Description

Technical Field

[0001] The present invention belongs to a mechanical parking device, and in particular relates to a parking device for storing and retrieving vehicles in a comb teeth exchange manner. Background Art

[0002] Patent document CN202410274892.8 discloses a parking system with a telescopic fork-arm carrier. The carrier is equipped with two sets of fork arms, each capable of entering the corresponding comb slots of the comb beams on either side of the parking rack. Each fork arm has a fork wheel at its head and is supported by a fork crossbeam at its tail. A fork crossshaft runs through the base of each fork arm. The fork crossshaft, driven by a micro-lift mechanism within each fork arm, slightly raises and lowers the fork wheels. Simultaneously, cranks at both ends of the fork crossshaft drive the running wheels to rise and fall synchronously. The retractable fork arm assembly allows vehicles to be exchanged from the parking racks.

[0003] This prior art has the following defects:

[0004] 1. Each fork arm is equipped with four liftable fork wheels and corresponding connecting rod transmission mechanisms. Not only is the structure too complicated, but the hinge shafts in these transmission mechanisms accumulate a lot of friction resistance, resulting in the reducer output shaft still needing to provide excessive output torque even in the absence of load.

[0005] 2. The comb teeth of the car storage combing platform not only need to provide a bearing surface for the wheels, but also need to provide fork wheel running rails for the fork arms. Because a single fork arm may bear more than half the weight of the car, the material strength of each fork wheel running rail on the car storage combing platform must be very high, thus reducing the overall cost.

[0006] 3. In order for the forklift to smoothly drive into the forklift running track of the car storage combing platform, the leveling and positioning accuracy between the transporter and the car storage combing platform is required to be very high, which increases the difficulty of processing and assembly. Summary of the Invention

[0007] In order to solve the above-mentioned defects of the prior art, the present invention proposes a parking device for storing and retrieving vehicles using a carrier with a telescopic fork arm.

[0008] Its characteristics are:

[0009] The frame 1 of the carrier includes front and rear bottom rails 1211 and 1221 that are parallel to each other;

[0010] Between the front and rear bottom rails 1211 and 1221, there are two left and right transverse frames 4-1 and 4-2 that can transversely move along the front and rear bottom rails 1211 and 1221 between preset left and right limits;

[0011] A left fork tail beam 3-1 is provided between the front and rear two transverse frame guide posts 41 of the left transverse frame 4-1 and can be raised and lowered between preset upper and lower limits;

[0012] A right fork tail beam 3-2 is provided between the front and rear two transverse frame guide posts 41 of the right transverse frame 4-2 and can be raised and lowered between preset upper and lower limits;

[0013] The upper portion of the left fork tail beam 3-1 is fixedly connected to the fork arm tail 22 below the left end of a plurality of mutually parallel fork arms 2-1 cantilevered from left to right;

[0014] The upper portion of the right fork tail beam 3-2 is fixedly connected to the fork arm tails 22 below the right ends of the multiple fork arms 2-2 arranged parallel to each other and cantilevered from right to left;

[0015] The fork arm gap between the adjacent fork arms 2-1 extending from left to right and stopped at the left limit position allows the fork arms 2-2 at the corresponding position extending from right to left to pass from the right limit position to the left limit position;

[0016] The fork arm gap between the adjacent fork arms 2-2 extending from right to left and stopped at the right limit position allows the fork arm 2-1 at the corresponding position extending from left to right to pass from the left limit position to the right limit position;

[0017] The top bearing surface of the fork arm 2-1 extending from left to right and raised to the upper limit position is higher than the top bearing surface of the fork arm 2-2 extending from right to left and lowered to the lower limit position;

[0018] The top bearing surface of the fork arm 2-2 extending from right to left and raised to the upper limit position is higher than the top bearing surface of the fork arm 2-1 extending from left to right and lowered to the lower limit position;

[0019] When the left transverse frame 4-1 moves to the left limit and the right transverse frame 4-2 moves to the right limit, the top bearing surfaces of the fork arm 2-1 cantilevered from left to right and the fork arm 2-2 can alternately carry the vehicle 8 by lifting and lowering.

[0020] The utility model comprises a plurality of fixed parking combing tables 7; the parking combing tables 7 comprise a plurality of parking comb teeth 71 arranged transversely;

[0021] When the transporter stops at the transverse alignment position on the right side of a car storage combing table 7-1, the fork arm 2-2 of the transporter that moves transversely from right to left toward the car storage combing table 7-1 can enter the comb gap between the corresponding car storage comb teeth 71-1 of the car storage combing table 7-1;

[0022] When the transporter stops at the transverse alignment position on the left side of a car storage combing table 7-2, the fork arm 2-1 of the transporter that moves transversely from left to right toward the car storage combing table 7-2 can enter the comb gap between the corresponding car storage comb teeth 71-2 of the car storage combing table 7-2;

[0023] When the transporter is parked at a transverse alignment position on the side of a car storage combing platform 7, when the fork arm 2 of the transporter is raised to the upper limit position, the top bearing surface of the fork arm 2 is higher than the top bearing surface of the car storage comb teeth 71 of the car storage combing platform 7; when the fork arm 2 is lowered to the lower limit position, the top bearing surface of the fork arm 2 is lower than the top bearing surface of the car storage comb teeth 71 of the car storage combing platform 7;

[0024] The fork arm 2 of the carrier transfers the vehicle 8 between the car storage combing table 7 and the carrier through lateral movement and lifting action.

[0025] Preferably,

[0026] When the fork arm 2-2 extending from right to left is raised to the upper limit position, the top bearing surface of the fork arm 2-2 is inclined at a preset angle and gradually rises from right to left;

[0027] When the fork arm 2 - 1 cantilevered from left to right rises to the upper limit position, the top bearing surface of the fork arm 2 - 1 is in an inclined posture with a preset inclination angle, gradually rising from left to right.

[0028] Compared to existing technologies, the fork arm assembly and fork tail beam form a fully rigidly connected whole. The fork arm eliminates the complex transmission mechanism, and the fork arm head no longer requires a fork wheel assembly. This significantly simplifies the transmission mechanism, improves reliability, simplifies maintenance, and reduces costs. The car storage combing platform also eliminates the need for fork wheel tracks, significantly simplifying the structure and significantly reducing the leveling accuracy requirements.

[0029] In this article, the term "front" is Figure 17 The term "vertical" and "longitudinal" refers to the aforementioned "front-back" extension direction, and the term "horizontal" and "lateral" refers to the aforementioned "left-right" extension direction.

[0030] The above terms are only used to facilitate accurate description of the relative positional relationships of the various parts of the present invention, and are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0065] Example 1 of the present invention is as follows Figures 1 to 17 shown.

[0066] See also Figure 1 This is a schematic diagram of a parking system designed according to the principles of the present invention for storing and retrieving vehicles using a vehicle carrier with telescopic forks, showing the operation of a vehicle carrier and two left and right vehicle storage combing stations 7-1 and 7-2. The main structure of the vehicle carrier includes a frame 1, within which are mounted two left and right transverse frames 4-1 and 4-2 with combing arm assemblies.

[0067] See also Figure 2 The structure of the fork arm 2 includes a fork arm body 21 with a T-shaped cross section, and a fork arm tail 22 extending downward at the rear end of the fork arm body 21.

[0068] See also Figure 3 The fork arm tail 22 of each fork arm 2 of the fork arm group 20 for supporting the front and rear wheels of the vehicle is connected through the composite fork tail beam 3.

[0069] like Figure 4 As shown, the fork beam 3 is composed of a fork beam body 31 made of two rectangular tubes, and a fork beam end seat 34 made of double steel plates at both ends of the fork beam body 31. The fork beam end seat 34 is equipped with a fork beam top guide wheel 32 and a fork beam bottom guide wheel 33 at the upper and lower ends.

[0070] See also Figure 5 A transverse frame guide column 41 is inserted between the top guide wheel 32 of the fork tail beam and the bottom guide wheel 33 of the fork tail beam. A fork tail beam lifting drive shaft 35 driven by a motor is installed between the fork tail beam end seats 34 at the front and rear ends of the fork tail beam 3. Fork tail beam lifting eccentric wheels 51 are installed at both ends of the fork tail beam lifting drive shaft 35. The fork tail beam lifting eccentric wheel 51 is hinged to the fork tail beam lifting connecting rod shaft seat plate 43 at the lower part of the transverse frame guide column 41 via the fork tail beam lifting connecting rod 52.

[0071] The rotatable fork tail beam lifting eccentric wheel 51 drives the fork tail beam 3 and the fork arm group to rise and fall within a range of 6 cm.

[0072] A heavy-duty gas spring 53 is vertically mounted between a gas spring bottom axle seat 44, hinged to the underside of the traverse frame guide post 41, and a gas spring top axle seat 531, hinged to the upper side of the fork beam end seat 34. This gas spring 53 can offset some of the weight of the fork beam 3, the fork arm assembly, and the vehicle, creating favorable conditions for providing high efficiency with a low-power motor.

[0073] See also Figure 6 、 Figure 11 、 Figure 12 Between the front and rear sides of the traverse frame guide post 41 and the top and bottom guide wheels 32 and 33 of the fork beam, sloped guide plates 49 are provided. When the fork beam 3 is lowered to its lower limit, both the top and bottom guide wheels 32 and 33 are located at the bottom of the sloped guide plates 49. At this point, each fork arm 2 on the fork beam 3 is in a horizontal, low position. When the fork beam 3 is raised to its upper limit, both the top and bottom guide wheels 32 and 33 are located at the top of the sloped guide plates 49. At this point, each fork arm 2 on the fork beam 3 is in an inclined, high position, with its head high and its tail low.

[0074] The purpose of this design is to partially offset the deformation of the fork arm 2 caused by the inevitable material strain when the fork arm 2 is under heavy load, which causes the elastic sinking of the head of the fork arm 2, and to avoid adverse friction between the wheel and the adjacent fork arm and the parking combing table caused by excessive deformation of the fork arm 2.

[0075] See also Figure 6 The transverse frame 4 is composed of a longitudinal transverse frame top beam 47 at the top and a transverse frame guide column 41 connected below the front and rear ends of the transverse frame top beam 47. A guide column bottom guide wheel 42 is installed on the side of the bottom of the transverse frame guide column 41, and a transverse frame top chain connecting block 45 and a transverse frame bottom chain connecting block 46 are respectively provided at the top and bottom ends of the transverse frame guide column 41.

[0076] There are fork tail beam lifting link shaft seat plates 43 on the front and rear sides of the bottom of the transverse frame guide column 41. The left and right parts of the fork tail beam lifting link shaft seat plate 43 are provided with gas spring bottom shaft seats 44 for supporting the bottom end of the gas spring 53 and fork tail beam lifting link shaft holes 431 for articulating the fork tail beam lifting link 52.

[0077] See also Figure 7The carrier frame 1 includes a left front column 111, a right front column 112, a left rear column 113, and a right rear column 114; a front bottom beam 121 and a front top beam 131 connecting the bottom and top ends of the left front column 111 and the right front column 112; a rear bottom beam 122 and a rear top beam 132 connecting the bottom and top ends of the left rear column 113 and the right rear column 114; a left top beam 141 and a right top beam 142 connecting the front top beam 131 and the rear top beam 132; and a left bottom beam 151 and a right bottom beam 152 connecting the front bottom beam 121 and the rear bottom beam 122. A front bottom rail 1211 is located above the front bottom beam 121, and a rear bottom rail 1221 is located above the rear bottom beam 122.

[0078] There is a frame front guide beam 1311 below the frame front top beam 131 , and there is a frame rear guide beam 1321 below the frame rear top beam 132 .

[0079] Between the front bottom beam 121 and the rear bottom beam 122 of the frame, two left and right longitudinal chain drive shafts 17 driven by separate motors are also installed.

[0080] Chain supports 16 are installed on the lower wing plates and upper wing plates of the frame front bottom beam 121 and the frame rear bottom beam 122 made of H-shaped steel, and chain supports 16 are also installed above the frame front guide beam 1311 and the frame rear guide beam 1321.

[0081] See also Figure 8 , shown in the figure, is the state when only the right transverse frame 4-2 is installed in the frame 1. In the frame 1, the guide column bottom guide wheels 42 of the two transverse frame guide columns 41 of the left transverse frame 4-2 are installed on the front bottom rail 1211 and the rear bottom rail 1221 of the frame 1.

[0082] See also Figure 8 and Figure 10 The lower ends of the two transverse drive chains 6-2 are connected to the transverse frame bottom chain connecting blocks 46 located at the bottom ends of the two transverse frame guide columns 41, extending to the left, bypassing the transverse drive sprockets 61-2 at both ends of the chain drive shaft 17-2 used to drive the right transverse frame 4-2 to move horizontally, and then extending to the right, and then upwardly bypassing the various idle sprockets located at the upper and lower ends of the right front column 112 and the right rear column 114 of the frame, and then extending to the left and connected to the transverse frame top chain connecting blocks 45 at the top ends of the two transverse frame guide columns 41.

[0083] When the chain drive shaft 17 - 2 is driven by the drive motor to rotate, the chain drive shaft 17 - 2 will drive the right transverse moving frame 4 - 2 to move transversely along the front bottom rail 1211 and the rear bottom rail 1221 .

[0084] See also Figure 9 、 Figure 10 、 Figure 11The left transverse frame 4-1 can also be installed in the frame 1 in the same way as the right transverse frame 4-2, with a reverse offset. The guide column bottom guide wheel 42-1 of the left transverse frame 4-1 and the guide column bottom guide wheel 42-2 of the right transverse frame 4-2 share the front bottom rail 1211 and the rear bottom rail 1221.

[0085] The left transverse frame 4-1 is driven by a transverse drive chain 6-1 disposed behind the front frame bottom beam 121 and the rear frame bottom beam 122, and is laterally moved along the front bottom rail 1211 and the rear bottom rail 1221 by a chain drive shaft 17-1. This is because the fork arm group consisting of the fork arm 2-1 on the left transverse frame 4-1 and the fork arm group consisting of the fork arm 2-2 on the right transverse frame 4-2 are arranged in opposite directions.

[0086] When the right transverse moving frame 4-2 moves transversely to the left, the fork arm 2-2 on the right transverse moving frame 4-2 will penetrate into the fork arm gap next to the corresponding fork arm 2-1 on the left transverse moving frame 4-1.

[0087] Likewise, when the left transverse frame 4-1 transversely moves to the right, the fork arm 2-1 on the left transverse frame 4-1 will penetrate into the fork arm gap next to the corresponding fork arm 2-2 on the right transverse frame 4-2.

[0088] See also Figure 13 and Figure 14 The fork tail beam lifting eccentric wheel 51-1 of the left transverse frame 4-1 and the fork tail beam lifting eccentric wheel 51-2 of the right transverse frame 4-2 can rotate independently when the left transverse frame 4-1 and the right transverse frame 4-2 perform transverse movement, driving the fork arm 2-1 of the left transverse frame 4-1 and the fork arm 2-2 of the right transverse frame 4-2 to rise and fall independently, completing the operation of storing and retrieving vehicles from the vehicle storage platforms 7-1 and 7-2.

[0089] Because the one-way travel length of the fork arm may not be enough to complete the one-way storage and retrieval of the vehicle in one go, in actual operation, depending on the width of the vehicle, it may be necessary for the fork arm to stop, descend, move horizontally in the opposite direction for a short distance, and then rise in the middle of the lateral movement of the vehicle to adjust the position of the vehicle.

[0090] See also Figure 15 , Figure 16 In actual application, in order to allow vehicles to directly enter and exit the carrier, lane plate supports 181 can be set at multiple appropriate positions on the left bottom beam 151 and the right bottom beam 152 of the frame 1, and the lane plate supports 181 support multiple lane plates 18 that are roughly flush with the top bearing surface of the fork arm 2 in the lower limit position to allow vehicles to enter.

[0091] Because of the need to avoid the traverse space of the traverse frames 4-1 and 4-2 near the vehicle entrance, a gap of about 25 centimeters in width will appear at the vehicle entrance of the framework 1. For this reason, an automatically opening and closing compensation plate can be provided with the prior art to make up for this gap.

[0092] See also Figure 17 Because the width structure of the frame 1 of the carrier in the left and right directions of this embodiment overlaps with the inner end structure of the comb teeth 71-1 and 71-2 of the parking combing tables 7-1 and 7-2 as shown in A in the figure, this embodiment is only suitable for use in vertical lifting parking equipment.

[0093] In order to allow the present invention to be applied to aisle stacking and plane moving parking equipment, the present invention proposes the technical solution shown in Example 2.

[0094] Example 2 Figures 18 to 20 shown.

[0095] See also Figure 18 In this embodiment, there is a gap of several centimeters between the left and right sides of the carrier's frame 1 and the comb-teeth ends of the left and right parking platforms 7-1 and 7-2. This allows the carrier to be loaded into a stacker in a laneway-stacking parking system, allowing it to rise and fall with the stacker, allowing vehicles to be stored and retrieved from the multi-layer, multi-row parking platforms on both sides of the laneway.

[0096] See also Figure 19 and Figure 20 In this embodiment, a screw rod 191 transmission mechanism is used to drive the two transverse frames to perform transverse movement.

[0097] Obviously, in addition to the screw mechanism arranged on the upper part of the frame 1 shown in the figure, a screw transmission mechanism is also arranged in the front bottom beam 121 and the rear bottom beam 122 of the frame to drive the transverse movement of the transverse frame.

[0098] In a specific application, when the frame 1 does not require a vehicle to drive directly into, the transmission mechanism can be set between the left front column 111 and the right front column 112 of the frame, and between the left rear column 113 and the right rear column 114 of the frame.

[0099] In addition to the eccentric wheel solution in Example 1, the lifting and lowering of the fork tail beam can also adopt various transmission mechanisms in the prior art, such as electric push rods, hydraulic push rods, crank rockers, gear racks, etc. Similarly, the lateral movement of the traverse frame can also be achieved using various other transmission mechanisms.
