detailed description:

In order to facilitate the understanding of those skilled in the art, the structural principles of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

As shown in Figures 1 to 6, a turnout steering mechanism for a suspended monorail rapid transit system includes a track, a main frame 1 and a capstan 3, and the track consists of an upper guide rail 7, a lower guide rail 8 and a guide rail connecting the upper and lower guide rails. The bracket 9 is composed of the capstan wheel 3 sliding on the lower guide rail 8, the capstan wheel 3 is installed on the main frame 1, the carriage 6 is suspended on the main frame 1, and the subframe 2 is installed on the main frame 1. A secondary guide wheel 4 and a magnetic sucker 5 are installed on the frame 2. When a switch is encountered, the magnetic sucker 5 and the upper guide rail 7 generate suction, the auxiliary guide wheel 4 slides on the upper guide rail 7, and a gap is maintained between the magnetic sucker 5 and the upper guide rail 7. Smaller gaps. The magnetic chuck 5 is an electromagnetic chuck or a permanent magnetic chuck. The electromagnetic chuck is connected to the controller, which can be the vehicle control center or the controller of the car itself, and is controlled according to the road sign information. The magnetic chuck 5 used in the present invention is a permanent magnetic chuck, the magnetic circuit of the permanent magnetic chuck is designed into a plurality of magnetic systems, through the relative movement of the magnetic systems, the addition or elimination of the magnetic field strength on the working magnetic pole surface is realized, thereby Suction and unloading are achieved. In order to achieve the purpose of holding and unloading, the permanent magnet chuck is provided with a drive motor 10 that changes the relative position of the magnetic system.

As shown in Figures 1 to 5, two capstan wheels 3 are installed on the main frame 1, two secondary guide wheels 4 are installed on the subframe 2, and a The magnetic chuck 5, the height of the magnetic chuck 5 is lower than the surface in contact with the upper guide rail 7.

The upper guide rail 7 of the present invention is made of better magnetically conductive steel.

The magnetic chuck 5 of the present invention generates a magnetic attraction force on the upper guide rail, and the magnetic attraction force is greater than the total weight of the trolley.

The working process of the switch steering mechanism of the suspended monorail rapid transit system of the present invention is as follows: the main frame 1 is equipped with a capstan 3, the subframe 2 is installed above the main frame 1, and the distance between the subframe 2 and the main frame 1 can change. Secondary guide wheel 4 is contained on the subframe 2. Magnetic sucker 5 is contained in subframe 2 tops. The magnetic chuck 5 is set at the position between the two pair of guide wheels 4, so that when the auxiliary guide wheel 4 is in contact with the upper guide rail 7, a small gap is maintained between the working surface of the magnetic chuck 5 and the upper guide rail 7, and the upper guide rail 7 is the magnetic guide rail 7. For better steel, the magnetic chuck 5 can generate a larger magnetic force on the upper guide rail. The carriage 6 is suspended below the main frame 1.

As shown in FIG. 6 , the upper guide rail 7 and the lower guide rail 8 on the track are set up and down opposite to each other. When a turnout occurs, the upper guide rail 7 is divided into two paths, one road extends along a straight line, and the other extends along the direction of the turnout, and a lower guide rail 8 is provided below the extended upper guide rail 7 . When vehicle travels on the main road, magnetic chuck 5 is closed, and magnetic chuck 5 does not produce suction force to upper guide rail 7, reduces subframe 2 and main frame 1 distance, and auxiliary guide wheel 4 breaks away from upper guide rail 7. The capstan 3 runs on the lower guide rail 8 .

Need to enter the turnout, before entering the turnout, increase the distance between the sub-frame 2 and the main frame 1, the auxiliary guide wheel 4 contacts the upper guide rail 7, and then open the magnetic chuck 5, the magnetic chuck 5 generates a magnetic attraction force on the upper guide rail 7, and the magnetic attraction force greater than the total weight of the trolley. Reduce sub-frame 2 and main frame 1 distance again, capstan wheel 3 breaks away from lower guide rail 8, at this moment is that auxiliary guide wheel 4 runs on upper guide rail 7, enters fork. Switch from the mode of auxiliary guide wheel 4 running on the upper guide rail 7 to the operation mode of the capstan wheel 3 on the lower guide rail 8, increase the distance between the sub-frame 2 and the main frame 1, the capstan wheel 3 contacts the lower guide rail 8, and then close the magnetic chuck 5. The magnetic chuck 5 does not produce magnetic attraction to the upper guide rail 7, and then the distance between the subframe 2 and the main frame 1 is reduced, and the auxiliary guide wheel 4 breaks away from the upper guide rail 7. At this time, the capstan wheel 3 runs on the lower guide rail 8 and enters the main road.
