Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a pneumatic layer-changing elevator, including an elevator frame, a mounting frame fixedly installed inside the elevator frame, a cylinder lifting mechanism fixedly installed inside the elevator frame via the mounting frame, a connecting frame fixedly installed on the cylinder lifting mechanism and located outside the elevator frame, a fixed frame fixedly installed on the connecting frame, two sets of conveyor frames fixedly installed on the top of the fixed frame, and multiple sets of conveyor rollers installed between the conveyor frames, wherein a drive motor for driving the conveyor rollers is fixedly installed on one of the conveyor frames.
[0005] The conveyor rollers are driven by a drive motor to achieve horizontal conveying of goods, while the goods are lifted by a cylinder lifting mechanism to change layers.
[0006] As a further preferred technical solution of this utility model, the cylinder lifting mechanism includes a mounting base plate fixedly mounted to the mounting bracket, a cylinder fixedly mounted on the top of the mounting base plate, a pushing end disposed on the top of the cylinder, and a protective housing fixedly mounted on the top of the pushing end and surrounding the outside of the cylinder.
[0007] The protective housing provides a certain level of protection for the cylinder, while the connecting frame is installed by pushing the cylinder from the top. As the protective housing is lifted, the protection of the cylinder is ensured during the lifting process.
[0008] As a further preferred technical solution of this utility model; a top frame is installed on the top of the lifting frame, and protective frames are fixedly installed on both sides of the cylinder lifting mechanism on the lifting frame, and lifting slide rails are fixedly installed on each of the protective frames.
[0009] The internal structure of the hoist frame is protected by a protective frame to ensure the hoist's effectiveness in protecting its internal components.
[0010] As a further preferred technical solution of this utility model, the connecting frame and the lifting slide rail are slidably installed.
[0011] The protective frame is lifted by a cylinder, and the lifting slide rail slides between the protective frame to achieve an auxiliary lifting effect, thereby ensuring the stability of the lifted structure during the pneumatic lifting process.
[0012] As a further preferred technical solution of this utility model; a protective side plate is fixedly installed on the top of the fixed frame on the front of a group of conveyor frames, an end plate is fixedly installed at one end between the conveyor frames, a transmission end is fixedly installed at the end of the conveyor roller, and the transmission end is connected to the inner side of the conveyor frame through a bearing, and the transmission ends are connected to each other through a transmission belt.
[0013] A set of conveyor rollers is driven by a drive motor, and the conveyor rollers are connected by a transmission belt, so that each set of conveyor rollers can rotate, thereby enabling the object to be transported horizontally after the lifting and layer changing is completed.
[0014] As a further preferred technical solution of this utility model, a limiting roller is installed between the conveyor frames at the edge end of the conveyor roller, and inclined auxiliary plates are fixedly installed on both sides of the limiting roller between the conveyor frames, with the top of the inclined auxiliary plate at the same height as the top surface of the limiting roller.
[0015] During the lifting process, the drive motor does not start, so the goods carried on the conveyor rollers are in a stable state without power transmission. After the lifting and layer change is completed, the drive motor drives the conveyor rollers to rotate, so that the goods on the conveyor rollers are transported. The inclined auxiliary plate, together with the driving force when the drive motor starts, assists in the transport of the goods.

[0017] With the help of the inclined auxiliary plate and the driving force of the drive motor, the goods are squeezed against the limiting rollers, causing the limiting rollers to move downwards as a whole, thus achieving the normal conveying effect of the goods. During the lifting process, the limiting rollers, being higher than the conveying rollers, provide a certain degree of protection for the goods, preventing them from shifting and falling off due to the sliding properties or smooth surfaces of the conveying rollers themselves. Beneficial effects
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] With the help of the inclined auxiliary plate and the driving force of the drive motor, the goods are squeezed against the limiting rollers, causing the limiting rollers to move downwards as a whole, thus achieving the normal conveying effect of the goods. During the lifting process, the limiting rollers, being higher than the conveying rollers, provide a certain degree of protection for the goods, preventing them from shifting and falling off due to the sliding properties or smooth surfaces of the conveying rollers themselves.
[0020] During the lifting process, the drive motor is not running, so the goods carried on the conveyor rollers are in a stable, unpowered state. After the lifting and layer change is completed, the drive motor rotates the conveyor rollers, transporting the goods. The inclined auxiliary plate, combined with the driving force of the drive motor at startup, assists in transporting the goods, keeping them stable during the lifting process.

[0026] This specific embodiment is a pneumatic layer-changing elevator.
[0027] The aforementioned utility model has a compact and simple structure and a lifting effect. However, if the goods are large or have an uneven shape during the lifting process, they are very likely to be shaken and fall, affecting the normal use of the elevator.
[0028] Its structural diagram is as follows Figures 1-4 As shown. A pneumatic floor-changing elevator includes an elevator frame 1, a mounting frame 14 fixedly installed inside the elevator frame 1, and a cylinder lifting mechanism 2 fixedly installed inside the elevator frame 1 via the mounting frame 14. The cylinder lifting mechanism 2 includes a mounting base plate 25 fixedly installed to the mounting frame 14, a cylinder 23 fixedly installed on the top of the mounting base plate 25, a pushing end 24 disposed on the top of the cylinder 23, and a protective housing 22 fixedly installed on the top of the pushing end 24 and surrounding the outside of the cylinder 23. The protective housing 22 provides a certain degree of protection for the cylinder 23, and the structure connected by the connecting frame 21 is pushed by the pushing end 24 on the top of the cylinder 23. As the protective housing 22 is lifted, the protective effect on the cylinder 23 is ensured during the lifting process.
[0029] It also includes a connecting frame 21 fixedly installed on the cylinder lifting mechanism 2 outside the lifting frame 1. A top frame 11 is installed on the top of the lifting frame 1, and protective frames 12 are fixedly installed on both sides of the lifting frame 1 on the cylinder lifting mechanism 2. Lifting slide rails 13 are fixedly installed on each of the protective frames 12. The protective frames 12 protect the internal structure of the lifting frame 1, ensuring the protective effect of the lifting machine on the internal components. The connecting frame 21 and the lifting slide rails 13 are slidably installed together. The cylinder 23 lifts the protective frame 12, and the sliding between the lifting slide rails 13 and the protective frame 12 achieves an auxiliary lifting effect, thereby ensuring the stability of the lifted structure during the pneumatic lifting process. It also includes a fixing frame 4 fixedly installed on the connecting frame 21. A protective side plate 41 is fixedly installed on the top of the fixing frame 4 on the front of a set of conveyor frames 42, and an end plate 45 is fixedly installed at one end between the conveyor frames 42. A transmission end 431 is fixedly installed at the end of the conveyor roller 43, and the transmission end 431 is connected to the inner side of the conveyor frame 42 by a bearing. The transmission ends 431 are connected by a transmission belt 432. A set of conveyor rollers 43 are driven by a drive motor 3, and the conveyor rollers 43 are connected by the transmission belt 432, ensuring that each set of conveyor rollers 43 rotates, thus allowing the object to be horizontally conveyed after the lifting and layer-changing process. The system also includes two sets of conveyor frames 42 fixedly mounted on the top of the fixed frame 4, and multiple sets of conveyor rollers 43 installed between the conveyor frames 42. A drive motor 3 for driving the conveyor rollers 43 is fixedly mounted on one set of conveyor frames 42. Limiting rollers 46 are installed between the conveyor frames 42 at the edge ends of the conveyor rollers 43. Inclined auxiliary plates 44 are fixedly installed on both sides of the limiting rollers 46 between the conveyor frames 42. The top of the inclined auxiliary plates 44 is at the same height as the top surface of the limiting rollers 46. During the lifting process, the drive motor 3 is not started, so the goods carried on the conveyor rollers 43 are in a stable, unpowered state. After the lifting and layer changing is completed, the drive motor 3 drives the conveyor roller 43 to rotate, thus conveying the goods on the conveyor roller 43. The inclined auxiliary plate 44, in conjunction with the driving force of the drive motor 3 when it starts, assists in the conveying of the goods. Both ends of the limiting roller 46 are fixedly installed to the docking plate 461 and the conveyor frame 42 respectively via bearings. A slider 462 is fixedly installed on the back of the docking plate 461, and mounting ends 463 are fixedly installed on both sides of the slider 462. A pad 422 is fixedly installed on the inner side of a set of conveyor frames 42 at the position of the docking plate 461. Two sets of positioning rods 421 are fixedly installed on the conveyor frame 42 at the top of the pad 422, and an auxiliary slide rail 423 is fixedly installed on the pad 422. The slider 462 and the auxiliary slide rail 423 are slidably installed together. The mounting ends 463 and the positioning rods 421 are connected by a connecting spring 464. With the tilting auxiliary plate 44 in place and the driving force of the drive motor 3, the goods squeeze the limiting roller 46, causing the limiting roller 46 to move downward as a whole, thereby achieving the normal conveying effect of the goods.During the lifting process, the setting of the limiting roller 46 above the conveying roller 43 provides a certain degree of protection for the goods. This prevents the goods from moving and falling off due to the sliding properties or smooth surface of the conveying roller 43 itself.
[0030] In actual use, the other end of the limiting roller 46 is connected to the conveying roller 43. Goods requiring layering are compressed by the inclined auxiliary plate 44 and the driving force of the drive motor 3, causing the limiting roller 46 to move downwards, thus achieving normal conveying of the goods. After moving to the lifting area, the protective box 22 is lifted by the push end 24 at the top of the cylinder 23. The cylinder 23 lifts the protective frame 12, and the sliding between the lifting slide rail 13 and the protective frame 12 provides auxiliary lifting, ensuring the stability of the lifted structure during pneumatic lifting. The lifting process protects the cylinder 23, and the setting of the limiting roller 46 above the conveying roller 43 provides a certain degree of protection for the goods. This prevents the goods from moving or falling off due to the sliding nature or smooth surface of the conveying roller 43.
[0031] All technical features in this embodiment can be freely combined according to actual needs.
[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
