Background

In recent years, the development of the car industry in China is rapid, the traffic volume of cars is increased year by year, and various freight transportation companies and logistics companies are used for adapting to the demands of the car transportation market and highlighting the advantages in strong market competition so as to obtain more market share and strive for low transportation cost and high transportation efficiency.

The domestic railway car transport vehicle is vigorously developed in the strong growth of car consumer markets, and due to the adoption of an all-steel closed rivet welding structure, other cargoes cannot be assembled, so that most of vehicles can only be returned by empty vehicles, and the vehicles can only be idle and occupy lines in off-season, so that the vehicle utilization rate is low, the use cost is increased, and the transport capacity of railway lines is greatly wasted. In recent years, the development of multi-type intermodal is greatly promoted in the country, and the multi-type intermodal mainly uses container transportation, and if the two types of intermodal can be complemented, the maximization of equipment benefit can be realized. Patent publication number CN 104802811A discloses a car-container sharing special transport vechicle, and this car turns over downwards through middle part activity chassis, only can be used to load 140 ft containers, and vehicle chassis length utilization ratio is 50% lower than the flatcar, and economic benefits is not high, and this car side wall is higher, and difficult observation when container loads, easily crashes side wall or container, difficult operation is unfavorable for the popularization and application of dual-purpose car.

The existing car of railway transport vechicle's vehicle structure restriction can't carry out high-efficient dual-purpose in the transportation, and the operation is inconvenient, and this problem needs to be solved urgently.

Disclosure of Invention

The invention aims to provide the dual-purpose concave bottom transport vehicle for the automobile and the container, aiming at solving the problems that the existing railway car transport vehicle cannot transport the container in full length under the chassis, the container is easy to collide, the operation is inconvenient, the transport capacity of the vehicle is low, the transport cost is high and the like. In order to achieve the above purpose, the present invention provides the following technical solutions:

A dual-purpose concave bottom transport vehicle for an automobile and a container comprises a lower underframe, a middle underframe lifting device and an end underframe lifting device; the middle part of the lower underframe is provided with a concave bottom, two ends of the lower underframe are provided with high bottoms, and the concave bottom is connected with the high bottoms through inclined bottoms; the middle underframe lifting device comprises a middle upper underframe, a middle upper underframe lifting device and an upper underframe locking device; an upper frame lifting device is arranged between the concave bottom and the middle upper layer underframe; the middle upper underframe lifting device is used for controlling the middle upper underframe to vertically lift; the number of the middle upper underframe locking devices is at least four, and the locking devices are uniformly distributed on two sides of the middle upper underframe; the middle upper underframe locking device is used for locking the height of the middle upper underframe; the end underframe lifting device comprises an end upper underframe and an end upper frame control device; the end upper underframe corresponds to a high bottom, four end upper frame control devices are arranged between the high bottom and the end upper underframe, and a pair of end upper frame control devices are symmetrically arranged at the front and back positions of the end upper underframe; the end upper frame control device comprises an end upper frame lifting device, a multi-stage telescopic sleeve and an end upper frame rotating device; the end upper frame lifting device is used for controlling the lifting of the end upper layer underframe; an end upper frame lifting device is arranged in the multi-stage telescopic sleeve; the multistage telescopic sleeve is used for locking the length of the overhead lifting device; the end upper frame rotating device is used for driving the multistage telescopic sleeve to turn over along the length direction of the lower-layer underframe. According to the structure, the middle part of the lower underframe is provided with the concave bottom, the two ends of the lower underframe are provided with the high bottoms, and the concave bottom and the high bottoms are connected through the inclined bottoms; when the middle upper underframe above the concave bottom is driven by the upper underframe lifting device to rise by a certain height and the four upper underframe lifting devices control the end upper underframe to rise, the large SUV cars to be transported pass through the high bottom and the inclined bottom to the concave bottom, and some higher large SUV cars can be parked on the concave bottom, so that the space accommodating capacity of the transport vehicle is improved by the concave bottom; after the ascending height of the middle upper underframe is determined, the middle upper underframe is locked by the middle upper locking device, so that the pressure of the automobile parked on the middle upper underframe is avoided when the middle upper lifting device does not work. When the middle upper underframe is driven to descend by the middle upper underframe lifting device, the middle upper underframe can be finally supported on the lower underframe; the middle upper frame lifting device is always positioned between the concave bottom and the middle upper layer underframe.

As can be seen from the above structure, the lower underframe 1 is provided with a concave bottom 5 in the middle, and high bottoms 20 are arranged at two ends, and the concave bottom 5 and the high bottoms 20 are connected through an inclined bottom 21; when the middle upper underframe 2 above the concave bottom 5 is driven by the upper underframe lifting device 3 to rise by a certain height and the four upper underframe lifting devices 22 control the upper underframe 19 at the end to rise, the large SUV cars ready for transportation pass through the high bottom 20 and the inclined bottom 21 to the concave bottom 5, some higher large SUV cars can be parked on the concave bottom 5, and the concave bottom 5 improves the space accommodating capacity of the transport vehicle; after the ascending height of the middle upper underframe 2 is determined, the middle upper underframe 2 is locked by the middle upper locking device 4, so that the pressure of the automobile parked on the middle upper underframe 2 is avoided when the middle upper lifting device 3 does not work.
