Description

Semitrailer with self-discharging function for box throwing transportation

Technical Field

The utility model relates to a semitrailer structure for getting rid of case transportation, in particular to semitrailer with self-discharging function, be used for getting rid of case transportation.

Background

The container is used as an international goods loading tool, is widely applied to the fields of railways, highways, sea transportation and the like, and is an international modular transportation mode. Existing containers are 40 feet, 20 feet, 45 feet in length; a high box and a low box are arranged; there are special containers such as open top type, back open type, etc.

The transportation amount and the mileage of Chinese coal and particle goods are large, most of the coal in the existing market is transported by a common barn grate type semi-trailer, an 8.6-meter backward-turning dump truck and a 9.6-meter common vehicle, one part of the coal is transported from a coal mine to a peripheral power plant, a coal chemical plant and the like, and the other part of the coal is transported from the coal mine to a railway container station and then is transported remotely by a railway. The railway transportation is carried out by a plurality of containers through road and railway combined transportation, and the problem of difficult terminal unloading exists. In contrast, in recent years, the "change and integration" in the industry has been called more and more, but the greatest pain points at present are: containers do not have a relatively suitable means of unloading at the terminal of the transport.

SUMMERY OF THE UTILITY MODEL

In order to solve the existing problems, a box-throwing transportation scheme of the self-discharging container capable of achieving convenient discharging at a transportation terminal is developed through market research and technical demonstration. Therefore, the utility model provides a framework type container transport semi-trailer for this reason, can be convenient realize the problem of container transportation terminal point discharge; the container transport vehicle is additionally provided with the lifting system, and the cargo is self-unloaded under the condition that the container is not moved by utilizing hydraulic pressure, so that the problems of difficult unloading, unsafe situation and the like are solved, and the requirement of 'scattered change collection' is met. The utility model provides a pair of a semitrailer for getting rid of case transportation with self-discharging function has solved the defect and the problem that powder class goods container transportation such as current coal exists effectively, can realize the container self-discharging and get rid of case transportation, has expanded the function of container. The design of each part of the utility model is simple, convenient and reasonable.

Specifically, the utility model provides a semitrailer for getting rid of case transportation with self-discharging function, the semitrailer comprises container transport skeleton car and hydraulic pressure lifting system, hydraulic pressure lifting system arrange in inside the frame of container transport skeleton car for the movable bottom plate of the container of jack-up pulling transport to realize the whole self-discharging of goods.

The hydraulic lifting system comprises a hydraulic oil cylinder, an oil cylinder support, a control oil way and a control oil way connecting port. The hydraulic oil cylinder is arranged on the oil cylinder support and is used for jacking a corresponding jacking seat arranged on a movable bottom plate of the container; the top of the piston rod of the hydraulic oil cylinder can be aligned with the top seat (concave vertex) of the container pulled and transported at the upper part in the working space range. The oil cylinder support is arranged in the frame of the container transportation frame vehicle, and the position of the oil cylinder support corresponds to the top seat at the bottom of the container to be hauled. The control oil way is connected with a hydraulic system of the main vehicle through the control oil way connecting port to control the hydraulic oil cylinder to work, so that the movable bottom plate of the container pulled at the upper part can jack up the goods to be unloaded completely, and the whole container is unloaded safely under the condition that the container is not moved.

Preferably, the hydraulic oil cylinder and the oil cylinder support are arranged in pair, and the hydraulic lifting system further comprises a limiting spring; and the limiting spring for limiting is arranged between each pair of oil cylinders, so that the hydraulic oil cylinders are kept in a relatively fixed angle range.

Furthermore, according to the length of the container, one or more pairs of hydraulic oil cylinders and oil cylinder supports can be arranged along the length direction of the container transportation frame vehicle so as to jack up the movable bottom plate of the container simultaneously or step by step, thereby realizing the self-unloading of goods.

After unloading, the hydraulic control system of the main truck is operated to withdraw the piston rod of the hydraulic oil cylinder, and the movable bottom plate of the container at the upper part can be leveled. Because the hydraulic oil cylinder is not connected with the container pulled and transported at the upper part, the hydraulic oil cylinder can be used for container throwing transportation, and is very convenient and practical. The utility model discloses the example is 20 feet container skeleton transportation semitrailer, also can match the container transportation semitrailer (20 feet, 30 feet, 40 feet, 45 feet, 48 feet etc.) for various length specifications. The utility model aims at providing a can realize that the convenient container of unloading of transportation terminal gets rid of case self-discharging transportation scheme, this "a semitrailer for getting rid of case self-discharging" is this partly of getting rid of case transportation scheme. The container self-unloading and box-throwing transportation device is simple in structure, capable of achieving self-unloading and box-throwing transportation of the container, high in safety and convenient to process.

Detailed Description

The following describes the semi-trailer with self-unloading function for box-throwing transportation in further detail with reference to the accompanying drawings.

The utility model relates to a semitrailer for getting rid of case transportation with self-discharging function comprises hydraulic cylinder 1, hydro-cylinder support 2, spacing spring 3, control oil circuit 4, control oil circuit connector 5 and container transportation skeleton car 6. For the (served) hauling container, the cross section direction is provided with a left movable bottom plate and a right movable bottom plate (at least one group) which are overlapped and lapped mutually, and the two bottom plates can be upwards and outwards turned around the outer end point of the two bottom plates which is connected with the container frame, thereby realizing the lateral self-unloading of the goods.

Referring to fig. 1-2, the cylinder support 2 is mounted inside the frame of the container transportation frame vehicle 6 at a position corresponding to the top seat of the bottom of the container to be pulled. As shown in fig. 1, two hydraulic oil cylinders 1 are mounted (pivotally connected and supported) on two oil cylinder supports 2 respectively, and a limiting spring 3 for limiting is further connected between the two oil cylinders 1, so that the two hydraulic oil cylinders 1 are kept in a relatively fixed angular range, and the top of a piston rod of each hydraulic oil cylinder 1 can be aligned with a top seat of an upper pulled container in a working space range (see fig. 3).
