Description

Wheel type self-adaptive supporting system and large-scale sightseeing car carriage

Technical Field

The utility model relates to a gyration is supported the technique, concretely relates to gyration support technique that is used for large-scale sight-seeing bus car.

Background

Along with the improvement of living standard of people in recent years, people have increasing desire for playgrounds and amusement equipment. Sightseeing vehicles have been favored in amusement parks and large squares as signage in amusement equipment. Compared with a series of high-speed and high-inertia amusement equipment such as roller coasters and large pendulums, the sightseeing bus has a series of advantages of stability, comfort, climbing height, view observation, wide audience range and the like.

Turning over the development course of the amusement industry in China, in the last 80 th century, tourists appeared in China in sequence, most of which are imported foreign equipment and the height of which is mostly below 50 meters. In 2002, as the first sightseeing vehicle with the height of over 100 meters in China 'Shanghai big turntable' is formed, the localization of the large-scale sightseeing vehicle is accelerated. In 2006, the sightseeing bus "Nanchang star" was built up, and the height of the sightseeing bus was 160 meters, which was the highest height in the world at that time. The Nanchang star attracts the wide attention of media all over the world, is still the truss type sightseeing vehicle with the largest diameter and the highest height of a turntable all over the world so far, and the construction of the Nanchang star marks that the Chinese amusement industry achieves a new milestone, and the design capability of engineers in China, the production and manufacturing capability and the installation capability of large steel components in the industry are widely accepted by international and peer groups. Although the localization degree of large-scale sightseeing vehicles is very common and increasingly perfect, the sightseeing vehicles are mostly equipped with traditional small and medium-sized cars which can only accommodate 4-6 people at most.

The current trend of the development of the sightseeing bus is that the large-scale sightseeing bus with the height of more than 100 meters is provided with the large-scale cage capable of accommodating more than 20 persons, but the real large-scale sightseeing bus provided with the large-scale cage is still in a blank state in the domestic sightseeing bus market.

At present, most of common sightseeing car cages adopt a pivoting support encircling structure, 2 pivoting supports are generally adopted to fix a main structure of the cage on an inner ring of the cage, an outer ring of the cage is connected with a sightseeing car turntable, and a servo leveling device is arranged in the cage to constantly detect the ground level state of the cage. When the sightseeing bus runs, the cage rotates along with the sightseeing bus to generate the change of position and angle, the sensor monitors the horizontal state of the ground of the cage, once the ground of the cage and the horizontal plane generate an inclination angle, the sensor gives a signal to the servo motor, and the servo motor runs to drive the inner ring of the slewing bearing to rotate, so that the inclination angle is corrected to enable the ground of the cage to be kept horizontal again. In short, the device continuously corrects the inclination angle in the running process of the sight-seeing bus to keep the lift car horizontal, so that passengers can walk stably in the lift car and have a comfortable view. It follows that tilt sensors, slewing bearings, servomotors are the main elements of this type of levelling device.

Through the research on the car of the built sightseeing bus, the slewing bearing of the car is found to have the following characteristics:

(1) the big horse pulls the trolley, and the resources are wasted.

The diameter of the slewing bearing used on the lift car is generally more than 3 meters, and the technical data can find that the slewing bearing with the diameter of more than 3 meters has the anti-overturning load capacity of about kilotonmeters. Contrary to the application of the car, even if 40 persons are carried in each car (each person weighs 70 kg), for a car with a total length of 8 m, 40 persons stand at the most unfavorable position, and the bending moment of the pivoting support installed in the middle of the car is: 40 people × 70 kg × 3 m 8400 kg m 8.4 ton m;

the actual load in use is much smaller than the bearable load, so that the use of the slewing bearing in such a case is more than sufficient. Moreover, the cars of the existing sightseeing vehicles all use two sets of slewing bearings, the diameter of each slewing bearing is about 3.2 meters, and the redundancy of the bearing capacity is overlarge, so that great waste is caused.

(2) The slewing bearing mounting base is expensive to manufacture.

In order to fix two sets of slewing bearings, two bases with welded structures are manufactured, and the combination of the slewing bearings and the mounting base is equivalent to the combination of the wheel rim and the connecting base. The base can be assembled and used after welding and forming and after annealing, machining and other processes, so that the manufacturing cost is high. In fact, the actual stresses on the bases holding their inner and outer races are also at a very low level, since the forces on the slewing bearings are very small.

(3) The materials of the inner ring and the outer ring of the slewing bearing are forged pieces, so that the cost is high.

If the steel with the same chemical composition is repeatedly forged after being cast and formed, the crystalline phase structure of the steel is more compact, and the mechanical property of the material is obviously improved. Therefore, the inner and outer rings of the general slewing bearing are made of forged parts. However, the blank size allowance of the forging is large, the machining and cutting workload is large, and therefore the manufacturing cost is high. Because the working load of the car slewing bearing is relatively small, if alloy steel forgings are still used for manufacturing the inner ring and the outer ring of the slewing bearing in the occasion, the car slewing bearing is too luxurious.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

As is known, among the supporting solutions for the car of large-scale sightseeing vehicles, the most mature and common one is the pivoting supporting solution of the encircling structure.

According to the scheme, a great deal of research is carried out on the structure and the operation principle of the large-scale sightseeing car, the conventional pivoting support scheme with a surrounding structure is abandoned, and a wheel type self-adaptive support system based on a wheel type system and with a pure mechanical structure is innovatively provided, so that the self-adaptive support of the sightseeing car can be realized, and the system is stable, reliable and low in cost.

Referring to fig. 1-3, there is shown an example of the structure of a large-scale sight-seeing car cab using a wheeled adaptive support system as given in this example.

As can be seen, the large-scale sightseeing bus 100 in the present example is only formed by the wheel type adaptive support system 110 and the car body 120 which are matched with each other in the composition structure.

The car body 120 is mounted by the wheel type adaptive support system 110, and the wheel type adaptive support system 110 forms adaptive support for the car body 120, so that the car body 120 can synchronously rotate adaptively based on the gravity of the car body 120 and the change of the gravity center when the horizontal state of the bottom surface 121 of the car body 120 changes under the condition of no external force, the horizontal state of the bottom surface 121 of the car body is synchronously adjusted, and efficient and reliable leveling is realized.

Accordingly, the wheel type adaptive support system 110 in the present example is mainly composed of the main wheel 111, the side wheels 112, and the rim 113 in cooperation with each other in the composition structure.

Wherein the rim 113 serves as the base member of the overall support system for supporting the car body 120 and for connecting external components (e.g., a sightseeing vehicle turntable). The rim 113 is a circular ring shape integrally fitted with the car body 120, and an inner side 113a thereof serves as a support guide surface, and is in rolling fit with the main wheel 111 to form a self-adaptive support for the car body 120.

In order to improve the reliability of the supporting and guiding, the present embodiment may be formed with corresponding supporting and guiding grooves on the inner side surface 113a of the rim 113, which are engaged with the main wheel 111 and distributed along the inner side surface of the rim 113.

In order to facilitate later assembly and matching with the main wheel 111, corresponding mounting openings are formed in the side wall of the supporting guide groove according to the distribution scheme of the main wheel 111.

Moreover, the side surfaces 113b on both sides of the rim 113 are used as limiting guide surfaces to be in rolling fit with the side wheels 112 to limit the axial movement of the car body 120, and can also limit the vertical swing of the car body 120 to ensure the stability of the running of the car body 120.

Also, in order to further enhance the limit guiding effect of the car body 120, the present embodiment may be formed with corresponding limit guide grooves on the side surfaces 113b of both sides of the rim 113, which are engaged with the side wheels 112 and distributed along the side surfaces of both sides of the rim 113.

In order to facilitate assembly and matching with the side wheels 112 in the later period, corresponding mounting openings can be formed in the side walls of the limiting guide grooves according to the distribution scheme of the side wheels 112.

With respect to the rim 113 described above, the main wheel 111 in the present wheel-type adaptive bearing system 110 is provided on the car body 120 with respect to the inner side of the rim, and the main wheel 111 is in rolling contact with the inner side of the rim to form adaptive bearing with respect to the car body 120, so that the car body 120 is supported integrally in the rim 113, and the car body 120 is able to rotate on its own axis with respect to the rim 113 based on the rolling contact of the main wheel 111.

In order to ensure the effect of adaptive support, the main wheels 111 in the wheel-type adaptive bearing system 110 in this embodiment are arranged in pairs, for example, two or more pairs of main wheels 111 can be arranged, and the pairs of main wheels 111 are symmetrically arranged on the car body 120 along the same circumference and are in contact rolling fit with the rim 113, so that the car body 120 can be supported in the rim 113 in a self-rotating manner. Preferably, the main wheels 111 support the car body 120 coaxially on the rim 113, that is, the car body 120 and the rim 113 are coaxially disposed, so that the reliability of the self-adaptive pivot leveling of the car body 12 with respect to the rim 113 is improved, and the horizontal state of the bottom surface 121 of the car body 120 can be adjusted synchronously by performing the self-adaptive pivot based on the gravity and the change of the center of gravity when the horizontal state of the bottom surface 121 of the car body 120 is changed without any external force.

The specific configuration of the main wheel 111 is not limited herein, and may be determined according to actual requirements. As long as the above functions can be achieved and stable reliability can be ensured.

Further, the side wheels 112 in the wheel-type adaptive support system 110 are arranged on the car body 120 relative to the side surfaces 113b of the rim, and meanwhile, the side wheels 112 are in rolling contact with and matched with the side surfaces 113b of the rim, so that limit guide is formed on the car body 120 in the axial direction, when the rotation effect of the car body 120 relative to the rim 113 is not influenced, limit is formed on the axial movement of the car body 120 relative to the rim 113, and meanwhile, limit can be formed on the vertical swing of the car body 120, so that the running stability of the car body 120 relative to the rim 113 is ensured.

In order to ensure the effect of the limit guide, the side wheels 112 in the one-set wheel-type adaptive support system 110 are arranged in pairs, for example, two or more pairs of side wheels 112 can be arranged, and the pairs of side wheels 112 are arranged on the car body 120 symmetrically along the same circumference and are in contact rolling fit with the side surface 113b of the rim, so that the car body 120 is stably limited in the rim 113.

Furthermore, according to the different number of the wheel-type adaptive support systems 110 configured in the large-scale tourist car 100, the paired side wheels 112 in each set of wheel-type adaptive support system 110 may be distributed on the same side of the rim 113, or may be distributed on both sides of the rim 113, which may be determined according to actual requirements.

In addition, when two or more wheel-type adaptive support systems 110 are provided in the large-scale tourist car 100, it is preferable that all the wheel-type adaptive support systems 110 are coaxially provided, and rims of the respective adaptive support systems are sequentially and fixedly connected to each other, so that the stability of the entire system and the structure of the large-scale tourist car can be improved. How to fixedly connect the rims can be determined according to actual requirements.

On the basis of the above scheme, the present embodiment may further include a corresponding servo motor and a gear transmission mechanism disposed in the car body 120, where the servo motor and the gear transmission mechanism constitute an auxiliary leveling scheme, and cooperate with the wheel-type adaptive support system 110, so as to precisely level the car body 120, ensure that the bottom surface 121 of the car body maintains a horizontal state in real time, and achieve efficient and reliable leveling. The matching scheme of the servo motor and the gear transmission mechanism is a common technology in the field, and is not described herein.

The large-scale sightseeing bus cage scheme based on the scheme has the advantages of simple overall structure and high reliability; the mechanism can effectively replace the scheme of the existing slewing bearing on the car, and compared with the scheme of the slewing bearing, the scheme can greatly reduce the manufacturing cost while achieving the same effect, shortens the manufacturing period, and is convenient to apply and can also be widely applied to the car of a small-sized sight-seeing bus.

The present solution is further illustrated below by a specific application example.

Referring to fig. 1-3, the car in the illustrated example is equipped with a 2-set wheeled adaptive support system 110. The wheeled system "embraces" the main structure of the car.

The rims 113 in the two wheel type self-adaptive supporting systems 110 are formed by bending steel plates, the tops of the two rims are welded by using the steel plates, the bottoms of the two rims are connected by using a steel pipe 115 (a cross bar 115 of a sightseeing vehicle turntable), the two rims are welded and connected by using the steel plates to form a connecting base with better rigidity, the end surface of the bottom of the connecting base is provided with a connecting flange 114 to be connected with the sightseeing vehicle turntable through bolts, and the whole rim and the sightseeing vehicle turntable form a whole after connection is completed, so that the structural rigidity of the whole rim is mutually enhanced.

Compared with the traditional lift car which usually adopts a combined structure of a slewing bearing and an installation base, the wheel rim and the connection base of the wheel type self-adaptive support system 110 are formed by welding and are mostly formed by bending and rolling steel plates, so that the purchase is easy, the processing is convenient, the manufacturing cost is low, and compared with the production and the manufacturing of the slewing bearing, the supply period is shortened. Because the rim 113 and the connecting base are welded into a whole, the integral rigidity of the rim is improved, and the rim is more stable when the sight-seeing bus runs normally.

Each set of wheeled adaptive support system 110 in this example consists of 2 main wheels 111 and 4 side wheels 112, i.e. a total of 4 main wheels and 8 side wheels in the overall system. The 4 main wheels support the car body 120 in the wheel rims 113 in a rotatable manner, and the 8 side wheels are oppositely distributed among the wheel rims 113 to limit the axial movement of the car body 120.

Therefore, during the operation of the sight-seeing bus, the main wheels 111 rotate automatically and concentrically along with the operation of the sight-seeing bus inside the rim 113 and have good tracking adaptability, 4 main wheels bear the load of the whole cage, each main wheel can bear about 2.5 tons of weight, the total load of the 4 main wheels is about 10 tons, and the load capacity is matched with the sum of the weight of the cage and passengers.

4 side wheels are arranged in the single-group wheel type system, and the side wheels are matched with the side surfaces of the wheel rims 113 in a rolling mode, so that the longitudinal sliding of the lift car can be effectively limited to help the servo driving mechanism to accurately position, the gear transmission central plane is kept in the same plane as much as possible, the leveling efficiency can be maximized, the gear transmission stress is balanced, and the reliability and the stability of the system are improved. When the car bears the front wind load, the side wheels mainly bear the acting force of the wind load. When passengers stand on the end faces of the lift cars, the lift cars are more or less inclined due to uneven stress on the two ends, and the side wheels can take the anti-overturning function of the whole lift cars under the working conditions.

The scheme of the large-scale sightseeing bus car is characterized in that when the scheme works: a main wheel and a side wheel in a wheel type system are equivalent to a slewing bearing inner ring, when a sight-seeing vehicle normally runs, a wheel rim changes in position and angle along with the rotation of the sight-seeing vehicle, a sensor monitors whether the ground in a car is horizontal or not, once an inclination angle is generated, a deviation model is immediately sent to a servo controller, the servo controller sends an action instruction to a servo motor, the servo motor drives a gear to transmit, the gear is connected with a car steel frame, the main wheel is fixed on the steel frame, so that the main wheel rolls on the inner side of the wheel rim, the change angle of the car is corrected, the ground in the car returns to a horizontal state, and the leveling effect is achieved.

As can be seen from the above example, the wheel type adaptive support scheme provided in this example has the following application advantages compared with the slewing support scheme:

(1) the raw materials are easy to purchase and process, the manufacturing period is shortened, and the manufacturing cost is reduced;

(2) the mounting base is omitted, and the existing structure is directly bolted with the rotary table of the sightseeing bus, so that the field mounting is facilitated;

(3) the bearing capacity is matched with the load, so that the bearing redundancy design is avoided, the self weight is reduced, and the manufacturing cost is also reduced;

(4) simple structure is convenient for install, does benefit to follow-up maintenance.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
