Description

Technical Field

[0001] The utility model relates to the technical field of stackers, in particular to a stacker that can be maintained without climbing to heights. Background Art

[0002] Stackers are mainly used for stacking and retrieving goods in warehouses.

[0003] The traditional fork lift drive system of stackers usually adopts a chain and sprocket structure. Although this structure is simple and reliable, there are some obvious deficiencies in actual use. First of all, the chain and sprocket need to be cleaned and lubricated regularly to prevent wear and failure. This process not only takes time and effort, but also because the chain and sprocket are usually located at a relatively high position, climbing operations are required, which poses a certain safety risk. Summary of the Utility Model

[0004] In order to solve the technical problems in the background art, the utility model discloses a stacker that can be maintained without climbing to heights.

[0005] The utility model provides a stacker that can be maintained without climbing to heights, including a lifting frame and a fork. Vertical and symmetrically arranged racks are provided on the lifting frame;

[0006] Gears driven by a reduction motor are provided at both ends of the fork and are engaged with the racks;

[0007] A hollow air chamber is provided on the lifting frame, and a plurality of air spray holes facing the tooth grooves of the racks are opened on the air chamber;

[0008] After high-pressure air enters the air chamber, it sprays out from the air spray holes to clean the impurities in the tooth grooves of the racks.

[0009] The beneficial effects of the above settings are as follows: 1. The utility model uses a gear and rack to drive the fork to lift. The structure of the rack is simple, and only the tooth grooves of the rack need to be cleaned, thereby reducing the difficulty of maintenance; 2. When cleaning the tooth grooves of the rack, only need to fill high-pressure air into the air chamber. When the high-pressure air sprays out from the air spray holes, it can clean the tooth grooves of the rack, thus avoiding climbing operations; 3. When lubricating the rack, only need to apply lubricating oil on the gear. When the gear rises, the lubricating oil will be automatically coated on the rack, also avoiding climbing operations; 4. Compared with the chain and sprocket structure, the gear and rack drive method has better transmission efficiency and lower failure rate, improving the reliability of the fork lift drive system of the stacker.

[0010] Conventionally, spur gears are used for gears and racks, and sundries are easily accumulated in the tooth grooves of the racks, which will increase the difficulty of cleaning. Based on this, a further improvement lies in: the rack is a helical rack, and the gear is a matching helical gear. With this setting, some impurities will freely fall along the tooth grooves of the rack, thereby reducing the amount of impurities in the tooth grooves of the rack and making cleaning more convenient.

[0011] To improve the lifting stability of the fork, it is necessary to mill the inner side of the lifting frame to improve the installation accuracy of the rack. This not only has a high labor intensity but also a high cost. Based on this, a further improvement is that a vertically arranged fixed plate is installed on the inner side of the lifting frame; the rack is installed on the fixed plate. With this setting, only one side of the fixed plate needs to be milled, thus reducing the milling area and lowering the labor intensity and cost.

[0012] Furthermore, an air inlet joint is provided in the air chamber; the air inlet joint is arranged at the lower end of the air chamber. With this setting, it is convenient to disassemble and assemble the air inlet joint without climbing heights.

[0013] To improve the jet intensity, a further design is that the end of the air chamber is semi-circular, and its arched part is close to the rack; the jet holes are arranged at the center position of the arched part of the air chamber. With this setting, the inner wall of the arched part of the air chamber guides the airflow. When the high-pressure air is ejected, a directional airflow will be formed, thus making the intensity of the airflow higher.

[0014] To improve the cleaning efficiency of the rack, a further improvement is that the axial direction of the jet holes is consistent with the inclination direction of the tooth grooves on the rack.

[0015] Since the air chamber is long and narrow, it is difficult to control the installation position accuracy. Based on this, a further improvement is that one side of the air chamber abuts against the fixed plate, and on the other side, multiple connecting plates are led out. The connecting plates are fixedly connected to the lifting frame through fasteners.

[0016] Since the flexibility of the air chamber is relatively large and it is easy to arch outwards, based on this, a further improvement is that the teeth on the rack protrude outwards from the fixed plate, so that the air chamber is limited between the lifting frame and the rack.

[0017] The beneficial effects of the present utility model are as follows: 1. The present utility model uses a gear-rack drive to lift the fork. The structure of the rack is simple, and only the tooth grooves of the rack need to be cleaned, thus reducing the maintenance difficulty; 2. When cleaning the tooth grooves of the rack, only high-pressure air needs to be filled into the air chamber. When the high-pressure air is ejected from the jet holes, it can clean the tooth grooves of the rack, thus avoiding the operation of climbing heights; 3. When lubricating the rack, only the lubricating oil needs to be applied to the gear. When the gear rises, the lubricating oil will be automatically coated on the rack, also avoiding the operation of climbing heights; 4. Compared with the chain and sprocket structure, the gear-rack drive method has better transmission efficiency and lower failure rate, improving the reliability of the fork lifting drive system of the stacker.

[0024] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0025] As Figure 1 and Figure 3 shown, the present utility model discloses a stacker that does not require climbing for maintenance, including a lifting frame 1 and a forklift fork. A rack 3 is vertically and symmetrically arranged on the lifting frame 1; gears driven by a reduction motor are arranged at both ends of the forklift fork and are engaged with the rack 3; when the reduction motor is started, the forklift fork can be driven to lift and lower.

[0026] To improve the lifting stability of the forklift fork, it is necessary to mill the inner side of the lifting frame 1 to improve the installation accuracy of the rack 3. However, this not only has a high labor intensity but also a high cost. Therefore, the following design is made: A vertically arranged fixing plate 6 is installed on the inner side of the lifting frame 1; the rack 3 is installed on the fixing plate 6. With this arrangement, only one side of the fixing plate 6 needs to be milled, thereby reducing the milling area and lowering the labor intensity and cost.

[0027] As Figure 2 shown, a hollow air chamber 4 is also installed on the lifting frame 1, and a plurality of air jet holes 5 facing the tooth grooves of the rack 3 are opened on the air chamber 4. The end of the air chamber 4 is semi-circular, and its arched part is close to the rack 3; the air jet holes 5 are arranged at the center position of the arched part of the air chamber 4. With this arrangement, the inner wall of the arched part of the air chamber 4 plays a guiding role for the air flow. When high-pressure air is ejected, a directional air flow will be formed, thereby making the intensity of the air flow higher.

[0028] Among them, the axial direction of the air jet holes 5 can be set to be consistent with the inclination direction of the tooth grooves on the rack 3, so as to improve the utilization rate of high-pressure air and thus improve the cleaning efficiency.

[0029] The air chamber 4 is provided with an air inlet joint 8; as Figure 4As shown in the figure, the air inlet joint 8 is arranged at the lower end of the air chamber 4. With this arrangement, it is convenient to disassemble and assemble the air inlet joint 8 without climbing to a height.

[0030] Since the air chamber 4 is long and narrow, it is difficult to control the installation position accuracy. Therefore, the following design is made: One side of the air chamber 4 abuts against the fixed plate 6, and multiple connecting plates 7 are led out from the other side. Through holes are provided at the ends of the connecting plates 7, and bolts pass through the through holes and are fixedly connected to the lifting frame to realize the fixation of the air chamber 4. In this way, the fixed plate 6 also plays a role in limiting the installation of the air chamber 4.

[0031] Since the flexibility of the air chamber 4 is relatively large and it is easy to arch outwards, the following design is made: The teeth on the rack 3 protrude outwards from the fixed plate 6, so that the air chamber 4 is limited between the lifting frame 1 and the rack 3.

[0032] The rack 3 can preferably be an inclined rack 3, and the gear is a matching helical gear. With this arrangement, some impurities will freely fall along the tooth grooves of the rack 3, thereby reducing the amount of impurities in the tooth grooves of the rack 3 and making cleaning more convenient.

[0033] The beneficial effects of the present utility model are as follows: 1. The present utility model uses a gear-rack 3 drive to lift the forklift. The structure of the rack 3 is simple, and only the tooth grooves of the rack 3 need to be cleaned, thereby reducing the difficulty of maintenance; 2. When cleaning the tooth grooves of the rack 3, only need to fill high-pressure air into the air chamber 4. When the high-pressure air sprays out from the air injection holes 5, it can clean the tooth grooves of the rack 3, thus avoiding the operation of climbing to a height; 3. When lubricating the rack 3, only need to apply lubricating oil on the gear. When the gear rises, the lubricating oil will be automatically coated on the rack 3, also avoiding the operation of climbing to a height; 4. Compared with the chain and sprocket structure, the gear-rack 3 drive method has better transmission efficiency and lower failure rate, improving the reliability of the forklift lifting drive system of the stacker.

[0034] Based on the above ideal embodiments of the present utility model as inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
