Description

Technical Field

[0001] The invention relates to the technical field of aerial railway maintenance tracks, and in particular to an aerial railway maintenance track which is convenient to open and close. Background Art

[0002] With the changes of the times, the process of urbanization is accelerating, and therefore, the scale of cities is growing rapidly. With the acceleration of the pace of life and the sharp increase in the number of urban population, people's travel volume is increasing. This increase in travel volume is not limited to a single city, but has spread between cities and rural areas, and between cities. The existing transportation can no longer meet people's travel needs, and major cities in the world have varying degrees of car congestion. Therefore, people have been looking for various ways to solve the traffic congestion problem caused by the growing amount of travel. Since the aerial rail train moves ground traffic to the air, it has the advantages of little impact on ground buildings and facilities during the construction process, fast train running speed after opening, flexible track laying, and no pollution to the environment during operation.

[0003] The utility model patent [patent number 201720580366.X] previously applied by our company discloses a kind of empty railway maintenance track with adjustable gauge or fully open, including a frame, on which an opening and closing track is arranged; the opening and closing track includes left and right opening and closing sub-tracks, and the left and right opening and closing sub-tracks can move left and right at the same time in the horizontal direction to change the gauge of the opening and closing track or make the opening and closing track fully open. The empty railway maintenance track with the above structure has a gauge that can be adjusted or fully opened as needed, so that it is suitable for empty railway locomotives and empty railway dismantling work of different specifications. Its adjustment method is simple and convenient, and the adjustment structure is easy to set and operate. However, in actual use, since the roller is set in the middle part of the beam, the side of the roller contacts the beam, resulting in an excessively large contact surface. During use, the roller often gets stuck, making the opening and closing of the opening and closing track not smooth. At the same time, once stuck, the beam needs to be opened to repair the roller, which requires a long maintenance time. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] Embodiment 1, an air-rail integrated operation train inspection line with convenient opening and closing, comprises a bracket 100, an opening and closing track 200 that can be opened and closed is arranged above the bracket 100, a crossbeam 110 is arranged above the bracket 100, the opening and closing track 200 comprises two opening and closing rail bodies 220 that cooperate with each other and hangers 210 fixedly arranged at both ends of the opening and closing rail bodies 220, rollers are arranged on the hangers 210, a slide rail 111 that cooperates with the rollers is arranged on the top of the crossbeam 110, a driving device for driving the hanger 210 to open to both sides along the crossbeam 110 is also arranged on the crossbeam 110, the fixed plate 212 and another hanger 210 are provided with mutually cooperating latch holes, a fixing pin is arranged in the latch hole, a bridge crane 300 is erected on every two adjacent crossbeams 110, By setting up a bridge crane 300, the parts that need to be replaced can be hoisted without manual handling. A fixed rail 500 is set on one side of the opening and closing rail 200. The driving device includes sprockets 430 set at both ends of the beam 110 and a chain 420 connected between the two sprockets 430. The chain 420 is wound between the two sprockets 430 to form an upper chain 420 and a lower chain 420. The two hangers 210 located at the same end of the two opening and closing rail bodies 220 are both provided with connecting rods 410, and the two connecting rods 410 are respectively connected to the upper chain 420 and the lower chain 420. A double-output shaft motor 400 is set between two adjacent beams 110, and the two main shafts of the double-output shaft motor 400 are respectively connected to the sprockets 430 on the opposite sides of the two beams 110.

[0030] The specific working principle is as follows: the maintenance track becomes openable, which is convenient for maintenance workers to enter the top of the empty railway, increases the workers' operating space, and facilitates maintenance. By setting the roller on the top of the beam 110, the roller of the opening and closing track 200 will not get stuck when it is opened, which is convenient for determining the track opening distance according to the roller position. The double-output shaft motor 400 drives a pair of sprockets 430 on the two beams 110 to rotate and then drives the chain 420 to move, wherein the upper chain 420 and the lower chain 420 move in opposite directions, and the connecting rod 410 pulls the hanger 210 to move along the beam 110, thereby driving the opening and closing track 200 between the pair of beams 110 to open. Only one motor is needed to drive the entire opening and closing track 200 to open, so that the two ends of the opening and closing track 200 open synchronously, and the track will not be stuck.
