The existing container type semi-trailer needs to load goods into a container in advance and then load the container onto a frame. For example, a novel container type semi-trailer shown in chinese patent application No. cn201610782027.x comprises a frame, a box body, a box pushing device, a box transporting device and a frame conveying device, wherein the box pushing device comprises a top box hydraulic rod, a front pushing device and a rear conveying device; the box conveying device comprises a front conveying device and a rear conveying device, and the front conveying device and the rear conveying device respectively comprise a main conveying frame, a rotating shaft, a rotating frame, a rotating hydraulic rod, a wheel connecting hydraulic rod, a wheel frame, a spring and box conveying wheels; the frame conveying device comprises a rotating disc, a connecting shaft, a supporting frame, a frame conveying motor, a first sliding rod, a second sliding rod, a connecting rod and a limiting plate.

In the actual transportation process, the goods in the container often have the condition of less required goods loading amount, under the condition, the container type semi-trailer and other container type semi-trailers in the prior art still need to unload the container from the frame to complete the goods loading, or the goods are lifted to the height same as that of the container by a lifter, and then the goods are manually carried into the container to be stacked in order, so that the efficiency is very low; when the loading amount is small, the cargo in the container is easy to scatter in the moving process of the container due to the large free moving space of the cargo, so that the cargo is damaged.

Disclosure of Invention

Technical problem to be solved

The invention provides a container type semi-trailer, aiming at solving the following problems in the prior art: (1) when the required cargo capacity is less, the container type semi-trailer in the prior art still needs to unload the container from the frame to complete cargo loading, the cargo is lifted to the height same as that of the container by the lifter, and then the cargo is manually carried to the inside of the container to be stacked in order, so that the efficiency is very low; (2) when the required loading amount is less, the cargo in the container is easy to scatter in the moving process of the container due to the large free moving space of the cargo, so that the cargo is damaged.

(II) technical scheme

In order to solve the technical problem, the invention provides a container type semi-trailer which comprises a trailer head and a frame, wherein a rectangular cargo compartment is fixedly arranged on the frame, and an opening is formed in the end face of the cargo compartment close to the trailer head. The cargo compartment is provided with a container which is matched with the inner surface of the cargo compartment. The outer sides of the left side wall and the right side wall of the cargo compartment are inwards sunken to form a first strip-shaped slide rail in the vertical direction. The sliding plate in the horizontal direction is in sliding fit with the first strip-shaped sliding rail. The cargo box is provided with a lifting mechanism for lifting and lowering the slide plate. The upper surface of the sliding plate is fixedly provided with a first cylinder parallel to the side wall of the cargo compartment, the end part of a first piston rod on the first cylinder is provided with a first connecting frame, one end of the first connecting frame is positioned in the container and is fixedly connected with a first push plate vertical to the bottom surface of the container, and the first connecting frame is parallel to the side wall of the container.

And a second strip-shaped sliding rail in the vertical direction is arranged on the end surfaces of the left side wall and the right side wall of the cargo compartment along the edge of the opening. And a second cylinder barrel in the vertical direction is in sliding fit with the second strip-shaped sliding rail, and a second piston rod on the second cylinder is vertically downward. And a second connecting frame in the vertical direction is arranged on the cylinder barrel of the second cylinder, and a lifting plate in the horizontal direction is fixedly arranged at the bottom of the second connecting frame. When loading goods, preceding first piston rod extension on the first cylinder of driving drives first push pedal and removes the one side of keeping away from the container to the lift plate, then places the goods on the lift plate, and the downward extension of second piston rod on the second cylinder of redriving, after the second piston rod contradicted ground, the cylinder of second cylinder drove second link and lift plate upward movement to the realization promotes the goods to different heights. The first cylinder, the first connecting frame and the first push plate are adjusted to corresponding heights through the lifting mechanism. Shorten through the first piston rod on the first cylinder of drive, realize that first push pedal is to container inside removal, first push pedal is to the inside removal in-process of container, promotes the goods on the lift plate and with the goods to the inside propelling movement of container.

As a preferable technical scheme of the invention, the lifting mechanism comprises a winch which is fixedly arranged at the top of the cargo compartment and corresponds to the position of the first strip-shaped slide rail, and a lifting ring which is positioned between the first cylinder and the side wall of the cargo compartment is fixedly arranged on the upper surface of the slide plate. One end of a steel wire rope is fixedly connected to the hanging ring, and the other end of the steel wire rope is fixedly connected to a winding drum of the winch. The steel wire rope is wound through the winch, the steel wire rope lifts the sliding plate upwards through the lifting ring, and then the height of the first cylinder, the first connecting frame and the first push plate is changed, so that the pushing device is suitable for pushing goods with different heights and different levels.

As a preferred technical scheme of the present invention, the first push plate and the lifting plate are provided with grid openings parallel to each other, so as to reduce the weight of the first push plate and the lifting plate, reduce the load of the first cylinder and the second cylinder, and improve the service life of the first cylinder and the second cylinder. The bottom of first push pedal articulates there is a gyro wheel, and the in-process of first push pedal promotion goods, gyro wheel and container bottom plate rolling friction have reduced the frictional force between first push pedal and the container bottom plate, have both improved work efficiency, have promoted the life of first push pedal again.

As a preferred technical solution of the present invention, a horizontal third cylinder and a horizontal fourth cylinder are fixedly installed on a side surface of the first push plate close to the inside of the container, an extension direction of a third piston rod on the third cylinder is parallel to the first push plate, and an extension direction of a fourth piston rod on the fourth cylinder is parallel to the first push plate.
