Description

Fork truck for dual-purpose

Technical Field

The invention relates to the technical field of cargo transportation loading and unloading vehicles, in particular to a dual-function forklift.

Background

With the increasing development of socio-economy, the logistics and labor cost gradually rises, so the pipeline transportation industry is rising rapidly. The pipeline is heavy, large in size, long in length and the like, so that logistics carrying and installation are very difficult. At present, the carrying mode on the market is mostly the hoist and mount mode, and is inefficient, and the security is low, because the stability of hoist and mount is low to cause the collision easily and cause loss of property. Present building site uses standard pipe fitting in a large number, the rapid development of pipe fitting lease business has been promoted, however when transporting the steel pipe, because the steel pipe surface is too slick and sly to lead to the steel pipe easily turning on one's side or the landing in the transportation, and can lead to the steel pipe to have the risk of empting during vertical transportation steel pipe, the steel pipe is too high and inconvenient transportation simultaneously, the operation mode intensity of labour who adopts artifical or handcart transport is big, the operating efficiency is low, waste time and energy, there is the potential safety hazard still, although develop the fork truck that is used for the steel pipe transportation for this reason, like chinese patent literature: the gravity type steel pipe clamp forklift is CN201510119670.X, the steel pipe clamping mechanism and the steel pipe clamping and forking method thereof, and the gravity type steel pipe clamp forklift is CN201520154925.1 and the steel pipe clamping mechanism thereof, but the gravity type steel pipe clamp forklift can only be used for transporting steel pipes, and other goods such as loading and unloading boxes of the forklift cannot be transported and are inconvenient to use, so that the application range is limited.

Disclosure of Invention

Therefore, aiming at the problems, the invention provides the dual-function forklift which has the advantages of reasonable and stable structure, stable pipeline carrying, safe and convenient use and high carrying efficiency, can be used as a normal forklift and can clamp and transport steel pipes.

In order to solve the technical problem, the invention adopts the following scheme: the utility model provides a fork truck for dual function, includes the fork truck body, be connected with two L type forks on the anterior crane and the crane that are equipped with of fork truck body, still include support frame and two sets of centre gripping unit, the support frame is located the crane of fork truck body, and two sets of centre gripping units locate respectively on the support frame both sides and two sets of centre gripping units are located two L type forks top respectively, and two sets of centre gripping units all include first actuating mechanism, second actuating mechanism and arm lock, and two L type forks tops are violently located respectively to the arm lock of two sets of centre gripping units, the vertical output of locating support frame upper portion and first actuating mechanism of first actuating mechanism articulates with arm lock one end above-mentioned mutually, first actuating mechanism output oscilaltion drives arm lock one end oscilaltion, second actuating mechanism articulates above locating support frame middle part and second actuating mechanism's output and the other end of keeping away from first actuating mechanism with the arm lock and articulates mutually, second actuating mechanism output drives the arm lock other end oscilaltion of keeping away from first actuating mechanism.

Furthermore, the two groups of clamping units respectively comprise sliding seats, the sliding seats of the two groups of clamping units are respectively arranged on two sides of the supporting frame in a vertically sliding manner, and one end part of the clamping arm, which is hinged with the output end of the first driving mechanism, is hinged with the sliding seats.

Furthermore, one end part of the clamping arm, which is hinged with the output end of the first driving mechanism, is hinged with the lower part of the sliding seat, and the second driving mechanism is hinged with one side of the upper part of the sliding seat.

Furthermore, the first driving mechanism is lifted to drive the clamping arm to ascend, the output end of the second driving mechanism is jacked to enable the included angle formed by the hinged end of the clamping arm and the sliding seat and the horizontal plane to be 5-15 degrees, the first driving mechanism is pressed downwards to drive the clamping arm to descend, the output end of the second driving mechanism retracts to drive the clamping arm to ascend, and the included angle formed by the hinged other end of the clamping arm and the second driving mechanism and the horizontal plane to be 85-90 degrees.

Furthermore, the lower surface of the clamping arm is provided with a rubber clamping plate.

Furthermore, the first driving mechanism and the second driving mechanism are both cylinders or oil cylinders.

Furthermore, the upper surfaces of the transverse forks of the two L-shaped forks are smooth planes.

Furthermore, the support frame is a lifting frame of the forklift body.

By adopting the technical scheme, the invention has the beneficial effects that: the two groups of clamping units are installed on the lifting frame at the front end of the existing forklift body and are respectively matched with the two L-shaped forks, when a pipeline is clamped, the first driving mechanism presses down to drive one end of each clamping arm to descend, the output end of the second driving mechanism retracts to drive the free end of each clamping arm to lift up, the L-shaped forks are inserted into the bottom of the pipeline, the first driving mechanism is lifted to drive the clamping arms to ascend, the output end of the second driving mechanism is ejected to enable the free ends of the clamping arms to press down to be matched with the L-shaped forks to stably clamp the pipeline, when the pipeline is not clamped, the first driving mechanism presses down to drive one end of each clamping arm to descend to the bottom, and the output ends of the second driving mechanisms retract to drive the free ends of the clamping arms to lift up to enable the free ends of the clamping arms to retract to the upper portion of the supporting frame, so that the normal fork taking function of the forklift can be recovered, the influence of the two groups of clamping units of the forklift is avoided, the performance of the forklift is more flexible and diversified, the forklift is reasonable and stable in structure, stable and convenient to carry the pipeline, and safe and high in use, and can be used as a normal application and can clamp a transportation steel pipe. Through further setting, the setting of slide makes the structure between centre gripping unit and the support frame more firm and make the arm lock remove more smoothly promptly, it increases the frictional force of arm lock and pipeline contact to make arm lock and L type fork cooperation firmly grasp the pipeline more to be equipped with the rubber slab on the arm lock, prevent the pipeline landing, the smooth plane of the horizontal fork of two L type forks makes the power convenient and fast's that L type fork passes through the fork truck body insert and can not damage the pipeline from the pipeline bottom, the overall structure can further be optimized as an organic whole to the lift frame of the crane of support frame and fork truck body, the cost is reduced, and the wide popularization and application can be realized.
