Description

Technical Field

[0001] The invention belongs to parking equipment for storing multiple vehicles, and in particular to parking equipment equipped with a telescopic fork arm type transporter. Background Art

[0002] In Chinese patent CN201810749060.1, a parking device with a carrier with a telescopic fork arm is disclosed. In this scheme, a fixed long fork arm with an opening facing the carrier is provided on the storage rack, and a retractable long fork arm facing the storage rack is provided on the liftable carrier. During operation, the retractable long fork arm enters the fork gap of the fixed long fork arm, and uses a micro-lifting mechanism to store and retrieve the load from the storage rack.

[0003] This solution has the following drawbacks:

[0004] 1. Its retractable long fork arm is a strip-shaped component with a one-way cantilever length of more than two meters. When transmitting heavy loads such as automobiles, its root is subjected to great force, which places high demands on the material's resistance to deformation and fracture, and is not conducive to low-cost manufacturing.

[0005] 2. In order to adapt to the wheel diameter, the width of the telescopic long fork arm of the transporter should generally be set to about 5 cm, and the tooth gap width should generally be set to about 10 cm. Under this size, when the end of the long fork arm is squeezed by the wheel tire at the tooth gap position, it is easy to produce a large lateral bending deformation, which is easy to cause a tooth collision failure.

[0006] 3. The same set of telescopic forks with fixed telescopic directions cannot meet the requirements of vehicle access to the storage racks arranged opposite to each other on both sides of the hoistway. Even if two upper and lower transporters are arranged in the hoistway to meet the requirements of the storage racks in opposite directions, the same transporter cannot transfer the vehicle on the storage rack on one side to the storage rack on the other side.

[0007] 4. The solution does not explain how to ensure that the telescopic comb teeth remain balanced when moving laterally. The key point of the technology is to keep the extra-long telescopic comb teeth from tilting and tipping during telescopic operation. However, the technical solution required to achieve this requirement is not easy to deduce from the description of the solution. Summary of the invention

[0008] In order to solve the above-mentioned defects of the prior art, the present invention proposes a parking device with a telescopic fork arm carrier, which is characterized by:

[0009] The carrier 2 is equipped with a fork arm assembly, which includes a plurality of fork arms 1 arranged longitudinally;

[0010] The front end of the fork arm 1 is provided with a fork wheel 151, and driven by a micro-lifting mechanism disposed in the fork arm 1, the fork wheel 151 can be raised or lowered slightly;

[0011] There is a fork arm gap between adjacent fork arms 1;

[0012] The fork arm assembly includes a fork tail crossbeam 3;

[0013] The lower rear end of each fork arm 1 is mounted on the fork tail crossbeam 3;

[0014] The fork tail cross beam 3 is arranged between the front and rear carrier cross beams 21;

[0015] Driven by the micro-lift mechanism, the tail of each fork arm 1 and the fork wheel 151 rise and fall synchronously, and drive each fork arm 1 to rise and fall synchronously;

[0016] The fork tail cross beam 3 can be longitudinally translated between the front and rear carrier side beams 21 under the drive of the longitudinal movement mechanism;

[0017] The fork wheel 151 of the fork arm 1 which has retreated to the rear limit position is supported by a fork wheel support platform arranged on the carrier cross beam 21;

[0018] It includes a plurality of fixed storage racks 8;

[0019] The car storage rack 8 includes car storage comb beams 83 arranged longitudinally, and a combing rail 84 is provided at the bottom of the combing gap between adjacent car storage comb beams 83;

[0020] When the carrier 2 is aligned with a storage rack 8 longitudinally, the fork tail beam 3 moving forward can drive the fork wheels 151 of each fork arm 1 from the fork wheel support platform 23 of the carrier 2 into the corresponding combing rail 84 of the storage rack 8;

[0021] When the fork arm 1 is raised to the upper limit position, the top surface of the fork arm 1 is higher than the top surface of the parking comb beam 83 , and when the fork arm 1 is lowered to the lower limit position, the top surface of the fork arm 1 is lower than the top surface of the parking comb beam 83 .

[0022] Since the fork wheel 151 that can move on the combing rail 84 is arranged under the head of the fork arm 1, the fork arm 1 can smoothly enter the combing groove of the parking comb beam 83 when bearing the vehicle load, and the overall force of the fork arm is balanced. Therefore, the fork arm 1 body does not need to use high-performance materials, and the structural dimensions do not need to be excessively increased, which is conducive to low-cost manufacturing. In addition, since the two ends of the fork arm 1 are constrained by the combing rail 84 during operation, it is not easy to deviate or shift sideways even when the wheel is under heavy pressure.

[0023] Preferably,

[0024] Including a fork tail cross axis 4;

[0025] The fork tail transverse axis 4 passes through the fork tail transverse axis hole 114 at the tail of each fork arm 1;

[0031] The pry bar fixing shaft 1611 in the middle of the fork pry bar 161 is hinged to the fork pry bar shaft hole 141 at the head of the fork arm 1;

[0032] The upper swing shafts 1612 of the front and rear fork pry bars 161 are hinged to the front and rear end holes of the pry bar upper connecting rod 162;

[0033] The front end of the fork arm long connecting rod 163 in the fork arm 1 is connected to the upper connecting rod 162 of the pry bar, and the rear end is hinged to the upper swing shaft 1652 of the fork tail three-hole swing plate 165 at the tail of the fork arm 1;

[0034] The fixed shaft 1651 of the three-hole swing plate 165 at the fork tail is hinged to the side plate at the tail of the fork arm 1;

[0040] Preferably,

[0041] A longitudinal guide rail 24 is provided between the front and rear cross beams 21 of the carrier 2;

[0042] Both ends of the fork tail horizontal axis 4 are connected to the walking wheel 5 via a crank 41;

[0043] The traveling wheel 5 is driven by the longitudinal movement mechanism to translate along the longitudinal guide rail 24;

[0044] When the fork wheel frame 15 is lowered to the lower limit position, the travel wheel 5 is lowered to the lower limit position by the crank 41;

[0045] When the fork wheel frame 15 is raised to the upper limit position, the travel wheel 5 is raised to the upper limit position by the crank 41 .

[0046] The above preferred solution of the present invention enables the micro-lifting action of each fork arm 1 to be completed via the same fork tail horizontal axis 4 driven by the micro-lifting mechanism, thereby simplifying the electromechanical system and providing conditions for further reducing the cost.

[0050] The storage rack 8 includes a forward storage rack 8_1 and a reverse storage rack 8_2, and the carrier 2_b moves between the storage rack 8_1 and the reverse storage rack 8_2;

[0051] When the carrier 2_b is aligned with the reverse storage rack 8_2 longitudinally, the fork tail cross beam 3_2 of the second fork arm group that moves backwards can drive each fork arm 1_2 of the second fork arm group to enter the corresponding combing gap of the reverse storage rack 8_2.

[0052] Preferably,

[0053] The running wheel 5_1 of the first fork arm group and the running wheel 5_2 of the second fork arm group share the longitudinal guide rail 24;

[0054] The fork arm group is divided into a left fork arm group and a right fork arm group, and between the left fork arm group and the right fork arm group, two left and right first drive chains 61_1 and two left and right second drive chains 61_2 are provided;

[0059] The above preferred solution of the present invention realizes that two sets of fork arm groups with opposite working directions are arranged on the same transporter, so as to achieve the purpose of using one transporter to handle the storage racks arranged on both sides of the working area. In addition, under the coordinated action of the two sets of fork arm groups, the vehicles on the storage rack on one side can be easily transferred to the storage rack on the other side.

Two fork wheels 151 are installed between the left and right fork wheel frame side plates 152; The rear portion and the middle portion of the fork wheel frame side plates 152 have two pairs of fork wheel frame pry bar shaft holes 153.

[0122] See also Figure 5 , Figure 6 , Figure 7 , Figure 8 The fork wheel frame pry rod shaft holes 153 at the rear and middle parts of the fork wheel frame 15 are respectively hinged to the lower swing shafts 1613 of the two fork head pry rods 161; the pry rod fixing shaft 1611 at the middle part of the fork head pry rod 161 is hinged to the fork head pry rod shaft hole 141 at the head part of the fork arm 1;

[0123] The upper swing shafts 1612 of the front and rear fork pry bars 161 are hinged to the front and rear end holes of the pry bar upper connecting rod 162;

[0124] The front end of the fork arm long connecting rod 163 in the fork arm 1 is hinged to the upper swing shaft 1612 of the pry bar upper connecting rod 162, and the rear end is hinged to the upper swing shaft 1652 of the fork tail three-hole swing plate 165 at the tail of the fork arm 1;

[0125] The fixed shaft 1651 of the fork tail three-hole swing plate 165 is hinged to the fork tail swing rod shaft hole 142 at the tail of the fork arm 1;

[0129] The center line of the three holes of the fork tail three-hole swing plate 165 forms an angle of 80°.

[0130] See also Fig. 9 , Fig.10 The fork tail support plate 131 of each fork arm 1 is fixedly installed in the steel groove structure of the fork tail cross beam 3; the fork tail cross axis 4 passes through the fork tail cross axis hole 114 at the tail of each fork arm 1 and the driving axis hole 1671 of the fork tail driving swing rod. The fork tail cross axis 4 and the fork tail driving swing rod 167 are fixedly connected with the fork tail driving swing rod 167 by means of a key pin or a special-shaped hole structure.

[0131] Both ends of the fork tail transverse axis 4 are hinged to two grooved running wheels 5 via a crank 41 with an arm length of 39 mm.

[0132] The fork tail horizontal axis 4 is installed in the steel groove type fork tail cross beam 3 and is driven by the reduction motor of the micro-lift mechanism to make a 77° reciprocating rotation. Figure 5 , Figure 6 When the fork lever 161 rotates counterclockwise to the limit angle, the above-mentioned connecting rod mechanism will drive the fork lever 161 to rotate counterclockwise to the limit angle. At this time, the lower swing axis 1613 of the fork lever 161 is located directly below the lever fixed axis 1611, and the upper swing axis 1612 of the lever is located above and behind the lever fixed axis 1611. The fork wheel 151 and the walking wheel 5 are as shown in FIG. Fig.10 As shown, they are all lowered to the lower limit position, so that the top surface of the fork arm 1 rises to the upper limit position.

[0134] Since the center distance between the hole of the pry bar fixing axis 1611 of the fork head pry bar 161 and the pry bar lower swing axis 1613 is 3 cm, the lifting range of the fork arm 1 is 3 cm.

[0135] A base frame for mounting only one set of fork arms 1 on a carrier 2 is shown in FIG. Fig.11 As shown, it is a steel structure frame surrounded by front and rear cross beams 21 and left and right longitudinal beams 22. Between the front and rear cross beams 21, there are two left and right longitudinal guide rails 24 and two left and right drive chain base beams 64. The left and right toothed fork wheel support platforms 23 are installed on the front cross beam 21. The drive chain 61 is installed on the drive chain base beam 64.

The grooved wheel type running wheels 5 at both ends of the fork tail beam 3 are installed on the rail surface of the longitudinal guide rail 24. The two traction bases 31 fixedly installed in the middle of the fork tail beam 3 are connected to the chain links of the drive chain 61 through two swing arm type fork arm traction arms 7. The driving sprockets 62 of the left and right driving chains 61 are rigidly connected to the sprocket drive shaft 65.

[0137] The structure of the storage rack 8 of the present embodiment is as follows Fig.13 As shown, the structure includes a car storage comb beam 83 installed above the front cross beam 82 and the rear cross beam 81, and a combing gap bottom rail 84 located at the bottom of the combing gap between adjacent car storage comb beams 83.

[0138] See also Fig.14 , Fig.15 When the carrier 2 and the storage rack 8 are longitudinally aligned, the combing bottom rails 84 between the storage comb beams 83 at the corresponding positions of each fork arm 1 and the storage rack 8 are longitudinally aligned. Fig.16 As shown, the drive chain can drive the fork tail cross beam 3 to move toward the storage frame 8, so that the fork wheel 151 at the head of the fork arm 1 enters the combing gap of the storage comb beam 83 along the combing gap bottom rail 84, and finally Fig.17 As shown, the fork arm 1 completely enters the combing gap of the parking comb beam 83. Figures 15 to 17 The fork arm 1 is shown in the state of being lowered to the lower limit position, and its fork cover plate 11 is lower than the top surface of the storage comb beam 83, and the drop is about 1.5 cm. Fig.18 and Fig.19 As shown, if a vehicle 9 is parked on the storage rack 8 at this time, the fork cover plate 11 will not scrape the wheel of the vehicle 9 during the process of the fork arm 1 entering the bottom of the vehicle 9. Afterwards, the micro-lifting mechanism drives the fork tail horizontal axis 4 to rotate, driving each fork arm 1 to rise by 3 cm. Fig. 20 As shown, the wheel 91 of the vehicle 9 is lifted instead of the storage comb beam 83. At this time, the fork cover plate 11 of the fork arm 1 is higher than the storage number 83 by about 1.5 centimeters.

[0139] See also Fig.21 Because the two ends of the fork arm traction arm 7 are respectively hinged with the traction base 31 of the fork tail beam 3 and the chain links of the drive chain 61, when the fork arm 1 is raised and lowered within a range of 3 cm, the fork arm traction arm 7 will always maintain the longitudinal traction state of the fork arm group, and will not produce obvious longitudinal displacement deviation.

[0140] See also Fig. 22 When the fork arm 1 rises to the upper limit position, the cranks 41 at both ends of the fork tail horizontal axis 4 and the lower arm sections of the fork head pry rods 161 of the fork wheel frame 15 are in a vertical posture. This posture is obviously an ideal working condition for coping with heavy load pressure, and will not transmit large torque to the main shaft of the reduction motor, avoiding undesirable height changes of the fork arm 1 when moving.

[0141] Figures 1 to 22 The application mode described here is to arrange only one set of mobile fork arms in the carrier 2, which can be used in practical environments with limited space or other purposes, such as "single-sided stacking" projects, or vertical lift warehouse projects where multi-layer storage racks 8 can only be arranged on one side.

[0142] In fact, this embodiment can be Fig.23 As shown, a first fork arm group and a second fork arm group in opposite directions are arranged between the same pair of longitudinal guide rails 24. The fork arms 1_1 of the first fork arm group and the fork arms 1_2 of the second fork arm group are arranged alternately and head and tail directions are opposite; each fork arm 1_1 of the first fork arm group and each fork arm 1_2 of the second fork arm group are arranged alternately and interlaced with each other, and one fork arm of one group is located in the corresponding fork gap of the other fork arm group. Fig.24 As shown, the carrier 2_b suitable for arranging two sets of fork arm groups also provides two sets of integrated drive chains 61_1, 61_2 for the fork arm groups with different moving directions. A pair of fork wheel support platforms 23_1, 23_2 are arranged on the two side beams 21_1, 21_2 of the carrier. The running wheel 5_1 of the first fork arm group and the running wheel 5_2 of the second fork arm group share the longitudinal guide rail 24 in the carrier.

[0143] See also Fig.25 Each fork arm group is divided into a left fork arm group and a right fork arm group, and between the left fork arm group and the right fork arm group, there are two left and right first drive chains 61_1 and two left and right second drive chains 61_2;

[0144] The first driving chain 61_1 is connected to the fork tail beam 3_1 of the first fork arm group by means of the first fork arm traction arm 7_1, and the second driving chain 61_2 is connected to the fork tail beam 3_2 of the second fork arm group by means of the second fork arm traction arm 7_2;

[0145] The driving shaft 65_1 of the first driving chain is installed on the rear crossbeam 21_1 of the carrier, and the driving shaft 65_2 of the second driving chain 61_2 is installed on the front crossbeam 21_2 of the carrier;

[0146] The driving sprocket 62_1 of the first driving chain 61_1 is rigidly connected to the driving shaft 65_1 of the first driving chain, and the driving sprocket 62_2 of the second driving chain 61_2 is rigidly connected to the driving shaft 65_2 of the second driving chain;

[0147] The idle sprocket 63_1 of the first drive chain 61_1 is hinged to the drive shaft 65_2 of the second drive chain, and the idle sprocket 63_2 of the second drive chain 61_2 is hinged to the drive shaft 65_1 of the first drive chain.

[0148] After being connected in this way, the two left and right first drive chains 61_1 and the two left and right second drive chains 61_2 can be driven by different longitudinal drive motors respectively and operate independently of each other.

[0149] See also Fig.26 , Fig. 27 The carrier 2_b equipped with two sets of fork arm groups can move between the storage rack 8_1 and the reverse storage rack 8_2.

[0150] In this embodiment, the pitch of the fork arm and the storage comb beam is 145 mm. Therefore, in order to allow the carrier 2_b to align the forward storage rack 8_1 and the reverse storage rack 8_2 at the same time, the storage comb beam 83_1 of the forward storage rack 8_1 and the storage comb beam 83_2 of the reverse storage rack 8_2 need to be arranged in a transverse staggered manner, and the staggered distance is about 72 mm.

[0151] See also Fig.28 When the carrier 2_b is aligned longitudinally with the reverse storage rack 8_2, the fork tail beam 3_2 driven by the second drive chain 61_2 to translate backward can drive each fork arm 1_2 of the second fork arm group to enter the combing gap of the corresponding storage comb beam 83_2 of the reverse storage rack 8_2.

[0152] See also Fig.29 , the components of the first fork arm group and the second fork arm group arranged in an opposite and staggered manner can operate independently without interfering with each other. When the second fork arm group completely enters the reverse storage rack 8_2, the fork tail cross beam 3_2 of the second fork arm group and the fork tail cross beam 3_1 of the first fork arm group are close to each other, but the respective running wheels 5_2, 5_1 can still operate and perform lifting actions independently without interfering with each other.

[0153] See also Fig.25 , after the first fork arm group and the second fork arm group are both returned to the carrier 2_b, the two fork arm groups can still perform independent lifting and lowering actions, and can perform small longitudinal movements within a few centimeters. This function can be used to adjust the longitudinal position deviation of the wheels alternately lifted by the two fork arms, and play a role in correcting and centering the vehicle. When it is necessary to move the vehicle on the carrier 2_b to a storage rack on one side, it is only necessary to lift the corresponding set of fork arm groups by 3 cm, independently lift the vehicle and move it to the required idle storage rack. This function can easily take out the vehicle in the storage rack on one side and transfer it to the storage rack on the other side. It can also be at the entrance of the garage, first send the vehicle to be shipped out of the carrier to the special comb beam in the car picking area, and then collect a vehicle to be stored in the storage area, so that the garage can operate efficiently.

[0154] In order to simplify the processing technology, reduce the material consumption and reduce the cost, the storage comb beam of the storage rack in this embodiment can be as follows Fig.30 , Fig.31 As shown, a bent plate type car storage comb beam 831 is used which can be assembled and fastened to each other.

[0155] The cross-sectional structure of this bending plate type car storage comb beam 831 is as follows Fig.32 As shown, it includes a first vertical plate 8311 located at the upper left part, a first horizontal plate 8312 extending to the right and connected to the top edge of the first vertical plate 8311, a second vertical plate 8313 extending downward and connected to the right side of the first horizontal plate 8312, a second horizontal plate 8314 extending to the right and connected to the bottom edge of the second vertical plate 8313, an inclined plate 8315 extending to the upper right and connected to the right side of the second horizontal plate 8314, a third vertical plate 8317 extending upward and connected to the top edge of the inclined plate 8315, and a third horizontal plate 8317 extending to the left and connected to the top edge of the third vertical plate 8317.

[0156] The height of the bent plate type car storage comb beam 831 is greater than the height of the fork arm 1. In this embodiment, the value is 122 mm;

[0157] See also Fig.33 When multiple bending plate type car storage comb beams 831 are interlocked and arranged, the right side of the third vertical plate 8316 of the bending plate type car storage comb beam 831 is in contact with the left side of the second vertical plate 8313 of the adjacent bending plate type car storage comb beam 831 on the right side; in this embodiment, the recommended horizontal spacing between the second vertical plate 8313 of the bending plate type car storage comb beam 831 and the first vertical plate 8311 of the adjacent bending plate type car storage comb beam 831 on the right side is 95mm.

[0158] The second transverse plate 8314 of the bent plate type car storage comb beam 831 serves as the combing seam bottom rail 84 .

[0159] The purpose of the third transverse plate 8317 of the bent plate type car storage comb beam 831 is only to enhance the bearing capacity of the first transverse plate 8312. When the material thickness and material properties allow, the third transverse plate 8317 can be omitted.

[0160] In this embodiment, the slope of the inclined plate 8315 is 60°. The inclined plate 8315 can significantly increase the anti-extrusion deformation capability of the second vertical plate 8313.

[0161] It is obvious that the connecting rod transmission mechanism in the fork arm 1 of this embodiment can be replaced by other transmission mechanisms in the prior art in actual application, and the purpose of slightly lifting and lowering the fork arm as a whole can be achieved. For example, a transmission mechanism including a gear rack, a hydraulic transmission mechanism, a transmission mechanism including a screw rod, a transmission mechanism including a cam, a transmission mechanism including a chain, etc. The connecting rod mechanism proposed in this embodiment may have the advantages of being relatively simpler and easier to implement.

[0162] Similarly, the lifting and longitudinal movement of the fork tail beam in this embodiment can also be completed by the transmission mechanism in the prior art as described above. However, the crank mechanism and integrated drive chain mechanism in this embodiment may have the advantages of being simpler and easier to implement.
