For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] As attached Figure 1-6 As shown, an intelligent overload limit safety and anti-sway system for a vertical circulation mechanical parking device includes a control unit, a power unit 1 and a lifting unit 3 connected in sequence. The lifting unit is arranged below the vehicle loading plate 2 of the parking device. The lifting unit 3 includes a hydraulic cylinder 14 arranged on a base 15. The hydraulic cylinder 14 is connected to the power unit 1. A horizontal lifting plate 13 is fixed to the top of the piston rod of the hydraulic cylinder 14. A buffer pad 11 is fixed to the top of the lifting plate 13. When the lifting plate 13 is raised, the buffer pad 11 abuts against the bottom end of the vehicle loading plate 2.
[0027] A horizontal top plate 10 is fixed to the top of the hydraulic cylinder 14, and a plurality of vertical guide sleeves 9 are arranged on the edge of the top plate 10. A plurality of guide rods 7 are fixed to the edge of the lifting plate 13, and the guide rods 7 are arranged in the guide sleeve 9 to slide up and down. A circle of shaft sleeves 8 is arranged on the outside of the guide sleeve 9 to guide the guide rods 7. The base 15 is fixed to the ground by chemical anchor bolts 16, and a reinforcing plate 5 is fixed to the side of the hydraulic cylinder 14, and the reinforcing plate 5 is fixed to the side of the hydraulic cylinder 14 by reinforcing bolts 6. The reinforcing bolts 6 press the reinforcing plate 5 and the hydraulic cylinder 14 to prevent the hydraulic cylinder 14 from overturning under force. A conical sleeve 12 is fixed to the top of the piston rod of the hydraulic cylinder 14, and the conical sleeve 12 is connected and fixed together with the buffer pad 11 by bolts, and the buffer pad 11 can be pressed against the lifting plate 13 by the conical sleeve. The power unit 1 includes an oil pump. The hydraulic cylinder 14 is connected to the power unit 1 through a hydraulic oil pipe 4. A plurality of tees or crosses are provided at the connection of the hydraulic oil pipe 4. A hydraulic oil gauge is provided on the power unit 1.
[0028] A lower limit sensor 17 is fixedly mounted on the top plate 10 to detect whether the lifting plate 13 has fallen down, so as to avoid the lifting plate 13 from being scratched against the vehicle loading plate 2 when in a raised state.
[0029] In another embodiment of the present application, a pressure sensor 18 is provided between the lifting plate 13 and the top plate 10 , the piston rod of the hydraulic cylinder 14 passes through the pressure sensor 18 , and the top surface of the pressure sensor 18 is connected to the bottom surface of the lifting plate 13 .
[0030] The working principle of this utility model:
[0031] 1. After the vehicle loading plate 2 runs to the entrance and exit layer, the power unit 1 runs under the control of the control unit, driving the piston rod of the hydraulic cylinder 14 in the lifting unit 3 to rise. After the hydraulic system reaches the set pressure, the piston rod stops rising, and finally the buffer pad 11 on the lifting plate 13 contacts the bottom of the crossbeam of the vehicle loading plate 2. At this time, the pressure sensor 18 sends the data to the electrical control system and resets the current pressure. After the car enters the vehicle loading plate 2, the pressure sensor 18 sends the new pressure data to the control system, and the electrical control system judges the weight data of the car. If the car exceeds the rated weight, the garage will not respond to the parking instruction;
[0032] 2. After the user makes a parking or retrieving operation, the piston rod of the hydraulic cylinder 14 of the lifting unit 3 falls down, the lifting plate 13 and the buffer pad 11 return to their original positions, and at the same time, the lower limit sensor 17 receives a signal, and the garage starts to operate.
[0033] Functions and advantages of this utility model:
[0034] 1. After the hydraulic cylinder 14 is raised, it can prevent the vehicle from shaking when entering and exiting the loading plate 2, improve the user's comfort and sense of security, and reduce the amount of forward and backward shaking of the vehicle when entering the loading plate 2, thereby avoiding fatigue deformation caused by the forward and backward shaking of the pallet, and at the same time, avoiding damage to the triangle plate and chain due to the forward and backward shaking of the loading plate 2;
[0035] 2. A buffer pad 11 is provided on the lifting plate 13 to avoid hard contact between steel and steel, reduce impact and noise, and increase friction.
[0036] 3. The upper limit position of the piston rod is controlled by setting a certain oil pressure, which can adapt to vehicle loading plates 2 of different heights and can have good contact with the cross beam of the vehicle loading plate 2. After the piston rod falls, there is a lower limit sensor 17 to prevent the piston rod from being in a raised state and scratching the vehicle loading plate 2, which has high safety.
[0037] 4. The weight of the vehicle parked in the garage can be detected. If the weight is less than the rated load of the equipment, the vehicle can be stored and retrieved normally. If the weight is greater than the rated load of the equipment, the storage action will not be performed to prevent deformation and damage of the garage loading plate, connecting beam and other components, thereby improving safety.
