Abstract

The utility model discloses a double-trolley portal crane, and aims to design a double-trolley portal crane meeting use requirements of portal cranes and enabling the position of a lifting object to be not limited by an operating position of a trolley. The technical scheme is that the double-trolley portal crane includes a main beam, wherein an inner rail is arranged on the main beam; a lower trolley is assembled on the inner rail; an outer rail is assembled on the main beam; an upper trolley is assembled on the outer rail; and the trolley body of the upper trolley is higher than that of the lower trolley. The double-trolley portal crane has a reasonable structure, and is convenient to use, the suspension centers of the two trolleys approach to be greatest extent, besides, the operating positions of the two trolleys are more flexible, near to an end beam.

Description

A kind of two trolley gantry crane
Technical field:
The utility model relates to transfer crane, particularly a kind ofly is applicable to the transfer crane that double trolley lifts.
Background technology:
Present transfer crane is used comparatively extensive, especially two trolley gantry crane, practicality is stronger, and it is lifted the object that is hoisted by two dollies by two dollies are set at girder, finish the task of hoisting, but two dollies are owing to be in the same plane, and the run location of dolly on girder is limited, especially near the position of end carriage the time, often make the weight that is hoisted to arrive the desired location fully, give and use enterprise to bring more inconvenience.
Summary of the invention:
The purpose of this utility model is a kind of use that can satisfy transfer crane of design, and the position of the object that hoists is not subjected to the two trolley gantry crane of trolley travelling position limitation.
The technical solution of the utility model is, a kind of two trolley gantry crane, and it comprises girder, it is characterized in that: be provided with inner orbit at girder, be equipped with lower dolly on the inner orbit, be equipped with outside track at girder, be equipped with dolly on the outside track, the car body of upper dolly is higher than lower dolly.
The utility model is rational in infrastructure, and is easy to use, and the suspension centre of two dollies can farthest approach, and the run location of two dollies is also more flexible simultaneously, all can be near the position of end carriage.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Describe by reference to the accompanying drawings embodiment in detail, embodiment of the present utility model is a kind of two trolley gantry crane, it comprises girder 1, the girder both sides are provided with supporting leg 4, are provided with lower link 3 at girder, and lower link is provided with outside track 9, be equipped with dolly 2 on the outside track, be provided with lower girder 6 at lower link, lower girder is provided with inner orbit 7, is equipped with lower dolly 8 on the inner orbit, the car body of upper dolly is higher than lower dolly, is provided with intermediate rod 5 between supporting leg and lower girder.The utility model raises the car body of outer dolly, so that upper dolly is higher than lower dolly, two each self-operatings of dolly, not not in one plane, and all can move to the position near end carriage, at dolly a plurality of suspension centres are installed, can according to using needs, be chosen, single dolly also can be finished the lifting task, two dollies lift also and can use, so that the use of transfer crane is more flexible, result of use is better, the utility model is rational in infrastructure, be convenient to use, can reduce the position limitation of the weight that hoists of transfer crane, improved the production efficiency of transfer crane.
