[0047] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0048] It should be noted that when a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there can be a central component; when an component is considered to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time; when an component is considered to be "installed on" another component, it can be directly installed on the other component or there can be a central component at the same time. When an component is considered to be "set on" another component, it can be directly set on the other component or there can be a central component at the same time.

[0049] The present invention provides a traction machine 100 that is convenient for replacing the encoder 3. Figures 1 to 5 As shown, a machine base 1, a traction wheel 2, and a fixed structure 4, the machine base 1 has a support shaft 11, the traction wheel 2 is mounted on the support shaft 11, and is rotatably connected to the support shaft 11; the fixed structure 4 includes a front cover plate 41 and a limit member 42, the front cover plate 41 is mounted on the traction wheel 2, the end of the support shaft 11 close to the front cover plate 41 has a receiving groove 111, and the encoder 3 is located in the receiving groove 111; the first end of the limit member 42 is mounted on the support shaft 11, and the second end of the limit member 42 is mounted on the encoder 3, one end of the encoder 3 is penetrated by the front cover plate 41, and is rotatably matched with the front cover plate 41; the front cover plate 41 is provided with a through opening 411, and the front cover plate 41 has a first moving position and a second moving position, in the first moving position, the limit member 42 is at least partially located at the through opening 411; in the second moving position, the limit member 42 is blocked by the front cover plate 41.

[0050] Specifically, the inner side of the front cover plate 41 is used to be installed on the rotating part of the encoder 3, and the fixed part of the encoder 3 is fixed in the receiving groove 111 of the support shaft 11 by the limit member 42. When the front cover plate 41 is fixed to the traction wheel 2, the traction wheel 2 drives the front cover plate 41 to rotate synchronously, and a part of the encoder 3 keeps rotating synchronously with the traction wheel 2, so that the encoder 3 can monitor the rotation speed of the traction wheel 2. The corresponding end of the encoder 3 and the front cover plate 41 has a cable 32, which is used to pass through the base 1 and then be electrically connected to the control circuit board.

[0051] Moreover, during the process of disassembling the encoder, the front cover plate 41 can be made to have a first moving position and a second moving position by rotating the traction wheel 2. In the first moving position, the through opening 411 corresponds to the stopper 42, so that the connection position of the stopper 42 and the support shaft 11 is exposed relative to the front cover plate 41. The stopper 42 and the second fastener 421 on the support shaft 11 are disassembled by a tool to separate the stopper 42 from the support shaft 11. Then, the front cover plate 41 and the first fastener 412 on the traction wheel 2 are disassembled, and the encoder 3 on the front cover plate 41 is taken out to replace the encoder 3. Furthermore, the machine base 1 is located on one side of the traction wheel 2, and the machine base 1 supports the traction wheel 2 to rotate through the support shaft 11. During assembly, the machine base 1 can be fixed close to the wall, and the front front plate 41 at the front end of the traction wheel 2 is set away from the wall. The front end of the traction wheel 2 has a larger operating space. Therefore, the connection relationship between the support shaft 11 of this machine base 1 and the traction wheel 2 also facilitates the disassembly of the encoder 3 at the front end of the traction wheel 2.

[0052] In disassembling and assembling the encoder 3, the present invention further proposes a disassembling and assembling method, comprising the following steps:

[0053] Step 1: The encoder 3 is fixed to one end of the limiter 42, and one end of the encoder 3 is installed on the inner side of the front cover plate 41;

[0054] Step 2: Move the front cover plate 41, and place the encoder 3 into the receiving groove 111. The front cover plate 41 is located at the front end of the traction sheave 2;

[0055] Step 3: Rotate the front cover 41, so that the limiting member 42 is at least partially exposed relative to the front cover 41, and pass the tool through the through-hole 411 of the front cover 41 to fix the other end of the limiting member 42 to the front end of the support shaft 11; align the front cover 41 with the mounting hole of the traction wheel 2, and fix the front cover 41 to the front end of the traction wheel 2.

[0056] By means of the above disassembly and assembly method, the encoder 3 can be quickly replaced, thereby improving the work efficiency of maintenance.

[0057] Preferably, the encoder 3 includes a main body 33 and a rotating member 31, the front cover plate 41 has a protrusion 413 facing the encoder 3, the first end of the rotating member 31 is installed on the protrusion 413, and the second end of the rotating member 31 is rotatably connected to the main body 33; the limiting member 42 is at least partially bent, and the main body 33 is fixed to the limiting member 42.

[0058] Specifically, the rotating member 31 of the encoder 3 is fixed to the protrusion 413, and one end of the rotating member 31 passes through the protrusion 413. The protrusion 413 is used to increase the connection area between the rotating member 31 and the front end cover plate 41, and improve the stability of the rotating member 31 after being fixed to the front end cover plate 41, so that the front end cover plate 41 can drive the rotating member 31 to rotate stably when rotating. The main body 33 is fixed in the receiving groove 111 by the limit member 42. Since the protrusion 413 protrudes toward the receiving groove 111, the limit member 42 is bent in order to avoid the protrusion 413, thereby improving the installation flexibility of the encoder 3 in the receiving groove 111, and also meeting the requirement that the encoder 3 is fixed to the support shaft 11 through the limit member 42. Figure 4 It can be seen that the traction machine 100 fully utilizes the space of the accommodating groove 111 , so that the protrusion 413 , the limiting member 42 , and the encoder 3 are relatively compact at the front end of the traction wheel 2 .

[0059] Preferably, there are two through openings 411, and the two through openings 411 are symmetrically arranged; the limiting member 42 is provided with two symmetrical connection points on the support shaft 11, and the two connection points correspond to the two through openings 411. Specifically, there is a solid mounting portion 414 between the two through openings 411, and the mounting portion 414 is used to fix the rotating member 31 of the encoder 3, so that the front cover plate 41 drives the rotating member 31 of the encoder 3 to rotate, and the two through openings 411 correspond to the two connection points between the limiting member 42 and the support shaft 11, thereby improving the connection point position of the limiting member 42 and the support shaft 11, improving the stability of the limiting member 42 on the support shaft 11, and further limiting the position of the encoder 3 in the receiving groove 111.

[0060] Preferably, the fixed structure 4 also has a sealing cover plate 44, which is used to be installed on the front cover plate 41. The sealing cover plate 44 is used to seal the two openings 411 to prevent external dust and debris from entering the interior of the traction machine 100 through the openings 411, thereby avoiding affecting the normal operation of the encoder 3.

[0061] In some embodiments, the stopper 42 includes two first fixing plates 423, two connecting plates 424, and a second fixing plate 425. The two first fixing plates 423 are arranged opposite to each other and are both mounted on the support shaft 11. The second fixing plate 425 is attached to and fixed to the main body 33. One of the first fixing plates 423 is fixed to the first end of the second fixing plate 425 through one of the connecting plates 424, and the other first fixing plate 423 is fixed to the second end of the second fixing plate 425 through the other connecting plate 424. Specifically, the two first fixing plates 423 can be used to be fixed at two positions at the front end of the support shaft 11. The two first fixing plates 423 are fixed to the two ends of the second fixing plate 425 through the two connecting plates 424. The connecting plates 424 are arranged obliquely. The connecting plates 424 avoid the protrusions 413 and are fixed to the encoder 3. The second fixing plate 425 is attached to the main body 33 and is fixed to the main body 33 by bolts.

[0062] In some embodiments, Figure 2 , Figure 6 , Figure 7 As shown, the traction machine 100 also has a sealing structure 5 and a bearing 6. The bearing 6 is sleeved on the outside of the support shaft 11, and the traction wheel 2 is sleeved on the outside of the bearing 6 and is rotatably connected to the support shaft 11 through the bearing 6; the sealing structure 5 has an oil seal 51 and an oil drain pipe 55. The oil seal 51 is sleeved on the outside of the support shaft 11 and fixed to the traction wheel 2. The oil seal 51 is used to seal the end of the bearing 6; the outer wall of the base 1 close to the support shaft 11 is bent to form an oil storage chamber 52, and the bottom of the oil storage chamber 52 has an oil drain hole 521. The oil drain pipe 55 is arranged in the base 1, and the first end of the oil drain pipe 55 is connected to the oil drain hole 521, and the second end of the oil drain pipe 55 is located on the outer wall of the base 1; the first outer wall 201 of the traction wheel 2 is provided with at least one first oil separator 53, and the first oil separator 53 is extended along the circumference of the traction wheel 2, and the first oil separator 53 is located at the opening of the oil storage chamber 52.

[0063] Specifically, the oil seal 51 is used to seal the end of the bearing 6. When the oil seal 51 ages, the oil in the bearing 6 may penetrate into the outside of the oil seal 51 and flow into the opening of the oil storage chamber 52 along the outer wall of the traction wheel 2. The leaked oil will flow into the oil storage chamber 52 along the outer wall of the base 1. Since the first outer wall 201 of the traction wheel 2 has a first oil-isolating groove 53, the first oil-isolating groove 53 blocks the oil. As the traction wheel 2 rotates, the centrifugal force generated by the traction wheel 2 throws the oil into the oil storage chamber 52. As the oil in the oil storage chamber 52 accumulates, the oil in the oil storage chamber 52 flows into the oil drain pipe 55 through the oil drain hole 521. The oil drain pipe 55 discharges the oil in the oil storage chamber 52 to the outside of the machine base 1, preventing the oil from flowing along the outer wall of the traction wheel 2 or the machine base 1 to other positions of the traction machine 100, and preventing the leaked oil from damaging other components of the traction machine 100. Therefore, even if the traction machine 100 leaks oil, it can maintain normal operation.

[0064] Furthermore, since the machine base 1 is in a stationary state, the outer wall of the machine base 1 is bent to form an oil storage chamber 52, and the oil storage chamber 52 is also in a stationary state, and the first oil separator 53 rotates with the traction wheel 2, so that the oil on the outer wall of the traction wheel 2 can be splashed into the oil storage chamber 52 due to centrifugal force, and the first end of the oil drain pipe 55 can be fixed in the machine base 1 and connected to the oil drain hole 521 of the oil storage chamber 52. The structure designed in this way is more practical and will not interfere with the rotation of the traction wheel 2.

[0065] Preferably, the second end of the oil drain pipe 55 is connected to an oil collecting box 57 , and the oil collecting box 57 is used to collect grease leaked from the bearing 6 .

[0066] In this embodiment, the front end of the traction wheel 2 has an oil filling port 22 and an oil delivery channel. The oil filling port 22 is connected to the first end of the oil delivery channel, and the second end of the oil delivery channel is connected to the bearing 6. When the oil in the bearing 6 is used up, lubricating oil is injected from the front end oil filling port 22 of the traction wheel 2, and the lubricating oil enters the bearing 6 through the oil delivery channel. This oil filling method is extremely convenient.

[0067] Preferably, there is a gap 54 between the first outer wall 201 of the traction wheel 2 and the inner wall of the base 1, and the gap 54 is located at the top of the oil storage chamber 52 and is arranged away from the oil drain hole 521; the first oil separation groove 53 is arranged between the oil drain hole 521 and the gap 54. Specifically, there is a gap 54 between the traction wheel 2 and the base 1 to prevent the base 1 from interfering with the rotation of the traction wheel 2, and the gap 54 is located at the top of the oil storage chamber 52. Only when the oil in the oil storage chamber 52 cannot be discharged and is filled, the oil in the oil storage chamber 52 is likely to overflow from the gap 54. Therefore, when the oil drain pipe 55 is unobstructed, the probability of the oil in the oil storage chamber 52 overflowing from the gap 54 is very small, and the oil overflowing from the gap 54 is avoided.

[0068] Furthermore, a vertical retaining wall 522 is provided on one side of the oil storage chamber 52 close to the gap 54 . When the oil storage chamber 52 is not full of oil, the retaining wall 522 can prevent the oil in the oil storage chamber 52 from leaking from the side close to the gap 54 .

[0069] Preferably, the traction wheel 2 has a second outer wall 202, the first outer wall 201 is arranged close to the center of the traction wheel 2, and the second outer wall 202 is arranged away from the center of the traction wheel 2; at least one second oil separation groove 56 is provided on the second outer wall 202, and the second oil separation groove 56 is extended along the circumference of the traction wheel 2. Specifically, if the oil in the oil storage chamber 52 overflows from the gap 54 and flows outward along the outer wall of the traction wheel 2, the second oil separation groove 56 is provided on the second outer wall 202 of the traction wheel 2, and the second oil separation groove 56 blocks the oil in the second outer wall 202. The second oil separation groove 56 rotates with the traction wheel 2, and the traction wheel 2 throws the oil into the elevator shaft to prevent the oil from flowing along the outer wall of the traction wheel 2 onto the brake disc 21. The oil will reduce the friction of the brake disc 21, so it is necessary to prevent the oil from affecting the normal use of the brake disc 21.

[0070] Preferably, the traction sheave 2 further comprises a brake disc 21, which is arranged to extend along the circumference of the traction sheave 2 and is arranged away from the second oil separation groove 56. This can further prevent oil from falling onto the brake disc 21, which cooperates with a brake, and the brake is used for emergency braking of the brake disc 21.

[0071] In some embodiments, the sealing structure 5 further has a wear-resistant kit 43, the outer wall of the support shaft 11 is coated with a layer of sealant 58, the wear-resistant kit 43 is sleeved outside the support shaft 11, and the sealant 58 is located between the wear-resistant kit 43 and the support shaft 11; the wear-resistant kit 43 is rotatably connected with the oil seal 51. Specifically, the wear-resistant kit 43 contacts the oil seal 51, meets the surface roughness and hardness of the contact surface with the inner ring lip of the oil seal 51, avoids direct contact between the support shaft 11 and the oil seal 51, and improves the service life of the oil seal 51. There is a layer of sealant 58 between the wear-resistant kit 43 and the support shaft 11, which can further prevent oil from leaking from the bearing 6.

[0072] In some embodiments, the end of the bearing 6 near the front cover plate 41 also has a wear-resistant kit 43 and an oil seal 51. The wear-resistant kit 43 here is in a bent shape. One end of the wear-resistant kit 43 is fixed to the end of the support shaft 11, and the other end of the wear-resistant kit 43 is rotatably connected to the oil seal 51. The oil seal 51 and the wear-resistant kit 43 block the end of the bearing 11. Moreover, the wear-resistant kit 43 at the front end of the support shaft 11 is at least partially located at the through port 411. When oil leakage occurs at the end of the bearing 6 at the front end of the support shaft 11, it is possible to observe whether there is grease in the wear-resistant kit 43 through the through port 411, thereby monitoring the oil leakage at both ends of the bearing 6.

[0073] Therefore, the opening 411 in the front cover plate 41 can facilitate the disassembly and assembly of the encoder 3 , and can also be used as an observation window to regularly observe whether there is oil leakage at the front end of the bearing 6 .
