Description

Technical Field

[0001] This invention relates to the field of lifting equipment technology, and more specifically to a lifting machine. Background Technology

[0002] In some scenarios, vertical material conveying may present some problems, such as the stability of the conveying method, which is prone to shaking or deviation during the conveying process. This is especially true when conveying material trays, which need to be lifted stably. Shaking or deviation may cause damage or falling of the material in the tray. In addition, there is the problem of insufficient equipment continuity, which cannot meet the conveying needs of large-scale production, resulting in low production efficiency.

[0003] Therefore, this application studies a hoist that can stably transport material trays while improving transport efficiency. Utility Model Content

[0004] In order to stably convey material trays while improving conveying efficiency, this application provides a hoist.

[0005] The hoist provided in this application adopts the following technical solution:

[0006] A hoist includes a feeding assembly, a lifting assembly, and a discharging assembly. The lifting assembly includes a first driving member, two sets of lifting chains, and a plurality of supporting members. The first driving member simultaneously drives the two sets of lifting chains to rotate. Each set of lifting chains includes at least two lifting chains. A plurality of supporting members are spaced apart in each set of lifting chains. The supporting members of the two sets of lifting chains are respectively arranged one-to-one. The feeding assembly feeds a material tray onto the supporting members, and the material tray is placed on the supporting members on both sides. When the lifting chains drive the supporting members to a corresponding height, the discharging assembly pushes the material tray out for discharge.

[0007] By adopting the above technical solution, the support members on both sides can stably place the material tray, and the same drive component enables multiple lifting chains to lift stably and synchronously, making the material tray more stable during the ascent and avoiding shaking. This effectively solves the problems of insufficient stability, easy shaking or deviation, and improves the accuracy and reliability of material conveying. Furthermore, multiple support members can convey multiple material trays simultaneously. While the upper material tray is lifted into place and pushed out, a new material tray can be loaded onto the empty support member below, which can improve the efficiency of loading and unloading, thereby improving the conveying efficiency.

[0008] Optionally, the support member includes a support plate and two adjacent limiting plates perpendicular to the support plate.

[0009] By adopting the above technical solution, the material tray can be better limited and supported, preventing lateral slippage of the material tray during the lifting process, and further enhancing the stability of the material on the support.

[0010] Optionally, the lifting assembly further includes a transmission rod and two rotating rods. The rotating rods are engaged with the two ends of the transmission rod, and the lifting chain is sleeved on the rotating rods. The first driving member drives the transmission rod to rotate, and the transmission rod drives the rotating rods to rotate, thereby driving the lifting chain to rotate in the vertical direction.

[0011] By adopting the above technical solution, the power transmission is effectively achieved and the chain rotation is stabilized, ensuring the smooth lifting of the material tray. Moreover, this transmission method has a compact structure and reliable operation, which is conducive to improving the performance and service life of the entire elevator.

[0012] Optionally, the feeding assembly includes a second driving member and an ejector plate, wherein the second driving member drives the ejector plate to eject the material tray.

[0013] By adopting the above technical solution, automatic unloading of materials after the material tray reaches the corresponding height can be achieved, thus improving unloading efficiency.

[0014] Optionally, the unloading assembly further includes a guide rail, a connecting plate, and a guide plate, wherein the connecting plate is used to connect the ejector plate and the guide plate, and the guide plate cooperates with the guide rail.

[0015] By adopting the above technical solution, it is ensured that the material tray can be smoothly pushed out along the predetermined trajectory during the feeding process, avoiding the deviation or jamming of the material tray during the pushing process, and further improving the reliability of feeding.

[0016] Optionally, the unloading assembly further includes a position sensor, which is used to sense when the material tray has risen to the correct position. When the material tray has risen to the correct position, the unloading assembly pushes the material tray out.

[0017] By adopting the above technical solution, automatic detection and unloading control of the material tray rising to the correct position are realized, which improves the automation and intelligence level of the elevator and avoids problems such as unloading the material tray before it reaches the correct position or unloading in a timely manner due to human error. At the same time, the material tray below can also be synchronously fed to the support, ensuring the continuity and stability of material conveying.

[0018] Optionally, the feeding assembly further includes a feeding sensor, which is used to sense when the material tray is pushed out of the support. After the material tray is pushed out of the support, the lifting assembly continues to lift and convey.

[0019] By adopting the above technical solution, real-time monitoring of the feeding process and automatic control of the lifting components are realized, ensuring that the lifting components can continue to work in a timely manner after the material tray is fed, thereby improving the working efficiency of the elevator and avoiding problems such as equipment downtime or material accumulation caused by untimely feeding.

[0020] Optionally, the feeding assembly includes a third driving component and a feeding chain. The feeding chain is arranged parallel to the support component. The third driving component drives the feeding chain to rotate, thereby driving the material tray into the support component.

[0021] By adopting the above technical solution, automatic feeding of material trays is realized, which improves feeding efficiency, reduces manual intervention, and ensures that the material trays can be accurately placed on the support, thus making the material tray transmission stable.

[0022] Optionally, the feeding assembly further includes a feeding sensor, which is used to sense whether the material tray is in place. When the material is in place, the third driving component stops driving.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] 1. The support components on both sides can stably place the material tray, and the same drive component enables multiple lifting chains to lift stably and synchronously, making the material tray more stable during the ascent and avoiding swaying. This effectively solves the problems of insufficient stability, easy swaying or deviation, and improves the accuracy and reliability of material conveying. Furthermore, multiple support components can convey multiple material trays simultaneously. While the upper material tray is lifted into place and pushed out, a new material tray can be loaded onto the empty support component below, which can improve the efficiency of loading and unloading, thereby improving the conveying efficiency.

[0025] 2. The support plate and limiting plate can better limit and support the material tray, preventing the material tray from sliding laterally during the lifting process, and further enhancing the stability of the material on the support component;

[0026] 3. It ensures that the material tray can be smoothly pushed out along the predetermined trajectory during the feeding process, avoiding deviation or jamming of the material tray during the pushing process, and further improving the reliability of feeding. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0035] This application discloses a hoist. (Refer to...) Figure 1 The elevator includes a feeding assembly 1, a lifting assembly 2, and a discharging assembly 3. The lifting assembly 2 includes a first drive component 21, two sets of lifting chains 22, and several support components 23. The first drive component 21 simultaneously drives the two sets of lifting chains 22 to rotate. The lifting chains 22 are located on both sides of the first drive component 21, with the side facing the first drive component 21 being in the upward direction. Each set of lifting chains 22 includes at least two lifting chains 22. In this embodiment, each set has two lifting chains 22. Each set of lifting chains 22 is provided with multiple support components 23 spaced apart. The support components 23 are connected to the two lifting chains 22 of the set near their ends. The support components 23 of the two sets of lifting chains 22 are respectively arranged in a one-to-one correspondence, that is, the position corresponds to the height, so as to stably support the material tray.

[0036] The feeding assembly 1 feeds the material tray onto the support member 23. The material tray is placed on the support member 23 of the lifting chains 22 on both sides, and the support member 23 on both sides supports the material tray, ensuring its stability. When the lifting chain 22 lifts the support member 23 to the corresponding height, the unloading assembly 3 pushes the material tray out. During the unloading process, the support member 23 below continues to be fed through the feeding assembly 1, thereby improving the efficiency of loading and unloading and thus increasing the conveying efficiency.

[0037] Reference Figure 2 In some embodiments, the support member 23 includes a support plate 231 and two adjacent limiting plates 232 perpendicular to the support plate 231. The limiting plates 232 can limit and block the position of the material tray, making it more stable during the upward movement.

[0038] In this embodiment, the support members 23 on the two sets of lifting chains 22 can be arranged symmetrically, that is, the limiting members on the side facing the first driving member 21 all face upwards, so that when supporting the material tray, the left and right sides of the material tray can be limited simultaneously. In other embodiments, the limiting plates 232 on the same side of the two sets of lifting chains 22 face the same direction, that is, the limiting plates 232 on the left or right sides of the lifting chains 22 face the same direction, that is, the limiting plates 232 on the side of the two sets of lifting chains 22 facing the first driving member 21 face opposite directions, specifically one facing upwards and one facing downwards, so that no matter how the two sets of lifting chains 22 rotate, the limiting plate 232 of one set of lifting chains 22 will always face upwards, thus allowing for more stable placement and transmission of the material tray.

[0039] In some embodiments, the lifting assembly 2 includes a transmission rod 24 and two rotating rods 25. The rotating rods 25 are engaged with the two ends of the transmission rod 24 by bevel teeth, changing the rotation direction of the rotating rods 25. The lifting chain 22 is sleeved on the rotating rods 25 through gear engagement. The first driving member 21 drives the transmission rod 24 to rotate, which in turn drives the rotating rods 25 to rotate, thereby causing the lifting chain 22 to rotate in the vertical direction. In this embodiment, the first driving member 21 is a motor, and the output end of the motor is engaged with a chain. The chain and the transmission rod 24 are engaged by gear engagement to realize power transmission.

[0040] Reference Figure 3 In some embodiments, the feeding assembly 3 includes a second driving member and an ejector plate 31. The second driving member can be a driving member such as a cylinder. The ejector plate 31 is a cuboid plate structure with its largest surface in contact with the material tray. The second driving member drives the ejector plate 31 to eject the material tray in a straight line, so that the material tray can be fed stably.

[0041] In some embodiments, the feeding assembly 3 further includes a guide rail 32, a connecting plate 33, and a guide plate 34. The connecting plate 33 is used to connect the ejector plate 31 and the guide plate 34. The guide plate 34 is vertically arranged on the connecting plate 33. The ejector plate 31 is parallel to the connecting plate 33 and is located on the front side of the connecting plate 33. The guide plate 34 cooperates with the guide rail 32. In this embodiment, the guide plate 34 is connected to a guide block. Through the cooperation of the guide block and the guide rail 32, the material tray can be fed more stably.

[0042] In this embodiment, three guide rails 32 are spaced apart and connected to the guide plate 34 near both sides and the middle. This further enhances the stability and reliability of the guide, ensuring that the ejector plate 31 maintains a good guiding effect at different positions. Even when the material tray is heavy or the feeding speed is fast, the feeding process can be guaranteed to proceed smoothly, effectively improving the applicability and working performance of the elevator.

[0043] In some embodiments, the feeding assembly 3 further includes a position sensor 35, which senses when the material tray has risen to the correct position. When the tray reaches the correct position, the feeding assembly 3 pushes the material tray out, enabling accurate feeding of the material tray.

[0044] In some embodiments, the feeding assembly 3 further includes a feeding sensor 36, which is used to sense the material tray ejection support 23. After the material tray is ejected from the support 23, the lifting assembly 2 continues to lift and convey. One feeding sensor 36 can be provided above the ejection position and on each of the left and right sides, so as to more accurately sense the ejection of the material tray.

[0045] Reference Figure 4 In some embodiments, the feeding assembly 1 includes a third drive component 11 and a feeding chain 12. The third drive component 11 drives the feeding chain 12 to rotate. The feeding chain 12 is arranged parallel to the support component 23. In this embodiment, the feeding chain 12 is arranged parallel to the support plate 231. The third drive component 11 is a motor. The output end of the motor meshes with the chain, and the chain meshes with the output rod 13. Both ends of the output rod 13 mesh with the feeding chain 12. The motor drives the output rod 13 to rotate, which in turn drives the feeding chain 12 to rotate horizontally, causing the material tray to enter the support component 23. This enables efficient and stable feeding of the material tray.

[0046] In some embodiments, the feeding assembly 1 further includes a feeding sensor 14, which is used to sense whether the material tray is in place. When the material is in place, the third drive component 11 stops driving. The feeding and unloading are performed simultaneously in cooperation with the position sensor 35. When the feeding and unloading are completed, the lifting assembly 2 lifts the material tray.

[0047] The implementation principle of the elevator in this application embodiment is as follows: the support members 23 on both sides can stably place the material tray, and the same driving member enables multiple lifting chains 22 to be lifted stably and synchronously, thereby making the material tray more stable during the rising process, avoiding shaking, effectively solving the problems of insufficient stability, easy shaking or deviation, and improving the accuracy and reliability of material conveying; and multiple material trays can be conveyed simultaneously through multiple support members 23. While the upper material tray is lifted into place and pushed out, the lower new material tray can be loaded onto the empty support member 23 below, which can improve the efficiency of loading and unloading, thereby improving the conveying efficiency.
