[0044] It should be understood that the terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. Unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" as used herein may also include the plural forms. The terms "comprising", "including", "containing", and "having" are inclusive and thus specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

[0045] Although the terms first, second, third, etc. may be used herein to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly dictates otherwise, terms such as "first", "second", and other numerical terms do not imply an order or sequence when used herein. Thus, the first element, component, region, layer, or section discussed below may be referred to as the second element, component, region, layer, or section without departing from the teachings of the example embodiments. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0046] In the present utility model, unless otherwise clearly specified and defined, terms such as "mounted", "connected", "coupled", "fixed", etc. shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or communicable with each other; it may be directly connected, or indirectly connected through an intermediate medium, and may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model may be understood according to specific circumstances.

For example, if the device in the figure is rotated, an element described as "below" or "beneath" another element or feature will then be oriented "above" or "over" the other element or feature. Thus, the exemplary term "below" can include both upward and downward orientations.

[0048] In the prior art, a steel wire rope is provided on a traction wheel of a traction machine and is connected to a car of an elevator system. The traction machine drives the steel wire rope to move through the traction wheel, so as to be able to drive the car to move, enabling the elevator system to operate. Among them, in the prior art, the brake disc and the traction wheel of the traction machine are integrally formed, or the brake disc and the traction wheel are assembled together. During the operation of the steel wire rope, the grease on the steel wire rope is likely to splash onto the brake disc, resulting in the lubrication of the brake disc, thereby causing a decrease in the braking torque of the brake disc, and further causing a decrease in the braking effect of the brake disc, thus making the elevator system prone to safety risks.

[0049] The present utility model aims to at least solve the problem that the grease on the steel wire rope in the prior art is likely to splash onto the brake disc.

[0050] To this end, an embodiment of the present utility model provides a machine base 110, which can block the grease splashed out from the first installation space 1 by at least one of a part of the first seat body 3 and a part of the second seat body 4, thereby being able to reduce the probability of the grease splashing from the first installation space 1 into the second installation space 2.

[0051] An embodiment of the present utility model further provides a traction machine 100 including the machine base 110 as described in the above embodiment, which can reduce the probability of the grease on the steel wire rope connected to the traction wheel 130 splashing onto the brake disc 120, thereby being able to reduce the probability of generating safety risks.

[0052] An embodiment of the present utility model further provides an elevator system including the traction machine 100 as described in the above embodiment, which can reduce the probability of generating safety risks.

[0053] The following Figures 1 to 8 describes the machine base 110, the traction machine 100 and the elevator system according to the embodiments of the present utility model.

[0054] Combined with Figure 2 and Figure 5As shown in the figure, the base 110 of the embodiment of the present utility model includes a first installation space 1, a second installation space 2, a first seat body 3, and a second seat body 4. The first installation space 1 is used for installing a brake disc 120. The second installation space 2 is used for installing a traction wheel 130. The first seat body 3 and the second seat body 4 are connected to each other, and a part of the structure of at least one of the first seat body 3 and the second seat body 4 is located between the first installation space 1 and the second installation space 2 and is used for separating the first installation space 1 and the second installation space 2.

[0055] It should be noted that the separation can be complete separation or partial separation.

[0056] The first installation space 1 and the second installation space 2 are separated by a part of the structure of at least one of the first seat body 3 and the second seat body 4. That is to say, the brake disc 120 installed in the first installation space 1 and the traction wheel 130 installed in the second installation space 2 can be separated, and a part of the structure of at least one of the first seat body 3 and the second seat body 4 can block the lubricating grease splashing in the first installation space 1, so as to reduce the probability of the lubricating grease splashing into the second installation space 2. Thus, the traction machine 100 with the base 110 of the embodiment of the present utility model can reduce the probability of the lubricating grease on the steel wire rope connected to the traction wheel 130 splashing onto the brake disc 120, and thereby can reduce the probability of generating safety risks.

[0057] As Figure 2 shown, in some specific embodiments, a part of the first seat body 3 is located between the first installation space 1 and the second installation space 2 and separates the first installation space 1 and the second installation space 2.

[0058] A part of the first seat body 3 blocks the lubricating grease splashing in the first installation space 1, so as to reduce the probability of the lubricating grease splashing into the second installation space 2. Thus, the traction machine 100 with the base 110 of the embodiment of the present utility model can reduce the probability of the lubricating grease on the steel wire rope connected to the traction wheel 130 splashing onto the brake disc 120, and thereby can reduce the probability of generating safety risks.

[0059] As Figure 9 shown, in some other specific embodiments, a part of the second seat body 4 is located between the first installation space 1 and the second installation space 2 and separates the first installation space 1 and the second installation space 2.

[0060] A part of the second seat body 4 blocks the lubricating grease splashing in the first installation space 1, so as to reduce the probability of the lubricating grease splashing into the second installation space 2. Thus, the traction machine 100 with the base 110 of the embodiment of the present utility model can reduce the probability of the lubricating grease on the steel wire rope connected to the traction wheel 130 splashing onto the brake disc 120, and thereby can reduce the probability of generating safety risks.

[0061] As Figure 10 shown, in some other specific embodiments, part of the first base body 3 and part of the second base body 4 are located between the first installation space 1 and the second installation space 2 and separate the first installation space 1 and the second installation space 2.

[0062] The grease splashing in the first installation space 1 is blocked by part of the first base body 3 and part of the second base body 4, so as to reduce the probability of grease splashing into the second installation space 2. Thus, the traction machine 100 with the machine base 110 of the embodiment of the present utility model can reduce the probability of the grease on the steel wire rope connected to the traction wheel 130 splashing onto the brake disc 120, thereby reducing the probability of generating safety risks.

[0063] As Figure 5 shown, the traction machine 100 of the embodiment of the present utility model includes the machine base 110, the brake disc 120 and the traction wheel 130 as described in the above embodiments. The brake disc 120 is installed in the first installation space 1. The traction wheel 130 is installed in the second installation space 2.

[0064] Since the brake disc 120 is installed in the first installation space 1 and the traction wheel 130 is installed in the second installation space 2, the brake disc 120 and the traction wheel 130 are separated by part of the structure of at least one of the first base body 3 and the second base body 4, so that the grease splashing out from the steel wire rope provided on the traction wheel 130 can be blocked, thereby reducing the probability of grease splashing onto the brake disc 120, further reducing the probability of the braking torque of the brake disc 120 decreasing, and reducing the probability of the braking effect of the brake disc 120 decreasing.

[0065] In some alternative embodiments, part of the first base body 3 can block all parts of the traction wheel 130, thereby reducing the probability of grease splashing onto the brake disc 120.

[0066] In some other alternative embodiments, part of the first base body 3 can block a part of the traction wheel 130, thereby reducing the probability of grease splashing onto the brake disc 120.

[0067] In some other alternative embodiments, part of the second base body 4 can block all parts of the traction wheel 130, thereby reducing the probability of grease splashing onto the brake disc 120.

[0068] In some other alternative embodiments, part of the second base body 4 can block a part of the traction wheel 130, thereby reducing the probability of grease splashing onto the brake disc 120.

[0069] In some other optional embodiments, part of the first seat body 3 and part of the second seat body 4 can cover the entire portion of the traction sheave 130 , thereby reducing the probability of grease splashing onto the brake disc 120 .

[0070] In some other optional embodiments, part of the first seat body 3 and part of the second seat body 4 can shield a portion of the traction sheave 130 , thereby reducing the probability of grease splashing onto the brake disc 120 .

[0071] The elevator system of the embodiment of the utility model includes the traction machine 100 of the above embodiment. The probability of grease splashing onto the brake disc 120 can be reduced, thereby reducing the probability of the braking torque of the brake disc 120 decreasing, and reducing the probability of the braking effect of the brake disc 120 decreasing, so that the elevator system of the embodiment of the utility model can reduce the probability of safety risks.

[0072] In some specific embodiments, the elevator system further includes a wire rope, a counterweight and a car. The traction machine 100, the car, the counterweight and the wire rope are all arranged in the elevator shaft. The car and the counterweight are arranged on both sides of the traction wheel 130 along the radial direction of the traction wheel 130, and the wire rope includes a first rope segment, a second rope segment and a third rope segment. The third rope segment is arranged on the traction wheel 130, and the first rope segment and the second rope segment both extend along the second direction. One end of the first rope segment is connected to the car, the other end of the first rope segment is connected to one end of the third rope segment, one end of the second rope segment is connected to the counterweight, and the other end of the second rope segment is connected to the other end of the third rope segment. The traction wheel 130 determines the output torque according to the weight of the car and the weight of the counterweight, so as to drive the car to operate.

[0073] The first direction is parallel to the rotation axis of the traction wheel 130 , the second direction is the up-down direction, the third direction is the horizontal direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0074] When the brake disc 120 is braked, the grease of the third rope segment can be blocked after splashing out, thereby reducing the probability of grease splashing onto the brake disc 120, and further reducing the probability of the braking torque of the brake disc 120 decreasing, and reducing the probability of the braking effect of the brake disc 120 decreasing, so that the elevator system of the embodiment of the utility model can reduce the probability of safety risks.

[0075] like Figure 5 As shown, in some embodiments, the traction machine 100 further includes a rotating shaft 140 , which extends along a first direction and is rotatably disposed on the machine base 110 , and the traction wheel 130 and the brake disc 120 are both drivingly connected to the rotating shaft 140 .

[0076] The brake disc 120 and the traction wheel 130 are both connected to the rotating shaft 140. When the brake disc 120 is braked, a braking torque is generated, and the braking torque acts on the traction wheel 130 through the rotating shaft 140 so that the traction wheel 130 can be braked. By providing the rotating shaft 140, the brake disc 120 can be spaced from the traction wheel 130 and the traction wheel 130 can be braked.

[0077] Combined with Figure 2 、 Figure 3 and Figure 5 As shown, in some embodiments, the first housing 3 includes a first connecting portion 31 and an end cover 32. The end cover 32 is disposed between the first installation space 1 and the second installation space 2 and separates the first installation space 1 and the second installation space 2. That is, a part of the first housing 3 in the embodiments of the present invention separates the first installation space 1 and the second installation space 2. The first connecting portion 31 is disposed between the first installation space 1 and the second installation space 2 and surrounds the end cover 32.

[0078] The end cover 32 blocks the lubricating grease splashing in the first installation space 1, so as to reduce the probability of the lubricating grease splashing into the second installation space 2. The first connecting portion 31 is used to install the end cover 32.

[0079] Specifically, the rotating shaft 140 passes through the end cover 32. A part of the rotating shaft 140 is located in the first installation space 1 and is in transmission connection with the brake disc 120, and another part of the rotating shaft 140 is located in the second installation space 2 and is in transmission connection with the traction wheel 130. By providing the rotating shaft 140, the brake disc 120 can be spaced from the traction wheel 130 and the traction wheel 130 can be braked.

[0080] As Figure 8 shown, in other embodiments, the first housing 3 includes a first connecting portion 31 and a blocking portion 36. The blocking portion 36 is disposed between the first installation space 1 and the second installation space 2 and separates the first installation space 1 and the second installation space 2. The first connecting portion 31 surrounds the blocking portion 36.

[0081] The first connecting portion 31 blocks the lubricating grease splashing in the first installation space 1, so as to reduce the probability of the lubricating grease splashing into the second installation space 2.

[0082] Combined with Figure 2 and Figure 3As shown, in some embodiments, the first connecting portion 31 defines an installation hole 311 which communicates with the second installation space 2. The installation hole 311 is configured to allow the traction wheel 130 to enter or exit the second installation space 2. That is to say, the installation hole 311 is configured to be passed through by the traction wheel 130 so that the traction wheel 130 can enter the second installation space 2, and the installation hole 311 is also configured to be passed through by the traction wheel 130 so that the traction wheel 130 can exit the second installation space 2. An end cap 32 is disposed in the installation hole 311 to seal the installation hole 311, and the end cap 32 is detachably connected to the first connecting portion 31.

[0083] When installing the traction wheel 130, the traction wheel 130 is made to enter the second installation space 2 through the installation hole 311 for installation, and the end cap 32 is installed. When disassembling the traction wheel 130, the end cap 32 is disassembled so that the traction wheel 130 exits the second installation space 2 through the installation hole 311.

[0084] By detachably connecting the end cap 32 to the first connecting portion 31 and enabling the traction wheel 130 to enter and exit the second installation space 2 through the installation hole 311, it is convenient to install and disassemble the traction wheel 130.

[0085] Combined Figure 5 and Figure 6 As shown, in some embodiments, the end cap 32 includes a third connecting portion 321 and a fourth connecting portion 322 which are connected to each other. The fourth connecting portion 322 defines a connecting hole 323 for installing the rotating shaft 140. The third connecting portion 321 and the fourth connecting portion 322 are oppositely arranged in the radial direction of the connecting hole 323. The third connecting portion 321 is connected to the first connecting portion 31, and at least part of the fourth connecting portion 322 is located between the third connecting portion 321 and the second installation space 2 along the axial direction of the connecting hole 323.

[0086] That is to say, along the axial direction of the connecting hole 323, at least part of the fourth connecting portion 322 is closer to the second installation space 2 relative to the third connecting portion 321, that is, along the axial direction of the connecting hole 323, at least part of the fourth connecting portion 322 is closer to the traction wheel 130 relative to the third connecting portion 321. Thus, the distance between the fourth connecting portion 322 and the traction wheel 130 can be reduced, and thereby the deflection of the rotating shaft 140 can be reduced.

[0087] Exemplarily, the main shape of the end cap 32 is conical, so that the end cap 32 is reasonably stressed.

[0088] Furthermore, reinforcing ribs are provided on both sides of the end cap 32 in the first direction, so that the structural strength of the end cap 32 can be increased.

[0089] Such as Figure 5As shown, in some embodiments, the first seat body 3 further includes a second connecting portion 33 connected to the first connecting portion 31. The second connecting portion 33 is located on the side of the first connecting portion 31 away from the first installation space 1, and the second connecting portion 33 covers the second installation space 2. The traction wheel 130 can be protected by the second connecting portion 33.

[0090] Combined with Figure 2 、 Figure 3 and Figure 5 As shown, in some embodiments, the second seat body 4 is located on the side of the second installation space 2 away from the first installation space 1. The second seat body 4 defines an installation cavity 41 for installing the drive assembly 150. That is to say, the installation cavity 41 is located on the side of the second installation space 2 away from the first installation space 1.

[0091] By making the installation cavity 41 located on one side of the traction wheel 130, the heat dissipation effect of the drive assembly 150 can be increased. Since heat is generated during the braking process of the brake disc 120, arranging the drive assembly 150 along the first direction on the side of the traction wheel 130 away from the brake disc 120 can increase the heat dissipation effect of the drive assembly 150 and the brake disc 120.

[0092] As Figure 5 shown, in some embodiments, the second seat body 4 includes a main body 44 and a fifth connecting portion 45. The fifth connecting portion 45 is connected to the main body 44 and is used for connecting to the rotating shaft. At least part of the fifth connecting portion 45 is located between the main body 44 and the second installation space 2 along the axial direction of the connecting hole 323.

[0093] That is to say, along the axial direction of the connecting hole 323, at least part of the fifth connecting portion 45 is closer to the second installation space 2 relative to the main body 44, that is, along the axial direction of the connecting hole 323, at least part of the fifth connecting portion 45 is closer to the traction wheel 130 relative to the main body 44. Thus, the distance between the fifth connecting portion 45 and the traction wheel 130 can be reduced, and the deflection of the rotating shaft 140 can be reduced.

[0094] Combined with Figure 5 and Figure 7 As shown, in some embodiments, the drive assembly 150 includes a stator 151 and a rotor 152. The stator 151 includes a stator base 1511 and windings 1512 arranged circumferentially around the stator base 1511. The rotor 152 is located between the stator base 1511 and the traction wheel 130 along the first direction. The stator base 1511 defines a heat dissipation cavity 15111, and the heat dissipation cavity 15111 is open at one end away from the traction wheel 130 along the first direction; the rotor 152 is sleeved on the rotating shaft 140, and a third installation space 1521 is defined inside the rotor 152, and at least part of the stator base 1511 and at least part of the windings 1512 are arranged inside the third installation space 1521.

[0095] The drive assembly 150 with an outer rotor structure has a higher power density.

[0096] The winding 1512 is disposed on the stator seat 1511 , and the stator seat 1511 defines a heat dissipation cavity 15111 , so that the heat generated by the winding 1512 can be discharged in time through the heat dissipation cavity 15111 , thereby enabling the heat generated by the driving component 150 to be discharged in time.

[0097] Combination Figure 5 and Figure 7 As shown, in some embodiments, a plurality of first heat dissipation ribs 15112 are arranged in the heat dissipation cavity 15111, and the plurality of first heat dissipation ribs 15112 are arranged on the peripheral wall of the heat dissipation cavity 15111 at intervals along the circumference of the rotor 152, and the extension direction of each first heat dissipation rib 15112 is consistent with the first direction or is arranged at an angle to the first direction.

[0098] The heat dissipation area is increased by the first heat dissipation rib 15112, thereby further increasing the heat dissipation effect on the drive assembly 150. By making the extension direction of the first heat dissipation rib 15112 consistent with the first direction or arranged at an angle to the first direction, the first heat dissipation rib 15112 can more efficiently discharge heat through the heat dissipation cavity 15111 along the first direction away from the opening at one end of the traction sheave 130.

[0099] like Figure 3 As shown, in some embodiments, the second seat body 4 is provided with a plurality of second heat dissipation ribs 46, each second heat dissipation rib 46 extends along the circumference of the rotor 152, the plurality of second heat dissipation ribs 46 are arranged at intervals along the first direction, and the plurality of second heat dissipation ribs 46 are correspondingly arranged on the radially outer side of the rotor 152.

[0100] The rotor 152 is cooled by the second heat dissipation ribs 46 , thereby further increasing the heat dissipation effect of the drive assembly 150 .

[0101] In the prior art, the stator and rotor of the drive assembly need to be assembled together for installation. After the stator and rotor are assembled together, they are heavy, which makes it difficult to assemble the drive assembly in the prior art, and also makes it difficult to disassemble the drive assembly in the prior art.

[0102] like Figure 5 As shown, in some embodiments, an installation opening 1522 is provided at one end of the third installation space 1521 along the first direction away from the traction wheel 130, and at least a portion of the stator seat 1511 and at least a portion of the winding 1512 are configured to be able to be arranged in the third installation space 1521 through the installation opening 1522, and at least a portion of the stator seat 1511 and at least a portion of the winding 1512 are configured to be able to be separated from the third installation space 1521 through the installation opening 1522.

[0103] At least part of the stator base 1511 and at least part of the winding 1512 can enter or exit the third installation space 1521 through the installation opening 1522. When assembling the drive assembly 150, the rotor 152 can be assembled first, and then the stator 151 can be assembled. That is to say, the drive assembly 150 can be assembled in a split manner, thereby reducing the assembly difficulty of the drive assembly 150. When disassembling the drive assembly 150, the stator 151 can be disassembled first, and then the rotor 152 can be disassembled. That is to say, the drive assembly 150 can be disassembled in a split manner, thereby reducing the disassembly difficulty of the drive assembly 150.

[0104] Thus, by providing the third installation space 1521 and the installation opening 1522, at least part of the stator base 1511 and at least part of the winding 1512 can be disposed in the third installation space 1521 through the installation opening 1522 or can be detached from the installation space through the installation opening 1522, facilitating the installation and disassembly of the drive assembly 150.

[0105] Combined Figure 5 and Figure 7 As shown, in some embodiments, the stator base 1511 includes a first mounting portion 15113 and a first mounting portion 15113 that are connected to each other. The winding 1512 is sleeved on one end of the first mounting portion 15113 along the radial direction of the traction wheel 130. The other end of the first mounting portion 15113 along the radial direction of the traction wheel 130 defines a heat dissipation cavity 15111. The first mounting portion 15113 is disposed at one end of the first mounting portion 15113 that faces away from the traction wheel 130 in the first direction, and the first mounting portion 15113 is connected to the machine base 110.

[0106] When installing the winding 1512 and the stator base 1511, the winding 1512 is sleeved on the first mounting portion 15113, so that the winding 1512 and the stator base 1511 can be installed synchronously, simplifying the installation steps of the winding 1512 and the stator base 1511 and reducing the installation difficulty of the winding 1512 and the stator base 1511.

[0107] In addition, by disposing the winding 1512 at one end of the first mounting portion 15113 and making the other end of the first mounting portion 15113 define the heat dissipation cavity 15111, the heat dissipation effect of the heat dissipation cavity 15111 on the winding 1512 can be improved, enabling the heat generated by the winding 1512 to be discharged in time through the heat dissipation cavity 15111.

[0108] As Figure 5 shown, in some alternative embodiments, the rotor 152 is connected to the rotating shaft 140 through a first expansion sleeve 153.

[0109] By setting the first expansion sleeve 153, the rotor 152 can be connected to the rotating shaft 140, thereby avoiding the need to machine a keyway on the rotating shaft 140 and improving the strength of the rotating shaft 140.

[0110] In addition, by setting the first expansion sleeve 153, the rotor 152 and the rotating shaft 140 can be quickly assembled and disassembled, facilitating the installation and removal of the rotor 152 and the rotating shaft 140.

[0111] As Figure 5 shown, in some further embodiments, the brake disc 120 is connected to the rotating shaft 140 through a second expansion sleeve 121.

[0112] By setting the second expansion sleeve 121, the brake disc 120 can be connected to the rotating shaft 140, thereby avoiding the need to machine a keyway on the rotating shaft 140 and improving the strength of the rotating shaft 140.

[0113] In addition, by setting the second expansion sleeve 121, the brake disc 120 and the rotating shaft 140 can be quickly assembled and disassembled, facilitating the installation and removal of the brake disc 120 and the rotating shaft 140.

[0114] As Figure 5 shown, further, the traction wheel 130 is connected to the rotating shaft 140 through a third expansion sleeve 131.

[0115] By setting the third expansion sleeve 131, the traction wheel 130 can be connected to the rotating shaft 140, thereby avoiding the need to machine a keyway on the rotating shaft 140 and improving the strength of the rotating shaft 140.

[0116] In addition, by setting the third expansion sleeve 131, the traction wheel 130 and the rotating shaft 140 can be quickly assembled and disassembled, facilitating the installation and removal of the traction wheel 130 and the rotating shaft 140.

[0117] As Figure 5 shown, in some embodiments, the traction machine 100 further includes a first bearing 5, an end cover 32 is sleeved on the first bearing 5, the first bearing 5 is sleeved on the rotating shaft 140, and an oil seal 35 is provided on one side of the first bearing 5 close to the brake disc 120.

[0118] By providing the oil seal 35, the first bearing 5 and the brake disc 120 can be separated, thereby reducing the probability of contact between the lubricating substance in the first bearing 5 and the brake disc 120. Among them, the lubricating substance can be lubricating oil, grease, etc.

[0119] In addition, through the oil seal 35, the first bearing 5 can be sealed, thereby reducing the probability of contact between the lubricating substance in the first bearing 5 and other components.

[0120] As Figure 5As shown, further, a oil seal 35 is provided on the side of the first bearing 5 facing away from the brake disc 120.

[0121] Providing the oil seal 35 on the side of the first bearing 5 facing away from the brake disc 120 can further seal the first bearing 5, thereby further reducing the probability of the lubricating substance in the first bearing 5 coming into contact with other components.

[0122] As Figure 5 shown, in some embodiments, the traction machine 100 further includes a second bearing 6. The second bearing 6 is sleeved on the rotating shaft 140, the machine base 110 is sleeved on the second bearing 6, and the traction wheel 130 is located between the first bearing 5 and the second bearing 6.

[0123] In the traction machine 100 of the embodiment of the present utility model, the traction wheel 130 and the brake disc 120 are separately provided, so the distance between the first bearing 5 and the second bearing 6 is reduced. The traction wheel 130 is connected to the car, and the load-bearing of the traction wheel 130 is large. Reducing the distance between the first bearing 5 and the second bearing 6 can make the distance between the first bearing 5 and the second bearing 6 relative to the traction wheel 130 smaller, thereby reducing the deflection of the rotating shaft 140, that is to say, reducing the deformation amount of the rotating shaft 140.

[0124] As Figure 5 shown, further, oil seals 35 are provided at both ends of the second bearing 6 in the first direction. The second bearing 6 can be sealed through the oil seals 35, thereby reducing the probability of the lubricating substance in the first bearing 5 coming into contact with other components.

[0125] Specifically, one end of the second connecting portion 33 is connected to the first connecting portion 31, and the other end of the second connecting portion 33 is connected to the second seat body 4.

[0126] Increasing the connection strength between the first connecting portion 31 and the second seat body 4 through the second connecting portion 33 makes the machine base 110 of the embodiment of the present utility model not easily damaged.

[0127] As Figure 3As shown in the figure, further, the second connecting portion 33 includes a first boss 331, two cross beams 332, and two arc connecting segments 333. One end of the first boss 331 in the first direction is connected to the first connecting portion 31, and the other end of the first boss 331 in the first direction is connected to the second seat body 4. The two cross beams are located on both sides of the first boss 331 in the third direction. The two cross beams 332 both extend along the first direction. One end of each cross beam 332 in the first direction is connected to the first connecting portion 31, and the other end of each cross beam 332 in the first direction is connected to the second seat body 4. Each cross beam 332 is located below the first boss 331. The two arc connecting segments 333 are located at both ends of the first boss 331 in the third direction. One end of each arc connecting segment 333 in the first direction is connected to the first connecting portion 31, and the other end of each arc connecting segment 333 in the first direction is connected to the second seat body 4. One end of each arc connecting segment 333 in the second direction is connected to the first boss 331, and the other end of each arc connecting segment 333 in the second direction is connected to the corresponding cross beam 332. Wherein, the first direction is parallel to the rotation axis of the traction wheel 130, the second direction is the up and down direction, the third direction is the horizontal direction, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0128] The connection strength between the first seat body 3 and the second seat body 4 is increased through the cross beam 332 and the first boss 331, and the traction wheel 130 is covered by the cross beam 332, the first boss 331, and the arc connecting segment 333 to protect the traction wheel 130.

[0129] Specifically, reinforcing ribs are provided between one end of each cross beam 332 in the first direction and the first connecting portion 31, and between the other end of each cross beam 332 in the first direction and the second seat body 4, thereby further increasing the connection strength between the first connecting portion 31 and the second seat body 4.

[0130] As Figure 3 shown, further, the second connecting portion 33 further includes two first lifting ring portions 334. Each first lifting ring portion 334 is used for being hoisted. The two first lifting ring portions 334 are respectively arranged on the two arc connecting segments 333. Each first lifting ring portion 334 is connected to the corresponding cross beam 332 and each first lifting ring portion 334 is connected to the first boss 331, thereby increasing the connection strength between the first boss 331, the cross beam 332, and the arc connecting segment 333.

[0131] As Figure 3 shown, further, the second seat body 4 includes two second lifting ring portions 42. Each second lifting ring portion 42 is suitable for being hoisted. The two second lifting ring portions 42 are arranged in one-to-one correspondence and at intervals with the two first lifting ring portions 334 in the first direction, so that the traction machine 100 can maintain balance during the hoisting process.

[0132] As Figure 3 shown, in some further embodiments, the first boss 331 is located above the traction wheel 130. The first boss 331 is provided with a first through hole 3311, and the first through hole 3311 is disposed opposite to the traction wheel 130 in the second direction. By providing the first through hole 3311, it is convenient to dispose the wire rope on the traction wheel 130 through the first through hole 3311.

[0133] As Figure 3 shown, in some specific embodiments, the second connecting portion 33 includes a second boss 335. The second boss 335 is disposed opposite to the first boss 331 in the second direction. One end of the second boss 335 in the first direction is connected to the first seat body 3, and the other end of the second boss 335 in the first direction is connected to the second seat body 4, so as to increase the connection strength between the first seat body 3 and the second seat body 4. The second boss 335 is provided with a second through hole 3351, and the second through hole 3351 is disposed opposite to the traction wheel 130 in the second direction. The wire rope can pass through the second through hole 3351 to penetrate out of the second connecting portion 33 and be connected to the car, so that the structure of the machine base 110 of the embodiment of the present utility model is reasonable.

[0134] As Figure 3 shown, in some specific embodiments, the second connecting portion 33 further includes a rib 336. One end of the rib 336 in the first direction is connected to the first connecting portion 31, and the other end of the rib 336 in the first direction is connected to the second seat body 4. The rib 336 is located above the second boss 335, and the lower end of the rib 336 is connected to the second boss 335, so as to strengthen the structural strength of the second boss 335 through the rib 336.

[0135] As Figure 2 shown, in some specific embodiments, the second seat body 4 is provided with heat dissipation holes 43, and the heat dissipation holes 43 are communicated with the installation cavity 41, so as to increase the heat dissipation effect of the installation cavity 41 through the heat dissipation holes 43.

[0136] In some embodiments, the first seat body 3 and the second seat body 4 are integrally formed parts.

[0137] By integrally forming the first seat body 3 and the second seat body 4, the first seat body 3 and the second seat body 4 have high strength and stiffness, so as to improve the safety and reliability of the machine base 110 of the embodiment of the present utility model.

[0138] As Figure 1 shown, in some embodiments, the first seat body 3 includes an installation boss 34 for installing the brake 160, and the installation boss 34 is located in the first installation space 1.

[0139] By providing the installation boss 34, it is convenient to install the brake 160.

[0140] Specifically, the mounting boss 34 is connected to the first connecting portion 31, and the mounting boss 34 and the first connecting portion 31 are integrally formed.

[0141] The integral formation of the mounting boss 34 and the first connecting portion 31 gives the mounting boss 34 relatively high rigidity and strength, so that when the brake 160 is braking, the deformation of the mounting boss 34 is relatively small.

[0142] As Figure 4 shown, in some embodiments, the traction machine 100 includes a brake 160, and the brake 160 is mounted on the mounting boss 34.

[0143] The brake 160 is mounted on the mounting boss 34 with relatively high rigidity and strength. When the brake 160 is braking, the deformation of the mounting boss 34 is relatively small, so that the displacement of the brake 160 is relatively small, and further the braking effect of the brake 160 can be improved.

[0144] As Figure 4 shown, specifically, there are six mounting bosses 34, and the six mounting bosses 34 are arranged at intervals along the circumferential direction of the brake disc 120. There are six brakes 160, and the six brakes 160 are respectively mounted on the six mounting bosses 34 in one-to-one correspondence.

[0145] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
