Abstract

The invention discloses a device for assembling and disassembling a tray, which comprises a plug board, plug board shelves, a telescopic supporting rod, a permanent seat, a U-shaped supporting arm and a fixed arm. In the invention, by taking the using direction as a reference, the left side and the right side of the plug board are respectively and fixedly provided with a plug board shelf, and the lower ends of the outer side walls of the two plug board shelves are hinged with the inner side walls of the opening ends of the U-shaped supporting arm; the end wall of the U-shaped supporting arm away from the opening end is fixed and positioned at one end of the fixed arm, and the upper sides of the two side walls of the U-shaped supporting arms are respectively and fixedly provided with a permanent seat of which the upper end can be hinged with the fixed end of the telescopic supporting rod; the movable end of the telescopic supporting rod is hinged with the upper ends of the plug board shelves; and one end of the plug board close to the fixed arm can be accommodated in the inner space of the U-shaped supporting arm. In the invention, the plug board is easy to control to turn over through a four-bar linkage mechanism, thus trays can be quickly and accurately assembled and disassembled, thereby the assembly and disassembly efficiency of the trays is improved.

Description

The device that is used for the pallet loading and unloading

Technical field

The present invention relates to a kind of handler, especially a kind of device for the pallet loading and unloading.

Background technology

The production of present industrial goods, transportation, storage and circulation etc. all realize by pallet, be placed on the pallet goods is stacked, a dead lift is generally all adopted in the loading and unloading of pallet at present, lifting or forklift operator, lifting namely drives hoist cable by the purlin car goods is transported to the pallet top, and then hoist cable taken off, goods is placed on the pallet, and it uses trouble, expends time in artificial, also need the purlin car, and need bigger space, use inconvenience, when adopting fork truck, goods need be placed on earlier on the pallet fork of fork truck, then, fork truck is transported to the pallet top with it, puts down goods again and withdraws from last, this needs the pallet fork lifting repeatedly of fork truck, troublesome poeration, consuming time, and pallet fork is easy to the goods band inclined to one side when withdrawing from, make the pendulum sign indicating number off normal phenomenon occur, pendulum sign indicating number off normal just causes the goods shelf-stability poor easily, and overturning easily takes place in transit, causes cargo damage.

Summary of the invention

In order to overcome above-mentioned defective, the invention provides a kind of device for the pallet loading and unloading, this device is loading or unloading pallet fast and accurately.

The present invention is in order to solve the technical scheme that its technical matters adopts: a kind of device for the pallet loading and unloading, comprise plate, flashboard rack, the retractable supports bar, permanent seat, U-shaped hold-down arm and fixed arm, to use direction to be benchmark, the plate left and right sides sets firmly a flashboard rack respectively, the lateral wall lower end of these two flashboard racks and the open end madial wall of U-shaped hold-down arm are articulated and connected, U-shaped hold-down arm is fixed positioned in fixed arm one end away from the end wall of open end, the two side upside of U-shaped hold-down arm is installed with a permanent seat respectively, the permanent seat upper end is hinged with the fixed end of retractable supports bar, the movable end of retractable supports bar and flashboard rack upper end are hinged, plate just can be placed in the U-shaped hold-down arm inner space near an end of fixed arm, flashboard rack like this, the retractable supports bar, permanent seat and U-shaped hold-down arm form a four-bar linkage, because the retractable supports bar is axially scalable, axial stretching by the retractable supports bar just drives flashboard rack around the articulated position rotation of itself and U-shaped hold-down arm like this, the rotation of flashboard rack has just driven the upset of whole plate, has namely realized the function of plate loading or unloading pallet.

As a further improvement on the present invention, the retractable supports bar is cylinder, and its movable end is the piston rod of cylinder, its fixed end is the cylinder body of cylinder, also can use hydraulic actuating cylinder or drive the cam rotation by motor, this type of all is the known structure of same domain technical personnel, no longer is described in detail herein.

As a further improvement on the present invention, the plate uper side surface is provided with ridge design, so just can increase friction, prevents that pallet from its surface slippage taking place even come off and cause damage.

As a further improvement on the present invention, flashboard rack becomes symmetrical distributions along U-shaped hold-down arm longitudinal center line.

As a further improvement on the present invention, described plate is the symmetrical distribution state along the two flashboard rack lines of centres, guarantees plate both sides stress balance like this.

The invention has the beneficial effects as follows: the present invention controls plate upset easily by a four-bar linkage, and so just loading or unloading pallet has fast and accurately improved the efficient of the loading and unloading of pallet.

The specific embodiment

Embodiment: a kind of device for the pallet loading and unloading, comprise plate 1, flashboard rack 2, retractable supports bar 3, permanent seat 4, U-shaped hold-down arm 5 and fixed arm 6, to use direction to be benchmark, plate 1 left and right sides sets firmly a flashboard rack 2 respectively, the lateral wall lower end of these two flashboard racks 2 and the open end madial wall of U-shaped hold-down arm 5 are articulated and connected, U-shaped hold-down arm 5 is fixed positioned in fixed arm 6 one ends away from the end wall of open end, the two side upside of U-shaped hold-down arm 5 is installed with a permanent seat 4 respectively, the fixed end of permanent seat 4 upper ends and retractable supports bar 3 is hinged, the movable end of retractable supports bar 3 and flashboard rack 2 upper ends are hinged, plate 1 just can be placed in U-shaped hold-down arm 5 inner spaces near an end of fixed arm 6, flashboard rack 2 like this, retractable supports bar 3, permanent seat 4 and U-shaped hold-down arm 5 form a four-bar linkage, because retractable supports bar 3 is axially scalable, axial stretching by retractable supports bar 3 just drives flashboard rack 2 around the articulated position rotation of itself and U-shaped hold-down arm 5 like this, the rotation of flashboard rack 2 has just driven the upset of whole plate 1, has namely realized the function of plate 1 loading or unloading pallet.

Described retractable supports bar 3 is cylinder, its movable end is the piston rod of cylinder, and its fixed end is the cylinder body of cylinder, also can use hydraulic actuating cylinder or drive the cam rotation by motor, this type of all is the known structure of same domain technical personnel, no longer is described in detail herein.

Described plate 1 uper side surface is provided with ridge design 11, so just can increase friction, prevents that pallet from its surface slippage taking place even come off and cause damage.

Described flashboard rack 2 becomes symmetrical distributions along U-shaped hold-down arm 5 longitudinal center lines.

Described plate 1 is the symmetrical distribution state along two flashboard racks, 2 lines of centres, can guarantee plate 1 both sides stress balance like this.
