Description

Technical Field

[0001] This utility model relates to a three-dimensional parking device, and more particularly to a split-type mobile three-dimensional parking device suitable for cantilever beam parking platforms. Background Technology

[0002] Most current multi-level parking platforms are four-corner supported single-level platforms. These platforms have high construction costs and occupy a large space. Their corresponding multi-level parking devices are equipped with clamping, lifting, lateral movement and steering mechanisms, which are not only more complex in structure, but also have more transmission components and higher costs. The newly emerging cantilever beam parking platform has the advantages of occupying less space and having lower construction costs, but it is not suitable for existing multi-level parking devices. Summary of the Invention

[0003] The purpose of this utility model is to address the above-mentioned shortcomings of the existing technology by providing a split-type mobile three-dimensional parking device. It is not only simple in structure, low in cost, and reliable, but also has high operating efficiency and wide application range, and can be applied to cantilever beam parking platforms.

[0004] To achieve the above objectives, this utility model provides a split-type mobile three-dimensional parking device, comprising two parking units. Each parking unit includes two sets of front and rear columns located on opposite sides. The front and rear columns of the same set are connected by a lower and upper crossbeam. The device is characterized in that: a steering wheel is connected to the lower end of each front and rear column; a movable column is provided on the opposite side of each front and rear column of the same set via a longitudinal guide rail pair; the two movable columns are fixedly connected by a movable crossbeam, which is fixedly connected to a push rod; and a lifting element is fixedly connected to the lower crossbeam. The moving rod of the lifting element is fixedly connected to the push rod above it. The push rod and the upper crossbeam on the same side are connected to their respective housings through a longitudinal traction connection mechanism. Each housing is equipped with a geared motor and has a horizontal transmission shaft and two longitudinal rotating shafts through bearings. The geared motor is connected to the transmission shaft through a transmission mechanism. The transmission shaft has two worm gears with opposite directions of rotation. The two rotating shafts are fixedly connected to worm wheels that mesh with their respective worm gears. The lower end of each rotating shaft is fixedly connected to a retaining arm. Two adjacent moving columns on both sides are fixedly connected through two transverse connecting rods.

[0005] The aforementioned lifting element can be an electric push rod, and its moving rod is a lead screw; the lead screw drives the push rod and the moving crossbeam to rise and fall.

[0006] The aforementioned lifting element can also be a hydraulic cylinder, with its moving rod being a piston rod; the piston rod drives the push rod and the moving crossbeam to rise and fall.

[0007] The aforementioned longitudinal traction connection mechanism can be two pulleys connected to the push rod and two traction belts wrapped around their respective pulleys in the middle. The two ends of the traction belts are respectively fixed to the upper crossbeam and the box body. When the push rod and the moving crossbeam are raised and lowered, the traction belts can drive the box body to be raised and lowered.

[0008] The aforementioned longitudinal traction connection mechanism can also consist of two sprockets connected to the push rod and two chains wound around their respective sprockets in the middle, with the two ends of the chains fixedly connected to the upper crossbeam and the box body respectively; when the push rod and the moving crossbeam are raised and lowered, the chains can drive the box body to be raised and lowered.

[0009] The aforementioned transmission mechanism can be a sprocket and chain mechanism or a belt and pulley mechanism;

[0010] This utility model presents two parking devices corresponding to the two front wheels and two rear wheels of a vehicle, respectively. Each parking device, through a reduction motor, transmission mechanism, worm gear, and meshing worm wheel on two housings, enables two sets of clamping arms to grip the two front wheels or two rear wheels. The lifting element drives the push rod and moving crossbeam to rise, while the longitudinal traction connecting mechanism simultaneously moves the housing upwards, thus lifting the vehicle. Each steering wheel can move the two parking devices to place the vehicle on the cantilever beam parking platform. Afterwards, each set of clamping arms releases the two front wheels and two rear wheels, completing the three-dimensional parking. The vehicle can be retrieved three-dimensionally by reversing the action. Since the lifting distance of the housing is twice that of the lifting distance of the push rod and moving crossbeam on the same side, its operating efficiency is high. In addition, it does not require a steering mechanism, so its structure is relatively simple and low in cost. The worm gear and worm wheel have a self-locking function, which can ensure the reliability of gripping the wheels. The two parking devices are separate, and their spacing can be adjusted arbitrarily, making them suitable for cars with different wheelbases and with a wide range of applications.

[0011] As a further improvement of this utility model, the two transverse connecting rods are fixedly connected by several lateral connecting rods, which can improve the load-bearing strength of the device;

[0012] As a further improvement of this utility model, each of the arm arms is provided with a support base fixedly connected to the box body below it; the support base can improve the support strength of the arm arms clamping the tire.

[0013] In summary, this utility model not only has a simple structure, low cost, and good reliability, but also high operating efficiency and wide range of applications, and can be applied to cantilever beam parking platforms. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] like Figures 1 to 8 As shown, the split-type mobile three-dimensional parking device of this embodiment includes two sets of parking devices 1. Each set of parking devices 1 includes two sets of front columns 2 and rear columns 3 located on opposite sides. The front columns 2 and rear columns 3 are both channel steel structures. The front columns and rear columns in the same set are connected by a lower crossbeam 4 and an upper crossbeam 5. The lower ends of the front columns 2 and rear columns 3 are connected to steering wheels 6. The opposite side of the front columns 2 and rear columns 3 in the same set is provided with a movable column 8 through a longitudinal guide rail pair 7. The two movable columns 8 are welded and fixedly connected by a movable crossbeam 9. A push rod 12 is fixedly connected below the movable crossbeam 9. An electric push rod 10, which serves as a lifting element, is fixedly connected to the lower crossbeam 4. Its lead screw 11 is fixedly connected to the push rod 12 above it. The movable crossbeam 9 and the upper crossbeam 5 on the same side are connected to their respective housings 15 through a longitudinal traction connection mechanism. The longitudinal traction connection mechanism includes two pulleys 13 connected to the push rod 12 and two traction belts 14 wrapped around the pulleys 13 in the middle. Figure 2 (On one side, only pulleys are shown, not the traction belt.) The traction belts 14 are all made of steel. The two ends of the traction belts 14 are fixedly connected to the upper crossbeam 5 and the box body 15, respectively. Inside the box body 15, a reduction motor 17 is fixedly mounted on a bracket 16 and a horizontal transmission shaft 18 and two longitudinal rotating shafts 19 are mounted on a bearing. The reduction motor 17 is connected to the transmission shaft 18 through a sprocket and chain mechanism 20. The transmission shaft 18 is provided with two worm gears 21 with opposite directions of rotation. The two rotating shafts 19 are fixedly connected with worm wheels 22 that mesh with their respective worm gears. The lower end of each rotating shaft 19 is fixedly connected with a retaining arm 23. Below each retaining arm 23, there is a support seat 24 fixedly connected to the box body 15. The two adjacent movable columns 8 on both sides are fixedly connected by two transverse connecting rods 25. The two transverse connecting rods 25 are fixedly connected by several lateral connecting rods 26.

[0024] The two parking devices 1 of this utility model correspond to the two front wheels and two rear wheels of a vehicle, respectively. The parking devices can be moved in any direction via four steering wheels 6. The two parking devices 1 are connected by a reduction motor 17, a sprocket and chain mechanism 20, a drive shaft 18, a worm gear 21 and a meshing worm wheel 22, and two rotating shafts 19 on their two housings 15. This causes two sets of clamping arms 23 to clamp the two front wheels or the two rear wheels. The electric push rod 10 drives the push rod 12, the moving crossbeam 9 and the two moving columns 8 to rise. When the push rod 12 moves upward, the two pulleys 13 connected to it drive the housing 15 to move upward simultaneously via two traction belts 14, thereby lifting the vehicle. The movement of the two parking devices can then be completed by the steering wheels 6. The vehicle is placed on the cantilever beam parking platform, and then each set of clamping arms 23 releases the two front wheels and two rear wheels to complete the three-dimensional parking. The vehicle can be retrieved in three dimensions by reversing the action. Since one end of the traction belt 14 is fixed to the upper crossbeam 5, the lifting distance of the box 14 driven by one end is twice the lifting distance of the push rod 12 and the two columns 8. Its operation efficiency is high, which can reduce the stroke of the electric push rod 10 and the columns 8. In addition, there is no need for a steering mechanism, so its structure is relatively simple and low cost. The worm gear 21 and the worm wheel 22 have a self-locking function, which can ensure the reliability of clamping the wheels. The two sets of parking devices 1 are split type, and their spacing can be adjusted arbitrarily. They can be used for cars with different wheelbases and have a wide range of applications.

[0025] The two movable columns 8 on both sides, the two horizontal connecting rods 25 and several lateral connecting rods 26 are fixed together to form a frame structure, which can improve the load-bearing strength of the device; the support base 24 improves the support strength of the clamping arm clamping the tire.

[0026] This utility model is not limited to the above-described embodiments. For example, the above-described lifting element can also be replaced with a hydraulic cylinder, whose moving rod is a piston rod; the piston rod drives the push rod to rise and fall; the above-described longitudinal traction connection mechanism can also be replaced with two sprockets fixed to the moving crossbeam and two chains wrapped around their respective sprockets in the middle, with the two ends of the chains fixed to the upper crossbeam and the box body respectively; when the push rod and the moving crossbeam rise and fall, the chain can drive the box body to rise and fall; the sprocket and chain mechanism can also be replaced with a belt pulley mechanism; all of the above fall within the protection scope of this patent.
