Description
Technical Field
[0001] This utility model relates to the field of pulley technology, specifically a pulley with pulley auxiliary components. Background Technology
[0002] A pulley is a simple machine used to change the direction of a force or increase its distance. It typically consists of one or more pulleys connected to the load via ropes or chains. Pulleys can be classified as fixed pulleys and movable pulleys. In a fixed pulley, the axle is stationary, while in a movable pulley, the axle can move. Pulley systems can be used to lift heavy objects, change the direction of a force, or serve as part of a transmission system. Pulleys can also be classified as single-door pulleys, double-door pulleys, and multi-door pulleys. They play a significant role in lifting operations, mechanical transmission, and logistics transportation. Pulleys have a wide range of applications. For example, scenic spots often install single-door pulleys on a single cable connected to areas with elevation differences. After the safety ropes on tourists are connected to the hooks of the pulley, tourists use gravity to glide along the cable for recreational purposes.
[0003] The existing toboggan rides in scenic areas are not equipped with deceleration devices. Under the influence of gravity, the speed of tourists sliding along the cable will increase, posing a significant safety hazard and having a great psychological impact on tourists.
[0004] Therefore, those skilled in the art have provided a trolley with a pulley auxiliary component to solve the problems mentioned in the background art. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In this invention, a brake assembly is provided, including a brake cup, a friction ring, a rotating wheel, a movable cavity, a through hole, a sliding block, a sliding rod, brake pads, and a return spring. The brake cup is mounted on the side wall of a support plate and rotatably connected to a rotating shaft. The friction ring is mounted on the inner wall of the brake cup. The rotating wheel is mounted at the end of the rotating shaft and located inside the brake cup, allowing it to rotate synchronously with the shaft. The movable cavity is located on the side wall of the rotating wheel, and the through hole is located on the side wall of the rotating wheel and communicates with the movable cavity. The sliding block is slidably connected inside the movable cavity, and the sliding rod is fixedly connected to the sliding block and can move with the sliding block, driving the brake pads on the sliding rod to move. The return spring is sleeved on the sliding rod. When the pulley rotates too fast, under the action of centrifugal force, the centrifugal force of the brake pads can exceed the tension of the return spring. The brake pads can drive the sliding rod and sliding block to compress the return spring and move outward, allowing the brake pads to press against the friction ring. At the same time, as the rotating wheel rotates, the brake pads can rub against the friction ring, slowing down the pulley and ensuring the safety of tourists. Attached Figure Description

[0024] 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.
[0025] Please see Figures 1 to 8 In this embodiment of the utility model, a trolley with a pulley auxiliary component includes a pulley 1 and a rotating shaft 2. The pulley 1 is sleeved on the rotating shaft 2. Support plates 3 are provided opposite to each other on the rotating shaft 2. A fixing block 4 is provided between the two support plates 3. A rotating seat 5 is provided on the fixing block 4. A hook 6 is provided on the rotating seat 5. A braking component for decelerating the pulley 1 is provided between the rotating shaft 2 and the brake cup 7. The pulley 1 is sleeved on the rotating shaft 2. The two support plates 3 are rotatably connected to the rotating shaft 2 and located on both sides of the pulley 1. The rotating shaft 2 can fix the pulley 1 and drive the pulley 1 to rotate between the two support plates 3. The fixing block 4 is bolted between the two support plates 3, which can fix the two support plates 3, increase the structural strength between the two support plates 3, and thus improve the structural strength of the trolley, ensuring the safety of the tourists. The rotating seat 5 is rotatably connected to the fixing block 4. The hook 6 is fixedly installed at the end of the rotating seat 5 and can rotate with the rotating seat 5. The hook 6 is an existing type and has a locking function to ensure the safety of the tourists.
[0026] In one embodiment, the brake assembly specifically includes a brake cup 7 mounted on a support plate 3, the brake cup 7 being rotatably connected to a rotating shaft 2, a friction ring 8 on the brake cup 7, a rotating wheel 9 on the rotating shaft 2, a plurality of movable cavities 10 on the rotating wheel 9, and a through hole 11 on the rotating wheel 9. A sliding block 12 is provided inside each movable cavity 10, and a sliding rod 13 is provided on the sliding block 12. The sliding rod 13 is slidably connected to the through hole 11, and a brake pad 14 is provided on the sliding rod 13. The brake cup 7 is fixedly mounted on the side wall of the support plate 3 and rotatably connected to the rotating shaft 2, thus fixing the friction ring 8. The rotating wheel 9 is fixedly mounted at the end of the rotating shaft 2 and located inside the brake cup 7, allowing it to rotate synchronously with the rotating shaft 2. The plurality of movable cavities 10 are equidistantly spaced circumferentially inside the rotating wheel 9, and the through hole 11 is located on the side wall of the rotating wheel 9 and communicates with the movable cavities 10. The movable block 12 is slidably connected inside the movable cavity 10, allowing the sliding block 12 to move within the movable cavity 10. The sliding rod 13 is fixedly connected to the sliding block 12, allowing it to move with the sliding block 12 and drive the brake pad 14 to move. The sliding block 12 prevents the sliding rod 13 and the brake pad 14 from disengaging from the through hole 11. The brake pad 14 is fixedly installed at the end of the sliding rod 13 and located outside the rotating wheel 9. The friction ring 8 is fixedly installed on the inner wall of the brake cup 7. When the pulley 1 rotates too fast, under the action of centrifugal force, the centrifugal force of the brake pad 14 can be greater than the tension of the return spring 15. The brake pad 14 can drive the sliding rod 13 and the sliding block 12 to compress the return spring 15 and move outward, allowing the brake pad 14 to press against the friction ring 8. At the same time, as the rotating wheel 9 rotates, the brake pad 14 can rub against the friction ring 8, which can slow down the pulley 1 and ensure the safety of tourists.
[0027] The sliding rod 13 is provided with a return spring 15, which is sleeved on the sliding rod 13 and located inside the movable cavity 10. After the friction between the brake pad 14 and the friction ring 8 causes the rotational speed of the pulley 1 to decrease, the centrifugal force of the brake pad 14 is insufficient to resist the tension of the return spring 15. The return spring 15 drives the sliding rod 13 to retract into the movable cavity 10, which can cause the sliding rod 13 to separate the brake pad 14 from the friction ring 8, thereby stopping the deceleration of the pulley 1.
[0028] Based on the above embodiments, specifically, the sliding block 12 is provided with a protrusion 16, and the movable cavity 10 is provided with a sliding groove 17 corresponding to the protrusion 16. The protrusion 16 is integrally formed on the side wall of the sliding block 12, and the sliding groove 17 is opened on the inner wall of the movable cavity 10. The protrusion 16 and the sliding groove 17 are slidably connected, which can prevent the sliding block 12 from rotating when it moves in the movable cavity 10, prevent the brake pad 14 on the sliding rod 13 from rotating, and ensure the stability of the brake pad 14.
[0029] Furthermore, the brake pad 14 is arc-shaped and has multiple grooves 18. The arc-shaped brake pad 14 can make the brake pad 14 fit tightly with the friction ring 8. The multiple grooves 18 are formed on the outer wall of the brake pad 14, which can improve the friction between the brake pad 14 and the friction ring 8 and improve the braking performance.
[0030] In one embodiment, specifically, the friction ring 8 is provided with a plurality of inclined grooves 19, which are formed on the inner wall of the friction ring 8, thereby further improving the friction between the friction ring 8 and the brake pad 14 and further improving the deceleration effect on the pulley 1.
[0031] Furthermore, the brake cup 7 is provided with a plug 20, which is screwed onto the inner wall of the brake cup 7. This ensures the cleanliness of the inside of the brake cup 7 and prevents the brake components from malfunctioning due to foreign objects entering.
[0032] In use, first, loosen the bolts and remove the fixing block 4. Then, place the pulley 1 on the cable. Next, place the fixing block 4 between the two support plates 3 and tighten the bolts to secure it. At this point, the trolley is fixed to the cable. Then, hang the safety rope on the tourist's body on the hook 6. As the tourist slides along the cable with the trolley, the tourist's sliding speed increases due to the downward inclination of the cable. At the same time, the rotation speed of the pulley 1 also increases. The pulley 1 drives the rotating wheel 9 on the rotating shaft 2 to rotate faster and faster. When the rotation speed of the rotating wheel 9 reaches a certain speed, the centrifugal force of the brake pad 14 is greater than the tension of the return spring 15. Under the action of centrifugal force, the brake pad 14 drives the sliding rod 13 and the sliding block 12 along the movable cavity 10. As the vehicle moves outward, the centrifugal force increases, causing the brake pad 14 to come into contact with and press against the friction ring 8. Since the brake pad 14 rotates with the rotating wheel 9, and the rotating wheel 9 rotates with the pulley 1 on the rotating shaft 2, the brake pad 14 and the friction ring 8 rub against each other. Subsequently, the brake pad 14 drives the rotating wheel 9 to decelerate, and the rotating wheel 9 drives the pulley 1 on the rotating shaft 2 to gradually decelerate. When the rotational speed of the pulley 1 decreases, the centrifugal force of the brake pad 14 is insufficient to resist the tension of the return spring 15. The return spring 15 pushes the sliding block 12 to retract into the movable cavity 10. At the same time, the sliding block 12 drives the brake pad 14 on the sliding rod 13 to retract. Subsequently, the brake pad 14 separates from the friction ring 8. At this point, the sliding speed of the tourist is reduced to a safe range.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
