Description

Technical Field

[0001] The invention relates to the field of three-dimensional parking equipment, and in particular to a double-car plate exchange vehicle picking machine. Background Art

[0002] With the progress of society and the improvement of people's living standards, cars have become more and more popular. However, with the sharp increase in the number of private cars, parking has become the top problem faced by car owners. As the country vigorously promotes the urbanization process, the urban population continues to expand, urban land is becoming increasingly tight, and prime locations are extremely expensive, resulting in unprecedented tension in urban parking spaces. Therefore, mechanical multi-story parking garages came into being.

[0003] Existing car picking machines all adopt a single-layer single-vehicle board structure. Therefore, when the car picking machine places the vehicle loading board and the car on the vehicle loading board into the parking space, if it is necessary to continue the next vehicle transportation, it may often be necessary to take a vehicle loading board from other empty parking spaces to meet the transportation of the next vehicle. Such a car picking machine with a single-layer single-vehicle board structure separates the two actions of placing the vehicle loading board and taking the vehicle loading board, which wastes a lot of time and has the disadvantages of low efficiency and high cost.

[0025] See also Figures 1 to 7 , showing that the present invention provides a double-car plate exchange pick-up machine 100, which includes a frame 1, an upper micro-motion mechanism 2, a lower micro-motion mechanism 3, an upper-layer pick-up mechanism 4 and a lower-layer pick-up mechanism 5. The frame 1 is a frame structure, the upper-layer pick-up mechanism 4 is located above the lower-layer pick-up mechanism 5, the upper micro-motion mechanism 2 and the lower micro-motion mechanism 3 are located in the middle of the frame 1, the upper micro-motion mechanism 2 is located above the lower micro-motion mechanism 3, the upper micro-motion mechanism 2 and the lower micro-motion mechanism 3 are both installed on the frame 1, the upper-layer pick-up mechanism 4 is installed at the output end of the upper micro-motion mechanism 2, the upper-layer pick-up mechanism 4 is driven by the upper micro-motion mechanism 2 to move laterally to approach or move away from the parking space, and when the pick-up machine is raised or lowered to the target height, the upper-layer pick-up mechanism 4 can be driven by the upper micro-motion mechanism 2 to move laterally to approach or move away from the parking space (the lateral movement direction is as shown in FIG. 1 ). Figure 4 The upper vehicle picking mechanism 4 is used to put the upper vehicle loading plate 10 into or take it out of the upper station of the parking space, so as to achieve the purpose of taking out and putting in the upper vehicle loading plate 10; the lower vehicle picking mechanism 5 is installed at the output end of the lower micro-motion mechanism 3, and the lower vehicle picking mechanism 5 is driven by the lower micro-motion mechanism 3 to move horizontally to approach or move away from the parking space (the horizontal movement direction is as shown in FIG. Figure 5The lower layer pick-up mechanism 5 is used to put the lower layer car board 20 into or take it out of the lower layer workstation of the parking space, so as to achieve the purpose of taking out and putting in the lower layer car board 20.

In this way, the defect of having to take the car board from another parking space due to different places can be avoided, and the two actions of placing and taking the car board can be realized simultaneously, which not only saves a lot of time, but also has the advantages of simple structure, high efficiency and low cost. More specifically, as follows:

[0026] See also Figure 4 The upper micro-motion mechanism 2 includes an upper telescopic micro-motion driving device 21 and a moving seat 22. The moving seat 22 is connected to the output end of the upper telescopic micro-motion driving device 21. The moving seat 22 is connected to the upper vehicle picking mechanism 4. The upper telescopic micro-motion driving device 21 drives the moving seat 22 to make a linear reciprocating movement along the left and right directions of the frame 1 (the left and right directions are as follows). Figure 4 The upper telescopic micro-motion driving device 21 is, for example, a rotary motor, a screw rod 23 arranged along the left and right directions of the frame 1 is installed at the output end of the rotary motor, a nut (not shown) is installed on the moving seat 22, and the nut is slidably sleeved on the screw rod 23. Of course, in other embodiments, the driving device may also be a driving motor or a driving cylinder, but is not limited thereto.

The moving seat 32 is connected to the output end of the lower telescopic micro-motion driving device 31. The moving seat 32 is connected to the lower car picking mechanism 5. The lower telescopic micro-motion driving device 31 drives the moving seat 32 to move back and forth in a straight line along the left and right directions of the frame 1 to drive the lower car picking mechanism 5 to move (the left and right directions are as follows: Figure 5 For example, the lower telescopic micro-motion driving device 31 is a rotary motor, and a screw rod 33 arranged along the left and right direction of the frame 1 is installed at the output end of the rotary motor, and a nut (not shown) is installed under the movable seat 32, and the nut is slidably sleeved on the screw rod 33. Of course, in other embodiments, the driving device can also be a driving motor or a driving cylinder, but is not limited thereto.

[0028] See also Figure 4 as well as Figure 6The upper vehicle pickup mechanism 4 includes an upper moving frame 41, a left transmission device 42, a right transmission device 43 and an upper tensioning structure 44. The upper moving frame 41 is installed at the output end of the upper micro-motion mechanism 2. The upper moving frame 41 moves horizontally along the left and right directions of the frame 1 under the drive of the upper micro-motion mechanism 2. The left transmission device 42 and the right transmission device 43 are installed on the left and right sides of the upper moving frame 41 along the left and right directions of the frame 1. The upper vehicle loading plate 10 is moved by the transmission of the left transmission device 42 and the right transmission device 43, so as to move the upper vehicle loading plate 10 on the vehicle pickup machine to the parking space, or move the upper vehicle loading plate 10 on the parking space to the vehicle pickup machine. For example, please refer to Figure 6The left transmission device 42 includes a transmission drive device 421, an upper driving wheel 422, a lower driving wheel 423, an upper pinching wheel 424 and a lower pinching wheel 425. The upper driving wheel 422 and the lower driving wheel 423 are both installed at the output end of the transmission drive device 421. The upper driving wheel 422 and the lower driving wheel 423 rotate under the drive of the transmission drive device 421. The upper pinching wheel 424 and the lower pinching wheel 425 are relatively arranged along the up and down direction of the frame 1, and a clamping gap is formed between the upper pinching wheel 424 and the lower pinching wheel 425. The feeding wheel 424 is connected to the upper driving wheel 422 by transmission, and the lower pinching wheel 425 is connected to the lower driving wheel 423 by transmission. Therefore, the upper pinching wheel 424 rotates under the drive of the upper driving wheel 422, and the lower pinching wheel 425 rotates under the drive of the lower driving wheel 423. Therefore, the upper pinching wheel 424 and the lower pinching wheel 425 send the upper vehicle loading plate 10 into or out of the parking space through the action of clamping force and rolling. The right transmission device 43 includes a transmission driving device 431, an upper driving wheel 432, a lower driving wheel 433, an upper pinching wheel 43 4 and lower pinch wheels 435, the upper driving wheel 432 and the lower driving wheel 433 are all installed at the output end of the transmission driving device 431, the upper driving wheel 432 and the lower driving wheel 433 are driven to rotate by the transmission driving device 431, the upper pinch wheel 434 and the lower pinch wheel 435 are relatively arranged along the up and down direction of the frame 1, and a clamping gap is formed between the upper pinch wheel 434 and the lower pinch wheel 435, the upper pinch wheel 434 is connected to the upper driving wheel 432, and the lower pinch wheel 435 is connected to the lower driving wheel 433, so the upper pinch wheel 434 is connected to the upper driving wheel 432. The delivery wheel 434 rotates under the drive of the upper driving wheel 432, and the lower pinching wheel 435 rotates under the drive of the lower driving wheel 433. Therefore, the upper pinching wheel 434 and the lower pinching wheel 435 send the upper car loading plate 10 into or out of the parking space through the action of clamping force and rolling. Due to the use of a clamping transmission structure, it saves more space than other traditional transmission devices and reduces the overall volume of the device to adapt to the relatively narrow space in the garage, thereby meeting the requirement of parking a 1550mm high car under a floor height clearance of 2100mm. In this embodiment, the upper driving wheel 432, the lower driving wheel 433, the upper pinching wheel 434 and the lower pinching wheel 435 are all sprockets. The upper pinching wheel 434 is connected to the upper driving wheel 432 by chain transmission, and the lower pinching wheel 435 is connected to the lower driving wheel 433 by chain transmission. An upper tensioning structure 44 is provided between the upper pinching wheel 434 and the upper driving wheel 432 and between the lower pinching wheel 435 and the lower driving wheel 433. In this embodiment, the upper tensioning structure 44 is a tensioning wheel, but is not limited to this.

[0029] See also Figure 5 as well as Figure 7The lower-layer vehicle picking mechanism 5 includes a lower moving frame 51, a left transmission device 52, a right transmission device 53 and a lower tensioning structure 54. The lower moving frame 51 is installed at the output end of the lower micro-motion mechanism 3. The lower moving frame 51 moves horizontally along the left and right directions of the frame 1 under the drive of the lower micro-motion mechanism 3. The left transmission device 52 and the right transmission device 53 are installed on the left and right sides of the lower moving frame 51 along the left and right directions of the frame 1. The lower-layer vehicle loading plate 20 is moved by the transmission of the left transmission device 52 and the right transmission device 53, so as to transport the lower-layer vehicle loading plate 20 on the vehicle picking machine to the parking space, or transport the lower-layer vehicle loading plate 20 on the parking space to the vehicle picking machine. For example, the left transmission device 52 includes a transmission drive device 521, an upper driving wheel 522, a lower driving wheel 523, an upper pinching wheel 524 and a lower pinching wheel 525. The upper driving wheel 522 and the lower driving wheel 523 are both installed at the output end of the transmission drive device 521. The upper driving wheel 522 and the lower driving wheel 523 rotate under the drive of the transmission drive device 521. The upper pinching wheel 524 and the lower pinching wheel 525 are arranged opposite to each other along the up and down direction of the frame 1, and a clamping gap is formed between the upper pinching wheel 524 and the lower pinching wheel 525. The upper pinch wheel 524 is connected to the upper driving wheel 522 by transmission, and the lower pinch wheel 525 is connected to the lower driving wheel 523 by transmission. Therefore, the upper pinch wheel 524 rotates under the drive of the upper driving wheel 522, and the lower pinch wheel 525 rotates under the drive of the lower driving wheel 523. Therefore, the upper pinch wheel 524 and the lower pinch wheel 525 send the upper vehicle loading plate 10 into or out of the parking space through the action of clamping force and rolling. The right transmission device 53 includes a transmission drive device 531, an upper driving wheel 532, a lower driving wheel 533, an upper pinch wheel 534 and the lower pinch wheel 535, the upper driving wheel 532 and the lower driving wheel 533 are all installed at the output end of the transmission driving device 531, the upper driving wheel 532 and the lower driving wheel 533 are driven to rotate by the transmission driving device 531, the upper pinch wheel 534 and the lower pinch wheel 535 are relatively arranged along the up and down direction of the frame 1, and a clamping gap is formed between the upper pinch wheel 534 and the lower pinch wheel 535, the upper pinch wheel 534 is connected to the upper driving wheel 532, and the lower pinch wheel 535 is connected to the lower driving wheel 533, so the upper The pinch wheel 534 rotates under the drive of the upper driving wheel 532, and the lower pinch wheel 535 rotates under the drive of the lower driving wheel 533. Therefore, the upper pinch wheel 534 and the lower pinch wheel 535 send the lower car loading plate 20 into or out of the parking space through the action of clamping force and rolling. Due to the clamping transmission structure, it saves more space than other traditional transmission devices and reduces the overall volume of the device to adapt to the relatively narrow space in the garage, thereby meeting the requirement of parking a 1550mm high car under a floor height clearance of 2100mm.In this embodiment, the upper driving wheel 532, the lower driving wheel 533, the upper pinching wheel 534 and the lower pinching wheel 535 are sprockets. The upper pinching wheel 534 is connected to the upper driving wheel 532 by chain transmission, and the lower pinching wheel 535 is connected to the lower driving wheel 533 by chain transmission. A lower tensioning structure 54 is provided between the upper pinching wheel 534 and the upper driving wheel 532 and between the lower pinching wheel 535 and the lower driving wheel 533. In this embodiment, the lower tensioning structure 54 is a tensioning wheel, but is not limited to this.

[0030] Combined with Figures 1 to 7 The working principle of the double-car plate exchange vehicle pickup machine 100 of the present invention is described in detail as follows:

[0031] When parking the car, the upper-layer car picking mechanism 4 moves laterally under the drive of the upper micro-motion mechanism 2 to approach the parking space, and the lower-layer car picking mechanism 5 moves laterally under the drive of the lower micro-motion mechanism 3 to approach the parking space. The upper-layer car picking mechanism 4 puts the upper-layer car loading plate 10 at the upper-layer station of the car picking machine into the upper-layer station of the parking space. At the same time, the lower-layer car picking mechanism 5 takes out the lower-layer car loading plate 20 at the lower-layer station of the parking space and puts it into the lower-layer station of the car picking machine, thereby realizing parking and placing the plate by switching the upper-layer car loading plate 10 and the lower-layer car loading plate 20. After parking the car, the upper-layer car picking mechanism 4 moves laterally under the drive of the upper micro-motion mechanism 2 to move away from the parking space, and the lower-layer car picking mechanism 5 moves laterally under the drive of the lower micro-motion mechanism 3 to move away from the parking space.

[0032] When picking up a car, the upper-layer car picking mechanism 4 moves laterally under the drive of the upper micro-motion mechanism 2 to approach the parking space, and the lower-layer car picking mechanism 5 moves laterally under the drive of the lower micro-motion mechanism 3 to approach the parking space. The upper-layer car picking mechanism 4 takes out the upper-layer car loading plate 10 at the upper-layer workstation of the parking space and puts it into the upper-layer workstation of the car picking machine. At the same time, the lower-layer car picking mechanism 5 takes out the lower-layer car loading plate 20 at the lower-layer workstation of the car picking machine and puts it into the lower-layer workstation of the parking space, thereby realizing the picking up and placing of the plates by switching the upper-layer car loading plate 10 and the lower-layer car loading plate 20. After the car is picked up, the upper-layer car picking mechanism 4 moves laterally under the drive of the upper micro-motion mechanism 2 to move away from the parking space, and the lower-layer car picking mechanism 5 moves laterally under the drive of the lower micro-motion mechanism 3 to move away from the parking space. It is understandable that the upper loading plate 10 and the lower loading plate 20 can be switched in position by other devices when in a parking space or when picking up a vehicle, that is, the upper loading plate 10 can be switched to the lower loading plate 20 by lifting, and the lower loading plate 20 can be switched to the upper loading plate 10 by lifting.

[0033] By combining the upper micro-motion mechanism 2, the lower micro-motion mechanism 3, the upper-layer car picking mechanism 4 and the lower-layer car picking mechanism 5 together, the upper-layer car picking mechanism 4 is installed at the output end of the upper micro-motion mechanism 2, and the upper-layer car picking mechanism 4 is driven by the upper micro-motion mechanism 2 to move horizontally to approach or move away from the parking space. When the car picking machine is lifted to the target height, the upper-layer car picking mechanism 4 can be driven by the upper micro-motion mechanism 2 to move horizontally to approach or move away from the parking space, so as to facilitate the subsequent placement or removal of the upper-layer car loading plate 10. The upper-layer car picking mechanism 4 is used to place the upper-layer car loading plate 10 into the upper-layer workstation of the parking space or take it out, so as to achieve the purpose of taking out and placing the upper-layer car loading plate 10; the lower-layer car picking mechanism 5 is installed at the output end of the lower micro-motion mechanism 3, and the lower-layer car picking mechanism 5 is driven by the lower micro-motion mechanism 3 to move horizontally to approach or move away from the parking space. When the car picking machine is lifted to the target height, the lower-layer car picking mechanism 5 The lower vehicle pick-up mechanism 5 is used to place the lower vehicle plate 20 in the lower station of the parking space or take it out, so as to achieve the purpose of taking out and placing the lower vehicle plate 20. In other words, with the cooperation of the upper vehicle pick-up mechanism 4 and the lower vehicle pick-up mechanism 5, the upper vehicle pick-up mechanism 4 takes out the upper vehicle plate 10 while the lower vehicle pick-up mechanism 5 puts in the lower vehicle plate 20, and the upper vehicle pick-up mechanism 4 puts in the upper vehicle plate 10 while the lower vehicle pick-up mechanism 5 takes out the lower vehicle plate 20. In this way, the defect of having to take the vehicle plate from another parking space due to different places can be avoided, and the two actions of placing and taking the vehicle plate can be realized simultaneously, which not only saves a lot of time, but also has the advantages of simple structure, high efficiency and low cost.

[0034] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
