Description

Technical Field

[0001] The present invention relates to a stacker, in particular to a double-column stacker used in a low space. Background Art

[0002] With the acceleration of urbanization, urban land resources are becoming increasingly scarce. Many old factories often occupy a large space. Transforming them into high-rise warehouses can make full use of idle space, improve land utilization, and provide more space resources for urban development. Due to the limitations and non-scalability of the available height space in old factories, the use of stackers in them is restricted. As a key equipment in high-rise warehouses, the complete structure of stackers mainly consists of a ceiling rail system, a ground rail system, an upper beam, a column, a loading platform, a lower beam, a sliding line system, etc. Conventional stackers need to occupy a large height space of the factory building, which ultimately leads to the space utilization rate of the high-rise warehouse after the old factory building is transformed not meeting the expected effect. How to develop a stacker for use in low spaces has become a problem that needs to be solved on site. Summary of the Invention

[0003] The invention provides a double-column stacker used in a low space, solving the technical problem of how to develop a stacker that can be used in a low space.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A double-column stacker for use in a low space comprises a stacker lower crossbeam, a left column and a right column are respectively provided on the stacker lower crossbeam, a cargo platform is provided between the left column and the right column, a left hanger and a right hanger are respectively provided on the cargo platform, a left guide wheel pair is provided on the outer side of the left hanger, the left guide wheel pair is movably connected to the left column, a right guide wheel pair is provided on the outer side of the right hanger, and the right guide wheel pair is movably connected to the right column; a lifting platform drive motor and a reducer are provided at the lower end of the right side facade of the right column, a front side wire rope drum is provided on the front end shaft of the double-end output shaft of the lifting platform drive motor and reducer, and a rear side wire rope drum is provided on the rear end shaft of the double-end output shaft of the lifting platform drive motor and reducer; a first rotating shaft is provided at the top of the right column. The rear wire rope released from the rear wire rope drum passes through the third steering fixed pulley, the fourth steering fixed pulley, the seventh steering fixed pulley and the eighth steering fixed pulley in sequence and is connected to the rear wire rope end connecting column.

[0006] A laser rangefinder is arranged on the top surface of the stacker lower beam; a traveling wheel is arranged on the lower bottom surface of the stacker lower beam, and the stacker lower beam is arranged on the stacker walking track through the traveling wheel.

[0007] When the lift platform drive motor and reducer rotate forward, the front wire rope is wound around the front wire rope drum, and at the same time, the rear wire rope is wound around the rear wire rope drum, and the cargo platform rises under the joint action of the front wire rope and the rear wire rope; when the lift platform drive motor and reducer rotate reversely, the front wire rope is released from the front wire rope drum, and at the same time, the rear wire rope is released from the rear wire rope drum, and the cargo platform descends under the joint suspension of the front wire rope and the rear wire rope; when the cargo platform interacts with the laser rangefinder to give a position stop signal, the lift platform drive motor and reducer stop.

[0008] The present invention reduces the space of the stacker by eliminating the overhead rail and the upper crossbeam, and improves stability by changing the double columns to four columns and the single track to double tracks. While improving the utilization rate of the plant space, the stability of the equipment is guaranteed at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Pulley 14, second steering fixed pulley 15, third steering fixed pulley 21 and fourth steering fixed pulley, a fifth steering fixed pulley 16 and a sixth steering fixed pulley 17 are respectively provided on the front side of the cargo platform 9, and a seventh steering fixed pulley 22 and an eighth steering fixed pulley are respectively provided on the rear side of the cargo platform 9, and a front wire rope end connecting column 18 and a rear wire rope end connecting column are respectively provided on the right side of the top end of the left column 4; the front wire rope 8 released from the front wire rope drum 7 passes through the first steering fixed pulley 14, the second steering fixed pulley 15, the fifth steering fixed pulley 16 and the sixth steering fixed pulley 17 in sequence and is connected to the front wire rope end connecting column 18; the rear wire rope 20 released from the rear wire rope drum 19 passes through the third steering fixed pulley 21, the fourth steering fixed pulley, the seventh steering fixed pulley 22 and the eighth steering fixed pulley in sequence and is connected to the rear wire rope end connecting column.

[0013] A laser rangefinder 23 is provided on the top surface of the stacker lower beam 2; a running wheel 3 is provided on the lower bottom surface of the stacker lower beam 2, and the stacker lower beam 2 is set on the stacker running track 1 through the running wheel 3.

[0014] A method for operating a double-column stacker in a low space is implemented by using a double-column stacker in a low space, comprising the following steps:

[0015] Step 1: When the lifting platform drive motor and reducer 6 rotate in the forward direction, the front wire rope 8 is wound around the front wire rope drum 7. At the same time, the rear wire rope 20 is wound around the rear wire rope drum 19. The cargo platform 9 rises under the joint action of the front wire rope 8 and the rear wire rope 20.

[0016] Step 2: When the lifting platform drive motor and reducer 6 rotate in the opposite direction, the front wire rope 8 is released from the front wire rope drum 7. At the same time, the rear wire rope 20 is released from the rear wire rope drum 19. The cargo platform 9 descends under the joint suspension of the front wire rope 8 and the rear wire rope 20. When the cargo platform 9 interacts with the laser rangefinder 23 to give a position stop signal, the lifting platform drive motor and reducer 6 stop.

[0017] The overhead rail system, the stacker's upper beam and the upper guide wheel are eliminated, and the fixed pulley of the wire rope on the upper beam is installed on the right column, the movable pulley is installed on the bottom of the cargo platform, and drums are installed on both sides of the drive motor. One end of the two steel ropes is wound and fixed to the drums on both sides of the drive motor, respectively, passes through the two fixed pulleys, and is wrapped around the two movable pulleys under the cargo platform, and finally the other end of the steel rope is fixed to the plate extending from the left column. The drum is driven by the drive motor to rotate to achieve the lifting of the cargo platform, and the dual closed-loop control of the encoder installed on the drive motor and the laser rangefinder under the stacker's cargo platform is used to achieve precise vertical positioning of the cargo platform; the running track adopts the form of double tracks, and the columns are changed to four columns. While reducing the track specifications and column specifications, the stability of the structure operation can still be maintained; finally, the stacker's occupation of vertical space can be compressed by removing the upper guide rail and the stacker's upper beam, and the stability of the equipment can be maintained by using double running tracks and four columns.
