Abstract
An elevator wheel can avoid biting rail, which is characterized in that: the tread of the elevator wheel is a wheel arc surface corresponding to the rail arc surface.
Description
Technical field
The utility model relates to wheel, is specifically related to hoisting crane preventing gnawing rail wheel.
Background technology
Wheel is a constituent elements of crane travel mechanism.Wheel is by wheel fate three classes, i.e. two-wheel edge wheel, single-wheel edge wheel or do not have the wheel rim wheel.Present self-propelled operating unit, every hoisting crane generally is equipped with four two-wheel edge wheels, half is a driving wheel, crane or dolly are in motion process, under normal operation, keep certain clearance between crane locomotive wheel rim and the track, the width of general wheel tread is than the big 40MM of orbital head width, have one side of wheel rim to should be about 10MM with the track side surfaces gap, because track is installed and the wheel defective mounting, wheel just can not move in the middle of the track tread, wheel rim contacts with track side surfaces, produce horizontal lateral thrust, cause the friction and the wearing and tearing of wheel rim and track, the so-called rail of gnawing.At present the hoisting crane of usefulness have have more than 80% in various degree gnaw the rail phenomenon, gnaw rail and can produce following bad consequence: the service life of 1. reducing wheel, the wheel of middle rank working level hoisting crane through quenching, under normal operation circumstances, can use 10 years or the longer time, but gnaw the service life that rail shortens wheel in various degree, serious can only use one or two years, even only some months just needs to change; 2. track wearing and tearing: gnaw rail for a long time, the track both sides of can wearing and tearing can grind step with track when serious, even cause track to scrap; 3. increase running resistance: gnaw the serious hoisting crane of rail, running resistance increases by 1.5～3.5 times than the resistance of normal operation, and big like this running resistance forces operation motor and the long-term overload operation of transmission device.
Summary of the invention
The purpose of this utility model is: a kind of hoisting crane preventing gnawing rail wheel is provided, eliminates hoisting crane and gnaw the wheel phenomenon, prolong wheel service life, reduce maintenance cost.
Technical solution of the present utility model is: the tread of the wheel of this hoisting crane is a cambered surface, and the wheel tread cambered surface is consistent with track top cambered surface.
During installation, two wheels at homonymy in four wheels of hoisting crane are the cambered surface wheel, and two wheels of opposite side are the plane wheel.Because the wheel cambered surface of hoisting crane one sidecar wheel and the track cambered surface of track are coincide, the cambered surface wheel will be exercised along the track straight line when operation, and hoisting crane another side wheel tread is the plane, and the tread width is bigger than orbital head width, when gauge changes, can compensate, gnaw a rail difficult problem, prolong wheel service life thereby solved hoisting crane, reduce maintenance cost, guaranteed traveling comfort.
Description of drawings
Fig. 1 is former wheel and track structure scheme drawing.
Fig. 2 is the utility model car wheel structure scheme drawing.
Fig. 3 is the utility model wheel and the track structure scheme drawing of Fig. 2.
Among the figure: 1. wheel, 2. track, 3. wheel cambered surface, 4. track cambered surface.
The specific embodiment
As shown in Figure 2, the tread of the wheel 1 of this hoisting crane is a wheel cambered surface 3, and wheel cambered surface 3 is consistent with track cambered surface 4.
During installation, two wheels at homonymy in four wheels of hoisting crane are the cambered surface wheel, and two wheels of opposite side are the plane wheel.Because the wheel cambered surface 3 of hoisting crane one sidecar wheel 1 is coincide with the track cambered surface of track 24, the cambered surface wheel will be exercised along the track straight line when operation, and hoisting crane another side wheel tread is the plane, and the tread width is bigger than orbital head width, when gauge changes, can compensate, gnaw a rail difficult problem, prolong wheel service life thereby solved hoisting crane, reduce maintenance cost, guaranteed traveling comfort.
Claims (2)
1. hoisting crane preventing gnawing rail wheel, it is characterized in that: the tread of the wheel of this hoisting crane (1) is wheel cambered surface (3), and wheel cambered surface (3) is consistent with track cambered surface (4).
2. hoisting crane preventing gnawing rail wheel according to claim 1 is characterized in that: two wheels at homonymy in four wheels of hoisting crane are the cambered surface wheel, and two wheels of opposite side are the plane wheel.
