Description

Container Straddle Truck

technical field

The invention relates to container loading and unloading and transport equipment, in particular to a transport vehicle for transporting containers across boxes.

Background technique

At present, containers are transported from the front of the terminal to the storage yard, mainly by trucks. Because in the whole operation chain link, such as ship unloading operation mode, that is, the quay crane must find and align the position of the truck when lifting the container from the ship, and the current quay crane has a high lifting height and a high lifting speed. Truck alignment adds to the difficulty. For accurate alignment, both the truck and the quay crane will spend a lot of time, thus affecting the work efficiency.

Equally, when loading operation, also there is the same alignment time problem. These problems have restricted the further improvement of operating efficiency, so it is urgent to develop a transport device that can not only transport containers across boxes lightly, flexibly and quickly, but also make the containers self-picking and self-unloading.

Contents of the invention

The task of the present invention is to provide a new container straddle container transport vehicle, which solves the problems of finding the correct position, difficult alignment, time-consuming and labor-intensive work efficiency, and affecting the operation efficiency when the current container is transported. At the same time, the flexibility of transportation is increased.

Technical scheme of the present invention is as follows:

A container straddle truck, which includes a large vehicle frame, a diesel engine group as a power source, a wheel supporting vehicle frame combined with a large vehicle reduction box, a large vehicle driving mechanism, wheels, a spreader and a spreader anti- It also includes a hoisting mechanism and a steering mechanism; the cart drive mechanism is mainly composed of a cart drive motor installed on the wheel support frame, a cart reduction box and wheel brakes, and the cart drive motor and The reduction box of the cart is connected, and the wheel brake is driven by hydraulic pressure and installed in the wheel hub. The whole cart driving mechanism is composed of four wheel support frames; the lifting mechanism is placed in the middle of the cart frame, and the lifting mechanism is installed There are four oil cylinders connected with the spreader; the steering mechanism is equipped with a steering cylinder, a steering arm, a steering link and a plane slewing bearing, and the plane slewing bearing is installed on the wheel support frame connected to the upper structure to steer the wheels Each wheel support frame is equipped with a steering link, a steering arm is installed between the ends of the two steering links, one end of the steering cylinder is connected to the steering arm, and the other end of the steering cylinder is installed on the frame; The anti-sway translation mechanism of the spreader is mainly driven by the drive motor to drive the reel on the reduction box, and the spreader is pulled by the wire rope on the reel. The tensioned state can also be used as a spreader for translation; the lifting spreader is a fixed and non-telescopic structure suitable for both 40-inch container operations and 20-inch container operations.

The container straddle truck of the present invention is a new type of container loading and unloading and transportation equipment. It adopts a unique four-wheel drive, can lift a container for horizontal transportation, and has the function of preventing the container from shaking, replacing the container truck. The purpose of this equipment is to quickly transport containers. It can reach the selected location and realize the horizontal transportation of containers between the front of the wharf and the yard. down to the ground.

The biggest advantage of the container cross-box transport vehicle of the present invention is that it is flexible, fast in horizontal transportation, fast in alignment, and can lift and unload containers by itself. With accurate positioning of the container truck, the truck can grab the container by itself and quickly transport it to the storage yard. When it reaches the storage yard, it does not need to align with the storage yard crane, and it can unload the container to the storage yard by itself, which greatly improves the Greatly improved the operating efficiency of the shore loading and unloading bridge.

Detailed ways

Referring to Fig. 1 and Fig. 2, a kind of container straddle box handling vehicle of the present invention is equipped with large vehicle frame 1, diesel engine group 2 as power source, wheel support vehicle frame 3, large vehicle drive mechanism 4, lifting mechanism 5, Steering mechanism, wheel 6, anti-sway mechanism and spreader 9.

Referring to Fig. 3, the cart drive mechanism 4 is mainly composed of a cart drive motor 41, a cart reduction box 42 and a wheel brake 43 installed on the wheel support frame 3, and the cart drive adopts electric drive. The cart driving motor 41 is directly connected with the high-speed shaft of the cart reduction box 42 to drive the cart reduction box 42 . It is not only the support frame of the wheel but also the low-speed shaft of the cart reduction box 42 to be connected with the 6 axles of the wheel to make the wheel 6 rotate. The wheel brakes 43 are hydraulically driven and mounted in the wheel hub 61 . Whole cart drive mechanism 4 is made up of four wheel support vehicle frames 3, and each wheel support vehicle frame 3 is all equipped with cart drive motor 41, cart reduction box 42 and wheel edge brake 43.

The hoisting mechanism 5 is arranged in the middle of the large vehicle frame 1, and the hoisting mechanism 5 is equipped with four oil cylinders connected with the spreader 9, and the lifting of the spreader 9 and the action of unloading the container 10 are completed by the expansion and contraction of the oil cylinders.

Referring to FIGS. 4 and 5 , the steering mechanism is equipped with a steering cylinder 71 , a steering arm 72 , a steering connecting rod 73 and a plane slewing bearing 74 . The plane slewing bearing 74 is installed on the top of the wheel supporting vehicle frame 3, is connected with the upper structure, and the wheel 6 can be turned. Each wheel support vehicle frame 3 is respectively equipped with steering connecting rod 73, and steering arm 72 is installed in the middle of the ends of two steering connecting rods 73, and one end of steering oil cylinder 71 is connected with steering arm 72, and the other end of steering oil cylinder 71 is installed on on the cart frame.

A steering wheel for controlling the direction of the truck is installed in the driver's cab 8, and the wheels on the vehicle frame are driven to perform steering and braking actions through the hydraulic system, steering cylinders, and steering linkages. When the truck is going to turn, the operator turns the steering wheel in the driver's cab, the steering wheel can control the hydraulic steering system, push the steering cylinder to expand and contract, the steering cylinder then pushes the steering arm, and the steering arm pulls the steering connecting rod to push the frame and wheels. Steering action. The turning angle of the inner wheel is different from that of the outer wheel, and the turning radius is also different. When the operator steps on the brake pedal in the cab, the wheel brake can be used to prevent the wheel from rotating, so that the truck stops running.

Referring to Fig. 6, in order to ensure that the spreader does not shake during transportation and the success rate of the spreader for one time, the carrier is also equipped with a spreader anti-sway and spreader translation mechanism 11.

The anti-sway translation mechanism 11 of the hanger is mainly driven by the drive motor 12 to drive the reel 14 on the reduction box 13, and pull the hanger 9 by the wire rope 15 on the reel 14. Four sets of anti-sway translation mechanisms 11 are housed in total on this truck, and are arranged in an inverted figure of eight, so that the spreader 9 is in a tensioned state and can be used for spreader translation. Label 16 among Fig. 6 is shackle, and 17 is door frame saddle beam, and 18 is door frame inner side, and 19 is door frame outside.

The hoisting spreader is a fixed non-telescopic structure, which can be applied to both 40-inch and 20-inch containers.
