Description

Technical Field

[0001] This utility model relates to the field of forklift accessories technology, specifically to an extension loading and unloading device for a forklift mast. Background Technology

[0002] Pallet stackers are a type of industrial handling vehicle, mainly used for loading, unloading, stacking, and short-distance transportation of palletized goods. A pallet stacker is a small vehicle equipped with a power transmission and lifting device, capable of loading, unloading, handling, and stacking pallets and palletized goods. It belongs to the battery-powered stacking vehicle category. Pallet stackers are suitable for operations in narrow aisles and confined spaces, making them ideal tools for the warehousing and logistics industry. Many domestic and international manufacturers produce pallet stackers, and their functions are largely similar. However, due to specific operational characteristics in warehousing and logistics, subtle differences in the functions and structural design of pallet stackers can affect their operational efficiency and safety.

[0003] Forklifts are a general term for industrial handling vehicles used for loading, unloading, stacking, and short-distance transportation of palletized goods. Stacker trucks are a type of forklift. Traditional forklifts with high masts cannot operate properly in low-ceilinged spaces. While low-mast forklifts can enter these spaces, their standard loading and unloading devices have insufficient extension capacity, making it difficult to reach goods that are far away or located on high shelves. This results in frequent adjustments to the forklift position during goods handling. In addition, the fork width cannot be adjusted, reducing operational efficiency. Therefore, there is an urgent need for a low-mast forklift extension loading and unloading device to overcome these shortcomings. Summary of the Invention

[0004] The purpose of this utility model is to provide an extension loading and unloading device for a forklift mast, which has the advantages of convenient adjustment and easy loading, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an extension loading and unloading device for a forklift mast, comprising a moving mechanism, a lifting mechanism, a heightening component, and a telescopic moving component. The lifting mechanism is fixedly installed on the back of the moving mechanism, the heightening component is disposed on the back of the lifting mechanism, and the telescopic moving component is disposed on the back of the heightening component. The heightening component includes a moving rod, a first motor, a first slide groove, a first threaded rod, and a first slider. The telescopic moving component includes a baffle frame, a fixed rod, a moving block, a support base, an electric push rod, a second slide groove, a second slider, a third slide groove, a third slider, a second motor, and a second threaded rod.

[0006] Furthermore, a movable rod is fixedly installed at the center of the back of the lifting mechanism, a first motor is fixedly installed at the top of the movable rod, a first sliding groove is opened inside the movable rod, and a first slider is slidably connected inside the first sliding groove.

[0007] Furthermore, the first slider is internally connected to a first threaded rod via a threaded connection, the output shaft of the first motor passes through the inner cavity of the first slide groove and is fixedly connected to the top of the first threaded rod, a baffle frame is fixedly installed on the back of the first slider, and a fixing rod is fixedly installed on the back of the baffle frame.

[0008] Furthermore, a second motor is fixedly installed on the left side of the fixing rod, and a third sliding groove is opened inside the fixing rod, with two third sliders slidably connected inside the third sliding groove.

[0009] Furthermore, the interior of the third slider is rotatably connected to a second threaded rod via a thread, the output shaft of the second motor passes through the inner cavity of the third slide groove and is fixedly connected to the left side of the second threaded rod, and a movable block is fixedly installed on the back of the third slider.

[0010] Furthermore, an electric push rod is fixedly installed on the side of the movable block that is relatively far away from it, a base is provided on the surface of the movable block, and a second sliding groove is provided on the top and bottom of the movable block.

[0011] Furthermore, a second slider is slidably connected inside the second groove, with the side of the second slider that is relatively far away from the inner cavity of the support base being fixedly connected, and the side of the electric push rod that is relatively close to the outer side of the support base being fixedly connected.

[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0013] This invention facilitates the transfer of the entire device by incorporating a moving mechanism, and moves the lifting and telescopic moving components by incorporating a lifting mechanism. The lifting component increases the lifting distance, while the telescopic moving component primarily lifts loads of varying widths. To further lift the load, the first motor is activated, driving the first threaded rod to rotate, which in turn causes the first slider to lift the fixed rod, baffle frame, and load further. To adjust the fit according to the load width, the second motor is activated, driving the second threaded rod to rotate, which in turn causes the third slider to move the moving block to the designated position. Then, the electric push rod is activated, moving the support base backward to adapt to the load area. This design offers advantages such as convenient adjustment and easy loading, solving the problems of traditional forklifts with high masts being unable to operate normally in low-ceilinged spaces, and low-mast forklifts, which, while able to enter, have insufficient extension capacity of standard loading and unloading devices, making it difficult to reach goods that are far away or located on high shelves. This results in frequent forklift position adjustments during cargo handling, and the inability to adjust the fork width reduces operational efficiency. Attached Figure Description
