Description

Technical Field

[0001] This invention relates to the field of automated parking systems, specifically a comb-type automated parking system suitable for low-rise buildings. Background Technology

[0002] With the continuous growth of urban vehicle ownership, the demand for parking spaces in major commercial areas, public places, social units, and residential areas is correspondingly increasing. However, the construction of parking lots requires a lot of land, and the high cost and scarcity of urban land resources have become a bottleneck in parking lot construction. Currently, high-rise mechanical parking garages are the preferred solution for public parking in cities. High-rise mechanical parking garages make full use of space and save land. In particular, high-rise tower parking systems make full use of space and are very popular in cities.

[0003] Comb-tooth tower parking garages, a common type of tower parking garage, can greatly improve space utilization and enable rapid vehicle storage and retrieval. However, commonly used parking equipment often experiences shaking and vibration during the lifting process. This can cause the vehicle to vibrate, posing a safety hazard. With prolonged use, the lifting chain is prone to breakage due to wear and the tension during system startup, potentially causing the vehicle to fall and be damaged. Furthermore, most transverse comb teeth lack limit mechanisms, resulting in lower safety after vehicle parking. Summary of the Invention

The first hydraulic rod is stretched to drive the second fixing block to slide along the third slide groove. The second hydraulic rod is stretched to drive the third connecting block to move upward, and the rack also moves upward, causing the gear to rotate. The two grippers rotate towards the wheel. After the two grippers clamp the wheel, the second hydraulic rod stops stretching, thus fixing the vehicle.

[0023] Setting a limit mechanism can increase the safety of vehicle parking in the parking area. The second electric cylinder stretches and drives the fifth wedge block to move towards the fourth and sixth wedge blocks. The sixth wedge block drives the support plate to move towards the T-slot. The two third movable blocks are inserted into the T-shaped end of the T-slot. The spring returns to its elasticity and drives the third connecting rod to rotate until it is parallel to the first rotating seat. The position of the support plate is fixed, and the transverse comb frame is limited at the same time. Attached Figure Description

In the initial state, the sliding end of the electric slide 261 is located at the bottom.

[0051] The third hydraulic rod 236 is stretched, causing the upper locking block 28 to move to the outside of the second groove 233. The second moving block 282 also moves to the outside of the second groove 233. At this time, the second moving block 282 locks the first moving block 244, and the position of the first moving block 244 is fixed. When the bottom chain of the lifting system 14 suddenly breaks, the bottom level sensor and tilt sensor of the lifting comb frame 16 send signals, the first electric cylinder 24 is started, and when the tilt angle of the tilt sensor still changes after the friction block 27 abuts against the inner wall of the first slide groove 113, the third hydraulic rod 236 is stretched, and the upper locking block 28 moves to the outside of the second groove 233 and locks between the two protrusions 15.

[0054] The transverse comb frame 17 has a T-slot 171 inside. The crossbeams 112 located on both sides of the parking area in the support frame 11 are equipped with contact sensors and movable limiting mechanisms 4. The limiting mechanism 4 includes a support plate 41. A second electric cylinder 45 is fixedly connected at the bottom center of the crossbeam 112. An installation cavity is opened in the crossbeam 112. A fourth wedge block 46 and a sixth wedge block 461 are elastically connected in the installation cavity.

In the initial state, the first rotating seat 42 is located in the mounting cavity, the third connecting rod 421 rotates to be perpendicular to the first rotating seat 42, and the spring 432 is in a compressed state.

[0056] A rotatable third movable block 44 is symmetrically provided at the port of the support plate 41 away from the sixth wedge block 461, and a torsion spring is built in it.

The other end of the third movable block 44 is provided with a rotatable auxiliary wheel 441. In the initial state, the transverse comb frame 17 is stopped in the parking area. The contact sensor in the crossbeam 112 sends a signal. When the transverse comb frame 17 needs to move laterally to catch the vehicle, the contact sensor sends a signal again, and the second electric cylinder 45 is activated. The support plate 41 moves towards the T-slot 171. The two third movable blocks 44 are inserted into the T-shaped end of the T-slot 171, and the transverse comb frame 17 is fixed, which can increase the safety of vehicle parking in the parking area.

[0057] Working principle:

[0058] In use, the operator drives the vehicle into the parking equipment and parks it on top of the support comb frame 13. After the operator leaves, the parking control system selects the corresponding parking position in the tower garage. The lifting system 14 drives the lifting comb frame 16 to rise along the first slide rail 113 via a chain. After the lifting comb frame 16 rises from the bottom of the support comb frame 13 to be level with the support comb frame 13, the first hydraulic rod 32 is activated. The first hydraulic rod 32 stretches and drives the first fixed block 321 to slide along the fourth slide rail 311, and the second slider 312 also slides accordingly.

[0059] After the second fixing block 33 moves the gripper 35 to the corresponding position of the wheel, the second hydraulic rod 331 is activated. The second hydraulic rod 331 stretches and moves the third connecting block 332 upward. The rack 333 also moves upward, causing the gear 341 to rotate. The two grippers 35 rotate towards the wheel. After the two grippers 35 clamp the wheel, the second hydraulic rod 331 stops stretching, which can fix the vehicle and reduce the risk of the vehicle shaking and falling.

[0060] Then, after the lifting comb frame 16 lifts the vehicle to the designated position, the telescopic rod inside the second hydraulic rod 331 is compressed, causing the gripper 35 to return to its initial state, and the vehicle is unlocked. At the same time, the lateral comb frame 17 slides out of the parking area, the contact sensor inside the crossbeam 112 loses signal, the lifting comb frame 16 descends to the bottom of the supporting comb frame 13 to wait for the next parking, the lateral comb frame 17 catches the vehicle and slides into the parking area, the contact sensor inside the crossbeam 112 sends a signal again, indicating that the lateral comb frame 17 has driven the vehicle to slide into the parking area. At this time, the second electric cylinder 45 is activated, the second electric cylinder 45 stretches and drives the fifth wedge block 451 to move towards the fourth wedge block 46 and the sixth wedge block 461;

[0061] The fourth wedge block 46 and the sixth wedge block 461 are squeezed and move. The sixth wedge block 461 drives the support plate 41 to move towards the T-slot 171. The two third movable blocks 44 are inserted into the T-shaped end of the T-slot 171. The spring 432 restores its elasticity and drives the third connecting rod 421 to rotate parallel to the first rotating seat 42. The position of the support plate 41 is fixed. At the same time, the transverse comb frame 17 is limited, which can increase the safety of parking vehicles in the parking area and ensure that the transverse comb frame 17 will not move randomly when parked, reducing the risk of vehicles falling off.

[0062] During the process of the lifting comb frame 16 driving the vehicle to rise and fall, when the chain at the bottom of the lifting system 14 suddenly breaks, the horizontal sensor and tilt sensor at the bottom of the lifting comb frame 16 send signals to start the first electric cylinder 24. The first electric cylinder 24 stretches and drives the first wedge block 241 to move towards the first slider 22. The first wedge block 241 squeezes the two second wedge blocks 242. The second wedge blocks 242 drive the first connecting rod 25 and the second connecting rod 26 to move towards both ends of the second slide groove 232. The friction block 27 also moves towards the inner wall of the first slide groove 113. The friction block 27 abuts against the inner wall of the first slide groove 113 to increase the friction force.

[0063] Simultaneously, the first rotating rod 252 and the second rotating rod 253 rotate. When the tilt angle inside the tilt sensor no longer changes, it indicates that the lifting comb frame 16 will no longer continue to slide down. The first electric cylinder 24 is turned off and handled by professionals. When the tilt angle inside the tilt sensor still changes, it indicates that the chain at the bottom of the lifting system 14 is severely broken and the friction block 27 can no longer prevent the lifting comb frame 16 from continuing to slide down. The first electric cylinder 24 continues to stretch. When the second wedge block 242 touches the first contact sensor 243, it indicates that the second wedge block 242 has been squeezed to the limit. At this time, the first moving block 244 moves into the second moving block 282.

[0064] The third hydraulic rod 236 stretches and drives the upper locking block 28 to slide outward from the second connecting block 23. The upper locking block 28 pops out from inside the second groove 233 and locks between the two protrusions 15. The second moving block 282 also moves outward from the second groove 233. At this time, the second moving block 282 locks the first moving block 244, and the position of the first moving block 244 is fixed. The first connecting rod 25 and the second connecting rod 26 are limited, the position of the friction block 27 is fixed, and the lifting comb frame 16 is fixed.

[0065] After being fixed, the lifting comb frame 16 is in an inclined state. When the tilt sensor at the bottom of the lifting comb frame 16 detects a tilt angle greater than 3 degrees and less than 10 degrees, the third electric cylinder 263 stretches and drives the lower locking block 264 to engage between the two protrusions 15. At this time, the third hydraulic rod 236 located above the tilt is compressed, driving the upper locking block 28 to retract into the second groove 233. The electric slide 261 is activated, and the sliding end of the electric slide 261 drives the second bracket 262 to move upward. After the second bracket 262 drives the lower locking block 264 to move to the upper end of the third slide groove 235, the inclined lifting comb frame 16 can be pulled back to a horizontal state and wait for professional personnel to handle it, which can reduce the risk of the vehicle slipping.
