The automatic stereoscopic warehouse can effectively improve the space utilization rate of the warehouse and the automation degree of warehouse operation. The tunnel type stacker is used as goods hoisting equipment of an automatic vertical warehouse, shuttles in a warehouse tunnel to operate, and automatically takes out formulated goods from a goods shelf or places the formulated goods into a specified goods grid according to a dispatching system instruction.

In the related scheme, the roadway stacker comprises a base, a stand column, a control cabinet, a cargo carrying platform, a hoisting mechanism and the like. The base comprises a driving unit which can drive the whole machine to reciprocate on the ground rail along the roadway direction. The hoisting mechanism drives the cargo carrying platform to reciprocate along the vertical direction by adopting a hoisting mechanism. The cargo carrying platform is provided with a cargo fork device to realize the storage and taking functions of cargos. The stacker can be divided into a single-column stacker and a double-column stacker according to the difference of the mechanical structural forms.

The height value of the ground of the first layer of goods shelves is particularly critical when the elevated vertical warehouse is designed. Because the height of each layer of the shelf is fixed, if the height of the first layer of the shelf from the ground is too high, the number of the layers of the shelf is lost, and the total inventory is greatly reduced. The lower the height of the first-layer shelf from the ground, the higher the space utilization rate in the height direction, the more layers of goods can be placed, and the larger the total inventory of the shelf is. The height of the first layer of goods shelf from the ground is determined by the matching design of the base of the stacker, the upright post and the goods carrying platform.

In a related scheme, the top surfaces and the bottom surfaces of a cross beam of a base of the stacker, a driving wheel bracket and a driven wheel bracket are flush. The height of the upright post fixedly arranged on the cross beam can not be further reduced, and further the lowest descending height of the cargo carrying platform lifted along the upright post can not be further reduced.

In order to solve the technical problem, the application provides a stacker, and the stacker can further reduce the height to which the goods carrying platform is lowest, so that the height of the first layer of the goods shelf can be further reduced, and the inventory of the goods shelf is further improved.

Referring to fig. 1 and 2, the embodiment of the present application provides a stacker, which includes a base 1, a driving device 2, a column 3, a cargo bed 4, a lifting device (not shown in the figure), and a control cabinet (not shown in the figure).

Referring to fig. 3 and 4, the base 1 includes a driving wheel bracket 11, a driven wheel bracket 12, and a cross member 13.

A drive wheel bracket 11 is fixed to one end of the cross member 13, and the drive wheel bracket 11 is used to rotatably mount a drive wheel 14.

A driven wheel bracket 12 is fixed to the other end of the cross member 13, and the driven wheel bracket 12 is used to rotatably mount a driven wheel 15.

The height of the top surface of the cross member 13 is lower than the height of the top surface of the driving wheel bracket 11 and the height of the top surface of the driven wheel bracket 12, so that the height of the column 3 fixed to the cross member 13 can be reduced.

A column connecting flange 131 is fixed to the top surface of the cross beam 13. The pillar attaching flange 131 is used to detachably fix the pillar 3 by a bolt fastener or the like.

Referring to fig. 5 and 6, a first relief groove 132 is provided on a bottom surface of the cross beam 13. When the driving wheel 14 and the driven wheel 15 on the base 1 roll along the ground rail 5, the ground rail 5 extends into the first abdicating groove 132, so that the height of the bottom surface of the cross beam 13 is lower than that of the top surface of the ground rail 5, thereby reducing the height of the cross beam 13 and ensuring the strength of the cross beam 13.

Referring to fig. 7, a second elevating guide rail 133 is fixedly installed on a side surface of the cross beam 13. The second lift rail 133 includes a rail body 1331 and a rail bracket 1332.

The rail body 1331 is fixed to the rail housing 1332 to be integrated therewith. The rail bracket 1332 is detachably fixed to the cross member 13 so that the integrated second lifting rail 133 is detachably fixed to the side of the cross member 13.

Specifically, the guide rail bracket 1332 may be a plurality of fixing blocks respectively welded to both sides of the guide rail body 1331 and respectively close to the upper and lower ends of the guide rail body 1331, and a through hole for passing a bolt is formed in each fixing block, so that the second lifting guide rail 133 is detachably fixed to the side surface of the cross beam 13 by the bolt. To facilitate adjustment of the fixed height of the second lifting rail 133 on the cross beam 13, the through hole may be designed as a long strip-shaped through hole in the up-down direction.

Referring to fig. 8, a mounting hole 134 for mounting the second lift rail 133 is opened on a side surface of the cross beam 13. The number of the mounting holes 134 is equal to the number of the through holes of the fixing block constituting the rail bracket 1332, so that the bolts pass through the through holes of the fixing block and the mounting holes 134 of the side of the cross beam 13 to detachably fix the second lifting rail 133 to the side of the cross beam 13.

The mounting hole 134 has a long shape whose length direction is identical to the length direction of the cross member 13, so that the bolt can move in the mounting hole 134 in the length direction of the mounting hole 134 in a state where the bolt is loosened, thereby adjusting the front and rear positions of the second elevation guide rail 133 on the cross member 13. The front-rear position of the second elevation rail 133 on the cross member 13 is adjusted to align the rail body 1331 of the second elevation rail 133 with the body portion of the first elevation rail 31 fixed to the column 3, so that the guide wheel assembly 44 of the cargo bed 4 can be moved down from the first elevation rail 31 onto the second elevation rail 133, and the cargo bed 4 can be further lowered in height.

With continued reference to fig. 1 and 2, the drive device 2 includes a motor 21 and a transmission mechanism 22. The transmission mechanism 22 is in transmission connection with the output shaft of the motor 21 and the driving wheel 14, so that the output shaft of the motor 21 can drive the driving wheel 14 to rotate when rotating, and further drive the whole stacker to move along the ground rail 5.

The upright posts 3 are vertically fixed on the top surface of the cross beam 13. Specifically, the lower end of the upright 3 can be fixed to the upright connecting flange 131 fixed to the top surface of the cross beam 13 by a detachable fastener such as a bolt, and the upright 3 can be detached from the base 1 to be transported conveniently after the fixed connection is released.

A first lifting rail 31 is fixed to a side surface of the column 3 in the vertical direction. The first elevating guide rail 31 is a main part for guiding the elevating of the cargo bed 4, and the first elevating guide rail 31 abuts against the second elevating guide rail 133 fixed to the side surface of the cross beam 13 to form a path of the maximum length of the elevating movement of the cargo bed 4.

The upright post 3 can be an integral body which can not be disassembled again, and can also be formed by vertically butting and fixing a plurality of split bodies.

The cargo bed 4 includes a cargo bed base 41, a fork 42, and a cargo bed outer frame 43.

Referring to fig. 9, the bottom of the cargo bed base 41 is provided with a second avoiding groove 411. When the cargo bed 4 is lowered to the lowest position, the cross beam 13 extends into the second receding groove 411, so that the height of the bottom surface of the cargo bed 4 (actually, the height of the bottom surface of the cargo bed base 41) is lower than the height of the top surface of the cross beam 13, thereby further lowering the lowest lowering height of the cargo bed 4 and ensuring the strength of the cargo bed 4.

The cargo bed base 41 is provided with a guide wheel assembly 44 on one side near the upright 3, which is matched with the first lifting guide rail 31 and the second lifting guide rail 133. The first lifting guide rail 31, the second lifting guide rail 133 and the guide wheel assembly 44 cooperate to guide the lifting movement of the cargo bed 4.

Referring to fig. 10, the guide wheel assembly 44 is provided with guide wheels 441 capable of rolling along the first elevation guide rail 31 and the second elevation guide rail 133. The guide wheels 441 roll along the first and second lift rails 31 and 133 to perform a guiding function while reducing friction.

The forks 42 are provided on the cargo bed base 41 so as to be extendable and retractable. When the goods are taken from the shelf, the fork 42 extends out of the loading platform base 41 and can fork the goods on the shelf. The forks 42 retract after they have been picked up, allowing the load to be transferred to the load bed base 41. When the goods are placed, the forks 42 are extended from the platform base 41 to place the goods on the shelves, thereby completing the goods transfer.

The cargo bed outer frame 43 is fixed to the cargo bed base 41, and is used for protecting the cargo and the like on the cargo bed base 41 and preventing the cargo from falling.

The lifting device comprises a lifting driving motor, a winding drum, a steel wire rope and the like.

The winding drum is rotatably arranged at the top of the upright post 3. The lifting driving motor is in transmission connection with the winding drum, so that the winding drum can be driven to rotate. The wire rope is wound on the winding drum, so that the wire rope can be wound or released when the winding drum rotates. One end of the steel wire rope, which is far away from the winding drum, is connected to the cargo carrying platform 4, so that the cargo carrying platform 4 can be pulled to ascend when the winding drum winds the steel wire rope, and the cargo carrying platform 4 descends when the winding drum releases the steel wire rope.

The control cabinet is fixed on the base 1, and a control system is arranged in the control cabinet and used for controlling the stacker to work.

In summary, in the present application, the cross beam 13 of the base 1 is designed to have a sinking structure, that is, the height of the top surface of the cross beam 13 is lower than the height of the top surface of the driving wheel support 11 and the height of the top surface of the driven wheel support 12, so that the height of the column 3 fixed on the cross beam 13 can be reduced. The height of the upright post 3 is reduced, the lowest height of the goods carrying platform 4 which descends along the upright post 3 can be reduced, and then the height of the first layer of the goods shelf can be designed to be lower, and the storage capacity of the goods shelf is enlarged.

In the related scheme, only the guide rail for guiding the lifting of the goods carrying platform is arranged on the upright column, the goods carrying platform can only descend along the guide rail on the upright column, and the goods carrying platform cannot continuously move downwards when reaching the lower end of the guide rail. In this application scheme, be equipped with the second lifting guide rail 133 that docks mutually with first lifting guide rail 31 on the stand 3 on the side of base 1's crossbeam 13 to carry cargo bed 4 and can follow second lifting guide rail 133 and continue to descend after descending to the lower extreme of first lifting guide rail 31, carry cargo bed 4 can further descend to the space below the top surface of crossbeam 13. Therefore, through the structural improvement of the pair of stacking machines, the design height of the first layer of the goods shelf can be further reduced, and the storage capacity of the goods shelf is further enlarged.
