Electric fork head assembly and three-way piling car

Abstract

The invention discloses an electric fork head assembly and a three-way piling car. The electric fork head assembly comprises an inner sliding frame assembly, a lateral moving sliding frame assembly, a bridge assembly and a pallet fork assembly, the inner sliding frame assembly is connected with a forklift portal frame in a lifting mode through idler wheels, and a sliding block is arranged on the inner sliding frame assembly. The lateral moving sliding frame assembly is connected with the inner sliding frame assembly in a lateral moving mode, and an electric cylinder drives the lateral moving sliding frame assembly to laterally move left and right along the inner sliding frame assembly. One end of the bridge assembly is movably connected with the lateral moving sliding frame assembly. The pallet fork assembly is rotatably arranged at the other end of the bridge assembly. According to the electric fork head assembly and the three-way piling car, by arranging the sliding block and a linear guide rail, when a bridge laterally moves to the maximum stroke along a lateral moving sliding frame under the action of a power device, the electric cylinder can drive the lateral moving sliding frame to laterally move along an inner sliding frame, then the lateral moving stroke of the bridge is additionally increased, a driver can select the proper lateral moving distance according to the sizes of different channels and the sizes of different cargoes, a forklift is matched with the corresponding stacking channel and goods, and the working condition adaptability of the forklift is improved.

Description

technical field [0001] The invention relates to the technical field of three-way stacking truck equipment, in particular to an electric fork assembly and a three-way stacking truck. Background technique [0002] The modern logistics industry is developing rapidly, and the urbanization process is developing rapidly, and popular cities are very expensive. This requires higher and higher storage capacity ratios, and the application of three-way stacker trucks has greatly improved the storage capacity ratio and reduced land input costs. Chinese Patent Publication No.: CN110615384A discloses a forklift head device and its three-way stacking forklift. By setting a geared motor, the fork is driven to move laterally and rotate, with low noise, low energy consumption and high transmission efficiency; at the same time, All-electric drive without hydraulic oil and other media that pollute the environment, no pollution, high cleanliness. However, the above-mentioned stacking forklift ...

AI Technical Summary

Problems solved by technology

[0003] 1. The bridge frame moves left and right on the horizontal frame, causing the sideways movement distance of the entire fork assembly to be a fixed value. After the bridge frame slides left and right to the limit position, the fork reaches the limit position, and the corresponding stacking channel is a fixed value. The requirements for shelf stacking channels are relatively high. It is necessary to ensure that the dimensions of the existing channels must be consistent, and the size and specifications of the goods cannot be too different. The goods are completely regular and similar in size, which leads to the poor adaptability of the three-way forklift to the working conditions and cannot meet the complex working conditions;

[0004] 2. The aisles applicable to three-way forklifts are all narrow aisles, and the distance (safety distance) between the goods / shelves and the side-moving carriage of the forklift is small. Tilt left and right, causing one side of the side-moving carriage to approach the shelf, encroaching on the size of the safety distance, and a smaller safety distance will easily cause the forklift to collide with the goods / shelves, posing serious safety hazards;

[0005] 3. When a forklift stacks goods left and right, due to the inertia of the goods, there will be an impact, and the door frame will produce serious side-to-side shaking under the impact force. For example, when stacking bulk goods, if the shaking is severe, the goods will fall and the fork head structure will collide. Shelf and other risks
