Description

Technical Field

[0001] The invention belongs to the technical field of underground parking garages, and in particular relates to an underground single-layer circulation parking garage used in old residential areas. Background Art

[0002] Most parking lots in China are self-propelled, which is far from meeting the demand for parking spaces due to the increase in the number of cars. The underground multi-story parking garage is characterized by high density and is the most advanced form of parking garage. This type of garage has a large capacity, with a large capacity of up to 1,000 to 3,000 parking spaces. It has the characteristics of fast oil shunting speed and high degree of automation, and is the best choice for major cities to solve the problem of parking difficulties.

[0003] The multi-story parking garage is an intelligent, three-dimensional logistics storage and transportation system that integrates automation technology, robotics technology, and computer technology. It can automatically and reliably complete the storage and retrieval of vehicles and the management of related information. The development and research of this system can solve the problem of parking difficulties in China and has great theoretical significance and practical value.

[0004] The main reason for the difficulty in parking in big cities at present is that there are too few parking places. Usually, we adapt to local conditions and use all feasible methods to increase the number of parking spaces, especially in residential areas, where parking lots should be built. Idle land on the roadside should be used as temporary parking lots, and underground garages should be built in relatively large places such as squares and green spaces in several adjacent communities. The first floor of residential buildings in the community should be renovated and built into garages to alleviate the problem of parking difficulties, and residents should be resettled or compensated. Multi-story parking garages can be built in the community.

[0005] The above-mentioned increase in the number of parking spaces on the ground will inevitably destroy the green environment in the community and affect the aesthetics of the community. There are certain difficulties in building a parking lot in the community. Usually, the community does not have vacant area for building a parking lot, and the idle land on the roadside is used as a temporary parking lot. It is difficult to find idle land around the community, and there are certain operational difficulties.

[0006] As mentioned above, underground garages are built in relatively large places such as squares and green spaces within several adjacent communities. The existing underground garages are usually large in area and take a long time to build, which affects the rest and daily life of the residents in the community.

[0007] The above-mentioned renovation of the first floor of the residential area into a garage will alleviate the parking problem. The renovation of the first floor requires a large cost and the available parking spaces are extremely limited.

[0008] The above-mentioned resettlement or compensation of residents is also costly and difficult to implement, and the available parking spaces are extremely limited. A multi-story parking garage can be built in the community. Large multi-story parking garages have high costs and long construction periods, while small multi-story parking garages are prone to accidents in the wind and rain, and require subsequent maintenance and repair, which is costly and unsafe.

[0009] In the existing technology of building underground parking garages in residential areas, underground multi-story parking garages are usually double-layer structures, which requires digging at least 5 meters below the ground foundation. However, since there are many underground pipelines in the residential area, there are certain difficulties in construction. At the same time, a depth of 5 meters requires a long construction period during the construction process, affecting the daily life of surrounding residents. Summary of the invention

[0043] The first force-bearing plate group 3-2 is composed of two parallel plates, and the distance between the plates is greater than the width of the thrust plate 2-5. The first force-bearing plate group 3-2, the second force-bearing plate group 3-3, the third force-bearing plate group 3-4 and the fourth force-bearing plate group 3-5 have the same structure. The first force-bearing plate group 3-2, the second force-bearing plate group 3-3, the third force-bearing plate group 3-4 and the fourth force-bearing plate group 3-5 are integrally formed with the vehicle carrier 3.

[0044] When the vehicle carrier 3 is above the first straight chain 2-1, the thrust piece 2-5 on the first straight chain 2-1 is located in the first force-bearing piece group 3-2, and when the vehicle carrier 3 moves to the end of the first transverse chain 2-3 under the action of the first straight chain 2-1, the first straight chain 2-1 stops working. At this time, the thrust piece 2-5 on the first transverse chain 2-3 is located in the third force-bearing piece group 3-4. The first transverse chain 2-3 runs under the action of the motor, and the thrust piece 2-5 on the first straight chain 2-1 is disengaged from the first force-bearing piece group 3-2, so that the vehicle carrier 3 is moved to the other end of the first transverse chain 2-3 under the action of the first transverse chain 2-3.

[0045] A guide device is provided under the support platform 1, and the guide device is used to adapt to the thrust plate 5 so that the thrust plate 5 has better stability during movement. The guide device can be a plurality of support gears 2-6, and the support gears 2-6 are arranged on the running paths of the first straight chain 2-1, the second straight chain 2-2, the first transverse chain 2-3 and the second transverse chain 2-4. The support gears 2-6 support the chains so that the thrust plates 2-5 on the chains are always against the first force-bearing plate group 3-2 or the second force-bearing plate group 3-3 or the third force-bearing plate group 3-4 or the fourth force-bearing plate group 3-5. A rotating shaft for the support gear 2-6 is provided on the support gear 2-6, and the rotating shaft is arranged on the support platform. The support gear 2-6 is a passive gear.

[0046] There is always only one vehicle carrier 3 on the first transverse chain 2-3 and the second transverse chain 2-4, so there is always a vacant position on the first transverse chain 2-3 and the second transverse chain 2-4, and the vacant position on the first transverse chain 2-3 and the second transverse chain 2-4 is arranged along the diagonal of the support platform 1.

[0047] The running track 1-1 includes a straight track 1-2 arranged along the length of the supporting plane and a transverse track 1-3 arranged along the width direction of the supporting plane.

The groove 3-7 is located at the center of the wheel body of the universal wheel 3-1, and the groove 3-7 is arranged around the wheel body of the universal wheel 3-1. The running track 1-1 is clamped on the groove 3-7. Under the action of the running track 1-1 and the groove 3-7, the vehicle carrier 3 moves along the direction of the running track 1-1.

The disc is embedded in the support platform 1, and the top of the disc is flush with the top of the support platform 1. The disc is provided with a track connected to the running track 1-1. The steering gear and the motor drive the rotation of the disc.

[0050] The universal wheel 3 - 1 is a vertical structure. During the steering process of the steering device 6 , the position of the universal wheel 3 - 1 does not change, thereby facilitating the rotation of the universal wheel 3 - 1 .

[0051] In the initial state, the track on the disc is connected to the straight track 1-2. When the vehicle carrier 3 moves to the steering device 6, the steering device and the motor drive the rotation of the disc.

The size of the through hole 4-1 is larger than the size of the top of the truncated cone 3-6, and the size of the through hole 4-1 is smaller than the size of the bottom of the truncated cone 3-6, so that there is a gap between the vehicle carrier 3 and the vehicle carrier plate 4.

[0053] The lifting device includes a lifting motor 5-1 and a lifting hook 5-2. The lifting hook 5-2 is located between the vehicle frame 3 and the vehicle plate 4.
