Description

Technical Field

[0001] The utility model relates to the technical field of supporting facilities for roller coasters, in particular to a roller coaster climbing non-return protection device. Background Art

[0002] Roller coasters are a type of amusement equipment commonly found in amusement parks and parks. Their main structures include a car body, track, columns, lifting devices, and braking devices. The car body is lifted to the highest point of the track by the thrust of a mechanical lifting device, and then separated from the lifting device. The car body slides downward by gravity potential energy, rolls and turns along the designed track, and then returns to the platform. In order to prevent the car body from reversing during the lifting process and causing an accident, a non-return device is usually installed on the lifting track of the roller coaster to prevent the car body from reversing. Traditional non-return devices take up a large space, have a complex structure, high installation and maintenance costs, and limited practicality. Utility Model Content

[0003] The utility model aims to provide a roller coaster climbing non-return protection device to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A roller coaster climbing non-return protection device comprises a roller coaster body and a track, wherein the roller coaster body comprises a boarding platform and a slide assembly connected to each other, and the roller coaster body is slidably connected to the track through the slide assembly, a non-return pawl assembly is arranged on the slide assembly, a non-return rack and an auxiliary bar are arranged on the track along the traveling direction of the roller coaster body, and the non-return pawl assembly is located above the non-return rack and the auxiliary bar, the non-return pawl assembly comprises a pawl rotatably mounted on the slide assembly through a rotating shaft, the non-return end face of the pawl is in contact with the tooth face of the non-return rack, an auxiliary pawl is rotatably mounted on one side of the pawl, and a limit frame is arranged on one side of the auxiliary pawl, and the bottom end of the auxiliary pawl is in contact with the upper surface of the auxiliary bar.

[0006] As a further solution of the utility model: the slide assembly includes a chassis and a pulley block arranged on the chassis, and the anti-return claw assembly is arranged on one side of the chassis.

[0007] As a further solution of the utility model: the track includes a plurality of sleepers and rail posts installed on both sides of the sleepers, and the pulley block of the slide assembly is slidably connected to the rail posts of the track.

[0008] As a further solution of the utility model: a plurality of mounting seats are fixedly installed on both sides of the sleeper, and the mounting seats are fixedly connected to the non-return rack and the auxiliary strip through a bolt assembly.

[0009] As a further solution of the utility model: a limit plate is fixedly mounted on one side of the chassis at a position above the rotating end of the pawl through a mounting platform.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. When the roller coaster body is lifted upward, the auxiliary claw is limited by the position frame and is placed on the auxiliary bar. At this time, the pawl is separated from the check rack, which can prevent the pawl from colliding with the check rack and generating noise, thereby achieving the effect of eliminating noise;

[0012] 2. When the roller coaster body fails and reverses, the auxiliary claw rotates clockwise, and the ratchet pawl engages with the non-return rack, which can prevent the roller coaster body from going back and prevent accidents;

[0013] 3. By installing a limit plate on one side of the chassis above the rotating end of the pawl, the rotation of the pawl can be limited to prevent the pawl from flipping and shifting when the roller coaster body is in operation or reverses due to a malfunction, thereby affecting the anti-reverse effect.

The slide assembly 4 comprises a chassis 5 and a pulley block 6 arranged on the chassis 5, and a non-return claw assembly 7 is arranged on one side of the chassis 5.

[0022] The track 2 includes a plurality of sleepers 8 and rail posts 9 installed on both sides of the sleepers 8, and the pulley block 6 of the carriage assembly 4 is slidably connected to the rail posts 9 of the track 2. A non-return rack 10 and an auxiliary bar 11 are laid on the sleepers 8 along the traveling direction of the roller coaster body 1, and the non-return claw assembly 7 is located above the non-return rack 10 and the auxiliary bar 11. A plurality of mounting seats 12 are fixedly installed on both sides of the sleepers 8, and the mounting seats 12 are fixedly connected to the non-return rack 10 and the auxiliary bar 11 through bolt assemblies, and the non-return rack 10 and the auxiliary bar 11 can be installed and limited by the mounting seats 12.

[0023] The anti-return pawl assembly 7 includes a pawl 702 rotatably mounted on one side of the chassis 5 through a rotating shaft 701, the anti-return end face of the pawl 702 fits against the tooth surface of the anti-return rack 10, an auxiliary pawl 703 is rotatably mounted on one side of the pawl 702, and a limit frame 704 is provided on one side of the auxiliary pawl 703, through which the auxiliary pawl 703 can only rotate clockwise but not counterclockwise, and the bottom end of the auxiliary pawl 703 contacts the upper surface of the auxiliary bar 11. When the roller coaster body 1 is lifted upward, the auxiliary claw 703 is limited by the limited positioning frame 704 and stands on the auxiliary bar 11. At this time, the ratchet 702 is separated from the non-return rack 10, which can prevent the ratchet 702 from colliding with the non-return rack 10 and generating noise, thereby achieving the effect of eliminating noise.
