Description

Technical Field

[0001] This invention relates to the field of automated logistics warehousing, specifically to a fork synchronous horizontal sliding device. Background Technology

[0002] For densely stored light-load bins, multi-level shuttles have been widely used due to their advantages such as low cost, flexible configuration, and high loading and unloading efficiency. However, most currently used multi-level shuttles have fixed-width forks designed for fixed cargo or bin widths, which cannot adapt to cargo or bins of various widths. Some adjustable-width clamping forks use synchronous belts or ball screws to pull the middle part of the fork plate to adjust the fork spacing. This structure occupies a large amount of vehicle space, has poor fork stress distribution, and is inconvenient to maintain. Summary of the Invention

[0003] The purpose of this invention is to provide a fork synchronous horizontal sliding device, which allows the fork plates to be adjusted in spacing as needed, and the fork plates have good stress distribution and will not deform after long-term use.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A fork synchronous horizontal sliding device includes a fork plate, a first toothed shaft, a second toothed shaft, and a clamping drive assembly. The first and second toothed shafts are fixed in parallel. A first sliding element is mounted on the first toothed shaft, and a second sliding element is mounted on the second toothed shaft. One end of the fork plate is fixedly connected to the first sliding element, and the other end is fixedly connected to the second sliding element. A first clamping seat is provided on the first sliding element, and a second clamping seat is provided on the second sliding element. The clamping drive assembly includes a drive mechanism, a first driven gear, a second driven gear, and a transmission shaft. The drive mechanism and the first driven gear are located on the first clamping seat. The first driven gear meshes with the first toothed shaft and is driven to rotate by the drive mechanism. The second driven gear is located on the second clamping seat. The second driven gear meshes with the second toothed shaft and is coaxially connected to the first driven gear through the transmission shaft.

[0006] Both the first sliding element and the second sliding element are linear sliding film bearings.

[0007] The drive mechanism includes a motor and a drive gear. The first clamping seat is provided with a motor seat, and the motor is fixedly mounted on the motor seat. The drive gear is mounted on the output shaft of the motor. One end of the transmission shaft is rotatably mounted on the motor seat by bearing support. The first driven gear is fixedly connected to the corresponding side shaft end of the transmission shaft, and one end of the first driven gear meshes with the drive gear, while the other end meshes with the first toothed shaft.

[0008] The second clamping seat is provided with a bearing seat, and the corresponding side shaft end of the transmission shaft is rotatably mounted on the bearing seat by bearing support.

[0009] The advantages and positive effects of this invention are as follows:

[0010] 1. This invention allows the spacing of the fork plates to be adjusted as needed, and the fork plates are subjected to force at both ends during movement, resulting in good force distribution and preventing deformation of the fork plates after long-term use.

Detailed Implementation

[0019] The invention will now be described in further detail with reference to the accompanying drawings.

[0020] like Figures 1-6As shown, the present invention includes a fork plate 1, a first toothed shaft 201, a second toothed shaft 202, and a clamping drive assembly 6. The first toothed shaft 201 and the second toothed shaft 202 are fixedly mounted parallel to each other on the equipment frame. A first sliding element 301 is mounted on the first toothed shaft 201, and a second sliding element 302 is mounted on the second toothed shaft 202. One end of the fork plate 1 is fixedly connected to the first sliding element 301, and the other end is fixedly connected to the second sliding element 302. A first clamping seat 4 is provided on the first sliding element 301, and a second clamping seat 5 is provided on the second sliding element 302. The clamping drive assembly 6 includes a drive mechanism, a first driven gear 604, a second driven gear 607, and a transmission shaft 605. Wheel 604 is mounted on the first clamping seat 4, and the first driven gear 604 meshes with the first toothed shaft 201 and is driven to rotate by the driving mechanism. The second driven gear 607 is mounted on the second clamping seat 5, and the second driven gear 607 meshes with the second toothed shaft 202 and is coaxially connected to the first driven gear 604 through the transmission shaft 605 to achieve synchronous rotation. Since the first toothed shaft 201 and the second toothed shaft 202 are both fixed, the rotation of the first driven gear 604 and the second driven gear 607 drives the first sliding element 301 and the second sliding element 302 to move axially along the first toothed shaft 201 and the second toothed shaft 202 respectively, thereby causing the fork plate 1 to move to achieve the purpose of adjusting the spacing.

[0021] In this embodiment, both the first sliding element 301 and the second sliding element 302 are linear sliding film bearings, and both ends of the fork plate 1 are fixed to the corresponding linear sliding film bearings by screws. The linear sliding film bearings are known in the art and are commercially available products.

[0022] like Figures 2-4 As shown, in this embodiment, the driving mechanism includes a motor 601 and a drive gear 603. A motor mount 602 is provided on the first clamping seat 4, and the motor 601 is fixedly mounted on the motor mount 602. The drive gear 603 is fitted onto the output shaft of the motor 601. One end of the transmission shaft 605 is rotatably mounted on the motor mount 602 via a bearing. A first driven gear 604 is fixedly connected to the corresponding end of the transmission shaft 605. One end of the first driven gear 604 meshes with the drive gear 603, and the other end meshes with the first toothed shaft 201. When the mechanism is working, the motor 601 transmits torque through the drive gear 603 to drive the first driven gear 604 to rotate, and drives the second driven gear 607 on the other side to rotate through the transmission shaft 605.

[0023] like Figures 5-6As shown, in this embodiment, the second clamping seat 5 is provided with a bearing seat 606, and the corresponding side shaft end of the transmission shaft 605 is rotatably mounted on the bearing seat 606 by bearing support. The second driven gear 607 is fixedly connected to the corresponding side shaft end of the transmission shaft 605 and meshes with the second toothed shaft 202.

[0024] The working principle of this invention is as follows:

[0025] In operation, the first toothed shaft 201 and the second toothed shaft 202 are fixed to the equipment frame. The motor 601 drives the drive gear 603 to rotate, which in turn drives the first driven gear 604 to rotate. The first driven gear 604 drives the second driven gear 607 to rotate synchronously via the transmission shaft 605. Since the first driven gear 604 meshes with the first toothed shaft 201 and the second driven gear 607 meshes with the second toothed shaft 202, the rotation of the first driven gear 604 and the second driven gear 607 respectively drives the corresponding clamping seats and sliding elements to move along the toothed shafts on the corresponding sides, thereby causing the fork plates 1 on the corresponding sides to move. The movement of the fork plates 1 on both sides achieves the purpose of adjusting the spacing. In this invention, the fork plates 1 are subjected to force at both ends during movement, resulting in good force distribution and preventing deformation of the fork plates 1 even after long-term use.
