Description

Technical Field

[0001] This utility model relates to the field of stacker crane technology, and in particular to a gear and rack drive device suitable for the vertical lifting of stacker cranes. Background Technology

[0002] Stacker cranes are the core equipment of the entire automated warehouse. They can move goods from one place to another through manual, semi-automatic, and fully automatic operation. Traditional stacker cranes usually rely on the friction between the wheels and the ground rails to achieve horizontal movement. Since the columns in large warehouses are usually quite tall, when the lower part of the stacker crane is driven to move, the upper part will generate strong vibrations, which will affect the reliability and safety of the equipment.

[0003] Stacker cranes typically operate in warehouse environments, where there are large quantities of goods and packaging materials. Dust is generated during the handling and storage of goods, and this dust falls onto the gears and racks. This accelerates the wear between the gears and racks, causing positional deviations during the vertical lifting and lowering of the stacker crane. As a result, the stacker crane cannot accurately stop at the designated position, affecting the accurate loading and unloading of goods and reducing the working efficiency and reliability of the stacker crane. Utility Model Content

[0007] Preferably, a nozzle is fixedly connected to the bottom of the cylinder, a one-way valve is fixedly connected to the nozzle, and an air jet hood is fixedly connected to the end of the nozzle away from the cylinder.

[0008] Preferably, a second groove is provided on the side of the fixing bar away from the slider, a slide plate is slidably connected in the second groove, and a fixing rod is fixedly connected on the side of the slide plate away from the second groove.

[0011] The beneficial effects of this utility model are as follows:

[0012] In this utility model:

[0013] 1. When the device is needed, start the drive motor. The drive motor drives the rotating shaft and gear to rotate. The gear meshes with the rack, which in turn causes the device to rotate vertically. During the rotation of the rotating shaft, the second circular plate rotates. After the second circular plate rotates, it drives the connecting rod to rotate. During the rotation of the connecting rod, the connecting rod pulls the piston plate to move up and down inside the cylinder through the connecting bar. When the piston plate moves downward, it can push the gas entering the cylinder into the nozzle. The gas entering the nozzle is then blown onto the gear and rack through the jet hood, thereby cleaning the dust that falls on the surface of the gear and rack. This helps to keep the gear and rack clean, reduce the impact of dust on their meshing accuracy, reduce wear, extend service life, and at the same time ensure the smoothness and reliability of the device's lifting and lowering movement.

[0014] 2. When the connecting bar drives the piston plate to move upward inside the cylinder, the nozzle is restricted by the second one-way valve, and at this time the nozzle is in a closed state. The air inlet pipe is restricted by the first one-way valve. The piston plate moves upward to draw gas from the air inlet pipe into the cylinder. The gas is filtered by the air filter hood, which can filter dust and impurities in the gas. This prevents the gas blown towards the gears and rack from containing new dust, prevents secondary pollution of the already cleaned gears and racks, ensures the cleaning effect, and helps maintain the cleanliness of the gears and racks.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-6 The diagram illustrates a rack and pinion drive device suitable for the vertical lifting of a stacker crane. It includes a fixed bar 101, which further includes a drive mechanism 1. A groove 102 is formed on the side wall of the fixed bar 101, and a slider 103 is slidably connected within the groove 102. A drive motor 104 is fixedly connected to the side wall of the slider 103. A rotating shaft 105 is fixedly connected to the output shaft of the drive motor 104, passing through the slider 103 and rotatably connected to it. A gear 106 is fixedly connected to the end of the rotating shaft 105 away from the drive motor 104. A gear 106 is also fixedly connected to the side wall of the fixed bar 101. A rack 107 is connected, which meshes with a gear 106. A fixed sleeve 108 is fixedly connected to the bottom of the slider 103. A cylinder 109 is fixedly connected to the inner wall of the fixed sleeve 108. An air inlet pipe 110 is fixedly connected to the bottom of the cylinder 109. A one-way valve 111 is fixedly connected to the air inlet pipe 110. A filter hood 112 is fixedly connected to the end of the air inlet pipe 110 away from the cylinder 109. A nozzle 113 is fixedly connected to the bottom of the cylinder 109. A one-way valve 114 is fixedly connected to the nozzle 113. A jet nozzle hood 115 is fixedly connected to the end of the nozzle 113 away from the cylinder 109.

[0024] When the device is needed, the drive motor 104 is started, which drives the rotating shaft 105 and gear 106 to rotate. The gear 106 meshes with the rack 107, causing the device to rotate vertically. During the rotation of the rotating shaft 105, the circular plate 120 rotates, which in turn drives the connecting rod 121 to rotate. During the rotation of the connecting rod 121, the piston plate 123 is pulled up and down inside the cylinder 109 by the connecting bar 122. When the piston plate 123 moves downward, it can push the gas entering the cylinder 109 into the nozzle 113. The gas entering the nozzle 113 is then blown onto the gear 106 and rack 107 through the jet hood 115, thereby cleaning the dust that falls on the surface of the gear 106 and rack 107. This helps to keep the gear 106 and rack 107 clean, reduces the impact of dust on their meshing accuracy, reduces wear, extends service life, and also ensures the smoothness and reliability of the device's lifting and lowering movement.

[0025] A second groove 116 is provided on the side of the fixed bar 101 away from the slider 103. A slide plate 117 is slidably connected in the second groove 116. A fixed rod 118 is fixedly connected on the side of the slide plate 117 away from the second groove 116. A circular plate 119 is rotatably connected to the end of the fixed rod 118 away from the slide plate 117. A circular plate 120 is fixedly connected to the end of the rotating shaft 105 away from the drive motor 104. A connecting rod 121 is fixedly connected to the side of the circular plate 120 and the circular plate 119 that are close to each other. A connecting bar 122 is rotatably connected to the outer wall of the connecting rod 121. A piston plate 123 is slidably connected to the inner wall of the cylinder 109. A connecting block 124 is fixedly connected to the top of the piston plate 123. The top of the connecting block 124 is rotatably connected to the connecting bar 122.

[0026] When the connecting bar 122 drives the piston plate 123 to move upward inside the cylinder 109, the nozzle 113 is restricted by the second check valve 114. At this time, the nozzle 113 is in a closed state, and the air inlet pipe 110 is restricted by the first check valve 111. The piston plate 123 moves upward to draw gas from the air inlet pipe 110 into the cylinder 109. The gas is filtered by the air filter hood 112, which can filter dust and impurities in the gas. This prevents the gas blown towards the gear 106 and rack 107 from containing new dust, prevents secondary pollution of the already cleaned gear 106 and rack 107, ensures the cleaning effect, and helps maintain the cleanliness of the gear 106 and rack 107.

[0027] The working principle of the gear and rack drive device for vertical lifting of a stacker crane provided by this utility model is as follows: When the device is needed, the drive motor 104 is started. The drive motor 104 drives the rotating shaft 105 and the gear 106 to rotate. The gear 106 meshes with the rack 107, thereby causing the gear 106 to rotate and drive the device to lift vertically. During the rotation of the rotating shaft 105, the circular plate 120 rotates. After the circular plate 120 rotates, it drives the connecting rod 121 to rotate. During the rotation of the connecting rod 121, the piston plate 123 is pulled up and down in the cylinder 109 through the connecting bar 122. When the piston plate 123 moves downward, it can push the gas entering the cylinder 109 into the nozzle 113. The gas entering the nozzle 113 is then blown towards the gear 106 and the rack through the jet hood 115.

[0028] When the connecting bar 122 drives the piston plate 123 to move upward inside the cylinder 109, the nozzle 113 is restricted by the second check valve 114. At this time, the nozzle 113 is in a closed state, and the air inlet pipe 110 is restricted by the first check valve 111. The piston plate 123 moves upward to draw gas from the air inlet pipe 110 into the cylinder 109. The gas is filtered by the air filter hood 112, which can filter dust and impurities in the gas. This prevents the gas blown towards the gear 106 and rack 107 from containing new dust and prevents secondary pollution to the already cleaned gear 106 and rack 107.

[0029] Compared with related technologies, the gear and rack drive device for vertical lifting of stacker cranes provided by this utility model has the following advantages:

[0030] This utility model provides a gear and rack drive device suitable for the vertical lifting of a stacker crane. When the device is needed, the drive motor 104 is started, which drives the rotating shaft 105 and the gear 106 to rotate. The gear 106 meshes with the rack 107, thereby causing the gear 106 to rotate and drive the device to lift vertically. During the rotation of the rotating shaft 105, the circular plate 120 rotates. After the circular plate 120 rotates, it drives the connecting rod 121 to rotate. During the rotation of the connecting rod 121, the piston plate 123 is pulled through the connecting bar 122. The piston plate 123 moves up and down inside the cylinder 109. When it moves downward, it can push the gas entering the cylinder 109 into the nozzle 113. The gas entering the nozzle 113 is then blown onto the gear 106 and rack 107 through the jet hood 115, thereby cleaning the dust that falls on the surface of the gear 106 and rack 107. This helps to keep the gear 106 and rack 107 clean, reduce the impact of dust on their meshing accuracy, reduce wear, extend service life, and at the same time ensure the smoothness and reliability of the lifting and lowering movement of the device.

[0031] When the connecting bar 122 drives the piston plate 123 to move upward inside the cylinder 109, the nozzle 113 is restricted by the second check valve 114. At this time, the nozzle 113 is in a closed state, and the air inlet pipe 110 is restricted by the first check valve 111. The piston plate 123 moves upward to draw gas from the air inlet pipe 110 into the cylinder 109. The gas is filtered by the air filter hood 112, which can filter dust and impurities in the gas. This prevents the gas blown towards the gear 106 and rack 107 from containing new dust, prevents secondary pollution of the already cleaned gear 106 and rack 107, ensures the cleaning effect, and helps maintain the cleanliness of the gear 106 and rack 107.
