Special pallet fork for delivery test of whole forklift

Abstract

The invention discloses a special pallet fork for a delivery test of a whole forklift in the field of forklift pallet forks. The special pallet fork comprises a fork body, and an upper hook is fixedly connected to the upper portion of the rear surfaces of the fork body; and limiting blocks and guide sleeves which are arranged up and down are fixedly connected to the left side and the right side of the fork body, spring seats are arranged between the limiting blocks and the guide sleeves, springs are arranged between the spring seats and the guide sleeves, and the bottoms of the left guide sleeve and the right guide sleeve are jointly provided with a lower hook. The limiting blocks, the spring seats, the spring, the guide sleeves and the lower hook are sequentially through up and down through guide shafts, a third step used for limiting is arranged at the bottom end of each guide shaft, the upper ends of the guide shafts are limited above the limiting blocks through first fixing pieces, and second fixing pieces are fixedly connected to the portions, between the spring seats and the limiting blocks, of the guide shafts. The operation time for taking and placing the special pallet fork can be shortened, the delivery time is shortened to a certain extent, the labor intensity of operators is reduced, the test run labor cost is reduced, and in addition, the special pallet fork has the advantages of being reasonable in stress structure, long in service life, convenient to maintain and high in safety.

Description

technical field [0001] The invention relates to the field of forklift forks, in particular to a special fork used for the delivery test of a complete forklift. Background technique [0002] As a common lifting and transportation equipment in construction machinery, forklifts have been widely used in factories, docks, ports and other industries. The factory test of the whole forklift is the last link in the quality control of the product, and its importance is self-evident. In order to effectively carry out the factory test of the whole forklift, during the whole test process, the frequency of picking and placing the forks of the forklift is extremely high. Domestic manufacturers usually use standard forks to carry out tests, such as Figure 1-2 As shown, the standard upper hook 21 of the standard fork 2, the standard lower hook 23 and the fork body 22 are welded structures. Every time the fork is taken and placed, it is necessary to align the two forks with the installation...

AI Technical Summary

Problems solved by technology

[0004] 1. Every time the standard fork is picked and placed, the operator needs to get off the vehicle and operate continuously for a long time, which increases the labor intensity of the tester;

[0005] 2. Due to the cumbersome steps of picking and placing the standard fork, the efficiency of the test run operation is affected and the product delivery period is extended;

[0006] 3. Due to the low operating efficiency, under the condition of a certain output, more test personnel are required, resulting in higher labor costs;

In this way, when the vehicle leans forward, goes downhill, or brakes, the test block is easy to leave the fork frame together with the standard fork, and the position of the center of mass of the vehicle moves forward, which easily causes the vehicle to turn forward; the standard upper hook of the standard fork and the fork The stress at the welding part of the body increases sharply, and the weld seam is easy to tear, causing the test block to fall off and causing a safety accident

When the test block returns to its position, it will cause a large impact on the fork frame and the whole machine, which may easily cause damage to the fork frame of the vehicle under test
