Description

Technical Field

[0001] The utility model belongs to the technical field of machine room elevator traction machine, and specifically relates to an anti-wear device for a machine room-less elevator traction machine. Background Art

[0002] With the acceleration of urbanization and the continuous emergence of high-rise buildings, the importance of elevators as vertical transportation tools has become increasingly prominent. Machine room-less elevators have been widely used because they do not require a separate machine room, have compact structure and high space utilization.

[0003] In a machine room-less elevator, the traction machine is one of the key components. It drives the rotation of the traction sheave through the rotating shaft to realize the operation of the elevator. However, in actual use, the traction sheave and traction wire rope are prone to wear, which is mainly caused by the following reasons:

[0004] 1. Dust accumulation: Due to the particularity of the elevator working environment, dust in the air easily accumulates inside the guide groove of the traction wheel and on the traction wire rope. The presence of dust will increase the friction between the traction wire rope and the traction wheel, resulting in increased wear.

[0005] 2. Lack of effective cleaning: Traditional elevator maintenance methods often make it difficult to completely remove dust from the traction sheave and traction wire rope, causing dust to accumulate over a long period of time, which has an adverse effect on the operation of the elevator.

[0006] These problems will not only reduce the service life of the traction wire rope and traction wheel, increase maintenance costs, but may also affect the operating stability and safety of the elevator. To this end, we have proposed an anti-wear device that can effectively solve these problems. The device can remove dust from the traction wire rope and traction wheel, thereby effectively reducing the impact of dust, increasing the service life of the traction wire rope and traction wheel, and achieving an anti-wear effect. Utility Model Content

[0008] The technical solutions adopted in this utility are as follows:

[0009] A wear-proof device for a traction machine of a machine room-less elevator comprises a base and a traction machine body arranged on the top of the base, a rotating shaft is arranged on the traction machine body, a brake is installed at one end of the rotating shaft, a traction wheel is installed at the end of the brake away from the rotating shaft, a guide groove is opened on the traction wheel, and a traction wire rope is arranged inside the guide groove;

[0010] Two second fixed blocks and two symmetrical first fixed blocks are provided on the base, two first rotating shafts are provided between the two first fixed blocks, a first debris removing roller is provided between the two first rotating shafts, the first debris removing roller is fitted with the traction wheel, one of the first rotating shafts is connected to the rotating shaft through a transmission belt, a first gear is sleeved on the other first rotating shaft, two second gears are provided on the outer side of the first gear, the second gear is sleeved on the second rotating shaft, one end of the second rotating shaft is rotatably set on the second fixed block, and a second debris removing roller is installed on the other end of the second rotating shaft, and the second debris removing roller is fitted with the traction wire rope.

[0011] Furthermore, a through slot is provided on the base.

[0012] Furthermore, both the first and second impurity removing rollers are provided with impurity removing brushes.

[0013] Furthermore, the guide groove matches the traction wire rope.

[0014] The technical effects achieved by this utility model are:

[0015] When the traction machine body rotates, the rotating shaft rotates, and the rotating shaft drives the transmission belt to rotate the first rotating shaft on the first fixed block. When the first rotating shaft rotates, it drives the first dust removal roller to remove the dust inside the traction wheel guide groove, thereby reducing the friction of dust on the traction wire rope. At the same time, when the first rotating shaft rotates, it drives the first gear to rotate, and the first gear drives the two second gears to rotate on the second fixed block.

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0025] like Figure 1-6 As shown, the technical solution adopted by the utility model is as follows: a wear-proof device for a traction machine of a machine room-less elevator, comprising a base 1 and a traction machine body arranged on the top of the base 1, a rotating shaft 2 is arranged on the traction machine body, a brake is installed at one end of the rotating shaft 2, a traction wheel 3 is installed at the end of the brake away from the rotating shaft 2, a guide groove 4 is opened on the traction wheel 3, and a traction wire rope 5 is arranged inside the guide groove 4;

[0026] Two second fixed blocks 6 and two symmetrical first fixed blocks 7 are provided on the base 1, two first rotating shafts 8 are provided between the two first fixed blocks 7, a first debris removing roller 9 is provided between the two first rotating shafts 8, the first debris removing roller 9 is fitted with the traction wheel 3, one of the first rotating shafts 8 is connected to the rotating shaft 2 through a transmission belt 10, a first gear 11 is sleeved on the other first rotating shaft 8, two second gears 12 are provided on the outside of the first gear 11, the second gear 12 is sleeved on the second rotating shaft 13, one end of the second rotating shaft 13 is rotatably set on the second fixed block 6, and a second debris removing roller 14 is installed on the other end of the second rotating shaft 13, and the second debris removing roller 14 is fitted with the traction wire rope 5.

[0027] Its working principle is: when the elevator is running, the traction machine body works, the traction machine body drives the rotating shaft 2 to rotate the traction wheel 3, and the traction wheel 3 drives the traction wire rope 5 to work when rotating, so that the elevator works, and the stop and operation of the elevator are controlled by the brake. However, when the traction wheel 3 is working, the whole device is outside the elevator. Over time, dust in the air will adhere to the inside of the guide groove 4 of the traction wheel 3 and the traction wire rope 5. At this time, during work, the dust will increase the friction between the traction wire rope 5 and the traction wheel 3. Over time, the traction wire rope 5 and the traction wheel 3 will be excessively worn, causing damage to the elevator. For this reason, the present invention is used to prevent the traction wheel 3 from being damaged. The utility model rotates the rotating shaft 2 when the traction machine body rotates, and the rotating shaft 2 drives the transmission belt 10 to rotate the first rotating shaft 8 on the first fixed block 7. When the first rotating shaft 8 rotates, it drives the first impurity removal roller 9 to remove the dust inside the guide groove 4 of the traction wheel 3, thereby reducing the friction of dust on the traction wire rope 5. At the same time, when the first rotating shaft 8 rotates, it drives the first gear 11 to rotate, and the first gear 11 drives the two second gears 12 to rotate on the second fixed block 6. The second gear 12 drives the second rotating shaft 13 to make the second impurity removal roller 14 remove the dust on the contact surface of the traction wire rope 5 and the traction wheel 3, thereby further reducing the influence of dust. The device can remove dust on the traction wire rope 5 and the traction wheel 3, thereby effectively reducing the influence of dust, increasing the service life of the traction wire rope 5 and the traction wheel 3, and achieving the effect of anti-wear.

[0028] A through groove is provided on the base 1, and the through groove enables the traction wire rope 5 to be transported.

[0029] At the same time, the first and second cleaning rollers 9 and 14 are both provided with cleaning brushes 15 . The cleaning brushes 15 are soft brushes that can be deformed. The cleaning effect can be improved by the cleaning brushes 15 .

[0030] The first gear 11 is meshed with the second gear 12 , and such an arrangement enables the first gear 11 to drive the second gear 12 to rotate when rotating.

[0031] The brake includes a braking electromagnet 16, a gate wheel 17, a pin shaft 18, a braking spring 19, a brake shoe 20 and a brake arm 21. One end of the gate wheel 17 is connected to the rotating shaft 2, and the other end is connected to the traction wheel 3. A braking electromagnet 16 is arranged on the top of the gate wheel 17, and brake shoes 20 are arranged on both sides of the gate wheel 17. The brake shoe 20 is hinged on the brake arm 21. The brake arm 21 is connected to the base 1 through the pin shaft 18, and the brake arm 21 is connected to the braking electromagnet 16 through the connecting shaft 22, and the connecting shaft 22 is provided with a braking spring 19.

[0032] When the elevator is in a stationary state, the coil inside the brake electromagnet 16 has no current, the brake electromagnet 16 does not move, and the brake shoe 20 holds the brake wheel 17 tightly under the pressure of the brake spring 19. When the elevator is working, the coil inside the brake electromagnet 16 is energized with current, the brake electromagnet 16 moves, and the brake arm 21 will quickly tighten the brake spring 19, so that the brake shoe 20 is pulled open, thereby making the brake wheel 17 work.

[0033] It should be noted that the brake belongs to the prior art, and its working principle and operation principle are all prior art, and no further elaboration will be made here.

[0034] The guide groove 4 matches the traction wire rope 5. Matching here means that the traction wire rope 5 can move smoothly inside the guide groove 4 without getting stuck.

[0035] The traction machine body includes a bracket arranged on a base 1 , on which a traction motor 23 is arranged, and an output end of the traction motor 23 is connected to the rotating shaft 2 , so that the rotating shaft 2 is driven to rotate by the traction motor 23 .

[0036] The working principle of the utility model is as follows: when the elevator is running, the traction machine body works, the traction machine body drives the rotating shaft 2 to rotate the traction wheel 3, and the traction wheel 3 drives the traction wire rope 5 to work when rotating, so that the elevator works, and the stop and operation of the elevator are controlled by the brake. However, when the traction wheel 3 is working, the whole device is outside the elevator, and over time, dust in the air will adhere to the inside of the guide groove 4 of the traction wheel 3 and the traction wire rope 5. At this time, when working, the dust will increase the friction between the traction wire rope 5 and the traction wheel 3, and over time, the traction wire rope 5 and the traction wheel 3 will be excessively worn, causing damage to the elevator. For this reason The utility model rotates the rotating shaft 2 when the traction machine body rotates, and the rotating shaft 2 drives the transmission belt 10 to rotate the first rotating shaft 8 on the first fixed block 7. When the first rotating shaft 8 rotates, it drives the first dust removal roller 9 to remove the dust inside the guide groove 4 of the traction wheel 3, thereby reducing the friction of dust on the traction wire rope 5. At the same time, when the first rotating shaft 8 rotates, it drives the first gear 11 to rotate, and the first gear 11 drives the two second gears 12 to rotate on the second fixed block 6. The second gear 12 drives the second rotating shaft 13 to make the second dust removal roller 14 remove the dust on the contact surface between the traction wire rope 5 and the traction wheel 3, thereby further reducing the influence of dust. The device can remove dust on the traction wire rope 5 and the traction wheel 3, thereby effectively reducing the influence of dust, increasing the service life of the traction wire rope 5 and the traction wheel 3, and achieving the effect of anti-wear.

[0037] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
