Description

Technical Field

[0001] The invention relates to the technical field of single-column stackers, in particular to a single-column automatic lifting stacker. Background Art

[0002] Stacker is a very important logistics handling equipment in high-rise warehouses. Its main purpose is to run along a fixed track in the aisles of high-rise shelf warehouses, take out the goods on the designated aisle entrance platform and store them in the designated shelf cargo compartment; or vice versa, take out the goods in the designated shelf cargo compartment and transport them to the designated aisle entrance platform to complete the corresponding warehousing operations.

[0003] With the continuous advancement of technology and the continuous changes in market demand, higher requirements are also put forward for the performance of single-column stackers. For example, higher access speed, greater load capacity, more stable operating performance and lower maintenance cost are required; and the anti-fall device of the existing stacker is not only heavy, complex to manufacture, and high in manufacturing cost, but also difficult to maintain and prone to malfunction. Therefore, it is necessary to design a single-column automatic lifting stacker.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention

[0005] Based on this, it is necessary to provide a single-column automatic lifting stacker to address the above technical problems.

[0006] In order to achieve the above object, the present invention provides a single-column automatic lifting stacker, comprising: The rack is slidably mounted on the floor rails and ceiling rails; The lifting mechanism comprises a first rotary drive device, a steel rope traction wheel, an inlet wheel, an outlet wheel, a cargo platform, a lifting wheel, a buffer frame and two first linear actuators, wherein the mounting ends of the first rotary drive device and the steel rope traction wheel are mounted on a frame, the output end of the first rotary drive device is transmission-connected with the steel rope traction wheel, two inlet wheels and two outlet wheels are rotatably mounted on the top of the frame, the cargo platform is slidably clamped on the frame, the lifting wheel is rotatably mounted on the cargo platform, the buffer frame is mounted on the frame, and the two first linear actuators are distributed and mounted at both ends of the ground rail; The falling protection mechanism comprises a protection steel rope, a deformation mechanism, a protection rail, a U-shaped frame, a brake frame, an abutment frame, a connecting rod, a friction wheel, an abutment push rod, an abutment rod, a block, a clamping rod, a top rod and a limiting mechanism. The bottom end of the protection steel rope is fixedly installed on the frame, the deformation mechanism and the protection rail are both installed on the frame, the top end of the protection steel rope passes through the deformation mechanism, the U-shaped frame is slidably clamped on the cargo platform, the brake frame and the abutment frame are both installed on the U-shaped frame, the brake frame and the protection rail are cooperated, the connecting rod is rotatably installed on the abutment frame, one end of the connecting rod is rotatably installed with a friction wheel, the friction wheel abuts the protection steel rope, the end of the connecting rod away from the friction wheel is rotatably installed with an abutment push rod, the abutment rod is installed on the cargo platform, the abutment push rod and the abutment rod are cooperated, a clamping block is slidably clamped on the abutment frame, a clamping rod is slidably clamped in the clamping block, a top rod is rotatably installed on the bottom of the clamping rod through a universal ball, the end of the top rod away from the clamping rod is installed on the connecting rod, and a limiting mechanism is installed on the abutment rod.

[0007] The cargo can be moved to different places by the sliding of the frame on the ground rail and the ceiling rail. The steel rope wound on the steel rope traction wheel is led out from it, passes through the two inlet wheels and extends downward to the lifting wheel on the cargo platform, passes through it and then extends upward, passes through the two outlet wheels and is fixed on the frame, so that the inlet wheel and the outlet wheel are equivalent to the fixed pulley and the movable pulley, which can better lift the lifting wheel, thereby lifting the cargo platform and the cargo on it, and the lifting wheel itself can rotate, which is more stable than the previous fixed lifting, and the connection is not easy to break. There are two inlet wheels and outlet wheels, so that part of the force of the steel rope on itself can be converted into the relative force between the two inlet wheels or the outlet wheels, so that the bearing connection of the inlet wheel and the outlet wheel is not easily damaged, and heavier cargo can be carried. When the frame moves to the two ends of the ground rail, the first linear actuator can decelerate and buffer it, so that the frame can carry cargo at a faster speed. When the cargo platform is lifted or lowered normally, the U-shaped frame can drive the friction wheel on the connecting rod to normally abut and rub against the protective steel rope. When the steel rope on the steel rope traction wheel is disconnected, the cargo platform falls rapidly, and the friction between the friction wheel and the protective steel rope increases, so that the friction wheel can drive the inclined connecting rod to rotate on the U-shaped frame, changing from the original inclined state to an approximately horizontal state, so that the abutment push rod on the other side of the connecting rod can abut and collide with the abutment rod on the cargo platform, so that the collision force can push the U-shaped frame from the cargo platform through the abutment frame, and the brake frame on the U-shaped frame can abut and rub against the protective steel rail, thereby slowing down the descent of the cargo platform. When the connecting rod gradually changes from an inclined state to a horizontal state, the card rod in the card block can be driven by the top rod on the connecting rod to slide outward. When the connecting rod is completely changed to a horizontal state, the top rod also pulls the card rod out completely, so that the top end of the card rod abuts against the card block, and the card rod and the top rod are connected by the rotation of the universal ball. When the U-shaped frame is moved out of the loading platform, the brake frame abuts against the protective rail, so that the connecting rod will not become tilted from the other direction, thereby achieving the purpose of locking, and a baffle can be installed under the connecting rod to make it difficult to become tilted from the other side when it becomes approximately horizontal; when the connecting rod becomes horizontal, the friction wheel on it will also squeeze the protective steel rope, and the deformation mechanism on the top of the frame can be contracted to a certain extent, so that the protective steel rope can be smoothly stretched; the limit rod enables the abutment push rod rotating on the connecting rod to maintain a certain vertical state, thereby facilitating its abutment and collision with the abutment rod.

[0008] Optionally, the protective rail is U-shaped, and the height of the protective rail away from one side of the cargo platform is only half of that of the other side.

[0009] By adopting the above technical solution, when the brake frame comes into contact and rubs against the protective rail, it will first rub against one side of it. When the speed of the cargo platform is still relatively fast, it can come into contact with the protective rail on the other side, further improving the braking effect of the cargo platform. The bottom end of the friction point on the brake frame that acts on the shorter side of the protective rail should be inclined at a certain angle to facilitate friction with the protective rail.

[0010] Optionally, the deformation mechanism includes a mounting seat, a movable seat, a rotating wheel, a deformation limit rod and a spring. The mounting seat is installed on the top of the frame, and the movable seat is slidably connected to the mounting seat through the deformation limit rod. A rotating wheel is rotatably installed on the movable seat, and a protective steel rope passes through the rotating wheel. A spring is installed on the mounting seat, and the output end of the spring is connected to the movable seat.

[0011] By adopting the above technical solution, when the protective steel rope is stretched by the friction wheel, the protective steel rope can give pressure to the rotating wheel, so that it drives the moving seat to press down. Through the guiding action of the deformed limit rod and the compression of the spring, the moving seat can descend relative to the mounting seat, and can be supported by the spring to move up again after the pressure of the protective steel rope disappears.

[0012] Optionally, the limiting mechanism includes two mounting rings 1, two mounting rings 2 and a spring 2, the two mounting rings 1 are respectively mounted on the two ends of the abutting push rod, the two mounting rings 2 are both mounted on the abutting rod, the two mounting rings 2 are located on the upper and lower sides of the abutting push rod, and the corresponding mounting rings 1 and the two mounting rings 2 are connected by a spring 2.

[0013] By adopting the above technical solution, the mounting ring 2 on the abutment rod is connected to the mounting ring 1 on the abutment push rod through the spring 2, so that the abutment push rod can maintain a certain vertical state and the connecting rod can maintain an inclined state. When the connecting rod becomes approximately horizontal, the tension of the spring 2 is less than the friction between the friction wheel and the protective steel rope when the cargo platform descends, and is not enough to make the connecting rod tilt again.

[0014] Optionally, the U-shaped frame is provided with a through slot, and a plurality of rollers 1 and 2 are rotatably mounted on the cargo platform, the rollers 1 and 2 are both in contact with the frame, and the rollers 1 and the contact rods pass through the through slot.

[0015] By adopting the above technical solution, when the U-shaped frame is driven to slide out, the through groove ensures that the position of roller one and the abutment rod will not change, and they can still abut against the frame. Roller one and roller two reduce the sliding friction between the cargo platform and the frame. The abutment rod should also be installed with rollers and abut against the frame, thereby reducing the friction between the abutment rod and the frame.

[0016] Optionally, the lifting mechanism also includes an electrical control cabinet, a terminal limit switch and two layer selection recognition plates. The electrical control cabinet and the steel rope traction wheel are installed on the same side of the frame, the terminal limit switch is installed on the cargo platform, and the two layer selection recognition plates are respectively installed at the upper and lower ends of the frame. The terminal limit switch and the two layer selection recognition plates are arranged in coordination.

[0017] By adopting the above technical solution, the electrical control cabinet, the first rotary drive device and the steel rope traction wheel are installed on the same side, making the overall structure of the stacker more compact, and the upper and lower layer selection addressing plates and the terminal limit switches on the cargo platform cooperate with each other, so that the lifting position of the cargo platform can be determined.

[0018] Optionally, the lifting mechanism also includes a motor mounting plate, a motor inclined plate and an L-shaped connecting plate, the motor mounting plate is mounted on the frame, the motor inclined plate is mounted on the motor mounting plate, the motor mounting plate and the bottom of the motor inclined plate are connected by a cross bar, the L-shaped connecting plate is mounted on the motor inclined plate, the first rotation drive device is placed on the bottom plate of the L-shaped connecting plate and connected to the side plate of the L-shaped connecting plate, and the steel rope traction wheel is connected to the L-shaped connecting plate.

[0019] By adopting the above technical solution, the motor mounting plate, the motor inclined plate and the cross bars at the bottom of the two form a triangle, so that the installation of the first rotary drive device and the steel rope traction wheel on the L-shaped plate is more stable.

[0020] Optionally, a driving wheel and a driven wheel are rotatably installed at the bottom of the frame, a second rotation driving device is installed at the bottom of the frame, the output end of the second rotation driving device is transmission-connected to the driving wheel, the second rotation driving device is located under the electrical control cabinet, and auxiliary wheels are rotatably installed at the front and rear ends in the direction of travel of the frame, and the driving wheel, driven wheel and auxiliary wheels are all in contact with the ground rail.

[0021] By adopting the above technical solution, by installing the second rotary drive device under the electrical control cabinet, the structure of the entire stacker is made more compact, and the frame is driven forward by the driving wheel and the driven wheel, and the auxiliary role of the auxiliary wheel makes the frame more stable when moving.

[0022] Optionally, a cleaning brush is installed on one side of the auxiliary wheel away from the frame.

[0023] By adopting the above technical solution, the cleaning brush cleans the ground rail, so that the driving wheel, the driven wheel and the auxiliary wheel can move more stably.

[0024] Optionally, a second auxiliary wheel is installed on the top of the frame, and the second auxiliary wheel is in contact with the ceiling rail.

[0025] By adopting the above technical solution, the auxiliary wheels and the ceiling rails are rotated in contact with each other, so that the frame can be more stable when moving forward.

[0026] This technical solution has at least the following beneficial effects: 1. After the steel rope on the steel rope traction wheel is loaded by the rotation of the two inlet wheels and the outlet wheels, the rotatable lifting wheel on the cargo platform is lifted, so that part of the pressure on the two inlet wheels or the outlet wheels can be converted into the relative pressure between the two inlet wheels or the outlet wheels. Compared with the single-wheel setting, the two wheels can better carry the goods, thereby increasing the load capacity of the goods. The first linear actuator installed on both sides of the ground rail buffers the running frame, so that it can better reduce the speed, so that the transportation of goods can be faster, thereby improving the transportation efficiency; 2. By providing a connecting rod and a friction wheel and an abutting push rod thereon, when the cargo platform falls, the friction between the friction wheel and the protective steel rope can make the connecting rod become horizontal, so that the abutting push rod on the connecting rod pushes the abutting rod, so that the entire U-shaped frame can slide out from the cargo platform, and the brake frame on the U-shaped frame can cooperate with the protective steel rail for friction to brake and protect the cargo platform, thereby further reducing the cost of the anti-falling device through a simple structure; 3. After the connecting rod becomes horizontal, the clamping rod on the clamping block can be driven by the push rod to slide out, so that the clamping rod and the push rod change from the original straight state to a bent state, so that the connecting rod can no longer be rotated from the horizontal state to the inclined state again, thereby achieving a locking effect, thereby further reducing the cost of the anti-fall device through a simple structure.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0029] See also Figures 1 to 10 , the embodiment of the present application provides a single-column automatic lifting stacker, comprising: The frame 1 is slidably mounted on the ground rail 11 and the ceiling rail 12; The lifting mechanism 2 includes a first rotary drive device 21, a steel rope traction wheel 22, an inlet wheel 23, an outlet wheel 24, a cargo platform 25, a lifting wheel 26, a buffer frame 27 and two first linear actuators 28. The first rotary drive device 21 is a servo motor, and the first rotary drive device 21 is connected to the steel rope traction wheel 22 through a reducer. The first linear actuator 28 can be a hydraulic cylinder. The mounting ends of the first rotary drive device 21 and the steel rope traction wheel 22 are installed on the frame 1, and the output end of the first rotary drive device 21 is connected to the steel rope traction wheel 22. Two inlet wheels 23 and two outlet wheels 24 are rotatably installed on the top of the frame 1. The cargo platform 25 is slidably connected to the frame 1, and the lifting wheel 26 is rotatably installed on the cargo platform 25. The buffer frame 27 is installed on the frame 1, and the two first linear actuators 28 are distributed and installed at both ends of the ground rail 11; The falling protection mechanism 3 includes a protection steel rope 301, a deformation mechanism 302, a protection rail 303, a U-shaped frame 304, a brake frame 305, an abutment frame 306, a connecting rod 307, a friction wheel 308, an abutment push rod 309, an abutment rod 310, a clamping block 311, a clamping rod 312, a top rod 313 and a limiting mechanism 314. The brake frame 305 is provided with a plurality of threaded holes for installing friction blocks, and the friction blocks abut and rub against the protection rail 03. The bottom end of the protection steel rope 301 is fixedly installed on the frame 1, the deformation mechanism 302 and the protection rail 303 are both installed on the frame 1, the top end of the protection steel rope 301 passes through the deformation mechanism 302, the U-shaped frame 304 is slidably clamped on the cargo platform 25, and the brake frame 305 and the abutment frame 306 are installed On the U-shaped frame 304, the brake frame 305 is matched with the protection rail 303, the connecting rod 307 is rotatably installed on the abutment frame 306, one end of the connecting rod 307 is rotatably installed with a friction wheel 308, the friction wheel 308 abuts against the protection steel rope 301, the end of the connecting rod 307 away from the friction wheel 308 is rotatably installed with an abutment push rod 309, the abutment rod 310 is installed on the cargo platform 25, the abutment push rod 309 and the abutment rod 310 are matched, a clamping block 311 is installed on the abutment frame 306, a clamping rod 312 is slidably clamped in the clamping block 311, a push rod 313 is rotatably installed at the bottom of the clamping rod 312 through a universal ball, the end of the push rod 313 away from the clamping rod 312 is installed on the connecting rod 307, and a limiting mechanism 314 is installed on the abutment rod 310.

[0030] The goods can be moved to different places by sliding the frame 1 on the ground rail 11 and the ceiling rail 12. The steel rope wound on the steel rope traction wheel 22 is led out from it, passes through the two inlet wheels 23 and extends downward to the lifting wheel 26 on the cargo platform 25, passes through it and then extends upward, passes through the two outlet wheels 24 and is fixed on the frame 1, so that the inlet wheel 23 and the outlet wheel 24 are equivalent to the fixed pulley and the movable pulley, which can better lift the lifting wheel 26, thereby lifting the cargo platform 25 and the goods thereon, and the lifting wheel 26 can rotate by itself, which is more stable and less likely to break than the previous fixed lifting. There are two in-line wheels 23 and out-line wheels 24, so that a part of the force of the steel rope on itself can be converted into the relative force between the two in-line wheels 23 or the out-line wheels 24, so that the bearing connection of the in-line wheels 23 and the out-line wheels 24 is not easily damaged, and heavier goods can be carried. When the frame 1 moves to the two ends of the ground rail 11, the first linear actuator 28 can slow it down and buffer it, so that the frame 1 can carry goods at a faster speed.When the cargo platform 25 is normally raised or lowered, the U-shaped frame 304 can drive the friction wheel 308 on the connecting rod 307 to normally abut against the protective steel rope 301. When the steel rope on the steel rope traction wheel 22 is disconnected, the cargo platform 25 falls rapidly, and the friction between the friction wheel 308 and the protective steel rope 301 increases, so that the friction wheel 308 can drive the inclined connecting rod 307 to rotate on the U-shaped frame 304, changing from the original inclined state to an approximately horizontal state, so that the abutting push rod 309 on the other side of the connecting rod 307 can abut and collide with the abutting rod 310 on the cargo platform 25, thereby The force of the collision can push the U-shaped frame 304 from the cargo platform 25 through the abutment frame 306, and the brake frame 305 on the U-shaped frame 25 can abut and rub against the protective rail 303, thereby slowing down the descent of the cargo platform. When the connecting rod 307 gradually changes from an inclined state to a horizontal state, the clamping rod 312 in the clamping block 311 can be driven by the push rod 313 on the connecting rod 307 to slide outward. When the connecting rod 307 completely changes to a horizontal state, the push rod 313 also pulls the clamping rod 312 completely out, so that the top end of the clamping rod 312 abuts against the clamping block 311, and the clamping rod 312 and the push rod 313 are The universal ball is used for rotation connection between the push rod 313 and the push rod 314, so that the angle change during the outward movement of the push rod 313 can be adjusted by rotation. When the push rod 313 pulls the clamping rod 312 out completely, the two are no longer in a straight line, so that the push rod 313 is not easy to drive the clamping rod 312 to reset, that is, the connecting rod 307 is not easy to change from a horizontal state to an inclined state; when the connecting rod 307 is in a horizontal state, the push rod 309 on it abuts against the abutting rod 310 on the cargo platform 25, and the connecting rod 307 drives the U-shaped frame 304 to move out and abut against the rear brake frame 305 and the protective rail 303, so that the connecting rod 307 07 will not tilt from the other direction again, thus achieving the purpose of locking, and a baffle can be installed under the connecting rod 307 to prevent it from tilting from the other side when it becomes approximately horizontal; when the connecting rod 307 becomes horizontal, the friction wheel 308 thereon will also squeeze the protective steel rope 301, and at this time the deformation mechanism 302 on the top of the frame 1 can shrink to a certain extent, so that the protective steel rope 301 can be smoothly stretched; the limiting rod 314 allows the abutting push rod 309 rotating on the connecting rod 307 to maintain a certain vertical state, thereby facilitating its abutment and collision with the abutting rod 310.

[0031] In one embodiment, see Figure 8 The protective rail 303 is U-shaped, and the height of the protective rail 303 away from the side of the cargo platform 25 is only half of the height of the other side.

[0032] By adopting the above technical solution, when the brake frame 305 abuts and rubs against the protective rail 303, it first rubs against one side of it. When the speed of the cargo platform 25 is still relatively fast, it can abut against the protective rail 303 on the other side, thereby further improving the braking effect of the cargo platform 25. The bottom end of the friction point on the brake frame 305 that acts on the shorter side of the protective rail 303 should be inclined at a certain angle to facilitate friction with the protective rail 303.

[0033] In one embodiment, see Fig.10 The deformation mechanism 302 includes a mounting seat 3021, a moving seat 3022, a rotating wheel 3023, a deformation limiting rod 3024 and a spring 3025. The mounting seat 3021 is installed on the top of the frame 1. The moving seat 3022 is slidably connected to the mounting seat 3021 through the deformation limiting rod 3024. The rotating wheel 3023 is rotatably installed on the moving seat 3022. The protective steel rope 301 passes through the rotating wheel 3023. The mounting seat 3021 is installed with a spring 3025, and the output end of the spring 3025 is connected to the moving seat 3022.

[0034] By adopting the above technical solution, when the protective steel rope 301 is abutted and stretched by the friction wheel 308, the protective steel rope 301 can give pressure to the rotating wheel 3023, so that it drives the movable seat 3022 to be pressed down. Through the guiding effect of the deformed limit rod 3024 and the compression of the spring 3025, the movable seat 3022 can be lowered relative to the mounting seat 3021, and can be supported by the spring 3025 to move up again after the pressure of the protective steel rope 301 disappears.

[0035] In one embodiment, see Figure 8 The limiting mechanism 314 includes two mounting rings 1 3141, two mounting rings 2 3142 and a spring 2 3143. The two mounting rings 1 3141 are respectively mounted on both ends of the abutting push rod 309, and the two mounting rings 2 3142 are both mounted on the abutting rod 310. The two mounting rings 2 3142 are located at the upper and lower sides of the abutting push rod 309, and the corresponding mounting rings 1 3141 and the two mounting rings 2 3142 are connected by the spring 2 3143.

[0036] By adopting the above technical solution, the mounting ring 2 3142 on the abutment rod 310 is connected to the mounting ring 1 3141 on the abutment push rod 309 through the spring 2 3143, so that the abutment push rod 309 can maintain a certain vertical state and the connecting rod 307 can maintain an inclined state. When the connecting rod 307 becomes approximately horizontal, the tension of the spring 2 3143 is less than the friction between the friction wheel 308 and the protective steel rope 301 when the cargo platform 25 descends, and is not enough to make the connecting rod 307 tilted again.

[0037] In one embodiment, see Figure 8A through slot 3041 is provided on the U-shaped frame 304, and a plurality of rollers 1 3042 and rollers 2 3043 are rotatably mounted on the cargo platform 25, and the rollers 1 3042 and rollers 2 3043 are both in contact with the frame 1, and the rollers 1 3042 and the contact rods 310 pass through the through slot 3041.

[0038] By adopting the above technical solution, when the U-shaped frame 304 is driven to slide out, the through groove 3041 ensures that the roller 1 3042 and the abutment rod 310 will not change position and can still abut against the frame 1. The roller 1 3042 and the roller 2 3043 reduce the sliding friction between the cargo platform 25 and the frame 1. The abutment rod 310 should also be installed with rollers and abut against the frame 1, thereby reducing the friction between the abutment rod 310 and the frame 1.

[0039] In one embodiment, see Figure 2 , Figures 13 to 15 The lifting mechanism 2 also includes an electrical control cabinet 201, a terminal limit switch 202 and two layer selection recognition plates 203. The electrical control cabinet 201 and the steel rope traction wheel 22 are installed on the same side of the frame 1, the terminal limit switch 202 is installed on the cargo platform 25, and the two layer selection recognition plates 203 are respectively installed at the upper and lower ends of the frame 1. The terminal limit switch 202 and the two layer selection recognition plates 203 are arranged in coordination.

[0040] By adopting the above technical solution, the electrical control cabinet 201, the first rotary drive device 21 and the steel rope traction wheel 22 are installed on the same side, so that the overall structure of the stacker is more compact, and the upper and lower layer selection addressing plates 203 and the terminal limit switch 202 on the cargo platform 25 cooperate with each other, so that the lifting position of the cargo platform 25 can be determined.

[0041] In one embodiment, see Fig.15 The lifting mechanism 2 also includes a motor mounting plate 204, a motor inclined plate 205 and an L-shaped connecting plate 206.
