Abstract

The utility model discloses a device used for loading and unloading a tray. The device comprises a plug board, plug board racks, a retractable support bar, fixed seats, a U-shaped supporting arm, and a fixed arm, wherein two plug board racks are fixedly arranged on the left and the right sides of the plug board based on the using direction, the lower ends of the outer side walls of the two plug board racks are hinged with the inner side wall of an opening end of the U-shaped supporting arm, and the end wall away from the opening end of the U-shaped supporting arm is fixedly positioned at one end of the fixed arm; a fixed seat is respectively arranged on the upper sides of two side walls of the U-shaped supporting arm; the upper end of the fixed seat is hinged with a fixed end of the retractable support bar, and a movable end of the retractable support bar is hinged with the upper end of the plug board rack; and the end where the plug board is near to the fixed arm is accommodated in the space inside the U-shaped supporting arm. The device can easily control the turning of the plug board through a four-bar mechanism, therefore, can quickly accurately load and unload the tray, and improve the loading and unloading efficiencies of the tray.

Description

The device that is used for the pallet loading and unloading

Technical field

The utility model relates to a kind of handler, especially a kind of device that is used for the pallet loading and unloading.

Background technology

Main equipment co-operate such as lifting, fork truck are generally all adopted in the loading and unloading of pallet at present, troublesome poeration, consuming time, and phenomenons such as off normal appear in pendulum sign indicating number easily.

The utility model content

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

The utility model is in order to solve the technical scheme that its technical matters adopts: a kind of device that is used for the pallet loading and unloading, comprise plate, flashboard rack, the retractable supports bar, permanent seat, U type 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 open end madial wall of the lateral wall lower end of these two flashboard racks and U type hold-down arm is articulated and connected, U type 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 type 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 type hold-down arm inner space near an end of fixed arm, flashboard rack like this, the retractable supports bar, permanent seat and U type 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 the articulated position rotation of flashboard rack around itself and U type hold-down arm like this, the rotation of flashboard rack has just driven the upset of whole plate, has promptly realized the function of plate loading or unloading pallet.

As further improvement of the utility model, the retractable supports bar is a cylinder, 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 further improvement of the utility model, 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 further improvement of the utility model, flashboard rack becomes symmetrical distributions along U type hold-down arm longitudinal center line.

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

The beneficial effects of the utility model are: the utility model is controlled 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 that is used for the pallet loading and unloading, comprise plate 1, flashboard rack 2, retractable supports bar 3, permanent seat 4, U type 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 open end madial wall of the lateral wall lower end of these two flashboard racks 2 and U type hold-down arm 5 is articulated and connected, U type 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 type 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 type 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 type 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 the articulated position rotation of flashboard rack 2 around itself and U type hold-down arm 5 like this, the rotation of flashboard rack 2 has just driven the upset of whole plate 1, has promptly realized the function of plate 1 loading or unloading pallet.

Described retractable supports bar 3 is a 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 type 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.
