Abstract
The invention provides derailing prevention wheels, a crane, a trolley of the crane and a cart of the crane. The phenomenon of derailment of the crane, the trolley of the crane and the cart of the crane caused when wheels run aslant is prevented. The crane, the trolley of the crane and the cart of the crane comprise the derailing prevention wheels. Each derailing prevention wheel comprises a wheel tread and a rim; an annular groove with an arc section is formed in the combination position of the wheel tread and the rim; the phenomenon that the derailing prevention wheels are ejected by tracks when running aslant is avoided, and therefore the phenomenon of derailment of the crane, the trolley of the crane and the cart of the crane is prevented effectively. Meanwhile, the sections of the annular grooves are in the arc shape, stress concentration can be effectively avoided, and force of friction between the derailing prevention wheels and guide rails is reduced.
Description
Technical field
The present invention relates to crane field, particularly relate to a kind of derailing wheel, hoisting crane and dolly thereof and cart.
Background technology
Be applied to the dolly of hoisting crane and hoisting crane at present, the car wheel structure form of cart have two rim construction, single rim construction and without rim construction, two rim construction wheel and single rim construction wheel have been referred to as rim construction wheel.
Have in rim construction wheel above-mentioned, generally use arc transition structure as shown in Figure 1 between current wheel rim and tread, there is being made up of wheel rim 1, arc-shaped transitional surface 2 and tread 3 wheel flange wheel of arc transition structure.When have arc transition structure have wheel flange wheel deflection to run time, the arc-shaped transitional surface 3 of side can and track topside contacts, cause that wheel is passive to be lifted, and then form derailing.
Adopt arc transition structure between wheel rim and tread in prior art, when the crooked operation of wheel, arc-shaped transitional surface can with track tip contact, cause that wheel is passive to be lifted, and then form derailing.And use the derailing wheel having cannelure of the present invention, when the crooked operation of derailing wheel, the form of cannelure make derailing wheel other parts except tread not easily with rail contact, and then derailing wheel is not easily by track jack-up, thus effectively prevent the generation of derailment occurring.Simultaneously because the existence of cannelure decreases the possibility of other parts and rail contact beyond derailing wheel tread, therefore this derailing wheel is at reduction resistance, alleviates to gnaw rail and raising derailing wheel life aspect is also very helpful.
Further, the cross sectional shape of described cannelure is circular arc, stress effectively can be avoided to concentrate, reduces friction force between derailing wheel and guide rail while preventing derailing situation from occurring.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of derailing wheel for crane field, for common have arc transition structure have a wheel flange wheel deflection motions time wheel to be caused the situation of derailing, the present invention can prevent wheel deflection motions by track jack-up time derailing situation generation.
Meanwhile, the present invention also aims to provide and use the above-mentioned hoisting crane of derailing wheel and the dolly of hoisting crane and cart.
For solving the problems of the technologies described above, derailing wheel provided by the present invention by the following technical solutions: a kind of derailing wheel, comprises wheel rim and tread, has the cannelure with derailing wheel concentric at tread and wheel rim joint.
The cross sectional shape of described cannelure is circular arc.
Hoisting crane provided by the present invention is by the following technical solutions: a kind of hoisting crane, comprises wheel, and wheel comprises wheel rim and tread, and tread and wheel rim joint have the cannelure with derailing wheel concentric.
The cross sectional shape of described cannelure is circular arc.
Monkey provided by the present invention is by the following technical solutions: a kind of monkey, comprises wheel, and wheel comprises wheel rim and tread, and tread and wheel rim joint have the cannelure with derailing wheel concentric.
The cross sectional shape of described cannelure is circular arc.
Crane provided by the present invention is by the following technical solutions: a kind of crane, comprises wheel, and wheel comprises wheel rim and tread, and tread and wheel rim joint have the cannelure with derailing wheel concentric.
The cross sectional shape of described cannelure is circular arc.

The embodiment of monkey:
This monkey comprises wheel, and the structure of wheel is identical with the structure of the embodiment 1 of above-mentioned derailing wheel, and it will not go into details herein.In other embodiments, derailing wheel can also be the derailing wheel in the embodiment 2 of above-mentioned derailing wheel.
The embodiment of crane:
This crane comprises wheel, and the structure of wheel is identical with the structure of the embodiment 1 of above-mentioned derailing wheel, and it will not go into details herein.In other embodiments, derailing wheel can also be the derailing wheel in the embodiment 2 of above-mentioned derailing wheel.
