from tilting and falling, and improving transportation safety and efficiency.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of forklifts, and more specifically relates to an anti-falling forklift. Background Art
[0002] Existing forklifts generally include a vehicle body, a mast is provided at the front end of the vehicle body, and a fork is provided on the mast. After the fork lifts an item, the mast will tilt at a certain angle towards the vehicle body direction, so that the side of the item can lean on the tilted mast, thus preventing higher items from falling during the forklift transportation process.
[0003] When transporting an item with a large length (exceeding the width of the fork), generally, the center line of the fork needs to be aligned with the center line of the item. Otherwise, the lifted item will tilt and deflect after being lifted, causing the item to fall to one side, affecting efficiency. The falling of the item will also affect the appearance and the internal structure and quality. Summary of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the utility model provides an anti-falling forklift. A pressing plate is arranged above the fork. When lifting an item, the pressing plate presses on the upper surface of the item, thereby maintaining the stability of the item.
[0005] To achieve the above object, the utility model provides the following technical solution: an anti-falling forklift, including a vehicle body and a mast, a fork is provided on the mast, pressing plates are arranged on both sides of the mast, the pressing plates are connected to the mast in a liftable manner, the pressing plates are located above the fork, and the distance between the two pressing plates is greater than the maximum width of the fork
[0006] Further, a support block is arranged between the pressing plate and the mast, the support block is connected to the mast in a liftable manner, and a first driving mechanism is arranged between the support block and the mast.
[0007] Further, the first driving mechanism includes a first motor, a first gear is arranged on the main shaft of the first motor, a rack corresponding to the first gear is arranged on the mast, the first gear meshes with the rack, and the first motor is fixedly connected to the support block.
[0008] Further, the pressing plate is rotatably connected to the support block, and a second driving mechanism is arranged between the pressing plate and the support block.
[0009] Further, the second driving mechanism includes a second motor, a second gear is arranged on the main shaft of the second motor, a third gear corresponding to the second gear is arranged on the rotating shaft of the pressing plate, and the second gear meshes with the third gear.
[0010] Further, a rubber pad is arranged on the pressing plate.
[0011] Further, a slide rail and slider mechanism is provided between the support block and the gantry.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: after the forklift forks pick up a relatively long item, the angle of the pressing plate is adjusted by the second motor, and then the first motor drives the support block to move downward until the pressing plate presses on the upper surface of the item. The stability of the item on the forklift forks can be maintained by the pressure of the pressing plate. Even if the center line of the forklift forks is not aligned with the center line of the item, as long as the deviation is not too large, the item can be kept stable on the forklift forks by the pressing plate, avoiding the item from tilting and falling.
