Example 1

The power-off car pick-up device of the vertical cycle parking garage shown in Figure 1-8 includes a frame 1, a drive motor 21 with a brake release lever 23, and a manual drive device;

The manual driving device includes a manual clutch 22 drivingly connected to the output shaft of the drive motor 21, a worm gear reducer 51 with a rocker 54 for manual output power, connected to the input end of the manual clutch 22 and the output of the worm gear reducer 51 The transmission mechanism 4 at the end, and the first drive mechanism for driving the manual clutch 22.

The first driving mechanism includes a first flexible cable 24 connected to the manual clutch 22 , and a first control lever 522 connected to the other end of the first flexible cable 24 . The first flexible cable 24 is guided by at least one fixed pulley 521, and obviously other guiding structures, such as runners, can also be used. The first flexible cable 24 can be a steel wire rope, a nylon rope or a fiber rope or the like.

The manual clutch 22 includes a housing 228, a flywheel 221 arranged at the end of the output shaft of the drive motor 21, a sliding guide arranged at the gear sleeve 227 at the output end of the transmission mechanism 4, and a gear sleeve 227 arranged at the end of the gear sleeve 227 to cooperate with the flywheel 221. The friction plate 222, the swing rod 226 whose rod is hinged with the housing 228, one end in contact with the gear sleeve 227, the bracket 224 arranged on the housing 228, and the spring 225 connected with the bracket 224 and the swing rod 226 at both ends; When the first driving mechanism is in the working state, the swing rod 226 swings and drives the gear sleeve 227 to approach the flywheel 221, and drives the friction plate 222 to frictionally engage with the flywheel 221; when the first driving mechanism is in the non-working state, the swing rod 226 Reset under the action of the spring 225, the friction plate 222 is separated from the flywheel 221. The gear sleeve 227 is provided with a groove for the end of the swing rod 226 to extend into. The depth of the groove should ensure that the swing rod 226 does not escape from the groove within the working range; in order to reduce wear and tear, the swing rod 226 and the gear sleeve The connecting end of the barrel 227 is provided with a movable wheel 223 . The movable wheel 223 is located on the gear sleeve 227 on which the friction plate 222 is installed, and the inner wall surface of the side of the gear sleeve 227 connected with the transmission mechanism 4 is a straight tooth internal tooth structure. The side of the transmission mechanism 4 connected to the gear sleeve 227 is a straight tooth external tooth structure, and the internal and external teeth can mesh with each other. When the shaft system is not rotating, the relative movement between the internal and external teeth can be realized, so that the friction plate 222 and the flywheel 221 are frictionally engaged to transmit rotational torque, and the meshing width of the inner teeth of the sleeve and the external teeth of the shaft end is larger than that of the friction plate 222 and the flywheel The distance between 221.

The manual clutch 22 is normally in the disconnected state, that is, the swing lever 226 is in the open (reset) state, so that the transmission mechanism 4 and the output shaft of the driving motor 21 are not connected. In the normal power-on state, if the manual clutch 22 is in the closed state, that is, the transmission mechanism 4 and the output shaft of the drive motor 21 are in a connected state, the system will prompt a fault to avoid overloading the drive motor 21 due to the self-locking function of the worm gear. .

The transmission mechanism 4 includes a horizontal shaft 42 connected to the input end of the manual clutch 22, a vertical shaft 41 connected to the output end of the worm gear reducer 51, and a bevel gear reversing device 3 connecting the horizontal shaft 42 and the pivot shaft.

The worm gear reducer 51 includes a housing 514, which is rotatably arranged on the housing 514, on which a worm gear 511 is arranged and a turbine shaft 513 connected to the vertical shaft 41, and which is rotatably arranged on the housing 514, on which a crank handle 54 is arranged. And the worm 512 meshed with the worm gear 511; the worm 512 is installed on the housing 514 through the bearing 5121; while the worm gear reducer 51 achieves the reversing function, it can also use the self-locking function of the worm gear 511 and the worm 512, which will not be driven by the transmission. The rotation of the mechanism 4 drives the crank handle 54 to rotate, that is, the rotation power will not be reversely transmitted, ensuring the safety of the vehicle.

As a further improvement, it also includes a second driving mechanism for driving the brake release lever 23, the structure of the second driving mechanism is the same as that of the first driving mechanism. The second driving mechanism includes a second flexible cable 61 connected to the brake release lever 23 , and a second operating rod 62 connected to the other end of the second flexible cable 61 . Under normal power-on conditions, the drive motor 21 can realize electric braking and braking release. When a power failure requires a manual car removal operation, pull the second joystick to the direction of loosening the brake and drive the brake release lever 23 to act, and the drive motor 21 brake is manually released. After getting the car, pull the second joystick to the direction of tightening the brake, and the brake release lever 23 resets the drive motor 21 and the brake is locked. The second driving mechanism can further reduce operation difficulty and improve operation efficiency.

In this embodiment, the connection between the shafts and the rods is preferably connected by a coupling, and of course other connection methods can also be used for connection. For example, the connection between the first connecting shaft 35 and the horizontal shaft 42 , the connection between the second connecting shaft 36 and the vertical shaft 41 , and the connection between the turbine shaft 513 and the vertical shaft 41 are all connected by couplings.

In this embodiment, the drive motor 21 has a double output shaft structure, one output shaft is connected to the reduction box for driving under normal use conditions, and the other output shaft is connected to a coupling for power failure. The manual pick-up mode is used.

When a power failure requires manual car removal, use the first joystick 522 to connect the transmission mechanism 4 mounted on the frame 1 with the output shaft of the drive motor 21, and then use the second joystick to release the brake of the drive motor 21 , by manually shaking the crank handle 54, the vehicle can be moved from the parking space of the vertical circulation parking garage to the entrance and exit of the parking passage. The rod 522 disconnects the transmission mechanism 4 and the output shaft of the drive motor 21 .
