Abstract

The invention discloses a forklift type AGV trolley, which includes a fork, a connection frame installed at the end of the fork, a control system and a power supply installed in the connection frame, a driving assembly and a lifting assembly, and there are at least two forks. Each pallet fork includes a base fixedly connected with the connection frame and a top seat above the base, the driving assembly and the lifting assembly are installed on the base, and the top seat is fixedly installed on the lifting assembly. The driving components are partly installed in the fork and partly under the base. As a part of the car body carrier, the fork can greatly reduce the size of the trolley, reduce the processing materials of the trolley, reduce the cost of the trolley, and also greatly reduce the weight of the trolley itself. The energy consumption due to its own weight during the operation of the trolley saves battery power; the driving wheel is placed in the middle of the fork, which greatly reduces the turning radius of the trolley, improves the flexibility of the trolley walking, and makes the production efficiency more efficient.

Description

Forklift type AGV trolley

technical field

The invention belongs to the field of transportation equipment, in particular to a forklift type AGV trolley.

Background technique

With the continuous rapid development of my country's economy and under the guidance of the strategic goal of "Made in China 2025", the storage and transportation system of the logistics industry and the material turnover system in the industrial production process are constantly developing. In order to reduce the logistics finished products in the production process and improve the logistics Efficiency, AGV trolleys with automatic picking, outbound and warehousing have increasingly appeared in logistics systems and industrial production material turnover processes.

However, the existing AGV trolley has the following problems when performing the above operations:

1. In the logistics industry and industrial production process, more goods are placed on the pallet, and the goods are transported by moving the pallet, while the traditional AGV car needs to manually place the pallet on the car, which reduces the production efficiency , but also increased transportation costs;

2. The existing AGV forklift is essentially the same structure as the traditional forklift (just change the manual driving to the automatic navigation system control). This kind of forklift is generally large in size, relatively heavy, has a large turning radius, and is not flexible to use. At the same time, the cost High (2 times or more than the cost of the present invention), low cost performance for most industrial production processes in China.

The relevant description of the prior art is as follows:

There are two main directions of existing technology:

1. Transform the control system of the traditional forklift (as shown in Figure 1), so that it can have the automatic walking function of AGV, and complete the process of automatic loading, unloading and moving materials, but in terms of its structure, it is different from the traditional forklift No difference, high cost, large volume and heavy weight, the weight of the car body is more than 1 ton (transporting 1 ton of goods); the traditional forklift traveling wheel system adopts two directional wheels for each device under the fork, and one side of the car body is Or a rudder wheel with walking and steering functions is installed in the middle. Based on this structure, the turning radius of the car body is large (turning around the rear rudder wheel), and it is not flexible to use.

2. The other is to install a fork behind the traditional AGV trolley (as shown in Figure 2) or above (as shown in Figure 3). Although this structure can simplify the structure of the forklift AGV, there are still problems. The rear fork still causes the overall size of the trolley to be larger. At the same time, the driving wheel is under the car body, and the turning radius is large. In order to ensure the balance of the trolley after the cargo is lifted, the car body still needs a large weight to balance the cargo. The second is the upper fork It is impossible to fork lift the pallet placed on the ground, and the balance of the trolley is poor.

Contents of the invention

The object of the present invention is to provide a forklift type AGV trolley which reduces the self-weight of the trolley but improves the load capacity and has a small turning radius.

In order to achieve the above effects, the solution adopted in the present invention is: a forklift type AGV trolley, which includes a fork, a connection frame installed at the end of the fork, a control system and a power supply installed in the connection frame, and a drive assembly As well as a lifting assembly, there are at least two pallet forks, each of which includes a base fixedly connected to the connection frame and a top seat above the base, the drive assembly and the lifting assembly are installed on the base , the top seat is fixedly installed on the lifting assembly.

Another preferred method is: the driving assembly includes a driving wheel mechanism and a universal wheel mechanism, the driving wheel mechanism is installed on the front side of the middle part of the pallet fork, and the universal wheel mechanism is mounted on the rear end of the pallet fork part, the lifting assembly is installed on the base between the driving wheel mechanism and the universal wheel mechanism.

Another preferred mode is: the driving wheel mechanism includes a driving motor, a gearbox, and a driving wheel that is drivingly connected to the gearbox.

Another preferred manner is: the universal wheel mechanism includes a universal seat fixedly connected to the base, and a driven wheel rotatably connected to the universal seat.

Another preferred way is: the lifting assembly includes a lifting motor, a worm gear part, a lifting block that is connected to the worm gear part and can slide up and down and is connected to the base. The lifting block is fixedly connected.

Another preferred manner is: the top seat cover is arranged on the base.

Due to the application of the above-mentioned technical solutions, the present invention has the following advantages compared with the prior art: the driving assembly is partly arranged in the fork and partly under the base, and the fork is used as a part of the car body carrier, which can greatly reduce the size of the car and reduce the The trolley processes materials to reduce the cost of the trolley, and at the same time greatly reduces the weight of the trolley itself, reduces the energy consumption due to its own weight during the operation of the trolley, and saves battery power; the driving wheel is placed in the middle of the fork, which greatly reduces the turning radius of the trolley , which improves the flexibility of the trolley and makes the production efficiency more efficient; the driving wheel and the driven wheel are partially placed under the fork, and the pallet is placed on the fork, and the weight of the goods on the pallet is directly determined by the driving wheel and driven wheel of the fork. Loading, and the center of gravity of the goods basically coincides with the center of the trolley, without generating additional overturning moment (the moment caused by the misalignment of the center of gravity of the goods and the center of the trolley causes the trolley to tip over), and the trolley runs more smoothly and safely.
