Description

Technical Field

[0001] This utility model relates to the field of fastening device technology, specifically a fastening device for preventing derailment of sightseeing trains. Background Technology

[0002] Sightseeing trains, as a unique mode of transportation, primarily serve scenic areas, parks, and resorts. Unlike regular trains and high-speed trains, sightseeing trains are classified as special equipment, with their operating range strictly limited to specific areas and subject to clear speed limits. It's important to note that speed limits for sightseeing trains vary from country to country. Within scenic areas, sightseeing trains not only fulfill their basic transportation function but also provide tourists with a unique experience of leisurely enjoying the scenery along the way. Some sightseeing trains also offer leisure services, further enhancing the tourist experience.

[0003] A Chinese patent with publication number CN214728812U discloses an anti-derailment device for amusement trains. During use, the train body moves along the rails along the wheels inside the bogie. When one or both wheel treads detach from the rail surface, the anti-derailment baffle contacts the anti-derailment device to prevent the wheelset from separating from the rail. During lateral movement, the end face of the anti-derailment baffle contacts the side face of the anti-derailment device to prevent the bogie from moving laterally. These two functions prevent the wheelset from leaving the rail surface in the vertical and horizontal directions, thus completing the anti-tipping function and effectively preventing the wheels from derailing. This fully ensures the safety of passengers and equipment. Currently, most sightseeing trains adopt a structure in which the bogie directly supports the train body, and the steel wheels directly contact the rails fixed on the sleepers.

[0004] Regarding the aforementioned technologies, when the steel wheel leaves the track at a certain angle or tilt, the flat anti-derailment baffle may not be able to completely and effectively block the steel wheel, resulting in poor anti-derailment effect and the steel wheel easily leaving the track. Utility Model Content

[0005] The purpose of this utility model is to provide a derailment prevention and fastening device for sightseeing trains. By using this device, the problem is solved that when the steel wheel leaves the track at a certain angle or in an inclined state, the flat anti-derailment baffle may not be able to completely and effectively stop the steel wheel, resulting in poor anti-derailment effect and the steel wheel easily leaving the track.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sightseeing train anti-derailment fastening device, comprising a mobile platform, the mobile platform including a base, a control platform provided at the lower end of the base, a hydraulic telescopic rod fixedly installed at the lower end of the control platform, a connecting block fixedly installed at the drive end of the hydraulic telescopic rod, two sets of connecting rods rotatably installed at the lower end of the connecting block, one end of the two sets of connecting rods rotatably connected, a U-shaped fixing strip rotatably installed on the outer side of the two sets of connecting rods, the upper end of the U-shaped fixing strip fixedly connected to the connecting block, and a rail slidably installed at one end of each set of connecting rods, the lower end of the rail being fixed. Equipped with fixed plates, both sets of rails have anti-derailment brackets on one side. When the sightseeing train is in use, the moving platform moves along the rails. When one or both wheel treads detach from the rail surface, the control platform receives the command and controls the hydraulic telescopic rod to move downward, squeezing the two sets of connecting rods. The downward compression of the connecting rods creates pressure on the rails, preventing the wheelsets from detaching from the rails. When turning, the anti-derailment brackets prevent the train from deviating from the rail surface in the left or right direction and tipping over. This effectively prevents the anti-derailment brackets from detaching from the rails, ensuring the safety of passengers and equipment.

[0007] Preferably, each of the two sets of connecting rods is equipped with a friction roller at one end that is far apart from the other. The friction roller is connected to the rail for sliding. When the sightseeing train is running normally, the two sets of connecting rods are pressed against the inside of the rail, and the friction roller is pressed against the rail for sliding, thus maintaining the stable operation of the moving platform.

[0008] Preferably, the control platform has wheels installed inside, with the wheels located at the upper end of the rails. A rotating rod is installed between two sets of wheels, and a connecting rod is rotatably installed on the outer side of the wheels. A clamp and component are fixedly installed at the lower end of the connecting rod. The wheels travel stably on the rails. When the mobile platform moves and turns, the clamp and component keep the clamps and components on both sides in the anti-derailment bracket to prevent the platform from derailing and overturning when turning.

[0009] Preferably, the card and component include a connecting piece, one end of which is fixedly mounted with a connecting frame. Multiple sets of elastic elements are fixedly mounted inside the connecting frame. One end of each elastic element is provided with a friction ball. A blocking strip is fixedly mounted at the lower end of the anti-derailment bracket. The connecting pieces on both sides are blocked between the anti-derailment bracket and the rail by the blocking strip, thus restricting the movement and turning of the mobile platform. During normal travel, the mobile platform slides along the inside of the anti-derailment bracket via the friction ball. The locking mechanism between the connecting piece and the anti-derailment bracket restricts the mobile platform from turning and slightly tipping over. When the tipping angle is too large, the control platform receives a command and controls the hydraulic telescopic rod to move downwards, with both moving downwards simultaneously to compress and tighten the sightseeing train.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model proposes a sightseeing train anti-derailment fastening device. When the sightseeing train is in use, the moving platform moves along the rail. When one or both wheel treads detach from the rail surface, the control platform receives a command and controls the hydraulic telescopic rod to move downward, squeezing the two sets of connecting rods. The downward compression of the connecting rods creates a squeezing force on the rail, preventing the wheelset from detaching from the rail. When turning, the anti-derailment bracket prevents the train from tilting due to lateral derailment. This effectively prevents the anti-derailment bracket from detaching from the rail, ensuring the safety of passengers and equipment. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Combination Figure 1-3 A sightseeing train derailment prevention and fastening device includes a mobile platform 1, which includes a base 11. A control platform 12 is provided at the lower end of the base 11. A hydraulic telescopic rod 13 is fixedly installed at the lower end of the control platform 12. A connecting block 131 is fixedly installed at the drive end of the hydraulic telescopic rod 13. Two sets of connecting rods 14 are rotatably installed at the lower end of the connecting block 131. One end of the two sets of connecting rods 14 is rotatably connected. A U-shaped fixing strip 15 is rotatably installed on the outer side of the two sets of connecting rods 14. The upper end of the U-shaped fixing strip 15 is fixedly connected to the connecting block 131. A rail 21 is slidably installed at one end of each set of connecting rods 14. A rail is fixedly installed at the lower end of the rail 21. The fixed plate 2 and the two sets of rails 21 are each equipped with an anti-derailment bracket 22. When the sightseeing train is in use, the moving platform 1 moves along the rails 21. When one or both wheel treads detach from the rail surface, the control platform 12 receives the instruction and controls the hydraulic telescopic rod 13 to move downward, squeezing the two sets of connecting rods 14. The downward compression of the connecting rods 14 creates a squeezing force on the rails 21, preventing the wheelsets from detaching from the rails. When turning, the anti-derailment bracket 22 prevents the train from deviating from the rail surface in the left or right direction and causing it to overturn. This effectively prevents the anti-derailment bracket 22 from detaching from the rails 21, thus fully ensuring the safety of passengers and equipment.

[0022] Combination Figure 2-3 Each of the two sets of connecting rods 14 is equipped with a friction roller 141 at one end that is far apart from each other. The friction roller 141 slides and connects with the rail 21. When the sightseeing train is running normally, it slides by the two sets of connecting rods 14 close to the inside of the rail 21 and by the friction roller 141 in contact with the rail 21, thus maintaining the stable operation of the moving platform 1.

[0023] Combination Figure 2-4The control platform 12 has wheels 16 installed inside, which are located at the upper end of the rail 21. A rotating rod 161 is installed between the two sets of wheels 16. A connecting rod 162 is rotatably installed on the outer side of the wheels 16. A clip and component 17 are fixedly installed at the lower end of the connecting rod 162. The wheels 16 travel stably on the rail 21. When the mobile platform 1 moves and turns, the clip and component 17 keep the clips and components on both sides in the anti-derailment bracket 22 to prevent the platform from derailing and overturning when turning.

[0024] Combination Figure 4-6 The card and component 17 includes a connecting piece 171, with a connecting frame 172 fixedly installed at one end of the connecting piece 171. Multiple sets of elastic elements 173 are fixedly installed inside the connecting frame 172. A friction ball 174 is provided at one end of the elastic element 173. A blocking strip 221 is fixedly installed at the lower end of the anti-derailment bracket 22. The connecting pieces 171 on both sides are blocked between the anti-derailment bracket 22 and the rail 21 by the blocking strip 221, which restricts the movement and turning of the mobile platform 1. When the mobile platform 1 is moving and turning normally, it slides on the inside of the anti-derailment bracket 22 through the friction ball 174. The locking between the connecting piece 171 and the anti-derailment bracket 22 completes the restriction on the turning and slight overturning of the mobile platform 1 to a certain extent. When the overturning angle is too large, the control platform 12 receives the command and controls the hydraulic telescopic rod 13 to move downward. The two are squeezed simultaneously to tighten the sightseeing train.

[0025] Working principle: When the sightseeing train is running normally, the two sets of connecting rods 14 slide close to the inside of the rail 21 through the friction rollers 141, keeping the moving platform 1 stable. When the wheel treads detach from the rail surface, the control platform 12 controls the hydraulic telescopic rod 13 to move downward, squeezing the two sets of connecting rods 14 to form a squeezing force on the rail 21, preventing the wheelset from detaching from the rail. When turning, the wheels 16 travel on the rail 21, and the connecting piece 171 in the card and assembly 17 is blocked between the anti-derailment bracket 22 and the rail 21 by the blocking strip 221. The friction ball 174 slides and moves with the inside of the anti-derailment bracket 22, completing the restriction on the moving platform 1 when turning and slightly overturning. When the overturning angle is too large, the control platform 12 controls the hydraulic telescopic rod 13 to move downward, and the two squeeze synchronously to achieve tightness.
