Description

Technical Field

[0001] The utility model relates to the technical field of traffic track beams, in particular to a suspended rail traffic track beam structure. Background Art

[0002] The suspended monorail is referred to as "sky rail". The car body is suspended in the lower open box-type track beam through the bogie. The track beam is erected in the air through columns and piers, thus realizing the safe and smooth operation of the train in the air. The train is suspended under the track beam, and the wheels pass along the inner space of the track beam. The guide wheels, stabilizing wheels and running wheels on the bogie are in contact with the left and right webs and running bottom plates of the track beam respectively to achieve the driving function.

[0003] After searching, the application with patent number 202322510251.1 discloses a suspended rail transit track beam structure, which belongs to the technical field of transportation track beams, including a top beam plate, both sides of the bottom of the top beam plate are fixedly connected with webs, one side of the two webs is provided with two T-shaped grooves, and the two T-shaped grooves are clamped with I-shaped pieces, and the two I-shaped pieces are threaded with a group of fixing bolts, and one end of the two groups of fixing bolts is respectively threaded on one side of the two webs, and the top of the top beam plate is fixedly connected with two fixing frames, and the same U-shaped insert is movably inserted in the two fixing frames;

[0004] Although the track beam structure of the suspended rail transit is clamped on the web by the track frame, and the side plates are slidably connected in the clamping grooves, which facilitates the disassembly and maintenance of the track frame after the track frame is deformed, the track frame of the suspended rail transit track beam structure cannot limit the direction of the wheels, which can easily cause the wheel's travel route to deviate, and when the wheels roll on the track frame, the track frame exerts a large force on the second stud, which can easily cause damage to the second stud.

[0005] Therefore, we propose a suspended rail transit track beam structure. Utility Model Content

[0010] Preferably, a second threaded hole is provided in the middle of the side wall of the track frame, and a first threaded hole is provided at the bottom end of the web, which is opposite to the second threaded hole in position and has the same specifications as the second threaded hole. The internal threads of the first threaded hole and the second threaded hole are fitted with studs, wherein the studs are threadedly fitted in the second threaded hole and the first threaded hole in sequence, so that the track frame can be limited and fixed, thereby preventing the track frame from moving freely on the bottom end of the web.

[0011] Preferably, a U-shaped slot is provided on one side of the top beam plate and the web plate, and a U-shaped clip which is opposite to the U-shaped slot and has the same specification as the other side of the top beam plate and the web plate is provided, and the adjacent U-shaped clips are movably mounted inside the U-shaped slot, wherein the top beam plates at adjacent positions and the web plates at adjacent positions can be connected together by clamping the U-shaped clips at adjacent positions in the U-shaped slots.

[0015] 1. The suspended rail transit track beam structure can be set on the bottom of the web by aligning one end of the track frame with one end of the bottom of the web and then pushing the track frame to one side of the web, and then using the stud threaded sleeve to fit inside the second threaded hole and the first threaded hole. Through the arrangement of the first inclined surface and the second inclined surface, the bottom end of the web can limit the track frame to avoid the track frame from moving laterally along the bottom end of the web, which is beneficial to increase the limiting effect of the track frame and reduce the force on the stud, avoiding the situation where the stud is bent and damaged due to large force, resulting in inconvenience in disassembly. The wheels on both sides of the train can be guided by the third inclined surface to avoid the deviation of the train's running direction, solving the problem that the track frame of the existing device cannot limit the direction of the wheel, which easily leads to the deviation of the wheel's running route and the second stud is easily damaged due to large force;
