Abstract
The invention discloses a telescopic freight car which comprises a fixed car, a movable car arranged on the fixed car in a longitudinal reciprocating motion mode along the fixed car, a telescopic driving device arranged on the fixed car, and a locking device for locking or loosening the fixed car and the movable car. The motion output end of the telescopic driving device is connected with the movable car. When light cargo needs to be loaded, the locking device is loosened, the movable car is driven to extend backwards through the telescopic driving device, and then the movable car and the fixed car are locked through the locking device so as to increase car size and avoid effect on traffic safety caused by stacking. In addition, car length can be shortened so that parking space can be saved. The telescopic freight car is simple in structure, low in implementation cost, and practical in the field of light trucks.
Description
Technical field
The present invention relates to automobile component, particularly a kind of boxcar.
Background technology
At present, the compartment of lorry is generally regular length, lorry with this structure compartment has the following disadvantages: 1) because the compartment volume is fixed, often that stacks of cargo is high when some light cargoes of delivery, easy superelevation, affect traffic safety, during as light cargoes such as delivery stalk, cottons, common cargo height is far away higher than height of car; 2) as increasing cargo capacity, need add trailer carriage, not only cost is higher, and troublesome poeration, adds trailer carriage and also need take the parking stall when not using; 3) car length can not shorten, and is unfavorable for saving the parking stall.
For above-mentioned deficiency, need existing boxcar is improved, it can be elongated or shortened as required, loading is flexible, and saves the parking stall.
Summary of the invention
In view of this, the invention provides a kind of telescoping boxcar, this compartment adopts stretching structure, effectively solve existing compartment volume immutable cause delivering light cargo inconvenience and stop take the more technical matters in parking stall.
The present invention solves the problems of the technologies described above by following technological means:
Telescoping of the present invention boxcar, comprise fixing compartment, can be arranged at along the mode that fixing compartment vertically moves back and forth movable compartment on fixing compartment, be arranged at the retractable driving device on fixing compartment and be used for locking or to unclamp the fixedly latching device in compartment and movable compartment, the movement output end of described retractable driving device is connected with movable compartment.
Further, described retractable driving device comprises hydraulic column, and the two ends of described hydraulic column are connected with movable compartment with fixing compartment respectively.
Further, compartment and movable compartment are hinged respectively with fixedly at the two ends of described hydraulic column.
Further, described hydraulic column is two, and symmetrical along the compartment center line.
Further, described latching device is push bolt, is provided with vertical chute on described movable compartment, and push bolt passes after chute with fixing compartment and is threaded.
beneficial effect of the present invention: telescoping of the present invention boxcar, comprise fixedly compartment, can be arranged at along the mode that fixing compartment vertically moves back and forth the movable compartment on fixing compartment, be arranged at the retractable driving device on fixing compartment and be used for locking or unclamp the fixedly latching device in compartment and movable compartment, the movement output end of described retractable driving device is connected with movable compartment, when needing to load light cargo, unclamp latching device, driving movable compartment by retractable driving device stretches out backward, lock movable compartment and fixing compartment by latching device again, to increase the compartment volume, avoid piling the high traffic safety that affects, in addition, car length can shorten, also be conducive to save the parking stall.The present invention is simple in structure, and implementation cost is low, has stronger practicality in underloading lorry field.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
Fig. 2 is lateral plan of the present invention.
The specific embodiment
the present invention is described in detail below with reference to accompanying drawing, as shown in the figure: the telescoping boxcar of the present embodiment, comprise fixedly compartment 1, can be arranged at along the mode that fixing compartment 1 vertically moves back and forth the movable compartment 2 on fixing compartment 1, be arranged at the retractable driving device on fixing compartment 1 and be used for locking or unclamp the fixedly latching device in compartment 1 and movable compartment 2, the fixing fore-and-aft direction that vertically refers to lorry in compartment, the movement output end of described retractable driving device is connected with movable compartment 2, being used for driving movable compartment 2 moves backward elongation or moves forward shortening, to change car wagon box volume, adapt to different operatings needs.
As further improvement in the technical proposal, described retractable driving device comprises hydraulic column 3, are connected with movable compartment with fixing compartment 1 respectively and are connected in the two ends of described hydraulic column 3, in the present embodiment, the base of hydraulic column is connected to fixedly on the compartment, the piston nose of hydraulic column is connected with movable compartment, and is simple in structure, is easy to control.Certainly, retractable driving device is not limited only to hydraulic column, also can adopt as modes such as motor-driven screw mandrel, motor-driven transmission devices and control moving forward and backward of movable compartment, all can realize purpose of the present invention.
As further improvement in the technical proposal, compartment 1 and movable compartment 2 are hinged respectively with fixedly at the two ends of described hydraulic column 3, can prevent that in the movable compartment moving process, the resistance skew to hydraulic column causes hydraulic actuating cylinder to damage.
As further improvement in the technical proposal, described hydraulic column 3 is two, and symmetrical along the compartment center line, makes movable compartment stressed evenly, prevents sideslip in moving process and damages the parts such as guide rail.
As further improvement in the technical proposal, described latching device is push bolt 4, is provided with vertical chute 2a on described movable compartment 2, and push bolt 4 passes after chute 2a with fixing compartment 1 and is threaded, after tightening push bolt, bolt cap with movable compartment and fixedly the compartment compress, can realize locking, simple in structure, easy to operate, certainly, latching device also can adopt other structures such as hydraulic locking apparatus, all can realize purpose of the present invention.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not breaking away from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
