AI Technical Summary
The lifting point of the lifting and loading plate of traditional mechanical parking equipment is too close to the loading plate, which makes parking difficult.
A lifting point width adjustment structure for lifting and lowering parking spaces is designed. The lifting point distance is adjusted by the swing connection arm and the swing block arranged at the side end of the load frame by using the upper and lower swinging arm and the chain cable joint on the swing block of the swing connection arm.
The distance between the lifting points is variable through swing, and the distance between the loading points becomes wider when the loading board is lowered, making it easier to park vehicles. The distance between the lifting points becomes narrower when the loading board is lifted, which avoids more width for adjacent parking spaces and facilitates adjacent vehicles to park.

At present, the lifting and traversing type parking equipment accounts for the highest proportion in the market. The working principle of the lifting and traversing type mechanical parking equipment is that the car carrier plate first moves to the bottom layer, the driver drives the vehicle into the car carrier plate, and then the car carrier plate moves up and down and left and right to realize the parking operation. When leaving the vehicle, it is first judged whether there is an empty space for movement, and then the vehicle is moved out. This type of parking equipment has the advantages of simple structure, low construction cost and short time.
[0004] The lifting car carrier plates of traditional mechanical parking equipment such as the lifting and traversing type and the simple lifting type are restricted by the site, the width of the lifting car carrier plate is small, and the distance between the suspension points of the lifting car carrier plate is also small. The small lifting distance affects the driver's parking experience, and the hoisting structure with a small distance is also not conducive to the intelligent transformation of the lifting and traversing type and simple lifting type parking equipment with AGV.

Specific implementation mode
[0027] Embodiment 1:
[0028] As Figure 1 shown, a hoisting point width adjustment structure for a liftable parking space includes a swing connecting arm 1 arranged at the side end of the carrier frame 2. The swing connecting arm 1 is hinged to the carrier frame 2 so that the swing connecting arm 1 can swing up and down. A swing block 6 is also provided. The swing block 6 is used to connect to the end of the swing connecting arm 1 away from the carrier frame 2. A cable joint 5 is provided on the swing block 6, and the cable joint 5 is connected to the lower end of the lifting traction cable 3.
[0029] The side ends of the carrier frame 2 are provided with stop blocks 202. One end of the swing connecting arm 1 close to the carrier frame 2 is provided with an extension section 109. The end of the extension section 109 is provided with a rotatable roller 108. The carrier frame 2 is lifted so that the swing connecting arm 1 is arranged obliquely and abuts against the end of the stop block 202.
[0030] When the carrier frame 2 is lowered, since the swing connecting arm 1 is in an inclined state and the center of gravity is biased towards the outside, plus the lever action generated by the roller 108 abutting against and rolling on the ground surface, the swing connecting arm 1 is finally flattened.
[0031] Embodiment 2:
[0032] As Figures 2 - 10 , a suspension point width adjustment structure for a liftable parking space, includes a swing connecting arm 1 arranged at the side end of the carrier frame 2. The swing connecting arm 1 includes a first swing arm 101 and a second swing arm 102. One end of the first swing arm 101 is hinged to the carrier frame 2 so that the first swing arm 101 can swing up and down. The other end of the first swing arm 101 is hinged to the lower end of the second swing arm 102. A swing block 6 is provided on the second swing arm 102. A chain cable joint 5 is provided on the swing block 6. The chain cable joint 5 is connected to the lower end of the lifting traction chain cable 3. The first swing arm 101 abuts against the ground 7 so that the first swing arm 101 and the second swing arm 102 are arranged at a right angle. The lifting traction chain cable 3 pulls up the carrier frame 2 so that the first swing arm 101 and the second swing arm 102 are arranged in a straight line.
[0033] The lifting traction chain cable 3 is a chain or a steel cable.
[0034] For a double-layer liftable parking space in a general garage, a reduction motor is used to drive the lifting traction chain cable 3 to lift the carrier frame 2. The carrier frame 2 is rectangular. A connection hole 504 is provided on the chain cable joint 5. If the lifting traction chain cable 3 is a steel cable, the steel cable is passed through the connection hole 504 and the end of the steel cable is bent back and crimped together by a clip. If the lifting traction chain cable 3 is a chain, the swing connecting arm 1 inserts the chain link column into the connection hole 504. The lifting traction chain cable 3 is connected to the hinge ears 201 at the four corners of the carrier frame 2 through the swing connecting arm 1. Generally, the swing connecting arm 1 is a fixed connecting plate that extends outward to the left and right to widen the space in the vehicle width direction. However, since the liftable parking spaces are usually densely arranged, the widened space width is at most one-half of the space between the parking spaces. Compared with ordinary parking spaces, it is still very narrow and it is easy for the vehicle to be scratched by the lifting traction chain cable 3.
[0035] In this solution, when the carrier frame 2 is lifted, the lifting traction chain cable 3 is in a taut state, and the first swing arm 101 and the second swing arm 102 are pulled into a vertical state. Therefore, the swing inward reduces the width in the vehicle width direction. At this time, since the lifting traction chain cable 3 is also forced to narrow inward, the adjacent parking space has a larger space in the vehicle width direction. The lifting traction chain cable 3 of the adjacent parking space is lowered, and its first swing arm 101 lies flat on the foundation 7 under the action of gravity. Since the upper suspension point position of the lifting traction chain cable 3 is inward, the lifting traction chain cable 3 inclines slightly inward. The second swing arm 102 has a tendency to close, but a stop end 105 is provided at the lower end of the second swing arm 102. The stop end 105 abuts against the first swing arm 101, and the second swing arm 102 remains vertical. One side in the vehicle width direction of the parking space is widened by the length of a first swing arm 101, and the vehicle width direction of the parking space approaches that of a normal parking space, greatly reducing the risk of scratching.
[0036] In a preferred solution, a stop block 202 is provided at the side end of the carrier frame 2. The stop block 202 stops the first swing arm 101. A second magnetic block 203 is provided at the end of the stop block 202, and a first magnetic block 106 is provided on the first swing arm 101. The first magnetic block 106 repels the second magnetic block 203.
[0037] When the first swing arm 101 is vertical, it is abutted by the stop block 202. At this time, since the lifting traction chain cable 3 is in a stressed and taut state, the acting force is much greater than the repulsive force of the stop block 202 on the first magnetic block 106. Therefore, the first swing arm 101 still clings to the end of the stop block 202. When the carrier frame 2 is placed on the foundation 7, the lifting traction chain cable 3 gradually becomes slack, and the second magnetic block 203 repels the first magnetic block 106 to push the first swing arm 101 away, and the first swing arm 101 lies flat under the action of gravity.
[0038] In a preferred solution, a sunk groove 701 is provided on the foundation 7. A raised cushion block 702 is provided in the sunk groove 701. An avoidance hole 104 is provided in the center of the first swing arm 101. A reinforcing rib 103 is provided outside the avoidance hole 104 on the first swing arm 101. When the first swing arm 101 rotates and lies flat, the raised cushion block 702 is inserted into the avoidance hole 104, and the upper end of the reinforcing rib 103 is flush with the upper end surface of the foundation 7.
[0039] The first swing arm 101 is embedded in the sunk groove 701 to prevent the first swing arm 101 and the hinge joint from being damaged due to frequent rolling when a vehicle or an AGV vehicle handling tool passes by. The carrier frame 2 generally adopts a rectangular welded frame structure with a support plate installed inside. Therefore, the edge frame is relatively deep. In order to ensure that the upper end surface of the carrier frame 2 is not too high and the sunk groove 701 is not too deep, the depth of the sunk groove 701 can be half of the thickness of the edge frame.
[0040] In a preferred solution, a through hole is provided in the middle of the swing block 6. The chain cable joint 5 includes a connecting end block 501 and an adjusting bolt 502. The adjusting bolt 502 passes through the through hole of the swing block 6 and is threadedly connected to the connecting end block 501. The nut portion of the adjusting bolt 502 abuts against the lower end surface of the swing block 6. A locking nut 503 is also sleeved on the adjusting bolt 502, and the locking nut 503 abuts against the end of the connecting end block 501.
[0041] The adjusting bolt 502 is rotatably sleeved on the swing block 6. The length of the adjusting bolt 502 extending out and connected to the connecting end block 501 is adjustable and locked by the locking nut 503. The lengths of the lifting chain cables 3 at the four corners of the load-carrying frame 2 can be adjusted to ensure the levelness of the load-carrying frame 2.
[0042] Since the first swing arm 101 and the second swing arm 102 are of rigid structures, in order to lift the load-carrying frame 2 to a predetermined height, the top beam of the parking space base frame 4 needs to be lifted upward by a height to avoid the total height of the first swing arm 101 and the second swing arm 102, so as to prevent the upper end of the second swing arm 102 from colliding with the pulley or sprocket structure.
[0043] In a preferred solution, the lifting chain cable 3 is a round-section suspension cable. The swing block 6 is arranged near the lower end of the second swing arm 102. At least two rows of fixing clips 9 are provided near the upper end of the second swing arm 102. A clamping space for fixing the lifting chain cable 3 is provided between adjacent rows. The fixing clips 9 in each row are arranged staggeredly in the height direction, so that the fixing clips 9 are arranged in a zigzag shape as a whole. Each fixing clip 9 is provided with a groove portion 901. The groove portion 901 abuts against the outer wall of the lifting chain cable 3 to clamp the lifting chain cable 3, and the lifting chain cable 3 is pulled laterally to disengage the fixing clip 9 from the clamping space.
[0044] When the lower end of the lifting chain cable 3 approaches the pulley or sprocket structure on the top beam, the inclination degree of the lifting chain cable 3 gradually increases, and the lateral pulling force increases, pulling the lifting chain cable 3 out of the clamping space. The upper end of the second swing arm 102 is separated from the lifting chain cable 3, and the second swing arm 102 can continue to rise, so that the total height of the parking space base frame 4 will not be too high.
[0045] In a preferred solution, a plurality of through clip mounting holes 107 are provided at the upper end of the second swing arm 102. The fixing clip 9 is of a U-shaped structure. The groove portions 901 are provided on both sides of the U-shaped structure. Flanging portions 902 are provided at the ends of the U-shaped structure. The fixing clip 9 passes through the clip mounting holes 107, and the flanging portions 902 are attached to the second swing arm 102.
[0046] Threaded holes are provided around the clip mounting hole 107, and the mounting screw 903 fixes the flanging portion 902 to the second swing arm 102. The fixing clip 9 is an elastic steel sheet bent into a U-shaped structure, and groove portions 901 are bent out on both sides. Therefore, the fixing clip 9 as a whole has the ability to deform and recover, and the lifting traction cable 3 can be clamped by using the groove portions 901. Since the fixing clips 9 are staggered in height, after the lifting traction cable 3 is pulled out, the guide wheels 8 can push and separate the fixing clips 9 one by one and pass through the clamping space.
[0047] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
