Description

Technical Field

[0001] This utility model relates to the field of motor vehicle storage technology, and more specifically to a pit-type multi-level simple lifting garage. Background Technology

[0002] With the advancement of technology and the widespread use of automobiles, the demand for parking spaces has grown rapidly, and traditional garages can no longer meet the demand. More and more residential communities, office buildings, and shopping malls are now adopting multi-level parking systems, which can store more vehicles in a limited space and have been widely promoted and developed.

[0003] Most existing two- or multi-story pit-type simple lifting mechanical garages use steel wire ropes or chains for direct lifting, which is time-consuming, labor-intensive, and has poor lifting efficiency. Utility Model Content

[0004] 1. The technical problem to be solved by the utility model:

[0005] To address the problems of time-consuming, labor-intensive, and inefficient lifting operations in existing pit-type vehicle parking garages, this utility model provides a simple multi-level lifting garage in a pit. It uses a pulley structure to lift and lower the multi-level vehicle-carrying inner frame within the pit, thereby reducing the force on the drive motor and simplifying the operation of storing and retrieving vehicles.

[0006] 2. Technical Solution:

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0008] A pit-type multi-level simple lifting garage includes an outer frame, an inner frame, and parking platforms. The parking platforms are arranged in multiple layers to carry motor vehicles. The multiple parking platforms are fixedly connected to the inner side of the inner frame. The outer frame is vertically inserted into the pit. The inner frame moves up and down inside the outer frame via a pulley structure, making operation labor-saving and efficient.

[0009] A further technical solution includes an outer frame comprising symmetrically square support columns installed at the bottom of the pit and two symmetrically transverse beams installed at the pit opening. The two beams are respectively connected above two pairs of symmetrical support columns, forming a front beam and a rear beam. The inner frame includes bases slidably connected to the inner sides of the corresponding support columns, with a support rod vertically fixed to each base. The parking platform is fixedly connected to the inner side of the support rod. A lifting sprocket is fixedly connected to the bottom of the base. The transverse pulley structure includes a lifting shaft, a lifting chain, a reduction motor, a transmission chain, a transmission sprocket, and a main shaft. The system consists of a drive sprocket and a lifting sprocket. The lifting shaft is rotatably connected to the front crossbeam, and the geared motor is fixedly connected below the front crossbeam. The output of the geared motor is connected to the drive sprocket of the shaft via a transmission chain. The drive sprocket is sleeved and fixed to the shaft body of the lifting shaft. Two transmission sprockets are installed near the two ends of the lifting shaft. One end of the lifting chain passes through the transmission sprocket and the two lifting sprockets in sequence, and is then fixedly connected to the rear crossbeam. The other end hangs down outside the transmission sprocket. The entire garage has a simple structure, is easy to install, and one geared motor can drive multiple parking spaces. It is low in cost and highly efficient.

[0010] Further technical solutions include a balance chain; a balance sprocket is also fixedly connected to the bottom of the base, one end of the balance chain passes around two balance sprockets in sequence and is fixedly connected to the rear crossbeam, and the other end hangs down on the outside of the balance sprocket, which plays the role of balancing the inner frame and preventing the inner frame from shaking when it is raised and lowered.

[0011] A further technical solution involves two pairs of four balancing chains symmetrically distributed on both outer sides of the inner frame along its length, with two chains in each pair arranged in a cross pattern to improve the balancing effect.

[0012] A further technical solution is that a fixed guide wheel is fixedly connected to the inner side of the upper part of the support column, and the support rod is rotatably connected to the fixed guide wheel; a lifting guide wheel is fixedly connected to the outer side of the base, and the inner frame is rotatably connected to the inner side of the support column through the fixed guide wheel and the lifting guide wheel, which plays a role in lifting and guiding and preventing deviation during lifting and lowering.

[0013] 3. Beneficial effects:

[0014] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0015] This utility model relates to a pit-type multi-level simple lifting garage with a moving pulley structure, which reduces the stress on the drive motor. The parking is concealed, with vehicles stored underground and no steel structure above ground, making it aesthetically pleasing and providing a wide field of vision. It occupies a small area, allowing multiple vehicles to be parked in one space, resulting in high space utilization. The structure is simple, installation is convenient, and one geared motor drives three parking spaces, making it inexpensive. Attached Figure Description

The two horizontal beams are respectively connected above the two pairs of symmetrical support columns 20, namely the front horizontal beam 16 and the rear horizontal beam 17. There are four support columns 20, which are symmetrically installed at the four corners of the square. The inner frame 2 includes bases 19 slidably connected to the inner side of the corresponding support columns 20. Each of the four bases 19 is vertically fixedly connected to a support rod 18. The parking plate 3 is fixedly connected to the inner side of the support rod 18. A lifting sprocket 21 is fixedly connected to the bottom of the base 19. The transverse pulley structure includes a lifting shaft 4, a lifting chain 6, a reduction motor 10, a transmission chain 11, a transmission sprocket 12, a shaft drive sprocket 14, and a lifting sprocket. 21; The lifting shaft 4 is rotatably connected to the front crossbeam 16, and can be rotatably connected via a bearing connected above the front crossbeam 16.

[0035] This embodiment of a pit-type multi-level simple lift parking garage has a three-level parking platform 3 structure, which can be connected to an existing control system. In actual use, the control system controls the reduction motor 10 to drive the lifting shaft 4 through the transmission chain 11. The lifting chains 6 at both ends of the shaft rise and fall synchronously. The three parking platforms 3 rise and fall on the inner side of the outer frame 1 under the transmission of the movable pulley structure. Fixed guide wheels 7 are on the outer frame 1, and lifting guide wheels 8 are on the inner frame 2, which serve as lifting guides. Four balance chains 5 are arranged on both sides of the length direction, cross-arranged, to balance the inner frame 2. When the inner frame 2 is lowered to the bottom, the first-level parking platform 3 is flush with the ground, and vehicles can be stored and retrieved at any time on the first level. When storing and retrieving vehicles on the first and second basement levels, the reduction motor 10 raises and lowers the parking platform 3 to the first-level position for vehicle storage and retrieval.
