Description

Technical Field

[0001] The invention relates to the technical field of winch equipment, in particular to a main rope winch device of a cableway. Background Art

[0002] Cable winches are sometimes subject to high temperature loads due to the high power density they contain, which are reflected on the one hand in the drive of the cable winch (e.g. hydraulic motor or electric motor) and in the transmission mechanism usually connected in between. On the other hand, however, the temperature load of the cable to be wound also plays a role, especially when using high-strength fiber cables or plastic cables, since their limit temperatures are significantly lower than those of steel cables and the influence of the temperature load on the service life of the cable must be taken into account. In principle, however, it is also important in the case of steel cables to avoid excessive temperature loads or at least to take them into account, since this can lead to lubricant loss and excessive grease leakage from the cable and possibly increased wear.

[0003] At present, in some mountain cableways, the cables are always in operation for sightseeing transportation or material transportation, and the traditional technology is to use a driving mechanism to drive the winch to move, driving the wheel on the cable to operate, so as to realize the loop circulation. However, as the cable runs day and night, first of all, when in use, the cable will continuously rotate on the winch, and a large part of it is also driven by friction. As the rotation time increases, the temperature borne by the winch will be very large, affecting the stability of the cable during transportation. Because the higher the temperature, the thermal expansion and contraction of the cable will cause the surface of the cable to soften to a certain extent, and will drive the winch to wear. Therefore, a cableway main cable winch device is proposed to solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 8 A cableway main cable winch device comprises a frame 1, a driving module 2 is arranged on the frame 1, a winch module 5 is arranged on the frame 1, the driving module 2 drives the winch module 5 to rotate to drive the cable to be transported, and two transverse plates 8 are arranged on the frame 1; In this embodiment, the winch module 5 includes a winch 501, a self-lubricating device 502 and a cooling device. When the driving module 2 drives the winch 501 to move, it uses the rotation of the winch 501 to drive the self-lubricating device 502 to self-lubricate the cable on the winch 501, and synchronously drives the cooling device to cool the cable.

[0020] Furthermore, the driving module 2 includes a driving motor 201, the output end of the driving motor 201 is connected to a driving wheel 202, the surface of the driving wheel 202 is meshed with a transmission wheel 203, and the transmission wheel 203 is connected to the shaft rod inside the frame 1 through a planetary gear set 204, and the shaft rod is connected to the winch module 5. The rotation of the driving motor 201 drives the rotation of the planetary gear set 204 by utilizing the meshing of the gears, and when the planetary gear set 204 rotates, it will drive the shaft rod inside the frame 1 to rotate, providing power for the rotation of the winch 501, and the planetary gear set 204 is set to increase the torque of the shaft rod rotation, and the planetary gear also plays a great role in the torque transmission of power. Since the characteristics of the motor such as speed and torque are very different from the road driving requirements, the power of the motor should be appropriately distributed to the driving wheel, and the above characteristics of the planetary gear can be used for conversion.

[0021] Furthermore, a power shaft 506 is fixedly connected to the axis of the winch 501, and the top of the power shaft 506 is connected to the shaft rod inside the frame 1, and a full circle of grooves 5011 are provided on the surface of the winch 501. The rotation of the shaft rod will drive the rotation of the power shaft 506, and the power shaft 506 is connected to the winch 501, and the winch 501 will rotate at this time, and the main rope on the surface of the winch 501 will rotate, and then the auxiliary rope above will be driven through the connecting piece for transmission, and the main rope is used to transmit power. The friction of the cable on the winch can be increased by the provided grooves 5011, so that the cable is more stable during the transmission process, and when some emergency braking occurs, the grooves 5011 on its surface can provide a certain degree of friction for the cable to perform emergency braking.

[0022] In addition, the self-lubricating device 502 includes a sliding block 5021, a sliding rod 5022 is connected to the bottom of the sliding block 5021, a linkage plate 5024 is connected to the sliding rod 5022, an oil collecting tank 5025 is connected to the linkage plate 5024, an oil chamber 510 is provided inside the capstan 501, a plurality of oil holes 5026 are provided on the entire circle of the capstan 501, lubricating oil is injected into the oil chamber 510, an extrusion spring 5023 is connected to the bottom of the sliding rod 5022, and one end of the extrusion spring 5023 is fixedly connected to the bottom of the capstan 501. When the equipment is running for a long time, the cable itself and the capstan 501 are connected by friction, so high temperature will definitely be generated. After long-term operation, the surface of the cable will soften. The softened cable will collide with collision objects during transportation, which will cause marks on the surface, resulting in a reduction in its service life. Therefore, a self-lubricating device 502 is provided. Every time the winch 501 rotates one circle, the two sliding blocks 5021 will be driven to form abutment contact with the cross plate 8, and then the inclined surface will be used to slide in contact with the cross plate 8, thereby controlling the sliding blocks 5021 to move downward synchronously, and then the linkage plate 5024 is driven to move downward through the connection of the slide rod 5022, and then the linkage plate 5024 drives the oil collecting tank 5025 to move downward, and after the oil collecting tank 5025 moves downward, a part of the lubricating oil will be scooped out and placed inside the oil collecting tank 5025, and then the "scooping out" will make the lubricating oil flow to the position of the oil hole 5026, and then the cable will be automatically lubricated.

[0023] In addition, the sliding block 5021 is provided with an inclined surface, and the axis of the linkage plate 5024 is slidably connected to the inner cylinder of the winch 501. When the sliding block 5021 rotates, it contacts and abuts against the horizontal plate 8, thereby driving the linkage plate 5024 on the sliding rod 5022 to move up and down, and automatically transfer the lubricating liquid in the oil cavity to the oil hole 5026, so as to lubricate and cool the cable. When the sliding block 5021 is separated from the horizontal plate 8, the compression spring 5023 is retracted and reset, and the sliding rod 5022 is controlled to move upward, thereby driving the oil collecting groove 5025 on the linkage plate 5024 to move upward and align with the oil hole 5026. At this time, the internal oil of the oil collecting groove 5025 will enter the outer surface of the winch 501 and the surface of the cable along the multiple oil holes 5026, and lubricate the cable while also lubricating the winch 501. Because of the immersion of the oil, a certain degree of cooling effect can also be provided.

[0024] It is worth noting that a collecting groove 5027 is provided on the capstan 501. The collecting groove 5027 is used to receive excess lubricating oil and return it to the inside of the oil chamber 510 through the notch. The height of the collecting groove 5027 is higher than the bottom height of the oil chamber 510. The remaining lubricating liquid can be collected by the provided collecting groove 5027, and then return it to the inside of the oil chamber 510 from the internal opening position of the collecting groove 5027 for recycling and collection. Since the height of the collecting groove 5027 is higher than the height of the oil chamber 510, the oil will flow downward at this time and enter the inside of the oil chamber 510 for reflux utilization.

[0025] It is worth noting that the cooling device includes a gear sleeve 503, which is fixedly connected to a power shaft 506, and the inner wall of the gear sleeve 503 is meshed with a plurality of central gears 504 through teeth, and the central gear 504 is connected with blades 505, and the axis of the central gear 504 is connected with a cover 507 through a shaft, and an air inlet groove 508 and an air cavity 509 are provided in the cover 507, and the air cavity 509 is communicated with the internal oil cavity 510 of the capstan 501, and the cover 507 is fixed on the frame 1. An air extraction hole 511 is provided at the bottom of the capstan 501, and the air extraction hole 511 is communicated with the air cavity 509. When the power shaft 506 rotates, it will drive the gear sleeve 503 fixedly connected thereto to rotate, and the gear sleeve 503 is provided with teeth inside, and the meshing of the teeth drives the multiple center gears 504 to rotate. Therefore, at this time, the center gear 504 will drive the blades 505 to rotate, and the blades 505 will draw in external air from the position of the air extraction hole 511, enter the internal cavity of the gear sleeve 503, and then be discharged to the inside of the air cavity 509 through the air inlet groove 508, and then the air cavity 509 is connected with the internal oil cavity 510 of the winch 501, so the airflow will also be discharged from the multiple oil holes 5026 at this time. After being discharged, the cable is cooled and the winch 501 is cooled. Moreover, the airflow directly acts on the inside of the oil cavity 510, so it can also achieve the cooling of the oil, thereby ensuring the stability of each oil circulation lubrication process.

[0026] In addition, a hanger 3 is fixedly mounted on the frame 1, a wheel frame 4 is connected to the frame 1 through a plate 7, a load-bearing wheel 6 is mounted on the hanger 3, and a plurality of pulleys are rotatably connected to the wheel frame 4. The load-bearing wheels 6 can provide a certain support effect on the load-bearing of the main cable and the auxiliary cable, thereby improving the running stability of the cable. The plurality of pulleys are provided to make the auxiliary cable slide smoothly and reduce the friction of the auxiliary cable.

[0027] The working principle is that the operator first needs to control the driving motor 201 in the driving module 2 to rotate, and then drive the planetary gear set 204 to rotate through the meshing of the gears. When the planetary gear set 204 rotates, it will drive the shaft inside the frame 1 to rotate, providing power for the rotation of the winch 501. The planetary gear set 204 is set to increase the torque of the shaft rotation. In the prior art, most of the rotation of the winch 501 is driven by the rotation of the planetary gears. After that, the rotation of the shaft will drive the rotation of the power shaft 506, and the power shaft 506 is connected to the winch 501. At this time, the winch 501 will rotate, and the main rope on the surface of the winch 501 will rotate, and then the auxiliary rope above will be driven by the connecting piece for transmission, and the main rope is used to transmit power. Because when the entire equipment is running, it needs to work for a long time. When used in the field of sightseeing, it needs to run for a long time during the day and will not stop until night. If the cableway is used to transport materials in some mountainous areas, it may be operated for a long time day and night without stopping. At this time, because the cable bears gravity, when the winch 501 runs for a long time, the cable itself and the winch 501 are connected by friction, so high temperature will definitely be generated. After long-term operation, the surface of the cable will soften. The softened cable will collide with collision objects during transportation, which will cause marks on the surface and reduce its service life. It is difficult to inspect or use the cables at high altitudes, so there is a risk of cable wear and breakage. Therefore, the whole device is provided with a self-lubricating device 502 and a cooling device. When the capstan 501 rotates one circle, it will drive the two sliding blocks 5021 to form abutment contact with the cross plate 8, and then use the inclined surface to slide with the cross plate 8, so as to control the sliding blocks 5021 to move downward synchronously, and then drive the linkage plate 5024 to move downward through the connection of the slide rod 5022, and then the linkage plate 5024 drives the oil collecting tank 5025 to move downward, and after the oil collecting tank 5025 moves downward, a part of the lubricating oil will be fished out and placed inside the oil collecting tank 5025. After that, when the sliding block 5021 is separated from the cross plate 8, it will be reset by the contraction of the extrusion spring 5023, controlling the sliding rod 5022 to move upward, thereby driving the oil collecting groove 5025 on the linkage plate 5024 to move upward and align with the oil hole 5026. At this time, the oil in the oil collecting groove 5025 will flow through the multiple oil holes 5026 into the outer surface of the winch 501 and the surface of the cable, lubricating the cable while also lubricating the winch 501. Because of the immersion of the oil, it can also provide a certain degree of cooling effect.The entire winch 501 is also provided with a cooling device. When the power shaft 506 rotates, it will drive the gear sleeve 503 fixedly connected thereto to rotate. The gear sleeve 503 is provided with teeth inside, and the meshing of the teeth drives multiple center gears 504 to rotate. Therefore, at this time, the center gear 504 will drive the blades 505 to rotate, and the blades 505 will draw in external air from the position of the air extraction hole 511, enter the internal cavity of the gear sleeve 503, and then be discharged to the inside of the air cavity 509 through the air intake groove 508. Then, the air cavity 509 is connected with the internal oil cavity 510 of the winch 501, so at this time, the air flow will also be discharged from the multiple oil holes 5026. After being discharged, the cable is cooled and the winch 501 is cooled. Moreover, the air flow directly acts on the inside of the oil cavity 510, so the oil can also be cooled to ensure the stability of each oil circulation lubrication process.
