Description

Technical Field

[0001] The invention belongs to the technical field of double-layer parking lots, and in particular relates to a double-layer parking space with smooth lifting and lowering. Background Art

[0002] With the improvement of economic level and the continuous increase in the number of cars, the contradiction between supply and demand of urban parking spaces has become increasingly prominent. Especially in old residential areas, commercial complexes, hospitals and other places, the contradiction between supply and demand of parking spaces is particularly prominent. Double-layer parking spaces can effectively solve these problems, not only improving land utilization, but also conforming to the concept of green and low-carbon development. However, in actual use, the existing vertical double-layer parking spaces generally have the problem that the vehicles on the upper parking spaces are parked in a non-central position, resulting in a shift in the overall center of gravity of the upper parking spaces. As a result, when descending, the pressure on the left and right sides is different and the descent speed is different. If the deviation is too large, the vehicle may be scratched or even fall. Therefore, it is very necessary to design a double-layer parking space with stable lifting and lowering. Summary of the invention

[0003] The object of the present invention is to provide a double-deck parking space with smooth lifting and lowering, so as to solve the problems raised by the above-mentioned background technology.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] A double-layer parking space with smooth lifting and lowering comprises a lower parking space, a lifting mechanism and an upper parking space connected in sequence, the lower parking space comprises a bottom plate, the bottom plate is provided with a mechanical safety lock, the lifting mechanism comprises a symmetrically arranged scissor arm, a lifting cylinder and a locking arm, a roller is provided at the lower end of the locking arm, a power supply box and a balancing cylinder are provided on one side of the lower parking space, a pump station is provided on one side of the balancing cylinder, two oil outlet pipelines and two oil inlet pipelines are provided on the balancing cylinder, the two oil outlet pipelines are respectively connected to the two lifting cylinders, the two oil inlet pipelines are connected to the pump station, a throttle valve and an overflow valve are provided in the pump station, and a plurality of detachable batteries are provided in the power supply box.

[0006] Furthermore, a cylinder explosion-proof valve is provided on one side of the lifting cylinder.

[0007] Furthermore, two batteries are arranged in the power box.

[0008] Furthermore, the battery is a rechargeable battery.

[0009] Furthermore, a tee is provided between the two oil inlet pipelines and the pump station.

[0010] Furthermore, the upper parking space is provided with tire grooves.

[0011] Furthermore, the pump station is arranged inside the electric control cabinet.

[0012] Furthermore, an electromagnetic unloading valve is provided in the pump station.

[0013] Furthermore, the mechanical safety lock is fixed to one side of the lower end of the locking arm.

[0014] The present invention has the following beneficial effects:

[0015] The present invention can improve the space utilization rate of parking spaces and park two vehicles at the same time. The upper parking space can lift vehicles weighing up to 2700 kg. The lifting height of the upper parking space can be adjusted according to the height of the parked vehicles to meet the height requirements of most vehicles. The use effect is good, the adaptability is good, the working noise is small, and can reach below 80db. A detachable battery is provided, and it can be used in places without power supply, which greatly increases the use range of the equipment, can achieve smooth rise and fall, and has a good use experience.

[0016] The present invention can be remotely controlled by a remote controller, or manually controlled by a pump station, and multiple operation modes are combined, the operation is simple, and the problem of affecting the normal use of the vehicle when the remote controller is lost is avoided. The adaptability is good and the use effect is good;

[0017] Equipped with a mechanical safety lock, when the upper parking space is raised into place, the mechanical safety lock is automatically locked, and the weight of the vehicle in the upper parking space is firmly pressed on the safety lock, without any additional hydraulic energy, reducing the use cost. When the power supply is turned off or the power is interrupted or the hydraulic system leaks, the safety lock remains locked and does not move until it is unlocked by manual control or remote control. The operation is simple, the overall safety factor is high, the use effect is good, and the work efficiency is high;

[0018] By setting up a balancing cylinder, when the upper vehicle is parked to one side and the center of gravity is not centered, the hydraulic system can still automatically adjust to achieve a smooth and uniform descent on both sides, which improves the overall safety factor and user experience, and has strong adaptability;

[0019] By setting the throttle valve, users can adjust the descent speed of the parking space according to their own experience or personal habits. For example, when the descent speed is fast, the problem of excessive sound when it touches the ground can be solved by reducing the descent speed. It is simple to operate, highly adaptable and highly efficient.

[0020] By setting the overflow valve, the system pressure can be adjusted to change the lifting capacity of the parking space, which has better adaptability and better use effect;

[0021] By setting up a removable battery and changing the existing 220V / 380V power supply to 24V power supply, the parking space can be used in places without power supply. Through battery power supply, when the battery power is low or insufficient, a new fully charged battery can be directly replaced. It has strong adaptability and good use effect. The used battery can be fully charged and recycled again.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] See also Figure 1-3 As shown, the present invention is a double-layer parking space that can be lifted and lowered stably. Figure 1As shown, the smoothly lifting double-layer parking space of this embodiment includes a lower parking space 1, a lifting mechanism and an upper parking space 2 connected in sequence. The lower parking space 1 includes a base plate 11, on which a mechanical safety lock 9 is provided. The lifting mechanism includes symmetrically arranged scissor arms 7, a lifting cylinder 6 and a locking arm 8, and a roller 12 is provided at the lower end of the locking arm 8. A power box 4 and a balancing cylinder 3 are provided on one side of the lower parking space 1, and a pump station is provided on one side of the balancing cylinder 3. Two oil outlet pipelines and two oil inlet pipelines are provided on the balancing cylinder 3, and the two oil outlet pipelines are respectively connected to the two lifting cylinders 6, and the two oil inlet pipelines are connected to the pump station. A throttle valve 52 and an overflow valve 53 are provided in the pump station, and a plurality of detachable batteries are provided in the power box 4.

[0030] A cylinder explosion-proof valve is provided on one side of the lifting cylinder 6.

[0031] Two batteries are arranged in the power supply box 4 .

[0032] The battery is a rechargeable battery.

[0033] A tee is provided between the two oil inlet pipelines and the pump station.

[0034] The upper parking space 2 is provided with tire grooves 22 and damping strips 21 .

[0035] The pump station is arranged inside the electric control cabinet 5 .

[0036] An electromagnetic unloading valve 51 is provided in the pump station.

[0037] The mechanical safety lock 9 is fixed to one side of the lower end of the locking arm 8 .

[0038] When working, the initial position of the double-layer parking space is the lowest position. The vehicle is parked in the upper parking space 2 by reverse parking. After parking in place, the rear wheel hub of the vehicle falls into the tire groove 22. After the driver gets off the vehicle, he presses the up button on the remote control to control the lifting mechanism to rise.

[0039] By pressing the rising button on the remote control or manually operating the electric control cabinet 5, the mechanical safety lock 9 is unlocked. During the rising process of the parking space, the motor 55 drives the gear pump 54 to pump the hydraulic oil into the balancing cylinder 3. The balancing cylinder 3 evenly distributes the hydraulic oil to the lifting cylinder 6 through two oil outlets. The lifting cylinder 6 drives the lifter to gradually rise. The roller 12 slides to the right and successively crosses the stop block 91 until it rises to a suitable height. The mechanical safety lock 9 is stuck on the stop block 91;

[0040] By pressing the up button via the remote control or manually operating the electric control cabinet 5, the mechanical safety lock 9 is unlocked, and the hydraulic oil stored in the balancing cylinder 3 is pushed back to the pump station. Although the center of gravity of the vehicle is not centered, the balancing cylinder 3 will always keep the oil volume in the two lifting cylinders 6 balanced, allowing it to descend smoothly until it falls back to the lowest position.

[0041] See also Figure 3 , two rollers 12 are provided on the locking arm 8 on each side of the parking space, and a connecting shaft is provided between the two rollers 12. A connecting cylinder fixedly connected to the locking arm 8 is provided on the outer side of the connecting shaft, and a fixedly connected mechanical safety lock 9 is provided on one side of the connecting cylinder. The mechanical safety lock 9 includes a safety block in the shape of a number 7. The recessed part of the safety block can be stuck with the stop block 91. When the two are stuck, the safety lock is locked. A through groove is provided in the middle of the safety block, and a rotatably connected adjustment plate is provided inside. The shape of the adjustment plate is a right-angled trapezoid; when the parking space rises, the locking arm 8 drives the mechanical safety lock 9 to move right, and the adjustment plate rotates to the left along the upper axis after encountering the stop block 91 and slides over the stop block 91 until the lifting mechanism rises to a suitable position and the adjustment plate contacts and locks with the stop block 91, that is, the mechanical safety lock 9 is in a locked state; when the parking space is lowered, the locking arm 8 drives the mechanical safety lock 9 to slide to the right first to unlock and then move to the left. After the adjustment plate encounters the stop block 91, it stands up and drives the safety block to cross the stop block 91 until the lifting mechanism drops to the lowest position.

[0042] The present invention can improve the space utilization rate of parking spaces and park two vehicles at the same time. The upper parking space 2 can lift vehicles weighing up to 2700 kg. The lifting height of the upper parking space 2 can be adjusted according to the height of the parked vehicles, meeting the height requirements of most vehicles. The use effect is good, the adaptability is good, the working noise is small, and can reach below 80db. A detachable battery is provided, and it can be used in places without power supply, which greatly increases the use range of the equipment, can achieve smooth rise and fall, and has a good use experience.

[0043] The present invention can be remotely controlled by a remote controller, or manually controlled by a pump station, and multiple operation modes are combined, the operation is simple, and the problem of affecting the normal use of the vehicle when the remote controller is lost is avoided. The adaptability is good and the use effect is good;

[0044] The present invention is provided with a mechanical safety lock 9. When the upper parking space 2 is raised to a position, the mechanical safety lock 9 is automatically locked. The weight of the vehicle in the upper parking space 2 is firmly pressed on the safety lock. No additional hydraulic energy is required, which reduces the use cost. When the power supply is turned off or the power supply is interrupted or the hydraulic system leaks, the safety lock remains locked and does not move until it is unlocked by manual control or remote control. The operation is simple, the overall safety factor is high, the use effect is good, and the work efficiency is high.

[0045] By setting the balancing cylinder 3, when the upper vehicle is parked to one side and the center of gravity is not centered, the hydraulic system can still be automatically adjusted to achieve a smooth and uniform descent on both sides, thereby improving the overall safety factor and user experience, and having strong adaptability;

[0046] By setting the throttle valve 52, the user can adjust the descent speed of the parking space according to his own experience or personal habits. For example, when the descent speed is fast, the problem of excessive sound when contacting the ground can be solved by reducing the descent speed. The operation is simple, the adaptability is strong, and the work efficiency is high.

[0047] By setting the overflow valve 53, the system pressure can be adjusted to change the lifting capacity of the parking space, which has better adaptability and better use effect;

[0048] By setting up a removable battery and changing the existing 220V / 380V power supply to 24V power supply, the parking space can be used in places without power supply.
