Description

Technical Field

[0001] This utility model belongs to the field of logistics and transportation technology, and in particular relates to a lifting and transfer mechanism that can improve the service life of the lifting mechanism. Background Technology

[0002] A lifting and transfer mechanism is a mechanism used to transfer and change the direction of workpieces between conveyor belts of different heights. It is commonly used in logistics transportation lines to save space and improve efficiency.

[0003] For example, utility model patent CN222180960U discloses an extremely low-profile, medium-load three-row chain transfer machine, including a mounting frame, a three-row chain transfer mechanism, a base frame, two sets of lifting components, and a drive component. This design uses the drive component to rotate two rotating rods, which in turn rotate four cams, which in turn rotate four rotating wheels. When the tips of the cams are above the rotating rods, the four rotating wheels lift four brackets, thereby moving the mounting frame upwards, and thus moving the three-row chain transfer mechanism and the goods on the three-row chain transfer machine upwards. This lifting method offers better stability compared to traditional cylinder lifting methods, and the transmission via sprockets and chains ensures that the four cams and four rotating wheels move synchronously.

[0004] In the aforementioned lifting and transferring mechanism, the driving mechanism is a motor. When lifting material pallets, the output end bears a large load due to the weight of the material. In some cases, the motor may even fail to maintain a stable lifting height due to the excessive weight of the material (the motor may reverse and descend under the pressure of the material). This situation will reduce the service life of the motor. Based on the above problems, the applicant has designed a solution that can improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a lifting and transfer mechanism that can improve the lifespan of the lifting mechanism, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lifting and transferring mechanism that can improve the service life of the lifting mechanism, comprising a transferring component and a lifting component for controlling the lifting and lowering of the transferring component, and a support component. The support component includes a support block and a drive component for controlling the support block to move in the horizontal direction. The transferring component is provided with an upper abutment part, and the lifting component is provided with a lower abutment part. When the lifting component controls the transferring component to rise, the drive component controls the support block to insert between the upper abutment part and the lower abutment part.

[0007] Preferably, the drive assembly includes a drive cylinder, and the support block is disposed at the output end of the drive cylinder.

[0008] Preferably, the driving assembly includes a driving cylinder, a telescopic sleeve, an elastic element, and an abutment plate. The telescopic sleeve is fixed to the support block. A slider is fixed to the piston rod of the driving cylinder. The slider slides inside the telescopic sleeve. The outer diameter of the slider is larger than the outer diameter of the piston rod. A limiting cover plate is provided on the telescopic sleeve to prevent the slider from sliding out of the telescopic sleeve. One end of the elastic element abuts against the abutment plate, and the other end abuts against the support block, so as to apply a force to the support block to make it move between the upper abutment part and the lower abutment part.

[0009] Preferably, it also includes a slide rail, on which the support block slides, and the slide rail forms a lower abutment portion.

[0010] Preferably, a rolling element is provided on the surface of the support block that contacts the upper abutment portion and / or the lower ground abutment portion.

[0011] Preferably, the edges of the support block that enter the upper abutment portion and / or the lower ground abutment portion are chamfered.

[0012] Preferably, a buffer is fitted on the piston rod, one end of which can abut against the slider and the other end of which can abut against the limiting cover plate.

[0013] The beneficial effects of this utility model are as follows: By setting up a support block, after the transfer mechanism rises, the drive component drives the support block to insert between the upper abutment part and the lower abutment part, forming a support function. When the motor in the lifting component rotates slightly, the support block supports the transfer component, reducing the pressure on the output end of the lifting component and thus effectively improving the life of the motor.

[0014] In this solution, a drive cylinder can be used to insert and withdraw the support block; alternatively, an elastic element can be used to insert the support block, while the drive cylinder is used to withdraw it. This arrangement effectively eliminates the time interval between the movement of the drive assembly and the lifting assembly, ensuring that the support block can be quickly and directly inserted under the action of the elastic element when the upper and lower abutment parts are open to accommodate the entry of the support block.

[0015] By setting up slide rails, the stability of the movement path of the support block is effectively guaranteed;

[0016] By installing rolling elements on the support block, the smoothness of the support block insertion and removal process can be ensured.

[0017] By creating chamfers on the support blocks, the smooth insertion of the support blocks can be ensured.

[0018] By incorporating a buffer, the noise generated by the collision between the slider and the limiting cover plate during the process of pulling out the support block can be reduced. Attached Figure Description

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0031] Example:

[0032] See Figure 1-4 , Figure 7A lifting and transfer mechanism that can improve the lifespan of the lifting mechanism includes a transfer component 1 and a lifting component 2 for controlling the lifting and lowering of the transfer component 1. In this embodiment, the transfer component 1 adopts a three-row chain structure as described in the background art solution, which controls the movement of the chain through a linear drive motor 101. The lifting component 2 includes a base frame 202 and a lifting drive motor 201. The lifting drive motor 201 drives two rotating shafts 203 to rotate through the chain. A cam structure 204 is provided at the end of the rotating shaft 203. The cam structure 204 abuts against the bottom surface of an abutting angle iron 102 fixed on the transfer component 1. The rotation of the cam structure 204 controls the up and down movement of the abutting angle iron 102. Two vertically arranged guide columns 205 are provided on the base frame 202. A guide block 103 that slides on the guide columns 205 is fixed on the transfer component 1. The above are all prior art contents and will not be elaborated further in this article.

[0033] Among them, see Figure 3-6 A support assembly 3 is provided on the base frame 202. The support assembly 3 includes a support block 302 and a drive assembly that controls the support block 302 to move in the horizontal direction. The transfer assembly 1 is provided with an upper abutment part, and the lifting assembly 2 is provided with a lower abutment part. When the lifting assembly 2 controls the transfer assembly 1 to rise, the drive assembly controls the support block 302 to insert between the upper abutment part and the lower abutment part.

[0034] The drive assembly includes a drive cylinder 301, and the support block 302 is disposed at the output end of the drive cylinder. In this embodiment, the upper contact part is the guide block 103, and the lower contact part can be the ground or the base frame 202, etc.

[0035] In another optimized embodiment, the driving assembly includes a driving cylinder 301, a telescopic sleeve 306, an elastic element 308, and an abutment plate 307. The telescopic sleeve 306 is fixed to the support block 302. A slider 310 is fixed to the piston rod of the driving cylinder 301. The slider 310 slides inside the telescopic sleeve 306. The outer diameter of the slider 310 is larger than the outer diameter of the piston rod. A limiting cover plate 309 is provided on the telescopic sleeve 306 to prevent the slider 310 from sliding out of the telescopic sleeve 306. One end of the elastic element 308 abuts against the abutment plate 307, and the other end abuts against the support block 302 to apply a force to the support block 302 to make it move between the upper abutment part and the lower abutment part. The elastic element 308 can be a spring. The base frame 202 is also provided with a slide rail. The support block 302 slides on the slide rail. The guide block 103 forms the upper abutment part, and the slide rail forms the lower abutment part.

[0036] In the above scheme, a rolling element 304 is provided on the surface of the support block 302 that contacts the upper abutment part and / or the lower ground abutment part. The rolling element 304 can be a ball. The position of the ball is fixed by opening a semi-circular groove on the support block 302 to accommodate the ball, and setting a connecting cover plate 305 on it to restrict the ball within the semi-circular groove. The connecting cover plate 305 needs to have a through hole to expose the ball.

[0037] The support block 302 has a chamfered edge on the edge where it enters the upper abutment part and / or the lower ground abutment part.

[0038] The piston rod is fitted with a buffer (not shown), one end of which can abut against the slider 310, and the other end of which can abut against the limiting cover plate 309. The buffer can be a spring, elastic gasket, etc.

[0039] Working principle and process:

[0040] When using the equipment of this solution, the lifting component 2 drives the transfer component 1 to rise. During this process, the piston rod of the drive cylinder 301 is in the extended state and is subjected to the action of the elastic element 308, so that the support block 302 is always subjected to the force of moving towards the upper abutment part and the lower abutment part. When the distance between the upper abutment part and the lower abutment part is sufficient, the support block 302 is inserted between the upper abutment part and the lower abutment part under the action of the elastic element 308, so as to support the transfer component when the lifting motor cannot guarantee the height stability of the transfer component 1. This effectively reduces the pressure at the output end of the lifting motor and improves the service life of the lifting motor. After the transfer is completed, the piston rod of the drive cylinder 301 retracts, and the upper slider 310 abuts against the limit cover plate 309 and drives the support block 302 to be pulled out between the upper abutment plate 307 and the lower abutment plate 307 along the guide rail 303.

Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
