A type of anti-fall stacker crane

Abstract

This invention discloses a fall-prevention aisle-type stacker crane, belonging to the field of stacker crane technology. It includes a moving device for driving the stacker crane, and a drive unit and an end-effector for lifting or lowering goods. The moving device enables the stacker crane to move and achieves steering through a steering mechanism. Limit blocks restrict the steering limits of the crane body, preventing directional confusion due to excessive steering wheel rotation. A center-of-gravity mechanism extends the sliding frame when the end-effector is raised, ensuring the stacker crane remains balanced when the lifting platform lifts goods, preventing tipping and potential falls of personnel or goods. A rotating mechanism adjusts the angle between the rotating forks and the moving forks, with both rotating forks rotating in the same direction to accommodate more pick-up and drop angles. An inward-retracting mechanism adjusts the distance between the two moving forks to accommodate goods of different widths.

Description

Technical Field

[0001] This invention relates to the field of stacker crane technology, and in particular to a fall-proof aisle stacker crane. Background Technology

[0002] Stacker cranes are the most important lifting and transport equipment in automated warehouses and are representative of the characteristics of automated warehouses;

[0003] Aisle stacker cranes are a type of machine evolved from forklifts and bridge stacker cranes. Due to the bulky size of traditional bridge stacker cranes, they are only suitable for long raw materials with low infrequent warehouse entry and exit, and cannot handle heavy goods. They also cannot flexibly handle raw materials of various sizes. Existing aisle stacker cranes are usually structurally redundant, complex to operate, and inconvenient to use. Furthermore, when moving or lifting goods, existing aisle stacker cranes may tip over due to an unstable center of gravity, causing accidents such as goods falling and operators falling. The center of gravity of the stacker crane needs to be adjusted when lifting goods. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention adopts the following technical solution: a fall-proof aisle stacker crane, comprising a mobile device, the mobile device comprising a vehicle body, the mobile device being used to drive the stacker crane to move, the mobile device being provided with a drive device and an end device, the drive device comprising a lifting motor fixedly mounted on the vehicle body, the end device comprising a lifting plate, a lifting slider fixedly mounted on the lifting plate, the lifting slider being slidably mounted on the vehicle body, the end device being used to lift or lower goods.

[0005] Furthermore, the mobile device includes a traveling gear fixedly mounted on the motor shaft of the traveling motor, a traveling shaft rotatably mounted on the vehicle body, two traveling wheels fixedly mounted on the traveling shaft, a traveling transmission belt wound around the traveling gear and the traveling shaft, and a seat provided on the vehicle body.

[0006] Furthermore, the vehicle body is equipped with a steering mechanism, which includes a steering wheel rotatably mounted on the vehicle body, an active rotating frame fixedly mounted on the steering wheel, an upper cross shaft rotatably mounted on the active rotating frame, an intermediate rotating frame rotatably mounted on the upper cross shaft, a lower cross shaft rotatably mounted on the intermediate rotating frame, a vertical rotating shaft rotatably mounted on the lower cross shaft, the vertical rotating shaft being rotatably mounted to the vehicle body, a steering gear fixedly mounted on the vertical rotating shaft, two steering wheel frames rotatably mounted on the vehicle body, steering wheels rotatably mounted on the steering wheel frames, an outer steering gear fixedly mounted on the steering wheel frames, a steering transmission belt wound around the two outer steering gears and the steering gear, a rotation limit block fixedly mounted on the steering wheel frame, and a limit block fixedly mounted at the bottom of the vehicle body.

[0007] The operator sits in the vehicle's seat. The drive motor rotates, driving the drive gears, which in turn drive the drive shaft and drive wheels via the drive belt, thus moving the vehicle. Turning the steering wheel drives the drive frame, which in turn drives the vertical shaft via the upper cross shaft, middle frame, and lower cross shaft, which in turn drives the steering gear. The steering belt drives the outer steering gear and steering wheel frame, which in turn drives the steering wheels, thus turning the vehicle. When the steering wheel frame rotates, it also drives the steering limit block to rotate. When the steering limit block contacts the limit block, it is blocked by the limit block, at which point the steering wheel frame cannot continue to rotate, thus limiting the steering limit of the vehicle and preventing the movement direction from becoming chaotic due to excessive steering wheel rotation.

[0008] Furthermore, the drive device includes a motor gear fixedly mounted on the motor shaft of the lifting motor, an internal gear rotatably mounted on the vehicle body, an external mating gear fixedly mounted on the internal gear, the external mating gear meshing with the motor gear, an intermediate gear and an external belt gear rotatably mounted on the vehicle body, a mating gear fixedly mounted on the external belt gear, and a long transmission belt wrapped around the external belt gear, intermediate gear, and internal gear.

[0009] Furthermore, the vehicle body is provided with a center of gravity mechanism, which includes a sliding frame slidably mounted on the bottom of the vehicle body, a sliding rack fixedly mounted on the sliding frame, two sliding rollers rotatably mounted on the sliding frame, an inner lower gear rotatably mounted on the vehicle body, a center of gravity adjusting gear fixedly mounted on the inner lower gear, a vertical transmission belt wrapped around the inner lower gear and the middle gear, and the center of gravity adjusting gear meshing with the sliding rack.

[0010] The lifting motor rotates, driving the motor gears to rotate, which in turn drive the outer and inner gears. This, in turn, drives the intermediate and outer gears via a long transmission belt, which in turn drives the docking gears to rotate. This causes the lifting rack and lifting plate to rise, lifting the goods. The intermediate gear, via a vertical transmission belt, drives the inner lower gear and the center of gravity adjustment gear to rotate, which in turn causes the sliding rack and sliding frame to slide along the vehicle body. The sliding rollers roll on the ground, causing the sliding frame to move towards the lifting plate. This ensures that the stacker crane remains balanced when the lifting plate lifts the goods, preventing tipping and the fall of personnel or goods.

[0011] Furthermore, the end device includes a guide groove fixedly installed on the lifting plate, a lifting rack fixedly installed on the lifting plate, the lifting rack meshing with a mating gear, an electric cylinder fixedly installed on the lifting plate, a lifting motor frame fixedly installed on the top of the electric cylinder, the lifting motor frame slidingly installed with the lifting plate, a rotating motor fixedly installed on the lifting motor frame, a lifting gear fixedly installed on the motor shaft of the rotating motor, and a mating gear provided on the lifting gear.

[0012] Furthermore, the guide slide groove is provided with an inward retraction mechanism, which includes a vertical shaft rotatably mounted on the guide slide groove, an upper gear and a lower gear fixedly mounted on the vertical shaft, two movable forks slidably mounted on the guide slide groove, inner and outer sliding racks fixedly mounted on the movable forks, the inner and outer sliding racks meshing with the upper gear, an upper docking gear rotatably mounted on the vehicle body, the upper docking gear being provided with a docking groove, and a lower transmission belt wrapped around the upper docking gear and the lower gear, the docking groove being used to cooperate with the docking gear.

[0013] Furthermore, the lifting plate is provided with a rotating mechanism, which includes two side gears rotatably mounted on the lifting plate, a lower side gear fixedly mounted on the side gears, and two sets of external transmission belts wound around the lifting plate. The external transmission belts mesh with the lower side gears. When the electric cylinder extends, the lifting gears mesh with the side gears. A rotating fork plate is rotatably mounted on the moving fork, and a rotating gear is fixedly mounted on the rotating fork plate. An external rotating gear is rotatably mounted on the moving fork, and a double-tooth transmission belt is wound around the external rotating gear and the rotating gear. The double-tooth transmission belt meshes with the external transmission belt.

[0014] When the electric cylinder extends, it drives the lifting motor frame and the rotating motor to descend. The lifting gear meshes with the side gear, and the rotating motor rotates, which drives the lifting gear to rotate, which in turn drives the side gear to rotate. This drives the outer transmission belt to rotate through the lower side gear, which in turn drives the outer rotating gear to rotate, which in turn drives the rotating gear and the rotating fork plate to rotate. This adjusts the angle between the rotating fork plate and the moving fork, and the two rotating fork plates rotate in the same direction, which can accommodate more pick-up and put-down angles.

[0015] When the electric cylinder retracts, it drives the lifting gear to rise, and the mating teeth insert into the mating groove. At this time, the rotating motor rotates, driving the lifting gear to rotate. This, in turn, drives the upper mating gear to rotate through the mating teeth. This, in turn, drives the lower gear and the vertical shaft to rotate through the lower transmission belt, which in turn drives the upper gear to rotate. This causes the two inner and outer sliding racks and the moving fork to slide inward or outward along the guide groove simultaneously, thereby adjusting the distance between the two moving forks to accommodate goods of different widths.

[0016] When the mating teeth engage with the mating slots, the outer drive belt is in a free state. When the two moving forks move, the outer drive belt requires more force to drive the double-tooth drive belt than the double-tooth drive belt drives the outer drive belt. Therefore, the double-tooth drive belt will drive the outer drive belt to rotate freely, while the double-tooth drive belt will not rotate.

[0017] The advantages of this invention compared with the prior art are: (1) The mobile device set in this invention can drive the stacker to move and achieve steering through the steering mechanism. The steering limit of the vehicle body is limited by the limit block to prevent the movement direction from being confused due to excessive rotation of the steering wheel; (2) The center of gravity mechanism set in this invention allows the sliding frame to extend when the end device is raised, so that the stacker can maintain balance when the lifting plate lifts the goods, preventing the vehicle from tipping over and causing personnel or goods to fall; (3) The rotating mechanism set in this invention can adjust the angle between the rotating fork plate and the moving fork, and the two rotating fork plates rotate in the same direction, which can adapt to more pick-up and put-down angles; (4) The retracting mechanism set in this invention can drive the two inner and outer sliding racks and the moving fork to slide inward or outward along the guide groove at the same time to adjust the distance between the two moving forks, so as to be suitable for goods of different widths.

Detailed Implementation

[0031] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0032] Example: Reference Figures 1-12 A fall-prevention aisle stacker crane includes a moving device, which includes a vehicle body 101. The moving device is used to move the stacker crane. The moving device is equipped with a drive device and an end device. The drive device includes a lifting motor 201, which is fixedly installed on the vehicle body 101. The end device includes a lifting plate 301, on which a lifting slider 302 is fixedly installed. The lifting slider 302 is slidably installed on the vehicle body 101. The end device is used to lift or lower goods.

[0033] like Figure 3 , Figure 4As shown, the mobile device includes a traveling gear 103 fixedly mounted on the motor shaft of the traveling motor 102, a traveling shaft 106 rotatably mounted on the vehicle body 101, two traveling wheels 105 fixedly mounted on the traveling shaft 106, a traveling transmission belt 104 wrapped around the traveling gear 103 and the traveling shaft 106, and a seat provided on the vehicle body 101.

[0034] like Figure 3 , Figure 4 As shown, a steering mechanism is provided on the vehicle body 101. The steering mechanism includes a steering wheel 107 rotatably mounted on the vehicle body 101, an active rotating frame 108 fixedly mounted on the steering wheel 107, an upper cross shaft 109 rotatably mounted on the active rotating frame 108, an intermediate rotating frame 110 rotatably mounted on the upper cross shaft 109, a lower cross shaft 111 rotatably mounted on the intermediate rotating frame 110, and a vertical rotating shaft 112 rotatably mounted on the lower cross shaft 111. The vertical rotating shaft 112 rotates with the vehicle body 101. The vehicle body 101 is equipped with a rotating shaft 112, a steering gear 113 is fixedly mounted on the shaft, two steering wheel frames 116 are rotatably mounted on the body, a steering wheel 117 is rotatably mounted on the steering wheel frame 116, an outer steering gear 115 is fixedly mounted on the steering wheel frame 116, a steering transmission belt 114 is wound around the two outer steering gears 115 and the steering gear 113, a rotation limit block 119 is fixedly mounted on the steering wheel frame 116, and a limit block 118 is fixedly mounted on the bottom of the body 101.

[0035] The operator sits in the seat of the vehicle body 101. The rotation of the travel motor 102 drives the travel gear 103 to rotate, which in turn drives the travel shaft 106 and travel wheel 105 to rotate via the travel transmission belt 104, thereby enabling the vehicle body 101 to move. The operator rotates the steering wheel 107 to drive the active rotating frame 108 to rotate, which in turn drives the vertical rotating shaft 112 to rotate via the upper cross shaft 109, the middle rotating frame 110, and the lower cross shaft 111, thereby driving the steering gear 113 to rotate. The steering transmission belt 114 drives the outer steering gear 115 and the steering wheel frame 116 to rotate, which in turn drives the steering wheel 117 to rotate, thus enabling the vehicle body 101 to turn. When the steering wheel frame 116 rotates, it will drive the steering limit block 119 to rotate as well. When the steering limit block 119 contacts the limit block 118, it will be blocked by the limit block 118. At this time, the steering wheel frame 116 cannot continue to rotate, thereby limiting the steering limit of the vehicle body 101 and preventing the movement direction from becoming chaotic due to excessive rotation of the steering wheel 107.

[0036] like Figure 5 , Figure 6As shown, the drive device includes a motor gear 202 fixedly mounted on the motor shaft of the lifting motor 201, an internal gear 204 rotatably mounted on the vehicle body 101, an external mating gear 203 fixedly mounted on the internal gear 204, the external mating gear 203 meshing with the motor gear 202, an intermediate gear 206 and an external belt gear 207 rotatably mounted on the vehicle body 101, a mating gear 208 fixedly mounted on the external belt gear 207, and a long transmission belt 205 wrapped around the external belt gear 207, the intermediate gear 206 and the internal gear 204.

[0037] like Figure 5 , Figure 6 As shown, a center of gravity mechanism is provided on the vehicle body 101. The center of gravity mechanism includes a sliding frame 212 slidably installed at the bottom of the vehicle body 101, a sliding rack 213 fixedly installed on the sliding frame 212, two sliding rollers 214 rotatably installed on the sliding frame 212, an inner lower gear 210 rotatably installed on the vehicle body 101, a center of gravity adjusting gear 211 fixedly installed on the inner lower gear 210, and a vertical transmission belt 209 is wound around the inner lower gear 210 and the intermediate gear 206. The center of gravity adjusting gear 211 meshes with the sliding rack 213.

[0038] The lifting motor 201 rotates, driving the motor gear 202 to rotate, which in turn drives the outer docking gear 203 and the inner gear 204 to rotate. Through the long transmission belt 205, the intermediate gear 206 and the outer belt gear 207 rotate, thereby driving the docking gear 208 to rotate. This causes the lifting rack 324 and the lifting plate 301 to rise, which is used to lift the goods. The intermediate gear 206 drives the inner lower gear 210 and the center of gravity adjustment gear 211 to rotate through the vertical transmission belt 209, thereby causing the sliding rack 213 and the sliding frame 212 to slide along the vehicle body 101. The sliding roller 214 rolls on the ground, causing the sliding frame 212 to move towards the lifting plate 301. This ensures that the stacker crane remains balanced when the lifting plate 301 lifts the goods, preventing the crane from tipping over and causing personnel or goods to fall.

[0039] like Figures 7-12 As shown, the end device includes a guide groove 304 fixedly installed on the lifting plate 301, a lifting rack 324 fixedly installed on the lifting plate 301, the lifting rack 324 meshing with the mating gear 208, an electric cylinder 303 fixedly installed on the lifting plate 301, a lifting motor frame 312 fixedly installed on the top of the electric cylinder 303, the lifting motor frame 312 slidingly installed with the lifting plate 301, a rotating motor 313 fixedly installed on the lifting motor frame 312, a lifting gear 314 fixedly installed on the motor shaft of the rotating motor 313, and a mating gear 315 provided on the lifting gear 314.

[0040] like Figures 7-12As shown, an inward retraction mechanism is provided on the guide slide 304. The inward retraction mechanism includes a vertical shaft 307 rotatably mounted on the guide slide 304. An upper gear 306 and a lower gear 309 are fixedly mounted on the vertical shaft 307. Two movable forks 308 are slidably mounted on the guide slide 304. Inner and outer sliding racks 305 are fixedly mounted on the movable forks 308. The inner and outer sliding racks 305 mesh with the upper gear 306. An upper docking gear 319 is rotatably mounted on the vehicle body 101. A docking groove 320 is provided on the upper docking gear 319. A lower transmission belt 310 is wound around the upper docking gear 319 and the lower gear 309. The docking groove 320 is used to cooperate with the docking gear 315.

[0041] like Figures 7-12 As shown, a rotating mechanism is provided on the lifting plate 301. The rotating mechanism includes two side gears 316 rotatably mounted on the lifting plate 301. A lower side gear 317 is fixedly mounted on the side gears 316. Two sets of external transmission belts 318 are wound on the lifting plate 301. The external transmission belts 318 mesh with the lower side gears 317. When the electric cylinder 303 extends, the lifting gear 314 meshes with the side gears 316. A rotating fork plate 311 is rotatably mounted on the moving fork 308. A rotating gear 323 is fixedly mounted on the rotating fork plate 311. An external rotating gear 321 is rotatably mounted on the moving fork 308. A double-tooth transmission belt 322 is wound around the external rotating gear 321 and the rotating gear 323. The double-tooth transmission belt 322 meshes with the external transmission belt 318.

[0042] When the electric cylinder 303 extends, it drives the lifting motor frame 312 and the rotating motor 313 to descend. The lifting gear 314 meshes with the side gear 316. The rotating motor 313 rotates, driving the lifting gear 314 to rotate, which in turn drives the side gear 316 to rotate. This drives the outer transmission belt 318 to rotate through the lower side gear 317, which in turn drives the outer rotating gear 321 to rotate, which in turn drives the rotating gear 323 and the rotating fork plate 311 to rotate. This adjusts the angle between the rotating fork plate 311 and the moving fork 308. The two rotating fork plates 311 rotate in the same direction, which can accommodate more pick-up and put-down angles.

[0043] When the electric cylinder 303 retracts, it drives the lifting gear 314 to rise, and the mating teeth 315 are inserted into the mating groove 320. At this time, the rotating motor 313 rotates, driving the lifting gear 314 to rotate. The mating teeth 315 drive the upper mating gear 319 to rotate, which in turn drives the lower gear 309 and the vertical shaft 307 to rotate via the lower transmission belt 310. This, in turn, drives the upper gear 306 to rotate, thereby causing the two inner and outer sliding racks 305 and the moving fork 308 to slide inward or outward simultaneously along the guide groove 304 to adjust the distance between the two moving forks 308 to accommodate goods of different widths.

[0044] When the mating teeth 315 engage with the mating groove 320, the outer drive belt 318 is in a free state. When the two moving forks 308 move, the outer drive belt 318 requires more force to drive the double toothed drive belt 322 than the double toothed drive belt 322 drives the outer drive belt 318. Therefore, the double toothed drive belt 322 will drive the outer drive belt 318 to rotate freely, while the double toothed drive belt 322 will not rotate.

[0045] The working principle of the anti-fall stacker crane disclosed in this invention is as follows: The operator sits on the seat of the vehicle body 101. The travel motor 102 rotates, driving the travel gear 103 to rotate. Through the travel transmission belt 104, the travel shaft 106 and the travel wheel 105 rotate, thereby realizing the movement of the vehicle body 101. Rotating the steering wheel 107 drives the active rotating frame 108 to rotate, which in turn drives the vertical rotating shaft 112 to rotate through the upper cross shaft 109, the intermediate rotating frame 110 and the lower cross shaft 111, thereby driving the steering gear. When the steering wheel 113 rotates, it drives the outer steering gear 115 and the steering wheel frame 116 to rotate via the steering transmission belt 114, thereby driving the steering wheel 117 to rotate and realizing the steering of the vehicle body 101. When the steering wheel frame 116 rotates, it will drive the steering limit block 119 to rotate together. When the steering limit block 119 contacts the limit block 118, it will be blocked by the limit block 118. At this time, the steering wheel frame 116 cannot continue to rotate, thereby limiting the steering limit of the vehicle body 101 and preventing the movement direction from becoming chaotic due to excessive rotation of the steering wheel 107. The lifting motor 201 rotates, driving the motor gear 202 to rotate, which in turn drives the outer docking gear 203 and the inner gear 204 to rotate. Through the long transmission belt 205, the intermediate gear 206 and the outer belt gear 207 rotate, thereby driving the docking gear 208 to rotate. This causes the lifting rack 324 and the lifting plate 301 to rise, which is used to lift the goods. The intermediate gear 206 drives the inner lower gear 210 and the center of gravity adjustment gear 211 to rotate through the vertical transmission belt 209, thereby causing the sliding rack 213 and the sliding frame 212 to slide along the vehicle body 101. The sliding roller 214 rolls on the ground, causing the sliding frame 212 to move towards the lifting plate 301. This ensures that the stacker crane remains balanced when the lifting plate 301 lifts the goods, preventing tipping. When the electric cylinder 303 extends, it drives the lifting motor frame 312 and the rotating motor 313 to descend. The lifting gear 314 meshes with the side gear 316. The rotating motor 313 rotates, driving the lifting gear 314 to rotate, which in turn drives the side gear 316 to rotate. This drives the outer transmission belt 318 to rotate through the lower side gear 317, which in turn drives the outer rotating gear 321 to rotate, which in turn drives the rotating gear 323 and the rotating fork plate 311 to rotate. This adjusts the angle between the rotating fork plate 311 and the moving fork 308. The two rotating fork plates 311 rotate in the same direction, which can accommodate more pick-up and put-down angles. When the electric cylinder 303 retracts, it drives the lifting gear 314 to rise, and the mating teeth 315 are inserted into the mating groove 320. At this time, the rotating motor 313 rotates, driving the lifting gear 314 to rotate. The mating teeth 315 drive the upper mating gear 319 to rotate, which in turn drives the lower gear 309 and the vertical shaft 307 to rotate via the lower transmission belt 310. This, in turn, drives the upper gear 306 to rotate, thereby causing the two inner and outer sliding racks 305 and the moving fork 308 to slide inward or outward simultaneously along the guide groove 304 to adjust the distance between the two moving forks 308 to accommodate goods of different widths.
