Description

Box pallet fork car functions expanding arm

Technical field

The utility model relates to fork truck.

Background technology

Fork truck is widely used in worker, merchant's storehouse, station platform, shipping station, harbour.Fork truck is a propulsion source with combustion engine or storage battery generally, the pallet fork that is installed on the goods shelf has dipping and heaving, what have also can traversing, longitudinal extension, but the fork truck of prior art, when stretching, pallet fork needs big power and big counterweight, make center of gravity that pallet fork starts shipment goods near the fork truck front-wheel, otherwise fork truck can overturn forward, have safety hazard.This has limited freight transport volume and purposes again.

Summary of the invention

The purpose of this utility model provides a kind of box pallet fork car functions expanding arm, be applicable to various fork trucks, has the ability that long-distance moves goods, can finish cargo handing having under platform, no platform and the field work condition, the operating efficiency height, labour intensity is low, simplifies the big power of prior art, big counter weight construction, cost-cutting.

The purpose of this utility model is achieved in that a kind of box pallet fork car functions expanding arm, the goods shelf that is promoted by bont is housed on the door frame of this fork truck, the longitudinal extension arm is housed on goods shelf, this telescopic boom front end connects the front end goods shelf, the affixed pallet fork of front end goods shelf, rotating left and right bogie wheel is equipped with near pallet fork in the lower end of this front end goods shelf.

The structure of described telescopic boom is: left and right two groups of extensible member symmetries, isometric, every group of extensible member has some long connecting rods of Denging, per two connecting rods middle part hinge part, every connecting rod two ends and adjacent connecting rod are hinged to rhombus with lateral connecting rod, the hinged left and right two groups of extensible members of this lateral connecting rod, in its two preceding, the most last connecting rods, its downward-sloping interlinking lever end is articulated in the lower end of front end goods shelf and rear end goods shelf respectively with hinge pin, its acclivitous interlinking lever end is a hinged slide shaft respectively, and this slide shaft is contained in respectively in the vertical chute on front and back ends goods shelf top;

In lower hinge one driving oil cylinder of rear end goods shelf, the piston rod end of this oil cylinder is articulated on the downward-sloping connecting rod of rear end goods shelf.

The front end face of described front end goods shelf is equipped with liftable retaining shelf, and the center of top of these retaining shelf is connected with the device of overstocking that stretches out forward.

The utility model has following actively useful effect:

1. be applicable to various fork trucks, do not change former forklift truck properties substantially after installing this arm additional.

2. do not need manually auxiliary, can finish cargo handing (truck) under the platform condition having.

3. do not need artificial assisting, can under no platform condition, finish cargo handing (truck).

4. as resolving fork truck cross-country walk system, install this arm additional and can finish cargo handing under the field condition (truck).

5. be specially adapted to the loading and unloading of army's case dress ordnance property.

This product with goods long-distance Shift of Focus to bogie wheel, eliminated required big power and the big counterweight of remote mobile goods under the exhibition arm state.

The fork truck volume that this development arm is housed is little, operating flexibility, can be in narrow place operation; Goods shelf is provided with transverse-moving mechanism and the mechanism of protracting, and alignment box is stitched easily, and can tear the trapezoidal buttress of sign indicating number open; Noise is low, easy to operate, reliability is high, and labour intensity is low.

The fork truck that this development arm is housed is mainly used in the storehouse, in station platform and the train case object dress goods and materials load and unload, short-distance transport and tear palletizing operation open, also can be used for towage in the storehouse.

The fork truck of this exhibition of being equipped with arm when the identical ability of starting shipment, does not need big power and big counterweight; / 5th of an only suitable prior art fork truck of its cost.
