The spring constant and the damping force are adjusted in accordance with the slide carriage inertia.

Description

The gantry crane that electric drive wheel drives

Technical field

The utility model relates to the gantry crane that a kind of electric drive wheel drives.

The utility model is applicable to and transports freight container, and they leave on the very narrow space and form narrow tunnel, and it must be crossed by gantry crane, so that extract or put down freight container.

Background technology

Gantry crane, so-called " standdle carrier " has the make of U-shaped.Four columns generally are installed on two bottom shell part, and bottom shell part is connected with a upper frame by column, and a raising legs is positioned on the upper frame, borrows it to catch, promote and transport freight container.Since generally must be on very narrow space with container stacking, the bottom of gantry crane must constitute narrow as far as possible.The actuating device that requires gantry crane in addition is low noise as far as possible and guarantees the good manoevreability of gantry crane.This utilizes traditional actuating device is inaccessiable, because parts such as its form king-sized unit by drg, retarder and actuating device, thereby the erecting by overhang on gantry crane reaches a size dimension, and it is not suitable for crossing tunnel narrow between the freight container of parking.

By the known a kind of gantry crane of DE 197 14 210 A1 with upper frame and underframe, its constitute at least two and turn to mutually.The wheel configuration that can turn to allows point accurately to transport freight container.Each wheel of gantry crane is at two-side supporting, and this causes gantry crane to have a width in the wheel zone, and this width is greater than the container width of half.Therefore between each freight container, be necessary for traveling gear and keep wide tunnel, consequently, lost a container width that is used for the wheel width equally in the both sides of a freight container, thereby the buyer of car is because the place that the width of wheel assembly need add for the gantry crane that travels, and this has lost the stacking area that is used for freight container.

Actuating device, wherein have only drg and retarder to be positioned at wheel and realize transmitting propulsive effort to wheel via imput shaft, produce such result, be actuating unit be installed on the underframe and via versatile spindle or chain to the wheel power transmission, thereby free movable parts form dangerous matter sources and noise source onboard.

Describe a kind of electrically operated single wheel drive device that is used for Operation Van among EP 0,812 718 A2, wherein be provided with a motor, its imput shaft drives the terminal gearing speed-reducer and of a rev down at its wheel that is provided with later.Single wheel drive should be able to realize the big speed range of vehicle when adopting commercial general-duty can hang down the motor of expense manufacturing, wherein the starting point of motor remains possible corresponding to the main gear scope and the higher speed of a motor vehicle of vehicle.One transmission gear shift device is set between motor and terminal gearing speed-reducer, and it can be changed between at least two rotating speed gear stages.This transmission gear shift device constitutes by power-transfer clutch and the convertible planetary gear apparatus of drg by one.This document does not illustrate whether electrically operated single wheel drive is suitable for using in gantry crane.Motor, retarder and drg do not cause compact actuating device by the configuration of described form yet, make it be applicable to the gate-type carrier-and-stacker as electrically operated single wheel drive, the latter has the car weight above 100 tons, and the make that each actuating device has more than the compactness of the power range of 75kW and electrically operated wheel drive requires to form very narrow wheel.In addition, the drg of the power that also do not combine of this wheel drive with a spring-loaded parking brake.

Known according to prior art not with the gantry crane of electrically operated wheel drive, wherein in each wheel each wheel have high driving power, constitute narrow, and motor, drg and retarder are arranged in wheel drive, make gantry crane when superpower, have only little width, and on wheel, do not have the parts of unlimited activity and form low noise driving in the wheel zone.

Summary of the invention

Therefore the purpose of this utility model is, develop a kind of gantry crane, by means of travelling in its narrow tunnel between each freight container is possible, it is low noise and low objectionable impurities that driving should reach, and do not have movable drive disk assembly and transmit superpower by wheel between framework and wheel.

This purpose reaches by the gantry crane with wheel drive of the present utility model.

Provide a kind of gantry crane according to scheme of the present utility model, it has the electrically operated wheel drive of a compactness, be included in the tire on the wheel rim that a wheel that turns to oil return line and cooling loop sticks, drg, sealing arrangement, motor, retarder, the input and output device and the Wheel bearing of energy, signal wire (SW) and cooling system conditioner, wherein the motor of flat configuration form is connected with wheel fork with the antitorque commentaries on classics of its housing ground.Motor shaft and one speed reducer are that the input stage of planetary gear apparatus is connected, and the wheel rim of wheel is tightened on its output stage, wherein between the output stage of planetary gear apparatus and housing drg are set, its therefore closely feud act on the wheel.

Described drg constitutes that can stop and drg power, and wherein parking brake is spring-loaded for automatic steering can hydraulically handle the running drg.Advantageously, the drg that will turn round constitutes wet multi-disk brake.

Advantageously, planetary gear apparatus is constituted two-stage.

In addition advantageously, Wheel bearing is installed between the planetary gear apparatus.

In addition advantageously, wheel fork constituted to turn to.In order to ensure operating reliability advantageously, a temperature sensor that is used for cooling system conditioner is set on wheel drive.Gantry crane can be equipped with a plurality of electrically operated wheel drive, and it is favourable having at least one actuating device in each side.

In addition advantageously, the brake resistance device is set on each actuating device, borrows it to drain braking energy.

Can constitute gantry crane on internal segment save space ground, wheel zone by gantry crane with electric drive wheel driving, and low noise ground drives gantry crane, wherein can transmit very big power, and for movable parts needn't be set between framework and wheel to the wheel translatory movement.

In addition, the braking energy major part can be drained via the brake resistance device by electrically operated actuating device, this causes little brake wear.

Motor has efficient preferably, and it causes little energy consumption.Because simple make, motor is more durable than other similar motors.By controlled drive motor, the accurate type of drive of vehicle is possible.
