Description

Fork truck crane Technical Field The utility model relates to the technical field of forklifts, in particular to a forklift lifting frame. Background The forklift is an industrial carrying vehicle, and is various wheeled carrying vehicles for loading and unloading, stacking and short-distance transportation of finished pallet cargoes, is commonly used for transporting large articles in storage, is commonly driven by a fuel engine or a battery, belongs to special motor vehicles in a field (factory), and is widely applied to scenes such as warehouses, ports and factories. Patent No. 20232005401. X discloses a fork truck frame lifting device, the device fork truck removes the portal to suitable position to make fork truck connect fixed frame operation more convenient. However, when the existing forklift frame lifting device is used, the fork frame is connected with a forklift by utilizing the structures such as the two groups of sliding blocks and the sliding rails, the space between the structures such as the two groups of sliding blocks and the sliding rails is fixed, the installation efficiency of the fork frame is affected to a certain extent, and meanwhile, the fork frame cannot adjust the specification of the fork frame after the use is finished, so that the safety performance is low, and the forklift lifting frame is arranged. Disclosure of utility model Aiming at the problems in the background technology, the utility model provides a forklift lifting frame. The technical scheme adopted by the utility model for solving the technical problems is that the forklift truck lifting frame comprises a lifting frame, a fork frame is connected to the outer portion of the lifting frame in a sliding manner, a transmission assembly is arranged inside the fork frame, a front fork which is in contact with goods is inserted into one side of the fork frame, an adjusting assembly which drives the front fork to move is arranged on the inner side of the fork frame, a fixing frame which is connected with a forklift truck is connected to the outer portion of the lifting frame in a bolt manner, a limiting block A and a limiting block B are connected to the outer portion of the fixing frame in a sliding manner, and a driving assembly is arranged inside the fixing frame.
