Description

Technical Field

[0001] This utility model relates to the field of cableway chairlift technology, and in particular to an automatic circulation mechanism for mining cableway chairlifts. Background Technology

[0002] Mining cableway chairlifts are essential equipment for personnel transportation in specific environments such as mines. They typically consist of the chairlift itself, suspension system, etc., and are suspended from a cableway to achieve rapid personnel transport. The design of mining cableway chairlifts needs to consider factors such as safety, comfort, and reliability. The automatic circulation mechanism of the mining cableway chairlift is a system designed to ensure the continuous operation of the chairlift. The automatic circulation mechanism typically includes a drive unit, a transmission unit, and a guide unit. The drive unit provides power to the chairlift, the transmission unit transmits power to the chairlift, and the guide unit ensures the chairlift follows the correct trajectory on the cableway.

[0003] In practical mining transportation scenarios, existing automatic circulation mechanisms for mining cableway chairlifts have some shortcomings. Regarding the power source, traditional automatic circulation mechanisms for mining cableway chairlifts typically use external motors. For example, in some mines, the automatic circulation of the mining cableway chairlift is achieved through a motor-driven transmission device. However, this approach has several problems. First, the external motor consumes a large amount of electrical energy, which increases operating costs in mines with tight energy supplies. Second, the external motor requires a complex control system to achieve speed regulation, start-stop, and other functions, increasing system complexity and maintenance costs. Moreover, in harsh mining environments, the motor is affected by dust, moisture, and other factors, reducing its reliability and lifespan. Therefore, this paper proposes an automatic circulation mechanism for mining cableway chairlifts to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic circulation mechanism for mine cableway chairlifts, which aims to improve the problems of existing cableway chairlift circulation mechanisms that use motors as the power source, are easily affected by the external environment, and consume a lot of energy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic circulating mechanism for a mining cableway chairlift, comprising a cableway and auxiliary components. A mounting frame is provided at the bottom of the cableway. A guide wheel one and a guide wheel two are rotatably connected to the inner side of the mounting frame. The auxiliary components are disposed inside the guide wheel two. A mounting shell is fixedly connected to the outer side of the mounting frame. A rotating component is disposed inside the mounting shell. The rotating component is used for the guide wheel two to rotate and circulate.

[0006] The rotary assembly includes a first cylindrical gear, which is rotatably connected inside the mounting housing. A spring is fixedly connected to the inner wall of the mounting housing. A rotating rod is fixedly connected to the outer side of the second guide wheel, and the second cylindrical gear is fixedly connected to the outer side of the rotating rod.

[0007] Furthermore, the second cylindrical gear is located inside the mounting housing, and the second cylindrical gear meshes with the first cylindrical gear.

[0008] Furthermore, one end of the rotating rod is rotatably connected to the inner wall of the mounting housing, and the edge end of the spring is fixedly connected to the outer side of the cylindrical gear.

[0009] Furthermore, the auxiliary component includes multiple rubber blocks, which are slidably connected inside the second guide wheel, and the second guide wheel is slidably connected to an insert rod.

[0010] Furthermore, one end of the insertion rod is fixedly connected to a pull ring, and the other end of the insertion rod is slidably connected to the outer side of a plurality of rubber blocks.

[0011] Furthermore, a slot is provided on the outer side of the insertion rod, and a locking block engages inside the slot.

[0012] Furthermore, the bottom of the mounting frame is rotatably connected to two sets of connecting plates, and one end of each of the two connecting plates is rotatably connected to a hanging chair plate.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, the guide wheel rolls along the outside of the cableway, and with the cooperation of multiple structures, the cylindrical gear rotates and compresses the spring to store energy. Then, the rubber block increases the friction between the guide wheel and the cableway. After that, the spring is released, and the power is transmitted to the guide wheel, causing it to rotate in the opposite direction. This drives the entire chairlift structure to move towards the starting point, achieving automatic circulation. This method is more energy-efficient than the traditional method of adding an external motor or other power source. Traditional power sources consume a lot of electrical energy and require complex control systems and maintenance. The method of storing and releasing energy using a spring not only saves energy but also has a simpler structure and is easier to assemble.

[0015] In this invention, a chairlift structure is constructed by setting up a single cableway in conjunction with guide wheels one and two. This reduces the number of cableways compared to traditional double or multiple cableways, thereby reducing the space occupancy rate in the mine and providing workers with a more spacious working area.

[0022] 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.

[0023] Reference Figures 1-4This utility model provides an embodiment of an automatic circulating mechanism for a mining cableway chairlift, comprising a cableway 1 and auxiliary components. The cableway 1, as the core of the entire automatic circulating mechanism, undertakes the important task of suspending and transporting the chairlift. The cableway 1 is typically made of high-strength steel wire rope or other durable materials, capable of withstanding significant weight and tension. A mounting frame 2 is provided at the bottom of the cableway 1, providing stable support and a mounting foundation for the entire mechanism. The inner side of the mounting frame 2 is rotatably connected to guide wheels 3 and 4, which roll on the cableway 1, guiding and supporting the chairlift. The auxiliary components are located inside the guide wheels 4 and include multiple rubber blocks 12. The rubber blocks 12 have good elasticity and wear resistance, enabling... To increase the friction between the guide wheel 2 4 and the cableway 1, rubber blocks 12 are slidably connected inside the guide wheel 2 4, allowing them to extend or retract as needed. An insert rod 13 is slidably connected inside the guide wheel 2 4, with a pull ring 14 fixedly connected to one end. The pull ring 14 is designed for easy operation by the operator. The other end of the insert rod 13 is slidably connected to the outer side of multiple rubber blocks 12. When the insert rod 13 is inserted into the guide wheel 2 4, it compresses the multiple rubber blocks 12, causing them to move outward, thereby increasing the friction between the guide wheel 2 4 and the cableway 1. A slot 15 is provided on the outer side of the insert rod 13, and a locking block 16 engages inside the slot 15. The locking block 16 prevents the insert rod 13 from accidentally dislodging, ensuring the rubber blocks 12 can be stably engaged. The rubber block 12 is kept in the extended position. A protrusion is provided at one end to prevent the rubber block 12 from falling out of the guide wheel 4. A mounting shell 7 is fixedly connected to the outer side of the mounting bracket 2. The mounting shell 7 provides installation space and protection for the rotating assembly. The rotating assembly is located inside the mounting shell 7 and is used for the rotational circulation of the guide wheel 4. The rotating assembly includes a cylindrical gear 8, which is rotatably connected inside the mounting shell 7. The cylindrical gear 8 can rotate freely within the mounting shell 7, realizing the transmission and conversion of power. A spring-loaded spring 9 is fixedly connected to the inner wall of the mounting shell 7. The spring-loaded spring 9 has the function of storing and releasing energy. A rotating rod 10 is fixedly connected to the outer side of the guide wheel 4, and the rotating rod 10 transmits the rotation of the guide wheel 4 to the cylindrical gear 11. A cylindrical gear 11 is fixedly connected to the outer side of the rotating rod 10. The cylindrical gear 11 is located inside the mounting shell 7 and meshes with a cylindrical gear 8. Power is transmitted through gear meshing. One end of the rotating rod 10 is rotatably connected to the inner wall of the mounting shell 7 to ensure stable rotation of the rotating rod 10. The edge end of the spring 9 is fixedly connected to the outer side of the cylindrical gear 8. When the guide wheel 4 drives the rotating rod 10 and the cylindrical gear 11 to rotate, the cylindrical gear 11 will drive the cylindrical gear 8 to rotate, thereby gradually compressing the spring 9 and storing energy. Two sets of connecting plates 5 are rotatably connected to the bottom of the mounting frame 2. The connecting plates 5 serve to connect the mounting frame 2 and the hanging chair plate 6. One end of the two connecting plates 5 is rotatably connected to the hanging chair plate 6.The hanging chair platform 6 is the section for staff seating, providing a comfortable and safe environment for them.

[0024] Specifically, firstly, staff members ride on chairlift 6 from the starting point to the end point. During this process, chairlift 6 is connected to mounting frame 2 via connecting plate 5. Guide wheels 3 and 4 on mounting frame 2 roll along the outside of cableway 1. The rolling of guide wheel 4 drives rotating rod 10 to rotate, and cylindrical gear 11 on rotating rod 10 rotates accordingly. Since cylindrical gear 11 meshes with cylindrical gear 8, cylindrical gear 11 drives cylindrical gear 8 to rotate. The rotation of cylindrical gear 8 causes the spring 9 to gradually compress, storing energy. During this period, guide wheels 3 and 4 roll along the outside of cableway 1, causing guide wheel 4 to drive rotating rod 10 to rotate, which in turn causes cylindrical gear 11 to drive cylindrical gear 8 to rotate, thus gradually compressing spring 9. Then, insert rod 13 is inserted into guide wheel 4 to compress multiple rubber blocks 12, which move outward, thereby increasing the compression of guide wheel 4. The friction between the cableway 1 and the insertion of the rod 13 need to be carefully performed to ensure that the rubber block 12 can extend evenly from the surface of the guide wheel 4, thus increasing the friction effect more stably. Releasing the power of the spring 9 can drive the cylindrical gear 8 to rotate in the opposite direction. In this way, in conjunction with the cylindrical gear 11 and the rotating rod 10, the power is transmitted to the guide wheel 4, causing the guide wheel 4 to rotate in the opposite direction. The reverse rotation of the guide wheel 4 will drive the entire chairlift structure to move towards the starting point, realizing automatic circulation. This method of using the spring 9 to store and release energy not only saves energy but also has a simple structure and high reliability.

[0025] Working principle: First, the staff will ride on the chairlift 6 and move from the starting point to the end point. During this time, guide wheel 1 3 and guide wheel 2 4 will roll along the outside of the cableway 1, which will cause guide wheel 2 4 to drive the rotating rod 10 to rotate, causing cylindrical gear 2 11 to drive cylindrical gear 1 8 to rotate. This will cause the spring 9 to gradually compress. Then, the insert rod 13 is inserted into the inside of guide wheel 2 4 to compress multiple rubber blocks 12 to move outward, thereby increasing the friction between guide wheel 2 4 and cableway 1. The power of the spring 9 is then released, which can drive cylindrical gear 1 8 to rotate in the opposite direction. In this way, in conjunction with cylindrical gear 2 11 and rotating rod 10, the power is transmitted to guide wheel 2 4, causing guide wheel 2 4 to rotate in the opposite direction. This allows the entire chairlift structure to move towards the starting point, thus achieving automatic circulation. Compared with the traditional method of adding external motors and other power sources, it saves a lot of energy.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
