Technical Field

[0001] This utility model relates to the field of parking equipment technology, specifically to a tilting pit parking device. Background Technology

[0002] With the acceleration of urbanization and the continuous growth of car ownership, "parking difficulties" have become a common problem plaguing urban management. This is especially true in older residential areas and commercial centers where space is limited, resulting in a severe shortage of surface parking spaces. Multi-level parking garages are an effective solution, but traditional lift-and-slide and lane-stacking types have problems such as complex structures, high construction costs, and significant environmental impact.

[0003] Pit-type parking systems have gained attention in recent years as a solution for utilizing underground space. However, existing pit-type parking systems often require sufficient height, making them unsuitable for underground spaces with limited height.

[0004] Therefore, there is an urgent need for a parking system that can efficiently utilize underground space in low-ceilinged areas. Utility Model Content

[0005] The purpose of this invention is to provide a tilting pit parking device to solve the problem that existing parking devices are difficult to apply to low underground spaces.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3 This utility model provides a technical solution: a tilting pit parking device, in which two columns 1 are fixed at the rear end of the pit bottom. The columns are made of Q345 steel plates welded together, forming a cylindrical structure with a rectangular cross-section.

[0016] The upper platform 2 is rotatably connected to the inner side of the top of the column 1 via shafts on both rear ends. The lower platform 3 is parallel to the upper platform 2 and movably connected to the inner side of the column 1 on both rear ends. The rear end of the lower platform 3 can move freely relative to the column 1. For example, the rear ends of the lower platform 3 can be connected to the inner side of the column 1 via a rotating shaft and an oblong hole. The upper and lower platforms are made of patterned steel plates (8-10mm thick), with reinforcing ribs welded to the bottom to improve deformation resistance. Limiting steps are set at the front and rear ends. The top and bottom ends of the support beam 4 are rotatably connected to the two side walls near the front end of the upper platform 2 and the lower platform 3 via rotating shafts. That is, the support beam 4 plays a linkage role between the upper platform 2 and the lower platform 3. When the rear end of the upper platform 2 rotates relative to the column 1, the upper platform 2 drives the lower platform 3 to swing up and down synchronously through the support beam 4.

[0017] The base 6 is fixed to the bottom of the pit and is positioned at a position corresponding to the front sides of the lower platform 3.

[0018] The top of the hydraulic cylinder 5 is rotatably connected to the front side of the middle of both sides of the upper platform 2 via a rotating shaft, and the bottom end is fixed to the base 6.

[0019] The timing pulley set 8 is positioned laterally on the lower platform 3 corresponding to the rear side of the hydraulic cylinder 5. The timing pulley set 8 includes bearing seats 8.2 fixed to the two side walls of the lower platform 3 and shafts 8.1 rotatably sleeved on the bearing seats 8.2 near both ends. The timing sprocket 8.3 is fixedly sleeved on the end of the shaft 8.1.

[0020] The guide sprocket 9 is rotatably mounted on both sides of the lower platform 3, corresponding to the position on the front side of the column 1.

[0021] The bottom end of the chain 7 is connected to the base 6 located behind the cylinder 5. The chain 7 passes around the top of the synchronous sprocket 8.3 and the bottom of the guide sprocket 9 in sequence.

[0022] The connector 10 is fixed to the top of the front wall of the column 1. The connector 10 includes a connecting plate 10.1 fixed to the top of the front wall of the column 1, a guide sleeve 10.2 fixed to the front wall of the connecting plate 10.1, a guide rod 10.3 slidably sleeved in the guide sleeve 10.2, a lead screw 10.4 whose bottom end is fixedly connected to the top of the guide rod 10.3, a spring 10.5 sleeved outside the guide rod 10.3 and the lead screw 10.4 and whose bottom end is supported on the top surface of the guide sleeve 10.2, an adjusting nut 10.6 threadedly sleeved to the top of the lead screw 10.4, and a retainer 10.7 fixed to the bottom of the guide rod 10.3 and connected to the top of the chain 7.

[0023] In summary, the piston rod of the hydraulic cylinder 5 extends and pushes the upper platform 2 upward, causing the front ends of the upper platform 2 and the lower platform 3 to tilt upward simultaneously, so that the front end of the lower platform 3 is flush with the front edge of the pit, thus facilitating the entry and exit of vehicles on the lower platform 3.

[0024] The hydraulic cylinder 5 retracts the piston rod, pulling the upper platform 2 downwards, causing the front ends of both the upper platform 2 and the lower platform 3 to simultaneously tilt downwards, making the front end of the upper platform 2 flush with the front edge of the pit, so as to facilitate the entry and exit of vehicles on the upper platform 2.

[0025] When the vehicle is stopped on the upper or lower platform, it is in a stopped state, relying on the static friction between the tires and the top surface of the platform to keep the vehicle stationary in the tilted state.

[0026] When the hydraulic cylinders 5 extend and retract, the chain 7 moves simultaneously relative to the synchronous sprocket 8.3 and the guide sprocket 9. Since the synchronous sprockets 8.3 on both sides can rotate synchronously through the shaft 8.1, the lifting and swinging on both sides is effectively balanced, ensuring smooth movement. Among them, the chain 7 effectively supports the rear end of the lower platform 3 through the guide chain 9.

[0027] Rotating the adjusting nut 10.6 relative to the lead screw 10.4 can adjust the compression of the spring 10.5, thereby adjusting the tension of the chain 7 and the pitch angle of the upper and lower platforms.
