Embodiment Construction

[0048] This embodiment is a kind of goods fork that can be telescopic left and right, including a transmission system, a set of lower forks 3 and two sets of upper forks 1 and middle forks 2 with the same structure.

[0049] The lower roller bearings 24 on both sides of the bottom of the two middle forks 2 are embedded in the fixed guide rails 12 on the lower fork 3 respectively, and can slide freely in the fixed guide rails 12 . The upper roller bearings 23 on both sides of the top of the two middle forks 2 are respectively inlaid in the movable guide rails 33 of the opposite-shaped grooves on the upper fork 1, and can slide freely in the movable guide rails 33. The two groups of middle forks 2 are respectively located in the middle of the two pairs of fixed guide rails 12 on the lower fork 3 . The transmission system includes a reduction motor 4 connected to the lower fork motor fixing plate 17, a driving coupling 5, a passive coupling 6, a main sprocket 7, a bearing with se...

Abstract

The invention discloses a telescopic fork. Lower roll bearings of two groups of middle forks slide freely in fixed guide rails; upper roll bearings of two middle forks are positioned in movable guide rails of upper forks; and the two groups of middle forks are positioned at the middle parts of the fixed guide rails on a lower fork respectively. Two main chain wheels of a transmission system are positioned at the two ends of a first step of a transmission shaft respectively; the central line of one main chain wheel overlaps with that of a group of end chain wheel sets on the lower fork; the central line of the other main chain wheel overlaps with that of the other group of end chain wheel sets on the lower fork; and two bearings with seats are arranged at the lower parts of two U-shaped plates of a motor retaining plate respectively. An end retaining plate and a retaining plate are provided with limiters respectively. Through the roll bearings and the rails, the entire telescopic fork is light, convenient and flexible to move; and the travel of the fork is controlled by the limiters, so that the fork has the characteristics of compact structure, high working efficiency, safety and practicability.

Description

technical field [0001] The invention relates to a cargo handling device, in particular to a retractable cargo fork. Background technique [0002] The stacker is the core equipment of the automated three-dimensional warehouse, and the fork is the most important device for the stacker to access goods. [0003] In the invention patent whose application number is 200810227140.7, a stacker fork mechanism is proposed. The mechanism includes a lower fork, a middle fork, an upper fork and a load-bearing mechanism. Since the load-bearing steel rails in the load-bearing mechanism can be accurately docked with the steel rails on the shelf, the fork mechanism can be used for stackers to access large-sized and heavy goods. However, since the mechanism must have special load-bearing rails and rails connected to the load-bearing rails need to be provided in the rack, it has the disadvantages of complex structure and high price. It is not economical and practical when accessing goods wit...
