Front fork and portal double-folding device capable of moving forwards and backwards

Abstract

The invention discloses a front fork and portal double-folding device capable of moving forwards and backwards. The front fork and portal double-folding device capable of moving forwards and backwards is characterized in that the device comprises a pallet fork, an inner portal, an outer portal and a guide rail forklift frame; the pallet fork comprises a front fork and a pallet fork carrier; the front fork is rotatably connected with the pallet fork carrier; the inner portal and the outer portal are slidably connected in a matched mode, the inner portal and the outer portal are vertically arranged, and the inner portal and the outer portal can rotate around the lower portion of the outer portal; the guide rail forklift frame is horizontally arranged, and the outer portal and the guide rail forklift frame are slidably connected in a matched mode; and the pallet fork carrier is arranged on the inner portal, and the pallet fork carrier is slidably connected with the inner portal in a matched mode through a lifting assembly. According to a forklift provided with the device, forklift transportation is slightly limited, the weight of the whole forklift is low, and the using cost and transportation cost are low.

Description

technical field [0001] The invention relates to the field of transport tools, and relates to components of a forklift, in particular to a double-folding front and rear movable device of a front fork and a mast. Background technique [0002] Forklifts are industrial transport vehicles, which refer to various wheeled transport vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. They are often used for the transportation of large objects in storage. [0003] At present, the forklift mast system on the market is generally fixed in front of the forklift, and can only rotate at a very small angle along its rotating shaft or fixed shaft. When the angle between the forklift driving road and the object placement plane is greater than the swing angle of the oil cylinder, it will not be able to forklift; The entire gantry system cannot move backwards, and the center of gravity of the whole machine moves forward, and the balance of the who...

Problems solved by technology

[0003] At present, the forklift mast system on the market is generally fixed in front of the forklift, and can only rotate at a very small angle along its rotating shaft or fixed shaft. When the angle between the forklift driving road and the object placement plane is greater than the swing angle of the oil cylinder, it will not be able to forklift; The entire gantry system cannot move backwards, and the center of gravity of the whole machine moves forward, and the balance of the whole machine during forklifting is achieved by adding counterweights, which undoubtedly increases the weight of the whole machine and additionally increases the power of the engine; since the gantry system cannot Putting it down, the transportation of the forklift itself will use a special transportation vehicle, and the quantity of one-time transportation is small, and the transportation cost is high
