Description

Technical Field

[0001] This invention relates to a roadway stacker crane, specifically to a light-load, high-speed roadway stacker crane. Background Technology

[0002] Chinese patent application number 202410985854.3 discloses a high-speed bin stacker crane, comprising: a base box, with a vertical frame fixedly connected to the top of the base box, a sliding seat slidably sleeved on the outer side of the vertical frame, a support plate fixedly installed on one side of the sliding seat, and guide rails fixedly connected to both the front and rear sides of the bottom of the base box; a drive mechanism for driving the sliding seat to rise and fall, the drive mechanism including a lifting motor and a lead screw, the lead screw being fixedly connected to the output shaft of the lifting motor, and the sliding seat being threadedly sleeved on the outer side of the lead screw; and a counterweight mechanism for adjusting the center of gravity position of the base box, the counterweight mechanism including a vertical shaft, two counterweight plates, an adjusting plate, a rotating arm, and two adjusting screws. This invention, through the cooperation of the counterweight mechanism and the triggering mechanism, can automatically adjust the center of gravity during the movement of the stacker crane to ensure safety and meet the needs of high-speed operation. Furthermore, it can more quickly and efficiently adjust the center of gravity position when the stacker crane's center of gravity rises due to cargo, to meet different needs.

[0003] However, the Chinese patent with application number 202410985854.3 states that the glass bottles collide during stacking, affecting their stacking speed.

[0004] Chinese patent application number 202510616689.9 discloses a water bottle stacking device, including a slide rail fixedly installed on a support platform, forks slidably engaged on the slide rail, and a self-locking drive mechanism installed on the support platform for driving the forks to reciprocate. The forks include a sliding fork and a support fork elastically slidably disposed, and the self-locking drive mechanism drives the sliding fork to reciprocate. A column is fixedly installed on the support fork. In this invention, the action of reinforcing the packaged water bottles is achieved during the process of the self-locking drive mechanism driving the forks to retract the packaged water bottles onto the support platform. The two actions are seamlessly connected, requiring no operator intervention, no separate drive for the pressing component, and no separate control system. This saves costs and reduces the design complexity of the control system while effectively reducing the connection time between the two actions to improve work efficiency.

[0005] However, the Chinese patent with application number 202510616689.9 has a complex structure, making it difficult to promote and use.

[0006] Therefore, it is necessary to provide new technical solutions to overcome the above-mentioned defects. Summary of the Invention

[0008] To achieve the objectives of this invention, the following technical solution is adopted: The stacker crane includes: a ground rail, a overhead rail, forks, a traveling mechanism, and an electrical control box. The control box contains an information acquisition terminal, a data processing terminal, and an instruction generation terminal. These three terminals are electrically connected. The information acquisition terminal acquires the pressure on the sides of the stacker. If the pressure on both sides of the stacker is high, it indicates that the stacker is clamped and fixed by the pressure from both sides. The data processing terminal determines whether the stacker is clamped based on the pressure on its sides. The instruction generation terminal generates a clamping instruction based on whether the stacker is clamped.

[0009] Furthermore: the fork includes: a fixed groove, a plurality of gears installed inside the fixed groove, a support plate sliding on the fixed groove, and a first rack fixedly installed below the support plate, the first rack meshing with the gears.

When the rotating member contacts the surface of the protrusion, it will drive the central member to move towards the center.

[0013] Furthermore: the rotating member is composed of a contact part, a connecting part and an abutting part, the contact part is eccentric and has a protrusion at one end near the converging member.

[0014] Furthermore: the concentrator is composed of a vertical plate, a mounting plate, a guide rod, a bushing, and a movable plate, and the mounting plate is fixedly connected to the vertical plate.

[0015] Furthermore: the movable plates are provided in multiple sets, and each set has two plates. The movable plates are provided with half holes, and a set of movable plates forms a cavity to position the bottle.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0030] like Figures 1 to 9 As shown, the stacker crane of the present invention includes: a ground rail 1, a ceiling rail 2, forks 3, a traveling mechanism 4, and an electrical control box 5.

[0031] The walking mechanism 4 includes: a base plate 6, walking wheels 7, and brushes 8; the walking wheels 7 are mounted on the base plate 6, and a walking motor 9 that drives the walking wheels 7 to move actively is connected to the walking wheels 7; a cable is installed on the outside of the ground rail 1, and the cable slides in contact with the ground rail; the brushes 8 are used to draw power, and the brushes 8 are electrically connected to the walking motor 9.

[0032] The cable is electrically connected to the mains power supply to power the stacker crane of the present invention. The cable draws power and the walking motor 9 drives the walking wheels 7 to move, thereby moving the base plate 6.

[0033] A plurality of first guide wheels are rotatably connected to the base plate 6. The first guide wheels are located on both sides of the ground rail 1, and the first guide wheels enable the base plate 6 to move stably.

[0034] A column 10 is fixedly connected to the base plate 6. The column 10 is equipped with a lifting mechanism 11 that drives the forks 3 to rise and fall. A contact wheel and a second guide wheel are rotatably installed on the upper end of the column 10.

[0035] The contact wheel contacts the lower surface of the overhead track 2. At least two second guide wheels are provided and are evenly distributed on both sides of the overhead track 2. The contact wheel, the first guide wheel, and the second guide wheel work together to enable the roadway stacker crane of the present invention to move stably.

[0036] The lifting mechanism 11 includes a movable frame 12, a traction motor 13, a traction sheave 14, and a pulley 15. One end of the cable is fixed to the traction sheave 14, and the other end of the cable is fixedly connected to the movable frame 12. The traction motor 13 is connected to the traction sheave 14, and the traction motor 13 drives the traction sheave 14 to rotate, so that the cable is wound on the traction sheave 14. The pulley 15 is rolled and installed on the top of the column 10. The pulley 15 is used to change the direction of movement of the cable. In this application, the cable is preferably a steel wire rope.

[0037] In order to make the movable frame 12 move stably, a plurality of third guide wheels 16 are rotatably mounted on one side of the movable frame 12. The third guide wheels 16 roll in contact with the column 10 and the third guide wheels 16 contact at least three surfaces of the column 10, thereby enabling the movable frame 12 to move up and down stably.

[0038] The control box is equipped with an information acquisition terminal, a data processing terminal, and an instruction generation terminal, which are electrically connected.

[0039] In one usage scenario, the information acquisition end obtains the height of the fork 3, the data processing end determines which shelf the fork 3 is on based on the height of the fork 3, and the instruction generation end generates an instruction for the fork 3 to rise or fall.

[0040] In another use case, the information acquisition end acquires the pressure on the side of the box. If the pressure on both sides of the box is large, it indicates that the box is clamped and fixed by the pressure from both sides. The data processing end determines whether the box is clamped based on the pressure on the side of the box. The instruction generation end generates a clamping instruction based on whether the box is clamped.

[0041] The fork 3 includes: a fixed groove 17, a plurality of gears installed inside the fixed groove 17, a support plate 20 sliding on the fixed groove 17, and a first rack 21 fixedly installed below the support plate 20. The first rack 21 meshes with the gears, so that the gears can drive the first rack 21 to move, thereby driving the support plate 20 to move.

[0042] It should be noted that a drive motor 22 is installed on the fixing slot 17, and the drive motor 22 drives the gear to rotate through a connecting mechanism. The gear is divided into a drive gear 18 and a connecting gear 19. The connecting gear 19 meshes with the drive gear 18, and the drive gear 18 meshes with the first rack 21. In this application, four drive gears 18 and four connecting gears 19 are provided. The purpose of providing multiple drive gears 18 is to ensure the stable movement of the first rack 21.

[0043] In actual use, the fork 3 is provided with a lateral fixing mechanism, which includes: a lateral motor 23, a lateral gear 24 connected to the output shaft of the lateral motor 23, a second rack 25 meshing with the lateral gear 24, a side pusher 26 connected to the second rack 25, and a lateral clamping plate 27 connected to the side pusher 26.

[0044] In this application, the lateral fixing mechanism is provided in four sets, which are located at the four corners of the box and fix the box on both sides. The lateral motor 23 drives the lateral gear 24 to rotate, thereby causing the lateral gear 24 to drive the second rack 25 to move, so that the lateral clamp 27 contacts the box.

[0045] In order to make the side pusher 26 move stably, a first slider 28 is fixedly connected to the side pusher 26. The first slider 28 is slidably disposed on the first guide rail 29. The first guide rail 29 and the first slider 28 can make the side pusher 26 slide stably.

[0046] In one embodiment, a pressure sensor is fixedly installed on the lateral clamping plate 27 to detect the clamping force between the lateral clamping plate 27 and the housing. The clamping force has a preset threshold. When the value detected by the pressure sensor does not reach the preset threshold, the lateral motor 23 drives the lateral gear 24 to rotate. If the value detected by the pressure sensor reaches the preset threshold, the lateral motor 23 stops driving the lateral gear 24 to rotate.

[0047] To ensure a more secure fixation of the housing, this application includes a pressing mechanism comprising: a downwardly moving pressure plate 30; a power component that drives the pressure plate 30 downward; a centering member 32 slidably mounted on the pressure plate 30; a rotating member 33 hinged to the centering member 32; a torsion spring between the rotating member 33 and the centering member 32; and a protrusion 331 fixed inside the housing. When the power component moves downward, it drives the centering member 32 downward. When the rotating member 33 contacts the surface of the protrusion 331, it drives the centering member 32 to move towards the center, causing the torsion spring to be stressed. When the rotating member 33 disengages from the protrusion 331, the torsion spring rebounds.

[0048] The power component described in this application can be an electric actuator, which is mounted on the bracket 31.

[0049] It should be noted that the rotating member 33 consists of a contact portion 34, a connecting portion 35, and an abutting portion 36. The lower surface of the abutting portion 36 is flat, allowing it to better contact the protrusion 331. The connecting portion 35 connects the contact portion 34 and the abutting portion 36. The contact portion 34 is eccentric, with a protrusion 37 at one end near the converging member 32, which can push the converging member 32 towards the center during rotation.

[0050] In actual use, a second slider is fixedly connected to the upper end of the centering member 32, and a second guide rail is fixedly connected to the pressure plate 30. The second slider slides in contact with the second guide rail, thereby guiding the movement of the centering member 32.

[0051] The concentrator 32 consists of a vertical plate 38, a mounting plate 39, a guide rod 43, a bushing 40, and a movable plate 41. The rotating component 33 is located in the middle of the vertical plate 38, and the mounting plate 39 is fixedly connected to the vertical plate 38. Multiple sets of movable plates 41 are provided, with two plates in each set. Each movable plate 41 has a semi-hole 42. A set of movable plates 41 forms a cavity for positioning the bottle.

[0052] It should be explained in detail here that the guide rod 43 is fixedly connected to the mounting plate 39 on one side, and the guide rod 43 is slidably connected to the mounting plate 39 on the other side; the moving plate 41 is provided with bushings 40 at both ends, one of which is fixedly connected to the guide rod 43, and the other is slidably connected to the guide rod 43.

[0053] In detail, the guide rod 43 has two functions: first, to guide and position the moving plate 41 so that it can move along the axial direction of the guide rod 43; second, to connect multiple moving plates 41. Multiple moving plates 41 can be connected through the guide rod 43 and the bushing 40 fixedly connected to the guide rod 43.

[0054] It is not difficult to see from the above description that the bushing 40 and the guide rod 43 in this application can play a role in mutual positioning; when the pressure plate 30 moves downward, it drives the centering member 32 to move downward, and under the action of the rotating member 33, the centering member 32 moves towards the middle. Thus, this application can achieve downward movement and center movement at the same time through a power source.

[0055] The information acquisition terminal acquires the pressure on the side of the box. If the pressure on both sides of the box is large, it means that the box is clamped and fixed by the pressure from both sides.
