DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the protection scope of the utility model.

[0023] In the description of the utility model, it is necessary to explain that unless there is explicit provision and limitation, the terms "mount", "connect", "connection" should be understood broadly, for example, can be fixed connection, also can be detachable connection, or integrally connected;Can be mechanical connection, also can be electrical connection;Also can be directly connected, also can be indirectly connected through intermediate medium, can be the intercommunication of two elements. For the ordinary skill in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0024] Example 1:

[0025] This embodiment provides an intelligent stacker crane for a digital warehousing system, specifically as follows: Figures 1-4 As shown, the device includes a moving track 101, a column 102, and a fork assembly. The column 102 is slidably connected to the moving track 101, and the fork assembly is slidably connected to the column 102. The fork assembly includes a base, a fork portion, and a drive portion. The fork portion and the drive portion are both mounted on the base, which is slidably connected to the column 102. The drive portion is drively connected to the fork portion. The base also includes a limiting portion, which is used to cut off the power transmission between the drive portion and the fork portion and limit the fork portion when the fork portion moves to the limit position.

[0026] In use, the drive column 102 moves laterally along the moving track 101 with the fork assembly. After moving to the predetermined position, the column 102 stops moving. At this time, the drive fork assembly moves longitudinally along the column 102 until it moves to the position where the goods need to be stacked. At this time, the drive unit causes the forks to extend and place the goods on the shelf.

[0027] If, due to operational errors, inaccurate control, or load variations, the fork reaches its limit position while the drive unit continues to output power, the limit unit cuts off the power transmission between the drive unit and the fork to prevent the fork from directly impacting the limiting part or detaching from the base. This deprives the fork of its power source and limits its movement. In other words, this design prevents the fork from rigidly impacting the limiting part or detaching from the track after storing goods at its limit position, effectively improving the stability of the fork assembly.

[0028] Example 2:

[0029] This embodiment further extends the above embodiment, specifically as follows: Figures 2-6As shown, the fork part comprises a pushing fork seat 206, a first pushing fork 205 slidingly connected on the pushing fork seat 206, and the pushing fork seat 206 is installed on the base; the driving part comprises a driving unit and a transmission unit, the transmission unit comprises a chain 209 and two sprockets 208 rotatably connected on the pushing fork seat 206, the chain 209 is sleeved on the two sprockets 208, and a pushing block 215 is installed on the chain 209; a moving column 207 is installed on the first pushing fork 205, a power linkage unit is installed on the moving column 207, and the pushing block 215 transmits power to the moving column 207 through the power linkage unit. The power linkage unit comprises a stop lever set 217 rotatably connected on the moving column 207 and a double-headed inclined block 219, a torsional spring is arranged at the connection between the double-headed inclined block 219 and the moving column 207, a clutch block 216 is fixedly connected on the double-headed inclined block 219, a push rod 218 is installed on the clutch block 216, the push rod 218 cooperates with the stop lever set 217, the clutch block 216 cooperates with the pushing block 215, two limiting rods 210 are installed on the clutch block 216, and inclined surfaces are arranged at both ends of the double-headed inclined block 219. The limiting rods 210 cooperate with the inclined surfaces of the double-headed inclined block 219.

[0030] When the driving unit starts to transmit power to the sprocket 208, the sprocket 208 drives the chain 209 to move, at this time, the chain 209 drives the pushing block 215 on it to move, the pushing block 215 pushes the clutch block 216, at this time, because one side of the stop lever set 217 limits the push rod 218, the clutch block 216 cannot rotate, and then the pushing block 215 drives the moving column 207 to start synchronous horizontal movement through the clutch block 216, at this time, the first pushing fork 205 starts to move the goods out of the placement. When the first pushing fork 205 moves to the limit position, if the driving unit does not stop running as expected, then one side of the limiting rod 210 will abut against one side of the inclined surface of the double-headed inclined block 219, at this time, the double-headed inclined block 219 is rotated by the rotating force and starts to rotate, the torsional spring is deformed under the force, until the push rod 218 rotates to the other side of the stop lever set 217 and is blocked, at this time, the clutch block 216 cannot block the movement of the pushing block 215 due to the rotation, the pushing block 215 continues to move along with the chain 209 after passing through the clutch block 216, at this time, the torsional spring resets, and the moving column 207 is no longer subjected to the pushing force, that is, the fork part will not directly and rigidly impact the limiting rod 210, thereby avoiding the derailment of the fork part.

[0031] Preferably, the limiting rod 210 is provided with a thread, and the limiting rod 210 is threadedly connected with the pushing fork seat 206. By rotating the limiting rod 210, the limiting rod 210 moves horizontally on the pushing fork seat 206, thereby adjusting the power disconnection position of the fork part and the transmission unit to adapt to different scenes.

[0032] Further, the driving unit comprises a driving motor 204 and a speed reducer 214 mounted on the base, the output end of the driving motor 204 is connected with the input end of the speed reducer 214, and the output end of the speed reducer 214 is connected with the chain wheel 208. The power output by the driving motor 204 is transmitted to the chain wheel 208 after being reduced by the speed reducer 214.

[0037] In the embodiment, the goods are placed on the second push fork 202, when the first push fork 205 moves to one side, the pulley 211 is synchronously moved, because the length of the steel cable 212 is fixed and the push fork seat 206 does not move, the steel cable 212 pulls the second push fork 202 to move, and the moving distance of the second push fork 202 is twice that of the first push fork 205, so that the length of the goods pushing is extended; when the first push fork 205 moves reversely, the same principle can be obtained.
