Abstract
The utility model provides an anticreep rail wheel, hoist and dolly and cart thereof to prevent the derail emergence of phenomenon of crooked when operation hoist of wheel and dolly and cart, wherein hoist and dolly and cart include anticreep rail wheel. This anticreep rail wheel comprises tire tread and rim and is opened the annular slot that has the cross sectional shape to be arc at tire tread and rim joint department, has avoided anticreep rail wheel by the phenomenon of track jack -up when crooked operation to the derail emergence of phenomenon of hoist and monkey, cart has effectively been prevented. And simultaneously, annular slot cross sectional shape is convex, can effectively avoid stress concentration, reduce frictional force between anticreep rail wheel and guide rail.
Description
Technical field
The utility model relates to crane field, particularly relates 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 described in the utility model, 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 problem to be solved in the utility model 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 utility model can prevent wheel deflection motions by track jack-up time derailing situation generation.
Meanwhile, the purpose of this utility model is also to provide and uses 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 utility model 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 utility model 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 utility model 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 utility model 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.

In other embodiments, the cross sectional shape of the cannelure described in embodiment 1 of derailing wheel can also be the shape such as oblong, triangle.
The embodiment of hoisting crane:
This hoisting crane comprises cart and dolly, and cart and dolly comprise wheel separately, 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 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.
