Problems solved by technology

Its disadvantages: the active beam is connected with the driven beam through the rotating table, and the No. 6 and No. 7 supports are respectively hinged shaft devices. This structure only releases the Z-direction rotation degree of freedom of the beams on both sides, and overcomes the temperature deviation between the upper and lower sides. However, the side bending caused by the lateral temperature difference still exists. When the temperature difference between the two sides of the web is large, the lateral alignment locking device still needs a relatively large locking force

Embodiment 1

[0045] Embodiment 1: with reference to attached Figure 1-8 . An intermediate slewing device for urban rail transit crossing lines, the butt joints of the first rotating beam 6 and the second rotating beam 10 are in a boss overlapping structure and are located on the base 1 through the slewing platform 8, the first rotating beam 6 and the second The lower part of the non-joint part of the rotating beam 10 is respectively equipped with a mobile trolley mechanism 12 and is located on the base 1, and the bottoms of the first rotating beam 6 and the second rotating beam 10 are respectively provided with driving guide grooves 11, and one end of the two driving arms 5 is respectively located on In the driving guide groove 11, the other ends of the two driving arms 5 are respectively connected to the power output ends of the respective reducers 4, and the power input ends of the reducer 4 are respectively connected to the power output ends of the double-headed motor reducer 7 through...

Embodiment 2

[0047] Embodiment 2: On the basis of Embodiment 1, a method for eliminating the side bending and arching of the beam body in the middle turning device of an urban rail transit crossing line, the first rotating beam 6 and the second rotating beam 10 are two beams. In the form of connection, the support pins on both sides of the first rotating beam 6 and the second rotating beam 10 connect the first rotating beam 6 and the second rotating beam 10 together to release the Z-direction rotation constraint, and the hinge device connects the first rotating beam 6 and the second rotating beam 10 are consolidated together, and the Y-direction rotation constraint is released. The side bending deformation and arching deformation of the beam body due to uneven sunlight become the deformation of the two short beams, and remain unchanged in other structures. In the case of a single long straight beam, the arch height is reduced compared to a single long straight beam, which is about 1 / 4 of a ...

Abstract

The invention relates to an urban railway double-crossover middle turning device and a method for eliminating lateral bending and upwarping of a beam body. A butt joint part between a first rotary beam and a second rotary beam is of a lug boss lap-joint structure and is located on a base through a rotary table, the lower part of a non-butt-joint part of each of the first rotary beam and the second rotary beam is provided with a trolley moving mechanism, the trolley moving mechanisms are located on bases, a drive guide slot is arranged at the bottom of each of the first rotary beam and the second rotary beam, one ends of two drive arms are respectively located in the drive guide slots, the other ends of the two drive arms are respectively connected with a power output end of a respective reduction gear, the power input ends of the reduction gears are respectively connected with a power output end of a double-end motor reduction gear through a transmission shaft and a transmission shaft support frame, two locking frames are respectively located on the bases for supporting the non-butt-joint parts of the first rotary beam and the second rotary beam, and two locking mechanisms are respectively located at the back parts of the non-butt-joint parts of the first rotary beam and the second rotary beam and are respectively matched with the locking frames in a locking or opening manner.

Description

technical field [0001] The invention relates to a method that can not only eliminate and reduce the phenomenon of side bending and upward arching of the beam body due to uneven sunlight, but also enable the middle rotary device to have better synchronization between the two sections of the beam and rotate at the same time. After the device is rotated in place, the locking device does not need to overcome the deformation force caused by the side bending. The urban rail transit crossover intermediate slewing device and the method for eliminating the side bending and arching of the beam body belong to the manufacturing field of the rail transit crossover intermediate slewing device. Background technique [0002] Japanese patent: a track divergence device (central slewing truss JP2005-36442A), see attached Figure 9 and 10 . Labels in the figure: 1-mobile trolley, 2-lock frame, 3-active beam, 4-switching device, 5-rotary table, 6-active beam support, 7-driven beam support, 8-dr...
