Abstract
The utility model relates to a heavy-duty forklift truck. The heavy-duty forklift truck is simple in structure and high in safety coefficient, the production cost is reduced, and an oil cylinder can be prevented from explosion. The heavy-duty forklift truck comprises a truck body, a power system, a front fork device, and a front wheel set and a rear wheel set, which are arranged on the truck body. The front fork device comprises an oscillating oil cylinder, a bracket, a lifting frame and an L-shaped front fork plate arranged on the lifting frame. The bottom of the oscillating oil cylinder is hinged with the truck body. The bracket is arranged at the front end of the truck body in a way that the bottom of the bracket is hinged with the truck body, and is connected with a piston rod of the oscillating oil cylinder in a forward-backward oscillating way under the action of the oscillating oil cylinder. The lifting frame is arranged on the bracket in a lifting way under the action of a driving device. An oil drain valve for preventing the explosion of the oscillating oil cylinder due to the excessive lifting of the lifting frame is arranged above the lifting frame on the bracket, and is connected with the oscillating oil cylinder.
Description
Technical field
The utility model relates to a kind of heavy forklift.
Background technology
Fork truck refer to the member pallet cargo load and unload, the various wheeled carrying vehicle of stacking and short range transportation, weight transport operation.Being widely used in the each department of national economies such as station, harbour, airport, factory, warehouse, is the high-efficiency appliance of mechanized handling, stacking and short range transportation.Heavy forklift is that heavy forklift is a kind of of fork truck, is mainly used in the outdoor study of the industries such as the heavier harbour of goods, iron and steel.Existing heavy forklift generally includes vehicle body, power system, front fork unit and is located at forward and backward set of wheels on the vehicle body, described front fork unit comprises and waves oil cylinder, support, crane, is located at the L shaped front fork plate on the crane, described support is located at body structure in the mode that can unsteadily link to each other with the piston cylinder that waves oil cylinder, when fork picking thing, the piston rod that waves oil cylinder protracts, support is promoted downwards to make L shaped front fork front edge of board become a low-angle with ground, with convenient fork picking thing.During the heavy forklift cargo lifting, because the weight of goods is heavier, make that to wave the pressure that oil cylinder bears also very big, particularly when excessive height that article promote, even may make the oil cylinder detonation, thereby cause raising or the generation safety misadventure of productive costs.
Summary of the invention
Therefore, for above-mentioned problem, the utility model proposes a kind of simple in structure, safety factor is high, Decrease production cost, prevent the heavy forklift of oil cylinder detonation.
For achieving the above object, the utility model has adopted following technical scheme: a kind of heavy forklift, comprise vehicle body, power system, front fork unit and be located on the vehicle body before, the rear wheel group, described front fork unit comprises and waves oil cylinder, support, crane, be located at the L shaped front fork plate on the crane, the described oil cylinder bottom of waving is hinged and connected with vehicle body, described support is hinged and connected the ground mode with frame bottom and vehicle body and is located at body structure, described support can link to each other with the piston rod that waves oil cylinder under the effect of waving oil cylinder with rocking back and forth, described crane liftably is located on the support under the actuating device effect, the top that is positioned at crane on the described support is provided be used to preventing the too high spill valve that causes waving the oil cylinder detonation of crane lifting, described spill valve with wave oil cylinder and be connected.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: compare with existing heavy forklift, the top that is positioned at crane on the support of this heavy forklift is provided with spill valve, can effectively prevent from causing waving the oil cylinder detonation because the crane lifting is too high, make forklift operator safer, reduce simultaneously productive costs, improved production efficiency, reduced mechanical maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Now with the specific embodiment the utility model is further specified by reference to the accompanying drawings.
With reference to figure 1, a kind of heavy forklift of the present utility model, comprise vehicle body 1, power system, front fork unit and be located at front truck wheels 3 on the vehicle body, rear wheel group 4, described front fork unit comprises and waves oil cylinder 21, support 22, crane 23, be located at the L shaped front fork plate 24 on the crane 23, describedly wave oil cylinder 21 bottoms and vehicle body 1 is hinged and connected, described support 22 is hinged and connected the ground mode with support 22 bottoms and vehicle body 1 and is located at vehicle body 1 front end, described support 22 can link to each other with the piston rod that waves oil cylinder 21 under the effect of waving oil cylinder 21 with rocking back and forth, described crane 23 liftably is being located under the actuating device effect on the support 22, the top that is positioned at crane 23 on the described support 22 is provided be used to preventing the too high spill valve 5 that causes waving oil cylinder 21 detonations of crane 23 liftings, described spill valve 5 with wave oil cylinder 21 and be connected.
Compare with existing heavy forklift, the top that is positioned at crane on the support of this heavy forklift is provided with spill valve, can effectively prevent from causing waving the oil cylinder detonation because the crane lifting is too high, make forklift operator safer, reduced simultaneously productive costs, improve production efficiency, reduced mechanical maintenance.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
