Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional garages, in particular to a back-to-back two-layer lifting device. Background Art

[0002] The currently used back-to-back three-dimensional garage is arranged and installed by arranging two garage frames back to back. Since a certain distance needs to be left between the opposite rear crossbeams of the two garage frames to accommodate and operate corresponding power equipment such as motors, the occupied space is large and the consumables are many. In some basements with limited space, the distance between the two rows of rear crossbeams will further squeeze the parking space, making it inconvenient for vehicles to park. In addition, the existing back-to-back garages are mostly lifting and traversing three-dimensional garages, and at least two parking space positions are required horizontally, and one empty space needs to be left to enable the lower parking space to move horizontally, so as to facilitate the lifting and taking of the upper parking space. It cannot be arranged on a small plot of land, and the utilization rate of the parking space is low. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a two-layer lifting device that improves the space utilization rate, reduces the occupied site area and cost.

[0004] The utility model is realized by the following technical solutions. A back-to-back two-layer lifting device includes a garage frame, a car-carrying platform, and a lifting mechanism for driving the car-carrying platform to lift. The garage frame is provided with a first parking area and a second parking area distributed left and right. Both the first parking area and the second parking area are provided with a car-carrying platform and a lifting mechanism, and pits are provided on the ground directly below the car-carrying platform in both the first parking area and the second parking area; the car-carrying platform includes an upper car-carrying board and a lower car-carrying board distributed up and down. The size of the pit is adapted to the size of the lower car-carrying board, and the depth of the pit is not less than the distance between the upper car-carrying board and the lower car-carrying board; the lifting mechanism drives the upper car-carrying board and the lower car-carrying board to lift synchronously.

[0005] This solution divides the garage frame into two parking areas. Vehicles can be parked on the car-carrying platform in each parking area. The car-carrying platform is provided with two layers of car-carrying boards, so that four vehicles can be parked in one garage frame, increasing the number of parked vehicles. By setting pits in the parking areas, the lower car-carrying board can be lowered into the pit when taking and placing vehicles, thus facilitating the taking and placing of vehicles on the upper car-carrying board, making reasonable use of the underground space and improving the space utilization rate. Compared with the existing lifting and traversing three-dimensional garage, there is no need to set a horizontal empty space to traverse the vehicle, shortening the horizontal dimension of the garage frame. By using the underground space, all the space in the garage frame can be utilized, also improving the space utilization rate within the frame, reducing the floor area of the garage, and improving the applicability.

[0006] As an optimization, a rubber base is fixedly arranged at the bottom of the pit, and a rubber pad opposite to the rubber base is fixedly arranged at the bottom of the unloading vehicle plate. In this optimization scheme, the unloading vehicle plate has a shock-absorbing effect when it is lowered into the pit and lands, so that the unloading vehicle plate lands more stably.

[0007] As an optimization, a limiting groove is provided on the top of the rubber base, and a limiting convex block is provided on the bottom of the rubber pad to fit in the limiting groove. When the unloading platform of this optimization solution is lowered to the pit, the limiting convex block is engaged in the limiting groove to prevent the unloading platform from shifting and shaking, making the unloading platform more stable.

[0008] As an optimization, the size of the loading plate is larger than the size of the pit. In this optimization scheme, the size of the loading plate is larger than the size of the pit, so the loading plate can be set up on the pit, making the parking of the loading plate more stable.

[0009] As an optimization, the downloading vehicle plate is slidably connected to the pit in the vertical direction. This optimization solution can prevent the downloading vehicle plate from shaking in the horizontal direction when it is lifted up and down in the pit, making the lifting of the downloading vehicle plate more stable.

[0010] As an optimization, the garage frame includes a left crossbeam, a middle crossbeam and a right crossbeam arranged in sequence from left to right, the left crossbeam and the right crossbeam are fixedly connected to a longitudinal beam between the middle crossbeam, and the bottoms of the left crossbeam, the middle crossbeam and the right crossbeam are fixedly connected to support columns, the first parking area is formed between the left crossbeam and the middle crossbeam, and the second parking area is formed between the right crossbeam and the middle crossbeam. In this optimization scheme, the left and right crossbeams of the garage frame are connected to the same middle crossbeam to form a back-to-back structure. Compared with the existing back-to-back stereo garage, the two crossbeams in the middle of the existing back-to-back stereo garage are optimized to only one middle crossbeam with a support column, which saves materials and reduces costs. At the same time, the distance between the two crossbeams is eliminated, which further reduces the floor area and improves space utilization.

[0011] As an optimization, the loading plate is slidably connected to the support column in the vertical direction. This optimization solution can prevent the loading plate from shaking in the horizontal direction when it is lifted up and down, making the lifting of the loading plate more stable.

[0012] As an optimization, the driving motor and transmission shaft of the lifting mechanism in the first parking area are placed on the left crossbeam, and the driving motor and transmission shaft of the lifting mechanism in the second parking area are placed on the right crossbeam. This optimization solution solves the problem in the prior art that it is inconvenient to install the lifting mechanism after the two middle crossbeams are optimized into one crossbeam. The two lifting mechanisms are respectively installed on the left crossbeam and the right crossbeam, which has a reasonable structure and is more convenient to install.

[0013] The beneficial effects of the present utility model are as follows: A same intermediate crossbeam is connected between the left crossbeam and the right crossbeam of the garage frame to form a back-to-back structure. Compared with the existing back-to-back type stereo garage, the two crossbeams in the middle of the existing back-to-back type stereo garage are optimized to be only one intermediate crossbeam cooperating with the support columns, saving materials and reducing costs. At the same time, the distance between the two crossbeams is also eliminated, further reducing the floor area and improving the space utilization rate.

[0014] The garage frame is divided into two parking areas. In each parking area, the vehicle-carrying platform can park vehicles. The vehicle-carrying platform is provided with two layers of vehicle-carrying plates. In this way, four vehicles can be parked in one garage frame, increasing the number of parked vehicles. By setting a pit in the parking area, when taking or placing a vehicle, the lower vehicle-carrying plate can be lowered into the pit, thus facilitating the taking and placing of vehicles on the upper vehicle-carrying plate, rationally utilizing the underground space and improving the space utilization rate. Compared with the existing lifting and traversing type stereo garage, there is no need to set a lateral empty space for traversing the vehicle, shortening the lateral dimension of the garage frame. By utilizing the underground space, all the space within the garage frame can be utilized, also improving the space utilization rate within the frame, reducing the floor area of the garage and enhancing the applicability.

[0015] The pit and the lower vehicle-carrying plate are in contact through a rubber base and rubber pads, having a shock-absorbing effect, making the lower vehicle-carrying plate more stable when landing. Moreover, the lower vehicle-carrying plate is slidably connected to the pit, and the upper vehicle-carrying plate is slidably connected to the support column, making the lifting more stable and having higher safety.

[0026] In this embodiment, two support columns 4 are fixedly connected to both ends of the bottoms of the left crossbeam 1, the right crossbeam 3, and the middle crossbeam 2. The support columns 4 are fixedly installed on the ground. Two longitudinal beams 5 are fixedly connected between the left crossbeam 1 and the middle crossbeam 2, and two longitudinal beams 5 are also fixedly connected between the right crossbeam 3 and the middle crossbeam 2.

[0027] Both the first parking area and the second parking area are provided with a car-carrying platform and a lifting mechanism 13. Pits 8 are provided on the ground directly below the car-carrying platforms in both the first parking area and the second parking area.

[0028] The car-carrying platform includes an upper car-carrying board 6 and a lower car-carrying board 7 distributed up and down. In this embodiment, the upper car-carrying board 6 and the lower car-carrying board 7 are connected by multiple first steel wire ropes 11. The upper ends of the first steel wire ropes 11 are fixedly connected to the bottom of the upper car-carrying board 6, and the lower ends of the first steel wire ropes 11 are fixedly connected to the top of the lower car-carrying board 7.

[0029] The size of the pit 8 is adapted to the size of the lower car-carrying board 7, and the size of the upper car-carrying board 6 is larger than the size of the pit 8. The sizes of the pit, the lower car-carrying board, and the upper car-carrying board refer to the length and width dimensions. The depth of the pit 8 is not less than the distance between the upper car-carrying board 6 and the lower car-carrying board 7.

[0030] The lifting mechanism 13 drives the upper loading vehicle board 6 and the lower loading vehicle board 7 to lift and lower synchronously. The lower loading vehicle board 7 is slidably connected to the pit 8 in the vertical direction, and the upper loading vehicle board 6 is slidably connected to the support column 4 in the vertical direction.

[0031] Specifically, vertical first sliding grooves 81 extending in the vertical direction are formed on the front and rear side walls of the pit 8. First sliding blocks 71 slidably connected to the first sliding grooves 81 are fixedly connected to the outer walls of the front and rear sides of the lower loading vehicle board 7. The lower loading vehicle board 7 is slidably connected to the first sliding grooves 81 of the pit 8 through the first sliding blocks 71, and the lower loading vehicle board is driven by the lifting mechanism to move up and down along the first sliding grooves.

[0032] For the two support columns 4 at the bottoms of the left cross beam 1 and the right cross beam 3, a vertically extending second sliding groove 41 is formed on each of the opposite side walls. For the two support columns 4 at the bottom of the middle cross beam 2, two vertically extending second sliding grooves 41 are formed on each of the opposite side walls. Two second sliding blocks 61 are fixedly connected to the front and rear side walls of the upper loading vehicle board 6.

[0033] The lifting mechanism 13 includes a driving motor 131, a transmission shaft 132, and a second steel wire rope 12. The driving motor 131 and the transmission shaft 132 of the lifting mechanism 13 in the first parking area are placed on the left cross beam 1, and the driving motor 131 and the transmission shaft 132 of the lifting mechanism 13 in the second parking area are placed on the right cross beam 3.

[0034] Specifically, the driving motor 131 is a double-shaft motor, and the driving motor 131 is fixedly arranged in the middle of the cross beam. Output shafts at both ends of the double-shaft motor are fixedly connected to the transmission shafts 132, and the two transmission shafts 132 are rotatably installed on the cross beam. Two rope winding grooves are formed at the ends of the two transmission shafts 132, and the second steel wire rope 12 is wound around each of the two rope winding grooves. Two pulleys 14 are installed on the longitudinal beam 5, and the two sliding seats 14 are arranged left and right. The two second steel wire ropes 12 on the transmission shaft 132 correspond to the two pulleys 14 one by one, and the two second steel wire ropes 12 respectively bypass the two pulleys 14 and are fixedly connected to the upper loading vehicle board 6.

[0035] A rubber base 9 is fixedly installed at the bottom of the pit 8 in this embodiment, and a rubber cushion block 10 opposite to the rubber base 9 is fixedly connected to the bottom of the downloading vehicle board 7. A limiting groove 91 is provided at the top of the rubber base 9, and a limiting convex block 101 that is snap-fitted with the limiting groove 91 is provided at the bottom of the rubber cushion block 10.

[0036] Working principle: When taking out the vehicle on the uploading vehicle board 6, the driving motor 131 is used to drive the transmission shaft 132 to rotate, so as to release the second steel wire rope 12. The uploading vehicle board 6 and the downloading vehicle board 7 slide downward under their own weights. The downloading vehicle board 7 descends into the pit 8, and the uploading vehicle board 6 stops on the ground to take out the vehicle. When it is necessary to park the vehicle on the uploading vehicle board 6, the driving motor 13 rotates in the reverse direction to drive the uploading vehicle board 6 and the downloading vehicle board 7 to rise.
