Description
Technical field
The present invention relates to revolving support technologies, and in particular to the revolving support technology for Giant Wheel carriage.
Background technique
Recently as the improvement of people's living standards, people are also all with day to the craving degree of recreation ground, amusement facility
Increase.Ferris Wheel is as the significant facility in amusement facility, the favor by recreation ground and large-scale square all the time.Compared to
The amusement facility of a series of high speeds such as roller-coaster, big pendulum, high inertia, Ferris Wheel have it is steady comfortable, ascend a height and hope scape, audient face
A series of advantages such as wide.
Successively there are some Ferris Wheels in the development course for Chinese industry of travelling of leafing through, the eighties in last century, China,
Wherein most is import overseas equipment and its height mostly at 50 meters or less.2002, with first height of China
Ferris Wheel " Shanghai traffic cycle " completion for surpassing 100 meters, Giant Wheel production domesticization also accelerated development.2006, " star in Nanchang "
Ferris Wheel is built up, and it is the highest Ferris Wheel of world wide inner height at that time that height, which is 160 meters,." star in Nanchang " has attracted entirely
The extensive concern of world's media, so far " star in Nanchang " are still that whole world disk diameter is maximum, the highest truss of height
Formula Ferris Wheel, building up for it also indicate that the Chinese industry of travelling has reached a new milestone, the sector domestic project teacher's
Designed capacity, the manufacturing ability of heavy steel member, erectility have obtained being widely recognized as international counterparts.Although large size is seen
Look at vehicle degree domestic it is very universal and improved day by day, but what these Ferris Wheels were mostly equipped with is that can only at most accommodate 4
The middle-size and small-size carriage of tradition of~6 people.
The large-scale carriage that highly 100 meters or more of Giant Wheel and being equipped with can accommodate 20 people or more is Ferris Wheel instantly
The main trend of development, but the Giant Wheel configured with carriage truly at home Ferris Wheel market still in sky
White state.
Ferris Wheel carriage common at present mostly uses pivoting support to encircle formula structure, general to use 2 pivoting supports
Carriage main structure is fixed therein circle, and outer ring is connected with Ferris Wheel turntable, and cab interior is equipped with servo levelling device, moment
Detect carriage ground level state.When Ferris Wheel operation, carriage rotates and generates the variation of position, angle with Ferris Wheel, passes
Sensor monitors carriage ground level state, once carriage ground and horizontal plane generate inclination angle, sensor gives servo motor signal,
Servo motor operation driving pivoting support inner ring rotation, makes carriage ground keep horizontality again to correct inclination angle.Letter and
Yan Zhi, the device are exactly constantly to correct inclination angle in Ferris Wheel operational process to keep carriage holding horizontal, and passenger walks in carriage
Dynamic steady, view Shu Yi.It can be seen that obliquity sensor, pivoting support, servo motor are the main members of this kind of levelling devices
Part.
By the carriage research to built Ferris Wheel, it is found that the pivoting support of carriage there are following characteristics:
(1) low load with strong power, the wasting of resources.
The diameter of pivoting support used is generally more than 3 meters in carriage, consult technical data it can be found that: 3 meters of diameter or more
Pivoting support, antidumping weight bearing power is near kiloton rice.The use occasion of carriage is reviewed, even if pressing each carriage carrying
40 people (everyone weight is based on 70 kilograms), for a total length is 8 meters of carriage, 40 people stand on worst position,
Moment of flexure to the pivoting support being mounted in the middle part of carriage are as follows: 40 people × 70 kilogram × 3 meter=8400 kilogram-metre=8.4 ton rice；
And it is much smaller to actually use the load that load ratio can be born, therefore seeming ample using pivoting support in this occasion has
It is remaining.Furthermore and be completed Ferris Wheel carriage used two sets of pivoting supports, the diameter of single pivoting support is about 3.2 meters,
The redundancy of bearing capacity is excessive, causes very big waste.

Therefore manufacturing cost is also very high.In fact, fixing the actual stress of the pedestal of their Internal and external cycles due to the stress very little of pivoting support
It is also at very low level.
(3) loop material is forging inside and outside pivoting support, at high cost.
The steel of identical chemical component can make the crystal phase tissue of steel more if being forged and pressed repeatedly again after cast molding
Add densification, the mechanical performance of material can be improved significantly.Therefore the Internal and external cycle of general pivoting support is all made of press forging.But
Be forging blank dimension surplus it is big, machining cutwork amount it is larger, thus its manufacturing cost is also higher.Since carriage is turned round
The service load of bearing is relatively small, if still using alloy steel forging to manufacture pivoting support Internal and external cycle, just in this occasion
Seem excessively luxurious.

Wherein, the wheel rim 113 in two groups of wheeled adaptive supporting systems 110 is bent using steel plate, two groups of wheel rim tops
The method that portion uses steel plate to weld, bottom make the two be connected using the method that steel pipe 115 (Ferris Wheel turntable crosspiece 115) welds
It connects, after two groups of wheel rims mutually weld connection with steel pipe using steel plate, just forms a rigidity and preferably connect pedestal, bottom end face
It is bolted equipped with connecting flange 114 and Ferris Wheel turntable, entire wheel rim forms one with Ferris Wheel turntable again after the completion of connection
It is whole, self structure rigidity is strengthened each other.
Compared to the composite structure that traditional carriage generallys use pivoting support and installation pedestal, this wheeled adaptive bearing system
System 110 wheel rim with connect pedestal by being welded and being mostly that steel plate twists, be not only easy to purchase in this way, Er Qiejia
Work is convenient, cost of manufacture is lower, compared to the manufacturing of pivoting support, shortens its delivery cycle.Due to wheel rim 113 and even
Connect the welding of both pedestals and form one, which also improves the overall stiffness of wheel rim, make wheel rim when Ferris Wheel operates normally more
Stablize.
Every group of wheeled adaptive supporting system 110 is made of 2 main wheel 111 and 4 side wheels 112 in this example, i.e., entirely
One shares 4 main wheels and 8 side wheels in system.Wherein 4 main wheels are supported on car cab 120 is rotatable in wheel rim 113, and

As a result, in Ferris Wheel operation process, main wheel 111 is concentric time automatic with Ferris Wheel operating in 113 inside of wheel rim
Turn and there is good tracking adaptability, 4 main wheels have born the weight bearing of entire carriage, and each main wheel can about be born
2.5 tons of weight, about 10 tons of total weight bearing of 4 main wheels, which matches with carriage and passenger weight summation.
There are also 4 side wheels in single group wheel systems, are cooperated by the rolling of side wheel and 113 side of wheel rim, can effectively be limited
The longitudinal sliding motion of carriage processed is to help servo-actuating device accurate positioning that gear drive central plane is made to be maintained at same flat as far as possible
In face, the maximization of leveling efficiency can be reached in this way and make gear drive stress equalization, improve the reliability and stability of system.
When carriage bears front wind load, the active force of wind load is mainly undertaken by side wheel.When passenger stand at carriage end face,
Since both ends unbalance stress carriage can more or less generate inclination, when encountering such operating condition, side wheel just bears entire carriage
Antidumping function.
Thus the Giant Wheel carriage scheme constituted is when being worked: main wheel and side wheel are equivalent to back in wheel systems
Turn bearing inner ring, when Ferris Wheel operates normally, the variation of position and angle, sensor prison occur with the rotation of Ferris Wheel for wheel rim
Whether horizontal survey cab interior ground, once generating inclination angle issues deviation model to servo controller immediately, servo controller is then
It is instructed to servo motor sending action, servo motor drives gear drive, and gear is connected with carriage steel frame, and main wheel is fixed on steel
On frame, to make main wheel side roll in wheel rim, correcting carriage angle changing makes ground in carriage return horizontality, in turn
Reach levelling effect.
