Abstract

The utility model relates to a novel elevator for goods, the elevator for goods is widely suitable for the conveying operation which is steeplifting and downward between two layers in the system of unit convey for goods. The elevator for goods comprises an upright post, a left charge platform, a cable, a driving device, a guide track, a retractable fork, a right charge platform, an adjustable bolt, a motor, a speed reducer and a driving wheel. The elevator for goods is characterized in that the elevator is provided with two loading goods platforms (2, 7), and the two loading goods platforms are respectively installed at the left and right sides of the upright post (1). The left and right charge platforms are respectively fixedly connected with the head and tail ends of the cable (3) through the adjustable bolt (8). The cable (3) coils on the driving wheel (11) of the driving device (4) which is above the upright post. The elevator for goods has the advantages that the elevator for goods can reduce the driving power, convey goods and the work efficiency can be enhanced one time, meanwhile, the elevator for goods has simple structure.

Description

Two loading platforms back and forth move elevator

The utility model relates to a kind of novel cargo hoister, and this cargo hoister is widely used in the unit cargo movement system transport operation of vertical-lift between two aspects, decline.

General common cargo lift drives a loading platform by a cover actuating device, and loading platform rose when actuating device was just changeing, and loading platform descends during counter-rotating.The horsepower output of actuating device equals the product of loading platform (together with goods) weight and rising or falling speed.In order to reduce elevator power, some elevator adopts " counterweight " to come balance loading platform self weight and a part of cargo weight, thereby makes driving power reduce to make an appointment with half.

The purpose of this utility model provides a kind of pair of loading platform device of counterbalanced weight each other, and making each loading platform is the carrier that transports goods, and plays another loading platform counterweight again.This novel cargo lift can make the working out of transporting goods double again when realizing that driving power is reduced to half.

The utility model is the (see figure 1) that realizes like this: this elevator is made up of column 1, left loading platform 2, cable wire 3, actuating device 4, guide rail 5, retractable fork 6, right loading platform 7, adjustable bolt 8.Column 1 is the carrying main body of this elevator, also is the guiding partss of the vertical operation of two loading platforms.The guide rail 5 that four parallel upright are arranged on the column, Fig. 1 are represented wherein two, and two guide rails are at the column front view back side in addition.Column is welded with the steel section bar.Loading platform 2 and 7 is carrying members of goods 12, and retractable fork 6 (also available other horizontal transmission device) is housed on the platform, is used to get/unload goods 12.Two loading platforms 2 of this elevator and 7 are installed in the and arranged on left and right sides of column 1 respectively.But two loading platforms 2 and 7 by adjustable bolt 8 respectively with the head and end fixed connection of cable wire 3.Cable wire 3 is wrapped on the drive wheel 11 of column 1 top actuating device 4, tightly meshes with drive wheel 11 by the wheel lining.Cable wire 3 is carrying and traction elements of two loading platforms 2 and 7.Also can replace cable wire with chain.Actuating device 4 is made up of electrical motor 9 (interior band brake), reductor 10 and drive wheel 11.Actuating device 4 drives oppositely back and forth operation of column both sides loading platform 2 and 7 by cable wire 3.Find out that thus two loading platforms are driven by cable wire, along the 5 upper and lower operations of column guide rail, left and right two loading platforms are the carrier that transports goods, again the counterweight of another loading platform each other.

Fig. 1 back and forth moves the structural representation of cargo lift for two loading platforms.

Fig. 2 is the actuating device scheme drawing.

This cargo lift mode of operation such as Fig. 1 represent that right side loading platform 7 is positioned at low layer now, and the left side loading platform is positioned at high level.When needs from low layer when high level transports goods, current position is that right loading platform 7 is got goods, 2 unloadings of left loading platform, after goods is got/is unloaded and finishes, actuating device 4 left-hand revolutions, left platform descends, right platform rises.Reduce to low layer when left platform, right platform promptly rises to high level, as representing that with long and two-short dash line the position improves in 1,2 among the figure.Left side loading platform pallet fork is got goods, simultaneously, and right loading platform pallet fork unloading.Two loading platforms like this are alternately carried out " right side gets/left side unloads-right a liters/left side falls-right side unloads/left side gets-right side falls/left side rises " cyclic program, realize goods by the transport operation of low layer to high level, and this is the transport operation mode that makes progress.When needs with goods when high level is carried to low layer, this elevator two loading platforms are alternately carried out " right side unloads/left side gets-right a liters/left side falls-right side gets/left side unloads-right side falls/left side liter " another cyclic program, are called downward transport operation mode.Above-mentioned two kinds of mode of operation can be selected or change to the electrical controller of this elevator as required.

Compare with the scheme that adopts two conventional cargo lifts (being the elevator that single loading platform does not have counterweight), this elevator scheme is owing to only need a cover actuating device, and driving power reduces half than no counterweight elevator, therefore, the total lifting driving power of this programme is equivalent to about 1/4th of the total lifting driving power of conventional scheme.Simultaneously, reduce greatly owing to promote power of motor, about the same in two pallet fork power of motor sums, and since the lifting operation flexible with pallet fork be that timesharing is carried out, therefore can be with a frequency converter to lifting motor and two pallet fork motor time sharing power supplies.As a same reason, other electrical controller generally also can be shared a cover, thereby further reduced the investment and the energy consumption of equipment.

In sum, the utility model advantage is: can significantly reduce driving power, the operating efficiency of transporting goods can Double, simultaneously simple in structure.
