Technical Field
[0001] The utility model relates to the technical field of train connection, in particular to a movable connection structure for a track sightseeing train. Background Art
[0002] Train movable connection device refers to an important device used on railways or rail vehicles, and is one of the components of the railway vehicle system. It is used to connect the completed railway trains or rail vehicles to ensure that the power car in the locomotive or fixed train group can drive the unpowered railway passenger car or railway freight car when it starts, so that they can be synchronously linked under its physical force, thereby ensuring the smooth operation of the entire rail train.
[0003] The design and function of the movable connection structure used for rail sightseeing trains are mainly to ensure the stability and safety of the train during operation, while providing a good passenger experience. There are two main traditional connection methods: hook-and-loop and bolt-type. The hook-and-loop connection device is simple and fast, suitable for connecting multiple carriages, but its connection strength is low and cannot withstand the traction of high-speed trains; the bolt-type connection device has a high connection strength and is suitable for high-speed trains, but the connection time is long and is suitable for connecting two carriages.
[0004] Considering that sightseeing trains need to carry people, riding comfort needs to be given extra consideration. In order to ensure the stability of the connection, traditional connections do not have a buffer structure, which can easily cause serious collisions during starting, speed regulation, and braking, especially in curves and sections with poor line conditions, which can easily lead to derailment accidents. Therefore, an active connection structure for rail sightseeing trains is proposed. Utility Model Content
[0005] In view of the shortcomings of the prior art, the utility model provides a movable connection structure for a rail sightseeing train, which has the advantages of good stability and high reliability, and solves the problem that the traditional sightseeing train movable connection device has no buffer structure and the connection stability is not high.
[0006] In order to achieve the above-mentioned purpose of good stability and high reliability, the utility model provides the following technical solutions: a movable connection structure for a rail sightseeing train, comprising a rear seat, a connecting assembly arranged on the side of the rear seat, and a locking assembly arranged on the side of the connecting assembly.
[0007] Furthermore, the connecting assembly includes a connecting cylinder fixedly installed on the side of the rear seat, an adjusting plate rotatably connected to the inner wall of the connecting cylinder, a shock-absorbing spring fixedly installed on the side of the adjusting plate, a damper fixedly installed on the side of the adjusting plate, a supporting plate fixedly installed on the side of the shock-absorbing spring, a locking rod fixedly installed on the side of the supporting plate, a plurality of locking blocks fixedly installed on the side of the locking rod, a locking cylinder movably connected to the inside of the connecting cylinder, and a locking pin fixedly installed on the inner wall of the locking cylinder.
[0008] Further, the side of the damper is fixedly installed with the side of the support plate, and the sides of both the support plate and the adjustment plate are slidably connected to the inner side wall of the connecting cylinder.
[0009] Further, the locking blocks on the side of the locking rod are divided into two parts. A limit card slot for cooperating with the locking pin is provided in the middle of the locking block, and the two side surfaces of the locking pin are rotatably connected to the inner side wall of the limit card slot.
[0010] Further, the side of the locking block is slidably connected to the inner side wall of the locking cylinder, and a limiting notch for cooperating with the locking bolt is provided on the side of the end of the locking block located outside the locking rod.
[0011] Further, the locking assembly includes a locking bolt movably connected to the top of the locking cylinder, a locking nut threadedly connected to the bottom of the locking bolt, an observation slot provided on the side of the locking cylinder, an adjustment slot provided on the side of the connecting cylinder, and an adjustment bolt fixedly installed on the side of the adjustment plate.
[0012] Further, a special-shaped through hole penetrating the upper and lower side walls is provided at the top of the locking cylinder. The locking bolt is vertically inserted into the special-shaped through hole and is slidably connected to the locking cylinder. A limiting plate with a size larger than the special-shaped through hole is provided at the top of the locking bolt.
[0013] Further, a threaded hole is provided at the bottom of the locking bolt, and the top of the locking nut is threadedly screwed into the threaded hole. The head size of the locking nut is larger than the size of the special-shaped through hole of the locking cylinder.
[0014] Further, the adjustment bolt is of an L-shaped structure, and the adjustment bolt longitudinally penetrates the adjustment slot and is slidably connected to the inner side wall of the adjustment slot.
[0015] Compared with the prior art, the present utility model provides a movable connection structure for a track sightseeing train, and has the following beneficial effects:
[0016] 1. For the movable connection structure for the track sightseeing train, by rotating the adjustment bolt to the vertical state, the rotation of the adjustment bolt drives the rotation of the adjustment plate, which drives the rotation of the damper and the shock-absorbing spring, thereby driving the rotation of the support plate. The rotation of the support plate drives the rotation of the locking rod and the locking block. At this time, the locking blocks on both sides of the locking rod rotate to the vertical state. Then, the locking cylinder is inserted into the inside of the connecting cylinder. At this time, the locking rod drives the locking block to be embedded into the inside of the locking cylinder. By observing the position of the locking rod inside the locking cylinder through the observation slot, when the locking pin reaches the notch formed between the locking blocks, rotate the adjustment bolt so that the locking block rotates to the horizontal position to clamp the locking pin, thereby completing the stable connection between the connecting cylinder and the locking cylinder.
[0017] 2. The movable connection structure for rail sightseeing train drives the locking blocks on both sides of the locking rod to reach the horizontal position by rotating the adjusting bolt. At this time, the locking pin is inserted from the special-shaped notch on the top of the locking cylinder, and the locking pin passes through the notch on the side of the locking block and then passes out of the locking cylinder, and then the locking nut is screwed into the bottom of the locking pin. Due to the limitation of the locking pin on the side of the locking block, the locking rod cannot be rotated again, thereby ensuring the stability of the connection between the connecting cylinder and the locking cylinder. When the train is speeding up or braking, the running speeds of the locking cylinder and the connecting cylinder at the front and rear of the car are inconsistent. At this time, the shock-absorbing spring will be squeezed, and the shock-absorbing spring cooperates with the damper to quickly absorb and weaken the impact, thereby solving the problem that the movable connection device of the traditional sightseeing train has no buffer structure and the connection stability is not high.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figures 1-4 In this embodiment, a movable connection structure for a rail sightseeing train includes a rear seat 1, a connection component 2 arranged on a side of the rear seat 1, and a locking component 3 arranged on a side of the connection component 2.
[0025] The connection assembly 2 is provided to realize the connection between the components, and the locking assembly 3 ensures the stability and reliability of the connection.
[0026] In this embodiment, the connecting component 2 includes a connecting cylinder 21 fixedly installed on the side of the rear seat 1, an adjusting plate 22 rotatably connected to the inner side wall of the connecting cylinder 21, a shock-absorbing spring 23 fixedly installed on the side of the adjusting plate 22, a damper 24 fixedly installed on the side of the adjusting plate 22, a support plate 25 fixedly installed on the side of the shock-absorbing spring 23, a locking rod 26 fixedly installed on the side of the support plate 25, a plurality of locking blocks 27 fixedly installed on the side of the locking rod 26, a locking cylinder 28 movably connected inside the connecting cylinder 21, and a locking pin 29 fixedly installed on the inner side wall of the locking cylinder 28.
[0027] By controlling the rotation of the adjusting plate 22 to drive the rotation of the shock-absorbing spring 23 and the damper 24, the rotation of the support plate 25 is driven. The rotation of the support plate 25 drives the locking rod 26 to cooperate with the locking block 27 to rotate inside the locking cylinder 28, so that the limiting card slot in the middle of the locking block 27 is stuck on both sides of the locking pin 29, thereby realizing the connection.
[0028] In this embodiment, the side of the damper 24 is fixedly installed with the side of the support plate 25, and the sides of both the support plate 25 and the adjusting plate 22 are slidably connected to the inner side wall of the connecting cylinder 21.
[0029] The damper 24 cooperates with the shock-absorbing spring 23 to achieve the shock-absorbing effect between the support plate 25 and the adjusting plate 22, thereby weakening the impact inside the connecting device.
[0030] It should be noted that the damper 24 and the shock-absorbing spring 23 will not rotate relative to the adjusting plate 22 and the support plate 25, so that the rotation of the adjusting plate 22 and the support plate 25 can be kept consistent during adjustment.
[0031] In this embodiment, the locking block 27 on the side of the locking rod 26 is divided into two parts. A limiting card slot for cooperating with the locking pin 29 is provided in the middle of the locking block 27, and the two side surfaces of the locking pin 29 are rotatably connected to the inner side wall of the limiting card slot.
[0032] By arranging two parts of the locking block 27 on the side of the locking rod 26, the front and rear parts of the locking block 27 can respectively abut against the locking pin 31 and the locking pin 29. When the locking pin 29 is inserted into the notch formed between the two parts of the locking block 27, a stable connection state can be formed between the connecting cylinder 21 and the locking cylinder 28.
[0033] In this embodiment, the side of the locking block 27 is slidably connected to the inner side wall of the locking cylinder 28, and a limiting notch for cooperating with the locking pin 31 is provided on the side of one end of the locking block 27 located outside the locking rod 26.
[0034] The inner side wall of the locking block 27 is slidably connected to the locking cylinder 28, enabling the locking block 27 to be smoothly inserted into the interior of the locking cylinder 28. The limiting notch and the locking pin 31 provided on the side surface of the locking block 27 can prevent the locking block 27 from rotating, ensuring the stability after connection.
[0035] In this embodiment, the locking assembly 3 includes a locking pin 31 movably connected to the top of the locking cylinder 28, a locking nut 32 threadedly connected to the bottom of the locking pin 31, an observation slot 33 opened on the side surface of the locking cylinder 28, an adjustment slot 34 opened on the side surface of the connecting cylinder 21, and an adjustment bolt 35 fixedly installed on the side surface of the adjustment plate 22.
[0036] The locking pin 31 is provided in cooperation with the locking nut 32 to achieve the stability of the locking pin 31 inside the locking cylinder 28. The observation slot 33 is used to observe the rotation angle of the locking block 27 in real time. The adjustment bolt 35 cooperating with the adjustment slot 34 can achieve the adjustment of the adjustment plate 22.
[0037] In this embodiment, a special-shaped through hole penetrating the upper and lower side walls is opened at the top of the locking cylinder 28. The locking pin 31 is vertically embedded in the special-shaped through hole and is slidably connected to the locking cylinder 28. A limiting plate with a size larger than the special-shaped through hole is provided at the top of the locking pin 31.
[0038] The special-shaped through hole is provided to limit the locking pin 31, so that the locking pin 31 can stably limit the locking block 27 and prevent the locking block 27 from rotating.
[0039] In this embodiment, a threaded hole is opened at the bottom of the locking pin 31, and the top of the locking nut 32 is threadedly screwed into the threaded hole. The head size of the locking nut 32 is larger than the size of the special-shaped through hole of the locking cylinder 28.
[0040] A threaded hole and the locking nut 32 are provided at the bottom of the locking pin 31 for cooperation, so that the locking pin 31 can be stably fixed inside the locking cylinder 28, thus ensuring the stability of the overall structure.
[0041] In this embodiment, the adjustment bolt 35 is of an L-shaped structure. The adjustment bolt 35 longitudinally passes through the adjustment slot 34 and is slidably connected to the inner side wall of the adjustment slot 34.
[0042] The working principle of the above embodiment is as follows:
[0043] By rotating the adjusting bolt 35 to the vertical state, the rotation of the adjusting bolt 35 drives the rotation of the adjusting plate 22, which in turn drives the rotation of the damper 24 and the shock-absorbing spring 23, thereby driving the rotation of the support plate 25. The rotation of the support plate 25 drives the rotation of the locking rod 26, which drives the rotation of the locking block 27. At this time, the locking blocks 27 on both sides of the locking rod 26 rotate to the vertical state. Then, insert the locking cylinder 28 into the inside of the connecting cylinder 21. At this time, the locking rod 26 drives the locking block 27 to be embedded into the inside of the locking cylinder 28. Observe the position of the locking rod 26 inside the locking cylinder 28 through the observation slot 33. When the locking pin 29 reaches the notch formed between the locking blocks 27, rotate the adjusting bolt 35 so that the locking block 27 rotates to the horizontal position to clamp the locking pin 29, thereby completing the stable connection between the connecting cylinder 21 and the locking cylinder 28.
[0044] In addition, after driving the locking blocks 27 on both sides of the locking rod 26 to the horizontal position by rotating the adjusting bolt 35, at this time, insert the locking pin 31 from the special-shaped notch at the top of the locking cylinder 28. The locking pin 31 passes through the notch on the side of the locking block 27 and then passes out of the locking cylinder 28. Then, screw the locking nut 32 into the bottom of the locking pin 31. Due to the limitation of the locking pin 31 on the side of the locking block 27, the locking rod 26 cannot rotate again, thereby ensuring the stability of the connection between the connecting cylinder 21 and the locking cylinder 28. When the train speeds up or brakes, the operating speeds of the locking cylinders 28 and the connecting cylinders 21 at the front and rear of the carriage are inconsistent. At this time, the shock-absorbing spring 23 will be squeezed. The shock-absorbing spring 23 cooperates with the damper 24 to quickly absorb and weaken the impact, thereby solving the problems that the traditional sightseeing train movable connection device does not have a buffer structure and the connection stability is not high.
[0045] All the electrical components mentioned in the text are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed power connection technology will not be elaborated in the text.
