Description

Technical Field

[0001] This utility model belongs to the field of cableway transportation technology, specifically relating to a transmission wheel for cableway transportation. Background Technology

[0002] In modern transportation systems, cableways, with their unique advantages, are widely used in mountainous areas, scenic spots, and mining material transport. Whether tourists are traveling to admire magnificent scenery from rugged peaks or mining companies are efficiently transporting mined ore out of the mountains, cableways play an irreplaceable role. As a key component of the cableway system, the performance of the drive wheels directly affects the stable operation and safety of the entire system.

[0003] Traditional cableway drive wheels typically have rigid grooves that are in direct contact with the steel wire rope. During cableway transport, the tension in the steel wire rope is constantly changing due to a variety of complex factors. Taking a mountain scenic area cableway as an example, the tension of the steel wire rope will fluctuate significantly when the number of passengers in the gondola varies, or when operating under different terrain conditions such as climbing or descending slopes. In mining material transport cableways, differences in the weight of the transported materials and the undulations of the transport route will also lead to unstable tension in the steel wire rope.

[0004] When a wire rope is subjected to high tension, the rigid groove cannot effectively buffer the stress, resulting in strong rigid compression. This compression not only exacerbates surface wear, leading to wire breakage and strand loosening, but also damages the internal structure, reducing its overall strength and service life. According to statistics, wire rope wear caused by traditional drive wheels has shortened the average replacement cycle by 30%-50%, significantly increasing maintenance costs and safety risks for cableway operations.

[0005] Furthermore, the friction between the rigid rope groove and the wire rope is difficult to automatically adjust according to tension changes. When the tension is low, the friction between the two is insufficient, which can easily lead to wire rope slippage, resulting in reduced transmission efficiency and even accidents such as hoisting stoppage and material conveying interruption. When the tension is high, the excessive friction will further aggravate the wear of the wire rope and drive wheel, creating a vicious cycle.

[0006] Traditional drive wheels also have significant drawbacks in the repair of worn rope grooves. Once the rope grooves become worn and damaged due to long-term use, the entire drive wheel often needs to be replaced. This not only involves complex disassembly and installation work, consuming a large amount of manpower, resources, and time, but also leads to prolonged cableway shutdowns, affecting normal operations. For example, replacing a large cableway drive wheel typically requires specialized technicians to spend 2-3 days, during which time the cableway cannot operate, resulting in substantial economic losses.

[0007] To address this, we propose a drive wheel for cableway transportation. This device not only ensures good contact and friction between the wire rope and the drive wheel, guaranteeing the stability and reliability of cableway transportation, but also allows for the replacement of only the entire elastic support assembly when the rope groove wears out due to prolonged use, eliminating the need to replace the entire drive wheel and thus extending its service life. Utility Model Content

[0008] The purpose of this invention is to provide a transmission wheel for cableway transportation. This device not only ensures that the wire rope and the transmission wheel always maintain good contact and friction, ensuring the stability and reliability of cableway transportation, but also, when the rope groove is worn and damaged due to prolonged use, only the entire elastic support assembly needs to be replaced, without replacing the entire transmission wheel body, thus improving its service life.

[0009] The specific technical solution adopted by this utility model is as follows:

[0010] A transmission wheel for cableway transportation includes a transmission wheel body, on which a rope groove is formed, and multiple elastic support components are installed on the inner wall of the rope groove;

[0011] Each of the elastic support components includes a mounting rod installed on the inner wall of the rope groove. An arc-shaped hollow shell is provided on one side of the mounting rod. A spring is provided inside the arc-shaped hollow shell. A movable disc is provided on one side of the spring. A movable rod is provided on the movable disc. The end of the movable rod away from the movable disc passes through the arc-shaped hollow shell and is equipped with a floating sliding block. A plurality of floating sliding blocks are arranged along the inner wall of the rope groove.

[0012] Furthermore, the transmission wheel includes a first connecting disc, a second connecting disc, and a third connecting disc. The first connecting disc and the second connecting disc have the same diameter. The third connecting disc is disposed between the first connecting disc and the second connecting disc. The diameter of the third connecting disc is smaller than the diameters of the first connecting disc and the second connecting disc. Two sets of first threaded holes and one set of second threaded holes are arrayed on the first connecting disc, the second connecting disc, and the third connecting disc. A first fixing bolt is disposed inside the first threaded hole, and the first connecting disc, the second connecting disc, and the third connecting disc are connected by the first fixing bolt.

[0013] Furthermore, the first connecting plate and the second connecting plate are composed of multiple sector plates, each of which is mounted on the third connecting plate by the first fixing bolt.

[0014] Furthermore, the third connecting plate has an installation hole on its outer side for inserting the mounting rod, and the mounting rod has a third threaded hole, with a second fixing bolt installed inside the third threaded hole and the second threaded hole.

[0015] Furthermore, each of the floating sliding blocks corresponds to one of the sector plates.

[0016] Furthermore, the floating sliding block is provided with anti-slip texture.

[0017] Furthermore, weight-reduction holes are provided on the first connecting plate, the second connecting plate, and the third connecting plate.

[0018] The technical effects achieved by this utility model are as follows:

The adaptive support structure composed of multiple floating sliding blocks can automatically adjust the contact pressure with the wire rope according to the stress of the wire rope, maintain a stable friction force, effectively prevent the wire rope from slipping, reduce the jumping and vibration of the wire rope, and improve the transmission stability and operational safety during cableway transportation.

[0020] 2. When the rope groove is worn and damaged due to prolonged use, only the entire elastic support assembly needs to be replaced, without replacing the entire transmission wheel, thus extending its service life. Attached Figure Description

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] like Figures 1-4 As shown, a transmission wheel for cableway transportation includes a transmission wheel body 1, a rope groove 2 is provided on the transmission wheel body 1, and a plurality of elastic support components are installed on the inner wall of the rope groove 2.

[0029] Each elastic support assembly includes a mounting rod 3 installed on the inner wall of the rope groove 2. An arc-shaped hollow shell 4 is provided on one side of the mounting rod 3. A spring 5 is provided inside the arc-shaped hollow shell 4. A movable disc 6 is provided on one side of the spring 5. A movable rod 7 is provided on the movable disc 6. The end of the movable rod 7 away from the movable disc 6 passes through the arc-shaped hollow shell 4 and is equipped with a floating sliding block 8. Multiple floating sliding blocks 8 are arranged along the inner wall of the rope groove 2 to form a support structure that adapts to the outer contour of the wire rope.

[0030] The transmission wheel 1 includes a first connecting disc 9, a second connecting disc 10, and a third connecting disc 11. The first connecting disc 9 and the second connecting disc 10 have the same diameter. The third connecting disc 11 is disposed between the first connecting disc 9 and the second connecting disc 10. The diameter of the third connecting disc 11 is smaller than the diameter of the first connecting disc 9 and the second connecting disc 10. The first connecting disc 9, the second connecting disc 10, and the third connecting disc 11 are provided with two sets of first threaded holes 12 and one set of second threaded holes 13. The first threaded holes 12 are provided with first fixing bolts 14, which connect the first connecting disc 9, the second connecting disc 10, and the third connecting disc 11.

[0031] Meanwhile, the first connecting plate 9 and the second connecting plate 10 are composed of multiple sector plates 15. Each sector plate 15 is mounted on the third connecting plate 11 by the first fixing bolt 14. This arrangement allows the entire sector plate 15 to be replaced only when the first connecting plate 9 and the second connecting plate 10 are worn or damaged, without having to replace the entire transmission wheel 1, thus improving their service life.

[0032] The third connecting plate 11 has an installation hole 16 on its outer side for inserting the mounting rod 3. The mounting rod 3 has a third threaded hole 17. The third threaded hole 17 and the second threaded hole 13 are provided with a second fixing bolt 18. This arrangement facilitates the installation and disassembly of the floating sliding block 8.

[0033] The third threaded hole 17 matches the second threaded hole 13, which facilitates the entry and removal of the second fixing bolt 18.

[0034] Spring 5 is made of high fatigue life chromium vanadium spring steel and adopts a variable diameter helical structure design. It provides flexible buffering force in the initial stage of compression, and gradually increases stiffness as the compression increases, forming non-linear buffering characteristics. The two ends of spring 5 are fixed to the housing and movable plate 6 by welding and snap-fitting, respectively.

[0035] It should be noted that the transmission wheel 1 is driven by an external motor, which is existing technology and will not be elaborated on further here.

[0036] The floating sliding block 8 is provided with anti-slip texture, which further increases the friction between it and the wire rope, preventing the wire rope from slipping during transmission.

[0037] The first connecting plate 9, the second connecting plate 10, and the third connecting plate 11 are all provided with weight reduction holes (not shown in the figure). The weight reduction holes can reduce the weight and improve the power output.

[0038] Each of the floating sliding blocks 8 corresponds to a sector plate 15, which enables modularity and facilitates subsequent replacement.

[0039] The working principle of this invention is as follows: When the cableway system is running, the wire rope is pulled and moved within the rope groove 2 of the drive wheel. During cableway transportation, the tension on the wire rope is not constant and fluctuates due to factors such as changes in load and terrain undulations. When the wire rope is under significant tension, it exerts considerable pressure on the floating sliding block 8 on the inner wall of the rope groove 2. At this time, after the floating sliding block 8 is subjected to pressure, the force is transmitted to the movable disc 6 through the movable rod 7. Under the pressure, the movable disc 6 compresses the spring 5, causing the floating sliding block 8 to retract into the arc-shaped hollow shell 4. The spring 5 stores elastic potential energy. This retraction action can effectively buffer the instantaneous large tension on the wire rope, avoiding wear and deformation of the wire rope due to rigid compression. When the tension on the wire rope decreases, the spring 5 releases the stored elastic potential energy, pushing the movable disc 6 to reset, which in turn drives the movable rod 7 and the floating sliding block 8 to extend outward, allowing the floating sliding block 8 to re-fit tightly against the surface of the wire rope. This ensures that the wire rope and the drive wheel always maintain good contact and friction, ensuring the stability and reliability of the cableway transportation. At the same time, when the rope groove 2 is worn and damaged due to prolonged use, only the entire elastic support assembly needs to be replaced, without replacing the entire drive wheel 1, thus extending its service life.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
