Description

Circulation type double-layer bus parking garage

Field of the art

The invention relates to a parking facility, in particular to a circulating double-layer bus parking garage.

Background art

Along with the rapid development of the urban rail subways and the green buses in the large and medium China, the method brings great rapidness and convenience for the travel of citizens. Here, we communicate with the parking problem of buses, and because buses need to park and get out every trip every day, multiple bus parks are built in each city. The parking lot is carefully planned, the vehicles are stopped, an access passage is reserved, and the traditional conventional parking mode has a great problem that the occupied area of each vehicle is large, and the three-dimensional parking device of the buses is not seen at present, so that the possibility of reducing the occupied area is not considered.

(III) summary of the invention

The invention provides the circulating double-layer bus parking garage with the reinforced concrete bearing wall body, which aims to make up the defects of the original foundation bearing structure, so that the foundation bearing structure is simpler, firmer and more practical.

The invention is realized by the following technical scheme:

the utility model provides a double-deck bus parking storehouse of circulation formula, includes the parking space of upper and lower two-layer, its characterized in that: the model machine for the LZDG-1 bus test is manufactured four years ago, the basic structure form and the working principle of the model machine are completely the same as those of a ZL201510297388.0 internal circulation device, the basic structure form is completely changed, 30 buses and running equipment are enabled to be completely acted on a storehouse wall, and the storehouse wall also provides a reliable supporting foundation for 8 horizontal I-shaped tracks between chain wheels.

The model prototypes were used to describe the performance of the machine in terms of stationary and running states. Stationary state: the 16 parking suspension cables are sequentially and evenly arranged on the circulating chain link through the support hanging frame, and each suspension cable is 3.5 meters in width and 4 meters in height. The lifting cables 1 to 6 are positioned on the same horizontal line at the lower layer, the mutual distance between the lifting cables 6 is 0.5704 meters, wherein the front end of the lifting cable 1 is positioned at a vehicle outlet, and the rear end of the lifting cable 6 is positioned at a vehicle inlet; the 9 to 14 number 6 lifting cables are positioned on the same horizontal line of the upper layer, the 8 number 7 two lifting cables are vertically positioned between the upper layer and the lower layer at the right end, the 15 number 16 two lifting cables are vertically positioned between the upper layer and the lower layer at the left end, and the 4 lifting cables at the two ends are pulled by the supporting hanging brackets to enlarge the distance. Operating state: when the circulating chain links normally run, no matter clockwise or anticlockwise, we can intuitively find that the 16 lifting cables run in 180-degree rotation at the two ends except for normal synchronous running, and the phenomenon of gradually accelerating and gradually decelerating can be shown under the action of the supporting and hanging frame, so that the mutual distance between the lifting cables is enlarged, and the mutual non-scraping and non-touching of the lifting cables are ensured, namely the action of the supporting and hanging frame. The 0.5704 meter spacing facing the 3.5X4 meter hoist cable end surface can be said to provide a breakthrough in the cyclic operation.

Discarding the double portal frames of the LZDG-1 model test model machine, namely discarding the first letter L of the model, manufacturing the rest ZDGT model according to the ratio of 40:1, transferring the rest ZDGT model to reinforced concrete prefabricated walls of each row of storehouses, replacing the double portal frames by the prefabricated walls, replacing L by the Pinyin letter Y, and forming a new basic bearing structure by the prefabricated storehouses; in addition, the LZDG-1 type test prototype only has 16 parking suspension cables, each warehouse can be provided with about 30 parking suspension cables, a plurality of rows of warehouses are arranged in parallel and are called YZDG-2 type, the YZDG-2 type still keeps the end face of the suspension cable of 3.5X4 meters and the space of 0.5704 meters, and the running performance of the LZDG-1 type test prototype is completely consistent with that of the LZDG-1 type test prototype. The thickness of the reinforced concrete wall body of the parking garage is 0.6 meter, the wall body can be thickened or reduced according to the requirement, and the height of the wall body is 16.4 meters and the height of the LZDG-1 are completely consistent.

The more preferable scheme of the invention is as follows:

the three rows of parking storehouses are connected into a whole through two shared walls to form a unit, so that parking is more compact, a bus parking lot is formed by arranging 2 to 3 units, the three rows of parking storehouses not only can adapt to common foundation settlement, but also can leave a walking channel for a driver between adjacent units. Two ends of each two adjacent rows of parking storehouses are staggered for a distance in sequence, so that two ends of each multi-row parking storehouses are in a ladder shape, the shape is convenient for setting up a vehicle inlet and a vehicle outlet for each row of parking storehouses, and a vehicle inlet road and a vehicle outlet road are formed in a parking lot.

The buses are similar in weight and shape no matter being diesel vehicles, electric vehicles, diesel-electric hybrid vehicles or hydrogen fuel vehicles, and are very suitable for entering YZDG-2 type parking. However, the electric bus cannot be charged inside by inserting a large braid, and two options exist: (1) and drawing out the defective battery through the sliding rail, and pushing in the full battery. (2) And stopping charging at the charging pile. The YZDG-2 is also suitable for long vehicle types with two auxiliary wheels added to a double bridge, and is also suitable for double-layer buses; the car type of the three-bridge connecting shaft is not suitable because the length of the parking suspension cable is difficult to realize.

The distance between the lower opening of the vehicle inlet and the vehicle outlet and the end part of the bottom plate of the parking suspension cable is about one meter, the concrete prefabricated structure can be inwards extended to be 20cm away from the end part of the bottom plate of the parking suspension cable according to the width of the lower opening of the vehicle inlet and the width of the lower opening of the vehicle outlet, the distance of 20cm can also be realized through a steel structure, a short platform is formed, and guard rails are assembled on two sides of the short platform. Two U-shaped guide rails are respectively arranged on two sides of the front part of the short platform, the step lifting frame is guided to move up and down under the action of the two hydraulic cylinders, the step lifting frame is lifted to fill the gap of 20cm, the lower opening of the vehicle inlet and outlet is horizontally and seamlessly abutted with the short platform, the step lifting frame and the parking suspension cable bottom plate, and meanwhile, lifting and limiting are formed on the parking suspension cable bottom plate; the ladder lifting frame falls down, and the circulation operation device can start operation. The vehicle inlet and the vehicle outlet are as wide as the short platform, the short platform is slightly wider than the ladder lifting frame, the ladder lifting frame is slightly wider than the parking suspension cable bottom plate, four parking storehouses in each row of the structural form are arranged, two parking suspension cables at the vehicle inlet correspond to each other, and two parking suspension cables at the vehicle outlet correspond to each other.

If the perfect operation of the model prototype is a good horse, the prefabricated bearing warehouse is a good saddle; if the environment-friendly and comfortable bus is a good horse, the YZDG-2 is a good saddle.
