Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The design concept is as follows: the purpose of conveying the rear parking spaces to the front row entrance and exit is achieved by adding the longitudinal conveying mechanism on the rear parking spaces; the lower part of the parking equipment can be made into a sunk small foundation pit, so that the non-gradient parking is realized.

Example (b):

as shown in fig. 1 to 4, the present embodiment is an arrangement type parking apparatus, including two front row parking garage racks a and two rear row parking garage racks B, the front row parking garage racks a being configured with a front row vehicle board traversing mechanism 1 and a front row vehicle board lifting mechanism 7, the rear row parking garage racks B being configured with a rear row traversing frame mechanism 3, a rear row lifting frame mechanism 5 and a longitudinal vehicle conveying plate mechanism 2; the rear row transverse frame moving mechanism 3 and the rear row lifting frame mechanism 5 are respectively provided with a longitudinal vehicle conveying plate mechanism 2, and longitudinal conveying of front and rear rows of vehicles is realized through the longitudinal vehicle conveying plate mechanism 2; foundation pits C are arranged at the bottoms of the front row parking garage frame A and the rear row parking garage frame B, the mechanisms fall in the foundation pits C and are level to the horizontal plane, and the foundation pits C are stepped foundation pits; the device also comprises a controller D for controlling the front-row vehicle plate transverse moving mechanism 1, the front-row vehicle plate lifting mechanism 7, the rear-row transverse moving frame mechanism 3, the rear-row lifting frame mechanism 5 and the longitudinal vehicle plate conveying mechanism 2 to work.

The back row of the equipment is provided with two longitudinal car feeding plate mechanisms 2 on a back row transverse moving frame mechanism 3 and three longitudinal car feeding plate mechanisms 2 on a back row lifting frame mechanism 5. The rear-row transverse moving frame mechanism 3 realizes the action of transverse moving at the rear-row position by means of a transverse moving frame transverse moving motor 4. The lifting motor 6 drives the main lifting mechanism, the main lifting mechanism drives four lifting chains, the lifting chains directly lift the rear row lifting frame mechanism 5, and the lifting and descending actions are realized on the rear row.

When the rear row transverse moving frame mechanism 3 or the rear row lifting frame mechanism 5 runs in place, when the movable longitudinal conveying guide rail 9 of the rear row transverse moving frame mechanism 3 or the rear row lifting frame mechanism 5 and the fixed longitudinal conveying guide rail 8 on the ground are in the same straight line, the switch sends a PLC signal, the PLC sends an instruction, the longitudinal conveyor 10 acts, and the longitudinal conveying plate mechanism 2 is conveyed to the corresponding position of the front row (or is moved to the rear row transverse moving frame mechanism 3 or the rear row lifting frame mechanism 5 of the rear row from the corresponding position of the front row).

The improvement of the product is as follows: 1. the front row and the rear row can be used as ladder foundation pits (the depth of the front row is 105mm, the depth of the rear row is 160mm) and can be used as whole foundation pits (the total depth is 160mm), and the civil engineering cost is saved.

2. The total depth of the foundation pit is only 160mm, and the foundation pit can be more suitable for civil engineering design and construction requirements.

3. When the movable longitudinal feeding guide rail 9 and the front row transverse moving guide rail 11 are staggered, the longitudinal feeding wheel adopts a single-side flanging mode, the phenomenon of equipment blockage caused by insufficient machining straightness of the guide rails is avoided, and meanwhile, the running noise is reduced.

More specifically:

as shown in fig. 5 and 6, the transverse moving function of the front row sweep transverse moving mechanism 1 of the present embodiment is explained: and the operation panel sends a transverse moving instruction, and the PLC receives the instruction and judges the position of the transverse moving sweep according to the in-place condition of the transverse moving in-place switch. If the conditions of the transverse moving action are met, the PLC gives an instruction to the transverse moving motor 12.

The traverse motor 12 is connected with the driving sheave 13 in a direct-coupled driving manner, and the driving sheave 13 is synchronously driven with the driving wheel 15 through the synchronous long shaft 14.

The driven sheave 16 is arranged at the rear side of the driven end, and the driven wheel 17 is arranged at the front side of the driven end. When the front row traverse motor 12 receives the instruction of the PLC and confirms that the power is switched on, the front row traverse motor starts to rotate and drives four groups of rollers to simultaneously operate, and the front row vehicle carrying board 1 can realize the action of transverse movement on the front row traverse guide rail 11. The combination of the transverse moving switch and the transverse moving in-place collision block can provide a signal for the PLC when the PLC is in the transverse moving in place, thereby completing the whole transverse moving action.

As shown in fig. 7, the lifting action of the front row bed lifting mechanism 7 is explained in detail: an instruction is sent out on the operation panel, and after the PLC receives the instruction, whether the lifting condition of the lifting vehicle plate is met is judged; if the PLC sends an instruction to the lifting motor 18, the front lifting motor 18 drives a driving chain wheel 20 through a motor chain wheel 19 assembled on an output shaft of the front lifting motor in a chain transmission mode, and the driving chain wheel 20 and two groups of driven chain wheels 21 are assembled on a lifting main shaft 26. Thus, the front row lifting motor 18 operates, and the two driven sprockets 21 synchronously operate therewith.

As shown in fig. 8, if the driven sprocket 21 rotates clockwise, the vehicle carrying board descends; otherwise, the motor rotates reversely, and the vehicle carrying plate rises. In the following figures, the first circulating chain 22, the second circulating chain 24, the lifting platform front suspension chain 23, the lifting platform rear suspension chain 25, and four chains form a closed loop, and the lifting mechanism 7 of the front row platform is lifted to complete the lifting and descending actions along with the forward and reverse actions of the driven sprocket 21.

As shown in fig. 11, the lifting principle of the rear lifting frame mechanism 5 is the same as that of the front vehicle board lifting mechanism 7, except that four lifting chains drive the lifting frame.

As shown in fig. 9 and 10, the traverse motion of the rear-row traverse frame mechanism 3 is explained in detail: the motor chain wheel 28 is assembled on the transverse moving frame transverse moving motor 4 and drives the driven chain wheel 29 through chain transmission; the driven chain wheel 29, the driving sheave 30 and the driving roller 32 are arranged on the synchronous shaft 31; the driven grooved wheel 33 is arranged at the rear side of the driven end of the rear row transverse moving frame mechanism 3, the driven roller 34 is arranged at the front side, and the stable action of the sweep can be realized by the rolling supporting wheels with four points on the same horizontal plane. The chain between the motor sprocket 28 and the driven sprocket 29 is tensioned by the adjusting screw 27.

When the PLC gives an instruction, the transverse moving frame transverse moving motor 4 is electrified and starts to rotate, and the transverse moving frame transversely moves left and right on the guide rail through four groups of rollers. When a left in-place switch 49 fixed on the traverse line pipe 46 hits the traverse collision block 47, it indicates that the rear row traverse frame mechanism 3 is in place; similarly, when the right-position switch 50 hits the traverse collision block 48, it indicates that the rear-row traverse frame mechanism 3 is in the right position. Each traverse frame is provided with 2 in-place switches. The adjacent transverse moving frames of the transverse moving collision block are shared.

Each rear row transverse moving frame mechanism 3 is provided with a movable longitudinal conveying guide rail 9, and the linearity requirements of the movable longitudinal conveying guide rail 9 on the rear row transverse moving frame mechanism 3 and a fixed longitudinal conveying guide rail 8 fixed on the ground are higher, so that the positioning requirements are strict, and actually accurate positioning cannot be realized by a switch and a transverse moving collision block in place. At this time, the accuracy of electrical control is ensured by a machine: a set of mechanical positioning rods 51 is respectively arranged on the left and right of each rear row transverse frame mechanism 3, and when the rear row transverse frame mechanisms 3 move to the electrical control position from side to side, the mechanical positioning rods 51 impact the in-place mechanical stoppers 52, so that the phenomenon of inaccurate positioning caused by inertia is solved.

As shown in fig. 12-14, the longitudinal movement is detailed: after the longitudinal conveying plate mechanism 2 reaches the corresponding rear row position along with the rear row transverse moving frame mechanism 3 or the rear row lifting frame mechanism 5, the control system gives an instruction to the longitudinal conveying motor 10, the longitudinal conveying motor 10 is electrified to rotate, and meanwhile, the locking device 42 of the locking mechanism is electrified to attract, so that the locking device 42 is prevented from being blocked when approaching the locking stop block 43. The longitudinal conveying motor 10 drives a longitudinal conveying driven sprocket 36 through a longitudinal conveying motor sprocket 35, and the longitudinal conveying driven sprocket 36 is linked with a first longitudinal conveying driving wheel 37 and a second longitudinal conveying driving wheel 40 through a longitudinal conveying transmission shaft 38. Four guide wheels of a first longitudinal conveying driven wheel 39, a second longitudinal conveying driven wheel 41, a first longitudinal conveying driving wheel 37 and a second longitudinal conveying driving wheel 40 bear the longitudinal conveying plate mechanism 2 to move from the movable longitudinal conveying guide rail 9 at the rear row to the fixed longitudinal conveying guide rail 8 at the front row.

When the longitudinal plate conveying mechanism 2 moves forwards, a longitudinal conveying position switch 54 is mounted on a longitudinal conveying switch mounting plate 53 mounted on the rear side of the longitudinal plate conveying mechanism 2, when the longitudinal conveying position switch 54 hits a longitudinal conveying position collision block 56, the position switch gives a PLC signal, and after the PLC receives the front position signal, a program judges that the longitudinal plate conveying mechanism 2 has moved in position, at the moment, the locking device 42 passes over the locking stop block 43, and the locking device is powered off, released and opened. When the vehicle enters the longitudinal conveying floor mechanism 2, the locking stopper 43 counteracts the backward impact force of the longitudinal conveying floor mechanism 2, and the longitudinal conveying limit switch 55 is mounted on the longitudinal conveying switch mounting plate 53 of the embodiment on the rear side of the longitudinal conveying position switch 54.

The power line and the signal line of the whole longitudinal plate conveying mechanism 2 are both provided by the tail part of the rear row, the form that the drag chain 45 runs in the drag chain groove 44 is adopted, and the required cable is laid in the drag chain 45. When the longitudinal board conveying mechanism 2 moves to the rear row, since the locker 42 may be caught by the locking stopper 43 and the suction force of the locker 42 itself cannot be pulled out from the locking stopper 43, it is necessary to add a slight forward longitudinal conveying action of the longitudinal board conveying mechanism 2 in the program, and the time is about 0.5 seconds. In the process from the PLC receiving the instruction of the operation panel to execute the forward micro-motion to the backward longitudinal delivery in place, the locking device 42 is in the power-on attraction state. Because the rear row transverse moving frame mechanism 3 and the rear row lifting frame mechanism 5 are arranged at the rear part of the equipment, the depth of the rear row small foundation pit is 160 mm; and the front row is the depth of a foundation pit of the common lifting and horizontal moving, namely 105 mm.

As shown in fig. 15, the controller D of the present embodiment employs a PLC control system, siemens S7-1500, to control the operations of the front-row floor traversing mechanism 1, the front-row floor elevating mechanism 7, the rear-row traversing frame mechanism 3, the rear-row elevating frame mechanism 5, and the longitudinal floor conveying mechanism 2 connected thereto. The present embodiment does not relate to the improvement of the circuit itself, and therefore, the detailed description thereof is omitted.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
