Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides the following technical solutions: the utility model provides a trolley locomotive, includes unit 1, and unit 1 includes wheel hub 12, outer top subassembly 2 and retrieves subassembly 3, and wheel hub 12 and unit 1 activity link to each other, and outer top subassembly 2 and wheel hub 12 activity link to each other, retrieves subassembly 3 and outer top subassembly 2 activity and links to each other, and unit 1 includes organism 11, and wheel hub 12 bearing connection is in the both sides of organism 11 one end, and outer top subassembly 2 sets up in wheel hub 12's one end.
The working principle is as follows: when the electric locomotive is started, under the driving of external torque, the hub 12 starts to rotate, the exhaust pump 24 is powered on at the moment, the exhaust pump continuously pumps air into the hollow bin 22, the hollow bin 22 is inflated, the large piston 26 moves upwards under the action of air pressure, the ejector rod 25 drives the clamping tooth plate 23 to move outwards, the distance from the clamping tooth plate 23 to the circle center of the hub 12 is larger than the radius of the hub, the hub 12 and the track rub with each other at the moment, the outward-extending clamping tooth plate 23 contacts the ground outside the track, mutual friction is generated between the clamping tooth plate 23 and the ground, the hub 12 at the moment is not easy to idle due to smaller friction force between the hub 12 and the track, and under the condition, the hub 12 can quickly drive the electric locomotive to move, so that the overall starting time of the electric locomotive is shortened.
When the electric locomotive is completely started, the speed of the electric locomotive tends to be stable and fast, the rotating speed of the hub 12 is fast, the small piston 34 is thrown outwards under the action of centrifugal force, the inner rod 35 is driven to move outwards until the inner rod 35 drives the wide plate 38 to move to block the air needle 27, the gas supply inside the hollow cabin 22 is lost, the wide plate 38 moves to be flush with the air needle 27 at most under the blocking of the limiting plate 37, the through hole of the wide plate 38 is opened at the moment, the air suction pump 31 is started, the air inside the hollow cabin 22 is absorbed through the through holes of the hollow cavity 36 and the wide plate 38, the gas inside the hollow cabin 22 is discharged, the pressure is reduced, the large piston 26 drives the clamping plate 23 to retract through the ejector rod 25, and the rotating speed of the hub 12 is prevented from being influenced due to the clamping plate 23 when the hub 12 moves fast.
When wheel hub 12's speed is very fast promptly, the fishback 23 is withdrawed, avoids influencing wheel hub 12 rotational speed, and when wheel hub 12 rotational speed was slow, fishback 23 stretches out, and auxiliary hub 12 rotates fast for the electric locomotive can the quick start with drive over the ramp when starting with climbing.
The electric locomotive can be quickly started and efficiently climbed without influencing the normal running of the electric locomotive.
