Specific embodiment

The embodiment of the utility model is illustrated below according to attached drawing.

As shown in Figures 1 to 4, a kind of automatic rail tractor, including the second track 13 and car body 14, car body 14 includes rectangular The panel 7 of shape and the second wheel 8 being rotatably arranged at 7 four angles of panel, via is offered on panel 7.Second track 13 For 13 monomer composition of the second track that I-shaped track, the second track 13 are set up in parallel by two, the inside one of the second wheel 8 Be connected with cricoid wide diameter portion, when the second wheel 8 on the second track 13 when rolling, wide diameter portion for prevent the second wheel 8 from It derails on second track 13.Second track 13 is arranged on a base station 4, is offered on base station 4 parallel with the second track 13 Groove 6, and groove 6 is located between two 13 monomers of the second track.It is further fixedly arranged in groove 6 along 6 direction of groove and extended Conductive trough 12 and transmission device stent 11, conductive trough 12 is for laying various supply lines.

The driving device that car body 14 is driven to move is provided on car body 14, hangs drawing automatically for other vehicles for drawing Hang device 19 and PLC controller, and driving device and draw the lower section that hang device 19 is arranged at panel 7 automatically.

Driving device includes driving motor 16 and deceleration unit 17, and driving motor 16 is electrically connected with PLC controller, driving electricity There are two sprocket wheels 18 by the driving of deceleration unit 17 for machine 16.It is each provided with a driving chain 9 on two cell walls of groove 6, two A driving chain 9 is meshed respectively with two sprocket wheels 18, and one end of two driving chains 9 is each provided with a chain stretching device 10, chain stretching device 10 is fixed on transmission device stent 11.

The automatic hang device 19 that draws includes actuating unit and telescoping mechanism.Actuating unit includes the driving being arranged on car body 14 Motor 21, drive motor 21 are electrically connected with PLC controller, and drive motor 21 is fixed on a motor bracket 20, motor Stent 20 is fixedly connected with car body 14, and fixing sleeve is equipped with drive gear 24 on the output shaft of drive motor 21.Telescoping mechanism includes Fixed seat 23 setting up and down and sleeve 25, fixed seat 23 are cylindrical in shape structure, are slided up and down in fixed seat 23 and are provided with traction Bar 22, the lower end of draw bar 22 offer the T-shaped cavity 30 of vertical section.It is slided up and down in sleeve 25 and is provided with rack circle 27, the diameter of rack circle 27 is less than the diameter of draw bar 22.It offers to expose rack circle 27 on the side wall of sleeve 25 Through hole, drive gear 24 is meshed through through hole with rack circle 27, the upper end of rack circle 27 by connect bolt 26 with The lower end of draw bar 22 is connected；The shank of bolt of connection bolt 26 is fixedly connected with rack circle 27, connects the bolt of bolt 26 Head 31 is inserted into cavity 30, and leaves gap between 30 inner wall of bolt head 31 and cavity.The top and bottom of sleeve 25 are each It sets there are one oil-free bushing 28, rack circle 27 is passed through from two oil-free bushings 28, reduced by two oil-free bushings 28 Friction when rack circle 27 slides up and down in sleeve 25 can either reduce the frictional dissipation of sleeve 25 and rack circle 27, Also generated heat in the course of work can be reduced, so as to extend the automatic service life for drawing hang device 19, in order to further Effect is promoted, the diameter of rack circle 27 can be made to be slightly less than the interior warp of sleeve 25.It is also fixed on the inner wall of 25 lower end of sleeve Snap ring 29 is provided with, snap ring 29 is for preventing rack circle 27 from generating radial missing, so as to avoid rack circle 27 to two nothings Oily bushing 28 generates extruding, so as to extend the service life of two oil-free bushings 28.

As shown in Fig. 5 to 8, when in use, the top of tractor 5, cargo will be arranged on for the cargo vehicle 1 of bearing goods Vehicle 1 includes a rectangular support board and is rotatably arranged on several first wheels 2 of two long sides of support board, in support board On be further opened with one and draw hanging hole 15.Then first track 3 is set on base station 4, the first track 3 by two be set up in parallel One track monomer composition, two the first track monomers are located at the both sides of tractor 5 respectively, and the first wheel 2 coordinates with the first track 3 Cargo vehicle 1 is enable to be moved back and forth on base station 4, and the moving direction of cargo vehicle 1 is identical with the moving direction of tractor 5. One end of first track 3, cargo vehicle 1 complete the loading of cargo, then control driving motor 16, driving motor by PLC controller 16 control two sprocket wheels 18 to rotate by deceleration unit 17, because driving chain 9 is fixed, therefore the sprocket wheel 18 rotated can edge Driving chain 9 moves, and then tractor 5 is driven to move.After tractor 5 is moved to the lower section of cargo vehicle 1, controlled by PLC Device control drive motor 21 is run, and drive motor 21 drives drive gear 24 to rotate, and then rack circle 27 is driven to move up, Rack circle 27 is jacked up draw bar 22 by connecting bolt 26 upwards, makes the upper end of draw bar 22 successively from the mistake on panel 7 Drawing in hanging hole 15 on hole and support board passes through, and completes tractor 5 and draws extension to cargo vehicle 1.The driving of PLC controller control afterwards Device is run, and makes tractor 5 that cargo vehicle 1 be driven to move.After the other end for reaching the first track 3, PLC controller passes through control Drive motor 21 processed makes draw bar 22 move down and depart from from drawing in hanging hole 15, completes the separation of tractor 5 and cargo vehicle 1.

Because cargo is carried on cargo vehicle 1, therefore quality and the resistance of movement are all larger, draw in tractor 5 and hang goods When object 1 synchronizing moving of vehicle, connection bolt 26 needs to bear the resistance in 1 operational process of cargo vehicle, particularly in tractor 5 When starting and braking, connection bolt 26 will bear the pressure of inertia belt, be very easy to damage.It is set by the way that bolt 26 will be connected In cavity 30, and connect and leave gap between the inner wall of bolt 26 and cavity 30, it can be when tractor 5 be started and braked Play the role of buffering, to extend the service life of connection bolt 26.

It should also be noted that, herein, relational terms such as first and second and the like are used merely to one Entity or operation are distinguished with another entity or operation, without necessarily requiring or implying between these entities or operation There are any actual relationship or orders.Moreover, term " comprising ", "comprising" or its any other variant are intended to contain Lid non-exclusive inclusion, so that process, method, article or equipment including a series of elements not only will including those Element, but also including other elements that are not explicitly listed or further include as this process, method, article or equipment Intrinsic element.In the absence of more restrictions, the element limited by sentence "including a ...", it is not excluded that Also there are other identical elements in process, method, article or equipment including the element.
