Description

Field of invention

The invention generally relates to loading and unloading devices and transport devices for containers, more particularly, to a container transport vehicle for transporting across containers.

Background of invention

Now, the containers are transported from the front side of dock to the stack field by trucks mainly. Since in the whole operation, for example, in the unloading ship operation, the trucks position must be aligned when the containers are unloaded from ship by the shore bridge, moreover, with the higher lifting height and the larger lifting speed of the shore bridge, the difficulty is increased for alignment of the containers and the trucks. In order to align the position accurately, the longer time must be taken for the trucks and the shore bridge so that the operation efficiency is affected adversely.
Also, in the loading ship operation, it has the same problems of the alignment and time. The further increment of the operation efficiency is limited by these problems, therefore there is an urgent demand for developing a transport device which can transport containers across them easily, nimbly and rapidly, and can load and unload the containers automatically.

Summary of invention

It is an object of the invention to provide a container transport vehicle for transporting across container to resolve the following problems: the difficulty of the position alignment, the long time and the large amount of work, and the low operation efficiency. The container transport vehicle also increases the flexibility of transportation.
According to one aspect of the invention, a container transport vehicle for transporting across containers is provided, said container transport vehicle including: a large carrier frame; a diesel set being used as a power supply; a wheel support frame incorporating with a large carrier redactor; a large carrier drive machinery; and wheels, hanging tools and swing-resisting and translation machineries for the hanging tool, wherein, the vehicle further includes, a lifting machinery and a steering machinery; said large carrier drive machinery comprises a large carrier drive motor mounted on the wheel support frame, the large carrier reductor and wheel side brakes, the large carrier drive motor is connected to the large carrier reductor, the wheel side brakes are driven by a hydraulic means and are mounted in hubs, the large drive machinery comprises four wheel support frames; said lifting machinery is mounted in the middle of the large carrier frame, and equipped with four cylinders being connected to the hanging tools; said steering machinery is equipped with a steering cylinder, a steering arm, steering linkages and a plane turning bearing, the plane turning bearing is mounted on the wheel support frame being connected to an upper structure body for steering the wheel; each wheel support frame is equipped with steering linkages, a steering arm is mounted between the ends of two steering linkages, one end of the steering cylinder is connected to the steering arm, and the other end of the steering cylinder is mounted the carrier frame; the swing-resisting and translation machineries for the hanging tool drives the reel on the reductor by a drive motor, and draws the hanging tool by the steel rope on the reel; the transport vehicle has four sets of swing-resisting and translation machineries for the hanging tool, being arranged in two invert trumpet shape so that the hanging tool is in tension state and is possible to translate; the lifting machinery has a fixed non-extending structure fitting both the 40 feet container operation and the 20 feet container operation.
The container transport vehicle for transporting across containers of the present invention is a new type of the loading/unloading and transport device for containers. The container transport vehicle uses a four wheel drive and can lift one container and transport it in horizontal, the container transport vehicle also can prevent the container from swing. The container transport vehicle can be used to replace the container trucks. The purpose of the invention is to transport containers rapidly and reach the selected position, performing the horizontal transportation of the containers between the front side of dock and the stack field. The container transport vehicle also takes and unloads containers itself, that is, the containers on dock can be lifted or unloaded to the ground by the container transport vehicle.
The most advantages of the container transport vehicle for transporting across containers of the present invention are the flexibility, the rapid horizontal transportation, the fast alignment of position. And the container transport vehicle can lift and unload the containers by itself. The shore bridge only need to unload the container to the front side of dock, it is unnecessary for the bridge to align the container trucks accurately, the container transport vehicle can take containers by itself and transport them to stack fields rapidly, when it reaches the stack field position, it is unnecessary to align the stack field crane and only need to unload the containers to the ground. According to the present invention, the operation efficiency of the shore bridge is increased significantly.

Detailed description of preferred embodiment

With reference to figure 1 and 2, a container transport vehicle according to the invention is equipped with a large carrier frame 1, a diesel set 2 being used as a power supply, a wheel support frame 3, a large carrier drive machinery 4, a lifting machinery 5,a steering machinery, wheels 6, and the swing-resisting machinery and the hanging tool 9.
With reference to figure 3, the large carrier drive machinery 4 is composed of a large carrier drive motor 41 mounted on the wheel support frame 3, a large carrier reductor 42 and a wheel side brake 43, the electric drive is used for the large carrier drive. The large carrier drive motor 41 is connected to the high speed shaft of the large carrier reductor 42 directly to drive the large carrier reductor 42. The wheel support frame and the low speed shaft of the large carrier reductor 42 are connected to the shaft of the wheel 6 to turn the wheel 6. The wheel side brake 43 is driven by the hydraulic means and mounted in the hub 61. The whole large carrier drive machinery 4 is composed of four wheel support frames 3, each wheel support frame 3 is equipped with the large carrier drive motor 41, the large carrier reductor 42 and the wheel side brake 43.
The lifting machinery 5 is arranged in the middle of the large carrier frame 1, the lifting machinery 5 is equipped with four cylinders being connected to the hanging tool 9, the lifting of the hanging tools 9 and the unloading of the containers 10 are carried out by the extending and contracting of the cylinder 5.
With reference to figure 4 and 5, the steering machinery is equipped with a steering cylinder 71, a steering arm 72, steering linkages 73 and a plane turning 74. The plane turning bearing 74 is mounted at the upper portion of the wheel support frame 3 and connected to the upper structure body so that the wheel 6 may be steered. Each wheel support frame 3 is equipped with steering linkage 73, the steering arm 72 is mounted between the ends of two steering linkages 73, one end of the steering cylinder 71 is connected to the steering arm, and the other end of the steering cylinder 72 is mounted on the large carrier frame.
The steering wheel controlling the direction of the container transport vehicle is mounted in the driver chamber, the wheels on the carrier frame are driven by the hydraulic system, the steering cylinders, the steering linkages to carry out the steering action and the braking action. When the container transport vehicle need be steered, a operator turns the steering wheel in the driver chamber, the hydraulic steering system may be controlled by the steering wheel, the steering cylinders are driven to extend or contract, then the steering arms are turned by the steering cylinders, the steering linkages are displaced by the steering arms, finally the carrier frames and the wheels are driven to carry out the steering action. The steering angle of the inner side wheel is different to that of the outer side wheel, their radius of the turning are also different. When an operator steps on the braking paddle in the driver chamber, the wheels may be prevented from running by the wheel brakes so that the container transport vehicle can be stopped.
