When unloading, the lifting mechanism and the vehicle plate 1 are pulled to do relative motion in the horizontal direction, the lifting mechanism is adjusted, and after the chassis 6 of the lifting mechanism is contacted with the ground, the vehicle plate 1 is pulled out, and the lifting mechanism is retracted. The loading and unloading process does not need to be carried again, thereby achieving the purpose of reducing the manpower and time consumption.

In some embodiments of the present utility model, the deck is a U-shaped fork as shown in FIG. 3. The spacing between the two tines 110 of the U-shaped fork is adjustable. A telescopic rod 12 is arranged between the two tines 110. When the truck is not required to load goods, the distance between the two tines 110 can be adjusted by the truck so as to reduce the distance between the two tines 110. After the distance between the two tines 110 is reduced, the occupied space of the forklift truck is reduced. And the distance between the two tines 110 is adjustable, so that the logistics tray can be suitable for different types of logistics trays.

In some embodiments of the present utility model, the U-shaped fork 11 is open forward as shown in FIG. 4. The pallet 1 is a U-shaped fork 11, the U-shaped fork 11 comprising two forward facing tines. When loading cargoes on the forklift truck, the U-shaped fork 11 can be inserted into the logistics tray, so that cargoes can be pushed away directly. And the cargoes do not need to be carried on the forklift, so that the manpower and time are saved.

In some embodiments of the present utility model, the thickness of the opening of the U-shaped fork 11 is thinner than the thickness of the connection of the U-shaped fork 11. When the cargoes need to be shipped, the U-shaped fork 11 at the opening is thinner, so that the U-shaped fork 11 can enter the lower part of the logistics tray.

In some embodiments of the utility model, as shown in fig. 4, the lifting mechanism includes two sets of scissor mechanisms. The two sets of scissors mechanisms are respectively arranged below the left fork tooth and the right fork tooth of the U-shaped fork 11 and are arranged on the upper side of the chassis 6. The two groups of shearing fork mechanisms are symmetrically arranged, and the shearing fork mechanisms operate smoothly when in work bearing, so that the goods on the truck board 1 cannot shake severely. The folded vehicle has small occupied space and can be arranged below the vehicle plate 1.

Further, in some embodiments of the utility model, the scissor mechanism comprises two scissor arms 4. The two scissor arms 4 are connected in a crossed and rotating way. When the vehicle plate 1 needs to be lifted, the two scissor arms 4 rotate, and the included angles between the two scissor arms 4 and the horizontal direction become larger, so that the vehicle plate 1 is lifted. When the vehicle plate 1 needs to descend, the two scissor arms 4 rotate, and the included angles between the two scissor arms 4 and the horizontal direction are reduced, so that the vehicle plate 1 descends. The two shearing fork arms 4 are in cross rotation connection, simple in structure and stable in operation.

In other embodiments of the utility model, the scissor mechanism may also be a double-scissor, i.e. the scissor mechanism comprises four scissor arms 4, which may enable a higher lift distance of the assembly of the deck 1.

In some embodiments of the utility model, the lift mechanism further comprises a telescopic device that drives the link scissor mechanism to urge the deck 1 relatively far away from the chassis 6 indirectly with extension of the telescopic device.

Further, as shown in fig. 1, the telescopic device is a first hydraulic cylinder 5.

When the first hydraulic cylinder works, the two first piston rods extend out, so that the two scissor arms 4 rotate and the included angle between the two scissor arms and the horizontal direction is increased, and the vehicle plate 1 is lifted. The first hydraulic cylinder 5 is arranged on the shearing fork arm 4, so that space is saved.

In some alternative embodiments of the utility model, the lift mechanism further comprises a telescoping device connected between the rear side of the chassis 6 and the rear side of the deck 1 to urge the deck 1 relatively far away from the chassis 6 directly with the telescoping device's extension.

Further, as shown in fig. 7, the telescopic device is a second hydraulic cylinder 50, and the second hydraulic cylinder 50 is disposed on one side of the truck-mounted forklift, which is close to the armrest. The second hydraulic cylinder 50 comprises a second piston rod, and the upper end of the second piston rod is fixedly connected with the vehicle plate 1. When the second hydraulic cylinder is operated, the second hydraulic cylinder 50 lifts the second piston rod to lift the deck 1. Because the second hydraulic cylinder 50 is arranged on one side of the truck-mounted forklift, which is close to the handrail, when the truck-mounted forklift is in a retracted state, the second hydraulic cylinder 50 does not interfere with the fork teeth 110, so that the fork teeth 110 can be inserted below the logistics tray. And the second hydraulic cylinder 50 directly urges the deck 1 relatively far away from the chassis 6 with extension of the second piston rod, increasing the load capacity of the truck with respect to indirect drive.

In some alternative embodiments of the utility model, a telescopic device is connected between the rear side of the chassis 6 and the rear side of the deck 1, and the telescopic device drives the connecting scissor mechanism to urge the deck 1 relatively far away from the chassis 6, either indirectly or directly as the telescopic device is extended.

In other embodiments of the utility model the scissor structure may also be moved by a winch and a wire rope attached to the winch, which wire rope is looped over the upper end of the uppermost scissor arm 4. The winch is turned to retract the wire rope so that the scissor arms 4 are opened or contracted. When the wire rope is loosened, the upper ends of the scissor arms 4 are opened, and the distance between the sweep plate 1 and the chassis 6 is reduced. When the steel wire rope is tightened, the upper ends of the scissor arms 4 are folded, and the distance between the vehicle plate 1 and the chassis 6 is increased.

In some embodiments of the present utility model, as shown in fig. 2, the truck-mounted forklift further includes a sliding rail 7, where the sliding rail 7 is disposed on the deck 1 along the front-rear direction, and the upper end of the lifting mechanism is slidably connected to the deck 1 through the sliding rail 7. The upper ends of the sweep 1 and the lifting mechanism are connected through the sliding rail 7, so that the sliding rail 7 plays a supporting role on the sweep 1 when the sweep 1 and the lifting mechanism do relative motion in the front-back direction, and meanwhile, the sliding friction between the sweep 1 and the lifting mechanism of the sliding rail 7 is reduced.

Further, in some embodiments of the present utility model, as shown in fig. 2, there are two sliding rails, and the two sliding rails are disposed at left and right sides of the vehicle panel 1 at intervals. The two slide rails are multi-section telescopic slide rails. The arrangement of two slide rails is used for improving the stability of sliding connection. The multi-section telescopic sliding rail is used for prolonging the sliding range of the vehicle plate assembly along the front-back direction.

Further, in some embodiments of the present utility model, the truck-mounted forklift further comprises a stop device, which is disposed on the slide rail 7. The stop device is configured to, when opened, stop the vehicle panel assembly from sliding relative to the lift mechanism. The stop device can stop the relative sliding of the vehicle plate component and the lifting mechanism. The stop means may be a latch. When the relative sliding of the vehicle stopping plate component and the lifting mechanism is required, the bolt can be inserted into the sliding rail 7, so that the sliding rail 7 cannot slide, and the relative sliding of the vehicle stopping plate component and the lifting mechanism is further stopped.

In some embodiments of the utility model, the chassis 6 is provided with running gear.

Preferably, in some embodiments of the utility model, the running gear is a wheel 20, as shown in fig. 7. When the lifting mechanism is raised, the cart can still be moved with the wheels 20 on the chassis 6.
