Description

Technical Field

[0001] The utility model relates to the technical field of stackers, in particular to a heavy-load stacker for a stereoscopic warehouse. Background Art

[0002] In modern logistics and industrial industries, warehouses with very large areas are often needed to organize items. At the same time, in the goods entering and leaving the warehouse, because the weight of the items is very heavy, ordinary workers find it difficult to lift the weight of the items, and usually stackers are needed to replace the role of manual labor to transfer items. The emergence of heavy-duty stackers has greatly liberated the physical strength of manual labor and increased work efficiency.

[0003] Chinese patent CN216863553U discloses a side guide wheel mechanism for a cargo platform dedicated to a heavy-duty stacker, including a device body, two mounting plates installed on the upper part of the device body, a carrying assembly slidably connected between the two mounting plates, a lifting drive assembly driving the carrying assembly to rise and fall is arranged on the upper part of the mounting plate, two fixed plates are installed on the device body, a first roller is rotatably connected between the two fixed plates via a rotating shaft, and the utility model drives the first roller to rotate by setting a first motor, and then uses the first roller to receive a first pull rope, so that the first pull rope can pull the end of the carrying assembly that is tilted due to the gravity of the goods, thereby balancing the weight of the two ends of the carrying assembly, increasing the service life of the side wheels and the mounting plates, and improving the stability of the carrying assembly. However, there are still defects that are sufficient to be improved:

[0004] 1. The transport component of the utility model only has rollers and pull ropes. In the actual heavy-duty stacker, overweight items are often encountered. If there is no protective device, the motor is very likely to burn out after overloading, and the pull rope and transport component connected to the motor will slip. At the same time, the goods on the stacker will slide down, causing loss of goods and certain risks to personnel.

[0005] 2. There is no fixing device at the bottom of the device body of the utility model. During the cargo transfer process, when removing the cargo from the cargo rack, the weight of the device body changes, causing the device to shake. This shaking will gradually increase from high to low. If there is no fixing device, the stacker will move, greatly affecting the stability of the heavy-load stacker. Utility Model Content

[0029] The working principle of the present utility model is as Figure 1-Figure 4 shown. A heavy-duty stacker for a three-dimensional warehouse includes a base 1. On both sides of the middle of the top of the base 1, support columns 2 are fixedly connected. At the rear of both sides of the top of the base 1, a first motor 3 is provided. The first motor 3 is fixedly connected to the base 1 through a motor base 20. A rotating shaft 4 is fixedly connected to the output shaft of the first motor 3. At the front ends of the two rotating shafts 4, a baffle 6 is rotatably connected. The bottom end of the baffle 6 is fixedly connected to the base 1. The top of the support column 2 is fixedly connected to a support plate 14. A through groove 15 is opened in the middle of the top of the support plate 14. On both sides above the through groove 15, drums 16 are provided. The two drums 16 are fixedly connected to the support plate 14. On both sides of the support plate 14, drums 17 are provided. Here, both the drum 16 and the drum 17 function as fixed pulleys. On both rotating shafts 4, ropes 5 are provided. One end of the rope 5 away from the rotating shaft 4 sequentially bypasses the drum 17 and the drum 16 and finally a lifting wheel 10 is provided. On the side where the two lifting wheels 10 are close to each other, a "U"-shaped carrier 8 is provided. On both sides of the middle of the top of the carrier 8, electric telescopic plates 9 are provided. At the same time, a workbench 7 is fixedly connected to the bottom end of the carrier 8. Immediately, on both sides of the top of the workbench 7, a protection device 11 is provided. On both sides of the bottom end of the workbench 7, protection frames 12 are provided. At the same time, pulley groups 13 are provided at the front and rear parts on the side where the two protection frames 12 are separated from each other. The pulley groups 13 are provided to facilitate the smoother upward sliding of the workbench 7. The pulley groups 13 at the front and rear parts on both sides cooperate with the support columns 2. When the first motor 3 rotates, the rope 5 will drive the workbench 7 to move in the vertical direction. Finally, wheels 18 are provided at the front and rear parts on both sides below the base 1. The wheels 18 and the base 1 are interconnected through a brake device 19.

[0030] The above-mentioned various structures together constitute the general appearance structure of a heavy-duty stacker for a three-dimensional warehouse of the present utility model.

[0031] In order to further explain the specific working principle of a heavy-duty stacker for a stereoscopic warehouse of the utility model, the above-mentioned protection device 11 includes a bottom plate 1101 arranged at the middle of both sides of the top of the workbench 7, and the rear ends of the bottom plates 1101 on both sides are fixedly connected to a fixing frame 1107, and then a smooth rod 1104 is rotatably connected to the front end of the fixing frame 1107, and at the same time, the front end of the smooth rod 1104 is fixedly connected to a motor 2 1102. In order to fix the motor 2 1102, a motor seat 2 1103 is arranged at the bottom end of the motor 2 1102 to fix it on the bottom plate 1101. In order to better transmit the power, the front end of the smooth rod 1104 is fixedly connected to the bottom plate 1101. The rear part is respectively provided with a threaded portion 1105 and a threaded portion 2 1106. It is noteworthy that the rotation directions of the threaded portion 1105 and the threaded portion 2 1106 are opposite. Finally, the threaded portion 1105 and the threaded portion 2 1106 are respectively threadedly connected with a speed reducer 1108 and a speed reducer 2 1109. In order to prevent the speed reducer 1108 and the speed reducer 2 1109 from rotating along with the smooth rod 1104 during transmission, the speed reducers 1108 and the speed reducer 2 1109 on both sides are arranged to be slidably connected to the base plate 1101, and at the same time, the adjacent sides of the speed reducer 1108 and the speed reducer 2 1109 are used in conjunction with the support column 2.

[0032] The technical effect achieved by the technical scheme composed of the above-mentioned technical features is: when it is safe, the deceleration plate 1 1108 and the deceleration plate 2 1109 both maintain a certain distance from the support column 2, which is convenient for the up and down movement of the workbench 7; when danger occurs, the motor 2 1102 starts to drive the smooth rod 1104 to rotate together, and at the same time, the threaded part 1105 and the threaded part 2 1106 on the smooth rod 1104 rotate together with the smooth rod 1104, at this time, the deceleration plate 1 1108 and the deceleration plate 2 1109 threadedly connected with the threaded part 1105 and the threaded part 2 1106 respectively start to slide in the direction of the similar side, and when sliding to a certain distance, dry friction occurs between the deceleration plate 1 1108 and the deceleration plate 2 1109 and the support column 2, because the motor 2 1102 is constantly running, that is, the deceleration plate 1 1108 and the deceleration plate 2 1109 have been effectively rubbing with the support column 2, which eventually makes the descending speed of the workbench 7 greatly slow down, and even the workbench 7 hovers.

[0033] In order to further explain the specific working principle of a heavy-duty stacker for a stereoscopic warehouse of the utility model, the brake device 19 includes a rotating base frame 1901 fixedly connected to the bottom end of the base 1, a fixed baffle 1904 is fixedly connected to one side of the rotating base frame 1901, and a wheel frame 1902 is fixedly connected to the side of the bottom end of the rotating base frame 1901 away from the fixed baffle 1904, and then the upper part of the wheel frame 1902 is rotatably connected to a brake pad 1903, and the brake pad 1903 is away from the wheel frame 1 A spring 1907 is hinged on the upper part of one side of 902, and the top of the spring 1907 is hinged on the rotating base frame 1901, and the bottom end of the wheel frame 1902 is connected to the wheel 18, and the wheel 18 rotates on the wheel frame 1902. Finally, a trapezoidal block 1905 is arranged between the brake pad 1903 and the fixed baffle 1904, and the top of the trapezoidal block 1905 is fixedly connected to the hydraulic telescopic cylinder 1906, and the top of the hydraulic telescopic cylinder 1906 is fixedly connected to the bottom end of the rotating base frame 1901.

[0034] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: normally, the hydraulic telescopic cylinder 1906 is in a retracted state. Due to the action of the spring 1907, the brake pad 1903 and the wheel 18 are not in contact. When it is necessary to prevent the device from shifting, the hydraulic telescopic cylinder 1906 begins to extend downward, while driving the trapezoidal block 1905 to move downward. While the trapezoidal block 1905 moves downward, it continuously squeezes the brake pad 1903, so that the brake pad 1903 begins to abut against the wheel 18, and finally the brake pad 1903 completely abuts against the wheel 18, achieving a certain effect of limiting displacement.

[0035] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
