Description

Technical Field

[0001] The invention relates to the field of Ferris wheel drive control, and in particular to a Ferris wheel drive preload rapid control device and method thereof. Background Art

[0002] The Ferris wheel is a large-scale rotating wheel-shaped mechanical building facility, with cabins for passengers hanging on the edge of the wheel. Passengers sit on the Ferris wheel and slowly rotate upwards, and can overlook the surrounding scenery from a high altitude. The most common Ferris wheel is generally found in amusement parks (or theme parks) and garden fairs. As a kind of amusement park motor game, it is collectively called the "three treasures of the park" together with roller coasters and carousels. However, the Ferris wheel often exists alone in other occasions, usually used as an active observation deck. The working principle of the Ferris wheel is to use an electric motor to reduce speed through a reducer, convert high-speed and low-torque into high-torque and low-speed mechanical power, and transmit it to the wheel through an intermediate mechanism that is generally both elastic and strong, such as tires, so that it rotates at a low speed.

[0003] Currently, existing Ferris wheels basically use multiple sets of wheel discs clamped on both sides of the track, and are driven by motors to rotate on the outside of the track. In order to enable the wheel discs to clamp the track and maintain stability, balancing cylinders are usually used to tighten the multiple sets of wheel discs, and the balancing cylinders also start the braking effect. However, in an emergency, the multiple sets of wheel discs cannot be pre-tightened quickly, which affects the efficiency and safety of use. Summary of the invention

In order to enable the wheel discs to clamp the track and maintain stability, a balancing cylinder is usually used to tighten the multiple sets of wheel discs, and the balancing cylinder also starts the braking effect, but in an emergency, the multiple sets of wheel discs cannot be quickly pre-tightened, thereby affecting the use efficiency and safety.

[0012] Preferably, the support spring is sleeved on the outer wall of the support rod, the support rod passes through the bottom end of the support tube and is connected with an adjusting nut, and the adjusting nut is rotatably connected to the support rod through an internal thread.

[0013] Preferably, the method comprises the following steps:

[0014] Step 1: Start multiple motors, the output ends of the multiple motors drive the wheels to rotate, and the multiple wheels are attached to the top and bottom of the track, so that the overall mounting frame is driven to move through the wheels;

[0015] Step 2: When adjusting the tightness, turn the adjusting nut to change the distance that the support rod extends below the support tube, thereby changing the outer length of the support rod, changing the squeezing of the support spring, thereby changing the pulling force of the support tube on the upper box and the lower box, thereby changing the squeezing of the multiple sets of wheel discs on the track, thereby changing the friction between the wheel discs and the track;

[0027] In the present invention, the balancing cylinder 12 can be fixed by the supporting cylinder 16, so that the balancing cylinder 12 and the supporting cylinder 16 fix the upper box body 6 and the lower box body 7, so that the upper box body 6 and the lower box body 7 will not deviate during loading and operation.

[0028] Please refer to Figure 2 A balancing rod 15 is provided inside the balancing cylinder 12. The balancing rod 15 passes through the bottom end of the balancing cylinder 12 and is rotatably connected to the top end of the support rod 17.

[0032] The upper box 6 and the lower box 7 can be conveniently rotated by the self-lubricating bearing 5, so as to change the spacing between the multiple groups of wheel discs 20, change the friction between the wheel discs 20 and the track 4, and thus change the driving output of the Ferris wheel.

[0033] Please refer to Figure 5 A motor 23 is installed at one end of the upper box body 6, and the output end of the motor 23 passes through the upper box body 6 and extends to the interior of the upper box body 6 and is connected to a lubrication cavity 22. A bearing 21 is provided inside the lubrication cavity 22.

[0037] Please refer to Figure 5 , including the following steps:

[0038] Step 1: Start the multiple motors 23, the output ends of the multiple motors 23 drive the wheels 20 to rotate, and the multiple wheels 20 are attached to the top and bottom of the track 4, so that the overall mounting frame 1 is driven to move through the wheels 20;

[0039] Step 2: When adjusting the tightness, turn the adjusting nut 18 to change the distance that the support rod 17 extends below the support tube 16, thereby changing the outer length of the support rod 17, changing the squeezing of the support spring 19, thereby changing the pulling force of the support tube 16 on the upper box 6 and the lower box 7, thereby changing the squeezing of the multiple sets of wheel discs 20 on the track 4, thereby changing the friction between the wheel discs 20 and the track 4;

[0040] Step three: When the device needs to be urgently and quickly pre-tightened, rotate the pull plate 11 so that the pull plate 11 rotates around the second pin shaft 27. The pull plate 11 drives the first pin shaft 10 to rotate around the second pin shaft 27, forcing the height position of the first pin shaft 10 to change. The first pin shaft 10 drives the outer connected mounting sleeve plate 9 to change position, thereby changing the pulling force on the balance spring 14 in the balance bar 15, temporarily changing the pulling force of the balance bar 15 on the upper box body 6 and the lower box body 7, thereby changing the squeezing of the multiple sets of wheel discs 20 on the track 4, thereby changing the friction between the wheel discs 20 and the track 4.
