Detailed Description
The invention is further described below with reference to examples and figures:
As shown in fig. 1, 11 and 12, in order to enable the place change of the train in the production and assembly process, a dummy car 44 replacing a bogie needs to be additionally installed under a carriage 43 to be transferred, and two place dummy car rails 11 are built on the place to be transferred to allow the dummy car wheels 45 on two sides of the dummy car 44 under the carriage 43 to run. Because the carriage is long, the turning radius of the false car rail 11 is very large, and the false car rail 11 cannot turn in a sharp way in a limited place, so that a moving platform needs to be built in the place, and the moving platform can build the moving rail 102 which forms an angle of 90 degrees with the false car rail 11, so that the moving rail 102 extends to a carriage destination area. Meanwhile, the on-frame false trolley rail 10 for the false trolley wheels 45 on two sides of the false trolley 44 to run is built on the trolley, and when the on-frame false trolley rail 10 is in butt joint with the site false trolley rail 11, the carriage 43 can be pushed from the site false trolley rail 11 to the on-frame false trolley rail 10, the carriage 43 is pulled to the trolley, and then the carriage is transferred to a target area along the trolley rail 102 by the trolley.
Since the car cannot be directly removed after being transferred to the destination area by the transfer table, it is necessary to construct the destination area false car rail 12 on the site of the destination area, and the destination area false car rail 12 may or may not be located on the same side of the transfer table as the site false car rail 11.
As shown in fig. 1, 2,3, 11 and 12, a wagon platform integrated with a traction loading and unloading mechanism is provided with a platform 1, a wagon wheel 101 arranged at the bottom of the platform 1, two fake wagon rails 10 arranged on the platform 1, wherein the platform 1 is provided with a traction mechanism, and the traction mechanism comprises traction pieces which can extend out of any one of two sides of the platform 1; when the on-frame false car rail 10 is aligned with the site false car rail 11, a traction member extending out of the side of the gantry 1 can pull the carriage 43 stopped on the site false car rail 11 onto the gantry 1; when the overhead false trolley rail 10 is aligned with the destination false trolley rail 12, the traction member is able to push the car 43 stopped on the overhead false trolley rail 10 onto the destination false trolley rail 12. In this way, the transfer loading and unloading of the carriage 43 can be completed by integrating the traction mechanism arranged on the transfer table, and two special traction devices for loading and unloading are not required to be arranged on the site, so that a great deal of cost is saved. Meanwhile, since the traction member can extend out of either side of the rack 1, the transfer platform of the integrated traction loading and unloading mechanism can be adapted regardless of the place of the transfer platform on which the carriage 43 to be transferred is located and regardless of the place of the transfer platform on which the destination to be transferred is located.

When the front drive shaft 36 and the rear drive shaft 37 rotate synchronously in the same direction, the front cam 34 and the rear cam 35 both rotate from the small-diameter arc surface 38 to the large-diameter arc surface 39, and thus both the front link power arm 802 and the rear link power arm 902 rotate upward, and the front link resistance arm 801 and the rear link resistance arm 901 rotate downward. The front rod piece resistance arm 801 which rotates downwards forces the front hanging end 601 of the front clamping piece 6 to be lower than the body of the false trolley 44 through the front traction arm 22, so as to be separated from the connection with the false trolley 44; the downward rotating rear rod resistance arm 901 forces the rear hanging end 701 of the rear clip 7 to descend below the body of the false trolley 44 through the rear traction arm 23, and is disconnected from the false trolley 44.
The arm end of the front rod piece power arm 802 is provided with a front movable arm pulley 8021, and when the front cam 34 rotates, the front rod piece power arm 802 is stressed by rolling contact with the outer peripheral surface of the front cam 34 through the front movable arm pulley 8021; the arm end of the rear rod power arm 902 is provided with a rear movable arm pulley 9021, and when the rear cam 35 rotates, the rear rod power arm 902 is stressed in rolling contact with the outer peripheral surface of the rear cam 35 through the rear movable arm pulley 9021. In this way, the rotational resistance of the front cam 34 and the rear cam 35 can be reduced.
One coupling device may be provided on the traction frame, or two coupling devices may be provided corresponding to two false dollies 44 under the carriage 43.
The application principle of the arrangement is as follows:
As shown in fig. 1 to 12, the transfer table is moved so that the two on-frame traction rails 13 are respectively butted with the two site traction rails 14, and at the same time, the two on-frame false car rails 10 are respectively butted with the two site false car rails 11.
The first driving gears 4 arranged at the two ends of the transfer platform are driven by the first driving motor 5, so that the first driving gears 4 at the two ends rotate in the same direction, acting force is applied to the first driving racks 3, and the traction frame 2 is pushed along the upper traction rail 13 to the carriage 43 stopped on the false-floor trolley rail 11.
As the traction frame 2 advances toward the carriage 43, the first drive gear 4 away from the carriage 43 disengages from the first drive gear 3, and the traction frame 2 continues to advance toward the carriage 43 by the force exerted by the first drive gear 4 closer to the carriage 43.
When one end of the traction frame 2 close to the carriage 43 drives away from the traction rail 13 on the frame, the traction frame is immediately driven into the site traction rail 14, so that the traction frame 2 is pushed into the underground of the carriage 43, and the front end face of the false trolley 44 can be hung backwards by lifting the front hanging end 601 of the front clamping piece 6 of the connecting and hanging device on the traction frame 2 to the limit height; the rear end face of the false trolley 44 can be hung forward by raising the rear hanging end 701 of the rear clip 7 of the hitch to a limit height. At this time, the drive gear one 4 near the carriage 43 is kept engaged with the drive rack one 3.
Then, the first driving gear 4 rotates reversely to pull the traction frame 2 back to the transfer table and pull the carriage 43 forward to the rack 1 of the transfer table, so that the traction frame 2 finishes loading traction of the carriage 43.
The carriage 43 is pushed to the destination area along the carriage moving rail 102 by the carriage moving platform, so that the two traction rails 13 on the two frames are respectively butted with the two false trolley rails 12 on the zone, and meanwhile, the two false trolley rails 10 on the two frames are respectively butted with the two false trolley rails 12 on the zone.
After the carriage 43 is pushed to the destination area along the carriage moving rail 102, the first driving gears 4 arranged at the two ends of the carriage are driven by the first driving motor 5, so that the first driving gears 4 at the two ends rotate in the same direction, acting force is applied to the first driving racks 3, the traction frame 2 drives to the destination area false carriage rail 12 along the on-frame traction rail 13, and the carriage 43 is pushed to the destination area false carriage rail 12.
At this time, the front cam 34 and the rear cam 35 are rotated until the large-diameter arc surface 39 of the front cam 34 contacts with the arm end of the front lever power arm 802 to lower the front hanging end 601 of the front clip 6 from the limit height to the lowest point; the large diameter arc surface 39 of the rear cam 35 contacts with the arm end of the rear rod power arm 902 to enable the rear hanging end 701 of the rear clamping piece 7 to descend from the limit height to the lowest point.
Finally, the traction frame 2 is retracted to the rack 1, and the transfer of the carriage 43 is completed once.
The above embodiments are only for the purpose of more clearly describing the present invention and should not be construed as limiting the scope of the present invention, and any equivalent modifications should be construed as falling within the scope of the present invention.
