Description

Technical Field

[0001] The invention relates to the technical field of stacker column structure equipment, in particular to a high-position stacker column structure. Background Art

[0002] The stacker is the most important lifting and transportation equipment in the automated warehouse. It is mainly used to run along the track in the lanes of the warehouse, store the goods at the lane entrance into the cargo compartment, or take out the goods in the cargo compartment and transport them to the lane entrance to complete the storage and warehousing work. The stacker column structure is a key component of the stacker, which is mainly used to support and guide the rise and fall of the goods. The column is usually made of high-strength steel to provide stable support and movement track. The main frame structure is mainly composed of upper beams, columns, lower beams and control cabinet supports.

[0003] When the existing stacker column structure moves rapidly, the mobile platform rises at the same time. The increased weight on the top will generate inertia during rapid braking. The inertia will cause the amplitude of the column to increase. Since the stacker column is high and runs at a high speed, the free end of the column may swing and have a large amplitude due to inertia during rapid braking. This amplitude not only affects the movement stability and efficiency of the stacker, but may also reduce its service life. Summary of the invention

[0004] The object of the present invention is to provide a high-position stacker column structure to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a column structure of a high-position stacker, comprising columns, the bottoms of two columns are respectively provided with buffer members for support, and the tops of the two columns are connected to each other;

[0007] The tops of the two uprights are respectively provided with through slots, and the inner walls of the through slots are rotatably connected to two rotating wheels;

[0008] A centrifugal assembly and a counterweight assembly for counteracting inertial force are installed on the top outer wall of the column. During the centrifugal process, the centrifugal assembly pushes the hydraulic pressure to adjust the counterweight assembly.

[0009] A moving platform is slidably connected between the two uprights;

[0010] A rope winding assembly is installed on the outer wall of the bottom of the column, which includes a motor, a drum and a cable. The motor is installed on the outer wall of the column, the drum is installed on the output shaft of the motor, the cable is wound on the drum, and the other end of the cable is connected to the top of the moving platform through two rotating wheels;

[0011] A force-balanced hydraulic balance component is installed on the top of the column, and the moving platform rises to push the hydraulic balance component to operate.

[0012] The purpose of the above-mentioned setting is that during the movement of the column structure, when the mobile platform is raised and lowered by the rope winding assembly, when the goods are moved to the designated position, quick braking is required, which will generate inertia. The motor drives the drum to drive the cable to pull the mobile platform, and the cable drives the centrifugal assembly to operate. During the operation, the hydraulic pressure is pushed to adjust the counterweight assembly, and the mobile platform rises to drive the hydraulic balance assembly to operate.

[0013] Furthermore, the buffer member includes a base frame, the bottom of the base frame is rotatably connected to wheels, and the wheels move along the guide rails.

[0014] The purpose of the above arrangement is to enable the column to move.

[0015] Furthermore, four first springs are installed on the upper surface of the base frame and are distributed at four corners of the base frame. A connecting frame is installed on the top of the four first springs, and the top of the connecting frame is arranged on the outer wall of the column.

[0016] The purpose of the above arrangement is that when the column swings due to inertia, the force on the bottom of the column is dispersed through the connecting frame, and the bottom frame and the connecting frame are connected by the first spring, which plays a certain buffering role.

[0017] Furthermore, an installation cavity is provided at the top of the column, and the hydraulic balancing assembly includes a hose and a tube body, the hose and the tube body are connected to each other, a connecting plate is installed on the top of the hose, a protrusion is connected to the outer wall of the connecting plate, and the protrusion passes through the installation cavity and slides.

[0018] The purpose of the above arrangement is that during the rising process of the moving platform, the two ends of the moving platform push the protrusion and the connecting plate respectively, thereby squeezing the hose and pushing the hydraulic oil inside the hose.

[0019] Furthermore, a second spring is installed inside the tube body, and sliding blocks are installed at both ends of the second spring. The sliding blocks are slidably connected to the inner wall of the tube body, and hydraulic oil is filled between the outer wall of the sliding block and the inner wall of the bottom of the hose.

[0020] The purpose of the above arrangement is that the hydraulic oil is pushed into the interior of the tube body, located at both ends of the tube body, and simultaneously pushes and squeezes the second spring and the sliding block. The hydraulic pressure is injected from the inside of the column to the top of the column, increasing the top counterweight of the column. At the same time, the two sliding blocks move toward the middle of the tube body, thereby increasing the downward pressure of the center of gravity in the middle of the tube body, thereby reducing the swing of the column caused by inertia.

[0021] Further, the centrifugal assembly includes a shell and a rotating shaft, the shell is mounted on the top outer wall of the column, the rotating shaft passes through the column and extends to the outside of the shell, and one end of the rotating shaft is rotatably connected to a pipeline;

[0022] A sliding ring is slidably connected to the outer wall of the rotating shaft, and a first connecting rod is rotatably connected to the outer wall of the rotating shaft. A second connecting rod is connected between the first connecting rod and the sliding ring, a steel ball is connected to one end of the first connecting rod, a third spring is arranged between the sliding ring and the end of the rotating shaft, and the rotating wheel is mounted on the outer wall of the rotating shaft.

[0023] The purpose of the above-mentioned setting is that the cable and the rotating wheel rub against each other, driving the rotating wheel to rotate, thereby driving the rotating shaft to rotate, and the rotating shaft drives the first connecting rod, the second connecting rod and the steel ball to rotate. The setting of the steel ball is used to increase the centrifugal force during the rotation process. During the rapid rotation of the rotating shaft, the first connecting rod drives the first connecting rod to unfold, and the first connecting rod pulls the second connecting rod and the steel ball, thereby driving the sliding ring to slide and squeeze the third spring.

[0024] Furthermore, a sliding groove is provided on the movable column, the center of the sliding ring is connected with the movable column, the movable column is slidably connected to the inner wall of the rotating shaft, and the sliding ring is connected to the movable column through the sliding groove.

[0025] The purpose of the above arrangement is that the sliding ring drives the moving column to move, thereby pushing the hydraulic oil to move.

[0026] Furthermore, the counterweight assembly includes a counterweight block, a fourth spring and a movable block, the counterweight block is installed on the outer wall of the column, the movable block is slidably connected to the inside of the counterweight block, the fourth spring is installed between the movable block and the inner wall of the counterweight block, the pipe passes through the column and is connected to the inside of the counterweight block, and the inside of the pipe is filled with hydraulic oil.

[0027] The purpose of the above setting is that when the hydraulic oil is pushed, the hydraulic oil pushes the movable block, and the movable block moves toward one end of the counterweight block, thereby increasing the counterweight of the counterweight block. At this time, the counterweights on both sides of the two columns are increased, and a certain downward force is added to the columns respectively, thereby reducing the swing caused by inertia.

[0028] During the movement of the column structure, when the mobile platform is lifted and lowered by the rope winding assembly, when the goods are moved to the designated position, rapid braking is required, which will generate inertia. When the motor drives the drum to drive the cable to pull the mobile platform, the cable and the rotating wheel rub against each other, driving the rotating wheel to rotate, thereby driving the rotating shaft to rotate, and the rotating shaft drives the first connecting rod, the second connecting rod and the steel ball to rotate. The steel ball is set to increase the centrifugal force during the rotation process. During the rapid rotation of the rotating shaft, the first connecting rod is driven to unfold, and the first connecting rod pulls the second connecting rod and the steel ball, thereby driving the sliding ring to slide and squeeze the third spring. The sliding ring drives the mobile column to move, thereby pushing the hydraulic oil to move;

[0029] When the hydraulic oil is pushed, the hydraulic oil pushes the movable block, and the movable block moves toward one end of the counterweight block, thereby increasing the counterweight of the counterweight block. At this time, the counterweights on both sides of the two columns are increased, and a certain downward pressure is added to the columns respectively, thereby reducing the swing caused by inertia.

[0030] The present invention has the following beneficial effects:

[0031] The present invention arranges a centrifugal assembly and a counterweight block, and the cable and the rotating wheel rub against each other, driving the rotating wheel to rotate, thereby driving the rotating shaft to rotate, and the rotating shaft drives the first connecting rod, the second connecting rod and the steel ball to rotate. The arrangement of the steel ball is used to increase the centrifugal force during the rotation process. During the rapid rotation of the rotating shaft, the first connecting rod drives the first connecting rod to unfold, and the first connecting rod pulls the second connecting rod and the steel ball, thereby driving the sliding ring to slide and squeeze the third spring. The sliding ring drives the moving column to move, thereby pushing the hydraulic oil to move. When the hydraulic oil is pushed, the hydraulic oil pushes the movable block, and the movable block moves toward one end of the counterweight block, thereby increasing the counterweight of the counterweight block. At this time, the counterweights on both sides of the two columns are increased, and a certain downward force is added to the columns respectively, thereby reducing the swing and amplitude caused by inertia.

[0032] With the arrangement of the buffer member of the present invention, when the column swings due to inertia, the force on the bottom of the column is dispersed through the connecting frame, and the bottom frame and the connecting frame are connected by the first spring, which plays a certain buffering role.

DETAILED DESCRIPTION

[0047] A centrifugal assembly 5 and a counterweight assembly are installed on the top outer wall of the column 1 to offset the inertial force. During the centrifugal process, the centrifugal assembly 5 pushes the hydraulic pressure to adjust the counterweight assembly.

[0048] A moving platform 3 is slidably connected between the two uprights 1;

[0049] A rope winding assembly is installed on the bottom outer wall of the column 1, which includes a motor, a drum and a cable. The motor is installed on the outer wall of the column 1, the drum is installed on the output shaft of the motor, the cable is wound on the drum, and the other end of the cable is connected to the top of the moving platform 3 through two rotating wheels 7;

[0050] A force-balanced hydraulic balancing assembly 4 is installed on the top of the column 1, and the moving platform 3 rises to push the hydraulic balancing assembly 4 to operate.

[0051] In the process of fast movement of the existing stacker column structure, the mobile platform rises at the same time. The increased top weight will generate inertia during the rapid braking process. The inertia will cause the amplitude of the column to increase. Since the stacker column is high and the running speed is fast, the free end of the column may swing and have a large amplitude due to inertia during rapid braking. This amplitude not only affects the movement stability and efficiency of the stacker, but also may reduce its service life.

The motor drives the drum to drive the cable to pull the mobile platform 3, and the cable drives the centrifugal assembly 5 to operate. During the operation, the hydraulic pressure is pushed to adjust the counterweight assembly, and the mobile platform 3 rises to drive the hydraulic balance assembly 4 to operate, thereby reducing the swing of the column 1 caused by inertia.

The hydraulic pressure is injected from the interior of the column 1 to the top of the column 1, increasing the top counterweight of the column 1. At the same time, the two sliding blocks 405 move toward the middle of the tube body 403, thereby increasing the downward pressure of the center of gravity in the middle of the tube body 403, thereby reducing the swing of the column 1 due to inertia.
