Having the beneficial effects that of the application is as described below:

Cantilever beam in the application crane can stretch out between crane locomotive to outdoors or directly lifting goods to workshop, next door；Not only Workshop, the next door goods of cart traffic direction end points can be lifted by crane, and cart can be lifted by crane and run the goods in railway line side workshop； Owing to the cantilever beam of the application is arranged at below dolly and girder, cantilever beam directly can rise by stretching into workshop, next door below support rail beam Hoisting thing, or can directly stretch out the workshop operation outdoors of cart traffic direction, therefore present techniques feature can realize the application Purpose；After lifting goods, by electric block moving along cantilever beam, or by the rotation of cantilever member, or by running The movement of dolly, or by the motion of crane, or by aforementioned four integrated motions, the goods of lifting can be hung The place needed to this workshop；Carry out outdoors in the workshop, next door or workshop with workshop surrounding to use other during goods handing-over The transhipment of transporting equipment, improves efficiency.

Running trolley (3) in the application is above girder, and can move back and forth along girder two ends, is suitable for large span car Between use；Two anti-roller devices are respectively installed in running trolley both sides, can play " safety hook " effect, the rolling in anti-roller devices Wheel is pressed on rail and can run, and cantilever beam overload both can have been avoided to produce running trolley rollover and ensure that safety, can guarantee that again fortune Wheel on row dolly all rail do not upwarp, it is ensured that running trolley runs always, such running trolley use singly drive, Dolly driving aspect is cost-effective；Adjust pad (337) suitable thickness by regulation, make the roller in anti-roller devices and rail (22) it is connected rightly, rolling can be press against, it is ensured that trolley travelling is smooth and easy.

Two adhesion wheel groups in the application drive car are coupled together by spline box coupling (325), spline Nested structure is simple, and the little handling ease of size, especially spline housing shaft coupling external diameter are little, so can be selected for " three conjunctions that centre-to-centre spacing is little One " reductor, shaft coupling overall dimensions not with reductor interfere, low cost；" three-in-one " reductor, small in volume, The advantages such as noise is little, easy for installation.

On running trolley in the application, anti-roller devices is arranged on inside girder, and it is advantageous in that the lashed cable (123) chosen on electricity frame Anti-roller devices will not be wrapped in.

The cable on running trolley in the application can be connected with the lashed cable (123) chosen on electricity frame (121) on girder side, hangs Can move back and forth choosing left and right on electricity mounted track on cable, such electric power can run power supply back and forth by lashed cable along with running trolley.

The cantilever crane of the application is suitable on the metope column the most on one side of workshop setting up bracket to lay track, and another side uses car Between the environment of track；On end carriage in crane semi portal, cart actuating device runs on column track, the cart on sill Driving means is run in the track of workshop；Cantilever beam can reach workshop, next door in the middle of supporting rack to carry out lifting or unloading goods.

End carriage in the application crane uses two balances end carriage (102) and a middle connecting rod (101) to be formed by connecting；Under Crossbeam is formed by connecting by two balances grade beam (302) and a middle tie-beam (301)；Such combination beam is supporting organizes car more Wheel, can use the wheel group of small-wheel-diameter, and the sectional dimension making combination beam is little, and constructions cost is low, and can solve crane large-tonnage Little wheel load problem.

Rotating mechanism in the application crane has the gear pair transmission of a pair exposed drive, by gear wheel, little gear not Set with the number of teeth, user's precise requirements to the cantilever beam rotary speed of crane can be met, it is to avoid individually selection standard reductor General speed ratio and the error of the cantilever beam rotating speed that produces and actual demand；Driving means is combined with vertical type speed reducer (change gear) by motor, Vertical type speed reducer (change gear) band mounting flange and output shaft；Driving means is bolted on reductor bearing, and reductor bearing is solid It is scheduled on trolley frame.

The bearing block in rotating mechanism in the application crane and suspension rod axle connect and are born up gravity by thrust bearing, suspension rod axle by The most spacing firmly radial position of bearing A and bearing B, it is ensured that suspension rod axle can bear the biggest axial force and radially not offset, thus Ensureing that driving means axiality is good, hinged cantilever component is laborsaving；Stop nut and suspension rod male thread in cantilever member connection connect After, then having bolt (99) to couple together through the diameter of stop nut and suspension rod axle, it is to avoid stop nut unclamps, safe and reliable.
