Description

TECHNICAL FIELD

[0001] The utility model relates to an arc track lifting type parking equipment capable of improving the balance stability of the vehicle loading plate. BACKGROUND

[0002] With the sharp rise of the automobile ownership, the parking difficulty problem is increasingly prominent, especially in the population dense areas such as large-scale shopping malls, residential areas and government units, the simple ground natural parking has been unable to meet the parking demand.

[0003] Therefore, the Chinese patent with the application number 202011143149.7 provides a non-avoiding type three-dimensional parking equipment, mainly including U-shaped base channel steel 101, U-shaped beam channel steel 103, C-shaped driving connecting rod 102, driven chain rod 104, oil cylinder 5, vehicle loading plate and other components, the U-shaped base channel steel 101 is fixed on the ground, the two ends of the C-shaped driving connecting rod 102 are rotatably connected with the U-shaped base channel steel 101 and the U-shaped beam channel steel 103 respectively, and the two ends of the driven chain rod 104 are rotatably connected with the U-shaped base channel steel 101 and the U-shaped beam channel steel 103 respectively. The distance between the connecting points at the two ends of the C-shaped driving connecting rod 102 is equal to the distance between the connecting points at the two ends of the driven chain rod 104, and the distance between the two connecting points on the U-shaped base channel steel 101, which are rotatably connected with the C-shaped driving connecting rod 102 and the driven chain rod 104, is equal to the distance between the two connecting points on the U-shaped beam channel steel 103, which are rotatably connected with the C-shaped driving connecting rod 102 and the driven chain rod 104, that is, the U-shaped base channel steel 101, the U-shaped beam channel steel 103, the C-shaped driving connecting rod 102 and the driven chain rod 104 form a parallelogram mechanism. The vehicle loading plate is fixed on the U-shaped beam channel steel and used for parking vehicles. The oil cylinder is connected with the C-shaped driving connecting rod and the U-shaped base channel steel, and provides power to drive the C-shaped driving connecting rod to rotate through the oil cylinder, so as to realize the upward rising and forward ground parking action of the U-shaped beam channel steel and the vehicle loading plate thereon.

[0004] However, it is found in actual use that the above-mentioned three-dimensional parking equipment is unstable, and the specific situation is as follows:

[0005] As shown in Figure 8 When the vehicle loading plate (the vehicle loading plate is hidden in Figure 8 ) is parked on the ground along with the U-shaped beam channel steel 103, the straight line where the two connecting points on the U-shaped base channel steel 101, which are rotatably connected with the C-shaped driving connecting rod 102 and the driven chain rod 104, are located is almost on the same line as the straight line where the two connecting points on the U-shaped beam channel steel 103, which are rotatably connected with the C-shaped driving connecting rod 102 and the driven chain rod 104, are located (as shown in Figure 8When the distance between the second connecting point and the fourth connecting point is greater than the distance between the first connecting point and the third connecting point, the state of the mechanism is no longer a true parallelogram (as indicated by the dotted line), which will result in that when the oil cylinder 5 drives the C-shaped driving link 102 to pull up the U-shaped beam channel steel 103 and the vehicle loading plate thereon along an arc trajectory, the part of the U-shaped beam channel steel 103 connected with the C-shaped driving link 102 will be first lifted up, so that the U-shaped beam channel steel 103 is inclined, and the straight line where the two connecting points of the C-shaped driving link 102 and the driven chain link 104 on the U-shaped beam channel steel 103 are located will become an inclined line, and when the included angle between the inclined line and the straight line where the two connecting points of the driven chain link 104 are located reaches a certain angle, the part of the U-shaped beam channel steel 103 connected with the driven chain link 104 will be lifted up. When the oil cylinder 5 drives the C-shaped driving link 102 to rotate forward to lower the U-shaped beam channel steel 103 and the vehicle loading plate thereon to almost the ground, the part of the U-shaped beam channel steel 103 connected with the driven chain link 104 will be first lowered to the position, and the U-shaped beam channel steel 103 is also inclined. It can be seen that the above-mentioned three-dimensional parking equipment will be inclined at the initial stage of the vehicle loading plate rising and the end stage of the vehicle loading plate lowering, which will pose a safety threat to the vehicle parked on the vehicle loading plate.

[0031] Embodiment:

[0032] As Figures 1 to 6 The utility model discloses an arc track lifting type parking equipment capable of improving the balance stability of the vehicle carrying plate, which comprises a vehicle carrying plate 6 and parallelogram mechanisms symmetrically arranged on both sides, and the parallelogram mechanism comprises a groove base 1, a groove beam 4, a driving rod 2, a elbow support rod 3 and an oil cylinder 5 (wherein the functions of the groove base 1, the groove beam 4, the driving rod 2 and the elbow support rod 3 are equivalent to the U-shaped base channel steel 101, the U-shaped beam channel steel 103, the C-shaped driving connecting rod 102 and the driven chain rod 104 mentioned in the background art).

[0033] The groove base 1 is a channel steel, which is horizontally fixed on the ground for installation, and the groove base 1 between the two sides is used for parking the vehicle on the bottom layer. The groove beam 4 is provided with two high parts, which are a rectangular part 4.1 and a trapezoidal part 4.2 respectively.

[0034] As Figure 4 The driving rod 2 of the utility model comprises a long straight rod part 2.2 and a short straight rod part 2.1 connected into one body, and the long straight rod part 2.2 and the short straight rod part 2.1 have an included angle, so that the driving rod 2 as a whole has a "7" shape. The end of the short straight rod part 2.1 is rotationally connected with the groove base 1 at a first connecting point 7, and the end of the long straight rod part 2.2 is rotationally connected with the groove beam 4 at a second connecting point 8, and the second connecting point 8 is located on the rectangular part 4.1 of the groove beam 4.

[0035] As Figure 6As shown, one end of the elbow support rod 3 is bent, and the bent end is provided with an inclined part 3.1 and a horizontal part 3.2. The two ends of the inclined part 3.1 form corner points 3.3, respectively. The horizontal part 3.2 of the elbow support rod 3 is rotationally connected with the groove beam 4 at the fourth connecting point 10, which is located on the trapezoidal part 4.2. The bent end of the elbow support rod 3 can better match the shape of the trapezoidal part 4.2, so as to avoid the collision between the elbow support rod 3 and the groove beam 4 during the rising and falling process. The other end of the elbow support rod 3 is rotationally connected with the groove base 1 at the third connecting point 9.

[0036] In addition, the distance between the first connecting point 7 and the second connecting point 8 is equal to the distance between the third connecting point 9 and the fourth connecting point 10, and the distance between the first connecting point 7 and the third connecting point 9 is equal to the distance between the second connecting point 8 and the fourth connecting point 10, that is, the groove base 1, the groove beam 4, the driving rod 2 and the elbow support rod 3 form a parallelogram. The rotation connection at the connecting point can be achieved by connecting the pin shaft.

[0037] As shown in Figure 2 and Figure 3 As shown, the second connecting point 8 and the fourth connecting point 10 are respectively arranged at the two high positions of the rectangular part 4.1 and the trapezoidal part 4.2 on the groove beam 4, so that when the groove beam 4 is parked on the ground, the horizontal position where the second connecting point 8 and the fourth connecting point 10 are located is higher than the horizontal position where the first connecting point 7 and the third connecting point 9 are located, and the straight line where the second connecting point 8 and the fourth connecting point 10 are located has an angle with the straight line where the third connecting point 9 and the fourth connecting point 10 are located. The angle is referred to as the tension angle A, and the tension angle A adopted in the embodiment is 10 degrees. The formed tension angle A will have an angle of inclination to the groove beam 4 in the initial stage of rising and the end stage of falling (the initial stage of rising is the stage of starting to pull up the groove beam parked on the ground and the vehicle plate thereon, and the end stage of falling is the stage when the groove beam and the vehicle plate thereon are almost parked on the ground during the falling process), so as to reduce the inclination of the vehicle plate 6 in the initial stage of rising and the end stage of falling, and to make the balance stability of the vehicle plate 6 higher, and to better ensure the safety of parking.

[0038] The greater the pull angle A, the more stable the loading plate 6 will be in the initial stage of lifting and the end stage of lowering. Of course, due to the influence of other structures, the pull angle A cannot be made infinitely large. For example, making the pull angle A larger means that the second connecting point 8 on the channel beam 4 needs to be raised, and the raising of the second connecting point 8 will cause the first connecting point 7 on the channel base 1 to also be raised, which will cause the oil cylinder 5 to block the first layer of trolley from opening the door after the loading plate 6 is lifted into place. Secondly, if you don't want to raise the height of the first connecting point 7, you can also raise the height of the fourth connecting point 10, but this will cause the chassis of the trolley to collide with the raised part of the channel beam 4, so the design of the pull angle should consider the influence of multiple factors.

[0039] The main body of the oil cylinder 5 of the embodiment is rotationally connected with the channel base 1, and the end of the piston rod of the oil cylinder 5 is rotationally connected with the bending position between the long straight rod part 2.2 and the short straight rod part 2.1. The position where the main body of the oil cylinder 5 is rotationally connected with the channel base 1 is between the first connecting point 7 and the third connecting point 9. The oil cylinder 5 provides power for the rotation of the driving rod 2, and in turn drives the operation of the entire parallelogram mechanism.

[0040] The rectangular part 4.1 of the embodiment is located at one end of the channel beam 4, the trapezoidal part 4.2 is located in the middle of the channel beam 4, and the rectangular part 4.1 and the trapezoidal part 4.2 form an installation plane 4.3 for supporting the loading plate 6. The channel beam 4 has two side walls, and the driving rod 2 and the elbow support rod 3 are accommodated between the two side walls of the channel beam 4.

[0041] The loading plate of the embodiment is provided with two plates 6, which are respectively fixedly installed on the installation plane 4.3 of the channel beam 4 and are lifted together with the channel beam 4. The loading plate 6 is used to support the parked vehicle.

[0042] In addition, by connecting the trapezoidal part 4.2 with the elbow support rod 3, the height of the fourth connecting point 10 is increased, and the part of the elbow support rod 3 extending into the channel beam 4 is increased, thereby improving the stability of the elbow support rod 3 relative to the channel beam 4 when moving.

[0043] The use process of the parking equipment of the embodiment is as follows:

[0044] When it is needed to park the vehicle 11 on the loading plate 6, the driving oil cylinder 5 is shortened, which drives the driving rod 2 to rotate forward, and further drives the channel beam 4 and the loading plate 6 thereon to descend forward along an arc track, and finally the bottom surface of the channel beam 4 is supported on the ground, and the channel beam 4 and the loading plate 6 thereon are parked on the ground in front, at this time, the straight line between the second connecting point 8 and the fourth connecting point 10 and the straight line between the third connecting point 9 and the fourth connecting point 10 will keep a certain included angle, that is, a certain pulling force angle A required for pulling up the channel beam. After this, the vehicle can be driven into the loading plate 6, and after the vehicle is parked on the loading plate 6, the driving oil cylinder 5 is elongated, which drives the driving rod 2 to rotate backward, and further drives the channel beam 4 and the loading plate 6 and the vehicle thereon to ascend backward along an arc track, during the ascending process, the pulling force angle A will become larger and larger, and the levelness of the channel beam 4 and the loading plate 6 thereon will become higher and higher, and finally the ascending is completed, and the vehicle 11 will be parked on the second layer position, as shown in the figure. Figure 7

[0045] The above embodiments of the utility model are not the limitation of the protection scope of the utility model, the implementation mode of the utility model is not limited to this, and according to the above content of the utility model, according to the ordinary technical knowledge and usual means in the art, other various forms of modification, replacement or change of the above structure of the utility model are made under the premise of not departing from the above basic technical thought of the utility model, and all should fall within the protection scope of the utility model.​
