Track switching apparatus for rail trolleys

A track switching apparatus for rail trolleys, comprising:

• at least one linear track having a first power transmission rail strip and a first supporting rail strip parallel to the first power transmission rail strip;
• a curved track connected to the at least one linear track and having a second power transmission rail strip and a second supporting rail strip parallel to the second power transmission rail strip;
• a first switching region formed at a connection region of the first power transmission rail strip of the linear track and the second power transmission rail strip of the curved track;
• a first switching unit disposed in the first switching region and having a first base station, at least one first sliding rail disposed on the first base station, a first sliding seat disposed slidably on the at least one first sliding rail, a first movement power source disposed on the first base station and having a first transmission part connected to the first sliding seat, a first connection segment having a linear shape for actively connecting to or separating from the first power transmission rail strip of the linear track, and a second connection segment having a curved shape disposed on the first sliding seat at an interval for actively connecting to or separating from the second power transmission rail strip of the curved track;
• and
• plural first guide wheel assemblies and each of which has a first fixing seat and connects to an end bottom region of the first supporting rail strip of the linear track adjacent to a second switching region,
• wherein at least one side of an intersection of the first supporting rail strip of the linear track and the second power transmission rail strip of the curved track is provided with the second switching region,
• wherein the second switching region is further provided with a second switching unit having a second base station, at least one second linear sliding rail disposed on the second base station, a second sliding seat disposed slidably on the at least one second linear sliding rail, a second movement power source disposed on the second base station and having a second transmission part connected to the second sliding seat, and a third connection segment on the second sliding seat for actively connecting to or separating from the first supporting rail strip of the linear track,
• wherein the first fixing seat of each of the plural first guide wheel assemblies is further provided with a stand at a bottom thereof and at least one first sliding rail press reducing gear disposed at one lateral thereof and protruded from the second switching region for attaching to or detaching from a bottom of the third connection segment.
