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, under cart very on beam Running gear is run in the track of workshop；Cantilever beam can reach next door workshop among supporting rack and be lifted or unloaded goods.

End carriage in the application crane is formed by connecting using two balance beams (102) and a middle connecting rod (101)；Under Crossbeam is formed by connecting by two balance grade beams (302) and a middle tie-beam (301)；Such supporting multigroup car of combination beam Wheel, the wheel group of small-wheel-diameter can be used, makes that the sectional dimension of combination beam is small, and constructions cost is low, and can solve crane large-tonnage Small wheel load problem.

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；It is appropriate thick by adjusting adjust pad (337) Degree, makes the roller in anti-roller devices be rightly connected with rail (22), can press against rolling, ensures dolly fortune Row is smooth, the driving of running trolley list, cost-effective in terms of dolly driving.

The application running trolley is driven using the drive car (32) of independent no mechanically contact, and such part packet property is good, It is easy to installation and maintenance；Use " three-in-one " reductor, small in volume, noise are small in the application drive car； Its output shaft, which is the hollow shaft with spline, to be coordinated with axletree and facilitates easy, and its output shaft shared trolley frame vertical with motor shaft Horizontal space is small.

The lashed cable (123) chosen on electric frame (121) connection beside the cable and girder on running trolley in the application, operation Conduction rack (122) on dolly chooses one movement of lashed cable, and such electric power can run power supply back and forth by lashed cable with running trolley.

Rotary limit device (58) is provided between cantilever member and running trolley in the application, is avoided that cantilever beam excessively rotates, It is no more than 360 degree of angles to rotate, prevents the cable (200) on electric block to be wrapped in the Holder for hanging household utensiles (52) in cantilever member It is upper and be torn because the cable (200) of electric block be draw from the junction box on running trolley it is ensuing.

Bearing block in rotating mechanism and suspension rod axis connection in the application crane bear lifting power by thrust bearing, suspension rod axle by The spacing firmly radial positions of bearing A and above and below bearing B, ensure that suspension rod axle can bear very big axial force and not offset radially, so as to Ensure that drive device axiality is good, hinged cantilever component is laborsaving；Drive device output shaft insertion in rotating mechanism is connected to suspension rod In the axis hole of axle one end, power drive is simple in construction, and transmission accessory is few, mechanism take up space it is small, it is compact-sized；Stop nut After being connected with suspension rod axle thread, then the diameter for having bolt through stop nut and suspension rod axle connects, and avoids stop nut from unclamping, Securely and reliably.
