Abstract
Description
Technical Field
[0001] This utility model relates to the field of logistics conveying equipment technology, specifically to an ultra-low structure lifting and transferring machine. Background Technology
[0002] As a key piece of equipment in logistics automation, the lifting transfer machine is used to change the direction of goods transportation, sending goods from the forklift into or out of the main conveyor line, and achieving right-angle turns under limited space conditions, which has the advantage of saving space.
[0003] Existing lifting and transferring machines generally have a double-layer structure. The upper layer consists of a lifting support with a powered conveyor module (chain, belt, roller, etc.), while the lower layer is a pneumatic, electric, or hydraulic lifting mechanism. The two combine to complete the lifting and transferring actions. Due to this double-layer structure, the lifting and transferring machine has a relatively large overall height. Since the lifting and transferring machine is installed below the conveyor, there are requirements for the minimum height of the conveyor, which also limits the minimum conveying height of the material.
[0004] For increasingly larger modern logistics pallet units, especially in multi-layer conveyor lines, reducing the structural dimensions of the lifting transfer machine can lower the ground clearance of each conveyor layer, facilitating personnel docking and operation, and saving equipment materials. Therefore, it is necessary to improve the existing lifting transfer machine structure to reduce the structural height while meeting load and lifting stroke requirements. Utility Model Content
[0005] The purpose of this invention is to solve the problem that the large height of the existing lifting and transferring machine body limits the minimum conveying surface height of the conveyor.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An ultra-low structure lifting and transfer machine, characterized in that it includes a lifting assembly and a transfer assembly installed directly above the lifting assembly;
[0008] The lifting assembly includes a lifting frame, a pair of parallel swing arm assemblies rotatably mounted on the lifting frame, and a lifting drive motor placed on the lifting frame between the two swing arm assemblies for driving the swing arm assemblies. Eccentric blocks are installed at both ends of the swing arm assemblies, and deep groove ball bearings are installed on the shafts on the eccentric side of the eccentric blocks.
[0009] The transfer assembly includes a transfer frame, a set of transfer arms symmetrically installed on both sides of the transfer frame, a transfer drive assembly for driving the transfer arms to run, installed on the middle transfer frame located between the two transfer arms, and a lifting and pulling plate installed on the side wall of the transfer frame to surround the swing arm assembly with a deep groove ball bearing.
[0010] A further improvement is that sprockets are fixedly connected to both the output end of the lifting drive motor and the shaft of the swing arm assembly. A chain connects the sprockets on the output end of the lifting drive motor and the sprockets on the shaft of the swing arm assembly. The lifting drive motor drives the swing arm assembly to rotate by means of the chain and sprockets as the connecting working medium.
[0011] A further improvement is that the two ends of the swing arm assembly are rotatably mounted on the lifting frame via two vertical ball bearings.
[0012] A further improvement is that a set of lifting guide shafts are symmetrically installed on the upper surfaces of the two sides parallel to the swing arm assembly of the lifting frame; a set of lifting guide blocks corresponding to the lifting guide shafts are installed by screws in the middle position of the transfer frame located on the two outer sides of the transfer arm.
[0013] A further improvement is that the lifting guide block is slidably sleeved on the lifting guide shaft to achieve lifting guidance.
[0014] A further improvement is that the lifting frame has a hollow opening located below the eccentric block to avoid the rotational movement of the eccentric block.
[0015] A further improvement is that the lifting guide shaft is mounted on the lifting frame via a guide shaft support, and an end cover plate is installed at the end of the lifting guide shaft.
[0016] A further improvement is that connecting frames are installed at the four corners of the lifting frame, and exterior sealing plates are installed between the outer walls of adjacent connecting frames by screws; the connecting frames are directly connected to the side plates of the external conveyor.
[0017] A further improvement is that the transfer drive assembly includes a transfer drive motor and a transfer transmission shaft. The transfer drive motor drives the transfer transmission shaft through the cooperation of a sprocket and a chain as a connecting working medium. The transfer transmission shaft is connected to the transfer support arm.
[0018] A further improvement is that the four corners of the transfer frame are fitted with chrome-plated wear-resistant strips that contact the deep groove ball bearings to maintain contact during lifting.
[0019] Compared with existing technologies, the above technical solution has the following advantages:
[0020] It can reliably transport and lift workpieces, while simultaneously meeting height and load requirements. Furthermore, its overall structure is more compact, reducing structural height while still meeting load and lifting stroke requirements. The staggered positioning of the lifting drive motor and the transfer drive motor allows for overlapping motor dimensions. Direct connection of the connecting frame to the conveyor side plate reduces leg space. Opening holes in the lifting component's frame to accommodate the lifting swing arm further reduces the height of the lifting component. In summary, this significantly reduces the overall structural height of the lifting and transferring machine. Attached Figure Description

Detailed Implementation
[0027] See Figures 1-4 As shown, the technical solution adopted in this specific embodiment is: an ultra-low structure lifting and transfer machine, including a lifting component 1 and a transfer component 2 installed directly above the lifting component 1;
[0028] The lifting assembly 1 includes a lifting frame 11, a pair of parallel swing arm assemblies 12 rotatably mounted on the lifting frame 11, and a lifting drive motor 13 placed on the lifting frame 11 between the two swing arm assemblies 12 for driving the swing arm assemblies 12. Eccentric blocks 122 are installed at both ends of the swing arm assemblies 12, and deep groove ball bearings 123 are installed on the shaft on the eccentric side of the eccentric blocks 122.
[0029] The transfer assembly 2 includes a transfer frame 21, a set of transfer arms 22 symmetrically mounted on both sides of the transfer frame 21 by bolts, a transfer drive assembly for driving the transfer arms 22 to run, and a lifting and pulling plate 25 mounted on the side wall of the transfer frame 21 surrounding the deep groove ball bearing 123 on the swing arm assembly 12.
[0030] In this configuration, sprockets 15 are fixedly connected to both the output end of the lifting drive motor 13 and the shaft of the swing arm assembly 12. A chain 14 connects the sprockets 15 on the output end of the lifting drive motor 13 and the sprockets 15 on the shaft of the swing arm assembly 12. The lifting drive motor 13 drives the swing arm assembly 12 to rotate by using the chain 14 and the sprockets 15 as the connecting working medium.
[0031] The two ends of the swing arm assembly 12 are rotatably mounted on the lifting frame 1 via two vertical ball bearings 121.
[0032] Among them, a set of lifting guide shafts 16 are symmetrically installed on the upper surfaces of the two sides parallel to the lifting frame 11 and the swing arm assembly 12; a set of lifting guide blocks 26 corresponding to the lifting guide shafts 16 are installed by screws in the middle position of the transfer frame 21 located on the two outer sides of the transfer arm 22.
[0033] The lifting guide block 26 is slidably sleeved on the lifting guide shaft 16 to achieve lifting guidance.
[0034] The lifting frame 11 has a hollow opening 124 located below the eccentric block 122 to avoid the rotational movement of the eccentric block 122.
[0035] The lifting guide shaft 16 is mounted on the lifting frame 11 via a guide shaft support, and an end cover plate is installed at the end of the lifting guide shaft 16. The guide shaft support and end cover plate prevent the lifting guide shaft 16 from being pulled out during operation.
[0036] The lifting frame 11 has connecting frames 3 installed at its four corners, and exterior sealing plates 4 are installed between the outer walls of adjacent connecting frames 3 by screws. The connecting frames 3 are directly connected to the side plates of the external conveyor, which saves on the support leg structure and reduces the height dimension.
[0037] The transfer drive assembly includes a transfer drive motor 23 and a transfer transmission shaft 24. The transfer drive motor 23 drives the transfer transmission shaft 24 through the cooperation of a sprocket and a chain as a connecting working medium. The transfer transmission shaft 24 is connected to the transfer support arm 22.
[0038] The transfer frame 21 has chrome-plated wear-resistant strips installed at its four corners to maintain contact with the deep groove ball bearing 123 during lifting. The lifting pull-down plate 25 of the transfer assembly 2 surrounds the deep groove ball bearing 123 on the swing arm assembly 12. If a problem of high guiding resistance and jamming occurs during the lowering action of the lifting transfer machine, the transfer assembly 2 can be pulled down through the contact between the deep groove ball bearing 123 and the folded edge of the lifting pull-down plate 25.
[0039] The working principle of this utility model is as follows: The swing arm assembly of the lifting component is mounted on the lifting frame through two vertical ball bearings with seats. Eccentric blocks are installed at both ends of the swing arm assembly, and deep groove ball bearings are installed on the shafts on the eccentric side of the eccentric blocks. The lifting drive motor is placed in the middle of the two sets of parallel swing arm assemblies, and drives the swing arm assembly to rotate by means of a chain and sprocket as the connecting working medium. The lifting frame is hollowed out below the eccentric blocks to avoid the rotational movement of the eccentric blocks. The lifting guide shaft is mounted on the lifting component through a guide shaft support, and an end cover plate is added to the end of the lifting guide shaft to prevent the lifting guide shaft from being pulled out during operation.
[0040] The transfer arms of the transfer assembly are bolted to the transfer frame. Two sets of transfer arms are driven by a transfer drive shaft. The transfer drive motor is located between the two sets of transfer arms, and a sprocket and chain drive the transfer drive shaft. A lifting and lowering plate is installed on the transfer frame, surrounding the deep groove ball bearing on the swing arm assembly. Lifting guide blocks are screwed to the middle of the two outer sides of the transfer frame, corresponding to the lifting guide shaft of the lifting assembly. Lifting guidance is achieved through the cooperation of the lifting guide blocks and the lifting guide shaft. Chrome-plated wear-resistant strips are installed at the four corners of the transfer frame, contacting the deep groove ball bearing of the lifting assembly and maintaining contact during lifting. The lifting and lowering plate surrounds the deep groove ball bearing on the swing arm assembly. If high guiding resistance causes jamming during the lowering action of the lifting transfer machine, the contact between the deep groove ball bearing and the folded edge of the lifting and lowering plate can pull the transfer assembly down. The connecting frames are connected to the side plates of the conveyor, saving on outrigger structures and reducing the overall height.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions provided are merely illustrative of the principles of this utility model.
