Double-arm large-stroke bidirectional fork device

Abstract

The invention discloses a double-arm large-stroke bidirectional fork device. The double-arm large-stroke bidirectional fork device comprises a left fork body unit and a right fork body unit. The double-arm large-stroke bidirectional fork device is characterized in that each fork body unit comprises an upper fork body unit, a middle fork body unit and a lower fork body unit; the left fork body unit and the right fork body unit are synchronously driven through a drive unit; the drive unit comprises a motor, a transmission belt, a belt wheel, a drive shaft, a left drive gear and a right drive gear; an output shaft of the motor drives the belt wheel through the transmission belt; the belt wheel is arranged on the drive shaft in a sleeving manner; the left drive gear and the right drive gear are arranged on the drive shaft separately; the left drive gear and the right drive gear are in engagement connection with the transmission gear separately; the transmission gear is engaged with a gear group in the lower fork body unit; and a rack in the middle fork body unit is driven to move by the gear group. According to the double-arm large-stroke bidirectional fork device disclosed by the invention, the drive unit drives the gear group by virtue of the transmission gear, the middle fork body and the upper fork body are driven to synchronously move, and a rotation direction of the gears is changed to control a movement direction of the fork bodies, so that bidirectionally free cargo carrying is realized.

Description

technical field [0001] The invention relates to a handling device for conveying and stacking objects, in particular to a double-arm large-stroke bidirectional fork device. Background technique [0002] In the production process of modern enterprises, it is necessary to carry and stack a large number of goods, especially the handling and stacking of three-dimensional high-bay warehouses. It is necessary to adopt a mechanical device that can move in three-dimensional space and repeatedly move in a certain order to complete the handling and stacking of cargo units. This device is commonly referred to as a stacker. The most important functional part of the stacker is the fork. The grabbing, conveying, placing and other actions of the cargo unit are completed by the fork. [0003] Due to the limited structure of the existing fork device, in the process of cargo handling, ① its handling capacity is limited, and it cannot realize long-distance handling and stacking of goods, and...

Problems solved by technology

[0003] Due to the limited structure of the existing fork device, in the process of cargo handling, ① its handling capacity is limited, and it cannot realize long-distance handling and stacking of goods, and can only carry out one-way cargo handling. The handling range is limited, and high-load cargo handling is not possible

In particular, due to the imperfection of the fork drive or the structure, the movement of the fork is not continuous enough during the handling process, resulting in the inability to carry and stack the goods smoothly, the handling efficiency is low, and even the goods being transported may fall. On the one hand, there are Potential safety hazard, on the other hand, it will cause damage to the goods
