In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0043] In the prior art, the measuring device is far away from the outside of the traction machine, resulting in a large space required for disassembling and installing the measuring device. Moreover, in some cases, the measuring device needs to be displaced in multiple directions in order to install and disassemble the measuring device, which further results in a large space required for disassembling and installing the measuring device. Therefore, in the prior art, a large space needs to be reserved for installing and disassembling the measuring device, which makes it difficult to install and disassemble the measuring device in a small space of the traction machine.

[0044] In order to at least solve the problem that the space required for disassembling and installing the measuring device is large, which makes it difficult for the traction machine to install and disassemble the measuring device in a narrow space, the embodiment of the utility model provides a traction machine 100, which requires less space to disassemble the first stator 41 and the rotor assembly 44 of the rotary transformer device 4, and can install and disassemble the first stator 41 and the rotor assembly 44 in a narrow space.

[0045] The embodiment of the present utility model further provides an elevator system including the traction machine 100 of the above embodiment.

[0046] Combine the following Figures 1 to 8 The traction machine 100 and the elevator system according to the embodiment of the present invention are described.

[0047] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the traction machine 100 of the embodiment of the utility model comprises: a machine base 1, a traction wheel 2, a driving assembly 3 and a rotary transformer 4, wherein the driving assembly 3 is arranged on the machine base 1, the driving assembly 3 is connected to the traction wheel 2 and can drive the traction wheel 2 to rotate; the rotary transformer 4 comprises a first stator 41 and a rotor assembly 44 which cooperate with each other, the first stator 41 and the rotor assembly 44 are both located on a first side of the machine base 1 along a first direction, the first stator 41 is arranged on the machine base 1 in a detachable form along the first direction, the rotor assembly 44 is connected to the driving assembly 3 in a detachable form along the first direction, and can be driven to rotate circumferentially along the first stator 41.

[0048] The first direction is parallel to the rotation axis direction of the traction wheel 2. As an example, the first direction is as follows: Figure 3 As indicated by the arrow at a in the middle.

[0049] The first side is one side of the base 1 along the first direction. For example, the first side is Figure 3 As indicated by the arrow at d in the middle.

[0050] The driving assembly 3 is connected to the traction wheel 2 so as to be able to drive the traction wheel 2 to rotate. The driving assembly 3 is also connected to the rotor assembly 44 of the rotary transformer 4. Thus, the angular velocity and angular displacement of the traction wheel 2 can be reflected by the angular velocity and angular displacement of the rotor assembly 44, so that the rotary transformer 4 can measure the angular velocity and angular displacement of the traction wheel 2.

[0051] Since the rotor assembly 44 and the first stator 41 are both located on the first side of the base 1 , the rotor assembly 44 and the first stator 41 are easy to disassemble and install, so that the first stator 41 and the rotor assembly 44 can be installed and disassembled in a narrow space.

[0052] Since the first stator 41 and the rotor assembly 44 are both detachably arranged along the first direction, the first stator 41 and the rotor assembly 44 can be installed and disassembled by displacing them in the first direction, thereby further reducing the space required for installing and disassembling the rotor assembly 44 and the first stator 41, so that the first stator 41 and the rotor assembly 44 can be installed and disassembled in a narrow space.

[0053] In addition, the rotary transformer 4 of the embodiment of the utility model measures the angular velocity and angular displacement of the traction wheel 2 through the rotor assembly 44 and the first stator 41. The rotary transformer 4 is not provided with electronic components, so that the rotary transformer 4 of the embodiment of the utility model has strong anti-interference ability and high reliability.

[0054] The traction machine 100 of the embodiment of the utility model makes the rotor assembly 44 and the first stator 41 both located on the first side of the machine base 1, so that the rotor assembly 44 and the first stator 41 are easy to disassemble and install, so that the first stator 41 and the rotor assembly 44 can be installed and disassembled in a narrow space. By making the first stator 41 and the rotor assembly 44 both detachably arranged along the first direction, so that the first stator 41 and the rotor assembly 44 are displaced in the first direction, the installation and disassembly of the first stator 41 and the rotor assembly 44 can be achieved, so that the first stator 41 and the rotor assembly 44 can be further installed and disassembled in a narrow space.

[0055] The weight of the elevator car and the counterweight are unbalanced, and the car will roll back when it starts. When there are more passengers in the car and the weight of the car is greater than the counterweight, the car will slide upward. When there are fewer passengers in the car and the weight of the car is less than the counterweight, the car will slide downward. Therefore, compensation needs to be made when the car starts, so as to reduce the probability of the car rolling back after starting.

[0056] In some embodiments of the utility model, when the car is ready to start, the car is caused to roll back in a small range, the angular velocity of the rotor assembly 44 relative to the first stator 41 is obtained, and the torque output by the drive assembly 3 to the traction sheave 2 is determined according to the angular velocity of the rotor assembly 44 to compensate for the torque output by the traction sheave 2, thereby reducing the probability of the car rolling back after starting. Thus, the compensation torque for the traction sheave 2 before the car starts can be determined through the rotor assembly 44 and the first stator 41.

[0057] The elevator system of the embodiment of the utility model includes the traction machine 100 as described in the above embodiment, which can install and disassemble the first stator 41 and the rotor assembly 44 in a narrow space. Therefore, the elevator system of the embodiment of the utility model can reduce the reserved space for installing and disassembling the rotor assembly 44 and the first stator 41, thereby improving the space utilization of the hoistway.

[0058] In some specific embodiments, the elevator system further includes a car, a counterweight and a traction rope. The traction machine 100, the car, the counterweight and the traction rope are all arranged in the hoistway. The car and the counterweight are located on both sides of the traction wheel 2 along the third direction, and the traction rope includes a first rope segment, a second rope segment and a third rope segment, and the first rope segment and the third rope segment both extend along the second direction, and the first rope segment and the third rope segment are arranged oppositely and spaced in the third direction. One end of the first rope segment is connected to the counterweight, the other end of the first rope segment is connected to one end of the second rope segment, one end of the third rope segment is connected to the car, and the other end of the third rope segment is connected to the other end of the second rope segment, and at least part of the second rope segment is wound around the traction wheel 2. The traction machine 100 causes the car to move up and down in the hoistway by traction of the second rope segment, so that the elevator system can carry passengers. The first direction, the second direction and the third direction are perpendicular to each other.

[0059] As an example, the second direction is the up-down direction, such as Figure 3 As indicated by the arrow at b.

[0060] As an example, the third direction is a horizontal direction perpendicular to the first direction.

[0061] Furthermore, the elevator system further includes a guide rail, which is arranged in the hoistway, and the car is movably arranged on the guide rail to be guided by the guide rail, and the rotor assembly 44 and the first stator 41 are both arranged relative to the guide rail in the first direction. Since the space required for installing and disassembling the rotor assembly 44 and the first stator 41 is small, the gap between the traction machine 100 and the guide rail in the embodiment of the utility model is small, so that the space utilization rate of the hoistway is large. In some cases, improving the space utilization rate of the hoistway can increase the area of ​​the car, thereby improving the transportation efficiency of the car.

[0062] Combination Figure 3 and Figure 4 As shown, in some embodiments of the utility model, the rotary transformer 4 also includes a fixed component 43 and a first rotor 42 located on the first side, the first rotor 42 is connected to the fixed component 43, the fixed component 43 is connected to the drive component 3 in a detachable form along the first direction, and can be driven by the drive component 3 so that the first rotor 42 can rotate along the circumferential direction of the first stator 41.

[0063] When the first rotor 42 needs to be installed or removed, the fixing member 43 is installed or removed along the first direction, so that the first rotor 42 can be installed or removed along the first direction.

[0064] The first rotor 42 is indirectly connected to the driving assembly 3 through the fixing member 43. The driving assembly 3 drives the fixing member 43, and the fixing member 43 drives the first rotor 42 located on the fixing member 43 to rotate along the circumferential direction of the first stator 41. By providing the fixing member 43, the first rotor 42 can be placed in a reasonable position to cooperate with the first stator 41, so that the internal structure of the traction machine 100 of the embodiment of the utility model is reasonable.

[0065] Combination Figure 3 and Figure 4 As shown, in some embodiments of the utility model, the fixed component 43 includes a fixed disk 431 and a fixed plate 432 that are connected to each other, and the first rotor 42 is clamped between the fixed disk 431 and the fixed plate 432 in a first direction. The fixed disk 431 is connected to the driving component 3 in a detachable form along the first direction and can be driven by the driving component 3 so that the first rotor 42 can rotate circumferentially along the first stator 41.

[0066] The first rotor 42 is installed by clamping the first rotor 42 between the fixing disk 431 and the fixing plate 432, so that the first rotor 42 can be easily installed and removed from the fixing disk 431 and the fixing plate 432. In addition, the fixing disk 431 and the fixing plate 432 have simple structures and are easy to produce and assemble.

[0067] Optionally, the fixing disk 431 is connected to the fixing plate 432 via a threaded member. The threaded member can provide a more stable connection between the fixing disk 431 and the fixing plate 432. The threaded member is a connecting member with threads, such as a screw, a bolt, etc.

[0068] like Figure 3 As shown, in some embodiments of the utility model, the traction machine 100 includes a bearing 6 and a bearing end cover 7, the bearing 6 is arranged on the machine base 1, the bearing 6 is sleeved on the outside of the machine base 1, and is clamped between the machine base 1 and the driving assembly 3, one end of the bearing end cover 7 in the first direction abuts against the bearing 6, the fixed plate 431 is connected to the other end of the bearing end cover 7 in the first direction in a form that is detachable along the first direction, the bearing end cover 7 is connected to the driving assembly 3, and can be driven by the driving assembly 3 so that the first rotor 42 can rotate circumferentially along the first stator 41.

[0069] The bearing 6 can be installed through the bearing end cover 7 to prevent the bearing 6 from being misplaced when the traction machine 100 is running. The fixed plate 431 is connected to the drive assembly 3 through the bearing end cover 7 in the first direction, so that the size of the fixed plate 431 in the first direction can be reduced, so that the fixed plate 431 can be connected to the drive assembly 3 with a smaller size in the first direction, thereby further reducing the space required for installing and disassembling the first rotor 42 and the first stator 41. For example, in some cases, the first rotor 42 and the first stator 41 can be disassembled by reserving a space of 5 mm.

[0070] In addition, by connecting the bearing end cover 7 to the fixed plate 431, it is possible to avoid setting up additional parts to reduce the size of the fixed plate 431, thereby reducing the number of parts of the traction machine 100 of the embodiment of the utility model and increasing the space utilization of the traction machine 100 of the embodiment of the utility model, thereby making the structure of the traction machine 100 more compact.

[0071] like Figure 4 As shown, further, the fixed disk 431 is provided with a fixed groove 4313, the first rotor 42 is inserted into the fixed groove 4313, the fixed groove 4313 has a groove wall arranged opposite to the fixed plate 432 in the first direction, the groove wall abuts against one end of the first rotor 42 in the first direction, and the fixed plate 432 abuts against the other end of the first rotor 42 in the first direction.

[0072] The first rotor 42 is fixed by the fixing groove 4313 , thereby increasing the fixing effect of the fixing plate 431 on the first rotor 42 , so that the first rotor 42 can be more firmly installed between the fixing plate 431 and the fixing plate 432 .

[0073] In addition, the fixing groove 4313 can also guide and position the first rotor 42, thereby reducing the difficulty of assembling the first rotor 42 and the fixing plate 431, thereby facilitating installation.

[0074] Combination Figure 3 and Figure 4 As shown, in some embodiments of the utility model, the fixed disk 431 is located on the same side of the base 1 and the driving assembly 3 in the first direction, and an installation space 4311 is defined between the fixed disk 431, the base 1 and the driving assembly 3, and the fixed plate 432, the first rotor 42 and the first stator 41 are all located in the installation space 4311.

[0075] The first rotor 42 and the first stator 41 located in the installation space 4311 are protected by the fixing plate 431, thereby reducing the probability of the first rotor 42 and the first stator 41 being damaged by collision with foreign objects. In addition, the first rotor 42 and the first stator 41 located in the installation space 4311 can also reduce the probability of contact with water, thereby reducing the probability of the first rotor 42 and the first stator 41 being short-circuited by water.

[0076] Furthermore, the fixed disk 431 , the base 1 and the driving assembly 3 are all sealed and connected, thereby further reducing the probability of the first rotor 42 and the first stator 41 being short-circuited when encountering water.

[0077] Combination Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the traction wheel 2 has a first end face 21 at one end along the first direction, and the first end face 21 is located at the first side, and the fixed plate 431 has a second end face 4312 at one end along the first direction away from the machine base 1, and the second end face 4312 is located between the first end face 21 and the machine base 1, or the second end face 4312 is flush with the first end face 21 in the first direction. In other words, the size of the traction machine 100 in the embodiment of the present invention in the first direction is not affected by the fixed plate 431, that is, the setting of the fixed plate 431 in the embodiment of the present invention can prevent the size of the traction machine 100 in the first direction from increasing.

[0078] By locating the second end face 4312 between the first end face 21 and the machine base 1, or by flushing the second end face 4312 with the first end face 21 in the first direction, the fixed plate is prevented from increasing the size of the traction machine 100 in the first direction, so that the traction machine 100 can maintain a smaller size in the first direction, thereby reducing the space occupied by the traction machine 100 in the shaft, and further increasing the space utilization of the shaft.

[0079] Combination Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments of the present invention, the base 1 includes a spindle 11 extending in a first direction and a fixing seat 12 arranged on the spindle 11 along the circumference of the spindle 11, the spindle 11 has a first side and a second side arranged opposite to each other in the first direction, and the fixing seat 12 is arranged on the second side of the spindle 11. That is, the first stator 41 and the first rotor 42 are both located on the first side of the spindle 11.

[0080] The first side is one side of the mandrel 11 along the first direction, and the second side is the other side of the mandrel 11 along the first direction. Figure 4 As shown in the middle d, the second side is Figure 4 As shown in point e in the middle.

[0081] The machine base 1 includes a spindle 11 extending in a first direction and a fixing seat 12 circumferentially arranged on the spindle 11, so that the overall structure of the machine base 1 is compact. The traction wheel 2, the drive assembly 3, and the rotary transformer 4 can be directly or indirectly arranged on the spindle 11 and the fixing seat 12 along the first direction, so that the traction machine 100 of the embodiment of the utility model has a compact structure.

[0082] Specifically, the fixed seat 12 includes a seat body 121 and a connecting portion 122. The seat body 121 is arranged around the spindle 11 along the circumference of the spindle 11, and the connecting portion 122 is arranged around the spindle 11 along the circumference of the spindle 11, and the connecting portion 122 is located between the seat body 121 and the spindle 11 in the radial direction of the traction wheel 2, one end of the connecting portion 122 in the radial direction of the traction wheel 2 is connected to the seat body 121, and the other end of the connecting portion 122 in the radial direction of the traction wheel 2 is connected to the spindle 11, and the size of the connecting portion 122 in the first direction is smaller than the size of the seat body 121 in the first direction.

[0083] The seat body 121 and the spindle 11 are connected by the connecting portion 122, which can reduce the overall material of the fixed seat 12 while ensuring the strength of the base 1, and can reduce the weight of the base 1, thereby reducing the cost of the base 1 and reducing the weight of the traction machine 100 of the embodiment of the utility model.

[0084] like Figure 7 As shown, optionally, a first reinforcing rib 1221 is provided on one side of the connecting portion 122 in the first direction, one end of the first reinforcing rib 1221 is connected to the seat body 121, and the other end of the first reinforcing rib 1221 is connected to the connecting portion 122. The first reinforcing rib 1221 increases the structural strength between the connecting portion 122 and the seat body 121, and reduces the probability of damage to the connecting portion 122 and the seat body 121.

[0085] like Figure 7 As shown, further, a plurality of first reinforcing ribs 1221 are provided, and the plurality of first reinforcing ribs 1221 are arranged at circumferential intervals along the central shaft 11, so as to further increase the structural strength between the connecting portion 122 and the seat body 121, and further reduce the probability of damage to the connecting portion 122 and the seat body 121.

[0086] like Figure 7As shown, in some optional embodiments, the other side of the connecting portion 122 in the first direction is provided with a second reinforcing rib 1222, one end of the second reinforcing rib 1222 in the first direction is connected to the connecting portion 122, one end of the second reinforcing rib 1222 in the radial direction of the traction wheel 2 is connected to the seat body 121, and the other end of the second reinforcing rib 1222 in the radial direction of the traction wheel 2 is connected to the spindle 11. The second reinforcing rib 1222 is provided to increase the structural strength between the connecting portion 122, the seat body 121 and the spindle 11, thereby reducing the probability of damage to the connecting portion 122, the seat body 121 and the spindle 11.

[0087] like Figure 7 As shown, in some further embodiments, a plurality of second reinforcing ribs 1222 are provided, and the plurality of second reinforcing ribs 1222 are arranged at circumferential intervals along the central shaft 11, thereby further increasing the structural strength between the connecting part 122, the seat body 121 and the central shaft 11, and further reducing the probability of damage to the connecting part 122, the seat body 121 and the central shaft 11.

[0088] In some embodiments, multiple first reinforcing ribs 1221 and multiple second reinforcing ribs 1222 are staggered in the circumferential direction of the core shaft 11 to avoid multiple reinforcement of the same part of the connecting portion 122 by the first reinforcing ribs 1221 and the second reinforcing ribs 1222, so that the positions of the first reinforcing ribs 1221 and the second reinforcing ribs 1222 are reasonably set, thereby making the strength of the connecting portion 122 reasonable.

[0089] Combination Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments of the utility model, the main shaft 11 is provided with a receiving hole 111 that passes through the main shaft 11 along the first direction, and the rotary transformer device 4 also includes a signal line (not shown in the figure) connected to the signal of the first stator 41, and a part of the signal line is passed through the receiving hole 111.

[0090] By providing the receiving hole 111, the signal line can be led out through the receiving hole 111, so that the signal can be transmitted to the circuit system. The mandrel 11 can also protect the signal line, thereby reducing the probability of signal damage.

[0091] In the prior art, when the traction machine brakes, the brake structure in contact with the brake pad is greatly deformed. The brake microswitch of the traction machine is arranged near the brake structure. The large deformation of the brake structure can easily cause the brake microswitch to malfunction, thereby easily causing a malfunction.

[0092] Combination Figure 3 and Figure 8As shown, in some embodiments of the utility model, the driving assembly 3 includes a second stator 31 and a second rotor 32, the second stator 31 is installed on the fixed seat 12, the second rotor 32 includes a vertical plate 321 and a brake plate 322, the traction wheel 2 and the rotor assembly 44 are connected to the vertical plate 321, the vertical plate 321 is rotatably mounted on the spindle 11, the brake plate 322 is arranged opposite to the second stator 31 in the radial direction of the traction wheel 2, the traction machine 100 is also provided with a brake device 5, the brake plate 322 is provided with a brake part 3221, the brake device 5 is arranged opposite to the brake part 3221 in the radial direction of the traction wheel 2, and can contact the brake part 3221 to be able to decelerate the brake plate 322, and the vertical plate 321 is connected to the brake part 3221 to be able to support the brake part 3221.

[0093] The rotor assembly 44 may be directly connected to the vertical plate 321 , or the rotor assembly 44 may be indirectly connected via the bearing end cover 7 .

[0094] When braking, the brake device 5 abuts against the braking part 3221 of the brake plate 322 to slow down the brake plate 322, and the vertical plate 321 supports the braking part 3221, thereby reducing the deformation degree of the braking part 3221 and the brake plate 322, and further reducing the probability of malfunction of the brake microswitch.

[0095] In addition, since the vertical plate 321 supports the braking part 3221 , the structural strength of the braking part 3221 is relatively large, and when the brake device 5 abuts against the braking part 3221 , the braking part 3221 is not easily damaged.

[0096] In addition, the brake device 5 performs braking by abutting against the brake plate 322 of the second stator 31, thereby avoiding the use of brake pads, and further reducing the number of parts of the traction machine 100, so as to simplify the structural complexity of the traction machine 100 of the embodiment of the utility model, and also reduce the overall size of the traction machine 100 of the embodiment of the utility model, so that the structure of the traction machine 100 of the embodiment of the utility model is compact.

[0097] In addition, the second stator 31 and the second rotor 32 of the embodiment of the utility model are easy to separate, so that the difficulty of installing and disassembling the second stator 31 and the second rotor 32 can be reduced.

[0098] Optionally, the brake plate 322 is disposed around the outer periphery of the second stator 31 along the circumferential direction of the second stator 31. In other words, the drive assembly 3 is an outer stator structure with a higher output torque and output power.

[0099] Specifically, the vertical plate 321 is rotatably mounted on the central shaft 11 through a bearing, one end of the bearing end cover 7 in the first direction abuts against the bearing 6, and the fixed plate 431 is connected to the other end of the bearing end cover 7 in the first direction in a detachable form along the first direction. The bearing end cover 7 is connected to the vertical plate 321 and can be driven by the vertical plate 321 so that the first rotor 42 can rotate circumferentially along the first stator 41.

[0100] The fixed disk 431 is connected to the vertical plate 321 in the first direction through the bearing end cover 7, so that the size of the fixed disk 431 in the first direction can be reduced, so that the fixed disk 431 can be connected to the vertical plate 321 by setting a smaller size in the first direction, thereby further reducing the space required for installing and disassembling the first rotor 42 and the first stator 41.

[0101] In addition, by connecting the bearing end cover 7 to the fixed plate 431, it is possible to avoid setting up additional parts to reduce the size of the fixed plate 431, thereby reducing the number of parts of the traction machine 100 of the embodiment of the utility model and increasing the space utilization of the traction machine 100 of the embodiment of the utility model, thereby making the structure of the traction machine 100 more compact.

[0102] Optionally, two bearings 6 are provided, and the two bearings 6 are installed back to back along the first direction. By installing the two bearings 6 back to back, the bearings 6 can withstand a higher overturning moment, so that the bearings 6 have higher stability. Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments of the utility model, the machine base 1 also includes a base 13, the base 13 includes a first support portion 131 and a second support portion 132 connected to each other, the first support portion 131 is connected to the fixed base 12, and the second support portion 132 is opposite to the traction wheel 2 in a second direction, and the second direction is perpendicular to the first direction.

[0103] As an example, the second direction is the up-down direction, such as Figure 3 As indicated by the arrow at b.

[0104] The fixed seat 12 and the main shaft 11 are supported by a second support portion 132 arranged in the second direction opposite to the traction wheel 2, so as to reduce the probability of the fixed seat 12 and the main shaft 11 overturning, thereby increasing the stability of the traction machine 100 of the embodiment of the utility model and reducing the probability of the traction machine 100 overturning of the embodiment of the utility model.

[0105] Combination Figure 3 and Figure 7As shown, specifically, the base 13 further includes a third reinforcing rib 133, one end of the third reinforcing rib 133 is connected to the second support portion 132, and the other end of the third reinforcing rib 133 is connected to the fixing seat 12. The third reinforcing rib 133 increases the connection strength and structural strength between the second support portion 132 and the fixing seat 12, and reduces the probability of damage to the second support portion 132 and the fixing seat 12.

[0106] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
