Description

Technical Field

[0001] This utility model relates to the field of amusement facility technology, specifically to a roller coaster drive wheel frame adjustment device. Background Technology

[0002] In the field of large-scale amusement rides, roller coaster-type track equipment has become an important attraction in theme parks due to its high-speed gliding and dynamic curves. Through a combination of track gradient differences, spiral curves, and dynamic acceleration, it provides riders with intense sensory stimulation experiences such as weightlessness and sprinting. However, the high speed and significant vibration of roller coasters during rides necessitate real-time self-adjustment of their drive wheels to prevent them from jamming or veering off the track, thus avoiding danger. For example, patent CN208065756U discloses a roller coaster drive wheel frame adjustment device. The device is driven by a motor to rotate the drive wheel, which in turn drives the driven wheel via a belt, thereby rotating the drive wheel coaxial with the driven wheel and enabling the movement of the gliding derrick. The device is equipped with a tension wheel, which allows it to quickly return to its original position after strong vibration and deformation. However, the drive wheel of this device is fixed in position on the frame and cannot adapt to track deformation and manufacturing tolerances. When the guide rail experiences local fluctuations due to thermal expansion and contraction, foundation settlement, or construction errors, gaps or excessive compression can easily occur between the drive wheel and the track, leading to decreased drive efficiency, abnormal wheel wear, and even equipment vibration during operation, affecting ride comfort and safety.

[0003] To address this issue, we have designed a wheel frame adjustment device for the gliding dragon drive wheel to solve the aforementioned problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figures 1-4 In this embodiment: a gliding dragon drive wheel frame adjustment device includes an adjustment structure, which is set at the bottom of the base plate 9. The adjustment structure includes a cylindrical tube 1, a slider 3, and a wheel frame 5. Two vertical cylindrical tubes 1 are arranged above the wheel frame 5. Both cylindrical tubes 1 are fixed to the bottom of the base plate 9. The inside of each cylindrical tube 1 is provided with a slider 3 that can slide up and down, and the bottom of the slider 3 is connected to a connecting post 4. The height of the inner cavity of the cylindrical tube 1 is less than the height of the connecting post 4. A frustum-shaped rubber block 2 is fixed to the top of the inner cavity of the cylindrical tube 1. The bottom of the cylindrical tube 1 has a through hole for the connecting post 4 to pass through. The bottom ends of the two connecting posts 4 are fixed to the top of the wheel frame 5. A spring 6 is fitted, with its two ends connected to the bottom of the cylindrical tube 1 and the top of the wheel frame 5, respectively. The spring 6 is always in a compressed state. A shaft is rotatably mounted on the wheel frame 5, and a drive wheel 7 and a driven sprocket 8 are mounted on the shaft. A motor 10 and a tensioning structure 13 are also mounted on the bottom of the base plate 9. A drive sprocket 11 is mounted on the output shaft of the motor 10. A chain 12 is provided between the drive sprocket 11 and the driven sprocket 8. The base plate 9 is fixedly installed on the bottom of the sliding dragon carriage 14. Multiple sets of traveling wheels 15 are also installed on the bottom of the sliding dragon carriage 14. The sliding dragon carriage 14 is slidably mounted on the sliding dragon guide rail 16 through the traveling wheels 15. The drive wheel 7 is in close contact with the sliding dragon guide rail 16.

[0021] The tensioning structure 13 includes a housing 131, a rotating shaft 132, a spring 133, a rotating rod 134, and a tensioning sprocket 135. The housing 131 is fixed to the bottom of the base plate 9. The rotating shaft 132 is rotatably mounted inside the housing 131 via a bearing. The spring 133 is sleeved on the rotating shaft 132. The inner end of the spring 133 is fixed to the rotating shaft 132, and the outer end of the spring 133 is fixed to the inner side wall of the housing 131. The spring 133 is always in a tightened state. One end of the rotating shaft 132 passes through the housing 131 and is mounted on the rotating rod 134. The tensioning sprocket 135 is rotatably mounted on the rotating rod 134 via a bearing. The tensioning sprocket 135 is located inside the chain 12 and meshes with the chain 12.

[0022] Example 1: The wheel frame adjustment device of this gliding dragon drive wheel achieves its function in the following way: The base plate 9 is fixed to the bottom of the first or last section of the gliding dragon carriage 14. Two cylindrical tubes 1 are vertically welded to the bottom sides of the base plate 9. The inner cavity of the tubes 1 and 2 are pre-installed with sliding blocks 3 that can slide up and down. The bottom of the sliding blocks 3 is rigidly connected to the wheel frame 5 through the connecting column 4. The outer periphery of the connecting column 4 is fitted with a compression spring 6. The two ends of the spring 6 abut against the bottom of the cylindrical tube 1 and the top of the wheel frame 5, respectively, so that the wheel frame 5 is always subjected to a downward elastic force. The wheel frame 5 is mounted with a drive shaft through a bearing. The drive wheel 7 and the driven sprocket 8 are mounted on the drive shaft. The drive wheel 7 is in contact with the surface of the gliding dragon guide rail 16. The bottom of the base plate 9 is also equipped with a motor 10. The drive sprocket 11 of the output shaft and the driven sprocket 8 are driven by a chain 12. When the motor 10 is powered on, the drive wheel 7 rotates, pushing the gliding dragon carriage 14 to move along the gliding dragon guide rail 16.

[0023] Example 2: To address the issue of chain 12 loosening due to vibration or thermal expansion and contraction, the device is equipped with a tensioning structure 13, which includes a housing 131, a rotating shaft 132, a spring 133, a rotating rod 134, and a tensioning sprocket 135. The housing 131 is welded to the bottom of the base plate 9. The rotating shaft 132 is mounted inside the housing via bearings. The spring 133 is sleeved around the outer circumference of the rotating shaft 132. The inner end of the spring 133 is fixed to the outer side of the rotating shaft 132, and the outer end is fixed to the inner wall of the housing 131. The upper part of the rotating shaft 132 is always subjected to a clockwise torque. The outer end of the rotating shaft 132 extends out of the housing 131 and is connected to the rotating rod 134. The end of the rotating rod 134 is equipped with a tension sprocket 135 through a bearing. The tension sprocket 135 is located inside the chain 12 and meshes with it. When the chain 12 is slack, the spring 133 drives the rotating shaft 132 to rotate, causing the rotating rod 134 to swing, causing the tension sprocket 135 to shift outward, automatically compensating for changes in the length of the chain 12 and maintaining transmission stability.

[0024] Example 3: The inner cavity height of the cylindrical tube 1 is designed to be less than the height of the connecting column 4. A frustum-shaped rubber block 2 is embedded at the top of the inner cavity of the cylindrical tube 1. When the drive wheel 7 encounters a protrusion or depression in the guide rail during its movement, the wheel frame 5 can move up and down. The spring 6 keeps the drive wheel 7 in close contact with the guide rail. Moreover, the spring 6 can absorb and reduce the impact of the drive wheel 7 on the uneven track. If the spring 6 is compressed to the limit position, the top of the slider 3 will contact the rubber block 2. The elastic deformation of the rubber block 2 absorbs the remaining impact force, thereby buffering the impact load between the drive wheel 7 and the guide rail and preventing hard collisions. At the same time, the frustum structure of the rubber block 2 can disperse stress and avoid local crushing.

[0025] Example 4: Based on Example 2, the spring 133 of the tensioning structure 13 is made of a high elastic coefficient material that can still provide stable torque output in an ambient temperature range of -20℃ to 60℃, such as stainless steel or alloy spring steel. When the chain 12 relaxes due to thermal expansion, the spring 133 drives the rotating rod 134 and the tensioning sprocket 135 to swing outward through the rotating shaft 132 to compensate for the relaxation. When the chain 12 tightens due to cold contraction, the rotating rod 134 and the tensioning sprocket 135 swing inward to avoid overloading the chain 12.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
