The beneficial effect of the application is as described below：

Cantilever beam in the application crane can be stretched out between crane locomotive to directly lifting goods outdoors or to next door workshop；Not only The next door workshop goods of cart traffic direction end points can be lifted by crane, and the goods in cart running track line side workshop can be lifted by crane； Because the cantilever beam of the application is arranged at below dolly and girder, cantilever beam can directly be risen by stretching into next door workshop below support rail beam Hoisting thing, or the workshop operation outdoors of cart traffic direction can be directly stretched out, therefore present techniques feature can realize the application Purpose；After lifting goods, by motion of the electric block along cantilever beam, or the rotation by cantilever member, or pass through operation The movement of dolly, or the motion by crane, or by foregoing four integrated motion, the goods of lifting can be hung The place needed to this workshop；It need not can be borrowed when carrying out goods handing-over outdoors with the next door workshop of workshop surrounding or workshop other The transhipment of transporting equipment, improve efficiency.

The cantilever crane of the application be suitable for workshop only have set up on the metope column of one side bracket laying track, another side uses car Between track environment；Cart running gear is run on column track on end carriage in crane semi portal, the cart fortune on grade beam Luggage is put to be run in the track of workshop；Cantilever beam can also reach next door workshop among supporting rack and be lifted or unloaded goods.

Running trolley (3) in the application can move back and forth in the top of girder along girder both ends, be suitable for large span car Between use；Two anti-roller devices are respectively installed in running trolley both sides, can serve " safety hook ", the rolling in anti-roller devices Wheel is pressed on rail and can run, and can both avoid cantilever beam from overloading and produce running trolley rollover and ensure that security, and and can ensures fortune Wheel on row dolly all rail do not upwarp, it is ensured that running trolley is run always, and such running trolley is driven using single, It is cost-effective in terms of dolly driving；By adjusting adjust pad (337) suitable thickness, make the roller and rail in anti-roller devices (22) rightly it is connected, rolling can be press against, ensures that trolley travelling is smooth.

Two adhesion wheel groups in the application drive car are risen by spline box coupling (325) and floating axis connection Come, spline housing is simple in construction, and the small handling ease of size, especially spline housing shaft coupling external diameter are small, and it is small that centre-to-centre spacing so can be selected " three-in-one " reductor, shaft coupling do not interfere with reductor, and cost is low；" three-in-one " reductor, small in volume, Noise is small, it is easy for installation the advantages that；The not parallel error of larger axis can be compensated by wherein being coordinated using floating axle and spline housing.

The lashed cable (123) chosen on electric frame (121) connection beside the cable and girder on running trolley in the application, electric power Power supply can be run back and forth with running trolley by lashed cable.

Rotary limit device is provided between suspension rod axle and trolley frame in the application, by safety ruler (583) and two travel switches (581) form, safety ruler is arranged on suspension rod axle upper end, and travel switch is arranged on trolley frame upper surface, is more convenient installation and adjustment； When safety ruler (583) swing rod one end is advantageous in that spline tooth connection corresponding with suspension rod axle provided with splined hole (5833), safety The angle direction of chi is adjusted well, and suspension rod axle can be inserted in the direction arbitrarily needed and is fixed, keeps most suitable position；Have Rotary limit device, can avoid cantilever beam from excessively rotating, prevent the cable (6) of electric block to be wrapped in hanging in cantilever member Be torn on hanging seat (52) because the cable (6) of electric block be draw from the junction box on trolley frame it is ensuing.

There is the gear auxiliary driving of a pair of elevating arc transmissions in rotating mechanism in the application crane, pass through big elevating arc, small fan tooth The different numbers of teeth setting of wheel, can meet precise requirements of the user to the cantilever beam rotary speed of crane, avoid direct selection standard Reductor it is general speed than and caused cantilever beam rotating speed and the larger error of actual demand；It is driven using elevating arc, rotation can be made Drive device in mechanism uses horizontal speed-reducer, reduces setting height(from bottom).

Bearing block and suspension rod axis connection in the application rotating mechanism bear gravity by thrust bearing, and thrust bearing is arranged on bearing block Top, it is easy to dismount；The inner hole structure of bearing block is simply easy to process；Sleeve (43) is that high-abrasive material makees sliding bearing use, The fit clearance of suspension rod axle is reduced, increases rotational stabilization, increases the axiality of drive mechanism, cantilever member rotates laborsaving；It is anti- After loose nut A and suspension rod axis connection, then the connection by bolt (46), anti-loose effect is played, ensures rotating mechanism safety.

Cantilever member in the application is with after suspension rod axis connection, after connecting positioning with suspension rod axle thread by stop nut, then using spiral shell The diameter of bolt (99) through stop nut and suspension rod axle connects, and avoids stop nut from loosening, securely and reliably, stop nut On blind hole lever can be facilitated to insert, it is light to pull nut, easy disassembly and maintenance.
