Description

Active arm forklift

【Technical field】

The utility model relates to a movable arm type forklift, which belongs to the field of hoisting machinery.

【Background technique】

Forklifts are an important tool used in the stacking and handling of warehouse goods. Existing goods handling forklifts can only lift goods up and then move them from one place to another. Its specific working parts are L-shaped mechanical arm forks that can be lifted at the front of the car body, which extend into the lower part of the goods to be transported, and carry the goods on the mechanical arm forks. Therefore, the function of existing forklifts is relatively single, and more multifunctional, convenient and flexible forklifts need to be developed urgently.

【Content of utility model】

The technical problem to be solved and the technical task proposed by the utility model are to overcome the defects of the prior art and provide a movable arm type forklift with multiple functions and flexible use. For this reason, the utility model adopts following technical scheme:

The movable arm type forklift includes a car body, a fixed gantry fixed on the car body and a drive system, and is characterized in that a set of lifting racks is provided on the fixed gantry, and a set of lifting racks are arranged parallel to the lifting racks. There is a gear box between the lifting and lowering sliding rods, the gears in the gear box cooperate with the lifting rack, and the front part of the gear box is provided with a pair of fork rotating boxes that are set on the fixed sliding rod of the fork. The fork rotating box described above is connected with a mechanical arm cargo fork. The provided fork rotation box can make the fork of the mechanical arm rotate around the horizontal center line, so that the fork of the mechanical arm can face each other to clamp the goods. It is beneficial to be used in a variety of handling and stacking environments. It can realize the stacking of ordinary fixed forks and the handling and stacking of heavy objects without pallets, reducing the trouble and cost of hiring additional workers for manual handling under special circumstances.

For the perfection and supplement of the above technical solutions, the following technical features can be added:

The mechanical arm fork includes the L-shaped mechanical arm fork rear section, the middle section of the mechanical arm fork and the front section of the mechanical arm fork connected with the fork rotating box, the L-shaped mechanical arm fork rear section, the mechanical arm The middle section of the fork is connected by a movable hydraulic cylinder of the fork, and the middle section of the fork of the mechanical arm and the front section of the fork of the mechanical arm are connected by a lever. The action of the three-stage mechanical arm cargo fork is more flexible than that of the L-shaped mechanical arm cargo fork in the prior art.

The upper surface of the front section of the mechanical arm fork is provided with anti-skid rubber. It is convenient for better lifting or clamping of goods.

The new manipulator fork of the utility model can more flexibly adapt to a variety of handling and stacking environments, realize the stacking of ordinary fixed forks and the handling and stacking of heavy objects without pallets, and reduce the need for special cases. The hassle and cost of hiring additional workers for manual handling.
