Description

Storage forklift

Technical Field

The invention relates to the technical field of warehousing, in particular to a warehousing forklift.

Background

Fork trucks are industrial handling vehicles, and refer to various wheeled handling vehicles that perform handling, stacking, and short-distance transport operations on piece pallet goods. Along with the development of the social logistics industry, the corresponding logistics forklift is more and more widely used, and in a plurality of storage warehouses of a logistics company, workers are often seen to start the logistics forklift to carry goods.

The fork truck passageway that traditional fork truck need occupy is wider, because traditional fork truck needs turning radius, still must reserve great space at fork truck passageway access & exit and supply traditional fork truck to turn.

Disclosure of Invention

In order to solve the technical problems, the invention provides a storage forklift, which needs to occupy a narrow forklift passageway without turning radius and can greatly improve the density of goods shelves in a storage area.

In order to solve the problems, the invention adopts the following technical scheme:

the storage forklift comprises a movable chassis and a fork assembly, wherein the movable chassis is U-shaped and comprises walking mechanisms symmetrically arranged from left to right and a connecting plate for connecting the rear ends of the two walking mechanisms, the fork assembly is arranged between the two walking mechanisms, a translation mechanism for driving the fork assembly to translate back and forth is arranged on the movable chassis, the fork assembly comprises a frame body, a fork and a lifting mechanism, the lifting mechanism is arranged on the frame body, and the fork is connected with the lifting end of the lifting mechanism.

In this scheme, remove the chassis and be used for driving storage fork truck and remove. When putting goods, it drives storage fork truck to remove before the position of putting goods of corresponding goods shelves to remove the chassis, elevating system drives the fork and rises to corresponding position height of putting goods, translation mechanism drives the fork subassembly and moves forward, make the goods on the fork move to corresponding position top of putting goods, then, elevating system drives the fork and descends one section distance, make the goods put to corresponding position of putting goods, and finally, translation mechanism drives the fork subassembly and moves backward, the fork shifts out the position of putting goods, accomplish the goods of putting. When getting goods, it drives storage fork truck to remove to the position of putting goods of corresponding goods shelves before to remove the chassis, elevating system drives the fork and rises to corresponding position of putting goods height, translation mechanism drives the fork subassembly and moves forward, make the fork stretch into the goods below on the corresponding position of putting goods, then, elevating system drives the fork and rises a section distance, upwards hold up the goods and put the position contactless, finally, translation mechanism drives the fork subassembly and moves backward, the fork holds in the palm the goods and shifts out the position of putting goods, accomplish and get goods.

The storage fork truck of this scheme sets up the fork subassembly in the removal chassis of U font, when getting put goods, but the independent back-and-forth movement of fork subassembly is got and is put goods, only needs constrictive fork truck passageway just can normally work, does not like traditional storage fork truck, sets up the fork in the automobile body front side, needs whole automobile body back-and-forth movement to get and puts goods, the fork truck passageway broad that needs to occupy.

Preferably, the walking mechanism comprises a base, a walking assembly is arranged at the bottom of the base, a rotating motor used for driving the walking assembly to rotate is arranged on the base, and the walking assembly comprises a driving wheel and a walking motor used for driving the driving wheel to rotate.

The direction of the walking assembly can be adjusted by the rotating motor, so that the walking assembly can move along any direction. Horizontal migration about storage fork truck in the fork truck passageway, after storage fork truck left the fork truck passageway, the rotating electrical machines was adjusted the running assembly and is rotated 90 degrees, and storage fork truck just can the back-and-forth movement like this, so the storage fork truck of this scheme need not turn radius, need not occupy very big space at fork truck passageway access & exit, and the width in fork truck passageway also correspondingly need not very wide simultaneously.

As preferred, translation mechanism sets up the translation subassembly on two running gear including the symmetry, the translation subassembly moves towards the setting around running gear, the translation subassembly includes drive assembly, support, sets up guide rail on the support, sets up and just can follow the gliding slider of guide rail on the guide rail, slider and support body fixed connection, drive assembly establishes the chain on two sprockets, sets up the chain connecting block on the chain including setting up sprocket, the cover at both ends around running gear, the chain moves towards unanimously with the guide rail trend, chain connecting block and support body fixed connection, the sprocket rotates with running gear to be connected, translation mechanism is still including being used for driving sprocket pivoted drive module.

The support is arranged along the front and back direction of the walking mechanism, and the direction of the guide rail is consistent with that of the support. The driving module drives the chain wheel to rotate, the chain wheel rotates to drive the chain to rotate, and the chain rotates to drive the frame body to move back and forth through the chain connecting block, so that the front and back translation functions of the translation mechanism are realized.

Preferably, the support comprises a pin hole plate and a plurality of pin shafts arranged on the upper surface of the travelling mechanism, pin holes are formed in the positions, corresponding to the pin shafts, of the pin hole plate, the pin shafts are inserted into the corresponding pin holes, the diameters of the pin holes are larger than those of the pin shafts, and the guide rails are arranged on the pin hole plate.

The diameter of the pin hole is slightly larger than that of the pin shaft, so that when the storage forklift moves on uneven ground, the walking mechanism and the pallet fork assembly are flexible, and the shock absorption effect is achieved.

Preferably, the driving module comprises a driving motor and a transmission shaft, two ends of the transmission shaft are respectively and coaxially connected with the chain wheels at the rear ends of the two walking mechanisms, and the driving motor is used for driving the transmission shaft to rotate.

Preferably, the fork includes the riser of vertical setting and sets up two first diaphragms in the riser bottom, the riser is connected with elevating system's lift end, first diaphragm moves towards the level setting around along, the riser front side is equipped with first camera. The first camera is used for positioning the height and the position of the goods, and the first transverse plate is used for carrying the goods.

Preferably, the bottom of the frame body is provided with two second transverse plates which are horizontally arranged along the front-back direction, the two second transverse plates are respectively positioned under the two first transverse plates, and the bottom of each second transverse plate is provided with a first universal wheel. The setting up of second diaphragm makes the support body more stable for the fork can carry heavier goods, avoids the fork to topple over when the handling is heavier goods in the unstability of storage fork truck focus.

Preferably, a first guide wheel is arranged on the inner side of the travelling mechanism, and the first guide wheel abuts against the adjacent second transverse plate. The first guide wheel is abutted to the second transverse plate on one corresponding side, so that the guide effect on the front and back translation of the second transverse plate is achieved, and the interaction force of the guide rail and the sliding block is reduced.
