Description

A ground bull type forklift and method of using the same

technical field

The invention relates to the technical field of floor slab transport machinery, relates to a ground bull type forklift and a method of using the same, and particularly relates to a ground bull type forklift that can be used for the transportation of field-shaped slabs and a method of using the same.

Background technique

Forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. Forklifts are one of the most widely used mechanical equipment in the industrial field. Whether in warehouses, factories or construction sites, forklifts are required for a large number of cargo handling work. Due to the characteristics of their operations, current forklifts are mainly divided into two categories: counterbalanced forklifts and ground bull forklifts. However, these two types of forklifts have certain defects: 1. Although the counterbalance forklift has good applicability, it can be used to transport both Sichuan-shaped floor slabs and Tian-shaped floor slabs, but due to its structure Layout characteristics, its size is large, the turning radius is large, and it is difficult to use it flexibly in a relatively narrow space; Second, although the ground bull forklift has a small turning radius and is flexible and convenient, its fork arm is directly connected to the fork arm through the fork arm support wheel. If the ground is in contact, it can only transport the Sichuan-shaped floor plate. The bearing capacity of the Sichuan-shaped floor slab is far lower than that of the field-shaped floor slab, and the cost of the field-shaped floor slab is relatively high. Therefore, in the factory, the Sichuan-shaped floor slab and the Tian-shaped floor slab are often used together. To meet the needs of the Sichuan-shaped floor slab and the Tian-shaped floor slab, two types of forklifts are often required, which not only greatly increases the equipment cost, but also is inconvenient to use.

Therefore, it is of great practical significance to develop a forklift structure that can overcome the inherent defects of counterbalanced forklifts and ground bull forklifts.

SUMMARY OF THE INVENTION

Due to the above-mentioned defects in the prior art, the present invention provides a ground bull-type forklift suitable for the transportation of field-shaped floor decks and a method for using the same, so as to overcome the inherent defects of the counterbalanced forklift and ground bull-type forklift. The ground bull type forklift is not only flexible and convenient, but also applicable to the field-shaped floor plate. The application of the forklift of the present invention can not only greatly reduce the equipment purchase cost of the factory, but also has good convenience in use.

In order to achieve the above object, the present invention provides the following technical solutions:

A ground bull type forklift includes a forklift main body and a fork arm for carrying goods;

The bottom of the forklift main body is provided with at least three forklift main body support wheels that are not on the same straight line;

The fork arm is arranged on one side of the main body of the forklift, and the fork arm is provided with a fork arm supporting wheel group, the forklift main body is fixedly connected to the fork arm through a power mechanism, and the fork arm supporting wheel group is supported by the fork arm. Connected with the power mechanism, the distance between the fork arm and the ground and the distance between the fork arm support wheel set and the fork arm can be adjusted by controlling the power mechanism;

When the fork arm supporting wheel set is completely retracted into the fork arm, the fork arm supporting wheel set is out of contact with the ground, and a certain distance is left between the fork arm and the ground. The Diniu AGV forklift can be obtained by intelligently transforming the above-mentioned Diniu-type forklift. The forklift can reach the designated position according to the signal instructions and complete the transportation work, which can greatly improve the operation efficiency of the smart factory. Using the ground bull type forklift of the present invention can realize the unification of forklift specifications, which can not only facilitate forklift scheduling, but also reduce equipment procurement and maintenance costs.

The ground bull type forklift truck of the present invention has reasonable and exquisite structural design, and its main structure is basically the same as that of the ground bull type forklift truck in the prior art (such as the fork arm supporting wheel set, the power mechanism, namely the hydraulic cylinder, the fork arm and the fork arm supporting wheel connecting rod The connection relationship is the same), the main difference is that it can completely retract the fork arm support wheel set into the fork arm, and at the same time the fork arm is suspended in the no-load state, and the fork arm can be easily inserted into the gap of the field-shaped floor plate , It is suitable for the transportation of the field-shaped floor plate. After the fork arm goes out of the field-shaped floor plate, the fork arm is raised, and the supporting wheel set of the fork arm will also be lowered until the supporting wheel set of the fork arm is in contact with the ground, and the transportation can be carried out. The invention provides a new technical perspective for the improvement of the forklift, and found an ingenious and reasonable improvement idea in the blind area of the technician's thinking. Three forklift main support wheels have great application prospects.
