Technical Field

[0001] This utility model relates to the field of amusement facility technology, specifically a double-track trolley. Background Technology

[0002] Amusement facilities refer to vehicles used for commercial purposes to carry tourists for recreation. With the development of science and the progress of society, modern amusement machines and facilities make full use of advanced technologies such as mechanics, electricity, light, sound, water, and force, integrating knowledge, fun, science, and thrills. They are widely loved by teenagers and children. Among amusement facilities are roller coasters, which are a popular recreational facility that has emerged in recent years. They are simple to construct, require little space, and are suitable for construction in scenic areas and farms, making them very popular. Monorail roller coasters are generally built on sloping hillsides and other terrains, using the terrain to convert potential energy at high altitudes into kinetic energy to obtain the downward driving force of the roller coaster.

Driven by the motor gearbox assembly, the gear disc rotates, pushing the frame to move. The guide wheel on the guide frame contacts the guide rod, guiding the entire frame. Simultaneously, the front wheel, due to the linkage rod, rotates synchronously with the turn to adapt to the turn. When stationary, the spring pulls the slider, which slides backward within the arc-shaped pull plate. Pushing the handle to the right moves the pull rod, and the pressure plate is pressed down under the action of the connecting rod until a long brake is applied. When the car block contacts the guide rod, the car cannot move. By pushing the handle, the pressure plate moves upward, and the long brake block moves away from the guide rod, allowing the device to slide normally. When braking is needed, by pulling the handle, the long brake block contacts the guide rod, braking the entire device. The speed sensor can detect the speed of the device. If the speed exceeds a certain level, the speed sensor detects overspeed, the disc brake assembly is activated, locking the brake disc and braking the entire device. Through the above structure, the device can not only move smoothly on the track, but also has good braking performance and intelligent braking, greatly improving the safety of the trolley.

[0035] Several guide rail support frames 41 are movably mounted on the lower wall of the frame 1. One rail 42 is fixedly mounted on one end of the guide rail support frame 41, and the other rail 42 is fixedly mounted on the other end of the guide rail support frame 41.

[0036] As a preferred option, the sliding contact line 28 is located on the guide rail support frame 41.

[0037] As a preferred option, the toothed disc 6 further engages with the rack 44.

[0038] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0039] Example: According to the instruction manual attached Figure 1-3It can be seen that, firstly, the guide rail support frame 41 supports the rail 42 and the guide rod 43. The front wheel 22 and the rear wheel 32 contact the rail 42, supporting the frame 1 so that the device can slide on the rail 42. By connecting the power supply to the sliding contact line 28 and the sliding contact between the current collector 27 and the sliding contact line 28, the power supply is connected to the frame 1. The motor gearbox assembly 5 drives the gear plate 6 to rotate. After the gear plate 6 meshes with the rack 44, it pushes the frame 1 to move. During the movement, the guide wheel 25 on the guide frame 24 contacts the guide rod 43 to guide the frame 1 as a whole. At the same time, the front wheel 22 can rotate synchronously with the turn due to the action of the linkage rod to adapt to the turn. The brake block 26 limits the movement to prevent the frame 1 from leaving the rail 42 and assists in braking, so that it can use the curved rail 42. When there is no one on the vehicle, the handle 31 is in a state of no force. The spring 311 pulls the slider 310. 310 slides within the arc-shaped pull plate 39, and the handle 31 pushes the pull rod 35 to the right. The pressure plate 37 is pressed down by the connecting rod 36 until the long brake block 38 contacts the guide rod 43. At this point, the vehicle cannot move. When the driver gets on the vehicle, he pushes the handle 31, and the pressure plate 37 moves upward. The long brake block 38 moves away from the guide rod 43, and the device slides normally. It can be driven forward by the motor gearbox assembly 5. When braking is needed, the handle 31 is pulled, and the long brake block 38 contacts the guide rod 43, braking the entire device. The speed of the device can be detected by the speed sensor 312. If the driver fails to brake in time and the speed exceeds a certain level, the speed sensor 312 detects overspeed, and the disc brake assembly 34 is activated, locking the brake disc 33 and braking the entire device. Through the above structure, the device can not only move smoothly on the track 42, but also has good braking performance and can brake intelligently.
